Metal Rack for home Metal Frame manufacturing Process explanation: Although the glasses are small, seemingly simple, but its production process and other products, there are a series of complex manufacturing processes and production technology requirements, including industrial drawing, mold manufacturing, stamping molding, industrial cleaning, gong-cut welding, surface treatment, electroplating, spraying, Metal Rack for home assembly, packaging, as well as casting plastic molding, dyeing and a series of complex manufacturing processes. According to statistics, the production of a finished glass frame requires at least 250 procedures, the following sections are introduced: The first step in the production of glasses is to draw drawings, three views and accessories drawings, the three views are to be distributed to the production line above the use, the requirements of the spare parts map more accurate, Metal Rack for home will directly affect the precision of the glasses frame Chengdu. Metal Rack for home Drawing drawings This is the foundation, very important
Yi Production Molding
1. Circle: With the formed special coil material, after the opening material, round the circle process produced, the picture frame has two kinds of production process for the automatic computer winding machine, a kind of coil to open the material and then around the circle, Metal Rack for home after the circle and then pressure radian.
2. Stamping Products: glasses production of spare parts mainly to stamping. such as the nose, foot, eyebrows, feet, and so on, the main manufacturing process is as follows: open material → wire (mainly feet) → oil pressure (embossed pattern/letter, etc.) → flying Edge → bending → heavy roll → throw Huang wire Introduction: Rotary wire is a certain diameter and length of the round wire, with a cold drawing machine (commonly known as The Wire machine) to the different diameter and length set by the N section, and has a certain taper requirements of the products. Metal Rack for home The main purpose of this paper is to make the production of the part foot wire conveniently and easily, and greatly reduce the process difficulty of the production of the foot silk.
Second, welding process 1. Part processes are mainly open material, circle, milling nose, milling head radian, cut false line, bending, punching/pressure radian and so on.
2. Cleaning process using pickling, Metal Rack for home hot-dip ultrasonic removal of oil decontamination
3. Common whole frame spot welding process: weld mortar → frame (point transverse denier) → weld glass → open mortar → welding foot wire/bag foot → play screws → grinding Zhuang tou → milling pit/milling silver sheet push plate Spring foot: cut false line → welding push plate shell → spring core → hook → play screws/front Hinge → play 7 ° bend → front hinge plus welding → cut → push plate polishing → clean → milling head radian → annealing → Bent zhuang
4. Welding equipment resistance Butt welding machine, high-frequency induction welder, argon pressure welding machine. III. Surface treatment Process
1. polishing, barrel process Huanglashi open surface → welding point → cleaning → tightening screws → inspection → coarse sand barrel → fine sand barrel → out of the bucket sand → Bai polishing → Test
2. Electroplating process Cleaning (hot-dip ultrasonic wax removal, electric discharge oil, neutral activation) → pre-plating to the bottom → electric color → spray add glue
3. Point Paint/Baofa process
