Description

Technical Field

[0001] The invention relates to the technical field of wire drawing machines, in particular to a multi-head multi-drive high-speed wire drawing machine. Background Art

[0002] With the rapid development of my country's industry, the demand for metal wire, especially steel wire, is growing. As a highly efficient and energy-saving metal wire drawing equipment, multi-head multi-drive high-speed wire drawing machine plays an important role in steel wire production.

[0003] In existing wire drawing machines, the temperature of the steel wire will rise due to friction and tensile force during the high-speed drawing process. When the temperature is too high, the material properties of the steel wire change, microcracks are prone to appear, and then cause collapse. This not only affects the quality of the steel wire, but may also damage the wire drawing equipment and reduce production efficiency. During the production process, the steel wire is easily affected by environmental factors, such as dust. These impurities will adhere to the surface of the steel wire and enter the wire drawing die, causing the wire drawing die to be blocked and reducing the wire drawing efficiency. Summary of the invention

[0004] In view of the shortcomings of the prior art, the present invention provides a multi-head and multi-drive high-speed wire drawing machine, which solves the problem of micro cracks caused by increased temperature and clogging of the wire drawing die caused by dust and impurities when the existing wire drawing machine draws steel wire at high speed, which seriously affects the quality of the steel wire and production efficiency.

[0007] The wire drawing head includes flange plate 1 and flange plate 2 which are arranged on the outside of the wire drawing head. An annular oil storage bag is arranged on the side of flange plate 1 close to flange plate 2. The oil storage bag is fixedly sleeved on the outside of the wire drawing head, and a spiral memory alloy is sleeved on the outside of the wire drawing head between the oil storage bag and flange plate 2. The two ends of the spiral memory alloy are respectively connected to flange plate 2 and one side of the oil storage bag. A plurality of trapezoidal oil leakage holes are arranged on the inner side of the oil storage bag. The trapezoidal oil leakage holes are communicated with the interior of the wire drawing head, and the inner edge of the oil storage bag is covered with a layer of filter membrane.

[0008] Preferably, the spiral memory alloy will undergo elongation deformation when the temperature is above 50 degrees, and return to its original state when the temperature is below 50 degrees. In the original state, the spiral memory alloy exerts no pressure on the oil storage bag, and the deformation amount of the spiral memory alloy is proportional to the temperature change.

[0009] Preferably, the wire drawing head is made of a heat-conducting material.

[0010] Preferably, the small pore size of the oil storage bag faces the filter membrane, and when the oil storage bag is not under pressure, the lubricating oil in the oil storage bag cannot flow out from the oil leakage hole due to surface tension. When the oil storage bag is under pressure, the lubricating oil in the oil storage bag flows out from the oil leakage hole.

[0011] Preferably, a through hole is provided at the bottom of the oil storage bag, a hard pipe head is integrally formed at the through hole, a cover plate is hinged on the upper part of the hard pipe head, the bottom of the cover plate and the inner side of the hard pipe head are connected by a tension spring, and when the tension spring is in the reset state, the cover plate just seals and covers the hard pipe head.

[0012] Preferably, the oil delivery mechanism includes an oil tank, and limit seats are arranged on the upper parts of both sides of the oil tank. A limit tube is connected between the two limit seats. The lubricating oil inside the oil tank is drawn into the limit tube through a built-in pump, and a plurality of branch tubes corresponding to each drawing head are arranged on the limit tube, and the other end of the branch tube is connected to the lower end of the hard tube head on the oil storage bag.

[0013] Preferably, the unwinding mechanism includes unwinding mounting seats arranged at the two upper edges of the base, an unwinding shaft is rotatably arranged between the two unwinding mounting seats, and a plurality of unwinding wheels corresponding to each wire drawing head are arranged outside the unwinding shaft.

