Elbow pipe double-end welding groove machining tool

Abstract

The invention discloses an elbow pipe double-end welding groove machining tool and mainly relates to the field of mechanical manufacturing. The elbow pipe double-end welding groove machining tool comprises a workbench, three elbow pipe supports, a pressing device and a beveling machine. The three elbow pipe supports are arranged on the workbench. Each elbow pipe support is provided with a plurality of cambered surface seat openings. The pressing device comprises a portal frame capable of being rotated to open and close, hydraulic cylinders and cambered pressing plates. A fixed rotary column isrotatably connected to the workbench. The hydraulic cylinders are arranged on a cross beam. The beveling machine is arranged on the outer side of the left port support and the outer side of the rightport support. Moreover, the beveling machine is matched with the end faces of the two sides of an elbow pipe when conducting beveling. The elbow pipe double-end welding groove machining tool has thebeneficial effects that the machining tool can be suitable for double-end groove machining of a large elbow pipe of a hoisting upper part of a gantry crane and can conduct machining on double-end grooves of various types of elbow pipe workpieces in one working position, and the occupied workshop area of the working position is greatly reduced.

Description

Technical field [0001] The invention relates to the field of mechanical manufacturing, in particular to a tooling for processing a bevel double-head welding groove. Background technique [0002] Groove is a groove processed into a certain geometric shape of the part to be welded of the weldment. The groove is mainly used to weld the workpiece to ensure the welding degree. [0003] Through a full search, a tool for double-headed elbow processing is introduced in the Chinese invention patent with the application number 201620166618X, the filing date of 2016.03.06, and the name of the invention for a elbow double-end fracture processing mold. . After communicating with the inventor, the inventor emphasized that this kind of tooling for double-ended rupture processing of elbows should be suitable for processing small elbow double-ended fractures. Because for the processing of large-scale elbow double-ended breaks, the elbow is generally hoisted to the work station by aerial crane, a...

AI Technical Summary

Problems solved by technology

In this published patent, the so-called upper mold plate is always set above the lower mold plate, and the horizontal dislocation cannot be formed between the upper and lower mold plates so that the upper plate can be moved horizontally above the lower plate. cannot be placed on the lower template

Most of the above-mentioned patents have relatively large limitations in use

[0004] Another point is that the pipe bend double-end break processing mold in the above-mentioned patent can only be applied to one type of bend pipe double-end break processing, because different types of pipe bend workpieces have different pipe diameters, but different models The angle of the bending workpiece is certain, that is to say, the central angle of the circle where the bending workpiece is located is certain

If the above-mentioned patented technology is used, an independent station is required for the bevel processing of each type of bent pipe workpiece, which will occupy a large workshop area and waste a lot of space. This technology has great practical shortcomings.
