Embodiment Construction

[0029] The present invention will be described in detail below in conjunction with various embodiments shown in the drawings. However, these embodiments do not limit the present invention, and any structural, method, or functional changes made by those skilled in the art according to these embodiments are included in the protection scope of the present invention.

[0030] Please refer to Figure 1 to Figure 12 Shown is a preferred embodiment of the knife advancing and retreating mechanism 22 of the present invention. The advancing and retreating knife mechanism 22 of the present invention is mainly applicable to the moving head frame 2 of a pipe beveling machine (not shown), so as to perform beveling operation on the pipe (not shown). In this embodiment, the advancing and retreating knife mechanism 22 can also perform a cutting operation on the pipe. The moving head frame 2 includes a fixed box body 21 , the advancing and retreating knife mechanism 22 fixed in the fixed box ...

Abstract

The invention provides a cutter advancing and retreating mechanism for a pipe beveling machine. The cutter advancing and retreating mechanism comprises a transmission mechanism, a push disc connected with the transmission mechanism, a cutter head component arranged on one side of the push disc and a plurality of steering mechanisms connected between the push disc and the cutter head component, wherein the cutter head component comprises a cutter head provided with an accommodating chamber for accommodating pipes to be beveled and a plurality of cutter boxes movably fixed on the cutter head, and beveling cutters are fixed on the cutter boxes; the steering mechanisms are triaxial link mechanisms and comprise first rotating shafts fixed on the cutter head, second rotating shafts fixed on the cutter boxes, third rotating shafts connected with the push disc, and connecting rods respectively used for connecting the first rotating shafts and the third rotating shafts, as well as the second rotating shafts and the third rotating shafts.

Description

technical field [0001] The invention relates to the technical field of pipe processing, in particular to a knife advance and retreat mechanism for a pipe beveling machine. Background technique [0002] In the process of pipe processing, in order to adapt to the grooves required for welding pipes of different materials such as carbon steel, stainless steel, alloy steel, and cast iron, lathe turning or oxygen cutting and hand wheel grinding are generally used for processing. However, the lathe turning processing equipment is bulky and heavy, and is only suitable for processing in a fixed location. For large-diameter steel pipes, transportation and clamping are very inconvenient. Although oxygen cutting and manual grinding wheel grinding can be processed on site, the surface quality of the processing is poor and the efficiency is low, and the metal lattice of the processed workpiece is easy to change after being heated, and the internal quality of the corresponding material cha...
