Embodiment Construction

[0018] Below in conjunction with accompanying drawing, the present invention is described in detail:

[0019] The invention provides a power control device for intelligent annealing, such as figure 1 , 2 As shown, it includes an annealing power supply control unit 10 that is connected to a three-phase alternating current power supply and converts the three-phase alternating current into a single-phase alternating current, a transformer 20 connected to the output end of the annealing power supply control unit 10, and a capacitor 30 connected to the transformer 20, with An auxiliary unit 40 with a conductive wheel 60 and a voltage feedback card 50 forming a loop with the annealing power supply control unit.

[0020] Annealing is a metal heat treatment process that heats the metal to a certain temperature for a period of time, so that its various indicators can reach the standard. According to the law of energy conservation, it is known that to make the resistance generate heat,...

Abstract

The invention relates to the field of control equipment for the production process of metal wires for annealing, in particular to an intelligently-annealing power source control device. Three-phase alternating current is changed into single-phase alternating current which is output to conductive wheels; the single-phase alternating current is subjected to the transformation of a transformer and the filter of a filter capacitive circuit and then is fed to two contacted conductive wheels for realizing single-phase alternating current annealing on drawing metal wires, thereby not only simplifying system modules and greatly reducing the cost, but also improving the accuracy of voltage control; the production efficiency is improved by improving the cost performance; a high-precision annealing power source control unit outputs the voltage, so that the invention saves energy consumption, is beneficial to function completion and convenient use and maintenance of the whole annealing equipment and ensures the safety and the stability of the system.

Description

【Technical field】 [0001] The invention relates to the field of production process control equipment for annealing metal wires, in particular to a power control device for intelligent annealing. 【Background technique】 [0002] The wire drawing machine is a commonly used wire and cable production equipment. It uses the easy stretchability of the metal wire to draw the metal wire with a thick diameter into a slender wire through a number of die sets in a certain ratio. It is widely used in Production of copper, iron, steel, alloys, etc. [0003] At present, in the production operations of cable factories, copper factories, aluminum factories, etc., wire drawing, annealing, drying, and wire collection of metal wires are indispensable processes. Since metal wires such as copper wires and aluminum wires are prone to hardening during the wire drawing and stretching process, the annealing process is generally performed after the wire drawing process. The early annealing method was...
