Automatic pipe orifice butt-joint pipe contracting device

Abstract

The invention belongs to the technical field of mechanical equipment, and particularly discloses an automatic pipe orifice butt-joint pipe contracting device. The device comprises a driving device, apipe and a fixed seat, wherein a heating element is arranged in the fixed seat, the outer side of the heating element is wrapped with a heat-insulating and pressure-resisting part, the driving deviceis connected with an automatic part taking device, an automatic extruding device and an automatic heating device, the automatic part taking device comprises a mechanical arm, a lifting device, a moving device and a servo mechanism, wherein the mechanical arm is used for grabbing the pipe, the automatic extruding device is arranged around the heat-insulating and pressure-resisting part, and the automatic heating device comprises a heater, a high-temperature detector, a relay and the heating element, wherein the heater, the high-temperature detector, the relay and the heating element are connected through wires to form a closed-loop structure. When the device is adopted for contracting a pipe orifice, the pipe orifice can be automatically and accurately in butt joint with the heating element, the pipe orifice of the elbow pipe can be rapidly contracted, so that the hard elbow pipe can be effectively prevented from being extruded and broken, the time and the labor are saved, the stabilityis extremely high, and the machining success rate is improved.

Description

technical field [0001] The invention relates to the technical field of mechanical equipment, in particular to an automatic nozzle butt joint shrinking device. Background technique [0002] Pipe fittings are widely used in the automotive field. Whether it is a bellows, manifold, or the nozzles at both ends of the connecting pipe must be connected to other parts. If the connecting nozzle of the pipe fitting is too small, there will be gaps in the connecting part, which cannot reach seamless connection requirements. [0003] In CN201710060386.9, an invention patent named nozzle processing device is disclosed. The patent includes a shrinking and expanding die. The shrinking and expanding die includes an inner mold composed of several inner petal molds. The outer mold composed of the set outer valve mold is used to respectively realize the radial expansion and contraction of the inner mold and the driving device for the radial expansion and contraction of the outer mold.

AI Technical Summary

Problems solved by technology

[0004] The above-mentioned patents use manpower to place too small pipe fittings in the shrinking and expanding die. Although the shrinkage of the pipe mouth can be realized through the driving device, if the material of the pipe mouth is too hard, the shrinking speed of the pipe fittings is very slow or even does not shrink. The process of violent extrusion It is also easy to cause the nozzle of the pipe fitting to break. When the pipe fitting is artificially put into the shrinking and expanding die, experienced producers are required to achieve precise docking. Once the deviation occurs, the nozzle is prone to deformation during the shrinking process.
