Technical analysis and application prospects of two-step seamless pipe expanding machine: In modern manufacturing industry, the processing and forming technology of pipes continues to develop, especially in the fields of petroleum, chemical, aerospace and construction, and the demand for seamless pipes is growing. In order to meet this market demand, the two-step seamless pipe expanding machine, as an efficient and accurate processing equipment, has gradually received attention. This paper will deeply discuss the working principle, technical characteristics, application scenarios and future development trend of the two-step seamless pipe expanding machine.
One, two step seamless tube expanding machine working principle
The core principle of the two-step seamless pipe expanding machine is to use two different reaming processes to gradually expand the raw material pipe to the required diameter and wall thickness. The equipment is generally composed of feeding system, pipe expansion system, control system and discharging system.
### 1. Feed system
The feed system is responsible for accurately feeding the raw material pipe into the pipe expanding machine. Usually a manipulator or conveyor belt is used to transport the pipe to the expansion position to ensure that the pipe remains stable during the entire expansion process and is not easy to slip or offset. #### 2. Pipe expansion system
The pipe expanding system is the core part of the two-step seamless pipe expanding machine, which is mainly composed of two pipe expanding dies and a driving device. The expansion process is divided into two steps:
- ** One-step tube expansion ** : In this stage, the tube is fed into a tube expansion mold, and the shape and size inside the mold gradually expand the diameter of the tube. By applying uniform pressure to the pipe, it is formed in the mold, and the initial expanding effect is achieved.
Two-step tube expansion ** : After one-step treatment, the tube will enter the second tube expansion mold. At this time, the mold plays a decisive role in the further expansion and molding of the pipe. Two-step tube expansion usually involves higher pressure and finer control to ensure dimensional accuracy and surface finish of the final product.
#### 3. Control system
Modern two-step seamless pipe expanding machine is generally equipped with advanced control system, which can monitor the parameters of the pipe expanding process in real time, including pressure, temperature, speed and so on. This system is generally managed by PLC (Programmable logic controller) to ensure the accuracy and stability of operation. Through data acquisition and feedback, operators can adjust equipment parameters in time to optimize the processing process.
#### 4. Discharge system
The discharge system is responsible for transporting the expanded product to the subsequent process. The system is usually designed as an automated structure, which can effectively improve production efficiency and reduce manual intervention.
