Description

Technical Field

[0001] The present invention relates to the technical field of pipe processing equipment, and in particular to a pipe bending machine and a use method thereof. Background Art

[0002] In the field of pipe processing, pipe bending is an extremely critical process, which is widely used in many industries such as construction, automobile manufacturing and furniture production. With the rapid development of various industries, the demand for pipe bending is increasing, and higher requirements are placed on bending quality, precision and efficiency. At present, some pipe processing enterprises still use manual pipe bending, which is heavily dependent on the experience and skill level of the operator. The techniques and strength of different operators vary, resulting in uneven quality of pipe bending. In addition, manual operation cannot guarantee that the angle and curvature of each pipe bend are completely consistent. The size and shape accuracy of the pipe are difficult to guarantee, the product quality is unstable, and the scrap rate is high. This is a serious problem for modern manufacturing industries that pursue high quality. At the same time, manual pipe bending is inefficient, and workers are prone to fatigue due to long-term repetitive high-intensity labor, which further affects work efficiency and pipe bending quality, making it difficult to meet the needs of large-scale production. In addition, most existing pipe bending operations do not have automatic loading functions. Before each pipe bending, the pipe needs to be manually transported to the pipe bending equipment and positioned and installed. This process not only consumes a lot of manpower, but also has limited accuracy in manual positioning, which can easily cause the pipe to shift during the pipe bending process, affecting the bending accuracy. At the same time, the manual loading speed is slow and the process connection is not smooth, making the entire pipe bending production process inefficient and increasing time costs; Existing pipe bending equipment also has defects in structural design. Some pipe bending machines have complex structures and are composed of a large number of precise and complicated parts, which not only increases the manufacturing cost of the equipment, but also greatly increases the difficulty of daily maintenance and troubleshooting. In addition, most pipe bending machines can only process pipes of specific specifications and materials. When processing pipes of different diameters, wall thicknesses or materials, it is often necessary to replace the entire equipment or carry out large-scale modifications, which seriously limits the flexibility and diversity of production and cannot adapt to the rapidly changing market demands.

[0003] To sum up, it is urgent to develop a pipe bending machine that can automatically load, is easy to operate, has high bending accuracy, strong versatility and can reduce manual intervention. This is of great significance to promoting the development of the pipe processing industry. It can not only improve production efficiency and reduce costs, but also significantly improve product quality. Summary of the invention

[0014] How to use the pipe bending machine: select and replace the appropriate pipe limit assembly, reinforcement plate, tightening part and limit head according to the size of the pipe to be bent; Place the pipes to be bent on the storage table. At this time, the pipes close to the rotating part will be located between the two unloading guide plates and contact the arc surface of the rotating part. When loading is required, start the unloading motor to drive the rotating part to rotate. When the unloading port rotates to the two unloading guide plates, the pipes originally limited by the arc surface lose their constraints and slide obliquely downward under the action of gravity and fall into the unloading port. Then the unloading motor continues to drive the rotating part to flip, and the arc surface will limit the pipes newly entering between the unloading guide plates. At the same time, the pipes at the unloading port fall on the receiving table as the rotating part rotates, and the limiting columns set on the receiving table can effectively block the pipes and prevent them from falling. The pipe positioning operation starts the feeding motor, which drives the gear to rotate. The rotation of the gear drives the meshing rack to move toward the pipe. The push rod of the feeding cover extends from the inner end of the rack and moves forward with the movement of the rack. The push head on the push rod pushes the pipe until one end of the pipe is sleeved on the limit head. At this time, the pipe is just located between the pipe limit assembly and the abutment part, completing the positioning; The pipe limit adjustment is to start the first linear drive unit to push the clamping platform to move in the direction of the rotating mechanism, and the clamping part inside the clamping platform moves accordingly, cooperating with the pipe limit assembly to initially limit the pipe, and then start the hydraulic cylinder, the output end of the hydraulic cylinder pushes the displacement seat upward, and the roller on the displacement seat moves in the guide port of the connector, so that the bending seat moves in the direction of the straight extension section, and cooperates with the straight extension section to limit the pipe; To bend and unload the pipe, start the rotating motor, which drives the bending disk to rotate. When the bending disk rotates, it will also drive the drive box, bending seat and receiving table connected to it to rotate. At the same time, start the second linear drive unit, which pushes the arc groove to move toward the storage mechanism. Under the joint action of the rotating force and the thrust, the pipe is bent. In the process of the pipe limit assembly following the rotation of the bending disk, the arc reinforcement plate remains fixed. After the pipe is bent, the operator can remove the bent pipe to complete the entire pipe bending process.

