Generally speaking, punching machines have punching machines for right angles, punching machines for dropouts, punching convex packages, laser cutting plants and other processing methods to achieve the processing purpose. Its processing must correspond to the mould shell to carry out the actual operation. Punching processing convex package has convex package mould, punching processing tearing has tear forming mould, etc.
Riveting. There are common riveted nuts, nuts, screws, etc. The riveting is usually achieved by riveting them to sheet metal parts according to a press or hydraulic machine riveting machine.
Sheet metal bending. Bending is the folding of a 2D flat sheet into a 3D object. Its processing must be carried out by a single folding bed with a relative bending die. It also has a certain bending sequence. The mechanism is to fold first without interfering with the next cut, sheet metal welding followed by folding and then interfering.
Welding. Welding is the welding of several parts together in order to achieve the purpose of processing, and its processing is generally shown below:CO2 gas shielded welding, argon arc welding machine, welding, intelligent robot welding, etc. The selection of this welding method lies in the specific provisions and raw materials. In general, stainless steel plates are welded using CO2 gas shielded welding. Argon arc welding machines are used for welding aluminium plates. Intelligent robot welding is suitable for large raw materials and long welding places.
Surface treatment. In general, the surface treatment contains phosphate treatment film, electroplating process colourful zinc, chromium trioxide, baking paint process, air oxidation, etc.. Phosphate treatment film is usually used for cold-rolled plate and electrolytic method of thick steel plate. Its primary function is to apply a protective film on top of the raw material to avoid air oxidation. Secondly, it improves the adhesion of the baking process. The electroplating process for multi-coloured zinc is generally used for cold rolled sheet finishes. Chrome trioxide and air oxidation are usually used for the surface treatment of aluminium sheets and aluminium alloy profiles. The choice of the actual surface treatment depends on the needs of the user.
Assembling. By assembling, we mean putting together several parts or components in a way that builds up a perfect raw material. One thing that should be noted is the maintenance of the raw material components, which must not be rubbed or scuffed.
