Description

Technical Field

[0001] This invention relates to the field of metal wire straightening technology, specifically to a multi-station metal wire straightening machine. Background Technology

[0002] Metal wire straightening refers to the plastic deformation treatment of metal wires (such as steel wire, copper wire, aluminum wire, high-quality aluminum alloy plates, high-quality magnesium materials, copper materials, titanium materials, etc.) to eliminate shape defects such as bending and twisting generated during production, transportation, or winding, and restore them to a straight state. This process is crucial in metal processing because straightness directly affects the efficiency and accuracy of subsequent processing (such as cutting and assembly), and can improve the dimensional consistency, stability, and service life of finished products. This type of straightening usually includes flat roller straightening, rotary mandrel straightening, and tension straightening, which improves the straightness of the wire and facilitates subsequent automated processing.

[0003] Application CN204867201U discloses a wire straightener that can straighten bent wires through the V-shaped grooves of the lower and upper straightening wheels, so as to facilitate subsequent equipment to cut and crimp the wires, improve the accuracy of cutting and crimping, and increase the yield. In addition, the upper straightening wheel group can be raised and lowered by a lifting device, so that the upper and lower straightening wheel groups can be separated or joined together to facilitate wire threading, making it more convenient to use.

[0004] Application CN219357741U discloses a wire straightening device. By setting up front and rear pressure plates with adjustable front and rear distances, the device can press the wire back and forth by shortening the distance between the front and rear pressure plates, thereby straightening the portion of the wire that is bent in the front and rear directions during a single straightening process. By setting up front and rear straightening rollers with adjustable vertical distances, the device can press the wire vertically by shortening the distance between the front and rear straightening rollers, thereby straightening the portion of the wire that is bent in the vertical direction during a single straightening process.

[0005] However, the above-disclosed metal wire straightening device still has the following problems in actual use: it straightens bent metal wires by means of straightening wheel sets, but the straightening wheel sets are difficult to adapt efficiently. Metal wires of different diameters are subjected to the same pressure from the straightening wheel sets, which can easily affect the internal stress of the wire or cause wear when in contact and squeezing. At the same time, straightening in one direction is prone to misalignment with the bend due to the rotation of the wire, making it difficult to achieve all-round straightening operation.

[0006] Therefore, we propose a multi-station metal wire straightening machine to solve the problems mentioned above. Summary of the Invention

[0007] The purpose of this invention is to provide a multi-station metal wire straightening machine to solve the problems of existing straightening processes that use straightening roller sets to straighten bent metal wires. However, the straightening roller sets are difficult to adapt efficiently, and metal wires of different diameters are subjected to the same pressure from the straightening roller sets. This can easily affect the internal stress of the wire or cause wear when in contact with the rollers. At the same time, unidirectional straightening can easily cause misalignment with the bend due to the rotation of the wire, making it difficult to achieve omnidirectional straightening operations.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a multi-station metal wire straightening machine, comprising straightening platforms distributed front to back, the straightening platforms being interconnected via a connecting base at their bottom ends; and further comprising: A straightening mechanism is provided above the straightening platform, and the straightening mechanism includes a straightening wheel set, which is rotatably installed at equal intervals on the rear top surface of the straightening platform. The straightening mechanism includes a traction bracket, and the traction bracket is equipped with a traction wheel set inside through a bearing for traction of the metal wire to straighten the bent part. The metal wire includes high-quality aluminum alloy plate, high-quality magnesium material, copper material, and titanium material. The left end of the straightening platform is provided with a lubrication mechanism, which includes a lubrication ring brush and a lubrication brush group inside the lubrication ring brush, for fitting onto the outer wall of the wire to achieve contact lubrication.

[0009] Preferably, the lubrication mechanism includes a lubrication platform, which is fixedly installed above the left end of the straightening platform. A bearing base is fixedly installed on both the front and rear sides of the top of the lubrication platform. The upper end of the bearing base is rotatably connected to the inside of the right side of the lubrication ring brush through a bearing, so that the lubrication ring brush rotates under the support of the bearing base.

[0010] Preferably, the lubrication mechanism includes a drive gear rotatably mounted on the left side of the bottom end of the bearing base, and the drive gear is meshed with a transmission gear block. The transmission gear block is fixedly mounted at an equal angle inside the left side of the lubrication ring brush, and the left end shaft of the drive gear is meshed with the outer wall of the drive shaft through a bevel gear set.

