Description

Technical Field

[0001] This invention belongs to the field of other non-ferrous metal rolling processing, specifically a metal wire rolling processing device. Background Technology

[0002] Metal wire drawing is an important metal processing technology, belonging to the category of non-ferrous metal rolling. By drawing metal wire, the microstructure and mechanical properties of the metal wire can be improved, thereby producing high-strength metal wire with superior performance. Currently, metal wire drawing is generally processed by rolling equipment, which is both high-quality and efficient.

[0003] Patent CN115446136B discloses a high-strength tungsten alloy ultra-fine wire drawing device, including a traction structure. The traction structure includes a linear guide rail, on which a clamp is fixedly installed. An external electromagnetic coil is installed inside the clamp and is sleeved on the linear guide rail. An inner winding piston is slidably mounted on the linear guide rail, and an internal electromagnetic coil is installed inside the inner winding piston. A gripper for clamping the metal wire is fixedly installed on the inner winding piston. An electromagnetic valve is installed on the gripper, and an eye mold is located in front of the gripper. This solution uses the electromagnetic valve to open and close the gripper, thereby fixing the metal wire on the gripper. The traction structure drives the gripper to move back and forth, realizing the drawing of the metal wire after passing through the mold, thus obtaining a high-strength metal wire. Since the traction structure is driven by electromagnetic means, sliding friction is avoided, improving the surface quality of the metal wire.

[0004] In the above-mentioned scheme, the metal wire is pulled by the gripper driven by the traction structure. During this process, when changing the position of the gripper holding the metal wire, the operator needs to pull the metal wire to achieve the gripper holding the metal wire. The operation is troublesome and time-consuming, which reduces the metal wire pulling efficiency. Therefore, the present invention provides a metal wire rolling processing device. Summary of the Invention

[0005] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0006] The technical solution adopted by the present invention to solve its technical problem is as follows: The present invention provides a metal wire rolling processing device, including a base, a traction mechanism on the base, a drawing mechanism for drawing metal wire on the traction mechanism, a die in front of the drawing mechanism, a reel behind the drawing mechanism, the reel being rotatably mounted on a support, a motor for driving the reel being fixedly mounted on the support, the drawing mechanism including a movable seat, the movable seat being fixedly mounted on the traction mechanism, a clamp hinged to the movable seat, one end of the clamp hinged to the upper end of a cylinder, the movable seat hinged to the lower end of the cylinder, and a clamping piece below the other end of the clamp, the clamping piece being fixedly mounted on the movable seat;

[0007] By coordinating the reel and the drawing mechanism, the metal wire remains taut throughout the drawing process, ensuring that the drawing mechanism can accurately clamp the metal wire when changing clamping positions. This not only improves the automation efficiency of the device but also increases the efficiency of metal wire drawing.

[0008] Preferably, the pulling mechanism further includes a slider, which is fixedly mounted on the bottom surface of the movable seat, and the slider is slidably connected to a slide rail, which is fixedly mounted on a support frame, and the support frame is fixedly mounted on a base.

[0009] Specifically, during the process of the traction mechanism driving the pulling mechanism to pull the metal wire, the movable seat will drive the slider to slide along the slide rail. The cooperation between the slider and the slide rail guides the movement of the pulling mechanism.

[0010] Preferably, a take-up mechanism is provided between the drawing mechanism and the reel. The take-up mechanism includes a fixed frame, which is fixedly installed on the base. Two sets of guide wheels are rotatably installed on the fixed frame. The metal wire passes between the two sets of guide wheels. A first gear is installed at the end of one set of guide wheels, and a drive shaft is connected to the end of the other set of guide wheels. A second gear is fixedly mounted on the drive shaft. The second gear meshes with the first gear. A third gear is rotatably mounted on the drive shaft. Several sets of teeth are arranged around one side of the second gear. One end of the pawl engages with the teeth. The other ends of the four sets of pawls are all hinged to one end face of the third gear. A rack is fixedly connected to one end of the movable seat. The rack meshes with the third gear. Four sets of locking blocks are provided on the other end face of the third gear. All four sets of locking blocks mesh with the chuck. Two sets of guide posts are connected to one side of the chuck. The guide posts are inserted into the support. The chuck is movably mounted on the drive shaft. One end of the drive shaft is rotatably connected to the support. The lower end of the support is fixedly connected to the fixed frame. A first spring is provided between the support and the third gear. Four sets of locking slots are provided at equal angles on the chuck. The four sets of locking blocks respectively engage the four sets of locking slots.

