Description

Technical Field

[0001] The utility model relates to the technical field of heating furnaces, in particular to a layered forging heating furnace. Background Art

[0002] During the production and processing of forgings, they need to be heated before forging, so a corresponding heating furnace is needed to introduce the forgings into the heating furnace for sufficient heating, so that the shaping effect of the workpiece during forging and shaping is better;

[0003] In actual use of the existing heating furnace, the forgings are directly introduced into the conveyor belt of the heating furnace, and then the conveyor belt is used to drive the forgings to move slowly in the heating furnace, so as to heat the heating furnace. However, the forgings are directly introduced into the furnace for heating, which does not have the function of preheating, so the heating effect is not good, and more heat energy is required for heating, which causes energy waste, and the heating speed is slow, affecting efficiency. Therefore, we propose a layered forging heating furnace. Utility Model Content

[0004] The utility model aims to provide a layered forging heating furnace to solve the problems raised in the background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a layered forging heating furnace, comprising a furnace body, a conveyor belt is installed on the lower side of the inner cavity of the furnace body, one end of the conveyor belt movably passes through a discharge port opened on one side of the furnace body, a feed port is opened on the upper side of one side wall of the furnace body and a first material guide plate is installed in the feed port, a second material guide plate is installed on the lower side of the first material guide plate, an exhaust fan is fixed to one side wall of the furnace body, one end of the exhaust fan passes through the furnace body through a pipeline and is fixedly connected to an air collecting hood, the other end of the exhaust fan is fixedly connected to a first duct, the outer end of the first duct passes through the top of the furnace body and is fixedly connected to a first gas distribution plate, the bottom of the first guide plate is fixed to a second gas distribution plate, the outer wall of the first duct is fixedly connected to a second duct, and the outer end of the second duct passes through the furnace body and is connected to the second gas distribution plate.

[0006] By adopting the above technical solution, the forgings to be heated are placed on the first guide plate, so that the forgings slide along the inclined first guide plate. At this time, the exhaust fan draws the hot air from the heating furnace on the lower side of the furnace body, leading to the first gas distribution plate and the second gas distribution plate, so as to use the hot air derived from the first gas distribution plate and the second gas distribution plate to preheat the forgings on the first guide plate and the second guide plate, and then slide them onto the conveyor belt, heat them in the process of the conveyor belt driving the forgings to move, and lead them out of the furnace body after the heating is completed, so as to preheat them first and then heat them, which reduces the energy consumption of heating and also improves the heating efficiency.

[0007] As a preferred embodiment of the utility model, a cross plate is provided at the tail end of the first material guide plate, a short shaft is fixed to the inner end of the cross plate, the outer end of the short shaft is rotatably connected to the inner wall of the furnace body, and a torsion spring is fixedly sleeved on the outer wall of the short shaft.

[0008] By adopting the above technical solution, when the forging slides from the first guide plate to the second guide plate, the forging will fall onto the cross plate. At this time, the cross plate will rotate. After rotating to a certain angle, the forging will slide onto the second guide plate. At the same time, the torsion spring will drive the short shaft to rotate, thereby rotating the cross plate, and then the cross plate will pick up the sliding forging, so that the forging turns over and falls onto the surface of the second guide plate, so that the forging after turning over is preheated again on the second guide plate, thereby improving the preheating effect.

[0009] As a preferred embodiment of the utility model, a servo motor is fixed on the back of the furnace body in the middle of the side walls corresponding to the first material guide plate and the second material guide plate. The transmission shaft of the servo motor passes through the furnace body and is fixedly connected to the middle of the side walls of the corresponding first material guide plate and the second material guide plate.

[0010] By adopting the above technical solution, when the first guide plate and the second guide plate guide the forging, the servo motor can be used to drive the first guide plate and the second guide plate to rotate and change the inclination angle, so that the sliding speed can be adjusted for forgings of different sizes, thereby ensuring sufficient preheating and then ensuring the subsequent heating effect.

[0011] As a preferred embodiment of the present invention, the inner side wall of the first gas distribution plate is fixedly connected to the inner wall of the furnace body.

[0012] By adopting the above technical solution, the stability of the first gas distribution disk during use can be ensured.

[0013] As a preferred embodiment of the present invention, the inner side walls of the first material guide plate and the second material guide plate are arranged in contact with the inner wall of the furnace body.

[0014] By adopting the above technical solution, the first material guide plate and the second material guide plate can be ensured to rotate stably.

[0015] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0016] The layered forging heating furnace of the technical solution of the present application guides the forgings through the first guide plate and the second guide plate. When guiding the forgings, the exhaust fan is used to extract the heat from the lower side of the heating furnace and guide it to the first air distribution plate and the second air distribution plate, so that the forgings can be preheated. The preheated workpiece slides onto the conveyor belt for mobile heating, so that the heating sufficiency of the forgings can be ensured. At the same time, preheating is performed before heating, which improves the heating efficiency.

