Laser welding technology
Technology NewsLaser welding can be divided into pulse welding and high-power continuous welding. Laser welding can make a single weld obtain high-density energy from the laser source. High-speed welding has little effect on the heating and deformation of the weld. The welded joint has high performance and quality, and the weld size of laser welding can…
History of explosive welding
Technology NewsExplosive welding was first put forward by Carl in 1944. He was the first to observe the solid-state welding of materials caused by explosive detonation under high-speed collision, so he put forward the idea of using explosion and ultrasonic technology to weld various metals together. Then philipchuk V of the United States introduced the explosive…
Difficulties in sheet metal stretch forming
Technology News1) In order to ensure the accuracy of the part surface, it is necessary to adopt deep drawing forming with many bulging components, so the thinning amount in the top area of the part arc is the largest, and the thickness thinning amount is easy to exceed the tolerance; 2) The springback after deep drawing…
Analysis of sheet metal stamping process
Technology NewsStamping plays a very important role in the mechanical processing industry. It is widely used in aerospace manufacturing, automobile panel manufacturing and other industries. The output value of stamping parts also accounts for a large proportion in the whole sheet metal processing industry. Taking aerospace and automobile panel parts as examples, this kind of sheet…
Reduce the deformation of sheet metal welding with the help of external force
MFG News1 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…
Several key technologies of CO2 laser cutting?
Technology NewsThe main related technologies are as follows One is the automatic focusing system technology. The smaller the focus depth is, the smaller the diameter of the laser direct focus is. Therefore, it is very important to control the position of the focus relative to the surface of the cut material. Second, cutting and perforation technology.…

Bending link
MFG NewsBending link usually refers to the process of preventing the sheet metal material on the bending equipment, causing the elastic deformation of the sheet metal material through the pressure of the upper die or the lower die, and plastic deformation according to the actual design scheme after the elastic deformation. In the application process of…
Sheet metal punching hole
MFG News1 .size of sheet metal blanking hole Generally speaking, the punching size of sheet metal is at least 1.5 times the thickness of sheet metal. Of course, the punching size is also related to the material. The minimum punching size of softer materials can be less than the thickness of the sheet metal, while the…
