Abstract

The invention relates to the technical field of metal casting, in particular to casting equipment and a casting method of a metal wear-resistant pipe. Through setting up clearance subassembly and dust filter net, can clear up casting mould section of thick bamboo inner wall after the drawing of patterns, the dust filter net then is used for catching and collecting the dust that produces in the clearance process. In the initial demoulding stage of the next metal wear-resistant pipe, the second driving unit carries out short-time reverse suction on the dust removing cavity, so that air flow reversely passes through the dust filtering net, and the dust is automatically removed by utilizing the generated recoil and vibration action, so that the attached dust is separated from the dust filtering net, and the continuous smoothness and the dust removing efficiency of the dust filtering net are maintained.

Background The metal wear-resistant pipe is used as a key component in an industrial conveying system, is widely applied to material conveying pipelines in industries such as mines, metallurgy, electric power, building materials and the like, and the performance of the metal wear-resistant pipe directly influences the service life of the pipeline and the operation efficiency of the system. With the continuous improvement of the requirements of industrial equipment on the wear resistance, the centrifugal casting technology gradually becomes a main stream process for manufacturing the high-performance metal wear-resistant pipe, and the metal liquid is uniformly attached to the inner wall of a pipe die through high-speed rotation to form a compact and uniform wear-resistant layer, so that the centrifugal casting technology becomes the main stream manufacturing process of the high-performance metal wear-resistant pipe. Meanwhile, modern industrial equipment is rapidly evolving towards high strength and high toughness and light weight, which is not only reflected in end products, but also deeply influences the manufacturing requirements of key parts of the end products. For example, in equipment such as advanced mining machinery and engineering vehicles, advanced materials such as die-cast aluminum alloy for high-strength lightweight structural members are increasingly used for structural frames and accessory mounts for improving energy efficiency and maneuverability. Therefore, the adoption of high-strength and high-toughness lightweight aluminum alloy (particularly high-performance aluminum alloy suitable for die casting and precision casting) for preparing structural parts through centrifugal casting has become an important technical path for realizing weight reduction and specific strength improvement of the components. However, during the centrifugal casting process, after each casting cycle is completed, the residual height Wen Huichen of the inner wall of the cylinder must be thoroughly removed during cleaning to ensure the quality of the inner wall of the next casting.
