BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a flat die type rolling machine for rolling gears, splines, screws, etc., in which the type of a work is determined and a corresponding working die is automatically selected and mounted. The structure of the rolling machine.

[0002]

2. Description of the Related Art In order to process a plurality of types of workpieces on a single rolling machine, a type of rolling die suitable for the processing specifications is selected according to the type of the work, and the rolling die is formed. Must be worn. Conventionally, the exchanging of the rolling dies has been performed manually by an operator, but since it is extremely inefficient, mechanization has come to be performed. One example is disclosed in Japanese Utility Model Laid-Open No. 1-60734. This is achieved by suspending a plurality of sets of die holders that hold rolling dies on a bracket that is provided movably on two left and right linear rails installed in the front-rear direction along the axis of the main axis of the rolling machine. The flat dies for rolling are automatically exchanged and mounted on the rolling slides of the rolling machine by moving the die holder sequentially. In addition, actual Kaihei 1
In the technique disclosed in Japanese Patent Application No. 114130, a rotary table rotatable in the horizontal plane on each of the left and right sides is installed at the top of two columns of a rolling machine, and a rolling die is held by a bracket on the lower surface thereof. By automatically suspending and supporting a plurality of die holders and rotatingly positioning a rotary table, a flat die for rolling is automatically exchanged and mounted on a rolling slide of a rolling machine.

Problems to be Solved by the Invention
The rolling machine with an automatic tool changer disclosed in the above publication has a configuration in which up to three or four sets of flat dies for replacement are normally held, and the work of several rolling sites is continuously rolled per one. Suitable for fabrication. However, in this tool changing apparatus, since the holder of the flat die for replacement is arranged on the linear rail in the front-rear direction of the rolling machine, all of the number of the holders held are forward of the rolling slide of the rolling machine. Alternatively, it is necessary to be able to be accommodated behind. On the other hand, since the rolling machine cannot have only an excessively long rail of the tool changer due to its dimensional restrictions in the front-rear direction, the number of flat die holders for replacement is limited to about four sets.
Although it has more flat die holders, it is difficult to manufacture.

The rolling machine structure of Japanese Utility Model Laid-Open No. 1-114130 can be compactly assembled with an automatic tool changer, but both rotary tables are placed in a narrow space between two columns. Must be passed through without contact, and of course this ring is narrow and difficult to make structurally strong. Further, since the rotary table ring is supported at the upper end of the column, the diameter of the rotary table ring cannot be unbalancedly increased in order to provide a stable support structure. Therefore, also in this case, the number of flat die holders held is limited to at most about five sets.

As described above, in the conventional automatic tool changer for a rolling machine, since the number of sets of flat dies held for the change is small, many types of flat dies must be prepared. Can not. Therefore, even if it is possible to cope with one type of work having one rolled portion at several locations, it cannot sufficiently cope with a plurality of types of work having multiple rolled portions. Was. On the other hand, with the recent introduction of FMS, a plurality of types of workpieces are processed at any time on a single production line. When workpieces of different types are mixedly machined, there has been a demand for a tool changing function that can automatically cope with the workpieces. According to the present invention, a plurality of types of workpieces having a plurality of rolling portions are automatically selected and mounted on a rolling machine without the need for manual instructions for machining dies corresponding to the type of workpiece. An object of the present invention is to provide a flat die-type rolling machine capable of coping with the following. Another object of the present invention is to accommodate a large number of processing dies in a compact manner and to facilitate the mounting and dismounting of the dies.

[0006]

In order to achieve the above object, a flat die type rolling machine according to the present invention is provided with flat die storing means for storing and storing a large number of types of flat dies. Work discriminating means for issuing a command for discriminating the type and selecting the type of flat die required for machining the work, and between the flat die storing means and the rolling slide of the rolling machine according to a command from the work discriminating means. The present invention is an automatic flat die exchanging type rolling processing apparatus having a flat dice exchanging means for exchanging a used flat dice and a flat dice to be used and detached therefrom. The flat die storage means is composed of a number of flat die holders movably arranged on an annular locus. The flat die holder holding a required type of flat die is stored by a command from the work discriminating means. It is intended to be positioned at a delivery point between the means and the rolling machine.

[0007]

The feature of the type of the work to be rolled is detected by the work determining means, and a command for selecting the type of the flat die required for processing the work is issued from the work determining means. The flat die changing means operates according to the flat die selection command. First, the used flat die is removed from the rolling slide of the rolling machine and returned to the flat die storage means. Next, a flat die of a required type to be used is extracted from the flat die storage means and mounted on a rolling slide of a rolling machine. When a required type of flat die is mounted on a rolling machine, the work is rolled by this.
When one work has a plurality of rolling processing locations, a command from the work discriminating means is also performed correspondingly, and a different type of flat die is exchanged and mounted on the rolling slide by the flat die exchanging means, The work is rolled. When a used flat die is not mounted on the rolling slide at the beginning, a required type of flat die is immediately mounted by the flat die changing means.

