Problems solved by technology

[0002] At present, the fenders with charging ports of other car companies have six processes, and some companies have only five processes in their production lines, which makes it impossible to produce fenders with charging ports.
The initial plan is outsourced production of molds and stamping parts in full sequence. After amortization of stamping parts, the cost is relatively high, and production and quality control of parts are more difficult.

Embodiment Construction

[0053] If the charging port of the product follows the traditional process, the first process of drawing will fill the charging port, and the second process of pre-trimming, the fifth process of flanging and shaping, and the sixth process of fine trimming three process contents, among which the first process should be avoided. The third process is the wedge shaping process on the side where the hair cover overlaps and the fourth process is the wedge shaping process on the side where the door overlaps, so the fender with the charging port needs six processes. In order to realize the five processes, it is also necessary to avoid the oblique wedge shaping process on the overlapping side of the hair cover in the third process and the oblique wedge shaping process on the overlapping side of the door in the fourth process. Only by changing the shape of the drawing process, the drawing process of the first process The middle charging port is preformed, the second process is pre-trimmi...

Abstract

The invention belongs to the technical field of stamping, and particularly relates to a technology for a fender with a charging port. The process comprises the following steps of 1, designing a drawing technology; 2, carrying out product modification; and 3, optimizing a structure. According to the technology, the problem that the process of the product is long can be primarily solved, five-process production is thoroughly realized through whole-process technology improvement, and the technology has great popularization and application significance in lowering the mold investment and improvingthe production efficiency; and secondly, the technology improvement scheme is also put forward for the defects of the appearance surface quality, which plays a guiding role in shorting the debuggingperiod of a mold and improving the appearance surface quality of a workpiece.

Description

technical field [0001] The invention belongs to the technical field of stamping, in particular to a fender process with a charging port. Background technique [0002] At present, the fenders with charging ports of other car companies have six processes, and some companies have only five processes in their production lines, which makes it impossible to produce fenders with charging ports. The early planning is outsourced production of molds and stamping parts in full sequence. After amortization of stamping parts, the cost is relatively high, and it is difficult to control the quality of production and parts. [0003] In order to achieve in-house production, the conventional six-sequence process was shortened to five sequences, and a new process planning and product structure optimization were carried out for the parts to ensure the five-step production of the parts, which not only ensures the surface quality and dimensional accuracy of the parts. Requirements, and greatly r...
