Piranha ¼-12 Operators/Owner’s Manual

2. Introduction

The Piranha Maxi Shear is a heavy steel constructed, high performance hydraulic powered

machine that provides you several important advantages surpassing most other shears in today’s

market. The Piranha’s single hydraulic cylinder and mechanical linkage system provides the

following advantages: 1. The upper shear blade moves parallel to the lower blade thus providing

maximum blade life, 2. Full length gibbs guide the ram laterally and front-to-back at all times

during the shearing process thus increasing rigidity, shearing accuracy, and blade life, 3. The

straight-line shearing action improves shearing accuracy in all metal thickness.

The machine arrives fully assembled requiring only hydraulic oil and electrical power to become

fully operational. The heavy steel “C” frames, interlocking cross members, ram, and bed provide

the rigidity and resistance to deflection that is necessary for accurate performance. State-of-the-

art, maintenance-free, aerospace bearings provide high load capacity and low friction in the form

of a thin walled sleeve. They are completely non-metallic and require no lubrication.

Other standard features include: Full length hardened slides with non-metallic ways, variable cut

length adjustment, hydraulic hold downs with replaceable polyurethane shoes, heavy duty,

inch/mm motorized, disappearing back gauge with Go-To features and .100” retract feature on

each stroke. A 53" squaring arm with recessed inch/mm scale, four-edge high chrome, high

carbon shear blades top and bottom.

Proper understanding and application of the information and procedures given in this manual will

aid in establishing a preventative maintenance program and provide assistance for correcting

malfunctions that may occur in the machine. The repair parts list provides information for part

procurement and assembly breakdowns to aid in disassembly and re-assembly for repair parts

installation. Please have machine serial number available when contacting the factory for service

or repair parts.

3. Installation

BEFORE INSTALLING THIS SHEAR, READ AND UNDERSTAND THE SHEAR

MANUAL WITH PARTICULAR ATTENTION TO “SAFETY TIPS FOR MAINTENANCE

PERSONNEL” THE CURRENT ANSI B11.4 STANDARD-“SAFETY REQUIREMENTS

FOR THE CONSTRUCTION, CARE AND USE OF SHEARS.” Copies can be ordered

from: American National Standards Institute, 1430 Broadway, New York, New York

10018

3.1. Unpacking

CAUTION: THE SHEAR IS HEAVY IN FRONT. GUARD AGAINST TIPPING UNTIL

ANCHOR BOLTS ARE SECURED.

This machine was carefully packaged at the factory to avoid damage during shipment, should

any accidental damage occur contact the responsible freight company immediately and report

the damage. Indicate any damage on the Bill of Lading. All Warranty information included

in this packet must be returned to the factory.

Figure 1: Lifting Lug Location

The Piranha 1/4-12 Shear must only be lifted using a crane, and the lifting lugs located in

front of the hydraulic oil tank on top of the machine. Do not lift the machine from the bottom

(forklift or jack) as the machine is top and front heavy and can tip resulting in serious bodily

harm or death. Lifting the machine from the bottom can also result in machine damage.

WARNING: CHECK BLADE GAP BEFORE CYCLING MACHINE.

FAILURE TO DO SO MAY CAUSE BLADE DAMAGE

Piranha ¼-12 Operators/Owner’s Manual

3.2. Placement

Piranha recommends that the machine be placed on a reasonably level concrete foundation

suitable to support the shear’s total weight and in accordance with local building codes. The

machine should be placed on a single concrete pad free of cracks and seams. Prior to

anchoring or setting, the shear should be leveled and shimmed. Section 3.4 of this manual

discusses leveling the machine. Anchoring can be accomplished using suitable masonry

anchors. Use the machine as a template for anchoring hole locations. Placement of the

machine should allow easy access around the machine for the operator and maintenance

personnel. For safe operation placement should allow tooling to be installed onto the bed

from the end of the machine.

It is recommended that a minimum four-foot area around the Piranha 1/4-12 Shear be

provided.

3.2.1. Initial leveling

CAUTION: THE SHEAR IS HEAVY IN FRONT. GUARD AGAINST TIPPING

BEFORE AND DURING LEVELING.

