Through adopting above-mentioned technical scheme, when carrying out the tempering work, heat the inside of tempering furnace through heating element, make its inside air circulate through thermal cycle mechanism, when its inside temperature increase, the air enters into the ventilation pipe and finally enters into in the air-supply line, through the inside of air intake reentrant tempering furnace, because the air-supply line is vertical setting, can make entering into the tempering furnace that the air can be even for the work piece is heated evenly.
The utility model discloses further set up to: the bottom of stove outer covering rotates and is connected with first axis of rotation, the top fixedly connected with second axis of rotation of first axis of rotation, the top fixedly connected with third axis of rotation of second axis of rotation, the second axis of rotation with the third axis of rotation is overlapped respectively and is equipped with first board and the second of placing and places the board, first board and the second of placing is placed the board and is located respectively the top of first axis of rotation and second axis of rotation, the bottom of stove outer covering is installed and is used for the drive the servo motor of first axis of rotation.
Through adopting above-mentioned technical scheme, place the board through setting up two first boards of placing and the second, can place the work piece of difference in different height position to further promote the degree of consistency to the work piece heating, surely be convenient for place the board and place the board with the second and take out first board of placing through servo drive and rotate, place the board with the second and rotate in order to drive first board of placing and the second and place the board and rotate, make the work piece place the board with the second along with first board of placing and rotate together, in order to guarantee the degree of consistency of work piece in the course of the work.
The utility model discloses further set up to: the ventilation pipe is connected with an air supply pipe, and the air supply pipe is connected with an air heater and a valve.
Through adopting above-mentioned technical scheme, before carrying out tempering work, through starting the air heater and opening the valve, let in hot-air to the tempering furnace in to preheat the tempering furnace, further promote its working effect.
Drawings
Fig. 1 is a schematic cross-sectional view of an embodiment of the present invention.
Detailed Description
The embodiment of the present invention will be further explained with reference to fig. 1.
The utility model provides an efficient pit-type tempering furnace, including stove outer covering 1 and the stove inner bag 2 of setting with stove outer covering 1 inner wall, heating element 3 is installed to stove inner bag 2 inner walls, the top of stove outer covering 1 is provided with thermal cycle mechanism, thermal cycle mechanism is including installing in fan 4 of stove outer covering 1 top inner wall and the motor 5 that is used for driving the fan, the air-supply line 6 of vertical setting is installed to stove inner bag 2 inner walls, the lateral wall that stove outer covering 1 was stretched out on the top of air-supply line 6 is connected with ventilation pipe 7, ventilation pipe 7's end connection is in the bottom of stove outer covering 1 and communicates in the inside of stove outer covering 1 son, a plurality of air intakes 8 have been seted up along.
