[0031] Please see the appendix Figure 1-2 This utility model provides an embodiment of a cross-cutting edge shearing intermediate pressure roller 420 device, including a connecting assembly 10, a hydraulic cylinder 20, a transmission assembly 30, and a pressure roller 420 assembly 40. It differs from existing devices where a single pressure roller 420 is typically used, and the pressure roller 420 is pressed down using a disc spring clamp. This method, due to the limited spring force, results in unstable pressure on the steel plate, affecting the cutting quality. This application addresses these shortcomings of the prior art by providing a cross-cutting edge shearing intermediate pressure roller 420 device, as detailed below:

[0032] The connecting assembly 10 includes a connecting portion 110 and a support portion 120. The connecting portion 110 extends vertically and its top end is connected to the frame 50. The first end of the support portion 120 is connected to the frame 50 and is located near the top end of the connecting portion 110. The second end of the support portion 120 cantilevered outward from the first end. The hydraulic cylinder 20 is connected to the second end of the support portion 120, and the driving end of the hydraulic cylinder 20 is vertically retractable. The transmission assembly 30 includes a rotating end 311. The system includes an input end 312 and an output end 313. The input end 312 is spaced between the rotating end 311 and the output end 313. The rotating end 311 is hinged to the bottom end of the connecting part 110, and the input end 312 is hinged to the driving end of the hydraulic cylinder 20. The pressure roller 420 assembly 40 includes a connecting block 410 and at least two pressure rollers 420 arranged side by side. The connecting block 410 is connected to the output end 313, and the pressure rollers 420 are connected to the connecting block 410. The bottom of the pressure rollers 420 is used to press the steel plate.

[0033] Specifically, the cross-cutting edge shearing intermediate pressure roller 420 device in this application includes a connecting assembly 10, a hydraulic cylinder 20, a transmission assembly 30, and a pressure roller 420 assembly 40. The connecting assembly 10 is used to connect with the external frame 50 and to install various components. It includes a connecting part 110 and a support part 120. The connecting part 110 is used to connect with the frame 50 and to the transmission assembly 30, serving as a fulcrum for rotation. The support part 120 is used to install the hydraulic cylinder 20 and is also connected to the frame 50. The transmission assembly 30 is positioned on the top of the connecting part 110 to ensure convenient installation. The hydraulic cylinder 20 serves as the driving source, which is more effective than a disc spring clamp. Its driving end extends and retracts vertically to drive the entire transmission assembly 30 to change its vertical displacement. The transmission assembly 30 is used to drive the pressure roller 420 assembly 40 to switch between pressing and lifting. The transmission assembly 30 can adaptably distribute the direct force of the hydraulic cylinder 20, thereby avoiding excessive hydraulic driving force that could damage the steel plate.

[0034] The transmission assembly 30 includes a rotating end 311, an input end 312, and an output end 313. The rotating end 311 serves as the fulcrum for the rotation of the entire transmission assembly 30 and is hinged to the bottom end of the connecting part 110. Thus, the entire transmission assembly 30 can swing around the rotating end 311 after being pulled by the hydraulic cylinder 20. The input end 312 serves as the force-bearing point and is hinged to the driving end of the hydraulic cylinder 20. The vertical extension and retraction of the driving end of the hydraulic cylinder 20 drives the input end 312 to receive vertical force. The force is directed towards the rotating end 311, which is connected to the bottom of the connecting part 110 and remains stationary. However, it can rotate under the action of the hinge, thereby creating the effect of the transmission component 30 swinging around the rotating end 311. It can be understood that since the rotation amplitude is small, its slight arc change can be ignored, and it is actually an up-and-down swing. The output end 313 then drives the pressure roller 420 component 40 to swing up and down under the action of the swing, thereby realizing the effect of pressing / lifting.

[0035] The pressure roller 420 assembly 40 includes a connecting block 410 and at least two pressure rollers 420 arranged side by side. The connecting block 410 is used to connect the pressure rollers 420 to the output end 313. The pressure rollers 420 are arranged in a parallel manner, which increases the contact area between the pressure rollers 420 and the steel plate and further improves the pressing effect. In a preferred embodiment of this application, considering the convenience of installation and processing cost, the number of pressure rollers 420 is two, while still achieving a sufficient pressing effect. Those skilled in the art can also select the specific number according to actual needs.

[0036] In a preferred embodiment of the present invention, the connecting part 110 is a connecting rod 111, the top end of the connecting rod 111 is hinged to the support of the frame 50, and the bottom end of the connecting rod 111 is hinged to the rotating end 311.

[0037] It should be noted that the connecting rod 111 can serve as a connection, extending downward to a certain position for the rotating end 311 to hinge. In addition, the connecting rod 111 can also reduce vibration and impact during movement and improve the stability of the structure during movement.

[0038] In a preferred embodiment of the present invention, the transmission component 30 is a crank arm 310, and the rotating end 311 and the output end 313 are respectively arranged at both ends of the crank arm 310.

[0039] It should be noted that the crank arm 310 has different extension lengths and structural forms, which allows the rotating end 311 and the output end 313 to be respectively arranged at both ends of the crank arm 310. In this way, the force point (input end 312) is distributed near the middle position, so as to change the lever arm and adjust the torque, thereby dispersing the output force. The direct downward force of the hydraulic cylinder 20 is decomposed and reduced through the structure of the crank arm 310, thereby avoiding the excessive force of the hydraulic cylinder 20 from damaging the steel plate.

[0040] In a preferred embodiment of the present invention, the crank arm 310 is inclined downward from the input end 312 toward the output end 313.

[0041] It is worth noting that this allows the input end 312 to be more inclined towards the steel plate surface, thereby reducing the amount of displacement required for expansion and contraction, and making it easier to press and contact with the steel plate; preferably, the length of the section from the input end 312 to the output end 313 can be set to 450mm to 480mm, which can be set by those skilled in the art according to the actual site installation conditions.

[0042] Furthermore, each of the pressure rollers 420 has a rubber lining layer on its roller surface.

[0043] It should be understood that the rubber lining layer is formed by bonding the processed rubber sheet to the surface of the pressure roller 420 with adhesive, creating a continuous insulating cover layer to prevent scratching the steel plate during the pressure roller 420 process, thus providing protection.

[0044] Furthermore, the diameter of each of the pressure rollers 420 is 150mm to 160mm.

[0045] It should be noted that the larger the diameter of the pressure roller 420, the larger the pressing contact area. Since this application adopts a multi-roller side-by-side arrangement, considering the convenience of installation and saving processing costs, preferably, the diameter of each pressure roller 420 can be set to 150mm to 160mm. Those skilled in the art can select according to actual needs.

[0046] Furthermore, the second end of the support portion 120 extends obliquely upward from the first end.

[0047] It should be noted that since the second end of the bracket 120 is used to connect to the hydraulic cylinder 20, extending the second end of the bracket 120 obliquely upward from the first end can increase the vertical distance between the bracket and the steel plate, thereby increasing the size of the installation space to facilitate the installation of the hydraulic cylinder 20 and the crank arm 310, and also increasing the telescopic distance to facilitate the adjustment of the telescopic state.

[0048] Furthermore, the first end of the support portion 120 is connected to the frame 50 by bolts.

[0049] It is understandable that a long hole extending vertically can be provided at the connection point of the bracket part 120 to the frame 50, and the first end of the bracket part 120 can be connected to the frame 50 by bolts. In this way, the installation position of the bracket part 120 can be finely adjusted vertically, thereby further changing the size of the installation space and the telescopic distance, and improving the structural adaptability.

[0050] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
