[0001] The utility model belongs to the field of stamping, and in particular relates to a motor shaft cam stamping device. Background Art

[0002] Generally, one-piece molded parts are stamped. However, in today's stamping process, it takes a long time for the stamping block to move to the stamping original part, and it also takes a long time for the stamping block to return to its original position, which greatly increases the stamping time and reduces the efficiency of stamping.

[0014] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solution in the embodiment of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiment of the present invention.

[0015] As shown in FIG1-2 , a motor shaft cam punching device includes a base 10 , characterized in that: a gantry 11 is fixed on the base 10 , and a punching assembly is installed on the top of the gantry 11 ;

[0016] The stamping assembly includes a first piston cylinder 12 located at the center of the gantry 11, a first piston 14 is movably connected in the first piston cylinder 12, a piston rod 13 is fixed on the first piston 14, the piston rod 13 passes through the first piston cylinder 12 and extends to the outside, a hydraulic oil port 21 is also fixed on the outer peripheral side of the first piston cylinder 12, a second piston cylinder 19 is fixed on the first piston cylinder 12, the second piston cylinder 19 is hollow, and its bottom is connected to the first piston cylinder 12, a second piston 20 is slidably connected in the second piston cylinder 19, a spring is fixed between the second piston 20 and the bottom of the second piston cylinder 19, a first piston group is provided in the first piston cylinder 12, a second piston group is provided in the second piston cylinder 19, a motor 16 is also fixed on the gantry 11, a motor shaft 17 is provided on the motor 16, a bracket 15 is also fixed on the gantry 11, the motor shaft 17 extends into the bracket 15, and is rotatably connected to the bracket 15, a cam 18 is mounted on the motor shaft 17, and the second piston group is squeezed by the cam 18.

[0017] During use, when stamping is required, the device is started, the hydraulic oil pump is started, and the first piston 14 is squeezed by the hydraulic oil, so that the piston rod 13 performs a stamping action. At the same time, the motor 16 is also started, and the cam 18 is driven to rotate through the motor shaft 17. As the raised part of the cam 18 contacts the second piston 20, the second piston 20 can be driven to compress the spring to move to the side close to the base 10, thereby squeezing the hydraulic oil in the second piston cylinder 19 into the first piston cylinder 12 to accelerate the movement speed of the piston rod 13, so that it can quickly contact the stamping original part for stamping. Then the hydraulic oil pump absorbs the hydraulic oil and retracts the piston rod 13. At this time, the cam 18 also turns from the raised part to the non-raised part, and the spring rebound drives the second piston 20 to move upward, absorbing the hydraulic oil in the first piston cylinder 12, so that the piston rod 13 can be quickly retracted, thereby saving stamping time and greatly increasing stamping efficiency.

[0018] Obviously, the described embodiments are only a part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.
