Description

Technical Field

[0001] The utility model belongs to the field of pipe production and processing equipment, and specifically relates to a cutting device for pipe production. Background Art

[0002] In the process of plastic pipe production and processing, a cutting device is needed to cut it to obtain the required specifications and sizes. For example, CN216229600U discloses a cutting device for PPR pipe production, which can drive the L-shaped plate to move up and down by extending or shortening the first electric push rod, thereby driving the second servo motor to move up and down, and then driving the cutting knife to move up and down, so as to achieve the purpose of driving the cutting knife to cut the pipe to be cut.

[0003] However, the existing cutting device generally needs to cut from top to bottom when cutting the pipe. The cutting knife needs to completely pass through the cross section of the pipe when cutting the pipe. If the pipe with a thicker diameter is cut, a larger cutting knife is required to complete the pipe cutting work. Generally, the larger the cutting knife, the higher the price. Equipping cutting knives of various specifications will increase the production cost invisibly. In addition, for cutting pipes of different diameters, it is troublesome to disassemble and replace the cutting knife, which wastes manpower and is inefficient. For this reason, we propose a production cutting device suitable for pipes of different diameters. Utility Model Content
