Abstract

The invention provides a U-shaped driller for drilling a multilayer plate and relates to the technical field of a drilling tool. The U-shaped driller comprises a power head and a drilling rod, wherein the power head is mounted on the drilling rod; a first U-shaped blade slot and a second U-shaped blade slot are arranged on the power head; the U-shaped driller is characterized in that a first main cutting blade and a balancing blade are mounted on the first U-shaped blade slot; a second main cutting blade and a third main cutting blade are mounted on the second U-shaped blade slot; and cooling devices are arranged on the first U-shaped blade slot and the second U-shaped blade slot. The U-shaped driller has the beneficial effects that: the working efficiency of the U-shaped driller is greatly increased by adjusting the angles between the blades and cutter bars, the simultaneous drilling for a multilayer sheet is realized, and the use ratio of the blades is greatly increased by additionally arranging the balancing blade on the U-shaped blade slot.

Description

technical field [0001] The invention relates to the technical field of drilling tools, in particular to a U-drill for drilling multi-layer boards which can simultaneously drill multi-layer thin boards and improve the utilization rate of blades. Background technique [0002] In the traditional machining of hole systems, twist drills and group drills can be widely used in radial drills, vertical drills, multi-spindle combined drilling machines, and even hand electric drills because of their simple structure and low cost. However, with the rapid development of modern mechanical processing to high-speed, high-efficiency, and composite processing, the drilling of composite materials and materials that are difficult to process such as high hardness and high strength has been fundamentally changed due to the invention of the U drill. U-drill is the best drilling tool for drilling. Compared with twist drill, the advantages of U-drill are: 1. The processing efficiency is at least 2-3...
