Description

Technical Field

[0001] This utility model relates to the field of metal processing technology, and in particular to a wire drawing and unwinding device for metal products. Background Technology

[0002] In existing technology, wire drawing machines are pre-processing equipment for the production of standard parts and other metal products. A metal wire drawing machine mainly includes a wire feeding device, a stretching mechanism, a wire take-up device, and a control system. The wire feeding device is responsible for smoothly and continuously feeding the metal wire to be processed into the wire drawing machine. The design of the wire feeding device needs to consider the tension control of the metal wire to avoid wire breakage due to excessive tension or slack due to insufficient tension.

[0003] A search revealed Chinese patent application number 202321558432.5, which discloses a wire drawing and unwinding device for metal product processing. The device includes a frame, a wire unwinding rod horizontally fixed to the frame, a wire unwinding wheel sleeved on the wire unwinding rod, and a clamping assembly that constantly presses against the metal wire on the wire unwinding wheel. The frame has two guide wheels, one vertically spaced and positioned vertically in front of the wire unwinding rod, with a gap between them for the metal wire to pass through. The clamping assembly presses the metal wire on the wire unwinding wheel, preventing the wire from unwinding during processing. During unwinding, the metal wire is positioned between the guide wheels, which provide guidance. These guide wheels, in conjunction with the clamping assembly, ensure orderly unwinding of the metal wire, improving the efficiency of metal product processing.

[0004] The above-mentioned patent has the following shortcomings: In actual use, the device presses the metal wire roll with the wire pressing component to ensure the unwinding speed of the metal wire roll; the wire drawing machine continuously feeds the metal wire through the traction structure, and there are tension changes in the metal wire between the traction mechanism and the unwinding device. If the tension is too large or too small, it will affect the processing of the metal wire. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] A wire drawing and unwinding device for metal products, such as Figures 1 to 5As shown, the top support frame 2 includes a metal wire guide assembly, a tension adjustment assembly, and a tension testing assembly installed sequentially at the bottom. The bottom of the top support frame 2 is fixedly mounted with a bearing base 1 through multiple connecting columns (not shown). The metal wire guide assembly, tension adjustment assembly, and tension testing assembly are positioned above the bearing base 1.

[0026] A main control box 3 is fixedly installed on one side of the top of the support base 1. A three-jaw chuck 4 is installed on the front of the main control box 3. A wire reel 5 is clamped on the front of the three-jaw chuck 4. The main control box 3 is equipped with a drive motor and a reducer to control the rotation of the three-jaw chuck 4. The three-jaw chuck 4 can clamp various types of wire reels 5.

[0027] The metal wire reel 5 contains a coarse metal wire 6 to be processed. The coarse metal wire 6 passes sequentially through the coarse metal wire guide assembly, the tension adjustment assembly, and the tension testing assembly. The coarse metal wire guide assembly is used to stabilize the out-of-winding direction of the coarse metal wire 6, ensuring that the coarse metal wire 6 enters the tension adjustment assembly stably. The tension adjustment assembly is used to adjust the tension of the coarse metal wire 6 before it enters the drawing device, ensuring that the tension of the coarse metal wire 6 is stable within a suitable range to guarantee the processing effect of the coarse metal wire 6. The tension testing assembly is used to test the tension of the coarse metal wire 6 and stably guide the coarse metal wire 6 into the drawing device.

[0028] The main control box 3 is also equipped with a controller. The controller receives the tension data of the metal wire 6 to be processed from the tension testing component, and then controls the tension adjustment component to adjust the tension of the metal wire 6 to be processed.

[0029] The metal wire guide assembly includes a horizontal roller pair 9 and a vertical roller pair 10 that are perpendicular to each other and fixedly connected. A connecting rod 8 is fixedly installed on the top of the horizontal roller pair 9. Connecting ear plates are fixedly connected to both sides of the vertical roller pair 10. Connecting rods 8 are fixedly connected to the upper surface of the connecting ear plates. A fixed mounting bracket 7 is fixedly connected to the top of the multiple connecting rods 8. The fixed mounting bracket 7 is fixedly installed at the bottom of the top support frame 2.

[0030] The main body of both the horizontal roller frame 9 and the vertical roller frame 10 is configured with two side wall plates. Two clamping rollers are rotatably installed between the two side wall plates. The outer walls of the two clamping rollers are in contact, and a slot for limiting the metal wire is opened in the middle of the outer wall of the clamping roller.

