Abstract
The invention discloses a steel wire drawing technique and device, comprising that 1, clamping and drawing the front of the steel wire which needs to pass through mould and drawn, 2, heating the steelwire, 3, forcing the clamped steel wire, to extend and crack the steel wire, removing the broken waste steel wire to obtain the mould-through steel wire with sharp end. The invention can improve working efficiency and improve plasticity.
Description
Technical field
The present invention relates to a kind of steel wire tip drawing device.
Background technology
In the metallic article wire drawing, need before the steel wire drawing steel wire is processed into a tip, just can penetrate in the wire drawing die then.Steel wire tip drawing is generally to be by emery wheel sharpening, manual pull method or curved roll pointing at present, its medium plain emery wheel sharpening and manual pull method are manual operations, the steel wire loss is big, work efficiency is poor, circularity is uncontrollable, makes metal produce phase transformation simultaneously, and product quality is uncontrollable, steel wire tip rough surface in addition, form irregular water caltrop, to the workspace and the sizing area existence scuffing phenomenon of wire drawing die, the service life of directly having reduced mould.The curved roll pointing is compared with above-mentioned two kinds of methods and has just been improved the part operating efficiency, has above problem equally.Because it has used cold-rolling process, form the hardening by cooling of metal inside during pointing rapidly, brought and worn the mould difficulty, steel wire often ruptures when serious, causes the loss from spoilage of wire-drawing die.
Summary of the invention
The invention provides a kind of steel wire tip drawing device, use this device can be apace to carry out top-notchly, improved operating efficiency greatly wearing the mould steel wire, steel wire improves internal organizational structure through heating simultaneously, improved plasticity, got ready, prolonged the service life of mould for follow-up steel wire drawing.
Technical scheme of the present invention is as follows: the steel wire tip drawing device, comprise support, left binding clasp, right binding clasp, core print seat and heater, left side binding clasp is rack-mount, and right binding clasp passes core print seat and can rotate around core print seat, and heater is between left and right binding clasp.
Be provided with reel between described left binding clasp and the heater; Described right binding clasp comprises fixture block, to fixture block, lever, sleeve pipe and operating grip, sleeve pipe passes core print seat and can rotate around core print seat, fixture block be installed in the sleeve pipe fixture block is relative, lever stretches into that both connect with threaded engagement in the sleeve pipe, lever stretch in the sleeve pipe an end with fixture block is fixedlyed connected, the other end is provided with operating grip.
Described heater comprises the positive and negative electrode rod, and the positive and negative electrode rod links to each other with low-tension supply.
After adopting as above technical scheme, during top-notch steel wire, with wire clip between left and right binding clasp, the energising of positive and negative electrode rod is heated steel wire, rotates right binding clasp again steel wire is stretched until fracture, and fracture place steel wire is tapered in drawing process, form the tip in fracture place, realization is top-notch to steel wire, and is easy and simple to handle, the work efficiency height.Steel wire slowly cools to normal temperature again through heating, has improved crystal grain, has eliminated tissue defects, has reduced hardness, has improved plasticity, is convenient to the further drawing of steel wire, has prolonged the service life of wire-drawing die.

The specific embodiment
With reference to accompanying drawing, a kind of steel wire tip drawing device, it comprises support 1, left binding clasp 2, reel 3, heater, right binding clasp and core print seat 4, and left binding clasp 2, reel 3, heater are installed on the support 1, and left binding clasp 2 can adopt pneumatic gripping.Right binding clasp is arranged in core print seat 4 and can rotates around core print seat 4, and core print seat 4 is installed in bearing 5 tops, and bearing 5 is fixed on the support 1 by installing plate 6, and heater is between reel 3 and right binding clasp.Heater comprises positive electrode rod 7 and negative electrode rod 8, two electrode bars and support 1 insulating mounting, and the positive and negative electrode rod links to each other with low-tension supply, and the connection of low-tension supply is controlled by switch.Distance between the positive and negative electrode rod can be regulated, and as open a slotted eye on support, one of them electrode bar can be installed in the diverse location of slotted eye.
Right binding clasp comprises fixture block 9, to fixture block 10, lever 11, sleeve pipe 12 and operating grip 13, sleeve pipe 12 passes core print seat 4 and can rotate around core print seat 4, fixture block 9 with to fixture block 10 relative being installed in the sleeve pipe 12, lever 11 stretches into that both connect with threaded engagement in the sleeve pipe 12, lever 11 stretch in the sleeve pipe 12 an end with fixture block 10 is fixedlyed connected, the other end is provided with operating grip 13.
Steel wire tip drawing technology, at first needs are worn and snapped in the left binding clasp 2 after the top-notch steel wire of mould is reserved the about 0.6m of reasonable length, the rear steel wire encloses around two along reel 3, through heater, snap in the right binding clasp, the rotating operation handle 13 again, make lever 11 relative sleeve pipe 12 motions, promotion is withstood fixture block 9 forward to fixture block 10, thereby steel wire is strained clamping.Connect low-tension supply, the positive and negative electrode rod is to more than the tension clamping section steel wire heating to 700 ℃, pulling operating grip 13 turns clockwise, right binding clasp is that fulcrum clockwise rotates the bringing-up section steel wire application of force with core print seat 4, make bringing-up section steel wire generation plastic elongation until fracture, remove the waste silk section of right-hand member, take out the steel wire of left side front end band tip.