[0011] Preferably, the lubrication mechanism includes a drive shaft that is rotatably mounted on the top surface of the support base via a bearing, and the outer walls of the front and rear sides of the drive shaft are provided with reciprocating thread grooves. The drive shaft is threaded to the outer end of the sealing plug rod through the reciprocating thread grooves on the front and rear sides, and the inner end of the sealing plug rod is slidably disposed inside the lubricating oil cylinder.

[0012] Preferably, the lubrication mechanism includes a lubricating oil cylinder fixedly installed on the front and rear sides of the top of the lubrication platform, and the upper end of the lubricating oil cylinder is connected to the middle of the one-way oil pipe, and the upper end of the one-way oil pipe is connected to the inside of the bearing base, so as to deliver the lubricating oil to the inside of the lubrication ring brush and coat it onto the outer wall of the metal wire.

[0013] Preferably, the lubrication mechanism includes a lubricating oil tank, which is fixedly installed on the bottom surface of the lubrication platform. The lubricating oil tank and the lubricating oil cylinder are connected by a one-way oil pipe at the lower end, which is used to draw the lubricating oil inside the lubricating oil tank into the lubricating oil cylinder and spray it onto the lubricating brush group on the inner wall of the lubrication ring brush.

[0014] Preferably, the straightening mechanism includes a sliding block, which is slidably installed at the front of the straightening platform at equal distances. The upper end of the sliding block is provided with a set of abutting wheels via a bearing, and the abutting wheels and the straightening wheels behind it are distributed in a staggered manner at equal distances in the front-to-back direction.

[0015] Preferably, the straightening mechanism includes an abutting slide bar, the rear end of which is fixedly installed at the center of the front of the abutting slider, and the front end of which slides through the front of the straightening platform. The front end of the abutting slide bar is connected to the straightening platform by a return spring.

[0016] Preferably, the straightening mechanism includes a traction bracket that is slidably installed between adjacent straightening wheel sets, and the front end of the traction bracket is fixedly connected to the rear end of the contact slider, and the traction wheel sets above the traction bracket are distributed in a one-to-one correspondence with the contact wheel sets.

[0017] Preferably, the straightening mechanism includes a transmission shaft, which is rotatably mounted in front of the top of the straightening platform via bearings. The right ends of the transmission shafts on the front and rear sides are connected to each other via pulley assemblies. Furthermore, transmission cams are fixedly mounted at equal intervals on the outer wall of the transmission shaft, and adjacent transmission cams are arranged in opposite directions. The transmission cams alternately slide by rotating against the slider to achieve straightening and shaping of the metal wire.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows: This multi-station metal wire straightening machine uses a lubrication mechanism at the left end of the straightening platform to provide rotary lubrication for the through-wire. During the straightening operation, the wire is squeezed by the sliding traction wheel set and the contact wheel set, which assists in straightening the wire from multiple directions. At the same time, it reduces the friction when in contact with the wire to avoid damage to the wire. The specific details are as follows: 1. The end of the wire passes through the lubrication ring brush and is stretched to one side of the straightening platform. It is clamped by the straightening wheel set and the contact wheel set, and the end of the metal wire is pulled and moved by the traction machine.

[0019] 2. The reciprocating threaded groove of the drive shaft drives the threaded sealing plug rod to move outward of the lubricating oil cylinder, so that the negative pressure cavity draws the lubricating oil from the lubricating oil tank into the lubricating oil cylinder through the one-way oil pipe. When the sealing plug rod moves in the opposite direction, it squeezes the lubricating oil through the one-way oil pipe to be delivered to the bearing base, and then to the lubricating brush group inside the lubricating ring brush, so as to coat and lubricate the wires that are in contact, and avoid damage due to friction during subsequent straightening.

[0020] Furthermore, the drive shaft drives the drive gear to rotate via a bevel gear assembly. The drive gear meshes with the transmission gear block to rotate the lubrication ring brush. When the lubrication brush assembly is rotated, it coats the wire in all directions, avoiding dead angles that could affect subsequent straightening operations.

[0021] 3. The moving wire above the straightening platform drives the straightening wheel set and the contact wheel set to rotate. The transmission shaft drives the transmission cam on the outer wall to rotate. After the outer end of the transmission cam presses against the contact slider, it drives the contact wheel set above to press the wire backward for straightening.