[0015] The present invention provides a multi-head multi-drive high-speed wire drawing machine, which has the following beneficial effects compared with the prior art:

[0016] 1. This multi-head multi-drive high-speed wire drawing machine uses the temperature-sensitive characteristics of spiral memory alloy to achieve adaptive control of the lubrication system. When the friction heat generated during the metal wire drawing process exceeds 50 degrees, the spiral memory alloy deforms and elongates, automatically increasing the internal pressure of the oil storage bag, causing the lubricating oil to overflow from the oil leakage hole to lubricate the metal wire. When the temperature drops, the spiral memory alloy returns to its original state and the lubrication system automatically stops working, effectively avoiding excessive consumption and waste of lubricating oil.

[0017] 2. The multi-head multi-drive high-speed wire drawing machine realizes the closed replenishment of the lubricating oil inside the oil storage bag through the coordinated use of the oil tank and the pump. The cover is pushed open when replenishing the lubricating oil by using the mechanism of the hard pipe head and the tension spring, and automatically resets after the replenishment is completed, thereby ensuring the closedness of the lubrication system and preventing the leakage and contamination of the lubricating oil. In addition, when the oil storage bag is squeezed, the cover can more tightly close the hard pipe head to prevent the lubricating oil from flowing back into the oil tank.

[0018] 3. The multi-head multi-drive high-speed wire drawing machine realizes the eccentric movement of the eccentric rod through the linkage of the unwinding shaft and the turntable, thereby driving the guide plate to move back and forth on the guide shaft. The cleaning brush at the bottom of the guide plate can continuously wipe the metal wire and clean the metal wire, which not only helps to improve the surface quality of the metal wire, but also reduces the friction and wear caused by dirt on the surface of the metal wire, thereby improving the wire drawing efficiency and product quality.

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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.

[0027] See also Figure 1-Figure 6 , the present invention provides three technical solutions:

[0028] Embodiment 1

[0029] See also Figure 1 In an embodiment of the present invention, a multi-head multi-drive high-speed wire drawing machine includes a base 1, and an unwinding mechanism 2 and a wire drawing mechanism 3 are respectively arranged on the upper parts of both sides of the base 1, and a self-lubricating and cleaning mold mechanism 4 is arranged at the upper part of the base 1 between the unwinding mechanism 2 and the wire drawing mechanism 3.

[0030] See also Figure 2 In the embodiment of the present invention, the self-lubricating and cleaning mold mechanism 4 includes a limiting plate 41, a plurality of drawing heads 42 are arranged through one side of the limiting plate 41, a self-lubricating mechanism 43 is arranged outside one end of the drawing head 42, and an oil supply mechanism 44 is arranged at the lower part of one side of the limiting plate 41.

[0031] See also Figure 2-Figure 4In the embodiment of the present invention, the wire drawing head 42 includes a flange plate 1 431 and a flange plate 2 433 arranged on the outside of the wire drawing head 42, and a ring-shaped oil storage bag 432 is arranged on the side of the flange plate 1 431 close to the flange plate 2 433, and the oil storage bag 432 is fixedly sleeved on the outside of the wire drawing head 42, and a spiral memory alloy 434 is sleeved on the outside of the wire drawing head 42 between the oil storage bag 432 and the flange plate 2 433, and the two ends of the spiral memory alloy 434 are respectively connected to the flange plate 2 433 and one side of the oil storage bag 432, and a plurality of trapezoidal oil leakage holes 435 are arranged on the inner side of the oil storage bag 432, and the trapezoidal oil leakage holes 435 are communicated with the interior of the wire drawing head 42, and the inner edge of the oil storage bag 432 is covered with a layer of filter membrane 436.

[0032] See also Figure 2-Figure 4 In the embodiment of the present invention, the spiral memory alloy 434 will undergo elongation deformation when the temperature is above 50 degrees, and will return to its original state when the temperature is below 50 degrees. In the original state, the spiral memory alloy 434 has no pressure on the oil storage bag 432, and the deformation of the spiral memory alloy 434 is proportional to the change in temperature.

[0033] See also Figure 2-Figure 4 In the embodiment of the present invention, the small aperture of the oil storage capsule 432 faces the filter membrane 436, and when the oil storage capsule 432 is not under pressure, the lubricating oil in the oil storage capsule 432 cannot flow out from the oil leakage hole 435 due to surface tension. When the oil storage capsule 432 is under pressure, the lubricating oil in the oil storage capsule 432 flows out from the oil leakage hole 435.

