1. The emergence of new sheet metal processing
Conventional sheet metal processing procedures are to select cutting, stamping, hemming, spot welding or flame cutting, hemming, and welding processes. It is obviously not suitable for orders of various types, small batches, customized, high-quality, and short delivery times. With the use of laser processing procedures, it will replace "cutting and stamping", with the characteristics of flexibility and high flexibility.
Therefore, when the new sheet metal machining procedures are laser processing, hemming, spot welding/riveting welding, in view of the high softness, high precision of laser processing, and the maturity and promotion of three-dimensional design technology, customers can re-design and re-design Profits from the process, and then achieve the standard to control costs and shorten the construction period.
2. Traditional sheet metal processing and new sheet metal processing
Now the sheet metal processing procedure is finished by laser cutting and hemming at one time; the purpose of reducing the procedure, shortening the construction period and controlling the cost has been achieved.
Under traditional sheet metal processing procedures, common clamps are provided for welding. Nowadays, the process of the components is similar to the carpenter tenon structure, the marking is accurate, the welding fixture is simple, and the product deformation is small.
Because of the application of the tenon structure, the spot welding process can be coordinated after the workpiece is folded, and all the steps can be carried out. The deformation of the workpiece is small, and there is no need to shape or polish before painting. Due to the characteristics of the new sheet metal processing technology, it has a good software supporting design for sheet metal processing equipment, laser cutting, and bending processing. It is suitable for the design of two-dimensional parts, the design of pipe parts, the design of hemming workpieces, the development of three-dimensional graphics, and the transmission of numerical control programs to the designated equipment according to the standardized computer network.
