[0001] This utility model relates to the field of stretching technology for alloy wire production, specifically a stretching device for alloy wire production. Background Technology

[0002] Alloy wire drawing equipment is mainly used to draw metal wires into fine wires that meet standards through step-by-step drawing. Driven by technological development and application needs, it is constantly developing towards higher precision, higher efficiency, automation and intelligence.

[0003] Patent publication number CN210333794U relates to a copper alloy wire stretching device. This patent includes a base plate, with columns fixedly connected to both the upper left and right sides of the base plate. A winding roller is movably connected to the right end of the base plate via a support column. A fixing frame located to the left of the columns is fixedly connected to the top left end of the base plate. A groove is formed on the top left side of the base plate, and a slider is movably connected inside the groove. A movable rod is fixedly connected to the top of the slider, and a lower housing is fixedly connected to the top of the movable rod. A lower pressure roller is fixedly connected inside the lower housing. In this copper alloy wire stretching device, an electric push rod moves the upper housing downwards, causing the upper and lower pressure rollers to press and fix the copper alloy wire. A hydraulic cylinder moves the clamped copper wire a certain distance, and a motor drives a threaded rod to rotate, causing two clamping blocks to clamp and fix the other end of the copper alloy wire. Then, the hydraulic cylinder drives a transmission rod to move to the left, thereby achieving the purpose of stretching the copper alloy wire.

[0004] However, in existing technologies, after the machine finishes winding the wire, workers need to observe and manually stop the machine and cut the wire, which reduces the efficiency of stretching copper alloy wire. Furthermore, the inertia after the drive device stops will cause the winding wheel to continue rotating, affecting the efficiency of manually cutting the wire and disassembling the winding wheel.

The locking device includes a rotating rod 44, a column 6, a stop button 605, a first fixing plate 7, a fixing rod 701, a first spring 702, a Z-shaped rod 703, an L-shaped rod 704, and a cutting tool. 8. The following components are included: a third fixing plate 801, a second spring 802, a second fixing plate 803, a slot 901, and an L-shaped plate 705.

At the bottom, a first fixing plate 7 is fixedly installed at the bottom of a second fixing plate 801, a fixing rod 701 is fixedly installed at the front of the first fixing plate 7, a Z-shaped rod 703 is slidably installed on the surface of the first fixing plate 7, an L-shaped rod 704 is fixedly installed at the top of the Z-shaped rod 703, a first spring 702 is installed between the Z-shaped rod 703 and the fixing rod 701, a groove is provided on the side of the column 6 near the L-shaped rod 704, a slot 901 is provided at the output end of the drive device, a stop button 605 is fixedly installed inside the groove, and an L-shaped plate 705 is fixedly installed at the bottom of the first fixing plate 7. The rotating rod 4 rotates to drive the column 6 to move downward to release the restriction of the cutter 8 and realize automatic wire cutting. There is no need for manual observation of the winding situation, which improves the use effect and efficiency of copper alloy wire stretching. When the Z-shaped rod 703 moves to the left, it will contact the slot 901 to limit the drive device and prevent the winding wheel 9 from rotating under the action of inertia, which would cause the wire on the winding wheel 9 to loosen.

[0023] A compression rod 804 is fixedly installed between the third fixing plate 801 and the second fixing plate 803. The L-shaped rod 704 contacts the column 6. The stop button 605 is electrically connected to the drive device. The column 6 drives the groove to move downward, so that the L-shaped rod 704 is inserted into the groove and contacts the stop button 605, thereby stopping the drive device.

[0024] The box 1 is equipped with a wire clamping device, which includes a return spring 601, an elastic telescopic rod 602, a protrusion 603, a plug 604, and a square groove 607. The left side of the column 6 has an installation groove. The elastic telescopic rod 602 is slidably installed inside the installation groove. The return spring 601 is installed between the installation groove and the top of the elastic telescopic rod 602. The protrusion 603 is fixedly installed on the right side of the fixed end of the elastic telescopic rod 602. The plug 604 slides through the left side of the groove. The box 1 is rotatably equipped with a guide wheel 608. The surface of the guide wheel 608 has a square groove 607. The guide wheel 608 can clamp and restrict the end of the wire, preventing the end of the wire from moving randomly and causing the wire of the winding wheel 9 to loosen.

