Abstract

The invention relates to the technical field of fan-shaped slices, and discloses a fan-shaped slice one die double punch device and a double punch technology thereof. The double punch device comprisesa main body, wherein the inner wall of the bottom of the main body is provided with a grooved plate, the inner part of the grooved plate is provided with a material leakage port, and the top of the grooved plate is provided with a fan-shaped slice. According to the fan-shaped slice one die double punch device and the double punch technology thereof, a strong pressure air cylinder, a punching plate and punching heads are arranged and the relation between the strong pressure air cylinder, the punching plate and the punching heads is exist, when the strong pressure air cylinder is started, a hydraulic rod at the bottom of the strong pressure air cylinder moves and drives the punching plate to move downward, with the movement of the punching plate, the punching heads contact the fan-shaped slice and the simultaneously punching operation of the two punching heads is carried out for the fan-shaped slice, in the process of punching, the bottom of the punching plate can contact with the top of the fan-shaped slice, at this time, limiting plates at both ends of the punching plate contact with the two ends of the fan-shaped slice, and plays a fixing and limiting role on the fan-shaped slice, so that the fan-shaped slice rom shaking in the process of punching is prevented, the punching effect is better, the working efficiency of punching is effectively improved and the practicability ofthe device is improved.

Description

Technical field [0001] The invention relates to the technical field of fan-shaped sheets, in particular to a fan-shaped sheet one-die double punching device and a double punching process. Background technique [0002] Segments are precision parts that work with high-speed rotating parts such as motor rotors. Stamping relies on presses and molds to apply external force to plates, strips, pipes and profiles to produce plastic deformation or separation, thereby obtaining the desired shape and The forming method of the size of the workpiece (pressing part). The stator and rotor are important core components of generators and motors. The stator segment and rotor segment are the main components of the stator core and the rotor core. The material of the stator segment segment is generally cold-rolled silicon steel sheet. The punching process And the mold structure is the key to ensure the quality of the punch. [0003] However, the existing stamping device is only provided with a stampi...
