Method and device for machining saddle-type lining part

Abstract

The invention discloses a method and a device for machining a saddle-type lining part. According to the method and the device, a metal plate is used as the raw material, a blank which is bent into a cylindrical shape is sleeved on a saddle-type molding die core which is composed of a left die core and a right die core, subsequently the saddle-type molding die core on which the blank is sleeved is fed and put into a molding groove of a lower die of a saddle-type molding die, and an upper die is closed up, so that the blank of the cylindrical shape can be pressed into the desired shape of the saddle-type lining part by compressing the upper die with the cooperation of the upper die, the lower die and the saddle-type molding die core. The method and the device not only have the advantages of less investment and low manufacturing cost, but also have the advantages of simple structure, convenience in operation, security, reliability and the like; by utilizing the method and the device, both the product quality can be ensured, and the production efficiency is improved, and moreover the method and the device are applicable to the production of saddle-type lining parts of various specifications, and are also applicable to demands of large-scale or small-scale production.

Description

technical field [0001] The invention relates to a processing method and device for saddle-shaped bush parts, belonging to the technical field of saddle-shaped bush parts processing. Background technique [0002] With the widespread use and rapid development of bushing parts, manufacturers have developed various styles of bushing parts. Such as Figure 6 The bushing part shown is a commonly used saddle-shaped bushing part. Its structure is saddle-shaped, and its two ends are in the shape of a bell mouth. The circumference is not closed, and there is an opening along the axial direction. At present, in the existing technology, the saddle-shaped bush parts are often processed by rolling the copper tube with special rolling equipment. The disadvantage of this production method of rolling with special rolling equipment is that The process is relatively complicated, the investment in equipment is large, and the production cost is high. It is only suitable for large batches and sm...

AI Technical Summary

Problems solved by technology

Due to the complex structure of the saddle bushing parts, especially the closing and flanging process is difficult to realize, and the parts require a flat and smooth surface without wrinkles, indentations and scratches, so the existing general equipment is used for Processing and production, the surface quality of its products is difficult to be guaranteed, so the existing processing methods for producing saddle-shaped bushing parts are not ideal
