[0021] The following will be described in detail with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, that is, a large number of specific details are given to provide a more thorough understanding of the present invention. However, for those skilled in the art, the present invention can be implemented without one or more of these details. In these examples, in order to avoid confusion with the present invention, some technical features known in the art are not described.

[0022] It should be understood that the present invention can be implemented in different forms and should not be construed as being limited to the embodiments presented herein. Therefore, they are only used as examples and cannot be used to limit the scope of protection of the present invention.

[0023] In addition, it should be noted that, unless otherwise specified, the technical terms or scientific terms used in this application should have the common meanings understood by technicians in the field to which the utility model belongs.

[0024] The multi-station thickening and expanding machine realizes accurate expansion and thickening processing of pipes with different diameters. The equipment consists of multiple stations. In the utility model, there are three stations, namely the first station 1, the second station 2 and the third station 3. Each station is optimized for a specific pipe diameter to ensure the accuracy and efficiency of processing. In addition, the equipment is also equipped with a high-frequency heating module 4, which is used to heat the pipe before expansion and during the station switching process to cope with complex pipe expansion structures and improve the quality and efficiency of expansion.

[0025] In order to achieve seamless connection between workstations and precise displacement of pipe fittings, this equipment is equipped with an efficient conveying mechanism B. This conveying mechanism B is not only responsible for accurately displacing pipe fittings A between workstations, but also assists the operation of high-frequency heating module 4. Conveying mechanism B consists of an X-axis moving unit 5 and a Y-axis moving unit 6 mounted thereon. The coordinated work of these two axes enables pipe fittings A to be accurately positioned at each workstation. In addition, conveying mechanism B also includes a Z-axis moving unit 7, which is used to deliver pipe fittings A to the high-frequency heating module 4 to ensure the need to heat pipe fittings before or during pipe expansion at the workstation, and the switching process can also ensure that the heating of pipe fittings is carried out when the heating is optimal.

[0026] A clamping mechanism C is specially designed on the Z-axis moving unit 7 to firmly clamp the pipe A during the processing. The use of this clamping mechanism C can prevent the pipe from shifting during the processing and ensure the processing accuracy; on the other hand, it can also protect the pipe from damage during the processing and improve the processing quality of the pipe.

[0027] The expansion head 8 is installed in front of the output end of the hydraulic power G of the whole equipment to align with the pipe mouth of the pipe fitting A. After the expansion head 8 is inserted into the pipe mouth of the pipe fitting, it provides the necessary expansion force for thickening and expanding the pipe fitting. The application of this hydraulic power not only provides powerful processing capabilities, but also ensures the stability and reliability of the pipe expansion process.

[0028] The expansion head 8 has multiple expansion sections with different diameters. The diameter of the front expansion section is equal to or smaller than the diameter of the pipe A, which can easily penetrate into the pipe A to limit and stabilize the pipe A. When the hydraulic power G pushes, the expansion head 8 further penetrates the pipe A. At this time, the expansion section with a larger diameter is inserted into the pipe opening of the expanded pipe A. The expansion head of each station has expansion sections with different diameters, so it can be switched between stations to complete the expansion requirements of complex pipes. The coordinated setting of the high-frequency heating module 4 makes the expansion of complex pipes more handy.

[0029] For example, the X-axis moving unit 5 first aligns the Y-axis moving unit 6 with the first station 1 for the pipe A, and then the Y-axis moving unit 6 controls the pipe A to contact the expanding head of the first station 1 and perform the first expansion. Then the Y-axis moving unit 6 controls the pipe A to retreat, and the Z-axis moving unit 7 moves upward, and the X-axis moving unit 5 can simultaneously move upward in the X-axis direction to move the pipe A to the high-frequency heating module 4, and then the Y-axis moving unit 6 controls the pipe A to penetrate into the high-frequency heating module 4 to heat the pipe A, and then the X-axis moving unit 5, the Y-axis moving unit 6 and the Z-axis moving unit 7 work together to move the pipe A to the second station 2 for processing and expansion, and so on, the expansion and thickening of the pipe mouth of the pipe A can be completed.

[0030] In general, this multi-station hydraulic thickening and expanding machine achieves efficient and precise processing of complex pipe fittings through its precise design and efficient mechanism. It is an indispensable high-end equipment in modern industrial production.

[0031] Furthermore, as an improvement to the present invention, the conveying mechanism performs programming control on the X-axis moving unit 5 , the Y-axis moving unit 6 and the Z-axis moving unit 7 through a multi-axis stepping servo motor controller K.

[0032] In this embodiment, the multi-axis stepper servo motor controller K is commercially available. This type of controller has a high degree of integration and can complete the expansion operation of the pipe A by the three-axis moving unit using simple logic settings, which is very convenient.

[0033] Furthermore, as an improvement to the present invention, the conveying mechanism B of the multi-station hydraulic thickening and expanding machine is a sophisticated mechanical device, which is composed of three basic parts: an X-axis moving unit 5, a Y-axis moving unit 6 and a Z-axis moving unit 7. Each part is driven by a high-precision servo motor, ensuring the precise displacement and stable clamping of the pipe A between each station.