[0011] Under the rebound force of the first spring, the locking block repeatedly squeezes the chuck until the pulling mechanism moves back towards the eye mold. During the backward movement, the reel winds up the metal wire until it is straightened. At the same time, because the pawl cannot engage the corresponding teeth, and under the locking force of the locking block and the slot, the second gear cannot rotate. The two sets of guide wheels will not continue to transmit the metal wire. Since the take-up mechanism can synchronously transmit the metal wire with the feed amount of the traction mechanism during the metal wire pulling process, it avoids the metal wire being pulled too tight or too loose, thus improving the pulling efficiency of the metal wire.

[0012] Preferably, the take-up mechanism further includes a buffer mechanism, which includes a fixed plate, the fixed plate being fixedly mounted on a fixed frame, two sets of slide rods being fixedly mounted on the fixed plate, a movable arm slidably connecting the two sets of slide rods, a roller rotatably mounted at the end of the movable arm, and a second spring being provided between the movable arm and the fixed plate, with the roller rollingly connecting the metal wire.

[0013] The roller pushes the movable arm upward along the slide bar until the second spring is in a semi-compressed state. At this point, if the winding amount of the reel is greater than the wire pulling amount, the movable arm will continue to move upward from the initial state, further compressing the second spring in its semi-compressed state. If the winding amount of the reel is less than the wire pulling amount, the movable arm will continue to move downward from the initial state. Therefore, under the action of the second spring's rebound force, the wire is kept taut while ensuring it does not break, providing a certain correction space for the reel winding amount error and ensuring that the wire pulling can proceed normally.

[0014] The beneficial effects of this invention are as follows:

[0015] 1. By coordinating the reel and the drawing mechanism, the metal wire remains taut throughout the drawing process, ensuring that the drawing mechanism can accurately clamp the metal wire when changing clamping positions. This not only improves the automation efficiency of the device but also increases the efficiency of metal wire drawing.

[0016] 2. During the wire drawing process of the drawing mechanism, the reel does not rewind the wire. The movable seat pushes the rack to move, and the moving rack drives the third gear to rotate. The third gear drives the four sets of pawls to rotate. Since the pawls abut against the corresponding teeth, the pawls cause the second gear to rotate through the teeth. The second gear drives the transmission shaft and the corresponding guide wheel to rotate together. At the same time, the second gear drives another set of guide wheels to rotate through the first gear. The two sets of guide wheels rotating synchronously convey the wire towards the reel, causing the wire to accumulate between the reel and the take-up mechanism. During this process, the four sets of clamps rotate together with the third gear, and the clamps squeeze... Under the rebound force of the first spring, the chuck on the pressure chuck repeatedly squeezes the chuck until the pulling mechanism moves back towards the eye mold. During the backward movement, the reel winds up the metal wire until it is straightened. At the same time, because the pawl cannot engage the corresponding teeth, and under the engaging force of the chuck and the slot, the second gear cannot rotate. The two sets of guide wheels will not continue to feed the metal wire. Since the take-up mechanism can synchronously feed the metal wire with the feed amount of the traction mechanism during the wire pulling process, it avoids the metal wire being pulled too tight or too loose, thus improving the wire pulling efficiency.

[0017] 3. When the metal wire is being drawn, two sets of guide wheels convey the wire towards the reel. The wire will disengage from the rollers and, under the rebound force of the second spring, the movable arm moves downward along the slide bar. When the reel winds up the wire, the wire re-enters contact the rollers and pushes them upward, causing the rollers to push the movable arm upward along the slide bar until the second spring is in a semi-compressed state. If the reel winding amount is greater than the wire drawing amount, the movable arm will continue to move upward from its initial state, further compressing the semi-compressed second spring. If the reel winding amount is less than the wire drawing amount, the movable arm will continue to move downward from its initial state. Therefore, under the rebound force of the second spring, the wire is kept taut while ensuring it does not break, providing a certain correction space for the reel winding amount error and ensuring that the wire drawing can proceed normally.

