Description

Technical Field

[0001] This invention relates to the technical field of cutting openings in the sidewall of a rubber ring, and in particular to a device for cutting openings in a rubber ring. Background Technology

[0002] The structure of rubber ring 1 produced in a certain workshop is as follows: Figures 1-3 As shown, a central hole 2 is provided in the center of the rubber ring 1, and the wall thickness of the rubber ring 1 is 1 cm. When a batch of such rings is produced... Figures 1-2 Following the rubber ring 1 shown, the process requires that an opening 3, communicating with the central hole 2, be cut on one side wall of each rubber ring 1, as shown. Figures 4-6 The diagram shows a schematic of a rubber ring 1 with an opening 3 cut into it.

[0003] The method by which the workers in the workshop cut openings 3 on one side wall of each rubber ring 1 is as follows:

[0004] S1. The worker takes out a piece from the material basket. Figures 1-3 The rubber ring 1 shown is placed flat on the machine table.

[0005] S2. The worker uses the thumb of his left hand to press down on rubber ring 1, pressing in the direction shown in the image. Figure 7 As shown by the middle arrow, the worker then uses a cutter held in their right hand to cut one side wall of the rubber ring 1 from top to bottom, thus ultimately creating an opening 3 on one side wall of the rubber ring 1. The structure of the rubber ring 1 with the opening 3 is as follows. Figures 4-6 As shown;

[0006] S3. The worker repeats steps S1 to S2 multiple times to cut an opening 3 on each rubber ring 1.

[0007] However, although the method used in the workshop can cut an opening 3 in the rubber ring 1, the following technical defects still emerge in actual operation:

[0008] I. In step S2, the worker needs to press down the rubber ring 1 with his thumb and then manually cut the rubber ring 1 with a cutter in order to cut an opening 3 on the side wall of the rubber ring 1. The entire operation is done manually by the worker, which not only increases the worker's workload, but also takes a long time to cut an opening 3 on a rubber ring 1, thus reducing the efficiency of cutting an opening 3 on the rubber ring 1.

[0009] II. The number of rubber rings 1 to be cut in the workshop every day is as high as 200. However, the workers can only cut the openings 3 on the rubber rings 1 one by one, which makes it take a long time to cut the openings 3 on all the rubber rings 1, thus further reducing the efficiency of cutting the openings 3 on the rubber rings 1.

[0010] Therefore, there is an urgent need for a device that can greatly reduce the workload of workers and greatly improve the efficiency of cutting openings on rubber rings. Utility Model Content

[0011] The purpose of this invention is to overcome the shortcomings of the prior art and provide a device for cutting openings on rubber rings that greatly reduces the labor intensity of workers and greatly improves the efficiency of cutting openings on rubber rings.

[0012] The purpose of this utility model is achieved through the following technical solution: a device for cutting an opening in a rubber ring, comprising a worktable, on which two mounting components for mounting the rubber ring are provided. The mounting component on the left side includes a pad fixed to the worktable surface. A through groove is formed on the top surface of the pad, penetrating its left and right ends. A positioning post extending outside the through groove is fixed in the bottom of the groove. The diameter of the positioning post is equal to the diameter of the central hole of the rubber ring. A strip groove is formed on the surface of the positioning post along its axial direction. The lower end of the strip groove is...

[0013] A lifting cylinder is fixed on the workbench surface between two mounting components. A channel steel is fixed at the top of the piston rod of the lifting cylinder. Pressure plates are fixed on the left and right outer walls of the channel steel. U-shaped grooves are opened on the outer edges of the two pressure plates. The two U-shaped grooves are located directly above the positioning posts of the two mounting components.

[0014] On the top surface of the channel steel and at its left and right ends, there are connecting plates extending outside the pressure plate. On the top surface of the extension ends of the two connecting plates, there are cutting cylinders. The piston rod of the cutting cylinder passes through the connecting plate downwards, and a horizontally arranged cutter is welded on the extension end. The cutter is located directly above the U-shaped groove of the pressure plate.

[0015] Multiple support legs, which are fixed to the ground, are mounted on the bottom surface of the workbench.

[0016] A support frame is fixed between the pad block and the workbench surface.

[0017] The longitudinal width of the U-shaped groove of the pressure plate is equal to the diameter of the positioning post.

[0018] The two mounting components are symmetrical about the lifting cylinder.

[0019] The device also includes a controller, which is electrically connected to the lifting cylinder and the cutting cylinder via signal lines.

[0020] This invention has the following advantages: it greatly reduces the workload of workers and greatly improves the efficiency of cutting openings on rubber rings. Attached Figure Description

[0044] The present invention will be further described below with reference to the accompanying drawings. The scope of protection of the present invention is not limited to the following description:

[0045] like Figures 8-13 As shown, a device for cutting openings in a rubber ring includes a worktable 4. Multiple support legs, supported on the ground, are fixed to the bottom surface of the worktable 4. Two mounting components 5 for installing the rubber ring 1 are arranged on the worktable 4. The two mounting components 5 are symmetrical about a lifting cylinder 10. The mounting component 5 on the left side includes a pad 6 fixed to the worktable 4. A support frame 17 is fixed between the pad 6 and the worktable 4. A through groove 7 penetrating the left and right ends is opened on the top surface of the pad 6. A positioning post 8 extending outside the through groove 7 is fixed in the bottom of the groove 7. The diameter of the positioning post 8 is equal to the diameter of the central hole 2 of the rubber ring 1. A strip groove 9 arranged axially is opened on the surface of the positioning post 8. The lower end of the strip groove 9...

