[0004] However, the structure of the compound punching die required by the compound punching method is complex and the production cycle is too long. In order to ensure the production level, a large amount of money needs to be invested in the production of the mold, which makes the product development cycle longer and increases the production cost of the punching sheet.

Abstract
The invention discloses a punched plate manufacturing device. The punched plate manufacturing device comprises a punch and a die holder. The punch is connected with a punched plate manufacturing device body part, the lower portion of the punch is provided with a cutting edge used for punching a punched plate to be machined downwards, and the punch is further provided with a guide protrusion opposite to the cutting edge. The die holder is used for fixing the punched plate and provided with a groove located below the punch, and one side wall of the groove is arranged on one side of the outer side wall of the guide protrusion so as to prevent the punch from deviating away from the cutting edge in downward punching. According to the device, in the pressing punching process of the punch, the guide protrusion abuts against the side wall so as to prevent the punch from moving away from the cutting edge in downward punching, so that deviation of the cutting edge in pressing of the punch is avoided, punching accuracy of the cutting edge is guaranteed, the situation that the punch collides with other components due to deviation and is damaged is avoided, the service life of the device is guaranteed while the production cycle is shortened, and the use cost is lowered.
Description
technical field [0001] The invention relates to the technical field of engineering machinery, in particular to a punching device. Background technique [0002] With the development of modern technology, the performance requirements for motors are also increasing, and correspondingly, the production requirements for motors are also increasing. [0003] At present, the production of traction motor punching is usually only a single structural parameter change, that is, the change of the outer diameter of the punching sheet, and considering the punching size and other reasons, the production usually adopts the re-punching method. [0004] However, the structure of the compound punching die required by the compound punching method is complex and the production cycle is too long. In order to ensure the production level, a large amount of money needs to be invested in the production of the mold, which makes the product development cycle longer and increases the production cost of t...