[0028] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0029] Example 1: As Figure 1 and Figure 2 As shown in the embodiment of the present invention, a metal wire rolling processing device includes a base 1, a traction mechanism 2 is provided on the base 1, a drawing mechanism 3 for drawing metal wire 4 is provided on the traction mechanism 2, a die 5 is provided in front of the drawing mechanism 3, a reel 6 is provided behind the drawing mechanism 3, the reel 6 is rotatably mounted on a bracket 7, a motor 8 for driving the reel 6 is fixedly mounted on the bracket 7, the drawing mechanism 3 includes a movable seat 301, the movable seat 301 is fixedly mounted on the traction mechanism 2, a clamp 302 is hinged to the movable seat 301, one end of the clamp 302 is hinged to the upper end of the cylinder 303, the lower end of the cylinder 303 is hinged to the movable seat 301, and a clamping piece 304 is provided below the other end of the clamp 302, the clamping piece 304 is fixedly mounted on the movable seat 301.

[0030] Specifically, the traction mechanism 2 adopts the structure corresponding to the high-strength tungsten alloy ultra-fine wire drawing device in the aforementioned announcement number CN115446136B. In the initial state, the drawing mechanism 3 is close to the eye mold 5, and the clamp 302 is in the open state. When it is necessary to draw the metal wire 4, the metal wire 4 is passed through the eye mold 5, and then the end of the metal wire 4 is clamped by pliers for drawing, and the metal wire 4 is passed between the other end of the clamp 302 and the clamping plate 304 until the metal wire 4 is wound on the reel 6. Then, the cylinder 303 is activated, and the cylinder 303 pushes the clamp 302 upward, so that the metal wire 4 is clamped between the other end of the clamp 302 and the clamping plate 304. Then, the traction mechanism 2 drives the drawing mechanism 3 to draw the metal wire. The wire 4 is drawn. During the drawing process, the synchronously started motor 8 drives the reel 6 to wind the metal wire 4. The winding amount of the reel 6 on the metal wire 4 is consistent with the drawing amount of the drawing mechanism 3 on the metal wire 4, so that the metal wire 4 is always in a taut state. Therefore, the drawing mechanism 3 is repeatedly moved by the traction mechanism 2, so that the drawing mechanism 3 repeatedly draws the metal wire 4, thereby realizing automatic drawing of the metal wire 4. Compared with the existing technology, through the cooperation of the reel 6 and the drawing mechanism 3, the metal wire 4 is always in a taut state during the drawing process. This ensures that the drawing mechanism 3 can accurately clamp the metal wire 4 when changing the clamping position, which not only improves the automation efficiency of the device, but also improves the drawing efficiency of the metal wire 4.

[0031] Furthermore, the pulling mechanism 3 also includes a slider 305, which is fixedly installed on the bottom surface of the movable seat 301. The slider 305 is slidably connected to the slide rail 306, which is fixedly installed on the support frame 307, and the support frame 307 is fixedly installed on the base 1.

[0032] Specifically, during the process of the traction mechanism 2 driving the pulling mechanism 3 to pull the metal wire 4, the movable seat 301 will drive the slider 305 to slide along the slide rail 306. The cooperation between the slider 305 and the slide rail 306 plays a guiding role in the movement of the pulling mechanism 3.

[0033] like Figures 3 to 6As shown, a take-up mechanism 9 is provided between the drawing mechanism 3 and the reel 6. The take-up mechanism 9 includes a fixed frame 901, which is fixedly mounted on the base 1. Two sets of guide wheels 902 are rotatably mounted on the fixed frame 901. The metal wire 4 passes between the two sets of guide wheels 902. A first gear 903 is mounted on the end of one set of guide wheels 902, and a drive shaft 904 is connected to the end of the other set of guide wheels 902. A second gear 905 is fixedly mounted on the drive shaft 904 and meshes with the first gear 903. A third gear 906 is rotatably mounted on the drive shaft 904. Several sets of teeth 907 are arranged around one side of the second gear 905. One end of a pawl 908 engages with the teeth 907. There are four sets of pawls 908. The other end is hinged to one end face of the third gear 906. One end of the movable seat 301 is fixedly connected to the rack 3011, which meshes with the third gear 906. Four sets of locking blocks 909 are provided on the other end face of the third gear 906. All four sets of locking blocks 909 mesh with the chuck 910. Two sets of guide posts 912 are connected to one side of the chuck 910. The guide posts 912 are inserted into the support 913. The chuck 910 is movably mounted on the transmission shaft 904. One end of the transmission shaft 904 is rotatably connected to the support 913. The lower end of the support 913 is fixedly connected to the fixing frame 901. A first spring 911 is provided between the support 913 and the third gear 906. Four sets of slots 11 are provided at equal angles on the chuck 910. The four sets of locking blocks 909 respectively engage the four sets of slots 11.

