Abstract
The utility model discloses a direct-cooling hard alloy drawing mould. The direct-cooling hard alloy drawing mould comprises a steel sleeve and a mould core which is sleeved inside the steel sleeve, wherein hole structures of the mould core comprise a feeding area, a lubricating area, a working area, a sizing area and a discharging area; ring-shaped grooves are formed on the steel sleeves at the corresponding positions of the working area and the sizing area; and a water inlet passage and a water outlet passage are arranged on the steel sleeves which are rightly opposite to the ring-shaped groove. After the adoption of a direct water cooling way, water directly cools the mould core and flows circularly and circular cooling water takes away heat quickly, so that the service life of the direct-cooling hard alloy drawing mould is prolonged.
Description
Technical field
The utility model relates to a kind of direct-cooled sintered carbide wire drawing die tool.
Background technology
In the past, because China's merchant wire industry is backward relatively, wire-drawing equipment is outmoded, and drawing speed is lower (to be generally 3～5m/s), to adopt the wire drawing die of common material and traditional pass structure, can satisfy and produce needs.But entered the eighties since mid-term, some merchant wire enterprises of China, in succession from a collection of high-speed wire-drawing machine of external introduction with advanced level, be that the steel wire of 2.30mm is an example to draw diameter, drawing speed is generally all at 10～15m/s, drawing output is more than 20 tons, drawing speed is at a high speed damaged common die easily, destroys the surface of wire rod, and can make wire rod that the fracture of wire phenomenon takes place easily, energy consume significant during drawing, very uneconomical.Because under the situation of high speed drawing, mould is easy to generate high temperature, the high-temperature condition bed die damages easily, so the cooling of mould is a problem that must solve, and prior art can not satisfy the three-dimensional of high speed drawing, output and speed and produce needs.
The utility model content
The technical problems to be solved in the utility model provides that a kind of drawing speed is very fast, die life is higher, can circulate and repeatedly use and the direct-cooled preferably sintered carbide wire drawing die tool of wire surface quality of drawing.
Content of the present utility model is that it comprises steel bushing and is sleeved on the interior core rod of steel bushing, the pass structure of described core rod is divided into entrance region, lubricated district, workspace, sizing area and outlet area, the steel bushing of described workspace and sizing area correspondence position is provided with ring-shaped groove, is provided with intake tunnel and exhalant canal over against the steel bushing of ring-shaped groove.
The number of described intake tunnel is at least one, and the number of exhalant canal is three.
The beneficial effects of the utility model are, the utility model is equally packed in the Wire drawing die box by common die, during wire drawing work, powdered lubricant is brought in the pressure core rod by the wire rod of high speed drawing, because angle of wedge effect, powdered lubricant is pushed and is wrapped in uniformly on the wire surface that is drawn by wire rod and pressure core rod, when the wire rod that has wrapped up one deck lubricating film reduced during through the sizing core rod to the sizing core rod wearing and tearing, thereby improved the drawing output of mould, the utility model is in the process of drawing simultaneously, and intake tunnel enters cold water, arrives in the circular passage, cooling is because the core rod that generates heat in the drawing process, cold water comes out from exhalant canal immediately, takes away heat, because the ringing of cooling water, reduce the temperature of core rod, improved service life of the present utility model.The utility model is simple in structure, and each parts dismounting is quick, and mould is easy for installation and can lower cost of transportation.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of exhalant canal of the present utility model.
In the drawings, 1 entrance region, 2 lubricated districts, 3 workspaces, 4 intake tunnels, 5 sizing areas, 6 outlet areas, 7 steel bushings, 8 core rods, 9 exhalant canals, 10 ring-shaped grooves.
The specific embodiment
As shown in drawings, the utility model comprises steel bushing 7 and the core rod 8 that is sleeved in the steel bushing 7, the pass structure of described core rod is divided into entrance region 1, lubricated district 2, workspace 3, sizing area 5 and outlet area 6, the steel bushing 7 of described workspace 3 and sizing area 5 correspondence positions is provided with ring-shaped groove 10, is provided with two intake tunnels 4 and three exhalant canals 9 over against the steel bushing 7 of ring-shaped groove 10.
The utility model adopts the mode of direct water-cooling, and water directly is cooled on the core rod 8, and circulates, and recirculated cooling water is taken away heat rapidly; The utility model adopts the cold-press method assembling, increases pretightning force; Steel bushing 7 of the present utility model and core rod 8 are concentric, and steel bushing 7 can be reused; Decrease of temperature has been avoided the lubricant charing, improves drawing speed, has improved service life of the present utility model.
