Abstract
The utility model relates to a stress relief hole of metal stamping parts, which has a stamped area. The utility model is characterized in that: a plurality of the stress relief holes are provided in the circumference of the stamped area in the interlaced arrangement. The utility model has the advantages of springback and deformation phenomena reduction of the metal stamping parts, effective residual stress relief and qualification rate guarantee of the stamping parts molding, with the stress relief holes equipped in the circumference of the stamped area of the stamping parts.
Description
(1) technical field
The utility model relates to a kind of stress relief hole of metallic stamping pieces.
(2) background technology
As everyone knows, in the processing technology of large thin-wall metallic stamping pieces, the resilience of forming part is the key factor that influences product quality, in the middle of processing for the computer cabinet shell of mainly finishing with shearing, bending, punching group technology, there is such problem equally, how to reduce effectively and avoid resilience, become an important research project.
(3) summary of the invention
The purpose of this utility model is to provide a kind of stress relief hole of metallic stamping pieces, can effectively reduce, discharge the central residual stress of thin-wall metal spare moulding, avoid resilience, the distortion of large-scale metallic stamping pieces, reduce the fraction defective of part, improve the quality of metal cabinet.
In order to achieve the above object, the utility model provides a kind of stress relief hole of metallic stamping pieces, and this metallic stamping pieces has the district that is stamped, and it is characterized in that: this stress relief hole has most, and is to be located at this district's periphery that is stamped to be distributed in distance.
The stress relief hole of described metallic stamping pieces is characterized in that: this stress relief hole can be elongated hole, and this district that is stamped is centered on.
The utility model is after the district's periphery that is stamped of this metallic stamping pieces is provided with stress relief hole, and resilience, the metaboly of this metallic stamping pieces significantly reduce, and can discharge residual stress effectively, have guaranteed the qualification rate of metallic stamping pieces moulding.
(4) description of drawings
Fig. 1 is a structural representation of the present utility model.
(5) specific embodiment
With reference to Fig. 1, the stress relief hole of metallic stamping pieces of the present utility model, this metallic stamping pieces 1 is the loam cake of a horizontal host computer case, and this metallic stamping pieces 1 has a recessed district 2 that is stamped, and it is characterized in that: be provided with most spaced stress relief holes 3 in these district's 2 peripheries that are stamped.This stress relief hole 3 can be elongated hole and this district 2 that is stamped is centered on.Stress relief hole 3 is set can discharge residual stress effectively, has guaranteed metallic stamping pieces 1 stamping forming qualification rate.
Claims (2)
