Abstract
The utility model discloses an electric motor stator core punching die. The electric motor stator core punching die comprises an upper die holder, a lower die holder and a die handle. A guide pillar is fixedly connected to the lower die holder. A guide sleeve is fixedly connected to the upper die holder. The guide sleeve is connected with the guide pillar in a sleeved mode. A movable hitting rod is connected with the middle of the die handle in a sleeved mode. The lower end of the hitting rod is fixedly connected with a push plate. A concave-convex die and a blanking female die are fixedly arranged on the lower die holder. A punching male die is arranged at the lower end of the upper die holder. A discharge plate is arranged on the lower die holder. Elastic rubber blocks are arranged at the two ends of the discharge plate. Discharge screws are arranged between the elastic rubber blocks and the discharge plate. A material pushing block is arranged on one side of the concave-convex die. A push rod is arranged on the material pushing block. Elastic and automatic discharge is adopted for the electric motor stator core punching die, compared with manual discharge, rubber serves as a discharge element for an elastic discharge device, the discharge force is small, the quality is good, and the straightness is high. Thus, the product quality of electric motor stator cores is improved.
Description
Technical field
The utility model relates to a kind of diel, is specifically related to a kind of stator core in motor punch die.
Background technology
Punching press, is at room temperature to utilize the mould being arranged on forcing press to exert pressure to material, makes it produce separation or plastic deformation, thereby obtains a kind of pressure processing method of required part.Diel is the requisite technological equipment of punching production, is technology-intensive product, and it can carry out the processing and forming such as punching, blanking, bending and drawing.Quality, production efficiency and the production cost etc. of stamping parts have direct relation with Design of Dies and manufacture.And stator core in motor is by the silicon steel sheet concentric circles forming that superposes, its required precision is quite high, because the quality of its silicon steel sheet punching press size quality directly affects the quality of motor, and its quality and size are to be ensured by the quality of mould completely, general press machine, because motor stator punching quality is relatively light, therefore mostly adopt the manual blowing of staff and discharging to complete the punching press of stator core, but because silicon steel sheet is more frivolous, therefore in the process of staff's discharging, very easily there is overexertion and produce slight deformation, thereby finally affect the Forming Quality of stator core.
Utility model content
Technical problem to be solved in the utility model is for above-mentioned the deficiencies in the prior art, and a kind of energy automatic discharging is provided, and the less stator core in motor punch die of stripping force, makes stator core gained quality better, and glacing flatness is higher.
The technical scheme that the utility model adopts is: a kind of stator core in motor punch die, comprise upper bolster, die shoe and die shank, on described die shoe, be fixedly connected with guide pillar, on described upper bolster, be fixedly connected with guide pin bushing, described guide pin bushing socket guide pillar, described die shank intermediate sleeve is connected to the movable bar of beating, beat bar lower end and be fixedly connected with push pedal, on described die shoe, be fixedly installed respectively concave-convex mold and blanking die, described upper bolster lower end is provided with piercing punch, on described die shoe, be provided with stripper, described stripper two ends are provided with elastic block rubber, between described elastic block rubber and stripper, be provided with unloading bolt, described concave-convex mold one side is provided with expeller, on described expeller, be provided with push rod.
On described die shoe, be provided with pin stop.
