CONSTITUTION:A mandrel 3 attached freely rotatably to a support base 2A in a spinning machine 1 is disposed to face to a pressing device 5 via a thin sheet 4 of a metallic material. An X-axis screw bar 9 is inserted between a screwed bearing 7A of a support base 7 for an X-axis section and a screwed bearing 7B attached to a body 2A of a lathe bed. If an X-axis motor 10 coupling to the end of the bar 9 runs forward and reverse, the base 7 moves back and forth along the bar 9. A Y-axis screw bar 11 is supported by the base 7 and its front end is extended between the mandrel 3 and the device 5. A Y-axis motor 12 is coupled to the end of the bar 11 and is supported on the side face of the base 7. If the motor 12 is run forward and backward, the bar 11 rotates in the same direction and therefore a roll support base 8 for the Y-axis section moves back and forth along the bar 11 and the roll 13 fixed to the base 8 presses the sheet 4.

Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention compresses and supports a thin plate between a mandrel and a pressing device, and presses the thin plate against the mandrel with a roller to form a metal container having an opening at one end. Concerning improvement of a deformation processing machine for forming.

[Prior art]

In general, deforming machines, such as spinning machines, are suitable for producing large diameter, thick-walled metal tubes, which are not mass-produced products. A spinning machine presses and supports a thin metal plate having an overhang larger than the diameter of the mandrel between a mandrel and a pressing device, such as a hydraulic device. By pressing the protrusion against the mandrel many times with the roller in contact with the protrusion, a metal container having an opening at one end and a bottom at the other end can be formed. By cutting the bottom side of the metal container, a hollow metal tube can be formed. In a spinning machine, the number of metal tubes that are formed depends on the amount of pressure applied by the operator to the protruding portion with a roller, the timing of the pressing speed, etc.
Dimensions, deformation, etc. are slightly different. Producing multiple metal tubes with the same size and shape as possible requires a high degree of skill from the operator, and pressing the protruding parts with rollers requires great physical strength and skill. So the spinning work was not easy.

[Purpose of the invention]

An object of the present invention is to provide a deforming machine that facilitates spinning operations.

[Summary of the invention]

In order to achieve this objective, the present invention rotates an operating lever that operates a roller that presses a workpiece, and an X-axis rotary encoder and a Y-axis rotary encoder according to the operation locus of the operating lever. The object of the present invention is to deform a workpiece by controlling the driving time and rotation direction of an X-axis drive means and a Y-axis drive means using electric signals.

makes a reciprocating motion along the X-axis threaded rod 9. Y-axis threaded rod 1
1 is supported by the X-axis support stand 7. The tip is mandrel 3
and the pressing device 5. Y-axis? A threaded bearing (not shown) inserted into the rod 11 is attached to the X-axis support stand 8.
It is connected with. The Y-axis motor is connected to the end of the Y-axis threaded rod and supported on the side surface of the X-axis roller support stand. Y
When the axis motor 12 is rotated in the forward and reverse directions, the Y-axis threaded rod 11 also rotates in the same direction, so the X-axis roller support base 8 reciprocates along the Y-axis threaded rod 11. The roller 13 fixed to the X-axis roller support 8 presses the thin plate 4.

One end of the control circuit 14 is connected to the X-axis motor 10 and the Y-axis motor 12 via a control line 15. The other end is connected to a memory circuit 18, such as a floppy desk and an operation panel 20, via control lines 16, 17e.

The operation panel 20 has two Y-axis seals 2 corresponding to each other on the top surface.
Install 1A and 21B, and Y-axis seal 21A.

21B is engaged with the base groove 22. base 23
A base groove portion 22 is attached to the lower surface side, and an X-axis seal 24 extending between Y-axis seals 21A and 21B is attached to the upper surface. The guide 25 has a guide groove 26 on the lower side that engages with the X-axis seal 24, and an operating lever 27 on the upper side.
is installed.

The operation lever 27 moves in the same manner as the operation lever of a drafter for drafting. An X-axis grooved belt 30 and an X-axis grooved belt 31 are attached between the base 23 and guide 25 and the contact plate 28, 29.

Y III + belt 30 is one Y axis seal 21B
It is arranged correspondingly. xH belt 31 is X axis seal 31
One end of the X-axis belt 31 has an X-axis rotating roller 32, and the other end has an X-axis rotary encoder 33. The X-axis belt 31 rotates in the normal direction when moving the base 25 from the right side to the left side. The Y-axis belt 30 is Y
A Y-axis rotary roller 34 is attached to one end of the Y-axis belt 30, and a Y-axis rotary encoder 35 is attached to the other end of the Y-axis belt 30, which is arranged corresponding to the shaft seal 21B. The Y-axis belt 30 rotates in the normal direction when moving the base 23 from the bottom to the top. When the Y-axis belt 30 and the X1ll belt 31 rotate in the forward direction, the X-axis rotor IJ-xy gouda 33 and the Y-axis rotary encoder 35 rotate in the forward direction to generate an addition system pulse signal. In the opposite case, a subtraction pulse signal is generated. Brush, X-axis rotary encoder 33 and Y-axis rotary encoder 35u
, X-axis belt 31 and Y-axis bell) 30 are converted into pulse signals or electrical signals. The pulse signal or electrical signal is stored in the storage circuit 18 via the control lines 16, 17 and the control circuit 14.

