Abstract
The utility model discloses a drawing die capable of improving cooling effect. The drawing die comprises a die core, and a die sleeve sleeves the die core. The drawing die is characterized in that the die sleeve is provided with a water inlet pipeline and a water outlet pipeline inside, and the water inlet pipeline and the water outlet pipeline are communicated through circumferential circulating pipelines. According to the above structure, when wire billets deform by drawing to generate deformation heat and friction heat, cooling water is injected into the die sleeve through the water inlet pipeline and circumferentially flows in the die sleeve circularly and flows out through the water outlet pipeline, so that the die sleeve and the die core can be cooled in time, and deformation heat and friction heat can be guided out in time. Accordingly, product quality is unaffected, and wire breakage and die explosion are avoided. Meanwhile, lubricating oil for spraying a bell mouth of the drawing die where the wire billets enter is omitted, production cost is reduced and deoiling process is reduced.
Description
Technical field
The utility model relates to stretching die technical field, is specifically related to a kind of stretching die that can improve cooling effect.
Background technology
Stretching is one of common Metal Forming method, copper and copper alloy material not only can reach accurate size by the stretching of stretching die, profile, and can meet various performance requirements, but when the stretched moding shape of line base, can produce distortion heat and frictional heat, if the cooling rising along with temperature not only can affect product quality not in time, and meeting fracture of wire, the generations such as burst-mode, the conventional type of cooling is to adopt lubricating oil to spray online base to enter the horn mouth place of stretched film, but this kind of type of cooling is not very good, along with stretching continues to carry out a large amount of hot polymerization collection, due to the core rod of tungsten-cobalt alloy material and the die sleeve thermal coefficient of expansion of No. 45 steel different, the gathering of large calorimetric can reduce die sleeve to core rod pretightning force, just be very easy to explosion when losing core rod after enough pretightning forces, and the use of lubricating oil also can increase production cost and follow-up oil removing operation.
Utility model content
The utility model, for the above-mentioned deficiency of prior art, provides a kind of good cooling results, and core rod is difficult for explosion and can improves the stretching die of cooling effect.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of stretching die that can improve cooling effect, comprise core rod, core rod outside is sheathed with die sleeve, it is characterized in that: in described die sleeve, be provided with inlet channel and outlet conduit, described inlet channel and outlet conduit are interconnected by circumferential circulating line.
Adopt said structure, in the time of the stretched moding shape of line base, produce distortion heat and frictional heat, in die sleeve, pass into cooling water by inlet channel, after cooling water circumferentially circulating in die sleeve, flow out through outlet conduit again, thereby realization is cooling in time to die sleeve and core rod, distortion heat and frictional heat are derived in time; Thereby can not affect product quality, there will not be the phenomenon such as fracture of wire, burst-mode; Also enter the horn mouth place of stretched film without adopting again lubricating oil to spray online base, reduced production cost, reduced oil removing operation simultaneously.
As preferably, described circumferential circulating line be arranged at die sleeve and core rod junction and radially (die sleeve and core rod are radially) extend in die sleeve and core rod; Adopt said structure, can increase the contact area of cooling water and die sleeve and core rod, reach better cooling effect, cooling, cooling more fast.
As preferably, it is the radially 1/3-2/3 of maximum ga(u)ge of core rod that described circumferential circulating line radially extends to the degree of depth in core rod; Adopt said structure, can fully keep the contact area of cooling water and core rod, reach better cooling effect; Can ensure again hardness and the intensity of core rod, can produce distortion heat and frictional heat when the online stretched moding shape of base time, be difficult for making core rod to cause damage simultaneously.
As further preferably, described circumferential circulating line radially extend to the degree of depth in core rod be core rod radially maximum ga(u)ge 1/2; Adopt said structure, can ensure core rod intensity, can make again cooling water derive in time core rod heat.
Brief description of the drawings
Accompanying drawing the utility model can improve the stretching die structural representation of cooling effect.
Detailed description of the invention
Enter below in conjunction with accompanying drawing by embodiment and describe the utility model in detail, but the utility model is not only confined to following examples.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of stretching die that can improve cooling effect, comprise core rod 1, core rod 1 outside is sheathed with die sleeve 2, it is characterized in that: in described die sleeve 2, be provided with inlet channel 2.1 and outlet conduit 2.2, described inlet channel 2.1 is interconnected by circumferential circulating line 3 with outlet conduit 2.2.
Adopt said structure, in the time of the stretched moding shape of line base, produce distortion heat and frictional heat, in die sleeve, pass into cooling water by inlet channel, after cooling water circumferentially circulating in die sleeve, flow out through outlet conduit again, thereby realization is cooling in time to die sleeve and core rod, distortion heat and frictional heat are derived in time; Thereby can not affect product quality, there will not be the phenomenon such as fracture of wire, burst-mode; Also enter the horn mouth place of stretched film without adopting again lubricating oil to spray online base, reduced production cost, reduced oil removing operation simultaneously.
Circumferential circulating line 3 described in the utility model be arranged at die sleeve 2 and core rod 1 junction and radially (die sleeve and core rod are radially) extend in die sleeve 2 and core rod 1; Adopt said structure, can increase the contact area of cooling water and die sleeve and core rod, reach better cooling effect, cooling, cooling more fast.
The degree of depth that circumferential circulating line 3 described in the utility model radially extends in core rod 1 is the radially 1/3-2/3 of maximum ga(u)ge of core rod 1; Adopt said structure, can fully keep the contact area of cooling water and core rod, reach better cooling effect; Can ensure again hardness and the intensity of core rod, can produce distortion heat and frictional heat when the online stretched moding shape of base time, be difficult for making core rod to cause damage simultaneously.As further preferably, described circumferential circulating line radially extend to the degree of depth in core rod be core rod radially maximum ga(u)ge 1/2; Adopt said structure, can ensure core rod intensity, can make again cooling water derive in time core rod heat.
