Description

Punching die with punching waste not easy to splash

Technical Field

The utility model relates to a stamping die technical field, more specifically say, relate to a stamping die that waste material that punches a hole is difficult for splashing.

Background

The stamping die is a special process equipment for processing materials (metal or nonmetal) into parts (or semi-finished products) in cold stamping, and is called cold stamping die (commonly called cold stamping die). Stamping is a press working method in which a die mounted on a press is used to apply pressure to a material at room temperature to cause separation or plastic deformation of the material, thereby obtaining a desired part.

In the existing stamping die, the punching process is a common processing procedure, the punching process is a stamping procedure for separating waste materials from materials or working procedure pieces along a closed contour, required holes are obtained on the materials or the working procedure pieces, but when the existing structure drives a punch to complete the punching of a workpiece placed on a lower die and restore to the original position, the waste materials generated by the punching are easy to return along with the punch, and even possibly fly out of the punching holes, so that the next punching process is influenced.

SUMMERY OF THE UTILITY MODEL

1. Technical problem to be solved

To the problem that exists among the prior art, the utility model aims at providing a stamping die that waste material that punches a hole is difficult for splashing, it can realize the in-process that the drift resumes to the normal position after the work of punching a hole is accomplished, and the waste material is difficult for following outside the drift splashes out the punching press hole together, has reduced the trouble of artifical clearance.

2. Technical scheme

In order to solve the above problems, the utility model adopts the following technical proposal.

The utility model provides a punching die that waste material that punches a hole is difficult for splashing, includes mould and bed die, it is located the top of bed die to go up the mould, it is connected with evenly distributed's drift to go up the mould bottom, lower mould upper end is dug there are a plurality of punching holes, the drift matches with the punching hole, a plurality of location archs of drift bottom fixedly connected with, and is a plurality of location arch is cyclic annular even distribution in the drift bottom, punching hole inner wall is dug there is the mounting hole, fixedly connected with backup pad between the two inner walls about the mounting hole, the backup pad surface is dug there are a plurality of trapezoidal holes, location arch and trapezoidal hole phase-match can realize the in-process that the work of punching a hole was accomplished the back drift and resume to the normal position, outside the waste material was difficult for following the drift and has been splashed out the punching hole together.

Further, the mounting hole inner wall rotates and is connected with a plurality of stoppers, and is a plurality of the stopper is annular spaced distribution at the mounting hole inner wall, the stopper is located the upside of backup pad, and when the drift moved down and punched a hole to the work piece, when the drift drove the waste material to move and pass trapezoidal hole after, the drift upwards resumes the in-process of normal position, and the setting of stopper can further restrict bouncing of waste material, makes the waste material be difficult for following the drift and outside the punching press pop-up hole.

Further, a plurality of rubber cushion blocks are fixedly connected to the inner wall of the mounting hole, the rubber cushion blocks are located between the limiting blocks and the supporting plate, the rubber cushion blocks correspond to the limiting blocks, one ends, far away from the mounting hole, of the rubber cushion blocks are in contact with the limiting blocks, the limiting blocks are extruded when the punch drives the waste materials to move downwards, the limiting blocks rotate towards the direction close to the inner wall of the mounting hole, the limiting blocks after rotation can restore to the original positions due to the arrangement of the rubber cushion blocks, and the waste materials are limited.

Furthermore, a plurality of the ring-shaped structure central points surrounded by the limiting blocks and a plurality of positioning bulges are positioned on the same vertical plane, when waste materials clamped into the trapezoidal holes are bounced carelessly, the bulges formed by the positioning bulges on the waste materials cannot be bounced continuously due to the limiting effect of the limiting blocks.

Furthermore, an included angle formed between the limiting block and the rubber cushion block is an acute angle which is 30-60 degrees, so that the limiting block can limit the waste materials forming the protrusions, and the upward moving process of the punch is not easily influenced.

Furthermore, protruding trapezoidal structure for under the narrow width of a jacket, the mounting hole is under the narrow width of a jacket column structure, when making the drift punch a hole to the work piece, makes the work piece waste material have the arch of matcing with the location arch equally because of the bellied setting in location, and then makes the work piece waste material can match with trapezoidal hole and be difficult for following the drift and pop out.
