5, the high facet of the good efficiency of quality is first obtained it is necessary to select suitable cutting parameter.
6, big to internal cavity, longilineal workpiece, the with due regard to situation such as deformation retract, at hole column pitch,
The aspects such as allowance carry out artificial compensation.
Two, semi-automatic gas cutting machine processing aspect
The workpiece that 1, numerical control gas cutting machine is cut off material uses semi-automatic gas undercutting row groove chamfering, utilizes guide rail to enter
Row is mobile, solves linear groove chamfering.
2, guide rail guarantees before laying that the steel plate surface of contact is clean and tidy without protrusion and other impurity, semi-automatic gas cutting machine
First-elected mobile smooth, affect groove slot surface quality in order to avoid colliding with.
3, the workpiece less to breadth, need to be put in big steel plate limit, puts guide rail by the big plane of steel plate,
Realize semi-automatic gas cutting groove chamfering.
4, first calculate at the plane of groove chamfering by groove size and size at side before cutting, at slot two ends
It is both needed to mark, then connects and mark groove contour line, verify to guarantee accurately, and can be as gas cutting alignment line.
5, for the ease of alignment flame, as far as possible from the beginning of perpendicular one end.
Production and processing with regard to the product such as metal press and table top below describes present invention process processing method in detail.
Seeing plate parts 100 thickness that Fig. 1 and Fig. 2, Fig. 1 and Fig. 2 provide is 40mm, and material is Q235,
The edge of this plate parts is formed the Inner arc of internal cavity by the straight edge 101, a section that one section of precision is Ra6.3
Edge 102 and one section of precision are the straight edge that the straight edge 103, a section of Ra6.3 has straight line shaped chamfer groove
104, one section of straight edge 105, a section with straight line shaped chamfer groove has the straight flange of straight line shaped chamfer groove
106, one section of edge has the arc edge 107, a section of circular arc groove and has the straight edge of straight line shaped chamfer groove
108, one section of straight edge, 110, one section of beveled edge 111 of 109, one section of straight edge and one section of straight edge 112, its
One end of middle straight edge 101 is connected with the one end at Inner arc edge 102, the other end at Inner arc edge 102
Being connected with straight edge 103 one end, the other end of straight edge 103 is vertical with one end of straight edge 104 to be connected,
