Problems solved by technology

During the flame heating process, the scale of the blank will fall into the horizontal guide groove of the furnace. After the furnace body has been used for a long time, it is difficult to push the material due to the accumulation of oxide scale, and even the guide groove is blocked.

Abstract

The invention discloses a heating furnace for forging. The heating furnace comprises a furnace body, guide grooves and heating burners, the guide grooves comprise an upper guide groove, a lower guide groove and a material receiving guide groove, the upper guide groove is of a U-shaped structure comprising a first bottom plate and two vertical plates, a plurality of first through holes are formed in the first bottom plate, the lower guide groove comprises a second bottom plate, a plurality of turnover plates are hinged to the second bottom plate, the overturning plates penetrate through the first through holes from the bottoms of the first through holes in a one-to-one correspondence mode, all the overturning plates obliquely abut against the edges of the first through holes in a scale shape, the second bottom plate is slidably connected with the first bottom plate through a sliding seat, second through holes are formed between the hinged positions of every two adjacent overturning plates and the second bottom plate, the material receiving guide groove is formed below the second bottom plate. According to the heating furnace for forging, oxide skin in the guide grooves can be cleaned in time, and the influence on the production process is avoided.

Description

technical field [0001] The invention relates to the technical field of forging heating furnaces, in particular to a heating furnace for forging. Background technique [0002] According to the deformation temperature, forging can be divided into hot forging, warm forging and cold forging. Hot forging and warm forging require heating, but cold forging does not require heating. Heating can recombine and recrystallize the metal lattice, improve metal plasticity, reduce deformation resistance, facilitate metal deformation, and obtain good post-forging microstructure and mechanical properties. Heating has a great contribution to improving forging productivity, ensuring the quality of forgings and saving energy consumption. Direct forging without heating requires larger tonnage equipment, and it is easy to cause lattice distortion of the material, generate internal stress, and easily cause cracks or ruptures in forgings. Common heating methods in the prior art are divided into fl...
