Description

Technical Field

[0001] This utility model relates to the field of pipe processing technology, specifically to an automatic loading and unloading pipe bending machine. Background Technology

[0002] Pipe bending machines are widely used in the construction industry, power construction, highway and railway construction, boilers, bridges, ships, furniture, decoration and other fields. In the current technology, the production of automated pipe bending machines involves stages such as loading, feeding, bending and unloading. The current loading device uses a suspended material hopper and a stepped loading method. During operation, this loading device is prone to problems such as material falling from the hopper to the ground or falling on the steps, causing material jamming. The unloading work is all done manually. After the pipe bending machine completes the bending of the pipe fitting, one employee is required to place the bent pipe fitting in the pipe fitting trolley. The employee frequently bends and turns, and the repetitive actions cause wasted time and effort. Moreover, the pipe fitting is prone to falling to the ground, which can easily cause deformation and scrap. Utility Model Content

[0006] According to one embodiment of the present invention, the feeding device includes a material receiving bin and a support, the support is disposed between the material trough and the bending pipe device, and the material receiving bin is fixed on the support.

[0007] According to one embodiment of the present invention, the feeding device further includes a storage box, which is disposed on one side of the receiving bin. The receiving bin is inclined downward along the positive Y-axis towards the storage box to form an opening, and the storage box is located at the opening.

[0008] According to one embodiment of the present invention, the feeding device further includes a support base, which is disposed between the material trough and the bending pipe assembly, and the bracket is fixed on the support base.

[0009] According to one embodiment of the present invention, the discharge bin further includes a second driving device, a rotating rod, and a gripper.

[0014] The beneficial effects of this utility model are as follows: Compared with the prior art, this automatic loading and unloading tube bending machine uses a feeding plate as a whole, so that the workpiece can be placed on the feeding plate as a whole without falling to the ground. Since the feeding plate is inclined downward along the positive Y-axis, the workpiece can automatically roll towards the baffle. A lifting plate is set between the baffle and the feeding plate. When the material rolls to the lifting plate, the first drive device is activated to make the lifting plate move along the Z-axis until it is flush with the top of the baffle. That is, the lifting plate can carry the workpiece on it to the top of the baffle. The discharge plate is connected to the top of the baffle and is inclined downward from the top along the positive Y-axis to the material trough, so that the workpiece rolls into the material trough along the inclined direction of the discharge plate. The pushing component pushes the workpiece in the material trough into the tube bending device. The tube bending device performs tube bending processing on the workpiece. After the workpiece is processed, it is unloaded into the unloading device located between the material trough and the tube bending device. The lifting plate transports workpieces one by one to the top of the baffle, preventing workpiece jamming and thus reducing production efficiency. The unloading device collects finished workpieces, eliminating the need for manual handling of each piece. Once a sufficient quantity of workpieces has been stored in the unloading device, they are all removed and sorted together. This reduces the labor intensity of workers and prevents workpieces from falling to the ground, causing deformation or scrap. The entire process is automated, thereby improving production efficiency.

[0033] Please see Figure 1 and Figure 2 As shown, Figure 1This is a schematic diagram of the automatic loading and unloading pipe bending machine in the embodiment. Figure 2 This is another schematic diagram of the automatic loading and unloading pipe bending machine in the embodiment. This embodiment discloses an automatic loading and unloading pipe bending machine, including a machine base 1, a loading device 2, a feeding device 3, a bending device 4, and an unloading device 5. The feeding device 3 is fixedly mounted on the machine base 1, the loading device 2 is fixed on the machine base 1 and located on one side of the feeding device 3, the bending device 4 is located on the other side of the loading device 2, and the unloading device 5 is located between the bending device 4 and the feeding device 3.

[0034] In practical applications, workpiece 7 is placed into the loading device 2, which then starts to load the workpiece 7 into the feeding device 3. The feeding device 3 pushes the workpiece 7 into the bending device 4, where it bends the workpiece 7. After bending, the workpiece 7 falls into the unloading device 5. The entire process is automated, improving production efficiency. The unloading device 5 eliminates the need for workers to immediately retrieve and organize each workpiece 7 after processing. Workpieces are only removed and organized once the unloading device 5 has stored a sufficient quantity, reducing labor intensity and preventing workpieces from falling to the ground and deforming or becoming unusable.

