Description

Technical Field

[0001] The utility model relates to a cold bending forming production line, in particular to a quick-change roller pressing main machine type cold bending forming production line. Background Art

[0002] In the actual production of traditional cold-bending forming production lines, if the production specifications need to be changed, the traditional way is to manually replace the mold roller after the production line is shut down, and then start the machine after adjustment. Since manually replacing the roller mold of the entire line is labor-intensive, the re-adjustment time is long, time-consuming, labor-intensive and inefficient. In order to solve this problem, a variety of roller main machines of different specifications have appeared in the prior art. The roller main machine is a modular product, which is fixed to the bottom machine base by bolts. When the production specifications need to be changed, multiple roller main machines of the same model can be directly replaced one by one, and then the roller main machine is connected to the power to form a roller production line of new specifications.

[0003] The replacement method of the roller main machine is: first, remove the bolts between the roller main machine and the bottom machine base, then connect the roller main machine to the crane for lifting, move it to other areas, and then connect the roller main machine to be replaced to the crane, move it to the top of the bottom machine base, and slowly drop it to the bottom machine base. During the descent, multiple workers repeatedly adjust the position of the roller main machine to ensure that the front and rear directions and the left and right directions are accurate. Due to the heavy weight of the roller main machine, its positioning is more difficult, and multiple workers are required to assist in positioning in the front, rear, left and right directions at the same time. Many workers are required and the positioning time is long. After the positioning is completed, the roller main machine needs to be fixed to the bottom machine base by bolts, which is inefficient. After the roller main machine is replaced, the power end of the power mechanism needs to be connected to the input end on the roller main machine. Bolts are mainly used to fix to achieve power docking in the prior art. This fixing method has low operating efficiency and high labor intensity. Utility Model Content

When the positioning wear blocks 600 are worn out after multiple replacements, they can be removed and replaced to avoid affecting the positioning accuracy of the roller pressing main machine 200.

[0050] See also Fig. 9The power quick-connect device 500 includes a left half clutch 510 and a right half clutch 520 which are coaxially arranged on the left and right sides. The left half clutch 510 and the right half clutch 520 are engaged with each other by tooth engagement. The right half clutch 520 is fixedly mounted on the power input shaft of the rolling main machine 200. The left half clutch 510 is mounted on the power output shaft of the power mechanism 300. The power mechanism 300 is provided with a docking drive device 530 which cooperates with the left half clutch 510. The docking drive device 530 drives the left half clutch 510 to slide along the axis of the power output shaft to engage or disengage the right half clutch 520. The left half clutch 510 and the right half clutch 520 are connected by tooth engagement, which belongs to the prior art and will not be described here. The left half clutch 510 is connected to the power output shaft by a key, and the left half clutch 510 can slide horizontally along the key.

[0051] See also Fig.10 and Fig.11 The docking drive device 530 includes a mounting support 531 and a docking drive cylinder 532, the cylinder body of the docking drive cylinder 532 is hinged on the mounting support 531, the telescopic end of the docking drive cylinder 532 is hinged with a docking swing arm 533, the middle part of the docking swing arm 533 is hinged on the mounting support 531, the bottom end of the docking swing arm 533 is provided with a docking plug arm 534, the surface of the left half clutch 510 is provided with a docking ring groove 535, and the end of the docking plug arm 534 is correspondingly inserted into the docking ring groove 535.

[0053] See also Fig.13 and Fig.14 The mounting support 531 is provided with an articulated seat which is articulated with the docking swing arm 533 .

[0054] See also Fig.15The power mechanism 300 is provided with a distance sensor 701, the outer peripheral surface of the right half clutch 520 is provided with a positioning block 702 corresponding to the distance sensor 701, the outer peripheral surface of the left half clutch 510 is provided with a shielding ring plate 703, the surface of the shielding ring plate 703 is provided with a light-transmitting hole 704, the light-transmitting hole 704 is located between the distance sensor 701 and the positioning block 702, and the signal of the distance sensor 701 can reach the surface of the positioning block 702 through the light-transmitting hole 704. When the left half clutch 510 and the right half clutch 520 are in the engaged state, the light-transmitting hole 704 corresponds to the position of the positioning block 702. When the signal of the distance sensor 701 passes through the light-transmitting hole 704 but does not reach the positioning block 702, it means that the position of the right half clutch 520 does not correspond to the position of the left half clutch 510. The distance sensor 701 detects the distance between the positioning block 702 and transmits the distance signal to the controller, and determines whether the position of the positioning block 702 corresponds according to the distance value.

