Abstract
Description
Technical Field
[0001] This utility model relates to the field of square tube processing, specifically an extrusion plastic device for square tube forming and processing. Background Technology
[0002] Square tubes are a type of rectangular tubing made from steel plates or strips through a specific process. They have a hollow cross-section and are widely used as pipelines for transporting fluids, such as oil, natural gas, coal gas, water, and certain solid materials. During the processing and production of square tubes, in order to improve the density and uniformity of the material and enhance the mechanical properties of the tubes, extrusion and shaping are usually required. During the extrusion process, the fiber flow lines of the metal material can be distributed along the length of the square tube, thereby enhancing its longitudinal strength and rigidity. Furthermore, extrusion shaping allows for precise control over the shape and dimensions of the square tube.
[0003] Chinese Patent No. CN222754089U discloses an extrusion molding device for square tube forming, including an extrusion chamber, in which a square tube is movably arranged. A motor is fixedly installed on the front outer wall of the extrusion chamber. There are two sets of extrusion molding mechanisms, both rotatably installed on the upper and lower sides of the square tube. An extension mechanism is fixedly arranged inside the extrusion molding mechanism. However, the extrusion molding device in the above patent is inconvenient to control the extrusion pressure on the square tube and lacks a buffer function, which can easily cause excessive extrusion of the square tube and affect the quality of square tube processing. Therefore, we propose an extrusion molding device for square tube forming to solve the above problems. Utility Model Content
