DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0026] The utility model provides a cutting machine for cutting ribs, such as Figs. 1-3 As shown, the frame 1 is fixedly connected with an upper support plate 2, a working plate 3 and a base plate 4 from top to bottom in sequence. The base plate 4 is placed on the ground. A clamping device is provided above the working plate 3. The clamping device is used to clamp the workpiece. One end of the clamping device is fixedly connected to the clamping beam 5, and the clamping beam 5 is fixedly connected to the frame 1. The other end of the clamping device is connected to the clamping drive device; a cutting device is provided on the side of the working plate 3, and the cutting device includes a movable plate 6 and a guide column 7. The guide column 7 is vertically symmetrically arranged on the side of the working plate 3, and the guide column 7 is fixedly connected to the frame 1. Through holes are provided at both ends of the movable plate 6, and the guide column 7 can pass through the through holes so that the movable plate 6 can slide on the guide column 7. The lower end of the movable plate 6 is fixedly connected to a mold knife plate 9, and the upper surface of the movable plate 6 is connected to the lifting drive device. The clamping drive device and the lifting drive device are both connected to the control switch 10.

[0027] The cutting machine for cutting ribs provided by the present invention, in a specific application process, the staff places the workpiece on the working plate 3 and starts the control switch 10, which will start the movement of the clamping drive device. The movement of the clamping drive device will drive the clamping device to move downward, thereby clamping the workpiece so that the workpiece cannot move during the cutting process. At the same time, the lifting drive device will be started, and the lifting drive device will drive the movable plate 6 to slide downward along the guide column 7. The mold blade 9 fixed at the lower end of the movable plate 6 will generate a shear force on the workpiece on the working plate 3 under a large driving pressure, thereby achieving cutting of the workpiece. This device uses a press to apply strong pressure to the workpiece to achieve cutting of the workpiece. Compared with the use of plasma cutting machines or large shearing machines in the prior art, this device saves costs, reduces material waste, and has a simple structure and is easy to operate.

[0028] In this embodiment, the lifting drive device is a hydraulic drive device, comprising a lifting cylinder 11, which is connected to the cutting device. The cylinder end of the lifting cylinder 11 is fixedly connected to the upper support plate 2. The piston rod end of the lifting cylinder 11 passes through the upper support plate 2 and is connected to the upper surface of the movable plate 6 via a lifting flange 12. When the lifting cylinder 11 is in operation, the movement of the piston rod of the lifting cylinder 11 causes the movable plate 6 to slide up and down, thereby driving the mold blade 9 downward to cut the workpiece.

[0029] In this embodiment, the clamping drive device is a hydraulic drive device, which includes a clamping cylinder 13. The clamping cylinder 13 is connected to the clamping device, and the cylinder end of the clamping cylinder 13 is connected to the clamping beam 5. The clamping device includes a clamping plate 14, a clamping flange 15, and a spring 16. The piston rod end of the clamping cylinder 13 is fixedly connected to the upper surface of the clamping plate 14 via the clamping flange 15. One end of the spring 16 is fixedly connected to the clamping flange 15, and the other end of the spring 16 is fixedly connected to the clamping beam 5. The clamping cylinder 13 in this device is a one-way hydraulic cylinder. When the clamping cylinder 13 is in operation, the piston rod end of the clamping cylinder 13 drives the clamping plate 14 downward, thereby achieving compression and fixation of the workpiece. At the same time, the spring 16 will extend due to the tension. When the workpiece is cut, the clamping cylinder 13 stops working. At this time, the elastic force applied to the spring 16 pulls the clamping plate 14 back to its initial state. By using a small and light one-way hydraulic cylinder, the structure of the clamping device is simplified, and the pressure of the clamping device on the workpiece and possible pressure deformation are reduced.

[0030] In this embodiment, the side of the mold blade 9 close to the clamping device is adjacent to the side of the working plate 3 close to the guide column 7. The lower edge of the longitudinal section of the mold blade 9 is set at an angle, and the side of the working plate 3 close to the mold blade 9 is fixedly connected downward with a shear plate 26, the upper surface of the shear plate 26 is flush with the upper surface of the working plate 3, and the lower surface of the shear plate 26 is fixedly connected to the blanking trough 17. The shear plate 26 in this device fits tightly with the two contact surfaces of the mold blade 9, and exerts sufficient pressure on the workpiece when cutting the workpiece, just like scissors, to shear out the ribs, while also achieving a technical effect of a compact structure. In addition, the lower edge of the longitudinal section of the mold blade 9 is set at an angle, so that the mold blade 9 always maintains line contact, rather than surface contact, when cutting the workpiece downward, reducing the shear force on the workpiece and reducing the possibility of deformation of the workpiece.

[0031] In this embodiment, a blanking chute 17 is provided below the work plate 3. The bottom surface of the blanking chute 17 is fixedly connected to the bottom plate 4. The top surface of the blanking chute 17 is provided with a notch 18, which is located directly below the mold blade 9. When the workpiece is cut, the ribs obtained will fall into the blanking chute 17 through the notch 18, making it convenient for workers to take them out.

[0032] In this embodiment, the lift cylinder 11 is connected to the auxiliary hydraulic station 8 via a lift cylinder oil pipe 19, and the clamping cylinder 13 is connected to the auxiliary hydraulic station 8 via a clamping cylinder oil pipe 21. The auxiliary hydraulic station 8 is connected to an oil pump 20 via a solenoid valve 22, which is connected to a pressure gauge 23. The oil pump 20 is connected to an oil pump motor 24, which is connected to a fuel tank 25. In this device, when the oil pump motor 24 is energized, the oil pump 20 draws hydraulic oil from the fuel tank 25. When the pressure gauge 23 reaches a certain threshold, the solenoid valve 22 is activated, and hydraulic oil enters the auxiliary hydraulic station 8. The hydraulic oil in the auxiliary hydraulic station 8 then activates the lift cylinder 11 via the lift cylinder oil pipe 19. Simultaneously, the hydraulic oil in the auxiliary hydraulic station 8 activates the clamping cylinder 13 via the clamping cylinder oil pipe 21. The lift cylinder 11 and the hold-down cylinder 13 share a solenoid valve 22. Because the lift cylinder 11 has a larger surface area, it experiences greater resistance than the hold-down cylinder 13, causing the hold-down cylinder 13 to operate first. Once the hold-down plate 14 has pressed against the workpiece, the hold-down cylinder 13 stops operating. Hydraulic oil then enters the lift cylinder line, activating the lift cylinder 11, which then drives the movable plate 6 downward to cut the workpiece.

[0033] In this embodiment, the length of the shear plate 26 is the same as the length of the mold blade 9, which increases the available range of sizes for cutting ribs and improves applicability.

[0034] This utility model uses specific examples to illustrate the principles and implementation methods of this utility model. The above examples are only used to help understand the method and core concept of this utility model. At the same time, for those skilled in the art, according to the concept of this utility model, there may be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as limiting the utility model.
