Blade type milling cutter

Abstract

The invention discloses a blade type milling cutter which comprises a clamping part, a blade seat and a milling cutter blade, wherein one end of the blade seat is connected with one end of the clamping part; a clamping groove is formed in the other end of the blade seat; the milling cutter blade is embedded into the clamping groove, and is fastened by fastening pieces; a first flowing liquid passage in the length direction is formed in the clamping part; two second flowing liquid passages are formed in the blade seat; one end of each second flowing liquid passage is communicated with the first flowing liquid passage, and the other ends of the second flowing liquid passages are arranged on the two inner sidewalls of the clamping groove; grooves are formed in the two sidewalls of the milling cutter blade, and are communicated with the two second flowing liquid passages respectively; the bottom ends of the grooves are positioned outside the clamping groove. According to the blade type milling cutter, the milling cutter blade is fixed on the blade seat by virtue of the fastening pieces, the grooves in which cooling liquid flows are formed in the two sides of the milling cutter blade, and when the blade type milling cutter is used, the two sides of the milling cutter blade can be cooled by the cooling liquid, so that the milling cutter blade is unlikely to damage, and the service life is prolonged.

Description

technical field [0001] The invention relates to a milling cutter, in particular to a blade type milling cutter. Background technique [0002] Milling machine is a processing tool mainly used for metal cutting. Milling machine drives the milling cutter to rotate and cuts metal with its milling blade. Therefore, the milling blade is easy to heat. In order to cool down, a tunnel is generally opened in the milling cutter. The coolant flows through the tunnel, which is generally opened directly inside the milling cutter, and the port is located at the lowest end. This structure cannot guarantee the complete cooling of the milling insert, and it is easy to cause damage to the milling insert. Contents of the invention [0003] In order to solve the above technical problems, the present invention provides a blade type milling cutter. [0004] In order to achieve the above object, the technical scheme adopted in the present invention is: [0005] A blade type milling cutter, comp...

AI Technical Summary

Problems solved by technology

[0002] Milling machine is a processing tool mainly used for metal cutting. Milling machine drives the milling cutter to rotate and cuts metal with its milling blade. Therefore, the milling blade is easy to heat. In order to cool down, a tunnel is generally opened in the milling cutter. There is medium-flow coolant in the tunnel. The tunnel is generally opened directly inside the milling cutter, and the port is located at the lowest end. This structure cannot guarantee the complete cooling of the milling cutter, and it is easy to cause damage to the milling cutter.