[0034] In the above scheme: during wire drawing, the metal will generate heat due to friction in the drawing hole of the drawing head 42, and the heat will be transferred to the spiral memory alloy 434. When the heat exceeds 50 degrees, the spiral memory alloy 434 will deform and elongate, thereby pressing the oil storage bag 432 to increase its internal pressure. The lubricating oil inside the oil storage bag 432 overflows from the oil leakage hole 435, is filtered through the filter membrane 436, and then drips onto the metal wire to lubricate the metal wire. The higher the friction temperature, the greater the deformation force of the spiral memory alloy 434, the oil output will increase, and the lubrication effect will be improved. When the friction temperature is lower than 50 degrees, the spiral memory alloy 434 will return to its original state and no longer press the oil storage bag 432. At this time, the pressure in the oil storage bag 432 returns to normal, and the lubricating oil cannot flow out of the oil leakage hole 435 due to tension, and the metal wire stops being lubricated.

[0035] For further information, see Figure 2-Figure 4 In the embodiment of the present invention, the wire drawing head 42 is made of a heat-conducting material. The heat generated by the friction of the metal wire can be transferred to the spiral memory alloy 434, causing it to deform and thus achieve lubrication of the metal wire. The heat-conducting material is preferably copper.

[0036] The second embodiment is different from the first embodiment in that:

[0037] See also Figure 4-Figure 5 In the embodiment of the present invention, a through hole 4321 is provided at the bottom of the oil storage bag 432, and a hard pipe head 4322 is integrally formed at the through hole 4321. A cover plate 4323 is hinged on the upper part of the hard pipe head 4322. The bottom of the cover plate 4323 is connected to the inner side of the hard pipe head 4322 through a tension spring 4324. When the tension spring 4324 is in the reset state, the cover plate 4323 just seals and covers the hard pipe head 4322.

[0038] See also Figure 4-Figure 5 In the embodiment of the present invention, the oil delivery mechanism 44 includes an oil tank 441, and limit seats 442 are arranged on the upper parts of both sides of the oil tank 441. A limit tube 443 is connected between the two limit seats 442. The lubricating oil inside the oil tank 441 is drawn into the limit tube 443 through a built-in pump, and a plurality of branch tubes 444 corresponding to each drawing head 42 are arranged on the limit tube 443, and the other end of the branch tube 444 is connected to the lower end of the hard tube head 4322 on the oil storage bag 432.

[0039] In the above scheme: when it is necessary to add lubricating oil to the oil storage bag 432, the pump inside the oil tank 441 draws the lubricating oil into the branch pipe 444 through the limit tube 443, and then the lubricating oil passes through the hard pipe head 4322, and under the elasticity of the tension spring 4324, the cover plate 4323 is pushed upward to add lubricating oil to the oil storage bag 432. After the replenishment is completed, the pump is stopped. At this time, the tension spring 4324 restores the cover plate 4323 to its initial position and covers the hard pipe head 4322. When the oil storage bag 432 is squeezed, the lubricating oil in the oil storage bag 432 will generate pressure on the upper part of the cover plate 4323, so that the cover plate 4323 covers the hard pipe head 4322 more tightly, so that the lubricating oil will not enter the oil tank 441, but will wet the metal wire through the oil leakage hole 435.

[0040] Embodiment 3 is different from Embodiment 1 in that:

[0041] See also Figure 1 and Figure 6 In the embodiment of the present invention, the unwinding mechanism 2 includes an unwinding mounting seat 21 arranged at the two upper edges of the base 1, an unwinding shaft 22 is rotatably arranged between the two unwinding mounting seats 21, and a plurality of unwinding wheels 23 corresponding to each wire drawing head 42 are arranged outside the unwinding shaft 22. The wire drawing mechanism 3 includes a wire drawing mounting seat 31 arranged at the two upper edges of the base 1, a wire drawing shaft 32 is rotatably arranged between the two wire drawing mounting seats 31, and a plurality of wire drawing wheels 33 corresponding to each wire drawing head 42 are arranged outside the wire drawing shaft 32, and a wire drawing motor 34 for driving the wire drawing shaft 32 to rotate is installed on one side of one of the wire drawing mounting seats 31.

