[0028] To further illustrate each embodiment, the present invention provides drawings, which are part of the disclosure of the present invention and are mainly used to illustrate the embodiments. They can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, ordinary technicians in the field should be able to understand other possible implementation methods and advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0029] According to an embodiment of the utility model, a pipe bending device in a multi-mode pipe bending machine is provided.

[0030] The present invention is now further described in conjunction with the accompanying drawings and specific implementation methods. Figure 1-Figure 9 As shown, the pipe bending device in the multi-mode pipe bending machine according to the embodiment of the utility model includes a pipe bending machine body 1, and a pipe bending mechanism 3 is arranged on one side of the pipe bending machine body 1 through a connecting plate 2. The pipe bending mechanism 3 includes a sliding component 4 installed on one side of the connecting plate 2, and a connecting seat 5 is arranged on one side of the sliding component 4. An auxiliary component 6 and a rotating component 7 located on one side of the auxiliary component 6 are arranged in sequence inside the connecting seat 5. A pipe bending mold 8 is arranged at the top of the sliding component 4 and the rotating component 7. Specifically, the sliding component 4 and the rotating component 7 belong to mature technologies in this field, so they are not described in detail here. A mold fixing component 9 is arranged at the top of the pipe bending mold 8.

[0031] It needs to be explained that the pipe bending machine body 1 is a mechanical equipment specially used for bending pipes. Its working principle mainly relies on applying external force to the pipe to cause it to bend and deform to achieve a predetermined bending angle and radius. According to different operating methods and functions, pipe bending machines can be divided into mechanical pipe bending machines, hydraulic pipe bending machines, CNC pipe bending machines, rotary bending pipe bending machines, etc.

[0032] Taking the CNC pipe bending machine as an example, its working principle is mainly based on CNC technology (numerical control technology). The bending process is controlled by programming to achieve precise bending of the pipe. The specific principle includes the following links:

[0033] The operator needs to program and set according to the requirements of the pipe bending, such as bending angle, bending radius and number of bends. These parameters are input into the control system of the CNC pipe bending machine. Before starting processing, the CNC pipe bending machine will automatically position the pipe to ensure that the starting position of the pipe meets the requirements in the programming.

[0034] According to the preset program, the CNC pipe bender controls the movement of the bending die and the supporting die through its drive system (motor, hydraulic system or servo motor), which is equivalent to the sliding assembly 4 and the rotating assembly 7 in the utility model. The pipe is fixed during the bending process, and the pipe bender body 1 automatically completes the bending operation according to the required bending angle and radius. During the whole process, the control system will accurately control the bending speed and pressure to ensure the accuracy and quality of the bending.

[0035] In one embodiment, for the auxiliary component 6, the auxiliary component 6 includes a sliding cavity 601 opened at the top of the connecting seat 5, a screw rod 602 and a fixed rod 603 are arranged inside the sliding cavity 601, one side of the screw rod 602 is connected to the output shaft of the servo motor 604, and the servo motor 604 is installed on one side of the connecting seat 5, and a sliding plate 605 is sleeved on the outer side of the screw rod 602 and the fixed rod 603, and a baffle 606 is arranged on the top of the sliding plate 605; the auxiliary component 6 also includes two groups of electric telescopic rods 607 arranged inside the connecting seat 5, a connecting plate 609 is arranged at the top of the electric telescopic rod 607, and two groups of sliding sleeves 610 are arranged at the bottom of the connecting plate 609. , and the sliding sleeve 610 is sleeved inside the connecting rod 611; the connecting rod 611 is installed on one side of the two sets of electric telescopic rods 607, and the intermediate frequency control cabinet 612 is arranged on both sides of the top of the connecting plate 609. Specifically, the intermediate frequency heater 608 is arranged on both sides of the intermediate frequency control cabinet 612 through the wire, so that the pipe to be bent can be preheated according to the material of the pipe. The preheating reduces the bending strength of the pipe and reduces the force required for bending, which can reduce the risk of pipe breakage or deformation. The baffle 606 is driven to slide by the servo motor 604, which can protect the intermediate frequency heater 608 when bending the pipe that does not need to be heated, so as to avoid damage to it and reduce its service life.

[0036] It should be explained that a medium frequency heater is a device that uses medium frequency (generally in the range of 1kHz to 10MHz) current to generate heat. It is widely used in the field of industrial heating, especially in metal processing, heat treatment, welding and other processes. The core principle of medium frequency heating is electromagnetic induction, in which an alternating current flows through a coil (induction coil), generating a changing magnetic field, which in turn generates an induced current (i.e. eddy current) in a conductive material (such as metal). The eddy current generates heat inside the material, thereby heating the material.