[0035] Please see Figure 3 and Figure 4 As shown, Figure 3 This is a schematic diagram of the feeding device in the embodiment. Figure 4 This is a cross-sectional view of the feeding device in the embodiment. In this embodiment, the feeding device 2 includes a frame 21, a feeding bin 22, a first driving device, a lifting plate 23, and a discharge plate 24. The frame 21 is mounted on the machine base 1, and the feeding bin 22 is mounted on the frame 1. The feeding bin 22 includes a baffle 221, two side plates 222, and a feeding plate 223. The feeding plate 223, which is inclined downward along the positive Y-axis, is arranged between the two side plates 222. The baffle 221 is arranged behind the inclined feeding plate 223, and the baffle 221 and the two side plates 222 are fixed on the same side of the feeding plate 223. That is, the baffle 221, the two side plates 222, and the feeding plate 223 form a feeding bin 22 for holding the workpiece 7. The first drive device is fixed on the frame 21. The lifting plate 23 is set at the junction of the baffle 221 and the discharge plate 223, and the lifting plate 23 is connected to the first drive device. Under the drive of the first drive device, the lifting plate 23 moves from the junction of the baffle 221 and the discharge plate 223 along the positive Z-axis to be flush with the top 2211 of the baffle 221. One end of the discharge plate 24 is connected to the top 2211, and the discharge plate 24 is inclined downward along the positive Y-axis.

[0036] Please see Figure 5 As shown, Figure 5This is a schematic diagram of the feeding device in the embodiment. In this embodiment, the feeding device 3 includes a pushing assembly 31 and a material trough 32. The material trough 32 is fixedly mounted on the machine base 1 and is connected to the end of the discharge plate 24. The pushing assembly 31 is located at one end of the material trough 32, and the material trough 32 is located in the pushing direction of the pushing assembly 31. The pushing assembly 31 can move relative to the machine base 1 along the X-axis. That is, when the workpiece 7 is fed into the material trough 32 by the feeding device 2, the pushing assembly 31 works, pushing the workpiece 7 in the material trough 32 to move along the positive X-axis, so that the workpiece 7 can enter the bending device 4. Figure 1 As shown, one end of the discharge plate 24 is connected to the top 2211, and the other end of the discharge plate 24 extends to the material trough 32. That is, the discharge plate 24 is inclined downward from the top 2211 along the positive Y-axis to the material trough 32.

[0037] Review Figure 1 As shown, in this embodiment, the bending device 4 is located at the end of the material trough 32 away from the pushing assembly 31, and the feeding end 41 of the bending device 4 is located in the pushing direction of the pushing assembly 31. That is, both the material trough 32 and the feeding end 41 of the bending device 4 are located in the pushing direction of the pushing assembly 31. When the pushing assembly 31 pushes the workpiece 7 in the material trough 32 along the pushing direction, the workpiece 7 can enter the feeding end 41 of the bending device 4, so that the bending device 4 can perform a bending operation on the workpiece 7. The unloading device 5 is arranged between the material trough 32 and the bending device 4. After the bending device 4 completes the bending, the workpiece falls into the unloading device 5.

[0038] In practical applications, a feeding bin 22 is formed by the baffle 221, two side plates 222, and feeding plate 223. The workpiece 7 to be processed is placed in the feeding plate 223, preventing it from falling to the ground. Because the feeding plate 223 is inclined downwards along the positive y-axis, the workpiece 7 in the feeding plate 223 automatically rolls towards the lifting plate 23 located between the baffle 221 and the feeding plate 223. When the workpiece 7 rolls to the lifting plate 23, the first drive device is activated, driving the lifting plate 23 to move up and down along the Z-axis. The workpiece 7 located on the lifting plate 23 is then transported to the junction of the top 2211 and the discharge plate 24. Since the discharge plate 24 is inclined downward from the top 2211 along the positive y-axis to the material trough 32, the workpiece 7 rolls into the material trough 32 through the discharge plate 24. The pusher assembly 33 pushes the workpiece 7 in the material trough 32 in the positive x-axis direction until the workpiece 7 reaches the feed end 41 of the bending device 4 and enters the bending device 4. The bending device 4 performs bending processing on the workpiece 7. After processing, the workpiece is discharged into the unloading device 5 located between the material trough 32 and the bending device 4. This design uses the lifting plate 23 to transport the workpiece 7 to the top 2211 of the baffle 221 one by one, without causing the workpiece 7 to jam and affect production efficiency. The unloading device 5 can collect the processed workpiece 7, eliminating the need for workers to immediately pick up and put away each workpiece 7 after processing. Workers only need to wait for the unloading device 5 to store a certain number of workpieces 7 before taking them out and sorting them together. This reduces the labor intensity of workers and prevents the workpiece 7 from falling to the ground and causing deformation or scrap. The whole process is automated, thereby improving production efficiency.

