Problems solved by technology
In the debugging stage, because the sheet itself is also left-right symmetrical, since there is no auxiliary positioning structure, it is completely dependent on visual positioning, and generally needs to adjust the material shape 2 to 4 times to determine the final blanking shape, so there are the following Disadvantages: It is difficult to determine the installation position of the positioning plate, and it is necessary to try and adjust the mold on the press many times, resulting in waste of sheet metal, long mold debugging cycle, increased equipment loss, etc.; through this patent, many of the above-mentioned shortcomings can be solved

Embodiment Construction
[0034] The process of preparing the sheet for positioning is as follows:
[0035] Step 1: The theoretical material shape line of the automobile sheet metal parts developed by CAE software, such as figure 1 ; Add two Φ16 positioning holes 31 material shape line on the material shape; the positioning hole is a process hole for assisting in quickly determining the final shape of the final material shape line.
[0036] Step two: image 3 Express basis figure 2 The shape of the material, the laser cuts out the sheet, and after pressing through the molding die, according to the test results of the process parts, the material shape line after the first adjustment;
[0037] Figure 4 Express basis image 3 The shape of the material, the laser cuts out the sheet, and after pressing through the molding die, according to the test results of the process parts, the material shape line after the second adjustment;
[0038] then based on Figure 4 The shape of the material, the laser ...

The invention discloses a compression mold and method for rapidly determining an installation position of a positioning board. The compression mold and method are used for solving the problem that the position of an existing positioning board in the compression mold can not be positioned rapidly. A long round hole and a cylinder pin hole are formed in the positioning board, and the positioning board is positioned through a cylinder pin and a fastening screw and fixed on the upper surface of a lower mold seat body of the periphery of a lower mold forming embedded lump. At least two positioning pins are inserted into a material supporting body, and positioning pin holes matched with the positioning pins are formed in the lower surface of an upper mold forming embedded lump. The position of the positioning board is determined by determining the position of panel veneer through the positioning pin, after the position of the positioning board is determined and fastened, the positioning pins can be detached. The positioning pins do not exist in a normal production process. Due to the existence of the positioning pins and the positioning holes, a final material forming line can be rapidly determined, the number of adjusting times for mold debugging is reduced, a use amount of the panel veneer is reduced, and a mold debugging cycle of the mold is shortened.
Description
technical field [0001] The invention relates to the technical field of stamping dies for automobile sheet metal parts, in particular to a die and a method for quickly determining the installation position of a positioning plate. Background technique [0002] The profiling mold in the automobile stamping die used to produce automobile sheet metal parts, in the stamping die, when placing the sheet, it is necessary to install the sheet positioning plate or positioning pin, the purpose is to adjust and control the blanking die in the previous process The position of the falling sheet on the molding die is to ensure that the qualified process parts are obtained after the sheet is pressed through the molding die. [0003] For the automobile sheet metal parts manufactured by blanking first and then pressing, some of the sheet metal parts are general-purpose parts with left and right symmetry, and there are no holes in the sheet metal parts. , only by using the positioning plate on...
