Description
Technical field
The utility model relates to a kind of equipment of pipe fitting end processing, and especially a kind of saddle-shape pipe end cutter sweep belongs to the technical field that pipe end cuts.
Background technology
Pipeline transports passage as common medium, in feedwater, draining, heat supply, give gas, long apart from being widely used in transfer oil and natural gas, agricultural irrigation, hydraulic engineering and the various commercial plant, steel pipe is particularly common.The connection of pipeline mainly contains that thread connection, flange connect, socket joint connects and several different methods such as welding, and wherein the intensity and the sealing that connect of welding is best, is applicable to various pipelines, labor and material saving, but must cut off pipe and pipe connector during dismounting.Can not the intersection branched structure need be used in the pipeline with avoiding, the cutting processing of intersection need be carried out the arm pipe end at the position that intersects, to satisfy the performance requirement that its erection welding is communicated with, because of its pipe end shape exactly likes saddle, the unified saddle-shape pipe end that abbreviates as.
Cutting processing for steel pipe saddle-shape pipe end, usually adopt manual mode to mark the position of saddle-shape intersection and carry out mark at pipe end, use cutting torch to carry out the manual operations cutting then, cutting technical ability to operating personnel is had relatively high expectations, it is bigger influenced by subjective human factor, the pipe end quality that processes is difficult to guarantee that dimensional discrepancy is bigger; And for the saddle-shape pipe end that groove is arranged, cut quality more be cannot say for sure to demonstrate,prove, and has had a strong impact on the workmanship of this structure.
After also having pipe end to adopt cutting stock, carry out Milling Process after adopting the certain angle of milling head deflection, the caliber of processing pipe end must not be greater than the diameter of milling cutterhead, and tube length is long and have the saddle-shape pipe end of groove to process.Also have the profiling mould of employing to carry out turning processing, pipe end fineness is better, is applicable to the pipe fitting that caliber is little, length is less.Caliber is big more, and length is long more, requires also high more to employed lathe.
More existing equipment producers develop the pipe end cutting equipment, excision forming is pretty good, the workpiece that adopt are fixed more, and equipment rides on the tubular workpiece, and pattern and equipment are fixed, keep concentric with workpiece, cutting torch rotates around axis of workpiece, acts on pattern by pinch roller, in rotation, the movement locus of cutting torch is consistent with the pattern end surface shape, and cutting torch rotates a circle and finishes the cutting processing of pipe end.Use this kind equipment to be fixed in the certain height position to tubular workpiece, and make cantilever configuration; Need on the equipment to arrange that transmission mechanism is to satisfy cutting torch rotatablely moving around axis of workpiece; Balance and stability when driving mechanism and cutting torch support need guarantee that it rotates, structural configuration is had relatively high expectations; When carrying out the conversion of bevel cut angular adjustment, cutting torch stretches out long forward, be difficult to guarantee the stationarity when it rotates a circle motion; Cutting torch cuts when at the uniform velocity rotating, rotate to the different position of workpiece circumference, the slag flowing velocity that cuts out has nothing in common with each other, the direction of workpiece both sides slag is also inconsistent, thereby needed cutting speed and cutting torch inclination angle also have nothing in common with each other, existing equipment can't satisfy required speed and angle adjustment, or adjusts and realize very difficulty, also influences the stationarity and the security of equipment operation when carrying out angle adjustment easily; For the bigger workpiece of different caliber great disparities, need to adopt different positioning housings and drive rotating mechanism, make the cutting equipment weight of big caliber increase severely, perhaps need to adopt the high-strength alloy material to alleviate gross weight of equipment, cost is higher, place difficulty during the pipe end cutting, the move operation after the cutting is also comparatively difficult; Need the concordant pipe end of cutting, need to change pattern, need shutdown operation.
Also have equipment that equipment producer develops to use the numerical control programming mode pipe end is carried out cutting processing, the manufacturing cost of equipment is higher, and these all are unfavorable for obtaining in a large number, penetration and promotion fast and use.
