[0012] As a preferred technical solution of the present invention, a cleaning component is installed on the wire drawing machine, and the surface of the solid welding wire is slidably connected inside the cleaning component. The cleaning component is used to alternately clean the surface of the solid welding wire. The cleaning component includes: a wire guide, which is fixed on the wire drawing machine and has four groups of sliding grooves on its surface; a sliding member, which is slidably connected inside the sliding groove and has a cleaning wheel installed on the end; an adjusting wheel, which is rotatably connected to the side of the wire guide and has two groups of arc grooves on its surface; a sliding shaft, which is fixed to the side of the four groups of sliding members, and two groups of sliding shafts are slidably connected in the two groups of arc grooves respectively.

[0013] As a preferred technical solution of the present invention, a wire feeding hole is provided on the wire guide, and an avoidance groove is provided on the adjusting wheel, and the wire feeding hole and the avoidance groove are connected.

[0014] A method for continuously drawing a solid welding wire comprises the following steps: Step 1: Pass the end of the solid welding wire through the wire feeding hole, the avoidance groove, the conical die and the wire drawing hole in the rotating die in sequence, and then wind it on the wire drawing tank; Step 2: Turn on the servo motor at the end of the wire drawing tank, so that the wire drawing tank draws the solid welding wire; Step 3: Turn on the driving part to rotate the rotary die to achieve uniform force on the solid welding wire in the circumferential direction; Step 4: Turn on the water pump in the cooling box to allow the coolant to cool the conical die and solid welding wire; Step 5: Rotate the adjusting wheel forward or backward so that the two sets of cleaning wheels clean the solid welding wire alternately, and at the same time clean the other two sets of cleaning wheels that are not clean, so as to achieve continuous wire drawing.

The water pump in the cooling box is turned on to allow the coolant to cool the conical die and the solid welding wire. At the same time, multiple groups of heat-conducting fins will slide out of the base in sequence and in an orderly manner under the action of the rotating assembly, so that the heat on the surface of the conical die and the rotary die can be successively discharged, reducing the local stress concentration caused by uneven cooling of the conical die and the rotary die, thereby meeting the production requirements of continuous wire drawing of solid welding wire.

[0016] When the heat-conducting fins slide out of the base, the oiling assembly will introduce the lubricant to the surface of the rotating mold under the pull of the heat-conducting fins, so as to lubricate the solid welding wire and the rotating mold, thereby reducing the friction coefficient between the solid welding wire and the rotating mold, reducing energy consumption and equipment wear, and improving mold precision and the surface finish of the solid welding wire.

[0027] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0028] The following describes the specific implementation of the present invention in detail in conjunction with specific embodiments.

[0029] See Figures 1 to 8 , a continuous wire drawing device for solid wire, comprising: A wire drawing machine 1, on which a base 11 is fixed. Inside the base 11, a conical die 12 is fixed and a rotating die 13 is rotatably connected. Wire drawing holes 120 are provided on both the conical die 12 and the rotating die 13. The conical die 12 and the rotating die 13 draw the solid wire 10 through the wire drawing holes 120. A wire drawing tank 14, rotatably connected to the wire drawing machine 1, and an end is connected to a servo motor that drives its rotation. A rotating assembly 2, rotatably connected to the side of the base 11 and connected to the rotating die 13, for driving the rotating die 13 to rotate inside the base 11. A cooling assembly 3, installed on the wire drawing machine 1, for cooling the conical die 12 and the rotating die 13. An unfolding assembly 4, provided on the surface of the rotating die 13 and slidably connected inside the base 11. To solve the heat dissipation problem inside the conical die 12 and the rotating die 13, the unfolding assembly 4 periodically slides out of the base 11 under the cooperation of the rotating die 13 to conduct the heat inside the conical die 12 and the rotating die 13. An oiling assembly 5, slidably connected inside the base 11, and an end is connected to the unfolding assembly 4, for cooperating with the unfolding assembly 4 to lubricate the conical die 12 and the rotating die 13.

