JIATONG PRECISION SHEET METAL

  The weight of sheet metal processing parts is relatively light, but the strength is high and the conductivity is good. The important thing is that the cost is relatively low. If a large number of large-scale production has good performance, processing can improve the function and service life of products. Of course, we all know that processing skills are indeed a little troublesome, but the processing of sheet metal chassis shell can bring greater benefits to enterprises, so there are so many reasons for selective processing. After the drawing is completed, different blanking methods are selected according to different expansion diagrams and batches. Welding includes argon arc welding, spot welding, carbon dioxide maintenance welding, manual arc welding, etc. For spot welding, the welding direction of the workpiece and the manufacturing of the locator should be considered first, so as to ensure the accuracy of spot welding positioning in mass production. 3. When bending, objects ...

The production process of the processing industry of sheet metal chassis and cabinets has developed rapidly. In the welding operation of chassis and cabinets, there are mostly strict welding requirements, such as welding slag, deformation, burn through, bulge and depression are not allowed. The welding requirements are neat, uniform, firm and reliable. With the popularization of laser cutting machine, the accuracy of sheet metal cutting and blanking is getting higher and higher, which also creates conditions for the application of laser welding machine technology. Many sheet metal processing enterprises began to consider using laser welding machine technology to improve welding accuracy and aesthetics. Welding advantages of laser welding machine: 1. Real time control and various waveform settings bring good welding quality; 2. It can weld at room temperature or under special conditions, and the welding equipment is simple; 3. CCD coaxial monitoring system is configured, and image segme...

  Generally, sheet metal parts have obvious advantages in strength, weight and cost, and have better point-to-point performance than traditional parts. Therefore, up to now, sheet metal parts have been gradually applied in China’s high-tech fields such as electronics and communication. At the same time, people have gradually put forward higher requirements for the quality and function of sheet metal parts, The proper optimization of the original sheet metal processing technology has become the focus of sheet metal processing personnel. According to the actual research, this paper believes that the optimization of processing technology should be carried out one by one from the application of four basic cold processing links of sheet metal processing. 1  Blanking    First of all, as far as the blanking link is concerned, generally speaking, blanking refers to the separation of sheet metal materials through the stamping of the die, so as to realize the separation of she...

  1 Water Cooling Block Many techniques can be used to control the welding deformation of special welding workpieces. For example, in thin plate welding, the use of water-cooled blocks can take away the heat of the welded workpiece. The copper pipe is welded to the copper fixture by brazing or tin welding, and the circulating cooling is carried out through the water pipe to reduce the welding deformation. 2 Wedge Block Locating Plate “Locating plate” is an effective technology to control welding deformation during butt welding of steel plate, as shown in the figure. One end of the positioning plate is welded on a plate of the workpiece, and the other end wedges the wedge block into the pressing plate. Multiple positioning plates can even be arranged to maintain the positioning and fixation of the welded steel plate during welding. 3 Thermal Stress Relief Except for special cases, it is not a correct method to eliminate stress by heating. Welding deformation shall be prevented or re...

  Engineers and designers must ensure that the CAD system they purchase is compatible with the current program. If not, they may start from scratch. The initial requirement is to determine the sheet metal compatibility in the CAD setup you plan to purchase. However, no single CAD system can meet all your design needs, which is the fact that all of us must accept. In addition, some of the most advanced CAD systems available today may not be compatible with your current tools. Now there are more available CAD modeling platforms with sheet metal design functions, which can be easily used to develop 3D models. In addition, there are various CAD systems that can convert solid models into sheet metal elements, and then supplement plane patterns from them.    CAD system with manufacturability function design will improve productivity and minimize waste of time. It is strongly recommended to use DFM function in sheet metal product design, because this system can ensure the operab...

  One of the simplest and most cost-effective methods of manufacturing brackets, especially simple brackets such as corner brackets, is sheet metal manufacturing. The bracket is usually composed of two or more planes connected along an edge. The easiest way to make this object is usually to bend a flat object (i.e. a metal plate) at two or more positions: the simplest example is to add a flat rectangle bent at 90 ° to form a straight contour, and turn it into a bracket with an L-shaped contour.     Most scaffolds are functional, and their purpose is to connect and support objects. However, brackets can also be decorative: since brackets are usually visible (e.g. mounted on shelves above the eyes), they may have a decorative and gorgeous feel, ranging from complex machined decorative features to gold plating.

In order to ensure the material utilization rate and the minimum number of die changes in bending, the thickness specifications of plates on the same structure shall not exceed three at most. For structures with high strength requirements, the method of pressing reinforcement on thin plates can be adopted; It should be avoided that the unfolding size of parts is equal to the outline size of raw materials: the shape of plates supplied in the market is not square. If the unfolding size is equal to or very close to the outline, there is no allowance for the whole square, and the product size after direct processing has errors, which will affect the installation and use. For non-sprayed plates with decorative surface requirements, the decorative surface and grain direction shall be considered in combination with the plate materials. For any purpose, the plate with decorative surface shall be used and the grain direction shall be required. For non-exposed parts, the processing process shall...
