A rubber punching device for producing sealing rings

Abstract

This utility model discloses a rubber punching device for producing sealing rings, relating to the field of sealing ring production technology. The utility model includes a housing. By pulling the punching component, it moves to the bottom of the drive component. Rubber is then placed on the top of the punching component, and the punching component is pushed back to its original position. The drive component then moves the punching component mounted on its output end, causing the transmission component mounted on its bottom end to move as well. This causes the transmission component to rotate during the engagement process, which in turn causes a limiting component mounted on its outer surface to rotate. The limiting component converts rotation into movement, allowing it to insert into the punching component and thus limit the punching component, preventing slippage during rubber punching. This facilitates the loading and unloading of rubber and improves the safety of the rubber punching device for sealing ring production.

Description

Technical Field

[0001] This utility model belongs to the field of sealing ring production technology, and specifically relates to a rubber punching device for sealing ring production. Background Technology

[0002] In the production of sealing rings, rubber punching is an essential and critical process. Its core purpose is to efficiently and accurately cut the mixed rubber sheets or rolls into preforms of specific shapes and sizes to prepare for subsequent vulcanization molding.

[0003] In existing technology, the entire piece of rubber is usually placed inside the die, and then the die-cutting device is activated to drive the die-cutting process to cut the rubber. However, the die-cutting device is fixed inside the die-cutting device, which means that it needs to go deep into the die-cutting device during the feeding process. This is not convenient for feeding the rubber, and if there is accidental contact during the feeding process, it can easily cause injury to the workers, thus reducing its safety. Utility Model Content

[0004] To address the issues that the blanking die is fixedly installed inside the blanking device, requiring it to penetrate deep into the device during the feeding process, which is inconvenient for feeding rubber and could easily cause injury to workers if accidentally touched during feeding, thus reducing safety, this utility model proposes a rubber blanking device for producing sealing rings to overcome the aforementioned technical problems in existing related technologies.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a rubber punching device for producing sealing rings, comprising a housing:

[0007] The housing is respectively equipped with a drive assembly, a punching assembly, a transmission assembly, a limit assembly, and a reset assembly;

[0008] The drive assembly has its output end fixedly installed at the top of the punching assembly so that the drive assembly drives the punching assembly to punch the rubber.

[0009] The transmission component is fixedly installed at its top end to the bottom end of the blanking component so that the transmission component is driven to rotate when the blanking component moves.

[0010] The limiting component is fixedly installed inside the transmission component on the outer surface, so that the limiting component is driven to move when the transmission component rotates, so as to limit the blanking component.

[0011] A reset component is fixedly connected on one side to a limit component on the other side, so that the reset component drives the limit component to reset.

[0012] Furthermore, the drive assembly includes a mounting plate, the bottom end of which is fixedly mounted to the top end of the housing. A limit shaft is fixedly connected to the top end of the mounting plate, a support plate is fixedly mounted to the top end of the limit shaft, and a cylinder is fixedly mounted to the top end of the support plate.

[0013] Furthermore, the blanking assembly includes a limiting strip and an upper die. The bottom end of the limiting strip is fixedly installed to the top end of the mounting plate. An mounting platform is slidably provided inside the limiting strip, and a lower die is fixedly installed at the top end of the mounting platform.

[0014] The top of the upper mold is fixedly installed with the telescopic end of the cylinder, and the interior of the upper mold is slidably set with the outer surface of the limiting shaft.

[0015] Furthermore, the transmission assembly includes a support cylinder and a drive shaft, the outer surface of the support cylinder is rotatably disposed with the interior of the mounting plate, and an arc-shaped groove is formed inside the support cylinder;

[0016] The top end of the drive shaft is fixedly installed to the bottom end of the upper mold, and a guide rod is fixedly connected to the outer surface of the drive shaft.

[0017] Furthermore, the limiting component includes a limiting block, the bottom end of which is fixedly connected to the top end of the mounting plate, a rack is slidably arranged inside the limiting block, a gear is meshed with the surface of the rack, and the inside of the gear is fixedly installed to the outer surface of the support cylinder.

