Description

Technical Field

[0001] This application relates to the field of wire drawing equipment, and more particularly to an automatic wire drawing device. Background Technology

[0002] Surface brushing is a surface treatment method that creates lines on the surface of a workpiece through grinding, achieving a decorative effect. Because surface brushing can bring out the texture of metal materials, it has been widely used.

[0003] However, existing automatic wire drawing machines are usually used to process sheet-like workpieces. When processing tubular workpieces, they cannot be flexibly adapted to tubular workpieces of different diameters, which reduces the flexibility and adaptability of automatic wire drawing equipment and reduces the efficiency of processing tubular workpieces with different gripping forces. Utility Model Content

[0004] To address the aforementioned technical problems, this application provides an automatic wire drawing device.

[0005] This application provides an automatic wire drawing device, which adopts the following technical solution:

[0006] An automatic wire drawing device includes a processing platform, a processing hole in the center of the processing platform, a wire drawing mechanism, a lifting mechanism, and a clamping mechanism for clamping tubular workpieces on the processing platform. The wire drawing mechanism includes a plurality of first cylinders and a plurality of wire drawing blocks on the processing platform. The wire drawing blocks are detachably connected to the telescopic ends of the first cylinders. The plurality of wire drawing blocks are arranged in a circumferential array outside the processing hole. The side of the wire drawing block away from the first cylinder has an arc-shaped structure and a wire drawing groove. The clamping mechanism includes a base plate connected to the lifting mechanism, an adjustment component on the base plate, and at least three inner clamping blocks connected to the adjustment component. The plurality of inner clamping blocks are arranged in a circumferential array.

[0007] By adopting the above technical solution, the wire drawing blocks in the wire drawing mechanism are arranged in a circumferential array. The clamping mechanism extends into the tubular workpiece to clamp it, and the lifting mechanism drives the clamping mechanism and the tubular workpiece to rise and fall, so that the outer surface of the tubular workpiece slides into contact with the wire drawing blocks, thereby performing surface wire drawing on the tubular workpiece. The wire drawing blocks in the wire drawing mechanism are detachably connected to the telescopic end of the first cylinder, allowing the wire drawing blocks to be quickly replaced as needed, thus adapting to tubular workpieces of different diameters for surface wire drawing. At the same time, the multiple inner clamping blocks in the clamping mechanism are arranged in a circumferential array, which can flexibly adjust their positions to clamp tubular workpieces of different diameters, improving the equipment's adaptability to workpieces of various specifications. This structure not only enhances the flexibility of the automatic wire drawing equipment but also significantly improves processing efficiency.

[0008] Preferably, the adjustment assembly includes a housing disposed on the base plate, a cover plate disposed at one end of the housing away from the base plate, a plurality of fixing blocks disposed on the cover plate, a mounting groove formed on the fixing block, a sliding block slidably connected to the mounting groove, a first toothed plate disposed on the top of the fixing block, and a second toothed plate disposed on the bottom of the inner clamping block. The inner clamping block is detachably connected to the sliding block by bolts, and the first toothed plate and the second toothed plate are engaged. Both the mounting groove and the sliding block are T-shaped structures.

[0009] By adopting the above technical solution, the structural design of the adjusting component enables precise adjustment of the inner clamping block's position. Specifically, the housing and cover plate provide a stable support frame for the entire adjusting component. The engagement of the mounting groove on the fixed block and the sliding block allows the inner clamping block to move along a predetermined trajectory, while the meshing connection between the first and second toothed plates further ensures the stability of the inner clamping block's position locking. This design allows the clamping mechanism to flexibly adapt to tubular workpieces of different diameters, significantly improving the adaptability of the automatic wire drawing equipment. Simultaneously, the T-shaped mounting groove and sliding block enhance the system's reliability and durability, effectively preventing the risk of disengagement.

[0010] Preferably, an elastic protective pad is provided at the end of the inner clamping block away from the center of the cover plate.

[0011] By adopting the above technical solution, an elastic protective pad is set at the end of the inner clamping block away from the center of the cover plate, which can reduce damage to the surface of the workpiece when clamping tubular workpieces, improve the safety and stability during the clamping process, and extend the service life of the inner clamping block.

[0012] Preferably, the wire drawing block is provided with a connecting groove, and the telescopic end of the first cylinder is provided with a connecting slider. The connecting slider is slidably connected to the connecting groove, and the connecting slider is detachably connected to the wire drawing block by bolts.

