Drilling device convenient to cool for metal product machining

Abstract

The invention relates to a drilling device convenient to cool for metal product machining. The drilling device comprises a base, a machining device, a fastening mechanism, a lifting mechanism, a lifting plate and two supporting plates. The machining device comprises an air cylinder, a seal cover, an electric motor, a drilling rod, a cooling mechanism and a seal mechanism. The seal mechanism comprises an air bag, an air inflation box, an air inlet pipe, and a gas conveying pipe, and the cooling mechanism comprises a cooling box, a cooling pipe, a cooling pipe, a seal plug, a ceramic block, a water pump, a backflow pipe and an absorbing pipe. According to the drilling device convenient to cool for metal product machining, through the seal mechanism, the seal cover seals a machining part on the upper surface of a workpiece, concentrated chippings can be cleaned while the chippings are prevented from being splashed, through the cooling mechanism, cooling liquid enters the seal cover, and makes contact with the workpiece and the drill rod for cooling, through backflow, consumption of cooling liquid is reduced, the ceramic block is used for absorbing heat, the cooling liquid is cooled, the cooling effect on the workpiece and the drill rod can be improved, and the device practicability is improved.

Description

technical field [0001] The invention relates to the field of metal product processing equipment, in particular to a drilling device for metal product processing that is convenient for cooling. Background technique [0002] Drilling machine is a general term for machinery and equipment that uses a tool that is harder and sharper than the target to leave a cylindrical hole or hole on the target by means of rotary cutting or rotary extrusion. Also known as punching machine, drilling machine, through hole machine and so on. The desired effect is achieved by drilling precision parts. [0003] When the existing drilling machine is drilling metal products, the surface temperature of the drill rod and the workpiece will rise due to the high-speed rotation of the drill rod, which will affect the service life and processing accuracy of the drill rod. The coolant is sprayed at the position, and the heat is absorbed and cooled by the coolant. However, due to the high-speed rotation of...

Problems solved by technology

[0003] When the existing drilling machine is drilling metal products, the surface temperature of the drill rod and the workpiece will rise due to the high-speed rotation of the drill rod, which will affect the service life and processing accuracy of the drill rod. The coolant is sprayed at the position, and the heat is absorbed and cooled by the coolant. However, due to the high-speed rotation of the drill pipe, it is easy to throw the coolant out, making it difficult for the coolant to contact the high-temperature drill pipe and workpiece, making the heat dissipation effect worse. At the same time, During the rotary drilling process of the drill pipe, splashing debris is also prone to be generated, which not only affects the safety of production, but also affects the cleaning of the equipment. The debris splashes everywhere, and the cleaning is extremely troublesome, resulting in the reduction of the practicability of the existing drilling equipment.
