Description

A side turning hole mechanism of a stamping die

technical field

The utility model relates to a body stamping die, in particular to a side turning hole mechanism of the stamping die.

Background technique

The hole turning mechanism of stamping dies for automobile body parts is usually vertical turning. For turning holes on inclined surfaces, the method of rotating parts is usually used to adjust the turning holes to the horizontal plane before turning the holes. When it is necessary to turn over the hole, the mold in the form of an up and down floating presser is usually used to turn over the hole, resulting in an increase in cost. And when the hole turning process is carried out, other process contents such as edge trimming and punching cannot generally be carried out.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is described in detail.

Referring to Fig. 1 and Fig. 2, the rollover hole mechanism of the stamping die shown includes an upper mold base 1 and a lower mold base 2, the upper mold base 1 is provided with a binder plate 10, and the lower mold base 2 is fixed with Place the lower die 17 of the parts. The upper mold base 1 is fixed with a first guide sleeve 15 for slidingly connecting the turning die 3, and the lower die base 2 is fixed with a second guide sleeve 16 for slidingly connecting the turning punch 4. 3 and the boring punch 4 are adapted to each other and coaxially arranged. Through the arrangement of the first guide sleeve 15 and the second guide sleeve 16, the accuracy of the movement directions of the hole turning die 3 and the hole turning punch 4 is ensured, and the accuracy of side turning holes is improved.

The lower surface of the upper mold base 1 is provided with a die wedge 5 inclined downward to the right, and the hole turning die 3 is arranged at the lower left of the die wedge 5 . The lower mold base 2 is provided with a chute, the chute is provided with a slide block 6 for reciprocating motion, the slide block 6 is provided with a punch wedge 7 inclined to the right and down, and the hole turning punch 4 is located on the Punch wedge 7 top right. Die return spring 8 is provided between the upper die base 1 and the hole-turning die 3 to provide power for the reset of the hole-turning die 3, and a punch return spring is provided between the lower die base 2 and the hole-turning punch 4 9. Provide power for the reset of the punch punch 4.

The slider 6 reciprocates in the chute through the driving wedge and the slider return spring 13, and the driving wedge includes the first wedge 11 which is arranged on the lower surface of the upper mold base 1 and is inclined to the left and downward and is arranged on the The second wedge 12 on the slider 6 and correspondingly matched with the first wedge, and the slider return spring 13 is fixed on the lower mold base 2 to provide a return force for the slider 6 .

An anti-collision block 14 is fixed on the lower mold base 2, and the anti-collision block 14 is matched with the left side of the slider 6 correspondingly. A limiting guide plate 18 is also fixed on the lower mold base 2 to provide guidance for the relative movement between the slider 6 and the chute. The setting of the anti-collision block 14 avoids direct contact with the chute side wall on the lower mold base 2 when the slide block 6 returns, causing damage to the mould. The setting of the limit guide plate 18 ensures the accuracy of the moving direction of the slider 6 .

When working, the die wedge 5 and the first wedge 11 move downward with the upper mold base 1. When it descends to a certain height, the binder plate 10 contacts the lower mold 17 to press the parts tightly, and then the upper mold base 1 Continue to move downward, the die wedge 5 is in contact with the punching die 3, drives the punching die 3 to slide axially, the first wedge 11 contacts the second wedge 12, and the slider 6 drives the wedge and Under the action of the limit guide plate 18, it moves to the right. When the slider moves to the right for a certain distance, the wedge 7 of the punch contacts with the hole-turning punch 4, and drives the hole-turning punch 4 to move in the axial direction. When the upper die base moves to the lowest point , the hole turning die 3 and the hole turning punch 5 cooperate to complete a side turning hole. Then the upper die base 1 moves upwards, the slider 6 returns to the left under the action of the slider return spring 13 and the limit guide plate 18, the hole turning die 3 returns axially under the action of the die return spring 8, and the hole turning punch 4 Return axially under the action of the return spring 9 of the punch. When the upper mold base moves up to a certain height, the binder plate 10 is separated from the lower mold 17, and all the moving mechanisms return to their initial positions until the upper mold base 1 When ascending to the highest point, a complete rollover action ends.
