Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of non-ferrous metal processing, and more particularly to a drilling equipment for non-ferrous metal processing. BACKGROUND

[0002] Due to the characteristics of non-ferrous metals, such as soft texture, high thermal conductivity, strong plastic deformation ability, and easy sticking to the tool, the drilling process has significant differences in equipment requirements, which also leads to the gradual exposure of technical limitations of traditional drilling equipment when adapting to non-ferrous metal processing.

[0003] According to the processing requirements, the batch, precision, and hole size of non-ferrous metal drilling equipment are mainly divided into bench drilling machines, vertical drilling machines, and special drilling machines. The structural design of various types of equipment is focused on reducing sticking, controlling deformation, and improving efficiency.

[0004] Among them, the core advantages of vertical drilling machines are strong structural rigidity, high drilling precision, flexible processing range, and stable feed control, but they face high costs and complex operation thresholds.

[0005] The existing vertical drilling machines still have many shortcomings. Non-ferrous metals have very high thermal conductivity. During drilling, the frictional heat between the tool and the workpiece will quickly conduct to the inside of the workpiece, causing the local temperature of the workpiece to rise, which easily leads to thermal expansion and contraction deformation of the workpiece.

[0006] Due to the generation of cutting chips during processing, the cutting chips are easily squeezed between the hole wall and the tool. Traditional chip removal methods such as natural falling and compressed air blowing chips cannot efficiently remove the cutting chips, which easily causes hole wall scratches, hole diameter blockage, and even tool chipping. In addition, the flying cutting chips can cause harm to people and workpieces.

[0007] If the clamping force is insufficient or there is a gap between the workpiece and the clamp in the traditional workpiece fixing method, the cutting force of the tool during processing will cause the workpiece to shake, resulting in rough hole walls, tool chipping, and reduced depth size precision.

[0008] In summary, there is an urgent need for a non-ferrous metal processing drilling equipment that can easily collect cutting chips and accurately fix the workpiece. SUMMARY
