Problems solved by technology

[0005] In order to make up for the deficiencies of the prior art, the present invention proposes a steel wire quenching process. The present invention is mainly used to solve the problem that the existing steel wire is usually in a static heating mode when it is quenched. This heating method is easy to make the inside and surface of the steel wire Inhomogeneous heating leads to large differences in the performance of the steel wire after quenching; and the cooling efficiency of the cooling medium is low when cooling the steel wire

Embodiment Construction

[0029] use Figure 1-Figure 5 A steel wire quenching process according to an embodiment of the present invention is described as follows.

[0030] like Figure 1-Figure 5 Shown, a kind of steel wire quenching process of the present invention, this process comprises the following steps;

[0031] S1: Cutting: the steel wire is fed into the cutting machine by means of roller feeding and cut into uniform steel wire segments;

[0032] S2: Feeding: Send the steel wire segment cut into uniformity into the feeding device 4 provided on the quenching box 1 through the feeding replacement device 3;

[0033] S3: Quenching: The steel wire section is transported to the quenching bin 11 set in the quenching box 1 through the conveyor belt 42 and the elastic fastening belt 44 of the feeding device 4 for quenching, and then the quenching bin 11 is heated to 830°C-870°C and Keep it for 0.5-2.5 hours, cook the steel wire in the whole furnace, and the time for taking out the furnace is 0.3-0.5...

Abstract

The invention belongs to the technical field of steel wire quenching, specifically a steel wire quenching process; a quenching chamber is provided inside the quenching box; the cooling chamber is filled with cooling medium, and the bottom of the cooling chamber is connected with the quenching chamber through a heating tube; A condensate pool is set above the condensate pool, and the interior of the condensate pool is filled with condensed gas; the inside of the push box is slid with a sliding material guide plate through a telescopic rod, and a hollow guide rod is set on the sliding material guide plate; the end of the hollow guide rod slides It is arranged in the guide slide hole, and the end of the hollow guide rod is provided with a guide push head; the feeding roller is evenly arranged on the outer wall of the quenching box through the support frame; the conveyor belt is rotated and arranged on the outer wall of the feeding roller, and the conveyor belt There are multiple elastic fastening belts evenly connected by elastic connecting blocks; it can make the steel wire section shake in the quenching box, thereby increasing the effect that the steel wire section changes from static to dynamic during the quenching process, and further increases the quenching of the steel wire section. Effect.

Description

technical field [0001] The invention belongs to the technical field of steel wire quenching, in particular to a steel wire quenching process. Background technique [0002] Steel wire is one of the four types of steel plate, tube, type and wire. It is a reprocessed product made of hot-rolled wire rod through cold drawing. In the production process of steel wire, in order to improve the mechanical properties of steel wire, steel wire is usually Hardening treatment is carried out to greatly improve the strength, hardness, wear resistance, fatigue strength and toughness of steel wire, so as to meet the different needs of various mechanical parts and tools. [0003] Steel wire occupies a very important position in the national economy, and steel wire quenching heat treatment is a very important process in the production process of steel wire. There are many methods of steel wire quenching and heat treatment, and the method of quenching in hot-melt lead with muffle furnace heatin...
