Description
Technical Field
The utility model relates to a mold design makes the field, especially relates to an environmental protection and energy saving special-shaped copper single line drawing die utensil.
Background
In cable manufacturing enterprises, copper single wires are often made into "fan-shaped" or "trapezoid" shaped single-wire conductors in order to improve the filling system of the cable. At present, a special-shaped monofilament conductor is usually produced by adopting a drawing die, and the lubricating effect in the drawing process is usually enhanced in production by firstly passing through a box body filled with lubricating powder before a copper single wire enters the drawing die, so that a certain amount of lubricating powder can be attached to the surface of the copper single wire to play a lubricating effect in the drawing process of the copper single wire, but the lubricating powder attached to the surface of the copper single wire is easy to fall off and is not environment-friendly, and the lubricating effect in the drawing process is poor.
In addition, when the drawing die is used, the shaping section of the drawing die is worn most, the drawing die is of an integral structure at present, if the precision is insufficient due to abrasion, the drawing die needs to be integrally replaced, the cost is increased, and waste is caused.
SUMMERY OF THE UTILITY MODEL
In order to overcome the defects, the utility model provides an environmental protection and energy saving special-shaped copper single line drawing die.
In order to realize the purpose, the technical scheme of the utility model is that: the utility model provides an environmental protection and energy saving dysmorphism copper single line drawing mould, drawing mould includes entry section, deformation section, design section and export section in proper order, the length ratio of entry section, deformation section, design section and export section is 2 in proper order 4: 2: 2; the inlet section and the deformation section are of an integral structure, and the shaping section and the outlet section are of an integral structure; the integrated structure of the inlet section and the deformation section is connected with the integrated structure of the shaping section and the outlet section through a plurality of countersunk head bolts in a fastening way and connected through two pins which are not centrosymmetric; the inlet of the inlet section is coaxially provided with an annular fixing block, and the inner wall of the fixing block is provided with an annular groove.
Preferably, the horizontal included angle of the inlet section is 50 degrees, and the horizontal included angle of the deformation section is 30 degrees.
Preferably, the inlet section and the deformation section are both arc-surface-shaped in inner profile section.
The utility model has the advantages that: 1. the inlet section and the deformation section are detachably connected with the shaping section and the outlet section in a split manner, so that the shaping section is convenient to maintain or replace after being worn. 2. The inlet section is equipped with the annular groove, can collect the lubricated powder that drops, helps the environmental protection health of site environment, can also continuously lubricate the copper single line. 3. The length proportion of the inlet section, the deformation section, the shaping section and the outlet section is 2:4 in sequence: 2: 2, the ratio can effectively reduce the stretch-break rate and the wear rate to the shaping segment.
