Abstract
The utility model relates to equipment for continuously producing a copper flat wire in the manner of post-drawing precision rolling, which belongs to the technical field of transformer electromagnetic wire machining. The utility model has the technical scheme that the equipment for continuously producing the copper flat wire in the manner of post-drawing precision rolling comprises a drawing die (1), a drawing tank body (2), a copper wire (3), a precision roller (4) and a take-up shaft (5), wherein the copper wire is connected with the drawing tank body after passing through the drawing die; the copper wire coming out from the drawing tank body enters the precision roller; and the copper wire coming out from the precision roller reaches the take-up roller. The sectional area of a raw material copper rod is compressed after the raw material copper rod is drawn, so that the sectional area of the raw material copper rod is more close to that of a final copper flat wire, thus, the working load of the roller can be reduced, the local high-peak stress is avoided, and the service life of the roller is prolonged; the rolling process of the copper flat wire is a cold machining process; the copper rod can reach required sectional area, shape and dimensions under the acting force of the roller through plastic deformation; and by the machining technology of the equipment for continuously producing the copper flat wire in the manner of post-drawing precision rolling, the defects that copper flat wire bubbles are generated by high extrusion temperature and copper flat wire oil stain, scratches, copper powder, peeling and the like generated by drawing and high-temperature friction are fundamentally eliminated.
Description
Technical field
The utility model relates to finish rolling copper strap wire quantity-produced equipment after a kind of first drawing, belongs to transformer electromagnetic wire processing technique field.
Background technology
In recent years, along with the increasing of country to the power grid construction dynamics of investment, the processing strength and the comprehensive quality of producing product of electromagnetic wire processing enterprise at the high, precision and frontier product is more and more valued by high-power transformer producer.Copper conductor is the chief component of electromagnetic wire product, and the quality quality of copper conductor is to the normal decisive role whether of the operation of the quality of electromagnetic wire product quality and final transformer.The extruding of background technology, Wire Drawing mode have its intrinsic processing technology defective, such as the bubble of base silk, copper powder, greasy dirt and the extruding conductor of wire drawing conductor etc., increase production cost, influence product quality.
The utility model content
The utility model purpose provides finish rolling copper strap wire quantity-produced equipment after a kind of first drawing; Fundamentally eliminate the defectives such as copper strap wire greasy dirt, scuffing, copper powder, peeling of copper strap wire bubble that extruding high temperature produces and the generation of drawing high temperature friction; Reduce cost; Improve the quality of products, solve the problems referred to above that background technology exists.
The technical scheme of the utility model is: finish rolling copper strap wire quantity-produced equipment after a kind of first drawing; Comprise wire-drawing die, wire drawing tank body, copper cash, finishing roller, take-up axle; Copper cash is connected with the wire drawing tank body after passing wire-drawing die; The copper cash that the wire drawing tank body comes out gets into finishing roller, the copper cash that finishing roller comes out to take-up axle.
Wire-drawing die, wire drawing tank body, finishing roller, take-up axle are arranged by the front and back order successively.
Use the utility model, at first, before copper cash is rolling, increase by one prestretching and pull out program, again the copper bar after the drawing is carried out repeatedly finishing roller distortion in rolling, reach the electromagnetic wire of setting specification.
Processing step more specifically: raw material copper bar places on the pay off rack, drives down by force through circular wire-drawing die in the rotation of wire drawing tank body, and the copper rod area is compressed, and can remove the surperficial tiny flaw of copper cash base, and defective is washed away by the drawing process metalworking coolant; Through the too much group finishing roller roll forming of warp under traction drives of the copper bar after the drawing, obtain the copper strap wire of desired cross-sectional area shape and size at last, take-up to take-up axle.
The beneficial effect of the utility model: raw material copper rod area is compressed through after the drawing, makes it more near the sectional area of final copper strap wire, can reduce the roll live load like this, avoids local peak stress, prolongs roll campaign; The rolling of copper strap wire is a cold working process; Because the precision of roll is high; Intensity is big; Anti-wear performance is good, and the copper bar can reach desired cross-sectional area shape and size through plastic deformation under the active force of roll, and its processing technology has fundamentally been eliminated defectives such as the copper strap wire greasy dirt, scuffing, copper powder, peeling of copper strap wire bubble that extruding high temperature produces and the generation of drawing high temperature friction.
Description of drawings
Fig. 1 is the utility model embodiment sketch map;
Among the figure: wire-drawing die 1, wire drawing tank body 2, copper cash 3, finishing roller 4, take-up axle 5.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further through embodiment.
Finish rolling copper strap wire quantity-produced equipment after a kind of first drawing; Comprise wire-drawing die 1, wire drawing tank body 2, copper cash 3, finishing roller 4, take-up axle 5; Copper cash is connected with the wire drawing tank body after passing wire-drawing die; The copper cash that the wire drawing tank body comes out gets into finishing roller, the copper cash that finishing roller comes out to take-up axle.Wire-drawing die, wire drawing tank body, finishing roller, take-up axle are arranged by the front and back order successively.
Use technology: at first, before copper cash is rolling, increase by one prestretching and pull out program, again the copper bar after the drawing is carried out repeatedly finishing roller distortion in rolling, reach the electromagnetic wire of setting specification.
Processing step more specifically: raw material copper bar places on the pay off rack, drives down by force through circular wire-drawing die in the rotation of wire drawing tank body, and the copper rod area is compressed, and can remove the surperficial tiny flaw of copper cash base, and defective is washed away by the drawing process metalworking coolant; Through the too much group finishing roller roll forming of warp under traction drives of the copper bar after the drawing, obtain the copper strap wire of desired cross-sectional area shape and size at last, take-up to take-up axle.
Claims (1)
1. finish rolling copper strap wire quantity-produced equipment after the first drawing; It is characterized in that comprising wire-drawing die (1), wire drawing tank body (2), copper cash (3), finishing roller (4), take-up axle (5); Copper cash is connected with the wire drawing tank body after passing wire-drawing die; The copper cash that the wire drawing tank body comes out gets into finishing roller, the copper cash that finishing roller comes out to take-up axle.
