Description

Stamping die

Technical Field

The utility model relates to a stamping die field especially relates to a stamping die.

Background

The punch press is a stamping type press. The pressing head of the punch press is provided with an upper die, and the pedestal of the punch press is provided with a lower die so as to press various stamping parts. The stamping production is mainly directed to plates. Through the mould, can make blanking, punch a hole, shaping, deep-drawing, trimming, essence towards, the plastic, riveting and extruded article etc. wide application in each field.

When small parts are pressed, the upper pressing die and the lower pressing die are replaced by clamping by an air pressure clamp, or are directly fixed on a punching machine by screws; the air pressure clamp is generally used for large moulds, is not suitable for clamping small moulds, is directly fixed by screws, frequently takes the screws, the screws fall carelessly, and potential safety hazards can appear when the screws fall into a punch press.

SUMMERY OF THE UTILITY MODEL

Not enough to exist among the prior art, the utility model provides a stamping die, it has solved the problem of the not adaptation of middle-size and small-size stamping die assembly punch press of prior art.

According to the embodiment of the utility model, a stamping die comprises an upper pressing die, a lower pressing die, a connecting ring and an expansion device, wherein the connecting ring is fixedly arranged at the upper part of the upper pressing die, four first threaded holes are uniformly opened around the connecting ring, and first locking screws are arranged on the first threaded holes; the expansion device comprises two connecting plates, two abutting plates and four second locking screws, wherein each connecting plate is provided with two second threaded holes, each abutting plate is provided with two positioning grooves, and the second locking screws penetrate through the second threaded holes and abut against the positioning grooves; the two connecting plates are fixedly arranged at the lower part of the lower pressing die in parallel; the two abutting plates are positioned on the outer sides of the two connecting plates.

The technical principle of the utility model is that: the integrated connecting ring and the expansion device are added to the upper pressing die and the lower pressing die respectively, the pressing die can be installed on the pressing head of the punch press by screwing the first locking screw on the connecting ring, and the lower pressing die can be installed on the pedestal of the punch press by screwing the second locking screw.

Contrast prior art, the utility model discloses following beneficial effect has: the integrated connecting ring and the expansion device can not cause the loss of the locking screw, and the die is convenient to operate and stable to install when being clamped.
