, the movable tool rest 36 rises while being guided by the guide rod 38 and guide member 391 while resisting the spring 41, and the movable blade 37 and fixed blade 35 cut the material 9 to a certain size. do.

The material 57 that has been cut to a fixed size is placed on the cutting table 55.

In this way, the fixed-size cutting device 1 intermittently feeds the material 9 by a fixed size to the cutting device 11 using the intermittent feeding device 10, and then sequentially cuts the material 9 by the cutting device 11. The cutting length can be arbitrarily adjusted according to the diameter of the damper to be manufactured by changing the connecting position of the connecting rod 22 with respect to the feed adjustment lever 21.

(9) Rotary table 2 The rotary table 2 holds the material 57 cut to a fixed size,
It is for sequentially transferring from the supply position H shown in FIG. 1 to the bottom press position 1, the punching press position J, and the outer diameter punched piece take-out position while rotating intermittently in the direction of the arrow d. ,
It is equipped with eight material processing holes 60 drilled at equal intervals in the circumferential direction, and a material holding mechanism 61 provided to be openable and closable corresponding to each company 60, and is constructed as follows. ing.

That is, as shown in FIGS. 12 and 13, the rotary table 2 is fixed to a mounting plate 634 at the upper end of the vertical shaft 62.
2 is rotatably supported by a mounting frame 64 mounted on the machine frame 8 via a bearing 65, and is also provided with a table rotation operation mechanism 66 and a table reversal prevention mechanism 67.

The table rotation operation mechanism 66 includes a brake drum 68 fixed to the lower end of the vertical shaft 62 similarly to the anti-reverse brake 26.
A pair of brake shoes 69 that sandwich the brake drum 68, a brake arm 70 that supports one end of the brake shoes 69, a bolt 71 inserted into the other end of the brake shoe 69, and a screw threaded into the bolt 71. This is a brake structure including a spring 73 interposed between a nut 72 and a brake shoe 69 that are fitted together, and the free end side of the brake arm 70 (this is the side of the drive system 7 described in detail in section 2). A connecting rod 95 is connected by a pivot pin 72,
The connecting rod 95 reciprocates in the axial direction.

As shown in FIG. 14, the table reversal prevention mechanism 67 consists of a roller 75 rotatably supported by a support shaft 74 on the lower side of the mounting plate 63 (corresponding to each company 60), and a fixed plate at the upper end of the mounting frame 64. 76 is provided with a blocking pawl 78 rotatably attached to the fixing plate 76 by a mounting bolt 77. The rotary table 2 is urged to engage with the roller 75 by a spring 80, so that the rotary table 2 can freely rotate in the direction indicated by the arrow d. They are engaged and cannot rotate.

The material holding mechanism 61 is supported by a mounting base 81 fixed on the rotary table 2 inside each company 60 and a pivot pin 82 that projects outward from the mounting base 81 so as to be vertically swingable. A pair of presser arms 83, a pair of presser claws 85 each attached to the tip end of each presser arm 83 with a bolt 84 so as to be able to freely adjust the angle, and a rod support supported near the base between both presser arms 83. 86, and a pushed up rod 87 pivotally supported by the rod support base 86,
The pushed-up rod 87 is suspended downward from a rod hole 88 formed in the rotary table 2.

On the other hand, between the supply position H and the outer diameter punched piece take-out position,
A push-up device 89 is provided to open and close each material holding mechanism 61 corresponding to both positions H and K.
An elevating plate 92 is vertically slidably supported by the guide rod 91, and at both ends of the elevating plate 92, positions H,
It is composed of a pair of push-up rods 93 that correspond to the push-up rods 87 of each material holding mechanism 61 in K and are provided so as to be able to adjust their relative heights. The push-up rod 94 moves up and down.

In the above configuration, the rotary table 2 is intermittently rotated by 1/8 in the direction of the arrow d in FIG. 13 by the reciprocating movement of the connecting rod 95.
It rotates.