[0037] The working principle of the auxiliary component 6 is as follows: the operator starts the servo motor 604 through the console, and then the screw 602 rotates under the drive of the servo motor 604, and during the rotation, the sliding plate 605 is driven to move horizontally inside the sliding cavity 601, thereby driving the baffle 606 at the top of the sliding plate 605 to move, and when the baffle 606 moves out of the top of the connecting seat 5, the electric telescopic rod 607 is started, and the connecting plate 609 is driven to move upward under the action of the two groups of electric telescopic rods 607. During the movement, the sliding sleeve 610 slides inside the connecting rod 611 to avoid tilting during the upward movement. When the pipe can pass through the medium frequency heater 608 and the pipe can be heated by the medium frequency heater 608, the movement stops.

[0038] In one embodiment, for the above-mentioned mold fixing assembly 9, the mold fixing assembly 9 includes a connecting frame 901 installed on the top of the sliding assembly 4 and one side of the rotating assembly 7, and an electric telescopic rod 902 is arranged in the middle of the connecting frame 901. The outer side of the electric telescopic rod 902 is connected to a support 904 through a connecting shaft 903. The bottom end of the support 904 is connected to the sliding assembly 4 and the rotating assembly 7 through a bolt 912. A connecting seat 905 is arranged in the middle of the support 904, and a connecting shaft 906 is connected to the inside of the connecting seat 905; connecting rods 907 are arranged on both sides of the connecting shaft 906, and the two sets of connecting rods 907 are arranged on both sides of the connecting shaft 906. 07 is connected to the electric telescopic rod 2 902 through a block 908, and the bottom end of the block 908 is connected to the connecting seat 905; a connecting rod 909 is arranged in the middle of the top of the connecting seat 905, and a plug rod 911 is arranged on one side of the connecting rod 909 through a transfer shaft 910, and a socket matched with the plug rod 911 is arranged at the position of the specific sliding component 4 and the rotating component 7, so that the pipe bending mechanism 3 can be suitable for pipes of different diameters and materials, and can flexibly respond to the processing needs of pipes of various specifications, ensuring that a pipe bending mold 8 matching the pipe is used in the pipe bending process, thereby improving the quality and accuracy of the pipe bending.

[0039] The working principle of the mold fixing assembly 9 is as follows: when the pipe bending mold 8 needs to be replaced, the electric telescopic rod 2 902 is started through the external console, and then the stopper 908 in the middle of the connecting rod 907 is driven to move in the shortening direction under the shortening effect of the electric telescopic rod 2 902, and in the process of movement, the connecting rod 909 at its bottom end is driven to move with it, and then the connecting rod 909 drives the outer plug rod 911 to lift up, and after the plug rod 911 is lifted up, it leaves the inside of the pipe bending mold 8, thereby disconnecting from the pipe bending mold 8, and the pipe bending mold 8 is in an independent state, and can be replaced with a pipe bending mold 8 of different sizes, materials, and sizes as needed.

[0040] In order to facilitate understanding of the above technical solution of the present invention, the working principle or operation method of the present invention in the actual process is described in detail below.

[0041] In actual application, the staff transfers the pipe to the pipe bending mechanism 3 through the mobile clamping part of the pipe bending machine body 1, and then uses the mold fixing component 9 to replace the corresponding pipe bending mold 8 according to the diameter, size and material of the pipe to avoid deviation in the process of bending and cause bending failure. After the replacement is completed, it is determined whether preheating is required before bending according to the material of the pipe. If preheating is required, the auxiliary component is turned on and the auxiliary component 6 is used to preheat the pipe in advance. After the preheating is completed, the next step is carried out. If preheating is not required, the auxiliary component 6 and the rotating component 7 are used to bend the pipe directly according to the required shape.

[0042] In summary, with the aid of the above technical solution of the utility model, the utility model has a simple structure and is easy to operate. By setting the auxiliary component 6 and the mold fixing component 9, it can not only reduce the force required for bending during the pipe bending process, reduce the risk of pipe breakage or deformation, but also facilitate the replacement of the pipe bending mold 8. The utility model can preheat the pipe to be bent according to the material of the pipe by setting the auxiliary component 6, reduce the bending strength of the pipe by preheating, reduce the force required for bending, and reduce the risk of pipe breakage or deformation. The servo motor 604 drives the baffle 606 to slide, and the intermediate frequency heater 608 can be protected when bending the pipe that does not need to be heated, so as to avoid damage to it and reduce its service life. The utility model uses the mold fixing component 9 to make the pipe bending mechanism 3 suitable for pipes of different diameters and materials, and can flexibly respond to the processing requirements of pipes of various specifications, ensuring that the pipe bending mold 8 matching the pipe is used during the pipe bending process, thereby improving the quality and accuracy of the pipe bending.
