The principle of metal spinning process is to cover the processed metal blank (tube blank) on the mandrel, while the blank is pressed at the end of the mandrel by the tail, and rotates with the mandrel along the spindle, and the rotary wheel moves along the mandrel.

The continuous autumn rain in the past few days has made the rice farmers headache and helpless. The county agricultural machinery department actively organized more than 20 dryers for cooperatives to ensure the harvest of the first season and the return of the grain. "The two days of grain farmers have sent the harvested wet valley to dry. Before the sun was hard and limited by the venue, it took two or three days to dry. It took time and labor to look at the weather, and it was not good for a season of sweat. The white flow now. Now the dryer has been put on the market, it is efficient and environmentally friendly, and is very popular among rice farmers!†Talking about the problem of drying the sun and mechanical drying, Chen Changjun, chairman of the Niujiao Agricultural Machinery Cooperative, was very emotional. It is understood that a 12-ton dryer can dry 15 tons of rice in 20 hours, and the service fee per ton is 140-150 yuan. The efficiency of drying per ton of rice is more than 20 times that of artificial sun-dried, saving more than 30%. .
"With the help of the dryer, the rice is no longer necessary to look at the face of God!" Peng Taiqiao, a large grain grower in Xiaojiandong Village, Maojun Town, was relieved. This year he ran the rice produced by more than 200 acres of farmland. In the past few days, it has dried more than 100 tons in the drying field, ensuring a bumper harvest!
Generally speaking, light automatic spinning machines have structural advantages similar to ordinary lathes. However, in order to meet the requirements of the above spinning process, large spinning machines usually have the following 11 core advantages.
1. The automatic spinning machine bed, main shaft, and transmission system, rotating wheel frame, tailstock and other parts should have sufficient rigidity, and also have a heavier worktable, a thicker guide rail, and a thick wall bearing support And cabinets.
2. The horizontal and longitudinal feed mechanisms of the rotary frame are mostly driven by hydraulic transmission or a combination of mechanical and hydraulic pressure to generate sufficient spinning pressure and balance step-less speed regulation to meet process requirements.
3. Ordinary automatic spinning machines usually use one rotary wheel, but there are multiple auxiliary forming wheels (flanging wheel, curling wheel, etc.). The number of rotating wheels or rotating frame of the powerful automatic spinning machine is 2 to 3 (the general type is 2, and the cylindrical part spinning machine is mostly 2 to 3), and is symmetrical to the spindle axis. Balancing the radial force during spinning, reducing the bending deflection, deflection, and vibration of the spindle and core mold provides a prerequisite for improving the accuracy of spinning parts. This correspondingly requires the rotary wheel to have a higher horizontal (such as a special spinning machine for cylindrical parts) or a longitudinal (such as a general-purpose automatic spinning machine) synchronous feed accuracy. However, a rotary wheel is used for the light and powerful automatic spinning machine.
4. The main shaft has sufficient transmission torque and power. According to the specific process requirements, it can meet the constant torque or constant power adjustment. In addition, it is best to make the spindle speed and the longitudinal feed speed of the rotary wheel steplessly adjustable. On the one hand, it can meet the arbitrary selection requirements of the spinning process; on the other hand, it can maintain the surface rotation speed of the core mold during the spinning process. Possibility of constant feed per revolution.

Recently, in the rice drying field of the Lanjiao Nongjiao Agricultural Machinery Cooperative, three 12-ton dryers were fully loaded under the control of the workers’ masters, and a bag of wet valleys on the conveyor belt in the rumble of the rumble Instantly swallowed by "big monsters."
