Double-end saddle type welding groove machining production line

Abstract

The invention discloses a double-end saddle type welding groove machining production line which comprises a material channel, a fixed saddle beveling machine and a movable saddle beveling machine. Thefixed saddle beveling machine and the movable saddle beveling machine are arranged at the two ends of the material channel correspondingly, and the height of the central axis of the fixed saddle beveling machine and the height of the central axis of the movable saddle beveling machine are equal to the height of the central line of the material channel. The fixed saddle beveling machine is fixed to the ground, the movable saddle beveling machine is fixed to a movable base, the movable base is fixed to a guide rail, the movable base is synchronously connected to a servo motor through a lead screw assembly, and the servo motor drives the lead screw assembly to move, so that the movable base does front-and-back reciprocating motion on the guide rail. The production line is simple in structural design, capable of automatically machining double-end saddle grooves, good in machining quality, high in efficiency, adjustable in parameter, wide in machining range and high in mechanization degree.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing, and in particular relates to a double-headed saddle-type welding groove processing production line. Background technique [0002] In the design of boiler piping, in order to ensure the full penetration of the welding between the pipe and the header, the welding groove of the pressure vessel pipe and the header is usually designed as a saddle shape. The saddle bevel profile is the continuous intersecting line formed by the pipe and the header surface, which cannot be processed by ordinary beveling machines. Many pressure vessel manufacturers basically use single-end manual processing in the saddle beveling process, which is inefficient. The molding quality varies, and the manufacturing cost increases. When there are saddle-shaped welding grooves at both ends of the pipe, manual positioning of a single device, because the saddle groove end is not flat, cannot be accurately positioned...

Problems solved by technology

The saddle bevel profile is the continuous intersecting line formed by the pipe and the header surface, which cannot be processed by ordinary beveling machines. Many pressure vessel manufacturers basically use single-end manual processing in the saddle beveling process, which is inefficient. The molding quality varies, and the manufacturing cost increases

When there are saddle-shaped welding grooves at both ends of the pipe, manual positioning of a single device, because the saddle groove end is not flat, cannot be accurately positioned to determine the processing length. In addition, when the saddle grooves at both ends require the same circumferential phase, it must Use dedicated processing lines to solve these problems
