[0030] The utility model provides Figure 1-6 The pit type tempering furnace shown in the figure comprises a furnace body 1, which is used to temper the workpiece in air.

[0031] The frame 3 is arranged outside the furnace body 1 and is used to drive the furnace door to merge with the furnace body 1;

[0032] The first gear cylinder 11 and the second gear cylinder 12 are respectively arranged inside the frame 3 and are used to drive the two sets of furnace covers to separate;

[0033] The heating ring 19 is arranged inside the furnace body 1 and is used to heat the workpiece inside the furnace body 1. A support frame 20 is fixedly installed inside the furnace body 1, a placement frame 21 is arranged above the support frame 20, and a partition plate 22 is fixedly installed on the lower side of the furnace body 1;

[0034] A preheating box 26 is arranged on one side of the furnace body 1 and is used to store the heat inside the furnace body 1. A conveying pipe 23 is arranged on one side of the furnace body 1. A high-temperature resistant pipe fan 24 is fixedly arranged at one end of the conveying pipe 23. A clamp 25 is arranged on the outside of the conveying pipe 23. The preheating box 26 is fixed on one side of the conveying pipe 23. A control valve 27 is arranged on one side of the preheating box 26. When the workpiece has just been processed, the temperature inside the furnace body 1 is adsorbed into the preheating box 26 for storage by the high-temperature resistant pipe fan 24. When the workpiece is tempered next time, the heat stored in the preheating box 26 is transferred to the furnace body 1 for preheating, so that the internal temperature of the furnace body 1 is increased before the workpiece works in the tempering furnace. After the temperature inside the furnace body 1 is increased, when the workpiece is placed in the furnace body 1, the temperature of the workpiece will directly increase, which can increase the efficiency of tempering.

[0035] like Figure 1 and Figure 2 As shown, a hydraulic cylinder 2 is fixedly installed on one side of the furnace body 1, a frame 3 is fixed above the hydraulic cylinder 2, a slider 4 is fixedly installed on one side of the frame 3, a fixed frame 5 is fixedly installed on one side of the furnace body 1, and a slide groove 6 is provided on the inner surface of the fixed frame 5. When the hydraulic cylinder 2 drives the frame 3 to rise and fall, the slider 4 behind the frame 3 is used to limit the rise and fall in the fixed frame 5 to enhance the stability during lifting.

[0036] like Figure 1 , Figure 2 and Figure 3As shown, a driving motor 7 is fixedly provided on one side of the frame 3, a first gear 8 is fixedly installed on one side of the driving motor 7, a second gear 9 is movably connected to one side of the first gear 8, a transmission rod 10 is fixedly installed inside the second gear 9, a first gear cylinder 11 is fixedly installed outside the transmission rod 10, and a second gear cylinder 12 is movably connected to one side of the first gear cylinder 11. Starting the driving motor 7 drives the first gear 8 and the second gear 9 to engage and transmit, which can drive the transmission rod 10 to rotate, and the furnace door is rotated to open.

[0037] like Figure 3 As shown, a first connecting rod 13 is fixedly installed on the upper end of the transmission rod 10, a first outer door 14 is fixedly installed below the first connecting rod 13, a second connecting rod 15 is fixedly installed above the second gear cylinder 12, and a second outer door 16 is fixedly installed below the second connecting rod 15. The first outer door 14 and the second outer door 16 are separated by rotating the first gear cylinder 11 and the second gear cylinder 12. Compared with the situation where the furnace door is set as a whole, the area occupied when opening is larger and it is inconvenient to open. Therefore, it is set into a double-opening type, which is convenient and quick to open the first outer door 14 and the second outer door 16.

[0038] like Figure 3 and Figure 4 As shown, a card slot 17 is provided on one side surface of the first outer door 14, and a card block 18 is fixedly installed on one side of the second outer door 16. The card slot 17 and the card block 18 cooperate between the first outer door 14 and the second outer door 16 to improve the compatibility of the two.

[0039] like Figure 1 and Figure 6 As shown, the clamp 25 is sleeved on the outside of the delivery pipe 23, and the delivery pipe 23 is fixedly connected to the preheating box 26. The preheating box 26 is provided with an insulation layer inside, and the material is good energy-saving nano-microporous insulation material. The preheating box 26 has a high temperature resistant setting inside, which can store heat for heat preservation, and is convenient for recycling to preheat the furnace body 1.

[0040] The working principle of the utility model is as follows: firstly, the external power supply is turned on, and then the placement rack 21 and the workpiece are placed into the furnace body 1 together, and then the drive motor 7 switch is turned on. When the current passes through the motor coil, a magnetic field is generated, so that the rotor of the motor generates magnetic force, thereby generating a rotational force. The first gear 8 and the second gear 9 are meshed and transmitted, so that the transmission rod 10 in the first gear 8 rotates together, and when the transmission rod 10 rotates, it drives the external first gear cylinder 11 and the adjacent second gear cylinder 12 to rotate relative to each other, aligning the card slot 17 on one side of the first outer door 14 at the upper end with the card block 18 on one side of the second outer door 16, and rotating and merging them. After merging, the drive motor 7 switch is turned off, and then the hydraulic cylinder 2 switch is turned on, and the frame 3 is lowered together with the first outer door 14 and the second outer door 16, and merged with the furnace body 1 and closed. After closing, the hydraulic cylinder 2 switch is turned off, and then the heating is turned on. Circle 19 switch is turned on to heat the inside of the furnace body 1 and temper the workpiece. When the tempering treatment is completed, the valve is opened first, and then the high-temperature resistant pipeline fan 24 switch is turned on to absorb the heat of the furnace body 1 into the preheating box 26 through the conveying pipe 23 for storage. After the adsorption is completed, the high-temperature resistant pipeline fan 24 switch is turned off, and the valve is closed. Finally, through the above steps, the first outer door 14 and the second outer door 16 are lifted and rotated to separate, and the workpiece and the placement rack 21 in the furnace body 1 are taken out. When the workpiece is tempered next time, the control valve 27 switch is turned on to transfer the heat stored in the preheating box 26 into the furnace body 1 for preheating, so that the internal temperature of the furnace body 1 is increased before the workpiece works in the furnace body 1. Finally, when the device is not in use, the external power supply is cut off, and the use process of the pit type tempering furnace is completed.

[0041] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
