Description

Automatic dosing system processing method

The invention provides a method for processing an automatic dosing system, in particular to automatically replenish the fuel tank of each processing machine by using an automatic dosing system, thereby effectively saving the labor and cost of manual inspection and replenishment. The concentration of the cutting fluid in the fuel tank can be maintained, thereby improving the precision of the workpiece machining and extending the service life of the cutting tool.

According to the current situation, the manufacturing industry is facing labor shortages and environmental awareness, labor and operating costs, and labor-intensive and technologically intensive pressures. Most of the industry responds to costs by means of industrial migration or the introduction of foreign workers. Rising, or using production line automation technology and fixture assistance to improve business quality and reduce costs, in order to reduce manpower, save manufacturing hours and increase production capacity.

However, in the automation of production lines in the manufacturing industry, the metropolis is applied to different workstations or locations within the plant for various processing processes such as processing, inspection, cleaning, assembly, quality control, warehousing and transportation, among which the production process is Using a variety of processing tools to produce a variety of required components, products, such as lathes, milling machines, planers, drilling machines or numerical control processing tools (NC or CNC), etc., while in the metal machining process, because the cutting tool is cutting the workpiece When the workpiece will generate a lot of heat and pressure, the cutting fluid is generally used to assist the workpiece and the cutting tool to cool and cool, so as to improve the accuracy of the workpiece size. Extend the service life of cutting tools and prevent rust or corrosion of workpieces.

Furthermore, the cutting fluid can be mainly divided into three types: oily cutting oil, water-soluble cutting oil and synthetic cutting fluid. For different workpiece materials, it is necessary to use appropriate cutting fluid to process during the cutting process, wherein the water-soluble cutting oil is Mineral oil, emulsifier, anti-rust additive and other additives such as anti-corrosion agent and defoamer, and have a wide range of cutting ability, large pollution tolerance and excellent emulsion stability, in order to maintain cutting fluid The performance of the product, reducing oil and gas emissions and reducing costs, in the conventional monitoring project of cutting fluid, the cutting fluid concentration is an important parameter to ensure its performance, each cutting fluid has the best use concentration range, if the cutting fluid concentration Low and easy to cause problems such as corrosion of the workpiece and the machine, poor lubrication, etc., too high concentration will not only increase the production cost, but also reduce the ability to cool and flush the cutting, and will cause irritation to the operator and cause harm to the human body and the environment. .

However, the water-soluble cutting oil is an emulsion oil after adding water, which can balance the cooling and lubricating properties, and is most suitable for general metal processing, but the cutting tool of the processing tool uses the cutting fluid during the cutting process. The tropical travel between the cutting tool, the cutting and the workpiece to effectively reduce the cutting temperature, the thermal deformation of the workpiece and the cutting tool, and the moisture in the cutting fluid will start to generate oil and gas volatilization, resulting in the cutting fluid in the processing tool tank. The amount is decreased, and the concentration of the cutting fluid is too high, which affects the cooling and lubricating performance. Therefore, the operator needs to fill the cutting fluid of the processing tool tank at regular intervals, and the cutting fluid is formulated with a suitable concentration. The method of replenishing the fuel tank of each processing machine not only consumes labor and cost, but also has a low work efficiency, and the number of internal processing tools installed in a relatively large-scale factory is usually many, and the manual method is different for each. It is difficult to estimate the time and cost of the fuel tank of the processing machine for the oil replenishment, and it is not in line with the economic benefit. , That is, for those who engaged in this industry I want to study the direction of improvement.

Therefore, in view of the above-mentioned processing tools, the above-mentioned processing tools are used to check the amount of cutting fluid in the fuel tank and to supplement the cutting fluid. The collection of relevant materials has been evaluated and considered by many parties, and the trial and development experience of the industry has been continuously tried and modified. The invention patent for the design of such an automatic dosing system was born.

The main purpose of the present invention is to sense the height of the cutting fluid by using the liquid level control device inside the fuel tank of each processing machine. When the liquid level control device senses that the cutting fluid height is in the low position state, the automatic control is performed. The dosing system uses the pump and the electromagnetic valve to pump the cutting fluid in the fuel tank through the oil suction pipe to be pumped into each oil storage tank, and the water and the medicine are transmitted through the regulating pipeline by the pumping and the electromagnetic valve. According to the set time, the cutting fluids are sequentially circulated into the respective oil storage tanks, and the cutting fluids of the predetermined concentration are sequentially circulated, and each of the oil storage barrels respectively uses the pumping and matching electromagnetic valve to output the cutting fluid with a predetermined concentration through the oil feeding pipeline to the fuel tank. For oil replenishment, the automatic dosing system can automatically replenish the fuel tank of each processing machine, so as to save manpower, check the cutting fluid volume of the fuel tank and the labor and cost of filling the cutting fluid, and maintain the cutting fluid concentration. This improves the accuracy of the workpiece machining and extends the life of the cutting tool.
