DETAILED DESCRIPTION
[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0026] See also Figure 1-3A wire drawing machine in this embodiment includes a base 1, and a mechanism box 2 is fixed on the top of the base 1. It should be noted that a wire outlet is provided on the right side of the mechanism box 2, and the drawn metal wire will be pulled out from the wire outlet. A heating mechanism 3 that runs through the inside of the mechanism box 2 is fixed on the left side of the mechanism box 2, and a power box 4 is fixed on the rear side of the mechanism box 2. It should be noted that a plurality of ventilation holes are provided on the top and bottom of the power box 4. A large amount of heat will be generated during the operation of the mechanism. If the heat is not dissipated, the mechanism will operate at a high temperature, which will reduce the service life of the mechanism for a long time. The ventilation holes can connect the air inside and outside, dissipate the temperature through the flow of airflow, and extend its service life. A dust-proof and breathable mesh cover covering a plurality of ventilation holes is fixed on the top and bottom of the power box 4. The dust-proof and breathable mesh cover can block dust in the air flow process to prevent it from entering the inside of the mechanism and causing adverse effects on it.
[0027] In addition, a power motor 5 is fixed to the rear side wall of the inner cavity of the power box 4, and the output shaft of the power motor 5 faces forward. The output shaft of the power motor 5 is fixed with a driving shaft 6 that penetrates into the interior of the mechanism box 2 and is rotatably connected thereto. A driving wire drawing roller 7 is fixed to the outer surface of the driving shaft 6. A driven shaft 8 is rotatably connected between the front and rear side walls of the inner cavity of the mechanism box 2. A driven wire drawing roller 9 is fixed to the outer surface of the driven shaft 8. The driving wire drawing roller 7 and the driven wire drawing roller 9 are both composed of four rotating rollers with diameters ranging from large to small. The metal wire is cross-wound around the driving wire drawing roller 7 and the driven wire drawing roller 9, and cross-wraps around four wire drawing grooves of different sizes. The outer surfaces of the four rotating rollers are provided with wire drawing grooves corresponding to their diameters. The four wire drawing grooves on the driving wire drawing roller 7 and the driven wire drawing roller 9 are of different sizes, and their volumes are relatively consistent with the four rotating rollers with diameters ranging from large to small, and gradually decrease. The metal wire can be pulled back and forth in the wire drawing grooves on the driving wire drawing roller 7 and the driven wire drawing roller 9 by cross-winding, so that the diameter of the metal wire is continuously reduced and finally becomes a filament.
[0028] Furthermore, a grinding block 10 is fixed between the front and rear side walls of the inner cavity of the mechanism box 2. It should be noted that the grinding block 10 is located between the active wire drawing roller 7 and the driven wire drawing roller 9. It should be further noted that the grinding block 10 is composed of four grinding stones with lengths from large to small. The four grinding stones are respectively the first grinding stone, the second grinding stone, the third grinding stone and the fourth grinding stone. The grinding surfaces of the first grinding stone and the third grinding stone are facing upward, and the grinding surfaces of the second grinding stone and the fourth grinding stone are facing downward, and the pulled metal wire can be ground by the four grinding stones.
[0029] In addition, a duct 11 is fixed to the top of the mechanism box 2 and runs through the interior thereof. A dust blocking net is fixed to the top of the duct 11, which can block dust in the air and reduce the impact of dust on production. A fan 12 is fixed between the left and right side walls of the inner cavity of the duct 11. When the fan 12 is running, its blades rotate to stir the air and push it to form an airflow, sucking the air above into the mechanism box 2. A heating net 13 is fixed between the front and rear side walls of the inner cavity of the mechanism box 2 and is located below the fan 12. The heating net 13 can heat the air and heat the wind blown out by the fan 12 to become hot air. It should be noted that a collecting bucket 14 is fixed to the inner surface of the mechanism box 2. The vertical section of the collecting bucket 14 is funnel-shaped. A slag lowering opening is provided at the bottom of the collecting bucket 14, and the slag lowering opening allows metal debris to fall into the collecting box 15.
[0030] It should be noted that the right side of the mechanism box 2 is movably connected with a collection box 15 that penetrates into the interior thereof. The collection box 15 is located directly below the collection bucket 14. The fan 12 blows air downward so that the residue of the metal wire polished by the polishing block 10 can fall into the collection bucket 14 and be introduced into the collection box 15.
[0031] It should be noted that a handle is fixed on the right side of the collection box 15, which can provide a gripping point to facilitate pulling out the collection box 15. The vertical cross-section of the handle is U-shaped, and a non-slip rubber sleeve is fixed on the outer surface of the handle. The non-slip rubber sleeve can increase the friction of the outer surface and increase the pressure area of the hand by deformation, making the grip more firm and improving the grip comfort.
