Steel plate skiving, cutting bevel for welding device and method do not overturn
(1) technical field
The present invention relates to the forming technique of sheet material front skiving steel plate, cutting bevel for welding, particularly relate to the no track front skiving of ultra-thick plate, bent side plate and the device and method of groove cutting.
(2) background technology
For many years, in shipbuilding field and non-ship product manufacture process, the skiving to slab in the board material splice is taked the negative shape technology always.Use this forming method, on one side the operator will bend to look up the position line of skiving when cutting, Yi Bian control the cutting machine on the sheet material.Like this, when increasing labour intensity, also restricted cut quality.If adopt front skiving moulding, the plate end that keeps to the side more, the flame temperature at place, limit is low more, causes serious mass defects such as undercut, misrun, dross.In addition, handled the sheet material groove in the past and all adopt the cutting of semi auto cutting machine guide rail, this cut mode is inapplicable to handling the bigger bent side plate groove of curvature.If can only lean on the transfer of operator's craft during the bent side plate of cutting, so not only increase labour intensity, also reduced the quality of cutting.
(3) summary of the invention
The technical problem to be solved in the present invention provides shaped device and method that a kind of sheet material does not have track front skiving and bevel cut, and solving the sheet material skiving can only carry out causing the unwarranted technical barrier of precision with bevel cut manual setting track at reverse side.
The technical scheme that adopts is:

5, adjust vertical roll adjustment handwheel and cutting torch angle adjustment wheel simultaneously, thereby adjust to the angle of skiving or bevel cut.
6, carriage is installed to the end end of wanting cutting steel plate, notes cutting machine walking guiding directive wheel extension plate and the steel plate side coplane that will cut, and fixing locked pinching screw.
7, according to semiautomatic flame cutting machine cutting operation rules, send electricity, igniting, begin cutting.
It is new that cutting machine of the present invention walking guide, cutting torch rotation and fixed mechanism, carriage and semiautomatic flame cutting machine are formed a cover, and need not overturn can skiving sheet material and cut the cutting machine of bevel for welding.This kind cutting machine is applicable to the skiving steel plate fully, cuts the big bent side plate bevel for welding of each pattern curvature, has reduced labour intensity, has improved cut quality.
