The auxiliary device for inserting the pin into the radiating fin can be used for simply and rapidly performing punch riveting for combining the radiating fin with the pin, production efficiency is improved, processing cost is reduced, and fine processing quality can be obtained.

Description

Fin is inserted the PIN servicing unit

Technical field

The utility model is about a kind of servicing unit, refers to a kind of slotting PIN servicing unit of fin that is mounted on the stamping machine especially.

Background technology

Along with scientific and technological industry develops fast; Electronic component is more and more faster on computing is carried out, and the heat that is produced during its running is also more and more high, for this heat effectively being left; Operate under permissive temperature to keep electronic component, usually fin can be set on electronic component.

Now in the fin production industry; The combination of PIN on the fin; Be earlier PIN to be put into the preset groove of fin, again fin placed on the mould, utilize manual type PIN to be pushed to the precalculated position with instrument; Make PIN stretch out one section, carry out the punch riveting action again in the fin outside.But, this kind processing mode, not only process velocity is slow, and production efficiency is low, and is prone to accurately not put in place because of human factor causes PIN, and causes the product fraction defective to improve.

The utility model content

The utility model is to the existing shortcoming of combination PIN processing mode on the above-mentioned fin, and the fin of proposition the utility model is inserted the PIN servicing unit.

The utility model provides a kind of fin to insert the PIN servicing unit; It comprises: a holder, a pneumatic cylinder, a slide block and at least one bar that pushes, and wherein this holder is mounted on the stamping machine front side, and this pneumatic cylinder is installed on this holder; This pneumatic cylinder has a piston rod and stretches out this holder outside; This slide block sliding sleeve is on the outward extending two-parallel axis post in this stamping machine front side, and this slide block is connected with the piston rod of this pneumatic cylinder, and past polyslip before and after can being driven by the piston rod of this pneumatic cylinder; This pushes bar and is incorporated on this slide block and stretches out, and can be with this slider displacement.

As preferably, the said bar that pushes is through in the two correcting holes of stamping machine counterdie front side guiding block.

Compared with prior art, the beneficial effect that the fin of the utility model is inserted the PIN servicing unit is, when the slotting PIN servicing unit of said fin carries out combining the operations of PIN on the fin; The piston rod that can operate pneumatic cylinder promotes slide block, and what make that group is established on the slide block pushes bar and will put into the PIN of fin groove in advance and push to the precalculated position, carries out the punch riveting action; It is fast to reach process velocity; Production efficiency improves, and can guarantee that the PIN position is accurate, reduces the product fraction defective.

The specific embodiment

The preferred embodiment that following conjunction with figs. is inserted the PIN servicing unit to the fin of the utility model is elaborated:

The fin of inserting perspective view and Fig. 2 the utility model of PIN servicing unit like the fin of Fig. 1 the utility model is inserted shown in the side view of PIN servicing unit; It is to be mounted on stamping machine 2 front sides that the fin of the utility model is inserted PIN servicing unit 1; It includes: a holder 11, a pneumatic cylinder 12, a slide block 13 and the push rod 14 that balances or cancel each other; Wherein said holder 11 is mounted on stamping machine 2 front sides; Said pneumatic cylinder 12 is installed on the holder 11; This pneumatic cylinder 12 has a piston rod 121 and stretches out holder 11 outsides, and said slide block 13 movable sliding sleeves are on the outward extending two-parallel axis post 21 in stamping machine 2 front sides, and this slide block 13 is connected with piston rod 121 front ends of pneumatic cylinder 12; And can drive these slide block 13 front and back toward polyslip by the piston rod 121 of pneumatic cylinder 12; The said push rod 14 that balances or cancel each other is incorporated into to stretch out on the slide block 13 and is through in the two correcting holes 231 of stamping machine 2 counterdies 22 front side guiding blocks 23, and this stamping machine 2 is provided with the patrix 24 corresponding with counterdie 22 in addition, and is provided with two locating pieces 25 at counterdie 22 rear sides.

When carrying out the operations of fin 3 combination PIN4,, earlier PIN4 is put into two grooves 31 that fin 3 is preset like Fig. 3 and shown in Figure 4; And this fin 3 placed location on the counterdie 22 of stamping machine 2, as shown in Figure 5 again, the piston rod 121 of the pneumatic cylinder 12 of operation assisting device 1 makes it promote slide block 13 displacements; The push rod 14 that balances or cancel each other that drive is mounted on the slide block 13 advances, and utilizes these push rod 14 that balances or cancel each other two correcting holes 231 through guiding block 23 that PIN4 is pushed to the precalculated position along the groove 31 of fin 3, makes PIN4 stretch out one section in fin 3 outsides; Receive two locating pieces, 25 blocks location; Then as shown in Figure 6, the patrix 24 of stamping machine 2 carries out the punch riveting action downwards, and it is fixing that PIN4 is combined with fin 3; And it is as shown in Figure 7; Return original position by the piston rod 121 drive slide blocks 13 of pneumatic cylinder 12 and the push rod 14 that balances or cancel each other, then can take out finished product as shown in Figure 8, accomplish processing action.

Moreover the above-mentioned quantity that pushes bar 14 also can be one or more.

In sum, the fin that the utility model provided is inserted the PIN servicing unit, when it can combine the operations of PIN4 on carrying out fin 3; Advance by the pneumatic cylinder 12 drive slide blocks 13 and the push rod 14 that balances or cancel each other; And the PIN4 that will put into fin 3 grooves in advance by this push rod 14 that balances or cancel each other pushes to the precalculated position, and it is fast to reach process velocity, and production efficiency improves; And can guarantee that the PIN position is accurate, reduce the product fraction defective.