[0030] In an embodiment of the present invention, as Figure 4 shown, the rotating assembly 2 includes: A fixing frame 21, connected to the base 11, and a driving member 22 is installed on the side. Among them, the driving member 22 is specifically a motor or a pneumatic motor. A driving gear 23, connected to the output end of the driving member 22. A gear ring 24, installed on the surface of the rotating die 13 and meshed with the driving gear 23.

[0031] In this embodiment, wire drawing (wire drawing) of the wire is a key process in the processing of the solid wire 10. The core is to gradually draw a thick metal blank into a thin wire through physical deformation. Utilizing the plastic properties of the metal material, an axial tensile force is applied at room temperature, so that the solid wire 10 undergoes plastic deformation through the wire drawing holes 120 of the conical die 12 and the rotating die 13. Among them, the conical die 12 and the rotating die 13 are made of cemented carbide or diamond dies.

[0032] Turn on the driving member 22. The output end of the driving member 22 will drive the rotary die 13 to rotate in the base 11 through the connection of the driving gear 23 and the gear ring 24. When the rotary die 13 rotates, the solid wire 10 will be evenly stressed in the circumferential direction, improving the surface finish of the solid wire and avoiding wear or scratches on the die surface caused by long-term friction between the die and the solid wire 10, which affects the uniformity of wire drawing of the solid wire 10.

[0033] Multiple wire drawing cans 14 are installed on the wire drawing machine 1, and a servo motor for driving its rotation is connected to the end of the wire drawing can 14. After the solid wire 10 is drawn by the conical die 12 and the rotary die 13, the drawn solid wire 10 is wound around the surface of the wire drawing can 14. The servo motor is turned on, and the multiple wire drawing cans 14 drive the solid wire 10 to be drawn. After being drawn by the multiple wire drawing cans 14, surface cracks and scratches can be reduced to ensure that the solid wire 10 is smooth and uniform.

[0034] In an embodiment of the present invention, as Figure 5 shown, the cooling assembly 3 includes: A cooling box 31, installed at the bottom of the wire drawing machine 1, with a water pump installed inside; A cooling pipe 32, one end of which is connected to the surface of the base 11, and the other end is communicated with the output end of the water pump; A nozzle 321, communicated with the end of the cooling pipe 32 far from the water pump; A water tank 33, connected to the side of the base 11.

[0035] In this embodiment, during the processing, the plastic deformation of the solid wire 10 will generate heat, which may cause material softening or oxidation. By turning on the water pump, the water pump can introduce the coolant in the cooling box 31 into the nozzle 321 through the cooling pipe 32, so that the coolant in the nozzle 321 is sprayed onto the surface of the conical die 12. The conical die 12 and the solid wire 10 during wire drawing are cooled by the coolant to ensure the quality and performance of the solid wire 10.

[0036] In an embodiment of the present invention, as Figure 1 and Figure 7 shown, the unfolding assembly 4 includes: Thermal conduction fins 41, slidably connected inside the base 11, and slidably connected to the surfaces of the conical die 12 and the rotary die 13. At least four groups of the thermal conduction fins 41 are installed.

[0037] A chute 43, opened on the surface of the rotary die 13; A convex groove 44, opened on the surface of the rotary die 13 and communicated with the chute 43; A sliding column 42, fixed to the side of the thermal conduction fin 41, and the end is slidably connected inside the chute 43 and the convex groove 44.

[0038] In this embodiment, during the processing, the heat generated during the plastic deformation of the conical die 12 and the rotary die 13 is transferred to the heat conducting fins 41. During the rotation of the rotary die 13, the sliding grooves 43 and the protruding grooves 44 on its surface will rotate synchronously, so that multiple sets of sliding columns 42 will slide in the sliding grooves 43 or the protruding grooves 44. When the sliding column 42 slides into the protruding groove 44, the sliding column 42 will drive the corresponding heat conducting fin 41 to slide out of the base 11 under the action of the protruding groove 44, so that the heat conducting fin 41 will be cooled under the action of the coolant, thereby the heat inside the rotary die 13 can be exported, so that the rotary die 13 can be cooled evenly and avoid only local cooling.

