JPS5954497A - Mating device for beveled edge for bent pipe - Google Patents

Abstract

PURPOSE:To facilitate mating of beveled edges and to reduce man-hour by forming a receiving base complying with the bending angle of a curved pipe by means of an opening-closing base which can set angle as desired, a central support base and a pipe support base and adjusting a joint receiving base thereby mating the beveled edges of the bent pipe and the joint. CONSTITUTION:A motor 13a is started to rotate a screw rod 21 and to move a slide box 08 thereby moving central support bases 08-12 to a prescribed positions according to the length of a bent pipe 26a. A hydraulic rotary motor 09 is then started to revolve a gear 10c for revolution so that an opening-closing base 01 is rotated by a set angle by means of a connecting hinge 06a. The support part is adjusted in conformity with the pipe 26a, whereafter the pipe 26a is supported at three points; a pipe clamp 14, a support roll 11a for the bent part and a triangle base 07 for receiving the pipe. The level of the pipe 26a is set by operating jacks 17, 03a, and the pipe 26a is fixed by means of a clamping device 15. The joint 26b is placed on a joint clamping device 25, and the beveled edges of the pipe 26a and the joint 26b are mated with the jack 24c.

Description

[Detailed Description of the Invention] Conventionally, groove alignment of blood vessels and pipe joints (elbows, tees, reducers, flanges, 9Ps, etc.) in the glare as shown in FIG. Or mounted on a pedestal 3' such as a triangular stand 2',
A cradle for the joint is installed on the mating surface side, and after mounting the joint 4° on it, the level setting of both sides and the adjustment of the gap between the groove surfaces are carried out, and the groove alignment work is carried out. Normal 2
Each task is done manually, requiring a large amount of man-hours.

The present invention integrates a curved pipe mounting stand and a joint cradle into one unit, thereby making it possible to mechanize the conventional two-person work into one-person work.Vζ1
It was invented for the purpose of rationalizing money.

Pipe support stand and joint cradle, c! ll configured, the angle opening/closing platform is a song'l! ? An angle opening/closing table that serves as a pedestal and rotates to match any angle of the curved pipe, and can slide after 11f depending on the distance of the curved part from the groove line.

Adjust the level of the Idori device on each of the central support base + '+'-F support base and joint cradle.T: Did you make it easier? Regarding the beveling device for curved pipes, which features a 9-bent pipe mounting stand and a joint holder? The integrated one-bent pipe mounting base can be used at any angle (opening angle O
It is a variable-angle cradle that can mount a curved tube of 0 to 900 mm, and the angle-variable cradle is designed so that the pipe end position (opening line) on the beveling side of one curved tube is always kept at about 11 feet. If it's just a stand.

The groove line changes every time the perpendicular length of the curved pipe changes, making it necessary to move the joint cradle (in this case, the work is difficult due to interference between the curved pipe mounting base and the joint cradle), so the joint cradle The groove alignment for curved pipes is fixed in the original position, the groove line i is constant, and the curved pipe 11ilI is moved! :The device fTk is intended to be provided and can be applied to all devices for groove alignment of all 85 pipes connected to 9 bends 17.
