Embodiment Construction

[0024] It will be described in detail below in conjunction with specific embodiments according to the accompanying drawings.

[0025] like figure 1 , 2 The shown device for reducing the aperture of an elbow includes a driving device (50), an elbow 1, and a fixing seat 2. A heating element 8 is arranged inside the fixing seat 2, and the outside of the heating element 8 is wrapped with a heat-insulating and pressure-resistant component 4. The driving device is connected with an automatic heating device and an automatic extruding device 9, and the automatic extruding device 9 is arranged around the heat-insulating and pressure-resistant component 4;

[0026] The automatic heating device comprises a heater 5, a high temperature detector 6, a relay 7 and a heating element 8 connected by wires to form a closed-loop structure;

[0027] The fixing seat 2 is provided with a through hole, and there are 6 or more heating elements 8 with a fan-shaped cross-section that can move toward t...

Abstract

The invention belongs to the technical field of mechanical equipment, and particularly discloses a device for reducing the pore diameter of an elbow. The device comprises a driving device, the elbow and a fixing seat, wherein a heating element is arranged in the fixing seat, an automatic heating device and an automatic extruding device are connected to the driving device, the automatic extruding device is arranged on the periphery of a heat insulating and pressure resisting component; the automatic heating device comprises a heater, a high-temperature detector, a relay and a 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; and a through hole is formed in the fixing seat, and six or more than six heating elements which can move towards the axis and are fan-shaped are arranged in the through hole. According to the device, when the pipe orifice of the elbow is reduced, the pipe orifice of the elbow can be quickly reduced, the hard elbow is effectively prevented from being extruded and broken, and the processing success rate is improved.

Description

technical field [0001] The invention relates to the technical field of mechanical equipment, in particular to a device for machining holes. Background technique [0002] Elbows are widely used in the automotive field. Whether it is bellows, manifolds, or the nozzles of connecting pipes, they must be connected to other components. The gap cannot meet the requirements of seamless connection. [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. [0004] Although the above-mentioned patent can realize the shrinkage of the nozzle through the driving device, if the material of ...
