Description

Technical Field

[0001] The utility model relates to the technical field of forging, in particular to a medium-frequency forging electric heating furnace with cylinder assisting force. Background Art

[0002] The medium frequency electric heating furnace is used to heat the blanks, and the blanks are placed under the forging machine for forging after they are red hot. For example, the patent with the national authorized patent announcement number CN213444664U discloses a feeding device for the medium frequency electric heating furnace, which includes two power-assisting mechanisms and a conveyor belt, and the two power-assisting mechanisms are respectively arranged on the opposite sides of the conveyor belt; the blanks are conveyed to the furnace mouth of the medium frequency furnace through the conveyor belt, and rollers are used to assist in feeding. Compared with the cylinder feeding of the prior art, the rollers of the power-assisting mechanism rotate at a uniform speed, and the force applied to the blanks is uniform, so that the feeding speed is more stable and the blanks are heated uniformly; the lower part of the power-assisting mechanism is a retractable structure, which can be adjusted according to the size of the blanks; baffles are arranged on both sides of the conveyor belt, which can effectively prevent the blanks from deviating from the conveyor belt; a support frame is arranged under the conveyor belt, and a box is arranged outside the conveyor belt and the support frame, which can effectively prevent external debris from interfering with the conveying device, and also play a protective role, improving the safety of the equipment.

[0003] However, the feeding device of the above-mentioned medium frequency electric heating furnace can only transport the blanks into the furnace, but cannot quickly take all the heated blanks out of the furnace after heating them. This will cause the blanks to stay in the furnace for too long, resulting in uneven temperature distribution and affecting the forging quality. In addition, long-term contact with the outside air in a high temperature environment will cause oxidation of the workpiece surface and form oxide scale, affecting subsequent processing and product appearance.
