Description

Technical Field

[0001] The utility model relates to the technical field of steel production and processing, and more specifically, to a three-roller guide device capable of preventing scratches. Background Art

[0002] Red steel is a high-purity carbon steel obtained by low-temperature rolling process. It has good elongation, high tensile strength and hardness. Red steel is mostly used to manufacture solid bolts, stop valves, gasoline engine parts and mechanical parts.

[0003] After searching, the existing patent (publication number: CN220992346U) discloses a new type of rolling mill dust suppression and anti-scab guide groove, which includes a basic guide groove. The inner wall diameter of the basic guide groove gradually decreases from the input end of the red steel to the output end of the red steel. The peripheral wall of the basic guide groove is provided with a water cooling pipe, and the water cooling pipe is connected to the cooling water source. The inner wall of the basic guide groove is provided with a plurality of groups of water cooling nozzles, and the water cooling nozzles are connected to the water cooling pipe. The water cooling nozzles are used to flush the rust on the surface of the red steel. The present application has the effect of reducing the residence time of rust in the guide groove, preventing scab on the steel surface, and reducing the rise of misted iron oxide to protect the on-site environment and equipment. In the process of realizing the utility model, the inventor found that the existing technology has the following problems:

[0004] The existing guide grooves generate friction when the red steel is being transported due to the contact between the device and the guide of the red steel. The sliding friction usually generates greater wear and heat. However, the friction not only wears the guide grooves, but also leaves scratches or damages on the surface of the red steel, thereby affecting the appearance and anti-corrosion layer of the red steel and causing quality problems. Moreover, since the red steel is made of steel, the parts in contact with it will also wear and damage after long-term use, requiring repair or even complete replacement, which is inconvenient.

[0005] Therefore, in order to solve the above problems, a three-roller guide device for preventing scratches is proposed. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a three-roller guide device that prevents scratches, so as to solve the problems raised in the above-mentioned background technology.

[0007] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a three-roller guide device for preventing scratches, comprising a mounting base, a connecting conduit, a guide roller mounting seat and a rolling guide roller, wherein a conduit bracket is provided on the upper end of the mounting base, the connecting conduit is mounted on the right side of the conduit bracket, the guide roller bracket is mounted on the left side of the conduit bracket, a guide roller mounting seat is provided on the edge of one side of the guide roller bracket, and six groups of guide roller mounting seats are provided;

[0008] A limiting hole is provided at the center of the guide roller mounting seat, a rotating shaft is installed on the opposite surface of each two groups of the guide roller mounting seats, and the rolling guide roller is installed on the outer surface of the rotating shaft, wherein a mounting plate is provided on one side of the three groups of guide roller mounting seats.

[0009] Preferably, each two groups of guide roller mounting seats are connected in an adjacent manner, and the two groups of guide roller mounting seats are combined in a V shape.

[0010] Preferably, both ends of the rotating shaft are movably connected in the inner cavities of the two groups of limiting holes, and the three groups of rotating shafts are arranged in a triangle.

[0011] Preferably, the inner cavities at both ends of each group of mounting plates are provided with bolts, and each group of mounting plates is fixedly connected to one side of the guide roller mounting seat by two groups of bolts. The mounting plates are installed on one side of the guide roller mounting seat to limit one end of the rotating shaft in the inner cavity of the limiting hole.

[0012] Preferably, the outer surface of each group of rolling guide rollers is in an arc shape, and the cavity formed by the arcs between the three groups of rolling guide rollers is a perfect circular structure.

[0013] Preferably, a circular hole is opened in the inner cavity of the connecting duct, the circular structure formed by the three groups of rolling guide rollers is 10 mm smaller than the hole shape of the circular hole, and the arc shape of each group of rolling guide rollers is 5 mm smaller than the hole shape of the circular hole.

[0014] Technical effects and advantages of this utility model:

[0015] Compared with the existing technology, the three-roller guide device that prevents scratches converts sliding friction into rolling friction through the contact between the three sets of guide rollers and the red steel. The friction coefficient of rolling friction is smaller than that of sliding friction, which greatly reduces the friction force on the red steel surface during movement, thereby effectively preventing the occurrence of scratches on the red steel surface.

[0016] Compared with the existing technology, the scratch-proof three-roller guide device realizes modular function through the bolt connection setting of the guide roller bracket and the guide roller mounting seat. Its simple structure enables operators to quickly disassemble it when maintaining or replacing the guide roller, thereby improving work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Example

[0026] As attached Figures 1 to 7 The three-roller guide device shown here is designed to prevent scratches and includes a mounting base 1, a connecting conduit 3, a guide roller mounting base 5, and a rolling guide roller 6. A conduit bracket 2 is provided at the upper end of the mounting base 1. The connecting conduit 3 is mounted on the right side of the conduit bracket 2. The guide roller bracket 4 is mounted on the left side of the conduit bracket 2. A guide roller mounting base 5 is provided on the edge of one side of the guide roller bracket 4. Six groups of guide roller mounting bases 5 are provided.

