Description of Sheet Metal processing process
The sheet metal processing process mainly includes CNC programming blanking, bending, pressure riveting, welding, spraying, packaging and other processes.
CNC programming blanking
Sheet Metal Parts choose different blanking methods according to different requirements, including Laser Cutting cutting, CNC plasma cutting cutting, shearing machine blanking and other different ways. Now with the wide application of laser technology, sheet metal processing currently mainstream Laser Cutting Machine blanking, which has the advantages of fast cutting speed, low cost, fast programming, easy cutting of special-shaped parts, and no secondary processing. Laser Cutting Machine can be divided into 3015, 4020, 6020, etc. according to the cutting format, and there are also special cutting formats, such as 4015, 6025, 8025, etc.; According to the laser power, it can be divided into 500W, 1000W, 2000W, 4000W, 6000W, and now the highest is 15000W. Cutting power can be cut thickness, plate is also different, for the machine tool protective cover, gz mainly uses 1000~2000W laser cutting machine, which can not only ensure efficiency, but also improve quality.
CNC bending
In general, the bending in sheet metal processing of machine tools needs to keep the thickness of the middle of the bottom of the material unchanged, and the fillet gradually thinner, at this time the position near the flange will become thicker. And bending is the transition link from 2D flat parts to 3D parts, specifically with the help of bending machine to apply a certain pressure to the metal sheet, so that it is converted from elastic deformation into plastic deformation, at this time the sheet metal will first bend freely, and then under the action of pressure, the bending force arm, radius of curvature will continue to become smaller until the formation of V-shaped bending, of which the folding machine mold, folding bed is the main tool, and the thickness of the plate, bending direction, size, angle, etc. are strictly controlled.
GZ has a professional bending team, and there are professional Armada CNC bending machines and Yawei CNC bending machines to ensure that the innovative shapes we design can be perfectly realized.
Welding spraying
After completing the blanking, bending and other processing links, the parts should be welded to improve the strength of the parts, common welding methods are a little welding, CO2 gas shielded welding, etc., but to strictly control the welding deformation, and for machine tool protective covers, laser protective covers and other products, should fully consider their electrode materials, weld requirements, workpiece thickness, etc., and select the appropriate welding power source and current, so as not to affect the quality and efficiency of product welding. On this basis, sheet metal forming can be completed by surface processing, among which baking paint, electrogalvanizing, electrostatic adsorption, etc. are common surface treatment methods.
In the machine tool sheet metal mainly use spraying process for surface treatment, due to the country's attention to environmental protection, pickling, phosphating and other traditional processes have not adapted to the country's development needs, GZ has canceled pickling phosphating treatment, directly replaced with galvanized sheet, from the raw material to solve the pollution link, in welding also use galvanized sheet of special welding wire, to ensure welding quality.
Installation packaging
Installation is to follow certain requirements and methods, a number of components or parts combined together, so that it becomes a material whole, because it is the last process of sheet metal processing, if it is damaged and cannot be used, can only be reworked, so should do a good job of material protection
Because machine tool sheet metal has the characteristics of many types, many special-shaped parts, and a small number of single sets, there is a special set of production control processes for such products, from order picking to warehousing and warehousing, to ensure that the materials are complete.
