Processing process for single handle

Abstract

The invention discloses a processing process for a single handle. The processing process comprises the following steps of: producing a counterweight part through a counterweight part mould, mixing white electric oil and water in a proportion of 1 to 4 to obtain a mixed solution, soaking the counterweight part into the mixed solution for 15 minutes, taking out the counterweight part and putting the counterweight part onto a screen to dry in air until the surface of the counterweight part is dried; mounting a plastic inner sleeve mould onto injection molding machine equipment and embedding a copper nut into the plastic inner sleeve mould; pressing and assembling the counterweight part and the plastic inner sleeve mould through a pneumatic press and a positioning part under pressure of 6-8 kg to form an assembly part; mounting an injection mould on the injection molding machine, grabbing the assembly part through a mechanical hand and embedding the assembly part into the injection mould to perform injection molding, and automatically opening the mould after injection molding; and checking injected-molded blank, electroplating the blank which is checked to be qualified, and packaging the blank with pearl wool or a foam bag and putting the packaged blank into a dustproof box. The overall appearance of the product is injection molded by the mould, and polishing processing is not needed before electroplating, so that processing materials are saved, processes are simple, and production cost is reduced.

Description

technical field [0001] The invention relates to the technical field of hardware processing, in particular to a processing technology of a single handle. Background technique [0002] General metal handles are all solidly cast with alloys of zinc, copper, aluminum and other metals. The casting process has the following defects: [0003] 1. The handle after die-casting must be machined with screw holes, the process is complex, consumes more alloy materials, and the cost is higher, and the overall casting process may make the material of each part of the handle not uniform. [0004] 2. The appearance of the handle after die-casting needs to go through multiple polishing processes before it can be electroplated. During the polishing process, a large amount of dust will be generated, which will cause great harm to the surrounding environment and human health. [0005] 3. In addition, in order to reduce production costs, various manufacturers use low-quality alloys to produce han...

Problems solved by technology

[0003] 1. The handle after die-casting must be machined with screw holes. The process is complex, consumes more alloy materials, and the cost is higher. Moreover, the overall casting process may make the material of each part of the handle not uniform.

[0004] 2. The appearance of the handle after die-casting needs to go through multiple polishing processes before it can be electroplated. During the polishing process, a large amount of dust will be generated, which will cause great harm to the surrounding environment and human health.

[0005] 3. In addition, in order to reduce production costs, various manufacturers use low-quality alloys to produce handles. After polishing, the handles are also very rough, and the electroplating grade is also very low, which makes a large number of single handles low in quality, extremely short in service life, and prone to blistering on the surface. , which further affects the quality of the complete set of products of the assembler
