Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides a stepper motor gear and its one-time fine-cutting die, which solves the problem that the existing fine-cutting dies for the production of stepper motor gears in the above-mentioned background technology often fail after fine-cutting. The tangent surface of the stepping motor gear is warped and uneven, resulting in unqualified quality of the stepping motor gear, and the flatness of the stainless steel sheet cannot be tested in advance, which may easily lead to insufficient flatness of the stepping motor gear after cutting. unusable problem

Abstract

The invention discloses a stepping motor gear and a one-time precision cutting die thereof, and relates to the technical field of stepping motor gear machining. The stepping motor gear comprises a stepping motor gear body and the one-time precision cutting die; the one-time precision cutting die comprises a machining support and a pressure plate, the machining support is used for placing a to-be-machined stainless steel plate material; the pressure plate is fixedly arranged at the bottom end of a hydraulic cylinder; a one-time precision cutting structure comprises a pre-pressing cylinder piece, a first supporting rod, and a second supporting rod, the bottom end of the second supporting rod is fixedly connected with an inner circle fine cutting piece through a bolt. According to the stepping motor gear and the one-time precision cutting die thereof, the flatness of the surface of a stainless steel plate can be detected before precision cutting, the uneven surface of the stainless steel plate is prevented from being machined, the surface of the stainless steel plate is pressed and clamped during precision cutting, and the condition that the finish-cut part on the surface of the stainless steel plate is tilted or the finish-cut surface is not flat is avoided, so that the quality of the machined stepping motor gear is improved.

Description

technical field [0001] The invention relates to the technical field of stepping motor gear processing, in particular to a stepping motor gear and a disposable fine-cutting mold thereof. Background technique [0002] A stainless steel gear-shaped part with a thickness of 0.6mm, which is especially suitable for stepping motors of low-voltage electrical switches. The name of this part is the stepping motor gear. One drop is performed to fine cut the stainless steel raw material to obtain the stepper motor gear. [0003] Existing fine-cutting molds for producing stepper motor gears tend to cause warping and unevenness on the cut surface of the stepper motor gear after fine cutting, resulting in unqualified quality of the stepper motor gear, and it is impossible to pre-smooth the stainless steel sheet. It is easy to make the stepping motor gears after cutting have insufficient flatness and make them unusable. Contents of the invention [0004] Aiming at the deficiencies of th...