[0039] Specifically, the first drive device uses a cylinder, which has high working accuracy and environmental adaptability, and can stably output instantaneous pressure and flow to ensure the stable operation of mechanical equipment. Moreover, the cylinder has a relatively simple structure, which reduces the cost of maintenance and replacement.

[0040] Specifically, a first angle ∠1 is formed between the feeding plate 223 and the baffle 221, with the first angle ∠1 ranging from 68 degrees to 72 degrees. This allows the workpiece 7 to automatically roll to the lifting plate 23 located between the feeding plate 223 and the baffle 221 when placed on the feeding plate 223, eliminating the need for manual pushing of the workpiece 7. The workpiece 7 can be automatically rolled to the lifting plate 23, enabling continuous conveying of the workpiece 7 and reducing the labor intensity of workers.

[0041] Specifically, a second included angle ∠2 is formed between the discharge plate 24 and the baffle 221, and the range of the second angle ∠2 is 68 degrees to 72 degrees. This allows the workpiece 7 to automatically roll into the material trough 32 along the inclined direction of the discharge plate 24 when it is transported to the discharge plate 24, so that the workpiece 7 will not be stuck on the discharge plate 24 and thus the supply of workpiece 7 will not be delayed.

[0042] Please review further. Figure 1 and see Figure 6 As shown, Figure 6 This is a schematic diagram of the pipe bending device in the embodiment. In this embodiment, the pipe bending device 4 includes a fixed base 42, a pipe bending assembly 43, and a CNC machine tool. The fixed base 42 is located at the end of the material trough 32 away from the pushing assembly 31. The pipe bending assembly 43 is mounted on the fixed base 42. The CNC machine tool is electrically connected to the pipe bending assembly 43, and the pipe bending assembly 43 is collinear with the material trough 32, that is, the pipe bending assembly 43, the material trough 32, and the pushing assembly 31 are on the same axis. The unloading device 5 is placed directly below the pipe bending assembly 43. The pushing assembly 31 pushes the workpiece 7 located in the material trough 32 toward the pipe bending assembly 43 until the workpiece 7 moves into the pipe bending assembly 43. The CNC machine tool then starts and controls the pipe bending assembly 43 to perform pipe bending processing on the workpiece 7. After processing, the workpiece 7 is unloaded into the unloading device 5 located below the pipe bending assembly 43. This design is simple to operate, automates processing and unloading, and improves production efficiency.

[0043] Further, please refer to Figure 7 As shown, Figure 7 This is a schematic diagram of the feeding device in the embodiment. In this embodiment, the feeding device 5 includes a material receiving bin 51 and a support 52. The material receiving bin 51 is disposed on the support 52, and the support 52 is located between the material trough 32 and the bending device 4.

[0044] Further, please refer to Figure 8 As shown, Figure 8 This is a cross-sectional view of the feeding device in the embodiment. In this embodiment, the feeding device 5 also includes a storage bin 53, which is placed on one side of the receiving bin 51. The receiving bin 51 is inclined downward along the positive Y-axis to form an opening 511, and the storage bin 53 is located at the opening 511 of the receiving bin 51. Specifically, the receiving bin 51 and the support 52 form a third angle ∠3, which ranges from 68 degrees to 72 degrees. This allows the workpiece 7 to automatically roll along the inclined direction of the receiving bin 51 into the storage bin 53 located at the opening 511, preventing the workpiece 7 from being stuck in the receiving bin 51 and requiring manual pushing, thus reducing the labor intensity of workers.

