Abstract
The utility model discloses a hydraulic online inner-welding-seam removing device for welded pipes. The hydraulic online inner-welding-seam removing device comprises a mounting plate, a pull lever fixedly connected with the mounting plate, an impedor connected with the pull lever, a connecting bar connected with the impedor, and a cutter bar fixedly connected with the connecting bar. Two guide pulleys are arranged on the upper end of the cutter bar, a lower roller is fixedly connected onto the lower end of the cutter bar through a lower-roller holder, a cutter seat used for fixedly mounting an annular blade for removing an inner welding seam is arranged at the tail end of the cutter bar, and the annular blade is fixed on the cutter seat through a fixing screw. The cutter bar is further internally provided with a hydraulic cavity which is connected with a hydraulic-oil input pipe. The impedor is connected with a cooling-fluid input pipe. Specifications and inner diameter ranges of the welded pipe with the inner welding seam removed range from phi32mm to phi143mm, so that the hydraulic online inner-welding-seam removing device has the advantages that the removed inner welding seam is fine and stable in quality, and meanwhile, production cost is low and the like.
Description
Technical field
The utility model belongs to welded tube and removes inside weld device, is specifically related to a kind of device of online removal welded tube inside weld of fluid pressure type.
Background technology
Along with industrial expansion, the industries such as automobile, boiler, oil need more accurate welded tube, require welded tube inside weld to remove, but how to remove welded tube inside weld and become a technical barrier, to effectively remove welded tube inside weld and just need corresponding device, as the firm knife bar blade consistent with welded tube circularity with fillet circularity,, therefore there is corresponding welded tube inside weld removal device in the problem that its bead of inside weld that also needs solution to scrape comes off.The mode that welded tube goes inside weld device to remove inside weld according to it is divided into outer two kinds of online and line, by its control mode, is divided into mechanical type and fluid pressure type, at present comparatively conventional be fluid pressure type remove online inside weld device.Germany Sa A company is that main in the world welded tube goes inside weld device manufacturer, and it goes inside weld device technique comparatively advanced, but introduce a set of the said firm, goes inside weld device to need cost up to a million, and cost is higher.How to produce that a set of to guarantee to go the superior in quality stable and relatively low inside weld device that goes of cost of inside weld be the technical barrier that domestic steel pipe manufacturing industry is faced always.
Summary of the invention
For the deficiencies in the prior art, the utility model aims to provide a kind of superior in quality stable and low fluid pressure type welded tube of production cost of inside weld that goes and removes online inside weld device.
For achieving the above object, the utility model adopts following technical scheme:
Welded tube removes an inside weld device online, comprises installing plate, the drawbar being fixedly connected with installing plate, the impedor being connected with drawbar, the connecting rod being connected with impedor and the knife bar being fixedly connected with connecting rod; Its upper end of described knife bar is provided with two directive wheels, its lower end is fixedly connected with a lower roll wheel by lower roll wheel seat, described knife bar tail end is provided with for fixedly mounting the tool rest of the annular blade of inside weld, and this annular blade is fixed on above-mentioned tool rest by blade fixed screw; In described knife bar, be also provided with a hydraulic cavities, described hydraulic cavities connecting fluid force feed input pipe; Described impedor connects coolant inlet pipe.
Further, on described tool rest, be also provided with scrape depth set screw and lock screw.
The utlity model has following beneficial effect:
A kind of fluid pressure type welded tube of the utility model removes inside weld device online, and its welded tube internal diameter specification limit of removing inside weld is Φ 32mm to Φ 143mm, and inside weld is superior in quality has the advantages such as production cost is low in stable guaranteeing to go.
Accompanying drawing explanation
Fig. 1 is the structural representation that a kind of fluid pressure type welded tube of the utility model removes inside weld device online.
The specific embodiment
Below in conjunction with drawings and the specific embodiments, the utility model will be further described, understands the claimed technological thought of the utility model so that clearer.
Be illustrated in figure 1 the present embodiment fluid pressure type welded tube and remove online inside weld device, comprise installing plate 1, the drawbar 4 being fixedly connected with installing plate 1, the impedor 5 being connected with drawbar 4, the connecting rod 6 being connected with impedor 5 and the knife bar 7 being fixedly connected with connecting rod 6, described knife bar 7 upper ends are provided with two directive wheels 8, its lower end is fixedly connected with a lower roll wheel 15 by lower roll wheel seat 14, these knife bar 7 tail ends are also provided with one for fixedly mounting the tool rest 16 of the annular blade 13 of welded tube inside weld, this annular blade 13 is fixed on above-mentioned tool rest 16 by blade fixed screw 12, in knife bar 7, be also provided with a hydraulic cavities 9, described hydraulic cavities 9 one end connecting fluid force feed input pipes 2, described impedor 5 one end connect coolant inlet pipe 3.For ease of adjusting annular blade 13 angles, on described tool rest 16, be also provided with scrape depth set screw 10 and lock screw 11.
For a person skilled in the art, can make other various corresponding changes and distortion according to technical scheme described above and design, and these all changes and distortion all should belong to the protection domain of the utility model claim within.