[0015] The beneficial effects of the present invention are: High degree of automation, improved production efficiency: The pipe bending machine of the present invention has an automatic loading function. Through the coordinated operation of the storage and placement mechanism, the unloading motor, the loading mechanism and other components, the automatic process of pipe storage, unloading and loading is realized. Compared with traditional manual loading, it greatly saves manpower and time costs, improves production efficiency, and workers do not need to frequently carry and position pipes, reducing labor intensity. At the same time, the equipment can operate continuously and stably, and the process connection is smoother, which greatly improves the overall production efficiency. Precise positioning and high bending accuracy: During the pipe positioning and bending process, a variety of limiter components and adjustable structures ensure the precise positioning and stable bending of the pipe. The corresponding limiter components, reinforcing plates, clamping parts and limiter heads are replaced according to the pipe size, which can accurately adapt to pipes of different specifications. The clamping mechanism and the pipe limiter components work closely together to firmly limit the pipe before bending. In the bending process, the arc-shaped reinforcing plate enhances the stability of the pipe, so that the pipe can be accurately bent under the action of rotation and thrust, effectively improving the size accuracy and shape accuracy of the bent pipe and reducing the scrap rate. Reasonable structural design, easy adjustment and maintenance: The structural design of each component of the pipe bending machine is ingenious and reasonable, and the rotating mechanism, tightening mechanism, integrated storage mechanism and feeding mechanism are compactly arranged and work together. For example, the positioning seat on the rotating power box cooperates with the adjustment limit seat through the slide groove and the adjustment screw hole, which is convenient for adjustment according to parameters such as the length of the pipe; the hydraulic cylinder, connector and roller structures in the drive box can flexibly adjust the position of the bending seat to meet different bending requirements. This modular and adjustable design not only facilitates the operation and use of the equipment, but also makes it easy to disassemble and replace parts during equipment maintenance and troubleshooting, reducing the difficulty and cost of maintenance; Strong versatility and wide range of applications: By replacing different pipe limit assemblies, reinforcement plates, tightening parts and limit heads, the pipe bending machine can adapt to the processing of pipes of various diameters, wall thicknesses and materials. Whether it is a thin-walled aluminum pipe or a thick-walled steel pipe, precise bending operations can be performed on the equipment, breaking through the limitation that traditional pipe bending machines can only process pipes of specific specifications and materials. It has the beneficial effects of improving the versatility of the equipment and the flexibility of production, and meets the diverse market needs. BRIEF DESCRIPTION OF THE DRAWINGS

[0048] Method for using a pipe bending machine 1. Preliminary preparation: According to the size specifications of the pipe to be bent, select and replace the corresponding pipe limit assembly 9, reinforcement plate 56, tightening part 69 and limit head 53 to ensure that the equipment can accurately match the processing requirements of the pipe and lay the foundation for subsequent precise pipe bending operations.

[0049] 2. Automatic loading process: Place the pipes to be bent on the storage platform 72. At this time, the pipes close to the rotating member 79 will be located between the two unloading guide plates 78 and contact the curved surface 80 of the rotating member 79. When loading is required, start the unloading motor 82 to drive the rotating member 79 to rotate. When the unloading port 81 rotates to the two unloading guide plates 78, the pipes originally limited by the curved surface 80 lose their constraints and slide obliquely downward under the action of gravity and fall into the unloading port 81. Then, the unloading motor 82 continues to drive the rotating member 79 to flip, and the curved surface 80 will limit the pipes newly entering between the unloading guide plates 78. At the same time, the pipes at the unloading port 81 fall on the receiving platform 13 as the rotating member 79 rotates, and the limiting column 20 set on the receiving platform 13 can effectively block the pipes and prevent them from falling.

[0050] 3. Pipe positioning operation: Start the feeding motor, which drives the gear 88 to rotate. The rotation of the gear 88 drives the meshing rack 87 to move toward the pipe. The push rod 89 of the feeding cover 86 extends from the inner end of the rack 87, and moves forward with the movement of the rack 87. The push head 91 on the push rod 89 pushes the pipe until one end of the pipe is sleeved on the limit head 53. At this time, the pipe is just located between the pipe limit assembly 9 and the tight part 69, completing the precise positioning.

