Mold and method for forming and processing automobile side wall outer panel

Abstract

The invention provides a mold and method for forming and processing an automobile side wall outer panel. The processing mold includes an upper mold base, a lower mold base, a lower mold insert and a shaping insert; the lower mold insert is fixedly arranged on the lower mold base, and the lower mold base The mold insert is provided with a punching die; the upper mold base is arranged above the lower mold base in an open or closed manner relative to the lower mold base; the shaping insert is arranged on the lower end surface of the upper mold base, and Relatively set; the shaping insert is used to shape the rear protection part of the side wall outer plate between the shaping insert and the lower die insert; it also includes a punch, which is set on the upper die seat facing the punching die Above, it is used to punch holes in the rear protection part of the side wall outer plate between the shaping insert and the lower mold insert; with the above scheme, the shaping and punching of the side wall outer plate can be integrated in the same process, reducing The processing steps of the side wall outer plate reduce the processing cost of the side wall outer plate; the solution provided by the invention has ingenious structural design, simple manufacture, low cost, and reduces the mold development cost.

Description

technical field [0001] The invention belongs to the technical field of stamping and forming of automobiles, and in particular relates to a mold and method for forming and processing an automobile side wall outer panel. Background technique [0002] Such as figure 1 As shown, when the existing automobile body side wall outer panel 100 is drawn and formed, in order to meet the forming quality requirements of the prismatic slip line of the side wall outer panel 100, the stamping direction in the drawing process needs to be rotated by an angle α° relative to the direction p of the vehicle body. The back protection part of the side wall outer panel 100 cannot be drawn in place according to the shape of the product in the drawing process. For the processing of the mounting hole 200, according to the traditional technology and mold structure, after the shaping is completed, it is necessary to arrange a process for punching the mounting hole. According to the traditional process, f...