Level adjusting screws are only provided on the rear feet. The Piranha 1/4-12 Shear

must be placed on four steel pads: 2 each 6" x 6" x ¾" for the front feet and 2 each 6"

x 6" x ½" for the rear feet. These pads are provided with the shear.

3.3. Cleaning

Clean the bed surface, with a mild solvent so as not to damage the paint finish on the

machine. The main cylinder rod must also be free of contaminants. Any contaminants left on

the cylinder rod may damage the chrome finish and related hydraulic seals. The cylinder rod

must be clean and dry. Wipe down the rest of the shear with a mild cleaning solution.

3.4. Precision Leveling

The Piranha 1/4-12 Shear must be leveled precisely prior to operation. The following steps

represent the typical leveling procedure. These instructions must be followed to avoid

damaging the machine.

Using a machinist level, having an accuracy of one-half thousandths of an inch per foot, place

the level facing front to back on the left side of the shear squaring arm. Adjust the rear

leveling bolt until the bubble on the level is centered. Then, repeat for the right side, placing

the level on the outside of the table. It’s very important that the sides of the table be parallel

to each other with no crosscorner binding of the table. Once the machine is level, place

shims having a thickness equal to the gap, between the base plate and the bottom of the shear

foot. After your shim stock is in place release the adjusting bolts and recheck the level to

ensure that the left and right side of the machine have remained parallel. Tighten the

anchoring bolts and recheck the level of the shear. If necessary, re-adjust the shim pack

height if the shear has moved during anchoring. Do not cycle machine before it’s leveled, or

you may damage the shear blades!

NOTE:

Re-check machine level after the first 200 hours of operation, and at regular intervals.

Consult the Maintenance section for additional information.

Piranha ¼-12 Operators/Owner’s Manual

3.5.1 Motor Rotation

Electrical connection of the 3-phase systems requires proper phasing. When connecting the

press to a 3-phase power source, the rotational direction of the pump drive motor must be

correct. The rotational direction may be observed by removing the orange cover plate located

on the pump/motor adapter. The motor must rotate in the direction of the arrow on the motor.

Before operating the machine insure the cover is securely in place.

A licensed electrician should perform all electrical connections.

! Warning - The control transformer is for machine operation only. Do not use the

machine transformer to power any secondary devices.

3.6. Hydraulic

Before applying power to the Piranha 1/4-12 Shear, the hydraulic reservoir must be filled

with oil. To fill the reservoir, locate and remove the filler/breather cap on top of the reservoir.

Fill the reservoir with Mobil DTE-13 or ISO32 equivalent, filtered to an ISO 17/15/13-

cleanliness level. The proper oil level is between the red and black lines of the sight gauge

found on the rear of the reservoir (See Figure 3). Do not over fill the reservoir. Replace the

filler/breather cap.

Piranha ¼-12 Operators/Owner’s Manual

will display on the LED readout. Depress the GO button to position the

backgague to 12.375”

WARNING: DO NOT USE PRESET STATION #0 for programming

preset stations.

4.4.2.3. Calibration / Re-calibration

To calibrate the backgague to an actual position, use the following

procedure:

1. Measure the actual distance from the lower blade edge to the

backgauge bar. (Example 20 inches) Press (CLR), (2) (0)(.) (0) (0)

Press and hold (CAL) until flashing stops. The display will show the

calibrated value (20.000”)

2. Enter a short distance, (i.e. 3”), press GO button, backgauge will

position to 3”.

3. Shear a piece of metal and measure the sheared part with a caliper.

Enter the measured dimension onto the keypad, press and hold CAL

until the flashing stops. Verify the accuracy by shearing another

part. Repeat step # 3 if minor adjustments are required.

IMPORTANT:

DO NOT DEPRESS THE STOP BUTTON WHEN THE SHEAR

BACKGAUGE IS IN MOTION. This will cause the backgague to loose

calibration and will require recalibration.

ENSURE SHEAR BLADE/RAM IS AT THE TOP OF STROKE before

turning machine off. Failure to do so will require backgague recalibration.

NOTE: If the backgauge begins “Hunting” for position (continuously goes past the target position),

either the drive chain (FIG 25A & B) is too loose or the “Drag Block” (Fig 25C & E) has become

loose. To adjust the drag block, loosen the jam nut (FIG 25E) and tighten the adjusting screw

clockwise in 1/16 rotations until the “Hunting” stops.