[0039] As Figure 6 shown, multiple sets of heat conducting fins 41 are provided, so that multiple sets of heat conducting fins 41 will slide out of the base 11 in sequence, thereby the heat on the surfaces of the conical die 12 and the rotary die 13 can be exported in sequence, reducing the local stress concentration caused by uneven cooling of the conical die 12 and the rotary die 13, so as to meet the continuous wire drawing production of the solid wire 10.

[0040] In an embodiment of the present invention, as Figure 6 and Figure 7 shown, the oil filling assembly 5 includes: A piston cylinder 51, fixed inside the base 11, with a piston member slidably connected therein. An oil inlet pipe 52 and an oil outlet pipe 53 are installed at the end of the piston cylinder 51, and one-way valves are installed in the oil inlet pipe 52 and the oil outlet pipe 53; A slide bar 54, slidably connected inside the piston cylinder 51, with one end connected to the piston member and the other end connected to a set of heat conducting fins 41; A flow channel 55, opened on the rotary die 13, and communicated with the wire drawing hole 120; An oil tank 56, installed on the wire drawing machine 1, and communicated with the piston cylinder 51 through the oil inlet pipe 52.

[0041] In this embodiment, during wire drawing, the high-pressure contact between the solid wire 10 and the conical die 12 and the rotary die 13 will cause intense friction, resulting in increased energy consumption and equipment wear. When the heat conducting fin 41 slides out of the base 11, the heat conducting fin 41 will pull the piston member to slide in the piston cylinder 51 through the slide bar 54; when the heat conducting fin 41 slides into the base 11, the heat conducting fin 41 will push the piston member to slide in the piston cylinder 51 in the reverse direction through the slide bar 54.

[0042] When the piston part slides back and forth in the piston cylinder 51, the one-way valves in the oil inlet pipe 52 and the oil outlet pipe 53 will open and close alternately. Thus, the lubricant in the fuel tank 56 will enter the piston cylinder 51 through the oil inlet pipe 52 and be discharged to the surface of the rotary die 13 through the oil inlet pipe 52 on the side of the piston cylinder 51, so as to lubricate between the rotary die 13 and the base 11. At the same time, the lubricant on the surface of the rotary die 13 will enter the wire drawing hole 120 through the flow channel 55, and then the solid wire 10 can be lubricated. By spraying the lubricant on the surface of the solid wire 10, the friction coefficient between the solid wire 10 and the rotary die 13 can be reduced, the energy consumption and equipment wear can be reduced, and the die accuracy and the surface finish of the wire can be improved.

[0043] In an embodiment of the present invention, as Figure 5 and Figure 8 shown, a cleaning assembly 6 is installed on the wire drawing machine 1, and the surface of the solid wire 10 is slidably connected inside the cleaning assembly 6. The cleaning assembly 6 is used for alternately cleaning the surface of the solid wire 10. The cleaning assembly 6 includes: A wire guide 61, fixed on the wire drawing machine 1, with four groups of sliding grooves 63 formed on its surface; A sliding member 64, slidably connected inside the sliding groove 63, with a cleaning wheel 65 installed at its end; An adjusting wheel 67, rotatably connected to the side of the wire guide 61, with two groups of arc-shaped grooves 68 formed on its surface. An inlet wire hole 62 is formed on the wire guide 61, and an avoidance groove 671 is formed on the adjusting wheel 67. The inlet wire hole 62 and the avoidance groove 671 are communicated.

[0044] A sliding shaft 66, fixed to the sides of the four groups of sliding members 64, and two groups of sliding shafts 66 are respectively slidably connected in the two groups of arc-shaped grooves 68.

[0045] In this embodiment, the contaminants on the surface of the solid wire 10 will increase the friction during wire drawing, resulting in wire breakage or surface defects. Before wire drawing the solid wire 10, the solid wire 10 is sequentially passed through the inlet wire hole 62 and the avoidance groove 671. During the wire drawing process, the surface of the solid wire 10 will be cleaned under the action of the cleaning wheel 65, so as to reduce the adhesion of metal chips on the surface of the solid wire 10 and ensure the smooth progress of the wire drawing process.

