Automatic bonding and stamping die in stator and rotor core dies

Abstract

The invention relates to the technical field of stamping dies, in particular to an automatic bonding and stamping die in stator and rotor core dies. The shortcomings in the prior art are overcome, andthe automatic adhesive stamping die comprises a base; a lower die, guide pillars arranged symmetrically, and fixing plates arranged symmetrically are fixed to the top of the base by bolts separately;a top plate is fixedly installed on the tops of the guide pillars, and a lift pressing plate is slidably arranged at the exteriors of the guide pillars; after completion of stamping and bonding treatment through inner workpieces, the pressure held by a second pressure sensor is reduced due to coating melting, and fed back to the interior of a discharging cylinder through pressure reduction signals, so that the discharging cylinder acts once to pull a discharge sliding seat to slide toward the both sides in a side groove; thus, a product falls down through a material falling slot automatically, and automatic discharge is achieved; bonding treatment is finished in the die through the stamping die, so that the stamping die does not need to be placed in heating equipment for processing; and alarge amount of operation time and manpower are saved, and the production efficiency is high.

Description

technical field [0001] The invention relates to the technical field of stamping dies, in particular to a stamping die for automatic bonding in a stator-rotor iron core die. Background technique [0002] Stamping is a forming processing method that applies external force to plates, strips, pipes and profiles by presses and molds to cause plastic deformation or separation to obtain workpieces (stamping parts) of required shape and size. The die used for stamping is called stamping die. [0003] The stamping dies used for stator and rotor cores in the prior art have the following defects: 1. The positioning accuracy of the mold is low, resulting in low machining accuracy; The iron loss of the stator and rotor core prepared by this process is relatively large, which reduces the performance of the motor; 3. After the stamping is completed, it needs to be manually taken out and put into the heating equipment for secondary treatment, and the work efficiency is low. Contents of t...
