Abstract

The utility model discloses an aluminum wire die drawing heat yoke which comprises a die body, wherein a wire drawing chamber and a die drawing chamber are arranged on the die body; a spiral cooling chamber is formed around the wire drawing chamber; the wire drawing chamber and the die drawing chamber are both a hole with taper; the periphery of the die body is coated with a heat insulating layer; supporting blocks are arranged on two sides of the die body; the die body is located on the supporting blocks by use of bolts. By adopting a heat yoke method, aluminum wires are thermally treated on line by virtue of heat generated when an aluminum rod is cooled, thus an in-furnace heating step of the aluminum wires is saved, the energy is saved, the production efficiency is improved and the production cost is lowered.

Description

An aluminum wire draft thermal yoke

technical field

The utility model relates to an aluminum wire drafting thermal yoke.

Background technique

In the process of preparing aluminum wire in the factory, it needs to go through multiple processes such as smelting, pouring aluminum ingots, heat treatment, aluminum rod making, reheat treatment, wire drawing, and so on. Among them, in order to promote the phase transformation and refine the crystal grains, forced cooling with water and other media is required. A large amount of heat is wasted through water and other media during forced cooling, and a large amount of energy is needed to be heated again during heat treatment of aluminum wire, which leads to large energy consumption, long production cycle, low production efficiency and high production cost.

Utility model content

The technical problem to be solved by the utility model is to provide an aluminum wire draft thermal yoke with simple structure, convenient use, energy saving and production efficiency improvement.

In order to solve the above-mentioned technical problems, the technical solution adopted by the utility model is: a kind of aluminum wire drawing die thermal yoke, it is characterized in that: it comprises a mold body, and described mold body is provided with drawing cavity and drawing cavity, so A spiral cooling chamber is arranged around the wire drawing chamber, both the wire drawing chamber and the mold drawing chamber are taper holes, the periphery of the mold body is wrapped with an insulating layer, and support blocks are arranged on both sides of the mold body, so The mold body is positioned on the support block by means of bolts.

The working principle of this new type is as follows:

The solidified aluminum rod passes through the draft cavity and is extruded to become thinner, and at the same time, it transfers heat to the mold body and then cools itself. After the mold body absorbs the heat of the aluminum heating rod, the temperature of the wire drawing chamber rises through heat conduction and heat storage. The aluminum wire that needs to be heated by heat treatment is heated through the wire drawing chamber, and at the same time, it is extruded by the wall of the chamber and becomes thinner. In this way, the two cavities on the mold body realize two processing processes of cooling and heating. The function of the insulation layer is to reduce the heat loss of the mold body to the air and increase the temperature of the wire drawing cavity. The function of the spiral cooling chamber is to adjust the temperature of the wire drawing chamber. When the temperature is too high, a cold medium is passed into the spiral cooling chamber to cool down. The effect of fixing screw and fixed support block is to prevent the mold body from moving under the effect of pulling force.

The beneficial effects produced by adopting the above technical scheme are: the utility model adopts the hot yoke method to use the heat cooled by the aluminum rod to carry out on-line heat treatment on the aluminum wire, which saves the heating link in the aluminum wire furnace, saves energy, improves production efficiency, and reduces production costs. cost.
