Technical Field

[0001] This utility model relates to the technical field of bending machines, and in particular to a CNC hydraulic bending machine with a quick mold changing structure. Background Technology

[0002] A bending machine is a machine tool used in the metal processing field to bend metal sheets into workpieces with specific angles and shapes by applying pressure to cause plastic deformation. It is one of the core equipment for forming metal sheets. Bending machines can be divided into manual bending machines, hydraulic bending machines, and CNC bending machines. Bending machines achieve the bending and forming of sheet metal by moving the upper die (bending knife) and the lower die, and by combining the shapes of the upper and lower dies.

[0003] Currently, traditional CNC hydraulic bending machines are generally powered by hydraulic cylinders. The bending cutter is installed at the output end of the hydraulic cylinder by multiple bolts. When facing the production needs of multiple varieties and small batches, different bending cutters need to be changed for bending. At this time, the staff needs to manually disassemble and install bolts and other fasteners to replace and fix the bending cutter. However, this operation process is cumbersome, consumes a lot of manpower and time, and causes the equipment to be down for too long, which seriously affects the production efficiency. Utility Model Content

[0005] Therefore, one objective of this utility model is to propose a CNC hydraulic bending machine with a quick mold changing structure. By setting up an installation mechanism, the bending cutter can be quickly replaced and fixed, reducing equipment downtime, improving production efficiency, and making the bending cutter replacement process simpler and faster.

[0016] The embodiments of this utility model are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0017] The following describes an embodiment of the present invention, a CNC hydraulic bending machine with a quick mold changing structure, with reference to the accompanying drawings.

[0018] like Figures 1-4 As shown in the figure, a CNC hydraulic bending machine with a quick mold changing structure according to an embodiment of the present invention includes: a bending machine 1 and an installation mechanism 2.

[0019] The mounting mechanism 2 is located outside the bending machine 1. The mounting mechanism 2 includes a mounting base 21, a fixing plate 22, a positioning pin 23, and a locking assembly 3.

[0020] Mounting base 21 is installed on the inner wall of bending machine 1, fixing plate 22 is fixed on mounting base 21, positioning pin 23 is rotatably connected to the inner wall of fixing plate 22, and engaging assembly 3 is set inside mounting base 21.

[0021] The locking assembly 3 includes a locking plate 31, a spring 32, a locking block 33, and a bending blade 35.

[0022] The locking plate 31 is installed inside the mounting base 21, the spring 32 is installed on the outer wall of the locking plate 31, the locking block 33 is connected to the other end of the spring 32, the outer wall of the locking block 33 has a limit hole 34, and the bending knife 35 is installed on the bottom wall of the locking plate 31.

[0023] A limiting plate 24 is fitted on the outer wall of the positioning pin 23.

[0024] It should be noted that in this embodiment of the present invention, the limiting plate 24 is fixedly sleeved on the outer wall of the positioning pin 23. The limiting plate 24 restricts the length of the positioning pin used for positioning, so that when the positioning pin 23 is inserted into the limiting hole 34 on the outer wall of the card block 33, the limiting plate 24 abuts against the fixing plate 22.

[0025] Understandably, the function of the limiting plate 24 is to axially limit the positioning pin 23, preventing it from moving axially during operation and ensuring that the positioning pin 23 can be accurately inserted into the limiting hole 34 on the outer wall of the clamping block 33, thereby ensuring the stability and reliability of the folding bend 35. When the positioning pin 23 is inserted into the limiting hole 34, the limiting plate 24 contacts the outer wall of the mounting base 21, restricting the positioning pin 23 from moving further inward, thus avoiding damage to the clamping block 33 or affecting the normal operation of the clamping assembly 3 due to excessive insertion of the positioning pin 23; when it is necessary to remove the positioning pin 23, the limiting plate 24 also ensures that the positioning pin 23 will not be completely removed.

[0026] Specifically, when it is necessary to disassemble the bending blade 35, first pull the positioning pin 23 upwards, separating it upwards along the direction of the limiting hole 34. Then press the locking block 33, which compresses the spring 34. At this time, the spring 34 and the locking block 33 are housed inside the locking plate 31, thereby disengaging the locking plate 31 from the mounting base 21. In this way, the locking plate 31 can be removed from the inside of the mounting base 21, and then the bending blade 35 can be removed from the inside of the mounting base 21.

[0027] When a new bending blade 35 needs to be installed, first pull out the positioning pin 23 upwards, and then place the bending blade 35 at the corresponding position on the bottom wall of the locking plate 31. Next, push the locking plate 31 upwards. At this time, the locking block 33 contacts the mounting base 21, and the mounting base 21 squeezes the locking block 33, causing the locking block 33 to compress the spring 32 inwards. When the locking block 33 moves to the hole on the outer wall of the mounting base 21, the locking block 33 pops outwards under the elastic force of the spring 32 and locks into the hole on the outer wall of the mounting base 21, thus achieving initial fixation of the locking plate 31. At this time, release the suspended positioning pin 23, and the positioning pin 23 inserts downwards into the limiting hole 34 on the outer wall of the locking block 33 to further fix the bending blade 35, thereby completing the quick replacement of the bending blade 35.

