Description

Technical Field

[0001] This utility model relates to the technical field of copper alloy plate and strip production equipment, specifically to an adjustable angle mechanism for the support roller base of a straightening machine roller box. Background Technology

[0002] In the copper strip processing industry, flatness is an important product quality indicator. The flatness requirements are even higher for precision thin copper strips, and straightening thin strips is also more difficult.

[0003] A straightening machine is a device specifically designed for leveling copper strips of different shapes. By adjusting the height of the working rollers at different positions through the lifting and lowering of the support rollers, and by adjusting the roller gap and pressure through the bending rollers of the working rollers, a leveling effect can be achieved for different strip shapes.

[0004] The working roll and the support roll need to be in close contact during operation. After adjusting the height of the support roll according to the shape of the copper strip, the working roll will bend differently. As a result, the working surfaces of the support roll and the working roll will be in contact, resulting in point contact. If the contact of the roll surfaces is not adjusted in time, it will cause defects such as indentations and scratches on the roll surfaces during high-speed and high-pressure rotation of the support roll and the working roll, resulting in various defects on the surface of the strip and affecting the surface quality of the copper strip product. Utility Model Content

[0006] To achieve the above objectives, this utility model discloses an adjustable angle mechanism for the support roller base of a straightening machine roller box with internal sliding. The technical solution adopted is as follows: it includes a straightening roller box base and a support roller. The straightening roller box base is provided with a receiving groove, and the receiving groove is connected to an arc-shaped base. The straightening roller box base is also provided with a clamp that limits the sliding path of the arc-shaped base. The top of the arc-shaped base is connected to the mounting base via an arc-shaped wear-resistant plate. The mounting base and the arc-shaped wear-resistant plate can rotate on the top of the arc-shaped base. By cooperating with the arc-shaped surfaces of the arc-shaped base, the arc-shaped wear-resistant plate, and the mounting base, the support roller can adaptively adjust its angle according to the bending state of the work roller, effectively solving the point contact problem and realizing surface contact between the support roller and the work roller, significantly reducing defects such as roller surface indentations and scratches. Multiple sets of support rollers are rotatably connected to the mounting base.

[0007] As a preferred technical solution of this utility model, both ends of the arc-shaped base are provided with slots that are adapted to the size of the clamp. The clamp cooperates with the slots to limit the sliding direction of the arc-shaped base on the straightening roller box base. The limiting effect of the clamp on the arc-shaped base ensures the accuracy of the adjustment direction.

[0008] As a preferred embodiment of this utility model, the receiving groove includes an inverted trapezoidal groove and a rectangular groove. The arc-shaped base is located in the rectangular groove, and the arc-shaped surface at the top of the arc-shaped base and the bottom of the mounting base are both located in the inverted trapezoidal groove. When the mounting base and the arc-shaped wear-resistant plate rotate at the top of the arc-shaped base, they do not interfere with the straightening roller box base.

[0009] As a preferred embodiment of this utility model, the top of the mounting base is provided with a mounting groove for mounting the support roller, and the bottom of the mounting base is provided with an arc-shaped block, which is connected to the arc-shaped wear-resistant plate by a positioning pin.

[0010] As a preferred technical solution of this utility model, the arc-shaped base has a longitudinal through hole, and a fastening bolt is provided in the through hole. The diameter of the through hole is larger than the outer diameter of the threaded part of the fastening bolt. The arc-shaped base is connected to the mounting base through the fastening bolt. A washer and a disc spring are also provided between the fastening bolt and the arc-shaped base. The cooperation between the fastening bolt and the disc spring ensures the stability of the connection of each component, while providing sufficient room for angle adjustment, thus achieving a synergistic effect.

[0011] As a preferred technical solution of this utility model, the arc-shaped wear-resistant plate is provided in multiple sets, and the arc-shaped wear-resistant plate and the through hole are arranged alternately.

[0012] Compared with the prior art, the beneficial effects of this utility model are: by cooperating with the arc-shaped base, the arc-shaped wear-resistant plate and the arc-shaped surface of the mounting base, the support roller can adaptively adjust its angle according to the bending state of the working roller, effectively solving the point contact problem and realizing the surface contact between the support roller and the working roller, significantly reducing defects such as roller surface indentations and scratches.

[0013] The locking mechanism of the clamp on the curved base ensures the accuracy of the adjustment direction; the cooperation between the fastening bolts and the disc spring ensures the stability of the connection between the components, while providing sufficient room for angle adjustment, achieving a synergistic effect.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0017] like Figures 1 to 5 As shown, this utility model discloses an adjustable angle mechanism for the support roller base of a straightening machine roller box. The technical solution adopted is that it includes a straightening roller box base 7 and a support roller 1. The straightening roller box base 7 is provided with a receiving groove 71, and an arc-shaped base 5 is slidably connected in the receiving groove 71. The straightening roller box base 7 is also provided with a clamp 9 that limits the sliding path of the arc-shaped base 5; both ends of the arc-shaped base 5 are provided with a groove 51 that matches the size of the clamp 9. Under the limitation of the clamp 9, the arc-shaped base 5 can only slide longitudinally on the straightening roller box base 7.

