In addition; in the present embodiment; protection portion 6 is the planar plate shapes (Japanese: writing board shape) extended from base portion 2, and as shown in (a) of Fig. 2, the vertical sectional shape of protection portion 6 is the shapes of the arc-shaped of giving prominence to towards the outer edge side of base portion 2.In this case, when the circumferential R making cutter 1 along stacked pipe 10 rotates, protection portion 6 is easy to rotate between pipe 11 and skin section 12 in stacked pipe 10.But the vertical sectional shape of protection portion 6 is not limited to this.Such as, protection portion 6 can be the pole shape with circular vertical sectional shape component, there is the component etc. of the planar plate shape of oval vertical sectional shape.That is, the shape of protection portion 6 can suitably be changed.
Next, the method using cutter 1 to remove a part for skin section 12 from stacked pipe 10 is described.
With reference to Fig. 1, the 1st operation is operation cutter 1 being pressed into stacked pipe 10 and blade 5 being aimed at skin section 12.In detail, as direction of the arrows shown in fig, the protection portion 6 of cutter 1 is made to be pressed into by the length direction end face 10e of cutter 1 towards stacked pipe 10 between pipe 11 and skin section 12 in alignment with in stacked pipe 10.Now, because the protection portion 6 of cutter 1 is separately inserted between interior pipe 11 and skin section 12 by stacked pipe 10 between pipe 11 and skin section 12, thus cutter 1 can be pressed into incorporating section S.As shown in (a) of Fig. 3, till the base portion 2 that the press-in of cutter 1 can proceed to cutter 1 is contacted with the length direction end face 10e of stacked pipe 10.In addition, in the present embodiment, as shown in (a) of Fig. 3, will the inner edge of the arm 3 of blade 5 be configured with and be set as the size slightly larger than the diameter of stacked pipe 10 across the size of central axis O between the inner edge of the other arm 4 of the contrary side of this arm 3.
2nd operation be by a part for the skin section 12 of stacked pipe 10 circumferentially R cut off operation.In detail, as shown in (b) of Fig. 3, the arm 3 of cutter 1 is pressed into towards the skin section 12 of stacked pipe 10 near blade 5, cuts off a part for skin section 12 and after forming crack, cutter 1 rotated along the circumferential R of stacked pipe 10.
In detail, first the skin section 12 of the arm 3 of cutter 1 towards stacked pipe 10 is pressed into, make arm 3 with near the linking part of arm 3 and base portion 2 for basic point occurs bending and deformation.Thus, as shown in (b) of Fig. 3, the blade 5 of cutter 1 can cut off a part for the skin section 12 of stacked pipe 10 and form otch in skin section 12.In the present embodiment, when cutting off skin section 12, even if blade 5 is cut darker, also because blade 5 contacts with protection portion 6, therefore, it is possible to prevent blade 5 from damaging the outer surface of interior pipe 11.Then, if the state certainly having cut out otch makes cutter 1 rotate, then only skin section 12 position that is approximately Δ X in the size of the length direction end face 10e apart from stacked pipe 10 is cut to tubular along the circumferential R of stacked pipe 10.In the present embodiment, owing to being formed as arc-shaped by the shape of the cutting edge 5a by blade 5, the resistance resulting from blade 5 can be reduced, easily the circumferential R of skin section 12 along stacked pipe 10 be cut off.And, by after a part for skin section 12 is cut to tubulose, directly under the state of arm 3 press-in, cutter 1 is pulled out from stacked pipe 10, as shown in (a) of Fig. 4, under the state that interior pipe 11 is stayed stacked pipe 10, only can remove the skin section 12 of tubular.
So, as long as use the cutter 1 of present embodiment, by means of only making the length direction end face 10e of stacked pipe 10 contact with the base portion 2 of cutter 1, and cutter 1 is rotated along the circumferential R of stacked pipe 10, just can under the state that interior pipe 11 is stayed stacked pipe 10 circumferentially R only cut off skin section 12.Thus, as long as use cutter 1, the local that the number of working processes also can remove the skin section 12 of stacked pipe 10 just can be reduced.
In addition, in epidermis cutter in the past, when the skin section 12 of stacked pipe 10 is circumferentially cut off, need to cut off along mark, and in the present embodiment, by making the length direction end face 10e of stacked pipe 10 contact with the base portion 2 of cutter 1, scheduled owing to cutting off size, therefore do not need to mark.But the cutter 1 of present embodiment also can not make the length direction end face 10e of stacked pipe 10 and the base portion 2 of cutter 1 use contiguously.In addition, after the notch that the skin section 12 of stacked pipe 10 defines vertically, removal has skin section 12 of notch as in the past, if not exclusively align with the position of blade in the position of the axial length of notch, then remain cut channel in the skin section 12 residuing in stacked pipe 10 sometimes.To this, as long as use the cutter 1 of present embodiment, owing to not needing to form the notch along the central axis O of cutter 1, therefore, skin section 12 aesthetic property eliminating the stacked pipe 10 after a part for skin section 12 is excellent.
And, in the cutter 1 of present embodiment, with as shown in (a) as Fig. 4 when stacked pipe 10 eliminates skin section 12 a part of in pipe 11 length direction exposed amount Δ X and interior pipe 11 and in connecting pipe 11 connecting elements 20 between connection measure equal mode and be configured with blade 5 relative to arm 3.In this case, consistent with the connection amount of connecting elements 20 to the distance, delta X of blade 5 from base portion 2 by making, and do not need the operation describing mark line.Thus, as shown in (b) of Fig. 4, stacked pipe 10 is connected to connecting elements 20 with can not producing fold.
In addition, as (a) of Fig. 3, Fig. 3 (b) shown in, the cutter 1 of present embodiment, except having arm 3, also has the other arm 4 forwards extended from base portion 2, and these other arms 4 are configured at the outside of the skin section 12 of stacked pipe 10 together with arm 3.In this case, due to easily and reliably cutter 1 can be kept, therefore, it is possible to easily cut off skin section 12 by holding other arm 4.In addition, arm 4 is at least one in addition.When the other arm 4 being located at base portion 2 is one, this other arm 4 can be configured at the position across the central shaft O side contrary with arm 3.Or cutter 1 can omit other arm 4, protection portion 6.That is, cutter 1 of the present invention can be the component be made up of at least base portion 2, arm 3 and blade 5.