[0034] The X-axis moving unit is the basis of the entire conveying mechanism B, which includes two precisely machined X-axis guide rails 51 and an X-axis bracket 52 mounted on the two guide rails 51. The X-axis bracket 52 is equipped with a high-precision X-axis servo motor 53, which is responsible for driving the X-axis bracket 52 to slide smoothly and quickly on the X-axis guide rail 51, thereby achieving accurate positioning of the pipe A in the X-axis direction.

[0035] The Y-axis moving unit 6 is an extension of the X-axis moving unit 5, and includes a Y-axis bracket (not shown) fixed on two Y-axis guide rails 61 on the X-axis bracket. A Y-axis servo motor 62 is installed on one side of the Y-axis bracket, and the motor drives the bracket to slide on the Y-axis guide tube 61, so that the pipe A can be finely displaced in a plane.

[0036] The Z-axis moving unit 7 is the vertical moving part of the entire conveying mechanism B, which includes a Z-axis bracket 71 fixed on the Y-axis bracket, and two Z-axis guide rails 72 arranged on the bracket. The Z-axis servo motor 73 is installed at the upper end of the bracket, and its drive shaft is connected to the clamping mechanism, which is responsible for vertically moving the pipe A to the position of the high-frequency heating module 4. This design enables the pipe A to be accurately delivered to the high-frequency heating module 4, ensuring the accuracy and efficiency of the heating process.

[0037] The design of the entire conveying mechanism B fully considers the smooth transition and precise processing of the pipe A between each station. Through the precise coordination of the three axial servo motors, efficient and precise handling and positioning of the pipe is achieved. This design not only improves production efficiency, but also ensures the stability and safety of the pipe A during processing. It is the key to the efficient and precise processing of this multi-station thickening and expanding machine.

[0038] Further, as an improvement to the present invention, the clamping mechanism C includes a clamping bracket that moves in the Z-axis direction of the Z-axis moving unit, and the clamping bracket is provided with a clamping operation area for clamping partial pipe fittings, which is composed of a pressure head installed on the output end of a clamping servo motor and a plurality of supporting blocks provided on the clamping bracket, and a pipe support seat arranged on the side of the operation area.

[0039] The clamping mechanism C of this multi-station hydraulic thickening and expanding machine is a well-designed device, which is responsible for firmly clamping the pipe A during the processing, ensuring the stability and safety of the pipe A during displacement and processing. The key part of the clamping mechanism C is a clamping bracket that can be displaced in the Z-axis direction of the Z-axis moving unit.

[0040] This clamping bracket is the core of the clamping mechanism C. It is designed to move up and down precisely along the Z-axis guide rail, and can also adapt to pipes A of different lengths in conjunction with the Y-axis moving unit. The bracket is provided with a plurality of holding blocks 91. In order to achieve precise control of clamping, a high-precision clamping servo motor 93 fixed on a clamping bracket seat 92 is also provided above the holding blocks 91. A pressing head 94 is installed at the output end of the clamping servo motor 93. The pressing head 94 works in conjunction with the holding blocks 91 on the clamping bracket, whose positions and shapes are carefully designed according to the shape and size of the pipe A, to form a clamping system that ensures that the pipe A can be clamped evenly, stably and reliably during the processing. When the clamping servo motor 93 is started, the pressing head 94 will apply appropriate pressure to the pipe A through the precise control of the clamping servo motor 93, thereby achieving a stable clamping of the pipe.

[0041] This design enables the clamping mechanism C to adapt to various shapes and sizes of pipe fittings A, which not only improves the clamping stability during processing, but also reduces the risk of damage to the pipe fittings during processing. Through this precise clamping control, this multi-station thickening and expanding machine can ensure the position accuracy and processing quality of the pipe fittings A during processing, providing a solid foundation for efficient and accurate pipe processing.

[0042] Furthermore, in order to further improve the stability and safety of the pipe A during the processing, and also as an improvement to the implementation of the utility model, a clamping and fixing station is specially set. This station is located between the station and the conveying mechanism, and plays a transition and fixing role, ensuring the stability and safety of the pipe during the conveying process.

[0043] The core part of the clamping and pressing station is a bottom pipe support 95, which is designed to stably support the pipe A. Above the bottom pipe support 95, an upper pipe support 97 driven by the hydraulic cylinder 96 is provided. The upper pipe support 97 forms a close fit with the bottom pipe support 95, and the pipe A can be effectively clamped and pressed by the hydraulic cylinder 96.

[0044] When the pipe A needs to be fixed, the hydraulic cylinder 96 pushes the upper pipe holder 97 downward to make it closely contact with the bottom pipe holder 95, thereby applying sufficient clamping pressure to the pipe A. This clamping and fixing method can not only ensure the stability of the pipe A during transportation, but also prevent the pipe from shifting or vibrating during processing, thereby improving the processing accuracy and quality.

[0045] In addition, the setting of the clamping and pressing station has greatly improved production efficiency. During the interval between the pipe A moving from one station to another, the clamping and pressing station can quickly fix the pipe A, reducing the stop time of the pipe during transportation and ensuring the continuity and efficiency of the production process.

[0046] In general, the setting of the clamping and pressing station is also an important part of the design of this multi-station thickening and expanding machine. It provides a stable fixing point, which significantly improves the stability and safety of the pipe A during the processing. This design reflects the equipment designer's emphasis on improving production efficiency and processing quality, and also shows the exquisiteness and attention to detail of this equipment.

[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein by equivalents.
