Abstract

The invention discloses a piston rod lug ring welding process. The piston rod lug ring welding process disclosed by the invention comprises the steps of cleaning a piston rod lug ring and a piston rodbody; clamping a piston rod and a lug ring for rotary pressure welding; and cooling and polishing a weld joint and detecting a welding area. According to the piston rod lug ring welding process, thepiston rod and the piston rod lug ring are preheated in the friction welding process; the welding efficiency is improved; and the piston rod produced by the process has the characteristics of high welding efficiency and high quality stability.

Description

technical field [0001] The invention relates to the technical field of piston rods, in particular to a welding process of a piston rod earring. Background technique [0002] The piston rod is the connecting part that supports the work of the piston. It is mainly used in the oil cylinder or air cylinder. It has a strong sealing property and is a part that needs to be moved frequently in the oil cylinder or air cylinder. The long-term reciprocating motion of the piston rod will inevitably lead to It puts forward certain requirements for its own strength, so it puts forward higher requirements for the strength and quality of the welding on the piston rod. [0003] The piston rod earring is mainly a connecting part that the piston rod transmits its motion to other devices. The piston rod earring is connected to other devices and needs to carry a large force and torque during the movement process. In the prior art, the piston rod and the piston rod earring They are usually conne...
