【Example】

 A configuration of an embodiment of a strainer according to the present invention will be described below with reference to the accompanying drawings. First, the shape of one embodiment of the strainer 12 formed by the strainer processing machine 10 will be described with reference to FIGS. 1 to 3.

As shown in FIG. 1, the strainer 12 is formed with a strainer body 14 made of a pipe extending in one direction, and a state in which the strainer body 14 penetrates the strainer body 14 in the thickness direction, Further, it is provided with a plurality of cut grooves 16 extending along the central axis thereof. Here, the cut groove 16 of the strainer 12 in this embodiment extends along the central axis of the strainer body 14 with a predetermined length as shown in the expanded state in FIG. They are arranged along a certain pitch. More specifically, in this embodiment, the cut grooves 16 are arranged in a total of 8 rows at every 45 degrees in the circumferential direction of the strainer body 14, and the size of each cut groove 16 is the width. The length (that is, the length along the circumferential direction) is set to about 1 mm, and the width (that is, the length along the central axis) is set to 100 mm. Further, the arrangement pitch along the central axis is set to 200 mm. Further, the cut grooves 16 corresponding to the even-numbered rows and the cut grooves 16 corresponding to the odd-numbered rows are set to be nested with each other in the circumferential direction.

By forming the strainer 12 in this way, it is possible to secure a sufficiently large overall opening area (that is, the total area of all the cut grooves 16) formed on the outer peripheral surface of the strainer body 14. Even in this case, the lateral size (that is, the size along the central axis of the strainer main body 14) can be increased and the number of dispositions can be increased, and the width size (that is, the strainer main body) can be achieved. It is not necessary to increase the size of 14 in the circumferential direction). As a result, in the case of forming conventional round holes, in order to make the overall opening area wide, it is unavoidable to make the diameter of each round hole large. Although foreign matter such as gravel may get into the strainer 12, since the width of the cut groove 16 can be maintained in a narrow state, the foreign matter can be effectively prevented from getting into the strainer 12. You will be able to do it.

Further, as shown in FIG. 3, a recess is formed on the inner circumference of one end of the strainer body 14 so as to reduce the thickness thereof by half over the entire circumference. A female screw 18 is threaded on the surface. On the other hand, a recess is formed on the outer circumference of the other end of the strainer body 14 so as to reduce the thickness thereof in half over the entire circumference, and a male screw 20 is threaded on the outer peripheral surface of the recess. There is. The female screw 18 and the male screw 20 are set to be screwed together. In this way, by forming the female screw 18 and the male screw 20 at both ends of the strainer body 14, the second strainer 12B is arranged on one end side of the first strainer 12A, and the first strainer 12A The first and second strainers 12A and 12B can be connected to each other by screwing the female screw 18A on one end side and the male screw 20B on the other end side of the second strainer 12B with each other. Further, the third strainer 12C is arranged on the other end side of the first strainer 12A, and the male screw 20A on the other end side of the first strainer 12A and the female screw 18C on one end side of the third strainer 12C are mutually By screwing, the first and third strainers 12A and 12C can be connected to each other. That is, by constructing one strainer 12 in this way, it becomes possible to connect the strainer 12 until the desired length is obtained. Then, the outer peripheral surfaces of the connected strainer assemblies are smoothly set and brought into a state without any step.

Next, the configuration of the strainer processing machine 10 for processing the strainer 12 will be described in detail with reference to FIG. 4 and subsequent figures.

As shown in the overall structure of FIG. 4, the strainer processing machine 10 has a base 22 and a pipe material 24, which is disposed on the base 22 and serves as a material for the strainer 12, in a rotating manner. A clamp mechanism 26 for clamping, a rotating mechanism 28 for rotationally driving the pipe material 24 clamped by the clamp mechanism 26, and a cut for cutting the pipe material 24 clamped by the clamp mechanism 26. The mechanism 30 is roughly provided and configured. The pipe member 24 has female threads 18 and male threads 20 formed on both ends thereof in advance.