[0031] like Figure 2 As shown, the horizontal roller set 9 is close to the wire reel 5, which facilitates the feeding of the coarse metal wire 6 to be processed, which is wound inside the wire reel 5, into the vertical roller set 10.

[0032] The tension adjustment assembly includes a tension adjustment cylinder 12 and a tension adjustment roller bracket 13. The tension adjustment roller bracket 13 is fixedly installed at the bottom of the telescopic end of the tension adjustment cylinder 12. A cylinder mounting bracket 11 is fixedly installed on the outer wall of the tension adjustment cylinder 12. The cylinder mounting bracket 11 is fixedly installed at the bottom end of the top support bracket 2. The main control box 3 controls the extension length of the tension adjustment cylinder 12. Figure 2 and Figure 4 As shown, at this time, the tension adjusting cylinder 12 is in a non-extension state, and the unwound metal wire 6 is in a horizontal state.

[0033] The tension testing assembly includes a connecting slide bar 16 and a tension testing roller pair 17. The tension testing roller pair 17 is fixedly installed at the bottom end of the connecting slide bar 16. A U-shaped mounting bracket 15 is slidably sleeved on the outer wall of the connecting slide bar 16 through a linear bearing. A mounting plate 14 is fixedly connected to the top end of the U-shaped mounting bracket 15. The mounting plate 14 is fixedly installed at the bottom end of the top support frame 2.

[0034] like Figure 5 As shown, the top end of the connecting slide rod 16 passes through the U-shaped mounting bracket 15 and extends upward. Its extended end is located inside the groove of the U-shaped mounting bracket 15, and a test connecting arm 18 is fixedly installed on the top of the extended end of the connecting slide rod 16.

[0035] Test springs 19 are fixedly installed at the bottom of both ends of the test connecting arm 18. Test pressure plates 20 are fixedly connected to the bottom of the test springs 19. Pressure detection sensors 21 are set at the bottom of the test pressure plates 20. The pressure detection sensors 21 are fixedly installed on the inner wall of the groove at the bottom of the U-shaped mounting bracket 15. The sum of the measurement data of the two pressure detection sensors 21 is twice the current tension force on the metal wire 6 to be processed.

[0036] Both ends of the lower surface of the mounting plate 14 are fixedly installed with connecting mounting rods 22, and the bottom end of the connecting mounting rods 22 is fixedly installed with guide rollers 23.

[0037] The guide roller pair 23, tension test roller pair 17 and tension adjustment roller pair 13 have the same structure. Their main body is set as a mating connection frame. The bottom end of the mating connection frame is provided with an installation groove. Two clamping mating rollers with mutually touching surfaces and arranged at different positions are rotatably installed inside the installation groove. A metal wire slot is provided in the middle of the outer wall of the clamping mating roller.

[0038] Initial state of the tension test assembly: The tension test roller pair 17 hangs down naturally and drives the test connecting arm 18 to compress the test spring 19 through the connecting slide rod 16. The test spring 19 applies pressure to the pressure detection sensor 21 through the test pressure plate 20, and then the test value of the pressure detection sensor 21 is zeroed. At this time, the tension test roller pair 17 is higher than the guide roller pair 23.

[0039] Working principle:

[0040] Please refer to Figures 1 to 5 Assemble the device as shown in the figure;

[0041] In use, the wire reel 5, with the metal wire 6 to be processed wound around it, is first fixed on the three-jaw chuck 4. Then, the metal wire 6 is passed sequentially through the horizontal roller frame 9, the vertical roller frame 10, the tension adjusting roller frame 13, the guide roller frame 23, the tension testing roller frame 17, and finally into the wire drawing device. The wire drawing device is then activated to draw the metal wire 6. Simultaneously, the three-jaw chuck 4 is rotated via the main control box 3 to unwind the metal wire 6. The tension adjusting cylinder 12 is also extended to lower the tension adjusting roller frame 13. The movement of the metal wire 6 to be processed puts it under stress and gradually tightens it so that the tension force on the metal wire 6 meets the processing requirements. As the metal wire 6 is gradually tightened, the tension test roller frame 17 moves downward, which in turn causes the test connecting arm 18 to compress the test spring 19. The sum of the test data after the pressure detection sensor 21 is zeroed is twice the sum of the test data, which is within the tension force range required for the processing of the metal wire 6. During the unwinding process of the metal wire 6, if the sum of the test data is too large, the tension adjustment cylinder 12 is contracted; conversely, if the sum of the test data is too large or too small, the tension adjustment cylinder 12 is extended.

[0042] 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.
