Description

Technical Field

[0001] The utility model relates to a trimming device, in particular to a thin piece trimming device, and belongs to the technical field of thin piece processing. Background Art

[0002] In some industrial production processes, some thin parts are usually produced according to the conditions of the equipment. When die-casting thin parts, metal is not easy to fill and needs to be trimmed. At this time, a trimming device is needed to cut off the edge of the thin parts through the trimming knife punch, so that the thin parts can be filled and formed more easily in the subsequent processing.

[0003] However, the existing trimming device can only trim the placed thin parts during use, while the thin parts usually need to be trimmed on all sides. At this time, people need to reach out to the workbench of the equipment to manually adjust the direction of the thin parts to perform corresponding trimming, which is dangerous and not safe. Moreover, the position of the punching blade cannot be adjusted, and the blade needs to be disassembled and reinstalled, which is too troublesome to use and affects people's work efficiency.

[0032] It should be noted that the utility model is a thin-piece trimming device. When in use, the thin piece to be trimmed is placed on the top of the storage table 8, and then the hydraulic cylinder 1 is started. The hydraulic cylinder 1 causes the piston rod 2 to start moving downward, thereby driving the moving plate 5 at the bottom of the piston rod 2 to move downward. As the moving plate 5 moves, the two trimming knives 20 at the bottom of the pressing plate 14 fixedly connected to the bottom of the moving plate 5 through the gear ring 12 are pressed downward, thereby stamping and trimming the thin piece placed on the storage table 8;

[0033] When the other two sides need to be trimmed, start the No. 1 motor 9. The model of the No. 1 motor 9 is not described in detail, and the adaptation equipment shall prevail. The No. 1 motor 9 will drive the No. 1 gear 11 to rotate through the connecting shaft 10, and the gear ring 12 meshing with the No. 1 gear 11 will rotate together. Under the rotation of the gear ring 12, the rotating column 13 fixedly connected to the gear ring 12 will rotate together to drive the bottom pressure plate 14 to rotate, so as to adjust the position direction of the two trimming knives 20 at the bottom of the pressure plate 14. When adjusted to the other two sides of the thin part, stop the No. 1 motor 9, and then start the hydraulic cylinder 1 to punch and trim the thin part.

[0034] When it is necessary to cut the thin piece to different widths, start the No. 2 motor 15. The model of the No. 2 motor 15 is not described in detail, and it is subject to the adapted device. The No. 2 motor 15 drives the No. 2 gear 16 to rotate, and the No. 3 gear 17 meshing with the No. 2 gear 16 also rotates together, thereby driving the threaded rod 18 fixedly connected to one side of the No. 3 gear 17 to rotate. As the threaded rod 18 rotates, the sliders 19 at both ends of the outer side of the threaded rod 18 move in relative directions, so that the trimming knife 20 at the bottom of the slider 19 also moves accordingly, thereby adjusting the trimming width;

[0035] During the stamping and trimming process, when the pressure plate 14 stamps downward, the bottom column 21 at the bottom of the pressure plate 14 will also move accordingly, thereby driving the connecting column 23 connected by the buffer spring 22 to move, so that the fixing plate 24 at the bottom of the connecting column 23 can fix the placed thin parts during stamping, and ensure that the thin parts will not move when the two trimming knives 20 are stamping and trimming. When the device completes trimming, the bottom column 21 will rise upward with the device, and the connecting column 23 and the fixing plate 24 will be reset under the action of the buffer spring 22, so that a certain space is generated between the fixing plate 24 and the storage table 8 for placing other thin parts that need to be trimmed.
