Description

Technical Field

[0001] This utility model relates to the technical field of metal pressing processing, specifically a continuous drawing machine for metal pressing. Background Technology

[0002] A combined drawing machine, also known as a multi-stage drawing machine, is a fully automated metal finishing equipment that integrates uncoiling, drawing, straightening, cutting, polishing, and flaw detection processes. It is mainly used in the production of bars, tubes, profiles, and wires, covering industries such as bright material processing, fasteners, and automotive parts. The equipment consists of functional modules including an uncoiling machine, a pre-straightening device, a drawing main unit, a multi-stage straightener, a hydraulic shearing machine, a polishing machine, and a flaw detection device. Deviations can easily occur during the rotation of the winding drum, causing the metal wire to become entangled on the shaft or chassis, requiring manual intervention.

[0003] Chinese Patent No. CN223070158U discloses a continuous drawing machine for processing ferrous metal pressed products. The continuous drawing machine includes a machine body and a wire feeder disposed on one side of the machine body. The wire feeder has a wire guide at the wire outlet end. The wire guide includes a connecting part connected to the wire feeder and a guiding part connected to the connecting part for guiding the direction of the metal wire.

[0004] In the above solution, the guide part provides guidance for the metal wire, which reduces the tangling of the metal wire. However, it still has the following disadvantages: the guide ring is a fixed size structure, which cannot flexibly adjust the internal space according to the metal wire of different diameters. The metal wire is prone to shaking in the guide ring due to the mismatch between the diameters of the two. Utility Model Content

[0005] The purpose of this invention is to provide a continuous drawing machine for metal pressing products, in order to solve the problem that the guide ring has a fixed size structure, which cannot flexibly adjust the internal space according to metal wires of different diameters, and the metal wires are prone to shaking in the guide ring due to the mismatch between the diameters of the two.

[0006] To achieve the above-mentioned utility model objectives, the present utility model adopts the following technical solution: a continuous drawing machine for metal pressing products, including a load-bearing base, the load-bearing base being disposed on the left side of the continuous drawing machine body, a limiting cylinder being connected to the inside of the load-bearing base by screws, a connecting column being inserted into the inner wall of the limiting cylinder, a placement frame being rotatably disposed at the top of the connecting column, a receiving groove being opened on the inner bottom surface of the placement frame, a bidirectional screw being rotatably disposed inside the placement frame, the bidirectional screw extending into the receiving groove, two clamping blocks being slidably disposed on the inner wall of the placement frame, a connecting block being fixed on the bottom surface of the clamping block, the connecting block being slidably connected in the receiving groove, the connecting block being threadedly connected to the outer wall of the bidirectional screw, a guide frame being disposed on the inner wall of the clamping block, and an arc surface being opened on the inner wall of the guide frame.

[0007] Preferably, the outer wall of the bidirectional screw is threaded with a threaded ring.

[0008] Preferably, the inner wall of the clamping block is fixed with an anti-slip pad, and the anti-slip pad is in contact with the guide frame.

[0009] Preferably, the outer wall of the limiting cylinder is provided with a threaded hole, and the inner wall of the threaded hole is threaded with a limiting bolt, and the connecting column is fixed inside the limiting cylinder by the limiting bolt.

[0010] Preferably, the top surface of the load-bearing base is rotatably provided with a placement column, the outer wall of the placement column is fitted with a limiting ring, the outer wall of the placement column is provided with a plurality of positioning holes, and the inner wall of the positioning holes is inserted with positioning pins.

[0011] Preferably, the load-bearing base has several placement slots on both the left and right sides, and counterweights are placed on the inner walls of the placement slots.

[0012] Compared with existing technologies, a continuous drawing machine for metal pressing products that adopts the above technical solution has the following beneficial effects:

[0013] 1. Through the coordinated action of the placement frame, bidirectional screw, clamping block, and connecting block, guide frames of different diameters can be clamped and fixed, allowing for flexible replacement of the guide frame according to the diameter of the metal wire. This effectively prevents wire wobbling within the guide frame caused by diameter mismatch, thereby improving the adaptability and reliability of the device. The threaded connection between the threaded ring and the bidirectional screw allows for limiting and fixing the bidirectional screw after rotation, preventing rotation due to equipment vibration during pulling, thus avoiding displacement of the clamping block and ensuring the stability of the guide frame clamping.

[0014] Second, the anti-slip pad increases the friction between the inner wall of the clamping block and the guide frame, effectively preventing slippage of the guide frame during feeding, thereby improving the reliability of the clamping block. The threaded hole and the limiting bolt work together to limit and fix the connecting column, allowing for flexible adjustment of the column's height. This prevents the placement frame from wobbling during drawing, ensures the straightness of the billet feeding, and indirectly improves the dimensional accuracy of the drawn product.

[0015] Third, the placement column allows for the placement of coiled metal wire, thereby limiting the axial position of coiled blanks of different thicknesses through the cooperation of the limiting ring and positioning pin, preventing the blanks from moving up and down during feeding. The synergistic effect of the placement groove and counterweight increases the overall weight of the load-bearing base, effectively reducing vibration during operation and preventing positioning deviations or component wear caused by vibration, thus improving the stability of the equipment during operation.

