Description

A stamping device for stainless steel washers Technical Field

[0001] This utility model belongs to the technical field of stamping devices, specifically a stamping device for stainless steel washers. Background Technology

[0002] Stainless steel washers are ring-shaped fasteners made of stainless steel. They are mainly used in mechanical assembly and play a key role in distributing pressure, preventing loosening, protecting contact surfaces, and preventing corrosion by being placed between bolts, nuts, or connectors.

[0003] A search revealed that the utility model patent with publication number CN211660833U discloses a sealing gasket stamping device. The background section mentions using a spring to fix the workpiece. However, the spring itself has elasticity, making it unstable when fixing the workpiece. This can lead to loosening and ejection during stamping, posing a safety hazard and reducing performance. The solution addresses this by designing a sleeve rod to mount a fixing rod on the work platform. The workpiece is then placed in a through hole. Rotating the rotating head causes the fixing rod to rotate downwards inside the sleeve rod. The fixing rod then moves the pressure plate downwards, bringing the pressure plate into contact with the workpiece. The upper outer surface contacts the workpiece, and then the locking nut is rotated to make it tightly contact the upper outer surface of the sleeve rod. This prevents the fixing rod from loosening and fixes the distance between the pressure plates on the fixing rod. The two pressure plates then fix the workpiece, increasing the stability of the workpiece fixation. However, in actual use, the workpiece needs to be placed inside the through hole. Since the through hole is located inside the work platform, the operator cannot clearly observe whether the workpiece is placed in place. If the workpiece is placed in a wrong position, the stamped washer will not meet the design requirements. Therefore, improvements are needed. Summary of the Invention

[0004] The purpose of this invention is to address the above-mentioned problems. This invention provides a stamping device for stainless steel washers, which has the advantage of facilitating the placement of workpieces.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] As shown in Figures 1 to 5, this utility model provides a stamping device for stainless steel washers, including a workbench 1. A placement plate 2 is movably installed inside the workbench 1. Side plates 3 are fixedly installed on both the left and right sides of the placement plate 2. Horizontal plates 4 are fixedly installed on the inner side of the side plates 3. There are two horizontal plates 4. Mounting blocks 5 are fixedly installed on the front and rear sides of the top of the two horizontal plates 4. A double-threaded rod 6 is movably sleeved between the mounting blocks 5. Moving blocks 7 are threadedly sleeved on the front and rear sides of the outer surface of the double-threaded rod 6. The bottom of the moving blocks 7 is movably connected to the top of the horizontal plates 4. A hinge rod 8 is hinged to the bottom end of the moving blocks 7. A pressure plate 9 is hinged to the bottom end of the hinge rod 8. A motor 10 is fixedly installed at the bottom of the inner surface of the workbench 1, located behind the placement plate 2. The motor 10 outputs... The other end of the output shaft is fixedly connected to a rotating shaft 11. A rotating rod 12 is fixedly sleeved on the outer surface of the rotating shaft 11. A push-pull rod 13 is hinged to the other end of the rotating rod 12. The other end of the push-pull rod 13 is hinged to the back of the placement plate 2. The operator starts the motor 10, which causes the rotating shaft 11 to drive the rotating rod 12 to rotate, thereby causing the push-pull rod 13 to push the placement plate 2 forward, making it easier for the operator to place the workpiece inside the placement plate 2. When the double threaded rod 6 rotates, since the front and rear threads on the outer surface of the double threaded rod 6 are in opposite directions, the double threaded rod 6 can drive the two moving blocks 7 to move in opposite directions when it rotates, so that the hinged rod 8 can push the pressure plate 9 downward, thereby pressing the workpiece.

[0022] The workbench 1 has a support frame 14 fixedly installed on top, and a pneumatic cylinder 15 fixedly installed on top of the support frame 14. The bottom end of the pneumatic cylinder 15 passes through the support frame 14 and is movably sleeved with the inner surface of the support frame 14. A punch 16 is fixedly installed at the bottom of the pneumatic cylinder 15. The operator can start the pneumatic cylinder 15 to make the punch 16 move downward, thereby stamping the workpiece.

[0023] The workbench 1 has a through hole 17 at the top and a discharge port 18 at the bottom. By setting the through hole 17, the punch 16 can move downward and punch the workpiece through the through hole 17. The punched washer will fall through the discharge port 18 for discharge.

[0024] Among them, limit rods 20 are fixedly installed on the left and right sides of the top of the pressure plate 9. The top of the limit rod 20 passes through the horizontal plate 4 and extends to the top of the horizontal plate 4 and is movably sleeved with the inner wall of the horizontal plate 4. By setting the limit rod 20, the pressure plate 9 can drive the limit rod 20 to move up and down along the inner wall of the horizontal plate 4 when it rises or falls, so that the pressure plate 9 can rise or fall more stably.

[0025] The double threaded rod 6 has a rotating block 19 fixedly sleeved on the front side of its outer surface, and four support legs 23 are fixedly installed at the four corners of the bottom of the workbench 1. The operator can rotate the rotating block 19 to make the double threaded rod 6 rotate, thereby enabling the pressure plate 9 to move downward to press and fix the workpiece.

[0026] There are two round rods 22 that are movably connected inside the left and right sides of the workbench 1. The two round rods 22 are the same size. By setting the round rods 22, the round rods 22 can move outward when the placement plate 2 moves outward, so that the placement plate 2 can move more smoothly when it moves outward.

[0027] The front end of the placement plate 2 is fixedly installed with a connecting plate 21, and the back of the connecting plate 21 is fixedly connected to the front end of the round rod 22. When the placement plate 2 moves forward, the connecting plate 21 will drive the round rod 22 to move outward along the inner wall of the worktable 1, so that the placement plate 2 can move more stably.

[0028] Working principle and usage process of this utility model:

[0029] When stamping is required, the operator first starts the motor 10, which causes the rotating shaft 11 to rotate the rotating rod 12, thereby causing the push-pull rod 13 to push the placement plate 2 forward. When the placement plate 2 moves forward, it will drive the round rod 22 to move outward along the inner wall of the placement plate 2 through the connecting plate 21, thus supporting the placement plate 2. At this time, the operator can place the workpiece inside the placement plate 2, and then rotate the rotating block 19, which causes the double threaded rod 6 to drive the two moving blocks 7 to move in opposite directions. This causes the pressure plate 9 to descend under the limiting action of the limiting rod 20 through the hinge rod 8, so that the pressure plate 9 presses and fixes the workpiece. Then, by starting the motor 10 again, the rotating shaft 11 reverses, thereby driving the placement plate 2 to reset through the push-pull rod 13.

[0030] Then, the operator starts the pneumatic cylinder 15, which drives the punch 16 downward, so that the punch 16 enters the interior of the worktable 1 through the through hole 17, thereby stamping the workpiece. The stamped washer will be discharged through the discharge port 18.
