Detailed Implementation

[0033] The technical solution of this utility model will now be clearly and completely described with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0034] This utility model embodiment specifically provides a scratch-resistant device for a shearing machine. Please refer to... Figures 1-3 The device includes a shearing machine 1, with a shearing opening 11 on the front side of the shearing machine 1. The anti-scratch device also includes a protective cover 2 that is rotatably disposed in front of the shearing opening 11 and a drive assembly that drives the protective cover 2 to move.

[0035] Driven by the drive assembly, the protective cover 2 can be flipped up or down in front of the shearing port 11. This ensures that the protective cover 2 is not flipped when the plate is being fed, allowing the plate to be smoothly fed into the shearing port 11 for shearing. When the plate is being sheared, the protective cover 2 can be rotated forward so that the bottom of the protective cover 2 contacts the upper surface of the plate. When there is debris splashing in the shearing port 11, the protective cover 2 can provide protection for the workers.

[0036] Specifically, the drive assembly includes flip-top assemblies 3 located at both ends of the protective cover 2. The two flip-top assemblies 3 are fixed together by a foot pedal 4, which allows the protective cover 2 to be quickly flipped and reset via the flip-top assemblies 3. The foot pedal 4 frees up the operator's hands, allowing them to directly step on the foot pedal 4 when controlling the flipping of the protective cover 2.

[0037] During implementation, rotating rods 21 are fixedly installed on the left and right sides of the protective cover 2. The rotating rods 21 are rotated in coordination with the shearing machine 1 through the mounting frame 22. The mounting frame 22 is fixedly connected to the outside of the shearing machine 1, so that the protective cover 2 can rotate rapidly with the rotating rods 21 as the fulcrum.

[0038] The protective cover 2 is connected to the flip cover assembly 3 via a rotating rod 21, thereby enabling the flip cover assembly 3 to drive the protective cover 2 to rotate or reset.

[0039] Furthermore, the flip cover assembly 3 includes a rack 31, a gear 32 coaxially fixed with the rotating rod 21, and a slide 33 whose top end is fixed to the rack 31. The rack 31 and the gear 32 mesh with each other. When the rack 31 moves downward in a straight line, it can drive the gear 32 to rotate, thereby causing the rotating rod 21 to rotate and drive the protective cover 2 to rotate forward.

[0040] The outer side of the slide 33 slides in conjunction with the sleeve 34, enabling the slide 33 to be installed and used stably.

[0041] During implementation, the carriage 33 has a polygonal outline, the outer side of the frame 34 is fixed to the shearing machine 1, and the inner wall of the frame 34 has a polygonal outline that matches the carriage 33, so that the carriage 33 can move up and down stably without circumferential rotation.

[0042] Specifically, a reset assembly is provided on the carriage 33 to provide a reset force to the lowered carriage 33.

[0043] The reset assembly includes a pressure plate 35 fixed to the outside of the slide 33. A spring 36 is provided at the bottom of the pressure plate 35. The upper and lower ends of the spring 36 are fixedly connected to the pressure plate 35 and the support plate 37, respectively. The support plate 37 is fixedly connected to the outer wall of the shearing machine 1. Thus, when the slide 33 moves down, it can be quickly reset by the spring 36 after the pressure is released.

[0044] During implementation, the shearing machine 1 has a through-hole 12 on its side that connects to the bottom, and the height of the through-hole 12 is greater than the maximum travel of the carriage 33.

[0045] The foot pedal 4 is fixedly connected to the slide 33 after both ends pass through the opening 12. When the staff steps on the foot pedal 4, it can drive the slide 33 to move vertically downward, thereby causing the gear 32 to drive the protective cover 2 to flip forward for protection. When the foot pedal force is removed, the protective cover 2 can be quickly reset. It is easy to operate and can quickly provide safety protection for the staff.

[0046] The control method of this utility model is to control the device by manually starting and stopping the switch. The wiring diagram of the power element and the supply of power are common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and wiring layout will not be explained in detail.

[0047] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
