Detailed Description

The present invention will be further described with reference to fig. 1 to 4.

The utility model relates to a punching machine, it includes punching a hole platform 11, a plurality of punching press subassembly 14, and reference column 12 has been arranged at the mesa middle part of punching a hole platform 11, and when placing the stator, reference column 12 passes the middle part of stator. The side of reference column 12 is formed with the location arch, and the location arch is bar structure, and one of them stator yoke of stator shaping has the cell body structure, through the protruding cooperation of cell body structure and location, can confirm the stator in the position of platform 11 that punches a hole.

Some examples of the present invention will be described below, and the following work is a stator.

The first embodiment is as follows:

a plurality of first bulges 13 for punching are arranged on the table surface of the punching table 11, the first bulges 13 are distributed around the positioning columns 12, the punching assemblies 14 are distributed around the punching table 11, and the punching assemblies 14 are uniformly distributed along the circumference. The first bulge 13 is abutted against the waste sheet, and the punching component 14 presses the workpiece downwards, so that the connecting ribs reserved between the waste sheet and the scattered sheet are cut off.

Each first bump 13 is mounted on the top of the punching table 11 through a supporting column 18, and the top end of the supporting column 18 is used for supporting the workpiece to suspend the workpiece, so that the stator position deviation caused by the debris particles on the punching table 11 is avoided.

The punching assembly 14 comprises a lifting column 15 and a punching part 16 for pressing the top of the work piece, and the punching table 11 is arranged with a plurality of mounting seats 17 for mounting the lifting column 15. The ram 16 extends or retracts on the side of the top of the lifting column 15, and the actions of the lifting column 15 and ram 16 are pneumatically driven. The punching part 16 is retracted on the side of the top of the lifting column 15, so that the workpiece can be conveniently placed on the punching table 11, the punching part 16 is extended again, and the lifting part moves downwards, so that the punching part 16 presses the upper side of the workpiece.

Example two:

the difference between this embodiment and the first embodiment is that the first protrusion 13 can be lifted and lowered, and the action of the first protrusion 13 is driven by pneumatic means. The punching part 16 presses the upper side of the workpiece to fix the workpiece, and the first bulge 13 rises to punch and cut off the connecting rib reserved by the waste sheet.

Before the first bulge 13 is lifted, the top end of the supporting column 18 supports the workpiece, so that the workpiece is suspended, the situation that the position of the stator is deviated due to the debris particles on the punching platform 11 is avoided, and the punching is not influenced.

Example three:

the table surface of the punching table 11 is provided with a plurality of supporting parts for supporting workpieces, each supporting part surrounds the positioning columns 12 and is distributed, each punching assembly surrounds the punching table 11 and is uniformly distributed along the circumference, each punching assembly comprises a lifting column 15 and a punching part for punching, and a second protrusion for punching is arranged on the lower side of the front end of each punching part. The blanking portion extends or retracts from the side of the top of the lifting column 15 and the action of the lifting column 15 and blanking portion is pneumatically driven.

The position of the lower side surface of the workpiece supported by the supporting part is other positions except the position of the waste sheet, so that the waste sheet automatically falls down after the punching assembly punches the connecting rib reserved by the waste sheet. The side of die-cut portion at lifting column 15 top is retracted, makes things convenient for the stator to place at punching table 11, and die-cut portion stretches out again, and lifting column 15 moves down, thereby the second is protruding to the die-cut splice bar that will reserve of waste sheet cut off.

In addition, the supporting part enables the workpiece to be suspended, and the situation that the placement of the stator is influenced by the debris particles on the punching platform 11 can be avoided.

Example four:

the difference between this embodiment and the third embodiment is that the second protrusion can be lifted and the action of the second protrusion is driven pneumatically. After the punching part presses the upper side of the workpiece, the second bulge extends downwards to punch the waste sheet.

The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present invention within the knowledge of those skilled in the art.
