Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-3, the present invention provides a technical solution: the utility model provides a motor housing punching die, including base station 1, collateral branch fagging 2, cylinder 4, stripper plate 5, stripper plate 7 and splint 8, the welding of one side center department of base station 1 has collateral branch fagging 2, be used for supporting fixed cylinder 4, and the inboard welding in top of collateral branch fagging 2 has hanger plate 3, the top below of hanger plate 3 is fixed with cylinder 4, be used for exerting pressure, fixedly connected with stripper plate 5 is served in stretching out of cylinder 4, be used for the extrusion to punch a hole, under stripper plate 5, and be located base station 1 and be fixed with stripper plate 7, be used for punching a hole, the both sides of stripper plate 7 all are provided with splint 8, be used for fixed motor housing.

Furthermore, a punching groove 9 is formed in the center and the edge of the punching template 7, a leak hole 10 is formed right below the punching groove 9 and on the base platform 1, and the punching head 6 can conveniently stretch into the punching hole.

Furthermore, the diameter of the extrusion plate 5 is slightly smaller than that of the punching template 7, the punching head 6 is welded at the bottom of the extrusion plate 5 and is positioned right above the punching groove 9, the diameter of the punching head 6 is the same as that of the corresponding punching groove 9, so that the extrusion punching is facilitated, and the redundant pore plates are ejected out.

Further, splint 8 is the arc, and its bottom is fixed in on base station 1, and splint 8's material is rubber, possesses certain elasticity and plasticity, is convenient for extrude fixedly.

Further, the base station 1 is provided with a controller 11, and the controller 11 is electrically connected with the cylinder 4, so that the operation and control are facilitated.

Further, two supporting legs 12 are welded at the bottom of the base 1 for supporting and fixing.

In the embodiment, the motor shell punching die is operated as follows:

the method comprises the following steps: the two clamping plates 8 are pulled outwards, the tops of the two clamping plates are slightly deformed and outwards expanded by using the elasticity and plasticity of the two clamping plates 8, and then the end of the motor shell needing to be punched is placed on the punching template 7 between the two clamping plates 8.

Step two: the clamping plate 8 is loosened, the clamping plate is automatically reset by utilizing the elasticity of the clamping plate, then the air cylinder 4 is started through the controller 11, the extrusion plate 5 is driven to descend, the punching head 6 is extruded on the motor shell along with the descending of the extrusion plate 5, when high-strength pressure is applied, the punching head 6 extrudes a rotating shaft extending hole and a heat dissipation hole in the motor shell, and the extruded hole piece falls down through the leakage hole 10.

Step three: after the completion punches a hole, the lift cylinder 4 takes the punching head 6 to rise, breaks away from the groove 9 that punches a hole, then holds motor housing to rotatory slightly, pick up the ram, penetrate from the small opening 10, and upwards the top moves, thereby with motor housing ejecting, accurate punching a hole, the precision is high, and is fast, improves machining efficiency greatly, it needs to explain that the motor housing that will punch a hole is small motor housing, for example small motor, micro motor etc..
