Description

Technical Field

[0001] This utility model belongs to the field of stainless steel gasket technology, specifically a demolding mechanism for stamping stainless steel gaskets. Background Technology

[0002] Stainless steel washers are ring-shaped fasteners made of stainless steel that play an important role in mechanical assembly, equipment connection and other fields. They are usually placed between bolts, screws or nuts and the surface of the connecting parts. Their main function is to distribute pressure and prevent the surface of the connecting parts from being damaged by concentrated pressure.

[0003] Stainless steel washers are typically produced using a punch press. First, a disc is punched out of the material, and then an inner hole is punched into the disc. This two-stage punching process is common. During the punching process, the disc fits tightly against the mold, and stainless steel itself has a certain degree of elasticity and toughness. As a result, after punching, the disc can easily get stuck in the mold and be difficult to remove. Operators often need to manually remove the washer from the mold, which not only affects production efficiency and increases the difficulty of manual operation but also poses certain safety hazards. Therefore, improvements are needed. Utility Model Content

[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] like Figures 1 to 5 As shown, this utility model provides a demolding mechanism for stamping stainless steel washers, including a housing 1. A lower mold 2 is fixedly installed on the top of the housing 1. A horizontal plate 3 is fixedly installed on the top right side of the lower mold 2. A vertical rod 4 is movably installed on the right side inside the horizontal plate 3. The top end of the vertical rod 4 extends above the horizontal plate 3 and is fixedly sleeved with a connecting plate 5. A circular sleeve 6 is fixedly connected to the left end of the connecting plate 5. A support plate 7 is fixedly installed on the left side of the top of the housing 1. A fixing box 8 is fixedly installed on the top of the support plate 7. A spring 9 is fixedly installed on the top of the inner surface of the fixing box 8. A circular plate 10 is fixedly connected to the bottom end of the spring 9. The bottom of the circular plate 10 is connected to the support plate 8. The top of the support plate 7 is movably connected, and the bottom of the circular plate 10 is fixedly connected to a protrusion 11. The bottom end of the protrusion 11 extends to the outside of the support plate 7 and is movably sleeved with the inner surface of the support plate 7. The operator places the disc to be stamped inside the circular sleeve 6. When the vertical rod 4 moves to the left, it will drive the circular sleeve 6 to move to the left through the connecting plate 5, so that the circular sleeve 6 moves the disc to the top of the lower mold 2, thereby enabling the disc to be stamped and the disc to be stamped into a washer. When the circular sleeve 6 continues to move to the left, the washer will detach from the contact with the lower mold 2 and fall out of the interior of the circular sleeve 6 under the action of gravity.

[0022] Among them, side plates 12 are fixedly installed on both the left and right sides of the bottom of the horizontal plate 3, and limit rods 13 are fixedly installed on both the front and rear sides between the side plates 12; there are two limit rods 13, and the outer surfaces of the two limit rods 13 are smooth.

[0023] The right side of the outer surface of the limiting rod 13 is movably sleeved with the limiting block 14, and the inner wall of the limiting block 14 is fixedly sleeved with the outer surface of the vertical rod 4. When the limiting block 14 moves to the left, it will drive the vertical rod 4 to move to the left. When the limiting block 14 moves, the limiting rod 13 can limit the limiting block 14, thereby preventing the limiting block 14 from rotating, and thus preventing the vertical rod 4 from rotating.

[0024] A servo motor 15 is fixedly installed on the top right side of the housing 1. A round shaft 16 is fixedly connected to the other end of the output shaft of the servo motor 15. A rotating rod 17 is fixedly sleeved on the outer surface of the round shaft 16. The operator starts the servo motor 15, which causes the round shaft 16 to rotate, thereby causing the round shaft 16 to drive the rotating rod 17 to rotate.

[0025] The rear end of the rotating rod 17 is hinged to a hinge rod 18, and the inner wall of the other end of the hinge rod 18 is movably sleeved with the outer surface of the vertical rod 4. When the rotating rod 17 rotates, it will push the vertical rod 4 to move to the left under the limiting action of the limiting rod 13 and the limiting block 14 through the hinge rod 18.

[0026] The inner wall of the box 1 is movably fitted with a collection box 23. A support frame 19 is fixedly installed on the rear side of the top of the box 1. A pneumatic cylinder 20 is fixedly installed on the top of the support frame 19. The bottom of the pneumatic cylinder 20 passes through the support frame 19 and is movably sleeved with the inner wall of the support frame 19. A punch 21 is fixedly connected to the bottom end of the pneumatic cylinder 20. When the operator starts the pneumatic cylinder 20, the pneumatic cylinder 20 can drive the punch 21 to move downward, so that the punch 21 can punch the disc. The waste material punched out will fall into the collection box 23 through the round hole in the center of the lower mold 2.

[0027] The punch 21 has slide rods 22 fixedly installed on both the left and right sides of its top. The top of the slide rods 22 extends to the top of the support frame 19 and is movably connected to the inner wall of the support frame 19. By setting the slide rods 22, the punch 21 can be more stable when it rises or falls.

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

[0029] When using the device, the operator first places the disc inside the sleeve 6, then starts the servo motor 15, causing the shaft 16 to rotate the rotating rod 17. This causes the hinge rod 18 to push the vertical rod 4 to move to the left under the limit of the limit block 14 and the limit rod 13. This causes the vertical rod 4 to move the sleeve 6 to the left through the connecting plate 5, so that the sleeve 6 moves the disc to the top of the lower mold 2. At this time, the pneumatic cylinder 20 is activated, which will drive the punch 21 to descend, thereby stamping the disc into a pad.

[0030] Then the servo motor 15 continues to start, causing the sleeve 6 to drive the washer to continue moving to the left. When the left side of the sleeve 6 contacts the outer surface of the protrusion 11, it will squeeze and push the protrusion 11 upward, causing the spring 9 to be compressed. As the sleeve 6 moves to the left, the protrusion 11 will move to the top of the washer, and then, under the elastic recovery action of the spring 9, it will push the protrusion 11 downward, causing the protrusion 11 to push the washer inside the sleeve 6 downward, pushing the washer out of the sleeve 6, thereby demolding the washer stuck inside the sleeve 6, which is convenient for the operator to use.
