Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This idea has a punching section and a cutting section, and is movable in the front and rear directions. Turret pan with a swingable side chute on the side table on the workpiece delivery side. Regarding Chipres.

0002

[Conventional technology]

Conventionally, for example, turret punch presses have a center tap fixed to the punching part. There is a carry-in side and a carry-out side on the left and right sides that can be moved forward and backward, respectively. There are side tables.

0003 Then, the workpiece is carried from the carry-in side table to the center table, and then The workpiece is punched out on the center table of sent to the top.

0004 The workpiece (product) sent onto the unloading side table is unloaded by the unloading function. e.g. blanking with a separating device. Transported to Shah. The cutting device separates the product from the workpiece. The current situation is that they are classified as follows.

[0005] By the way, in the turret punch press below the line mentioned above, the processing When attempting to transport the workpiece to the side, an unloader installed in a separate unit is used. In addition to requiring equipment with a loading function, a certain amount of space is also required. Ru.

[0006] In addition, even equipment equipped with an unloading function can grip and transport processed workpieces. The problem is that the workpiece is easily scratched because it slides on the exit side table. There was a problem.

[0007] Furthermore, small-sized products that are cut in large numbers from regular length materials must be unloaded one by one. It was difficult and troublesome to transport the equipment using a device equipped with a shipping function.

[0008] A turret punch press equipped with a workpiece delivery mechanism is already known, but its The workpiece unloading mechanism uses a pinch roller to send out the workpiece, so it is difficult to remove the pinch roller. There is an inconvenience that the size of the workpiece that can be carried out is limited depending on the attachment position.

[0009] Furthermore, punching and cutting of the workpiece to be processed is performed using a turret punch press or a turret punch press. The work is done on a shearing machine equipped with a cutting and cutting device, so the workpiece is small. It had to be reassembled at least twice, which caused problems in terms of processing accuracy.

0010 Therefore, in view of the above problem, we installed a separate section at the back of the center table and in front of the turret. A sub-punch is installed as a device, and a side table on the unloading side is also equipped as an unloading device. A side shooter is provided that can move up and down, and one end is suspended from the above-mentioned delivery side side table. The side shooter is moved up and down via a cylinder supported by a frame fixed at the bottom. A movable turret punch press has been proposed.

[0011]

[Problem that the idea aims to solve]

However, the side table moves forward and backward relative to the center table. Because of this, the side table does not have a heavy frame or frame like the conventional technology. If the cylinder is fixed hanging down, the side table will be heavier when moving, so the frame will be Vibration of the workpiece or cylinder may loosen the workpiece clamp and adversely affect machining accuracy. There was a problem with it dropping.

0012 The purpose of this invention is to solve this problem by keeping the side table lightweight. A turret equipped with a side shooter that reduces vibration and improves machining accuracy. Our goal is to provide punch presses.

[0013]

[Means to solve the problem]

In order to achieve the above purpose, this invention has a cutting section on the front side of the rotatable turret. A center table with A movable side table is provided, and a side shooter is installed on one side of the side table. A link device is provided that uses one end of the side shooter as a fulcrum and swings the other end. The side shooter is provided swingably through the turret punch press. Ta.

[0014]

[Effect]

The side shooters of the side tables are installed on both sides of the center table. The workpiece W brought in from the other side table that is not provided is placed at the center. - Clamped after positioning the origin on the table. Furthermore, move it on the center table. The machine is moved and positioned at the processing position of the turret.

[0015] Then, a part of the workpiece W is punched at the processing position of the turret and manufactured into a product. Ru. At this time, the workpiece W has a connection at a slightly small joint (called a micro joint). The product is completed.

[0016] Next, the workpiece W is clamped at the beginning, with the micro joint at the center. It is positioned at the cutting section provided on the table. Then, by the cutting section The product is separated from the workpiece and placed on the side table with one side shooter. Transported to bull.

[0017] At this time, the side table should receive the separated product with the side chute. The side shooter is moved in the front and back direction as appropriate so that it comes close to the cutting part. . Also, at this time, the side shooter is swung outward and downward by the link device, so the manufacturing The items slide out of the side chute and are carried out.

[0018] If the product is smaller than the workpiece W, the workpiece W is clamped first. In this state, it is positioned again at the processing position of the turret and the next product is punched out. child At this time, the side shooter is moved by the link device to support a part of the workpiece W. It is swung so that it is flush with the table. Also, the workpiece W can be sufficiently supported. In some cases, side tables are also moved back and forth as needed. stop Once again, the product is separated from the workpiece W by the operation described above, and the side shooter It is slipped off and carried out.

