AI Technical Summary
Technical Problem
The existing plug-in flexible interface steel pipe has low molding quality and high defect rate, especially in small-diameter steel pipes, which are prone to cracking and damage, affecting the sealing effect and service life.
Method used
The end of the steel pipe is heated and stamped with a stamping device, and then the end is straightened by a flat port device, and then the molding device is used to mold the port and socket. Finally, the burrs are removed and polished on the inspection table to ensure the vertical and sealing effect of the port.
Benefits of technology
It improves the forming quality and efficiency of the plug-in flexible interface steel pipe, reduces the scrap rate, enhances the sealing effect and the service life of the steel pipe.

Abstract
The present invention discloses a stamping forming method for socket-type flexible joint steel pipes, belonging to the technical field of socket-type pipe forming. The stamping forming method for socket-type flexible joint steel pipes comprises the following steps: processing the end of the steel pipe; feeding the steel pipe into a stamping device, inserting a punch into the heated end of the steel pipe, and stamping and flaring one end of the steel pipe to form; feeding the steel pipe into a flat-mouth device to flat-mouth the flared end of the steel pipe; feeding the steel pipe after flat-mouth treatment into a forming device, forming the socket end through a socket forming mechanism arranged at one end of the forming device, and forming the spigot end through a spigot forming mechanism arranged at the other end of the forming device; feeding the formed steel pipe into an inspection table for inspection, removing burrs at both ends of the steel pipe and polishing to obtain a socket-type flexible joint steel pipe. By adopting the stamping forming method for socket-type flexible joint steel pipes of the present invention, the problems of low forming quality and high defective product rate of the existing socket-type flexible joint steel pipes can be solved.
