Description

Technical Field

[0002] A stamping die is a special process equipment used to process materials (metal or non-metal) into parts (or semi-finished products) during cold stamping. It is called a cold stamping die (commonly known as a cold stamping die). Stamping is a pressure processing method that uses a die installed on a press to apply pressure to the material at room temperature to separate or plastically deform the material, thereby obtaining the desired parts. During the operation of the existing stamping die, the formed workpiece will adhere to the upper die due to stamping and will be difficult to detach from its bottom. In the prior art, a stripper plate that cooperates with the die is usually provided to prevent the die from adhering to the bottom of the upper die. However, during the stamping process, part of the sheet material will adhere to the lower die due to extrusion, thereby affecting the demoulding of the workpiece, and also affecting the separation between the upper die and the lower die, thereby affecting the use efficiency of the entire stamping die.

[0014] Beneficial effects of the present invention:

[0015] 1. By setting up a special upper and lower matching demoulding structure to replace the original unloading plate demoulding structure, the possibility of the plate adhering to the upper die can be reduced. At the same time, it can also ensure that the plate can only adhere to the upper die to a certain extent, thereby solving the problem that when the existing stamping die is in use, part of the plate will adhere to the lower die due to the vertical pressure on the plate, making it difficult for the plate entering the lower die to be separated from the lower die, thereby affecting the working efficiency of the entire stamping die;

[0016] 2. By setting up an auxiliary frame and a discharge push plate, the plate can be confined to the inner side of the discharge push plate, and after the punch head is separated from the lower die block through the air outlet hole set on the lower die base, the compressed air can be directly passed into the interior of the air supply pipe through the air inlet head, and sent into the interior of the air supply groove through multiple connecting pipes, so that the discharge push plate located at the upper end of the lower die base can be quickly separated from the auxiliary frame under the action of the air outlet hole. At the same time, under the action of compressed air, a gap can also be formed between the lower die base and the workpiece, thereby preventing the workpiece from adhering to the lower die base. At the same time, the screw slide rail drives the screw slider to move, so that the screw slider drives the discharge push plate to move, and the workpiece adhering to the punch head is separated, thereby greatly improving the working efficiency of the entire stamping die;

[0017] 3. The first meshing wheel is driven to rotate by the first driving motor, so that the first meshing wheel drives the active rotating wheel to rotate, and drives the passive rotating wheel to rotate under the action of the transmission belt, and drives the second meshing wheel to rotate through the passive rotating wheel, and the rotating second meshing wheel also drives the third meshing wheel to rotate, and the rotating third meshing wheel and the first meshing wheel can drive the second sliding bar to move horizontally, and the horizontal movement of the second sliding bar will drive the synchronous gear meshing with the meshing teeth to rotate, and the rotation of the synchronous gear will drive the first sliding bar located at the upper end of the synchronous gear to move horizontally, and the horizontally moving first sliding bar and the second sliding bar respectively drive the first connecting slide and the second connecting slide to move in opposite directions or towards each other, so that the movement between the two guide components can be realized, so that the stamping die can adapt to feed plates of different specifications to improve the applicability of the stamping die;

[0018] 4. The bidirectional screw rod is driven to rotate by the fourth driving motor, and the rotating bidirectional screw rod is used to guide the two positioning sliders to move in opposite directions or towards each other. Under the action of the positioning slider, the two adjusting columns will slide in the limit grooves on the combination plate, so that the adjusting columns can drive the two rotating seats to move respectively, and the second driving motor installed on the rotating seat can drive the guide rollers to rotate, and the displacement guidance of the plate is achieved by the rotating guide rollers. At the same time, when the positioning slider is controlled to move to the front and rear end positions, the guide wheels can be engaged with them, and the third driving motor drives the guide wheels to rotate to drive the entire rotating seat to rotate. Along with the rotation of the rotating seat, the position of the plate when moving in the horizontal direction can be changed to a certain extent, so that by driving different positions and different numbers of guide rollers, the plate can be displaced during the movement, so that the stamping die can be stamped in multiple directions, thereby greatly improving the working efficiency of the entire stamping die.

[0042] The combination plate 705 is provided with a limiting groove 706; a rotating seat 707 is installed at the upper end of the adjusting column 703; a second driving motor 709 is installed on the rotating seat 707; a guide roller 708 is rotatably connected to the second driving motor 709 via a coupling; a guide wheel 711 is rotatably connected to the shield frame 701; the upper end of the guide wheel 711 is rotatably connected to the third driving motor 712 via a rotating shaft; a plurality of guide teeth 710 are fixedly connected to the outer surface of the rotating seat 707; the guide teeth 710 and the guide wheel 711 are arranged to mesh.

[0043] When working, first install the gas cylinder on the gas inlet head 202 through the air pipe, and drive the first meshing wheel 403 to rotate through the first driving motor 402 according to the specifications of the plate, so that the first meshing wheel 403 drives the active rotating wheel 404 to rotate, and drives the passive rotating wheel 406 to rotate under the action of the transmission belt 405, and drives the second meshing wheel 407 to rotate through the passive rotating wheel 406, and the rotating second meshing wheel 407 will also drive the third meshing wheel 409 to rotate, and the rotating third meshing wheel 409 and the first meshing wheel 403 can drive the second sliding bar 503 to move horizontally, and the horizontal movement of the second sliding bar 503 will drive the same meshing tooth 506 meshing with the meshing tooth 506.

[0044] During the sheet stamping process, the sheet can be confined inside the discharge push plate 313 through the auxiliary frame 106 and the discharge push plate 313, and after the punch head 308 is separated from the lower die block 105 through the air outlet hole 205 provided on the lower die base 103, the compressed air can be directly introduced into the interior of the air supply pipe 201 through the air inlet head 202, and then sent into the interior of the air supply groove 204 through the multiple connecting pipes 203, so that the sheet located on the lower die base 103 can be pressed by the air outlet hole 205.

With the rotation of the rotating seat 707, the position of the plate when moving in the horizontal direction can be changed to a certain extent, so that by driving different positions and different numbers of guide rollers 708, the plate can be displaced during the movement, so that the stamping die can be stamped in multiple directions, thereby greatly improving the working efficiency of the entire stamping die.

[0046] Through the above steps, a special embedded thin wire structure is set to replace the original thick wire structure to improve the product qualification rate and reduce the additional transformer cost, which can to a certain extent solve the problem that when the existing stamping die is used, the heating of the workpiece inside the equipment is mostly achieved by setting a corresponding thick heating wire structure inside the equipment. However, the setting of the thick heating wire will cause the device to need to additionally set a corresponding transformer, which will result in an increase in the size of the equipment and an increase in the cost of using the equipment.