[0021] The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0022] like Figures 1-4 As shown, a metal pressing machine includes a load-bearing base 1, which is located on the left side of the machine body 2. A limiting cylinder 3 is connected to the inside of the load-bearing base 1 by screws. A connecting column 4 is inserted into the inner wall of the limiting cylinder 3. A placement frame 5 is rotatably mounted on the top of the connecting column 4. A receiving groove 6 is opened on the bottom surface of the inner side of the placement frame 5. A bidirectional screw 7 is rotatably mounted inside the placement frame 5 and extends into the receiving groove 6. Two clamping blocks 8 are slidably mounted on the inner wall of the placement frame 5. A connecting block 9 is fixed on the bottom surface of the clamping block 8 and slidably connected in the receiving groove 6. The connecting block 9 is threadedly connected to the outer wall of the bidirectional screw 7. A guide frame 10 is provided on the inner wall of the clamping block 8. An arc surface is opened on the inner wall of the guide frame 10. A threaded ring 11 is threadedly connected to the outer wall of the bidirectional screw 7.

[0023] In use, when metal wire needs to be pulled together, firstly, the metal wire coil can be placed on the outer wall of the placement column 15. Then, the limiting ring 16 is placed on the outer wall of the placement column 15 so that the bottom surface of the limiting ring 16 contacts the top of the metal wire. Subsequently, the positioning pin 18 is inserted into the corresponding positioning hole 17 to limit and fix the limiting ring 16 and the metal wire coil, preventing them from moving up and down during operation.

[0024] Secondly, a guide frame 10 matching the diameter of the metal wire can be placed between two clamping blocks 8. Then, rotate the bidirectional screw 7 clockwise to drive the two connecting blocks 9 and clamping blocks 8 closer to each other until the anti-slip pad 12 on the inner wall of the clamping block 8 is in close contact with the outer wall of the guide frame 10. Then, rotate the threaded ring 11 to make it tightly connected to the outer wall of the bidirectional screw 7 and in close contact with the outer wall of the placement frame 5. At the same time, the metal wire can be passed through the guide frame 10 and extended into the main body 2 of the connecting machine.

[0025] Finally, the height of the placement frame 5 can be adjusted so that the guide frame 10 and the feed end of the connecting machine body 2 are in the same axis. After the adjustment is completed, the limit bolt 14 can be tightened to limit and fix the connecting column 4, and then the connecting machine body 2 can be started to perform connecting drawing processing on the metal wire.

[0026] Through the coordinated action of the placement frame 5, the bidirectional screw 7, the clamping block 8, and the connecting block 9, guide frames 10 of different diameters can be clamped and fixed, allowing the guide frame 10 to be flexibly replaced according to the diameter of the metal wire. This effectively prevents the wire from shaking within the guide frame 10 due to diameter mismatch, thereby improving the adaptability and reliability of the device. The threaded connection between the threaded ring 11 and the bidirectional screw 7 limits and fixes the bidirectional screw 7 after rotation, preventing it from rotating due to equipment vibration during the pulling process. This also prevents the clamping block 8 from shifting, ensuring the stability of the guide frame 10.

[0027] like Figures 1-4 As shown, the inner wall of the clamping block 8 is fixed with an anti-slip pad 12, which is in contact with the guide frame 10. The outer wall of the limiting cylinder 3 is provided with a threaded hole 13, and the inner wall of the threaded hole 13 is threaded with a limiting bolt 14. The connecting column 4 is fixed in the limiting cylinder 3 by the limiting bolt 14. The top surface of the load-bearing base 1 is rotatably provided with a placement column 15. The outer wall of the placement column 15 is fitted with a limiting ring 16. The outer wall of the placement column 15 is provided with several positioning holes 17, and the inner wall of the positioning holes 17 is inserted with positioning pins 18. Several placement grooves 19 are provided on both the left and right sides of the load-bearing base 1, and counterweights 20 are placed on the inner wall of the placement grooves 19.

[0028] During use, the anti-slip pad 12 increases the friction between the inner wall of the clamping block 8 and the guide frame 10, effectively preventing slippage of the guide frame 10 during feeding, thereby improving the reliability of the clamping block 8. Through the synergistic action of the threaded hole 13 and the limiting bolt 14, the connecting column 4 can be limited and fixed, allowing for flexible adjustment of its height. This prevents the placement frame 5 from shaking during the drawing process, ensuring the straightness of the billet feeding and indirectly improving the dimensional accuracy of the drawn finished product.

[0029] The placement column 15 allows for the placement of coiled metal wire, thereby limiting the axial position of coiled blanks of different thicknesses through the cooperation of the limiting ring 16 and the positioning pin 18, preventing the blanks from moving up and down during feeding. The synergistic effect of the placement groove 19 and the counterweight 20 increases the overall weight of the load-bearing base 1, effectively reducing vibration during operation and preventing positioning deviations or component wear caused by vibration, thus improving the stability of the equipment during operation.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
