TECHNICAL FIELD

[0001] The present application relates to the technical field of metal wire straightening, in particular to a multi-station metal wire straightening machine. BACKGROUND

[0002] Metal wire straightening refers to a process of plastic deformation of metal wires (such as steel wire, copper wire, aluminum wire, high-quality aluminum alloy plate, high-quality magnesium material, copper material, titanium material manufacturing, etc.) to eliminate the shape defects such as bending and twisting generated during production, transportation or winding, and to restore the straight state, which 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 size consistency, stability and service life of the finished product. This type of straightening usually includes flat roller straightening, rotating mandrel straightening and stretching straightening, etc., which improves the straightness of the wire for subsequent automated processing.

[0003] The application with publication number CN204867201U discloses a wire straightener, which can straighten the bent wire through the V-shaped groove of the lower straightening wheel and the upper straightening wheel, so as to improve the accuracy of cutting, terminal pressing and other work, improve the yield, and the upper straightening wheel set can be lifted and lowered by the lifting device, so that the upper straightening wheel set and the lower straightening wheel set can be relatively separated or folded, to facilitate the threading of the wire, and the use is more convenient.

[0004] The application with publication number CN219357741U discloses a wire straightening device, which can hold the wire in front and back by shortening the distance between the front and rear pressure plates, and then straighten the part bent in the front and back direction during single straightening process; and can hold the wire in up and down by shortening the distance between the front and rear straightening wheels, and then straighten the part bent in the up and down direction during single straightening process.

[0005] However, the above-mentioned metal wire straightening device has the following problems in actual use: the straightening wheel set is used to straighten the metal wire with bending, but the straightening wheel set is difficult to adapt efficiently, the pressure of the straightening wheel set on metal wires of different diameters is the same, which may affect the internal stress of the wire or cause wear during contact and extrusion, and the straightening in a single direction may be misaligned with the bending part due to the rotation of the wire, making it difficult to achieve omnidirectional straightening operation.

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

[0026] Please refer to Figures 1-10 The present application provides the following technical solutions: Embodiment 1: In order to solve the problems existing in the straightening of the existing metal wire, the following technical solutions are disclosed in this embodiment: a multi-station metal wire straightening machine, comprising straightening platforms 1 distributed front and back, and the straightening platforms 1 are connected to each other through the connecting chassis 2 at the bottom end; the left end of the straightening platform 1 is provided with a lubricating mechanism, and the lubricating mechanism comprises a lubricating ring brush 6, and the inside of the lubricating ring brush 6 is provided with a lubricating brush set 7, which is used for sleeving on the outer wall of the wire to realize contact lubrication; the lubricating mechanism comprises a lubricating platform 8, and the lubricating platform 8 is fixedly installed above the left end of the straightening platform 1, and the top surface of the lubricating platform 8 is fixedly installed with bearing bases 9 on the front and back sides, and the upper end of the bearing base 9 is rotatably connected to the right side inside of the lubricating ring brush 6 through a bearing, so that the lubricating ring brush 6 rotates under the bearing of the bearing base 9.

[0027] The lubricating mechanism comprises a driving gear 10 rotatably mounted on the left side of the bottom end of the bearing base 9, and the driving gear 10 is in meshing connection with the transmission tooth block 11, and the transmission tooth block 11 is fixedly installed at the left side of the inner wall of the lubricating ring brush 6, and the left end rotating shaft of the driving gear 10 is in meshing connection with the outer wall of the driving rotating shaft 13 through the bevel gear set 12; the driving rotating shaft 13 is rotatably mounted on the top surface of the bearing base 9, and the front and rear outer walls of the driving rotating shaft 13 are provided with reciprocating screw grooves 14, and the driving rotating shaft 13 is in threaded connection with the outer end of the sealing plug rod 15 through the reciprocating screw grooves 14 on the front and rear sides, and the inner end of the sealing plug rod 15 is slidably arranged in the inner wall of the lubricating oil cylinder 16.

[0028] The lubricating mechanism comprises a lubricating oil cylinder 16 fixedly installed on the top surface of the lubricating platform 8, and the inner end of the lubricating oil cylinder 16 is in through connection with the middle part of the one-way oil pipe 17, and the upper end of the one-way oil pipe 17 is in through connection with the inner wall of the bearing base 9, and the lubricating oil is delivered to the inner wall of the lubricating ring brush 6; the lubricating mechanism comprises a lubricating oil tank 18, and the lubricating oil tank 18 is fixedly installed on the bottom surface of the lubricating platform 8, and the lubricating oil tank 18 is in through connection with the lubricating oil cylinder 16 through the lower end of the one-way oil pipe 17, for pumping the lubricating oil in the lubricating oil tank 18 into the lubricating oil cylinder 16, and spraying the lubricating brush group 7 on the inner wall of the lubricating ring brush 6.

[0029] As shown in Figures 1-2 , Figures 5-6 When it is necessary to straighten the metal wire, first pass the end of the wire through the lubricating ring brush 6 above the lubricating platform 8, so that the outer wall of the wire is in contact with the lubricating brush group 7 on the inner wall of the lubricating ring brush 6, and at the same time, the end of the wire is continuously pulled towards the straightening platform 1, so that the wire is between the straightening wheel set 3 and the abutting wheel set 20, and finally the end of the wire is connected to the traction machine set, and the wire is moved by the traction machine set.

[0030] Further, the motor drives the driving shaft 13 above the lubrication platform 8 to rotate, so that the driving shaft 13 drives the threaded connection sealing plug rod 15 to slide outward through the reciprocating threaded groove 14 opened in the outer wall, and the inner end of the sealing plug rod 15 moves to the open end of the lubricating oil cylinder 16, thereby driving the internal cavity of the lubricating oil cylinder 16 to be in a negative pressure state.

[0031] As shown in Figures 3-4 the driving shaft 13 above the lubrication platform 8 drives the driving gear 10 engaged and connected to rotate during rotation, and the lubricating ring brush 6 is driven to rotate by the driving gear 10 engaging the transmission tooth block 11, and the lubricating brush group 7 at the inner end of the lubricating ring brush 6 rotates around the metal wire inside, so as to coat the lubricating oil on the outer wall of the metal wire in all directions, avoiding the existence of lubrication dead angle affecting the subsequent straightening operation of the metal wire.

[0032] Embodiment 2: In order to solve the existing problem of metal wire during straightening, the following technical scheme is disclosed in this embodiment. The straightening platform 1 is provided with a straightening mechanism, and the straightening mechanism comprises a straightening wheel group 3, and the straightening wheel group 3 is installed at equal distances on the top surface of the rear of the straightening platform 1. The straightening mechanism comprises a traction bracket 4, and the traction bracket 4 is provided with a traction wheel group 5 inside through a bearing. The traction bracket 4 is used to straighten the curved part of the metal wire, and the metal wire comprises high-quality aluminum alloy plate, high-quality magnesium material, copper material and titanium material. The straightening mechanism comprises a contact sliding block 19, and the contact sliding block 19 is slidably installed at equal distances on the front inside of the straightening platform 1. The upper end of the contact sliding block 19 is provided with a contact wheel group 20 through a bearing, and the contact wheel group 20 and the rear straightening wheel group 3 are distributed and arranged in a front and rear direction at equal distances.

[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.

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.
