Optionally, the automatic feeding device further includes a first position sensor and a second position sensor, as shown in fig. 6, the first position sensor 35 is disposed at an upper limit position of the inlet range of the intermediate frequency induction heating furnace, and the second position sensor 36 is disposed at a lower limit position of the inlet range of the intermediate frequency induction heating furnace, and when the end position of the round steel blank is between the upper limit position and the lower limit position, the round steel blank can be pushed into the intermediate frequency induction heating furnace.
As shown in fig. 7, the automatic feeding device further includes a controller 37, and the controller 37 is configured to control the operation of the tumble cylinder 2 and the assist cylinder 21 according to the position signals output from the first position sensor 35 and the second position sensor 36.

In this alternative embodiment, the auxiliary cylinder 21 is not rated to support the support shaft 32 and the round steel billet for the turning action. When upset cylinder 2 resets the action, assist cylinder 21 carries out the propelling movement action, because assist cylinder 21's rated power is less than upset cylinder 2's rated power and is not enough to support back shaft 32 and carry out the action of overturning, consequently, back shaft 32 wholly resets the action, because assist cylinder 21's propelling movement produces the holding power, can prevent because inertia effect leads to back shaft 32 and round steel blank's the range of resetting too big, and lead to the round steel blank to surpass lower limit position, can guarantee that the action of resetting of back shaft is more accurate, stable.

The controller 37 converts the working step values corresponding to the turnover cylinder 2 and the auxiliary cylinder 21 according to the first preset step value and the second preset step value, and controls the two cylinders to act.
Optionally, when the second position sensor 36 detects that the round steel blank exceeds the lower limit position of the inlet range of the intermediate frequency induction heating furnace, a second position signal is output to the controller 37, the controller 37 controls the turnover cylinder 2 to perform pushing action according to a third preset step value, and controls the auxiliary cylinder 21 to perform pushing action according to a fourth preset step value, until the second position sensor 36 stops outputting the second position signal, that is, the round steel blank is in the inlet range of the intermediate frequency induction heating furnace, and the round steel blank is in a straight line with a push rod of the pushing mechanism and the inlet of the intermediate frequency induction heating furnace.
Optionally, the third preset step value is smaller than the fourth preset step value.
The third preset stepping value and the fourth preset stepping value correspond to stepping of the running track of the round steel blank, namely the overturning cylinder 2 pushes the round steel blank according to the third preset stepping value, the radian distance of the third preset stepping value of the round steel blank is predicted to overturn, the auxiliary cylinder 21 pushes the round steel blank according to the fourth preset stepping value, and the radian distance of the fourth preset stepping value of the round steel blank is predicted to overturn. The controller 37 converts the working step values corresponding to the turnover cylinder 2 and the auxiliary cylinder 21 respectively according to the third preset step value and the fourth preset step value, and controls the two cylinders to act.
In this alternative embodiment, the precision of the motion of the turnover cylinder 2 is lower than that of the motion of the auxiliary cylinder 21, and therefore, the third preset step value for controlling the motion of the turnover cylinder 2 is smaller than the fourth preset step value for controlling the motion of the auxiliary cylinder 21. Adopt this optional embodiment, because the rated power of auxiliary cylinder is less than the rated power of upset cylinder and is not enough to drive back shaft 32 and carry out the action of overturning, consequently, auxiliary cylinder 21 only plays the auxiliary action to the action of upset cylinder 2 for after upset cylinder 2 drives back shaft 32 upset third preset step value and reaches preset position, can not produce because of the action of gravity of back shaft and round steel blank and reset, the round steel blank reliably stops in preset position.
The first position sensor 35, the second position sensor 36 and the auxiliary cylinder 21 are only used for fine adjustment of the position of the round steel blank, so that the first preset step value, the second preset step value, the third preset step value and the fourth preset step value are far smaller than the arc length distance of the round steel blank moving in the overturning process. For example, the first preset step value, the second preset step value, the third preset step value and the fourth preset step value are 1-5 cm, such as 1cm, 2cm, 3cm, 4cm and 5 cm.
The present invention does not relate to the improvement of the existing control program, and the control process is realized by adopting the existing known program.
The heating system for forging of the utility model has simple integral structure and low cost; the turnover mechanism can reliably move hundreds of kilograms of round steel blanks and even hundreds of kilograms of round steel blanks, and the moving position is accurate; the system has the advantages of good durability of main parts, high reliability and long service life.
