Abstract
A kind of drawing die, comprise overcoat and core rod, in overcoat, be processed with endoporus, locating piece and clamp are housed in endoporus, in the square hole formed by locating piece and clamp, core rod is housed, described core rod has at least one datum level coordinated with described locating piece.This mould has the advantage that machining accuracy is high, reusing strong, save cost.
Description
Technical field
The utility model relates to carbide alloy stretching technique field, especially relates to a kind of high accuracy, core rod removable vertical pulling machine drawing die.
Background technology
In prior art, copper material, steel manufacturer be the general drawing die adopting Tie Tao tungsten carbide button core rod in production cold-drawn tubing or bar, owing to requiring high to the linearity of straight tube or straight excellent series products, therefore require also high to the iron cover of mould and the relative position degree of nib, so in Mould Machining, one is the position degree requirement of the endoporus of the male cone (strobilus masculinus) that will ensure that iron overlaps and iron cover, two is to ensure the cylindrical of carbide alloy core rod and the position degree requirement of nib, and its core rod of therefore common drawing die is non-exchange.
Application number is the wire drawing die disclosing a kind of replaceable core rod in the utility application of 201310455548.0, this mould comprises steel bushing and core rod, steel bushing is stainless steel, core rod is carbide alloy material, adopt between steel bushing and core rod and be threaded, steel bushing periphery is offered positioning screw hole structure, coordinate dog screw to use, the axial and circumferential realized between steel bushing and core rod by dog screw are located.What this mould emphasis solved is the problem that core rod is changed, but its precision of location only realized by dog screw obviously can not meet the needs of high accuracy drawing.
Utility model content
The purpose of this utility model is to overcome the shortcoming existed in prior art, there is provided a kind of can the drawing die of convenient changing core rod, for ensureing the required precision after core rod replacing, locating piece has the datum level coordinated with core rod high accuracy, the technical scheme adopted is: a kind of drawing die, comprise overcoat and core rod, it is characterized in that: in described overcoat, be processed with endoporus, locating piece and clamp are housed in described endoporus, in the square hole formed by described locating piece and clamp, described core rod is housed, described core rod has at least one datum level coordinated with described locating piece.
Technical characteristic of the present utility model also has: the datum level that described locating piece coordinates with core rod is two, and two datum levels are mutually vertical.
Technical characteristic of the present utility model also has: described locating piece is arranged in the endoporus of overcoat by bolt.
Technical characteristic of the present utility model also has: described clamp is two, and two pieces of clamps are fixed in the endoporus of overcoat by fishbolt.
Technical characteristic of the present utility model also has: described core rod is carbide alloy, and the endoporus of core rod is regular hexagon endoporus.
Technical characteristic of the present utility model also has: the diameter of bore of described overcoat is 90mm.
The beneficial effects of the utility model are: 1) this mould can realize the precise match between carbide alloy core rod and overcoat, and under the prerequisite ensureing required precision, can change core rod easily, realize the recycling of overcoat; 2) locating piece and core rod complete precise match by two orthogonal locating surfaces; 3) this mould has the advantage that machining accuracy is high, reusing strong, save cost.
Accompanying drawing explanation
Accompanying drawing 1 is the utility model structural representation, accompanying drawing 2 is overcoat front views, accompanying drawing 3 is left views of accompanying drawing 2, accompanying drawing 4 is structural representations of locating piece, accompanying drawing 5 is A-A sectional views of accompanying drawing 4, accompanying drawing 6 is front views of clamp, and accompanying drawing 7 is left views of accompanying drawing 6, and accompanying drawing 8 is structural representations of core rod.Wherein, 1 is overcoat, and 2 is core rods, and 3 is locating pieces, and 4 is clamps, and 5 is locating holes, and 6 is holes for clamping.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described.The utility model discloses a kind of drawing die, comprise overcoat 1 and the core rod 2 being placed in overcoat 1, endoporus is processed with in overcoat 1, locating piece 3 and clamp 4 are housed in endoporus, in the square hole be jointly made up of locating piece 3 and clamp 4, core rod 2 is housed, locating piece 3 is arranged on the endoporus of overcoat by the bolt being arranged in locating hole 4.Pretightning force is delivered on core rod 2 by the fishbolt being arranged in holes for clamping 6 by clamp 4, thus ensures that the pretightning force that core rod 2 is subject to is even, prevents breaking of core rod 2.In order to the needs of positioning precision, core rod 2 has at least one datum level coordinated with locating piece 3.This place core rod 2 is carbide alloy core rod, and the endoporus of core rod 2 is regular hexagon endoporus.
In the present embodiment, the datum level that locating piece 3 coordinates with core rod 2 is two, and two datum levels are mutually vertical; Clamp 4 is two, and two pieces of clamps 4 are fixed in the endoporus of overcoat 1 by fishbolt.
The drawing die needed for regular hexagon copper rod being 10mm for a length of side is specifically described the utility model.
1) process that external diameter is Φ 120mm, thickness is the overcoat 1 of 40mm iron cover as present embodiment, and processes the endoporus of Φ 90mm, its outlet diameter is Φ 25mm, and overcoat 1 is processed the locating hole 5 of M6 and the holes for clamping 6 of M6;
2) locating and machining block 3, locating piece 3 thickness is 25mm, R is 45mm, and the position perforate of corresponding locating hole 5, datum level A and B controls in 0.05mm relative to endoporus center degree deviation;
3) locating piece 3 is fixed in overcoat 1 by M6 hexagon socket head cap screw, and the arc surface of locating piece 3 and the inner hole surface of overcoat are closely cooperated, core rod 2 and clamp 4 are assembled together, and by M6 hexagon socket head cap screw, clamp are compressed;
Its linearity of copper rod of the regular hexagon copper rod drawing mould processing of process and assemble reaches more than 0.5mm/m according to the method described above.
Certainly; above-mentioned explanation is not limitation of the utility model; the utility model is also not limited only to above-mentioned citing, the change that those skilled in the art make in essential scope of the present utility model, remodeling, interpolation or replacement, also belongs to protection domain of the present utility model.
