Description

Technical Field

[0001] The invention relates to the field of stamping manufacturing, and in particular to a pad guiding and positioning device installed on a press machine and an application thereof. Background Art

[0002] At present, domestic stamping production lines, especially manual production lines, mostly use pads to assist in mold installation due to versatility issues. During the installation process, after the upper mold is connected to the pad, the upper mold clamp of the press clamps the pad in a fixed position to complete the mold installation.

[0003] During the production and disassembly of molds, since the clamping rod of the clamp needs to be accurately aligned with the clamping groove of the pad, the position of the pad is mostly manually corrected by the operator after it is placed in place. This method not only increases the labor intensity of the operator and affects the efficiency of mold installation, but also easily causes the pad to shift during the secondary placement of the inner pad. If it is not discovered in time, it will cause the risk of collision and deformation of the clamping rod, all of which have a certain impact on production efficiency. Summary of the invention

[0004] In view of the above existing problems, the purpose of the present invention is to solve the problem that the position of the pad is inaccurate during the die loading process of stamping production, manual correction is time-consuming and labor-intensive, and accurate positioning cannot be guaranteed. The present invention can not only improve the die loading efficiency, but also effectively avoid the risk of collision and deformation of the equipment clamping rod caused by the displacement of the pad. The specific technical solution is as follows:

[0005] A guide positioning device for installing a mold pad, the device is composed of a T-nut, a guide block and a guide fixing plate; the T-nut is provided with two threaded through holes, the guide block is provided with two countersunk through holes matching the threaded through holes; the guide fixing plate is provided with four countersunk through holes;

[0006] Furthermore, the T-nut is made of No. 35 steel, and the guide block and the guide fixing plate are made of No. 45 steel.

[0007] Furthermore, the edges of the guide block on the outside in the vertical direction are chamfered, the edges of the guide contact and running-in surface in contact with the guide fixing plate are arc-shaped, and the symmetrical areas on both sides of the bottom are set as inclined surfaces.

[0008] Furthermore, the edge of the guide fixing plate in contact with the mounting groove is chamfered, and the top area of ​​the contact surface with the guide block is set as an inclined surface.

[0009] Furthermore, the contact surfaces of the guide block and the guide fixing plate are quenched to a hardness of HRC45-50.

[0010] Furthermore, two sets of the device are installed on the left and right of a single press.

[0011] The device is used to calibrate the position of the pad of a stamping press. When in use, bolts are used to connect the T-nut and the guide block from the bottom of the guide block upward through the countersunk through hole and the threaded hole, and the T-nut is installed in the T-slot at the bottom of the press slide; an installation slot is opened on the press pad, and the position of the installation slot corresponds to the T-slot of the press. The guide fixing plate is installed in the installation slot of the press pad through the countersunk through hole, and the installation position is to fix the top of the guide plate flush with the top of the press pad. After the installation is completed, the press slide starts to prepare for die loading. When the T-nut and the guide block are ready to contact the press pad as the slide moves, they can be automatically guided by contacting and pushing the guide fixing plate to correct the position of the pad, so as to achieve the effect of precise positioning of the pad.

[0012] The beneficial effects of the present invention are as follows: 1) The present invention is installed at the bottom of the slide of the press machine, and can automatically guide and position the mold pad during the downward movement of the slide, without the need for manual correction of the pad, thereby reducing the labor intensity of the operator in the mold installation and improving the efficiency of mold installation; 2) The present invention can automatically position the pad accurately through the guiding action during each mold installation, thus avoiding collision damage between the pad and the clamping rod of the press machine due to position deviation. 3) The present invention has a wide range of applications. By changing the size or structural orientation, it can be applied to all presses to perform positioning operations of the pad in all directions, and has a high promotion value.
