Description

Technical Field

[0001] The present invention relates to the field of milling cutter production, and particularly to a temperature reduction system for the production of metal cutting milling cutters. Background Art

[0002] A milling cutter is a rotating tool with one or more cutting teeth used for milling. During operation, each cutting tooth intermittently cuts off the surplus of the workpiece in turn. Milling cutters are mainly used for machining planes, steps, grooves, formed surfaces and cutting workpieces on milling machines. The processing and production of conventional milling cutters are carried out by a mother milling machine to perform spiral milling on the milling cutter blank, cutting out chip removal grooves and the positions of the cutter heads. During the milling operation, the milling cutter rotates at a high speed. In the production process of existing milling cutters, it is also necessary to mill chip removal grooves on the rough blank of the milling cutter through the milling process, and at the same time, cooperate with the flow of refrigerant to contact the milling area to reduce the temperature, which belongs to the cooling and temperature reduction operation for the production of milling cutters in the milling process. Among them, in the existing milling process, the milling cutters in the production and processing preparation device have a variety of different cooling methods, such as directly spraying and cooling the milling cutters in the preparation device through an external spraying system, and the milling cutters in the preparation device have internal flow holes connected to the milling cutter mounting chuck in the preparation device, and directly pressurize and transport the refrigerant from the inside to the outside for cooling treatment.

[0003] The existing external spraying temperature reduction system usually simply filters the doped metal chips through simple filtration, and cooperates with components such as pump machines for recycling. However, for the internal flow cooling preparation device, simple filtration treatment is likely to cause wear and blockage to the internal parts of the preparation device. Therefore, it is particularly important to propose a temperature reduction system for the production of metal cutting milling cutters that is suitable for external spraying and internal flow cooling. In view of this, we propose a temperature reduction system for the production of metal cutting milling cutters. Summary of the Invention

[0004] The purpose of the present invention is to overcome the deficiencies of the prior art, adapt to the actual needs, and provide a temperature reduction system for the production of metal cutting milling cutters to solve the technical problem that the current temperature reduction system for the production of metal cutting milling cutters has insufficient filtration and cannot meet external spraying and internal flow cooling.

Among them, the body mechanism, the secondary filtering mechanism, the auxiliary mechanism, and the combined mechanism form a circulating filtering structure. Among them, the outside of the opposing mechanism and the liquid inlet cavity form a cooling circulation structure. The present invention sets the body mechanism and the secondary filtering mechanism to perform rough filtering and secondary filtering on the used refrigerant, thereby reducing the impurity content of the refrigerant, enabling the refrigerant to be fully used, and at the same time reducing the wear of the large-particle impurity waste chips contained in the refrigerant on the components of the two cooling operations inside and outside the cooling system, resulting in liquid leakage, and assisting in improving the service life.

At the same time, the movement of the connecting block makes the convex top port away from the one-way sealing cavity. At this time, the external flow cooling channel is closed, and the driven bevel gear A and the driven bevel gear B are rotated relatively by reversely rotating the driving bevel gear, driving the threaded link A and the threaded link B to rotate relatively, moving the connecting block to make the convex top port close to the one-way sealing cavity, using the convex top port to push the sealing block, so that the sealing block is separated from the small end of the one-way sealing cavity, making the combined mechanism communicate with the liquid inlet cavity. At the same time, the internal flow connecting groove of the connecting block close to the connecting block is completely separated from the liquid inlet cavity.
