[0015] Figure 2 This is a schematic diagram of the explosion structure of an embodiment of the utility model. DETAILED DESCRIPTION

[0016] The embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0017] like Figure 1-2 As shown, a double-punch stamping equipment includes a frame 1, a driving member, a coupling 3, an eccentric wheel 5, a dual-process transmission assembly, a first stamping assembly 9, and a second stamping assembly 10. The driving member is not shown in the figure and can be driven by a driving motor, a motor, etc. The two ends of the eccentric wheel 5 are provided with an input end 31 and a pin shaft 32 located on different axes. The driving member is connected to the coupling 3 through the gear set 2. The output shaft of the coupling 3 is connected to the input end 31, and is transmitted through the gear set 2 and the coupling 3, so that the rotation of the eccentric wheel 5 is smoother and more stable.

[0018] In this embodiment, the dual-process transmission assembly includes an eccentric shaft sleeve 21 and a joint bearing assembly. The eccentric shaft sleeve 21 is sleeved on the outside of the eccentric wheel 5. The joint bearing assembly includes a first joint bearing 41 and a second joint bearing 43. The first joint bearing 41 is connected to the second joint bearing 43 through a forward and reverse rotation nut 42. The upper end of the first joint bearing is connected to the pin 32. The joint bearing assembly with this structure can transmit normally when the driving member is in forward and reverse rotation, which is more flexible.

[0019] Taking the automatic punching and buttoning machine that punches holes first and then presses buttons in shoe and clothing processing and manufacturing as an example, in this embodiment, the first punching assembly 9 includes a first connecting member 22, a punch rod 24, and a punching knife 25. The upper end of the first connecting member 22 is hinged to the lower end of the eccentric wheel sleeve 21, the punch rod 24 and the first connecting member 22 are connected by threads, and a locking nut 23 is provided between the punch rod 24 and the first connecting member 22. The punching knife 25 is installed at the lower end of the punch rod 24, and the driving member drives the eccentric wheel 5 to rotate, so that the hinged end of the lower end of the eccentric wheel sleeve 21 swings back and forth, thereby driving the punch rod 24 to move up and down.

[0020] The second stamping assembly includes a second connecting member 51, a mold spindle 53, and a die member 54. The upper end of the mold spindle 53 is fixedly connected to the second connecting member 51. A through hole 52 is provided in the middle of the mold spindle 53 for the punch rod 24 to pass through. The punch rod 24 is inserted into the through hole 52. The through hole 52 provides guidance and limitation for the punch rod to prevent it from shifting, so that the two processes can be processed at the same workstation without the need for workpiece transfer. The die member 54 is provided at the lower end of the mold spindle 53, and the upper end of the second connecting member 51 is connected to the lower end of the second joint bearing 43.

[0021] The working process of this equipment is:

[0022] The driving member rotates through the gear set 2 and the coupling 3, driving the eccentric wheel 5 to rotate. When the eccentric wheel 5 rotates a certain angle, it is transmitted through the eccentric wheel sleeve 21, thereby first driving the punch rod 24 to move downward to perform the first punching process. The eccentric wheel 5 continues to rotate, and the joint bearing assembly drives the mold main shaft 53 to move downward to perform the second pressing process during the position change of the pin shaft 32. Within one rotation cycle of the eccentric wheel 5, the two processes of punching and pressing are completed successively, reducing the loading and unloading of workpieces or the transfer of workstations, and effectively improving production efficiency.

[0023] In this embodiment, a guide seat 11 is provided on the frame 1, and a guide hole 12 is provided on the guide seat 11. The mold main shaft 53 is passed through the guide hole 12 to prevent the mold main shaft 53 from deviating when moving up and down, thereby ensuring the quality of stamping.

[0024] In this embodiment, a bearing 7 is provided between the eccentric wheel 5 and the eccentric wheel sleeve 21. The bearing 7 provides support for the rotation of the eccentric wheel 5 and can reduce friction when the eccentric wheel 5 rotates, thereby increasing the service life of the equipment.

[0025] In this embodiment, the output shaft of the coupling is provided with a limit pressure plate 4, which can effectively limit the deviation of the coupling, ensure the normal operation of the coupling, and also improve the safety and stability of the equipment and reduce the equipment failure rate.

[0026] The embodiments should not be regarded as limiting the present invention, and any non-inventive improvements based on the spirit of the present invention should be regarded as falling within the protection scope of the present invention.
