cushion plate punching device, as shown in The utility model discloses an automobile cushion plate punching device, as shown in The utility model discloses an automobile cushion plate punching device, as shown in The utility model discloses an automobile cushion plate punching device,
[0024] It should be noted that, since natural fibers belong to a non-continuous medium and have high elasticity and toughness, the punched part of the automobile cushion plate is prone to deformation and stretching under the action of stamping, the waste material at the punched part is not fully broken, and burrs or even flying filaments are easily generated on the inner side wall of the punched hole. The traditional punch form and device cannot meet the requirements of punching. In the embodiment, the rotating cutting type punching operation can be performed on the automobile cushion plate by moving the rotating sleeve 9 downward during rotation, thereby avoiding the problem that the automobile cushion plate made of natural fibers is prone to burrs or even flying filaments due to high elasticity and toughness during traditional hard punching, and the burrs and flying filaments generated during punching can be removed by using the rotating sleeve 9 with heat.
[0025] Specifically, in the embodiment, the scheme mainly includes a rotating sleeve 9, a cutter 10, a heating column 17, and a pressing ring 19. When punching the automobile cushion plate made of natural fibers, the automobile cushion plate is placed on the base 1, and the punching position is located directly above the through hole 2. When performing the punching operation, the electric push rod one 6 drives the lifting plate 7 to move downward through the output end on one side of the electric push rod one 6, and the rotating sleeve 9 and the pressing ring 19 move downward synchronously. The pressing ring 19 first contacts the automobile cushion plate. As the lifting plate 7 continues to move downward, the spring 21 between the lifting plate 7 and the limiting ring 20 is compressed, and the spring 21 is used to tightly press the automobile cushion plate. At this time, the electric motor 12 drives the driving gear 13 to rotate at a high speed through the output end on one side of the electric motor 12. The driving gear 13 and the driven gear 11 are connected through meshing. The driven gear 11 rotates to drive the rotating sleeve 9 to rotate at a high speed. When the cutter 10 at the bottom of the rotating sleeve 9 contacts the automobile cushion plate, the cutter 10 performs annular cutting, and the rotating sleeve 9 is heated by the heat generated by the working of the heating column 17. As the rotating sleeve 9 moves downward during rotation, the rotating sleeve 9 contacts the inner side wall of the punched hole of the automobile cushion plate, and the burrs and flying filaments are removed by using heat. After punching is completed, the electric push rod two 15 drives the heat insulation disc 16 and the heating column 17 to move downward through the output end on one side of the electric push rod two 15. The heating column 17 pushes the waste material generated during punching out of the rotating sleeve 9.
[0026] As shown in the further preferred embodiment of the utility model, Figs. 1-2 The center of the cross section of the through hole 2, the rotating sleeve 9, and the heating column 17 is on the same vertical axis.
[0027] In the embodiment, the same vertical axis is arranged to avoid friction or misalignment between the through hole 2 and the rotating sleeve 9, and to ensure that the heating column 17 accurately penetrates the rotating sleeve 9.
[0028] As shown in the further preferred embodiment of the utility model, Fig. 4 The bottom of the cutter 10 is provided with a sharp tip, and the side outer wall of the cutter 10 is provided with a cutting edge.
[0029] In the embodiment, the sharp head can pass through the automobile cushion plate, and the blade can cut the automobile cushion plate.
[0030] In the further preferred embodiment of the utility model, as shown in the figure, Fig. 3 The driven gear 11 and the driving gear 13 are connected through the gear engagement.
[0031] In the embodiment, the gear transmission is realized through the engagement connection, so that the driving gear 13 can drive the driven gear 11 to rotate after rotating.
