Problems solved by technology

Composite pipes are generally connected by straight pipes, and the interface is currently mostly made of metal composite pipes, which are expensive and only used on small diameters.
The continuous fiber-reinforced plastic composite pipes that have been sold in the market are also connected with pure plastic composite pipe fittings, which can easily cause diameter reduction.
Therefore, there is no better interface method for the butt joint of composite pipes to reflect the characteristics of composite pipes.

Embodiment Construction

[0022] Such as Figure 1-3 As shown in one of them, the present invention is a pipe flanging device suitable for fiber composite pipes, which includes two symmetrically arranged movable frames 1, and the two movable frames 1 are respectively driven by corresponding mold clamping driving parts 3 to approach or close to each other. Move away from each other; the two movable frames 1 are respectively provided with mutually symmetrical forming molds 2, and the forming molds 2 include a semi-circular die 22 and a pressing plate 21, and the die 22 is fixed on the movable frame 1 on the corresponding side Above, the pressure plate 21 is connected to one axial end of the die 22 and is driven by the extruding driver 24 for extruding movement; the molding dies 2 on the two movable frames 1 are clamped and set on the pipe 5 to be flanged Finally, the two press plates 21 merge to form a complete ring, and the two dies 22 also merge to form a complete ring, and a complete ring-shaped flang...

Abstract

The invention discloses a pipe flanging device and method applicable to a fiber composite pipeline. The device comprises two movable frames which are symmetrically arranged; shaping molds are arrangedon the two movable frames respectively and are symmetrically arranged; the shaping molds comprise pressing molds and pressing plates which are all in a semi-annular shape; the pressing molds are fixed on the movable frames on the corresponding sides; the pressing plates are connected with axial ends of the pressing molds and are driven by squeezing driving members to make squeezing motion; the shaping molds on the two movable frames are closed and sleeve on a pipe to be flanged; the two pressing plates are combined into a complete annular shape; and the two pressing molds are combined into acomplete annular shape and a flanging cavity which is in a complete annular shape is formed between the two pressing molds. According to the device and method, the split shaping molds form flanging atthe opening of the pipe, feeding and discharging of the pipe are convenient, and effective positioning and flanging operation of the pipe can be realized; and the flanging shaping quality of the pipeis excellent, so the butt-joint cost of pipes can be effectively lowered, the construction difficulty is lowered and the butt-joint quality of the pipes is guaranteed.

Description

technical field [0001] The invention relates to the field of pipe flanging devices, in particular to a pipe flanging device and method suitable for fiber composite pipes. Background technique [0002] Fiber composite pipe has the characteristics of high heat resistance, high pressure resistance, light weight, non-corrosion, long life, designable and recyclable, and is the direction of pipeline development in the future. Composite pipes are generally connected by straight pipes, and metal composite pipe fittings are mostly used for the interface at present, which are expensive and only used on small diameters. The continuous fiber-reinforced plastic composite pipes that have been sold in the market are also connected with pure plastic composite pipe fittings, which can easily cause diameter reduction. Therefore, there is no better interface method for the butt joint of composite pipes to reflect the characteristics of composite pipes. Contents of the invention [0003] Th...
