Production equipment of thin-wall metal cylinder body

Abstract

The invention discloses production equipment of a thin-wall metal cylinder body. The equipment comprises a stand, and the stand is sequentially provided with a mandrel, a rotating and pressing part and a smoothing stamp die from one end to the other end, wherein the rotating and pressing part rotates around the mandrel, and the mandrel is in a slide match with the rotating and pressing part and the smoothing stamp die; the mandrel is internally provided with a loopback channel extending to a working end of the mandrel, and the loopback channel is connected with a cooling medium supply device; and the smoothing stamp die is internally provided with a heating element. After adopting the technical scheme, a thin-wall metal cylinder prefabricated product is firstly produced by utilizing rotating and pressing processing, and then through differential temperature drawing and smoothing, spiral fringes on the surface of the thin-wall metal cylinder are removed; meanwhile, the straightness and the wall thickness of the product can be renewedly revised; and in the differential temperature drawing and smoothing process, the mandrel is cooled, and the smoothing stamp die is heated, which can effectively suppress the martensite phase transformation caused by the smoothing and improve the plasticity of metal materials.

Description

Technical field: [0001] The invention relates to a production equipment of a thin-walled metal cylinder. Background technique: [0002] Generally, rolls for optical film production, nanoimprinting, large and small electronic imaging printers, and high-precision printing are made of polystyrene films and polyimide films with a wall thickness in the range of 0.03 to 0.3 mm. In addition, electroplating is performed in nickel plating, and nickel electroforming is used to extract an electroformed product in which nickel metal is deposited on a cylindrical matrix from the matrix. [0003] The rollers for the above applications are required to have good thermal conductivity and heat resistance because they are used in the process of continuous heating, pressing, cooling, peeling, etc., and because they are used as rotating bodies, they also need excellent fatigue resistance. Strength, rigidity. [0004] However, if resin materials such as polystyrene and polyimide are used as the...

AI Technical Summary

Problems solved by technology

However, this processing method still has obvious shortcomings. The thin-walled metal cylinder produced by spinning will produce a large number of spiral stripes on its surface, which seriously affects the surface flatness of the thin-walled metal cylinder. of products do not meet the extremely high surface flatness requirements of printing equipment

Moreover, for cylindrical bodies with a processing thickness of less than 0.1mm, the straightness of the processed product is poor and the wall thickness is uneven.
