Description

Technical Field

[0001] The utility model relates to the technical field of steel processing, in particular to a novel roller device for a roller table with positive and negative threads after shearing on a cooling bed. Background Art

[0002] A cooling bed is a work surface used in the metallurgical steel rolling industry to effectively cool rolled products. It typically consists of a mechanical transmission system, a water cooling system, a cooling bed work surface, and fixed supports. The cooling bed's primary function is to cool down hot metal products, such as rebar, round steel, and steel pipes, after they have been rolled in the mill, thereby completing the cooling and solidification phase of the rolling process. The cooling bed is crucial for ensuring product quality and subsequent processing steps.

[0003] Post-cooling bed shearing typically refers to the process in the rolling line where steel, after being cooled on a cooling bed, is cut to predetermined lengths by shears. This term describes the next step in the cooling process, namely, cutting to length. In steel rolling production, the cooling bed not only cools the hot metal after rolling but also ensures the flatness and dimensional accuracy of the product during the cooling process, facilitating subsequent shearing.

[0004] When the current ground roller device transports the cooled and sheared rebar, the traditional roller surface is usually smooth, so during the transportation of the rebar, the roller can only transport the rebar but cannot guide the rebar, causing the rebar to easily spread out in the roller and wear the groove plates on both sides, and the finished product to pass through the roller or pile up to one side, which has a great impact on subsequent production passes. It will also cause the secondary cooling bed to be unable to count the number of pieces by the number of knives, resulting in misalignment of the secondary cooling bed material, and quality issues such as incorrect counting of the finished product points. Utility Model Content

[0005] In response to the problems existing in the above-mentioned prior art, the utility model provides a new type of roller device with positive and negative threads after shearing of the cooling bed. The device achieves the technical effect of guiding and conveying threaded steel by arranging two opposite thread patterns on the roller shaft.

[0006] In order to solve the above technical problems and achieve the above technical effects, the present invention is implemented through the following technical solutions:

[0007] The technical solution of the utility model is: a novel roller device for positive and negative threads of a roller table after shearing on a cooling bed, comprising a roller assembly installed in the roller table; the roller assembly is composed of a support roller and a roller drum, the roller being fixedly mounted on the surface of the support roller, and the roller being composed of a positive thread portion, a flat roller portion and a negative thread portion from left to right;

[0008] The left end of the support roller is provided with an auxiliary connecting piece rotatably connected to the inner wall of the roller table, and the right end of the support roller is provided with a transmission connecting piece connected to the drive motor.

[0009] Furthermore, the auxiliary connecting member includes a limit cover fixedly connected to the left end of the support roller, the inner sliding connection of the limit cover is an extension rod, the outer end of the extension rod is detachably provided with a connecting ring that rotates with the inner wall of the roller, and the connecting ring is connected to the extension rod by bolts.

[0010] Furthermore, the transmission connecting member includes a connecting seat provided at the right end of the supporting roller, a mounting rod is installed at the right end of the connecting seat, and the right end of the mounting rod is fixedly connected to the output shaft of the driving motor.

[0011] Furthermore, the limiting cover is fixedly connected to the left end of the supporting roller by bolts.

[0012] Furthermore, a cross rod is fixedly installed on the inner end of the extension rod, and a cross slot adapted to the cross rod is provided inside the support roller, and the length of the cross rod is smaller than the length of the cross slot.

[0013] Furthermore, a groove is provided inside the connecting ring, and a plurality of grooves are arranged at intervals along the surface of the connecting ring. A threaded hole is provided on the surface of the connecting ring, and the connecting ring is fixedly connected to the bearing mounting seat corresponding to the inner wall of the roller by bolts.

[0014] Furthermore, a mounting slot is provided on the surface of the mounting rod, and the length of the mounting slot is smaller than the length of the mounting rod.

[0015] Furthermore, the diameter of the connecting seat is smaller than the diameter of the supporting roller.

[0016] Furthermore, the length of the support roller is greater than the length of the roller.

[0017] Furthermore, the length of the positive thread portion is the same as the length of the negative thread portion.

[0018] The beneficial technical effect of the utility model is as follows: the support roller is installed at the corresponding position in the roller, and the driving motor drives the support roller to rotate through the mounting rod, and the reverse thread part and the positive thread part are respectively arranged on the surface of the roller. When the threaded steel enters the roller and contacts the roller, the positive thread and the reverse thread on the roller can increase the friction on the threaded steel. At the same time, the two opposite threads will gather the threaded steel on both sides inward to prevent them from spreading, avoiding the use of traditional rollers with smooth surfaces, resulting in a lack of friction when conveying the threaded steel, causing the threaded steel to easily spread out in the roller and wear the groove plates on both sides, and causing the finished product to pass through the roller or pile up to one side.