[0034] Specifically, the pawl 908 is made of magnet material, and it has an attractive force on the teeth 907 and the second gear 905. During the drawing process of the drawing mechanism 3, the amount of winding of the metal wire 4 by the reel 6 needs to be precisely controlled to ensure that the metal wire 4 is neither too tight nor too loose. However, in actual operation, there is a certain error between the feed amount of the traction mechanism 2 and the rotation amount of the reel 6. This can easily lead to the metal wire 4 breaking or becoming too loose, affecting the drawing efficiency of the metal wire 4. Therefore, during the drawing process... During the process of mechanism 3 drawing the metal wire 4, the reel 6 does not wind the metal wire 4. The movable seat 301 pushes the rack 3011 to move. The moving rack 3011 drives the third gear 906 to rotate. The third gear 906 drives the four sets of pawls 908 to rotate. Since the pawls 908 abut against the corresponding teeth 907, the pawls 908 cause the second gear 905 to rotate through the teeth 907. The second gear 905 drives the transmission shaft 904 to rotate together with the corresponding guide wheel 902. At the same time, the second gear 905 drives the first gear 904 to rotate through the first gear 905. 03 drives another set of guide wheels 902 to rotate. The two sets of guide wheels 902 rotating synchronously convey the metal wire 4 towards the reel 6, causing the metal wire 4 to accumulate between the reel 6 and the take-up mechanism 9. During this process, the four sets of clamping blocks 909 rotate together with the third gear 906. The clamping blocks 909 press the clamping slots 11 on the chuck 910. Under the rebound force of the first spring 911, the clamping blocks 909 repeatedly press the chuck 910 until the pulling mechanism 3 moves back towards the eye mold 5. During the backward movement... The reel 6 winds up the metal wire 4 until it is straight. At the same time, because the pawl 908 cannot engage the corresponding tooth 907, and because the second gear 905 cannot rotate under the engaging force of the locking block 909 and the locking groove 11, the two sets of guide wheels 902 will not continue to feed the metal wire 4. Since the winding mechanism 9 can synchronously feed the metal wire 4 with the feed amount of the traction mechanism 2 during the pulling process, it avoids the metal wire 4 being pulled too tight or too loose, thus improving the pulling efficiency of the metal wire 4.

[0035] Example 2: Figure 7 and Figure 8 As shown in the comparative embodiment one, another embodiment of the present invention is as follows: the take-up mechanism 9 further includes a buffer mechanism 914, the buffer mechanism 914 includes a fixed plate 41, the fixed plate 41 is fixedly installed on the fixed frame 901, two sets of slide rods 42 are fixedly installed on the fixed plate 41, the movable arm 43 of the two sets of slide rods 42 is slidably connected, the roller 45 is rotatably installed at the end of the movable arm 43, a second spring 44 is provided between the movable arm 43 and the fixed plate 41, and the roller 45 is rotatably connected to the metal wire 4.

