Research on High-frequency Forging Forming Equipment of Steel Pipe Ends
This paper introduces the process and technical equipment of heading for cold-drawn steel pipes,analyzes the technological innovation characteristics of the heading unit equipment,which believes that the core technology and core mechanism of the equipment is the segmented and tilted hammer head,which improves the stress of the driving spindle bearing,reduces the contact stress of the spherical support of the hammer arm,realizes the smooth radial forging of the steel pipe ends with high frequency of 500 times/min,and can realize stepless speed regulation,the production speed is increased by more than 1 time,and the product yield reaches 98%,which improves the working life of the whole machine.
