Automatic processing equipment for small-diameter copper tubes with inner and outer cones and thin-walled circles

Abstract

The invention discloses automatic processing equipment for a small-diameter copper pipe with inner and outer cones and a thin-wall cylinder. The automatic processing equipment comprises matched equipment, a pipe inner cone spinning executing mechanism, an integral cone spinning die for spinning a pipe outer cone, a die washing swivel head and a pipe loading and unloading device, wherein the matched equipment comprise a spindle box, a transverse guide rail, a longitudinal guide rail, a sliding carriage and a servo motor; the pipe inner cone spinning executing mechanism comprises a tapered spindle assembly and a driving motor thereof, and the tapered spindle assembly is arranged on a fixed slider in an oblique slider assembly; the integral cone spinning die for spinning the pipe outer cone is arranged on a water-cooling base; the die washing swivel head is connected with a stepper motor shaft; the pipe loading and unloading device comprises a loading mechanism and an unloading mechanism; an inner cone washing swivel head of the integral cone spinning die, an oil nozzle and a pipe collecting box are mounted on the spindle box body of the equipment. The automatic processing equipment is reasonable and simple in structure and convenient to operate, spins the inner and outer cones at high quality, improves the wall thickness evenness by the methods of drilling, precise boring and non-spindle thin-wall cylinder finish turning, is high in automatic processing efficiency and is low in cost.

Description

technical field [0001] The invention belongs to a processing device for small-diameter copper pipes, in particular to an automatic processing device for small-diameter copper pipes with inner and outer cones and thin-walled circles. Background technique [0002] Small-diameter copper pipe fittings with inner and outer cones and thin-walled circles used in some industrial productions have a diameter of about Φ5, a wall thickness of about 0.6mm, and a length of about 50mm. The processing technology of copper pipe fittings is strict. Due to the small diameter of small-diameter copper pipe fittings, it is difficult to control the shape of the inner cone if the conventional spinning cone method is used. The axial resistance of the integral oil-free conical cone mold is large when spinning, and it is easy to pile up the inside and outside of the pipe fittings. Waste products, short service life; if a conventional centered shaft is used to turn small-diameter thin-walls, it is eas...

Problems solved by technology

Due to the small diameter of small-diameter copper pipe fittings, it is difficult to control the shape of the inner cone if the conventional spinning cone method is used. The axial resistance of the integral oil-free conical cone mold is large when spinning, and it is easy to pile up the inside and outside of the pipe fittings. Waste products, short service life; if a conventional centering shaft is used to turn small-diameter thin-walls, it is easy to produce uneven wall thickness
