High-performance high-speed steel drilling equipment

Abstract

The invention discloses high-performance high-speed steel drilling equipment which comprises a box body. A single door is hinged to the front face of the box body, and a telescopic rod is arranged at the top of the inner wall of the box body. By arranging a water spraying mechanism, the equipment can move along with a drilling device without manual movement and adjustment of workers; by arranging first fixing plates, on one hand, the size of an opening for water flow spraying can be limited, the water flow spraying effect can be achieved, a drill bit can be better cooled, on the other hand, when water spraying is not carried out, the opening of a water pipe can be closed, the situation that a water pipe opening is blocked due to too much dust can be reduced, the service life of the drill bit can be prolonged through water spraying cooling, and the condition that breakage occurs due to high temperature is reduced; and by arranging a bent rod, the contraction distance of the two first fixing plates can be limited when water flow impact exists, and the two first fixing plates can be rebounded to the original positions through small springs when no water flow impact exists.

Description

technical field [0001] The invention relates to the technical field of high-speed steel, in particular to a high-performance high-speed steel drilling equipment. Background technique [0002] High-speed steel (HSS) is a tool steel with high hardness, high wear resistance and high heat resistance, also known as high-speed tool steel or front steel, commonly known as white steel; high-speed steel has good process performance, good strength and toughness , so it is mainly used to manufacture complex thin blades and impact-resistant metal cutting tools, as well as high-temperature bearings and cold extrusion dies. In addition to the high-speed steel produced by smelting, powder metallurgy high-speed steel appeared after the 1960s. Its advantage is that it avoids the reduction of mechanical properties and heat treatment deformation caused by carbide segregation caused by smelting production; [0003] However, when the current drilling equipment is performing drilling work, the h...

Problems solved by technology

[0003] However, when the current drilling equipment is performing drilling work, the high-speed rotation of the drill bit will cause the temperature of the drill bit to rise, and the temperature rise of the drill bit will easily cause damage. Therefore, it is necessary to spray water on the drill bit when it is working, so as to achieve cooling. effect, but the general water spray device cannot move with the drilling equipment, and the staff needs to manually move it to a suitable position, which is very inconvenient. For this reason, we propose a high-performance high-speed steel drilling equipment
