Abstract
The invention discloses a blanking die for a sheet part with a high-precision axle hole. The blanking die comprises an upper male die body, a discharging plate and a lower female die, wherein the discharging plate is in elastic fit with the upper male die body; the blanking die is mainly characterized in that a compacting plate used for compacting a to-be-machined workpiece is arranged on a working surface of the discharging plate. Under the working conditions of being compacted in a surface-surface manner by the compacting plate and the lower female die and being positioned by a positioning core rod, the to-be-machined workpiece with the axle hole is punched and blanked to be formed. The blanking die has the characteristics that the technical scheme is reasonable, the structure is simple, the precision of the axle hole and the precision of the position of the axle hole are high, the punching and blanking forming precision is high, and the like; the blanking die is particularly applicable to punching forming production of laminated stators of motors.
Description
Technical field
The present invention relates to the blanking die that one has the sheet blanks of high accuracy axis hole (or through hole), be specifically related to a kind of metallic plate die-cut metal die of materials and parts blanking, belong to sheet blanks mould technology.
Background technology
Axis hole of the present invention, is all of through hole with other workpiece in accurate shaft hole matching on sheet blanks.
The blanking with axis hole thin sheet of metal plate workpiece of prior art is die-cut, and generally adopting is implemented Punching Technology by the molding blanking die head being connected with upper mould.Under its operating mode, it is present in the work metal plate workpiece between stripper and cooperating face, counterdie microgap, the generally individually free state being in non-compacted, plus work metal plate workpiece in its molding blanking die die-cut moment, the destruction of " streaky structure " that the metallic plate materials and parts suffered cause in its sheet material calender line, and it is inevitably generated the axis hole of work metal plate workpiece and the contraction of profile or expansion, axis hole is occurred to include the deformation of roundness and diameter and metal blank workpiece shapes size etc., so that having a strong impact on the technology acuracy of workpiece to be machined.
And the technology acuracy of described workpiece to be machined, the quality for some finished product will produce direct impact.With regard to for the function motor such as motor and servomotor, the axis hole that its laminated stator is equipped with the mutual axis hole of lamination armature, in the blanking blanking process of the mould of prior art, its axis hole just often produces the change of multiple geometric format and diameter and present position.In order to ensure the quality of described motor, often adopt the allowance strengthening laminated stator axis hole, ensured the technology requirement of described shaft hole matching precision thereafter by grinding.
But, the way of this although " mending the fold after the sheep is lost ", the negative effect that the deficiency of prior art causes can be overcome on the whole, but described laminated stator is consisted of riveted or bonding overlapping several thin steel monolithics, and owing to, in mould blanking blanking process, it is impossible consistent that the axis hole deformation of each described thin steel monolithic strictly not controlled and deformation quantity size and position thereof become shifting.This defect just cannot be overcome by posterior grinding, so that shaft hole matching gap, the lamination armature of described motor and laminated stator local exists not of uniform size showing and the problem of axis hole dislocation, and directly affects the quality of described motor.
And similar this due to the negative effect that shaft hole matching precision is bad and axis hole dislocation causes, equally exist in other industrial products produce.
Summary of the invention
It is desirable to provide a kind of simple in construction, it is possible to it is effectively ensured the blanking die of a kind of sheet blanks with high accuracy axis hole of axis hole precision and blanking forming precision, to overcome the deficiency of prior art.
The present invention realizes the technical though of its purpose, adopt the squeeze board that the stripper with described mould is fixedly mounted with, by after the workpiece to be machined face of front die-cut axis hole and face compacting are on the work surface of counterdie, insert the axis hole of workpiece to be machined via the location stem stem being fixedly mounted with upper mould and carry out location, again by the skill strategy of the molding blank punch punching molding being fixedly mounted with upper mould, it is effectively ensured the shape of described axis hole and the die cutting accuracy of size and position thereof, and realizes the purpose of the present invention.
According to the present invention that above-mentioned technical though is proposed, it is particularly suitable for the grading combination metal die of Multi-station integral and is adopted.
Because above-mentioned technical though, the present invention realizes the purport technical scheme of its purpose and is:
The blanking die of a kind of sheet blanks with high accuracy axis hole, the stripper configured including upper male mould and upper male mould elasticity and lower cavity die；Described upper male mould, stripper and lower cavity die, according to work piece technology requirement, adopt common technical scheme manufacture and the assembly working that cooperates, and its:
The work surface of described stripper has the squeeze board with axis hole for compacting workpiece to be machined；And the described shape of squeeze board matches with the shape of workpiece to be machined, and the size of squeeze board is less than the size of workpiece to be machined, and the axis hole of squeeze board and the location stem stem being fixedly mounted with upper male mould are slidably matched；
Under operating mode, after being inputted described mould by the processing work with axis hole and put in place, upper male mould moves downward, and the location stem stem being fixedly mounted with upper male mould passes through the axis hole of squeeze board, insert workpiece to be machined axis hole in realize location, stripper under the effect of elastic component, by compression member by comprehensive for workpiece to be machined compacting on the work surface of lower cavity die, after by the workpiece to be machined blank punch head being fixedly mounted with upper male mould, implement the blanking of workpiece to be machined is die-cut.
By technical scheme given above, can clearly understand in conjunction with techniques discussed above conception, present invention achieves its purpose to realize.
In technique scheme, the present invention advocates that its described squeeze board work surface exceeds the height of stripper work surface, controls within the scope of 0.05 ~ 0.10mm.But it is not limited to this.
And squeeze board set on described stripper, it is the compacting plate body adopting thickness G reatT.GreaT.GT 5mm, is embedded in the flat blind hole of stripper to be mutually permanently connected and exists.The version that to be squeeze board assemble mutually with stripper given by this technical scheme, but it is not limited to this, it is also possible to take by the version of stripper Yu squeeze board overall processing molding.
And the parallelism error≤0.05mm of described squeeze board work surface and lower cavity die work surface.Its purpose is obviously in that, by promoting the squeeze board compaction capacity to workpiece to be machined further, and promotes the axis hole of workpiece to be machined and the precision of blanking forming.
And described workpiece to be machined, it is metal blank workpiece, and its thickness≤2mm, but is not limited to this, especially metal and metal or metal and non-metal composite board part, be possible equally.
And the present invention is especially suitable for the continuous grading combination metal die of Multi-station integral.
After technique scheme is implemented in full, the technical scheme that the present invention has is reasonable, simple in construction, it is possible to ensure described axis hole precision and positional precision thereof, and guarantee the features such as blanking die cutting accuracy, be self-evident.
