Milling tool for forming super-thick steel plate groove

Abstract

The invention discloses a milling tool for forming super-thick steel plate groove, comprising a cutter body (1), a cutter holder (2), cutter blades and a dull-edged cutter piece (4); the cutter holder (2) is fixedly arranged on the step surface (10) of the cutter body (1); an upper groove cutter blade and a lower groove cutter blade (3) are fixed in an upper cutter blade groove and a lower cutter blade groove (14) in the cutter holder (2); the dull-edged cutter piece (4) is fixed in a dull-edged cutter piece positioning groove (16) of the cutter holder (2); and a dull-edged cutter blade (25) is fixed in a dull-edged cutter blade groove (15) of the dull-edged cutter piece (4). The milling tool for forming super-thick steel plate groove provided by the invention has the beneficial effects that all the cutter blades installed on the cutter holder are in overlap joint, thus a complete groove profile cutting blade is formed, and a required V-shaped or U-shaped butt-welding welding surface can be machined one time; through the installation of adjusting gaskets with different thicknesses on the bottom of the dull-edged cutter piece, the adjusting function of the dull-edged cutter piece is realized, thus the groove dimensions with different dull-edged widths can be met; and through replacing different cutter holders, the machining of profiles of different angles can be realized.

Description

technical field [0001] The invention relates to the field of metal cutting, in particular to an extra-thick steel plate groove forming milling cutter. Background technique [0002] For the processing of the welding groove surface of extra-thick steel plate, especially the processing of the welding groove surface of 60mm~115mm steel plate, there is no forming milling tool that can process the complete groove surface at one time in China. At present, in the field of welding, especially in the field of welding of extra-thick steel plates, flame cutting, carbon arc gouging and other processing methods are often used in domestic processing of groove profiles. The disadvantage of this method is that not only the angle error of the processed groove profile Large, and the surface roughness of the groove after cutting is also poor, which will directly affect the welding quality, so the subsequent sequence needs to be polished and smoothed to remove the scale, and then welded, so the ...

Problems solved by technology

At present, in the field of welding, especially in the field of welding of extra-thick steel plates, flame cutting, carbon arc gouging and other processing methods are often used in domestic processing of groove profiles. The disadvantage of this method is that not only the angle error of the processed groove profile Large, and the surface roughness of the groove after cutting is also poor, which will directly affect the welding quality, so the subsequent sequence needs to be polished and smoothed to remove the scale, and then welded, so the processing is complicated and cumbersome, and the processing efficiency is not high. It is only suitable for small Mass production, and in mass production, the current processing methods such as flame cutting and carbon arc gouging obviously cannot effectively meet the requirements of production.
