A forming device and method for complex inner and outer wall cylindrical parts

Abstract

The invention discloses a forming device and method of a complex inner wall and outer wall cylindrical part. The forming device comprises a concave die separation mechanism, an inner and outer sectiondie separation mechanism and a cylindrical convex die mechanism. The concave die separation mechanism is composed of a multi-section concave die and concave die drive cylinders. The multi-section concave die is of a two-section or four-section vertical symmetric structure, a hydraulic cylinder is used for controlling so that automatic die combining and separation can be achieved, a die cavity inthe shape of the outer wall of the part is arranged in the multi-section concave die. The inner and outer section die separation mechanism is mainly composed of the hydraulic cylinder, inner and outercore shafts and inner and outer section dies, the outer edges of the inner and outer section dies coincide after die separation, and a mold chamber in the shape of the inner wall of the part is formed. The cylindrical convex die moves vertically through the drive cylinder to achieve one-time forming of the cylindrical part in the complex shape. According to the forming device and method, the problems existing to the manufacturing processes of traditional extrusion forming, casting, welding and the like when the part in the complex shape is formed are effectively solved, material consumption is low, cost is saved, and the forming device and method are suitable for large-batch production.

Description

technical field [0001] The invention relates to the technical field of moulds, in particular to a device for forming components with complex shapes on the inner and outer walls of a cylinder. Background technique [0002] Cylindrical parts are widely used in industrial production. The plastic processing technology of cylindrical parts has the advantages of low energy consumption, material saving and high efficiency, and has become an important means of cylindrical part processing. With the development of production and science and technology, many industrial sectors, especially national defense, aerospace, electronics and other industries require the shape and structure of products to be more and more complex, and the requirements for product performance are getting higher and higher. Using simple mechanical processing methods to process parts with complex shapes has high surface precision, but there are many production processes, low efficiency, serious waste of materials, ...

AI Technical Summary

Problems solved by technology

However, due to the characteristics of the extrusion forming method, for such complex-shaped cylindrical parts, it generally requires multiple processes to complete, which seriously affects the production efficiency; even if the one-time forming method is used, it is also faced with problems such as difficult demoulding after forming.
