Description

Technical Field

[0001] The utility model relates to the technical field of large drawing annealing, in particular to a double-head large drawing AC annealing device. Background Art

[0002] A large drawing machine is a device specifically used for the stretching and annealing treatment of copper wires, aluminum wires, brass wires, and copper-magnesium alloy wires for high-speed rail contact wires. Its core function is to apply a specific constant-temperature heating process to the stretched metal wire rods, and then through the way of cooling and quenching to improve the mechanical strength of these metal wires. In practical applications, large drawing machines are divided into two types: single-head large drawing machines and double-head large drawing machines according to different functions and structures.

[0003] During the annealing process of alloy wires, the alloy wires usually need to pass through the double-head large drawing machine horizontally for continuous drawing and annealing operations. However, due to the lack of a special limiting device to fix the alloy wires in a specific position, during the drawing and annealing processes, the alloy wires are prone to deformation and displacement, thus unable to maintain their dimensional accuracy and consistency. At the same time, the displaced alloy wires may even break due to excessive deformation or uneven forces during the drawing process, resulting in the idling of the equipment and affecting its service life. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the problems existing in the prior art, and a double-head large drawing AC annealing device is proposed.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] Double-headed large drawing AC annealing device, including a large drawing machine body with annealing function and alloy wires horizontally penetrating the large drawing machine body. A hinged door is movably connected to the front of the large drawing machine body through a hinge. Installation openings for facilitating the passage of the alloy wires are provided on both vertical outer walls of the large drawing machine body. Three pairs of vertical plates are slidably arranged vertically on the large drawing machine body. A first limiting structure for limiting the alloy wire in the vertical direction is arranged on the large drawing machine body. A protection device for preventing the alloy wire from being broken is arranged on the large drawing machine body. A second limiting structure for limiting the alloy wire in the horizontal direction is arranged in the installation opening. The first limiting structure includes a lifting cylinder fixedly connected to the top of the large drawing machine body. The output end at the top of the lifting cylinder is fixedly connected to a transmission plate, and the transmission plate is fixed to the vertical plates on both sides. The bottom ends of the three pairs of vertical plates extend into the large drawing machine body and are rotatably connected to limiting rollers. A pair of bottom plates are fixedly connected to the inner wall of the bottom of the large drawing machine body. A loading roller is rotatably connected to the bottom plate. The loading roller corresponds to the limiting rollers on both sides. The second limiting structure includes a bidirectional lead screw rotatably connected in the installation opening. A pair of moving plates are threadedly connected to the bidirectional lead screw, and the moving plates are horizontally slidably connected to the installation opening. A motor for driving the bidirectional lead screw to rotate is fixedly connected to the large drawing machine body. A sliding opening for facilitating the vertical sliding of the vertical plate is provided at the top of the large drawing machine body.

[0007] To better achieve the above object, the present utility model adopts a further technical solution: The protection device includes a cross plate fixedly connected to the middle vertical plate. A sliding rod is fixedly connected to the top of the large drawing machine body. The sliding rod is vertically slidably connected to the cross plate. A warning light is fixedly installed at the top of the sliding rod. A spring is sleeved on the sliding rod, and both ends of the spring are fixedly connected to the large drawing machine body and the cross plate respectively. A pressing block is fixedly connected to the bottom of the cross plate. A switch button corresponding to the pressing block is fixedly installed at the top of the large drawing machine body.

[0008] To better achieve the above object, the present utility model adopts a further technical solution: A support member for fixedly supporting the cross plate is arranged at the top of the large drawing machine body. The support member includes a sleeve fixedly connected to the top of the large drawing machine body. An inner rod is vertically slidably connected to the sleeve, and the top of the inner rod is fixedly connected to the bottom of the cross plate. A top screw for limiting the inner rod is threadedly connected to the sleeve.

[0009] The advantages of the present utility model are as follows: Through the arrangement of the first limiting structure and the second limiting structure, the transmission plate driven by the lifting cylinder to move vertically is fixed on the two side vertical plates. The limiting roller corresponds to the load-carrying roller rotatably connected to the bottom plate. A pair of moving plates are threadedly connected to the bidirectional lead screw driven by the motor to rotate. Through the arrangement of the limiting roller, the load-carrying roller and the moving plates, all-round limiting of the alloy wire is achieved, ensuring that the alloy wire can maintain the correct position during the annealing process, thereby avoiding potential damage caused by displacement and improving production efficiency and product quality. Through the arrangement of the protection structure, the cross plate fixedly connected to the vertical plate at the middle position is slidably connected to the sliding rod. The two ends of the spring sleeved on the sliding rod are respectively fixedly connected to the large drawing machine body and the cross plate. The pressing block corresponding to the switch button is fixed at the bottom of the cross plate. When the alloy wire breaks during the annealing process, the tension originally exerted by the alloy wire suddenly disappears, and the pressing block moves down to accurately press the switch button, activating the warning light, ensuring that the operator can obtain the alarm in the first time and thus take measures to stop the operation of the equipment, effectively avoiding the idling of the equipment and potential damage caused by the breakage of the alloy wire.

[0015] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model.

