Description

Technical Field

[0001] The present invention belongs to the field of rolling processing of other non-ferrous metals, and specifically relates to a rolling processing device for metal wire. Background Art

[0002] The drawing of metal wire is an important metal processing technology, belonging to the category of rolling processing of non-ferrous metals. By drawing metal wire, the microstructure and mechanical properties of the metal wire can be improved, so that high-strength metal wire with more excellent performance can be manufactured. At present, metal wire drawing is generally processed by a rolling processing device, with high quality and fast efficiency.

[0003] The patent with publication number 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 arranged inside the clamp, and the external electromagnetic coil is sleeved on the linear guide rail. An inner winding piston is slidably sleeved on the linear guide rail, an inner electromagnetic coil is arranged inside the inner winding piston, and a jaw for clamping the metal wire is fixedly installed on the inner winding piston. A solenoid valve is arranged on the jaw, and a die is arranged directly in front of the jaw. This solution realizes the opening and closing of the jaw through the solenoid valve, so that the metal wire can be fixed on the jaw, and then drives the jaw to reciprocate through the traction structure to realize the drawing of the metal wire after passing through the die, so as to obtain high-strength metal wire. Since the traction structure is driven electromagnetically, sliding friction is avoided, and the appearance surface quality of the metal wire is improved.

[0004] In the above solution, the jaw is driven by the traction structure to draw the metal wire. During this process, when changing the position of the jaw clamping the metal wire, it is necessary for the staff to hold the metal wire to realize the clamping of the metal wire by the jaw, which is troublesome and time-consuming to operate, and reduces the drawing efficiency of the metal wire. Therefore, the present invention provides a rolling processing device for metal wire. Summary of the Invention

[0005] In order to make up for the deficiencies of the prior art and solve at least one technical problem proposed in the background art.

[0006] The technical solution adopted by the present invention to solve its technical problems is as follows: A rolling processing device for metal wire according to the present invention includes a base, a traction mechanism is arranged on the base, a drawing mechanism for drawing metal wire is arranged on the traction mechanism, a die is arranged in front of the drawing mechanism, and a coiling reel is arranged behind the drawing mechanism. The coiling reel is rotatably installed on a bracket, and a motor for driving the coiling reel is fixedly installed on the bracket. The drawing mechanism includes a movable seat, the movable seat is fixedly installed on the traction mechanism, a clamp is hinged on the movable seat, the upper end of a cylinder is hinged to one end of the clamp, the lower end of the cylinder is hinged to the movable seat, and a clamping piece is arranged below the other end of the clamp. The clamping piece is fixedly installed on the movable seat. Through the cooperation of the coiling disc and the drawing mechanism, the wire is kept in a straight state during the drawing process, ensuring that the drawing mechanism can accurately grip the wire when changing the clamping position, which not only improves the automation efficiency of the device, but also improves the drawing processing efficiency of the wire.

[0007] Preferably, the drawing mechanism further includes a slider, the slider is fixedly installed on the bottom surface of the movable seat, the slider is slidably connected to the slide rail, the slide rail is fixedly installed on the support frame, and the support frame is fixedly installed on the base; Specifically, during the process of the above-mentioned traction mechanism driving the drawing mechanism to draw the wire, the movable seat will drive the slider to slide along the slide rail, and the cooperation between the slider and the slide rail plays a guiding role in the movement of the drawing mechanism.

