Description
Technical Field
[0001] This utility model belongs to the technical field of industrial heating equipment, and in particular relates to a heat preservation mechanism for a medium-frequency forging furnace. Background Technology
[0002] With the continuous improvement of industrial manufacturing level, medium frequency forging furnaces, as key equipment in the metal processing process, have the core function of heating workpieces to a high temperature state, so that they can reach the ideal conditions for easy plastic deformation, thereby providing a good process foundation for subsequent forging, stamping and other processes. They are widely used in the fields of automobile, aerospace, and machinery manufacturing.
[0003] However, the feed inlet and discharge outlet of existing medium-frequency forging furnaces are usually directly exposed structures. During the heating process, a large amount of flue gas and high-temperature waste heat are generated. These flue gas and high-temperature waste heat are directly discharged into the working environment, which not only leads to the failure to effectively recover and utilize a large amount of waste heat resources, resulting in energy waste, but also easily causes problems such as high-temperature working environment, obstructed vision, and air pollution, posing a threat to the health and safety of on-site operators and affecting production efficiency and working comfort.
[0004] Therefore, there is a particular need for a medium-frequency forging furnace heat preservation mechanism to solve the above problems. Utility Model Content
[0005] In order to overcome the shortcomings of existing medium-frequency forging furnaces where the inlet and outlet are exposed, and flue gas and high-temperature waste heat are directly emitted during the heating process, resulting in energy waste and harming the working environment and personnel health, this utility model provides a medium-frequency forging furnace heat preservation mechanism.
[0006] This utility model is achieved through the following technical means: a medium-frequency forging furnace insulation mechanism, including a cabinet, a heating module, a heating tube, an insulation shell one, an insulation shell two, and a bracket one. The heating module is installed on the upper side of the cabinet, and the insulation shell one is installed on the upper part of the cabinet, with openings on both sides. The insulation shell two is fixed inside the insulation shell one, forming an inner and outer nested structure. The heating tube is installed inside the insulation shell two and electrically connected to the heating module. Two brackets one are arranged side by side and fixed to the inner top of the insulation shell two. It also includes a guide rod, a spring one, a cover plate, a pull rod, a spring two, and a wedge block. The upper part of the cabinet is fixed with a guide rod. Multiple guide rods are arranged in a rectangular pattern. A cover plate is slidably installed between every two guide rods that are laterally aligned. A spring 1 is sleeved on the outside of each guide rod. The two ends of the spring 1 are fixedly connected to the corresponding cover plate and the cabinet, respectively. A pull rod is slidably installed on the upper part of each cover plate. A spring 2 is sleeved on the end of each pull rod away from the insulation shell 1. The two ends of the spring 2 are fixedly connected to the corresponding cover plate and the corresponding pull rod, respectively. A wedge block is fixedly connected to the other end of each pull rod near the insulation shell 1. The inclined surface of the wedge block is aligned with the insulation shell 1. Wedge grooves are opened on both sides of the upper part of the insulation shell 1. The number of wedge blocks and wedge grooves is the same.
[0007] Furthermore, it also includes a second bracket, an electric slide rail, an electric carriage, an electric cylinder, and a top block. The second bracket is also installed on the upper part of the cabinet and located behind the first insulation shell. The electric slide rail is installed on the upper part of the cabinet, on which the electric carriage is slidably mounted. The electric cylinder is installed on the upper part of the electric carriage, with its piston rod extending forward and fixed to a top block. The shape of the top block matches the load-bearing space of the second bracket, and the bottom of the electric cylinder is higher than the bottom of the top block.
[0008] Furthermore, it also includes handles, with one handle installed on the side of each cover away from the insulation shell.
[0009] Furthermore, it also includes an air purifier, which is installed on the upper part of the insulation shell one, with its air intake end passing through the insulation shell one and extending into the interior of the insulation shell two.
[0010] Furthermore, it also includes slide rails, which are installed on one side of the cabinet.
[0011] Furthermore, the lowest point of the slide is close to the bottom of the cabinet.
[0012] Beneficial effects: 1. The nested structure of insulation shell one and insulation shell two achieves a double insulation effect, effectively reducing the loss of high-temperature residual heat, improving heating efficiency and energy utilization. At the same time, the cooperation of wedge block, spring two and wedge groove realizes the automatic locking of the cover plate, which tightly covers the opening of insulation shell one, forming a closed heating environment, enhancing the sealing performance, preventing the leakage of high-temperature residual heat, effectively inhibiting the diffusion of flue gas and heat into the working environment, improving working conditions, and ensuring the health of operators and production safety.
[0013] 2. Through the design of bracket II, electric slide rail, electric carriage, electric cylinder and top block, the workpiece feeding and unloading are automated, reducing manual intervention and improving operational safety.
