Description

Technical Field

[0001] This utility model relates to the field of metal processing technology, specifically to a quenching furnace for metal processing with a protective structure. Background Technology

[0002] To produce metal workpieces with higher hardness, the workpieces are often heated in a furnace and then quenched to improve their hardness and surface finish.

[0003] When using a belt quenching furnace, the workpiece needs to be placed manually on the conveyor belt at the front. Since the conveyor belt is at a high temperature after passing through the quenching furnace, the workpiece will inevitably come into contact with the high temperature of the conveyor belt when being placed, which will cause skin burns, resulting in physical injury and affecting the normal work of the workers. In severe cases, it may even prevent them from continuing to work, greatly reducing the workers' work efficiency.

[0004] For example, the novel quenching furnace for metal heat treatment disclosed in Chinese patent CN220265744U, when the quenching furnace is heated to a high temperature via a conveyor belt, the heat is blown onto the upper and lower surfaces by a cooling fan after exiting the furnace. Then, it passes through the bottom of the water tank via a limiting roller and achieves rapid cooling under the action of cooling water. After that, the cooling water is removed by a cleaning roller. Under the dual cooling of air cooling and water cooling, the conveyor belt can be cooled down quickly.

[0005] However, in existing technologies, when using conveyor belts to load and unload metal workpieces, the stability of the workpieces cannot be guaranteed well, and the temperature of the workpieces after processing is relatively high, which can easily lead to danger.

[0006] Therefore, we urgently need to provide a quenching furnace for metal processing with a protective structure. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1:

[0027] In existing technologies using conveyor belts for loading and unloading metal workpieces, the stability of the workpieces cannot be guaranteed effectively. Furthermore, the relatively high temperature of the workpieces after processing can easily lead to dangerous situations. Please refer to [the relevant documentation / reference]. Figures 1-4The embodiment provides a metal processing quenching furnace with a protective structure, which can effectively improve the stability of the workpiece during loading and unloading. The metal processing quenching furnace with a protective structure includes a furnace body 1, a loading and unloading device installed inside and at the bottom of the furnace body 1, a switch device installed at the right end of the front of the furnace body 1, and heat dissipation devices provided at the bottom and top of the front of the furnace body 1.

[0028] The loading and unloading device includes a loading and unloading structure and an auxiliary limiting structure, with the auxiliary limiting structure installed on top of the loading and unloading structure. The loading and unloading structure includes a fixed plate 101, with an adjusting motor 102 mounted on the back of the fixed plate 101. An adjusting component 103 is connected to the output end of the adjusting motor 102. A connecting plate 104 is connected to the outer surface of the adjusting component 103, and a loading plate 105 is connected to the top of the connecting plate 104. A protective plate 106 is installed on the top surface of the loading plate 105. The auxiliary limiting structure includes a limiting rod 107, with a guide rod 108 slidably connected to the outer surface of the limiting rod 107. The bottom surface of the guide rod 108 is fixedly connected to the inner bottom surface of the furnace body 1.

[0029] The top of the fixed plate 101 is fixedly connected to the bottom of the furnace body 1. The adjusting motor 102 is detachably installed at the bottom of the furnace body 1. The top of the limiting rod 107 is fixedly connected to the bottom surface of the feeding plate 105. The outer surface of the limiting rod 107 is slidably connected to the inner wall of the convex sliding groove in the middle of the top surface of the guide rod 108. A groove adapted to the size of the connecting plate 104 is provided in the middle of the bottom end of the front of the furnace body 1.

[0030] By setting up the loading and unloading device, the adjusting motor 102 drives the adjusting component 103 to drive the loading plate 105 and the protective plate 106 to load and unload, and the protective plate 106 installed on the top of the loading plate 105 ensures the stability of the workpiece during the loading and unloading process.

[0031] When loading and unloading workpieces, the workpieces are placed on the top surface of the loading plate 105. Then, the regulating motor 102 is started to drive the regulating component 103 for transmission. The output end of the regulating motor 102 drives the threaded rod to rotate. The outer surface of the threaded rod is threaded with a threaded cylinder. The outer surface of the threaded cylinder is fixedly connected to the connecting plate 104. Thus, the connecting plate 104 drives the loading plate 105 to move. At the same time, the sliding connection between the limiting rod 107 and the inner wall of the convex groove on the top surface of the guide rod 108 limits the movement of the loading plate 105. During the loading and unloading process, the protective plate 106 can effectively prevent the risk of the workpieces slipping. In addition, a groove that matches the size of the connecting plate 104 is opened in the middle of the bottom front of the furnace body 1, which will not hinder the closing of the furnace door 205 after loading.

[0032] Example 2:

[0033] Based on Implementation 1, the existing technology still has the problem that when the furnace is turned on after processing, a heat wave will surge out, which may cause injury to workers. Please refer to [link / reference needed]. Figures 1-4This embodiment provides a metalworking quenching furnace with a protective structure, which can effectively solve the danger to workers when opening the furnace. The metalworking quenching furnace with the protective structure includes a switching device comprising an asynchronous motor 201. A transmission component 202 is connected to the output end of the asynchronous motor 201. A rotating shaft 203 is mounted in the middle of the transmission component 202. A connecting rod 204 is fixedly connected to the outer surface of the rotating shaft 203. A furnace door 205 is fixedly connected to the outer surface of the connecting rod 204. A fixed rod 206 is rotatably connected to the outer surface of the rotating shaft 203. The asynchronous motor 201 is detachably connected to the top right side of the furnace body 1 near the front. The end of the connecting rod 204 near the rotating shaft 203 is slidably connected to the outer surface of the fixed rod 206. The end of the fixed rod 206 away from the rotating shaft 203 is fixedly connected to the furnace body 1.

[0034] The heat dissipation device includes a cooling box 301. A liquid inlet pipe 302 is installed in the middle of the left side of the cooling box 301. A mounting plate 303 is provided on the top of the cooling box 301, and a fan 304 is installed in the middle of the mounting plate 303. The liquid inlet pipe 302 is installed inside a round hole in the middle of the left side of the cooling box 301 near the top. The mounting plate 303 is fixedly installed on one end of the front top of the furnace body 1. The fan 304 is installed inside a rectangular hole in the mounting plate 303.

[0035] By setting up a switching device and a heat dissipation device, the asynchronous motor 201 is started to drive the transmission component 202 and the rotating shaft 203 to open and close the furnace door 205, and the fan 304 is used to blow hot air, thereby effectively reducing the heat wave that may cause harm to the staff when the door is opened.

[0036] When processing the workpiece, the asynchronous motor 201 is started to drive the transmission component 202. The output end of the asynchronous motor 201 drives the worm to rotate. A worm wheel is meshed on the outer surface of the worm. The middle part of the worm wheel is connected to the rotating shaft 203 near the top, thereby driving the rotating shaft 203 to rotate. When the rotating shaft 203 rotates, it drives the connecting rod 204 and the furnace door 205 to rotate. At the same time, the fixed rod 206 is connected to the rotating shaft 203 to rotate and close or open the furnace door 205, effectively preventing the furnace door 205 from overheating and causing injury to the staff. When the furnace door 205 is open, the fan 304 is started to blow the heat dissipated from the furnace body 1 upward, reducing the heat wave from escaping and causing injury to the staff. At the same time, the cooling medium stored in the cooling box 301 is used to facilitate the cooling process for the staff.