First, the clamp mechanism 26 for rotatably clamping the pipe member 24 will be described in detail with reference to FIGS. 5 and 6. The clamp mechanism 26 includes a pair of left and right clamp units 32 and 34 for supporting and clamping both end surfaces of the pipe member 24 so as to be rotatable about their own central axes.

Here, the left clamp unit 32 for clamping the left end surface of the pipe member 24 in the drawing has a left mounting post 36 that is erected while being fixed on the left end portion of the base 22, A clamping cylinder 38 mounted horizontally on the upper end of the left mounting post 36, and a piston rod which projects horizontally from the clamping cylinder 38 and is driven forward and backward by the clamping cylinder 38 in the horizontal direction. 40 and a left clamp member 42 attached to the protruding end of the piston rod 40. The clamping cylinder 38 is connected to an air pressure source (not shown) via a three-way switching valve (not shown), and the three-way switching valve is connected to a control unit (to be described later) so that the driving state of the clamping cylinder 38 can be improved. Is controlled to be switched. That is, this three-way switching valve has a first port for releasing compressed air from an air pressure source to the atmosphere, a second port for introducing the piston rod 40 into the clamping cylinder 38 so as to drive the piston rod 40, and a piston port. The rod 40 is configured to be switched and driven based on a control signal from the control unit between the rod 40 and a third port which is introduced into the clamping cylinder 38 so as to be driven.

In this embodiment, the left clamp member 42 is configured so as to be able to clamp the outer circumference of the left end portion of the pipe member 24 on which the female screw 18 is screwed. The left clamp member 42 is formed in accordance with the outer diameter of the pipe member 24 to be clamped. When using pipe members 24 having different outer diameters, the left clamp member 42 is formed in accordance with the outer diameter. The clamp member 42 must be replaced, and therefore the left clamp member 42 is detachably attached to the piston rod 40. Further, the piston rod 40, to which the left clamp member 42 for clamping the pipe material 24 is attached, allows the pipe material 24 to be rotationally driven by the pivoting mechanism 28, which will be described later. It is rotatably supported around its own central axis.

In addition, the rotation axis formed by the center axis of the mounting rod 46 (that is, the rotation center of the right clamp member 48) is aligned with the rotation center of the left clamp member 42 described above, that is, located on the same horizontal axis. Is set to.

In this embodiment, the right clamp member 48 is configured to be able to clamp the inner circumference of the right end portion of the pipe member 24 on which the male screw 20 is threaded. The right clamp member 48 is formed in accordance with the inner diameters of the pipe members 24 to be clamped, and when the pipe members 24 having different inner diameters are used, the right clamp member 48 formed in accordance with the inner diameters is used. Therefore, the right clamp member 48 is detachably attached to the attachment rod 46. A driven pulley 50, which constitutes a turning mechanism 28 described later, is coaxially fixed to the outward protruding end of the mounting rod 46.

As described above, the clamp mechanism 26 is configured to include the pair of left and right clamp units 32 and 34. Therefore, in a state in which both are separated by a distance longer than the entire length of the pipe material 24 to be clamped, By interposing the pipe member 24 between them and activating the clamping cylinder 38, the left clamp member 42 is projected toward the right clamp member 48. In this way, the pipe member 24 is a pair of left and right clamp members. It will be clamped (sandwiched) by the members 42 and 48. As is clear from the above description, the pipe material 24 is held in a state of being clamped between the clamp members 42 and 48, and is brought into a state of being rotatable about its own central axis.

Next, with reference to FIGS. 7 and 8, a rotating mechanism 28 for rotationally driving the pipe member 24 clamped by the above-described clamp mechanism 26 will be described in detail. The rotation mechanism 28 includes the driven sprocket 50, the rotation driving motor 52 attached to the right side portion of the base 22, the reduction gear mechanism 54 connected to the motor 52, and the reduction mechanism 54. A drive sprocket 56 attached to the output shaft, an endless chain 58 wound around the drive sprocket 56 and the driven sprocket 50, and a detection unit 60 for determining the rotation stop position of the right clamp member 48. It is configured with.

