TECHNICAL FIELD
[0001] The present application relates to the technical field of steel processing, in particular to a high-strength steel guide convenient to adjust. BACKGROUND
[0002] In the field of metal pressure processing, the rolling guide is a key equipment. The rolling guide is a key guide device in steel rolling production, which is installed before and after the roll pass. It guides the rolling piece to enter and exit the pass accurately through the principle of rolling friction. The core structure includes rolling bearings, guide rollers, supports and other components. The rolling piece and the guide are in rolling contact instead of sliding friction, which significantly reduces the friction. The characteristics of the rolling guide are as follows: first, the guide stability is strong, which can accurately control the angle and position of the rolling piece, reducing the risk of deviation and winding; second, the damage to the surface of the rolling piece is small, and the rolling contact can reduce the probability of scratches and improve the surface quality of the rolling piece; third, the adjustment is convenient, and different specifications of rolling pieces can be adapted by adjusting the distance between the guide rollers, which has higher flexibility. Modern rolling guides are made of high-chromium cast iron, hard alloy and other wear-resistant materials. Some also use TiC and TiN coating technology to enhance heat and wear resistance. They can withstand high-temperature rolling environments. Their modular design facilitates quick replacement, and they can be used with sensors for state monitoring. They are widely used in high-precision rolling scenes such as bar and wire, and are important equipment for improving rolling efficiency and product quality.
[0003] Currently in the metal pressure processing industry, the rolling guide structure is relatively complex, generally consisting of a guide box body, a pre-guide plate, a guide roller support spring plate, an opening degree adjustment device, a guide roller shaft, a guide roller, and an attached cooling and lubrication system. The guide adjustment uses the opening degree adjustment device to adjust the opening degree of the guide roller support spring plate through the spring. This method has a complex structure, is inconvenient to adjust, and has low strength, which can easily cause accidents due to broken support arms and other reasons. With the further development of the metal pressure processing industry, low-temperature rolling and high-strength alloy steel rolling require higher-strength rolling guides. The contradiction between the current rolling guide and the progress of the industry is increasingly prominent. SUMMARY

[0018] Further, the adjusting mechanism further comprises two guide roller shaft locking nuts 12 and two eccentric locking nuts 13, the two guide roller shaft locking nuts 12 are threadedly installed at the upper ends of the two mounting plates 3, and the two eccentric locking nuts 13 are respectively threadedly installed on the outer surfaces of the two guide roller shaft locking nuts 12.
[0019] Further, a water inlet hole 14 is formed in the upper surface of the guide installation box body 2.
[0020] Further, four connecting bolts 15 are threadedly installed on the lower surface of the base 1, and the upper ends of the four connecting bolts 15 are threadedly penetrated into the interior of the guide installation box body 2.
[0021] Further, a circular hole 16 is formed in the upper surface of the base 1 at the position corresponding to the pre-connection rod 17, and the pre-connection rod 17 is slidably inserted into the interior of the circular hole 16.
[0022] Further, a threaded rod 18 is fixedly connected to the lower surface of the pre-connection rod 17, a rectangular hole 19 is formed in the upper surface of the base 1, and the rectangular hole 19 is communicated with the interior of the circular hole 16.
[0023] Further, a rectangular plate 20 is threadedly installed on the outer surface of the threaded rod 18.
[0024] Further, the pre-connection rod 17 is positioned with the aid of the circular hole 16, and the base 1 and the guide installation box body 2 are fastened by the penetrating type connecting bolts 15, so that a rigid overall structure is formed, the installation of the four connecting bolts 15 is facilitated, the difficulty in fixing the base 1 and the guide installation box body 2 is reduced, and the installation efficiency of the guide is improved.
[0025] Further, the number of adjustment mechanisms is two, and the two adjustment mechanisms are installed on the front two mounting plates 3 and the rear two mounting plates 3 in a front-rear corresponding manner. The guide rollers 9 of the two adjustment mechanisms are oppositely arranged to form a rolling piece guide channel.
[0026] Further, the adjustment mechanism is provided, so that the structure of the guide is very simple, the parts are less than the traditional guide, the processing and manufacturing are convenient, the cost is low, the force structure is simple, there is no hole in the structure to destroy the structural strength, the force is directly applied to the force structure, there is no force transmission between the parts, so it has very high structural strength; the eccentric shaft and the locking structure are very convenient to adjust.