Next, the processing of the work W by the rolling machine of the present embodiment will be described. In FIG. 3, the work W carried into the carry-in entrance 17 at the left end of the work supply / discharge device 102 is shown.
Is moved laterally by the supply swing conveyor 76 and sent to the end standby position 75. From the standby position 75, the workpiece is lifted upward by the supply work lifter 77 and placed on the temporary receiving table 21 of the work determination device 103. The work W is determined by the work determination device 103. If the work W can be processed by a flat die already mounted on the rolling machine, the work W is set on the rolling spindle 1 by the work temporary receiving stand 78 and subjected to the rolling process.

When a predetermined flat die is not mounted on a rolling machine, such as when the work W is different, a command for selecting a processing flat die is output by a discrimination signal corresponding to the work W. In accordance with the selection command, the flat die storage device rotates and firstly, the flat die storage device 1 is already mounted on the rolling machine.
The left flat die storage position of the set of flat dies is set to the flat die transfer position. The left flat die is removed from the left rolling slide 3a by the flat die exchanging device, and stored in the left flat die storage section. Similarly, the flat die storage device is rotated so that the right flat die storage position is at the flat die transfer position, the right flat die is removed from the right rolling slide 3b by the flat die exchanging device, and the right flat die storage unit is removed. To be stored.

Next, the flat die storage device rotates, and the left flat die of the designated flat die (one set of left and right) is positioned at the flat die transfer position. The positioned flat die is removed from the flat die storage device by the flat die exchanging device, and is mounted on the left rolling slide 3a. Similarly, the flat die storage device rotates, the specified right flat die is positioned at the flat die transfer position, the right die is removed from the flat die storage device by the flat die exchange device, and is mounted on the right rolling slide 3b. Is done. If no dies are mounted on the rolling slide, the operation of storing the flat dies is omitted. In this way, a predetermined set of flat dies is automatically selected according to the work W, and is exchanged and mounted on the rolling slides 3a and 3b of the rolling machine.

Then, the workpiece W set on the rolled spindle 1 is subjected to the rolling process by the workpiece temporary receiving stand 78. 1
When a plurality of rolling processes having different shapes are successively performed on the workpiece W, the workpiece W is automatically set in the same manner as described above and is automatically replaced with a predetermined die while the workpiece W is set on the rolling spindle. Processing is performed. The processed work W is extracted by the work extractor 79, lowered by the discharge work loader 84, further sent to the right outlet port 18 by the unloading swing conveyor 85, and discharged out of the machine.

Hereinafter, the work discrimination and the exchange of the flat dies will be described in detail. As shown in FIG.
, The work W is supported by the tail center 23 and the head center 22, and the axial dimension L of the work W is measured by a cylinder 23 a having a position detection function directly connected to the head center 23. In addition, the contact W and the proximity sensor 26 installed in a direction perpendicular to the
Is measured for the diameter d of the particular part of. The measured values of the axial dimension L and the outer diameter dimension d of the work W are input to the comparator, and one of two modes, eight modes according to the measured values, is output from the comparator. This mode signal is input to the PC as a work determination signal, and the type of the work W is specified by a program in the PC, and further, the type of the flat die 10 for processing the specified work W is selected. In this way, a maximum of 64 types of workpieces can be determined by selecting the measured value and the set value of the comparator.

The order of extracting a set of flat dies from the flat die storage device 104 and mounting them on the rolling slides 3a and 3b of the rolling machine and the path thereof are shown in FIGS. 11 and 13A for the left side.
12 and 13 (B) show the right-hand side. In the case of the left side, the rotary disc 61 of the flat die storage device 104 is rotated and indexed by a signal from the work discriminating device 103, and a required flat die 10m for the left side is obtained.
Is held at the position of the delivery location 97. The hanging rails 86 of the flat die changing device 105 are matched with the hanging rails 66 of the flat die storage device 104 of the flat die holder 40m (FIGS. 11A and 13A). At this time, the left rolling slide 3a is set to the raised position (FIG. 13C). Next, the chuck 36 of the flat die changing device is engaged with the moving pin 41 of the flat die holder 40m,
5 is released (FIG. 11b). Next, the transfer cylinder 35
To move the flat die holder 40m to the suspension rail 86 of the flat die changing device (FIGS. 11c and 13).
A).

Next, the delivery point 97 is the left frame 14
Since it is closer to the side a, it is moved to the right by the left and right moving cylinder 34 of the flat die exchanging device 105 in order to avoid interference (FIG. 13A). Next, the ball screw rod 32a is driven by the servo motor 30 of the flat die changing device to pull the flat die holder 40m forward, so that the front-rear direction is the same as the position of the left-side rolling slide 3a and the mounting portion (FIG. 11d). , FIG. 13A). Flat die changing device 1
05 to the left by the left and right moving cylinder 34,
The left rolling slide 3a in the raised position is pressed against the mounting surface of the flat die fixing base 6 on the tool post 5 (FIG. 13A).
). In this way, the flat die 10m is fixed by the receiving metal 112 and the clamp claw 113 of the flat die fixing base 6, and is attached to the left rolling slide 3a.

