Embodiment Construction

[0007] Such as figure 1 As shown, a differential speed mesh belt tempering furnace consists of a tempering furnace body (1), a heating section (2), a thermocouple (3), a circulating fan (4), a main sprocket (5), and a main chain mesh belt (6), baffle plate (7), secondary sprocket wheel (8), secondary chain mesh belt (9), transmission system (10), feed table (11) form.

[0008] Two main chain mesh belts (6), main sprocket wheel (5) and baffle plate (7) form a loop, and the secondary chain mesh belt (9) and secondary sprocket wheel (8) form a loop, and the secondary chain mesh belt is located at the two In the middle of the main chain mesh belt (such as figure 2 shown); the middle part of the rod-shaped tempering piece is placed on the secondary chain mesh belt, and the two ends are separated by the baffle of the main mesh belt; the transmission system (10) is connected with the main sprocket (5) and controls the tempering piece in the furnace The passing speed; the main spro...

Abstract

The invention discloses a differential mesh belt type tempering furnace which comprises a tempering furnace body, a heating section, a feeding table, primary chain mesh belts, primary chain wheels, baffles, a secondary chain mesh belt, secondary chain wheels and a transmission system. The primary chain mesh belts, the primary chain wheels and the baffles form an operating loop. The secondary chain mesh belt and the secondary chain wheels form operating loop. The middle of a bar-shaped tempering part is placed on the secondary chain mesh belt. The two ends of the bar-shaped tempering part are separated by the baffles on the primary chain mesh belts. The diameters of the main chain wheels are larger than those of the secondary chain wheels. The operating speeds of the primary chain mesh belts are lower than that of the secondary chain mesh belt. The speed difference realizes the automatic turning of the tempering part in the tempering furnace, the heat treatment quality of the tempering part can be improved greatly, and the special design of the feeding table can realize the feeding automation.

Description

Technical field: [0001] The invention relates to a tempering treatment device for metal parts after quenching. The tempering parts are automatically turned to improve the quality of tempering treatment, which belongs to the field of mechanical heat treatment. Background technique: [0002] Piston rod is the main part of automobile and high-speed train shock absorber. In order to improve the quality of metal processing and prevent deformation and cracking of quenched metal parts, tempering treatment is usually required. Tempering is a process of heating quenched steel below the austenite transformation temperature, and cooling after holding for a period of time, which requires high temperature control. In the prior art, for the tempering treatment of metal parts after quenching, whether it is a box-type tempering furnace or a belt-type tempering furnace, although a hot air circulation system is added, the tempered parts are not automatically turned, and uniform heating cannot...