The detection unit 60 includes a detection disc 60a coaxially and integrally attached to the outer protruding end of the attachment rod 46 described above, and the strainer 12 described above on the outer surface of the detection disc 60a. The number of cut grooves 16 corresponds to the number of the cut grooves 16 in the circumferential direction, that is, in this embodiment, the number of cut grooves 16 arranged in a total of 8 rows is set at every 45 degrees. It comprises eight detection dogs 60b arranged at equal intervals along the direction, and an indexing sensor 60d mounted on the right mounting post 44 via a mounting stay 60c. In this embodiment, the indexing sensor 60d is composed of a proximity sensor, and is set to be turned on each time each detection dog 60b comes closest.

As shown in FIG. 8, the indexing sensor 60d is connected to a control unit 62 that controls the entire strainer processing machine 10, and the control unit 62 is connected to a motor driver 64 of the motor 52. It is connected. Then, this control unit 62 outputs a drive stop signal for stopping the drive of the motor 52 to the motor driver 64 every time the ON signal from the index sensor 60d is input, and the cut mechanism 30 described later outputs the drive stop signal. Each time a cut end signal indicating that the cutting operation for one row along the axial direction (that is, the operation of forming the cut groove 16 over the entire length in the axial direction for one row) is completed is input to the motor driver 64. It is configured to output a drive start signal for starting the drive of the motor 52.

Since the rotating mechanism 28 is configured in this manner, every time the cutting mechanism 30 completes the cutting operation for one row along the axial direction, the indexing angle (( In this embodiment, the pipe member 24 is driven to rotate about its own central axis by "45 degrees". The control unit 62 described above cuts the pipe material 24 all around when the ON signal is output from the indexing sensor 60d by the number corresponding to the total number of times of the indexing (in this embodiment, “8 times”). It is set to output a processing operation end signal indicating the end of the processing operation of one pipe material 24 when the operation is completed.

Next, with reference to FIG. 9 and FIG. 10, a detailed description will be given of the cutting mechanism 30 for cutting the pipe material 24 clamped by the above-mentioned clamping mechanism 26 to form a large number of cut grooves 16. To do.

The cutting mechanism 30 includes a movable table 66 arranged on the base 22 so as to be movable along the extending direction of the central axis of the pipe material 24 clamped by the clamping mechanism 26, and the movable table 66. A guide mechanism 68 that movably guides the moving table 66 along the extending direction of the central axis of the pipe material 24 clamped by the clamp mechanism 26, a drive mechanism 70 that drives the moving table 66 to move, and a moving table 66. Depending on the movement of the cutter unit 72 and the cutter unit 72 for forming the cut groove 16 in the pipe member 24 disposed above and clamped by the clamp mechanism 26 along the axial direction of the pipe member 24, In order to always support the bottom portion of the pipe material 24 to be cut by this, it is provided with a supporting mechanism 74 similarly arranged on the moving table 66. .

Here, the above-mentioned guide mechanism 68 is attached / fixed to the opposite side in FIG. 9 (that is, the left side in FIG. 10) on the above-mentioned base 22 and the pipe member 24 clamped by the clamp mechanism 26. The guide rod 76 extending along the direction of extension of the central axis of the is fixedly attached to the lower side of the lower surface of the moving table 66 in the figure, fitted into the guide rod 76, and guided along the same. The guide bush 78 and the base 22 are attached / fixed to the front side in FIG. 9 (that is, the right side in FIG. 10) and along the extending direction of the central axis of the pipe material 24 clamped by the clamp mechanism 26. The guide rail 80 extends and a guide roller 82 rotatably mounted on the guide rail 80 on the lower side of the lower surface of the moving table 66 in the figure. There is.

Since the guide mechanism 68 is configured as described above, the moving table 66 is guided so as to be reciprocally movable along the extending direction of the central axis of the pipe material 24 clamped by the clamp mechanism 26. become.

