Description

[Detailed Description of the Invention] "Industrial Application Field" The present invention is applicable to processing work materials such as shaped steel and steel plates.

To set the dimensions of the workpiece to be machined, first use the scale mentioned above to move the dog to the position of the dimension to be machined, and then move the dog to that position using a pad or bolt. Currently, the dog is fixed, and the workpiece is positioned by abutting against the dog to perform processing. For this reason, it takes a lot of time to position the dog, especially when the dog has to be positioned every time the machining dimensions are changed. In this case, the machining length must be set by adding 172 mm, which is the width of the cutting tool, which is extremely cumbersome. There was a problem that it was not easy to obtain processing dimensions. On the other hand, the vertical direction (hereinafter referred to as the Y-axis direction) is not used much because it is often used for cutting steel plates, etc., but when punching etc.
Some types position the workpiece by hitting it against a backing plate. Even with such a product, after the worker uses a scale to move the light plate to the position of the processing dimensions,
Because they were fixed with bolts, nuts, etc., there were problems similar to those mentioned above, such as poor work efficiency and difficulty in positioning with high precision.

A rail 54 is laid on the pedestal 52 along the longitudinal direction of the base 48. A holder 56 is attached to the rail 54 via two linear motion bearings 55.
Attach it so that it can run freely along 4. Each linear motion bearing 55 holds the rail 54 irremovably and movably. Therefore, the holder 56 is adapted to run parallel to the base 48 by means of the rail 54 and the linear motion bearing 55. A motor 58 is fixed to the holder 56 via a motor base 57. The motor 58 is connected to an output shaft 59 via a coupling 60 to a gear shaft 61 positioned on one axis.

The mounting plate 66 is fixed to the holder 56 via a spacer 67. In this way, the output shaft 5 of the motor 58
9 and the rotating shaft 65 of the rotary encoder 64 are arranged on one axis, the amount of rotation of the motor 58, that is, the amount of feed due to the meshing of the pinion 62 and the rack 53 is directly transmitted to the rotary encoder 64.

Further, as shown in FIG. 8, a height adjustment bolt 68 is interposed between the holder 56 and each linear motion bearing 55 so that the backlash between the pinion 62 and the rack 53 can be adjusted.

To adjust the height, loosen the bolt 56a that fixes the holder 56 and the linear motion bearing 55, and then turn the height adjustment bolt 68. Since the tip of the holder 56 is in contact with the linear motion bearing 55, the holder 56 moves vertically with respect to the linear motion bearing 55, and as a result, the nion 62 also moves in the direction toward and away from the rack 53, so that the engaged state can be freely maintained. It can be adjusted to

The bolt 56a is inserted through a long hole in the holder 56 and is screwed into the linear motion bearing 55. A stop arm 69 is further pivotally attached to the holder 56 so as to be swingable.

Further, the body 4 is provided with a stopper device B for the Y axis. The stopper device WB includes a rail 54 and a rack 5 on the fuselage 4 instead of the base 48 in the stopper device A.
The stopper device A has exactly the same configuration as the stopper device A described above except for the provision of the stopper device A. However, the amount of movement of stopper device B, that is, the range in which positioning for processing can be determined, is smaller than that of stopper device A.

Next, the sizing method of the processing machine, that is, the method of setting machining dimensions will be explained. First, the case of cutting a long workpiece will be explained. As shown in FIG. 8, after starting at step 1.

In steps 2 and 3, machining conditions are input using the input device 2. As processing conditions for the above-mentioned cutting, the blade width P and cutting length are input. At this time, since the workpiece is simply cut, the Y-axis stopper device B is unnecessary. Therefore, the stopper device B for the Y axis is
The stop arm 80 is returned to a predetermined return position and stopped (.Next, proceed to step 4, and calculate the target value X0 for moving and positioning the stopper device A. That is, the above-mentioned blade width Find 172 of P and add the value of 172 of the blade width P to the cutting length to calculate the target value X0.At this time, when inputting 172 of the blade width P in step 2 and step 3 above, There is no need to calculate the value of 172 for the blade width P. Therefore, in step 5, the stop arm 69 of the stopper device A is moved from the center of the processing blade consisting of the movable blade 6 and the fixed blade 9 to Xo-L+1/2.
Move to position P. The movement position of the stop arm 69 is detected by the rotary encoder 64 and inputted to the microcomputer in the control box 1, and the movement position is transferred to the microcomputer in the control box 1.
Now, the current position of this adopted stop arm 69,
It is compared with the target value X0 to determine whether the stop arm 69 has reached the target value X0.

