Description

Technical Field

[0001] This utility model belongs to the field of mechanical processing technology, and specifically relates to a hole forming device for processing rubber strips. Background Technology

[0002] Currently, in the production of some roller components (such as secondary transfer rollers for copiers), it is necessary to machine a central hole in the foamed rubber strip for mounting the central shaft. When processing with traditional machine tools, a clamping mechanism is used to clamp and position the rubber strip from the circumference, and then a drill bit is used to drill a hole from one end of the rubber strip to the other end.

[0003] However, in actual processing, because the rubber strip is a flexible material, the force generated when the drill bit of a traditional machine tool drills into the rubber strip can easily cause the rubber strip to twist and deform, which in turn leads to deviations in the forming path of the hole and affects the subsequent assembly accuracy. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide an improved hole forming device for processing rubber strips.

[0005] To solve the above technical problems, the present invention adopts the following technical solution: A hole-forming device for processing rubber strips includes a base, a compression component, and a drilling component. The base has a cavity inside. The compression component has a compression end movably disposed in the cavity. A limiting area is formed between the compression end and the inner wall of the cavity, extending along the length direction of the rubber strip and matching the circumferential contour of the rubber strip. The rubber strip is placed in the limiting area and is circumferentially limited. The compression end is used to compress the rubber strip in the length direction. The drill bit of the drilling component extends into the limiting area and is used to drill a hole along the length direction of the rubber strip based on the compressed rubber strip.

[0006] Preferably, the compression end is movably disposed within the cavity along the length of the rubber strip, and a limiting zone is formed between the compression end face of the compression end, the inner wall of one end of the base, and the side wall of the base. The compression end compresses the rubber strip with the inner wall of one end of the base as a reference. This design is simple and convenient to operate.

[0007] Preferably, in the orthographic projection along the length of the rubber strip, the rubber strip, the compression end face, and the inner wall surface of one end of the base coincide. This ensures that the rubber strip deforms only along its length during compression, which helps improve drilling accuracy.

[0008] Preferably, the compression component includes a cylinder and a controller, wherein the telescopic shaft of the cylinder is inserted into the cavity from the other end of the base and connected to the compression end.

[0009] Preferably, the telescopic shaft extends along the length of the rubber strip, and the centerline of the telescopic shaft coincides with the centerline of the compression end. This ensures that the compressive force generated at the compression end is evenly distributed across the end face of the rubber strip.

[0010] Preferably, the controller is a foot-operated controller for controlling the extension and retraction of the cylinder. Here, foot control facilitates simultaneous handling, compression, and drilling of the rubber strips by production personnel, enabling single-person production operation.

[0011] Preferably, during drilling, the drill bit of the drilling component is inserted into the cavity from one end of the base, and the length of the drill bit inserted into the cavity is equal to the length of the compressed rubber strip. This ensures that the drill bit penetrates the rubber strip to form a hole while avoiding impact with the compressed end.

[0012] Preferably, the centerline of the drill bit coincides with the centerline of the rubber strip. The formed hole is the center hole of the rubber strip.

[0013] Preferably, the base includes a base plate, two end plates spaced side-by-side on the base plate along the length of the rubber strip, side plates correspondingly connected between the opposite sides of the two end plates, and a top plate covering the end plates and side plates. This design is simple and has low manufacturing costs.

[0014] In addition, the cross-section of the rubber strip is rectangular.

[0015] Due to the implementation of the above technical solution, this utility model has the following advantages compared with the prior art: Existing rubber strips are made of flexible material. When a drill bit from a traditional machine tool drills into the rubber strip, the force generated easily causes the rubber strip to twist and deform, leading to deviations in the hole forming path and affecting subsequent assembly accuracy. This application addresses this by comprehensively designing the hole forming device for rubber strip processing, cleverly solving the shortcomings and defects of existing technologies. With this hole forming device, the rubber strip is placed in the cavity of the base, ensuring it is positioned within the limiting area formed by the compression end of the compression component and the inner wall of the cavity to maintain circumferential limiting. Then, the compression end is driven along the length of the rubber strip... The upper movement compresses the rubber strip; finally, the drill bit of the drilling component extends into the limiting area and drills a hole along the length of the rubber strip using the compressed rubber strip as a reference. Therefore, compared with the prior art, this utility model, through the cooperation of the base and the compression component, enables the rubber strip to be compressed along its own length while maintaining circumferential limitation, so as to simultaneously enhance its own strength and shorten the drilling distance. Then, the drilling component drills a hole using the compressed rubber strip as a reference, which greatly reduces the probability of deformation of the rubber strip during the drilling process, effectively improves the forming accuracy of the hole, and improves the product yield. The structure is simple and the operation is convenient. Attached Figure Description

[0022] like Figures 1 to 3 As shown, the hole forming device for processing rubber strips in this embodiment is used to process a central through hole on the rubber strip T, and the hole forming device includes a base 1, a compression component 2 and a drilling component 3.

