Description

Technical Field

[0001] The utility model relates to the field of stabilizer bar production equipment, and more specifically, to a stabilizer bar feeding mechanism of a thermoforming machine. Background Art

[0002] Cars are very common in people's lives, and cars have greatly facilitated people's lives and travel. Stabilizer bars are important components in automobile suspension systems. Stabilizer bars are used to increase the suspension roll angle stiffness and reduce the body inclination angle, thereby facilitating stable driving of the vehicle. In the production process of stabilizer bars, a hot forming machine is required to be used to make rod-shaped steel into stabilizer bars. Therefore, a feeding mechanism is required to place the rod-shaped steel inside the stabilizer bar. The existing feeding mechanism lacks a supporting structure. When producing stabilizer bars with longer lengths, rod-shaped steel with longer lengths is required. During the steel lifting process, due to the excessive length of the rod, the rod is easily shaken during the rising movement, which is inconvenient to feed. At the same time, the existing feeding structure can only grab the rod first and then feed it. After feeding, the finished stabilizer bar needs to be removed from the hot forming machine, and then a new rod is grabbed, so the feeding time is long and the feeding efficiency is low, which increases the production time of the stabilizer bar.