[0022] Furthermore, when the transmission cam continues to rotate, it no longer squeezes the contact slider. Instead, it moves forward after being extended and stretched by the return spring on the outer wall of the contact slider. This causes the contact slider to drive the traction bracket and the traction wheel set to slide forward synchronously. After the traction wheel set contacts the wire, it squeezes the wire, thereby assisting in straightening the bent wire from multiple directions. At the same time, it reduces the friction when in contact with the wire to avoid damaging the wire. Attached Figure Description

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] Please see Figures 1-10 The present invention provides the following technical solution: Example 1: To address the problems existing in the straightening of metal wires, this example discloses the following technical solution: a multi-station metal wire straightening machine, comprising straightening platforms 1 distributed front to back, which are interconnected by a connecting frame 2 at their bottom ends; a lubrication mechanism is provided at the left end of the straightening platform 1, which includes a lubrication ring brush 6, and a lubrication brush group 7 is provided inside the lubrication ring brush 6 for contact lubrication by fitting it onto the outer wall of the wire; the lubrication mechanism includes a lubrication platform 8, which is fixedly installed above the left end of the straightening platform 1, and a bearing base 9 is fixedly installed on both the front and rear sides of the top of the lubrication platform 8, and the upper end of the bearing base 9 is rotatably connected to the inside of the right side of the lubrication ring brush 6 through a bearing, so that the lubrication ring brush 6 rotates under the support of the bearing base 9.

[0027] The lubrication mechanism includes a drive gear 10 rotatably mounted on the left side of the bottom of the support base 9 with a bearing. The drive gear 10 is meshed with a transmission gear block 11. The transmission gear block 11 is fixedly mounted at an equal angle inside the left side of the lubrication ring brush 6. The left end shaft of the drive gear 10 is meshed with the outer wall of the drive shaft 13 through a bevel gear set 12. The drive shaft 13 included in the lubrication mechanism is rotatably mounted above the top surface of the support base 9 with a bearing. The front and rear outer walls of the drive shaft 13 are provided with reciprocating threaded grooves 14. The drive shaft 13 is threadedly connected to the outer end of the sealing plug rod 15 through the reciprocating threaded grooves 14 on the front and rear sides. The inner end of the sealing plug rod 15 is slidably disposed inside the lubricating oil cylinder 16.

[0028] The lubrication mechanism includes a lubricating oil cylinder 16 fixedly installed on the front and rear sides of the top of the lubrication platform 8, and the upper part of the inner end of the lubricating oil cylinder 16 is connected to the middle of the one-way oil pipe 17. The upper end of the one-way oil pipe 17 is connected to the inside of the support base 9, and delivers lubricating oil to the inside of the lubrication ring brush 6 to coat the outer wall of the metal wire. The lubrication mechanism includes a lubricating oil tank 18, and the lubricating oil tank 18 is fixedly installed on the bottom surface of the lubrication platform 8. The lubricating oil tank 18 and the lubricating oil cylinder 16 are connected through the lower end of the one-way oil pipe 17, which is used to draw the lubricating oil inside the lubricating oil tank 18 into the lubricating oil cylinder 16 and spray it onto the lubricating brush group 7 on the inner wall of the lubrication ring brush 6.

[0029] like Figures 1-2 , Figures 5-6 As shown, when straightening a metal wire is required, the end of the wire is first passed through the lubrication ring brush 6 above the lubrication platform 8, so that the outer wall of the wire comes into contact with the lubrication brush group 7 on the inner wall of the lubrication ring brush 6. At the same time, the end of the wire is pulled towards the straightening platform 1, so that the wire is between the straightening wheel group 3 and the contact wheel group 20. Finally, the end of the wire is connected to the traction unit, and the traction unit drives the wire to move.

[0030] Furthermore, the motor above the lubrication platform 8 drives the drive shaft 13 to rotate, causing the drive shaft 13 to drive the threaded sealing rod 15 to slide synchronously towards the outer wall through the reciprocating threaded groove 14 on the outer wall. The inner end of the sealing rod 15 moves towards the opening of the lubricating oil cylinder 16, thereby creating a negative pressure state inside the lubricating oil cylinder 16. The lubricating oil cylinder 16 under negative pressure then draws the lubricating oil from the lubricating oil tank 18 through the through-connected one-way oil pipe 17, allowing the lubricating oil to be stored inside the lubricating oil cylinder 16. After the drive shaft 13 drives the sealing rod 15 to move in the opposite direction, the lubricating oil inside the lubricating oil cylinder 16 is squeezed and transported to the interior of the bearing base 9 through the upper end of the one-way oil pipe 17. The lubricating oil is also transported to the inner end of the lubricating brush group 7 through the through-connected lubricating ring brush 6, so that it can be coated on the outer wall of the wire, thereby reducing the friction of the wire during subsequent straightening operations and preventing damage.

