Description

Technical Field

[0001] The utility model belongs to the technical field of spring steel wire production, and in particular relates to a continuous rolling integrated equipment for multi-process production of spring steel wire with special-shaped cross-section. Background Art

[0002] The production process of spring steel wire mainly includes raw material selection, smelting, continuous casting, rolling, drawing, annealing and surface treatment. Rolling is a metal processing process, specifically a pressure processing method in which the metal billet passes through the gap between a pair of rotating rollers, and the material cross-section is reduced and the length is increased due to the compression of the rollers.

[0003] A spring steel wire flattening machine is disclosed in Chinese patent CN214211735U, which relates to the technical field of spring processing equipment. The spring steel wire flattening machine comprises a base, and hydraulic lifting cylinders are fixedly installed at the four corners of the upper surface of the base, and the top of the hydraulic lifting cylinders is commonly connected to a clamping seat, and two lower mounting seats are symmetrically and slidably installed on the center of the upper surface of the base, and the top surface of the lower mounting seat is connected to the upper mounting seat through a telescopic rod, and mounting grooves are provided at the corresponding positions of the bottom surface of the upper mounting seat and the top surface of the lower mounting seat, and a mounting shaft is clamped in the two mounting grooves, and an extrusion roller is rotatably installed on the side wall of the mounting shaft, and the two upper mounting seats are commonly threaded with a bidirectional screw rod, and the bidirectional screw rod is rotatably installed on the clamping seat, and the center of the bidirectional screw rod is connected to an adjusting motor through a worm gear mechanism, and the adjusting motor is fixedly installed on the clamping seat.

[0004] Most of the current spring steel wire flattening machines have poor applicability and do not meet the requirements of diversified production. In the above-mentioned documents, the distance between the two extrusion rollers is adjusted by driving the adjusting motor to drive the bidirectional lead screw to rotate, so as to achieve the flattening of steel wires of different diameters and the production of flat wires of different sizes. However, when rolling spring steel wires of different cross-sectional shapes, the extrusion rollers need to be removed and replaced, which is more troublesome to use and has low work efficiency.

[0005] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content

[0010] Further, the first rolling component includes a second motor. The second motor is fixedly connected to the bottom of the first sliding frame.

The cross-sectional shape of the second rolling wheel is different from that of the first rolling wheel.

[0012] Further, the guiding component includes a support column. A fourth motor is fixedly connected to the top of the support column. A third belt pulley is fixed on the output shaft of the fourth motor. A second belt is arranged on the outer surface of the third belt pulley.

[0015] The utility model has the following beneficial effects:

[0016] 1. Through the connection of the displacement component, the first rolling component and the second rolling component, the moving directions of the first rolling component and the second rolling component are opposite. When the displacement component drives the first rolling components to approach each other, the second rolling components move away from each other, so as to avoid the steel wire. When it is necessary to roll spring steel wires with different cross-sectional shapes, the displacement component drives the first rolling component and the second rolling component to move in the opposite direction. At this time, the first rolling components move away from each other to avoid the steel wire, and the second rolling components move closer to perform rolling. There is no need to disassemble and replace, which is relatively convenient to use and is beneficial to improving work efficiency.

[0017] 2. Through the connection of the first sliding frame and the first rolling wheel, and the second sliding frame and the second rolling wheel, the first screw rod and the second screw rod connected to the first sliding frame and the second sliding frame have opposite helix directions. Furthermore, the moving directions of the first sliding frame and the second sliding frame are opposite. When the first sliding frame drives the first rolling wheels to approach each other, the second sliding frame drives the second rolling wheels to move away from each other. At this time, the first rolling wheels can roll the steel wire, and vice versa. Moreover, the shapes of the first rolling wheel and the second rolling wheel are different, and steel wires with different cross-sectional shapes can be rolled. Only by changing the forward and reverse rotation of the first motor can different rolling wheels be switched. There is no need to disassemble and replace the first rolling wheel and the second rolling wheel, which is relatively convenient to use and is beneficial to improving work efficiency.

[0018] Of course, it is not necessary for any product implementing the utility model to achieve all the above advantages simultaneously. Description of the Drawings

[0028] Next, the technical solutions in the embodiments of the utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the utility model. Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the utility model.

[0029] In the description of the present utility model, it should be understood that terms such as "opening", "upper", "lower", "top", "middle", "inner", etc. indicating orientation or positional relationship are only for the convenience of describing the utility model and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the utility model.

