Abstract
A method for connecting a square shaft with a swing arm comprises the square shaft and the swing arm and is characterized in that a heightened special punch press is used, a punching die is used for punching, so that a metal material of the swing arm is extruded, and a bulge on the periphery of a hole above the swing arm wraps the square shaft tightly, so that the square shaft and the swing arm are connected into a whole.
Description
Technical Field
The invention relates to the field of manufacturing of air conditioner valve parts, in particular to the field of manufacturing of valve plate control parts for air conditioner valves.
Background
The square shaft one end that air conditioner valve used installs the back in the square hole between the valve block, with the copper sheathing supporting square shaft who adorns at the valve frame, the swing arm is equipped with to the square shaft other end, and the swing arm is connected with the square shaft, and the swing arm welds on the square shaft, and the welding work volume is big and the quality is not too reliable, just can influence the valve and start the performance if the welding is insecure.
Disclosure of Invention
The invention aims to overcome the defects, simplify the manufacturing process and improve the reliability.
A method for connecting a square shaft with a swing arm comprises the steps of forming the square shaft and the swing arm, and is characterized in that a metal material of the swing arm is extruded through stamping, and a bulge on the periphery of a hole above the swing arm wraps the square shaft tightly.
