Sheet metal fabrication support
Technology NewsOne 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 one edge. The simplest way to make this object is usually to bend a flat object (i.e. a metal plate) at…
About stamping cost accounting
Technology NewsIs the steel plate width a fixed value? No, the width of the steel plate is affected by the size of the production line equipment. If the steel plate is inconsistent with the standard size, it needs special process treatment, which will cause the cost to rise; The equipment sizes of different manufacturers are different,…
About sealing strips contaminating sheet metal
Technology NewsTypes of sheet metal polluted by sealing strip: Chemical reaction pollution: the pollution caused by the migration of highly active additives (such as vulcanization accelerator, antioxidant, softener, etc.) in the rubber formulation system to the paint and their reaction with the paint. Generally, the stain is light yellow, which is a permanent change. Physical change…
Swing brazing and its advantages
Technology NewsThe beam forming and weld tracking functions are integrated into the same equipment through alo3. Filler wire can be used as a mechanical sensor. It is mainly used for laser welding of body in white, mainly including laser brazing of roof cover, trunk cover and automobile parts. The fluctuation of parts and the error of…
Painting and classification of finish paint
MFG NewsTopcoat spraying After finishing the spraying of intermediate primer and grinding and finishing, the topcoat can be sprayed. The gloss, brightness and good decoration of the coated surface are provided by the finish coat. The quality of the whole coating work is reflected by the finish coat. Therefore, the finish coat spraying is the most…
After bending, the end face of the workpiece bulges or is uneven
Technology NewsCause: when bending, the outer surface of the material is pulled in the circumferential direction to produce shrinkage deformation, and the inner surface is pressed in the circumferential direction to produce elongation deformation, so the bending end face bulges along the bending direction. terms of settlement: The punch and die shall have sufficient pressure at…
Determination of stamping die
Technology NewsThe so-called punching direction refers to the direction of the machine pressure on the blank during the die drawing process. Selecting the correct stamping direction is the first problem encountered in determining the drawing scheme. It not only determines whether a satisfactory process part can be drawn, but also affects the amount of process supplement…
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…
