Abstract
The utility model discloses a longitudinally welded pipe inner burr removal cutter, which comprises a body and a blade. A guide wheel is arranged on the top portion of the body, the bottom portion of the body is provided with a support rod wheel, and the left side and the right side of the cutter are respectively provided with a side guide wheel. Each side guide wheel is mounted on an elastic seat comprising a support block, the support block is connected with the body via a bolt, and a compression spring is disposed between the support block and the body. By adding the side guide wheels on the left side and the right side, the cutter has limit and guiding function with an inner wall of a steel pipe in directions of upside, downside, left and right, thereby ensuring fine contact of the blade and welded joint portions and improving inner burr removal effect.
Description
Technical field
The utility model relates to a kind of cutter arrangement, is specifically related to a kind of cutter that is used to remove burr in the ERW.
Background technology
The commissure of welded still pipe can produce the welding burr, and wherein the burr on the outer wall can be removed with a lot of conventional meanses.For some high-quality ERW, the interior burr on its inwall also needs to remove, and burr needs special-purpose cutter to carry out in removing.
China's utility model patent 200620023693.7 discloses a kind of ERW lining inner burr removing apparatus of mechanical type advance and retreat cutter, and two guide wheels have been installed on the knife bar end face of this device, can contact with the upper wall of steel pipe; Be provided with a support wheel on the bottom surface of knife bar, can contact with the lower wall of steel pipe, this support wheel is installed on the slide block that can slide up and down, thereby can control the advance and retreat cutter automatically.This structure only at upper and lower to being provided with guide wheel owing to have certain clearance between the left and right sides inwall of steel pipe and the knife bar, so cutter can be offset at left and right directions when moving in steel pipe unavoidably, thereby influences the effect of deburring.
The utility model content
The technical problems to be solved in the utility model provides the cutter that a kind of result of use is better removed burr in the ERW, to overcome the above-mentioned defective of prior art.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme: a kind of cutter of removing burr in the ERW, comprise cutter hub and blade, the top and the bottom of described cutter hub are respectively equipped with guide wheel, described cutter hub each side be provided with side guide wheel.
Preferably, described side guide wheel is installed on the spring support.
Preferably, described spring support comprises holds up piece, and the described piece of holding up is connected with cutter hub by bolt, holds up and also is provided with the compression spring between piece and the cutter hub.
The beneficial effects of the utility model are: owing to increased side guide wheel in the left and right sides, make cutter can both form spacing with the steel pipe inwall and guiding at four direction up and down, thereby guarantee that blade contacts with the good of weld seam position, improve the effect of burr in removing, the ERW production of change side, the side of being specially adapted to moulding process.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is a kind of structural representation of removing the cutter of burr in the ERW of the utility model.
Fig. 2 is the partial sectional view at A-A place among Fig. 1.
Among the figure: 1, blade 2, guide wheel 3, side guide wheel 4, cutter hub
5, strut wheel 6, hold up piece 7, wheel shaft 8, bolt 9, compression spring
The specific embodiment
As shown in Figure 1, cutter of the present utility model comprises cutter hub 4 and blade 1, and blade 1 is installed on the cutter hub 4, can contact with the weld seam on the inner wall of welded pipe, to remove the interior burr of commissure.
The top of cutter hub 4 is provided with guide wheel 2, and the bottom is provided with strut wheel 5, and the left and right sides of cutter hub 4 also respectively is provided with a side guide wheel 3.
As shown in Figure 2, piece 6 is held up in one of the each side installation of cutter hub 4, holds up be provided with compression spring 9 between piece 6 and the cutter hub 4, and each holds up piece 6 to be connected with cutter hub 4 by two bolts 8, compression spring 9 is enclosed within on the bolt 8, thus hold up piece 6 can be within the specific limits along the axial activity of bolt 8.Like this, hold up piece 6 and compression spring 9 just to constitute a spring support, side guide wheel 3 is installed on this spring support by wheel shaft 7, and can carry out suitable stretching with spring support, keep in touch with the inwall of assurance with welded tube, play guiding and the spacing effect in the left and right sides, blade can be offset, improve the effect of burr in removing.
Those skilled in the art can understand at an easy rate, and the spring support structure in the present embodiment is not unique, just can implement the utility model as long as can realize the flexible of two side guide wheels, just should be within protection domain of the present utility model.
