Problems solved by technology

[0002] At present, after the heat treatment of the metal plate, due to the high heat treatment temperature, it usually reaches above the eutectic line, and the internal grains re-grow, and then the rapid low temperature after taking it out makes the grains finer and improves the mechanical properties of the metal plate. During the thermal process, there is internal stress on the surface of the metal plate, which will cause bubbling on the surface if it is serious, and it needs to be released by external force. The existing ones are manually beaten or squeezed by a pressure roller to form surface pressure on the metal plate. However, because the surface of the pressure roller is straight, the pressure value is fixed during extrusion, so the release effect on the internal stress is limited, and it is impossible to adjust and correct the position where the internal stress of the plate is large. The effect is general, the operation process is complicated, and the pressing The extrusion of the roller can only be aimed at the entire width, and cannot be strengthened only for the local area. Existing mechanical strengthening equipment such as shot blasting machines and sand blasting machines, which shoot steel shots to the metal surface through high pressure, have a limited working range. The equipment is bulky, and it is mostly used to strengthen the surface of a single part. The span of the metal plate is large, and the effect of only shot blasting is poor.

[0003] Publication number CN202192550U discloses a multi-station turntable reinforced shot blasting machine, which is characterized in that a main rotary table is installed in the shot blasting cleaning room, a shot blasting device is installed outside the shot blasting cleaning room, and steel shots are fixed above the shot blasting cleaning room. The sorter, the screw conveying device is fixed under the shot blasting cleaning room, and the bucket elevator is fixed behind the shot blasting cleaning room. The inlet and outlet of the bucket elevator are separated from the screw conveying device and the steel shot The discharge port of the steel shot separator is connected to the shot blasting machine; the main rotary table is fixed with a partition wall assembly that divides its table into five stations, and the five stations are two shot blasting workers. One station, two isolation stations and one loading and unloading station, each station is rotatably installed with a planetary table, this device is mainly aimed at the surface strengthening of a single component, not suitable for the strengthening of metal plates, especially after heat treatment Mechanical strengthening of sheet metal with high surface stress
