Claims

[Claims for Utility Model Registration] 1. A shaping die 1 and a rolling tool 2 for forming the outer surface of the metal tube A that successively communicates with each other in the drawing direction are arranged in a row, and the inner hole of the metal tube A is provided with a shaping die 1 and a rolling tool 2. Shape metal tube A with die 1
a floating plug 4 whose inner surface is formed by pressing with the
A plug 5 is inserted into the grooved metal tube A to create grooves on the inner surface of the metal tube A by pressing it with a rolling tool 2, and both plugs 4 and 5 are interlocked in the axial direction via a connecting tool B. When connected, the floating plug 4 that accompanies the shaping die 1 moves relative to the rolling tool 2 in the axial direction, and the grooved plug 5 and the rolling tool 2 move relative to each other in the axial direction relative to the metal tube A. It has a structure that allows the pinching pressure to be released freely,
On the other hand, an apparatus for processing an internally grooved tube is characterized in that pressing protrusions 2a discontinuous in the ζ circumferential direction are formed on the inner surface of the forming hole of the rolling tool 2. 2. Registration of a utility model characterized in that a finishing die 3 is arranged in a row on the side opposite to the shaping die 1 of the rolling tool 2, and the finishing die 3 can be driven to rotate relative to the metal tube A around its axis. An apparatus for processing an internally grooved tube according to claim 1. 3. The rolling tool 2 is fixed to a rotary body 11 that can be freely driven to rotate around the axis of the metal tube A, and is rotated together with the rotary body 11. On the other hand, an oil passage 25 for cooling and lubricating oil is bored in the casing 10, and the oil passage 2
The utility model registration claim 1 is characterized in that the injection port 23 into the casing 10 of No. 5 is formed to supply oil to the pressed contact portion between the metal tube A and the rolling tool 2. Processing equipment for internally grooved tubes. 4 The connecting tool B includes a spacer 8 disposed between the floating plug 4 and the grooved plug 5, a connecting rod 6 that connects both the plugs 4 and 5 with the spacer 8, and the connecting rod 6.
It is characterized by being composed of large diameter portions 6a and 9 attached to both ends of the insertion end from both plugs 4.5, respectively, and a thrust bearing 7.7 interposed between both plugs 4 and 5. A processing apparatus for an internally grooved tube according to claim 1, 2, or 3 of the utility model registration claim.
