Hardware product punching cooling drill bit

Abstract

The invention discloses a hardware product punching cooling drill bit comprising a drill body, a drill bit and a tail end. The drill bit and the tail end are connected to the two ends of the drill body correspondingly. A flow guide pipe is arranged in the drill body, and the two ends of the flow guide pipe are arranged in the drill bit and the tail end correspondingly. The two sides of the flow guide pipe are each connected with water drainage holes, and the water drainage holes are arranged in multiple sets at equal intervals. Internal supporting blocks are arranged inside the drill bit. Reset springs are connected between the internal supporting blocks and the flow guide pipe. Rotating shafts are arranged at the two ends in the tail end correspondingly. One side of each rotating shaft isconnected with a supporting rod, and one end of each supporting rod is connected with a fixed disc. According to the hardware product punching cooling drill bit, by arranging the fixed discs at the tail end, auxiliary fixation can be achieved for the drill body and a drive structure when the drill body and the drive structure are installed, each supporting rod connected with one side of the corresponding fixed disc is used as a supporting structure and can be subjected to angle regulation through the corresponding rotating shaft, and opening and closing control during installation and fixation is achieved.

Description

technical field [0001] The invention relates to a drill bit, in particular to a drilling cooling drill bit for hardware products. Background technique [0002] Hardware products refer to auxiliary and accessory finished products used in daily life and industrial production. In the early days, they were mostly made of metal materials such as gold, silver, copper, iron, and tin, hence the name. In addition to the use of various metal materials, non-metallic materials such as plastics and glass fibers are also widely used. The hardware products industry plays an important role in improving people's living standards, improving the quality of life, and continuously meeting the people's growing material and cultural needs. Market demand and the employment of labor force have played a positive role in accelerating the pace of industrialization and urbanization. When processing hardware products, it is often necessary to drill holes, and the drilling tools need to use cooling drills...
