Description

Technical Field

[0001] This utility model relates to the field of metal processing technology, and in particular to a carbon steel rolling guide assembly. Background Technology

[0002] Carbon steel rolling is a processing method that involves pressure stretching of carbon steel materials. It involves heating a carbon steel billet or ingot to a suitable temperature and then using pressure to stretch the carbon steel along its length, reducing its thickness or diameter to obtain a carbon steel product of the desired shape and size. During the carbon steel rolling process, guiding technology is essential to ensure deformation in a predetermined direction and shape, thereby improving product quality and production efficiency.

[0003] In existing technologies, the contact area between carbon steel material and the guide module is large during the rolling process, making wear a particularly prominent issue. During carbon steel rolling, especially cold-rolled carbon steel, lubricating oil is required to reduce friction between the rolls and the steel plate, lower energy consumption and equipment wear, prevent material sticking to the rolls to ensure surface finish, and control rolling temperature (frictional heat can lead to localized overheating and deformation).

[0004] Traditional lubrication methods mainly involve applying the lubricant, which is not very effective and is cumbersome and time-consuming. This not only leads to unnecessary waste of resources but also shortens the lifespan of the guide module and increases maintenance costs and operational complexity. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a novel carbon steel rolled guide block that can simultaneously lubricate the side and bottom surfaces of the carbon steel material and the guide module.

[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows:

[0007] A carbon steel rolling guide assembly includes: a base, with longitudinally arranged baffles fixedly connected to both sides of the top of the base; a lower fixed plate slidably connected to the base; a transmission roller disposed on the side of the lower fixed plate away from the base; the transmission roller includes a lubrication chamber fixedly connected to the lower fixed plate; an upper fixed plate fixedly connected to the side of the lubrication chamber away from the lower fixed plate; a transmission housing rotatably connected to the surface of the lubrication chamber; a lubrication port disposed on the side of the lubrication chamber near the upper top plate; a lubrication hole formed on the side of the lubrication chamber away from the baffles; and a lubrication aperture formed on the side of the transmission housing away from the baffles. Movement of the carbon steel material causes the transmission housing to rotate. As it rotates, the lubrication hole and the lubrication aperture coincide, and when they coincide, the lubricant in the lubrication chamber flows out through the lubrication hole from the lubrication aperture.

[0008] The injection hole can be used to inject lubricant into the lubrication chamber using an injection tool, and the lubrication hole is slightly smaller than the lubrication cavity.

[0009] The above plan further includes:

[0010] A pressure-relieving box is fixedly connected to the side of the upper fixed plate near the baffle, and a lower fixed plate is fixedly connected to the side of the pressure-relieving box away from the upper fixed plate.

[0011] A spring is provided on the side of the pressure relief box near the baffle, and a spring plate is fixedly connected to the side of the spring near the side plate.

[0012] The springs are arranged in a regular and orderly manner to prevent uneven force distribution.

[0013] The spring plate is rotatably connected to a threaded rod on the side near the baffle, and the threaded rod passes through and is rotatably connected to a side plate.

[0014] A handwheel is fixedly connected to the side of the threaded rod away from the spring plate.

[0015] The base has a sliding groove, and a support leg is slidably connected to the sliding groove. A lower fixing plate is fixedly connected to the end of the support leg away from the sliding groove.

[0016] A drive roller is rotatably connected through the bottom positions on both the left and right sides between the two baffles, and a calendering roller is rotatably connected through the top positions on both the left and right sides between the two baffles.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] 1. In use, the carbon steel rolling guide assembly of this utility model has a small contact area and minimal wear because the side of the carbon steel material contacts the side of the transmission roller. During the movement of the carbon steel material, the transmission housing rotates. When the transmission housing reaches a certain position, lubricant in the lubrication chamber flows out from the lubrication hole onto the surface of the transmission housing for lubrication. A portion of the lubricant also flows onto the lower fixed plate under gravity to lubricate the lower contact surface between the carbon steel material and the guide module, thus simultaneously lubricating both the side and bottom contact surfaces of the carbon steel material and the guide module. Lubricant can be added simply by injecting it through the lubrication hole at the top of the rolling guide assembly.

[0019] 2. When the carbon steel rolling guide assembly of this application is in use, under the action of the side spring plate, when the guide assembly clamps the carbon steel material, there is a buffer space under the action of the elastic force, which effectively clamps the material without excessively squeezing the material, and at the same time reduces the damage to the guide module.

[0020] 3. When using the carbon steel rolled guide assembly, the support legs at the bottom of the guide module can effectively support the guide module, eliminating the damage to the side threaded rod caused by gravity on the carbon steel material, and helping to extend the service life of the threaded rod.