Further, a drive mechanism 70 for moving and moving the moving table 66 along the extending direction of the central axis of the pipe material 24 clamped by the clamp mechanism 26 is arranged in the base 22, as shown in FIG. A drive motor 84 provided, a drive sprocket 86a coaxially mounted and fixed to the motor shaft of the drive motor 84, and a pair of idle sprockets 86b, 86c respectively attached to the left and right ends of the base 22 while rotating independently. , A pair of idle sprockets 86d 1 and 86e 2 which are closely spaced to each other at a substantially central portion of the lower surface of the top plate of the base 22 and are arranged at the center position of the base 22 below both idle sprockets 86d 1 and 86e 2. And a small diameter driven sprocket 86f, a large diameter connecting sprocket 86g coaxially fixed to the driven sprocket 86f, and a movable table at one end. The left idler sprocket 86b, the center left idler sprocket 86d, the driven sprocket 86f, the center right idler sprocket 86e, and the right end idler sprocket 86c, which are successively connected to the left idler sprocket 86b. , A transmission chain 88 connected to the right side of the moving table 66, and an endless chain 90 hung between a drive sprocket 86a and a connecting sprocket 86g.

Since the drive mechanism 70 is configured as described above, the moving table 66 is clamped by the clamp mechanism 26 via the endless chain 90 and the transmission chain 88 when the drive motor 84 is activated. It is moved and driven along the extending direction of the central axis of the material 24. Although not shown, end sensors are arranged opposite to each other at both ends of the guide rod 76 of the guide mechanism 68 described above, and these end sensors are connected to the control unit 62 described above. Further, the control unit 62 is connected to a motor driver (not shown) of the drive motor 84. The control unit 62 is configured to output a drive reversal signal for reversing the drive direction of the drive motor 84 to the motor driver each time the detection signal from each end sensor is input. There is.

A cutter unit 72 for forming the cut groove 16 in the pipe material 24 clamped by the clamp mechanism 26 along the axial direction of the pipe material 24 is provided on the moving table 66 as shown in FIG. A mounting post 92 fixed in an upright position, a swinging arm 94 having a central portion at the upper end of the mounting post 92, and a swinging arm 94 swingably supported around an axis orthogonal to the above-described moving direction, The cutter motor 96 attached to the inner end of the swing arm 94 (that is, the end on the side where the pipe member 24 is disposed) and the cutter that is rotationally driven around the axis orthogonal to the moving direction described above. A disc-shaped cutter blade 98, which is detachably attached to the motor shaft of the motor 96 and is rotationally driven by the cutter motor 96, and an outer end portion of the swing arm 94 (that is, the pipe member 24 is An oscillating drive unit for oscillating the oscillating arm 94 in a state where the vertical distance between the end on the side opposite to the disposed side) and the lower end of the mounting post 92 can be adjusted. And 100.

Here, the swing drive unit 100 includes a fixed block 102 attached to the lower end of the attachment post 92, and an adjusting screw rod 104 connected to the fixed block 102 so as to be vertically movable. A notch cylinder 106 is attached to the tip of the adjusting screw rod 104 in a swingable and substantially vertical state, and a notch cylinder 106 is driven to move back and forth from the tip of the notch cylinder 106 in a substantially vertical direction. The above-described swing arm 94 is provided with a piston rod 108 pivotally supported at the outer end of the swing arm 94.

Here, the adjusting screw rod 104 is inserted into the fixing block 102, and the vertically projecting end portions from this are tightened from above and below by the pair of upper and lower fixing nuts 110 and 112, whereby the fixing block 102 is fixed. It is designed to be attached to 102 in a state in which vertical movement is prohibited. The cutting cylinder 106 is connected to the above-mentioned pneumatic source (not shown) via a three-way switching valve (not shown), and the three-way switching valve is connected to the control unit 62 described above. The drive state of the slip-in cylinder 106 is switched and controlled. That is, this three-way switching valve has a first port for releasing compressed air from an air pressure source to the atmosphere, and a second port for introducing the piston rod 108 into the slitting cylinder 106 so as to drive the piston rod 108. The piston rod 108 is configured to be switched and driven based on a control signal from the control unit 62 between the piston rod 108 and a third port which is introduced into the slitting cylinder 106 so as to drive the piston rod 108.

