Embodiment Construction

[0028] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0029] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes ...

Abstract

The invention relates to a workpiece reshaping method which comprises the following steps of: measuring deformation amount of workpieces, and selecting a plurality of kinds of deformation amount of a larger number of workpieces; separately designing and manufacturing corresponding reshaping jigs according to the multiple kinds of deformation amount; putting the deformed workpieces into an ultraviolet-ray UV oven to rotate until a preset temperature condition; and reshaping the deformed workpieces through the reshaping jigs. Compared with the conventional reshaping method, a reshaping rebounding rate is reduced, the condition of appearing anode cracks after reshaping is improved, the yield of the workpieces is greatly increased, and assembly success and delivery speed are guaranteed.

Description

technical field [0001] The invention relates to the technical field of sheet metal parts processing technology, in particular to a workpiece shaping method. Background technique [0002] Workpiece deformation is divided into elastic deformation and plastic deformation, in which elastic deformation can be recovered, while plastic deformation cannot be recovered. In the processing technology of sheet metal parts, the desired result is plastic deformation, that is, the workpiece will not rebound after being shaped. [0003] Since sheet metal parts need to go through various stamping processes such as stamping, bending, and embossing before shaping, stress release during processing will cause deformation of the workpiece, which does not meet the requirements of the product, affecting the assembly and delivery speed of the product. In order to solve this problem, the workpiece will be shaped before assembly. The traditional shaping method uses jigs to shape, and the rebound rate...
