Abstract

PURPOSE:To efficiently from flanges in a uniform shape and with uniform strength by putting a punch and a secondary forming spinning roll concentric with the punch in successive operation, and thus performing automatic accurte centering. CONSTITUTION:A hydraulic cylinder 15a is put in operation to press a primary forming punch 4 with a piston 15, and then a conical tip part 4a is pressed in a pipe end part P', which is forced to spread at its intermediate part in a flare shape. Then, the punch 4 is moved back, and the whole of an outer body 8 is moved forth along a guide wall 10, thereby a secondary spinning roll 6 into press contact with the flare-shaped intermediate spread part. A hollow shaft 1 is driven by a motor 11 to turn at a high speed, and thus the outer body 8 is further pressed through a piston 16 to apply pressing force to the roll 6. Consequently, the flare-shaped intermediate spread part spreads completely by plastic deformation at right angles to a pipe shaft in press contact with die flanks 18a and 18a' of a pipe clamping die, thus forming a prescribed flange united with a pipe.

DETAILED DESCRIPTION OF THE INVENTION This invention relates to a molding method and a molding machine for integrally molding a flange for connection on a pipe to be connected to the end of a pipe body such as a copper pipe.

The end of the tube is expanded in two steps: intermediate expansion and complete expansion. 5:
It is well known that the molding process is carried out by molding /ji, but conventionally, the equipment for the primary process and the equipment for the secondary process were configured separately.
In order to carry out the forming process while moving the tube, the reference lines are made to coincide with each other during the next and secondary processes, or when moving from the next process to the secondary process. This method has the disadvantage of lacking in productivity because it requires a laborious process to accurately perform so-called centering. In addition, if this centering is inaccurate, there will be non-uniformity in the shape and surface wear of the molded plunge, which will impede the connection and strength of the pipe to be connected, resulting in product loss resulting in defective products. I couldn't escape it.

The end of a predetermined length of pipe is fixed so as to protrude from the pipe clamping die, and a primary molding pin is formed on the conical part at the end, which has a diameter larger than the pipe diameter, and is located relatively on the extension line of the central axis of the pipe. Next, instead of the above-mentioned punch, an engineering molded steel hole placed concentrically with the punch is brought into pressure contact with the above-mentioned opening, and by applying pressure while sliding and rotating, a flare-like shape is formed. The intermediate expanding part is completely expanded in the direction orthogonal to the tube axis that is crimped to the mold wall surface of the tube clamping type to form an integrated flange. It is possible to efficiently form a 5-inch (accurate and uniform) 5-inch by sequentially acting on a fixed tube concentrically with the central axis of the tube.

As described above, the present invention uses a primary forming pump and a secondary forming tool to perform flange forming by sequentially acting on a fixed tube with the lever 1 concentrically with the central axis of the tube. Because of this, the centering is always determined automatically and accurately, and the secondary forming line is 0.
- Since the surface of the flange 5 is shaped at the same time by sliding rotation and pressure by the wheel, it has the remarkable feature that excellent flanges with uniform shape and uniform strength can be formed extremely efficiently, contributing to this industry. However, it is very internal.

(2) The tube end of the fixed tube is flared in the middle, and then completely expanded in the direction perpendicular to the tube axis, thereby achieving 5. It is a molding machine that molds all kinds of products. +il A hollow main shaft having a hollow hole in the central axial direction is inserted into an outer shell that can be moved back and forth along the wall of the guy F by the same stone so as to be rotatable at high speed. For intermediate expansion of the conical tip part whose diameter is larger than the inner diameter of the continuous pipes, insert the next molded hinge freely forward and backward, and attach the secondary molded hinge for complete expansion to the front part. The supported O-ru support plate is placed in the center of the front of the hollow spindle spatula r portion, and this is pushed open by the advance of the fire-forming punch, and the tube end section of the punch is press-fitted into the needle. A forming mechanism whose upper end is hinged to the head part so that the track can be adjusted to the extent that the molding mechanism can be moved. It consists of a tube fixing structure consisting of a tube holding type that fixes the tube by protruding the tube end of a predetermined length required for 5-inch molding (on the central axis extension line of the 111 hollow main shaft). fiiiil said molding machine #j,! : The tube fixing mechanism was configured relative to the base with a predetermined interval. A tube end flange made of cedar.
