The invention discloses a motor iron core punching progressive die with a stacking discharging mechanism, and relates to the field of blanking dies. For a long time, motor iron core stator and rotor sheets are mostly manually stacked when discharged from a progressive die, and the production cost of manufacturers is increased by adopting the original operation mode for production due to continuous increasing of the labor cost. According to the motor iron core punching progressive die, vertical sheet falling guide needles driven by up-and-down acting air cylinders are arranged in a blanking hole in the lower side of a stator blanking female die of the progressive die, and a lower die is provided with sheet falling stop needles which are driven by front-and-back acting air cylinders. When the progressive die is used for punching stator sheets, the stator sheets are guided and stacked by the sheet falling guide needles, the sheet falling stop needles are driven by the front-and-back acting air cylinders to achieve stacking of a certain number of sheets, and the sheets are conveyed out of the lower die through a conveying belt, so that stacking discharging of the stator sheets is conveniently achieved, the working efficiency is improved, and the production cost is reduced.
Description
technical field [0001] The invention relates to the field of blanking dies, in particular to a progressive die for electric motor iron core punching sheet with a stack discharging mechanism. Background technique [0002] For a long time, the motor rotor and stator punches have been discharged from the progressive die, either with an elbow structure, the punches come out along the bend, and then stacked and sorted; or they are directly conveyed one by one by a conveyor belt, and then Arranged manually one by one into a stack. It is not easy to find defects if the material is discharged by the curved pipe structure, and it is easy to cause batch scrapping due to the long curved pipe; if the material is discharged by the conveyor belt, 2-3 people are needed for manual sorting, otherwise it cannot keep up with the speed of the equipment. [0003] Due to rising labor costs and rising raw material prices, the use of the original operating method for production increases the produ...