The same applies to the case where the required right flat die 10n is mounted on the right rolling slide 3b, except that the direction and the right and left of the path are different. Note that, in this case, the right rolling slide 3b is at the raised position, and the left rolling slide 3a is at the lowered position (FIG. 13D). Further, since the delivery point 97 is shifted toward the left frame side 14a, there is no interference as in the movement from the delivery point 97 to the right rolling slide 3a, and therefore, as shown in FIG.
Such a lateral movement process is unnecessary. When the flat dies 10m and 10n are removed from the rolling slides 3a and 3b and returned to and stored in the flat die storage device 104, the reverse order and path are followed.

Since the flat dies have the same shape, it is not necessary to prepare a plurality of storage places having a special shape, and storage is facilitated.

A die is selectively rolled and processed each time based on the work discrimination information, and the temporary receiving stand 21 of the work discrimination device 103 is used.
Since the workpiece is inserted into the rolling spindle by the workpiece setter 78 and the workpiece determination position and the processing position are close to each other, there is almost no occurrence of inconsistency in the workpiece information due to mixing of the workpiece, falling off, or stopping the stroke. Therefore, the predetermined processing is reliably performed.

In the embodiment, since the work discrimination information is two dimensions, that is, the outer diameter dimension and the axial dimension of the work, the amount of information is significantly increased as compared with using either one of the information. On the other hand, a large amount of information can be obtained by combining the image processing device with the workpiece discrimination information.
In many cases, the amount of information obtained by measuring one dimension is appropriate, and a smaller, simpler, and less expensive discriminator can be obtained. In addition, more information can be obtained by attaching a barcode or other identification tag to the work and determining the work type, but it is not economical because the work of attaching these to the work is added. In the embodiment, since the determination is made only by measuring the pre-processed dimension of the work itself, no extra work is required, and there is no problem such as incorrect mounting of the identification tag.

The transfer point 97 for transferring the flat dice 10 between the flat die storage device 104 and the flat die exchanging device 105 may be located at the center of the frame. However, in this case, the flat die exchanging device 105 and the flat die rolling slide 3
In order to avoid such interference, the frame interval must be increased. On the other hand, in the embodiment, since the position of the delivery location 97 is shifted to the left side (or the right side) of the frame, the distance between the frames 14a and 14b can be reduced.

A plurality of flat dies are suspended in the flat die storage device 104.
Since flat dies are mounted on a and 3b so that the die surfaces face each other, the mounting direction of the flat dies must be considered. In the embodiment, since a pair of flat dies can be attached to the flat die storage device 104 facing each other or facing each other, when the flat dies are mounted on the flat die rolling slider 3, the flat dies can be exchanged only by pulling out the flat dies. And so on. When a flat die is mounted on the flat die storage device 104, one set of flat dies is separately mounted on two flat die storage devices as in the case of the conventional example.
Since a pair of flat dies can be mounted adjacent to each other, there is no need to mount the flat dies in a place different from the designated place or to mount the dies incorrectly. Therefore, the flat die can be securely and easily attached without moving to a remote position as in the related art.

If the flat die storage device or the flat die exchange device is provided with a rotating portion so that it can be set in any direction on the left and right, the mounting direction of the flat die to the flat die storage device may be arbitrary. The flat die rolled slider is OB
Since the D dimension can be automatically corrected, the accuracy is good and the maintenance is easy.

FIG. 14 shows another embodiment of the present invention in which flat dies 10m and 10n are rolled into slide rolls 3a and 3a.
3b shows a path to be attached. Flat die storage device 1
04a is composed of a large number of flat die holders 40 moving on an annular locus having a straight part in the middle, and two delivery points for left and right are provided in the middle straight part,
Since it is positioned at each location,
There is an advantage that the path by the flat die changing device 105 is saved at one place.

[0038]

According to the present invention, when a plurality of types of workpieces are mixedly processed in a flat die type rolling machine, a flat die for machining corresponding to the workpiece is automatically selected and the rolling machine is formed. , It can be operated fully automatically without the need for manual operation for a flat die replacement command. Further, since the command of the flat dice exchange is automatically performed according to the type of the work in response to the signal of the work discriminating means, there is no mistake associated with the manual instruction and the time required for the flat dice exchange is reduced. Further, since the number of flat dies stored and stored is large and many types, it is possible to cope with a case where a plurality of types of workpieces having a plurality of rolled portions are mixedly processed. And a storage device that can mount many types of rolling tools including a rolling machine is provided in one processing device, so that many processing dies can be stored compactly, installation space can be reduced,
This has reduced equipment costs.
