Large-scale pressure vessel tapping and beveling all-in-one machine

Abstract

The invention discloses a large-scale pressure vessel tapping and beveling all-in-one machine. The all-in-one machine comprises a rectangular frame, a cylindrical wall, a plasma cutting head, a fixingblock, a rocker, a positioning groove, a positioning rod, a motor and a support. The all-in-one machine has the beneficial effects that the motor drives the rocker to rotate, the rectangular frame isalways attached to the cylinder wall in the rotating process, the plasma cutting head always faces a rotating shaft, the angle is adjustable, grooves of various angles can be machined, the position of the positioning rod can be adjusted on the rocker, holes of different diameters can be cut, operation is easy, convenient and fast, the groove machining quality is high, the characteristics of beingsmall, portable and easy to operate are achieved, single-piece small-batch machining production can be carried out, and a round hole with a standard groove can be simply and rapidly cut.

Description

technical field [0001] The invention relates to a cutting and opening device, in particular to an integrated machine for opening and beveling a large pressure vessel, and belongs to the technical field of plasma cutting at intersecting lines of pressure vessels. Background technique [0002] Cutting round holes on the pressure vessel wall mainly adopts manual plasma cutting and intersecting line plasma cutting, among which manual cutting is more common. Manual cutting needs to first hoist the connecting pipe to be welded on the pressure vessel wall to draw the line, and then hold it The plasma cutting head cuts along the line, the incision is uneven, and the angle of the bevel cannot be guaranteed. The cutting edge needs to be polished later, which is time-consuming and laborious, and the economy is relatively low. Due to the uneven cutting edge, the gap at the root of the groove is different during welding, and the place with a large root gap needs to be filled with more we...

[0002] Cutting round holes on the pressure vessel wall mainly adopts manual plasma cutting and intersecting line plasma cutting, among which manual cutting is more common. Manual cutting needs to first hoist the connecting pipe to be welded on the pressure vessel wall to draw the line, and then hold it The plasma cutting head cuts along the line, the incision is uneven, and the angle of the bevel cannot be guaranteed. The cutting edge needs to be polished later, which is time-consuming and laborious, and the economy is relatively low

Due to the uneven cutting edge, the gap at the root of the groove is different during welding, and the place with a large root gap needs to be filled with more welding materials. Due to the difference in the content of welding materials at the weld, the welding quality is affected, and the intersecting line The cutting machine is expensive and occupies a large area. It can only cut cylinders with relatively small diameters. During processing, the cylinder needs to be clamped on one side of the chuck, which is inconvenient to operate and requires high-level programming operators. Based on this , this application proposes an integrated machine for opening and beveling large pressure vessels