[0028] In one embodiment of this application, such as Figure 3 As shown, the bending machine 1 is equipped with a feeding mechanism 4, which includes a power source 41, a connecting block 42, a fixing block 43, a driving component 44, and a feeding plate 45.

[0029] The power source 41 is installed on the outer wall of the bending machine 1. The connecting block 42 is connected to the output end of the power source 41. The fixing block 43 is fixed on the outer wall of the connecting block 42. The driving component 44 is installed inside the fixing block 43. The feeding plate 45 is connected to the rotating shaft of the driving component 44.

[0030] It should be noted that the power source 41 described in this embodiment of the present invention is preferably a cylinder, and the driving component 44 is preferably a drive motor.

[0031] Specifically, when workers need to bend the steel plate, the steel plate is first placed on the loading plate 45. Then, the power source 41 is started by an external device. The power source 41 drives the fixed block 43 to move outward through the connecting block 42, which in turn drives the drive component 44 and the loading plate 45 to move together. At this time, the worker places the steel plate on the loading plate 45, and the power source 41 retracts to transport the steel plate to the bending position of the bending machine 1. Then, the drive component 44 is started by an external device. The drive component 44 drives the loading plate 45 to rotate at a certain angle, so that the steel plate is at a suitable bending angle, which facilitates the subsequent bending operation of the bending blade 35 on the steel plate. This reduces the labor intensity of manual loading and improves the loading efficiency and accuracy.

[0032] In one embodiment of this application, such as Figure 4 As shown, the outer wall of the bending machine 1 is provided with a bending assembly 5, which includes a slide rail 51, a slider 52 and a bending groove plate 53.

[0033] The slide rail 51 is installed on the outer wall of the bending machine 1, the slider 52 is slidably connected to the outer wall of the slide rail 51, and the bending groove plate 53.

[0034] Specifically, when it is necessary to bend steel plates of different specifications, the workers can adjust the position of the bending groove plate 53 by sliding the slider 52 along the slide rail 51 according to the size of the steel plate and the bending requirements, so that it matches the steel plate to be bent.

[0035] In one embodiment of this application, such as Figure 1 As shown, the bending machine 1 is equipped with a conveying assembly 6, which includes a support plate 61 and a conveying shaft 62.

[0036] The support plate 61 is mounted on the bending machine 1, and the conveying shaft 62 is rotatably connected to the inner wall of the support plate 61.

[0037] Specifically, when the workers convey the steel plate for bending, the steel plate passes through the area of ​​the conveying component 6, and the conveying shaft 62 starts to rotate under the movement of the steel plate. Due to the friction between the conveying shaft 62 and the surface of the steel plate, the steel plate moves forward along the rotation direction of the conveying shaft 62 under the action of friction, thereby assisting the workers in conveying the steel plate, reducing the physical exertion of the workers when conveying the steel plate, and improving the stability and efficiency of the conveying.

[0038] Working principle: When the bending blade 35 needs to be disassembled, first pull the positioning pin 23 upward, separating it upward along the direction of the limiting hole 34. Then press the locking block 33, which compresses the spring 34. At this time, the spring 34 and the locking block 33 are housed inside the locking plate 31, thereby detaching the locking plate 31 from the mounting base 21. In this way, the bending blade 35 can be removed from the inside of the mounting base 21. When a new bending blade 35 needs to be installed, first pull the positioning pin 23 upward, and then place the bending blade 35 at the corresponding position on the bottom wall of the locking plate 31. Then push the locking plate 31 upward, at which time the locking block 33 contacts the mounting base 21. The mounting base 21 squeezes the locking block 33, causing the locking block 33 to compress the spring 32 and retract inward. When the locking block 33 moves to the hole on the outer wall of the mounting base 21, the locking block 33 pops outward under the elastic force of the spring 32 and locks into the hole on the outer wall of the mounting base 21, achieving initial fixation of the locking plate 31. At this point, the suspended positioning pin 23 is released, and the positioning pin 23 is inserted downwards into the limiting hole 34 on the outer wall of the clamping block 33 to further fix the bending blade 35, thereby completing the quick replacement of the bending blade 35. Next, the steel plate to be bent is placed on the loading plate 45, and the power source 41 is started. The power source 41 drives the connecting block 42, the fixing block 43, the driving component 44, and the loading plate 45 to move together, conveying the steel plate to the bending position of the bending machine 1. Then, according to the size of the steel plate and the bending requirements, the sliding slider 52 adjusts the position of the bending groove plate 53 to match the steel plate to be bent. After that, the driving component 44 is started, and the driving component 44 drives the loading plate 45 to rotate a certain angle, so that the steel plate is at a suitable bending angle. At this time, the hydraulic cylinder starts to work, applying pressure to the steel plate, causing it to undergo plastic deformation under the action of the bending blade 35 and the bending groove plate 53, completing the bending operation. During the steel plate conveying process, the conveying shaft 62 starts to rotate under the drive of the moving steel plate, assisting in the conveying of the steel plate and improving the stability and efficiency of the conveying.
