Embodiment Construction

[0019] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0020] Such as figure 1 As shown in , it is a schematic structural diagram of the guide nut teeth that need to be processed. At present, machining is mainly used for production, and errors are prone to occur after rotary processing. The present invention is produced by lost foam casting, which overcomes this shortcoming, see the following examples for details.

[0021] The guide nut tooth lost foam casting method is specifically carried out according to the following steps,

[0022] a, foaming, using expandable polystyrene resin with a relative density of 1.05 t...

Abstract

The invention relates to a guide nut tooth lost foam casting method, belongs to the technical field of lost foam casting, aims to solve the technical problems of large machining error and high production cost, and provides the guide nut tooth lost foam casting method which has the characteristics of adoption of lost foam casting, low production cost, high surface glossiness of a casting, accurate size and shape, simplified operation, negative pressure pouring and capability of improving the tissue density of the casting. The technical scheme adopted is performed according to the following steps: foaming; forming; clustering; performing model hanging coating; performing vibratory forming; casting; cooling and cleaning. The method is widely used for casting of guide nut teeth.

Description

technical field [0001] The invention relates to a lost foam casting method for guide nut teeth, which belongs to the technical field of lost foam casting. Background technique [0002] On the premise of meeting the design accuracy and technical requirements, reduce product costs, shorten the production cycle, break through the traditional cognition, and realize the improvement of casting forming technology. The traditional process is to use mechanical processing to make 60 teeth on the circumference, but due to technical and equipment reasons, the error of the last tooth is different when combined. In order to meet the design requirements, high-precision equipment must be invested in order to reduce the error between teeth. Greatly increased production costs. Contents of the invention [0003] In order to solve the technical problems of large processing errors and high production costs in the prior art, the present invention provides a method of using lost foam casting, w...