[0008] Preferably, a wire take-up mechanism is arranged between the drawing mechanism and the coiling disc. The wire take-up mechanism includes a fixed frame, the fixed frame is fixedly installed on the base, two groups of guide wheels rotatably installed on the fixed frame, the wire passes through between the two groups of guide wheels, a first gear is installed at the end of one group of guide wheels, a transmission shaft is connected to the end of the other group of guide wheels, a second gear fixedly sleeved on the transmission shaft, the second gear meshes with the first gear, a third gear is rotatably installed on the transmission shaft, a plurality of groups of teeth are arranged in a surrounding manner on one side inside the second gear, one end of the pawl is clamped to the teeth, the other ends of the four 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 blocks are arranged on the other end face of the third gear, the four blocks all mesh with the chuck, two guide columns are connected to one side of the chuck, the guide columns are inserted into the support, the chuck is movably sleeved on the transmission shaft, one end of the transmission shaft is rotatably connected to the support, the lower end of the support is fixedly connected to the fixed frame, a first spring is arranged between the support and the third gear, four card slots are arranged at equal angles on the chuck, and the four blocks respectively engage the four card slots; Under the action of the rebounding force of the first spring, the block repeatedly presses the chuck until the drawing mechanism moves back towards the eye die mold. During the backward movement, the coiling disc winds up the wire until the wire is straightened. At the same time, since the pawl cannot resist the corresponding teeth and under the clamping force of the block and the card slot, the second gear cannot rotate, and the two guide wheels will not continue to convey the wire. Since the wire take-up mechanism can convey the wire synchronously with the feed amount of the traction mechanism during the wire drawing process, it avoids the wire being drawn too tight or too loose, and improves the wire drawing efficiency.

[0009] Preferably, the wire take-up mechanism further includes a buffer mechanism. The buffer mechanism includes a fixed plate, the fixed plate is fixedly installed on the fixed frame, two groups of slide bars fixedly installed on the fixed plate, a movable arm slidably connected to the two groups of slide bars, a roller rotatably installed at the end of the movable arm, a second spring is arranged between the movable arm and the fixed plate, and the roller is in rolling connection with the wire; The roller pushes the movable arm to move upward along the slide rod until the second spring is in a semi-compressed state. At this time, if the reel winding amount is greater than the wire pulling amount, the movable arm will continue to move upward on the basis of the initial state, so that the second spring in the semi-compressed state will be further compressed; if the reel winding amount is less than the wire pulling amount, the movable arm will continue to move downward on the basis of the initial state. Therefore, under the action of the rebound force of the second spring, the wire is kept straight while ensuring that the wire is not broken, giving a certain correction space for the reel winding amount error to ensure that the wire pulling can proceed normally.

[0010] The beneficial effects of the present invention are as follows: 1. Through the cooperation between the reel and the pulling mechanism, the metal wire is always in a straight state during the pulling process, ensuring that the pulling mechanism can accurately clamp the metal wire when changing the clamping position, which not only improves the automation efficiency of the device, but also improves the efficiency of the metal wire drawing process.

[0011] 2. During the process of the drawing mechanism drawing the metal wire, the reel does not reel in the metal wire, the movable seat pushes the rack to move, the moving rack drives the third gear to rotate, the third gear drives the four groups of ratchets to rotate, because the ratchets are against the corresponding teeth, the ratchets rotate the second gear through the teeth, the second gear drives the transmission shaft together with the corresponding guide wheel to rotate, and at the same time, the second gear drives another group of guide wheels to rotate through the first gear. The two groups of guide wheels rotating synchronously transmit the metal wire toward the reel, so that the metal wire accumulates between the reel and the take-up mechanism. In this process, the four groups of clamps rotate with the third gear, and the clamps squeeze The card slot on the pressing chuck is repeatedly squeezed by the card block under the rebound force of the first spring until the drawing mechanism moves back toward the eye mold. During the backward movement, the reel reels the metal wire until the metal wire is straightened. At the same time, the pawl cannot resist the corresponding teeth and the second gear cannot rotate under the card force of the card block and the card slot. The two sets of guide wheels will not continue to transmit the metal wire. During the process of drawing the metal wire, the wire-receiving mechanism can transmit the metal wire synchronously with the feed amount of the traction mechanism, thereby preventing the metal wire from being pulled too tight or too loose, thereby improving the drawing efficiency of the metal wire.