That is, when the connecting rod 95 moves in the direction of arrow e, the brake arm 70 of the table rotation operation mechanism 66 rotates in the direction of arrow d, and the brake shoe 69 and brake drum 68
The vertical shaft 62 and the rotary table 2 rotate 1/8 in the same direction due to the frictional force between them.

At this time, the blocking claw 78 of the table reversal blocking mechanism 67 is urged toward the roller 15 by the spring 80, but the vertical shaft 6
2 and rotary table 2 start rotating in the direction of arrow d,
The roller 7 next to the roller 75 with which the blocking claw 78 was engaged
5 in the direction indicated by the arrow f around the mounting bolt 77 while resisting the spring 80, the rotation of the vertical shaft 62 and the rotary table 2 is not affected in any way.

Then, the rotary table 2 rotates 1/8, and the connecting rod 95
When the spring 80 (thus, the blocking pawl 78) engages with the roller 75, the rotary table 2 becomes unable to rotate in the direction of the arrow d, so that the brake drum 68 and A slippage occurs between the brake arm 70 and the brake shoe 69, and the brake arm 70 is forcibly pushed back in the direction opposite to the arrow d, thereby completing one intermittent rotation operation of the rotary table 2.

The rotary table 2 is thus intermittently rotated in the direction of the arrow d by the reciprocating movement of the O-shaped connecting rod 95, and the respective material holding mechanisms 61 are moved to the supply position H1, the forming press position 2, and the punching press position J1, the outer diameter punching piece. They are made to correspond sequentially to the take-out position, etc.

Then, the connecting rod 95 moves to the return movement and the rotary table 2
When the drive system 7 stops, the push-up rods 94 of the drive system 7 rise and push up the elevating plate 92 along the guide rod 91. The pressed upper rod 87 of the material presser mechanism 61 is pushed upward, and the presser arm 83, which has been in the closed state until now, is pushed upward.
is opened upward about the fulcrum pin 82, and the supply position H
Now, place the material 5 on the rotary table 2 so as to correspond to the hole 60.
7 is supplied, and at the outer diameter punched piece take-out position, the outer diameter punched piece is removed from the outside by compressed air injected from a compressed air injection nozzle 96 disposed outward from the center of the rotary table 2. When these steps are completed, the push-up rod 94 is lowered, the push-up device 89 is lowered, and the presser arms 83 at each position H are lowered, so that each of the claws 85 is placed on the rotary table 2. is held in contact with.

At this time, especially at the supply position H, the four presser claws 85
The supplied material 57 is pressed and held on the rotary table 2, and then the rotary table 2 is intermittently rotated in the direction indicated by the arrow d.

Material supply device 3 The material supply device 3 is for supplying the material 57 cut by the sizing cutting device 1 onto the rotary table 2, and as shown in FIGS. 11 and the rotary table 2, a pair of left and right side plates 97 installed on the machine frame 8, a parallel link mechanism 98 supported by each side plate 97, and a material 57 cut by the cutting device 11.
A material suction cup 99 that sucks the material and supplies it to the material holding mechanism 61 position on the rotary table 2 by the swinging movement of the parallel link mechanism 98 is provided. The material 57 is supplied between the two by a material suction cup 99.

There are a pair of parallel link mechanisms 98 on the left and right corresponding to each side plate 97, each of which has two swing links 100.1 (H), and the upper end of each swing link 100.1 (H) is a horizontal pivot. It is pivoted to the suction cup mounting base 104 by pins 102 and 103, and the lower end is attached to each side plate 9 by pivot pins 105 and 106.
At the same time as shown in FIG. Fixed for relative rotation.

The large diameter pinion gear 107 is connected to the side plate 9 via a bearing 109.
A drive lever 112 having a notched groove 111 on the free end side is fixedly attached to both ends of a horizontal main shaft 110 rotatably inserted into and supported by the main shaft 110, and a drive lever 112 having a notched groove 111 on the free end side is keyed to be integrally rotatable. The cutout groove 11 of this drive lever 112
1, the lifting rod 113 of the drive system 7, which will be described in detail in Section 3, is connected to the connecting pin 114,
3, the parallel link mechanism 98 can swing back and forth between the imaginary line position and the solid line position shown in FIG.

