For example, the extrusion equipment is connected to the external precision single-screw extruder, and the traction equipment is connected to the winding system. No further details are given here. Then, before the wire drawing production is carried out, the working state of the traction equipment can be changed by manually driving the linkage control frame 2. For example, the corresponding traction wheel structure can be adjusted according to the diameter of the production consumable wire 6 to connect with the consumable wire 6 produced subsequently. During the movement of the linkage control frame 2, on the one hand, the structure of the cooling control water tank section 4 can be changed to achieve a better cooling effect (for example, when the diameter of the consumable wire 6 is large, the cooling effect needs to be increased.

[0035] The traction adjustment assembly comprises: Rotating rods 23, the number of the rotating rods 23 is two, and the two rotating rods 23 are both rotatably connected to the linkage control frame 2 and connected to the traction drive device 5; Wherein, each of the rotating rods 23 is provided with a plurality of adjustable traction wheels 24, and each two of the adjustable traction wheels 24 form a pair, and the consumable wire 6 is located between one pair of the adjustable traction wheels 24, and the diameters of the multiple pairs of the adjustable traction wheels 24 are different; And a pressure control member 22 , wherein the pressure control member 22 is fixedly mounted on the linkage control frame 2 and connected to the rotating rod 23 , and the pressure control member 22 is used to control the diameter size of the plurality of adjustable traction wheels 24 on the rotating rod 23 .

[0036] The extrusion equipment comprises: A connecting seat 13, wherein the connecting seat 13 is fixedly connected to the wire drawing support frame 1, and the connecting seat 13 is also connected to an external single-screw extruder; And an extrusion tube 10 , wherein the extrusion tube 10 is detachably mounted on the connection seat 13 and connected to the cooling control component, and a wire extrusion port 38 is also provided on the extrusion tube 10 .

Under the extrusion action of the external single-screw extruder, the molten material will enter the extrusion tube 10 and finally be extruded through the wire extrusion port 38. At the same time, according to the diameter of the consumable wire 6 to be produced, the linkage control frame 2 can be manually operated to drive the rotating rod 23 to move and change the positions of the multiple adjustable traction wheels 24. Since the diameters of the multiple pairs of adjustable traction wheels 24 are different, the consumable wires 6 of different diameters can be pulled.

[0040] The cooling control assembly comprises: A support baffle 9, wherein the support baffle 9 is fixedly mounted on the wire drawing support frame 1, and a sealing support 19 is also fixedly mounted on the support baffle 9, wherein the sealing support 19 is slidably connected to the cooling control water tank section 4 and is fixedly connected to the sealing slot plate 18; A water inlet pipe 20, one end of which passes through the sealing support 19 and is fixedly mounted with a nozzle portion 21, and the nozzle portion 21 is arranged facing the extrusion device; A flow control cylinder 16, wherein the flow control cylinder 16 is fixedly connected to the other end of the water inlet pipe 20 and is connected to the return water pipe 15, and a flow regulating member 34 is also provided on the flow control cylinder 16; And a control tooth plate 33 , the control tooth plate 33 is slidably connected to the wire drawing support frame 1 through a sliding support 17 , and is connected to the flow regulating member 34 , and the control tooth plate 33 is also connected to the linkage control frame 2 .

[0041] It also includes: a smooth square frame 35, the smooth square frame 35 is fixedly connected to the control tooth plate 33; A telescopic member 37, wherein the telescopic member 37 is fixedly mounted on the wire drawing support frame 1, and the telescopic member 37 is also electrically connected to the traction device; And a driving inclined block 36 , one end of which is fixedly connected to the output end of the telescopic member 37 , and the other end of which is inserted into the smooth square frame 35 and slidably connected to the smooth square frame 35 .

