Description
The present invention and iso-curvature band awl lumen tubing inner chamber processing, particularly the inner chamber process equipment of metallurgical industry casting mold for continuous casting pipe.
The roughing of linear pattern lumen tubing, at present, majority is hot rolling, cold rolling and drawing and forming, minority is that essence is cast type, to short linear pattern lumen tubing fine finishining, turning moulding, broaching moulding or punch forming is arranged at present.The turning moulding is applicable to the circular section, and broaching or punch forming are applicable to arbitrary section.Because at present the structure of broaching tool is restricted, the length of being broached is limited, and the inner chamber of band awl can not be broached at all, and the guiding of broaching tool is that the inner chamber of tube part is finished.
The purpose of this invention is to provide a kind of novel broaching equipment, it is the longer iso-curvature band awl of fine finishining lumen tubing inner chamber effectively.
The object of the present invention is achieved like this, make an iso-curvature band and bore and have the profiling guide rail of sliding keyway, slip broach shell and arc feather key are housed on the profiling guide rail, then the profiling guide rail is penetrated in the iso-curvature pipe fitting base that makes, accurately adjust its relative position, again profiling guide rail, pipe fitting blank are fastened on the frame, draw the slip broach shell by the power combination that motor, decelerator, reel, assembly pulley, rubbing property steel cable are formed.Like this, on the slip broach shell, load onto difform sliding blade, just can process the tube intracavity of different cross section iso-curvature band awl.
The iso-curvature band is bored and the profiling guide rail of sliding keyway is arranged is produced like this: at first produce the guide rail that sliding keyway was bored and had to a linear pattern band with universal machine tools.Its cross section outer contour shape is similar to the tube intracavity cross sectional shape, cross-sectional sizes should be reserved broach shell space and volume bits space, its tapering is identical with the tube intracavity tapering, its length is greater than the length of pipe fitting itself, its two sliding keyway is processed respectively and is being wanted on crooked two planes, and two key slot side are parallel to each other, two keyway bottom surfaces with want the flexural center plane parallel, two keyways are symmetrical about the central plane of wanting bending, and its surface roughness is 1.6.The band awl guide rail that manufacturing is good rolls out desired iso-curvature on the furling plate round machine of autocracy (be that guideway centreline's planar curvature equates everywhere, guide rail equates with pipe fitting central plane amount of curvature), also can on common furling plate round machine, roll out desired iso-curvature, but the surface roughness of winding up roller and hardness to be higher than the surface roughness and the hardness of guide rail.Also can make the central plane curvature of profiling guide rail reach the iso-curvature requirement with making good linear pattern band awl guide rail hot-roll forming and cold by force in the mould of autocracy.The mold cavity surface of mould slightly degree of making is more than 1.6.
The intracavity section of slip broach shell is similar to the guide rail cross section, cavity shape is a linear pattern, exterior cross-section is similar to the inner cavity of component cross section, slip broach shell end anise has the screw of using for pull-broaching, the long sliding eye that the dress blade is arranged all around, the bolt hole that the sliding eye two ends have pressing spring plate precompressed blade to use, sliding eye can be made one or more groups.Generally making two groups is advisable.Every group of 8 sliding eyes.Slip broach shell inner chamber is a linear pattern, and cross-sectional sizes is slightly larger than the guide rail maximum cross-section, and it can be slided freely on guide rail, and the broach shell inner chamber has two bottoms, sidepiece two keyways parallel to each other, and its position is corresponding with the keyway position on the guide rail.There is the bolt hole of adjusting the arc feather key keyway inside.
The width of arc feather key is determined by the sliding keyway on the iso-curvature band awl profiling guide rail, length is determined by the length of slip broach shell, surface roughness is more than 1.6, the cambered surface of arc feather key is to come out with the preparation of keyway bottom surface, the facing-up of iso-curvature band awl guide rail, and the pin-and-hole of locating on the slip broach shell is arranged on the arc feather key.
Sliding blade is the sliding blades of many groups, and material can be with high-speed steel or carbide alloy manufacturing, 8 every group, be split to form by the tube intracavity cross sectional shape, and promptly every group of blade unit outline that gets up is identical with the tube intracavity cross sectional shape.Interior profile is identical with the guide rail cross section, and the difference in size between every group of blade is formulated according to cutting data, and the pre-compressed spring board slot is arranged on the blade.General one group of blade front is arranged four, and the back is arranged four, and four blade widths of back should guarantee to machine away preceding four green surfaces that blade stays.
The frame manufactured materials select that cast steel, cast iron, steel construction, reinforcing bar coagulate soil for use.
The motion of slip broach shell is by suitable motor, decelerator, reel, assembly pulley, rubbing property wire rope traction.
Iso-curvature pipe fitting blank processes like this: the autocratic furling plate round machine with adjusting width, straight tube spare blank is rolled out needed curvature, and cut off according to required length then.Also can in the mould of autocracy, be pressed into required curvature to straight tube spare blank, cut off according to required length then.Also can essence cast type.
Assembly pulley is made up of two pulleys, and four rubbing property steel cables that traction slip broach shell is used are on two pulleys, in order to be adjusted at four rubbing property steel cable unbalance stress that cause owing to break-in in the broaching process automatically.
The present invention bores and has the manufacturing issue of sliding keyway profiling guide rail because solved the iso-curvature band, thereby changed traditional broaching tool structure and guidance method.Make the inner chamber handling ease of iso-curvature band awl lumen tubing realize.
The concrete structure of invention can well be understanded from the description of following most preferred embodiment to accompanying drawing.But this does not also mean that accompanying drawing and explanation defines scope of the present invention.
Motor 7, elasticity catcher 8, decelerator 30, reel 31, elasticity catcher 32, roller stand 33 are housed on the frame 27, adjust plate 29,21,2.Iso-curvature band awl profiling rail brackets 1,5 is welded on the tuned plate 29,21, adjust bolt 20,19,10,11 and can adjust the height of profiling guide rail 18, adjust the height of bolt 16,15 adjustable homogeneous tube spares, adjusting bolt 25 can make clamping seats 23,17 move forward and backward, adjust the front and back position of pipe fitting 14, after treating that the pipe fitting 14 and the mutual alignment of guide rail 18 are adjusted, fastening bolt 25,24,22,28.Rubbing property steel cable 12 1 ends are connected with special shaped screw bolt 26 on the slip broach shell 13, and the other end is connected with assembly pulley 9.Two arc feather keys 34,35 are housed on the slip broach shell 13, the keyway fit clearance of arc feather key 34,35 and iso-curvature profiling guide rail 18 can be by the bolt adjustment on the slip broach shell, sliding blade 42,43,37,36 is contained in the long sliding eye of slip broach shell 13, and compress in advance by spring 38,41 bolts 40,39, guarantee that blade in slip cutting (or extruding) process, keeps boring contacting of profiling guide rail 18 outer surfaces with the iso-curvature band eventually.On the assembly pulley 9 steering wheel is housed, can rolls on frame 27, an end connects rubbing property steel cable 12, and the other end connects reel 31 by steel cable 6, is out of shape in the broaching process for preventing thin-wall pipe, above clamping seats 23,17, cover at pressing plate 3, and fastening by bolt 4.The design of reel should make rubbing property steel cable 12 not rub with tube intracavity.