Further, in the swing drive unit 100, the cutting blade 98 connected to the cutting cylinder 106 pulls and drives the piston rod 108, and the cutting blade 98 connected to the cutting cylinder 106 pulls the piston rod 108. When the piston rod 108 is driven to project, the cutting blade 98 connected to the piston rod 108 is held at a standby position separated from the outer periphery of the pipe member 24 by the outer periphery of the pipe member 24 clamped by the clamp mechanism 26. It is set so that they come into contact with each other and are brought to a processing position where they are cut.

Since the swing drive unit 100 is configured in this manner, the cutting cylinder 106 pulls the piston rod 108 in a state other than when the pipe material 24 is supported by the clamp mechanism 26 and processed. The cutter blade 98 is driven to hold the cutter blade 98 in the standby position, and only when a machining signal is output from the control unit 62, the cutting cylinder 106 drives the piston rod 108 to project so that the cutting blade 98 is moved from the standby position. The pipe material 24 is swing-driven to the processing position, and the processing operation of the pipe material 24, that is, the operation of forming the cut groove 16 is executed.

In such a processing operation, the outer diameter of the pipe material 24 to be processed is, for example, as shown in FIG. 9, from the pipe material 24 shown by the solid line to the pipe material 24 shown by the chain double-dashed line. ′, As described above, the clamp members 42, 48 of the left and right clamp units 32, 34 of the clamp mechanism 26 are replaced and changed according to the outer diameter of the pipe material 24 ′. Also in the cutting mechanism 30, by loosening the pair of upper and lower fixing nuts 110 and 112, the adjusting screw rod 104 is appropriately moved in the vertical direction with respect to the fixing block 102, and the cutting length of the cutter blade 98 is increased. The optimum swing position for setting the height, that is, the standby position separated by a predetermined distance from the outer periphery of the pipe material 24 'having a predetermined outer diameter, is swung to the optimum position. The position of the adjusting screw rod 104 with respect to the fixed block 102 is fixed by tightening both fixing nuts 110 and 112 so as to achieve the cut length. In this manner, the vertical position of the cutting cylinder 106 is adjusted so that a desired cutting length can be obtained by the cutter blade 98 with respect to the pipe material 24 (24 ') having any outer diameter. You will be able to adjust.

Next, according to the movement of the cutter unit 72, a supporting mechanism 74 similarly arranged on the moving table 66 for constantly supporting the bottom portion of the pipe material 24 cut by the cutter unit 72 is shown in FIG. This will be described with reference to FIGS.

The support mechanism 74 includes a pair of support posts 114a and 114b that are planted on the moving table 66, and a pipe guide roll that is rotatably supported while being suspended between the support posts 114a and 114b. 116 can be said. The support posts 114a and 114b are arranged so as to be located on both sides in the radial direction of the pipe member 24 supported by the clamp mechanism 26 with the central axis line therebetween. The pipe guide roll 116 has a so-called drum-shaped roll main body 116a having a central portion to receive the outer circumference of the supporting pipe member 24 complementarily, and both end surfaces of the roll main body 116a coaxially with the roll main body 116a. The shaft portions 116b projecting outward from the shaft portions 116b and the bearings 116c fitted in the respective shaft portions 116b. A recess 118 is formed on the upper surface of each of the support posts 114a and 114b to receive the bearing 116c fitted to the corresponding shaft portion 116b from above.

