[0031] Further description of the above structure is as follows:
[0032] The output end of the driving motor 13 is equipped with a gear, which is connected to a transmission gear 26 via a belt 25. The transmission gear 26 is sleeved and fixed on the outside of the shaft. The shaft cooperates with a bearing seat fixed on the side edge of the support frame 11. A main gear 27 is fixed at one end of the shaft, and a bending wheel 24 is fixed at the other end of the shaft.
[0033] There are three bending wheels 24 in the bending assembly 2, and the bending wheels 24 are distributed in a triangular shape. The end of the shaft connected to the bending wheel 24 at the bottom is cooperated with a baffle 22, and the baffle 22 is fixed to the upper side end of the support frame 11. The bending wheel 24 at the top is set to rise and fall relative to the bracket 21.
[0034] The bending assembly 2 3 also includes a bracket 2 31 fixed to the upper side of the support frame 11, a support 2 35 is arranged inside the bracket 21, and a bearing seat fixed on the lower side of the support 2 35 cooperates with the main shaft 29; a guide rod 32 is fixed to the upper side of the support 2 35, and the guide rod 32 is passed through the top of the bracket 2 31; three bending rollers 33 are arranged, and the bending rollers 33 are distributed in a triangular shape, and the shaft rod connected to the bending rollers 33 located at the bottom is also adapted to be installed with a bearing seat.
[0035] The pipe bending machine significantly improves the accuracy, efficiency and flexibility of pipe bending operations. The specific description of its technical solution is as follows:
[0036] The core power source of the pipe bender is the drive motor 13 installed on the workbench 1. Through the combination of the belt 25 and the transmission gear 26, the power is transmitted to the first bending assembly 2 efficiently and smoothly, which not only ensures the stability and efficiency of power transmission, but also realizes the synchronous cooperation of the double bending assemblies through the precise meshing of the main gear 27 and the sub-gear 34, ensuring precise control during the pipe bending process.
[0037] The first bending assembly 2 is driven by a pneumatically controlled telescopic mechanism 23 to move the first support 28 up and down, realizing precise position adjustment of the bending wheel 24. The three bending wheels 24 are arranged in a triangular distribution. Through the layout at different upper and lower positions, it ensures that the pipe is evenly stressed during the bending process, reducing deformation and damage. The setting of the baffle 22 effectively restricts the pipe, preventing deviation during bending.
[0038] The second bending assembly 3 is arranged opposite to the first bending assembly 2. Through the structural support of the second bracket 31 and the guide rod 32, it ensures the stable operation of the bending roller 33. Also using a triangular distribution of three bending rollers 33 further enhances the stability during the bending process and is suitable for handling complex pipe bending requirements.
[0039] In addition, through the application of the telescopic mechanism 23, the pipe bender can adapt to pipes with different diameters and wall thicknesses, greatly improving the flexibility and application range of the equipment. This design not only simplifies the operation process but also reduces the frequency of mold replacement, improving production efficiency.
[0040] The use of multiple bearing seats effectively reduces the friction and wear of moving parts, improves the smoothness and service life of mechanical movement. The bearing seat design of the first support 28 and the second support 35 ensures the stable rotation of the main shaft 29 and the bending roller 33, reduces mechanical failures, and improves the overall stability and durability.
