DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments.

[0023] Referring to Figure 1 , one of the core support structures of the plate shearing machine is the hoisting frame 1, which is installed on the top of the processing workshop through two air cylinders 2. The two air cylinders 2 not only play a key role in the hoisting frame 1, but also can flexibly drive the hoisting frame 1 to perform lifting operation, so as to conveniently adjust the height position of the plate shearing machine according to actual processing requirements, so as to adapt to plate processing tasks of different thicknesses or sizes.

[0024] Although the bottom plate is not shown in the figure, we can imagine that the bottom plate as the basic support component of the whole plate shearing machine, the fixed shearing cutter 16 arranged thereon cooperates with the shearing cutter 16 movably arranged on the hoisting frame 1 to complete the cutting action of the plate. This combination of fixed cutter and movable cutter is a common design in the field of plate shearing machines, and will not be described in detail here, but the stable and efficient cutting principle is an important basis for ensuring the processing precision and quality of the plate.

[0025] Referring to Figures 2-4 , the rotating groove 4 provides a rotating space for the horizontal screw rod 6, so that the horizontal screw rod 6 can rotate freely therein, and this rotating action is closely connected with the driving motor 3 through a transmission mechanism. The driving gear 7 in the transmission mechanism is installed on the output shaft of the driving motor 3, and when the driving motor 3 starts, the driving gear 7 rotates. The transmission gear 8 engaged with the driving gear 7 is installed on the horizontal screw rod 6, and the driving gear 7 and the transmission gear 8 are both conical gears, and the unique vertical engagement relationship between them can effectively change the transmission direction of the power, and accurately transmit the rotating power of the driving motor 3 to the horizontal screw rod 6, so as to drive the horizontal screw rod 6 to realize stable rotation.

[0026] The movable frame 9 threaded on the horizontal screw rod 6 is an important component, and the brush 17 installed thereon has a special purpose. With the rotation of the horizontal screw rod 6, the movable frame 9 moves transversely along the horizontal screw rod 6, and the brush 17 can clean the surface of the plate in the process, remove dust, debris and other impurities on the plate, and ensure the surface cleanliness of the plate before cutting, which is of great significance to improve the cutting quality and protect the cutting knife.

[0027] Meanwhile, the vertical screw rod 14 in the rotating chamber 13 also plays a key role in the operation of the plate shearing machine. The vertical screw rod 14 is also closely related to the driving motor 3, and can rotate through the power provided by the driving motor 3, thereby driving the lifting frame 15 threaded thereon to move up and down. The cutting knife 16 installed on the lifting frame 15 is adjusted in the up and down position, so as to cooperate with the fixed cutting knife 16 on the bottom plate to complete the precise cutting action of the plate.

[0028] And the movable frame 9 and the brush 17 will not affect the descent of the cutting knife 16.

[0029] In addition, in the upper connecting mechanism, the upper end of the upper connecting rod 10 installed on the movable frame 9 is fixedly connected with the upper piston plate 12, so that when the movable frame 9 moves transversely, the upper piston plate 12 can be driven to move correspondingly in the gas cavity 11 through the upper connecting rod 10. In the lower connecting mechanism, the lower end of the lower connecting rod 19 installed on the stabilizing frame 18 is fixedly connected with the lower piston plate 20, and the lower connecting rod 19 is externally sleeved with a spring 21, and the two ends of the spring 21 are connected with the inner wall of the gas cavity 11 and the outer wall of the lower piston plate 20, respectively. When the movable frame 9 moves, the upper piston plate 12 is driven to move, thereby driving the lower piston plate 20 to move through the gas, and then driving the stabilizing frame 18 to move, so that the stabilizing frame 18 contacts the plate to realize the fixing operation.

[0030] When the utility model is used, the plate is placed on the bottom plate, then the cylinder 2 drives the lifting frame 1 to descend, the lifting frame 1 contacts the vertical outer wall of both sides of the plate to limit, the brush 17 contacts the upper end surface of the plate, then the driving motor 3 is started, under the cooperation of the driving gear 7 and the transmission gear 8, the horizontal screw rod 6 and the vertical screw rod 14 will rotate, when the horizontal screw rod 6 rotates, the movable frame 9 drives the brush 17 to move to clean the surface of the plate, the movable frame 9 also drives the upper piston plate 12 to move through the upper connecting rod 10, the gas in the gas cavity 11 is compressed to drive the lower piston plate 20 to move, the movement of the lower piston plate 20 drives the stabilizing frame 18 to move through the lower connecting rod 19, the stabilizing frame 18 contacts the vertical outer wall and the upper end surface of the plate, and the stability of the plate is ensured.

[0031] At the same time, when the vertical screw rod 14 rotates, the lifting frame 15 descends and drives the cutting knife 16 to descend, thereby completing the shearing operation of the plate.

[0032] The above merely describes a preferred embodiment of the present application, and the protection scope of the present application is not limited thereto. Any skilled person in the art, according to the technical scheme and the inventive concept of the present application, makes equivalent replacement or change within the technical range disclosed by the present application, and all of them should be covered within the protection scope of the present application.
