Description

Technical Field

[0001] The utility model relates to a slitting device, in particular to a slitting device for metal pipe production, belonging to the technical field of metal pipe production. Background Art

[0002] Pipes are materials used to make pipe fittings. Different pipe fittings require different pipes. The quality of the pipes directly determines the quality of the pipe fittings. Construction projects, power plants, chemical plants, etc. use this type of pipes, including PPR pipes, PVC pipes, UPVC pipes, metal pipes, fiber pipes, composite pipes, galvanized pipes, hoses, reducers and water pipes. During the production and processing of metal pipes, the metal pipes need to be cut into different lengths according to demand through a metal pipe production slitting device.

[0003] Among them, a pipe slitting device with application number "CN202120403509.6" includes a workbench and a slitting seat. A straightening machine for straightening the pipe is provided at one end of the workbench. The slitting seat is connected to the top surface of the workbench and close to the straightening machine. The straightening machine is provided with a transmission component for transmitting the pipe to the slitting seat. A baffle is provided in the slitting seat. The baffle is provided with a first through hole for the pipe to pass through. The pipe transmitted from the transmission component to the slitting seat is arranged to pass through the first through hole. A slitting plate is slidably connected in the slitting seat. The sliding direction of the slitting plate is horizontal and perpendicular to the transmission direction of the pipe. A driving component for driving the slitting plate to move is provided on the top surface of the workbench. The driving component is connected to the slitting plate. A second through hole for the pipe to pass through is provided in the middle of the slitting plate. A blade is provided in the second through hole. The blade for reciprocatingly cutting the pipe is vertically arranged. The present application has the effect of improving the slitting efficiency. After further searching, it was found that the steel wire skeleton composite pipe slitting device with application number "CN202220819316.3" includes a slitting machine and a base plate. The base plate is arranged on one side of the pipe outlet of the slitting machine, and the top surface of the base plate is connected with a flippable support mechanism, and the top surface of the base plate is provided with a conveying assembly; the support mechanism includes a first support plate, a second support plate, a pillar and a driving assembly. When the utility model cuts the composite pipe inside the slitting machine, the support mechanism is first used to support the composite pipe to be cut, thereby ensuring the stability during slitting. After the composite pipe is slid and guided out from the pipe outlet of the slitting machine, the second support plate is flipped and connected to the conveying assembly through the driving assembly, so that the composite pipe rolls onto the conveying assembly, thereby improving the convenience of transporting the composite pipe after slitting.

[0004] However, the above two types of slitting devices still have certain shortcomings when in use. During the slitting process of the pipe, a large amount of debris and dust will be generated at the incision, which is difficult to clean and not convenient for better collection and cleaning of the debris and dust generated during the processing.
