Abstract
The utility model relates to a steel ball cold -heading mould improves structure, including die block mold core and die mold core, die block mold core and die mold core all adopt the wolfram steel material to make, the die cavity section of this die block mold core and die mold core connects into semiellipse shape by two decentraction semicircles are smooth, amphitypy chamber section formation die cavity behind this die block mold core and the die mold core compound die, this die cavity is the ellipse, die block mold core and the die cavity section roughness of die mold core be 0.2 mu m, die block mold core and die mold core the profile is connected to the die cavity is 100 at the contained angle of utmost point post orientation 120 the beneficial effects of the utility model are that: through using this steel ball cold -heading mould improves structure, realize improving material utilization rate, improve the qualified level of product manufacture, reduce photosphere allowance, improve product interior tissue structure to improve mould life.
Description
Technical field
This utility model belongs to technical field of mold, particularly relates to a kind of steel ball cold heading die improved structure.
Background technology
Original mould structure is to use cone cydariform or waist-drum-shaped (as shown in Figure 1), and core material uses mould steel, and during cold-heading, the two poles of the earth become
Shape power is relatively big, causes following problem: steel-ball mill annulus thickness reaches 2.5mm, steel-ball mill annulus external diameter 2mm more than bigger than ball base, makes
Become the serious waste of steel；Tack is more, causes domestic steel ball manufacturer qualification rate the lowest, and the market competitiveness is poor；Because adding spare time
Amount is big, time-consumingly reaches 6-7 hour/dish in photosphere is processed, and causes power wastage, simultaneously too much, to environmental conservation because of grinding allowance
Bring adverse effect；The two poles of the earth and annulus surplus are big, because after processing capacity, finished product steel ball surface fibrous tissue of appearing is more, have a strong impact on
Crushing load and the steel ball of steel ball promote service life；Mould core many employings evanohm, deflection is big, and the life-span is short, inadaptable
Requirements of mass production.
Summary of the invention
The purpose of this utility model is the deficiency overcoming prior art to exist, and provides a kind of steel ball cold heading die improved structure,
Improve stock utilization, improve the qualified level of product manufacturing, reduce photosphere allowance, improve interiors of products histological structure, and
Improve die life.
The purpose of this utility model completes by following technical solution, including bed die core rod and mold core of clicking die, the described end
Mould core rod all uses wolfram steel material to make with mold core of clicking die, and the die cavity section of this bed die core rod and mold core of clicking die is by two the most not partly
Circular arc is smoothly connected into half elliptic, and two die cavity sections after this bed die core rod and mold core of clicking die matched moulds form die cavity, and this die cavity is
Oval.
As preferably, the die cavity cross-sectional face roughness of described bed die core rod and mold core of clicking die is 0.2 μm.
As preferably, the die cavity of described bed die core rod and mold core of clicking die connects the profile angle in pole direction and is 100-120 °.
The beneficial effects of the utility model are: by using this steel ball cold heading die improved structure, it is achieved improve stock utilization,
Improve the qualified level of product manufacturing, reduce photosphere allowance, improve interiors of products histological structure, and improve die life.
Accompanying drawing explanation
Fig. 1 is existing steel ball cold heading die structural representation.
Fig. 2 is steel ball cold heading die structural representation of the present utility model.
Fig. 3 is die cavity structure for amplifying schematic diagram at the A of Fig. 2.
Label in accompanying drawing is respectively as follows: 1, bed die core rod；2, mold core of clicking die；3, die cavity section.
Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model done detailed introduction: as shown in accompanying drawing 2,3, this utility model includes bed die mould
Core 1 and mold core of clicking die 2, described bed die core rod 1 and mold core of clicking die 2 all use wolfram steel material to make, this bed die core rod 1 He
The die cavity section 3 of mold core of clicking die 2 is smoothly connected into half elliptic by two not concentric semi arches, this bed die core rod 1 and punch die mould
Two die cavity sections 3 after the 2-in-1 mould of core form die cavity, and this die cavity is oval.
Die cavity section 3 surface roughness of described bed die core rod 1 and mold core of clicking die 2 is 0.2 μm.
The die cavity of described bed die core rod 1 and mold core of clicking die 2 connects the profile angle in pole direction and is 100-120 °.
Using method of the present utility model is: first bed die core rod 1 and mold core of clicking die 2 are respectively charged in die sleeve, then dress
Part loads on cold headers, carries out cold-heading processing by normal procedure, just can get expected result.
This utility model is not limited to above-mentioned embodiment, no matter making any change, every employing on its shape or material are constituted
Structure provided by the utility model designs, and is all a kind of deformation of the present utility model, is all considered as protecting model at this utility model
Within enclosing.
