Medical sheet metal processing is the key technology that sheet metal technicians need to master, and it is also an important process of sheet metal product forming. Medical sheet metal processing includes traditional cutting, blanking, bending, stamping methods and process parameters, as well as a variety of cold stamping die structures, the working principles and operating methods of various equipment, new stamping processes and technologies. Medical sheet metal processing is called sheet metal processing. So, what are the technical characteristics of medical sheet metal processing?

1 High power density: the workpiece absorbs the temperature that rises rapidly after sheet metal processing and melts or vaporizes, even high melting point, high hardness, high brittleness materials (such as ceramics, diamond, etc.), can also be processed with sheet metal;

2. Medical sheet metal processing beam is easy to control: easy to combine with precision machinery, precision measurement technology and electronic computers to achieve high automation and high processing accuracy;

3. Convenient and flexible: the robot can process sheet metal in harsh environments or places that are difficult for others to enter, and most welding medical sheet metal processing accuracy is low, so the amount of deformation and correction is large.

4. Wide application range: beam divergence Angle can be less than 1 milliradian, spot diameter can be as small as microns, action time can be as short as nanoseconds, picoseconds. At the same time, the continuous output power of high-power sheet metal processing can reach the order of kilowatts to ten kilowatts.

5. In the assembly process, in order to ensure product quality, it is often necessary to carry out multiple selection, adjustment, measurement and inspection.

Cold working Sheet metal processing refers to the blanking and cutting around raw materials such as sheets, profiles and pipes. The processing of forming, connecting and other processes has its own processing characteristics and characteristics. Therefore, it has formed its own unique processing work content, production technology and operating specifications. Because there are many welding methods used in industrial production, it can be divided into three categories according to the characteristics of welding technology.

1. Fusion welding: It is characterized by heating the joint of the weldment to a molten state through local heating, fusing with each other, and then combining with each other after condensation. Common arc welding and gas welding belong to this category.

2. Pressure welding: The common feature is that regardless of whether the welding is heated, a certain pressure is applied when welding, so that the two bonding surfaces are in close contact, promoting the nodule effect between the atoms, so that the two weldparts are firmly connected. Resistance welding and friction welding belong to this category.

3. Brazing: similar to fusion welding, it can also obtain a strong connection, but the two have essential differences. In this formula, the solder with a melting point lower than the solder is heated together with the solder to melt, but the solder itself does not melt. The liquid solder wets the weldment, fills the joint gap, diffuses with the weldment, achieves bonding with the solid welding metal, and connects to each other after condensation. Such as brazing, brazing, etc.
