Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for finish cutting the edge of a continuously running skelp, and in particular a device for shaping and cutting the edge so that the cutting surface of the edge is cut into a sloped state that maintains a predetermined angle. The present invention relates to an angle adjustment device.

Forge welded pipes or electric resistance welded pipes are made by curving the skeleton into a cylindrical shape and joining the left and right edges together and forge welding or welding them to form the pipe body. It is necessary to increase the number of people.

For this purpose, if the edges are shaped on a cut surface perpendicular to the sculpt surface, then when the skelp is made into a cylindrical shape and the edges are brought into contact with each other, it is necessary to Since they have the same dimensions, the butting condition is not uniform, and there is a drawback that an extreme raised portion (bead) is generated on the inner diameter side of the joint.

Therefore, in order to eliminate the above-mentioned drawbacks, it has been conventional practice to shape the edges so that they form slopes at a predetermined angle with respect to the skelp surface in order to prevent excessive bulges from occurring at the joints. ing.

The purpose of the present invention is to determine in advance through calculations and experiments 75) that when this skelp is formed into a cylindrical body, there will naturally be a dimensional difference between the outer circumference length and the inner circumference length due to the presence of wall thickness. The object of the present invention is to provide an angle adjusting device for a cutting tool that cuts the edge of a skelp at a predetermined angle so as to obtain this difference in circumferential length.

The device of the present invention is installed in a support box of a scalp and edge cutting device, and the support box can be moved up and down and adjusted in the width direction of the plate, and can be moved horizontally and horizontally. They are arranged symmetrically so that they can engage the edges simultaneously.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The configuration of the apparatus of the present invention will be specifically described below with reference to the accompanying drawings.

Figures 1 and 2 (As shown, two brackets 1 are integrally formed in a support box (not shown), and swing by supporting the upper part of the hanging holder 2. Holds possible.

This hanging holder 2 is formed as a vertically elongated frame, and a block-shaped cutting tool mount 3 is held within the frame so as to be movable up and down.

'That is, the cutting tool mount 3 is screwed onto a screw shaft 21 that is vertically installed on the hanging holder 2, and is moved vertically by the rotation of this screw shaft 21. It is designed to move up and down along a guide frame 22.

Further, the hanging holder 2 is provided with a scale plate 32,
A pointer 33 associated with this is fixed to the cutting tool mount 3 so that the position of the cutting tool 31 can be accurately grasped.

The screw shaft 21 is rotated by a motor 23 fixed to the bracket 1.

The rotation of the motor 23 is transmitted to the horizontal rotating shaft 26 by gears 24.25, and then transmitted to the screw shaft 2 via the bevel mechanism 27.
1 can be transmitted.

The cutting tool mount 3 has a part of the block body to which the cutting tool 31 is attached, and the tip of the cutting edge of the cutting tool 31 is protruded (see Fig. 3), so that it is not interfered with by the presence of the hanging holder 2. It is designed to be able to engage the edges of the skelp.

The cutting tool 31 has a vertically elongated cutting edge and is installed vertically, but in this device, the tool 31 is not necessarily installed vertically, and the lower end of the tool is slightly tilted toward the running direction of the skelp, as shown in Figure 2. Install the entire tool at an angle so that it can be moved.

This is extremely effective in making the chips fall smoothly.

An angle setting mechanism 4 is provided at the rear of the hanging holder 2.

As shown in FIGS. 3 and 4, this mechanism 4 is fixedly installed at a position where it engages with the back surface of the cutting tool mount 3.
Rotate the handle 41 to move the push screw shaft 42 forward;
This allows the tool mount 3 and the hanging holder 2 to be tilted together and held at a desired angle.

Therefore, as shown in FIG. 3, in the hanging holder 2' held obliquely, the cutting edge line of the cutting tool 31' is also inclined at a predetermined angle, and the edge of the skelp 5 is It becomes possible to form it on the cut surface.

Note that an angle plate 28 is provided on the upper part of the hanging holder 2, and a pointer 29 mated to the angle plate 28 is fixed to the bracket 1 side), so that the inclination angle of the hanging holder 2 can be accurately grasped. There is.

Further, an arcuate groove 12 as shown in FIG. 5 is provided in the extension part 11 of the debracket, and an angle fixing screw 13 screwed into the hanging holder 2 is provided.

When the inclination angle of hanging holder 2 is determined, fixing screw 1
3 can be tightened to fix the tilted posture of the hanging holder 2.

The device of the present invention is installed symmetrically with respect to both edges of the skelp, and the cutting begins after adjusting the position to a predetermined board width dimension and also adjusting the vertical position. When the cutting tool 31 becomes worn as cutting progresses over time, the motor 23 is driven to slightly adjust and rotate the screw shaft 21 to shift the position of the tool mounting base 3 upward or downward, thereby causing the cutting blade to operate. You can change the position to have the same result as byte swapping.

Furthermore, the operating position of the cutting blade can be changed by constantly moving the cutting tool up and down during cutting.

In this case, since the cutting tool mount 3 moves up and down within the tilting hanging holder 2, continuous cutting is performed without any change in the joining angle between the cutting tool and the edge of the skelp.

According to the cutting device equipped with the angle adjustment device of the present invention, the angle can be adjusted very easily and quickly not only during setup changes but also during cutting operation, so that shaping with a predetermined angle formed on the abutting surface of the edge is possible. This makes it possible for the joint surfaces to be parallel or very close to parallel, which enhances the forging or welding effect and improves yield.

In addition, it is possible to prevent the occurrence of extreme bulges on the inside, resulting in improved quality, and since the tool bit can be easily replaced, productivity is also improved.
