Heat treatment furnace

Abstract

The invention discloses a heat treatment furnace and belongs to the technical field of furnace facilities. The heat treatment furnace comprises 1, a furnace support, 2, a furnace body arranged on the furnace support, wherein bottoms of two sides of the hearth of the furnace body are provided with grooves concaved downward; workpiece supports are respectively fixed to the grooves in a length direction; and bottoms of the grooves are provided with a group of support pillar receiving chambers, 3, a frame corresponding to the bottom of the furnace body, 4, a tractor elevator mechanism installed on an upper part of the frame, 5, a tractor guide rail support fixedly connected to the tractor elevator mechanism, 6, a tractor arranged on the tractor guide rail support, wherein a group of support pillars are fixed to two sides of the tractor in a length direction; the support pillars stretch into the support pillar receiving chambers; workpiece consignment mechanisms are fixed to upper parts of the support pillars; and the workpiece consignment mechanisms are located in the grooves, and 7, a tractor reciprocating motion mechanism arranged on the frame and connected to the tractor. The heat treatment furnace realizes stepping movement of a workpiece, satisfies workpiece stepping movement requirements, has a simple overall structure and is convenient for manufacture, installation, use and maintenance.

Description

technical field [0001] The invention belongs to the technical field of furnace facilities, in particular to a heat treatment furnace . Background technique [0002] As known in the industry, in the manufacturing process of mechanical parts (such as chain rails) and metal materials (such as bars, pipes and forgings) made of metal, heat treatment is usually required to ensure quality such as improving hardness. Usually, the workpiece for heat treatment is fed into the furnace from the feed port at one end of the length direction of the heat treatment furnace, and the workpiece is moved towards the other end of the length direction of the heat treatment furnace by the driving mechanism within a period of time set according to the process. The discharge port at one end moves until it is output from the discharge port to complete the heat treatment.

Problems solved by technology

[0004] Not limited to the patents or patent application schemes listed above, the common point is that the feeding mechanism for driving the workpiece to move is set in the furnace, so the short service life and troublesome maintenance are common shortcomings, and the utility model patent authorization announcement The "vacuum annealing furnace feeding mechanism" disclosed by No. CN20181706U may be able to avoid the above-mentioned shortcomings, but the overall structure is complicated and it is lacking, and because the patent scheme does not provide such as the power mechanism that drives the traction trolley, the relationship between the feeding trolley and the traction trolley The enlightenment of technical elements such as the structural connection relationship between the guide rail and the guide rail in the furnace body, etc., so there are obstacles to the interpretation of the industry
