Abstract
The utility model discloses an anti-rotation stamping die with a compression bar at an upper end. The anti-rotation stamping die with the compression bar at the upper end comprises a plunger chip and a lower die. The plunger chip is arranged above the lower die, a square stamping block is arranged at the lower end of the plunger chip, and the compression bar is fixedly installed at the upper end of the plunger chip. A protrusion block is arranged in the middle of the plunger chip. A spring is arranged on the plunger chip between the compression bar and the protrusion block in a sleeved mode. An upper die sliding sleeve is arranged outside the plunger chip in a sleeved mode. An anti-rotation pin is installed on the side wall of the upper die sliding sleeve, and is arranged on the plunger chip in a pressing mode. The compression bar exerts pressure on the plunger chip, and the plunger chip can return back due to the elasticity of the spring after stamping. The structure is reasonable, the anti-rotation pin is added, and therefore relative slip between the plunger chip and the upper die sliding sleeve can be prevented.
Description
Technical field
The utility model relates to the diel field, and a kind of upper end is with the Anti-rotation stamping die of depression bar specifically.
Background technology
Diel is in Cold Press Working, and a kind of special process that material (metal or nonmetal) is processed into part (or semi-finished product) is equipped, and is called cold punching die (being commonly called as cold-punching mould).Punching press is at room temperature, utilizes the mould that is installed on the forcing press that material is exerted pressure, and makes it produce separation or plastic deformation, thereby obtains a kind of pressure processing method of required part.
The utility model content
The purpose of this utility model provides a kind of upper end with the Anti-rotation stamping die of depression bar, and structure is more reasonable, has increased stop pin, can prevent the relative sliding between drift and the patrix sliding sleeve.
The technical solution of the utility model is as follows:
A kind of upper end is with the Anti-rotation stamping die of depression bar, include drift, counterdie, drift is positioned at the counterdie top, the lower end of drift has the square piece that rushes, the upper end of drift is installed with depression bar: the drift middle part is provided with projection, be set with spring on the drift between depression bar and the projection, drift is set with the patrix sliding sleeve outward; On the sidewall of patrix sliding sleeve stop pin is installed, stop pin is pressed on the drift.
The utility model has the advantage of:
Depression bar of the present utility model is exerted pressure to drift, and after punching press was finished, because the elastic force of spring, drift was realized return, and structure is more reasonable, and structure is more reasonable, has increased stop pin, can prevent the relative sliding between drift and the patrix sliding sleeve.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Referring to accompanying drawing, a kind of upper end is with the Anti-rotation stamping die of depression bar, include drift 1, counterdie 2, drift 1 is positioned at counterdie 2 tops, the lower end of drift 1 has the square piece 3 that rushes, the upper end of drift 1 is installed with depression bar 4: drift 1 middle part is provided with projection 5, is set with spring 6 on the drift 1 between depression bar 4 and the projection 5, the drift 1 outer patrix sliding sleeve 7 that is set with; Stop pin 8 is installed on the sidewall of patrix sliding sleeve 7, and stop pin 8 is pressed on the drift 1.
Claims (1)
