Description
Technical Field
[0001] The invention belongs to the technical field of tungsten wire winding, in particular to an auxiliary winding machine for tungsten wire production. Background Art
[0002] Tungsten wire is a thin wire made by forging and drawing tungsten bars. It is mainly used in electric light sources such as incandescent lamps and halogen tungsten lamps. With the improvement of people's living standards, tungsten wire is used more widely. The filament is the core component of electric vacuum devices. It needs to have a long service life and high temperature and high pressure resistance. The structure of the filament affects its performance, and the formation method directly affects the stability and quality of its structure.
[0003] After the production of some tungsten wires, they need to be wound on a reel for transportation and subsequent processing. However, the hardness of the tungsten wire is very high. When the tungsten wire is stretched from a tungsten block and wound on a reel, it is difficult to ensure that the tungsten wire fits the reel for bending. Generally, the tungsten wire is softened by heating to assist in winding the tungsten wire on the reel. The existing wire winding machines generally bend the tungsten wire through stress. This method easily causes uneven force on the tungsten wire, and the curled tungsten wire directly wound on the reel is prone to loosening. Summary of the invention

[0014] Preferably, a wedge-shaped sliding frame is slidably connected through the clamping block, a third return spring is provided between the wedge-shaped sliding frame and the fixed collar, and a baffle is fixedly connected to the lower side of the wedge-shaped sliding frame.
[0015] Preferably, the wedge-shaped sliding frame is wedge-matched with the clamping block, the wedge-shaped sliding frame is slidably connected to the fixing collar, and the wedge-shaped sliding frame is slidably connected to the connecting block.
[0016] Compared with the prior art, the present invention has the following beneficial effects:
[0017] The present invention cooperates with structures such as a winding motor and an external heating extrusion block, and the winding motor drives the winding wheel rim and the winding spool to rotate, so that the tungsten wire connected to the winding spool from the wire inlet sliding sleeve is curled and wound around the winding spool under the rotation of the winding spool. At the same time, the tungsten wire on the winding spool is heated and extruded by the external heating extrusion block, so that the tungsten wire is accelerated to bend. If the tungsten wire is harder, the external heating extrusion block slides up and down, cooperates with the rotation of the rotating extrusion plate, and then drives the connecting sliding shaft to slide up and down, so that the extrusion force of the external heating extrusion block on the tungsten wire is increased, ensuring that the tungsten wire is curled along the contour of the winding spool and is not easily deformed.
[0018] The present invention provides the coordination of structures such as the winding wheel rim and the inner heating block, and drives the rotating sleeve shaft to rotate synchronously in the rotating sleeve through the rotation of the winding wheel rim and the winding spool barrel, so that the transmission protrusion on the rotating sleeve shaft rotates synchronously, and then during the rotation of the transmission protrusion, the transmission extrusion shaft is squeezed by the transmission protrusion to deflect, and then the transmission extrusion shaft squeezes the limit stopper, so that the limit stopper also deflects, and then the inner heating block and the limit sliding block slide into the winding wheel rim and the winding spool barrel under the tension of the limit tension spring. When the transmission protrusion is separated from the transmission extrusion shaft, the transmission extrusion shaft and the limit stopper are no longer squeezed, and then the limit stopper again blocks the inner heating block and the limit sliding block from sliding into the winding wheel rim and the winding spool barrel under the tension of the limit tension spring, so that the tungsten wire is gradually heated as the tungsten wire is curled on the winding spool barrel. ;
[0019] The present invention cooperates with structures such as a fixed collar and a baffle plate, and the tungsten wire slides into the fixed collar, thereby squeezing the baffle plate to slide downward, thereby driving the wedge-shaped sliding frame to slide downward synchronously. Through the wedge-shaped cooperation between the wedge-shaped sliding frame and the clamping block, the wedge-shaped sliding frame squeezes the clamping block to slide along the connecting block toward the tungsten wire, thereby causing the clamping block to squeeze and clamp the tungsten wire, thereby ensuring that the end of the tungsten wire is always fixed during the process of winding the tungsten wire on the winding spool, thereby preventing the tungsten wire from spreading during the winding process.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0033] like Figures 1 to 11As shown, the present invention provides a tungsten wire production auxiliary winding machine, including a mounting platform 100, wherein a wire inlet sliding sleeve 101 is fixedly connected to the mounting platform 100, a symmetrically distributed rotating sleeve 203 is fixedly connected to the mounting platform 100, a motor mounting frame 201 is fixedly connected to the mounting platform 100, a winding motor 200 is installed in the motor mounting frame 201, a transmission spline shaft 202 is fixedly connected to the output shaft of the winding motor 200, a rotating sleeve shaft 204 is rotatably connected in the rotating sleeve 203, a winding wheel rim 300 is spline-connected between the transmission spline shaft 202 and the rotating sleeve shaft 204, a winding wheel rim 300 is fixedly connected to a winding shaft barrel 301, and an internal heating block 600 is slidably connected in the rotating sleeve shaft 204;
[0034] Among them, the rotating sleeve 203 close to the guide sliding shaft 607 is fixedly connected with a limiting sliding frame 604, the guide sliding shaft 607 is fixedly connected to the internal heating block 600, the guide sliding shaft 607 is fixedly connected with an array-distributed limiting sliding block 602, the limiting sliding frame 604 is rotatably connected with a limiting stopper 606, the rotating sleeve 203 is rotatably connected with a transmission extrusion shaft 605, the rotating sleeve shaft 204 is fixedly connected with a transmission protrusion 603, the transmission protrusion 603 is extruded and matched with the transmission extrusion shaft 605, and the transmission extrusion shaft 605 is extruded and matched with the limiting stopper 606.
