Embodiment Construction

[0032] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.

[0033] This embodiment discloses a forming method for a large-sized integrated side wall outer panel. By adopting this forming method, it is possible to solve the difficulty in purchasing raw materials due to the large width of the blank material plate that exists in the stamping production of the traditional super-large-sized side wall outer panel. Problems and the mold cannot be installed and the mold is difficult to lift and transfer due to the excessive size of the mold.

[0034] At the same time, in the present invention, since the side wall outer plate adopts the integral stamping and forming scheme, it also solves the problem of the large number of parts in the split side wall outer plate solution, which leads...

Abstract

The invention discloses a forming method of a large-size integrated body side outer panel, and relates to the field of machining of automobile body side outer panel. Drawing of the body side outer panel is achieved through a drawing die, and a top cover side female die and an upper pressure plate are arranged in an upper die body of the drawing die; a top cover side male die, a large blank holder capable of being compressed to move and an outer blank holder are arranged in a lower die body, and a limiting block for limiting a moving path of the outer blank holder is further arranged on the lower die body; the top cover side male die corresponds to the top cover side female die; the outer blank holder corresponds to the upper pressure plate; and through the drawing forming steps of S1, blank holder closing, S2, material plate preliminary forming and S3, drawing forming, the purposes of changing a traditional machining method and improving the part blank material utilization rate are achieved.

Description

technical field [0001] The invention relates to the field of processing steam side wall outer panels, in particular to a forming method suitable for large-size integrated side wall outer panels. Background technique [0002] The side panel is a common outer covering on the car body. It is the largest part among all body sheet metal parts. It has the characteristics of complex shape and many overlapping matching relationships. [0003] In the traditional side wall forming scheme, cold stamping is often used for drawing and forming. This scheme is closed and drawn along the circumference, and the drawing depth is relatively deep. The size of the required blank sheet is large, and the utilization rate of the sheet is not good for super-sized side panels. , due to the large size of the parts, if this scheme is used for forming, it will often result in a large size of the drawn blank, and the coil width exceeds the normal rolling range of general steel mills. Especially when the...