[0046] A lifting cylinder 10 is fixed on the workbench 4 between two mounting components 5. A channel steel 11 is fixed at the top of the piston rod of the lifting cylinder 10. Pressure plates 12 are fixed on the left and right outer walls of the channel steel 11. U-shaped grooves 13 are opened on the outer edges of the two pressure plates 12. The two U-shaped grooves 13 are respectively located directly above the positioning posts 8 of the two mounting components 5. The longitudinal width of the U-shaped grooves 13 of the pressure plates 12 is equal to the diameter of the positioning posts 8.

[0047] On the top surface of the channel steel 11 and at its left and right ends, there are connecting plates 14 extending outside the pressure plate 12. On the top surface of the extension ends of the two connecting plates 14, there are cutting cylinders 15. The piston rod of the cutting cylinder 15 passes through the connecting plate 14 downward, and a horizontally arranged cutter 16 is welded on the extension end. The cutter 16 is located directly above the U-shaped groove 13 of the pressure plate 12.

[0048] The device also includes a controller, which is electrically connected to the lifting cylinder 10 and the cutting cylinder 15 via a signal line. The worker can control the extension or retraction of the piston rod of the lifting cylinder 10 and the cutting cylinder 15 through the controller, thereby facilitating the worker's operation.

[0049] The method by which the worker uses the device to cut an opening 3 on one side wall of the rubber ring 1 is as follows:

[0050] S1. Installation of the first batch of rubber rings 1: Workers remove five as shown in the image. Figures 1-3 As shown, five rubber rings 1 are sequentially fitted onto the positioning post 8 of the mounting assembly 5 on the left side from top to bottom, thus achieving the installation of the first batch of rubber rings 1. Figure 14 As shown, at this time, five rubber rings 1 are stacked sequentially on the top surface of the pad block 6, and the rubber rings 1 are directly above the pressure plate 12 of the left mounting component 5.

[0051] S2, Installation of the second batch of rubber rings 1: The workers removed the other five... Figures 1-3 As shown, five rubber rings 1 are sequentially fitted onto the positioning post 8 of the mounting assembly 5 on the right side from top to bottom, thus achieving the installation of the second batch of rubber rings 1. Figure 15 As shown;

[0052] S3. Fixing of Rubber Ring 1: The piston rod of the lifting cylinder 10 retracts downwards, causing the channel steel 11 to move downwards. The channel steel 11 then moves the pressure plate 12, cutting cylinder 15, and cutter 16 downwards simultaneously. The pressure plate 12 moves towards the rubber ring 1. When the piston rod of the lifting cylinder 10 is fully retracted, the U-shaped groove 13 of the pressure plate 12 fits over the outside of the positioning post 8, pressing down all five rubber rings 1, thus fixing the rubber ring 1. Figure 16 As shown;

[0053] S4. Control the piston rods of the two cutting cylinders 15 to extend downwards. The piston rods drive the cutter 16 to move downwards. The cutter 16 first enters the U-shaped groove 13 of the pressure plate 12, such as... Figure 17 As shown, as the cutter 16 continues to move downwards, it gradually cuts the sidewalls of the five rubber rings 1. When the cutter 16 enters the through groove 7 of the pad block 6, as... Figure 18 As shown, this ultimately resulted in openings 3 being cut into the sidewalls of all five rubber rings 1;

[0054] As can be seen from steps S1 to S4, the five rubber rings 1 are first stacked on the top surface of the pad block 6, and then the piston rod of the lifting cylinder 10 is controlled to retract downwards to fix the rubber rings 1 through the pressure plate 12; then the piston rod of the cutting cylinder 15 is controlled to extend downwards to cut all five rubber rings 1 installed on the positioning post 8 through the cutter 16, so that openings 3 are cut on the side walls of all ten rubber rings 1.

[0055] Therefore, this device eliminates the need for workers to press down the rubber ring 1 with their thumbs or to manually cut the rubber ring 1 with the cutter 16 to create an opening 3 on the side wall of the rubber ring 1. Instead, it can quickly create an opening 3 on the side wall of the rubber ring 1 through the coordinated operation of the mounting component 5, the lifting cylinder 10, and the cutting cylinder 15. This not only greatly reduces the workload of workers but also enables the opening 3 to be created on the rubber ring 1 in a short time, thereby greatly improving the efficiency of creating an opening 3 on the rubber ring 1.

[0056] S5. Remove the rubber ring 1 with the opening 3. The specific operation steps are as follows:

[0057] S51, control the piston rod of the cutting cylinder 15 to retract upward, the piston rod drives the cutter 16 to move upward; then control the piston rod of the lifting cylinder 10 to extend upward, the piston rod drives the channel steel 11 to move upward, the channel steel 11 drives the pressure plate 12, the cutting cylinder 15 and the cutter 16 to reset.

[0058] S52. The worker removes the rubber ring 1 with the opening 3 cut from the positioning post 8, in the following direction: Figure 18 As shown by the middle arrow, ten rubber rings 1 with openings 3 are obtained at once. The structure of the rubber rings 1 with openings 3 is as follows. Figures 4-6 As shown;

[0059] S6. The worker repeats steps S1 to S5 multiple times to cut openings 3 on the side walls of multiple rubber rings 1.

[0060] As can be seen from steps S1 to S6, by simply coordinating the installation component 5, the lifting cylinder 10 and the cutting cylinder 15, openings 3 can be cut on the side walls of all ten rubber rings 1 at once, eliminating the need for workers to cut the rubber rings 1 one by one. This allows all 200 rubber rings 1 in the workshop to have their openings 3 cut in one day, thereby further improving the efficiency of cutting openings 3 on the rubber rings 1.

[0061] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