The material suction cup 99 is mounted on the suction cup mounting base 104, and the material suction cup 99 has a suction hole 1 that opens downward.
15, and is communicated with a vacuum pump (not shown) via a flexible suction pipe 116, and a solenoid valve 117 for material adsorption control is interposed in the flexible suction pipe 116.

In the above configuration, FIGS. 4 and 5 show the material suction cup 97.
shows a state in which the rotary table 2 is moved to the supply position H side.

When the intermittent feeding device 10 shifts to the feeding operation, the lifting rod 113 descends in approximately synchronization with this, and the drive lever 112 connected to it rotates in the direction of the arrow g in FIG. The large diameter pinion gear 107 rotates in the same direction by the same angle through the large diameter pinion gear 1.
The parallel link mechanism 98 is tilted toward the cutting device 11 through the small-diameter pinion gear 108 meshing with the pinion gear 107, and the material suction cup 99 is moved in parallel from the solid line position to the imaginary line position in FIG. Located in

When the material suction cup 99 moves to the top of the cutting table 55,
The solenoid valve 117 is switched by the control device number (not shown), and the suction hole 115 is communicated with the vacuum pump via the flexible suction pipe 116, so that the suction force σ at that time causes the cutting table 55 to
The upper material 57 is attracted to the material suction cup 99.

When the material suction cup 99 suctions the material 57 on the cutting table 55 in this way, the lifting rod 11
3 shifts to an upward movement, and the movement t is opposite to that described above.Thus, the parallel link mechanism 98! From this, the material suction cup 99 moves in parallel to the supply position H side of the rotating cable 2 and carries the material 57 onto the rotating cable 2. In this case, the material suction cup 99
is supported by the parallel link mechanism 98, so it moves in an arc shape while maintaining a parallel state, and its moving speed is the same as when it is located on the cutting table 55 and the rotary table 2, that is, immediately after starting the movement and immediately before stopping the movement. is slowest and fastest in the middle, so the material suction cup 99 can reliably suck the material 57 on the cutting table 55, and can prevent the material 57 from falling off the material suction cup 99 during movement.
Furthermore, when the material 57 is carried onto the rotary table 2, the relative position of the material 57 with respect to the hole 60 can be ensured, and the material 57 can be prevented from being largely displaced from the hole 60.

Since the lifting rod 113 moves synchronously with the push-up rod 94, when the material suction cup 99 moves onto the rotary table 2, the material holding mechanism 61 is pushed up by the push-up device 89 and is in the open state. After the solenoid valve 117 is switched and the material suction cup 99 releases the material 57, it starts returning to the cutting device 11 side, and at the same time [as described in detail in the previous section, the material holding mechanism in the supply position H] 61 is closed, and the presser claw 85 at the tip of the presser arm 83 presses the material 57 into the hole 60.
It is pressed and held on the rotary table 2 at a position corresponding to .

This completes the operation of supplying the material 57 to the rotary table 2, and then the rotary table 2 rotates intermittently by 1/8 rotation.
After cutting the material 57 to a fixed size according to step 1, the cut material 57 is sucked by a material suction cup 99 and supplied onto the rotary table 2. If the material 57 is cut into a fixed size according to the diameter of the damper to be manufactured, It is only necessary to cut the material 9 to length, and therefore, waste of the material 9 can be reduced and the yield can be greatly improved.

■ Forming press device 4 The forming press device 4 press-forms the material 57 held by the rotary table 2 and sent to the forming press position ■ into a predetermined damper shape, and is shown in Figs. 15 and 16. As shown in FIG. 2, there are a raised adjoining part 118 and a lower part adjoining part 119 arranged above and below with the rotary table 2 in between, and an upper bottom mold 120 attached to each of the elevating tables 118 and 119.
and an air cylinder 122 that raises and lowers the lower molding die 121 and the rising neighbor 118; and in conjunction with the raising and lowering movement of the rising neighbor 118, the lower molding die 121 moves before the upper bottom mold 120 when lowering. and a cam mechanism 123 that raises the lower boundary 119 to contact the material 57 and maintain the contact state.

