Description

Posture adjustment bracket for manufacturing automobile door outer plate, punching machine and manufacturing method Technical Field The invention relates to the technical field of automobile manufacturing, in particular to a posture adjusting bracket, a punching machine and a manufacturing method for manufacturing an outer plate of a vehicle door. Background In recent years, vehicle types with a bias motion in an integral style are more and more favored by more consumers, and the door outer plate of the vehicle type is generally provided with a modeling characteristic of folding into the vehicle in a threshold area, and after the threshold area is turned over in a stamping direction, the modeling can cause overlarge stitching open edge angle, so that the stitching efficiency of the inner plate and the outer plate of the vehicle door is influenced, and meanwhile, the stitching quality problem is brought, so that corresponding measures are required to be taken in the stamping process to reduce the stitching open edge angle. Referring to FIG. 1, the conventional stamping process of the outer plate of the automobile door comprises the steps of drawing OP10, trimming OP20, separating the outer plates of the OP30, separating the outer plates of the left door and the right door, flanging OP40, and flanging the peripheral outline of the part, wherein the forming of the outer cover surface of the outer plate of the automobile door is completed through a female die, a male die and a pressing ring of a drawing die. For the traditional stamping process, the front procedure part of OP30 is attached to the OP40 die through self gravity and modeling characteristics, the front procedure part is grabbed by a front procedure manipulator and moved to the thirty centimeters above the flanging die to release the grabbing, the front procedure part freely falls on the flanging die, and the outer plate of the vehicle type door with the whole style deflection motion is excessively large due to the fact that the inner arc is excessively large (the bending angle of the upper end and the lower end of the outer plate of the door is larger than three degrees), when the automatic line of the stamping machine is produced at high speed, the front procedure part is always subjected to stamping processing under the conditions that the positioning of the front procedure part on the flanging die is inaccurate or even not in place, the front procedure part is poor in dimensional accuracy and stability, and the rear procedure part is suddenly stopped, so that the production efficiency is affected. Disclosure of Invention In order to solve the problems, the invention provides the posture adjustment bracket for manufacturing the outer plate of the vehicle door, the punch press and the manufacturing method, wherein the posture of the front procedure part after trimming is changed through the posture adjustment bracket, the stamping direction of the flanging procedure mould is not required to be changed, the positioning accuracy when the front procedure part is hard landed on the flanging procedure mould during the high-speed production of the punch press is ensured, the dimensional accuracy and the stability of the part produced in the flanging procedure are high, the production line works smoothly, and the production efficiency is improved. The invention provides a manufacturing posture adjusting bracket of a vehicle door outer plate, which comprises a rotating angle adjusting bracket and a part profiling material supporting molded surface; The part profiling support material profile is fixed at the upper end of a rotating angle adjusting bracket, the rotating angle adjusting bracket can drive the part profiling support material profile to rotate forward/backward by a certain angle in the front-back direction of the part profiling support material profile (the front-back direction is the direction consistent with the length of a chute of a workbench of a punching machine, the left-right direction is the direction perpendicular to the length of the chute of the workbench of the punching machine), the rotating angle adjusting bracket firstly drives the part profiling support material profile to rotate to the angle consistent with the profile of the previous working procedure, a mechanical arm moves the part of the previous working procedure of the offset vehicle type door outer plate processing to a thirty-male part right above the part profiling support material profile to release the part, the part free falling body moves towards the part profiling support material profile, and the part is finally the falling surface contacts the part profiling support material profile because the form angle of the part of the free falling body is consistent with the part angle of the part profiling support material profile, instead of the prior art that one end of the part in the former procedure falls down to be in line contact with the corresponding end surface