[0045] Furthermore, review Figure 7 As shown, in this embodiment, the feeding device 5 also includes a support base 54, which is located between the machine base 1 and the fixed base 42, and the bracket 52 is mounted on the support base 54. Specifically, the support base 54 increases the stability and load-bearing capacity of the structure. In addition, the support base 54 can also balance the structure by adjusting its height, thickness, width and other parameters to ensure the stable operation of the automatic feeding and unloading pipe bending machine.

[0046] Furthermore, review Figure 4As shown, in this embodiment, the discharge bin 22 further includes a second drive device, a rotating rod 224, and a gripper 225. The second drive device is mounted on the frame 21 and connected to the rotating rod 224. The gripper 225 is fixedly mounted on the rotating rod 224. The two ends of the rotating rod 224 are rotatably mounted on two side plates 222, and the gripper 225 rests on the discharge plate 24. There is a distance of the diameter of a workpiece 7 between the gripper 225 and the baffle 221. Specifically, the second drive device is a cylinder. Cylinders have high working accuracy and environmental adaptability, and can stably output instantaneous pressure and flow, ensuring the stable operation of the mechanical equipment. Moreover, the structure of the cylinder is relatively simple, reducing the cost of maintenance and replacement.

[0047] In practical applications, workpiece 7 is placed on the feeding plate 223. Due to the tilt angle of the feeding plate 223, workpiece 7 automatically rolls to the lifting plate 23. The first drive device is activated to drive the lifting plate 23 to move along the Z-axis, thereby transporting workpiece 7 to the connection between the top 2211 of the baffle 221 and the discharge plate 24. Since the gripper 225 is mounted on the discharge plate 24, the gripper 225 controls workpiece 7 on the discharge plate 24. Then, the second drive device is activated to drive the rotating rod 224 to rotate. The rotating rod 224 rotates at the same time, causing the gripper 225 to rotate, so that the gripper 225 moves away from the discharge plate 24. That is, workpiece 7 is no longer controlled by the gripper 225 and rolls along the discharge plate 24 into the material trough 32. This controls that only one workpiece 7 is fed into the material trough 32 each time, and will not cause jamming due to multiple workpieces 7 entering the material trough 32 at the same time, thus affecting the operation of the feeding device 3.

[0048] Furthermore, in this embodiment, the feeding device 2 also includes a screw drive mechanism 25. The screw drive mechanism 25 includes a control component 251, a screw 252, a partition plate 253, and a nut 254. The control component 251 is disposed at one end of the screw 252. The partition plate 253 is fixedly connected to the nut 254. The other end of the screw 252 passes through one side plate 222, and then sequentially passes through the nut 254 and the other side plate 222. That is, the partition plate 253 and the nut 254 are located between the two side plates 222. The two side plates 222 are rotatably connected to the screw 252. When the screw is rotated by the control component 251, the nut 254 moves back and forth along the X-axis of the screw 252. One end of the rotating rod 224 is rotatably connected to one of the side plates 222, and the other end passes through the isolation plate 253 and is rotatably connected to the other side plate 222. The isolation plate 253 is movably connected to the rotating rod 224, and the gripper 225 is located between the isolation plate 253 and one of the side plates 222.

[0049] Through the design of the screw transmission mechanism 25, the rotation control component 251 controls the screw 252 to rotate. The rotation of the screw 252 simultaneously drives the isolation plate 253, which is fixed to the nut 254, to move along the X-axis, thereby adjusting the distance between the isolation plate 253 and the side plate 222, that is, adjusting the width of the feeding plate 223 that can hold the workpiece 7. When the length and size of the workpiece 7 are different, it can be adjusted according to actual needs, eliminating the need to purchase multiple feeding devices 2 of different specifications, thereby reducing equipment costs.

[0050] Furthermore, in this embodiment, the feeding device 2 also includes two baffle blocks 26, which are symmetrically arranged on the opposite side of the isolation plate 253 and the side plate 222. The gripper 225 is located between the isolation plate 253 and the side plate 222 where the baffle blocks 26 are located. There is a height difference between the end of the baffle block 26 near the discharge plate 223 and the discharge plate 223. By setting the baffle blocks 26, when multiple workpieces 7 are placed on the discharge plate 223 at one time, not all workpieces 7 will roll to the lifting plate 23, which would put a lot of pressure on the lifting plate 23, thus affecting the normal lifting and lowering activities of the lifting plate 23. It is also easy for workpieces 7 to accumulate too high, which would compress the operation of the lifting plate 23. The height difference between the end of the baffle block 26 near the discharge plate 223 and the discharge plate 223 can be set according to actual needs. The baffle blocks 26 intercept workpieces 7 exceeding a certain amount, thereby controlling the number of workpieces 7 flowing to the baffle 221 at the same time.