An upper rail slide 1241ζ is attached to the ascending neighbor 118, and the upper slide rail 124 is supported by a pair of left and right upper slide rails 126 attached to a support frame 125 on the machine frame 8 so as to be vertically slidable. .

The lower border 119 is attached to a lower rail moving base 127, and the lower rail moving base 127 is supported by a pair of left and right lower sliding rails 128 attached to the lower end of the support frame 125 so as to be vertically slidable. The lower boundary neighbor 119 is biased in the downward direction by a spring 131 suspended between its right and left side hook hook pins 129 and a spring hook pin 130 on the machine frame 8 side.

The upper bottom mold 120 and the lower mold 121 have a molding surface 13 corresponding to the shape of the damper to be manufactured, as shown in FIG.
2゜133 and a heater (not shown)
, each of which is attached to the rising neighbor 118 and the lower neighbor 119 via heat insulating plates 134 and 135, respectively.

The air cylinder 122 is fixed to the support frame 125 above the rising neighbor 118 via a pair of upper and lower mounting brackets 136 and 137, and its piston rod 138 is connected to the rising neighbor 118 via a connector 139. There is.

The cam mechanism 123 is connected to the machine frame 8 below the lower boundary neighbor 119.
A cam mount 140 mounted above, a horizontal cam shaft 141 rotatably inserted into the cam mount 140, a cam 142 and a cam lever 143 keyed to the cam shaft 141, Adjacent 118 and cam lever 143
and a cam driven roller 146 that is pivotally attached to the lower side of the Hirai adjoining 119 via a roller mount 145. After contacting the lower surface, the lower molding die 121 is formed to have the same radius from point P midway so that it does not move up or down even if the cam 142 rotates.

In the forming press apparatus 4 having the above configuration, normally the upper mold 120 and the lower mold 121 are vertically separated from each other by l, as shown in FIG. When the held material 51 is transferred to the forming press position I by intermittent rotation of the rotary table 2, the air cylinder 122 is extended in response to a command from the control device, and the raised adjacent part 118 is moved to the upper column moving table 1.
At the same time, the cam lever 143 rotates in the direction of the arrow in the 16th figure via the connecting rod 144 due to the lowering movement of the rising adjoining member 118, and the cam shaft 141 and cam 14
2 rotates in the same direction and by the same angle, so the cam 14
2, the Hirai adjacency 119 is passed through the cam driven roller 146.
is pushed upward, and the adjacent Hirai 119 is moved to the lower column moving platform 12.
7 and the lower rail 128 while being supported and guided.
It rises against 31.

At this time, the descending speed of the rising neighbor 118 and the rising speed of the Hirai neighbor 119 are approximately the same, and since the stroke of the Hirai neighbor 119 is set smaller than that of the rising neighbor 118, point P is the cam While the cam 142 rotates until it corresponds to the driven roller 146, the Hirai neighbor 119 continues to rise rapidly, and when the cam driven roller 146 reaches point P, the Hirai neighbor 119
9 rises to the upper limit, and the molding surface 183 of the lower molding die 121
comes into contact with the lower surface of the material 57.

On the other hand, at this time, the earth-acid mold 120 has been lowered to the imaginary line position shown in FIG. 16, but there is a slight gap between it and the material 5T.

That is, at this time, the upper bottom mold 120 and the lower mold 121
has a positional relationship with respect to the material 57 as shown in FIG.

Then, when the ascending neighbor 118 continues to descend further, the cam 142 rotates in conjunction with this, but the cam driven roller 146
After the cam 142 rotates, the Hirai adjacency 119 does not rise or fall at all after it exceeds the point P, and the lower molding die 121 remains in contact with the lower surface of the material 57. , from this state, the 19th
As shown in the figure, the raw material 57 is pressed by the upper bottom mold 120 and the lower molding mold 121, and the raw material 57 is heated and molded by the molding surfaces 132 and 133 thereof.

