Broken metal filing filtering and collecting device

Abstract

The invention discloses a broken metal filing filtering and collecting device. The broken metal filing filtering and collecting device comprises a water tank which is open at the upper part and used for containing cooling liquid, wherein water baffles are arranged in the water tank longitudinally, and the heights of the water baffles are lower than that of a side wall of the water tank. The water tank is placed at the bottom of a machining center or a machine tool; the cooling liquid flows from the machining center or the machine tool into the water tank; the cooling liquid consists of water and lubricating oil, and the density of the cooling liquid is far smaller than that of iron filings, so that the iron filings can sink at the bottom of the water tank first, and are adsorbed by strong magnets in a sinking process; in a process that the cooling liquid flows towards the tail of the water tank, due to an effect of the first water baffle, the cooling liquid with low density and light specific gravity flows through the upper parts of the water baffles, and the iron filings with larger sizes are intercepted at the first water baffle, so that separation and collection of the iron filings and the cooling liquid are achieved; the filtered cooling liquid can be repeatedly used for cooling after pumped by a water pump; and the circulation can ensure that all the cooling liquid used for the cooling is clean cooling liquid free of machining broken metal filings.

Description

technical field [0001] The invention relates to an auxiliary chip filtering and collecting device for machine tools and machining centers. Background technique [0002] In large machine tools and machining centers, the tool head will generate heat due to friction during machining, so a coolant mixed with lubricating oil and water is used for cooling. Usually, the coolant is recycled, and the iron filings generated during the machining process are continuously mixed into the coolant. Since it is difficult to separate and clean up, the coolant becomes more and more dirty, and the coolant containing a large amount of iron filings will Scratches are left on the tool and the workpiece to be processed, affecting the processing quality and work efficiency. However, if the coolant is replaced frequently, it will not only increase the processing cost and reduce the processing efficiency, but also waste the coolant and cause waste and pollution. There are also ways to filter the iro...

Problems solved by technology

Usually, the coolant is recycled, and the iron filings generated during the machining process are continuously mixed into the coolant. Since it is difficult to separate and clean up, the coolant becomes more and more dirty, and the coolant containing a large amount of iron filings will Scratches are left on the tool and the workpiece to be processed, affecting the processing quality and work efficiency

However, if the coolant is replaced frequently, it will not only increase the processing cost and reduce the processing efficiency, but also waste the coolant and cause waste and pollution

There are also ways to filter the iron filings in the cooling liquid by means of filter screen filtration, but in the existing actual operation, some small metal powders such as iron filings are difficult to be filtered out, resulting in incomplete filtration and affecting the processing work.