[0027] Further, the inner thread direction of the guide roller shaft locking nut 12 is opposite to the inner thread direction of the eccentric locking nut 13. When the guide roller shaft locking nut 12 appears loose, the eccentric locking nut 13 can be tightened to achieve bidirectional anti-loose.
[0028] Further, the inner wall of the mounting hole 7 is provided with an axial guide groove, and the outer surface of the eccentric sleeve 6 is provided with a guide protrusion. The guide protrusion is slidably embedded in the guide groove to limit the circumferential rotation of the eccentric sleeve 6.
[0029] Further, the upper surface of the rectangular plate 20 is provided with an anti-skid pattern, and the length and width of the rectangular plate 20 are consistent with the length and width of the rectangular hole 19.
[0030] Further, during the rolling operation, the rolled piece first contacts the pre-guide plate 4 on the right surface of the base 1. The pre-guide plate 4 guides the rolled piece to the entrance of the rolled piece guiding channel formed by the guide installation box 2 and the adjusting mechanism through its guide structure. When adjusting the opening degree of the rolling guide, the eccentric locking nut 13 is rotated in the opposite direction using a tool, so that it is disengaged from the engagement state with the guide roller shaft locking nut 12, and the locking restriction on the eccentric sleeve 6 is released. Then, the guide roller shaft locking nut 12 is continuously rotated in the opposite direction, so that its internal thread is separated from the movable sleeve 8, and the pressure on the inner ring of the roller bearing 11 is released. At this time, the adjusting mechanism is in an adjustable state, and then the opening degree adjustment operation is performed. The end of the guide roller shaft 5 is clamped by a wrench tool, and the guide roller shaft 5 is rotated according to the required opening degree. Since the guide roller shaft 5 and the eccentric sleeve 6 are eccentric structures with consistent eccentricity, the position of the guide roller 9 is displaced by the eccentric rotation of the guide roller shaft 5, thereby changing the opening degree of the rolled piece guiding channel. The scale on the eccentric sleeve 6 can be observed during the adjustment process to accurately control the opening degree. After adjusting to the target opening degree, reverse operation is performed for locking and fixing. At this time, the two groups of front and rear symmetrical adjusting mechanisms have adjusted the opening degree through the preset eccentric angle, and the rolled piece enters the channel formed by the guide rollers 9 of the two adjusting mechanisms under the continuous guidance of the pre-guide plate 4. The guide roller 9 rotates flexibly around the guide roller shaft 5 through the internal roller bearing 11, and rotates synchronously with the rolled piece when the rolled piece passes through, thereby reducing the frictional resistance between the rolled piece and the guide roller 9, and ensuring that the rolled piece enters the rolling groove along the preset path stably. During the working process, the water inlet hole 14 on the upper surface of the guide installation box 2 continuously introduces cooling medium, which is directed to the outer surface of the guide roller 9 and the position of the roller bearing 11 through the internal guide structure, thereby reducing the temperature generated by friction of the guide roller and the bearing, avoiding overheating to affect the service life, and at the same time, the locking assembly of the adjusting mechanism always remains stable: the guide roller shaft locking nut 12 and the eccentric locking nut 13 form a bidirectional anti-loosening structure due to the opposite rotation direction, so that even if one of the nuts shows a loosening trend, the other nut will be tightened, ensuring that the eccentric angle of the guide roller shaft 5 and the eccentric sleeve 6 does not deviate, and the guide roller 9 does not move or loosen. The protruding key of the movable sleeve 8 continuously cooperates with the key groove of the guide roller shaft 5 and the eccentric sleeve 6 to ensure that the eccentric angles of the two are synchronized. The axial guide groove on the inner wall of the mounting hole 7 and the guide protrusion of the eccentric sleeve 6 slide and limit, further preventing the eccentric sleeve 6 from rotating in the circumferential direction, ensuring that the opening degree of the rolled piece guiding channel is always stable, and the base 1 and the guide installation box 2 are tightly connected by four connecting bolts 15. The pre-connection rod 17 and the circular hole 16 slide and insert the locking limit of the rectangular plate 20, ensuring that the overall structure does not move relative to the impact of the rolled piece, providing a foundation support for the stable work of the guide.
