Heating furnace with quickly-replaced blade wheel shaft

Abstract

The invention discloses a heating furnace with a quickly-replaced blade wheel shaft. The heating furnace comprises a furnace body, a furnace cover and a blade wheel shaft structure, wherein the blade wheel shaft structure comprises a main shaft, at least one spoke and multiple blades, the main shaft is horizontally arranged; the spoke and the main shaft are connected through a spline pair; the blades are uniformly distributed along the circumferential direction of the spoke and are inserted into the spoke in a perpendicular manner; two ends of the main shaft extend out of the furnace body; one end of the main shaft is connected with a servo motor and the other end of the main shaft is connected with a sliding bearing bracket. By virtue of the heating furnace with the quickly-replaced blade wheel shaft, flat blanks and finished parts can be continuously and regularly conveyed; when the differences of the parts are great, the blade wheel shaft can be quickly replaced; the manufacturing cost is low, the size is small and the energy consumption is low; when the heating furnace is used in an automatic production line for thermal formation of high-strength steel plate punching pieces, the problems that an existing device is large in size, high in cost, small in application range and the like are solved.

Description

technical field [0001] The invention relates to a heating furnace for thermoforming, in particular to a quick-change blade wheel shaft type heating furnace, which belongs to the field of thermoforming, and is specifically used in an automatic production line for thermoforming of high-strength steel stamping parts. Background technique [0002] Automobile hot-formed high-strength steel parts have been widely used, and it is the best way to reduce the weight of automobiles today. Many countries in the world have been able to produce this automatic line, but our country is not self-made so far. At present, more than 20 domestic automatic lines are all imported. According to the current annual output of more than 10 million cars, at least more than 100 such production lines are needed. (Each set of automatic line including high-speed press is about 70 million RMB). Most of the automatic lines produced abroad are heated by tunnel furnaces, and there are also drawer-type furnac...