[0025] In order to more clearly understand the technical means of the present invention and implement it according to the contents of the specification, the specific implementation methods of the present invention are further described in detail below in conjunction with the drawings and examples. The following examples are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0026] See attached Figure 1-Figure 4 As shown, a new type of roller device with positive and negative threads after shearing of a cooling bed includes a roller assembly installed in the roller; the roller assembly consists of a support roller 1 and a roller 2, the length of the support roller 1 is greater than the length of the roller 2, and the roller 2 is fixedly installed on the surface of the support roller 1, and the roller 2 is composed of a positive thread portion 22, a flat roller portion 23 and a negative thread portion 21 from left to right, and the length of the positive thread portion 22 is the same as that of the negative thread portion 21. By arranging the positive thread portion 22 and the negative thread portion 21, when the threaded steel enters the roller and contacts the surface of the roller 2, the negative thread on the surface of the negative thread portion 21 and the positive thread on the surface of the positive thread portion 22 are adapted to the threaded steel, increasing the friction force, so that the support roller 1 drives the threaded steel to move in a directional manner through the direction of rotation, preventing the threaded steel from scattering in the roller and wearing the groove plates on both sides, and preventing the finished products from passing through the roller or piling to one side, thereby improving stability.

[0027] When the positive thread portion 22 and the negative thread portion 21 rotate clockwise to convey the threaded steel bars, the positive threads and the negative threads gather the threaded steel bars on both sides of the roller table inward, thereby preventing them from being dispersed.

[0028] The left end of the support roller 1 is provided with an auxiliary connecting piece that is rotatably connected to the inner wall of the roller. The auxiliary connecting piece includes a limit cover 3 fixedly connected to the left end of the support roller 1. The limit cover 3 is fixedly connected to the left end of the support roller 1 by bolts. The internal sliding connection of the limit cover 3 is provided with an extension rod 4. The outer end of the extension rod 4 is detachably provided with a connecting ring 5 that rotates with the inner wall of the roller. The connecting ring 5 is connected to the extension rod 4 by bolts. The right end of the support roller 1 is provided with a transmission connecting piece connected to the drive motor. The transmission connecting piece includes a connecting seat 6 provided at the right end of the support roller 1. The diameter of the connecting seat 6 is smaller than the diameter of the support roller 1. A mounting rod 7 is installed at the right end of the connecting seat 6. The right end of the mounting rod 7 is fixedly connected to the output shaft of the drive motor. A mounting groove 71 is provided on the surface of the mounting rod 7, and the length of the mounting groove 71 is smaller than the length of the mounting rod 7.

[0029] When installing the support roller 1, first fix the mounting rod 7 in the transmission connector to the output end of the drive motor in the roller table, and then rotate the connecting ring 5 in the auxiliary connector to the corresponding position on the inner wall of the roller table.

[0030] After the support roller 1 is installed, the driving motor in the roller conveyor drives the support roller 1 to rotate through the installation rod 7. Then, when the rebar enters the roller conveyor and contacts the surface of the roller 2, the reverse thread surface of the reverse thread part 21 and the positive thread surface of the positive thread part 22 adapt to the rebar, which can increase the friction force, so that the support roller 1 drives the rebar to move in a directional manner through the direction of rotation, preventing it from spreading in the roller conveyor and wearing the groove plates on both sides, and preventing the finished products from passing through the roller conveyor or piling to one side, thereby improving stability.

[0031] Furthermore, a groove 51 is provided inside the connecting ring 5, and a plurality of grooves 51 are arranged at intervals along the surface of the connecting ring 5. A threaded hole is provided on the surface of the connecting ring 5, and the connecting ring 5 is fixedly connected to the bearing mounting seat corresponding to the inner wall of the roller by bolts, and the bolts fix the connecting ring 5 on the bearing mounting seat corresponding to the inner wall of the roller through the threaded holes, and the bearing mounting seat is rotatably connected to the inner wall of the roller through the bearing.

[0032] By providing a plurality of grooves 51 , when the connecting ring 5 contacts the bearing mounting seat corresponding to the inner wall of the track, a slot corresponding to the groove 51 can be provided on the bearing mounting seat for auxiliary positioning.

[0033] A cross rod 41 is fixedly mounted on the inner end of the extension rod 4, and a cross slot 11 adapted to the cross rod 41 is provided inside the support roller 1. The length of the cross rod 41 is less than that of the cross slot 11.

[0034] Furthermore, through the coordinated use of the cross slot 11 and the cross rod 41, the length of the connecting ring 5 can be adjusted according to the actual use environment. When it needs to be extended for installation, the transmission connector at the right end of the support roller 1 is first fixedly connected to the output end of the drive motor, and then the extension rod 4 is pulled outward to allow the cross rod 41 to slide in the inner cavity of the cross slot 11. Subsequently, the extension rod 4 is extended and inserted into the bearing mounting seat corresponding to the inner wall of the roller for fixed installation.

[0035] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. It should be pointed out that ordinary technicians in this technical field can make several improvements and modifications without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
