[0038] The adjusting device 9 includes a driving source 91, two guide rails 92 slidably arranged on the fixed partition 102, a positioning clamp 93 arranged on the guide rail 92, an advancing component 94 for controlling the positioning clamp 93 to advance, a driving component 95 for controlling the two positioning clamps 93 to make relative motion, and a lifting component 96 for controlling the positioning clamp 93 to rise;

Through the setting of the transmission member 97, the sheet metal part 5 is driven to move upward during the movement of the top mold 4, and the axis of the sheet metal part 5 is made to coincide with the axis of the mold ball 2, thereby achieving mechanical placement and precise positioning of the sheet metal part 5, solving the problem that the metal spinning machine is a large-scale industrial machinery, the blank is manually operated, which is prone to danger, and the manual placement is difficult to ensure the accuracy of the position of the sheet metal blank.