As is apparent from FIG. 9, the rotation axis of the cutting blade 98 is set to be located in the same vertical plane as the rotation axis of the pipe guide roll 116. Since the support mechanism 74 is configured in this manner, the outer periphery of the pipe member 24 is received in line contact with the constricted outer periphery of the roll body 116a of the pipe guide roll 116, and the support state is ensured and reliably. It can be stable. In addition, even when the pipe member 24 is rotationally driven around its own central axis by the above-described rotating mechanism 28, the outer periphery of the pipe member 24 is complementarily received by the outer periphery of the roll body 116a, and therefore, The pipe member 24 continues to be slidably supported in the state where the line contact state is maintained, and thus the pivotal state of the pipe member 24 is also favorably supported. Furthermore, since the pipe guide roller 116 is rotatably supported by the bearing 116c about its own central axis, the pipe material 24 is itself supported by the clamping cylinder 38 of the clamping mechanism 26 described above. Even when the pipe material 24 is moved along the central axis of the pipe material 24, the pipe material 24 continues to be rotatably supported while maintaining the above-mentioned line contact state. The condition will be well supported.

As is clear from the above description, since the pipe guide roll 116 is attached to the pair of support posts 114a and 114b in a state of being fitted from above, the pipe guide roll 116 will be described in detail. Since the pair of bearings 116c are inserted into the recesses 118 formed in the corresponding support posts 114a and 114b from above, the bending ratios of the outer circumference of the pipe member 24 to be supported are as shown in FIG. Accordingly, when replacing the pipe guide roll 116 shown by the solid line with the pipe guide roll 116 'shown by the chain double-dashed line, the pipe guide roll 116 is simply pulled up and removed from the pair of support posts 114a, 114b. Install a new pipe guide roll 116 'onto the pair of support posts 114a and 114b from above. By mating, you can easily replace it.

Using the strainer processing machine 10 configured as described above, a processing operation for forming the strainer 12 by processing the pipe material 24 in which the female screw 18 and the male screw 20 are respectively threaded at both left and right ends. Will be described as a control procedure of the control unit 62.

First, when the machining operation is activated, the control unit 62 performs switching control so that the three-way switching valve of the clamping cylinder 38 in the clamping mechanism 26 communicates with the second port, and the corresponding piston rod. 40 is retracted and driven, the rotation drive motor 52 in the rotation mechanism 28 is activated, and the right clamp member 48 is rotationally driven until the index sensor 60d detects the predetermined detection dog 60b, and the cutting mechanism 30 is driven. The three-way switching valve of the notifying cylinder 106 is controlled so as to communicate with the second port, and the corresponding piston rod 108 is retracted and driven, and the drive motor 84 of the drive mechanism 70 in this cutting mechanism 30 is driven. It starts up and moves the moving table 66 until the left end sensor (not shown) is turned on. In this manner, the pipe member 24 is set to the initial state in which the clamp member 26 can be clamped.

From this initial state, the pipe member 24 is interposed between the pair of left and right clamp members 42 and 48 of the clamp mechanism 26, and the operator presses a clamp button (not shown), so that the control unit 62 The three-way switching valve of the clamp cylinder 38 is controlled so as to communicate with the third port, and the corresponding piston rod 40 is pushed out to drive the pipe member 24 between the clamp members 42 and 48 in this manner. Will be clamped.

After that, the operator confirms that the pipe material 24 is clamped well, and then presses a cut button (not shown). In response to this, the control unit 62 starts the machining operation. That is, first, the cutter motor 96 is activated to start the rotational driving of the cutter blade 98. Then, the drive motor 84 of the drive mechanism 70 is started to move and drive the moving table 66, and the cutter blade 98 is moved to just above the predetermined cutting position. After that, the three-way valve of the notch cylinder 106 is switched and controlled so as to communicate with the third port, the cutter blade 98 is driven to swing downward, and the outer periphery of the pipe member 24 clamped by the clamp mechanism 26 is A notch groove 16 extending along the central axis of this is formed at the left end of the pipe member 24 in a state of penetrating in the thickness direction.

