Description

Technical Field

[0001] The utility model relates to the technical field of mechanical processing, and more specifically to an anti-displacement device for workpiece stamping. Background Art

[0002] Stamping dies are special process equipment used to process materials (metal or non-metal) into parts (or semi-finished products) during cold stamping. They are called cold stamping dies (commonly known as cold stamping dies). 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. A stamping device is required when processing stamped parts. When stamping a workpiece, it is necessary to fix the workpiece to prevent it from shifting due to pressure.

[0003] Existing workpiece anti-displacement devices generally clamp the workpiece by two groups of square blocks or arc blocks. During operation, the staff rotates the threaded rod to drive the two groups of square blocks or arc blocks to move, so as to prevent the displacement of workpieces of different sizes. However, in actual use, since the processed workpieces are sometimes square and sometimes round, and the installed clamping blocks are generally only square blocks or arc blocks, when the shape of the clamping block does not match the shape of the workpiece, it is necessary to replace the corresponding matching fixture, which is time-consuming and labor-intensive to operate, and has certain limitations in use, affecting the processing efficiency of the workpiece.

[0004] In view of this, we propose an anti-displacement device for workpiece stamping. Utility Model Content

[0029] Specifically, an inner groove 3 is provided on the inner side of the punching table 2, a rotating rod 4 is rotatably provided on the inner side of the inner groove 3, a first bevel gear 5 is fixedly sleeved on the outer side of the rotating rod 4, and a driving motor 6 is fixedly provided on the outer side of the punching table 2, the power end of the driving motor 6 movably passes through the punching table 2 and is fixedly connected to the rotating rod 4, a mounting frame is fixedly provided on the lower side of the punching table 2, and the driving motor 6 is installed on the inner side of the mounting frame to ensure the installation stability of the driving motor 6.

[0030] Furthermore, a plurality of mounting grooves 7 are provided on the upper side of the punching table 2, and a screw rod 8 is rotatably provided on the inner side of each of the plurality of mounting grooves 7. A movable block 9 is threadedly sleeved on the outer side of the screw rod 8, and the outer end of the screw rod 8 is movably penetrated through the inner groove 3 and extends to the inner side. A second bevel gear 10 is fixedly provided on the inner side of the inner groove 3 on the outer side of the screw rod 8. The second bevel gear 10 is meshed with the first bevel gear 5. When the first bevel gear 5 rotates, it can drive a plurality of second bevel gears 10 to rotate at the same time, thereby conveniently driving a plurality of square blocks 14 and a plurality of arc blocks 18 to move at the same time, and conveniently preventing displacement of batches of workpieces.

[0031] It is worth mentioning that a limiting groove 11 for docking the movable block 9 is provided on the inner side of the mounting groove 7. The movable block 9 slides in the limiting groove 11. The limiting groove 11 can limit the movable block 9 so that when the screw rod 8 rotates, it can drive the movable block 9 to move parallel to the screw rod 8, thereby facilitating the movement of the square block 14 or the arc block 18.

[0032] It is worth noting that connecting blocks 15 are fixedly provided on both sides of the mounting block 12, and limiting rods 16 are movably provided on the outer sides of the two groups of connecting blocks 15.

[0033] In addition, a limiting rod 19 is movably provided on the outer side of the movable block 9. The outer end of the limiting rod 19 movably passes through the movable block 9 and extends to the other side. The outer end of the limiting rod 19 is located at the outer part of the movable block 9 and is fixedly connected to the arc block 18.

[0034] It must be said that a turntable is fixedly provided at the outer end of the first threaded rod 13 and the second threaded rod 17. By providing the turntable, the first threaded rod 13 or the second threaded rod 17 can be easily rotated, thereby improving the convenience of operation.

[0035] Working principle: First, according to the shape of the batch of workpieces, multiple groups of square blocks 14 or multiple groups of arc blocks 18 are adjusted separately. When the square block 14 is adjusted separately, the multiple groups of first threaded rods 13 are rotated first. Through the limiting effect of the limiting rod 16, the first threaded rod 13 can move the square block 14 in parallel until the square block 14 moves to a suitable position. When the arc block 18 is adjusted separately, the multiple groups of second threaded rods 17 are rotated again. Through the limiting effect of the limiting rod 2 19, the arc block 18 can be driven to move in parallel until the arc block 19 passes through the through-hole 20 of the square block 14. After 14 or the arc block 18 is adjusted, the workpiece is placed on the punching table 2, and then the driving motor 6 is turned on by an external power supply. The driving motor 6 drives the rotating rod 4 and the first bevel gear 5 to rotate. The first bevel gear 5 can drive multiple sets of second bevel gears 10 to rotate, and the second bevel gear 10 drives the screw rod 8 to rotate. The movable block 9 sleeved on the outside of the screw rod 8 moves parallel to the screw rod 8 under the limiting action of the limiting groove 11. When the movable block 9 moves, it drives the square block 14 and the arc block 18 to move, so that the workpiece can be quickly fixed, the stability of the workpiece is ensured, and the displacement of the workpiece is avoided.
