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, and in particular relates 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

[0003] The "push rod type continuous vacuum tempering and annealing multi-purpose furnace" introduced by the Chinese invention patent publication number CN101333591A is to use the push rod to push the workpiece from the feed port of the heat treatment furnace Move towards the direction of the discharge port until it is expelled from the furnace. Since the patent application does not provide any schematic diagram, the specific structure cannot be known; the "high-frequency annealing machine positioning feeding mechanism" recommended by CN201284351Y uses a synchronous belt transmission mechanism to drive the workpiece , because the synchronous belt moving mechanism is located in the furnace, it is not only easy to damage, but also troublesome to maintain; the "quenching equipment" disclosed by the publication number CN101144112A utilizes the principle of a forklift to shovel out the workpiece after heat treatment from the furnace and transfer it to the quenching pool. The accompanying drawings of the description of the patent scheme illustrate the rollers arranged in the furnace to drive the workpiece to move; the "seamless steel pipe quenching furnace transmission device" provided by CN201614391U utilizes the transmission roller to drive the steel pipe

[0004] is 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 service life Short, troublesome maintenance is a common shortcoming, and the "vacuum annealing furnace feeding mechanism" disclosed by the utility model patent authorization announcement number CN20181706U may be able to avoid the shortcoming, but the overall structure is complicated and it is lacking, and because the patent scheme does not provide such The enlightenment of technical elements such as the power mechanism that drives the traction trolley, the structural connection relationship between the feeding trolley and the traction trolley, and the docking of the guide rail and the guide rail in the furnace body, so there are obstacles to the interpretation of the industry
