This summer's summer weather is particularly hot. It is particularly important to maintain the sprinkler . A considerable number of sprinkler owners will simply and conveniently use tap water instead of antifreeze. In fact, this is a wrong practice because there are many impurities in the water. It is not advisable to use water instead of antifreeze to leave impurities and sediments on engines , tanks, etc. Such conditions occur every year, such as the spontaneous combustion of green sprinklers in summer. At this time, we recommend that vehicles mainly check the green sprinklers in a timely manner and find that there are problems with the green sprinklers and repair them in time to avoid unnecessary losses.

There are two main reasons for the spontaneous combustion of green sprinklers. One is the leakage of the green sprinkler and the other is the leakage of oil. This is related to the improper use of green sprinklers for daily use. The green sprinkler that causes spontaneous combustion is generally based on old cars. The owner usually does not care about the greening of the sprinkler, causing some parts of the car to be worn out or the lines are damaged. This way, the line of the car is prone to leakage, and the fuel tank is subjected to prolonged exposure. Corrosion is also prone to oil leakage; in addition, some consumers install anti-theft devices, audio equipment, or retrofitting green sprinklers to green sprinklers after they buy a car, destroying the green sprinkler’s own lines, and sometimes lax lines and summer weather. Hot, green sprinklers are exposed to the sun for a long time and it is easy to cause spontaneous combustion.

Light Duty Spinning

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.
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.
