Technical Field

The invention belongs to the technical field of bimetal composite material equipment, and particularly relates to a movable device of a copper-aluminum composite bar crawler drawing die.

Background

Along with the increasing importance of energy conservation and environmental protection in the world, the requirement is higher and higher, the application of the copper-aluminum composite bar is increasingly expanded, the capacity is more and more obviously deficient, and the low drawing capacity is mainly focused on; in order to solve the problem of low drawing efficiency, a series of improvement is carried out, finally, copper pipe crawler drawing equipment is successfully transformed and applied to the drawing production of a copper-aluminum composite row, the production efficiency is greatly improved, but the defect is that the transformed crawler drawing equipment cannot produce a six-meter fixed-length finished row, and because the straightness of the produced row does not meet the requirement, the last procedure can only be transferred to hydraulic drawing with low productivity, so that the straightness of materials is ensured, and the yield of the crawler drawing process is severely restricted; meanwhile, the existing caterpillar band is fixed in drawing and the mould, the distance is only 600mm, the copper-aluminum composite row can generate unstable transverse fluctuation on the caterpillar band, and the unstable influence on the deformation stress of materials in the mould is serious.

Disclosure of Invention

The invention provides a movable device of a copper-aluminum composite bar crawler drawing die, which solves the problem of straightness of a finished bar of six meters at last in crawler drawing in the background technology.

The technical scheme of the invention is realized as follows: copper aluminium composite row track drawing die movable device, including the track drawing machine, be equipped with straightener and supplied material guider on the same water flat line in track drawing machine right side, track drawing machine right side is equipped with drawing die, the drawing die below is equipped with the mould support, the frame fixed connection of mould support front end and track drawing machine, mould support top both sides respectively are equipped with the slide rail, and the drawing die lower extreme is located the slide rail, and drawing die can follow the slide rail and slide around, and the drawing die below is equipped with the connecting plate, and the connecting plate links to each other with the hydro-cylinder piston rod in the mould hydro-cylinder, and the rear end of mould support is located to the mould hydro-cylinder, the frame upper end of track drawing machine is equipped with the cylinder fixing base, is equipped with the cylinder on the cylinder fixing base, and the cylinder below.

The invention has the beneficial effects that: the distance between the mold and the crawler belt is increased by geometric times through the movable structure, the geometric factors are improved by the elongated distance, the change can cause the same geometric change generated by the same stress, and the influence on the stress generated by the material is reduced by multiple times, so that the purpose of reducing the deformation is achieved; the guide rollers are arranged to prevent the geometric change generated by the drawing stress of the crawler belt from being transmitted to the die, so that the stress change of the material in the die shaping area is further improved, and the material is more stably molded. The invention solves the problem of unstable and unqualified straightness of continuous drawing of the copper-aluminum composite bar by minor modification and lower cost, thereby realizing the process stability of cutting off finished products by continuous drawing of the copper-aluminum composite bar, eliminating the hydraulic drawing with low efficiency in the last procedure and greatly improving the production efficiency.

Detailed Description

For a better understanding and appreciation of the invention, it will be further described in connection with the accompanying drawings: a movable device of a copper-aluminum composite row track drawing die comprises a track drawing machine 1, wherein a straightening machine 3 and a supplied material guiding device 4 are arranged on the same horizontal line on the right side of the track drawing machine 1, a drawing die 2 is arranged on the right side of the track drawing machine 1, a die support 11 is arranged below the drawing die 2, the front end of the die support 11 is fixedly connected with a frame 14 of the track drawing machine 1, slide rails 10 are respectively arranged on two sides above the die support 11, the lower end of the drawing die 2 is positioned in the slide rails 10, the drawing die 2 can slide back and forth along the slide rails 10, a connecting plate 13 is arranged below the drawing die 2, the connecting plate 13 is connected with a cylinder piston rod 15 in a die cylinder 6, the die cylinder 6 is arranged at the rear end of the die support 11, a cylinder fixing seat 12 is arranged at the upper end of the frame 14 of the track drawing machine 1, a cylinder 7 is arranged on the cylinder, the distance between the two guide rollers 9 can be adjusted by means of an adjusting handwheel 8.

Specifically, before drawing, one end of a track composite material 5 enters a drawing die 2 through a feeding guide device 4 and a straightening machine 3, the drawing die 2 enters a track drawing machine 1 from the drawing die, before drawing, the distance L1 between a discharge port of the drawing die 2 and a track 16 of the track drawing machine 1 is 600mm, after adjustment, the drawing die 2 is driven by a die oil cylinder 6 to move rightwards along a slide rail 10 to move to a position where the distance L2 between the discharge port of the drawing die 2 and the track 16 of the track drawing machine 1 is 1950mm, an air cylinder 7 drives two guide rollers 9 to move downwards, the two guide rollers 9 move to two sides of the track composite material 5, the distance between the two guide rollers 9 is suitable for the width of the track composite material 5 through adjusting a hand wheel 8, at the moment, the straightening machine 3 starts to correct, the straightened track composite material 5 moves leftwards and moves into the drawing die 5 for drawing, and the drawn crawler belt composite material 5 is subjected to discharge size sawing through the crawler belt drawing machine 1.

The distance between the improved drawing die and the crawler belt is increased in geometric multiple, and can be moved to 1950mm from 600mm, so that the influence caused by the fluctuation of the copper-aluminum composite row on the crawler belt is reduced; the difficulty of drawing the mould that brings of lengthening of distance, in order not to increase the mould degree of difficulty of drawing, with the design of mould position for portable, can keep mould initial position unchangeable like this, remain original mould mechanism of drawing and do not increase the mould degree of difficulty. The oil cylinder drives the die to move back and forth on the rail, so that the movable target of the die can be realized. Meanwhile, a guide roller is added, after the die is moved to a long distance, the guide roller is driven by an air cylinder to move to a set proper guide position, and a hand wheel is adjusted to adapt to the width of the material. The device effectively limits the transverse displacement of the material, plays a certain role in stopping the transverse fluctuation conduction of the copper-aluminum composite bar, and reduces the influence of the transverse fluctuation conduction on the deformation stress of the material.
