[0002] Automobile differential pressure tubes are mainly used to measure the pressure difference in the engine intake system, helping the engine control system to monitor and adjust the air flow to ensure combustion efficiency and emission performance. Ordinary differential pressure tubes are widely used in industry and other fields to measure the pressure difference inside pipelines or equipment. Relatively speaking, automobile differential pressure tubes are thin and long. In the production process, the bending work of differential pressure tubes is mainly completed by precise CNC equipment, which is costly.

[0003] A coil bending machine with authorization announcement number CN208991540U is disclosed, which can reduce the shaking of the coil when bending in the longitudinal and transverse directions, thereby reducing the impact on the subsequent bending accuracy. However, the device can only process a small amount of differential pressure pipes at a time. When there are many workpieces, it is difficult to effectively limit the workpieces and difficult to process in batches. In view of this situation, the utility model proposes a new solution.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] The pipe bender can be used to bend metal pipes according to the design requirements and make them into shapes and sizes that meet the requirements of automobile differential pressure pipes. The pipe bender controls the hydraulic or mechanical system to exert force on the metal pipes and bend them. It can achieve bending processes of different angles and radii. In the production process of automobile differential pressure pipes, the pipe bender can be used to perform precise bending processes on metal pipes.

[0024] like Figure 1 - Figure 3 As shown, the utility model provides a pressure differential pipe bending machine, which mainly includes a stable workbench 1. Two groups of pressure differential pipe placement components are arranged on the top of the workbench 1. The two groups of components are symmetrically arranged, which not only ensures the stable placement of the pressure differential pipe, but also facilitates subsequent processing operations. Two CNC cylinders 3 are also installed on the top of the workbench 1. The telescopic ends of the two CNC cylinders 3 are equipped with carrier blocks 4. A set of heating components is arranged between the two carrier blocks 4, which is specially used for preheating the pressure differential pipe before bending. This preheating treatment can significantly improve the plasticity of the material, making the bending process smoother, and can also effectively avoid problems such as cracks in the bending process.

[0025] The pressure differential tube placement components are arranged on both sides of the heating component. This layout is not only convenient for operation, but also ensures that the pressure differential tube always maintains a stable position during the processing.

[0026] like Figures 1 to 3 In order to achieve precise control of the pressure differential tube placement assembly, control components are also set on both sides of the workbench 1. These control components can accurately control the movement of the pressure differential tube placement assembly toward the heating assembly, thereby achieving precise positioning and processing of the pressure differential tube.

[0027] like Figure 1 to Figure 2 As shown, in order to ensure the smooth implementation of this embodiment, it is necessary to understand that the pressure differential tube placement assembly includes at least two stakes 6, and the tops of the stakes 6 are hinged with a lying plate 7, and the lying plate 7 is provided with a groove compatible with the pressure differential tube to be processed. During use, the pressure differential tube is placed on two symmetrical lying plates 7, which can allow the pressure differential tube to be placed stably, and during the bending process, when force is applied, the lying plate 7 is hinged with the stakes 6 to allow the pressure differential tube to bend and the two ends will not fall off the lying plates 7.

[0028] like Figure 2As shown, in order to ensure the smooth implementation of this embodiment, it is necessary to understand that the heating assembly includes a resistance heating wire 9 installed between two carrier blocks 4, and the power supply line of the resistance heating wire 9 is connected to the power supply after passing through one of the carrier blocks 4. A heat pipe 5 is also installed between the two carrier blocks 4, and the resistance heating wire 9 is located inside the heat pipe 5. The device is mainly used for bending pressure differential tubes for automotive accessories, and the pressure differential tubes for automobiles usually have thinner walls, thinner and longer tubes. Therefore, heating the heat pipe 5 and preheating the pressure differential tube by the resistance heating wire 9 can facilitate the bending of the pressure differential tube, and can also realize batch bending of pressure differential tubes of the same specification, with better effect.

[0029] like Figure 2 and Figure 3 As shown, in order to ensure the smooth implementation of this embodiment, it is necessary to understand that at least two slide grooves 12 penetrating from the bottom are opened on the top of the workbench 1. These slide grooves 12 not only provide channels for the movement of components, but the carrier plate 2 is a bridge connecting various components. Each group of piles 6 is installed on the carrier plate 2 to ensure its stability and reliability. A plug plate 201 is fixed to the bottom of the carrier plate 2, and the plug plate 201 can slide in the slide groove 12. When the pile 6 needs to be adjusted or moved, just gently push the carrier plate 2, and the plug plate 201 will slide smoothly in the slide groove 12, which is convenient for the precise positioning of the pile 6. The plug plates 201 on each side are connected by the top plate 11. This connection method enhances the stability of the structure. Side plates 13 arranged parallel to the top plate 11 are fixed on both sides of the workbench 1.

[0030] like Figure 2 and Figure 3 As shown, a threaded rod 8 is screwed to the side plate 13, and one end of the threaded rod 8 is rotated on one side of the top plate 11, so as to achieve fine-tuning and control of the piles 6 on the workbench 1. By rotating the threaded rod 8, the positions of the carrier plate 2 and the piles 6 can be adjusted, making the operation of the entire workbench 1 more flexible and convenient.

[0031] The equipment includes a stable workbench 1, with a pressure differential tube placement assembly and a CNC oil cylinder 3 arranged on the top, which are used to preheat the pressure differential tube to improve the plasticity of the material and make the tube bending process smoother. The pressure differential tube placement assembly is arranged on both sides of the heating assembly to facilitate operation and keep the pressure differential tube stable. The control component is used to accurately control the movement of the pressure differential tube placement assembly. The heating assembly includes a resistance heating wire 9 and a heat pipe 5, which are used to preheat the pressure differential tube to facilitate the tube bending work. A slide groove 12 is opened on the top of the workbench 1 to facilitate the movement of components. At the same time, stability and reliability are ensured by structures such as the plug plate 201 and the carrier plate 2. The threaded rod 8 is used to fine-tune and control the position of the stake 6.

[0032] To ensure the smooth implementation of this embodiment, it is necessary to understand that the maximum distance between the two symmetrically arranged lying plates 7 is smaller than the length of the pressure differential pipe to be processed, and each group of lying plates 7 is connected by a connecting rod 10 to control synchronization.

[0033] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is limited by the attached embodiments and their equivalents.
