[0021] Next, the technical solutions of the present utility model will be clearly and completely described in conjunction with the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.
[0022] Refer to Figures 1 to 5 , the present utility model provides a technical solution: a quenching furnace with a discharging function, including a furnace body 1, a sealing door 2 is connected to the feeding port of the furnace body 1 in a lifting manner, a third motor 18 is fastened on the top of the furnace body 1, and a fixed seat 16 is fastened at the upper end of one side of the sealing door 2. A second screw 17 is connected to the fixed seat 16 in a threaded manner. The bottom of the second screw 17 is rotatably connected to the top of the furnace body 1. The top of the second screw 17 is rotatably connected to a support 24 connected to the top of the furnace body 1. The lower end of the second screw 17 is coaxially connected to a driven wheel 20. The output end of the third motor 18 is coaxially connected to a driving wheel 19. The driving wheel 19 is meshed with the driven wheel 20. Guiding seats 3 are symmetrically connected to the feeding port of the furnace body 1. The sealing door 2 is slidably connected in the guiding seats 3. As Figure 1 , 2 shown, when the third motor 18 rotates, the fixed seat 16 and the second screw 17 are lifted and slid, and under the drive of the moving fixed seat 16, the up and down movement of the sealing door 2 can be realized, and thus the feeding port of the furnace body 1 can be sealed.
[0023] As Figure 1 , 3 shown, a placing rack 11 for placing workpieces is slidably arranged inside the furnace body 1, and a plurality of strip-shaped limiting seats 12 are fastened inside the furnace body 1. A plurality of limiting gaps 22 matching the strip-shaped limiting seats 12 are opened at the bottom of the placing rack 11. When the placing rack 11 slides inside the furnace body 1, the clamping cooperation between the strip-shaped limiting seats 12 and the limiting gaps 22 can ensure the stable pushing and pulling of the placing rack 11, and thus the stable transportation of the workpieces can be realized. At the same time, in order to facilitate the rapid removal and discharging of the placing rack 11 from the furnace body 1, connecting rings 10 are symmetrically arranged at both ends of the placing rack 11.
[0024] As shown Figure 1 , 3 In the figure, strip-shaped supports 7 with a hollow interior are symmetrically arranged on both sides of the furnace body 1. The top of the strip-shaped support 7 is slidably connected to the mounting box 4. An opening 9 is formed at the top of the strip-shaped support 7. A first screw rod 8 is rotatably connected inside the strip-shaped support 7. The first screw rod 8 is threadedly connected to the connecting seat 6. The connecting seat 6 passes through the opening 9 and is fastened to the bottom of the mounting box 4. The other end of the first screw rod 8 penetrates to the outside of the strip-shaped support 7 and is fastened with a second motor 14. The second motor 14 drives the first screw rod 8 to rotate. Due to the threaded connection and cooperation between the first screw rod 8 and the connecting seat 6, the connecting seat 6 can be driven to stably slide in the opening 9, thereby driving the mounting box 4 to slide on the top of the strip-shaped support 7.
[0025] At the same time, a first motor 5 is installed in the mounting box 4. The output end of the first motor 5 is rotatably connected to a connecting rod 13 in an L-shaped structure. A mounting seat 21 is fastened to the end of the connecting rod 13. The output end of the first motor 5 is fixedly connected to the mounting seat 21. The end of the connecting rod 13 is bent downward to be provided with an extension part 23. The extension part 23 moves into the connecting ring 10 under the drive of the first motor 5. The placing rack 11 is pulled out of the furnace body 1 under the pulling of the sliding mounting box 4. A plurality of conveying rollers 15 are rotatably arranged between the strip-shaped supports 7. The top of the conveying rollers 15 is on the same plane as the inner bottom surface of the furnace body 1. The placing rack 11 pulled out of the furnace body 1 can slide on the top of the conveying rollers 15, realizing the rapid blanking of workpieces.
[0026] To sum up, for the quenching furnace with a discharging function, during use, the present utility model further includes a control switch. The first motor 5, the second motor 14, and the third motor 18 are all connected to the control switch. Through the rotation of the third motor 18 and the cooperation of the driven wheel 20 and the mounting seat 21, the sliding adjustment of the fixing seat 16 on the second screw rod 17 is driven. At this time, the sealing door 2 moves upward. The second motor 14 rotates to drive the mounting box 4 and the first motor 5 to move to the feeding port of the furnace body 1. The first motor 5 controls the connecting rod 13 to rotate, so that the extension part 23 at its end moves into the connecting ring 10. The extension part 23 can clamp the placing rack 11. The second motor 14 rotates to drive the mounting box 4 and the first motor 5 to move in the reverse direction, so as to pull the placing rack 11 and the workpiece on its top out of the furnace body 1 and move them to the top of the conveying rollers 15. The placing rack 11 can slide on the top of the conveying rollers 15, realizing the rapid blanking of the workpieces in the furnace body 1. The present utility model not only facilitates the operation of the staff, but also can avoid the furnace body 1 from causing harm to the staff, improving the safety in use while facilitating blanking.
[0027] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