[0018] Furthermore, the limiting component also includes a limiting groove, which is respectively opened inside the limiting strip and the mounting platform. A positioning strip is slidably arranged inside the limiting groove, and one end of the positioning strip is fixedly connected to one end of the rack.

[0019] Furthermore, the reset assembly includes a first connecting plate, one side of which is fixedly connected to one side of the positioning strip, a tension spring fixedly connected to one side of the first connecting plate, a second connecting plate fixedly connected to one end of the tension spring, and one side of the second connecting plate fixedly connected to one side of the limiting block.

[0020] This utility model has the following beneficial effects:

[0021] 1. This utility model involves pulling the punching assembly to move it to the bottom of the drive assembly, placing the rubber on top of the punching assembly, and then pushing the punching assembly to reset. The drive assembly is then activated to move the punching assembly installed at the output end, causing the transmission assembly installed at the bottom to move during the movement. This causes the transmission assembly to rotate during the engagement process, which in turn causes the limiting assembly installed on the outer surface to rotate. The limiting assembly converts the rotation into movement, allowing it to insert into the punching assembly and thus limit the punching assembly, preventing slippage during the rubber punching process. This facilitates the loading and unloading of rubber and improves the safety of the rubber punching device for producing sealing rings.

[0022] 2. This utility model allows the mounting platform to be moved along the direction of the limiting strip by pulling the mounting platform, thereby moving the mounting platform to the outside of the upper mold. At the same time, when the mounting platform moves, it can drive the lower mold mounted at the top to move, which facilitates the loading and unloading of materials into the lower mold. After the loading is completed, the mounting platform is pushed to drive the lower mold to reset, and then the cylinder is started to drive the upper mold mounted at the telescopic end to move downward, so that the upper mold and the lower mold can cooperate to perform punching processing on rubber more conveniently.

[0023] 3. This utility model uses a support cylinder to drive the gear mounted on the outer surface to rotate, so that the gear drives the rack that is meshed with the surface to move. Since the outer surface of the rack is slidably set with the inside of the limiting block, and the bottom end of the limiting block is fixedly connected to the top end of the mounting plate, when the rack moves, it can drive the positioning strip fixed at one end to move along the direction of the limiting block. Since one end of the positioning strip has a wedge surface, it is convenient for the positioning strip to enter the limiting groove opened inside the mounting platform when it moves, so that the positioning strip restricts the position of the mounting platform, thereby improving the stability of the mounting platform.

[0024] Of course, any product implementing this utility model does not necessarily need to achieve all of the above advantages at the same time. Attached Figure Description

[0034] The technical solutions of the utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the utility model.

[0035] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.

[0036] Please see Figures 1-6 As shown, this utility model is a rubber punching device for producing sealing rings, including a housing 1:

[0037] The housing 1 is respectively provided with a drive assembly 2, a punching assembly 3, a transmission assembly 4, a limit assembly 5, and a reset assembly 6;

[0038] The drive assembly 2 is fixedly installed at the top of the punching assembly 3 so that the drive assembly 2 drives the punching assembly 3 to punch the rubber.

[0039] The transmission component 4 is fixedly installed at its top end to the bottom end of the punching component 3 so that the transmission component 4 is driven to rotate when the punching component 3 moves.

[0040] The limiting component 5 is fixedly installed inside the transmission component 4 on the outer surface, so that when the transmission component 4 rotates, the limiting component 5 is driven to move, so as to limit the blanking component 3.

[0041] The reset component 6 is fixedly connected on one side to the limit component 5, so that the reset component 6 drives the limit component 5 to reset.

[0042] In use, by pulling the punching assembly 3, it is moved to the bottom of the drive assembly 2. Then, the rubber is placed on the top of the punching assembly 3, and the punching assembly 3 is pushed to reset. The drive assembly 2 is activated to drive the punching assembly 3 installed at the output end to move, so that the transmission assembly 4 installed at the bottom moves during the movement. This causes the transmission assembly 4 to rotate during the engagement process, which in turn causes the limiting assembly 5 installed on the outer surface to rotate. The limiting assembly 5 converts the rotation into movement, so that it is inserted into the interior of the punching assembly 3, thereby limiting the punching assembly 3 and preventing slippage during the rubber punching process. When the processing is completed, the punching assembly 3 moves upward with the drive assembly 2, which causes the transmission assembly 4 to move upward, thereby causing the limiting assembly 5 to lose its rotational force. This allows the reset assembly 6 to drive the limiting assembly 5 to reset, so that the limiting assembly 5 releases its limitation on the punching assembly 3, so that the material can be loaded and unloaded again at the top of the punching assembly 3.

