Lubrication system of punch press machine

In today's rapidly developing manufacturing industry, punch press machine are important metal processing equipment, and their performance and stability are crucial for improving production efficiency. The lubrication system of the punch press machine, as a key part to ensure the smooth operation of the equipment, is undergoing a technological innovation. Recently, the innovative technology of punch press machine lubrication system has attracted widespread attention in the industry, and this technology is expected to provide strong support for the efficient development of the manufacturing industry.

1. The importance of lubrication system

During the operation of a punch press machine, friction and wear will occur between its various components. Without proper lubrication, it can lead to overheating, increased wear, and even malfunction of the components. Therefore, the main function of the lubrication system is to reduce friction, decrease wear, cool components, prevent corrosion, and help the punch maintain smooth operation.

2. Types of lubrication systems

The lubrication system of punch press machines is usually divided into multiple types to meet the needs of different punch press machines. Among them, the progressive circulation type thin oil lubrication system is a relatively common one. The system provides lubricating oil through a thin oil lubrication station and distributes it quantitatively to each lubrication point through a progressive distributor. In addition, there are different types of centralized lubrication systems such as resistance type centralized lubrication system, volumetric centralized lubrication system, oil mist centralized lubrication system, and oil air centralized lubrication system, each with its specific application scenarios and advantages.

3. Composition and working principle of progressive circulation thin oil lubrication system

The progressive circulation thin oil lubrication system mainly consists of a thin oil lubrication station, a pump unit, an overflow valve, a high-pressure filtration system, a tubular throttle valve, a speed regulating valve, a heating device, a liquid level device, and a progressive distributor.

The working principle is that the pump unit extracts lubricating oil from the thin oil lubrication station and delivers it to various lubrication points through high-pressure pipelines. During the transportation process, the lubricating oil will pass through a high-pressure filtration system to filter out impurities and ensure the cleanliness of the lubricating oil. The progressive distributor distributes oil quantitatively based on the oil demand of each lubrication point. When a lubrication point requires lubrication, the progressive distributor will open its corresponding oil outlet to allow lubricating oil to flow into that lubrication point. At the same time, the system also regulates the flow and pressure of lubricating oil through components such as speed control valves and tube type throttle valves to ensure lubrication effectiveness.

4. Maintenance and management of lubrication system

In order to ensure the normal operation of the press lubrication system, regular maintenance and management are required. This includes:
1. Regular inspection: Regularly inspect the lubrication system of the punch press machine, including checking the oil level, quality, and wear of each component of the lubricating oil.
2. Replace lubricating oil: Regularly replace the lubricating oil according to the usage of the punch and the replacement cycle of the lubricating oil. During the replacement process, the lubrication system should be thoroughly cleaned to avoid performance degradation caused by the mixing of new and old oil.
3. Cleaning the filter: Regularly clean the high-pressure filtration system to ensure its filtration efficiency. When the filter is severely clogged, the filter element should be replaced in a timely manner.
4. Adjust the distributor: Adjust the working parameters of the progressive distributor in a timely manner according to the working condition of the punch press machine and the oil demand of the lubrication point.

5. Record and maintenance: Establish detailed lubrication system maintenance records, including maintenance time, maintenance content, replaced parts, etc., for subsequent tracking and management.

5. Malfunctions and troubleshooting of lubrication system

The lubrication system of the punch press machine may experience various malfunctions during use, such as motor failure, oil bubbles or no oil discharge from the pump unit, low system working pressure or overload, etc. The following measures can be taken to eliminate these faults:
1. Motor not running: Check if the motor is burnt out or if the power supply is disconnected, and replace or repair it accordingly.
2. If there are bubbles or no oil in the oil discharged from the pump unit: Check whether there is air in the pump body or whether there is leakage at the connections of various pipelines, and carry out corresponding exhaust or fastening treatment.
3. Low system working pressure: Adjust the relief valve to the required pressure and check for oil leakage in the pipeline.
4. System overload: Clean or replace high-pressure oil filters in pipelines blocked by foreign objects, replace flattened pipelines or clean lubrication point oil tanks, and disassemble progressive distributors for foreign object cleaning or maintenance.
In summary, the lubrication system of the punch press machine is of great significance in ensuring its normal operation and extending its service life. By selecting the appropriate type of lubrication system, conducting regular maintenance and management, and promptly troubleshooting, the stable operation of the press lubrication system can be ensured, thereby improving the production efficiency and processing quality of the press.
