Description

Technical Field

[0001] The utility model relates to the field of mechanical equipment, in particular to a pipe roller forming and cutting machine. Background Art

[0002] Common ways of connecting pipes in life, such as metal water pipes, are usually threaded or fitted. Fitted connections require pressing both ends of the pipe into convex and concave annular grooves for easy fitting. Existing roller grooving machines are mainly used for roller forming of metal sheets.

[0003] In the technical field, there are relatively few roll forming processes for fitting connections. According to the patent authorization public document CN213495846U, the manufacturing cost of equipment for fitting groove pressing is too high and the production efficiency is low. When working, one end of the pipe that has been cut to size needs to be connected to the positioning plate and the other end needs to be connected to the fixed frame, and then the rolling wheel on the positioning plate is used to roll out the matching groove, and then the other end is removed for processing. This method actually requires the use of multiple processes and multiple devices. Due to the use of multiple processes and multiple devices, the system error rate is easily increased, resulting in inaccurate pipe rolling cutting, eccentric pipe rolling cutting position and other problems, which ultimately leads to a high loss rate of pipe fittings, causing unnecessary waste for manufacturers.