[0043] This invention involves pulling the punching assembly 3 to move it to the bottom of the drive assembly 2, placing the rubber on top of the punching assembly 3, and then pushing the punching assembly 3 to reset. The drive assembly 2 then moves the punching assembly 3 installed at the output end, causing the transmission assembly 4 installed at the bottom to move as well. This causes the transmission assembly 4 to rotate during the engagement process, which in turn causes the limiting assembly 5 installed on its outer surface to rotate. The limiting assembly 5 converts rotation into movement, allowing it to insert into the punching assembly 3 and thus limit the punching assembly 3, preventing slippage during the rubber punching process. This facilitates the loading and unloading of rubber and improves the safety of the rubber punching device for producing sealing rings.

[0044] In one embodiment, the drive assembly 2 includes a mounting plate 201, the bottom end of which is fixedly mounted to the top end of the housing 1. A limiting shaft 202 is fixedly connected to the top end of the mounting plate 201. A support plate 203 is fixedly mounted on the top end of the limiting shaft 202. A cylinder 204 is fixedly mounted on the top end of the support plate 203.

[0045] The mounting plate 201 is designed to work with the top-fixed limiting shaft 202 to support the support plate 203. The limiting shaft 202 is provided in four symmetrical sets, which can support the four corners of the support plate 203, thereby improving the stability of the cylinder 204 mounted at the top during operation.

[0046] In one embodiment, for the above-mentioned blanking assembly 3, the blanking assembly 3 includes a limiting strip 301 and an upper die 302. The bottom end of the limiting strip 301 is fixedly installed with the top end of the mounting plate 201. An mounting platform 303 is slidably arranged inside the limiting strip 301. A lower die 304 is fixedly installed at the top end of the mounting platform 303.

[0047] The top of the upper mold 302 is fixedly installed with the telescopic end of the cylinder 204, and the interior of the upper mold 302 is slidably set with the outer surface of the limiting shaft 202.

[0048] By pulling the mounting platform 303, it can be moved along the direction of the limiting strip 301, thereby moving the mounting platform 303 to the outside of the upper mold 302. At the same time, when the mounting platform 303 moves, it can drive the lower mold 304 mounted at the top to move, thereby facilitating the loading and unloading of materials into the lower mold 304. After the loading is completed, the mounting platform 303 is pushed to drive the lower mold 304 to reset. Then, the cylinder 204 is activated to drive the upper mold 302 mounted at the telescopic end to move downward, so that the upper mold 302 and the lower mold 304 can cooperate to perform punching processing on the rubber more conveniently.

[0049] In one embodiment, the transmission assembly 4 includes a support cylinder 401 and a drive shaft 402. The outer surface of the support cylinder 401 is rotatably disposed with the interior of the mounting plate 201, and an arc groove 403 is provided inside the support cylinder 401.

[0050] The top end of the drive shaft 402 is fixedly installed with the bottom end of the upper mold 302, and a guide rod 404 is fixedly connected to the outer surface of the drive shaft 402.

[0051] When the upper mold 302 moves downward, it can drive the drive shaft 402 mounted at the bottom to move, so that the drive shaft 402 drives the guide rod 404 fixed on the outer surface to move. Since the vertical position of the guide rod 404 corresponds to the opening position of the arc groove 403, when the guide rod 404 moves downward, it can enter from the opening position of the arc groove 403 and rotate at a fixed angle with the arc drive support cylinder 401 opened in the arc groove 403.

[0052] In one embodiment, the limiting component 5 includes a limiting block 501, the bottom end of the limiting block 501 is fixedly connected to the top end of the mounting plate 201, a rack 502 is slidably disposed inside the limiting block 501, a gear 503 is meshed with the surface of the rack 502, and the inside of the gear 503 is fixedly installed with the outer surface of the support cylinder 401.

