Embodiment 1

[0016] The heat treatment method of the transmission metal chain of this embodiment includes the following steps:

[0017] A. Carburizing treatment: Put each component of the transmission metal chain into a carburizing furnace for carburizing treatment. The carburizing temperature is 750°C, the carburizing time is 50 minutes, and the carburizing time reaches 20 minutes, and an exhaust gas operation is performed; The fire temperature is 360℃, and the tempering time is 40 minutes. After the furnace is air-cooled, the parts are taken out of the carburizing furnace for surface cleaning;

[0018] B. Quenching: Take two heating furnaces marked (1) and (2), preheat the temperature of the two heating furnaces to 900℃ and 830℃ respectively, discharge the exhaust gas in the heating furnace, and then discharge the outside The chain plates and inner chain plates are placed in the heating furnace (1), and the heating furnace (1) is heated to 920°C for 80 minutes, and then the outer and inner ch...

Abstract

The invention discloses a heat treatment method for a transmission metal chain, which relates to the technical field of chains; it includes the following steps: A. Carburizing treatment: each component of the transmission metal chain is put into a carburizing furnace for carburizing treatment, and the carburizing temperature is 750 ℃ ​​~ 800 ℃, carburizing time 50 minutes ~ 70 minutes, tempering temperature 360 ​​℃ ~ 400 ℃, tempering time 40 minutes ~ 50 minutes; B, quenching: put each part of the transmission metal chain into two heating Oil cooling after heating in the furnace; C. Tempering: Temper and heat all parts at medium temperature and then air cool with the furnace. Compared with the prior art, the present invention can solve the problem in the prior art that parts are easily damaged when heat treatment is performed to improve the wear resistance of the transmission metal chain.

Description

Technical field [0001] The invention relates to the technical field of chains, in particular to a heat treatment method for transmission metal chains. Background technique [0002] In the field of mechanical transmission, the use of metal chains for transmission is very common. The basic structure of the transmission metal chain is that many chain link units of the same structure are connected end to end in the form of hinge pairs. Each part of the chain link unit includes two sets of oppositely arranged and The outer chain plate and the inner chain plate are connected by a pin, a sleeve is arranged between the two opposite inner chain plates, and the sleeve is sleeved with rollers. This structural feature enables the chain to have high strength and The chain can be flexibly changed in the specified direction, so that the chain can be widely used in agriculture, textiles, geological product mining, construction and automobile industries, covering a wide range of applications; but...
