Abstract
The utility model relates to a stamping male die for preventing a motor stamping piece from generating a wave shape. The stamping male die comprises a male die body and is characterized in that a protruded strip is arranged in the middle of the surface of one side of the male die body and extends from the top of the male die body to the bottom of the male die body. The center line of the protruded strip and the center line of the male die body coincide. The thickness of the protruded strip is 0.2-0.25mm, and the width of the protruded strip is no smaller than 3mm. The stamping male die solves the problem of the wave shape of the motor stamping piece, a stamping process is suitable for a large motor single groove notching, the wave shape of the stamping piece generated in the stamping process can be eliminated, and the stamping male die has the advantages of being convenient to operate, wide in applied range and good in effect; besides, the stamping male die has the advantages of being simple in structure, convenient to operate and use and long in service life.
Description
Technical field
The utility model relates to a kind of for processing the punch of motor stamping, and especially a kind of motor stamping of avoiding produces corrugated punching press punch.
Background technology
In prior art, the punching punching of motor mainly adopts the punching of single groove and rushes again two kinds of modes, for the motor below H315, substantially take multiple punching as main, and more than H355 motor mainly be take single groove punching as main.The problem existing in the process of single groove punching is that after punch punching, the groove of punching and the position between groove can form and arch upward, and cause punching sheet surface uneven, undulate.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of motor stamping of avoiding to produce corrugated punching press punch, can eliminate in motor stamping punching process and produce corrugated phenomenon.
The technical scheme providing according to the utility model, a kind of motor stamping of avoiding produces corrugated punching press punch, comprise punch body, feature is: the middle part at a side surface of described punch body arranges raised line, and this raised line is extended to the bottom of punch body by the top of punch body.
The center line of described raised line overlaps with the center line of punch body.
The thickness of described raised line is 0.2～0.25mm.
The width of described raised line is not less than 3mm.
The utility model solves motor stamping waveform Sheet Metal Forming Technology and is applicable to large motor single groove-punching groove, can eliminate the corrugated phenomenon that punching produces in punching process, has the advantages such as easy to operate, applied widely, effective; And the utlity model has the advantages such as simple in structure, operation, easy to use, die life length.
Accompanying drawing explanation
Fig. 1 is the schematic diagram that in prior art, single groove rushes punch.
Fig. 2 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with concrete accompanying drawing, the utility model is described in further detail.
As shown in Figure 1 and Figure 2: the utility model rushes at existing single groove on the basis of punch and processes, bilateral symmetry at punch body 1 one side surfaces grinds off 0.2～0.25mm, middle part at punch body 1 side surface forms raised line 2, the thickness of this raised line 2 is 0.2～0.25mm, and the width of raised line 2 is not less than 3mm.
When employing punch as shown in Figure 2 carries out punching punching, first raised line 2 contacts with punching material, the raised line 2 that is positioned at punch body 1 middle part liquidates after sheet material stretches, punch body 1 contacts with punching material again, through test of many times, punching punching out can be avoided the phenomenon arching upward between the groove of punching and groove completely like this.
The utility model is applicable to the above large motor single groove-punching groove of H355, solve the punching in punching process of conventional punch die and produced corrugated drawback, guarantee large quality of rotor of motor, reduced large motor because of vibration and axial float that punching wave causes, improved the stability of large motor operation.
