取りが必要になるから作業効率もよくない。BACKGROUND TECHNOLOGY In general, the above-mentioned cutting operation of a cylindrical member requires a first
As shown in the figure, there is a disc grinder that presses a grindstone blade a rotating at high speed against a cylindrical member (not shown) placed on a main body base c by operating a hand handle b to press the cylindrical member. It is used. However, with this disc grinder, dust is generated during cutting, which not only impairs the working environment, but also has poor working efficiency because burrs form on the cut edges, requiring deburring in post-processing.

特許第164483号）。 In contrast, conventionally, two dies are provided to fit and support the cylindrical member on the axis, and one punch is inserted into the cylindrical member from the orthogonal direction at the end portion where each of these dies abuts within the diameter of the cylindrical member. It is known that the cut-off side of the cylindrical member is disposed so as to be sheared, and as the cylindrical member is cut with the punch, the cutting side of the cylindrical member is moved in a different position with the die on one side.

1198156号）。 In addition, it is equipped with three cutters whose cutting edges abut against the cylindrical member from different directions within an angle range of 120°, and by equipping each cutter with a frame that rotates, the three cutters can be rotated together and cut into a cylindrical member. It is also known to cut parts (UK patent no.
No. 1198156).

つて装置全体が大型にならざるを得ない。 In addition, in the latter type, each cutting edge is
Since a cutter is provided that contacts the cylindrical member within an angular range of 120°, there is a risk that uncut portions may be left when the cylindrical member is pressed with this cutter. Therefore,
This cutting device is constructed in a rotary and traveling type, and the entire device must be large in size.

る。Function: This cutting device for cylindrical members is equipped with a plurality of pairs of punches that move forward or backward in synchronized relative positions in a direction orthogonal to the axis of the die, and each pair of punches is replaced and driven. Since the cylindrical member is pressed, there is no generation of dust, burrs, burrs, etc., and bending moment can be avoided from acting on the die that supports the cylindrical member that is the object to be cut. Also,
Since at least one of the adjacent punches has a cutting edge that cuts the cylindrical member beyond the end of the cutting allowance for cutting the cylindrical member, a plurality of pairs of punches are used in each pair. By simply exchanging and driving the punches each time, the cutting edges of the punches do not interfere with each other, and the cylindrical member can be cut without leaving any uncut parts.

ことができる。 In the cutting device for cylindrical members constructed in this way, after the blade A, which is the object to be cut, is inserted and supported on the axis of the die 1, the punch plate 6 is moved downward, and the cam 5 clamps the clamp jaws 3a, 3b. Press to support blade A with clamping pressure. At the same time, the blade A is pushed off by the punches 2a, 2b, 2c, and 2d, which are pressed in pairs by the cams 4a, 4b, 4c, and 4d. When the cams 4a, 4b descend, the left and right punches 2a, 2b are first pressed by the convex surfaces 40a, 40b of the cams 4a, 4b and are driven in shear, and as the cams 4a, 4b further descend, the left and right punches 2a, 2b A pair of punches 2a, 2b are connected to the concave surfaces 41 of the cams 4a, 4b.
At the same time when the cams 4a, 4b are fitted into the cams 4c, 41b and moved backward, the lower sides of the cams 4a, 4b than the convex surfaces 40a, 40b abut and press the cams 4c, 4d.
c and 4d are moved toward each other. With this movement, the lower punch 2d moves upward, and as the punch plate 6 moves downward, the upper punch 2c moves closer to the die 1, and the lower punch 2d synchronizes to shear the blade A. . When the punches 2a, 2b, 2c, and 2d are driven in shear for each pair,
Since at least one of the adjacent punches cuts the blade A beyond the edge of the cutting allowance for cutting the blade A with the punch on the other side, there is no uncut edge, and the cutting edges of the adjacent punches are Since there is no interference, the blade A can cut smoothly. Also, since each pair of opposing punches 2a, 2b, 2c, and 2d shear the blade A synchronously toward the center of the die 1, the outer periphery of the blade A, that is, the outside in the radial direction, is free of burrs. Burrs can be prevented and there is no risk of cutting one's hand when handling the blade A after cutting.
In addition, the blade A is attached to each punch 2a, 2.
A pair of punches 2a, 2b, which are driven synchronously by the shearing force applied to the die 1 when shearing with
2c and 2d, and no bending moment acts on the die 1, so that the mechanical part for fixing the blade A can be equipped with a simple structure.

きる。 In addition, in the embodiment described above, the cylindrical blade A
The explanation was based on the case of cutting the punch 2.
By changing the shape of the cutting edge according to the shape of the cylindrical member to be cut, it can be applied to cutting cylindrical members of oval, square, or other appropriate shapes.
Moreover, instead of equipping two pairs of punches via a die, three or more pairs can be arranged with the cutting edges of each pair facing each other. These pairs of punches can also be constructed so that each pair of punches can be interchanged and moved forward or backward by a drive cylinder.
Furthermore, each punch is not limited to the case where it slides on the front end surface of the die 1, but can be arranged so as to shear the blade A by coming into contact with the axis of the die 1.

In addition, since no bending moment acts on the die, it is possible to equip a mechanical part with a simple structure for supporting the object to be cut. In addition, since the punch on one side of the adjacent punch has a cutting edge that cuts the cylindrical member beyond the end of the cutting allowance for cutting the cylindrical member, it is possible to accurately cut the cylindrical member without leaving any uncut parts. Since the pair of punches are replaced and driven for each pair, the cylindrical member can be cut smoothly without the cutting edges of adjacent punches coming into contact with each other.