[0030] Please refer to Figures 1 - 6 As shown, the present utility model is a continuous rolling integrated device for multi - process production of spring steel wires with special - shaped cross - sections, including a first bracket 1. A displacement assembly 2 is arranged on the outer surface of the first bracket 1. A first rolling assembly 3 and a second rolling assembly 4 are respectively arranged on the outer surface of the displacement assembly 2. A guiding assembly 5 is arranged on the side of the second rolling assembly 4. A limiting assembly 6 is arranged inside the guiding assembly 5. A cutting assembly 7 is arranged on the side of the guiding assembly 5. The moving directions of the first rolling assembly 3 and the second rolling assembly 4 are opposite. The guiding assembly 5 and the limiting assembly 6 are used to make the steel wire into a spiral shape.

[0031] Start the displacement assembly 2 to drive the first rolling assembly 3 and the second rolling assembly 4 to move along the first bracket 1. When the first rolling assemblies 3 approach each other, the second rolling assemblies 4 move away from each other. At this time, the steel wire can be passed through the first rolling assembly 3. The cross - sectional shape of the steel wire will change after being rolled by the first rolling assembly 3. The rolled steel wire enters the guiding assembly 5. The steel wire is wound into a spiral shape along the guiding assembly 5. The limiting assembly 6 inside the guiding assembly 5 can support the steel wire during shaping. After the steel wire is wound into a spring, the limiting assembly 6 is removed from the guiding assembly 5. Start the cutting assembly 7 to cut off the spring outside the guiding assembly 5. When springs with different cross - sectional shapes need to be rolled, start the displacement assembly 2 to make the first rolling assemblies 3 move away from each other. At this time, the second rolling assemblies 4 approach each other, and then rotate the guiding assembly 5 to make its cross - sectional shape match the cross - sectional shape of the steel wire rolled by the second rolling assembly 4 to produce the spring.

[0032] Through the connection of the displacement assembly 2, the first rolling assembly 3 and the second rolling assembly 4, and the opposite moving directions of the first rolling assembly 3 and the second rolling assembly 4, when the displacement assembly 2 drives the first rolling assemblies 3 to approach each other, the second rolling assemblies 4 move away from each other, so as to avoid the steel wire. When spring steel wires with different cross - sectional shapes need to be rolled, the displacement assembly 2 drives the first rolling assembly 3 and the second rolling assembly 4 to move in the opposite direction. At this time, the first rolling assemblies 3 move away from each other to avoid the steel wire, and the second rolling assemblies 4 approach each other for rolling. There is no need to disassemble and replace, which is more convenient to use and is conducive to improving work efficiency.

There are two sets of the first sliding frame 204 and the second sliding frame 208. The first sliding frame 204 and the second sliding frame 208 are both slidably connected to the first bracket 1. The moving directions of the first sliding frame 204 and the second sliding frame 208 are opposite.

[0034] Both the first screw rod 202 and the second screw rod 207 are bidirectional screw rods and have opposite helix directions.

[0035] Start the first motor 201. The first motor 201 drives the first screw rod 202 and the first belt pulley 203 to rotate. The first screw rod 202 drives the first sliding frame 204 to move along the first bracket 1. At this time, the two sets of first sliding frames 204 approach each other. The first belt pulley 203 drives the second belt pulley 206 to rotate through the first belt 205. The second belt pulley 206 drives the second screw rod 207 to rotate. The second screw rod 207 drives the two sliding frames 208 to move away from each other.

[0036] In one embodiment, for the above-mentioned first rolling component 3, the first rolling component 3 includes a second motor 301. The second motor 301 is fixedly connected to the bottom of the first sliding frame 204. A first rolling wheel 302 is fixedly connected to the output shaft of the second motor 301. A first slider 303 is rotatably connected to the bottom of the first rolling wheel 302. The outer surface of the first slider 303 is slidably connected to a first square plate 304. The first square plate 304 is fixedly connected to the first bracket 1.

[0037] The first sliding frame 204 drives the first rolling wheels 302 to approach each other. The first sliders 303 at the bottom of the first rolling wheels 302 move along the first square plate 304 and support the first rolling wheels 302. Pass the steel wire through between the first rolling wheels 302. Start the second motor 301 to drive the first rolling wheels 302 to rotate. The first rolling wheels 302 roll the steel wire and drive the steel wire to move.

[0038] In one embodiment, for the above-mentioned second rolling assembly 4, the second rolling assembly 4 includes a third motor 401, the third motor 401 is fixedly connected to the bottom of the second sliding carriage 208, a second rolling wheel 402 is fixedly connected to the output shaft of the third motor 401, a second slider 403 is rotatably connected to the bottom of the second rolling wheel 402, the outer surface of the second slider 403 is slidably connected to a second square plate 404, the second square plate 404 is fixedly connected to the first bracket 1, and the cross-sectional shapes of the second rolling wheel 402 and the first rolling wheel 302 are different.

