Heat treatment production line and heat treatment system

Abstract

The invention provides a heat treatment production line and a heat treatment system, and relates to the technical field of heat treatment equipment. The heat treatment production line comprises a wire collecting device, a wire unwinding device and a heat treatment furnace; a steel wire transversely penetrates through a hearth of the heat treatment furnace, and two ends thereof are respectively connected with the wire collecting device and the wire unwinding device; a speed adjusting mechanism is arranged between the wire collecting device and the heat treatment furnace; a tensioning device for applying tension to the steel wire is arranged between the heat treatment furnace and the wire unwinding device; the tensioning device comprises a first support roller and a second support roller for flatly supporting the steel wire; a pulley is arranged between the first support roller and the second support roller, and is arranged on the steel wire; and the pulley is connected with a counterweight block. The heat treatment system comprises the heat treatment production line, and has the advantages of capability of satisfying multi-specification batch production, simple operation, safety, energy conservation, environmental protection and practicability.

Description

technical field [0001] The invention relates to the technical field of heat treatment equipment, in particular to a heat treatment production line and a heat treatment system. Background technique [0002] Heat treatment is an important link in the production process of steel wire. There are three purposes of heat treatment of steel wire: one: to obtain a uniform composition and a structure suitable for cold working; two: to eliminate work hardening and internal stress in order to continue cold working; three: to obtain the required Mechanical properties, process properties and physical properties. [0003] The prior art has the following disadvantages: [0004] ⑴In order to increase production capacity, the current heat treatment production line is equipped with more than 2 speed-controlled tractors to meet the same batch of multi-specification production, but the tension traction can only be used for the same specification. Due to various factors, it is impossible to set ...

AI Technical Summary

Problems solved by technology

[0004] ⑴In order to increase production capacity, the current heat treatment production line is equipped with more than 2 speed-controlled tractors to meet the same batch of multi-specification production, but the tension traction can only be used for the same specification. Due to various factors, it is impossible to set multiple tensions in the production line traction, so there are limitations

[0005] ⑵It is difficult to set up the traction synchronization process. If the tension traction speed is too slow, the diameter of the batch steel wire will be thinned, and the tension effect will not be achieved if the speed is too fast.

At the same time, if the operator makes a mistake in operating the tension traction or the tension traction fails due to electrical appliances, machinery and other parts, it will cause batches of steel wires to be scrapped or broken, so a mistake or failure will cause serious economic losses;

[0006] (3) Tension traction consumes a lot of power, increases production costs, and is inconvenient for employees to operate, and there are unsafe factors. For example, two people must cooperate in the operation process, and the traction must be operated in a rotating state