[0028] The technical solution of this utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] Example 1

[0030] like Figures 1-6 As shown, a carbon steel rolling guide assembly includes: a base 13, with longitudinally arranged baffles 1 fixedly connected to both sides of the top of the base 13, a lower fixed plate 3 slidably connected to the base 13, a transmission roller provided on the side of the lower fixed plate 3 away from the base 13, the transmission roller including a lubrication chamber 17 fixedly connected to the lower fixed plate 3, an upper fixed plate 11 fixedly connected to the side of the lubrication chamber 17 away from the lower fixed plate 3, a transmission housing 9 rotatably connected to the surface of the lubrication chamber 17, an injection hole 8 provided on the side of the lubrication chamber 17 near the upper fixed plate 11, a lubrication hole 14 opened on the side of the lubrication chamber 17 away from the baffles 1, and a lubrication hole 10 opened on the side of the transmission housing 9 away from the baffles 1.

[0031] The movement of the carbon steel material causes the transmission housing 9 to rotate. As it rotates, the lubrication hole 14 and the lubrication hole 10 coincide. When they coincide, the lubricant in the lubrication chamber 17 flows out from the lubrication hole 10 through the lubrication hole 14.

[0032] Drive rollers 5 are rotatably connected through the bottom positions on both the left and right sides between the two baffles 1, and calendering rollers 4 are rotatably connected through the top positions on both the left and right sides between the two baffles 1.

[0033] The working principle of this utility model carbon steel rolling guide assembly is as follows: When using the device, the operator injects lubricant into the lubrication chamber 17 through the injection hole 8 in advance. During operation, the carbon steel material to be rolled is placed between the rolling roller 4 and the drive roller 5, and the external drive equipment is started to roll the carbon steel. The positions of the rolled carbon steel plate and the guide module are adjusted so that the carbon steel plate is clamped on the lower fixed plate 3. Then, the carbon steel plate moves to the right under the action of the drive roller 5. Under the action of friction, the carbon steel plate drives the transmission housing 9 to rotate. When the transmission housing 9 rotates, the lubrication hole 14 on the lubrication chamber 17 is blocked by the transmission housing 9, and the lubricant will not flow out. When the transmission housing 9 rotates to a certain position, the lubrication hole 10 on the transmission housing 9 coincides with the lubrication hole 14 on the lubrication chamber 17. The lubricant in the lubrication chamber 17 flows out from the lubrication hole 10 through the lubrication hole 14 to the surface of the transmission housing 9 and contacts the carbon steel plate. At the same time, some lubricant will slide down onto the lower fixed plate 3 under the action of gravity and contact the lower surface of the carbon steel plate. This lubricates the two contact surfaces of the guide module and the carbon steel material on the side and the bottom, reducing damage to the guide module and helping to improve the service life of the guide module.

[0034] Example 2

[0035] like Figures 1-6 As shown, a pressure-relieving box 16 is fixedly connected to the side of the upper fixed plate 11 near the baffle 1, and a pressure-relieving box 16 is fixedly connected to the side of the lower fixed plate 3 near the baffle 1. A spring 15 is fixedly connected to the side of the pressure-relieving box 16 near the baffle 1, and a spring plate 18 is fixedly connected to the side of the spring 15 near the baffle 1. A threaded rod 12 is rotatably connected to the side of the spring plate 18 near the baffle 1, and the threaded rod 12 passes through and is rotatably connected to the side plate 1. A handwheel 2 is fixedly connected to the side of the threaded rod 12 away from the spring plate 18. A sliding groove 6 is provided on the base 13, and a support leg 7 is slidably connected to the sliding groove 6. The lower fixed plate 3 is fixedly connected to the end of the support leg 7 away from the sliding groove 6.

[0036] The working principle of the carbon steel rolling guide assembly in this embodiment is as follows: Rotating the handwheel 2 drives the threaded rod 12 to rotate. The threaded rod 12 is rotatably connected to the spring plate 18. The rotation of the handwheel 2 causes the spring plate 18 to move. When the handwheel 2 rotates clockwise, the spring plate 18 moves and compresses the spring 15, which is fixedly connected to the pressure relief box 16, generating a pushing force. Simultaneously, the support leg 7 is slidably connected to the slide groove 6. Under the action of the spring's pushing force, the guide module moves closer. When the handwheel 2 rotates counterclockwise, the spring plate 18 moves and stretches the spring 15, which is fixedly connected to the pressure relief box 16, generating a pulling force. Simultaneously, the support leg 7 is slidably connected to the slide groove 6. Under the action of the spring's pulling force, the guide module moves away. After the carbon steel plate is behind the lower fixed plate 3, rotating the handwheel 2 causes the transmission roller to press against the carbon steel plate.

[0037] The above are merely preferred embodiments of this utility model, but the scope of protection of this application is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and concept of this utility model, should be covered within the scope of protection of this utility model.
