Abstract
Description
Technical Field
[0001] This utility model relates to the field of cold rolling mill technology, and in particular to a chip-blocking fixture and a cold rolling mill. Background Technology
[0002] During operation, cold rolling mills use rolls to roll aluminum sheets. Due to the deformation of the metal strip, some metal residue adheres to the rolls. Because these fragments are quite hard, they can easily scratch the surface of the aluminum sheet during processing. Simultaneously, the rolling process generates a large amount of heat, and these metal residues on the roll surface can affect the accuracy of transmission control and the quality of the rolled product, potentially preventing the rolling process from being completed. Furthermore, there are many models of cold rolling mills, and equipping each model with its own cleaning tools would increase costs.
[0003] Therefore, there is an urgent need for a chip-blocking fixture and a cold rolling mill to solve the above problems. Utility Model Content
[0004] One objective of this utility model is to provide a chip-blocking fixture that can not only remove debris from the surface of the rolls at any time during the cold rolling process, thereby improving production efficiency, but also is easy to install and highly versatile.
[0005] Based on the above concept, the technical solution adopted by this utility model is as follows:
[0006] A chip-blocking fixture is provided, which can be installed on the body of a cold rolling mill, comprising:
[0007] bristles;
[0008] The fixing mechanism includes two fixing plates and two connecting rods. The fixing plates include a first plate and a second plate arranged at an angle. The first plate is disposed on the side wall of the cold rolling mill body and can rotate relative to the side wall. The first end of one of the connecting rods is connected to one of the second plates, and the second ends of both connecting rods are connected to the brush bristles. The brush bristles press against the rolls of the cold rolling mill body.
[0009] Optionally, the first piece is provided with a first through hole, the side wall is provided with a mounting hole, and the fixing mechanism further includes a first fixing member, which passes through the first through hole and is connected to the mounting hole.

[0015] Optionally, the thickness of the bristle body is L2, where L2 ≥ 5 mm.
[0016] Another objective of this invention is to provide a cold rolling mill that can remove debris from the surface of the rolls at any time during the cold rolling process, thereby improving production efficiency.
[0017] Based on the above concept, the technical solution adopted by this utility model is as follows:
[0018] A cold rolling mill is provided, including a cold rolling mill body and the chip-blocking fixture mentioned above. The cold rolling mill body includes an upper power roll, an upper roll, a lower roll and a lower power roll arranged sequentially from top to bottom, and a product cold rolling channel is formed between the upper roll and the lower roll.
[0019] Two chip-blocking fixtures are provided. The bristles of one chip-blocking fixture are inserted between the upper power roller and the upper roll and press against the upper roll. The bristles of the other chip-blocking fixture are inserted between the lower roll and the lower power roller and press against the lower roll.
[0020] The beneficial effects of this utility model are as follows:
[0021] This utility model proposes a chip-blocking fixture, comprising brush bristles and a fixing mechanism. The fixing mechanism is used to install the brush bristles, enabling them to press against the rolls of the cold rolling mill body, thereby removing metal debris from the rolls during rotation. The fixing mechanism includes two fixing plates and two connecting rods.

[0034] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.
[0035] like Figure 1 and Figure 2As shown, this embodiment provides a chip-blocking fixture 200, including brush bristles 1 and a fixing mechanism 2. The fixing mechanism 2 is used to install the brush bristles 1, enabling the brush bristles 1 to press against the roll 1001 of the cold rolling mill body 100, thereby removing metal debris from the roll 1001 during its rotation. The fixing mechanism 2 includes two fixing plates 21 and two connecting rods 22. The first end of one connecting rod 22 is connected to one fixing plate 21, and the second ends of both connecting rods 22 are connected to the brush bristles 1, with the second ends located at the two ends of the brush bristles 1 respectively along the axial direction of the roll 1001. The fixing plates 21 include a first plate 211 and a second plate 212 arranged at an included angle. The first plate 211 is connected to the side wall of the cold rolling mill body 100, and the second plate 212 is connected to the connecting rods 22 and cooperates with the roll 1001, thereby fixing the chip-blocking fixture 200 onto the cold rolling mill body 100. The fixing plate 21 is set on the side wall of the cold rolling mill body 100, and the first plate 211 abuts against the side wall and can rotate on the plane where the side wall is located. As the position of the first plate 211 on the side wall changes, the relative position of the second plate 212 and the cold rolling mill body 100 also changes, thereby driving the brush 1 connected to the second plate 212 to rotate. In this way, it can be adapted to rolls 1001 of different sizes and improve the versatility of the chip blocking fixture 200.
