1. Precision principle: The number of processes for drawing parts is related to the material properties, drawing height, number of drawing steps, drawing diameter, material thickness and other conditions, and…
1. The accuracy of the feeding device itself. The backlash of gears driving the feeding roller is relatively small, and the servo motor driving the feeding roller can accelerate and…
Surface pretreatment: Clean the surface of the aluminum profile shell by chemical or physical methods to expose the pure matrix to facilitate obtaining a complete and dense artificial oxide film.…
The overall model of the blanking die structure design needs to describe all the parts involved in the die, and at the same time expand the confidence and craftsmanship contained…
Optimize the small holes of the product and reduce the types. The diameter of the punch ⑩ D ≥ 2.5T is appropriate (T = material thickness); Change from the conventional…
First wipe the surface of the outer cover with a clean gauze, and then polish with oilstone (20×20×100mm or larger), and polish with relatively small oilstone for arcs and hard-to-reach…
Commonly used process tests similar to the stamping process, such as drawing performance test, bulging performance test, etc., test the stamping performance of the material, in order to ensure the…
1. The processing of Metal Stamping parts should be conducive to the use of existing equipment, process equipment and process flow as much as possible to process them. Hager stamping:…
stamping refers to a production technology that uses a mold to apply an external force to the plate in the mold on a press to deform the plate to obtain…
Inspection method: visual inspection, whetstone polishing Inspection standards: Type A defect: It is worn through and is clearly visible on the outer surface, which is immediately visible to all customers.…