[0036] Specifically, the distance that the drawing mechanism 3 draws the metal wire 4 each time is constant. Therefore, as long as the number of rotations of the reel 6 is controlled, the winding amount of the reel 6 and the drawing amount of the metal wire 4 can be kept consistent. However, in actual operation, there will be errors in the winding amount of the reel 6. If the winding amount is greater than the drawing amount of the metal wire 4, the metal wire 4 will be pulled too tightly, causing the metal wire 4 to break. If the winding amount is less than the drawing amount of the metal wire 4, the metal wire 4 will be slack. When the metal wire 4 is taut, the roller 45 is in close contact with the metal wire 4, and the second spring 44 is in a semi-compressed state. When the metal wire 4 is drawn, the two sets of guide wheels 902 will transmit the metal wire 4 towards the reel 6. The metal wire 4 will detach from the contact with the roller 45. Under the rebound force of the second spring 44, the movable arm 43 moves along the slide bar 4. 2. Moving downwards, when the reel 6 winds up the metal wire 4, the metal wire 4 comes into contact with the roller 45 again, and will squeeze the roller 45 to move upwards, causing the roller 45 to push the movable arm 43 to move upwards along the slide bar 42 until the second spring 44 is in a semi-compressed state. At this time, if the winding amount of the reel 6 is greater than the pulling amount of the metal wire 4, the movable arm 43 will continue to move upwards from the initial state, so that the second spring 44 in the semi-compressed state is further compressed. If the winding amount of the reel 6 is less than the pulling amount of the metal wire 4, the movable arm 43 will continue to move downwards from the initial state. Therefore, under the action of the rebound force of the second spring 44, the metal wire 4 is kept taut while ensuring that it does not break, giving the reel 6 a certain correction space for the winding amount error, and ensuring that the metal wire 4 can be pulled normally.

[0037] Working principle: The metal wire 4 is passed through the eye mold 5, and then the end of the metal wire 4 is clamped by pliers and pulled, so that the metal wire 4 passes between the other end of the clamp 302 and the clamping plate 304 until the metal wire 4 is wound on the reel 6. Then, the cylinder 303 is started, and the cylinder 303 pushes the clamp 302 upward, so that the metal wire 4 is clamped between the other end of the clamp 302 and the clamping plate 304. Then, the traction mechanism 2 drives the pulling mechanism 3 to pull the metal wire 4. During the pulling process, the motor 8 is started simultaneously to drive the reel 6 to wind the metal wire 4. The winding amount of the reel 6 on the metal wire 4 is consistent with the pulling amount of the pulling mechanism 3 on the metal wire 4, so that the metal wire 4 is always in a taut state. Therefore, the traction mechanism 2 repeatedly moves the pulling mechanism 3, so that the pulling mechanism 3 repeatedly pulls the metal wire 4, thereby realizing the automatic pulling of the metal wire 4.

[0038] During the drawing process of the drawing mechanism 3, the reel 6 does not reel in the wire 4. The movable seat 301 pushes the rack 3011 to move. The moving rack 3011 drives the third gear 906 to rotate. The third gear 906 drives the four sets of pawls 908 to rotate. Since the pawls 908 abut against the corresponding teeth 907, the pawls 908 drive the second gear 905 to rotate through the teeth 907. The second gear 905 drives the transmission shaft 904 and the corresponding guide wheel 902 to rotate together. At the same time, the second gear 905 drives another set of guide wheels 902 to rotate through the first gear 903. The two sets of guide wheels 902 rotating synchronously convey the wire 4 towards the reel 6, so that the wire... 4 accumulates between the reel 6 and the take-up mechanism 9. During this process, the four sets of locking blocks 909 rotate together with the third gear 906. The locking blocks 909 squeeze the slots 11 on the chuck 910. Under the rebound force of the first spring 911, the locking blocks 909 repeatedly squeeze the chuck 910 until the pulling mechanism 3 moves back towards the eye mold 5. During the back movement, the reel 6 winds up the metal wire 4 until the metal wire 4 is straightened. At the same time, because the pawl 908 cannot abut against the corresponding tooth 907, and under the locking force of the locking blocks 909 and the slots 11, the second gear 905 cannot rotate, and the two sets of guide wheels 902 will not continue to transmit the metal wire 4.

[0039] When the metal wire 4 is pulled, the two sets of guide wheels 902 convey the metal wire 4 towards the reel 6. The metal wire 4 will disengage from the roller 45. Under the rebound force of the second spring 44, the movable arm 43 moves downward along the slide bar 42. When the reel 6 winds up the metal wire 4, the metal wire 4 comes into contact with the roller 45 again and squeezes the roller 45 to move upward. The roller 45 pushes the movable arm 43 upward along the slide bar 42 until the second spring 44 is in a semi-compressed state. At this time, if the winding amount of the reel 6 is greater than the pulling amount of the metal wire 4, the movable arm 43 will continue to move upward from the initial state, further compressing the semi-compressed second spring 44. If the winding amount of the reel 6 is less than the pulling amount of the metal wire 4, the movable arm 43 will continue to move downward from the initial state.