[0012] 3. When drawing a wire, two sets of guide wheels convey the wire towards the reel. The wire will separate from the roller contact. Under the rebounding force of the second spring, the movable arm moves downward along the slide bar. When the reel winds up the wire, the wire comes into contact with the roller again and squeezes the roller to move upward, causing the roller to push the movable arm to move upward along the slide bar until the second spring is in a semi-compressed state. At this time, if the winding amount of the reel is greater than the drawing amount of the wire, the movable arm will continue to move upward based on the initial state, further compressing the semi-compressed second spring. If the winding amount of the reel is less than the drawing amount of the wire, the movable arm will continue to move downward based on the initial state. Therefore, under the rebounding force of the second spring, while ensuring that the wire is not broken, the wire is kept straight, giving a certain correction space for the winding amount error of the reel and ensuring the normal progress of wire drawing.

Detailed implementation manners

[0023] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0024] Example 1: As Figure 1 With Figure 2 shown, a wire rolling and processing device according to an embodiment of the present invention includes a base 1, a traction mechanism 2 is arranged on the base 1, a drawing mechanism 3 for drawing a wire 4 is arranged on the traction mechanism 2, an eye die mold 5 is arranged in front of the drawing mechanism 3, a reel 6 is arranged behind the drawing mechanism 3, the reel 6 is rotatably installed on a bracket 7, and a motor 8 for driving the reel 6 is fixedly installed on the bracket 7. The drawing mechanism 3 includes a movable seat 301, the movable seat 301 is fixedly installed on the traction mechanism 2, a clamp 302 hinged on the movable seat 301, the upper end of a cylinder 303 is hinged to one end of the clamp 302, the lower end of the cylinder 303 is hinged to the movable seat 301, and a clamping piece 304 is arranged below the other end of the clamp 302, and the clamping piece 304 is fixedly installed on the movable seat 301.

[0025] Specifically, the traction mechanism 2 adopts the corresponding structure in the high-strength tungsten alloy ultra-fine wire drawing device with the above-mentioned publication number CN115446136B. In the initial state, the drawing mechanism 3 is close to the eye die 5, and the fixture 302 is in the open state. When wire drawing processing is required for the metal wire 4, the metal wire 4 is passed through the eye die 5, and then the end of the metal wire 4 is clamped by pliers for drawing, and the metal wire 4 is passed through between the other end of the fixture 302 and the clamping piece 304 until the metal wire 4 is wound around the reel 6. Then, the cylinder 303 is started, and the cylinder 303 pushes the fixture 302 upward, so that the metal wire 4 is clamped between the other end of the fixture 302 and the clamping piece 304. Then, the drawing mechanism 3 is driven by the traction mechanism 2 to draw the metal wire 4. During the drawing process, the motor 8 is synchronously started to drive the reel 6 to wind up the metal wire 4. The winding amount of the reel 6 for the metal wire 4 is kept consistent with the drawing amount of the drawing mechanism 3 for the metal wire 4, so that the metal wire 4 is always in a straightened state. Therefore, the drawing mechanism 3 is repeatedly carried by the traction mechanism 2, and the drawing mechanism 3 repeatedly draws the metal wire 4, thereby realizing the automatic drawing of the metal wire 4. Compared with the prior art, through the cooperation of the reel 6 and the drawing mechanism 3, the metal wire 4 is always in a straightened state during the drawing process, ensuring 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 processing efficiency of the metal wire 4.

[0026] Further, the drawing mechanism 3 further includes a slider 305. The slider 305 is fixedly installed on the bottom surface of the movable seat 301. The slider 305 is slidably connected to the slide rail 306. The slide rail 306 is fixedly installed on the support frame 307. The support frame 307 is fixedly installed on the base 1.

[0027] Specifically, during the process of the above-mentioned traction mechanism 2 driving the drawing mechanism 3 to draw 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 drawing mechanism 3.