In this way, if the lower molding die 121 is brought into contact with and aligned with the material 57, and then the upper molding die 120 is lowered to press the material 57, the upper and lower molding molds 120,
There is no relative positional shift between the material 121 and the material 57, and it is possible to prevent vertical vibrations of the material 57 just before pressing, so that the material 57 can be formed very reliably.

Moreover, during this pressing, the cam driven roller 146
Since it corresponds to the same radius part beyond the P point of 42,
The press load is applied to the lower molding die 121, the heat insulating plate 135, the Hirai neighbor 119, the roller mounting base 145, and the cam driven roller 146.
The cam mechanism 12 acts on the camshaft 141 in the radial direction through the cam 142 and does not cause a torsional load.
3, it is sufficient to simply lift the lower boundary adjacent 119 side against the spring 131, and therefore its strength is significantly increased, which has the effect of suppressing wear and the like to a minimum.

It is possible to adsorb the product 177 to the product receiving surface 166 or to blow up the adsorbed product 177 to make it float.

The upper material punching mold 149 is attached to the ascending neighbor 147, and has a product pressing surface 1γ8 having the same shape as the molding surface 132 of the epithelial mold 120, and has the same inner and outer diameters as the movable mold 164. The upper material punching die 149 is provided with an inner diameter punched piece discharge hole 180 in a cross shape for discharging the inner diameter punched piece 179.

The link mechanism 151 is interposed between the fixed bracket 181 at the upper end of the support frame 125 and the rising neighbor 147,
It consists of two links 182 and 183 that are pivotably attached to each other by a pin 184, and the link 182 is attached to a fixed bracket h.
l 8H Adjustment bracket 185 installed to allow vertical adjustment
The link 183 is pivoted to the mounting bracket 187 attached to the raised neighbor 147 by a pin 186.
It is pivotally connected by 88.

Air cylinder 152 is attached to lateral pivot pin 19 on trunnion bracket 189 mounted behind support frame 125.
The piston rod 191 is projected from the insertion hole 192 of the support frame 125 to the front side, and the link 182 is supported by the pin 1841.
, 183, and when the air cylinder 152 is extended, the link mechanism 151 is extended to lower the rising adjoining member 147, and near the time of maximum extension, both are punched by the punching molds 149 and 150. Material 57 to product 177
It is configured to punch out.

The cam mechanism 153 is mounted on the machine frame 8 below the Hirai adjacency 148.

After contacting the lower surface of the cam 195, the lower punching die 150 is formed to have the same radius from the middle so that it does not move up or down even if the cam 195 rotates.

In the punching press device 5 having the above configuration, the upper punch die 149 and the lower punch die 150 are normally vertically separated from each other, so that the material 57 formed into a predetermined damper shape by the forming press device 4 is When the material is held on the rotary table 2 by the material holding mechanism 61 and transferred to the punching press position J by intermittent rotation of the rotary table 2,
The air cylinder 152 is extended by a command from the control device, and the links 182 and 183 of the link mechanism 151, which were in the bent state, are extended as shown by the phantom lines in FIG. 21, and the rising neighbor 147 is moved upward. It begins to descend while being guided by the upper finger rail 155 via the platform 154.

At this time, the air cylinder 152 extends at the same speed, but since the configuration is such that the rising neighbor 147 is lowered via the link mechanism 151, the descending speed of the rising neighbor 147 is at its maximum at the start of descent, and the link As mechanism 151 extends, it gradually slows down.

On the other hand, when the rising neighbor 147 descends, the connecting rod 197
The cam lever 196 rotates in the direction shown by the arrow i in FIG. The column 148 is pushed upward, and the column 148 rises against the spring 160 while being supported and guided by the lower slide platform 156 and the lower slide rail 157.

