Portable type pipe electric bevelling machine

Abstract

The invention discloses a portable pipe grooving machine which is mainly composed of a fixing device, a power cutting device and a feeding device, etc. The fixing device includes a mounting rack, a cone-cylinder, a tensioning block, a pulling rod, a ratchet spanner and so on; the power cutting device includes a cutter head, an electric part, a supporting upper pole support, an adjusting rod, a sill bar, a moving sleeve and so on; the feeding device includes an axial feed plate and a radial feed device; thereby the tensioning block of the fixing device can be adjusted easily and rapidly, the fixing device is enabled to be fixed in the pipe rapidly, and the time is saved; when machining pipe grooves, a bracket is not needed to support the pipe, a hoist or a manpower is not needed to lift and handle the pipe, the pipe only need to be moved on the spot by an angle within 180 DEG, so that the mechanical power and the manpower are saved; the manner of directly rotary-cutting a pipe end by the cutter head of the prior device is changed into the manner of partial-cutting a pipe wall and then grooving the pipe by the cutter head along with the rotation of the whole power cutting device, thereby the specification of the pipe is increased without changing the cutting power thereof, the machine is portable, and the cost is low.

Description

technical field [0001] The invention relates to a portable pipe beveling machine, which is used for beveling the pipes to be welded so as to meet the standard requirements. Background technique [0002] At present, pipe beveling is done by mechanical cutting or gas cutting and grinding. Using mechanical beveling is easier to ensure the quality. Because of its large equipment, heavy weight and high cost, it cannot completely replace manual beveling. Grinding the bevel after gas cutting is simple. Flexibility is still widely used. The cutting device of the existing beveling machine has to increase the power part and the mechanical part with the increase of the pipe specification, so as to meet the needs of cutting pipe beveling. When cutting the pipe, the pipe needs to be placed on the bracket On the other hand, larger pipes need to be lifted by a crane or moved by multiple people, which is time-consuming and labor-intensive. Contents of the invention [0003] The purpose o...
