Technical Field

[0001] The utility model relates to the field of sizing machines, in particular to a safety connection device for a sizing machine. Background Technique

[0002] A sizing machine is a device used in the process of steel pipe production. Its main function is to perform sizing rolling on the steel pipe rolled by a Pilger rolling mill to obtain a steel pipe with a higher-precision external dimension. The sizing machine reheats the steel pipe through a walking beam furnace and then performs sizing rolling to make the steel pipe reach the required dimensional accuracy and roundness, further improving the external surface quality of the steel pipe.

[0003] At present, for the safety of staff, a safety protection plate is usually installed on the sizing machine. However, when the safety protection plate is connected to the base, multiple bolts are generally used for connection and installation. The bolt connection speed is slow, and external tools are required for connection during installation, which greatly reduces the installation progress of the staff. For this reason, we propose a safety connection device for a sizing machine to solve the above problems. Content of the Utility Model
