Abstract

PURPOSE:To reduce denaturation of property and ensure welding condition of welded part of hollow tube within a solenoid and eliminate deflection by coupling a non-magnetic pipe and magnetic pipe with a frictional pressurizing welding means. CONSTITUTION:A contact pressure between a non-magnetic pipe 17 and a magnetic pipe 18 is kept at the heating pressure P1 under the condition that the pipe 17 being caught by the chuck 66 runs toward the pipe 18 and is placed in contact with it. When such condition is continued for the predetermined heating time T1, the contact portion of non-magnetic pipe 17 and magnetic pipe 18 is heated by the frictional heat and fuses. Thereafter, a contact pressure between the non-magnetic pipe 17 and magnetic pipe 18 is increased and such pressure is set to the upset pressure P2. Due to such increase of pressure, the welded part is pushed out from the pipes 17, 18, forming the burrs 72, 73. After such increase of pressure, the brake 59 is immediately operated, in order to stop the rotation of magnetic pipe 18 being pinched by the chuck 58 in the rotating side. Thereby, a pressurized condition of P2 is maintained for a while even after rotation stops, until the welded part is solidified.

Next, the assembling of the hollow body 15 and the assembling of the kantetsushinbi or bushbin device thereto will be explained. First, the cylindrical elements 17, 18 and the friction welding engine are prepared. Note that the cylindrical elements 17, 18 are cut to a predetermined length so that they will have a predetermined size when they are welded together. Next, operate the pump in the hydraulic system of the friction welding machine (■) to obtain the necessary hydraulic pressure. In addition, a non-magnetic element 17 (for example, 8
TJ8816L) and chuck 5 on the rotation side.
A magnetic element 18 (for example, made of 5US680) is chucked onto the magnetic element 8 . Next, turn on the motor 51 to rotate the rotating chuck 58, and the cylindrical element gripped by it]
Rotate 8. Next, oil is fed into a hydraulic cylinder 67 that moves the chuck 66 on the fixed side forward and backward, thereby moving the chuck mark forward. As it moves forward, the non-magnetic cylindrical element (also called a non-magnetic pipe) 17 that is gripped by the 7th charif becomes a magnetic pipe cylindrical element (also called a magnetic pipe).
It advances towards 18 and eventually comes into contact with it. In the state of contact, the contact pressure between the two is maintained at a heating pressure P1 as shown in FIG. This state continues for a predetermined heating time T1. As a result, the contact portion between the non-magnetic pipe 17 and the magnetic pipe 17 is heated and melted by frictional heat. After that, the pressure of the oil sent to the hydraulic cylinder 67 is increased to connect the non-magnetic pipe 17 and the magnetic pipe m.
Increase the contact force. The pressure is the upset pressure shown as P2 in FIG. Due to the increased pressure, the welded portion is forced into and out of the pipe 17.18, forming a barrier 2.73 as shown in FIG. The external pressure immediately activates the player 59 to rotate the chuck 5 on the rotating side.
The rotation of the magnetic pipe J8 held by J8 is stopped.

回転停止後も上記P2の加圧状態をしばらく維持する。Even after the rotation is stopped, the pressurized state of P2 is maintained for a while.

This period of time is continued until the welded portion is stabilized. That is,
In order to prevent the two parts 17 and 18 from separating or the bonding force between the two parts 17 and 18 from decreasing by weakening the pressure, the welding part should be completely solidified and no change will occur even if the force is weakened. The above pressure is maintained at P2 until the state (temperature) is reached where no generation occurs. After starting the pressure increase,
The time T2 until the pressure P is removed is called upset time. After that, when the welded parts of both sides are stabilized by 17 degrees, the above-mentioned pressing force is loosened.

After loosening, the mutually welded magnetic pipe 18 and non-magnetic pipe 17 are removed from the friction welding machine. After that, there are bumps that appear on the inner and outer peripheries of the welded parts. J72.
73 is removed so that both the outer circumferential surface and the inner circumferential surface are smooth. Incidentally, the removal is carried out using any machine such as a grinder or a lathe. Thereafter, the closure body 19 (magnetic yoke) is assembled to the magnetic pipe pair and the non-magnetic pipe 17 that have been integrated with each other. This assembly may be accomplished by welding the parts together using a well-known welding method. After the above-mentioned welding, the Bushbin device and the movable iron core are assembled, and the fixed iron core 16 is inserted into the non-magnetic pipe 17 and the two are connected. That is, the non-magnetic pipe 17 and the fixed iron core 16 are integrated by welding the partial parts using a well-known welding means. Thereafter, the outer peripheries of the welded portions between the magnetic pipe m and the closure body 19 and the welded portions between the fixed iron core 16 and the non-magnetic pipe 17 are polished and finished. After the hollow body 15 (also called a tube assembly) equipped with a movable iron core and a bush pin device is created in this way, it is screwed onto the pulp body 3 shown in FIG. Cover the electromagnet body.

When welding the cylindrical elements 17 and 18 by friction welding as described above, it is best to determine whether the cylindrical elements 17 and 18 are to be fixed to the chuck shell or 66 as follows. . That is, the material forming the cylindrical elements 17°, which has higher hardness at high temperatures (near the point of melting), is fixed to the chuck shell on the rotating side, and the material with lower hardness is fixed to the chuck 66 on the stationary side. It is best to fix it. By doing this, the barrier 2゜73 generated in the welding member due to the frictional pressure application comes out almost evenly on both sides of the cylindrical elements 17 and 18, and the welding condition of the welding member becomes extremely good. This is because that. In addition, when an experiment was carried out with the relationship between the two cylindrical elements 17 and 18 and the two Chigik groups 66 reversed from the above, it was found that Extremely large cracks occur on the side of the element 17 made of magnetic material (SUS816L), while the magnetic material (SU816L) fixed by the chuck 66 on the fixed side
Only a slight crack was produced on the side of the element sliding made of 680), and there was a high possibility that defects would occur in the welded parts.