WARNING: Over adjusting the tightness on the drag block will cause premature motor failure or

electrical over current which will result in a blown fuse.

Piranha ¼-12 Operators/Owner’s Manual

5. Shear Operation

BEFORE OPERATING THE SHEAR, READ AND UNDERSTAND THE CURRENT

ANSI B11.4 STANDARD. CAUTION: READ AND UNDERSTAND THIS ENTIRE

MANUAL BEFORE PLACING SHEAR IN OPERATION.

WARNING: CHECK BLADE GAP BEFORE CYCLING MACHINE.

FAILURE TO DO SO MAY CAUSE BLADE DAMAGE

! Always review the instructions provided in this manual and observe shearing safety rules!

! Insure that no tools, bolts or other obstructions are in the knife area prior to operating the

shear.

! Locate any available safety handling tools required.

! Keep the floor and surrounding area clean and free of obstruction, debris and oil.

5.1. Setting the Shear Blades / Ram Gib Check And Adjustment Procedure:

The following procedure for blade adjustment is recommended:

1. Verify that the shear is level.

2. ALWAYS check gib clearance before adjusting blade clearance.

Checking gib clearance:

3. Position the shear ram at the top of stroke so the slides are in full contact with the gibs.

4. Remove Side Cover Guards from gib area.

5. Ensure clearance exists between the Blades to prevent blade clash when the blades cross.

6. When checking slide clearances, it is easiest to perform the checks from the rear of the

machine. When checking the bottom gib clearances, the low side (left side) and the high side

(right side) should be checked 3” from the bottom of the gib assembly. When checking the

clearances at the top of the gibs, the low (left side) should be checked from the top gib

assembly. The high side (right side) should be checked from the top gib assembly:

7. With a feeler gauge, check the clearance at the bottom of the slide. The feeler gauge must fit

between the bearing material and the front side of the ram slide. Acceptable clearance is .003-

.004”

8. Repeat this measuring procedure for the other side of the machine.

Adjusting gib clearance:

9. To tighten clearances, loosen the 3/8” jam nut located at the bottom of the slide assembly.

Using an Allen wrench rotate the setscrew clockwise until correct clearance is achieved. Lock

jam nut on setscrew.

10. Repeat this procedure for the other side of the machine if adjustment is required.

11. To check the clearance on the top of the slide, insert a feeler gauge between the bearing

surface on the rear side of the ram slide. Acceptable clearance is .003”-.004”

12. To tighten clearances, loosen the 3/8” jam nut located at the top of the slide assembly. Using

an Allen wrench rotate the setscrew clockwise until correct clearance is achieved. Lock jam

nut on setscrew.

Piranha ¼-12 Operators/Owner’s Manual

13. Repeat this procedure for the other side of the machine if adjustment is required.

14. Re-adjust the remaining setscrews by tightening the screws with a firm “snug”. Tighten the

jam nuts.

15. After all the adjustments have been made, re-check the clearances to ensure that they have not

moved during the adjustment process.

ADJUSTING SIDE THRUST BEARINGS:

1. To set the clearance, loosen the top and bottom jam nuts. Using an Allen wrench rotate the

top setscrew clockwise until the set screws stops firmly. Back off setscrew and re-tighten to a

light stop. Lock jam nut on setscrew.

2. Repeat this procedure for the bottom adjusting screw.

3. Re-adjust the remaining setscrews by tightening the screws to a light “snug”. Tighten the jam

nuts.

4. Repeat this procedure for the other side of the machine.

5. Grease the gibs after adjustments are complete. Cycle the ram while greasing the gibs.

CHECKING AND ADJUSTING SHEAR BLADE CLEARANCE:

Nominal knife clearance is typically .004” at the ends and .002” in the center of the shear.

The feeler gauge should have a slight resistance or “drag” as it is slid across the blade intersect

point.

1. Jog the ram down until the knives intersect before reaching the first hold down.

2. Check clearance at this point and then jog ram down and check clearance at the center of the

machine and then at the far end or (high side) of the machine.

