C, bar medium frequency induction heating furnace composition and use method :

1, the feed rod-frequency induction heating furnace method: after the sawing machine feed, by the traffic to the next good material feeder, the discharge into the buffer means, when receiving a signal lack of material feeding device, feed on the feeder Enter a blank. The billet is then pushed into the heating furnace by the cylinder pushing device for heating. After the heated billet is discharged from the furnace mouth, the signal is outputted by detecting the photoelectric switch, and the fast discharge machine and the infrared temperature measuring system work simultaneously. The blank is lifted by a quick discharge machine and sent to a two-position sorting machine for sorting. Under-temperature and over-temperature materials enter the unqualified bin. The qualified material is turned over to the feeding feeder via the turning mechanism, and the material is fed into the press in cooperation with the user's own robot.

The first roller of the quick discharge machine is designed as a hexagonal roller. When the heat-adhesive material appears, the six-sided roller can realize the vertical movement of the discharge and open the bonding portion. This can effectively solve the problem of sticking.

When the blank on the discharge device is too small and the position of the proximity switch is not detected, an audible and visual signal will be provided to inform the loading.

When the photoelectric switch of the feeder detects the shortage of material for 30 seconds, if there is still no follow-up incoming material, the control system automatically reduces the power of the intermediate frequency power supply to enter the insulation power to prevent the furnace material from being melted. When the subsequent material comes again, the system returns to normal operation.

The complete set of equipment is automatically controlled by the PLC and has a manual automatic transfer switch.
