Problems solved by technology

The disadvantages that appear in the processing process are generally many procedures, long processing route (that is, two forming processes first and then a shaping process), the processing process is not stable enough, and there is a greater limitation in controlling the quality of profiles. Difficulty, thus resulting in a low product qualification rate

Embodiment Construction

[0013] Such as Figure 1-3 As shown, the process method for processing a heat shield for automobiles according to the present invention includes the following steps:

[0014] (1) First, prepare and adjust the molding die equipment. The main processing units include the molding die 1, the core rod, the die, the feeding mechanism, the pressing mechanism and the punching mechanism. First, the metal ring 2 to be processed is placed in the molding In the working area of ​​the processing and forming die 1 of the equipment;

[0015] (2) Put the metal ring part to be processed into the working area of ​​the forming cavity of the forming equipment, and pass the metal ring part through the same pair of forming molds. First, the upper mold moves downward, and the plate is formed to a certain extent. After moving through the top cylinder, the upper mold continues to descend and contacts the lower mold, and the plate is bent into a circle in the lower mold cavity to realize the processing proc...

Abstract

The invention provides a method for processing an automobile heat shield. The main processing steps are as follows: a metal ring workpiece to be processed is put in the processing and molding female die working area of a molding device, the workpiece is then molded by a pair of molding dies, the workpiece is molded by an upper die from up to down to mold the plate to a certain shape, the upper die continues down by piston movement and contacts with a lower die to enable the plate to be bent into a round shape in a lower die cavity, thereby realizing a processing process from plate to big ring, and finishing ring molding operation by regulating the master cylinder pressure, lower piston pressure and hold-up time of a hydrostatic press. The invention greatly lowers cost, simplifies working procedures by half, reduces input of equipment, labour, site and the like, conforms to energy saving standard and has sound environment protection effect. The ring molding has good effect, stable quality performance and higher cost performance.

Description

Technical field [0001] The invention relates to a processing method of automobile parts, in particular to a process method of processing a heat shield for automobiles. Background technique [0002] At present, most of the widely used auto parts shields are made of steel stamping. The thickness of the plate is about 1mm, and the diameter is about φ110mm. Since the diameter of the formed ring is greater than 40mm, it is usually formed in two steps, namely first bending into a wave shape, then bending into a circle, and finally shaping. The disadvantages that appear in the processing process are generally that there are more procedures, the processing route is long (that is, two forming procedures are carried out first, and then a reshaping procedure), the processing procedure is not stable enough, and the quality of the control profile is relatively large Difficulty, which leads to a low product qualification rate. Summary of the invention [0003] In view of the above shortcoming...