[0018] The clamp 9 is bolted to the straightening roller box base 7 and engages with the clamping grooves 51 at both ends of the arc-shaped base 5 to restrict the movement direction of the arc-shaped base 5, so that it can only slide longitudinally and avoid lateral rotation.

[0019] The receiving groove 71 includes an inverted trapezoidal groove and a rectangular groove, and the arc-shaped base 5 is located in the rectangular groove; The top of the arc-shaped base 5 is connected to the mounting base 2 via an arc-shaped wear-resistant plate 4. The mounting base 2 and the arc-shaped wear-resistant plate 4 can rotate on the top of the arc-shaped base 5. The arc-shaped surface at the top of the arc-shaped base 5 and the bottom of the mounting base 2 are both located within the inverted trapezoidal groove. The straightening roller box base 7 serves as a basic load-bearing component, and a receiving groove 71 is provided on it. The receiving groove 71 includes an inverted trapezoidal groove and a rectangular groove, which are used to accommodate the arc-shaped base 5 and the lower structure of the mounting base 2. like Figure 5 As shown, when the mounting base 2 and the arc-shaped wear-resistant plate 4 rotate on the top of the arc-shaped base 5, they do not interfere with the straightening roller box base 7.

[0020] Multiple sets of support rollers 1 are rotatably connected to the mounting base 2.

[0021] The mounting base 2 has a mounting groove 21 on its top for mounting the support roller 1. The mounting base 2 has an arc-shaped block 22 at its bottom, which is connected to the arc-shaped wear-resistant plate 4 by a positioning pin 8.

[0022] The arc-shaped base 5 is located in the rectangular groove of the receiving groove 71, and its top is a high-precision arc-shaped surface; the arc-shaped wear-resistant plate 4 is attached to the arc-shaped surface of the arc-shaped base 5, and is connected to the arc-shaped block 22 at the bottom of the mounting base 2 through the positioning pin 8, to ensure that the arc-shaped surfaces of the three are consistent, and the surface roughness is controlled below Ra1.6 to ensure smooth relative rotation. The arc-shaped base 5 has a longitudinal through hole 52, and a fastening bolt 3 is provided in the through hole 52. The diameter of the through hole 52 is larger than the outer diameter of the threaded part of the fastening bolt 3. The arc-shaped base 5 is connected to the mounting base 2 through the fastening bolt 3. A washer and a disc spring 6 are also provided between the fastening bolt 3 and the arc-shaped base 5.

[0023] A washer and a disc spring 6 are provided between the fastening bolt 3 and the arc-shaped base 5, which not only provide pre-tightening force to ensure structural stability, but also allow for a certain amount of movement.

[0024] like Figure 3 As shown, the arc-shaped wear-resistant plate 4 is provided in multiple sets, and the arc-shaped wear-resistant plate 4 and the through hole 52 are staggered. The two ends of the arc-shaped wear-resistant plate 4 are also provided with right-angle brackets, which are adapted to the arc-shaped block 22 on the mounting base 2.

[0025] The working principle of this utility model: When the working roll of the straightener is bent and deformed due to the bending roll adjustment, the hydraulic cylinder on the straightener is controlled to extend and push the arc-shaped base 5 to move upward, so that the mounting base 2 is separated from the straightening roll box base 7, providing space for the subsequent rotation of the mounting base 2. The pressure direction of the working roller on the support roller 1 changes, and the pressure is transmitted to the mounting base 2 through the support roller 1. Since the mounting base 2 and the arc-shaped wear-resistant plate 4 are connected by the positioning pin 8, and both can rotate along the arc surface of the arc base 5, under the action of pressure, the mounting base 2 drives the arc-shaped wear-resistant plate 4 to swing adaptively along the arc surface of the arc base 5.

[0026] The arc-shaped base 5 slides only longitudinally under the limiting action of the clamp 9, avoiding the impact of lateral rotation on the adjustment accuracy; the clearance fit between the fastening bolt 3 and the through hole 52 and the elastic buffer of the disc spring 6 provide sufficient space for the swing of the mounting base 2, while ensuring the stability of the structure during the swing.

[0027] Through the above-mentioned oscillation, the angle of the support roller 1 is adjusted in real time according to the bending shape of the work roller, and finally the roller surface of the support roller 1 and the roller surface of the work roller are completely aligned (from point contact to surface contact).

[0028] The circuits and mechanical connections involved in this utility model are common practices used by those skilled in the art, and technical inspiration can be obtained through a limited number of experiments. They are common knowledge.

[0029] Components not described in detail in this article are existing technologies.
