Hangzhou sheet metal processing factory
In all kinds of sheet metal parts processing has its own unique advantages, especially for complex shape or sheet metal parts processing can automatically complete the parts processing. According to the requirements of the drawing, the hole of different size and shape requirements can be processed automatically, or the hole and profile of larger shape can be produced and processed by small punching die with small step. In addition to the simple structure of the die for the existence of special processing technology of sheet metal parts, such as: shallow drawing, flanging hole can also be processed. Compared with the traditional stamping, die is more simple, the processing range, significantly improve the processing ability, for mass production and is particularly suitable for various forms of product processing, for the processing enterprises to keep up with the pace of market development, meet the demand of the product is very good, but because of the reduction in cost of various aspects, to effectively improve the economic benefits of enterprises.
Side wall wrinkles: the main reason for the wrinkles on the side wall of the parts is that the thickness of the material is not enough (relatively small allowable thickness is also thin) or eccentric when the upper and lower die is installed, resulting in large clearance on one side and small clearance on the other side, preventing measures to immediately replace the material and re-adjust the mold.
Hangzhou sheet metal processing factory, under normal circumstances, sheet metal parts have obvious strength, weight and cost advantages, at the same time, compared with the traditional parts have better point-to-point performance, so, up to now, sheet metal parts have been gradually used in China's electronics, communications and other high-tech fields.
Secondly, due to the modeling constraints caused by material processing properties, designers generally apply the following methods in the appearance design of industrial sheet metal equipment. Mondrian cutting technique, which is widely used in design. This asks stylist to need certain ability on plane composition. Second, the lamination method, in the lamination method we're going to use a combination of mondrian's method. Through the treatment of lamination, the product looks breathable and three-dimensional. Third, the bevel cutting and splicing method, which takes the potential through the bevel cutting of the face, often makes the product appear exaggerated characteristics.
Welding has argon arc welding, spot welding, etc., spot welding should first consider the position of the workpiece welding, in the mass production consider doing tooling to ensure that the spot welding position is accurate. For welding firmly on to the welding workpiece convex point, can make the convex point contact with the plate uniform before electric welding, to ensure the consistent of each point to heat, welding position can be determined at the same time, also, for welding, to adjusted the preloading time, the holding time, maintaining time and rest time, ensure the workpiece can spot welding is firm. After spot welding, welding scars will appear on the surface of the workpiece, which shall be processed by a flat grinding machine. Argon arc welding is mainly used for the processing of edges and corners of a workpiece to achieve the flatness and smoothness of the surface of the workpiece when the two workpiece are larger and connected together. The heat generated by argon arc welding is easy to deform the workpiece. After welding, it should be processed by sander and mill, especially the edges and corners.
According to the different stamping, there are two methods: cold stamping (explanation: pressure on the plate or hot Material) and hot stamping。 Different stamping methods should be selected according to the strength, plasticity, thickness, degree of deformation and equipment capacity of Material, and the original heat treatment state and use of Material should also be considered。
Hangzhou sheet metal processing factory flame cutting as the beginning of the traditional cutting method because of its low, in the past, the processing quality requirements are not high, the request is too high and then add a machining process can be handled, the market possession is very large. Today it is mainly used to cut steel plates over 40mm thick. Its defects are too large thermal deformation cutting, too wide slit, waste of information, and processing speed is too slow, only suitable for rough processing.