[0025] The housing 1 is equipped with a release device, which includes a support base 5, a connecting rod 501, a No. 3 spring 502, a semi-circular head slider 503, and a triangular head connecting rod 606. The support base 5 is fixedly installed inside the housing 1, the connecting rod 501 is fixedly installed at the bottom of the support base 5, the semi-circular head slider 503 slides through the interior of the connecting rod 501, the No. 3 spring 502 is located between the connecting rod 501 and the semi-circular head slider 503, and the triangular head connecting rod 606 is fixedly installed at the free end of the elastic telescopic rod 602, so that the semi-circular head slider 503 will drive the free end of the elastic telescopic rod 602 to move upward to release the limit on the guide wheel 608, so that the end of the line will not affect the disassembly of the winding wheel 9 when disassembling the winding wheel 9.

[0026] The semi-circular head slider 503 contacts the triangular head connecting rod 606. The semi-circular head slider 503 has a rounded corner on the side near the triangular head connecting rod 606. The triangular head connecting rod 606 moves upward by the movement of the semi-circular head slider 503 to the right. The rounded corner of the semi-circular head slider 503 reduces friction with the triangular head connecting rod 606.

[0027] The insert 604 is located behind the stop button 605. The insert 604 has a rounded corner on the side near the protrusion 603. A return spring 601 is provided between the column 6 and the elastic telescopic rod 602. When the insert 604 moves to the left and contacts the rounded corner of the protrusion 603, the leftward movement of the insert 604 will push the protrusion downward, causing the elastic telescopic rod 602 to move downward.

[0028] During operation: When the drive device drives the winding wheel 9, the winding wheel 9 will wind up the thread. The amount of thread wound on the winding wheel 9 will gradually increase. The increase in the amount of thread wound on the winding wheel 9 will push the rotating rod 4 to rotate clockwise. When the rotating rod 4 rotates clockwise, the right side of the rotating rod 4 will contact the column 6, so that the right side of the rotating rod 4 will push the column 6 downward. The downward movement of the column 6 will drive the groove to move downward. After the column 6 moves downward to a certain position, the groove moves to align with the L-shaped rod 704. Under the elastic force of the first spring 702, it will push the Z-shaped rod 703 and the L-shaped rod 704 to move. After the L-shaped rod 704 moves, it will contact the third fixed rod. When the fixed plate 801 disengages, the L-shaped rod 704 releases its obstruction of the third fixed plate 801, causing the spring force of the second spring 802 to push the third fixed plate 801 and the cutter 8 downwards. The downward movement of the cutter 8 will cut the wire on the L-shaped plate 705. At the same time, the L-shaped rod 704 moves and inserts into the groove. The insertion of the L-shaped rod 704 into the groove will press the stop button 605. The press of the stop button 605 will shut down the drive device and stop the winding wheel 9 from rotating. When the Z-shaped rod 703 moves, it will insert into the slot 901 to limit the drive device and prevent the inertia of the drive device from continuing to drive the winding wheel 9 to rotate.

[0029] When the L-shaped rod 704 is inserted into the groove, it will contact the insert block 604. The insertion of the L-shaped rod 704 into the groove will push the insert block 604 to the left. The leftward movement of the insert block 604 will contact the inclined surface of the protrusion 603. The leftward movement of the insert block 604 will push the protrusion 603 and the elastic telescopic rod 602 to slide downward. The downward sliding of the elastic telescopic rod 602 will cause the free section of the elastic telescopic rod 602 to insert into the square groove 607 of the guide wheel 608. The elastic telescopic rod 602 will limit the guide wheel 608, and the cut thread will be stuck between the guide wheels 608 to prevent the end of the thread from moving randomly and causing the thread of the winding wheel to loosen.

[0030] When the winding reel 9 finishes winding, disassembling the winding reel 9 will cause the winding reel 9 to contact the arc surface of the semi-circular head slider 503. The forward disassembly of the winding reel 9 will push the semi-circular head slider 503 to slide to the right. The semi-circular head slider 503 sliding to the right will contact the inclined surface of the triangular head connecting rod 606. The rightward sliding of the semi-circular head slider 503 will push the free section of the triangular head connecting rod 606 and the elastic telescopic rod 602 to move upward. The upward movement of the free section of the elastic telescopic rod 602 will release the restriction on the guide wheel 608, allowing the thread to be removed and thus completing the disassembly smoothly.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