[0032] During operation, the heating mechanism 3 heats and shapes the metal wire so that it enters the wire drawing machine evenly after being heated, and gradually forms thin wires under the cooperation of the active wire drawing roller 7 and the driven wire drawing roller 9. It can be further subjected to constant temperature treatment by the fan 12 and the heating net 13, which can effectively eliminate the stress of the metal wire. The fan 12 blows air downward so that the residue of the metal wire polished by the polishing block 10 can fall into the collecting bucket 14 and be introduced into the collecting box 15.
[0033] See also Figure 4-5In order to heat and shape the metal wire, the heating mechanism 3 in this embodiment includes a heating tube 301 fixed on the left side of the mechanism box 2 and penetrating into the interior thereof, the left side of the heating tube 301 is threadedly connected with a wire feeder 302 penetrating into the interior thereof, a heating wire 303 is fixed on the inner surface of the heating tube 301, and the heating wire 303 generates a thermal magnetic field after being energized to heat the metal wire inside thereof and eliminate its stress, a rolling box 304 is fixed on the right side of the heating tube 301, and the top and bottom of the inner cavity of the rolling box 304 are fixed with a wire feeder 302 penetrating into the inner surface thereof. The external rolling component 305, it should be noted that the upper rolling component 305 includes a linkage rod 3051 fixed on the top of the inner cavity of the rolling box 304 and extending to the outside thereof, a limiting plate 3052 is fixed on the top of the linkage rod 3051, and the limiting plate 3052 plays a limiting role to prevent the linkage rod 3051 from detaching from the rolling box 304, and a mounting seat 3053 is fixed on the bottom of the linkage rod 3051, and the vertical section of the mounting seat 3053 is U-shaped. The two mounting seats 3053 are pressed away from each other, thereby squeezing the spring 3054.
[0034] It should be noted that a spring 3054 is fixed to the top of the mounting seat 3053, which is sleeved on the outside of the linkage rod 3051 and fixed to the rolling box 304. The spring 3054 is elastically deformed when squeezed and continues to accumulate elastic force. A rotating shaft 3055 is fixed to the inner side of the mounting seat 3053. The outer surface of the rotating shaft 3055 is rotatably connected to a rolling roller 3056. The upper and lower rolling rollers 3056 roll the heated metal wire under the elastic force of the spring 3054 to initially reduce its volume.
[0035] In general, the metal wire is fed into the heating tube 301 through the wire feed hopper 302, and the heating wire 303 heats the metal wire inside it to eliminate its stress, and passes through the two rolling rollers 3056. The two mounting seats 3053 are respectively subjected to the force from the two rolling rollers 3056 and move away from each other, thereby squeezing the spring 3054. The spring 3054 is elastically deformed by the squeezing and continuously accumulates elastic force. The upper and lower rolling rollers 3056 roll the heated metal wire under the elastic force of the spring 3054 to reduce its volume.
[0036] The electrical components appearing in the text are all electrically connected to the controller and the power supply. The control method of the utility model is controlled by the controller. The control circuit of the controller can be realized by simple programming by technicians in this field. The provision of power supply is also common knowledge in this field. The utility model is mainly used to protect mechanical devices, so the utility model will no longer explain the control method and circuit connection in detail.
[0037] The working principle of the above embodiment is:
[0038] During use, the metal wire is fed into the heating tube 301 through the wire feed hopper 302. After the heating wire 303 is energized, a thermal magnetic field is generated to heat the metal wire inside it, eliminate its stress, and pass through the two rolling rollers 3056. The two mounting seats 3053 are respectively subjected to the force from the two rolling rollers 3056 and move away from each other, thereby squeezing the spring 3054. The spring 3054 is elastically deformed by the squeezing and continues to accumulate elastic force. The upper and lower rolling rollers 3056 roll the heated metal wire under the elastic force of the spring 3054, and after initially reducing its volume, it is cross-wound around the active drawing roller 7 and the driven drawing roller 9, and cross-wraps inside four drawing grooves of different sizes. Driven by the power motor 5, its output shaft drives the active shaft 6 to rotate, and the active shaft 6 drives the active drawing roller 7 fixed on its outer surface to rotate, so that the metal wire The active wire drawing roller 7 and the driven wire drawing roller 9 are driven by four rotating rollers with diameters from large to small. The metal wire passes through the grinding surface on the top of the first grinding stone, the grinding surface on the bottom of the second grinding stone, the grinding surface on the top of the third grinding stone and the grinding surface on the bottom of the fourth grinding stone in turn to grind the pulled metal wire. The fan 12 is running, and its blades rotate to stir the air and push it to form an airflow, sucking the air above into the mechanism box 2. The heating net 13 heats the wind blown out by the fan 12 and turns it into hot air, further eliminating the stress generated by the metal wire during the pulling process. The residue of the metal wire polished by the grinding block 10 can fall into the collecting bucket 14 and is introduced into the collecting box 15. During the pulling process of the active wire drawing roller 7 and the driven wire drawing roller 9, the thickness of the metal wire gradually decreases, and finally becomes a thin wire and is discharged from the wire outlet, which can fully eliminate the stress and produce high-quality metal wire.
