Description

Technical Field

[0001] The present application belongs to the technical field of shearing equipment, and more specifically, relates to a shearing mechanism and a shearing device. Background Art

[0002] Shearing machine is a kind of mechanical processing equipment, mainly used for shearing metal sheets. It consists of an upper blade that can move up and down and a fixed lower blade. The shearing of metal is achieved by the interlaced engagement of the upper blade and the lower blade.

[0003] Reference Figure 1 When the shearing machine 10 in the related art shears the steel coil 20, it first places the steel coil 20 on the fixed support plate 30 located on one side of the shearing machine 10. At this time, the distance between the shearing machine 10 and the fixed support plate 30 is usually less than 0.3m. At this time, the steel coil 20 is called a steel strip; then the driving mechanism is used to drive the shearing machine 10 to move away from the fixed support plate 30. When the distance between the shearing machine 10 and the fixed support plate 30 is 1m to 2m, the steel strip is sheared to obtain a steel plate of the required length.

[0004] When the distance between the shearing machine 10 and the fixed support plate 30 becomes larger, for steel strips or steel plates with a thickness ≥5mm, the steel strips or steel plates will not bend downward; however, for steel strips or steel plates with a thickness <5mm, the steel strips or steel plates will bend downward. In this case, the shearing machine 10 is prone to scratching the bent steel strip when it moves away from the fixed support plate 30 to prepare for the shearing operation, thereby causing the bent steel strip to deform; at the same time, the shearing machine 10 is also prone to damage the bent steel plate when it moves closer to the fixed support plate 30 after completing the shearing operation, thereby causing the sheared steel plate to deform or even fold.

[0032] As described in the background technology, at present, the shearing machine is a mechanical processing equipment, which is mainly used for shearing metal plates. It consists of an upper blade that can move up and down and a fixed lower blade. The upper blade and the lower blade are interlaced and engaged with each other to achieve the shearing of the metal. Figure 1When the shearing machine 10 in the related art shears the steel coil 20, it first places the steel coil 20 on the fixed support plate 30 located on one side of the shearing machine 10. At this time, the distance between the shearing machine 10 and the fixed support plate 30 is usually less than 0.3m. At this time, the steel coil 20 is called a steel strip; then the driving mechanism is used to drive the shearing machine 10 to move away from the fixed support plate 30. When the distance between the shearing machine 10 and the fixed support plate 30 is 1m to 2m, the steel strip is sheared to obtain a steel plate of the required length. When the distance between the shearing machine 10 and the fixed support plate 30 becomes larger, for steel strips or steel plates with a thickness ≥5mm, the steel strips or steel plates will not bend downward; however, for steel strips or steel plates with a thickness <5mm, the steel strips or steel plates will bend downward. In this case, the shearing machine 10 is prone to scratching the bent steel strip when it moves away from the fixed support plate 30 to prepare for the shearing operation, thereby causing the bent steel strip to deform; at the same time, the shearing machine 10 is also prone to damage the bent steel plate when it moves closer to the fixed support plate 30 after completing the shearing operation, thereby causing the sheared steel plate to deform or even fold.

[0033] Reference Figure 2 and Figure 3 In order to solve the above problems, according to one aspect of the present application, an embodiment of the present application provides a shearing mechanism, which includes a fixed support part 100, a shearing machine 200 and a follower support part 300, wherein the fixed support part 100 is used to support the product 400; the shearing machine 200 can approach or move away from the fixed support part 100 along a preset direction; the follower support part 300 is connected to the shearing machine 200 and is used to move with the shearing machine 200; the follower support part 300 includes a follower support plate 310, the length direction of the follower support plate 310 is parallel to the preset direction, and the follower support plate 310 is used to support the product 400.

[0034] In the embodiment of the present application, the product 400 is generally a steel strip to be processed or a processed steel plate. In other embodiments, the product 400 may also be other objects to be processed or objects that have been processed. The shearing machine 200 is a conventional shearing device for shearing the product 400. The specific structure of the shearing machine 200 is common knowledge of those skilled in the art and will not be elaborated on here. The follower support part 300 is generally fixedly connected to the shearing machine 200 to move back and forth along a preset direction with the shearing machine 200. The preset direction is generally parallel to the horizontal direction.

[0035] When the shearing mechanism of the present application is used to shear the product 400, the starting end of the product 400 is first driven to move in a direction close to the fixed support part 100 until the starting end of the product 400 is mounted on the fixed support part 100. At this time, part of the product 400 is mounted on the follower support plate 310, and then the shearing machine 200 and the follower support plate 310 are driven to move in a direction away from the fixed support part 100 until they move to the desired stop position. During this process, part of the product 400 is always mounted on the follower support plate 310; then the shearing machine 200 is used to shear the product 400. After the shearing process is completed, the shearing machine 200 drives the follower support part 300 and the product 400 to move in a direction close to the fixed support part 100 until they move to the desired stop position. The follower support plate 310 in the present application not only supports the product 400, but also prevents the product 400 from sagging and warping due to factors such as gravity, thereby preventing the shearing machine 200 from causing damage to the product 400 due to the reciprocating movement along the preset direction, thereby ensuring the integrity of the product 400. At the same time, it can also move with the shearing machine 200 and always support the product 400, thereby ensuring the smooth progress of the shearing operation.

At this time, part of the product 400 is mounted on the follower support plate 310, and then the shearing machine 200 and the follower support plate 310 are driven to move in the direction away from the fixed support part 100 until they move to the desired stop position. During this process, part of the product 400 is always mounted on the follower support plate 310; then the shearing machine 200 is used to shear the product 400. After the shearing process is completed, the shearing machine 200 drives the follower support part 300 and the product 400 to move in the direction close to the fixed support part 100 until they move to the desired stop position.

[0061] In summary, the shearing mechanism and shearing device provided in this embodiment have at least the following beneficial technical effects: when the shearing mechanism of the present application is used to shear the product 400, the starting end of the product 400 is first driven to move in a direction close to the fixed support part 100 until the starting end of the product 400 is mounted on the fixed support part 100. At this time, part of the product 400 is mounted on the follower support plate 310, and then the shearing machine 200 and the follower support plate 310 are driven to move in a direction away from the fixed support part 100 until they move to the desired stop position. During this process, part of the product 400 is always mounted on the follower support plate 310; then the shearing machine 200 is used to shear the product 400. After the shearing process is completed, the shearing machine 200 drives the follower support part 300 and the product 400 to move in a direction close to the fixed support part 100 until they move to the desired stop position. The follower support plate 310 in the present application not only supports the product 400, but also prevents the product 400 from sagging and warping due to factors such as gravity, thereby preventing the shearing machine 200 from causing damage to the product 400 due to the reciprocating movement along the preset direction, thereby ensuring the integrity of the product 400. At the same time, it can also move with the shearing machine 200 and always support the product 400, thereby ensuring the smooth progress of the shearing operation.

[0062] The above are only preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
