Special drill for clothing formwork machine

Abstract

The invention discloses a special drill for a clothing formwork machine. The special drill for the clothing formwork machine is characterized by being formed by a drill body, a safety baffle and a drill handle through connection. The drill body is structurally integrally formed by a drill body front end part and a drill body main body. The drill body front end part is provided with a main cutting knife and an S-shaped cutting knife; a locating groove is formed at the position of the drill handle close to the tail end, and the safety baffle is structurally formed by two cylinders through connection. According to the drill, the main cutting knife, the S-shaped cutting knife, the safety baffle and a chip removal groove are effectively combined, the drilling strength of the drill is improved, and the discharging of chips is accelerated.

Description

technical field [0001] The invention belongs to the field of drill bits, in particular to a special drill bit for a garment template machine. Background technique [0002] A tool on a drill, drill press, or drilling machine that creates holes in a workpiece or rock. Xu Chi's "Goldbach's Conjecture Oil Head": "In 1956, the drilling materials in our country were a little tight, and the drill bits were not enough." During the work process, the drill bit rotates with the vertical shaft and moves axially at the same time. The soil is cut under the torque and axial force of the drill bit, and loosened under the extrusion and centrifugal force of the working blades, forming a soil flow that is pressed to the pit wall and lifted to the surface along the page. When the soil flow moves to the place where there is no pit wall, the broken soil is thrown around the pit due to the centrifugal force, and the digging process is completed. [0003] Drills are also needed in the field of cl...