[0055] The working principle of this embodiment is:

[0056] First, unlock the current roller pressing host 200. The specific operation is as follows:

[0057] Step 1: The power mechanism 300 stops, and the left clutch 510 and the right clutch 520 stop. When the power mechanism 300 stops, the signal of the distance sensor 701 just reaches the positioning block 702 through the light-transmitting hole 704. At this time, the positions of the left clutch 510 and the right clutch 520 are defined as the docking position; then the docking drive cylinder 532 extends, driving the docking swing arm 533 to swing, and the docking pin 536 drives the left clutch 510 to slide horizontally in a direction away from the right clutch 520, so that the left clutch 510 is disengaged from the right clutch 520;

[0058] Step 2: The telescopic end of the sliding drive cylinder 451 is extended, and the sliding positioning pull plate 452 slides to the right, and the top end abuts against the push-pull protrusion 454 of the block on the right. As the sliding drive cylinder 451 continues to extend, the roller pressing main machine 200 is pushed to move to the right. At this time, the left side of the roller pressing main machine 200 is released from the left anti-slip groove 442. At this time, the locking anti-slip of the roller pressing main machine 200 is released, and it is separated from the bottom machine base 100. Then, the lifting buckle on the crane is connected to the roller pressing main machine 200 through the lifting eye screw, and the roller pressing main machine 200 is lifted and moved to other areas.

[0059] Step 3: Connect the next roller pressing main machine 200 to be replaced to the crane, move it to the top of the bottom machine base 100, and slowly lower it downward. Only one worker is required to operate during the lowering process. The worker first adjusts it in the front and rear directions so that the roller pressing main machine 200 slides down along the front guide inclined surface 412 or the rear guide inclined surface 422. At this time, the roller pressing main machine 200 can quickly enter between the front positioning block 411 and the rear positioning block 421. In this process, the V-shaped groove 463 and the V-shaped protrusion 464 also play an auxiliary positioning role; at the same time, the worker also adjusts the left and right directions so that the roller pressing main machine 200 slides down along the right guide inclined surface 432. The roller pressing main machine 200 falls After entering the bottom machine base 100, the sliding positioning pull plate 452 is located between the left and right block push-pull protrusions 454, and then the telescopic end of the sliding drive cylinder 451 retracts and contacts with the left block push-pull protrusion 454, pulling the roller pressing main machine 200 to move to the left as a whole until the left end of the roller pressing main machine 200 abuts against the left positioning block 441. At this time, the pull plate anti-slip protrusion 455 and the block anti-slip groove 456 are engaged, and the bottom end of the roller pressing main machine 200 extends into the left anti-slip groove 442 for engagement, and the sliding drive cylinder 451 is locked and fixed in this position, and the positioning and fixing are completed in the front and back, left and right, and up and down. Finally, the connection between the crane and the roller pressing main machine 200 is released;

[0060] Step 4: The angle of the replaced right half clutch 520 will not change, and it just corresponds to the docking position of the left half clutch 510, that is, the distance sensor 701 just reaches the positioning block 702 through the light-transmitting hole 704, and the automatic docking is directly started at this time, and the docking drive cylinder 532 is directly retracted, driving the docking swing arm 533 to swing, and the docking pin 536 drives the left half clutch 510 to slide toward the right half clutch 520, so that the left half clutch 510 and the right half clutch 520 are docked and engaged, that is, the power quick connection device 500 is automatically completed, and the docking drive cylinder 532 is locked in this position, which can ensure that the left half clutch 510 does not deviate from the position, and the dynamic After the force is started, the left clutch 510 and the right clutch 520 rotate to realize the transmission of power. When the left clutch 510 rotates, the rotating bearing 537 can rotate adaptively to reduce the friction between the two and limit the left clutch 510. However, if the angle of the right clutch 520 changes, the distance sensor 701 will not detect the positioning block 702 through the light-transmitting hole 704. Therefore, before docking, the worker needs to manually rotate the right clutch 520 and adjust the position of the positioning block 702 to correspond to the distance sensor 701. When the distance sensor 701 detects the positioning block 702, the automatic docking program is started.

[0061] Step 5: Multiple roller pressing main machines 200 are replaced one by one in this way. Since the position of each roller pressing main machine 200 is accurate, the positions between the multiple roller pressing main machines 200 are accurate. After all are replaced, a complete roller pressing production line can be formed. It can be used after the power is connected, which shortens the equipment debugging time.

[0062] The utility model adopts the front and rear positioning devices and the left and right positioning devices in conjunction with the crane, which can quickly realize the front and rear and left and right positioning of the roller pressing main machine 200. At the same time, the sliding anti-slip device 450 is used to realize the locking and anti-slipping of the roller pressing main machine 200 in the up and down directions, replacing the traditional screw fixing method to achieve screw-free quick installation. It is simple to replace, easy to operate, reduces the number of workers, and has a high replacement efficiency.

[0063] The utility model can be applied to the power quick-connect device 500 after the roller pressing main machine 200 is replaced. It is realized by tooth fitting, and the clutch is docked and locked by sliding, and it is no longer necessary to fix it by bolts. The docking method is simple and the effect is higher.
