Description

Technical Field

[0001] This utility model belongs to the field of spinning forming technology, and in particular relates to a precise temperature control device for hot spinning forming of titanium alloy heads. Background Technology

[0002] Spin forming is a metal plastic forming process used to manufacture axisymmetric hollow rotating parts. It is widely used in aerospace, automotive, chemical, and household goods industries, such as the production of titanium alloy heads. In the spin forming process, heating the workpiece is a critical step. To facilitate the heating of the workpiece, a precise temperature control device is usually used. Existing precision temperature control devices mainly consist of four parts: a magnetic induction coil, an infrared thermometer, a mounting bracket, and a controller. The magnetic induction coil is used for magnetic induction heating of the workpiece, the infrared thermometer is used to monitor the workpiece temperature in real time, the mounting bracket is used to install the magnetic induction coil and other structures, and the controller is used to control the magnetic induction coil. When the infrared thermometer detects that the workpiece has reached a predetermined temperature, the magnetic induction coil is shut off, thus achieving precise temperature control. However, during use, because the magnetic induction coil is fixed to the spinning machine by the mounting bracket, the distance between the magnetic induction coil and the workpiece affects the heating effect. Existing precision temperature control devices do not easily adjust the distance between the magnetic induction coil and the workpiece, making it difficult to control the heating effect. Furthermore, the heating efficiency of the magnetic induction coil is also related to the number of coil turns. During use, it is not convenient to quickly replace different magnetic induction coils to heat the workpiece, and it is also difficult to control the heating efficiency.

[0003] To address these issues, we provide a precise temperature control device for hot spinning of titanium alloy heads. Utility Model Content