[0053] The limiting component 5 also includes a limiting groove 504, which is respectively opened inside the limiting strip 301 and the mounting platform 303. A positioning strip 505 is slidably arranged inside the limiting groove 504, and one end of the positioning strip 505 is fixedly connected to one end of the rack 502.

[0054] When the support cylinder 401 rotates, it drives the gear 503 mounted on its outer surface to rotate, causing the gear 503 to move the rack 502 that is surface-engaged. Since the outer surface of the rack 502 is slidably disposed with the inside of the limiting block 501, and the bottom end of the limiting block 501 is fixedly connected to the top end of the mounting plate 201, when the rack 502 moves, it can drive the positioning strip 505 fixed at one end to move along the direction of the limiting block 501. Since one end of the positioning strip 505 has a wedge surface, it is convenient for the positioning strip 505 to enter the limiting groove 504 opened inside the mounting platform 303 when it moves, so that the positioning strip 505 restricts the position of the mounting platform 303, thereby improving the stability of the mounting platform 303.

[0055] In one embodiment, the reset component 6 includes a first connecting plate 601, one side of which is fixedly connected to one side of the positioning strip 505, a tension spring 602 is fixedly connected to one side of the first connecting plate 601, one end of the tension spring 602 is fixedly connected to a second connecting plate 603, and one side of the second connecting plate 603 is fixedly connected to one side of the limiting block 501.

[0056] When the positioning bar 505 moves, it can drive the first connecting plate 601 fixed on one side to move, so that the first connecting plate 601 drives the tension spring 602 fixed on one side to stretch. Thus, when the positioning bar 505 loses the pushing force of the rack 502, the tension spring 602 can reset, and can work with the first connecting plate 601 to drive the positioning bar 505 to reset and move. This allows the positioning bar 505 to work with the rack 502 to drive the gear 503 to reset and rotate, so as to drive the support cylinder 401 installed inside the gear 503 to reset, which is more convenient.

[0057] Through the above technical solution, 1. By pulling the punching component 3, it is moved to the bottom range of the drive component 2. Then, the rubber is placed on the top of the punching component 3. Then, the punching component 3 is pushed to reset. By starting the drive component 2, the punching component 3 installed at the output end is moved, so that the transmission component 4 installed at the bottom end is moved during the movement. Thus, the transmission component 4 rotates during the engagement process, which in turn drives the limiting component 5 installed on the outer surface to rotate. The limiting component 5 converts the rotation into movement, so that it is inserted into the interior of the punching component 3, thereby limiting the punching component 3 and preventing slippage during the rubber punching process. This facilitates the loading and unloading of rubber and improves the safety of the rubber punching device for producing sealing rings.

[0058] 2. By pulling the mounting table 303, it can be moved along the direction of the limit strip 301, thereby moving the mounting table 303 to the outside of the upper mold 302. At the same time, when the mounting table 303 moves, it can drive the lower mold 304 mounted at the top to move, thereby facilitating the loading and unloading of materials into the lower mold 304. After the loading is completed, push the mounting table 303 to drive the lower mold 304 to reset, and then start the cylinder 204 to drive the upper mold 302 mounted at the telescopic end to move downward, so that the upper mold 302 and the lower mold 304 can cooperate to perform punching processing on rubber more conveniently.

[0059] 3. The gear 503 mounted on the outer surface is rotated by the support cylinder 401, so that the gear 503 drives the rack 502, which is surface-engaged, to move. Since the outer surface of the rack 502 is slidably set with the inside of the limiting block 501, and the bottom end of the limiting block 501 is fixedly connected to the top end of the mounting plate 201, when the rack 502 moves, it can drive the positioning strip 505 fixed at one end to move along the direction of the limiting block 501. Since one end of the positioning strip 505 has a wedge surface, it is convenient for the positioning strip 505 to enter the limiting groove 504 opened inside the mounting platform 303 when it moves, so that the positioning strip 505 restricts the position of the mounting platform 303, thereby improving the stability of the mounting platform 303.