3. To adjust blade gap clearance at each end of the blade, loosen top 4 bed bolts, two on each end

of the table, and four table stabilizer bolts. Two bolts are located at the bottom of the vertical

table stiffener on the inside of the side frame. The second set of stabilizer bolts are located on

the outside bottom middle of the side frame. Adjust table in or out by adjusting the

“push/pull” table adjusting bolts located in a machined pocket on the table ends.

4. Be sure that the blade gap in the center of the shear will not interfere when adjusting the end

clearance. When correct blade clearance is achieved, re-tighten the four table bolts to 300 ft.

lbs. Tighten the stabilizing bolts on the outside of the side frame to 300 ft. lbs.

5. If blade gap adjustment is required for the center of the shear, use the stiffener adjustment

bolts located at the rear of the stiffener.

6. To close the gap in the center of the shear, loosen one inside bolt and tighten the outside bolt.

When correct blade clearance is achieved, tighten the counter locking bolts securely. Recheck

blade gap before cycling the shear.

NOTE: When rotating the blades, clean and lightly oil blade and seat before

installing blade. Tighten blade bolts firmly. Set clearance adjustment to maximum

before overlapping, blades: Follow procedure in section 5.1. When grinding blades,

grind top and bottom of blade only. Shim lower blade, flush with bed top surface.

Clean and lightly oil blade and seat. Tighten blade bolts firmly; again, set clearance

to maximum before adjusting to avoid damage to blades; proceed as directed in

section 5.1.

Piranha ¼-12 Operators/Owner’s Manual

6. Maintenance Procedures

BEFORE MAINTAINING OR REPAIRING THE SHEAR, READ AND UNDERSTAND

THE CURRENT ANSI B11.4 STANDARD.

This section describes the procedures and requirements for maintaining and repairing the major

components of the Piranha 1/4-12 Shear.

6.1. Maintenance Schedule

This section outlines the suggested points and intervals for regular scheduled maintenance.

The hydraulic power unit is very sensitive to dirt and other contaminants, but will provide

many years of reliable service with a minimum amount of service. The operating temperature

and the cleanliness of the oil directly effect the life of the hydraulic oil. Regular oil and filter

changes will keep the system clean and free of sticking and clogged valves. Because

hydraulic cylinders are lubricated with every stroke, keeping them clean and free of scratches

and dings that may damage the cylinder rod seals is most important.

The Piranha 1/4-12 Shear is shipped with an extra hydraulic oil filter. It is important that after

the first forty hours of operation the oil filter be replaced. Upon using the included extra oil

filter it is suggested that a replacement filter be ordered for the next scheduled filter change.

See parts list for correct filter part number.

1. After First 40 hours:

• Change hydraulic filter

• Check fluid level

• Check gib clearances

• Grease ram slides

• Check fittings, bolts, nuts for tightness

2. Every 40 hours (weekly) thereafter:

• Grease ram slides.

• Check fittings, bolts, nuts for tightness

3. Every 3 months:

• Change hydraulic filter

The hydraulic filter element should be changed every 3 months depending on

workload and environmental conditions. See repair parts section for re-ordering

instructions and part numbers.

• Check hydraulic fluid level

• Check machine level & gib clearances

4. Every Year:

• Grease electric motor

• Check machine level

5. Every Two (2) years:

• Change hydraulic fluid

Piranha ¼-12 Operators/Owner’s Manual

6.2. Hydraulic Power Unit

The hydraulic power unit is a sophisticated and complex system. Only trained personnel

should attempt to perform adjustment procedures on the unit. The power unit generates very

high pressures. Never check for leaks using hands.

Before servicing the hydraulic system, block the ram and turn power off.

6.2.1. Oil Filter Replacement

Verify the exact element number prior to ordering the replacement element.

Photo Sensor An electronic sensor that uses light

wavelengths to detect the position or

presence of an object.

Point of Operation The location in the shear where the material

or a workpiece is positioned and work is

performed.

Pressure Reducer Typically, a hydraulic component that senses

secondary pressure to maintain that output

pressure regardless of the incoming

pressure.

Pressure Relief Typically, a hydraulic component that uses a

spring to hold an orifice closed until system

pressure overcomes the spring and allows

flow to the reservoir.
