Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figure 1-4 The utility model provides an embodiment: a double-station multi-link cutting machine, comprising a base 1 and a top plate 3 arranged directly above the base 1, eight columns 2 for forming a frame are installed between the base 1 and the top plate 3, a cutting module 4 is installed between the four columns 2 on the same side, and a workpiece can be placed in each of the two cutting modules 4;

[0020] A four-cavity support frame 5 is fixed at the center position of the top of the top plate 3, a dual-axis transmission structure is arranged inside the four-cavity support frame 5, and a gear drive unit 6 for driving the dual-axis transmission structure to rotate is installed on one side of the surface of the four-cavity support frame 5, the dual-axis transmission structure includes a front transmission shaft 8 and a rear transmission shaft 7 rotatably installed on the front and rear sides of the four-cavity support frame 5, a pair of gear transmission structures 9 for power transmission are installed between the rear transmission shaft 7 and the front transmission shaft 8, when the gear drive unit 6 is turned on to work, the gear drive unit 6 drives the front transmission shaft 8 to rotate, and the rear transmission shaft 7 rotates synchronously and in the opposite direction under the connection with the pair of gear transmission structures 9;

[0021] Two connecting rod push structures 12 are symmetrically installed on the outer walls of both sides of the four-cavity support frame 5, and the four connecting rod push structures 12 are all driven by the double-axis transmission structure. A guide cylinder 10 is fixed on the outer wall of the four-cavity support frame 5 on one side of the connecting rod push structure 12, and a sliding column 11 is slidably installed inside the guide cylinder 10. The bottom end of the sliding column 11 is connected to the upper mold of the cutting module 4, and the movable end of the connecting rod push structure 12 is connected to one end of the surface of the sliding column 11. The front transmission shaft 8 and the rear transmission shaft 7 each drive the connecting rod push structures 12 at both ends of themselves to work. For every rotation of the rear transmission shaft 7 and the front transmission shaft 8, the connecting rod push structure 12 moves a cycle. During this cycle, the connecting rod push structure 12 drives the sliding column 11 to move up and down once, that is, the cutting module 4 is driven by the sliding column 11 and performs a cutting, so as to cut the workpiece in the cutting module 4;

[0022] The gear transmission structure 9 includes a driving toothed disc fixed on both ends of the surface of the front transmission shaft 8, and a driven toothed disc fixed on both ends of the surface of the rear transmission shaft 7, the driving toothed disc and the driven toothed disc mesh with each other, the gear drive unit 6 is composed of a reduction motor 601 and a bevel gear transmission structure 602, the reduction motor 601 is installed on one side of the surface of the four-cavity support frame 5, and the bevel gear transmission structure 602 is installed at the output end of the reduction motor 601 and is used to connect the front transmission shaft 8;

[0023] The front transmission shaft 8 is driven to rotate by the reduction motor 601 and the bevel gear transmission structure 602, so as to transmit power to the rear transmission shaft 7 through the gear transmission structure 9. At this time, the connecting rod pushing structure 12 on the outer walls of both sides of the four-cavity support frame 5 can work synchronously under the drive of a motor, and the structure is simple and the operation is stable and reliable.

[0024] The cutting die set 4 includes an upper punch cutting die 402 slidably mounted on four uprights 2 on the same side, and a lower die 401 fixed to the top of the base 1. The top of the upper punch cutting die 402 is fixedly connected to the bottom of the slide column 11. When the upper punch cutting die 402 is driven downward by the slide column 11 and is molded with the lower die 401, the workpiece is cut once by the upper punch cutting die 402.

[0025] The connecting rod pushing structure 12 includes a short connecting rod 1201 fixed at both ends of the rear transmission shaft 7 and the front transmission shaft 8, and a long connecting rod 1202 hinged at the top of the short connecting rod 1201, the bottom end of the long connecting rod 1202 is hinged to the outer wall of the sliding column 11, and a double-wing sleeve 1101 is fixed to one end of the surface of the sliding column 11, and one end of the double-wing sleeve 1101 and the bottom end of the long connecting rod 1202 are hinged to each other. When the connecting rod pushing structure 12 is driven to work by the rear transmission shaft 7 and the front transmission shaft 8, the short connecting rod 1201 rotates with the rear transmission shaft 7 or the front transmission shaft 8 as the center. Since the short connecting rod 1201 and the long connecting rod 1202 are hinged to each other, the short connecting rod 1201 reciprocates to lift the long connecting rod 1202, the double-wing sleeve 1101, and the guide cylinder 10 up and down, and effectively reduces the vibration and deformation of the sliding column 11 during movement through the guide cylinder 10 and the column 2, which helps to ensure high precision and high quality during the cutting process.

[0026] When the embodiment of the present application is in use, the staff first places the workpiece to be cut inside the cutting module 4. At this time, one workpiece can be placed in each of the two cutting modules 4. Then the staff turns on the gear drive unit 6 to work, and the gear drive unit 6 drives the front transmission shaft 8 to rotate, and the rear transmission shaft 7 rotates synchronously and in the opposite direction under the connection with the gear transmission structure 9. At this time, the front transmission shaft 8 and the rear transmission shaft 7 each drive the connecting rod pushing structure 12 at both ends of themselves to work. Every time the rear transmission shaft 7 and the front transmission shaft 8 rotate one circle, the connecting rod pushing structure 12 moves a cycle, and the connecting rod pushing structure 12 moves one cycle during this cycle. The rod pushing structure 12 drives the slide column 11 to rise and fall once, that is, the cutting module 4 is driven by the slide column 11 and performs a cutting operation, so as to cut the workpiece in the cutting module 4. The cutting machine adopts a double-station structure arrangement and can process two metal workpieces at the same time, thereby greatly improving production efficiency. In a production environment requiring high output, the double-station cutting machine can complete the task more quickly, shorten the processing cycle, and increase output. In this process, the use of the connecting rod pushing structure 12, the guide cylinder 10, and the slide column 11 can improve the stability and rigidity of the cutting machine, thereby improving the cutting accuracy.
