Is located rearward (above in the figure) from the first forward position D1 (see FIG. 9),
0, 120 are spaced apart from each other, whereby the clamping means 130, 130 are spaced apart from each other.

Next, the rotation of the cam board C1 causes the advance / retreat member 141 of the advance / retreat means 140 to move forward (down in this example).
Then, as shown in FIG. 9, when the advance / retreat member 141 advances to the first advance position D1, the outer operating members 176 and 176 of the operating members 175 and 175 of the cam mechanism 170 are inclined by the inclined surface 176a and the slide block 120 is moved. , 120 are pushed inwardly, and the slide blocks 120, 120 move (forward) inward (clamp direction). At this time, the holding means 130 attached to each of the slide blocks 120, 120,
130 also moves inward at the same time, so that the holding means 130, 130 come close to each other and the holding means 13
The tube T is held between 0 and 130 in the short diameter direction.

After the tube T is held, the reciprocating member 141 further moves forward, as shown in FIG.
The cutting means 150 attached to the reciprocating member 141 advances through the cutting means insertion gap between the slide blocks, whereby the tube T held and held by the holding means 130, 130 is cut by the cutting means 150. You.

Subsequently, when the reciprocating member 141 further moves forward, as shown in FIG. 11, the mounting block 151 for attaching the cutting means 150 to the reciprocating member 141 is moved to the side of the reciprocating member of the pressing means 160 (in FIG. ), And the pushing means 160 is pushed forward by the mounting block 151 by the further advancement of the reciprocating member 141, so that the pushing means 160 moves forward. As a result, the pressing portion 161 of the pressing means 160 enters the pressing means insertion gap S2 of the holding means 130, 130, and the pressing portion 161 has an outer surface on one side in the long diameter direction of the terminal portion Ta of the flat tube T (the long diameter in the drawing). Terminal processing for compressively deforming the upper side outer surface (Tx1) is performed.

Then, as the advancing / retreating member 141 of the advancing / retreating means 140 retreats (ascends in the figure), the slide blocks 120, 120 move outward (retreat) and are separated from each other. Is released, the tube product T2 as shown in FIG.
Is obtained. When the slide blocks 120, 120 move outward due to the retreat of the advance / retreat member 141, the pressing means retreat block 125 moves outward together with the slide blocks 120, 120, and the inclined portion 126 is moved. By sliding with respect to the inclined step portion 163 of the pressing means 160, the pressing means 160 moves backward (ascends in the figure).

If the end processing and the cutting processing of the tube are performed by using the cutting and terminal processing apparatus 110, the same effect as in the case of using the cutting and terminal processing apparatus 10 of the above embodiment can be obtained. In other words, it is possible to perform tube cutting processing and terminal processing with one apparatus 110, thereby realizing reduction in both processing man-hours, improvement in both processing efficiency, and reduction in equipment cost.
In addition, the installation space required for the apparatus for both processes can be reduced. In addition, the cutting and terminal processing device 110
Since the cam mechanism 170 mechanically associates the reciprocating operation of the reciprocating member 141 (the elevating operation in the illustrated example) with the operation of other components, the terminal processing and the cutting process are performed by the reciprocating operation of the reciprocating member 141. It can be performed by a series of operations. Therefore, only one drive source (the motor for rotating the cam board C1 in the illustrated example) for operating the advance / retreat member is required for the device 110, and the mechanism for controlling the operation of the device 110 can be simplified. There are advantages.

24, the distance between the outer block 221 and the inner block 222 is maintained.
The inner block 222 also moves inward while the 222 is separated.

After the tube T is held, the advance / retreat member 251 further advances (in this example, descends), and as shown in FIG. 14, when the advance / retreat member 251 reaches the second advance position D2, the second cam Notch means 240 by the action of the mechanism
Performs a terminal process of moving (moving) the tube T toward the tube T along the sliding direction Y to form a cutout portion Tc at one side (the lower portion in the illustrated example) of the tube T in the major diameter direction. More specifically, when the advance / retreat member 251 moves forward, the divided slide block 2
Rotating member 27 which is pivotally mounted on outer block 221 of 20
As the first and second members 271 are pushed inward by the front inclined surfaces 276b and 276b of the outer operation members 276 and 276, the outer block 221 moves inward (advances) and approaches the inner block 222. . As a result, the notch means 240 provided in the outer block 221 enters the notch means insertion hole 235 of the front (left side in the figure) holding means 230, and the notch means 240 is inserted into the longitudinal direction of the tube T. A notch is made by penetrating (punching) the side flange portion Tb in the short diameter direction.

After the end processing, the reciprocating member 251 further advances, as shown in FIG.
The cutting means 260 attached to 51 advances through the cutting means insertion gap between the slide blocks. As a result, the tube T held and held is cut by the cutting means 260 at a portion where the cutout portion Tc is formed (in this example, substantially at the center of the portion).

Then, the respective slide blocks 22 are retracted by retreating (moving up in the illustrated example) of the advance / retreat member 251.
When the tube 0, 220 moves outward (retreats) and separates, and the holding of the tube T is released by the holding means 230, 230, a tube product T3 as shown in FIG. 19 is obtained. When each of the slide blocks 220, 220 moves outward due to the retreat of the advance / retreat member 251, first, the outer side block 2
The inner block 22 is driven by the urging force of the urging means 224.
2, the notch means 240 provided on the outer block 221 also moves outward (retreats).

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.

In this example, the cutting process is performed after the terminal process. However, the present invention is not limited to this, and the terminal process may be performed after the cutting process. In this case, it is necessary to change the stroke of the cutting means 260, the length of the cutting means 260, the positions of the rear inclined surfaces 276b and 277b of the outer operating member 276 and the inner operating member 277, and the like.

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.

Further, if the slide block is divided along the longitudinal direction of the tube and the cutting means insertion gap of the cutting means is provided between the slide blocks in the longitudinal direction, the tube can be reliably secured. In this state, cutting can be performed at an accurate position, and the processing accuracy is improved.
