Description

Technical Field

[0001] This utility model relates to the field of 20-roll rolling mills, and more specifically, to an intermediate roll pulling device for a 20-roll rolling mill. Background Technology

[0002] A 20-roll mill is used to produce thin metal sheets. It can process metals of a specified thickness according to actual needs and is mostly used in the electronics industry. The existing intermediate roll pulling device can only pull out one intermediate roll during the pulling process, but it is inconvenient to use because it requires a separate removal of the device when placing the roll.

[0003] For example, the specification of the "Intermediate Roll Pulling Device for a 20-Roll Mill" disclosed in Chinese Utility Model Patent (Application No.: CN201620877379.9) states that the current intermediate roll pulling device has some unreasonable aspects, resulting in significant drawbacks during use. Specifically, it is manifested in the following two aspects: First, the pulling hydraulic cylinder is mounted on a bracket at the top of the intermediate roll, making it very inconvenient and costly to replace the intermediate roll due to space constraints. Second, the structural design is unreasonable, resulting in a large overall size and inconvenient installation. The aforementioned patent can corroborate the defects of the existing technology.

[0004] Therefore, we have made improvements to this and proposed an intermediate roll pulling device for a 20-roll mill. Utility Model Content

[0005] The purpose of this invention is to address the problem that existing intermediate roller pulling devices can only pull out one intermediate roller during the pulling process, but require a separate removal device for placement, making them inconvenient to use.

[0006] In order to achieve the above-mentioned objectives, this utility model provides an intermediate roll pulling device for a 20-roll mill to improve the above-mentioned problems.

[0007] The application is as follows:

[0008] A 20-roll mill intermediate roll pulling device includes a support assembly, a lifting assembly fixedly connected to the bottom of the support assembly, an electromagnetic assembly fixedly connected to one side of the support assembly, a gripping assembly slidably connected to the outside of the electromagnetic assembly, and a push bar fixedly connected to one side of the lifting assembly.

[0009] The lifting assembly includes a first lifting block, with a limit strip movably connected to the inner side of the first lifting block, and a telescopic plate provided inside the first lifting block, with limit plates fixedly connected to the top and bottom of the telescopic plate.

[0010] As a preferred technical solution of this application, the support component includes a support block, a positioning hole is provided on one side of the support block, and two arc-shaped support plates are movably connected to the top of one side of the support block, and a push plate is fixedly connected to the top of the arc-shaped support plate.

[0011] As a preferred technical solution of this application, a hydraulic cylinder is fixedly connected to one side of the first lifting block, a T-shaped tube is fixedly connected to the bottom of the hydraulic cylinder, a first L-shaped tube is fixedly connected to both the front and back of the T-shaped tube, a telescopic tube is fixedly connected to the top of the first L-shaped tube, a second L-shaped tube is fixedly connected to the top of the telescopic tube, and a second lifting block is fixedly connected to one side of the second L-shaped tube.

[0012] As a preferred technical solution of this application, the gripping component includes an electromagnetic sliding block, with sliding grooves fixedly connected to both the front and back sides of one side of the electromagnetic sliding block, a positioning block fixedly connected to the top of the electromagnetic sliding block, and a motor fixedly connected to one side of the positioning block. The output shaft of the motor is connected to the gripping handle in a transmission connection.

[0013] As a preferred technical solution of this application, the electromagnetic component includes a power source, an electromagnetic rod is fixedly connected to one side of the power source, and a limiting circular plate is fixedly connected to one side of the electromagnetic rod.

[0014] As a preferred technical solution of this application, the diameter of the sliding groove is tolerantly matched with the diameter of the positioning hole and the diameter of the electromagnetic rod, the size of the limiting plate is matched with the internal space of the first lifting block and the second lifting block, and the size of the telescopic plate is matched with the opening size of the top of the first lifting block and the bottom of the second lifting block.

[0015] As a preferred technical solution of this application, the connection position between the second L-shaped tube and the second lifting block is located above the internal limiting strip of the second lifting block, and the connection position between the first L-shaped tube and the first lifting block is located at the bottom of the internal limiting strip of the first lifting block.

