[0002] As a basic processing machine for plate-type processing parts, shearing machine is widely used in the processing of plate parts. It is a machine that uses one blade to make reciprocating linear motion relative to another blade to shear plates. It uses a moving upper blade and a fixed lower blade, and adopts a reasonable blade gap to apply shear force to metal plates of various thicknesses, so that the plates can be broken and separated according to the required size.

[0003] A Chinese utility model (announcement number: CN220127696U) discloses a shearing machine with good protective effect, comprising a support table, a shearing machine housing is arranged on the top of the support table, a first cavity is opened inside the support table, a limit assembly is arranged inside the first cavity, two cylinders are fixedly mounted on the inner top wall of the shearing machine housing, a mounting seat is fixedly connected to the bottom of the cylinder, a shearing blade is movably mounted on the bottom of the mounting seat, a shearing support is arranged on the top of the support table, and a quick-change assembly is arranged between the shearing blade and the mounting seat. The shearing machine with good protective effect, by setting a limit assembly, during the entire operation process, the operator only needs to place the plate to be processed on the top of the support table, and stay away from the shearing mechanism during the operation, thereby reducing safety problems caused by improper operation, and by setting a quick-change assembly, the shearing blade can be quickly disassembled and installed, which is convenient for subsequent replacement or maintenance.

During the entire operation process, the operator only needs to place the plate to be processed on the top of the support table and stay away from the shearing mechanism during the operation to reduce safety problems caused by improper operation. However, when shearing metal plates, debris splashed from the cut surface of the metal plate can easily cause scratches to the human body, posing certain safety hazards. Therefore, how to design a safety protection mechanism for the shearing machine has become a problem that we currently need to solve. Utility Model Content

Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present utility model, "multiple" means two or more, unless otherwise clearly and specifically defined.

[0028] like Figure 1-Figure 4 As shown, the utility model provides a technical solution: an automated handling system for a concrete machine tool, comprising a shearing machine body 1, a shearing machine protection assembly 4 located outside the shearing machine body 1, and a load-bearing plate protection assembly 5 located inside the shearing machine body 1, and a shearing machine control panel 2 is fixedly installed on one side of the surface of the shearing machine body 1.

[0029] The shearing machine protection assembly 4 includes a first motor 401, the output end of the first motor 401 is fixedly connected to a screw body 402, the surface of the screw body 402 is threadedly connected to a first slider 405, a protection plate 404 is fixedly installed on one side of the first slider 405, the inner bottom of the protection plate 404 is fixedly connected to a return spring 406, the surface of the shearing machine body 1 is fixedly installed with a bearing plate 3, the first motor 401 is fixedly installed on the top of the bearing plate 3, and two groups of first motors 401 are provided. Before shearing the metal sheet, the first motor 401 can be started to drive the screw body 402 to rotate, thereby driving the first slider 405 and the protection plate 404 to move downward, so that the elastic extension plate 403 at the bottom of the protection plate 404 contacts the upper surface of the metal sheet, and the setting of the return spring 406 allows the protection plate 404 to adapt to metal sheets of different thicknesses.

[0030] Specifically, the supporting plate protection assembly 5 includes a second motor 501, which is fixedly installed inside the bottom of the shearing machine body 1. The output end of the second motor 501 is fixedly connected to a bidirectional screw rod 502, and the surface of the bidirectional screw rod 502 is threadedly connected to a second slider 503. The top of the second slider 503 is fixedly connected to a limiting plate 504, and a rotating shaft 506 is rotatably installed on the surface of the limiting plate 504. A conveying roller 505 is installed on the surface of the supporting plate 3 through the motor, and the material of the conveying roller 505 is rubber.

[0031] When in use, the metal plate to be sheared can be placed on the supporting plate 3, and the roller motor can be started to drive the conveying roller 505 to rotate, thereby driving the metal plate to move toward the inside of the shearing machine body 1. The second motor 501 can be started to drive the bidirectional screw rod 502 to rotate, thereby driving the second slider 503 and the limit plate 504 to move inward, and limit the metal plates of different sizes. In combination with the provided rotating shaft 506, the transmission of the metal plate will not be interfered with while limiting the left and right movement of the metal plate.

[0032] The working process of the utility model is as follows: when using the safety protection mechanism of the shearing machine, the metal plate to be sheared can be placed on the bearing plate 3 through the support plate protection component 5, and the roller motor is started to drive the conveying roller 505 to rotate, thereby driving the metal plate to move into the inside of the shearing machine body 1, and the second motor 501 can be started to drive the bidirectional screw rod 502 to rotate, thereby driving the second slider 503 and the limit plate 504 to move inward, and limit the metal plates of different sizes, and cooperate with the set rotating shaft 506 to limit the left and right movement of the metal plate without interfering with the transmission of the metal plate. This setting can avoid the friction caused by the direct contact between the metal plate and the surface of the bearing plate 3, which is easy to cause the metal plate and the bearing plate to move. The problem of wear on the surface of the plate 3 can be improved, and at the same time, the problem of manual feeding that easily causes the hands of the staff to be crushed can be improved; through the shearing machine protection component 4, before the metal plate is sheared, the first motor 401 can be started to drive the screw body 402 to rotate, and then drive the first slider 405 and the protection plate 404 to move downward, so that the elastic extension plate 403 at the bottom of the protection plate 404 contacts the upper surface of the metal plate, and the setting of the reset spring 406 makes the protection plate 404 adaptable to metal plates of different thicknesses, which can avoid a large gap between the top of the metal plate and the shearing machine body 1, which causes the cut surface of the metal plate to splash out debris and cause scratches on the human body, and there are certain safety hazards.