[0019] In this way, the work W is clamped at the beginning as long as there is space to punch out the product. As the product is repeatedly punched, separated, and transported in the same state, processing accuracy can be improved. It can be kept clean.

[0020] Also, even if the side table moves back and forth, vibrations will occur because the moving weight is small. The punching accuracy will not be adversely affected by loosening the work clamp.

[0021]

And center table 19 A carry-out side table 23 is provided on the side (right side in FIG. 6). Note that the top surface of each table above has multiple freeforms to support the moving workpiece. Bearings are provided as appropriate.

[0025] The center table 19, the carry-in side table 21 and the carry-out side table A carriage base 25 is provided in front of the cable 23 (lower in FIG. 6). There is. This carriage base 25 is connected to the carry-in side table 21 and the carry-out side table 21. The rails 27 and L on the lower frame 5 are integrated into the side side table 23. Slides in the Y-axis direction (vertical direction in Fig. 6), which is the front-rear direction, by the M guide 29. It is freely installed and driven in the front and rear direction by a feed screw 31 and a servo motor 33. It is now possible to do so.

[0026] On the other hand, the carriage base 25 is attached in the X-axis direction, which is the left-right direction (the left A carriage 35 is placed thereon, which is movable to the right (rightward). This carriage 35 , is driven in the left-right direction by a feed screw 37 and a servo motor 39. Ru. Furthermore, the workpiece W is clamped on the punching part 17 side of the carriage 35. A plurality of work clamps 41, for example two, are attached.

[0027] With the above configuration, when the servo motor 39 is driven, a key is sent via the feed screw 37. The carriage 35 is controlled to move in the X-axis direction. Work clamp on carriage 35 41 is attached, the workpiece (not shown) held by the workpiece clamp 41 The arc W is controlled to move in the X-axis direction. At this time, the workpiece W is - The upper surface of the table 19, loading and unloading side tables 21 and 23 - It is supported and moved by rolling bearings.

[0028] Also, when the servo motor 33 is driven and controlled, the carriage base is moved through the feed screw 31. The loading side table 21 and the unloading side table 21 are integrated with the base 25. The bull 23 is moved in the Y-axis direction. At this time, the work W is on the center table 19. It moves while rolling on the free bearing on the surface, but the loading and unloading side table Although the free bearings on the top of Les 21 and 23 are supported, are there any relative movements? There will be no rolling.

[0029] Thus, the workpiece W is held by the workpiece clamp 41 and its movement in the X-axis and Y-axis directions is controlled. the desired position of the workpiece W is positioned directly below the striker 15. At the same time, the desired punch 11 and die 13 are rotated and indexed to the processing position. Depending on the work, punching will be performed.

[0030] In FIG. 5 of the upper frame 3, a plate holding device 43 and a plate holding device 43 are installed at the lower portions of both left and right sides of the upper frame 3. A cutting punch 45 is attached. Therefore, punching is performed on the workpiece W. When the workpiece W is pressed, the workpiece W is pressed by the plate holding device 43 and the plate holding/cutting punch 45. After the pressing work W is prevented from moving, punching is performed.

[0031] The cutting process for separating multiple pieces from the workpiece W is performed using the plate presser and cutting pan. The cutting process is performed in a cutting section 47 that has a chip 45 attached to the upper frame 3.

[0032] The plate presser and cutting punch 45 in the cutting section 47 is as shown in FIG. A punch holder 49 is suspended from the upper frame 3, and a coil spring with low rigidity is attached to the punch holder 49. A hollow cylindrical punch guide 53 is provided via a hole 51 so as to be vertically movable. this A punch 57 is inserted into the punch guide 53 via a highly rigid coil spring 55. is provided to be able to move up and down.

[0033] A ram cylinder 59 is provided on the upper frame 3 directly above the punch 57. , directly below the punch 57, a die holder 62 equipped with a die 61 is attached to the lower frame 5. It is provided.

[0034] With the above configuration, low pressure oil is supplied to the ram cylinder 59, and the coil spring 51 is bent, and the workpiece W is pressed by the bottom of the punch guide 53, as shown in FIG. For example, the work W is for cutting A, B, or C of a small multi-piece product as shown in Fig. 4. (micro joint).

[0035] In this state, when high pressure oil is supplied to the ram cylinder 59, the coil The screw 55 also bends and the punch 57 descends to separate the small product separation portion of the workpiece W. Cut The separated small products are stored on a carry-out side table provided on the side of the cutting section 47. Sent to 23. Then, it is slid down from the side shooter 63 (described later) and carried out. .

[0036] Therefore, the workpiece W is processed by the cooperation of the punch 11 and die 13 in the punching section 17. A punching process is performed, and a cutting part 47 arranged on the side of the punching part 17 cuts the part. By working together with the punch 57 and the die 61, the cutting process for separating small products with multiple pieces is possible. administered.