[0016] Refer to Figures 1 - 4As shown in the figure, the double-head large drawing AC annealing device includes a large drawing machine body 1 with annealing function and an alloy wire 2 horizontally penetrating the large drawing machine body 1. A switch door 3 is movably connected to the front of the large drawing machine body 1 through a hinge. Installation openings 4 for facilitating the passage of the alloy wire 2 are provided on both vertical outer walls of the large drawing machine body 1. Three pairs of vertical plates 7 slide vertically on the large drawing machine body 1; the setting of the switch door 3 facilitates the operator to perform equipment maintenance and daily inspections. A first limiting structure for limiting the alloy wire 2 in the vertical direction is provided on the large drawing machine body 1. A protection device for preventing the alloy wire 2 from being broken is provided on the large drawing machine body 1. A second limiting structure for limiting the alloy wire 2 in the horizontal direction is provided in the installation opening 4. The first limiting structure includes a lifting cylinder 5 fixedly connected to the top of the large drawing machine body 1. The output end at the top of the lifting cylinder 5 is fixedly connected to a transmission plate 6, and the transmission plate 6 is fixed to the vertical plates 7 on both sides. The bottom ends of the three pairs of vertical plates 7 all extend into the large drawing machine body 1 and are rotatably connected to limiting rollers 8. A pair of bottom plates 9 are fixedly connected to the inner wall of the bottom of the large drawing machine body 1. A load-carrying roller 10 is rotatably connected to the bottom plate 9. The load-carrying roller 10 and the limiting rollers 8 provided on both sides are correspondingly arranged. The load-carrying roller 10 and the limiting rollers 8 are in contact with the alloy wire 2 to limit the alloy wire 2 without hindering its movement; the second limiting structure includes a bidirectional lead screw 20 rotatably connected in the installation opening 4. A pair of moving plates 21 are threadedly connected to the bidirectional lead screw 20, and the moving plates 21 are horizontally slidably connected to the installation opening 4. A motor 22 for driving the bidirectional lead screw 20 to rotate is fixedly connected to the large drawing machine body 1. The purpose of the horizontal sliding connection between the moving plate 21 and the installation opening 4 is to ensure that the moving plate 21 can stably move along the axis direction of the bidirectional lead screw 20. A sliding opening 23 for facilitating the vertical sliding of the vertical plate 7 is opened at the top of the large drawing machine body 1.

[0017] The protective device includes a cross plate 11 fixedly connected to the middle vertical plate 7. A sliding rod 13 is fixedly connected to the top of the large drawing machine body 1. The sliding rod 13 is vertically slidably connected to the cross plate 11. A warning light 12 is fixedly installed at the top of the sliding rod 13. A spring 14 is sleeved on the sliding rod 13, and both ends of the spring 14 are fixedly connected to the large drawing machine body 1 and the cross plate 11 respectively. A pressing block 15 is fixedly connected to the bottom of the cross plate 11. A switch button 16 corresponding to the pressing block 15 is fixedly installed at the top of the large drawing machine body 1. The warning light 12 can remind the operator to turn off the device after the alloy wire 2 is broken, preventing the device from idling or even being damaged. When the alloy wire 2 is broken, under the action of the spring 14, the pressing block 15 moves vertically downward to press the switch button 16 to turn on the warning light 12 for alarm. A support member for fixedly supporting the cross plate 11 is provided at the top of the large drawing machine body 1. The support member includes a sleeve 17 fixedly connected to the top of the large drawing machine body 1. An inner rod 18 is vertically slidably connected to the sleeve 17, and the top of the inner rod 18 is fixedly connected to the bottom of the cross plate 11. A top screw 19 for limiting the inner rod 18 is threadedly connected to the sleeve 17. When the device is idle, after fixing the inner rod 18 by screwing the top screw 19, the pressing block 15 can be far away from the switch button 16, thereby preventing the warning light 12 from continuously alarming due to the pressing block 15 continuously pressing the switch button 16 during idleness, resulting in noise pollution.

[0018] Preparation stage of the present utility model: Ensure that the large drawing machine body 1 is in the closed state, and the opening and closing door 3 is opened for equipment inspection and maintenance. Check whether the alloy wire 2 has been correctly installed in the large drawing machine body 1, and ensure that the alloy wire 2 is correctly placed through the installation opening 4. Starting stage: Close the opening and closing door 3 and start the large drawing machine body 1 to make the equipment start running.

[0019] Activate the motor 22 to drive the bidirectional lead screw 20 to rotate, so that the moving plate 21 slides horizontally along the installation opening 4 to limit the alloy wire 2 in the horizontal direction. Operate the lifting cylinder 5 to drive the limiting roller 8 to move up and down through the transmission plate 6 and the vertical plate 7, and adjust to a height suitable for drawing the alloy wire 2. Drawing and annealing process: The alloy wire 2 is drawn and annealed in the large drawing machine body 1. The carrier roller 10 and the limiting roller 8 cooperate to ensure that the alloy wire 2 remains stable during the drawing process and avoid deviation or damage. If the alloy wire 2 is broken, the originally compressed spring 14 pushes the pressing block 15 downward under the action of its elastic force, triggering the switch button 16 to turn on the warning light 12 to remind the operator to stop the machine for inspection. End stage: After the drawing and annealing are completed, turn off the large drawing machine body 1 and stop the motor 22.

[0020] Open the opening and closing door 3, release the pressure of the lifting cylinder 5, restore the first limit structure to its initial position, and take out the processed alloy wire 2; Turn the setscrew 19 to adjust the support member, and the setscrew 19 abuts against the inner rod 18, so that the pressing block 15 is far away from the switch button 16 to prevent false alarms during idle time.
