Specific embodiment
Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings, it should be understood that preferred reality described herein
Apply example only for the purpose of illustrating and explaining the present invention and is not intended to limit the present invention.
As shown in Figure 1, a kind of automobile metal plate work processing method of the present invention, comprising the following steps:
The first step, it is smooth, the plate of sheet metal component is subjected to preliminary treatment first, so that the plate of sheet metal component becomes smooth, i.e., will
Single sheet metal component is placed between two smooth piece, by shortening the distance between smooth piece, so that the surface of sheet metal component is uniform
Contacted with smooth piece so that sheet metal component becomes smooth, sheet metal component is avoided to occur to bend deformation, shadow during transportation
Ring subsequent production, smooth extruding when a length of 1h to 4h between, and two smooth piece of surface temperature needs to be maintained at 30 DEG C and arrives
Between 90 DEG C；
Second step, cutting, the part bent to sheet metal component is cut, in order to avoid sheet metal component bending place after bending
Accumulation, which occurs, first to be cut, and cutting process uses cutter or laser cutting, preferential to select laser cutting, metal plate after cutting
Golden part carries out natural cooling, and cooling time is between 1h to 4h；
Third step, it is first to form, the sheet metal component after cooling good and cutting is placed at the beginning of carrying out sheet metal component on primary molding die
Secondary compression moulding；First molding sheet metal component, the principal outline of the sheet metal component with automobile, and the surface light of primary molding die
Sliding, in pressing process, using hydraulic-driven, hydraulic-driven squeezes sheet metal component, and extrusion process is more stable, and extruding force is bigger,
It can be improved the stability of sheet metal component compacting；
The sheet metal component of first compression moulding is placed on hot forming tool, passes through the upper of hot forming tool by the 4th step, thermoforming
Mold and lower mold squeeze the surface of sheet metal component, so that sheet metal component keeps the general shape of the sheet metal component of automobile, then
Lower mold is heated, so that lower mold temperature rises and transfers heat in sheet metal component, heat can make in the raw material of sheet metal component
Atom and the more active shape to preferably keep the sheet metal component of automobile of molecule；
5th step, it is first to polish, sheet metal component is taken out after thermoforming, the sheet metal component of the shape and automobile of sheet metal component is main at this time
Shape is identical, and sheet metal component can generate the different bending region of thickness during first molding and thermoforming, in order to keep automobile