Next, the operating lever 27 moves along the operating trajectory 5l shown in FIG. 2A.
When the operation is performed to draw IS2*SB, the roller 13 presses the thin plate 4 as shown in FIG. 2B according to the first operation trajectory SI, and the thin plate deforms 4S as shown in FIG. 2C.
form l. Further, according to the operation trajectory 82.8s, the roller 13 presses the thin plate 4, causing the thin plate to deform 48. Then, through thin plate deformation 4S3, a metal container 40 having an opening at one end is formed.

FIG. 3A showing the details of the operating locus of the operating lever 27 that forms the metal container 40 in this way is shown in FIGS. 3B to 3C.
As shown in the figure, it is converted into a pulse signal, and the
The X-axis motor 10 and the X-axis motor 12 shown in the figure are rotated in forward and reverse directions. 3B and 3C show the pulse time on the Y-axis and the Y-axis.1. When the arrow direction progresses from left to right, the addition time is increased, and when the arrow direction advances from right to left, the addition time is
The subtraction time is shown respectively. That is, 0) When the operation locus position is 0 When the operation lever 27 is at the origin 0 in FIG. 3A, the X-axis rotary encoder 33 and the Yl'lfl rotary encoder 35 are not rotating, so the X-axis system in FIG. 3B The pulse signal, the X-axis pulse signal in FIG. 3C, is not generated. Therefore, the X-axis motor 10 and the X-axis motor 12 do not rotate, and the roller 13 operates at a position apart from the thin plate 4 shown in FIG. 3B.

1) When the operation lever 27 moves from the 0 position to the A position in Fig. 3A during operation trajectory ■, the Y axis changes from 0 to XA, and the Y axis changes from O to YA.
, they each move in the same direction, that is, in the addition direction. Therefore, the X-axis rotary encoder 33 and the Y-axis rotary encoder 35 rotate forward the same number of times, and the pulse signals [phase] and [phase] shown in FIGS. 3B and 3C are controlled by the control circuit shown in FIG. 1. 14, is input to the memory circuit 18. The output from the control circuit 14 is the X-axis motor 1o and the X-axis motor 1.
2 is input. X-axis motor 10% Y111 units 7, Y
The shaft system support stand 8 is moved in the direction of the thin plate. As a result, the roller 13 presses the thin plate 4 at the position A where it contacts the thin plate 4 in FIG. 2B.

2) When operating locus ① When the operating lever 27 moves from position A to position 81 in FIG. 3A, the Y-axis moves from XA to XS1 in the addition direction. On the other hand, the Y-axis is in the subtraction direction moving from YA to -Y81.

Therefore, the X-axis rotary encoder 33 rotates forward,
The Y-axis rotary encoder 35 rotates in the opposite direction, and the pulse signals (c) and pulse signals (c) shown in FIGS. 3B and 3C are generated, respectively.
, [phase] are input to the control circuit 14 and storage circuit 18 in FIG. As a result, the X-axis motor 10 continues to rotate in the forward direction.
Since the X-axis motor 12 rotates in the opposite direction, the roller 13
Move from position to S1 position and perform thin plate deformation 4S in Fig. 3C.
form 1.

3) At the time of operation trajectory ■, the operation lever 27 moves from position 81 in FIG. 3A to position B. On the Y-axis, the direction is subtraction even after returning from XS1 to XAI. Since the X-axis rotary encoder 33 rotates in the opposite direction, a pulse signal Q is obtained. On the other hand, since the Y-axis does not move, it is at the same position as in 3) above, so the response signal at this time is Q→.As a result, only the X-axis motor 10 rotates in the reverse direction, and the roller 13 moves to S1. It moves from the position to the B position and leaves the thin plate deformation 4S1.

4) When operation trajectory ■ The operating lever 27 moves from B to At in FIG. 3A.

On the Y axis, it has moved from -YS1 to YAI,
This is the direction of addition. Since the Y-axis rotary encoder 35 rotates in the forward direction, it generates the pulse signal q seconds shown in FIG. 3C. On the other hand, since the Y-axis has not moved, XAI is at the same position as in 3) above. The pulse signal at this time is C~. As a result, the X-axis motor 12 rotates forward, and the roller 13 moves to the A1 position in FIGS. 3B and 3C. Tsumashi,
Contact is made inside the thin plate deformation 481.

5) After that, the operation trajectory S2 in FIG. 3A. S3 is repeated to obtain the A) response signal in FIGS. 3B and 3C, and the roller 13 deforms the thin plate 482 and 483 (FIG. 2C) to form the metal container 40, but the thin plate deforms. As the deformation process progresses, as the amount of deformation υ decreases, the operating locus 82°83 also becomes smaller, as shown in FIG. 2A.

As described above, in the present invention, the operation time and rotation direction of the X-axis motor 10 and the Y-axis heater 35 can be controlled by operating the operation lever ζ-27. Does not require physical strength. Further, the operating locus of the operating lever 27 (FIG. 3A) is stored in the memory circuit 18 with the pulse signal times shown in FIGS. 3B and 3C. In this case, the manufacturing of the metal container 40 from the second time onward can be performed automatically since the X-axis motor 10 and the X-axis motor 12 can be fully automatically controlled by the pulse signal from the memory circuit 18. I can do it. Therefore, all metal containers 40 can be manufactured to have a uniform shape.

In the embodiments described above, X-axis and Y-axis motors were used, but hydraulic cylinders may also be used.

In the case of a hydraulic cylinder, electric signals generated by the Y-axis and the Y-axis rotary encoder control the time for oil to enter and exit the hydraulic cylinder, and the X-axis system is supported in accordance with the expansion and contraction of the piston, which is the guide means. Move the stand and Y-axis support stand.

〔Effect of the invention〕

As described above, according to the present invention, spinning work can be easily performed.
