Blanking mold of motor stator punching sheet with sheet buckling groove

Abstract

The invention discloses a blanking mold of motor stator punching sheet with a sheet buckling groove. The blanking mold comprises an upper concave-convex mold and a lower concave-convex mold, wherein the middle of the upper concave-convex mold is provided with a rotor shaft hole male mold, a rotor key groove mold is arranged along the circumferential direction of the rotor shaft hole male mold, an upper concave ring is arranged around the outer side of the rotor shaft hole male mold, an upper elastic pad block is arranged in the upper concave ring, the lower side of the upper elastic pad block is connected with an upper discharging plate, the middle of the lower concave-convex mold is provided with a shaft hole in a position corresponding to the rotor shaft hole male mold, a stator excircle male mold is arranged at the excircle part of the lower concave-convex mold, a stator sheet buckling groove male mold is arranged along the inner diameter part of the stator excircle male mold, a lower concave ring is arranged around the outer side of the shaft hole, a lower elastic pad block is arranged in the lower concave ring, a lower discharging plate is connected onto the lower elastic pad block, and a sign groove male mold is also arranged on the lower concave-convex mold. Compared with the prior art, the blanking mold has the beneficial effects that the stator blanking and the processing in the buckling sheet groove can be simultaneously completed on one mold, and the work efficiency is improved.

Description

technical field [0001] The invention belongs to the field of stamping and manufacturing of motor stator punching sheets, and relates to a blanking die for motor stator punching sheets with buckle sheet grooves. Background technique [0002] With the development of science and technology, mold manufacturing is changing from the past labor-intensive and mainly relying on the manual skills of workers and the era of mechanical processing using traditional mechanical equipment to the current technology-intensive and more dependent on automation equipment, requiring high-precision The molds are matched. The traditional motor stator blanks first, and then installs the buckle groove mold on a 10-ton high-speed single-slot punching machine to punch the stator buckle groove. Generally, two people are required to operate at the same time, which is labor-intensive and difficult to produce. The efficiency is low, the repeated positioning of the punching sheet leads to the inaccurate posi...

The traditional motor stator blanks first, and then installs the buckle groove mold on a 10-ton high-speed single-slot punching machine to punch the stator buckle groove. Generally, two people are required to operate at the same time, which is labor-intensive and difficult to produce. The efficiency is low, the repeated positioning of the punching sheet leads to inaccurate punching groove position, the groove shape misalignment of the punching sheet stack and the uneven groove shape of the buckle sheet, which cannot meet the quality requirements of high-end customers
