Description

Technical Field

[0001] The utility model belongs to the technical field of pipe fitting processing, and in particular relates to a drilling machine for processing stainless steel pipe fittings. Background Art

[0002] A drilling machine for processing stainless steel pipe fittings is a machine tool that uses a drill bit to process holes in stainless steel materials. The drilling operation of stainless steel pipe fittings is achieved through the rotation and axial movement of the drill bit. However, due to the high hardness and high cutting force of stainless steel in the existing technology, the drill bit and the stainless steel material rub against each other to generate high temperature during the drilling process, and the chromium element in stainless steel will also generate chromate when rubbing against the drill bit, further causing severe wear of the drill bit.

[0003] Application number "CN201020220655.7" describes a "CNC drilling machine for processing pipe fittings, wherein a spindle rotating device and a transmission guide device are provided on the upper portion of the bed, a drilling platform and a clamping tailstock are movably provided on the transmission guide device; a pipe wall clamping assembly and a drilling assembly are provided on the drilling platform, a pipe end clamping chuck is provided on the spindle rotating device and the clamping tailstock, and the spindle rotating device is further provided with a motor for driving the spindle and chuck to rotate."

[0004] The patented CNC drilling machine for pipe processing can process various metal and non-metal pipes of various specifications, with a wide processing range and good applicability.

[0005] The above patent can process various metal and non-metal pipes of various specifications, with a large processing range and good applicability. The utility model adopts PLC numerical control programming, which can automatically, efficiently, conveniently and safely process the through-holes on the outer wall of pipe fittings. However, the above drilling machine cannot replace the drill bit when the drill bit is worn out after long-term use. Because of the high hardness and high cutting force of stainless steel, the friction between the drill bit and the stainless steel material generates high temperature during the drilling process, and the chromium element in stainless steel will also generate chromate when rubbing against the drill bit, which further causes serious wear of the drill bit. It is also inconvenient to collect and process the debris dropped during the processing of pipe fittings, resulting in a large overall limitation of the drilling machine. Utility Model Content
