Problems solved by technology

[0005] Option 1: Adding blanking dies can improve the drawing performance of the sheet metal, and the quality of the parts is better, but the investment cost is high; in the case of the company's production, the material utilization rate is low, and a blanking production process needs to be added; it is necessary to increase the investment in personnel and equipment
Option two is direct drawing. If the window frame waste is removed later, the material utilization rate of the parts is too low

Embodiment Construction

[0023] Figure 1 shows a co-molding production method for automotive panels, including drawing, trimming and punching, flanging and shaping and side cutting.

[0024] This process technology is aimed at side wall inner panel parts, and the specific steps are as follows:

[0025] 1. Drawing: use a square plate of 0.7mm×1780mm×1365mm to stretch out the basic shape of the part;

[0026] 2. Trimming and punching: Punching off the peripheral and intermediate shape holes of the parts and the excessive holes to be processed in the subsequent sequence;

[0027] 3. Flanging shaping: Reshape the position with high requirements and small R angle, and flanging the supporting position and surrounding shape of the glue;

[0028] 4. Reshaping side cutting: cut off the incomplete edge trimming around the pre-order, trim the parts partially, punch process holes, positioning holes and installation holes, and separate the two parts from different positions for storage.

[0029] To sum up: this ...

Abstract

The invention discloses a common mode manufacturing method for an automobile covering part. The method includes the steps of drawing, trimming deflashing punching, flanging shaping and shaping side cutting. The process technology is used for inner plate parts on the side periphery. At first, the basic shape of each part is drawn out by means of a square plate, then shape holes in the periphery and the middle of each part and transition holes needing to be machined at later procedures are punched, shaping is carried out on high required positions and small R angles, flanging is carried out on gluing supporting positions and periphery modeling, and finally positions with incomplete trimming deflashing on the periphery of former procedures are cut off, side trimming is conducted on a part of each part, process holes, positioning holes and installation holes are punched, and the two parts are separated and taken out of different positions to be stored. The process technology breaks through the thought that one kind of parts is produced through a pair of molds, the utilization rate of materials is improved, mold investment and material investment of the parts are reduced, investment of staff, equipment and production time in procedures of the later period is eliminated, and the method plays an active role in the overall energy conservation effect enhancement plan of enterprises.

Description

technical field [0001] The invention relates to lost foam casting technology, which belongs to the field of casting technology, and in particular to a co-molding production method of an automobile cover part which can be applied to special steel casting. Background technique [0002] Our company has newly developed a certain model, and the parts involved need to develop new molds. Among them, the rear side wall inner panel parts ( figure 1 ), the material is SPCE, the thickness of the parts is 0.7mm, and the dimensions of the parts are: 1573mm×1082mm×275mm. Due to the complex shape of the part, the deep drawing depth, and the high difficulty of forming; and the large area of ​​​​the window frame (984mm×425mm), there are two options according to the normal process: [0003] Option 1: Increase the blanking die. That is, before drawing forming, the plate is cut into an appropriate shape, and the feeding conditions of the drawing are balanced in order to improve the drawing p...