[0017] The servo motor can drive the first guide plate and the second guide plate to slightly rotate a certain angle, so that the tilt angle can be adjusted for forgings of different sizes, and then the sliding speed of the forgings can be adjusted, so as to ensure that different forgings can be preheated for different times, ensure the preheating effect, and then ensure the heating effect of the forgings;

[0018] A cross plate is provided at the tail end of the first guide plate, so that when the forging falls from the first guide plate to the second guide plate, it can first impact on the cross plate, and the cross plate will rotate. After rotating to a certain angle, the forging slides downward, and at the same time, the cross plate is driven to rotate under the action of the torsion spring, so that the forging can be picked up and turned over, so that the forging can be preheated on the second guide plate after being turned over, thereby further improving the preheating effect.

[0028] In actual use, the forgings to be heated are placed on the first guide plate 11, so that the forgings slide along the inclined first guide plate 11. At this time, the exhaust fan 2 will extract the hot air from the heating furnace at the lower side of the furnace body 1 to the first gas distribution plate 23 and the second gas distribution plate 25, so as to preheat the forgings on the first guide plate 11 and the second guide plate 12 by using the hot air extracted from the first gas distribution plate 23 and the second gas distribution plate 25, and then slide to the conveyor belt 13, and heat the forgings in the process of being driven by the conveyor belt 13. After heating, the forgings are led out of the furnace body 1, so as to preheat first and then heat, thereby reducing the energy consumption of heating and improving the heating efficiency.

[0029] Furthermore, a servo motor 14 is fixed at the middle of the side wall corresponding to the first guide plate 11 and the second guide plate 12 on the back of the furnace body 1. The transmission shaft of the servo motor 14 penetrates the furnace body 1 and is fixedly connected to the middle of the side wall of the corresponding first guide plate 11 and the second guide plate 12. Therefore, when the first guide plate 11 and the second guide plate 12 guide the forging, the servo motor 14 can be used to drive the first guide plate 11 and the second guide plate 12 to rotate and change the inclination angle, so that the sliding speed can be adjusted for forgings of different sizes, thereby ensuring sufficient preheating and subsequent heating effect.

[0030] Furthermore, the inner side walls of the first guide plate 11 and the second guide plate 12 are arranged to fit the inner wall of the furnace body 1, thereby ensuring the first guide plate 11 and the second guide plate 12 to rotate stably;

[0031] It is worth mentioning that the inner side wall of the first gas distribution plate 23 is fixedly connected to the inner wall of the furnace body 1, so as to ensure the stability of the first gas distribution plate 23 during use;

[0032] like Figure 1 and 3As shown; a cross plate 3 is provided at the tail end of the first guide plate 11, a short shaft 31 is fixed to the inner end of the cross plate 3, the outer end of the short shaft 31 is rotatably connected to the inner wall of the furnace body 1, and a torsion spring 32 is fixedly sleeved on the outer wall of the short shaft 31;

After rotating to a certain angle, the forging will slide onto the second guide plate 12. At the same time, the torsion spring 32 will drive the short shaft 31 to rotate, thereby rotating the cross plate 3, and then the cross plate 3 will pick up the sliding forging, so that the forging will turn over and fall onto the surface of the second guide plate 12, so that the forging after turning over can be preheated again on the second guide plate 12, thereby improving the preheating effect.

[0034] The implementation principle of a layered forging heating furnace of the present application is as follows: in actual use, when the first guide plate 11 and the second guide plate 12 guide the forgings, the servo motor 14 can be used to drive the first guide plate 11 and the second guide plate 12 to rotate and change the tilt angle, so that the sliding speed can be adjusted for forgings of different sizes, and the forgings to be heated are placed on the first guide plate 11, so that the forgings slide along the tilted first guide plate 11. At this time, the exhaust fan 2 will extract the hot air from the heating furnace on the lower side of the furnace body 1, leading to the first gas distribution plate 23 and the second gas distribution plate 25, so as to preheat the forgings on the first guide plate 11 and the second guide plate 12 using the hot air extracted from the first gas distribution plate 23 and the second gas distribution plate 25. When the forging slides from the first guide plate 11 to the second guide plate 12, the forging will fall onto the cross plate 3. At this time, the cross plate 3 will rotate. After rotating to a certain angle, the forging will slide onto the second guide plate 12. At the same time, the torsion spring 32 will drive the short shaft 31 to rotate, so that the cross plate 3 rotates, and then the cross plate 3 will pick up the sliding forging, so that the forging is turned over and falls onto the surface of the second guide plate 12, so that the turned over forging is preheated again on the second guide plate 12, thereby improving the preheating effect, and then slides to the conveyor belt 13, and is heated in the process of the conveyor belt 13 driving the forging to move. After the heating is completed, it is led out of the furnace body 1, thereby preheating first and then heating, reducing the energy consumption of heating, and also improving the heating efficiency.
