Description

Spring sheet punching shear device Technical Field The utility model belongs to the technical field of motor part machining, and particularly relates to a spring sheet punching shear device. Background After the motor reduction gearbox completes the central shaft assembly process, a triangular spring plate can be installed on the central shaft so as to facilitate the subsequent installation of the micro-motor rotor. At present, in order to facilitate transportation, triangular shrapnel produced by a production line can be distributed on a material belt in an array manner, and the triangular shrapnel needs to be cut off from the material belt. In the existing punching shear device, an automatic punching shear device special for the triangular elastic sheet is not available, manual assistance is needed in use, and the cutting efficiency is low. For example, chinese patent of publication No. CN216989417U discloses a metal spring punching die, including base and upper supporting seat, the inside motor that is provided with of base, be provided with two pushing components that are used for material loading and unloading on the base, the base upper end is provided with two templates that are used for placing the metal spring that waits to process, upper supporting seat lower extreme is provided with two die-cutting machines that are used for carrying out die-cutting processing to the metal spring, the motor passes through drive assembly and drives two pushing components and do relative horizontal movement, simultaneously the motor passes through drive assembly drives two die-cutting machines and do relative vertical movement simultaneously, and the motor drives two pushing components and two die-cutting machines through drive assembly and do relative movement simultaneously, and the motor drives the inward propulsion of right side pushing components pushes away the metal spring that waits to process to the template of front end, and the motor drives the die-cutting machine through drive assembly simultaneously and descends to contact to the metal spring and carries out die-cutting processing.
