Description

Laminated wire drawing machine

Technical Field

The invention relates to a production device of a cable conductor wire, in particular to a large drawing machine of the cable conductor wire.

Background

The large drawing machine for cable conductor wires is a metal drawing device for drawing and extending the cable conductors made of copper, aluminum and other materials with the diameter of more than 8 mm, the processing mode is to adopt a plurality of drawing wheels which are arranged in sequence from front to back and have different rotation speeds which are gradually accelerated and a drawing die between two adjacent drawing wheels to gradually draw the wires, the diameter of the wires processed by the large drawing machine is large, the required drawing force is also large, and the drawing wheels need larger diameter in order to ensure that the wires cannot be torn and damaged due to small bending curvature radius when the wires repeatedly pass the surfaces of the drawing wheels for a plurality of times in the processing process, so that the rotation speed of the drawing wheels close to the input side of the wires is lower, and on the premise of ensuring the required drawing force, a driving motor can meet the requirements of low speed and high torque, so that the cost of the motor is high; and under the condition that the diameter of the wire drawing wheel is larger, the wire drawing wheels are sequentially arranged front and back, so that the wire drawing machine is longer in length and size, large in occupied area, long in path for operation, maintenance and inspection of operators in the using process of the equipment, high in labor intensity and high in manufacturing cost and using cost. The wire drawing machine body is a basic supporting structural member of the wire drawing machine, the wire drawing machine body with a conventional structure is a box-type structure formed by welding a front side wall plate, a rear side wall plate, a left end wall plate, a right end wall plate and a bottom plate, the thickness of a supporting part of a wire drawing wheel shaft is increased through a flange to form a wire drawing wheel shaft supporting hole to meet the installation requirements of a supporting bearing and a sealing element, the flange is connected with the front side plate and the rear side plate in a welding mode, the flange is only welded with the front side plate and the rear side plate along the periphery of the flange, the connecting strength of the flange cannot meet the supporting requirements of the wire drawing wheel shaft frequently for the flange forming the wire drawing wheel shaft supporting hole to support the wire drawing wheel shaft, particularly for a large wire drawing machine, the stress is larger in the wire drawing process, the existing problems are more obvious, in the wire drawing machine, the wire drawing wheel shaft and the side wall of the wire, the flange is difficult to position during welding, and the machining of the wire drawing wheel shaft supporting hole after the flange is welded is also eccentric frequently, which brings inconvenience to the machining and manufacturing of the wire drawing machine body. During the drawing process, a large amount of heat is generated and a small amount of powder is extruded from the wire rod, so that the wire drawing wheel must be cooled and cleaned in the drawing machine, and the wire rod to be drawn must be lubricated with the wire drawing die. In a large drawing machine, wire drawing wheels are soaked or semi-soaked in drawing oil, the wire drawing wheels which are arranged in a line are positioned in the drawing oil, and the wire drawing wheels and drawn wires wound on the wire drawing wheels can be subjected to heat dissipation and cleaning by means of the drawing oil, but the wire drawing oil soaked in the wire drawing wheels can continuously absorb heat generated in the wire drawing process and raise the temperature in the working process, so that the heat dissipation effect of the wire drawing wheels is poor, the powder cleaning effect of extruded wires in the wire drawing process is not good, and the extruded powder can abrade a wire drawing die; in addition, if the wire drawing wheels are not arranged in a row, the wire drawing oil is difficult to soak and dissipate heat of each wire drawing wheel; for the constant-speed wire drawing wheel positioned outside the output rotary die, immersion cooling is not possible, other external cooling means are difficult to adopt, the cooling is difficult to implement, and the operation of the wire drawing machine is extremely unfavorable. After the wire is stretched, the surface of the wire inevitably causes the deterioration of the surface roughness due to the abrasion of each wire drawing die, the appearance is poor, the fine grinding marks are seriously generated on the cable conductor, the local part of the cable conductor is easy to generate stress concentration, the cable conductor is easy to fold in the using process and hidden troubles are brought to the cable, the roughness deterioration of the surface of the cable conductor can be improved by adopting the output end wire drawing die with the rotating function, the surface of the cable becomes smooth and clean under the rotating extrusion action of the rotating wire drawing die, the surface of the cable is more beautiful, and the cable is safer and more reliable in the using process; the core of the wire-drawing die with the rotatable output end of the existing wire-drawing machine is inserted on the rotatable die sleeve to form rigid connection, and in the using process, due to errors of processing and assembling, the axis of the core is likely to form a cross state with the path of the wire to be drawn, so that the path of the wire to be drawn is bent at the output wire-drawing die, and thus when the core rotates, additional radial force is generated between the wire to be drawn and the core, the core is subjected to additional abrasion, and the improvement of the surface quality of the wire is not facilitated; in addition, the mold core is not easy to be taken out after being rigidly inserted on the mold sleeve, which is very inconvenient for the mold changing operation or the cleaning operation of the mold core.
