Description

Technical Field

[0001] The utility model relates to the field of pipe cutting mechanisms, in particular to a pipe cutting mechanism for urea pipe production. Background Art

[0002] Automobile urea pipes usually refer to urea solution delivery pipes, which are used to deliver vehicle-mounted urea solution to the vehicle's SCR (selective catalytic reduction) system to help reduce diesel vehicle exhaust emissions and meet emission standards. Urea pipes are divided into metal and flexible urea pipes. Since flexible urea pipes are usually longer when they are produced, in order to meet the required use requirements, a pipe cutting device is required to cut them into the required length.

[0003] When the existing pipe cutting device is in use, some urea pipes need to be moved to the corresponding position and then stopped. The pipe cutting device cuts at the required position to cut out the urea pipe of the required length. The above steps are repeated reciprocally to cut out the urea pipe of the required length. However, cutting after stopping at the reciprocating position is not conducive to improving the pipe cutting efficiency.

[0004] In order to solve the above problems, the present application proposes a pipe cutting mechanism for urea pipe production. Utility Model Content
