Abstract
The utility model discloses a motor iron core die, including last stamping, die, supporter, tighten up circle and magnetic field mechanism, the die, tighten up the circle and the dress is joined in marriage on the supporter by magnetic field mechanism, the die is installed on the upper portion of supporter, the below of die sets up weak magnetic material's the circle that tightens up, the outside of tightening up the circle sets up magnetic field mechanism, is equipped with the blanking hole on the die, it can be downthehole the installing in the top of die of reciprocating of blanking to go up the stamping, the upper end internal diameter that connects towards the elastic limit adduction set hoop of piece and blanking pore pair at the iron core is less than the diameter in blanking hole. Through optimizing structure, reduce the cost of manufacture, improve production efficiency, realize better iron core closed assembly effect.
Description
Technical field
The utility model relates to motor manufacturing technology field, especially relates to motor iron core mould.
Background technology
Iron core is the core component that motor manufactures, so ensure that the quality of the iron core die of batch production is crucial.Iron core laminated press-fits integral by the punching of some, meets the requirement of electromagnetism and mechanical aspects.Core stamping closed assembly in a mold adopts the principle of snap-fastener usually, and the plane projection between punching and punching overlaps, and such closed assembly is called straight riveted joint.The common point geometry shape that laminates has V-arrangement, circle, rectangle, long arc shape etc., and punching laminates a little according to actual conditions design is some, prevents closed assembly from occurring loosening.At present, in closed assembly process, the lower punch die usually adopting oil hydraulic cylinder to drive in the below of mould exerts a force to stacked punching, and the production equipment of this employing oil hydraulic cylinder is complicated, and maintenance management inconvenience, production efficiency is low.
Utility model content
The utility model is for the deficiencies in the prior art, and technical problem to be solved is to provide a kind of motor iron core mould, and its structure is simple, and cost of manufacture is low, and iron core overlapping is effective, and production efficiency is high.
The utility model makes above-mentioned technical problem be solved by the following technical programs.
Motor iron core mould, comprise upper punch, die, supporter, tightening ring and field mechanisms, die, tightening ring and field mechanisms are fitted on supporter, die is installed in the top of supporter, the below of die arranges the tightening ring of weak magnetic material, the arranged outside field mechanisms of tightening ring, die is provided with stamping-out hole, what upper punch can move up and down in stamping-out hole is installed in above die, and the upper-end inner diameter that tightening ring docks with stamping-out hole in the elastic limit of core stamping is less than the diameter in stamping-out hole.By adopting supporter to be equipped with die, tightening ring and field mechanisms, enormously simplify press mounting structure, reducing cost of manufacture, operating simple and easy, improve production efficiency.In the elastic limit of core stamping, the upper-end inner diameter that tightening ring docks with stamping-out hole is set to the diameter being less than stamping-out hole, is convenient to tightening ring and clamps core stamping, realize better closed assembly effect.
As preferably, tightening ring is stainless steel structure.
As preferably, field mechanisms is electromagnetic coil structure.
As preferably, field mechanisms is permanent magnet structure.
As preferably, the bottom diameter of tightening ring is arranged in the elastic limit of core stamping.
As preferably, with the moving up and down to match and arrange guiding mechanism of upper punch.Further improvement, guiding mechanism comprises fairlead and guide pillar, and the bilateral symmetry of supporter arranges guide pillar, and the two ends of fairlead are slidably connected guide pillar affixed integral with upper punch.
The beneficial effects of the utility model:
1., by optimizing structure, simplify the manufacture craft of mould, reduce cost of manufacture, maintenance management is simple.
2. easy and simple to handle, be applicable to the operation of batch continuous prodution, substantially increase production efficiency.
3. by the upper-end inner diameter that tightening ring docks with stamping-out hole being set to the diameter being less than stamping-out hole in the elastic limit of core stamping, and the bottom diameter of tightening ring is arranged in the elastic limit of core stamping, advantageously in tightening ring clamping core stamping, realize better closed assembly effect.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1-upper punch, 2-die, 3-supporter, 4-tightening ring, 5-stamping-out hole, 6-core stamping, 7-fairlead, 8-guide pillar, 9-field mechanisms.
Detailed description of the invention
Also by reference to the accompanying drawings the utility model is described in detail below by embodiment.
The utility model motor iron core mould as shown in Figure 1, comprises upper punch 1, die 2, supporter 3, tightening ring 4 and field mechanisms 9.Die 2, tightening ring 4 and field mechanisms are fitted on supporter 3, die 2 is installed in the top of supporter 3, the below of die 2 arranges the tightening ring 4 of weak magnetic material, the arranged outside field mechanisms 9 of tightening ring 4, can select to adopt the tightening ring 4 of stainless steel to reduce bypass magnetic force, field mechanisms 9 can be set to solenoid or permanent magnet according to actual conditions.Die 2 is provided with stamping-out hole 5, and what upper punch 1 can move up and down in stamping-out hole 5 is installed in above die 2.In order to better clamp core stamping 6, in the elastic limit of core stamping 6, the upper-end inner diameter that tightening ring 4 docks with stamping-out hole 5 is set to the diameter being less than stamping-out hole 5, further, can further the bottom diameter of tightening ring 4 be also arranged in the elastic limit of core stamping 6.In order to the die-cut operation of auxiliary upper trimming die 1, can be upper punch 1 and guiding mechanism is set.As a kind of embodiment, guiding mechanism comprises fairlead 7 and guide pillar 8, and the bilateral symmetry of supporter 3 arranges guide pillar 8, and the two ends of fairlead 7 are slidably connected guide pillar 8 affixed integral with upper punch 1.
The utility model is not limited to above-described embodiment, upper punch, die, supporter, the embodiment of other malformation that equivalence is replaced in the middle of the known technology that the contour structures of tightening ring and field mechanisms and connected mode each other also can adopt those skilled in the art to obtain or prior art, as long as belong to technical conceive of the present utility model or spirit, die is equipped with by adopting supporter, tightening ring and field mechanisms simplify press mounting structure, and by the upper-end inner diameter that tightening ring docks with stamping-out hole being set to the diameter being less than stamping-out hole in the elastic limit of core stamping, to be conducive to tightening ring clamping core stamping, the embodiment realized for the purpose of better closed assembly effect all drops in protection domain of the present utility model.