[0051] 4. Pipe limit adjustment: Start the first linear drive unit 62 to push the clamping platform 61 to move toward the rotating mechanism 1, and the clamping part 69 on the inner side of the clamping platform 61 moves accordingly, and cooperates with the pipe limit assembly 9 to preliminarily limit the pipe. Subsequently, start the hydraulic cylinder 36, and the output end of the hydraulic cylinder 36 pushes the displacement seat 33 upward. The roller 31 on the displacement seat 33 moves in the guide opening 30 of the connecting member 29, so that the bending seat 11 moves slightly toward the direction of the straight extension section 16, and further cooperates with the straight extension section 16 to limit the pipe. In the process of the roller 31 moving upward along the guide opening 30, the connecting member 29 will not move up and down, but will produce left and right displacement. Therefore, in actual operation, the height of the support block 32 needs to be set according to demand to ensure that when the roller 31 moves upward, the displacement seat 33 will not contact the lower end of the connecting member 29 to avoid limiting the normal movement of the roller 31.

[0052] 5. Pipe bending and unloading: Start the rotating motor, which drives the bending disk 7 to rotate. When the bending disk 7 rotates, it will also drive the drive box 23, the bending seat 11 and the receiving platform 13 connected thereto to rotate together. At the same time, start the second linear drive unit 63, which pushes the arc groove 66 to move toward the storage mechanism 3. Under the joint action of the rotating force and the thrust, the pipe is bent. In the process of the pipe limit assembly 9 rotating with the bending disk 7, the arc reinforcing plate 56 remains fixed, and its function is to enhance the stability of the pipe when it is bent. After the pipe is bent, the operator can remove the bent pipe to complete the entire pipe bending process.

It should be understood that a person skilled in the art can make many modifications and changes based on the concept of the present invention without creative work. Therefore, any technical solution that can be obtained by a person skilled in the art through logical analysis, reasoning or limited experiments based on the concept of the present invention on the basis of the prior art should be within the scope of protection determined by the claims.

10. A method for using the pipe bender as claimed in claim 9, characterized in that: According to the size specifications of the pipe to be bent, select and replace the pipe limiting assembly (9), reinforcing plate (56), abutting portion (69) and limiting head (53) that are suitable therefor; The pipe to be bent is placed on the storage table (72). At this time, the pipe close to the rotating member (79) is located between the two unloading guide plates (78) and contacts the arc surface (80) of the rotating member (79). When loading is required, the unloading motor (82) is started to drive the rotating member (79) to rotate. When the unloading port (81) rotates to the two unloading guide plates (78), the pipe originally limited by the arc surface (80) loses its constraint and is unloaded under the action of gravity. The pipe slides downward and falls into the discharge port (81), and then the discharge motor (82) continues to drive the rotating member (79) to flip, and the arc surface (80) limits the pipe newly entering between the discharge guide plates (78). At the same time, the pipe located at the discharge port (81) falls on the receiving platform (13) as the rotating member (79) rotates, and the limiting column (20) provided on the receiving platform (13) can effectively block the pipe and prevent it from falling. The pipe positioning operation starts the feeding motor, which drives the gear (88) to rotate. The rotation of the gear (88) drives the rack (87) meshing therewith to move toward the pipe. The push rod (89) extending from the inner end of the rack (87) of the feeding cover (86) moves forward with the movement of the rack (87). The push head (91) on the push rod (89) pushes the pipe until one end of the pipe is sleeved on the limit head (53). At this time, the pipe is exactly located between the pipe limit assembly (9) and the abutting portion (69), and the positioning is completed. The pipe limiting adjustment is performed by starting the first linear drive unit (62) to push the pressing platform (61) to move in the direction of the rotating mechanism (1), and the pressing portion (69) inside the pressing platform (61) moves accordingly, cooperating with the pipe limiting assembly (9) to initially limit the pipe, and then starting the hydraulic cylinder (36), the output end of the hydraulic cylinder (36) pushes the displacement seat (33) upward, and the roller (31) on the displacement seat (33) moves in the guide opening (30) of the connecting member (29), so that the bending seat (11) moves in the direction of the straight extension section (16), and cooperates with the straight extension section (16) to limit the pipe; To bend and unload the pipe, the rotating motor is started, which drives the bending disk (7) to rotate. When the bending disk (7) rotates, it drives the drive box (23), the bending seat (11) and the receiving platform (13) connected thereto to rotate together. At the same time, the second linear drive unit (63) is started, and the second linear drive unit (63) pushes the arc groove (66) to move in the direction of the storage integrated mechanism (3). Under the combined action of the rotating force and the thrust, the pipe is bent. When the pipe limiting assembly (9) rotates with the bending disk (7), the arc reinforcing plate (56) remains fixed. After the pipe is bent, the operator can remove the bent pipe, completing the entire pipe bending process.