Stop arm 69 is at target value X. Repeat steps 5 and 6 until . When the stop arm 69 reaches the target value X0, the movement is stopped at this target value X0, cutting is performed in step 7, and the process is completed in step 8.

It is assumed that the cutting process in step 7 is performed on a predetermined number of pieces at will. In addition, in steps 2 and 3, a plurality of lengths to be cut and the number of pieces to be cut are inputted in advance, and in step 9, each time a predetermined number of pieces are cut at each target value, the number of pieces to be cut is inputted. Next, it is determined whether or not all the cutting operations have been completed, and if not, the process returns to step 4, thereby allowing the stop arm 69 to be sequentially moved to the next target value for processing. in this case,
The stop arm 69 is configured to index and move the target value to be processed next, using the previous target value as a reference point.

The movement of the stop arm 69 is controlled by a command from the microcomputer in the control box l, and when the motor 58 is driven, the pinion 62 rotates and the pinion 62 is engaged with the rack 53, so that the holder 56 runs along the rail 54. Since the stop arm 69 is attached to the holder 56, the stop arm 69 moves on the roller 50, 51, and the rotary encoder 6
4 detects the current position of the stop arm 69, and the current value is the target value X. When it reaches this point, the drive of the motor 58 is stopped by a command from the microcomputer. Then, the workpiece is moved to the support section 4 until it hits the stop arm 69.
If it is cut after being inserted from 2, it will be cut to a preset length with the cutter width 172, which will be the cutting margin, corrected.

Next, the case of punching as shown in FIG. 9 will be explained. First, as shown in FIG. 10, after the start of step 1, processing conditions are manually set in step 2 and step 3. As for the machining conditions, in punching machining, there is no need to consider the cutting allowance at all, so input the blade width as zero. Then, as shown in FIG. 1, machining dimensions in the X-axis direction are written in each memory 4 dedicated to the X-axis, dedicated to the Y-axis, and further dedicated to the number of pieces.

In other words, one channel of the X-axis dedicated memory has 1.0 as shown in FIG. By inputting , and inputting t into one channel of the memory dedicated to the Y axis, the position of the first punching hole H8 can be determined.Moreover, since three holes are to be punched at an interval of 1t, 2. The punched holes H1 to H1 can be positioned by manually setting the interval t2 and the number 3 in the channel. Next 3
The interval t3 is manually added to the channel, and the interval t is added to the 4th channel.
By inputting 4 and the number 3, the positions of punching holes H4 to H& can be determined. Furthermore, by inputting the interval t into channel 5 of the Y-axis dedicated memory, then inputting the above interval -t4 into the 6th channel of the X-axis dedicated memory, and further inputting 3 pieces into the number dedicated memory, punching holes H7 to You can position H9. If you input the interval -t4 in the 7th channel, and the interval -1 and the number of pieces 3 in the 8th channel, punching holes HI6 to HI! If the positioning is completed and the end is input to channel 9, all the punching processing conditions shown in FIG. 9 have been input. In step 4, calculation processing is performed to enable movement and positioning of the stopper devices A and H based on the above various conditions. Next, in step 5, the stopper devices A and B are first moved according to the contents of one channel, and the current position of the movement is detected by the rotary encoder '64 of each stopper device A and B. In step 6, it is determined whether each stopper device A, B has reached the set position for one channel. Steps 5 and 6 are repeated until the stopper devices A, B reach their set positions. When each stopper device A, B reaches the set position, punching is performed in step 7, and after the punching, the process proceeds to step 8. In step 8, it is determined whether or not there is an end mark in the next channel, and the end mark is If there is no
In the next step 9, search for the setting position of the next channel,
After performing calculation processing, step 5. Proceed to step 6 and step 7, perform punching in the same manner as above,
Punching is performed according to each channel in sequence until the end mark is found.

As described above, each of the stopper devices A and B allows various types of processing such as punching to be performed by determining the position of the workpiece to be processed.

In addition, the stop arm 9 of each of the above-mentioned stopper devices A and B
, 80 are made tough by hardening or the like.

"Effects of the Invention" As described above, according to the sizing method and device for a processing machine according to the present invention, not only the work efficiency is improved by the numerical control method, but also the length of 172 mm, which is the width of the cutting tool that should be the cutting margin, can be improved. Since the cutting length can be set by correcting the cutting length, the machining dimensions can be determined with extremely high accuracy, which is extremely convenient.
