Description

Technical Field

[0001] This utility model relates to the field of pipe processing technology, specifically a pipe flanging heating and shaping device. Background Technology

[0002] The existing pipe flanging device is equipped with a heating mechanism and a pipe flanging positioning plate. First, the end of the pipe is heated by the heating mechanism, and then the pipe is moved by the driving mechanism so that the end of the pipe abuts against the pipe flanging positioning plate. Under the continued push of the driving mechanism, the end of the pipe is flanged.

[0003] The shortcomings of this structure are: there is no radial limiting mechanism, the outer diameter of the pipe after flanging is uncontrollable, the outer diameter after flanging depends entirely on the fluidity of the pipe material and the magnitude of the thrust, and it cannot be actively constrained, resulting in poor dimensional consistency of batch pipes; and the flanging is prone to problems such as flared deformation or uneven edge thickness. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a pipe flanging heating and shaping device with simple structure, good flanging limiting effect, and high consistency of flanging size.

[0006] The flange forming mechanism of this utility model also includes a guide post, which is fixed at the center of the forming groove. When the end of the tube is pressed into the forming groove, the guide post can be inserted into the inner hole of the tube to guide it, achieve radial centering and positioning, and ensure the concentricity of the tube and the forming groove. At the same time, the axial guidance of the guide post can prevent the tube from deflecting or misaligning during the flange forming process, thereby ensuring the uniformity of wall thickness and dimensional accuracy after flange forming.

[0007] The length of the guide post described in this utility model is greater than the depth of the shaped circular groove; The guide post adopts a conical or frustum-shaped structure. The large-diameter end of the guide post is fixed in the shaping circular groove, and the small-diameter end faces the pipe. The length of the guide post is set to ensure that the pipe is centered when it is initially inserted. The conical or frustum-shaped structure guides the pipe.

[0008] The flange shaping mechanism of this utility model is mounted on a support plate; The flanging and shaping mechanism also includes a screw and a nut, wherein the screw is axially fixed on the end face of the shaping mold away from the shaping groove; The support plate has a screw through hole, through which the screw passes and is threadedly connected to the nut for locking and fixing; thus, the flanging and shaping mechanism is stably fixed on the support plate.

[0009] The support plate of this utility model is fixed with a positioning plate. The positioning plate has a second positioning groove and a second screw through hole that are connected.

The guide heating column extends into the inner hole of the pipe to heat the end of the pipe. The guide heating column can both heat the pipe to facilitate later shaping and position the pipe.

[0011] The guide heating column of this utility model adopts a conical or frustoconical structure, with the small-diameter end of the guide heating column facing the pipe; it can guide the pipe, and at the same time, the large-diameter end of the guide heating column has a large cross-sectional area and high heat capacity, which can concentrate heat to quickly soften the end of the pipe (flared area), while the heat at the small-diameter end decreases, avoiding excessive heating of the non-flared area of ​​the pipe.

[0012] The heating mechanism described in this utility model is mounted on a support plate; The heating mechanism also includes a heat insulation sleeve, which has an internal thread. The heating head further includes a positioning section and a connecting section.

The positioning section is inserted into the positioning groove one, and the connecting section passes through the heat insulation perforation and the heating head perforation and is threadedly connected to the heat insulation sleeve. The heat insulation sleeve abuts against the support plate. The heating mechanism is provided with several intervals on the heat insulation plate; The insulation panel can insulate multiple heating mechanisms and support plates, preventing heat conduction.

[0014] The heat insulation plate of this utility model includes a front section and a rear section. The outer diameter of the front section is larger than that of the rear section. A heat insulation limiting surface is formed between the front section and the rear section. The rear section is inserted into the heating head through hole of the support plate, and the heat insulation limiting surface abuts against the support plate, thereby further achieving heat insulation of the support plate.

[0015] The beneficial effects of this utility model are as follows: the setting of the shaping groove restricts the outer diameter and thickness of the pipe after flanging. Under the constraint of the shaping groove, the pipe end forms a flanging structure with consistent outer diameter and uniform thickness. The structure is simple and ensures the consistency of the pipe flanging size. Attached Figure Description
