Abstract
The utility model belongs to a drawing die, particularly a die for drawing steel wires. The exiting dies only can draw steel wires with smooth surfaces, but the utility model designs a novel die which meets the requirement that the surfaces of steel wires have carved grooves. The sizing zone of the inner hole of a die core is made into 1-5 bulged shapes, and the height of the bulge h=0.20-0.45 mm, width b=0.5-1.8 mm, and the top radius R=0.45-0.90 mm. The mechanical property of steel wires made of the drawing die is superior to GB5223-85 prestressed concrete wires.
Description
The utility model relates to a kind of mould that is used to make steel wire, particularly makes the mould of prestressed concrete member goods arrangement of reinforcement with steel wire.
Steel wire or prestressed concrete member goods arrangement of reinforcement by the cold-drawn manufacturing all are to process according to the wire-drawing die of GB6883-86 " carbide alloy draws the mould blank ", GB6110-85 " carbide alloy Drawing die set pattern and size " and JB3943-85 " carbide alloy Drawing die set technical conditions " regulation with steel wire.Use the steel wire of this kind Drawing die set processing to be bright steel wire.
Along with science and technology development, to the new requirement of surface configuration proposition of steel wire, the concrete component goods arrangement of reinforcement steel wire especially for pre-tensioning system is made requires Steel Wire Surface to have cutting, to improve the bond stress between steel wire and the concrete.
Produce the requirement that the surface has the steel wire of cutting for satisfying, the utility model designs a kind of novel die, and the shape that has internal projection is made in the core rod hole that is about to mould.
The mould of the utility model design, its main feature is the transformation to core rod.Soon the core rod endoporus is made and is had the internal projection shape.According to the requirement of Steel Wire Surface groove, in the core rod hole, make 1-5 projection.The high h=0.20-0.45mm of each projection, wide b=0.5-1.8mm, protruding top radius R=0.45-0.90mm.
Below in conjunction with description of drawings.Fig. 1 is the core rod profilograph, and Fig. 2 is a core rod cross section enlarged drawing.R is a protruding top radius, and h is the height of projection, and b is that projection is wide.(1) core rod, (2) core rod working hole.
Accompanying drawing 2 is depicted as the core rod that endoporus has three projectioies.Protrusion along the circumferential direction full-size is protruding wide b, and the difference of work in the core rod when not having protrusion aperture d/2 and protrusion radius of a circle that peak constitutes is protruding object height h, and the protrusion top is a circular arc, and wherein radius of curvature is R.
1-5 projection is all at the sizing area of core rod, and evenly distribution on same plane.The mould diameter size d of the utility model design is divided into 4.0,4.5,5.0,5.5,6.0,6.5,7.0, eight class of 8.0mm, and bump sizes is as shown in table 1 on its inwall of the mould of different-diameter.With the relation of protruding number and bump sizes on its inner hole wall of mould of a kind of diameter shown in table 2-8.
Illustrate below.To produce φ 5.0 cutting steel wires is example, the steel wire permissible variation be (+0.02mm), (0.06mm), the core rod endoporus has three protrusions.Projection object height h=0.28 millimeter, wide b=1.0 millimeter, protruding top radius R=0.57 millimeter.
The material that the manufacturing core rod is used is WC-C.Projection on its inner hole wall can grind by specific process and form.GB6883-86 " carbide alloy draws the mould blank ", GB6110-85 " carbide alloy Drawing die set pattern size " and JB3943-85 standards such as " carbide alloy draw the mould technical conditions " are all carried out in other technical characterictic of mould of the utility model design such as core rod, die sleeve profile, size and specification requirement.
The mould of the utility model design has satisfied the requirement, the particularly requirement of prestressed concrete goods adapted cutting steel wire of production cutting steel wire fully.Its Mechanical Properties of Steel Wire and be better than standard GB 5223-85 " steel wires for prestressed concrete " with concrete bond stress.
Claims (3)
1, a kind of Drawing die set is especially for the mould of drawn wire, it is characterized in that the core rod endoporus made having 1-5 internal projection shape, protruding high h=0.20-0.45mm, protruding wide b=0.5-1.8mm, protruding top radius R=0.45-0.90mm.
2, mould according to claim 1 is characterized in that 1-5 projection on the core rod inner hole wall all at its sizing area, and evenly distributes on same plane.
