Abstract

The invention discloses a wire drawing die capable of replacing a die core. The wire drawing die comprises a steel sleeve and the die core; the steel sleeve is stainless; the die core is made of a hard alloy material; the steel sleeve and the die core are connected by threads; a positioning screw hole structure is formed in the circumference surface of the steel sleeve, and is matched with a positioning screw so as to achieve the axial and peripheral positioning of the steel sleeve and the die core. The invention discloses the wire drawing die capable of replacing the die core. The wire drawing die is reasonable in structure design, and the die core can be detached and replaced, so that the replacement cost of the wire drawing die is reduced effectively; meanwhile, the die core is convenient to dismount and mount, is stable in performance of connection with the steel sleeve, shows favorable mechanical performance in use, and effectively guarantees the favorable service life and using performance of the wire drawing die.

Description

A kind of wire drawing die of replaceable core rod
Technical field
The present invention relates to a kind of wire drawing die, relate in particular to the removable novel wire drawing die of a kind of core rod, belong to technical field of mold.
Background technology
Wire drawing die is the instrument that carries out metal wire (rod) material extending.There is a nib at the center of all wire drawing dies, and the shape of nib can be circular, square or octagonal.Its size decreases when metal is hauled through nib, even shape all can change.Owing to having larger friction and vibration in the wire drawing process, therefore, wire drawing die is a kind of mould of very easy loss, and wire drawing die maintenance and renewal cost have accounted for drawing and produced more than 50% of total consumptive material.For this reason, the manufacturing cost of reduction wire drawing die becomes the important research topic of current mould applications service life with improving.
Existing wire drawing die mainly is comprised of steel bushing and core rod, and steel bushing is generally stainless steel, and core rod can be selected the materials such as carbide alloy, steel alloy, natural diamond or artificial diamond, and both realize permanent connection by interference fit or welding.Therefore, a kind of wire drawing die can only complete a kind of drawing operation of dimension wire; Simultaneously, once steel bushing and core rod one of them destroy and to cause losing efficacy because being subject to external cause, people must change whole wire drawing die, easily cause the waste of resource, have increased production cost.
Summary of the invention
For the demand, the invention provides a kind of wire drawing die of replaceable core rod, this wire drawing die reasonable in design, its core rod is detachable, effectively reduces the cost that wire drawing die is changed.
The present invention is a kind of wire drawing die of replaceable core rod, this wire drawing die comprises steel bushing and core rod, steel bushing is stainless steel, core rod is the carbide alloy material, adopt and be threaded between described steel bushing and core rod, offer the positioning screw hole structure on described steel bushing periphery, coordinate dog screw to be used, to realize the axial and circumferential location of steel bushing and core rod.
In a preferred embodiment of the present invention, the be connected screw thread of use of described steel bushing and core rod is triangle thread, and this screw thread is single thread, and pitch is 3.5mm, and rotation direction is dextrorotation.
In a preferred embodiment of the present invention, the large footpath of external screw thread on described core rod outer round surface is 30mm.
In a preferred embodiment of the present invention, described core rod middle part is the nib structure, and its upper surface outer ring arranges the hex nut structure.
In a preferred embodiment of the present invention, described positioning screw hole structure is opened in the middle part of steel bushing, and its quantity can be one, also can two or three need to be set according to using.
In a preferred embodiment of the present invention, described positioning screw hole is the counter sink structural design, and the large footpath of its internal thread hole is 3mm, and the specification of the dog screw be mated is M3, and length is about 1.5cm.
The present invention has disclosed a kind of wire drawing die of replaceable core rod, this wire drawing die reasonable in design, and its core rod is detachable and change the cost while effectively reducing the wire drawing die replacing; Simultaneously, the core rod easy accessibility, stable with the switching performance of steel bushing, show good mechanical property during use, effectively guaranteed service life and serviceability that wire drawing die is good.
The accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation:
Fig. 1 is the structural representation of the wire drawing die of the replaceable core rod of the embodiment of the present invention;
In accompanying drawing, the mark of each parts is as follows: 1, steel bushing, 2, core rod, 3, positioning screw hole, 4, nib, 5, hex nut.
The specific embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present invention is described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that, protection scope of the present invention is made to more explicit defining.
Fig. 1 is the structural representation of the wire drawing die of the replaceable core rod of the embodiment of the present invention; This wire drawing die comprises steel bushing 1 and core rod 2, steel bushing 1 is stainless steel, core rod 2 is the carbide alloy material, adopt and be threaded between described steel bushing 1 and core rod 2, offer positioning screw hole 3 structures on described steel bushing 1 periphery, coordinate dog screw to be used, locate to realize steel bushing 1 and the axial and circumferential of core rod 2.
In the wire drawing die of the replaceable core rod that the present invention mentions, the be connected screw thread of use of steel bushing 1 and core rod 2 is triangle thread, and this screw thread is single thread, and pitch is 3.5mm, and rotation direction is dextrorotation, and the large footpath of external screw thread on core rod 2 outer round surface is 30mm; The bonding strength of this screw thread is high, has given core rod 2 good axial location ability.
The middle part of core rod 2 is nib 4 structures, and its shape can be circular, square or octagonal; The outer ring of nib 4 upper surfaces arranges hex nut 5 structures, and its specification can be M12, M14 or M16, and this respective outer side edges spanner uses, for realizing the dismounting of core rod 2.
Positioning screw hole 3 structures are opened in the middle part of steel bushing 1, and its quantity can be one, also can two or three need to be set according to using; Positioning screw hole 3 is the counter sink structural design, and the large footpath of its internal thread hole is 3mm, and the specification of the dog screw be mated is M3, and length is about 1.5cm.
During core rod 2 dismounting, at first use screwdriver to unscrew dog screw, then use spanner to turn on core rod 2; During core rod 2 assembling, at first make the core rod 2 that screws up with a wrench, then use screwdriver screwed in place screw.
The present invention has disclosed a kind of wire drawing die of replaceable core rod, is characterized in: this wire drawing die reasonable in design, and its core rod is detachable and change the cost while effectively reducing the wire drawing die replacing; Simultaneously, the core rod easy accessibility, stable with the switching performance of steel bushing, show good mechanical property during use, effectively guaranteed service life and serviceability that wire drawing die is good.
The above; it is only the specific embodiment of the present invention; but protection scope of the present invention is not limited to this; any those of ordinary skill in the art are in the disclosed technical scope of the present invention; the variation that can expect without creative work or replacement, within all should being encompassed in protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain that claims were limited.
