[0002] A plate shearing machine is a common plate shearing device. The plate shearing machine makes a reciprocating linear motion of a moving blade relative to a fixed blade, applies a shearing force to steel structure plates of various thicknesses, and makes the plates break and separate according to required dimensions.

[0003] The existing plate shearing machine includes a frame and a loading table for supporting the metal plate to be cut. There is a cutting opening between the frame and the loading table. A cutting plate is arranged at one side of the loading table at the cutting opening. A fixed blade is arranged on the side of the cutting plate away from the loading table. A moving blade is arranged on the side of the frame close to the cutting plate. A spring pressing foot is arranged on one side of the frame. The spring pressing foot is located above the cutting plate. When the plate shearing machine cuts a metal plate, an operator places the metal plate to be cut on the loading table and pushes it into the cutting plate through the cutting opening. The operator adjusts the position of the metal plate so that the part to be cut on the metal plate is located between the fixed blade and the moving blade. Then the spring pressing foot presses the metal plate on the cutting plate. The moving blade moves towards the fixed blade and applies a shearing force to the metal plate to complete the cutting of the metal plate.

[0004] When the existing plate shearing machine is in use, the metal plate is mainly manually placed at the feeding port of the plate shearing machine by workers. Since the plate has a certain weight, it is easy for the plate to be placed offset due to fatigue during long-term manual placement by workers, which affects the cutting quality. Moreover, it is very dangerous for workers' hands to be too close to the feeding port.

[0005] Therefore, it is necessary to provide a new plate shearing machine for processing steel structures to solve the above technical problems. Content of the Utility Model

Specific embodiments

[0023] The present utility model will be further described below with reference to the accompanying drawings and embodiments.

[0024] Please refer to Figure 1 , Figure 2 and Figure 3 , where Figure 1 is the three-dimensional view of the overall structure of the plate shearing machine for processing steel structures provided by the present utility model Figure 1 ; Figure 2 is Figure 1 Schematic enlarged structure diagram of A as shown Figure 3 is the three-dimensional view of the overall structure of the plate shearing machine for processing steel structures provided by the present utility model Figure 2 .

[0025] In the specific implementation process, as Figures 1 - 3 shown, it includes a machine body 1. A support table 3 is provided on one side of the feeding port 2 of the machine body 1. Two groups of sliding grooves 4 are spaced apart on the surface of the support table 3. A moving seat 5 is provided above the support table 3. The bottom of the moving seat 5 is slidably connected to the sliding groove 4. A placing table 6 for placing plates is fixed on the top of the moving seat 5.

[0026] There are two pressing plates 7 symmetrically arranged on the placing table 6. When the size of the steel plate is small, only one pressing plate 7 can be used for pressing and positioning. When the size of the steel plate is large, two pressing plates 7 are used to position the steel plate at the same time. One side of the pressing plate 7 is provided with a sliding column 8 and a cylinder 9. The cylinder 9 is installed on the placing table 6. The output end of the cylinder 9 is fixed with an L-shaped plate 10. The bottom of the L-shaped plate 10 is fixedly connected to the pressing plate 7. The bottom of the sliding column 8 is fixed on the placing table 6. The top of the sliding column 8 penetrates through the L-shaped plate 10 and is fixed with a stop block 11. One side of the bottom of the pressing plate 7 is fixedly connected with a straightening plate 12. The straightening plate 12 is parallel to the feeding port 2. When using this shearing machine, the operator only needs to place the steel structure plate on the placing table 6. When placing the plate, the straightening plate 12 can assist the operator to place the plate in a parallel state with the straightening plate 12. After placing the plate, start the cylinder 9 to drive the pressing plate 7 to move down to fix the plate.

[0027] Both of the two sliding grooves 4 are movably provided with lead screws 13 through bearings. The lead screws 13 penetrate through the moving seat 5, and the lead screws 13 are threadedly connected with the moving seat 5. One end of each of the two lead screws 13 extends out of the support table 3 and is provided with a first bevel gear 14. A plurality of limit seats 15 are fixedly arranged at intervals on one side of the support table 3. A rotating shaft 16 is movably provided through bearings between the plurality of limit seats 15. Two second bevel gears 17 are arranged at intervals on the rotating shaft 16. The two second bevel gears 17 are respectively engaged with the two first bevel gears 14. A motor 18 is arranged on one side of the support table 3. The output end of the motor 18 is connected to the rotating shaft 16 through a coupling. After the plate is fixed, start the motor 18 to drive the rotating shaft 16 to rotate. Under the driving action of the two first bevel gears 14 and the two second bevel gears 17, the two lead screws 13 rotate in the same direction at the same time, so that the moving seat 5 can slide along the sliding groove 4, and finally the plate is conveyed to the feeding port 2 for shearing. During the shearing process, the operator does not need to be too close to the placing table 6, which greatly improves the construction safety of the operator. And by setting the pressing plate 7, the plate can be stably limited, and the stability of the plate during shearing can be greatly improved in cooperation with the positioning device inside the machine body 1, and the shearing effect is improved.

[0028] An inclined seat 20 is arranged directly below the discharging end 19 of the machine body 1. A buffer cushion plate is arranged on the surface of the inclined seat 20. When the plate after shearing falls from the discharging end 19, it will fall on the inclined seat 20 and then slide from the inclined seat 20 to the ground for the operator to collect. Compared with the existing plate directly falling to the ground, the inclined seat 20 can be set to avoid damage to the plate.

[0029] The working principle of the present utility model: When using this shearing machine, the operator only needs to place the steel structure plate on the placing table 6. When placing the plate, the straightening plate 12 can assist the operator to place the plate in a parallel state with the straightening plate 12. After placing the plate, start the cylinder 9 to drive the pressing plate 7 to move down to fix the plate;

[0030] After fixing the plate, start the motor 18 to drive the rotating shaft 16 to rotate. Under the transmission of the two first bevel gears 14 and the two second bevel gears 17, the two lead screws 13 rotate in the same direction at the same time, so that the moving seat 5 can slide along the chute 4, and finally the plate is conveyed to the feeding port 2 for plate cutting. During the plate cutting process, the staff does not need to be too close to the placing table 6, which greatly improves the construction safety of the staff. And by setting the pressing plate 7, the plate can be stably limited, and the positioning device inside the machine body 1 can greatly improve the stability of the plate during plate cutting and improve the plate cutting effect.
