There are many kinds of polishing machines, and the circular tube polishing machine is a common one. Mainly used for polishing round materials, it can polish round pipes of various raw materials, such as steel pipes, aluminum pipes, iron pipes and round bars, so it is called round pipe polishing machine.
Circular tube polishers, also known as centerless polishers and cylindrical polishers, are often used for rust removal and polishing in hardware manufacturing, vehicle parts, steel and wood furniture, instruments and machinery, standard parts and industries before and after electroplating. The workpiece processed by circular tube polishing machine has high brightness, which will not affect the original size of the workpiece, and is especially suitable for high-brightness polishing of the workpiece processed by centerless grinder.
2. What parts does the cylindrical polishing machine consist of?
The structure of circular tube polisher consists of machine body, workpiece fixing mechanism, polishing walking mechanism, loading and unloading mechanism, specification adjusting mechanism and control system.
1, fuselage
The welded steel structure has enough strength to ensure the compact structure, beautiful appearance and safe and stable operation of the whole machine.
2. Workpiece fixing mechanism
Installed on the fuselage, it is used to fix the steel pipe so that its polishing head can be aligned with the workpiece smoothly.
3. Polishing the walking mechanism
The stepless deceleration electrode is used to decelerate, and the polishing head is driven to move back and forth through sprocket transmission, and the walking speed is stepless adjusted.
4. Loading and unloading mechanism
In order to realize the automatic control of polishing, the cylinder controls the feeding, moving and unloading of the workpiece through the linear guide rail.
5, steel pipe specification adjustment mechanism
By lifting the workpiece positioning frame, the center height of the workpiece is ensured to be consistent with the center height of the polishing head.
6. Control system
The PLC programmable controller is used as the main control unit, and the program controls the automatic polishing process. It has a "manual/automatic" mode: the manual mode can be carried out by a single action, so as to adjust the specifications of the workpiece. The automatic state can adjust the polishing process and realize the automatic control of the whole polishing process.
3. What is the principle of the circular tube polishing machine?
The working principle of circular tube polishing machine is mainly based on the principle of centerless grinding. Let me give you a brief introduction:
The circular tube polishing machine consists of two mechanisms: polishing and feeding. By adjusting the feed of the grinding head, the polishing mechanism can carry out large-margin grinding or fine polishing on the workpiece, and can process workpieces with different specifications by adjusting the distance between the guide wheels. The feed mechanism adopts stepless speed change device, which can change the feed speed of the workpiece and achieve ideal grinding and polishing effect.