[0039] When the second sliding carriage 208 drives the second rolling wheels 402 to approach each other, the first rolling wheels 302 move away from each other. The working principle of the second rolling wheel 402 is the same as that of the first rolling wheel 302, and will not be elaborated here.

[0040] In one embodiment, for the above-mentioned guiding assembly 5, the guiding assembly 5 includes a support column 501, a fourth motor 502 is fixedly connected to the top of the support column 501, a third pulley 503 is fixedly connected to the output shaft of the fourth motor 502, a second belt 504 is arranged on the outer surface of the third pulley 503, the third pulley 503 is drivingly connected to a fourth pulley 505 through the second belt 504, a rotating shaft 506 is fixedly connected to the outer surface of the fourth pulley 505, a connecting plate 507 is fixedly connected to the outer surface of the rotating shaft 506, a first forming cylinder 508 and a second forming cylinder 509 are respectively fixedly connected to the outer surface of the connecting plate 507, and the first forming cylinder 508 and the second forming cylinder 509 are located on the side of the second rolling wheel 402.

[0041] After the steel wire is rolled by the first rolling wheel 302, it enters the inside of the first forming cylinder 508. Both the inside of the first forming cylinder 508 and the second forming cylinder 509 have spiral grooves, and the cross-sectional shape of the grooves matches the cross-sectional shape of the rolled steel wire. The steel wire moves along the spiral groove inside the first forming cylinder 508 to form a spring. When the steel wire is rolled by the second rolling wheel 402, the fourth motor 502 is started. The fourth motor 502 drives the third pulley 503 to rotate. The third pulley 503 drives the fourth pulley 505 to rotate through the second belt 504. The fourth pulley 505 drives the rotating shaft 506, the connecting plate 507, the first forming cylinder 508 and the second forming cylinder 509 to rotate, so that the first forming cylinder 508 and the second forming cylinder 509 exchange positions. At this time, the steel wire rolled by the second rolling wheel 402 can enter the second forming cylinder 509 and move along the spiral groove inside it.

[0042] In one embodiment, for the above-mentioned limiting component 6, the limiting component 6 includes a second bracket 601, and a first electric push rod 602 is fixedly connected to the outer surface of the second bracket 601. There are two groups of the first electric push rods 602, and the movable ends of the two groups of the first electric push rods 602 respectively extend into the first forming cylinder 508 and the second forming cylinder 509.

[0043] When the movable ends of the two groups of the first electric push rods 602 are located in the first forming cylinder 508 and the second forming cylinder 509, the steel wires in the first forming cylinder 508 and the second forming cylinder 509 can be supported and limited to prevent the steel wires from slipping out of the spiral grooves. After the steel wires are wound into springs, the first electric push rod 602 is started, and the movable ends of the first electric push rod 602 move out of the first forming cylinder 508 and the second forming cylinder 509.

[0045] The second electric push rod 702 is started, and the second electric push rod 702 pushes the cutting knife 703 to move, so that the cutting knife 703 cuts off the spring extending out of the first forming cylinder 508 and the second forming cylinder 509.

[0046] Through the above technical solutions: 1. By connecting the displacement component 2, the first rolling component 3 and the second rolling component 4, the moving directions of the first rolling component 3 and the second rolling component 4 are opposite. When the displacement component 2 drives the first rolling components 3 to approach each other, the second rolling components 4 move away from each other, so as to avoid the steel wire. When it is necessary to roll spring steel wires with different cross-sectional shapes, the displacement component 2 drives the first rolling component 3 and the second rolling component 4 to move in opposite directions. At this time, the first rolling components 3 move away from each other to avoid the steel wire, and the second rolling components 4 approach each other for rolling. There is no need to disassemble and replace, which is more convenient to use and helps improve work efficiency. 2. By connecting the first sliding frame 204 with the first rolling wheel 302 and the second sliding frame 208 with the second rolling wheel 402, the first screw 202 and the second screw 207 connected to the first sliding frame 204 and the second sliding frame 208 have opposite helix directions. Furthermore, the moving directions of the first sliding frame 204 and the second sliding frame 208 are opposite. When the first sliding frame 204 drives the first rolling wheels 302 to approach each other, the second sliding frame 208 drives the second rolling wheels 402 to move away from each other. At this time, the first rolling wheels 302 can roll the steel wire, and vice versa. Moreover, the shapes of the first rolling wheel 302 and the second rolling wheel 402 are different, and steel wires with different cross-sectional shapes can be rolled. Only by changing the forward and reverse rotation of the first motor 201 can different rolling wheels be switched, and there is no need to disassemble and replace the first rolling wheel 302 and the second rolling wheel 402, which is more convenient to use and helps improve work efficiency.