[0035] The inner heating block 600 is slidably connected with the winding wheel rim 300 and the winding spool 301 , and the winding spool 301 is provided with a circumferential array of through grooves.
[0036] A limit tension spring 601 is wound around the guide sliding shaft 607 , and the limit tension spring 601 is connected to the limit sliding frame 604 .
[0037] A torsion spring is provided between the limit stopper 606 and the limit sliding frame 604 . The limit stopper 606 is extruded and matched with the limit sliding block 602 . The size of the limit stopper 606 is smaller than the gap size between adjacent limit sliding blocks 602 .
[0038] The rotating sleeve 203 is fixedly connected with a rotating shaft mounting frame 400, the rotating shaft mounting frame 400 is fixedly connected with a winding shaft 401, the winding shaft 401 is spline-connected with a winding sliding frame 402, and a first return spring 403 is arranged between the winding sliding frame 402 and the rotating shaft mounting frame 400.
[0039] The winding sliding frame 402 is fixedly connected with symmetrically distributed rotating connecting plates 405 , and the rotating connecting plates 405 are rotatably connected with rotating extrusion plates 406 , and the lower side of the rotating extrusion plates 406 is rotatably connected with symmetrically distributed connecting sliding shafts 407 .
[0040] The connecting sliding shaft 407 is slidably connected to the external heating extrusion block 404 . A second return spring 408 is wound around the connecting sliding shaft 407 . The second return spring 408 is connected to the upper side of the external heating extrusion block 404 .
[0041] The above scheme is adopted: during the process of winding the tungsten wire on the winding spool 301, the winding motor 200 drives the winding wheel rim 300 and the winding spool 301 to rotate, thereby driving the rotating sleeve 204 and the transmission protrusion 603 to rotate. When the rotating sleeve 204 and the transmission protrusion 603 rotate one circle, the transmission protrusion 603 squeezes the transmission extrusion shaft 605, and then the transmission extrusion shaft 605 squeezes the limit stopper 606, so that the limit stopper 606 is separated from the limit sliding block 602, and then the internal heating block 600 and the limit sliding block 602 are pulled by the limit tension spring 601. The tungsten wire curled on the winding reel 301 is heated from the inside by the internal heating block 600, and the tungsten wire is curled by the heat. The internal heating block 600 slides partially inward by rotating the sleeve 204 for one circle. At the same time, when the tungsten wire is curled on the winding reel 301, it is heated and squeezed by the external heating and squeezing block 404. If the tungsten wire is squeezed and the external heating and squeezing block 404 close to the line inlet sleeve 101 slides upward, the other external heating and squeezing block 404 slides downward to squeeze the tungsten wire, thereby ensuring that the tungsten wire is curled on the winding reel 301.
[0042] like Figure 7 , Figure 8 and Fig.11 As shown, a fixing ring 500 is fixedly connected to the winding spool drum 301 , and a connecting block 504 distributed in a circumferential array is fixedly connected to the bottom of the fixing ring 500 , and a clamping block 505 is slidably connected through the connecting block 504 .
[0043] A wedge-shaped sliding frame 502 is slidably connected through the clamping block 505 , a third return spring 501 is provided between the wedge-shaped sliding frame 502 and the fixed collar 500 , and a baffle 503 is fixedly connected to the lower side of the wedge-shaped sliding frame 502 .