[0016] As a preferred technical solution of this application, the connection between the push plate and the support block is made by a rotating shaft and a torque spring. The top of the support block is provided with an arc-shaped positioning groove, and the shape of the arc-shaped positioning groove on the top of the support block is the same as the shape of the arc-shaped support plate.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] In the scheme of this application:

[0019] 1. This application uses a hydraulic cylinder to move the lifting assembly through a T-shaped tube, a first L-shaped tube, a telescopic tube, and a second L-shaped tube into the first and second lifting blocks, thereby raising the overall height of the lifting assembly and stretching the telescopic tube. Then, the power supply generates a magnetic field on the outside of the electromagnetic rod, which drives the sliding groove to move to the left. Then, the motor drives the gripping handle to grab an intermediate roller. Finally, the power supply generates an opposite magnetic field on the outside of the electromagnetic rod, which can pull out an intermediate roller quickly, thus ensuring the extraction efficiency of the intermediate roller.

[0020] 2. In this application, the other end of an intermediate roller is placed on top of a push plate. The device is then moved to a placement platform. A hydraulic cylinder is used to extract hydraulic oil from the first and second lifting blocks, causing the overall height of the lifting assembly to decrease. The push plate is then rotated by a push bar, causing the intermediate roller to fall from between the two push plates onto the placement platform. As the height of the lifting assembly increases again, the push plate will spring back to its original position under the action of a torque spring, allowing for the next operation. This method places the intermediate roller on the placement platform, saving the need to remove the device and conserving space for operation. Attached Figure Description

[0033] As described in the background art, an intermediate roller pulling device can only pull out one intermediate roller during the pulling process, but it requires a separate removal device for placement, which is inconvenient to use.

Then, the push bar 2 pushes the push plate 104 to rotate, causing an intermediate roller to fall from between the two push plates 104 onto the placement platform. As the height of the lifting assembly 3 rises again, the push plate 104 will spring back to its original position under the action of the torque spring, allowing for the next operation. This process places an intermediate roller on the placement platform, saving the need to remove the equipment and facilitating the saving of operating space.

The power supply 501 then generates a magnetic field on the outside of the electromagnetic rod 502, causing the sliding groove 402 to move to the left. The motor 403 then drives the gripping handle 405 to grip an intermediate roller. Finally, the power supply 501 generates an opposite magnetic field on the outside of the electromagnetic rod 502, allowing the intermediate roller to be extracted quickly, thus ensuring efficient extraction.

[0046] The usage process of the intermediate roll pulling device for a 20-roll mill provided by this utility model is as follows:

[0047] First, the supporting component 1 is aligned with the position where an intermediate roller needs to be removed. Then, the hydraulic cylinder 307, through the T-tube 306, the first L-tube 303, the telescopic tube 304, and the second L-tube 305, guides the lifting component 3 to the first lifting block 301 and the second lifting block 302, thereby raising the overall height of the lifting component 3 and stretching the telescopic tube 304. Then, the power supply 501 activates, generating a magnetic field on the outside of the electromagnetic rod 502, which in turn moves the sliding groove 402 to the left. The motor 403 then drives the gripping handle 405 to grip an intermediate roller. Finally, the power supply 501 activates the electromagnetic rod 502 to grip the outside of the sliding groove 402. An opposite magnetic field is generated on one side to pull out an intermediate roller. After the roller is pulled out, the other end of the intermediate roller is placed on top of the push plate 104. The device is then moved to the placement platform. The hydraulic cylinder 307 is then used to extract the hydraulic oil inside the first lifting block 301 and the second lifting block 302, causing the overall height of the lifting assembly 3 to decrease. The push bar 2 then pushes the push plate 104 to rotate, causing the intermediate roller to fall from between the two push plates 104 onto the placement platform. As the height of the lifting assembly 3 increases again, the push plate 104 will spring back to its original position under the action of the torque spring, allowing for the next operation.