[0013] By adopting the above technical solution, a connecting groove is opened on the wire drawing block, which slides to connect with the connecting slider at the telescopic end of the first cylinder. This enables rapid assembly and positioning between the wire drawing block and the first cylinder. Simultaneously, bolts further secure the connecting slider and the wire drawing block, ensuring the reliability of their connection. This design not only facilitates the replacement of wire drawing blocks of different specifications to accommodate tubular workpieces of different diameters but also improves the convenience of equipment maintenance and adjustment, thereby enhancing the overall flexibility and working efficiency of the automatic wire drawing equipment.

[0014] Preferably, the processing platform is provided with a limiting mechanism, which includes a mounting base on the processing platform and a limiting block on the mounting base. The limiting block has a limiting groove, and the tubular workpiece is slidably connected to the limiting groove.

[0015] By adopting the above technical solution, the limiting mechanism can effectively restrict the position of the tubular workpiece, ensuring its stability during processing. Specifically, the combined use of the mounting base and the limiting block, as well as the sliding connection between the limiting groove and the tubular workpiece, can prevent the workpiece from shifting or shaking during the wire drawing operation, thereby improving processing accuracy and ensuring the consistency of surface wire drawing quality.

[0016] Preferably, the lifting mechanism includes multiple connecting rods connected to the bottom of the processing platform, a mounting plate disposed at one end of the connecting rods away from the processing platform, a second cylinder disposed in the center of the mounting plate, and a support plate disposed at the telescopic end of the second cylinder, the support plate being connected to the base plate.

[0017] By adopting the above technical solution, the vertical position adjustment of the clamping mechanism is achieved. Specifically, the connecting rod connects the processing platform to the mounting plate, ensuring the stability of the entire structure; the extension and retraction of the second cylinder drives the support plate to move up and down, thereby driving the base plate and the clamping mechanism on it to rise and fall synchronously. This design allows the clamping mechanism to accurately adapt to processing requirements at different heights, enhancing the flexibility and applicability of the equipment.

[0018] Preferably, the support plate has a plurality of guide rods at one end away from the base plate, and the mounting plate has a plurality of guide holes, with the guide rods slidably connected to the guide holes.

[0019] By adopting the above technical solution, the cooperation between the guide rod and the guide hole can effectively improve the stability of the support plate during the lifting process, preventing the shaking caused by the second cylinder drive from affecting the processing accuracy. At the same time, the structural design is simple and reliable, easy to manufacture and assemble, and ensures the smooth operation of the entire lifting mechanism, thereby improving the overall performance of the automatic wire drawing equipment.

[0020] Preferably, a guide sleeve is provided in the guide hole, and the guide rod is slidably connected to the guide sleeve.

[0021] By adopting the above technical solution, the sliding connection between the guide rod and the guide sleeve increases the contact area between the guide rod and the support plate, improves the smoothness of movement, enhances the guiding accuracy, ensures the stability of the support plate during the lifting process, and thus improves the working reliability of the entire automatic wire drawing equipment.

[0022] Preferably, a limiting sleeve is provided at the end of the guide rod away from the support rod.

[0023] By adopting the above technical solution, the limiting sleeve can effectively prevent the guide rod from dislodging from the guide hole, ensure the stability of the support plate during the lifting process, and avoid equipment failure or safety hazards caused by the loosening of the guide rod. This design further improves the overall reliability of the automatic wire drawing equipment.

[0024] In summary, this application has the following beneficial technical effects:

[0025] 1. The internal clamping block can be flexibly adjusted in position through the adjustment component, thereby adapting to tubular workpieces of different diameters. This solves the problem of insufficient flexibility caused by the fixed clamps in the existing technology and significantly improves the equipment's compatibility with different types of workpieces.

[0026] 2. The wire drawing block and the telescopic end of the first cylinder are detachably connected, which makes it easy to replace different wire drawing blocks according to actual needs, and realizes the effective processing of tubular workpieces of different diameters, further enhancing the applicability and processing efficiency of the equipment;

[0027] 3. Multiple inner clamping blocks are arranged in a circumferential array and are combined with elastic protective pads to ensure the stability and safety of tubular workpieces during the clamping process, while reducing the risk of workpiece surface damage and improving processing quality.
