Figure 1 DETAILED DESCRIPTION OF THE INVENTION An example of attaching the operation like status display device 20 of the present invention to a rolling machine 1. The operating like status display device 20 includes a control mechanism C for receiving the data processing form status, and display D displaying the first, second storage unit ME1, ME2 and storage thereof for storing data from the control mechanism Is provided.

The input data to the control mechanism C includes:
In the present embodiment, a frequency control mechanism I for controlling the number of revolutions of the forming roller, that is, the number of revolutions of the drive motor M (the number of revolutions of the motor may be directly measured or a motor current value may be used).
, A feed speed of the mandrel 2, that is, a feed speed detector E such as an encoder attached to the mounting frame 17 of the backup roller 4 and emitting a pulse signal at predetermined intervals.
From the oil pressure detector P of the supply pressure oil to the advance / retreat cylinder 7 of the backup roller 4 as a pressing force, a change in the diameter of the material W, that is, a growth speed detection signal from the material diameter detection sensor 11, and the like. Let me enter.

The control mechanism C applies the data of the machining shape situation in the first storage unit ME1 every predetermined time. An example is shown in FIG.
Shown in The figure shows the motor current a, the pressing speed for the material, ie, the forward speed b of the backup roller 4, the growth speed c of the diameter of the material by rolling, the number of rotations d of the material, and the application of the material to the forming roller by the backup roller 4. The change in the pressure e is applied to the first storage unit ME1 at regular intervals and stored. However, the number of rotations of the material is a change in the number of rotations of the forming roller and a change in diameter due to the rolling of the material (outside diameter detection sensor 1
1) is calculated. Display D
Displays these every cycle.

[0019] The first storage unit ME1 is intended for temporarily storing, it has enough space to store the processed form status data for one cycle. Among the data stored in the first storage unit ME1, data that needs to be stored, for example, data at the time of work at a preset time every day (for example, at the start of work), data after tool exchange, and the like are the second data. It is stored in the storage unit ME2. The second storage unit ME2 is desirably a large-capacity storage device for storing various product processing data.
Use a storage device whose data is not erased even when the power is off. The processed data in the second storage unit ME2 may be data calculated in advance on a desk or data obtained by correcting data applied from the first storage unit ME1.

[0020] In the above structure, the continuously processed like situation is first
The information is stored in the storage unit ME1 and displayed on the display D. Then, if necessary, it may be required to check a change in the current machining state with respect to the standard work stored in the second storage unit ME2. In this case, it is possible to determine whether the current work is good or not by displaying and comparing the standard work with the above-mentioned standard work, so that it is easy to find a worn or damaged part. An example is shown in FIG. The figure shows the motor current and the growth speed of the material. In the figure, a1 and c1 are the motor current and the material growth speed data stored in the second storage unit ME1, respectively, and a2 and c2 are the currently processed data. Or the first storage unit ME
1 shows the respective new data stored. In addition, it is preferable to display both of them by color. If the difference between the current data displayed on the display D and the data during normal operation is extremely large, it is desirable to issue an alarm.

The control mechanism C has a calculation function for detecting the difference between the two and calculating the two at the position indicated by the cursor K on the display D, and the display D has a function for displaying them. Is preferred. In the figure, H indicates the display unit. Thereby, it may be determined whether or not the difference is within an allowable range, and the difference may be automatically applied to the automatic operation control mechanism CPU of the rolling machine, or may be manually added with a slight correction value. Thus, if there is a danger of damaging the device at times, it is desirable to make an emergency stop.

[0022]

When by the above-described as the present invention according to the present invention, the rotational speed of the forming roller in the rolling machine, pressure relative to the mandrel, measured every predetermined time by the control mechanism processing like status of changes in the diameter of the material, which stores the, display overlaid with a previously stored predetermined data to a display, it is so arranged to display the operation like situation, monitoring is difficult, yet the monitoring can be carried out repeatedly. At this time, when the control mechanism is provided with calculation means for the standard and display target data redundantly displayed on the display, it is immediately determined whether the calculation is out of the allowable range, and the command is sent to the automatic control mechanism of the rolling machine. Can be provided.