At this time, the rising speed of the Hirai neighbor 148 is at its maximum at the beginning of the rise, similar to the rising neighbor 147, and gradually becomes slower.

Then, until the cam driven roller 199 corresponds to the Q point of the cam 195, the Hirai adjacent 148 continues the upward movement, and after the cam driven roller 199 exceeds the Q point, the Hirai adjacent 148
8 reaches the upper limit, and the movable die 164 of the lower punching die 150
The product receiving surface 166 of is maintained in surface contact with the lower surface of the material 57.

At this time, the upper punch punch die 147 has descended to the imaginary line position shown in FIG. 21, but there is a slight gap between the product pressing surface 178 and the material 57, ,15
0 has a positional relationship with respect to the material 57 as shown in FIG.

When the product receiving surface 166 of the lower punching die 150 comes into contact with the material 57 as shown in FIG. The suction force l from the hole 113 causes the material 57
is attracted to the product receiving surface 166 of the movable mold 164 and is in close contact with the product receiving surface 166. Therefore, even if there is a very slight positional deviation between the material 57 and the product receiving surface 166, the adsorption completely prevents the positional deviation. It can be done.

The rising neighbor 147 descends further while gradually slowing down its descending speed, and after the product pressing surface 178 of the upper punch punching die 149 matches the material 57, the σζ product receiving surface as shown in FIG. With the material 57 being sandwiched between the upper and lower punches 166 and the product pressing surface 118, the movable mold is moved integrally with the upper punch removing mold 149 while resisting the spring 263 by lowering the upper punch removing mold 149. The die 164 descends, and the upper punch die 149 becomes the lower punch die 1.
Since the material 57 is relatively fitted between the inner and outer fixed molds 162 and 163 of the inner and outer fixed molds 162 and 163, the material 57 is punched and separated into a product 177 and an inner diameter punching piece 119 between the inner fixed mold 162 and the upper punch punching mold 149. At the same time, the product 177 and the outer diameter punched piece 200 are separated by punching between the needle fixing mold 163 and the upper punch punching mold 149, and when punching the product 177 from this material 57, , the link mechanism 151 is near the maximum extension, and compared to the unit extension amount of the air cylinder 152, the rising neighboring 1
47, that is, the amount of descent of the upper punch punch die 149 is very small, so the punching torque at that time is very small. Therefore, the product 177 can be punched sharply from the material 57, and the product 177 is The fraying of the threads is completely eliminated and the quality is significantly improved.

When the upper punch punch die 149 reaches its lower limit and punching is completed, the solenoid valve 1γ0 operates, and the injection hole 16 is released from the flexible tube 111.
Compressed air is injected upward through 9, and the inner diameter punched piece 17
9 is discharged to a take-out position (not shown) through the inner diameter punched piece discharge hole 180 of the upper material punching die 149, and the outer diameter punched piece 2
00 is lζ on the rotary table 2 from the material holding mechanism 611
remains retained.

2 undergoes a contraction operation, and the rising neighbor 147 rises, and in conjunction with this, the Hirai neighbor 148 descends, and both punching molds 1
49.150 is moving away up and down, but at this time,
The cam mechanism 153 operates in the opposite manner to that described above, and first the ascending neighbor 1
47 rises and the upper material removal mold 149 begins to rise, the movable mold 164 is pushed up by the spring 263 and rises together with the upper material removal mold 149, and the movable mold 164

After the σ engagement, only the upper material punching die 149 rises independently.

At this time, the punched product 111 remains adsorbed to the product receiving surface 166 of the movable mold 164, and the Dotan punching mold 1
Since the side 49 rises first, the product 177 can be peeled off from the upper material removal mold 149 very well, and the product 177 does not stick to the upper material removal mold 149 and rise.
7 can be stably held on the lower punching die 150.

After the upper material punching die 149 starts its upward movement, the Hirai adjoining die 148 is lowered by the cam mechanism 153, and the lower punching die 150 descends while holding the product 177, thereby performing a series of punching operations. is completed.
