The accuracy of the hole directly affects the quality of the product after bending. An efficient hole arrangement system can ensure that waste can be discharged in time during the processing process, prevent interference with the mold and product, and ensure smooth production.

[0003] However, this utility model has the following problems when actually used:

[0004] When the existing punching and row hole mold for the bending machine is in use, a person manually holds the plate so that the bottom surface of the plate contacts the top surface of the lower mold. Then the machine is operated to move the upper cutting mold downward to drive the punching and row hole mold fixedly installed on its bottom surface. The bottom surface of the mold contacts the top surface of the plate. Then the punching and row hole mold extends and cooperates with the lower mold to squeeze the plate to form holes in the plate. Then the upper mold moves up and the plate is manually adjusted to move the plate to the next position. This reciprocating operation makes the machine produce a punching and row hole effect. However, in actual operation, the manual operation will deviate when the gap between the holes is made, which makes the emptying of the plate irregular and reduces the production quality.

[0026] The adjustment component includes an insert block 2, which is installed on one end surface of the stepper motor 108, a fixed plate 201 is installed on one side surface of the mold base 101, a first bearing 202 is installed on the inner wall of the fixed plate 201, an adjusting disc 203 is installed on the inner wall of the first bearing 202, a second bearing 204 is installed on the inner wall of the adjusting disc 203, an adjusting gear 205 is installed on the inner wall of the second bearing 204, a notch block 206 is installed on one end surface of the adjusting gear 205, and a feed gear 207 is installed on the outer surface of the adjusting gear 205.

[0027] One side surface of the insertion block 2 is fixedly connected to the output end of the stepper motor 108, one side surface of the fixed plate 201 is fixedly connected to one side surface of the mold base 101, the inner wall of the fixed plate 201 is fixedly connected to the outer side surface of the first bearing 202, and the inner wall of the first bearing 202 is fixedly connected to the outer side surface of the adjustment disc 203.

[0028] The inner wall of the adjusting disc 203 is installed with three second bearings 204 in a circular array. The outer surface of the second bearing 204 is fixedly connected to the inner wall of the adjusting disc 203. An adjusting gear 205 is installed on the inner wall of each second bearing 204.

At this time, enter the adjustment stage, manually rotate the adjustment disc 203, it will rotate smoothly with the support of the bearing, and drive the second bearing 204 on its inner wall and multiple adjustment gears 205 to rotate synchronously. Since the number of teeth of each adjustment gear 205 is different, according to the specific needs of punching holes, select the appropriate gear and rotate it to the same horizontal line as the insert block 2 to ensure that the notch block 206 is accurately aligned with the insert block 2. Example 2

[0030] Based on the above Example 1, please refer to Figure 5 - Figure 6 , including a discharging platform 3, which is installed on one side surface of the mold base 101, a discharging roller 301 is installed on the inner wall of the discharging platform 3, a discharging gear 302 is installed on a section of the surface of the discharging roller 301, an extension plate 303 is installed on one side surface of the discharging platform 3, a driving motor 304 is installed on the top surface of the extension plate 303, and a transmission chain 305 is installed on the outer surface of the discharging gear 302.

[0031] There are several discharging rollers 301, and the outer surfaces of the discharging rollers 301 are movably and rotatably connected to the inner wall of the discharging table 3. A discharging gear 302 is fixedly installed on one end surface of each discharging roller 301. The outer surfaces of several discharging gears 302 are engaged with a transmission chain 305, and the output end of the driving motor 304 is fixedly connected to one side surface of the discharging gear 302.

[0032] Start the electric slide 106, and the slider 107 drives the stepper motor 108 and the insert block 2 to move in the opposite direction until the insert block 2 is tightly plugged into the notch block 206, locking the spacing setting. Next, the plate to be processed is placed steadily between the adjusting rollers 104, and the stepper motor 108 is started. Through its rotation, it drives the insert block 2, the notch block 206 and the adjusting gear 205. This series of actions then drives the feed roller 103 and the adjusting roller 104 to work together, clamping the plate and moving it to the punching hole position according to the predetermined path. After the plate reaches the designated position, the upper mold 109 moves down quickly and cooperates closely with the mold base 101 to complete the punching hole operation. During the punching hole process, the plate moves regularly due to the precise engagement of the adjusting gear 205 and the feed gear 207, ensuring the processing quality. After the punching hole is completed, the plate enters the discharge table 3, and the drive motor 304 drives the discharge roller 301 to rotate through the discharge gear 302 and the chain transmission, and the processed plate is smoothly sent out of the punching area.

[0033] The working principle and usage process of this utility model are as follows: The mold base 101 and upper mold 109 are precisely installed on the upper and lower mold sections of the press brake platform 1, ensuring they are secure. Then, the electric slide 106 is activated, driving the slider 107 to move smoothly along the slide rails, simultaneously driving the top-mounted stepper motor 108 and the insert block 2 at the output end to gradually move forward. When the insert block 2 separates from the notch block 206 on the adjustment disk 203, the movement of the slider 107 stops.

[0034] At this point, the adjustment phase begins. Manually rotate the adjustment disc 203, which, supported by the bearings, rotates smoothly, driving the second bearing 204 on its inner wall and multiple adjustment gears 205 to rotate synchronously. Since each adjustment gear 205 has a different number of teeth, select the appropriate gear based on the specific needs of the punching hole and rotate it until it is aligned with the insert block 2, ensuring that the notch block 206 is precisely aligned with the insert block 2.

[0035] After the adjustment is completed, the electric slide 106 is restarted, and the slider 107 drives the stepper motor 108 and the insert block 2 to move in the opposite direction until the insert block 2 and the notch block 206 are tightly plugged together, locking the spacing setting. Next, the plate to be processed is placed steadily between the adjustment rollers 104, and the stepper motor 108 is started. Through its rotation, it drives the insert block 2, the notch block 206 and the adjustment gear 205. This series of actions then drives the feed rollers 103 and the adjustment rollers 104 to work together, clamping the plate and moving it along the predetermined path to the punching position.

[0036] After the sheet reaches the designated position, the upper die 109 rapidly descends, tightly engaging the die base 101 to complete the punching operation. During the punching process, the precise meshing of the adjustment gear 205 and the feed gear 207 ensures regular movement of the sheet, ensuring processing quality. After punching, the sheet enters the discharge station 3. The drive motor 304, through the discharge gear 302 and chain drive, rotates the discharge roller 301, smoothly transporting the finished sheet out of the punching area. This completes the entire punching process, including the adjustment, feeding, and discharge steps.
