Hangzhou Sheet Metal Processing Factory
It has its own unique advantages in the processing of various sheet metal parts, especially for complex shape or thin plate parts, which can automatically complete the processing of parts. According to the requirements of drawings, holes with different sizes and shapes can be automatically processed, and holes with larger shapes and contours can also be produced by small punching dies with small steps. The die with simple structure can also process sheet metal parts with special processing technology, such as shallow drawing, flanging hole, etc. Compared with the traditional stamping, the die is simpler, the processing range is wider, and the processing ability is significantly improved. It is especially suitable for mass production or product processing with various forms. It is very advantageous for the processing enterprises to follow the development pace of the market and meet the product demand. Moreover, because of the reduction of various costs, it makes the enterprises. The economic benefits have been effectively improved.
8. Side wall wrinkles: The main reason for the wrinkles on the side wall of the part is that the thickness of the material is not enough (the allowable thickness is small) or the eccentricity of the upper and lower dies occurs when they are installed, resulting in large clearance on one side and small clearance on the other side. The preventive measures are to replace the material immediately and to readjust the dies.
Hangzhou sheet metal processing factories usually have obvious advantages in strength, weight and cost, and have better point-to-point performance than traditional parts. So far, sheet metal parts have been gradually applied in high-tech fields such as electronics and communications in China.
Secondly, due to the shape constraints caused by material processing attributes, in the process of industrial sheet metal equipment appearance design, designers generally use the following methods. Mondrian cutting technique, which is widely used in design. This requires designers to have certain skills in graphic composition. Secondly, the lamination method, when we use the lamination method, we should use it in accordance with the Mondrian method. The product looks breathable and three-dimensional through laminated processing. Thirdly, inclined cutting and splicing technique, which takes the potential through the oblique cutting of the straight plane, often makes the product appear exaggerated features.
There are argon arc welding, spot welding, etc. Spot welding should first consider the position of the workpiece welding, and in mass production, consider the tooling to ensure that the spot welding position is accurate. In order to solder firmly, the bump on the workpiece to be welded can make the bump contact with the flat plate uniformly before electrified welding, so as to ensure the consistency of heating at all points, and can also determine the welding position. Similarly, to carry out welding, it is necessary to adjust the pre-pressing time, the holding time, the holding time, the resting time to ensure that the workpiece is available. Firm by spot welding. After spot welding, there will be weld scars on the surface of the workpiece, which need to be treated by a flat grinder. Argon arc welding is mainly used when two workpieces are larger, but also when they are joined together, or when the edges and corners of one workpiece are processed, so that the surface of the workpiece can be smooth and smooth. The heat generated during argon arc welding can easily deform the workpiece. After welding, the workpiece should be treated by a grinder and a flat grinder, especially in the aspect of edges and corners.
According to the different stamping, there are two methods: cold stamping and hot stamping. Different stamping methods should be selected according to Material's strength, plasticity, thickness, deformation degree and equipment capability. Material's original heat treatment state and use should also be considered.
Hangzhou sheet metal processing factory flame cutting as the initial traditional cutting method, because of its low demand for processing quality in the past is not high, when the request is too high, plus a processing process can be processed, the market holds a large amount. Today it is mainly used to cut over 40 mm thick steel plate. Its defect is that the thermal deformation is too big, the cutting seam is too wide, the data is wasted, and the processing speed is too slow, only suitable for rough processing.
