Abstract

The utility model relates to the technical field of motor element processing in the mechanism field, in particular to torque motor stator punching mould. In the torque motor stator punching mould, a lower mould holder is provided with a lower mould;, the lower mould holder and the lower mould are fixed and located through a pin screw; the lower mould is internally provided with a material support plate which supports up a punching sheet, therefore the stator punching sheet is always smooth when being cut to circular; the material support plate is contacted with a spring in the lower mould which is sheathed on a screw plug; mould handle is arranged on an upper mould holder and the mould handle is positioned with a punching machine; the upper mould holder is provided with four screws, while the other one end of each screw is fixed in a stripping plate; a rectangular spring is sheathed on the screw and generates stable stripping force; a base plate and a punch fixing plate are fixed in sequence under the upper mould holder through screws; and a fixing groove punch in the punch fixing plate is tangent with an inner circular punch. The torque motor stator punching mould has the advantages of simple structure, high feasibility and low manufacture cost.

Description

Torque motor stator punching mould

Technical field

The utility model relates to the motor part processing technical field of mechanical field, concretely, relates to torque motor stator punching mould.

Background technology

How few in batches in torque motor stator punching specification, produce with compound press tool in the process, progressive die mould design difficulty is big, manufacturing process is complicated and the cycle long and because its yoke is narrow especially, feeding difficulty especially; Therefore use feasibility low, shortcomings such as manufacturing cost height.

Summary of the invention

In order to overcome above-mentioned deficiency, the purpose of this utility model is to provide a kind of torque motor stator punching one-shot mould, it is used for making motor stamping, and the characteristics of torque motor stator punching mould are to cut circle in the stator in the time of can processing inner stator punching stator slot synchronously.

The utility model by die shoe, counterdie, lining, packing ring, screw, guide pillar, spring, guide pin bushing, guide pin bushing frame, back-up ring, screw, nut, upper bolster, rectangle spring, screw, screw, screw, limited post, die shank, groove drift, backing plate, drift fixed head, stripper plate, screw, pin, screw, sell, cut interior round punch, retainer plate, plug screw, spring and form; Counterdie is installed on the die shoe, die shoe and counterdie are fixed by the pin screw and are located, retainer plate is arranged in the counterdie, retainer plate holds up punching, making stator punching is smooth all the time when cutting the garden, spring in the retainer plate contact die shoe, spring housing has a die shank above the upper bolster on plug screw, die shank and punch press location, upper bolster has four screws, and the screw other end is fixed in the stripper plate, and the rectangle spring housing is on screw, the rectangle spring produces the material power of steadily taking off, be backing plate and drift fixed head successively below upper bolster, backing plate and drift fixed head rely on screw be fixed on upper bolster below, the holddown groove drift is cut interior round punch in the drift fixed head.

The utility model advantage: simple in structure, feasibility is high, low cost of manufacture.
