As said to perform terminal processing by the device, cutting processing and terminal processing were performed in this order.
Often, each is performed by a separate device. Therefore, the number of steps required for the cutting process and the terminal processing is large and the working efficiency is low, and the device for the cutting process and the device for the terminal processing must be prepared separately, resulting in an increase in equipment cost. is there. In addition, if both devices are prepared separately, there is a problem that an installation place for both devices must be secured.

述のカム機構を説明する際に詳述する。The advancing / retreating means 40 is perpendicular to the sliding direction Y of the slide block and the longitudinal direction X of the tube with respect to the holding means 30 (vertical direction in the illustrated example).
It is arranged so as to be able to move forward and backward along Z (to be able to move up and down in the illustrated example). The reciprocating means 40 of the embodiment includes a reciprocating member 41 formed of a plate-like body, an operating member 65 provided on a front surface (a lower surface in the illustrated example) of the reciprocating member 41, and advancing and retreating the reciprocating member 41 ( In the illustrated example, an advancing / retracting device is provided for moving up and down. In addition, the advancing / retreating member 41 is disposed on the base 11 via a rod member (not shown) so as to be able to advance and retreat. An eccentric cam driven by a motor or the like, a cylinder device, an actuator, or the like can be used as an advance / retreat device for moving the advance / retreat member 41 forward and backward. In this example, the advance / retreat member 41 moves forward and backward by a groove cam mechanism C provided behind (in the illustrated example, above) the advance / retreat member 41.

As can be more easily understood from FIG. 7, the groove C1a of the cam disc C1 is formed by the rotation axis Cs of the cam disc C1.
The eccentric member is formed eccentrically with respect to the cam plate C1, and as the distance between the rotation axis Cs of the cam plate C1 and the advancing / retreating member 41 increases with the rotation of the cam disk C1, the advancing / retreating member 41 advances with respect to the holding means 30 (in the example shown in the figure). Then, as the distance between the rotating shaft Cs of the cam board C1 and the advance / retreat member 41 becomes smaller, the advance / retreat member 41 retreats (increases in the illustrated example) with respect to the holding means 30. The operation member 65 will be described in detail when describing a cam mechanism described later.

る。When the end processing and the cutting of the tube are performed by using the cutting and terminal processing apparatus 210, the same effect as in the case of using the two cutting and terminal processing apparatuses 10 and 110 described above can be obtained. In other words, it is possible to cut and end the tube with a single device 210, thereby realizing a reduction in both processing man-hours, an improvement in both processing efficiencies, and a reduction in equipment costs. Required installation space can be reduced. In addition, the cutting and terminal processing device 210 mechanically associates the advance / retreat operation (elevation operation in the illustrated example) of the advance / retreat member 251 with the operation of other constituent members by the cam mechanism 270, so that the advance / retreat member 251 advances / retreats. By the operation, the terminal processing and the cutting processing can be performed by a series of operations. Therefore, only one drive source for the device 210 (a motor for rotating the cam board C1 in the illustrated example) is required to operate the reciprocating member, and the mechanism for controlling the operation of the device 210 can be simplified. There are advantages.

Therefore, the number of steps for both processes can be reduced, both processes can be performed efficiently, the equipment cost can be reduced, and the installation space required for the device is also reduced. In addition, in the cutting and terminal processing using the cutting and terminal processing device, unlike the conventional processing of cutting the tube at a terminal end portion that is formed by assuming the terminal shape of the product at the time of forming the tube, unlike the processing of processing. There is no loss of freedom. In particular, the device according to the first aspect of the present invention is suitable for forming a shape by compressively deforming the outer surfaces of both ends in the longitudinal direction of the end portion of the tube. The apparatus according to the third aspect of the present invention is suitable for forming a notch by forming a cutout on one side in the long diameter direction of the end portion of the tube.
