Description

Technical Field

[0001] This utility model relates to the field of bar stock venting, specifically to a bar stock venting mechanism for induction heating. Background Technology

[0002] Currently, the movement of the bar stock after heating in the sensor is achieved by having the next bar stock push against the previous one in turn. However, for the heating and transfer of the last few bars stock, since there are no subsequent bars to push against, an additional venting rod must be used to achieve the pushing action.

[0003] However, the length of the sensors varies, especially when dealing with longer sensors, the venting rod also needs to be lengthened accordingly. Since the travel of the venting rod is related to the length of the sensor, at least twice the length of the sensor must be reserved at one end of the sensor. At the same time, a corresponding drive device is required to drive the venting rod forward a distance equal to the length of the sensor. This poses additional challenges to the drive structure and travel of the drive device.

[0004] Currently, the solution to the problem of emptying long sensor bars is often to use multiple emptying rods spliced ​​together. However, splicing during the emptying process not only requires proximity to the sensor, which is a harsh and dangerous environment, but also requires special customization of the splicing structure and materials at the splicing points due to the influence of the temperature inside the sensor, causing great trouble for enterprises.
