The limit plate slides relative to the lower template, and a fixing groove for accommodating the adjustment structure is provided at the edge of the upper template.

[0006] The further improvement of the vehicle body cover stamping device of the utility model is that the stripping plate includes a fixed plate, the upper end surface of which is positioned close to the plate and is an inclined surface, and a top plate is hinged at the inclined surface. A through groove is provided on the fixed plate, and the through groove faces the top plate. A push rod is arranged in the through groove for lifting the top plate.

[0007] A further improvement of the punching device for a vehicle body covering part of the utility model is that a through hole is provided on the groove wall away from the plate, and the hole is used for the ejector rod to pass through.

[0008] A further improvement of the vehicle body cover stamping device of the utility model is that the fixed plate is connected to the adjusting rod, and a second hole groove is provided on the groove wall away from the plate, and the second hole groove is used for the adjusting rod to pass through. The adjusting rod is provided with a thread and is screwed with two sets of nuts, and the two sets of nuts are distributed inside and outside the groove.

[0009] A further improvement of the vehicle body cover punching device of the utility model is that a thread is provided on the wall of the through groove, and the push rod is adaptively connected with the thread.

[0010] A further improvement of the vehicle body cover punching device of the utility model is that four groups of adjustment structures are provided and distributed on the four side edges of the lower template.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] The utility model adjusts the structure to limit the plate, thereby ensuring that the plate is in a positioned state during the subsequent upper template stamping, and will not deviate prematurely, thereby ensuring the stability of the stamping; on the other hand, after the cover is stamped and formed, the edge of the plate will protrude excessively, and the use of a stripping plate can efficiently demold the formed plate.

[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0017] like Figure 1 and Figure 2 As shown, a body cover stamping device includes a stamping table 1, a lower template 2 is arranged on the stamping table, an upper template 3 is arranged above the stamping table, and an adjustment structure for limiting the plate and demolding the plate is provided at the edge of the lower template. The adjustment structure includes a limiting plate 4, the limiting plate is L-shaped, and a groove 5 is provided at the edge of the lower template. A stripping plate extending into the groove is connected below the limiting plate, and the limiting plate slides relative to the lower template. A fixing groove for accommodating the adjustment structure is provided at the edge of the upper template.

[0018] Furthermore, the stripper plate includes a fixed plate 6, whose upper end, located near the plate, is inclined. A top plate 7 is hingedly connected to the inclined surface. The top plate's upper end is flush with the upper end of the upper plate. The fixed plate is provided with a through slot, facing the top plate. A push rod 8 is positioned within the through slot to lift the top plate. The front and rear ends of the fixed plate abut against the front and rear walls of the groove. A through hole is provided in the groove wall away from the plate for the push rod to pass through.

[0019] Furthermore, the fixed plate is connected to the adjustment rod 9, perhaps by bolts. A second hole is provided through the wall of the groove, away from the plate, for the adjustment rod to pass through. The adjustment rod is threaded and screwed with two sets of nuts 10, one inside and one outside the groove. These two sets of nuts are used to adjust the position of the limit plate, thereby achieving adjustable clamping and limiting for different plates.

[0020] A thread is provided on the wall of the through groove, and the push rod is adapted to be connected with the thread.

[0021] Furthermore, there are four groups of adjustment structures, distributed on the four sides of the lower template, to ensure the overall positioning stability of the plate.

[0022] The working principle of the present invention is as follows: the covering plate is placed on the lower template, and the nut is adjusted so that the limit plate limits and clamps the plate to achieve positioning. At this time, the adjustment structure is also relatively fixed. Then the upper template punches the plate and the covering is formed. At this time, there will be a gap between the edge of the plate and the limit plate. Then, the upper template is reset, and the push rod is rotated so that the push rod lifts the top plate. Then, the outer nut is adjusted, and the adjusting rod is manually adjusted to move the limit plate to one side of the plate. At this time, the lifted top plate will lift the edge of the plate to achieve demoulding. After demoulding, the body covering will undergo subsequent cutting and other steps.

[0023] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
