Problems solved by technology

At the same time, due to the large radian and large height drop of some covering parts, the initial shape of the sheet metal will fall and bend due to gravity during the processing process. The traditional wedge-shaped positioning plate cannot meet the precise and effective positioning.

Embodiment Construction

[0021] In order to deepen the understanding of the present invention, the present invention will be further described below in conjunction with the examples, which are only used to explain the present invention, and do not constitute a limitation to the protection scope of the present invention.

[0022] like Figure 1-5 As shown, this embodiment provides an adjustable arc-shaped positioning mechanism for stamping die blanks, including a limiting plate 1 with an arc-shaped side and a vertical positioning plate 2 overlapping with the positioning plate 1. A fixed block 3 is fixed; the upper part of the limiting plate 1 and the upper part of the positioning plate 2 are rotatably connected by passing through the rotating shaft 4; the place where the rotating shaft 4 passes on the limiting plate 1 is an axis hole 8; the positioning plate 2, where the rotating shaft 4 passes through is the fixing hole 9; the two ends of the rotating shaft 4 are provided with anti-falling pins 10 and...

Abstract

The invention provides an adjustable stamping die blank arc-shaped positioning mechanism, a limiting plate and a positioning plate with the arc-shaped side faces are arranged in an overlapped mode, the upper portion of the limiting plate and the upper portion of the positioning plate are movably connected through a rotating shaft, the limiting plate is rotatable, a sawtooth screw capable of transversely moving penetrates through the middle of the limiting plate and the middle of the positioning plate, and connection is conducted; and when the limiting plate rotates, the sawtooth screw moves in a sliding groove, and therefore the position angle of the limiting plate can be adjusted in time, adaptability is high, flexibility is good, and precision is high.

Description

technical field [0001] The invention relates to the field of stamping dies, in particular to an adjustable arc-shaped positioning mechanism for stamping die blanks. Background technique [0002] Automobile panels are mostly thin plate structures, which have the characteristics of large overall size and complex shape, so there are extremely high requirements for the precision of sheet metal stamping. Covering parts need to go through a series of complex processes from structural design of parts, process analysis and optimization, mold design and manufacturing to final production debugging. In this process, the quality of the stamping process and the mold structure determines the final forming quality of the cover. Common forming defects include wrinkling, cracking, and springback. [0003] At present, as the shape of automobile cover parts becomes more and more complex, it is particularly important to have a simple and reliable blank positioning device in the production and ...
