Description

Technical Field

[0001] The utility model relates to the technical field of pipeline processing, in particular to a heating universal round pipe opening grinding device. Background Art

[0002] The HVAC system includes three aspects: heating, ventilation, and air conditioning. Round tubes are an important form of important parts that are indispensable for installing HVAC systems. Round tubes refer to steel materials with openings at both ends and a hollow concentric circle section, and a large ratio of length to circumference. During the production process, round tubes sometimes need to be cut. Since cutting will form burrs and cutting marks on the pipe mouth, in order to ensure the quality of the pipe, the pipe mouth needs to be polished. The efficiency of manual polishing of round tubes by workers is too low to meet customer needs. Therefore, the round tube mouth polishing device for HVAC came into being.

[0003] According to the announcement number: CN219684874U, it is a specific heating and general purpose round pipe mouth grinding device, including a base, a support box, a first motor and a grinding disc, the support box is fixedly connected to the top middle part of the base through a support foot, and a support rod is docked inside the support box, and a slide rail is sleeved on the outer wall of the support rod, an electric push rod is fixedly connected to the bottom end of the support rod, and connecting rods are connected on both sides of the support rod. Before grinding the pipe mouth, the utility model first docks one side of the HVAC pipe with the fixed seat, and then starts the first motor. At this time, the movable turntable squeezes the clamping piece through the clamping groove, which causes the distance between the clamping pieces to change, and then clamps one side of the HVAC pipe, thereby facilitating the heating and general purpose round pipe mouth grinding device to fix HVAC pipes of different sizes. This method helps to improve work efficiency, is convenient and fast, and saves time and effort.

[0004] Based on the search of the above patents and in combination with the equipment in the prior art, it was found that when the above equipment is used, although it can solve the problem that the existing grinding device cannot be adjusted according to the length of the pipe, resulting in poor clamping and fixing effect on HVAC pipes of different sizes and volumes, and there is an unstable middle support when grinding the HVAC pipes, resulting in time-consuming, labor-intensive, and inconvenient grinding of HVAC pipes of different sizes and lengths, resulting in low grinding efficiency.

[0005] However, in actual use, the above equipment can only fix and process a single pipe, which makes it impossible for the operator to grind multiple pipes at the same time, reducing work efficiency and having certain limitations. Therefore, we propose a new heating universal round pipe mouth grinding device. Utility Model Content
