Description

Technical Field

[0001] The invention relates to the technical field of metal cutting, in particular to a high-precision numerical control cutting device for sanitary ware metal pipes. Background Art

[0002] Pipes are materials used to make pipe fittings. Different pipe fittings require different pipes. The quality of pipes directly determines the quality of pipe fittings. Therefore, pipes are indispensable materials in many fields such as construction projects, power plants, chemical plants, etc. With the development of science and technology, the pipes used in home decoration have also undergone many updates and upgrades, from the initial ordinary cast iron pipes and cement pipes, to the later reinforced concrete pipes and asbestos cement pipes, and then to today's ductile iron pipes, galvanized steel pipes, plastic pipes and aluminum-plastic composite pipes. The types and performance of pipes are constantly improving.

[0003] In the field of sanitary ware, metal pipes are widely used in the production of sanitary ware such as faucets, showers, and toilets due to their excellent physical and chemical properties, such as corrosion resistance, high temperature resistance, and high strength. These metal pipes usually need to undergo precise cutting, bending, welding and other processing techniques to be made into sanitary ware fittings that meet the requirements.

[0004] In the traditional pipe cutting technology, manual or semi-automatic cutting methods are mainly used, such as using grinding wheel cutters, sawing machines and other tools for cutting. The existing cutting method can only perform one cutting in one cutting cycle, which is inefficient. Summary of the invention

[0005] In view of the above technical problems, the present invention discloses a high-precision CNC cutting device for sanitary ware metal pipes, which can effectively solve the problems in the background technology. When the present invention is in use, the alternating feeding mechanism can swing and load between the loading and unloading mechanisms on both sides, take the metal pipe at one end, cut the metal pipe by swinging through the saw blade, and then remove the cut metal pipe at the other end. While removing, a new metal pipe is taken up again, and swing back again to complete the secondary cutting. In this way, two cuts will be completed in one swinging cycle, and the gap of one cutting cycle is fully utilized to increase cutting, so that the cutting efficiency is doubled; both ends of the limit frame are provided with notches for discharging materials, and the notches become narrower as they go inward, so as to adapt to metal pipes of different diameters. The smaller the diameter of the metal pipe, the closer it can be placed to the inside, and then the metal pipe is clamped and fixed by a buckle, which is very simple and practical; when the metal pipe falls from the loading rack into the groove on the limit rack, the limit rod can push the metal pipe inward, so that the cutting position is opposite to the saw blade, so as to achieve precise cutting.

[0037] Working principle: When the present invention is used, firstly, materials are prepared on the loading racks 21 on both sides, and the automatic loading and unloading and cutting work of the device are performed through numerical control. Firstly, the servo motor I16 is started to drive the transmission shaft 17 to rotate, and the rotating wheel 13 is driven to rotate through the belt I15. The eccentric shaft on the rotating wheel 13 drives the swing rod 4 to swing, and the swing stops at the loading rack 21 at one end. The servo motor III25 is started to drive the dial wheel 24 to rotate a certain angle, so that the metal pipe limited by the dial wheel 24 is moved and dropped, so that the metal pipe falls into the groove on the limiting rack 1; Then, the cylinder II 9 is started, driving the limit rod 10 to retract inward, thereby driving the metal tube to slide inward, so that the point to be cut is just moved to the saw blade 11, and then the cylinder I 7 is started, driving the slide block 6 to slide upward, thereby driving the buckle 3 to rotate through the connecting rod 5, so that the buckle 3 holds the metal tube tightly; Then the swing rod 4 continues to swing in the opposite direction, swings to the saw blade 11 to cut the metal pipe, and pauses when swinging to the other end. The buckle 3 is driven to unfold, so that the cut metal pipe slides onto the unloading rack 23. A partition is provided in the middle of the unloading rack 23, so that the two different ends of the cut can fall to different positions respectively. The next step is to continue loading from this end, and repeat the above steps for repeated cutting.
