Circulating cooling type multi-blade milling cutter

Abstract

The invention discloses a circulating cooling type multi-blade milling cutter. The circulating cooling type multi-blade milling cutter comprises first grooves, a fixed sleeve, a water injection hole,a cover, a handle, blades, second grooves, a cutter body, a first water tank, second water tanks, connecting rods, fixing boxes, valves, limit blocks, pistons, mercury chambers and steel wire ropes. The blades are evenly arranged on the surface of the cutter body, and thus the working efficiency is high; the first water tank is arranged inside the cutter body and connected with the second water tanks, the fixing boxes are arranged inside the second water tanks, and the mercury chambers are formed inside the fixing boxes; the blades generate heat, the temperature is increased, mercury expands and upwards pushes the pistons, and the top connecting rods of the pistons upwards push the limit blocks; the two ends of the limit blocks are fixedly connected with the steel wire ropes, the steel wire ropes open the valves, the valves are opened, water inside the first water tank flows into each second water tank, and thus the multiple blades are cooled, so that the service life of the milling cutter is prolonged; and the second grooves are formed in the surface of the handle, fixing is facilitated, the overall structure is compact, the time and labor are saved, and the efficiency is high.

Description

technical field [0001] The invention relates to a milling cutter, in particular to a circulating cooling multi-blade milling cutter, which belongs to the technical field of mechanical equipment applications. Background technique [0002] A milling cutter is a rotating tool with one or more teeth for milling. When working, each knife tooth cuts off the allowance of the workpiece intermittently in turn. Milling cutters are mainly used for machining planes, steps, grooves, forming surfaces and cutting off workpieces on milling machines. A narrow margin is ground on the flank to form a relief angle. Due to the reasonable cutting angle, its life is relatively high. The tooth back of the sharp-tooth milling cutter has three forms: straight line, curved line and broken line. Straight backs are often used for fine-toothed finishing milling cutters. The teeth with curved and broken line tooth backs have better strength and can withstand heavy cutting loads, and are often used in ...

Problems solved by technology

[0003] However, the current milling cutters are all cooled by lubricating oil and cannot be cooled by themselves. When the working hours are long, the blades of the milling cutters will heat up and easily cause the milling cutters to break, which wastes resources and reduces work efficiency, and the existing milling cutters have fewer blades. The work efficiency is low, which is not conducive to the processing of the production process
