Abstract
The utility model relates to a wire-drawing die diamond blank positioning device. The wire-drawing die diamond blank positioning device comprises a pressing bar and a positioning sleeve. The lower end of the pressing bar can be embedded in an inner cavity of a wire-drawing die steel sleeve; the bar body of the pressing bar is cylindrical; a platform for fixing diamond blanks is arranged at the bottom of the bar body; a groove is formed in the bottom of the positioning sleeve, and is matched with the shape of the redial-direction section of the wire-drawing die steel sleeve, and the wire-drawing die steel sleeve can be partially embedded in the groove; a perpendicular guide hole communicated with the circular groove is formed in the middle of the top of the positioning sleeve, the shape of the section of the perpendicular guide hole is matched with the shape of the section of the bar body of the pressing bar, and the circle center of the perpendicular guide hole and the circle center of the circular groove coincide. The wire-drawing die diamond blank positioning device is relatively simple in structure and precise in positioning and can improve the quality of a die and rate of finished products because positioning operation will not cause deflection of the diamond blanks.
Description
Technical field
The utility model relates to a kind of wire drawing die processing unit (plant), and specifically a kind of wire drawing die diamond blank is anticipated a device.
Background technology
Wire drawing die is a kind of mould of drawing metallic fiber material.This wire drawing die passes through sinter setting diamond blank in the middle of being generally cylindrical steel bushing, reprocesses a nib with definite shape by the diamond center, size decreases when metal is hauled and passes nib, and even shape all changes.Therefore, in the wire drawing die process, the diamond blank must be placed on the center of the sintering powder of wire drawing die steel bushing inner chamber.At present, the wire-drawing die diamond blank is anticipated the position and is generally adopted locating bar location, and the locating bar bottom can embed in wire drawing die steel bushing inner chamber.During positioning action, first be fixed on the diamond blank in the middle of the locating bar bottom end face by bonding agent at microscopically, the locating bar that will be bonded with again the diamond blank is put into corresponding wire drawing die steel bushing inner chamber, by exerting pressure, in the sintering powder in diamond blank embedding wire drawing die steel bushing inner chamber, then take out locating bar, to diamond blank top filling agglomerated powder and compacting, then through sinter molding.Locate in this way, because the gap of locating bar front end and wire drawing die steel bushing intracavity sidewall is larger, can only rely on artificial experience to locate, thereby setting accuracy is lower, and also easily causes the diamond blank eccentric when taking out locating bar, causes blank and die sleeve center decentraction, because the diamond blank diameter is less, the diamond blank is placed and is departed from the center, waste product easily occurs during the processing nib, and the die life that perhaps processes reduces.
Summary of the invention
The purpose of this utility model is for the deficiencies in the prior art, provides a kind of wire drawing die diamond blank to anticipate a device, not only can improve diamond blank and anticipate an accuracy, improves yield rate, can also improve working (machining) efficiency.
For the foregoing invention purpose, the technical solution adopted in the utility model is: comprise that a lower end can embed the pressure bar of wire drawing die steel bushing inner chamber, the barred body of described pressure bar is cylindric, and barred body bottom has the platform of fixed diamonds blank; A positioning sleeve, described positioning sleeve bottom has the groove that supplies wire drawing die steel bushing radial section form fit, can supply the wire drawing die steel bushing partly to embed, the positioning sleeve crown center has the vertically-guided hole that communicates with groove, cross section, described vertically-guided hole and pressure bar barred body cross sectional shape coupling, the vertically-guided hole overlaps with the center of circle of groove.During positioning action, first the groove of positioning sleeve by the bottom is enclosed within on the wire drawing die steel bushing, then the pressure bar with bonding diamond blank is placed in positioning sleeve, by press, pressure bar is exerted pressure downwards, when compacting is carried out to the agglomerated powder of wire drawing die steel bushing inner chamber in pressure bar bottom, the diamond blank that is bonded in the pressure bar bottom is embedded in agglomerated powder, then upwards extract pressure bar, the diamond blank is retained in the agglomerated powder of wire drawing die steel bushing inner chamber, thereby completes positioning action.
Further, the height of described groove is not less than 1/4th of wire drawing die steel bushing axial length.
Further, the pressure-bearing platform that a cross section increases is arranged at described pressure bar top.
The beneficial effects of the utility model are: this apparatus structure is simpler, and between positioning sleeve and wire drawing die steel bushing, position by periphery respectively between pressure bar and positioning sleeve, machining accuracy is high, registration.And compacting is carried out to agglomerated powder in the pressure bar bottom, and the diamond blank is combined with agglomerated powder closely, upwards extracts the pressure bar operation and can not cause diamond blank deflection; Further, pressure bar when upwards taking out pressure bar, does not affect the diamond blank relative to doing upper and lower vertical the movement with positioning sleeve, thereby the location is very accurate, can guarantee that the diamond blank is embedded in the centre, can effectively improve die quality, improves yield rate.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the positioning action schematic diagram.
The specific embodiment
As shown in Figure 1, the utility model wire drawing die diamond blank is anticipated a device, comprising: a lower end can embed the pressure bar 1 of wire drawing die steel bushing inner chamber 31, and the barred body of described pressure bar 1 is cylindric, and barred body bottom has the platform 11 of fixed diamonds blank;
A positioning sleeve 2, described positioning sleeve 2 bottoms have the groove 21 that supplies wire drawing die steel bushing radial section form fit, can supply the wire drawing die steel bushing partly to embed, positioning sleeve 2 crown centers have the vertically-guided hole 22 that communicates with bottom groove 21,22 cross sections, vertically-guided hole and pressure bar 1 barred body cross sectional shape coupling, vertically-guided hole 22 overlaps with the center of circle of groove 21.
Consider that positioning sleeve can stably be enclosed within on the wire drawing die steel bushing, the height of described groove 21 is not less than 1/4th of wire drawing die steel bushing axial length.
Exert pressure for convenience of press, the pressure-bearing platform 12 that pressure bar 1 top has a cross section to increase.
the utility model positioning action as shown in Figure 2, on the opening up workbench 6 that is placed on press of wire drawing die steel bushing inner chamber 31, again the groove 21 of positioning sleeve 2 by the bottom is enclosed within on wire drawing die steel bushing 3, then the pressure bar 1 of bonding diamond blank 5 is placed in the vertically-guided hole 22 of positioning sleeve 2, by press, pressure bar 1 is exerted pressure downwards, when compacting is carried out to the agglomerated powder 4 of wire drawing die steel bushing inner chamber 31 in pressure bar 1 bottom, to be bonded in the diamond blank 5 embedding agglomerated powders 4 of pressure bar bottom, then upwards extract pressure bar 1, diamond blank 5 is retained in the agglomerated powder 4 of wire drawing die steel bushing inner chamber 31, thereby complete positioning action.
