Technical solution is used by the utility model solves its technical problem：One kind is used to eliminate the clear angle of relay yoke The undesirable stamping die of bending, it is characterised in that：Mould is pushed away including upper die and lower die, the first punching module, the second punching module and side Block, by the fastening of upper die and lower die, it is right successively that there is the upper mold the first punching module, the second punching module and side to push away module Relay yoke is bent, and the molding dog-ear of the first punching module is 95 °~105 °, second punching module Molding secondary dog-ear is 90 °, and it is 88 ° that the side, which pushes away the molding dog-ear three times of module,.

Include beating bar, drive block and sliding block as a preferred embodiment, the side pushes away module, the bar of beating is under the driving of upper mold It is vertically moving, and the drive block is pressed down on, the drive block is coordinated by a lozenges and the sliding block, and with The bar pushing side of beating pushes away the sliding block, and sliding block is made to be processed the relay yoke.

As a preferred embodiment, further including sliding block cushion block, the bottom surface of the sliding block is slidably matched with the sliding block cushion block.

As a preferred embodiment, first punching module include can fasten and coordinate mutually the first punch-pin and the first cavity plate, First punch-pin under the drive of the upper mold with the first cavity plate fasten and coordinate, and to relay yoke punch process shape Into a dog-ear.

As a preferred embodiment, the end of first punch-pin has arc lead angle, the inside triangular angular of the arc lead angle Match with a dog-ear.

As a preferred embodiment, second punching module include can fasten and coordinate mutually the second punch-pin and the second cavity plate, Second punch-pin under the drive of the upper mold with the second cavity plate fasten and coordinate, and to relay yoke punch process shape Into secondary dog-ear.

As a preferred embodiment, the end of second punch-pin has arc lead angle, level off on the inside of the arc lead angle vertical Directly.

The beneficial effects of the utility model are：

1st, by changing a dog-ear so that when the secondary dog-ear of machine-shaping and three times dog-ear, the side-thrust needed reduces, Eliminate due to side-thrust it is excessive caused by workpiece displacement and the problems such as clear angle bending is bad, drum material.

2nd, the end of the first punch-pin and the second punch-pin is respectively provided with arc lead angle so that the first punch-pin, the second punch-pin with work When part contacts, bending angle gradually increases, and prevents from causing bending bad due to stress mutation.

The utility model is described in further detail with reference to the accompanying drawings and embodiments；But a kind of use of the utility model Embodiment is not limited in eliminating the clear undesirable stamping die of angle bending of relay yoke.