[0042] When the annular airbag is deformed, the sensor will control the refrigeration device 12 to start, wherein the refrigeration device 12 can also be in the form of an air pump, so that air can be blown to the clean water in the cooling control water tank section 4 through the air holes on the multifunctional support plate 11 for cooling (one end of the multifunctional support plate 11 can extend into the cooling water), and the turbulence effect on the clean water can be improved, so that the cooling water at different parts can contact with the consumable wire 6, thereby improving the cooling effect on the consumable wire 6. Of course, the refrigeration device 12 can also be in the form of a coolant tank, and under the control of the sensor, coolant is directly added to the clean water in the cooling control water tank section 4, which will not be described in detail here; The clean water discharged from the end of the cooling control water tank section 4 will flow into the water tank 7, and will flow back to the flow control cylinder 16 again through the water pumping equipment 14 and the return water pipe 15, wherein a circular plate-shaped valve core is arranged in the flow control cylinder 16, and the position state of the valve core is controlled by the flow regulating member 34, and the flow regulating member 34 can be in the form of a gear and a rotating rod, the gear is meshed and connected with the control tooth plate 33, the rotating rod passes through the flow control cylinder 16, and is connected with the valve core, then during the movement of the linkage control frame 2, the control tooth plate 33 will be driven to move synchronously, thereby driving the flow regulating member 34 to rotate. The flow control cylinder 16 is moved to change the position state of the valve core in the flow control cylinder 16 (when the circular plate-shaped valve core is in a horizontal state, the flow control cylinder 16 will be completely blocked, and when the circular plate-shaped valve core is in a vertical state, the flow control cylinder 16 is in a fully open state), so as to achieve the purpose of adjusting the flow of cooling water, and the cooling water will flow into the water inlet pipe 20 after passing through the flow control cylinder 16, and finally be sprayed into the cooling control water tank section 4 through the nozzle part 21, wherein the nozzle part 21 is an arc-shaped structure, and is directly opposite to the wire extrusion outlet 38, so that the consumable wire 6 can be fully cooled, which will not be described in detail here; When the position of the linkage control frame 2 remains unchanged and the annular airbag is deformed, the traction speed may need to be increased. At this time, it is also necessary to improve the cooling effect of the cooling control water tank section 4 on the consumable wire 6. Under the control of the sensor in the annular airbag, the telescopic member 37 is started, wherein the telescopic member 37 can be in the form of a cylinder or a telescopic cylinder, thereby pushing the driving inclined block 36 to move downward and pushing the smooth square frame 35 to move to the left (as shown in the multifunctional support plate 11 in the figure), thereby achieving the purpose of regulating the cooling water flow. At the same time, in order to avoid the smooth square frame 35 driving the control tooth plate 33 to move during the movement, the linkage control frame 2 will drive When the adjustable traction wheel 24 moves, the linkage control frame 2 and the control tooth plate 33 can be connected in a sliding manner. Under normal working conditions, the linkage control frame 2 and the control tooth plate 33 can be connected by an electromagnet or a limiting structure is set at a certain position (the linkage control frame 2 and the limiting structure are in contact with each other), so that the linkage control frame 2 drives the control tooth plate 33 to move synchronously. When the driving inclined block 36 moves downward, as the control tooth plate 33 continues to move, the electromagnet can be powered off or separated from the limiting structure, so that the linkage control frame 2 slides on the control tooth plate 33 to avoid changes in the position of the adjustable traction wheel 24. No further details will be given here.

[0043] In one embodiment of the present invention, see Figure 1-Figure 13 The cooling control water tank section 4 includes an L-shaped water tank plate 1 27, an L-shaped water tank plate 28, a buffer support assembly, a synchronous pull rope 29, a push-pull smooth rod 30, a connecting rod 31 and a guide pulley 32; The L-shaped water tank plate 1 27 and the L-shaped water tank plate 2 28 are respectively connected to the wire drawing support frame 1 through two sets of buffer support components, and the L-shaped water tank plate 1 27 and the L-shaped water tank plate 2 28 are also inserted into the sealing tank plate 18 and are slidably connected to the sealing tank plate 18; Among them, the sealing groove plate 18, the L-shaped water groove plate 1 27 and the L-shaped water groove plate 2 28 form a U-shaped water groove structure; One end of the push-pull smooth rod 30 is fixedly connected to the L-shaped water tank plate 27, and the other end of the push-pull smooth rod 30 passes through one set of the buffer support assembly and is fixedly connected to the linkage control frame 2, and a connecting rod 31 is also fixedly installed on the push-pull smooth rod 30; The guide pulley 32 is rotatably mounted on another set of the buffer support assembly, one end of the synchronous pull rope 29 is fixedly connected to the connecting rod 31, and the other end of the synchronous pull rope 29 passes around the guide pulley 32, passes through another set of the buffer support assembly, and is fixedly connected to the L-shaped water tank plate 28.

[0044] The buffer support assembly comprises: Adjustment support plates 25, the number of the adjustment support plates 25 is two, the two adjustment support plates 25 are fixedly mounted on the wire drawing support frame 1, and are respectively located on both sides of the L-shaped water tank plate 1 27 and the L-shaped water tank plate 2 28; And the damping telescopic rods 26, the number of the damping telescopic rods 26 is four, two of which are connected to the adjusting support plate 25 and the L-shaped water tank plate 1 27 respectively, and the other two of the damping telescopic rods 26 are connected to another adjusting support plate 25 and the L-shaped water tank plate 2 28 respectively.

[0045] When the production demand requires manual adjustment of the position of the linkage control frame 2, during the movement of the linkage control frame 2, the linkage control frame 2 will pull the L-shaped water trough plate 1 27 to move toward the outer side of the sealing trough plate 18 through the push-pull smooth rod 30, and at the same time, pull the L-shaped water trough plate 2 28 in the opposite direction through the synchronous pull rope 29. At this time, the distance between the L-shaped water trough plate 1 27 and the L-shaped water trough plate 2 28 increases (if only one cooling control water trough section 4 is used, only the L-shaped water trough plate 1 27 and the L-shaped water trough plate 2 28 need to be sealed and slidably connected to the sealing trough plate 18. If multiple cooling control water trough sections 4 are used in combination to extend the consumable wire 6 Cooling time, in order to achieve better cooling effect, the adjacent L-shaped water trough plates 27 also need to be sealed and connected.