[0051] Furthermore, in this embodiment, the feeding bin 22 also includes a feeding gate 2221, which is rotatably mounted on a side plate 222 near the gripper 225, meaning the feeding gate 2221 can rotate circumferentially relative to the side plate 222. With the feeding gate 2221, when the workpiece 7 is very small, the width of the feeding plate 223 is very small, meaning the distance between the two side plates 222 is very small. When manually placing the workpiece 7, the hand is larger than the distance between the two side plates 222, making it difficult to reach into the feeding bin 22 to place the workpiece 7. The feeding gate 2221 can be opened when needed, facilitating the placement of the workpiece 7.

[0052] Furthermore, review Figure 2 As shown, in this embodiment, the automatic loading and unloading pipe bending machine also includes a fence 6, which is arranged around the side of the storage box 53 away from the receiving bin 51. By setting up the fence 6, it is possible to prevent workers from being accidentally injured when they go over to check the loading situation because they are too close to the automatic loading and unloading pipe bending machine, thus protecting the personal safety of the workers.

[0053] In the actual process, before placing the workpiece 7 to be processed onto the feeding plate 223, the worker first controls the screw 252 to rotate by rotating the control component 251. The rotation of the screw 252 simultaneously drives the isolation plate 253, which is fixed to the nut 254, to move along the X-axis, thereby adjusting the distance between the isolation plate 253 and the side plate 222, that is, adjusting the feeding plate 223 to just the width to place the workpiece 7. When the width of the feeding plate 223 that can hold the workpiece 7 is very small, the feeding gate 2221 can be opened to make it convenient for the worker to reach out and place the workpiece 7 into the feeding plate 223. Because the feeding plate 223 is inclined downward along the positive Y-axis, the workpiece 7 rolls towards the baffle 221 until it reaches the lifting plate 23. The first drive device then activates and drives the lifting plate 23 to move up and down along the Z-axis, thereby moving the workpiece 7 on the lifting plate 23 to the connection point between the top 2211 of the baffle 221 and the discharge plate 24. Since the discharge plate 24 is inclined downward from the top 2211 along the positive Y-axis to the material trough 32, the workpiece 7 will roll along the inclination direction of the discharge plate 24 to... In the material trough 32, the gripper 225 is set up to control the workpiece 7 to temporarily stay on the discharge plate 24. The second drive device drives the rotating rod 224 to rotate, and the rotating rod 224 rotates and drives the gripper 225 to rotate, so that the gripper 225 rotates away from the discharge plate 24, and the workpiece 7 controlled by the gripper 225 is released from control and rolls along the inclined direction of the discharge plate 25 into the material trough 32. This controls the workpiece 7 to flow into the material trough 32 one by one, and prevents the material trough 32 from getting stuck. The pusher assembly 31 is activated and pushes the workpiece 7 located in the trough 32 toward the bending assembly 43 until it reaches the bending assembly 43. The CNC machine tool controls the bending assembly 43 to bend the workpiece 7. After processing, the workpiece 7 falls into the receiving bin 51. Since the receiving bin 51 is tilted downwards along the positive Y-axis toward the storage box 53, the workpiece 7 automatically slides down along the tilt direction of the receiving bin 51 until it enters the storage box 53 from the outlet 521. This design eliminates the need for workers to immediately retrieve and put away each workpiece 7 after processing. They only need to wait until the storage box 53 has stored a certain number of workpieces 7 before taking them out and putting them away together. This reduces the labor intensity of workers and prevents the workpieces 7 from falling to the ground and causing deformation or scrap. The fence 6 allows workers to easily observe the unloading situation from outside the fence 6, preventing them from being accidentally injured by being too close to the automatic loading and unloading bending machine, thus protecting the personal safety of the workers.
