Knowledge of sheet metal processing introduced
Basic knowledge of sheet metal processing.
I. Selection of materials. Generally used in sheet metal processing materials cold rolled (SPCC), galvanized steel (SECC), stainless steel, copper, aluminum, aluminum, etc. The role of the different As for how to use , which normally takes up to consider its purpose and cost.
1 cold-rolled plate, referred to as SPCC, is used for surface treatment of zinc plating or paint colorful pieces to use.
(2) galvanized sheet, referred to as SECC, paint pieces for the surface treatment is used in no special request, generally used in SPCC, can reduce costs.
3 copper generally used nickel or chrome plated parts used, sometimes without treatment. According to customer requirements.
4 aluminum. Chromate treatment is generally used for surface or oxidation conditions used.
5 stainless steel. Sub-mirror stainless steel and satin stainless steel, it does not need any treatment.
6 aluminum. Chromate treatment is generally used for surface or oxidation conditions used, mainly to play a supportive role or connection, a large number for a variety of plug box.
Two. Sheet metal machining process for any sheet metal, it has a certain process, which is the so-called process. With the sheet metal structures, processes may vary, but generally does not exceed the following a few points.
1 sheet metal parts design and part of its plans, with drawings of their way to the structure of sheet metal parts express. That is, a complex structure of the parts to start as a flat piece.
(2) cutting, mainly in the following ways:
a. Scissors under the bed material. Is to start map using shears cut out the shape of the length and width dimensions. If punching, cutting angle, and sub-punch combination of die punching, cutting angle shape.
b. Punch cutting. Is the use of punch, one or more sub-steps will be part of the plate after the commencement of the flat piece structure made of red shape its cost advantage is the short working hours, high efficiency, reduce processing costs, often used in mass production.
c. NC-cutting. NC cutting of the first to write NC programs. Is to use programming software, the expansion plan will be drawn into the preparation of the NC machine tool can identify the program. Let According to these procedures step by step in an iron on the flat parts of the structure of its shape punched out.
d. Laser cutting. Is the use of laser-cut, in a flat piece of iron will of its structure and shape cut out.
3 punch processing. Usually punch a punching process of cutting angle, blanking punch, punch the convex hull, red tear, pumping holes, such as processing methods, in order to achieve the purpose of processing its processing requires a corresponding mold to complete the operation. convex hull of a red convex hull mold, red tears are tears forming molds.
4 bending. Bending is the 2D flat pieces, folded into 3D parts. Its processing requires folding bed and the corresponding bending mold to complete the operation. It also has some bending sequence, the principle is the next knife does not produce interference in the first fold, after the fold will produce interference.
5 Welding Welding is welding together multiple components to achieve the purpose of processing a single part or welded seams to increase its strength. The processing side generally have the following: CO2 gas shielded arc welding, arc welding, spot welding, robot welding, etc. The choice of welding method is based on actual requirements and the material may be generally speaking CO2 gas shielded welding class for iron welding; TIG welding for aluminum class; main welding robot materials and parts in larger and longer weld used, such as cabinet type welding, robotic welding can be used, can save a lot of tasks, improve efficiency and welding quality.
6 Surface treatment Surface treatment generally phosphate coating, zinc plating colorful, chromate, paint, oxide, etc. are generally used for coating phosphated cold-rolled plate and electrolytic plate type, and its role mainly in the materials and parts table coated with a layer of protective film to prevent oxidation; again that it can enhance the adhesion of the paint. colorful zinc plated cold rolled steel for general use type surface treatment; chromate, aluminum and aluminum oxide type generally used for surface treatment; The specific choice of surface treatment is based on the customer's request.
7 assembled so-called assembly of multiple parts or components is a certain way according to group up together, making it a complete feed products. One should pay attention to is the protection of materials and parts, can not draw bumps. Assembled product is expected to complete a final step, if the materials and parts can not be used for planning bumps, to be rectified redo, will waste a lot of processing time, increase the cost of material goods, so pay special attention to the protection of materials and parts.
