Energy-saving tempering furnace

Abstract

The invention discloses an energy-saving tempering furnace. The energy-saving tempering furnace comprises a furnace body; a turntable is arranged on the inner wall of the bottom of the furnace body; avertical support shaft is arranged in the center of the turntable; a rotating ring is arranged at the top of the support shaft; vertical baffle plates are arranged on the inner wall of the bottom ofthe furnace body; the baffle plates are positioned on the left side and the right side of the turntable; a horizontal fence plate is arranged between the baffle plates; the rotating ring is mounted atthe bottom of the fence plate through a bearing; the bottom of the rotating ring is connected with four sets of identical mounting bases through screws; the bottom of a mounting base is hinged with abracket; parts to be machined are placed in the bracket; furnace doors are prearranged on the front side and the back side of the furnace body, and are provided with through port grooves; and flashboards are mounted in the through port grooves through hinges. The energy-saving tempering furnace can guarantee uniform heating of the machined parts inside, can recycle heat to achieve the energy saving effect, and meanwhile, is convenient for staff to take out the parts to guarantee the production efficiency.

Description

technical field [0001] The invention relates to the technical field of tempering furnaces, in particular to an energy-saving tempering furnace. Background technique [0002] The tempering furnace is used for tempering general metal parts in air and quenching, annealing and aging heat treatment for aluminum alloy die-casting parts, pistons, aluminum plates and other light alloy parts. In the process of automobile manufacturing, many spare parts need to be quenched, annealed, and aging heat treated in a tempering furnace. However, most of the existing tempering furnaces consume a lot of energy and have low heat utilization rates. [0003] The patent document whose notification number is CN206418160U discloses a kind of energy-saving tempering furnace, which includes a furnace body. A furnace cavity is arranged inside the furnace body. A furnace door is installed at the front end of the furnace body. The plate is fixed on the inner wall of the rear end of the furnace body, an...

However, most of the existing tempering furnaces consume a lot of energy and have low heat utilization rates.

[0003] The patent document whose notification number is CN206418160U discloses a kind of energy-saving tempering furnace, which includes a furnace body. A furnace cavity is arranged inside the furnace body. A furnace door is installed at the front end of the furnace body. The plate is fixed on the inner wall of the rear end of the furnace body, and an air duct is left between the baffle plate and the side wall of the furnace body. A shelf is arranged between the two baffle plates, and a fence plate is arranged above the shelf. Above the fence plate Fan blades are provided, and the first motor is installed on the top of the furnace body. This tempering furnace improves the heat utilization rate and makes the workpiece heated more evenly. However, since the storage rack is located inside the furnace cavity, the installation of the workpiece before being heated And it is very troublesome to take out after tempering, so we need to improve it