[0037] Therefore, punching and cutting can be performed continuously without re-holding the workpiece W. As a result, high-precision processed products can be obtained.

[0038] Now, the side chute 63 that slides off the separated small products and transports them to the outside is , as shown in FIG. It is located at the center in the front-rear direction.

[0039] In this configuration, as shown in FIGS. 1 and 2, the side shooter 63 is located on the unloading side. The first brackets are provided in the front and rear near the center table 19 below the front table 23. It is pivotally supported by a first hinge pin 67 supported by a seat 65 and is supported so as to be swingable downward. has been done.

[0040] On the other hand, the bracket 65 at the bottom of the carry-out side table 23 allows the right side to be opened. 2 brackets 69 are fixed. The second bracket supported by this second bracket 69 A right triangular link plate that is pivotally supported by the hinge pin 71 and can swing downward. 73 are provided.

[0041] In order to swing this link plate 73, a , a third bracket 75 provided further to the right than the second bracket 69; The third hinge pin 77 supported by the third hinge pin 77 and the third hinge pin 77 supported by the Piston rod with pin joints attached at both ends supported by 4 hinge pins 79 A fluid pressure cylinder 81 equipped with a cylinder 81P is provided.

[0042] Furthermore, a horizontal elongated hole 83 is provided at the left end of the link plate 73, and the inner A fifth hinge pin 85 is configured to slide on the portion. Also, this fifth hinge pin Reference numeral 85 denotes an opening/closing bra provided hanging down near the center of the lower part of the side shooter 63. It is also supported by the bracket 87.

[0043] In addition, as shown in FIG. It is attached vertically, and the tip is in contact with the top surface of the link plate 73. When the piston rod 81P of the fluid pressure cylinder 81 is extended, the side shooter 63 is adjusted so that the top surface is horizontal. Also, the side shooter 63 is in a horizontal state. When it is on the top surface, it plays the role of supporting the workpiece W like other tables. is equipped with an appropriate number of free bearings. In addition, from 69 to 87 The link device 91 is made up of the following parts.

[0044] In the above configuration, the fluid pressure cylinder 81 is operated to house the piston rod 81P. When retracted, the link plate 73 rotates around the second hinge pin 71 as shown in FIG. Since it swings clockwise, the fifth hinge pin 85 slides inside the elongated hole 83. moved downward. Therefore, the opening/closing bracket 87 is also pulled downward. Therefore, the service The ID shooter 63 is opened by swinging to the right about the first hinge pin 67. Because of this, the product can be slid down and carried out.

[0045] As mentioned above, the operating mechanism of the side shooter 63 is simple and lightweight, so it is easy to carry out. The loading side side table 21 and the carrier are integrated together with the side side table 23. The ridge base 25 does not move in the Y-axis direction and cause vibration. Therefore, due to vibration Therefore, the workpiece W may shift from the workpiece clamp 41 and adversely affect machining accuracy. There is no such thing.

[0046] In addition, even when punching out a large number of small products from the work W as shown in Figure 4, it is possible to Punch it out as it is, cut it one after another with a plate presser/cutting punch 45, and make a side shooter. 63, it is efficient, space-saving, and maintains good machining accuracy. I can do it. Furthermore, since the side shooter 63 can be made sufficiently large, the size of the product is not restricted by.

[0047] Note that this invention is not limited to the above-mentioned embodiments, and may be modified as appropriate. Therefore, other embodiments may also be used.

[0048] For example, by extending the opening/closing bracket 87 of the side shooter 63 further downward, , the link plate 73 is omitted and the side shooter 63 is opened directly by a hydraulic cylinder. It can also be adapted to be closed.

[0049]

[Effect of the idea]

As can be understood from the explanation of the embodiments above, the original The workpiece clamped at a point position is positioned at the processing position of the turret and punched out. After machining, the workpiece is left in the initial clamp and the product is cut with a side punch. The separated product will slide out of the open side chute and be carried out. This enables efficient machining and requires less space as a machining system. It becomes.

[0050] Therefore, when taking many small products into a large workpiece, one product After the workpiece is separated from the side chute and carried out from the side chute, the workpiece remains in the original clamp. It is returned to the turret and punched, which is efficient and provides good processing accuracy. can be kept.

[0051] In addition, the side shooter is now swung by a link device that has a simple structure and is lightweight. Therefore, even if the side table moves back and forth, it will not shake due to the weight of the linkage. No movement occurs. Therefore, the work clamp becomes loose and has a negative effect on machining accuracy. It will not cause any damage.
