1, stainless steel, mainly without any surface treatment, high cost.
2, hot-rolled plate SHCC, material T or more 3.0mm, is also used electroplating, baking paint parts, low cost, but difficult to shape, mainly using flat parts.
3, galvanized sheet SECC, SGCC. SECC electrolysis plate is divided into N material and P material. N material is mainly used for surface treatment and high cost. P material is used for spraying parts.
4, copper; mainly conductive parts, the surface treatment is nickel plated, chrome plated or not processed, and the cost is high.
5, aluminum sheet; commonly used surface chromate (J11-A), Suzhou laser sheet metal processing oxidation (conductive oxidation, chemical oxidation), high cost, silver plated, nickel plated.
6, aluminum profile, complex cross-section material, used in a variety of boxes. The surface is treated with the same aluminum plate.
7, cold rolled plate SPCC, mainly using electroplating and baking paint parts, low cost, easy to shape, material thickness less than 3.2mm. General sheet metal processing bending plate 90 degrees are required in the V planing trough through pressure to achieve, so they are the relationship between the tooling tool between V molding groove processing can also be said to be a process of sheet metal processing, some sheet metal products (thick thick) after bending the outer R angle is too large, Suzhou sheet metal processing so the V shape at the bend Slot (forthcoming thick planing), V type planer has two functions: one is to reduce the corner of the bending garden, the bending angle of the general sheet metal is equal to the thickness of the plate. If the bending angle of the workpiece is less than the thickness of the plate, the V groove should be planed; and the bending force of the Suzhou sheet metal processing plant is reduced, and the bending force of the workpiece can not be bent when the bending force is greater than the tonnage of the bending machine. At the time, the V groove can be planed to reduce the bending force.
1. Blanking: there are various ways of cutting materials, mainly in the following ways.
(1), punching machine: it is a kind of shape material which can be blanked out by one or more steps on the plate. The advantages of this kind of material are short time, high efficiency, high precision and low cost. It is suitable for mass production, but it is necessary to design a mold.
2. Scissors: it is a simple material for cutting the strip by cutting the cutting bed. It is mainly prepared for the die blanking forming. The cost is low and the precision is less than 0.2.
(3) laser cutting is used to cut the structure of the flat plate on a large plate by laser cutting. It is required to write a laser program like the NC material. It can lower the complex shape of the plate, with high cost and 0.1 precision.
(4), NC numerical control blanking, NC is the first to write the numerical control process program, using programming software, the drawing of the expansion map is written into the NC number drawing machine tool can be identified, so that the program according to these programs one step and one knife in Suzhou sheet metal blanking on the flat plate, but its structure is affected by the tool structure. This is low, and the precision is 0.15.
5. Sawing machine: mainly use lower aluminum profile, square tube, picture tube, round bar material and so on, with low cost and low precision.
In the processing of a large number of sheet metal devices, the assembly of the sheet metal cabinet appears very important, and its production process is very strict. The packing container of the outbound goods is required to do the performance test. The application form of the transportation package inspection for outbound goods and the inspection knots of the packaging containers of the production units are provided in the inspection of the outbound goods. The technical data on the sheet metal, packing container specifications, customer orders and packaging containers require the processing of sheet metal in Suzhou, the design process of the package container, the standard of material inspection and so on.
