Benefits of technology

This patented technology helps prevent damage caused by water or other substances during manufacturing processes used on drive axles such as those found inside them. It involves adding certain elements like molybdenum (M) into an alloy called iron-based material made from chrome carboxylate solution through casting techniques. These added materials help protect against rusting due to acidic environments commonly present along with road traffic. Additionally, this method allows for efficient use of raw metal while maintain its quality over time without losing their original qualities. Overall, these technical features make castings stronger and more durable compared to traditional methods.

Problems solved by technology

This technical problem addressed by this patented technology relates to improving the efficiency and effectiveness of producing high-quality parts from cast iron (drive shaft lift cylinder) without causing damage or wear out other components due to excessive heat generated at certain areas within these parts' interior.

Embodiment 1

[0016] A forging process method for a drive axle hoisting oil cylinder, comprising the following steps:

[0017] a) Casting a steel ingot with the following alloy composition by weight: C0.47%, Si1.37%, Mg0.85%, P0.05%, S0.015%, Cr1.85%, Mo0.78%, Ti0.85 %, the balance is Fe;

[0018] b) Forging process: 1) Use the air hammer to pull out the hammer at the bottom of the oil cylinder, the number of times is 6; Finished length dimension of long oil cylinder;

[0019] c) For the forged oil cylinder forgings, there is a machining allowance of 9 mm for the outer diameter and inner diameter, and then rough machining, finishing machining, and deburring are performed;

[0020] d) Put the machined oil cylinder in a controlled-atmosphere box-type carburizing furnace, and carburize for 13 hours under the atmosphere with a carbon potential of 1.6% and a temperature of 325°C.

Abstract

The invention discloses a forging method for a drive axle lifting oil cylinder. The forging method comprises the following steps: a) preparing and casting a steel ingot with the following alloy components in percentage by weight: greater than or equal to 0.32% but less than or equal to 0.42% of C, greater than or equal to 0.26% but less than or equal to 0.32% of Si, greater than or equal to 0.24% but less than or equal to 0.45% of Mn, greater than or equal to 0.08% but less than or equal to 0.18% of P, greater than or equal to trace amount but less than or equal to 0.025% of S, greater than or equal to 0.35% but less than or equal to 0.48% of Cr, greater than or equal to 0.33% but less than or equal to 0.44% of Mo, greater than or equal to 0.65% but less than or equal to 1.30% of Ti, greater than or equal to 0.08% but less than or equal to 0.20% of Sn, and the balance Fe. The forging method is convenient in blank forming, high in efficiency and easy in forging forming; the forged drive axle lifting oil cylinder is good in strength, long in service life, safe and reliable, and suitable for mass forging production of drive axle lifting oil cylinders of various models.
