いた。This solid-phase bonding is performed by abutting the end surfaces of a pair of objects to be bonded, and heating and pressurizing the bonded portion to a bonding temperature. Such solid-phase bonding has the advantage of not causing a decrease in mechanical strength due to changes in metal structure, unlike bonding by welding. Conventionally, when long objects to be welded are to be joined in the field, the parts near the ends of the objects to be welded are held by chucks, and pressure is applied to the objects through the chuck along the axial direction of the objects. was.

変形を防止し接合するようにした園相接合装置を実願昭
５６−４３６４４号として既に出願している。However, with such means, there is a point where the portion of the object to be joined where the grains are damaged between the pair of chucks is inevitably deformed by applying pressure to the object to be joined. Therefore, the present applicant covered the joint part of a pair of workpieces that are pressurized in the axial direction through a chuck with a deformation restraint part, and also installed the joint part in the deformation restraint part in the direction of the koji of the workpieces. An application has already been filed as Utility Model Application No. 56-43644 for a welding device in which a push tool is provided to apply pressure in a perpendicular direction to prevent deformation of the parts to be joined.

相接合装置を提供しようとするものである。However, since the chuck equipped with the push tool is heated to the bonding temperature, the objects to be bonded are deformed within the deformation restraining portion, and it is difficult to remove the objects to be bonded from the chuck after bonding. This invention was made in view of the above-mentioned circumstances, and its purpose is to minimize the deformation of the objects to be joined, and to provide a solid phase that allows easy removal of the objects after joining. The present invention aims to provide a joining device.

明する。In the figure, 1 is a base, and a first chuck 2 and a second chuck 3 are installed at both ends of the base 1 in the longitudinal direction, and between these, the first and second chucks 2 are installed.
, 3, and a deformable restraint pick-up device 4 is provided. Since the first and second chucks 2 and 3 have the same structure, to explain only one of them, they consist of an upper chuck 6 and a lower chuck 7 that restrain the workpiece 6, and these chuck pressurizing cylinders. 8 to open and close. Further, the upper and lower chucks 6 and 7 are connected to an axial pressure cylinder 9 that presses the welded portion 5 in the axial direction, and the axial pressure cylinder 9 allows the welded parts to be held by the upper and lower chucks 6 and 7. The object 5 is pressurized in all directions. In addition, the above deformed restraint vulgar smell 4 is the upper vulgar smell 10.
It is divided into two parts: a and a lower jig 10b, and the joint part 5a of the pair of objects 5.5 to be joined is accommodated between these parts. The upper part 10a is provided with an upper cylinder 11 that presses it toward the lower jig 10b. In addition, a through hole 12 is drilled in the lower jig 10b, and this through hole 12
A pressing odor 14 is inserted in the holder 14, which is moved up and down by a lower sill 13. Next, the operation of the above embodiment will be explained.

開放する。First, a pair of objects 5, 5 to be welded are placed between the first chuck 2 and the second chuck 2.
The upper part 10a of the part 4 is clamped by the chuck 3, and the joint part 5a adjacent to the end face is deformed and restrained.
and the lower profane smell 10b. Next, after placing the entire bag counterfeit in a vacuum, inert gas or reducing gas atmosphere, the objects 5, 5 to be joined are heated by heating the deformation restraint jig 4.
heat up. When the workpiece 5.5 reaches a certain temperature in this state, the workpiece 5.5 is heated by the axial pressure cylinders 9, 9.
, 5 in the vertical direction, the push tool 14 is pushed up by the lower cylinder 13 of the deformation restraint jig 4, and the joint portion 5a of the objects 5, 5 to be joined is pressed in a direction perpendicular to the vertical direction and held for a certain period of time. . In this way, when the object to be welded 5.5 is pressurized in the opposite direction, the joint 5a tries to deform in the direction perpendicular to the direction, but the joint 5a is contained by the deformation restraining jig 4. Since it is pressed by the pushing tool 14, deformation is suppressed, and the pushing tool 14 increases the pressure bale force on the end surface of the joint portion 5a, resulting in high-strength solid phase welding. In addition, after joining, the objects to be joined 5, 5
When taking out the object, the first and second chucks 2 and 3 are opened, and the upper cylinder 11 of the deformable restraint pick-up tool 4 is also opened.

きな加圧力が加わり、高強度に固相接合される。Then, after opening the upper part 10a and the lower part picking tool 10b, the lower cylinder 13 is operated and the pushing tool 14 is pushed upward, and the objects 5, 5 to be welded are taken out from the deformation restraint jig. Note that if the bonding atmosphere is in the air or the objects to be bonded 5 are oxidized even in an inert gas atmosphere, the deformation restraint jig 4 is pressurized and the first. After being pressurized in the axial direction by the second chucks 2 and 3, it is heated, and when the bonding temperature is reached, the lower cylinder 13 is used to press the odor 14.
The bonding may be performed by applying pressure and holding it for a certain period of time. As explained above, the present invention provides a deformation restraint jig that can be divided and covers the joint portion of the workpieces between the first and second chucks that apply pressure to a pair of workpieces in the axial direction. Since the pick-up tool is equipped with a pusher that presses the joint in a direction perpendicular to the axial direction of the object to be welded, a large pressing force is applied to the joint by the pressing force in the direction and the pressing force in the direction perpendicular to the direction. is added to achieve high strength solid phase bonding.

る。Further, the chuck that holds the objects to be joined is thermally isolated from the deformation restraint jig that heats the objects to be joined, and the joint portion is covered by the deformation restraint and deodorization, so that deformation is suppressed. According to the inventor's experiments, when copper is conventionally joined with 55 pins, the deformation rate in the thickness direction is 9 to 18.
%, but according to the present invention, it was possible to suppress it to 6% or less. Furthermore, since the deformation restraining jig is made divisible and a push tool is provided, there is an effect that the objects to be welded can be easily taken out after welding.
