GENERAL INFORMATION

Clamps for Hockey Pucks

These two types of clamps have a preloaded cup shaped springs system which guarantees the perpendicularity of the clamping force even without ball joints. A washer on the spring guide indicate the achievement of the right force. In order to have a correct mounting, the following is recommended:

Technical Characteristics

The bars of clamps type CO70, CO89 and CO102 are made of high resistant steel.
The cup shaped springs are made of steel UNI 50CrV4. Upon request they can be made of stainless steel.
The screws and bolts are made of steel class 8.8.
All metal parts are galvanicaly treated in order to be corrosion proof.

Insulator Properties

The insulators for the clamp are made of polyammide 6.6 with 50% glass fiber added. The have dielectric property of 85KV/mm. The thickness of the IB8 insulator is 1.7mm, the IB10 is 2.7mm working temperature of 105 C.

Clamping force conversion; 1 KN=225 LBS, 1 Kg=9.806N, 1 Kg=2.2 LBS.

Clamp Selection

The choice of the clamp suitable for each different application can be made
according to three main parameters:
a) Type of semiconductor (diameter and thickness)
b) Requested clamping force
c) Total thickness of heatsink

MOUNTING DIRECTIONS

MOUNTING INSTRUCTIONS FOR CLAMPS
TYPE C070-C089

These two types of clamps have a preloaded cup shaped springs system which guarantees the perpendicularity of the clamping force even without ball joints. A washer on the spring guide indicate the achievement of the right force.

In order to have a correct mounting, the following is recommended:

  1. The two contact surfaces of semiconductor should be covered with a thin coating of an approved joint compound and then the possible surplus should be removed.
  2. Locate the semiconductor on one of the two heatsinks centrally by using the provided pin after having checked the polarity. Then the semiconductor should be rotated to spread the compound.
  3. Position the second heatsink on the semiconductor and located it centrally by using a second pin. Then slightly rotate the heatsink to spread the compound.
  4. Mount the clamp on the heatsinks by tightening alternately the bolts with a wrench up to the contact with the metal washer of the insulator checking the alignment of heatsinks semiconductor.
  5. Tighten alternately both bolts each time about 1/6 turn until the indicating washer turns free, then tighten both bolts once more about 1/10 turn.

MOUNTING INSTRUCTIONS FOR CLAMPS TYPE C102

This type of clamp has a preloading system consisting of two sets of springs, a ball joint which assures the perpendicularity of the load force and two tangs which indicate the achievement of loading force. An advantage of this kind of clamp is the reduced overall size in comparison with the other with central spring bolts.

In order to have a correct mounting, the following is recommended:

  1. The two contact surfaces of semiconductor should be covered with a thin coating of an approved joint compound and any surplus should be removed.
  2. Locate the semiconductor on one of the two heatsinks centrally by using the provided pin. The semiconductor should be rotated to spread the compound.
  3. Position the second heatsink on the semiconductor locate it centrally by using a second pin. Then slightly rotate the heatsink to spread the compound.
  4. Tighten the two bolts on the short threaded side.
  5. Position the ball joint on the back of the heatsink by using the proper split dowel pin.
  6. Mount the clamp on heatsinks semiconductor set by tightening alternately the nuts on the bolts up to the contact with metal washers of the insulator, taking care that the bar is parallel to the heatsink and the heatsinks semiconductor set is aligned and parallel.
  7. Tighten alternately the nuts about 1/8 turn each until the indicating tanks are free.
  8. Tighten both nuts once more about 1/12 turn.

MOUNTING INSTRUCTIONS FOR CLAMPS TYPE C155

This type of clamp uses the elasticity of bar material. The indicator of the load force
is a tang which is fixed on one side and free on the other.
The perpendicularly of the load force is guaranteed by a proper floating joint.

In order to have a correct mounting, the following is recommended:

  1. The two contact surfaces of semiconductor should be covered with a thin coating of an approved joint compound and then any surplus should be removed.
  2. Locate the semiconductor on one of the two heatsinks centrally by using provided pin after having checked the polarity. Then the semiconductor should be rotated to spread the compound.
  3. Position the second heatsink on the semiconductor and locate it centrally by using a second pin. Then slightly rotate the heatsink to spread the compound.
  4. Position on the back of the heatsink the floating joint by using the proper split dowel pin.
  5. Mount the clamp on the heat sink semiconductor set using two wrenches to tighten the nuts on the screws up to the contact with the metal washers of the insulator, taking care that the above set is aligned and parallel.
  6. Tighten alternately the nuts about 1/6 turn each until the indicating tangs are free.
  7. Tighten both nuts once more about 1/12 turn.
  8. In care of disassembly of the clamp for a possible replacement of the semiconductor, before loosening the nuts, flex the tank slightly outward to the point that it gets free from the bar.
