Description

Technical Field

[0001] The utility model relates to the technical field of metal processing, in particular to a rolling mill approach bridge correction device. Background Art

[0002] During the copper product production process, raw materials are melted at high temperatures and then reprocessed, sized and adjusted to production requirements before being finalized. During this process, the hot metal blank undergoes multiple extrusion, slitting, and forging operations before its dimensions are gradually adjusted. To ensure stability during transport, a combination of chutes and guide bridges is typically used to transport the blank. However, before the blank enters the next processing step, it often requires alignment and positioning to ensure accurate positioning within the mold or equipment, preventing damage caused by misalignment during transport. Current guide bridge alignment devices have a relatively simple design, using only angled guide grooves to position the blank during transport. A major drawback of this design is that the heavy weight of the blank often causes impact between the guide grooves and the blank during transport. This can cause the blank to become stuck and damaged, impacting processing efficiency. In severe cases, it can also cause positioning errors, leading to slitting errors and increased defect rates, making it unsuitable for current production needs. Utility Model Content

[0027] To make the purpose, technical solution, and advantages of the present invention more clear, the technical solution of the present invention will be described in detail below. Obviously, the embodiments described are only some of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0028] See also Figure 1-Figure 3 As shown, the utility model provides a rolling mill approach bridge correction device, comprising:

[0029] The guide frame 8 is a U-shaped groove structure. Side support plates 9 are symmetrically arranged on both sides of the guide frame 8. The side support plates 9 are welded and fixed to the guide frame 8 to improve the stability of the guide frame 8 when supporting it and provide installation positions for subsequent components. A rotating bracket 14 and a rotating bracket 15 are provided on the bottom surface of the guide frame 8. The rotating bracket 14 and the rotating bracket 15 are arranged on the bottom surface of the guide frame 8, wherein the rotating bracket 15 is close to one end of the side support plate 9, and the rotating bracket 14 is located in the middle of the side support plate 9, and are respectively used to cooperate with the rotating shaft for rotational installation;

[0030] The supporting guide rollers 7 are horizontally arranged on the inner wall of the guide frame 8 to support the bottom surface of the metal blank. There are two groups of supporting guide rollers 7, each group having two symmetrical structures symmetrically arranged on the inner wall of the guide frame 8. When in use, the bottom surface of the metal blank contacts the supporting guide rollers 7, and support is achieved through rolling cooperation to facilitate transportation.

[0031] The limiting guide roller 6 is horizontally arranged above the guide frame 8 and is used to limit the top surface of the metal body. By limiting the height of the metal body surface by the limiting guide roller 6, it can prevent the metal body from falling off the surface of the supporting guide roller 7 due to bouncing during transportation, which affects the safe transportation and positioning of the metal body and cannot meet current practical needs.

[0032] A fixed bracket 1 is provided at one end of the guide frame 8. Side guide rollers 2 are symmetrically arranged above the fixed bracket 1 to position the side walls of the metal blank. The bottom of the fixed bracket 1 is mounted on the factory floor via anchor bolts to ensure support stability. The top of the fixed bracket 1 is flush with the guide frame 8 to facilitate feeding.

[0033] The flip arm 13 is provided on the fixed bracket 1 and is used for rotationally cooperating with the rotating bracket. The flip arm 13 is symmetrically provided on the fixed bracket 1. The end of the flip arm 13 is rotationally cooperating with the rotating bracket 15 via a rotating shaft so as to serve as a fulcrum for adjusting the angle of the guide frame 8.

[0034] The lifting cylinder 12 is rotatably matched with the rotating bracket 14 to adjust the inclination angle of the guide frame 8. The end of the lifting cylinder 12 is rotatably matched with the rotating bracket 14 through the rotating shaft, which can rotatably support the rotating bracket 14 located in the middle of the guide frame 8 and control the support angle of the adjustment frame.

[0035] During use, the lifting cylinder 12 will operate according to work requirements, thereby adjusting the telescopic length to control the support angle of the guide frame 8, thereby achieving different adjustment requirements. When subsequent slitting processing is required, the lifting cylinder 12 drives the guide frame 8 to rotate to a horizontal state, so that the position heights of the guide frame 8, the fixed bracket 1 and the subsequent metal processing mold correspond. At this time, after the previous processing process, the metal blank moves along the conveying structure and first enters the end of the guide frame 8. Due to the long length of the metal blank, after entering the guide frame 8, the bottom surface of its end will first contact the supporting guide roller 7 to achieve initial support for the metal blank, and then the top surface will contact the limiting guide roller 6 to achieve top surface limitation. When the metal blank moves along the supporting guide roller 7, it finally enters the side guide roller 2 between the two side positioning frames 4, and under the action of the side guide roller 2, it can accurately enter the subsequent slitting mold for positioning, thereby improving the quality of subsequent slitting.

[0036] In another embodiment, two symmetrically arranged side positioning frames 4 are provided on the top of the fixed bracket 1, and a guide roller adjustment bracket 3 is horizontally installed on the side positioning frame 4. The side guide roller 2 is rotatably installed in the guide roller adjustment bracket 3, and an adjusting bolt 11 is provided on the side wall of the guide roller adjustment bracket 3. A through hole for the sliding engagement of the adjusting bolt 11 is opened on the side positioning frame 4. The side guide roller 2 can realize the conveying and positioning of metal blanks of different sizes under the cooperation of the guide roller adjustment bracket 3 and the adjusting bolt 11, thereby ensuring the positioning accuracy of the metal blank when entering the subsequent slitting processing positioning mold, and avoiding the influence of conveying deviation on the slitting accuracy.

[0037] In another embodiment, a strip hole is provided on the guide roller mounting bracket 5, and both ends of the limiting guide roller 6 are inserted into the strip hole. A detachable support spring is provided between the inner bottom surface of the guide roller mounting bracket 5 and the end of the guide roller, which can buffer the limiting guide roller 6 after it is subjected to force. Since the support spring is arranged in the guide roller mounting bracket 5, the height of the limiting guide roller 6 can be always maintained at a specified height through the design of the support spring. When in use, the height of the installation base of the support spring can be adjusted to adapt to metal blanks of different sizes for positioning and guiding, thereby minimizing shaking.

[0038] In another embodiment, a through hole for matching installation is opened through the side wall of the guide frame 8, and a rotating bearing seat 10 is provided on the side support plate 9 for rotating with the two ends of the supporting guide roller 7. During installation, the supporting guide roller 7 can be inserted through the through hole and fixed by rotating the bearing seat 10 to achieve limit adjustment of the supporting guide roller 7.

[0039] In another embodiment, a detachable protective cover is mounted on the end face of the guide frame 8. The detachable protective cover can protect the entry portion of the end face of the guide frame 8 to prevent the metal blank from being damaged by collision with the guide frame 8 during transportation. The detachable protective cover can be replaced separately to reduce maintenance costs.

[0040] In another embodiment, the fixing bracket 1 is provided with a slot for the guide frame 8 to be flipped and adjusted. The slotted design can facilitate the cooperation of the guide frame 8.

[0041] In another embodiment, the side guide roller 2 is made of elastic material, such as rubber material. Since the length of the metal blank is usually long, in order to ensure the feeding effect, a fixed bracket 1 can be added between the subsequent workstation and the correction device to further improve the positioning accuracy of the metal blank. The elastic side guide roller 2 can buffer the impact generated during the movement of the metal blank, avoid damage to the metal blank caused by rigid collision, and improve production quality.

[0042] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any modifications or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