[0028] Such as Figures 3 to 6As shown, a wire winding mechanism 9 is provided between the drawing mechanism 3 and the reel 6. The wire winding mechanism 9 includes a fixed frame 901, which is fixedly installed on the base 1. Two sets of guide wheels 902 are rotatably installed on the fixed frame 901. The wire 4 passes between the two sets of guide wheels 902. A first gear 903 is installed at the end of one set of guide wheels 902, and a transmission shaft 904 is connected to the end of the other set of guide wheels 902. A second gear 905 is fixedly sleeved on the transmission shaft 904. The second gear 905 meshes with the first gear 903. A third gear 906 is rotatably installed on the transmission shaft 904. A number of groups of teeth 907 are arranged around the inner side of one side of the second gear 905. One end of the pawl 908 is clamped to the teeth 907. The other ends of the four pawls 908 are all hinged to one end face of the third gear 906. One end of the movable seat 301 is fixedly connected to a rack 3011. The rack 3011 meshes with the third gear 906. Four blocks 909 are arranged on the other end face of the third gear 906. The four blocks 909 all mesh with a chuck 910. Two guide columns 912 are connected to one side of the chuck 910. The guide columns 912 are inserted into a support 913. The chuck 910 is movably sleeved 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 fixed frame 901. A first spring 911 is arranged between the support 913 and the third gear 906. Four slots 11 are arranged at equal angles on the chuck 910. The four blocks 909 are respectively engaged with the four slots 11.

[0029] Specifically, the pawl 908 is made of magnet material, and the pawl 908 has an adsorption force on the tooth 907 and the second gear 905. During the process of the drawing mechanism 3 drawing the wire 4, it is necessary to accurately control the winding amount of the wire 4 by the reel 6 to ensure that the wire 4 is not too tight or too loose. However, in actual operation, there is a certain error between the feeding amount of the traction mechanism 2 and the rotation amount of the reel 6. This is likely to cause the wire 4 to be broken or the wire 4 to be too loose, affecting the drawing efficiency of the wire 4. Therefore, during the process of the drawing mechanism 3 drawing the wire 4, the reel 6 does not wind 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 pawls 908 to rotate. Since the pawl 908 abuts against the corresponding tooth 907, the pawl 908 causes the second gear 905 to rotate through the tooth 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 guide wheel 902 to rotate through the first gear 903. The two synchronously rotating guide wheels 902 convey the wire 4 towards the reel 6, causing the wire 4 to accumulate between the reel 6 and the wire take-up mechanism 9. During this process, the four blocks 909 rotate together with the third gear 906, and the block 909 squeezes the slot 11 on the chuck 910. Under the rebounding force of the first spring 911, the block 909 repeatedly squeezes the chuck 910 until the drawing mechanism 3 moves back towards the eye die 5. During the backward movement, the reel 6 winds the wire 4 until the wire 4 is straightened. At the same time, since the pawl 908 cannot abut against the corresponding tooth 907, and under the clamping force between the block 909 and the slot 11, the second gear 905 cannot rotate, and the two guide wheels 902 will not convey the wire 4 any further. Since the wire take-up mechanism 9 can convey the wire 4 synchronously with the feeding amount of the traction mechanism 2 during the process of drawing the wire 4, it avoids the wire 4 being drawn too tight or too loose and improves the drawing efficiency of the wire 4.

[0030] Embodiment 2: As Figure 7 compared with Figure 8 shown, compared with Embodiment 1, another implementation manner of the present invention is that the wire take-up mechanism 9 further includes a buffer mechanism 914. The buffer mechanism 914 includes a fixing plate 41, the fixing plate 41 is fixedly installed on the fixing frame 901, two sliding rods 42 fixedly installed on the fixing plate 41, a movable arm 43 slidably connected to the two sliding rods 42, a roller 45 rotatably installed at the end of the movable arm 43, a second spring 44 is arranged between the movable arm 43 and the fixing plate 41, and the roller 45 is in rolling connection with the wire 4.

