Description
Technical field:
The utility model relates to a kind of steel pipe and makes treatment facility, is specifically related to a kind of processing apparatus for shaping of inside weld of ERW steel pipe.
Background technology:
The ERW steel pipe is the very general basic material of a kind of application, and a plurality of fields such as widespread and draining, chemical industry, mining, oil, electronics, shipbuilding, agricultural almost have the place of industrial plants that the application of steel pipe is just arranged.Most of in the market high-frequency welding steel pipe that adopts, this type of steel pipe low cost of manufacture, applied range, adaptability are strong, be subjected to users' welcome, but this type of steel pipe has a common defective, the weld seam of steel pipe inwall, solder joint are difficult for handling, the steel pipe that particularly internal diameter is less, length is long, the processing of inwall weld seam is a generally acknowledged difficult problem.At present the home and abroad also has some to handle removal methods, but these methods all need than complex apparatus, higher investment, and the processing time is long, processing cost is high, treatment effect is bad.
The utility model content:
The purpose of this utility model provides a kind of ERW steel pipe inwall weld seam and removes apparatus for shaping, it can be with cheap investment, simple equipment, handle weld seam, the solder joint of removing ERW steel pipe inwall fast, efficiently, easily, also have shaping operation, solved generally acknowledged difficult problem in the industry.In order to solve the existing problem of background technology, the utility model is by the following technical solutions: it comprises and drags axle 1, several annulus cuttves 2, polylith gasket ring 3, the periphery of annulus cutter 2 is made as blade, and several annulus cutter 2 cross-under separate with several piece gasket ring 3 between the annulus cutter 2 dragging on the axle 1.When the utility model is used, keep the diameter of annulus cutter 2 identical or bigger with the internal diameter of processed ERW steel pipe, the diameter of annulus cutter 2 is set according to demand, the utility model is inserted processed ERW steel pipe, drag axle 1 from the right side and haul out from the right side of ERW steel pipe until dragging axle 1, then the weld flush on the ERW steel pipe inwall, solder joint are then removed by annulus cutter 2.Of the present utility model dragging on the axle 1 can be provided with a plurality of annulus cuttves 2, gasket ring 3 between the annulus cutter 2 can increase or reduce, annulus cutter 2 at interval can be used in the periphery of gasket ring 3, also can be used for temporarily depositing smear metal and residue by dropping after 2 processing of annulus cutter, when when pull out on the right side of ERW steel pipe, smear metal and residue drop out automatically.
The diameter of several annulus cuttves 2 can increase from right to left successively gradually in the utility model.The annulus cutter 2 diameter minimums of the rightmost side, the relatively large solder joint, the weld flush that are used for bulk processing ERW steel pipe inwall, use the bigger annulus cutter of diameter 2 then and carry out precision processing, can guarantee that like this each annulus cutter 2 has different effects respectively, also can guarantee to replenish cutting after the blade of cutter weares and teares in front, can guarantee the quality removed like this, do not need frequent replacing stage property, alleviate the degree of treatment of rightmost side annulus cutter 2, allow each annulus cutter 2 all play effect, prolong the service life of annulus cutter 2.
The utlity model has simple in structure, investment is cheap, conveniently remove weld seam, the solder joint of ERW steel pipe inwall, it has fast, efficiently, advantage easily, solved generally acknowledged difficult problem in the industry.
Description of drawings:
Fig. 1 is a structural representation of the present utility model, and Fig. 2 is the B portion enlarged drawing of Fig. 1, Fig. 3 be the A-A of Fig. 1 to view, Fig. 4 is the structural representation of the specific embodiment two, Fig. 5 is that the B-B of Fig. 4 is to view.
The specific embodiment:
The specific embodiment one: referring to Fig. 1-3, this specific embodiment by drag axle 1, several annulus cuttves 2, polylith gasket ring 3, fixed stop 4, pad 5, holding screw 6 are formed, the periphery of annulus cutter 2 is made as blade, several annulus cutter 2 cross-under are dragging on the axle 1, separate with several piece gasket ring 3 between the annulus cutter 2, fixed stop 4 is fixed on the left end that drags axle 1, and pad 5 is arranged on the right side that drags right circles cutting ring 2 on the axle 1, and holding screw 6 is fastened on the right side of pad 5.Holding screw 6 is used for fastening annulus cutter 2 and gasket ring 3, keeps the stability of whole device.
When this specific embodiment is used, make that the diameter of annulus cutter 2 is identical with the internal diameter of processed ERW steel pipe, this specific embodiment is inserted processed ERW steel pipe, drag axle 1 from the right side and haul out from the right side of ERW steel pipe until dragging axle 1, then the weld flush on the ERW steel pipe inwall, solder joint are then removed by annulus cutter 2.Dragging on the axle 1 of this specific embodiment can be provided with a plurality of annulus cuttves 2, gasket ring 3 between the annulus cutter 2 can increase or reduce, can use annulus cutter 2 at interval, the periphery of gasket ring 3 also can be used for temporarily depositing smear metal and the residue by dropping after 2 processing of annulus cutter, when when pull out on the right side of ERW steel pipe, smear metal and residue drop out automatically.
The diameter of several annulus cuttves 2 increases from right to left successively gradually.The annulus cutter 2 diameter minimums of the rightmost side, the relatively large solder joint, the weld flush that are used for bulk processing ERW steel pipe inwall, use the bigger annulus cutter of diameter 2 then and carry out precision processing, can guarantee that like this each annulus cutter 2 has different effects respectively, alleviate the degree of treatment of rightmost side annulus cutter 2, allow each annulus cutter 2 all play effect, prolong the service life of annulus cutter 2.
Described annulus cutter 2 is provided with circular arc 3-1 with the junction of gasket ring 3.The circular arc 3-1 that the junction of annulus cutter 2 and gasket ring 3 is provided with can have the chip breaking effect to the smear metal that annulus cutter 2 cuts, and prevents that smear metal is in inside winding, curling; Circular arc 3-1 can also reduce the stress of annulus cutter 2 and concentrate, and the stress that allows annulus cutter 2 produce disperses, and has reduced disconnected broken, the cracking of annulus cutter 2, has prolonged the service life of annulus cutter 2.
The specific embodiment two: referring to Fig. 4, this specific embodiment is that with the difference of the specific embodiment one its increase has dressing stick 7, dressing stick pad 8, dressing stick holding screw 9, dressing stick 7 is an annular, the diameter on dressing stick 7 right sides is slightly less than the diameter in left side, the annulus limit, left side of dressing stick 7 is provided with weld flush groove 7-1, dressing stick 7 is arranged on the right side of holding screw 6, and dressing stick pad 8 and dressing stick holding screw 9 are successively set on the right of dressing stick 7.Dressing stick pad 8 and dressing stick holding screw 9 are used for fixing dressing stick 7, have guaranteed the stable of dressing stick 7.
Exist the effect of bump, gravity to make small part ERW steel pipe produce sex change because the ERW steel pipe is unavoidable in production, handling process, make the inwall circular arc produce distortion, dressing stick 7 is arranged on the place ahead of annulus cutter 2, can be so that annulus cutter 2 can have the effect of shaping to a small amount of crushed element of ERW steel pipe before processing welding lines projection, solder joint, corrected the inwall of ERW steel pipe, also can prolong the service life of annulus cutter 2 so that annulus cutter 2 operate as normal; Because the rightmost side gets the diameter minimum of annulus cutter 2, rightmost side annulus cutter 2 rocks in the ERW steel pipe easily, and dressing stick 7 can also have the effect of guiding.Other composition is identical with the specific embodiment one with annexation.