Here, when the axial length of the cut groove 16 thus formed reaches the required length, the control unit 62 sets the three-way switching valve of the cut cylinder 106 to the second port. Switching drive is performed so as to communicate with each other, and the corresponding piston rod 108 is retracted and driven to raise the cutter blade 98. When the cut length of the cut groove 16 formed by the cutter blade 98 is longer than the diameter of the cutter blade 98, the control unit 62 activates the drive motor 84 of the drive mechanism 70 to cause the cut groove. The cutter unit 72 is driven to move rightward in the drawing until the axial length of 16 reaches a desired cut length.

When the operation of forming one cut groove 16 is completed in this way and the cutter blade 98 is moved up to the standby position, the control unit 62 activates the drive motor 84 of the drive mechanism 70 to move the shaft. The cutter unit 72 is driven to move rightward in the drawing along the direction to the position where the next adjacent cut groove 16 is formed. Then, the forming operation of the cut groove 16 described above is executed. Such a forming operation of the cut groove 16 is continued until the forming operation over the entire axial length thereof is completed.

After the operation of forming the cut groove 16 located at the right end of the pipe material 24 is completed, when the cutter unit 72 is further moved to the right in the drawing, the right end sensor (not shown) faces here. It will be turned on by the provided transfer table 66. The control unit 62 reverses the drive direction of the drive motor 84 of the drive mechanism 70 in response to the input of the ON signal from the right end sensor, and causes the rotation drive motor 52 of the rotation mechanism 28 to move to the next sensor 60d. The detection dog 60b is rotationally driven until it is detected.

As a result, the cutter blade 98 is positioned on the formation line of the next cut groove 16 set laterally in the circumferential direction, and is driven back to the left side of the pipe material 24 in the drawing. Become. The return drive is continued until the left end sensor (not shown) is turned on by the moving table 66 facing the left end sensor, and at this time, the drive direction of the drive motor 84 of the drive mechanism 70 is reversed again. The cutter unit 72 is moved until it is brought to the leftmost formation position on the formation line. In this way, the forming operation of the cut groove 16 on the forming line is executed.

After that, every time the forming operation of the cut groove 16 on the forming line is completed, the rotating operation to the next forming line in the circumferential direction is executed together with the returning operation described above. As shown in FIG. 1, the operation of forming the cut groove 16 over the entire circumference and the entire length of the pipe material 24 is completed. When the control unit 62 detects the completion of the forming operation of all the cut grooves 16 in this way, the operator has completed the forming operation of all the cut grooves 16 in the pipe material 24 through an alarm device (not shown). Is notified, and the operator removes the pipe material 24 for which the forming operation of all the cut grooves 16 is completed, that is, the completed strainer 12 from the processing apparatus 10, thereby ending a series of processing operations.

As described above, by using the strainer processing apparatus 10 having the above-described configuration, the strainer 12 is automatically processed / formed by simply setting the pipe material 24 in the strainer processing apparatus 10. Therefore, the workability is extremely improved.

Needless to say, the present invention is not limited to the configuration of the above-described embodiment and can be variously modified without departing from the gist of the present invention.

For example, in the above-described embodiment, the clamp cylinder 38 and the notch cylinder 106 are both pneumatically driven, but the present invention is not limited to this configuration. Instead, it may be hydraulically driven, and it is also possible to use other moving drive means, such as a drive motor, instead of the cylinder.

Further, in the above-mentioned one embodiment, it is explained that it is applied to form the strainer 12 having the shape shown in FIGS. 1 to 3, but the present invention is limited to such an application mode. Without being performed, the application mode is not limited as long as a large number of cut grooves are formed on the outer periphery of the pipe material in a state of penetrating in the thickness direction.

Further, in the above-described embodiment, the description has been made such that the cut grooves are formed in eight rows in the circumferential direction, but the present invention is not limited to such a configuration and is shown in the embodiment. Numerical values are merely examples and do not limit the invention in any way.

Further, in the above-described embodiment, the description has been made such that the female screw 18 and the male screw 20 are preliminarily threaded at both ends of the pipe member 24, but the present invention has a pipe member formed in this way. It is needless to say that the present invention is not limited to processing 24, and can be applied to processing, for example, a pipe material 24 in which female threads and male threads are not formed at both ends.
