Abstract
The utility model discloses a kind of sheet blanks high accuracy axis hole die cutting die, the stripper configured including upper male mould and upper male mould elasticity and lower cavity die, with it on the work surface of stripper, having the squeeze board for being compacted workpiece to be machined is principal character, and under operating mode, workpiece to be machined is punched axis hole under conditions of squeeze board is compacted with face with recessed die face, there is technical scheme reasonable, simple in construction, axis hole die cutting accuracy high, it is particularly well-suited to the production of the die-cut axis hole of motor lamination stator.
Description
Technical field
This utility model relates to a kind of sheet blanks high accuracy axis hole die cutting die, is specifically related to the metallic plate materials and parts high accuracy die-cut metal die of axis hole, belongs to sheet blanks mould technology.
Background technology
The die cutting die of the sheet blanks axis hole of the sheet blanks axis hole of prior art especially diameter ＞ φ 10mm, under its operating mode, it is present in the work metal plate workpiece of (microgap coordinates) between stripper with lower cavity die cooperating face, generally individually it is in the free state of non-compacted, plus work metal plate workpiece die-cut instantaneous of its axis hole drift, the destruction of the metal sheet suffered " streaky structure " formed in its sheet material calender line, and it is inevitably generated the expansion including roundness and diameter etc. of the work metal plate workpiece axis hole or contraction distortion, so that having a strong impact on the axis hole technology acuracy of workpiece to be machined.
And the technology acuracy of described workpiece to be machined, quality for finished product will produce directly impact, for with the function motor such as motor and servomotor, the axis hole that the axis hole mutual with lamination armature of its laminated stator is equipped, in the axis hole blanking process of the mould of prior art, its axis hole the most often produces the change of multiple geometry and diameter.In order to ensure the quality of described motor, often use and strengthen laminated stator axis hole and the allowance of lamination armature cylindrical, ensured the precision techniques requirement of described shaft hole matching 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 is caused can be overcome on the whole, but described laminated stator is consisted of riveted or bonding overlapping numerous thin steel monolithics, and due in mould blanking process, the deformation of the thin steel monolithic axis hole strictly not controlled described in each and variable size are impossible consistent, this defect just cannot be overcome by posterior grinding, so that the problem that the shaft hole matching gap, local of the lamination armature of described motor and laminated stator exists cause not of uniform size, and directly affect the quality of described motor.
And similar this due to axis hole local bad the caused negative effect of quality of fit, equally exist in other industrial products produce.
Summary of the invention
This utility model aims to provide a kind of simple in construction, it can be ensured that a kind of sheet blanks high accuracy axis hole die cutting die of axis hole die cutting accuracy, to overcome the deficiency of prior art.
This utility model realizes the technical though of its purpose, use the squeeze board that the stripper with described mould is fixedly mounted with, after processed plate workpiece face is compacted on the work surface of lower cavity die with face, again by the axis hole drift being fixedly mounted with upper male mould, the technical tactic of the axis hole of die-cut processed plate workpiece, resist axis hole produced expansion or contraction in blanking process, it is ensured that the precision of the die-cut shape size of described axis hole, it is achieved the purpose of this utility model.
This utility model proposed according to above-mentioned technical though, is particularly suitable for Multi-station integral combination metal die and is used.
Because above-mentioned technical though, this utility model realizes the purport technical scheme of its purpose and is:
A kind of sheet blanks high accuracy axis hole die cutting die, 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 workpiece to be machined technology requirement, use common technical scheme manufacture and the assembly working that cooperates, and its:
The work surface of described stripper has the squeeze board with through hole for being compacted workpiece to be machined；And the described shape size of squeeze board matches with the shape size of workpiece to be machined, and the through hole of squeeze board and the axis hole drift being fixedly mounted with upper male mould are slidably matched；
Under operating mode, after workpiece to be machined inputs described mould and puts in place, upper male mould moves downward, stripper is under the effect of elastic component, workpiece to be machined is compacted on the work surface of lower cavity die comprehensively by squeeze board front, by the axis hole drift being fixedly mounted with upper male mould after, passing through the through hole of squeeze board, that implements workpiece to be machined axis hole is die-cut.
By technical scheme given above, conceive it is understood that this utility model achieves its purpose to be realized in conjunction with techniques discussed above.
In technique scheme, this utility model advocates that its described squeeze board work surface exceeds the height of upper male mould work surface, controls in the range of 0.05 ~ 0.10mm.
Described plate workpiece to be machined is metal blank workpiece, and its thickness≤2mm.But being not limited to this, especially metal and metal or metal and non-metal composite board part, equally applicable.
And this utility model is advocated especially, squeeze board set on described stripper, is the compacting plate body using ＞ 5mm, and be mutually permanently connected in being embedded in the flat blind hole of stripper existence.The version that to be squeeze board mutually assemble 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 this utility model is also advocated, described squeeze board work surface and the parallelism error≤0.05mm of lower cavity die work surface.Its purpose is obviously, by promoting the squeeze board compaction capacity to processed plate workpiece further, to promote the die cutting accuracy of described axis hole.
And this utility model is particularly useful for making the continuous grading combination metal die of Multi-station integral of motor lamination armature stator.
After technique scheme is implemented in full, the technical scheme that this utility model is had is reasonable, and simple in construction, it can be ensured that the features such as described axis hole die cutting accuracy is apparent from.
Accompanying drawing explanation
Fig. 1 is the three-dimensional simple schematic diagram of a kind of processed plate workpiece of this utility model；
Fig. 2 is the structure schematic diagram of a kind of detailed description of the invention of this utility model, and shown in figure, 6 are fixedly mounted with plate for upper mold, and 7 are fixedly mounted with plate for lower mold.
Detailed description of the invention
Hereinafter compareing accompanying drawing, by the description of detailed description of the invention, be described specifically this utility model, but be not limited to this, other uses the technical scheme that this utility model technical though is proposed, and belongs to protection domain of the present utility model.
