Abstract
The invention belongs to the cutting technology field of a circular tube penetration hole of a steel building structure and particularly relates to a method for manually cutting an irregular plate tube penetration hole of an arc circular tube. The cutting method comprises the following steps of a, providing an arc circular penetration tube deepening drawing; b, lofting according to a deepened part drawing, locating the position of a circular tube to allow a penetration plane to be in a horizontal plane, marking out a three-point locating point according to requirements of the drawing, and popping up a penetration position line in a line popping way; repeatedly drawing the line for each penetration hole according to the way; c, according to the drawn position line, rechecking the penetration line, upon the correct size, and cutting the irregular penetration hole along the drawn position line.
Description
Technical field
The invention belongs to construction steel structure pipe intersecting mouth cutting technique field, be specifically related to a kind of arc pipe sketch plate pipe intersecting mouth hand cutting process.
Background technology
In the structural steelworks such as stadiums, conference and exhibition center, commercial center's roofing, there is a large amount of pipe related subgroup node, wherein the current intersection-line cutting machine that adopts of regular pipe intersecting mouth carries out intersecting mouth processing, but abnormity passes through mutually, and pipe is current to be processed without corresponding equipment, also temporary without corresponding processing technology, the Circular Tubular Joints of this type is made to be difficult to processing, can only by the change of design of node mode, or progressively cut the mode of progressively repairing by most fool to offer, efficiency is low, low precision.
In view of this, the invention provides a kind of arc pipe sketch plate pipe intersecting mouth hand cutting process, this case produces thus.
Summary of the invention
The object of the present invention is to provide a kind of arc pipe sketch plate pipe intersecting mouth hand cutting process, reduce the manufacture difficulty of this type of intersecting mouth, solve the difficult problem that this type of intersecting mouth is difficult to offer, accelerate making progress, improve production efficiency.
For achieving the above object, the technical scheme that the present invention specifically provides is: a kind of arc pipe sketch plate pipe intersecting mouth hand cutting process, comprises the steps:
A, provide arc and pass through pipe in-depth figure mutually;
B, foundation in-depth part drawing carry out setting-out, and pipe position, location makes to pass through plane place horizontal plane mutually, then according to drawing requirement, marks three-point fix point, then adopts the mode of snap the line to eject and pass through the position line mutually; Each intersecting mouth repeats line according to this mode;
C, according to the position line drawn, check intersection size errorless after, along draw the special-shaped intersecting mouth of position line hand cut.
Further, described step a: it is space curve that arc pipe and sketch plate intersecting mouth pass through outline line mutually, it is a plane and straight line that outline line is projected on sketch plate frontal, the sectional view that this intersection shows as plane and straight line must be provided in in-depth part drawing, and identify setting-out size, pass through pipe processing setting-out mutually for convenience of abnormity simultaneously, in part drawing, need this plane and straight line to rotate to be a horizontal linear.
Further, according to in-depth part drawing setting-out: first mark ground master drawing on horizontal moulding bed, next marks the positioning cross line of arc pipe inner arc, outer arc and both sides thereof, finds out termination construction layout point, arc pipe end 3 is overlapped, the locus of fixing arc pipe with ground layout point.
Further, mark three-point fix point: mark at least three anchor points successively at curved circular tube outer surface, and make a check mark, then according to three-point fix, adopt the mode of snap the line to eject required space intersection; When there is multiple intersection, each intersecting mouth repeats line according to this mode.
Further, along the intersection position line drawn, cutting intersecting mouth, after cutting, carries out retaining wall on slope and groove face is polished, namely completes the cutting of the intersecting mouth degree of precision that tube sheet passes through mutually.
Patent of the present invention has following characteristics and good effect:
One, arc pipe sketch plate pipe intersecting mouth hand cut technique, the arc pipe intersecting mouth passed through mutually for plate pipe provides a kind of new cutting technique, reduces the manufacture difficulty of this type intersecting mouth, solves the difficult problem that this type of intersecting mouth is difficult to offer.
Two, improve the competitiveness of the technology in this respect of enterprise, the processing and fabricating requirement of design engineer in this node can be met.
Three, the production efficiency improved, reduces cost of manufacture, shortens and makes the duration.
Next by reference to the accompanying drawings, the embodiment of the present invention is described in further details.
Accompanying drawing explanation
Fig. 1 is according to position line cutting intersecting mouth schematic diagram;
Fig. 2 is arc pipe sketch plate pipe tubular joint schematic diagram.
Detailed description of the invention
As shown in Figure 1-2, what the present invention disclosed is a kind of arc pipe sketch plate pipe intersecting mouth hand cutting process, and summation comprises the steps:
A, provide arc and pass through pipe in-depth figure mutually;
B, foundation in-depth part drawing carry out setting-out, and pipe position, location makes to pass through plane place horizontal plane mutually, then according to drawing requirement, marks three-point fix point, then adopts the mode of snap the line to eject and pass through the position line mutually; Each intersecting mouth repeats line according to this mode;
C, according to the position line drawn, check intersection size errorless after, along draw the special-shaped intersecting mouth of position line hand cut.
Above summation is specifically launched:
Further, described step a: it is space curve that arc pipe and sketch plate intersecting mouth pass through outline line mutually, it is a plane and straight line that outline line is projected on sketch plate frontal, the sectional view that this intersection shows as plane and straight line must be provided in in-depth part drawing, and identify setting-out size, pass through pipe processing setting-out mutually for convenience of abnormity simultaneously, in part drawing, need this plane and straight line to rotate to be a horizontal linear.
Further, according to in-depth part drawing setting-out: first mark ground master drawing on horizontal moulding bed, next marks the positioning cross line of arc pipe inner arc, outer arc and both sides thereof, finds out termination construction layout point, arc pipe end 3 is overlapped, the locus of fixing arc pipe with ground layout point.
Further, mark three-point fix point: mark at least three anchor points successively at curved circular tube outer surface, and make a check mark, then according to three-point fix, adopt the mode of snap the line to eject required space intersection; When there is multiple intersection, each intersecting mouth repeats line according to this mode.
Further, along the intersection position line drawn, cutting intersecting mouth, after cutting, carries out retaining wall on slope and groove face is polished, namely completes the cutting of the intersecting mouth degree of precision that tube sheet passes through mutually.
Above-described embodiment only illustrates inventive concept of the present invention for explaining, but not the restriction to rights protection of the present invention, all changes utilizing this design the present invention to be carried out to unsubstantiality, all should fall into protection scope of the present invention.