[0036] Optionally, the first piece 211 has a first through hole, and the side wall has a mounting hole. The fixing mechanism 2 also includes a first fixing member, which passes through the first through hole and connects to the mounting hole. In this embodiment, the mounting hole is a threaded hole, and the first fixing member is a bolt. The shank of the bolt extends into the mounting hole and is threadedly connected to it. The head of the bolt presses against the side of the first piece 211 facing away from the side wall, so that the fixing piece 21 is fixed to the side wall. When it is necessary to adjust the position of the fixing piece 21, the bolt can be loosened to create a gap between the fixing piece 21 and the side wall, thereby facilitating the rotation of the fixing piece 21 relative to the side wall. In this embodiment, the first piece 211 and the second piece 212 are arranged at a right angle, that is, the fixing piece 21 has an L-shaped structure.
[0037] Optionally, a second through hole is provided on the second piece 212, and a threaded section 221 is provided at the first end of the connecting rod 22. The fixing mechanism 2 also includes a nut 23, which is sleeved on the threaded section 221. The threaded section 221 passes through the second through hole, and the nut 23 abuts against the side of the second piece 212 facing the bristles 1. The nut 23 is threadedly connected to the threaded section 221, and the nut 23 can rotate on the threaded section 221 to adjust the length of the connecting rod 22 between the second piece 212 and the roll 1001. In specific implementation, to accommodate a larger size roll 1001, while increasing the angle between the connecting rod 22 and the horizontal plane, the nut 23 can be further rotated so that the nut 23 moves toward the fixing piece 21, thereby increasing the length of the connecting rod 22 between the second piece 212 and the roll 1001.
[0038] Optionally, the length of the threaded section 221 along the length of the connecting rod 22 is L1, where L1 ≥ 100 mm. The length of the threaded section 221 determines the maximum distance that the connecting rod 22 can move along its own axial direction.
[0039] Optionally, the second end of the connecting rod 22 is made of stainless steel. In practice, since the second end is connected to the brush bristles 1, and the brush bristles 1 are soaked in kerosene, using stainless steel can prevent the connecting rod 22 from rusting, thus ensuring the service life of the connecting rod 22.
[0040] Furthermore, the brush bristle 1 includes a mounting plate and a brush bristle body, with the brush bristle body fixed to the mounting plate. The second ends of both connecting rods 22 are connected to the mounting plate. In a specific implementation, the length direction of the brush bristle body and the mounting plate is parallel to the axial direction of the roll 1001. The brush bristle body is fixed to the mounting plate to prevent bending in the middle of the brush bristle body when it is long, thereby affecting the tight contact between the brush bristle 1 and the roll 1001.
[0041] In this embodiment, the bristle body covers the mounting plate, with the upper bristle portion above the mounting plate and the lower bristle portion below the mounting plate fixed. In practice, a single bristle body can be used to cover the mounting plate, and the overlapping sides of the bristle body can be fixed. Because the bristle body has low hardness, there are many ways to fix it; for example, a strap can be used to pass through the bristle body to sew the overlapping sides together.
[0042] Optionally, the thickness of the bristle body is L2, where L2 ≥ 5 mm.
[0043] This embodiment also provides a cold rolling mill, including a cold rolling mill body 100 and the aforementioned chip-blocking fixture 200. The cold rolling mill body 100 includes an upper power roll, an upper rolling roll, a lower rolling roll, and a lower power roll arranged sequentially from top to bottom, with a product cold rolling channel formed between the upper and lower rolling rolls. Two chip-blocking fixtures 200 are provided. The bristles 1 of one chip-blocking fixture 200 are inserted between the upper power roll and the upper rolling roll and press against the upper rolling roll, while the bristles 1 of the other chip-blocking fixture 200 are inserted between the lower rolling roll and the lower power roll and press against the lower rolling roll. The cold rolling mill provided in this embodiment can clean molybdenum sheet debris on the rolling roll 1001 while performing molybdenum sheet cold rolling operations, ensuring the quality of molybdenum sheet cold rolling. Furthermore, the chip-blocking fixture 200 of this cold rolling mill can be adaptively adjusted according to the position and size of the rolling roll 1001, exhibiting strong versatility.
[0044] The above embodiments merely illustrate the basic principles and characteristics of this utility model. This utility model is not limited to the above embodiments. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
