Description

A kind of in-flanges frock

Technical field

The utility model relates to the frock that auto parts machinery is made, and is specifically related to a kind of in-flanges frock.

Background technology

In the manufacture process of auto-parts, part can need in-flanges as shown in Figure 1, can only be in the existing technology by some simple tools or the manual in-flanges that carries out, production efficiency is low, cause in batches the flange comparison difficulty of getting up, and accuracy is not enough, is easy to generate deviation, thereby make scrappage higher, increased the production cost of manufacturer.

Summary of the invention

Technical problem to be solved in the utility model is to provide a kind of in-flanges instrument, can make the efficient height of in-flanges, the accuracy height.

For solving above-mentioned prior art problems, the utility model adopts following scheme: a kind of in-flanges frock, comprise cope match-plate pattern, the lower bolster that is connected with cope match-plate pattern, be equipped with die shoe in the middle of the described lower bolster, described die shoe both sides respectively are equipped with a bracing frame, switching has a side direction flanging die that pivots on the support frame as described above on left and right directions, described side direction flanging die upper end is processed with lug boss in the inner part, be equipped with eccentric swage on the described cope match-plate pattern and can promote the fork cutter that the side direction flanging die overturns, be equipped with the positive flanging die corresponding on the described eccentric swage with lug boss.

As preferably, described side direction flanging die upper end is processed with the arcuation projection in the outer part, and described fork cutter lower end is equipped with the fork cutter in the inner part and inserts, and the described fork cutter lower end of inserting is processed with the targeting port corresponding with the arcuation projection in the inner part.The fork cutter is inserted and is used for improving the fork cutter life-span, and the fork cutter utilizes targeting port and cooperating of arcuation projection that the side direction flanging die is inwardly overturn when pressing down.

As preferably, be equipped with extension spring between in the outer part in the outer part and on the bracing frame on the described side direction flanging die.Utilize the extension spring elastic reset.

As preferably, lean on the outside of side direction flanging die to be equipped with limited block on the support frame as described above.Carry out spacing to the side direction flanging die.

As preferably, be equipped with the location-plate corresponding on the described die shoe with eccentric swage, be processed with the locating slot of location product spare on the described location-plate.

As preferably, be equipped with guide pillar on the described lower bolster, be equipped with the guide pin bushing corresponding on the described cope match-plate pattern with guide pillar.

As preferably, described cope match-plate pattern is equipped with the flange die shank.

Beneficial effect:

The utility model adopts technique scheme that a kind of in-flanges instrument is provided, in the process of in-flanges, utilize the side direction flanging die that is equipped with on the positive flanging die that is processed with on the cope match-plate pattern and the lower bolster that part is carried out in-flanges, can make the efficient height of in-flanges, the accuracy height.

The specific embodiment

As Fig. 2 and Fig. 3, a kind of in-flanges frock, comprise cope match-plate pattern 1, the lower bolster 2 that is connected with cope match-plate pattern 1, be equipped with die shoe 9 in the middle of the described lower bolster 2, described die shoe 9 both sides respectively are equipped with a bracing frame 3, switching has a side direction flanging die 4 that pivots on the support frame as described above 3 on left and right directions, described side direction flanging die 4 upper ends are processed with lug boss 41 in the inner part, be equipped with eccentric swage 5 on the described cope match-plate pattern 1 and can promote the fork cutter 6 of side direction flanging die 4 upsets, be equipped with the positive flanging die 51 corresponding on the described eccentric swage 5 with lug boss 41.Described side direction flanging die 4 upper ends are processed with arcuation projection 42 in the outer part, and described fork cutter 6 lower ends are equipped with the fork cutter in the inner part and insert 61, and described fork cutter 61 lower ends of inserting are processed with the targeting port 62 corresponding with arcuation projection 42 in the inner part.Be equipped with extension spring 7 between in the outer part in the outer part and on the bracing frame 3 on the described side direction flanging die 4.The outside by side direction flanging die 4 on the support frame as described above 3 is equipped with limited block 8.Be equipped with the location-plate 10 corresponding on the described die shoe 9, be processed with the locating slot 11 of location product spare on the described location-plate 10 with eccentric swage 5.Be equipped with guide pillar 12 on the described lower bolster 2, be equipped with the guide pin bushing 13 corresponding on the described cope match-plate pattern 1 with guide pillar 12.Be equipped with flange die shank 14 on the described cope match-plate pattern 1.

During practical operation, as Fig. 4 and Fig. 5, utilize flange die shank 14 that cope match-plate pattern 1 is pressed down, the fork cutter arcuation projection 42 of targeting port 62 squeeze side on flanging die 4 on 61 of inserting, make side direction flanging die 4 overturn to the inside, lug boss 41 on the side direction flanging die 4 passes the locating slot 11 on the location-plate 10, positive flanging die 51 is close on eccentric swage 5, the part of placing in the middle of the extruding that needs in-flanges, extension spring 7 this moment is stretched, the part in-flanges well after, will carry on the cope match-plate pattern 1, side direction flanging die 4 resets under the elastic recovery of extension spring 7.