[0031] like Figures 3-4 As shown, during the rotation of the drive shaft 13 above the lubrication platform 8, the drive gear 10 is driven to rotate by the bevel gear group 12 at its outer end. The drive gear 10 meshes with the transmission gear block 11 to drive the lubrication ring brush 6 to rotate. The lubrication ring brush 6 drives the lubrication brush group 7 at its inner end to rotate around the internal metal wire so as to coat the lubricating oil to the outer wall of the metal wire in all directions, avoiding the existence of lubrication dead corners that would affect the subsequent straightening operation of the metal wire.

[0032] Example 2: To address the existing problems in straightening metal wires, this example discloses the following technical solution: A straightening mechanism is provided above the straightening platform 1, and the straightening mechanism includes a straightening wheel set 3, which is rotatably mounted at equal intervals on the rear top surface of the straightening platform 1; the straightening mechanism includes a traction bracket 4, and a traction wheel set 5 is rotatably mounted inside the traction bracket 4 via bearings, used to straighten the bent parts of the metal wire, and the metal wire includes high-quality aluminum alloy plate, high-quality magnesium material, copper material, and titanium material; the straightening mechanism includes an abutment slider 19, which is slidably mounted at equal intervals in the front of the straightening platform 1, and an abutment wheel set 20 is rotatably mounted at the upper end of the abutment slider 19 via bearings, and the abutment wheel set 20 and the rear straightening wheel set 3 are distributed in a staggered manner at equal intervals in the front-to-back direction.

[0033] The straightening mechanism includes an abutting slide bar 21, the rear end of which is fixedly installed at the center of the front of the abutting slider 19, and the front end of which slides through the front of the straightening platform 1. The front end of the abutting slide bar 21 is connected to the straightening platform 1 by a return spring 25. The straightening mechanism includes a traction bracket 4 which is slidably installed between adjacent straightening wheel sets 3. The front end of the traction bracket 4 is fixedly connected to the rear end of the abutting slider 19, and the traction wheel sets 5 above the traction bracket 4 are distributed one-to-one with the abutting wheel sets 20.

[0034] The straightening mechanism includes a transmission shaft 22, which is rotatably mounted in front of the top of the straightening platform 1 via bearings. The right ends of the transmission shafts 22 on the front and rear sides are connected to each other via a pulley assembly 23. Transmission cams 24 are fixedly mounted at equal intervals on the outer wall of the transmission shaft 22. Adjacent transmission cams 24 are arranged in opposite directions. The transmission cams 24 alternately slide by rotating and abutting against the slider 19 to achieve straightening and shaping of the metal wire.

[0035] like Figures 7-8 As shown, during the process of the metal wire being pulled and moved above the straightening platform 1, it is limited by the straightening wheel group 3 and the contact wheel group 20 which are distributed in a staggered manner. When they come into contact, the straightening wheel group 3 and the contact wheel group 20 are rotated respectively. At the same time, the motor installed on the right side of the straightening platform 1 drives the transmission shaft 22 connected to the pulley assembly 23 to rotate. The transmission shaft 22 drives the transmission cams 24, which are fixedly installed at equal intervals on the outer wall, to rotate in different directions.

[0036] Furthermore, after the upper end of the transmission cam 24 rotates to the outer wall of the contact slider 19, it squeezes the contact slider 19 to slide backward toward the straightening platform 1, and drives the contact wheel group 20 connected to its upper end to approach the outer wall of the wire, thereby squeezing the wire backward, and the straightening wheel group 3 at the rear makes an opposite contact; furthermore, after the upper end of the transmission cam 24 rotates away from the contact slider 19, the return spring 25 sleeved on the outer wall of the contact slide rod 21 at its front end extends, thereby driving the contact slider 19 and the traction bracket 4 to slide forward synchronously, so as to drive the internal traction wheel group 5 to move forward to squeeze the wire, thereby assisting the straightening of the bent wire from multiple directions, while reducing the friction when in contact with the wire to avoid damage to the wire.

[0037] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