[0014] 3. The air purifier is designed to handle the smoke and harmful gases generated during the heating process, improve the operating environment, and protect the health of operators. Attached Figure Description

[0020] A medium-frequency forging furnace heat preservation mechanism, such as Figures 1-4 As shown, the system includes a cabinet 1, a heating module 2, a heating tube 201, an insulation shell 3, an insulation shell 4, a bracket 5, and an air purifier 17. The heating module 2 is bolted to the upper left side of the cabinet 1. The insulation shell 3 is bolted to the upper part of the cabinet 1, with openings on its front and rear sides for workpiece entry and exit. The insulation shell 4 is fixedly connected inside the insulation shell 3, forming a nested structure for double insulation and improved insulation effect. The heating tube 201 is bolted to the inside of the insulation shell 4 and electrically connected to the heating module 2. Two brackets 5 are arranged side by side and fixedly connected to the inner top of the insulation shell 4. The air purifier 17 is bolted to the upper part of the insulation shell 3, with its air inlet passing through the insulation shell 3 and extending into the interior of the insulation shell 4. The system also includes a guide rod 6, a spring 7, a cover plate 8, a handle 9, a pull rod 10, a spring 11, and a wedge block 12. The upper part of the cabinet 1 is fixed. Four guide rods 6 are connected along a rectangular direction. A cover plate 8 is slidably installed between every two guide rods 6 that are laterally aligned. A handle 9 is bolted to the side of each cover plate 8 away from the insulation shell 3. A spring 7 is sleeved on the outside of each guide rod 6. The upper and lower ends of the spring 7 are fixedly connected to the corresponding cover plate 8 and the cabinet 1, respectively, to provide a reset force for the cover plate 8. A pull rod 10 is slidably installed on the upper part of each cover plate 8. A spring 11 is sleeved on the end of each pull rod 10 away from the insulation shell 3. The two ends of the spring 11 are fixedly connected to the corresponding cover plate 8 and the corresponding pull rod 10, respectively, to provide a reset force for the pull rod 10. A wedge block 12 is fixedly connected to the other end of each pull rod 10 near the insulation shell 3. The inclined surface of the wedge block 12 faces downward and is aligned with the insulation shell 3. Wedge grooves 121 are opened on both the front and rear sides of the upper part of the insulation shell 3. The number of wedge blocks 12 and wedge grooves 121 are the same.
[0021] like Figure 1 and Figure 4As shown, it also includes a bracket 13, an electric slide rail 14, an electric carriage 15, an electric cylinder 16, a top block 161, and a slide rail 18. The bracket 13 is also bolted to the upper part of the cabinet 1 and is located behind the insulation shell 3. The electric slide rail 14 is bolted to the upper part of the cabinet 1, and the electric carriage 15 is slidably mounted on it. The electric cylinder 16 is bolted to the upper part of the electric carriage 15, and its piston rod extends forward and is fixedly connected to the top block 161. The shape of the top block 161 matches the support space of the bracket 13, and it can slide into the support space of the bracket 13 to push the supported workpiece. The bottom of the electric cylinder 16 is higher than the bottom of the top block 161, and it can slide into the support space of the bracket 13 together. The slide rail 18 is bolted to the front side of the cabinet 1, and the lowest point of the slide rail 18 is close to the bottom of the cabinet 1, which facilitates guiding the pushed workpiece to the ground.
[0022] During use, the operator first places the workpiece to be heated on the bracket 13, then starts the electric slide rail 14, controls the electric slide 15 to drive the electric cylinder 16 forward, so that the top block 161 slides into the support space of the bracket 13, pushes the workpiece forward, enters the insulation shell 3, and is supported by the two brackets 5. At this time, the heating tube 201 surrounds the workpiece to provide energy for subsequent heating.
[0023] Next, grasp the handle 9 and pull down the cover plate 8. The cover plate 8 slides down along the guide rod 6, simultaneously moving the pull rod 10 down. As the cover plate 8 gradually covers the opening of the insulation shell 3, the spring 7 is compressed, and the inclined surface of the wedge block 12 contacts the insulation shell 3 and is subjected to outward squeezing force, causing the pull rod 10 to move outward. The spring 11 is stretched. When the cover plate 8 moves to completely cover the opening of the insulation shell 3, the wedge block 12 aligns with the wedge groove 121. Under the reset action of the spring 11, the pull rod 10 drives the wedge block 12 to move inward, so that it is inserted into the wedge groove 121, thereby locking the cover plate 8 and ensuring the sealing and heat preservation effect during the heating process.
[0024] Then, heating module 2 is started, and heating tube 201 heats the workpiece. At the same time, air purifier 17 is started to purify the smoke and harmful gases generated during the heating process and improve the air quality of the operating environment.
[0025] After heating is complete, turn off heating module 2 and air purifier 17, and pull rod 10 outward in sequence to drive wedge block 12 out of wedge groove 121. At this time, spring 7 releases the reset force and pushes cover plate 8 to slide upward. When wedge block 12 is displaced from wedge groove 121, release pull rod 10, and cover plate 8 resets under the action of spring 7, opening the opening of insulation shell 3.
[0026] Then, control the electric slide 15 again to drive the electric cylinder 16 to move forward, so that the top block 161 slides back into the bracket 13. Start the electric cylinder 16, control its piston rod to extend, drive the top block 161 to move forward and extend into the insulation shell 3, push the workpiece out of the insulation shell 3, and the pushed-out workpiece falls on the slide 18 and slides down the slide 18 to the ground.
[0027] Finally, the piston rod of the electric cylinder 16 retracts, causing the top block 161 to move backward. The electric slide 15 is then controlled to move the electric cylinder 16 backward back to the initial position, completing a full work cycle.
