Technical Field
[0001] This invention belongs to the field of waste heat utilization technology for metal castings, specifically relating to an integrated device for aging treatment of waste heat from metal castings. Background Technology
[0002] Metal castings are metal shaped objects obtained by various casting methods. That is, smelted liquid metal is poured into a pre-prepared mold by pouring, injection, suction or other casting methods, and after cooling, it is processed by grinding and other subsequent means to obtain an object with a certain shape, size and properties. Among them, aging treatment refers to the heat treatment process in which metal or alloy workpieces (such as low carbon steel) are placed at a high temperature or room temperature after solution treatment, high temperature quenching or a certain degree of cold working deformation, to maintain their shape, size and properties over time.
[0003] Existing metal casting manufacturing equipment releases a large amount of waste heat during the casting, cooling, and subsequent heat treatment processes. Traditional processes typically handle this heat through natural cooling or direct discharge, leading to energy waste and environmental pollution. At the same time, the castings require subsequent aging treatment. Since heating is required during aging treatment and the internal space of existing aging treatment chambers cannot be effectively adjusted, the heat transfer efficiency during the aging treatment of the castings is low, further increasing energy consumption. Utility Model Content
[0004] The purpose of this invention is to provide an integrated device for aging treatment of waste heat from metal castings, which can effectively convert and treat the waste heat generated during the metal casting process, and then transfer it to the treatment box for aging treatment; at the same time, by adjusting the space inside the treatment box, the heat dissipation inside the treatment box can be effectively ensured, reducing energy consumption.
[0005] The specific technical solution adopted by this utility model is as follows:
[0006] An integrated device for aging treatment of waste heat from metal castings includes a melting furnace, a sliding rail fixed to the bottom side inside the melting furnace, the sliding rail being slidably connected to the bottom of a support plate, and the top of the support plate being detachably connected to the casting mold.
[0007] The processing box has an opening for taking out and putting in on the side away from the smelting furnace, and multiple adjusting plates are slidably connected to both sides inside the processing box. Each of the multiple adjusting plates has a driving hole and an adjusting hole at both ends. The driving hole and the adjusting hole are slidably connected to the adjusting screw. A sliding groove is formed on the side of the multiple adjusting plates that are close to each other. The sliding groove is slidably connected to both sides of the placement plate. The placement plate has heat conduction holes.
[0008] The furnace has a heat exchanger fixed to its top, the bottom of which is connected to the top of the furnace, and one side of which is fixedly connected to the top of the processing box via a heat conduction pipe.
[0009] Furthermore, a drive cylinder is rotatably connected inside the drive hole, a drive ring is fixed at the bottom of the drive cylinder, and a drive tooth is fixed at the top of the drive cylinder.
[0010] Furthermore, an adjusting cylinder is rotatably connected inside the adjusting hole, and a driven tooth is fixed at the top of the adjusting cylinder. The driven tooth is connected to the transmission chain, and the transmission chain is connected to the drive tooth.
[0011] Furthermore, the plurality of adjusting screws are respectively threadedly connected to the drive cylinder and the adjusting cylinder.
[0012] Furthermore, the processing box has multiple scale markings on one side of the loading and unloading port, and the adjustment plate is adapted to the multiple scale markings.
[0013] Furthermore, a temperature sensor is fixed inside the heat exchanger, and a control valve is fixed at the connection between the heat exchanger and the heat conduction tube, the control valve being electrically connected to the temperature sensor.
[0014] The technical effects achieved by this utility model are as follows:
[0015] This utility model discloses an integrated device for aging treatment of waste heat from metal castings. By setting up a heat converter, it can effectively absorb the waste heat generated during the production of the smelting furnace and transfer it to the treatment box.

[0023] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific implementations of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.
[0024] like Figures 1 to 4 As shown, an integrated device for aging treatment of waste heat from metal castings includes a smelting furnace 10. A sliding rail 11 is fixed to the bottom side inside the smelting furnace 10. The sliding rail 11 is slidably connected to the bottom of a support plate 12. The top of the support plate 12 is detachably connected to the casting mold.
[0025] The processing box 20 has an opening for taking out and putting out on the side away from the melting furnace 10. Multiple adjusting plates 21 are slidably connected to both sides inside the processing box 20. The two ends of the multiple adjusting plates 21 are respectively provided with driving holes 211 and adjusting holes 212. The driving holes 211 and adjusting holes 212 are slidably connected to adjusting screws 22. A sliding groove 213 is provided on the side of the multiple adjusting plates 21 that is close to each other. The sliding groove 213 is slidably connected to both sides of the placement plate 23. Heat conduction holes are provided on the placement plate 23.
[0026] The smelting furnace 10 is equipped with a heat exchanger 30, the bottom of which is connected to the top of the smelting furnace 10, and one side of the heat exchanger 30 is fixedly connected to the top of the processing box 20 through a heat conduction pipe 31.