[0046] When it is necessary to clean the cleaning wheel 65, rotate the adjusting wheel 67, and the adjusting wheel 67 will drive the two groups of arc-shaped grooves 68 on its surface to rotate, as Figure 8As shown, when the adjusting wheel 67 drives the arc-shaped groove 68 to rotate, the two groups of sliding shafts 66 inside the arc-shaped groove 68 will drive the corresponding sliding members 64 to slide in the reverse direction in the sliding groove 63 under the action of the arc-shaped groove 68. Specifically, one group of sliding shafts 66 will drive the corresponding sliding members 64 to slide outward in the sliding groove 63 under the action of the arc-shaped groove 68, and the other group of sliding shafts 66 will drive the corresponding sliding members 64 to slide inward in the sliding groove 63 under the action of this group of arc-shaped grooves 68. Since there are four groups of sliding members 64 and cleaning wheels 65 respectively, when the two groups of cleaning wheels 65 in the horizontal direction approach each other, the two groups of cleaning wheels 65 in the vertical direction will move away from each other; similarly, when the two groups of cleaning wheels 65 in the vertical direction approach each other, the two groups of cleaning wheels 65 in the horizontal direction will move away from each other. Therefore, when the two groups of cleaning wheels 65 clean the solid wire 10, the two groups of cleaning wheels 65 that are away from each other can be cleaned at this time, improving the cleaning effect of the cleaning wheels 65 on the solid wire 10. The cleaning wheels 65 can be cleaned without stopping the machine, improving the continuity of the wire drawing of the solid wire 10, significantly enhancing the equipment stability and product quality, and at the same time reducing energy consumption and costs.

[0047] A continuous wire drawing method for solid wire, based on the above-mentioned continuous wire drawing device for solid wire, includes the following steps: Step 1: The end of the solid wire 10 is sequentially passed through the wire inlet hole 62, the avoidance groove 671, the conical die 12 and the wire drawing hole 120 in the rotary die 13, and then wound around the wire drawing tank 14. Step 2: Start the servo motor at the end of the wire drawing tank 14 to enable the wire drawing tank 14 to draw the solid wire 10. Step 3: Start the driving member 22 to enable the rotary die 13 to rotate, so as to achieve uniform force on the solid wire 10 in the circumferential direction. Step 4: Start the water pump in the cooling tank 31 to enable the coolant to cool the conical die 12 and the solid wire 10. Step 5: Rotate the adjusting wheel 67 forward or backward to enable the two groups of cleaning wheels 65 to alternately clean the solid wire 10, and at the same time clean the other two groups of unclean cleaning wheels 65 to achieve continuous wire drawing.

[0048] The working principle of the present invention is as follows: After the end of the solid wire 10 passes through the wire drawing holes 120 in the conical die 12 and the rotating die 13, the solid wire 10 undergoes plastic deformation through the wire drawing holes 120 of the conical die 12 and the rotating die 13. The rotating assembly 2 is started, causing the rotating die 13 to rotate on the base 11. When the rotating die 13 rotates, the force on the solid wire 10 in the circumferential direction will be uniform, improving the surface finish of the solid wire. The water pump in the cooling tank 31 is started, so that the coolant cools the conical die 12 and the solid wire 10. At the same time, under the action of the rotating assembly 2, multiple groups of heat conducting fins 41 will slide out of the base 11 in sequence, so that the heat on the surfaces of the conical die 12 and the rotating die 13 can be conducted out in sequence, reducing the local stress concentration caused by uneven cooling of the conical die 12 and the rotating die 13, thereby meeting the continuous wire drawing production of the solid wire 10.

[0049] In the description of the present invention, it should be noted that unless otherwise clearly specified and limited, the terms "installation", "connection", and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, an electrical connection, or a connection that can communicate with each other; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the internal communication of two components or the interaction relationship between two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0050] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
