Main inspection elements for rolling machine
The rolling machine is a combination of mechanical, hydraulic, electrical and automation technology. It has the advantages of beautiful appearance, compact structure, small volume, easy installation, high degree of automation and reasonable price. In operation, it should pay attention to the inspection work of each part. Here is a brief introduction to the main inspection elements of the rolling machine.
1. Rolls: Rolls are the main part of the rolling machine, which directly contacts and drives the material to realize rolling. The surface of the roll should be kept clean and smooth, no scratches, scratches, cracks and pitting; the surface hardness should be kept above HRC50. In addition, the roll surface should be uniform and there should be no wear marks (the wear marks should be evenly distributed).
2. Bearings: Rolling masine bearings are roll-bearing bearings, which are divided into rolling bearings, sliding bearings and rigid bearings. Check whether the bearing clearance space is reasonable and before starting the rolling machine, be sure to check the lubricating oil temperature of the bearing.
3. Gearbox: Gearbox is the transmission mechanism of rolling machine, which reduces the speed of motor and increases the output torque. It is necessary to check whether the transmission parts are intact and whether the bearings are correctly filled with lubricating oil.
4. Motor: The motor is the power source of the rolling machine. It is necessary to check whether the motor stator winding is intact and whether the voltage static stability is good; whether the rotating parts are intact, the lubricant is normal, and the fan is normal; whether the grounding of the motor casing is reliable and the grounding resistance meets the requirements.
5. Reducer: The reducer is installed between the motor and the roll to reduce the speed and increase the torque. It is necessary to check whether the parts of the reducer are complete and correctly assembled, whether the connection is tight, and the oil level and oil quality meet the requirements.
6. Electrical components: The electrical components of the rolling machine include circuit boards, switches and buttons, temperature detectors and other components, which must be kept clean and dry without any leakage. Check whether the terminals and joints are secure, and whether the wiring is correct.
Regular inspection and maintenance of the above elements can help to improve the production efficiency of rolling machine and extend its service life. In practical operations, the operator should pay attention to observe the condition of all parts of the machine at any time, and timely handle the fault and properly maintain the machine to ensure its normal operation.