[0027] It should be noted that the melting furnace 10 is an electric arc furnace, which generates an electric arc by discharging electrodes inside, directly heating the metal to a liquid state. This liquid metal then drips into the casting mold, forming a metal casting. This is a conventional technique and will not be elaborated upon here. The sliding rail 11 and support plate 12 inside the melting furnace 10 can effectively move the casting mold to a designated position, thereby effectively receiving the liquid metal and ensuring the formation of a complete metal casting. The treatment box 20 can effectively age the formed metal casting, ensuring stable casting dimensions, stable stress release, and improved hardness and wear resistance. Specifically, by setting a heat exchanger 30 at the top of the melting furnace 10, the residual heat (300-600℃) of the casting in the melting furnace 10 is effectively converted into the heat energy required by the aging treatment box 20 through heat exchange, realizing the cascade utilization of energy. This is a conventional technique and will not be elaborated upon here.
[0028] like Figure 3 , Figure 4 As shown, a drive cylinder 24 is rotatably connected inside the drive hole 211. A drive ring is fixed at the bottom of the drive cylinder 24, and a drive tooth is fixed at the top of the drive cylinder 24.
[0029] like Figure 3 , Figure 4 As shown, an adjusting cylinder 25 is rotatably connected inside the adjusting hole 212. A driven tooth is fixed on the top of the adjusting cylinder 25. The driven tooth is connected to the transmission chain 26, and the transmission chain 26 is connected to the drive tooth.
[0030] Preferably, the plurality of adjusting screws 22 are threadedly connected to the drive cylinder 24 and the adjusting cylinder 25 respectively.
[0031] In the above embodiments, it should be noted that the drive cylinder 24, the adjusting cylinder 25, and the transmission chain 26 are all made of high-temperature resistant metal. When it is necessary to adjust the space inside the processing box 20, by rotating the drive cylinder 24, the transmission chain 26 can be effectively driven by the drive teeth set at the top, and the driven chain 26 can synchronously drive the driven teeth on the adjusting cylinder 25, so that the adjusting cylinder 25 and the drive cylinder 24 rotate synchronously. Then, the drive cylinder 24 and the adjusting cylinder 25 synchronously interact with the adjusting screw 22 to adjust the adjusting plate 21, ensuring that the placing plate 23 is raised and lowered by the adjusting plates 21 on both sides, so that the processing box 20 can effectively accommodate products of different sizes. Specifically, the placing plate 23 is provided with heat conduction holes, which can effectively ensure the heat dissipation inside the processing box 20, ensure that the internal temperature is kept uniform, and prevent temperature differences.
[0032] like Figure 2 As shown, the processing box 20 has multiple scale markings on one side of the loading and unloading port, and the adjustment plate 21 is adapted to the multiple scale markings.
[0033] In this embodiment, based on the previous embodiment, when the adjustment plate 21 moves, the distance between two adjacent adjustment plates 21 can be calculated by corresponding to the scale markings, so as to accurately adjust the distance and avoid the large distance between two adjacent adjustment plates 21, which would waste the internal space of the processing box 20. At the same time, it can also avoid the problem that the distance between two adjacent adjustment plates 21 is too small, which would cause the casting to be crowded, resulting in low heat conduction efficiency, uneven energy distribution, and increased energy consumption.
[0034] Preferably, a temperature sensor is fixed inside the heat exchanger 30, and a control valve 301 is fixed at the connection between the heat exchanger 30 and the heat conduction pipe 31. The control valve 301 is electrically connected to the temperature sensor. It should be noted that the temperature sensor can be set according to the usage requirements. When the temperature reaches the set temperature, the control valve 301 will open, thereby converting the heat energy in the heat exchanger 30 and transferring it to the processing box 20 through the heat conduction pipe 31. When the residual heat temperature of the smelting furnace 10 is higher or lower than the set temperature, the control valve 301 is in the closed state, which can effectively prevent excessively high or low temperatures from damaging the castings inside the processing box 20. This is a conventional technical means and will not be described in detail here.
[0035] The working principle of this utility model is as follows: The mold is placed on the support plate 12, and the support plate 12 is pushed along the sliding rail 11 to move the mold to a designated position inside the melting furnace 10. Subsequently, by starting the melting furnace 10, a large amount of residual heat is generated during the metal casting process. This residual heat is effectively absorbed by the heat exchanger 30 and then transferred to the treatment box 20. The treatment box 20 effectively ages the finished casting, thereby improving the hardness and wear resistance of the metal casting and reducing the risk of deformation and cracking during subsequent processing or use. This design improves practical accuracy and lifespan. Specifically, by rotating the drive cylinder 24, the adjustment cylinder 25 is effectively driven to rotate via the transmission chain 26. This allows for synchronous threaded action with the adjustment screw 22 inside the processing box 20, enabling the adjustment plate 21 to be raised and lowered. The adjustment plates 21 on both sides then coordinate with the placement plate 23 and the scale markings, allowing for precise adjustment of the internal space. This avoids insufficient space or unreasonable space utilization when placing metal castings. At the same time, it prevents collisions and friction between metal castings, reducing safety hazards during the use of the processing box 20.
[0036] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
