Embodiment Construction

[0028] 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.

[0029] 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 feeding and retracting mechanism used for a pipe facing machine. The cutter feeding and retracting mechanism comprises a gear disc, a servo drive motor, a cam disc and a bevel cutter mechanism, wherein the servo drive motor drives the gear disc to rotate, the cam disc is arranged to be matched with the gear disc, and the bevel cutter mechanism is arranged on one side, deviating from the gear disc, of the cam disc. The gear disc is provided with a plurality of first cam faces arranged facing toward the direction of the cam disc, and the first cam faces are evenly arranged in the peripheral direction of the gear disc. The cam disc is provided with a plurality of second cam faces which are matched with the first cam faces and evenly arranged in the periphery direction, when the servo drive motor rotates, the first cam faces move on the second cam faces and push the cam disc to perform axial movement along a pipe to be beveled.

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...