[0042] See also Figure 1and Figure 6 In the embodiment of the present invention, the multi-head multi-drive high-speed wire drawing machine also includes a self-cleaning mechanism 5 for cleaning the metal wire. The self-cleaning mechanism 5 includes two turntables 54 that are rotatably arranged on the opposite sides of the two unwinding mounting seats 21 and two guide shafts 51 that are respectively connected to the two corners of one side of the limiting plate 41. A guide plate 52 is provided for transverse sliding between the outsides of the two guide shafts 51. A plurality of cleaning brushes 53 corresponding to each drawing head 42 are provided at the bottom of the guide plate 52. Eccentric rods 55 are hinged at the edges of the opposite sides of the two turntables 54, and the other ends of the two eccentric rods 55 are hinged to the two ends of the guide plate 52 respectively.

[0043] In the above scheme: when drawing the wire, the unwinding shaft 22 will rotate, thereby driving the turntable 54 to rotate, and the turntable 54 causes the eccentric rod 55 to make an eccentric movement, and the eccentric rod 55 will drive the guide plate 52 to move back and forth on the guide shaft 51, and the cleaning brush 53 at the bottom of the guide plate 52 will continuously wipe the metal wire to clean the metal wire.

[0044] Working principle: The metal coils to be drawn are respectively mounted on the respective drawing wheels 33, and then one end of the metal coil is passed through the drawing hole of the drawing head 42 and fixed to the corresponding drawing wheel 33, and then the drawing motor 34 drives the drawing wheels 33 on the drawing shaft 32 to rotate, and each drawing wheel 33 performs drawing operation on each metal respectively;

[0045] During wire drawing, the metal will generate heat by friction in the drawing hole of the drawing head 42, and the heat will be transferred to the spiral memory alloy 434. When the heat exceeds 50 degrees, the spiral memory alloy 434 will deform and elongate, thereby pressing the oil storage capsule 432 to increase the internal pressure. The lubricating oil in the oil storage capsule 432 will overflow from the oil leakage hole 435, and after being filtered by the filter membrane 436, it will drip onto the metal wire to lubricate the metal wire. The higher the friction temperature, the greater the deformation of the spiral memory alloy 434, the greater the oil output, and the improved lubrication effect. When the friction temperature is lower than 50 degrees, the spiral memory alloy 434 will return to its original state and no longer press the oil storage capsule 432. At this time, the pressure in the oil storage capsule 432 returns to normal, and the lubricating oil cannot flow out of the oil leakage hole 435 due to tension, and the metal wire stops being lubricated.

[0046] When it is necessary to add lubricating oil to the oil storage bag 432, the pump inside the oil tank 441 draws the lubricating oil into the branch pipe 444 through the limit pipe 443, and then the lubricating oil passes through the hard pipe head 4322, and under the elasticity of the tension spring 4324, the cover plate 4323 is pushed upward to add lubricating oil to the oil storage bag 432. After the replenishment is completed, the pump stops working, and the tension spring 4324 restores the cover plate 4323 to its initial position to cover the hard pipe head 4322. When the oil storage bag 432 is squeezed, the lubricating oil in the oil storage bag 432 will generate pressure on the upper part of the cover plate 4323, so that the cover plate 4323 covers the hard pipe head 4322 more tightly, so that the lubricating oil will not enter the oil tank 441, but will wet the metal wire through the oil leakage hole 435;

[0047] When drawing the wire, the unwinding shaft 22 will rotate, thereby driving the turntable 54 to rotate. The turntable 54 causes the eccentric rod 55 to make an eccentric movement, and the eccentric rod 55 will drive the guide plate 52 to move back and forth on the guide shaft 51. The cleaning brush 53 at the bottom of the guide plate 52 will continuously wipe the metal wire to clean the metal wire.
