Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] See Figures 1-4 As shown, it includes a frame 1, with side support frames 2 installed on both sides of the frame 1. A horizontal plate is installed on the top of the side support frames 2. The side support frames 2 and the horizontal plate form a door frame-shaped main support frame. An operation indicator light 23 is installed above the horizontal plate. A movable protective structure is provided at the front end of the main support frame. A hydraulic cylinder 8 is installed below the horizontal plate. A cutting head 24 is connected to the piston rod of the hydraulic cylinder 8. Two limit switches 9 are provided on the hydraulic cylinder 8. A trigger rod that works in conjunction with the limit switches 9 is connected to the side of the cutting head 24. An movable hole 6 is opened on the frame 1. The movable hole 6 is located directly below the cutting head 24. Support blocks 7 for placing the cutting items are provided on both sides of the movable hole 6 on the frame 1. A clamping component is connected to both sides of the cutting head 24. Control panels 3 are provided on the left and right sides of the frame 1. The hydraulic cylinder 8 is controlled by a two-hand switch. The two start buttons 4 of the two-hand switch are respectively located on the two control panels 3. One of the control panels 3 is equipped with an emergency stop button 5.
[0023] The clamping assembly includes a fixing plate 10 connected to the side of the pressure head 24. The fixing plate 10 is located directly above the support block 7. The fixing plate 10 has several guide sleeves 14, each guide sleeve 14 has a guide post 13, and the bottom end of the guide post 13 is connected to a pressure plate 11. The fixing plate 10 has several connectors 15. The connectors 15 are downwardly oriented cylindrical structures. The fixing plate 10 has through holes below the connectors 15. Springs 16 are installed in the through holes. The upper and lower ends of the springs 16 are connected to the inner wall of the connectors 15 and the pressure plate 11, respectively. The bottom of the pressure plate 11 has a flexible pad 12.
[0024] The protective structure includes a baffle support frame 17 located on the front side of the main support frame. A rear baffle 18 is provided at the top of the baffle support frame 17. Guide rails 20 are vertically provided on both sides in front of the rear baffle 18 in the baffle support frame 17. A front baffle 21 is installed between the two guide rails 20. Several telescopic cylinders 19 are provided at the top of the baffle support frame 17. The top of the telescopic rod of the telescopic cylinder 19 is connected to the front baffle 21. An observation window 22 is embedded in the front baffle 21. The telescopic cylinders 19 are synchronously controlled with the hydraulic cylinder 8.
[0025] The principle and usage process of this utility model:
[0026] First, place the material to be cut on the two support blocks 7, ensuring the cutting position is directly below the pressure head 24. The operator can then press the two start buttons 4 to activate the hydraulic cylinder 8. The hydraulic cylinder 8 drives the pressure head 24 to press down, and simultaneously the pressure plate 11 presses down. The pressure plate 11 first contacts the material, and during the pressing process, the spring 16 compresses the material to ensure its stability and prevent the material from shifting or even bouncing after being subjected to force. The spring 16 is gradually compressed, and the guide post 13 gradually slides upward along the guide sleeve 14. After the pressure head 24 contacts the material, it applies pressure to cut it. The pressure head 24 will drive the trigger rod to move synchronously. After the trigger rod touches the lower limit switch 9, the hydraulic cylinder 8 stops extending and begins to retract. When the trigger rod touches the upper limit switch 9, the hydraulic cylinder 8 stops working. The flexible pad 12 contacts the material, which can reduce damage to its surface.
[0027] At the same time as the hydraulic cylinder 8 is activated, the telescopic cylinder 19 is also activated simultaneously, pushing the front baffle 21 downward so that it combines with the rear baffle 18 to form a shield, preventing debris from flying and injuring personnel during the cutting process. When the hydraulic cylinder 8 retracts, the telescopic cylinder 19 also retracts automatically to facilitate the removal and placement of materials by the staff. At the same time, the staff can observe the operation progress in real time through the observation window 22.
[0028] It should be understood that the above-described specific embodiments of this utility model are merely illustrative or explanatory of the principles of this utility model and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of this utility model should be included within the protection scope of this utility model. Furthermore, the appended claims are intended to cover all variations and modifications falling within the scope and boundaries of the appended claims, or equivalent forms of such scope and boundaries.
