Problems solved by technology

Due to technical reasons, the casting process technology is difficult to achieve the precision required by the technology, and it is easy to cause industrial pollution and waste
However, in the mechanical processing after casting, the accuracy of the processed products will be offset due to the accuracy of the mechanical equipment and the professional technical level of the employees. It is difficult to guarantee the accuracy and quality of the products, which will reduce the pass rate. At the same time, it also causes a lot of processing waste

Embodiment

[0021] Make iron lock body or copper lock body.

[0022] 1. Take iron ore powder or copper ore powder for oxygen exhaust, annealing and magnetic separation.

[0023] 2. Ingredients according to the alloy ratio (see the table below): Table 1

[0024] 3. Put the well-proportioned materials into the cavity of the lock body mold made according to the design requirements, and then install the mold on the press, which can be a punch press, hydraulic press, etc.

[0025] 4. Start the press, and extrude the material with a good ratio in the mold cavity (see Table 1) into a blank under high pressure, see figure 2 , are the two half-side embryos of the matching lock body.

[0026] 5. Then, the two halves of the iron lock body or copper lock body extruded into the blank form in step 4) are matched to form a whole lock body, and put into a high-temperature furnace for heat preservation and sintering (see Table 1). After sintering and solidification, finished product, see figure 1 sho...

Abstract

The invention relates to a process of preparing lock, comprising following steps: discharging oxygen, annealing and magnetic cobbing metallic powdered ore, matching alloy, fitting with presser and mold, extruding matched material to blank, putting blank into high temperature furnace for sintering, hardening and getting product. The process changes current preparing type, increases production efficiency, improves handling accuracy and quality, and greatly saves material and energy.

Description

technical field [0001] The lock body processing technology of the present invention relates to the technical field of lock manufacturing, and can manufacture padlocks and other special-shaped locks, especially locks whose main body material is metal. Background technique [0002] In the current lock making process, the main part of the lock is cast, and then rough machining and finishing are carried out to complete the lock body processing process. Due to technical reasons, the casting process technology is difficult to achieve the precision required by the technology, and it is easy to cause industrial pollution and waste. However, in the mechanical processing after casting, the accuracy of the processed products will be offset due to the accuracy of the mechanical equipment and the professional technical level of the employees. It is difficult to guarantee the accuracy and quality of the products, which will reduce the pass rate. Also cause a lot of processing waste simul...
