Description
Technical field
The present invention relates to one kind to have high-precision axis hole（Or through hole）Sheet blanks blanking die, and in particular to Yi Zhongjin
Belong to sheet blanks blanking punching metal die, belong to sheet blanks molding die technology.
Background technology
Axis hole of the present invention, is all through holes with other workpiece in accurate shaft hole matching on sheet blanks.
The punching of the blanking with axis hole thin sheet of metal plate workpiece of prior art, generally use with upper mold by being connected
It is molded blanking die head and implements Punching Technology.Under its operating mode, it is present between stripper and lower die microgap cooperating face
Work metal plate workpiece, generally in non-compacted free state, plus work metal plate workpiece its into
The moment of type blanking die punching, " streaky structure " of the metallic plate materials and parts being subjected to caused by its plate calender line
Destroy, and be inevitably generated the axis hole of work metal plate workpiece and the contraction or expansion of shape, axis hole, which occurs, to be included
Deformation including roundness and diameter and metal blank workpiece shapes size etc., so that seriously affecting workpiece to be machined
Technology acuracy.
And the technology acuracy of the workpiece to be machined, it will produce direct influence for the quality of some finished products.Just
For the function motor such as stepper motor and servomotor, axis hole that its laminated stator and the mutual axis hole of lamination armature are equipped with,
In the blanking blanking process of the mould of prior art, its axis hole just often produces a variety of geometric formats and diameter and institute
Locate the change of position.In order to ensure the quality of the motor, often using the allowance for increasing laminated stator axis hole, lead to thereafter
Grinding is crossed to ensure the technical requirements of the shaft hole matching precision.
However, although the method for this " mending the fold after the sheep is lost ", caused by can overcoming the deficiency of prior art on the whole
Negative effect, but the laminated stator is made up of several thin steel monolithics riveted or bonding overlapping, and by
In the axis hole deformation for the thin steel monolithic in mould blanking blanking process, not controlled strictly each and deformation quantity size and
It is impossible consistent that its position, which becomes shifting,.This defect can not just be overcome by posterior grinding, so that the electricity
The lamination armature of machine and laminated stator part shaft hole matching gap are shown and the problem of axis hole misplaces there are not of uniform size, and direct
Affect the quality of the motor.
And the similar this negative effect caused by shaft hole matching precision is bad and axis hole misplaces, in other works
Equally existed in industry production.
The content of the invention
The present invention is intended to provide it is a kind of simple in structure, it can effectively ensure that a kind of tool of axis hole precision and blanking forming precision
There is the blanking die of the sheet blanks of high-precision axis hole, to overcome the shortcomings of prior art.
The present invention realizes the squeeze board that the technical though of its purpose is, is fixedly mounted with using the stripper with the mould, by
After on working face of the workpiece to be machined face of preceding punching axis hole with the tangible lower die of face pressure, via the positioning stem being fixedly mounted with upper mold
It is inserted into the axis hole of workpiece to be machined and carries out positioning, then the skill strategy of the shaping blank punch punching molding by being fixedly mounted with upper mold,
The die cutting accuracy of the shapes and sizes of the axis hole and its position is effectively ensured, and achieve the object of the present invention.
The present invention proposed according to above-mentioned technical though, is particularly suitable for the grading combination metal die institute of Multi-station integral
Using.
In view of above-mentioned technical though, the present invention realizes that the purport technical solution of its purpose is：
A kind of blanking die of the sheet blanks with high-precision axis hole, including upper male mould, unload with what upper male mould elasticity configured
Flitch and lower cavity die；The upper male mould, stripper and lower cavity die, according to work piece technical requirements, using common technical side
Case manufactures and mutual cooperation assembly working, and its：
There is the squeeze board with axis hole for being compacted workpiece to be machined on the working face of the stripper；And the pressure
The shape of solid plate 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 is compacted
The axis hole of plate and the positioning stem being fixedly mounted with upper male mould are slidably matched；
Under operating mode, when by the workpieces processing with axis hole input the mould and in place after, upper male mould moves downward, and with
The positioning stem that upper male mould is fixedly mounted with passes through the axis hole of squeeze board, is inserted into the axis hole of workpiece to be machined and realizes positioning, and stripper exists
Under the action of elastic component, workpiece to be machined is compacted on the working face of lower cavity die comprehensively by compression member, after by with it is convex
The workpiece to be machined blanking punching die head that mould is fixedly mounted with, implements the blanking punching to workpiece to be machined.
By technical solution given above, it can clearly understand that the present invention is real with reference to techniques discussed above conception
Its purpose to be realized is showed.
In the above-mentioned technical solutions, the present invention advocates that its described squeeze board working face is higher by the height of stripper working face,
Control is in the range of 0.05 ~ 0.10mm.But not limited to this.
And squeeze board set on the stripper, it is the compacting plate body using thickness G T.GT.GT 5mm, is embedded in the flat of stripper
It is mutually permanently connected in the blind hole of bottom existing.Given by this technical solution is the knot that squeeze board is mutually assembled with stripper
Configuration formula, but not limited to this, it can also take by stripper and the molding structure type of squeeze board overall processing.
And parallelism error≤0.05mm of the squeeze board working face and lower cavity die working face.Its purpose is obviously,
By further lifting compaction capacity of the squeeze board to workpiece to be machined, and lift the axis hole and blanking forming of workpiece to be machined
Precision.
And the workpiece to be machined, it is metal blank workpiece, and its thickness≤2mm, but not limited to this, especially metal
With metal or metal and non-metal composite board part, equally it is possible.
And the present invention is especially suitable for the continuous grading combination metal die of Multi-station integral.
Above-mentioned technical proposal is able to after implementing in full, and technical solution possessed by the present invention is reasonable, simple in structure, Neng Goubao
The features such as hindering the axis hole precision and its positional precision, and ensuring blanking die cutting accuracy, is self-evident.
