Abstract

The utility model discloses a tapered direct cooling die which comprises a die sleeve, a die core, a cooling water inlet, a cooling water tank and a cooling water outlet, wherein the die sleeve connection the die core, the cooling water inlet, the cooling water outlet and the cooling water tank; the die core is connected with the cooling water tank; the die sleeve is made of 45 steel; the 1:15 taper is pressed on the inner hole of the die sleeve; the die core is made of a YG3X hard alloy; the 1:15 taper is processed on the outer circle of the die core; the die core is pressed into the die sleeve at a depth of 2.5-3.0 mm; the die core and the die sleeve adopt a cold pressing manner; a cooling groove is formed in the inner wall of the die sleeve; and the width of the cooling water tank covers 3/4 of the height position of the die core; the cooling water tank is distributed along the circumference of the die core; the cooling water inlet and the cooling water outlet are formed outside the tank; and the cooling water outlet is located at the lower end, and that ponding water can cannot be cooled completely is prevented. The tapered direct cooling die has the advantages that the tapered direct cooling die is reasonable in structure, convenient to mount, simple in operation, long in service life, tight in sealing, safe, reliable and the like.

Description

The direct-cooled mould of taper

Technical field

The utility model relates to the direct-cooled mould of a kind of taper, is particularly useful for the wire drawing die cooling procedure of shredded dried bean curd drawing process in the wire pulling process.

Background technology

The wire pulling process usually is divided into shredded dried bean curd and draws and the wet type pulling process, what shredded dried bean curd drew usually employing is that wire drawing die interpolation lubricant draws, because the high temperature that pulling process produces is often so that carbonization appears in lubricant, select water cooling mode for fear of lubricant carbonization wire drawing die, it is lubricated that but lubricant is dry state, lubricant will lose efficacy during hygrometric state, and the Bamboo-shaped defective appears in unlubricated dose of lubrication wiredrawing wire rod afterwards simultaneously.

Summary of the invention

The utility model has been developed the direct-cooled mould of a kind of taper, and its objective is provides a kind of rational in infrastructure, easy for installation, simple to operate, and long service life is airtight tight, the direct-cooled mould of safe and reliable taper.

For achieving the above object, the utility model device is achieved through the following technical solutions.The direct-cooled mould of taper, comprise die sleeve, core rod, cooling water inlet, bosh, coolant outlet, die sleeve is connected with core rod, and die sleeve is connected with cooling water inlet, die sleeve is connected with coolant outlet, die sleeve is connected with bosh, and core rod is connected with bosh, and die sleeve adopts 45 steel, the die sleeve endoporus is processed into the tapering of 1:15, core rod is selected the carbide alloy of YG3X, and the core rod Excircle machining becomes the 1:15 tapering, and core rod is pressed into the die sleeve degree of depth 2.5 ~ 3.0mm, the approach cone of core rod, Lubricanting cone, Drawing cone, calibrating strap goes out prostomum to be finished at the high speed sharpening machine, core rod and die sleeve adopt the mode of colding pressing, and the die sleeve inwall has cooling bath, and the bosh width is contained core rod 3/4 height and position, along the core rod circle distribution, groove has cooling water inlet and coolant outlet outward, and coolant outlet is positioned at low side, avoids ponding to cool off fully.

The beneficial effects of the utility model are, utilize the taper fit of die sleeve and core rod, so that die sleeve and core rod gapless, utilize the cooling water outlet and inlet on the die sleeve so that core rod is able to timely cooling, integral device has rational in infrastructure, and is easy for installation, simple to operate, airtight tight, long service life, the advantage such as safe and reliable.

Description of drawings

Fig. 1 is the structural representation of the direct-cooled mould of the utility model taper.

The specific embodiment

Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.

As shown in Figure 1, the direct-cooled mould of taper, comprise die sleeve 1, core rod 2, cooling water inlet 3, bosh 4, coolant outlet 5, die sleeve 1 is connected with core rod 2, die sleeve 1 is connected with cooling water inlet 3, and die sleeve 1 is connected with coolant outlet 5, and die sleeve 1 is connected with bosh 4, core rod 2 is connected with bosh 4, die sleeve 1 adopts 45 steel, and die sleeve 1 endoporus is processed into the tapering of 1:15, and core rod 2 is selected the carbide alloy of YG3X, core rod 2 Excircle machinings become the 1:15 tapering, core rod 2 is pressed into die sleeve 1 degree of depth 2.5 ~ 3.0mm, the approach cone of core rod 2, Lubricanting cone, Drawing cone, calibrating strap goes out prostomum to be finished at the high speed sharpening machine, and core rod 2 adopts the mode of colding pressing with die sleeve 1, die sleeve 1 inwall has cooling bath, bosh 4 width are contained core rod 3/4 height and position, and along the core rod circle distribution, groove has cooling water inlet 3 and coolant outlet 5 outward, coolant outlet 5 is positioned at low side, avoids ponding to cool off fully.