[0023] Specifically, the base 1 includes a base plate 10, two end plates 11 spaced side-by-side along the length of the rubber strip T on the base plate 1, side plates 12 correspondingly connected between the opposite sides of the two end plates 11, and a top plate 13 that covers the top of the end plates 11 and the side plates 12 and is detachable and installable. The base plate 10, end plates 11, side plates 12, and top plate 13 form a cavity q0. This design is simple and has low manufacturing costs.

[0024] In this embodiment, the cross-section of the rubber strip T is rectangular. Therefore, the cross-section of the cavity q is also a rectangle that matches the rubber strip T, and the length of the cavity q is greater than the length of the rubber strip T in its natural state.

[0025] In this example, the compression component 2 has a compression end d movably disposed in the cavity q. A limiting area q1 is formed between the compression end d and the inner wall of the cavity q0, extending along the length direction of the rubber strip T and matching the circumferential contour of the rubber strip T. The rubber strip T is placed in the limiting area q1 and is limited in the circumferential direction. The compression end d is used to compress the rubber strip T in the length direction.

[0026] In some specific embodiments, the compression end d is movably disposed within the cavity q0 along the length direction of the rubber strip T; and a limiting area q1 is formed between the compression end face of the compression end d, the inner wall of one end of the base 1, and the side wall of the base 1. The compression end d compresses the rubber strip with the inner wall of one end of the base as a reference; in the orthographic projection along the length direction of the rubber strip T, the rubber strip T, the compression end face of the compression end d, and the inner wall surface of one end of the base 1 coincide. Here, ensuring that the rubber strip deforms only in the length direction during compression is beneficial to improving drilling accuracy.

[0027] For ease of implementation, the compression component 2 includes a cylinder 20 and a controller 21. The telescopic shaft 200 of the cylinder 20 is inserted into the cavity q0 from one end of the base 1 and connected to the compression end d. The telescopic shaft 200 extends along the length of the rubber strip T, and the centerline of the telescopic shaft 200 coincides with the centerline of the compression end d. This ensures that the compressive force generated by the compression end is evenly distributed on the end face of the rubber strip.

[0028] Meanwhile, controller 21 is a foot-operated controller for controlling the extension and retraction of cylinder 20. This foot control allows production personnel to simultaneously perform tasks such as picking up, placing, compressing, and drilling rubber strips, enabling single-person production operation.

[0029] In this example, the drill bit t of the drilling component 3 extends into the limiting area q1 and is used to drill a hole along the length of the compressed rubber strip T, using the compressed rubber strip T as a reference. That is to say, after the rubber strip is compressed, its overall strength is improved and its resistance to deformation is enhanced. Moreover, combined with the compression of the rubber strip in the circumferential limiting area along its length, the deformation generated during the drilling process can be further reduced to ensure the forming accuracy of the hole.

[0030] In some specific embodiments, the drilling component 3 uses any conventional drilling equipment, and the drill bit t is also a conventional drill bit suitable for drilling rubber strips. During drilling, the drill bit t of the drilling component 3 is inserted into the cavity q0 (or the limiting area q1) from one end of the base 1, and the length of the drill bit inserted into the cavity q0 is equal to the length of the compressed rubber strip T. Here, it is ensured that the drill bit penetrates the rubber strip to form a hole while avoiding the drill bit hitting the compressed end.

[0031] Furthermore, the centerline of the drill bit t coincides with the centerline of the rubber strip T. The forming hole k is the center hole of the rubber strip T. That is to say, in this embodiment, the centerlines of the drill bit t, the compression end d, the telescopic shaft 200, and the rubber strip T coincide.

[0032] In summary, by employing this hole-forming device, a rubber strip is placed within the cavity of the base, ensuring it remains within the limiting area formed by the compression end of the compression component and the inner wall of the cavity, thus maintaining circumferential limiting. Next, the compression end is driven to move along the length of the rubber strip to compress it. Finally, the drill bit of the drilling component extends into the limiting area and drills a hole along the length of the compressed rubber strip, using the compressed rubber strip as a reference. Therefore, compared to existing technologies, this invention, through the cooperation of the base and the compression component, enables the rubber strip to be compressed along its own length while maintaining circumferential limiting, thereby simultaneously enhancing its strength and shortening the drilling distance. The drilling component uses a compressed rubber strip as a reference for drilling, which greatly reduces the probability of deformation of the rubber strip during drilling, effectively improving the forming accuracy of the hole and increasing the product yield. It has a simple structure and is easy to operate. Secondly, during compression, it ensures that the rubber strip deforms only in the length direction, which is beneficial to improving drilling accuracy. Thirdly, it ensures that the compressive force formed at the compression end is evenly distributed on the end face of the rubber strip. Fourthly, it ensures that the drill bit penetrates the rubber strip to form a hole while avoiding impact on the compression end. Fifthly, it adopts foot control, which allows production personnel to simultaneously pick up, place, compress, and drill the rubber strip, enabling single-person production operation.

[0033] The present utility model has been described in detail above, with the aim of enabling those skilled in the art to understand its contents and implement it. However, this description should not be construed as limiting the scope of protection of the present utility model. All equivalent changes or modifications made in accordance with the spirit and essence of the present utility model should be included within the scope of protection of the present utility model.