[0044] The wedge-shaped sliding frame 502 is wedge-matched with the clamping block 505 , the wedge-shaped sliding frame 502 is slidably connected with the fixing ring 500 , and the wedge-shaped sliding frame 502 is slidably connected with the connecting block 504 .
[0045] The above solution is adopted: the tungsten wire slides into the fixed ring 500 so that the tungsten wire is clamped and squeezed by the clamping block 505, ensuring that the end of the tungsten wire will not get loose during the process of curling on the winding spool tube 301, and at the same time ensuring that the tungsten wire is curled on the winding spool tube 301 under force.
[0046] The working principle and use process of the present invention:
[0047] First, the operator passes the tungsten wire through the pores on the wire inlet sleeve 101 to connect it to the winding spool 301, and then starts the winding motor 200, which drives the motor mounting frame 201 to rotate, and then drives the winding wheel rim 300 to rotate synchronously, and then drives the winding spool 301 to rotate synchronously, so that the tungsten wire connected to the winding spool 301 is curled around the winding spool 301. In the process of the tungsten wire curling on the winding spool 301, as the winding wheel rim 300 and the winding spool 301 rotate, the rotating sleeve 204 is driven to rotate in the rotating sleeve 203, and the transmission protrusion 603 on the rotating sleeve 204 is driven to rotate synchronously through the rotating sleeve 204. When the transmission protrusion 603 rotates one circle, the transmission protrusion 603 squeezes the transmission extrusion shaft 605, so that the transmission extrusion shaft 606 05 deflects accordingly, and then the transmission extrusion shaft 605 squeezes the limit block 606, causing the limit block 606 to deflect accordingly, thereby causing the internal heating block 600 and the limit sliding block 602 to slide into the winding wheel rim 300 and the winding spool tube 301 under the tension of the limit tension spring 601. After the internal heating block 600 and the limit sliding block 602 slide for a certain distance, the transmission protrusion 603 separates from the transmission extrusion shaft 605, and then the transmission extrusion shaft 605 no longer squeezes the limit block 606. The limit block 606 is reset through the torsion spring between the limit block 606 and the limit sliding frame 604, and then the limit block 606 is squeezed by the limit sliding block 602 again, preventing the internal heating block 600 and the limit sliding block 602 from continuing to slide into the winding wheel rim 300 and the winding spool tube 301.
[0048] At the same time, as the winding wheel rim 300 and the winding spool 301 rotate, the tungsten wire is wound around the winding spool 301, and the tungsten wire that is wound from the wire inlet sleeve 101 to the winding spool 301 is heated and squeezed by the external heating and squeezing block 404. As the tungsten wire is wound on the winding spool 301, the external heating and squeezing block 404 always heats and squeezes the tungsten wire that is wound from the wire inlet sleeve 101 to the winding spool 301, thereby driving the external heating and squeezing block 404 and the winding sliding frame 402 to slide along the winding shaft 401. When the tungsten wire is wound on the winding spool 301, If the tungsten wire is harder, the external heating extrusion block 404 close to the wire feed sleeve 101 is squeezed to slide upward, thereby causing the external heating extrusion block 404 to slide upward along the connecting sliding shaft 407, thereby squeezing the second return spring 408, and at the same time causing the rotating extrusion plate 406 to rotate around the rotating connecting plate 405, thereby causing the other connecting sliding shaft 407 to slide downward, and then the external heating extrusion block 404 is squeezed downward by the second return spring 408, so that the tungsten wire is squeezed and enhanced by the other external heating extrusion block 404, ensuring that the tungsten wire is bent and fits the winding spool tube 301.
[0049] When the tungsten wire is connected to the winding spool 301 from the wire inlet sleeve 101, the operator puts the tungsten wire into the fixed ring 500, and then as the tungsten wire slides in the fixed ring 500, the extrusion baffle 503 slides downward, thereby driving the wedge-shaped sliding frame 502 to slide downward synchronously, and the third reset spring 501 is stretched, and the wedge-shaped sliding frame 502 cooperates with the clamping block 505, so that the clamping block 505 slides toward the tungsten wire along the connecting block 504, thereby squeezing and clamping the tungsten wire, and then the winding motor 200 drives the winding wheel rim 300 and the winding spool 301 to rotate, so that the tungsten wire is curled and wound on the winding spool 301.
