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

Abstract

The invention discloses an automatic machining method and equipment of a small diameter copper pipe with an inner cone and an outer cone and a thin-wall circle. The automatic machining equipment of the small diameter copper pipe with the inner cone and the outer cone and the thin-wall circle comprises corollary equipment, a spinning pipe inner cone actuating mechanism, a spinning pipe outer cone integral type spinning cone mould, a mould cleaning rotating head and a pipe feeding and discharging device. The corollary equipment comprises a spindle box, a horizontal guiding rail, a longitudinal guiding rail, a sliding table and a servo motor. The spinning pipe inner cone actuating mechanism comprises a tapered mandrel component on a fixed sliding block in an oblique sliding block component and a driving air cylinder of the tapered mandrel component. The spinning pipe outer cone integral type spinning cone mould is arranged on a water cooled base. The mould cleaning rotating head is connected with a shaft of a stepper motor. The pipe feeding and discharging device comprises a feeding mechanism and a discharging mechanism. The cleaning rotating head and a nozzle of an integral type spinning cone mould inner cone and a material receiving box of the pipe are installed on a spindle box body of the equipment. The automatic machining method and the equipment of the small diameter copper pipe with the inner cone and the outer cone and the thin-wall circle has the advantages that the structure is reasonable and simple, the operation is convenient, the spinning inner cone and outer cone quality is good, the method of drilling, precision boring and mandrel-free finishing turning machining the thin-wall circle improves the uniformity of the wall thickness. The automatic machining is high in efficiency and low in cost.

Description

technical field [0001] The invention belongs to a small-diameter copper tube processing device, in particular to an automatic processing method and equipment for small-diameter copper tubes 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, ...

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
