Abstract
The invention relates to a medium-frequency heating and transverse feeding and discharging mechanism for a round metal rod, in particular to a method for medium-frequency heating and transverse automatic feeding and discharging of a round metal rod. In the method, after a feeding mechanism receives a rod, the rod goes onto a guide rail under the action of self-gravity and is charged into a heating furnace by driving a pushing block with a pushing oil cylinder; the heated hot rods move towards a high-end outlet step by step and one by one under the push of the following rod; when a foremost rod is pushed onto a downward sloping guide rail face, the hot rod rolls and slides along the guide rail into a discharge channel under the action of self-gravity of the rod so as to wait for execution of the next step; and all the steps are automatically repeated in this manner. The mechanism is an integrated mechanical, electric and hydraulic medium-frequency heating and transverse feeding and discharging mechanism for a round metal rod. Due to transverse discharging, the discharging time is shortened, therefore, the discharging temperature of the heated rods is uniform, which plays a very important role in the braiding quality of the next step and guaranteeing the consistency and stability of the braided products. The mechanism has the advantages of high production efficiency, steady production process and safe reliability.