[0027] A limiting hole 8 is provided at the center of the guide roller mounting seat 5, a rotating shaft 7 is installed on the opposite side of each two groups of guide roller mounting seats 5, and a rolling guide roller 6 is installed on the outer surface of the rotating shaft 7, and a mounting plate 9 is provided on one side of each of the three groups of guide roller mounting seats 5.

[0028] Among them: as the red steel enters, the two ends of the rotating shaft 7 are installed in two groups of limiting holes 8, so that the rolling guide roller 6 on the rotating shaft 7 can rotate simultaneously with it, and the red steel is transmitted by the rolling friction of the rolling guide roller 6. The rolling friction not only reduces energy loss and improves transmission efficiency, but also effectively prevents surface scratches, ensuring that the red steel moves along the predetermined trajectory into the connecting conduit 3, so that the conduit bracket 2 and the guide roller bracket 4 play a guiding role, and the setting of the guide roller mounting seat 5 and the rotating shaft 7 cooperates with the rolling guide roller 6, and is limited by the mounting plate 9, so that the rolling guide roller 6 can stably transport the red steel, further reducing friction, thereby preventing scratches and damage. Example

[0029] Based on Example 1, the solution in Example 1 is further detailed in combination with the following specific working methods. Figures 1 to 7 As shown, see the following description for details:

[0030] As a preferred embodiment, each two groups of guide roller mounting seats 5 are connected in an adjacent manner, and the two groups of guide roller mounting seats 5 are combined in a V shape; further, the two groups of guide roller mounting seats 5 composed of the V shape are divided into three pairs and surround the surface of the guide roller bracket 4, providing a stable support connection method.

[0031] As a preferred embodiment, the two ends of the rotating shaft 7 are movably connected in the inner cavities of the two groups of limiting holes 8, and the three groups of rotating shafts 7 are arranged in a triangular manner; further, the two ends of the rotating shaft 7 are movably connected in the inner cavities of the limiting holes 8 to ensure that it can rotate flexibly during operation without accidentally falling off. The three groups of rotating shafts 7 are arranged in a triangular shape to ensure that the red steel always remains in the center position, which facilitates the rolling guide roller 6 to effectively clamp the red steel and guide it to pass smoothly.

[0032] As a preferred embodiment, the inner cavities at both ends of each set of mounting plates 9 are provided with bolts 10, and each set of mounting plates 9 is fixedly connected to one side of the guide roller mounting seat 5 by two sets of bolts 10. The mounting plates 9 are installed on one side of the guide roller mounting seat 5 to limit one end of the rotating shaft 7 in the inner cavity of the limiting hole 8; further, the mounting plates 9 are installed on one side of the guide roller mounting seat 5 by bolts 10, thereby abutting one end of the rotating shaft 7 to limit it in the inner cavity of the limiting hole 8.

[0033] As a preferred embodiment, the outer surface of each group of rolling guide rollers 6 is arc-shaped, and the cavity formed by the arcs between the three groups of rolling guide rollers 6 is a perfect circular structure; furthermore, the arc-shaped rolling guide rollers 6 generate less friction in the process of contact with the red steel, which can effectively reduce wear and energy loss. The three rolling guide rollers 6 and the rotating shaft 7 are arranged in a triangle at the same time, so that the three groups of arcs are combined into a perfect circle, which surrounds the red steel. The rolling guide rollers 6 support the red steel to ensure the anti-scratch effect.

[0034] As a preferred embodiment, a circular hole 31 is opened in the inner cavity of the connecting conduit 3, and the circular structure composed of three groups of rolling guide rollers 6 is 10 mm smaller than the hole shape of the circular hole 31, and the arc shape of each group of rolling guide rollers 6 is 5 mm smaller than the hole shape of the circular hole 31; further, it ensures that the rolling guide rollers 6 can move in and out freely when guiding the red steel, and provides sufficient clearance to avoid friction and damage caused by obstruction.

[0035] The working process of the present invention is as follows: first, the base 1 is installed to fix the catheter bracket 2 and the guide roller bracket 4. The guide roller bracket 4 is composed of two groups of guide roller mounting seats 5 in a V-shape. Such six groups of guide roller mounting seats 5 are divided into three pairs surrounding the surface of the guide roller bracket 4. Since the two ends of the rotating shaft 7 are installed in two groups of limiting holes 8, the three rolling guide rollers 6 are arranged in a triangle on the outer surface of the rotating shaft 7 and at the same time on the edge of the guide roller bracket 4, so that the three groups of arcs are combined into a perfect circle, surrounding the red steel. The three groups of mounting plates 9 are respectively installed on one side of the three groups of guide roller mounting seats 5 through two groups of bolts 10, thereby abutting one end of the three groups of rotating shafts 7 to limit the inner cavity of the limiting hole 8, and can rotate with the applied force to provide a guide rolling function;

[0036] As the red steel enters, it will abut the outer surface of the rolling guide roller 6, so that the rolling guide roller 6 on the rotating shaft 7 can rotate simultaneously with it, and the red steel is transmitted by the rolling friction of the rolling guide roller 6, ensuring that the red steel moves along the predetermined trajectory into the circular hole 31 in the connecting conduit 3 for subsequent work operations. The conduit bracket 2 and the guide roller bracket 4 play a guiding role. The above is the working principle of the three-roller guide device that prevents scratches.
