Detailed Description
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
Referring to fig. 1-3, a 4-edge progressive slot milling cutter with an inner cooling hole comprises a milling cutter body 1 made of stainless steel, and a nanometer superhard coating is further arranged on the outer side of the milling cutter body 1 to ensure the hardness of the milling cutter body 1, wherein four groups of cutting edges are fixed on the outer wall of the milling cutter body 1, and an antirust coating is arranged on each cutting edge to improve the service life of the cutting edge and reduce the possibility of rust in the cooling process.
The inside of milling cutter main part 1 has been seted up coolant liquid passageway 2, the tip of coolant liquid passageway 2 is equipped with delivery port 3, delivery port 3 sets up two sets of in this embodiment, wherein a set of delivery port 3 sets up between the cutting edge, when milling, the coolant liquid in coolant liquid passageway 2 is spouted from between the cutting edge, its main effect is milling cutter when drilling, because milling cutter main part 1 stretches into in the work piece, traditional cooling mode is difficult to directly act on in the processing position, the condition that the temperature is too high appears easily, and through above-mentioned technical scheme, when then drilling, the coolant liquid is spouted from the side of milling cutter main part 1 and is directly acted on the work piece, can effectively avoid above-mentioned problem.
The other group of water outlets 3 are arranged at the bottom of the milling cutter body 1, and are sprayed out from the bottom of the milling cutter body 1 when milling is performed, the cooling liquid channel 2 can cool the inside of the milling cutter body 1 when cooling liquid is output, and the cooling liquid sprayed out from the bottom can blow away scraps generated on a workpiece and cool the workpiece.
In the actual external cooling process, in order to ensure that the milling cutter body 1 in the rotating process is not affected, a certain distance is reserved between the cooling spray nozzle and the milling cutter body 1, in order to ensure the cooling effect and the cooling range, the cooling spray nozzle is sprayed in a scattering mode in the water spraying process, one part of the cooling spray nozzle is sprayed on a workpiece and the milling cutter, and the other part of the cooling spray nozzle is directly wasted, so that a circular ring 5 is fixed on the outer side of the top of the milling cutter body 1, a plurality of connecting pipes 4 are fixed on the circular ring 5, the plurality of connecting pipes 4 are arrayed in a circle mode by taking the axis of the circular ring 5 as the circle center, one end of each connecting pipe 4 is connected in the cooling liquid channel 2, and the other end of each connecting pipe faces the bottom of the milling cutter body 1.
Through the above technical scheme, the coolant in the coolant channel 2 can enter into the connecting pipe 4 to spout from connecting pipe 4 bottom, the coolant of blowout is the scattering form this moment too, and a part is direct to be acted on milling cutter main part 1, cools off milling cutter main part 1, and clear up the sweeps that adhere to on the milling cutter main part 1 simultaneously, and another part can spray on the work piece, cools off the work piece, can realize inside and outside cooling in step through the effect of connecting pipe 4, and direct action is on milling cutter main part 1 and work piece in the outer cooling process, and is comparatively accurate, can not cause a large amount of waste of coolant.
