Description

Technical Field

[0001] This utility model relates to an automatic flanging device for ultra-high molecular weight polyethylene pipes, belonging to the field of polymer pipe flanging. Background Technology

[0002] Ultra-high molecular weight polyethylene (UHMWPE) is a thermoplastic resin that softens when heated and hardens when cooled, without undergoing any chemical reaction. This property is maintained regardless of repeated heating and cooling cycles. Based on this characteristic, existing UHMWPE pipe flanging devices have been designed. These devices soften the pipe ends through hot melting, and then use an extrusion flanging die to fold and press the edges, completing the flanging process. However, current flanging technologies suffer from low efficiency and low automation, failing to meet production demands. Summary of the Invention

[0003] Based on the problems described in the background, the problem that this utility model aims to solve is:

[0004] Existing flanging technology is inefficient and has a low degree of automation.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An automatic flanging device for ultra-high molecular weight polyethylene (UHMWPE) pipes includes a flanging assembly, a pipe placement assembly, and a movable slide. The pipe placement assembly includes a positioning cylinder and a connecting plate. The bottom of the positioning cylinder is fixed to the movable slide via the connecting plate, and a support ring is provided at the top of the positioning cylinder. The flanging assembly includes a heating sleeve, a fixing frame, a lifting cylinder, a flanging mold, and a flanging cylinder. The heating sleeve is positioned above the positioning cylinder and is in the shape of a round cap, with its outer diameter being less than or equal to the outer diameter of the support ring. The heating sleeve is fixedly connected to the fixing frame, which is raised and lowered via the lifting cylinder. The flanging cylinder is fixed on the fixing frame. The flanging mold is located inside the heating sleeve, and a central opening is provided at the top of the heating sleeve. The push rod of the flanging cylinder passes through the opening and connects to the flanging mold.

[0007] Preferably, both ends of the movable carriage are equipped with pipe placement assemblies. The inner carriage of the movable carriage moves in both directions. When one end of the inner easel reaches the limit position, the positioning cylinder is aligned with the heating sleeve. When the positioning cylinder at one end is flipped, the worker can replace the pipe in the positioning cylinder at the other end, alternating back and forth to improve production efficiency.

[0008] Preferably, the flanging assembly and the pipe placement assembly are provided together, and one or more sets can be provided, wherein the fixing frame and the lifting cylinder can be shared, and multiple heating sleeves and flanging cylinders are fixed on the fixing frame.

[0009] Preferably, the positioning cylinder is connected to the connecting plate by bolts. This facilitates the replacement of positioning cylinders of different sizes and improves the applicability of this invention.

[0010] Preferably, the heating jacket is heated by a heating coupler arranged on the inner wall of the heating jacket.

[0011] Working principle: A UHMWPE pipe is placed inside the positioning cylinder, and a flange is fitted onto the pipe. The moving slide is adjusted to place the other end of the positioning cylinder into the pipe and fit a flange onto it. The fixing frame moves downwards, and the heating jacket presses against the support ring. The pipe end heats up and softens. The flanging cylinder pushes the flanging die downwards to squeeze the pipe, completing the flanging. After flanging, the push rod of the flanging cylinder retracts, the fixing frame rises, and detaches from the pipe. The moving slide moves the other end under the heating jacket. The flanged end is then replaced with a new pipe, ready for the next flanging cycle.

[0012] The beneficial effects of this utility model are:

[0013] This invention improves flanging efficiency, reduces manual intervention, and increases automation. Furthermore, its simple structure allows for flanging operations on different types of ultra-high molecular weight polyethylene pipes simply by changing the positioning cylinder, making it highly adaptable.
