Description

TECHNICAL FIELD

[0001] The utility model relates to the field of tapping, and particularly to a tapping cooling mechanism. BACKGROUND

[0002] The tapping machine is a kind of mechanical processing equipment for machining internal thread, screw or called tooth buckle on the inner side of the hole of various parts with different specifications of through hole or blind hole such as machine shell, equipment end face, nut and flange plate.

[0003] During the actual tapping process of the tapping machine, lubricating oil needs to be added, and the purposes are as follows:

[0004] 1. Cooling. When the tap is cutting, the temperature of the tap rises sharply. If not cooled, the tap is easy to burn out, which leads to a sharp decrease in the strength of the tap and affects the durability of the tap.

[0005] 2. Lubrication. If no oil is added when the tap is cutting, the thread surface cut out is easy to appear rough and not smooth, which seriously affects the quality of the thread.

[0006] 3. Chip removal. During the tapping process, a large amount of iron chips (mainly cutting taps) are produced. The iron chips are easy to stick to the inside of the thread hole and the tap. At this time, the tapping oil with good permeability is required to remove the machining chips, that is, the chip removal property is good.

[0007] However, the cooling of the conventional tapping machine mostly adopts the cooperation of flowing lubricating oil and filter screen. The lubricating oil is sprayed to realize the lubrication, cooling and chip removal of the workpiece. The chips after chip removal are easy to accumulate on the surface of the filter screen, which leads to the accumulation of more chips during the long-term application of the filter screen. However, since the conventional filter screen is flat, the accumulation of chips is relatively scattered, which leads to the inconvenience of cleaning the messy chips. Therefore, we improve it and propose a tapping cooling mechanism. CONTENT OF THE UTILITY MODEL
