WAMP power unit. Tooling. Air tank. CLINCHLOK BASICS: Clinchlok principle Punch adjustment.
  • Page 4 SAFETY INSTRUCTIONS OPERATOR SAFETY NOTICE: THE SURE-LOK IS DESIGNED AS A SAFE AND RELIABLE MACHINE. HOWEVER, AS WITH ANY PUNCHING MACHINE, THE CRITICAL DANGER AREA IS THE PINCH POINT BETWEEN THE PUNCH AND DIE. KEEP FINGERS AND LIMBS AWAY FROM THIS CRITICAL PINCH POINT. NEVER OPERATE THIS MACHINE WITHOUT ALL COVERS AND GUARDS IN PLACE.
  • Page 5 NORLOK MD SURELOK 24 FEATURES The SURE-LOK 24 features a one piece steel "C" frame with an 24" throat and integrated clinch-lok type tooling. The machine is specifically designed to fasten two ply material together, as used in the sheet metal and manufacturing industry.

  • Page 10 UNCRATING: Remove the machine from the shipping crate. It may be picked up with a chain hoist from either the 2" diameter hole in the top of the frames or by attaching a 3/4" NC eye bolt to the top of the "C" frame. DO NOT LIFT BY THE STAND! Locate the following items that will have been packed separately;...
  • Page 11 INSTALLING AIR SUPPLY: Make sure that the foot pedal is not activated. Make sure that the main air supply valve is turned OFF. Make sure that the tank drain valve is CLOSED. Supply the air tank inlet with 125 psi (max) - 80 psi (min). of clean dry air. Use a filter / regulator on the inlet line if necessary.
  • Page 12 OPERATION BASICS: FRAME: The SURE-LOK is designed around a very rigid flame cut steel "C" frame. The upper tooling barrel is welded pinned to the frame. The lower arm is bolted and pinned to the frame, this lower arm may be replaced for a different design if required.
  • Page 13 TOOLING: The clinching punch and stripper are located in the upper tooling and operate through the stroke of the machine (Usually 1” or ½”). The punch may be easily adjusted, through an inspection plate in the front of the barrel, to suit different material thickness.
  • Page 14 CLINCHLOK BASICS: CLINCHLOK PRINCIPLE. CLAMPS DRAWS LOCKS The clinchlok joint is formed when the upper tooling squeezes two layers of material between the punch and die. The amount of squeeze is very important to the strength of the clinchlok joint and to the life expectancy of the punch and die.
  • Page 15 PUNCH ADJUSTMENT: The amount of joint squeeze is controlled by adjusting the punch either towards the punch or away from the punch with the punch adjusting screw. For thin material the die will have to be lowered (moved towards the die) and for thick material the punch will have to be raised (moved away from the die).
  • Page 16 DIE SELECTION: There are three sizes of dies required to cover the complete range of material that the SURE-LOK can fasten. As a general rule the punch in the upper tooling does not need to change when different material is joined. The die selection chart can be used to find which die will be most suitable for your application, however the chart is a guide only, different types of material may require a different size of die.
  • Page 17 JOINT STRENGTH: PULL PEEL There are two ways to measure the strength of a Clinchlok joint, pull and peel (see diagram). Pull is almost always stronger than peel and is less sensitive to die adjustment. Typical joint strengths for properly adjusted tooling are given for commercial quality mild steel.
  • Page 18 JOINT FAILURE If pulled hard enough any clinchlok joint will pull apart. There are two usual ways for a clinchlok to pull apart; NON TEARING FAILURE The two halves of the joint will pull apart leaving a male joint half (punch side) and a female joint half (die side).

  • Page 20 TESTING JOINT STRENGTH: The best method of testing joint strength is to pull the joint apart in both pull and peel and measure the force required with a pull tester. In production however an indication of the joint strength can be found by measuring the diameter of the button cap (the "mushroom") on the die side of the joint.
  • Page 21 PUNCH ADJUSTMENT PRINCIPLE The punch must be adjusted to produce the correct amount of "squeeze" between the punch and die when the joint is made. As described earlier, the correct punch adjustment is very important for producing a good joint and to maximize punch and die life. The aim of punch adjustment is to produce minimum "squeeze"...
  • Page 22 OBSERVE ALL SAFETY PRECAUTIONS, AND MAKE SURE ALL GUARDS AND COVER PLATES ARE IN PLACE. Make a sample clinch joint using the correct material. The joint should be too weak because the punch will be too high (not enough "squeeze"). Turn the punch adjuster screw clockwise (towards the “L”) 1/6th turn, lowering the punch.
  • Page 23 SURELOK MANUAL 2002...
  • Page 24 SETTING LASER: WARNING!! ALTHOUGH THIS LASER IS A VERY LOW POWER DEVICE AND CANNOT BURN, IT COULD CAUSE EYE DAMAGE WITH PROLONGED DIRECT EYE EXPOSURE. NEVER LOOK DIRECTLY INTO THE LASER OR POINT IT AT ANYONE. The SURE-LOK can be fitted with a laser guide to help locate the center of the joint. The laser bracket is mounted as shown on the right side of the "C"...
  • Page 25 OPEN HEIGHT ADJUSTMENT: The stroke of the SURE-LOK is factory set at 1" (or optional ½”). This will give a maximum open height - (the gap between the punch and the die), of 1" or ½”. This gap may be easily reduced, to eliminate a "pinch point" by adjusting a screw in the center of the top of the WAMP power unit as shown in the drawing below.
  • Page 26 MAINTENANCE DAILY: MAKE SURE ALL GUARDS AND SAFETY EQUIPMENT ARE IN PLACE. Drain moisture from air tank. Check and clean air filters. Maintain correct inlet air pressure. Check and maintain correct air regulator pressure. Check automatic return and adjust if necessary. Clean and oil die.
  • Page 27 (see drawing next page) MAINTENANCE - REPLACING DIE REMOVE THE AIR SUPPLY TO THE PRESS AND DRAIN ALL THE AIR FROM THE AIR TANK. Loosen the die securing screw. Remove the die by pulling out of the die plate. Clean and oil the new die and install into the die plate. The new die should sit flush with the top of the die plate.

  • Page 31 MAINTENANCE - AUTO RETURN ADJUSTMENT The press features an automatic - one shot return system. The automatic return valve is a time delay system mounted on the side of the operator valve assembly. The return valve is adjusted by turning a screw mounted on the top of the valve. Turning the screw clockwise (in) will increase the return delay (slow the press down).
  • Page 32 MAINTENANCE - PRESSURE ADJUSTMENTS Supply the machine with 125 PSI (max) 80 PSI (min) clean dry air. We recommend a 1/2" (min) air line at 120 psi. The inlet pressure regulator must be set as follows; Medium Duty tooling 100 PSI. Light Duty tooling 80 PSI.
  • Page 33 MAINTENANCE - LUBRICATION OF UPPER TOOLING The upper tooling should be greased with lithium EP general-purpose grease whenever the punch is changed or at least every six months. It is not necessary to remove the upper tooling to grease the internal components. They can be greased from the outside of the machine through a grease hole in the barrel.
