The automatic stacking riveting technology on the stage die is to complete the original process of making the iron core(rush out of the piece-piece-riveting) in a mold, that is, to add a new stamping technology on the basis of the stage die. In addition to the requirements for the shape of the punch, such as the shaft hole and the groove hole on the rotor, the stamping positions of the rivet points required for the static and rotor iron core riveting and the counting holes for the separation of the overlapping riveting points have been added. The original loading position of the original setting and rotor is changed to the first loading function, and then each punch piece is then formed into a stacked riveting position during the stacking riveting process and the stacking counting separation process(to ensure the thickness of the core). If the core of a rotor needs to be twisted or slewing riveting, a torsion mechanism or a rotary mechanism shall be attached to the lower die of the rotor or the stator loader. This function is realized by changing or rotating the position of the overlapping riveting point on the punching plate, thus satisfying the technical requirements for automatically completing the stamping riveting and rotary riveting in a mold.
We are a design, production, sales as one of the high-tech enterprises, the best quality, welcome to purchase.

In the form of a certain geometric riveting point on the appropriate part of the fixed rotor punch piece, the upper part is a concave hole and the lower part is raised. Then, when the raised part of the upper punch piece of the same nominal size is embedded into the concave hole of the next punch piece, a "over surplus" is formed naturally in the circle where the concave die is tightened in the mold to achieve the purpose of fastening connection. In the process of forming the core in the mold, the raised part of the upper riveted point is correctly coincided with the concave hole part of the stack riveting point in the punch position. When the upper piece is affected by the drop mold pressure, The following piece generates two pieces of riveting by the reaction force generated by the friction between its shape and the concave mold wall.
In this way, through the continuous punching of high-speed automatic punch, you can get a neat iron core arranged next to a piece, the burrs are in the same direction and have a certain degree of thickness.
In order to better understand the rotor core, today to introduce to you its riveting technology, the following details.
There is still a lot to learn about the fixed rotor core. Next time, we will continue our discussion and we welcome you to come and explain. Please contact the company if you need to contact the business.