[0031] Specifically, the distance that the above-mentioned pulling mechanism 3 pulls the metal wire 4 each time is certain. Therefore, as long as the number of revolutions of the reel 6 each time is controlled, it can be ensured that the winding amount of the reel 6 is consistent with the pulling amount of the metal wire 4. However, in the actual operation process, there will be an error in the winding amount of the reel 6. If the winding amount is greater than the pulling amount of the metal wire 4, the metal wire 4 will be pulled too tight, causing the metal wire 4 to break. If the winding amount is less than the pulling amount of the metal wire 4, the metal wire 4 will relax. When the metal wire 4 is in a straight state, the roller 45 is close to the metal wire 4, and the second spring 44 is in a semi-compressed state. When the metal wire 4 is pulled, the two sets of guide wheels 902 transmit the metal wire 4 toward the reel 6, and the metal wire 4 will be out of contact with the roller 45. Under the action of the rebound force of the second spring 44, the movable arm 43 moves along the slide rod 4 2 moves downward. When the reel 6 reels the metal wire 4, the metal wire 4 contacts the roller 45 again and squeezes the roller 45 to move upward, so that the roller 45 pushes the movable arm 43 to move upward along the slide bar 42 until the second spring 44 is in a semi-compressed state. At this time, if the reel 6 reels more than the wire 4 pulling amount, the movable arm 43 will continue to move upward on the basis of the initial state, so that the second spring 44 in the semi-compressed state is further compressed. If the reel 6 reels less than the wire 4 pulling amount, the movable arm 43 will continue to move downward on the basis of the initial state. Therefore, under the action of the rebound force of the second spring 44, the wire 4 is kept straight without breaking, giving the reel 6 a certain correction space for the reel 6 reel amount error, so as to ensure that the wire 4 pulling can proceed normally.

[0032] 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 to be pulled, and the metal wire 4 is passed between the other end of the clamp 302 and the clamping piece 304, until the metal wire 4 is wound on the reel 6, and 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 piece 304, and then the pulling mechanism 2 drives the pulling mechanism 3 to pull the metal wire 4. During the pulling process, the motor 8 is started synchronously to drive the reel 6 to reel the metal wire 4. The reel 6 keeps the reeling amount of the metal wire 4 consistent with the pulling amount of the metal wire 4 by the pulling mechanism 3, so that the metal wire 4 is always in a straight state. Therefore, the pulling mechanism 2 repeatedly transports the pulling mechanism 3, so that the pulling mechanism 3 repeatedly pulls the metal wire 4, thereby realizing automatic pulling of the metal wire 4; During the wire drawing process of the wire drawing mechanism 3 on the wire 4, the coiling reel 6 does not wind 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 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 and the corresponding guide wheels 902 to rotate together. At the same time, the second gear 905 drives another group of guide wheels 902 to rotate through the first gear 903. The two synchronously rotating guide wheels 902 convey the wire 4 towards the coiling reel 6, causing the wire 4 to accumulate between the coiling reel 6 and the wire take-up mechanism 9. During this process, the four blocks 909 rotate together with the third gear 906. The blocks 909 squeeze the slots 11 on the chuck 910. Under the rebounding force of the first spring 911, the blocks 909 repeatedly squeeze the chuck 910 until the wire drawing mechanism 3 moves back towards the eye die 5. During the backward movement, the coiling reel 6 winds the wire 4 until the wire 4 is straightened. At the same time, since the pawls 908 cannot abut against the corresponding teeth 907, and under the clamping force between the blocks 909 and the slots 11, the second gear 905 cannot rotate, and the two guide wheels 902 will not convey the wire 4 any further; When drawing the wire 4, the two guide wheels 902 convey the wire 4 towards the coiling reel 6, and the wire 4 will separate from the contact with the roller 45. Under the rebounding force of the second spring 44, the movable arm 43 moves downward along the slide bar 42. When the coiling reel 6 winds the wire 4, the wire 4 comes into contact with the roller 45 again and squeezes the roller 45 to move upward, causing the roller 45 to push the movable arm 43 to move 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 coiling reel 6 is greater than the drawing amount of the wire 4, the movable arm 43 will continue to move upward based on the initial state, further compressing the semi-compressed second spring 44. If the winding amount of the coiling reel 6 is less than the drawing amount of the wire 4, the movable arm 43 will continue to move downward based on the initial state.
