Abstract

A kind of diel Re-stress structure is the utility model is related to, it is characterized in that:Including the destressing station being arranged at die feeding mouth, drift and cavity plate are set respectively in the upper and lower sides of destressing station, workpiece sets some salient points by passing through between drift and cavity plate, on the surface that the drift and cavity plate contact with workpiece respectively.Salient point mutual dislocation on salient point and cavity plate on the drift.The salient point combines arrangement by some point-like salient points, linear salient point and polyline shaped salient point and formed.Diel Re-stress structure described in the utility model, structure is reliable, can effectively reduce the influence of raw material internal stress, improves production efficiency and yield, can smoothly be produced in production, it is not necessary to frequently adjustment.

Description

Diel Re-stress structure
Technical field
A kind of Re-stress structure is the utility model is related to, especially a kind of diel Re-stress structure, belongs to punching Compression mould technical field.
Background technology
With economic development, the electric equipment products that people use in life are more and more, and the component in electrical equipment accordingly increases It is more, and ram frame is one of three big basic materials in appliance component, the metal material such as copper material that ram frame uses is It is process by rolloff, it is inconsistent due to the material bearing of trend in crushing process, and cause material internal internal stress not Unanimously, the stainless steel material of rolloff is especially not easy, internal stress difference is bigger, in the more product punch process of bending easily Cause product distortion, dimension overproof etc. bad, influence the yield and production efficiency of product.
Existing punching production is made a return journey de-stress using more flat machine, and because material internal stress is inconsistent, more flat machine is by list Limited to compared with flat structure, more flat effect is poor, and the frequently more flat machine of adjustment is needed in production, causes production efficiency to reduce, defective products increases It is more.
The content of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, there is provided a kind of diel Re-stress knot Structure, structure is reliable, can effectively reduce the influence of raw material internal stress, improves production efficiency and yield.
According to technical scheme provided by the utility model, the diel Re-stress structure, it is characterized in that:Including setting The destressing station being placed at die feeding mouth, drift and cavity plate are set respectively in the upper and lower sides of destressing station, workpiece is by rushing Pass through between head and cavity plate, some salient points are set on the surface that the drift and cavity plate contact with workpiece respectively.
Further, the salient point mutual dislocation on the salient point and cavity plate on the drift.
Further, the salient point combines arrangement by some point-like salient points, linear salient point and polyline shaped salient point and formed.
Of the present utility model to state diel Re-stress structure, structure is reliable, can effectively reduce raw material internal stress Influence, improve production efficiency and yield, can smoothly be produced in production, it is not necessary to frequently adjustment.
Brief description of the drawings
Fig. 1 is the schematic diagram of diel Re-stress structure described in the utility model.
Fig. 2 is Fig. 1 top view.
Description of reference numerals:1- drifts, 2- workpiece, 3- cavity plates, 4- salient points.
Embodiment
With reference to specific accompanying drawing, the utility model is described in further detail.
As shown in Figure 1 and Figure 2, diel Re-stress structure described in the utility model includes being arranged at die feeding mouth The destressing station at place, drift 1 and cavity plate 3 be set respectively in the upper and lower sides of destressing station, workpiece 2 by drift 1 and cavity plate 3 it Between pass through, on the surface that the drift 1 and cavity plate 3 contact with workpiece 2 respectively, some salient points 4 are set;The utility model passes through Salient point is set on drift 1 and cavity plate 3, so as to form application point in the stamping surface up and down of workpiece 2, these application points change Stress direction in workpiece material, microcosmic upper stress anisotropy, its stress are cancelled out each other, and show can on whole material Have the function that de-stress.
The salient point mutual dislocation on salient point and cavity plate 3 on the drift 1, the utility model pass through upper and lower drift and recessed Effective arrangement of the size of salient point and relative position on mould, salient point mutual dislocation is extruded workpiece, make workpiece material elastic deformation, Stress intensity is formed on microcosmic unanimously for material and anisotropy, is macroscopically reaching the purpose of stress removal.
The salient point 4 is combined by some point-like salient point not of uniform size, different, linear salient point and polyline shaped salient points Form, ensure the elastic deformation of workpiece material.
Operation principle of the present utility model is to make material by way of alternating bending deformation to change stress direction, is discharged Internal stress, ensure product size stability.
