Description

Technical Field

[0001] This utility model relates to the field of flange manufacturing technology, and in particular to a heating device for manufacturing flanges. Background Technology

[0002] In the heat treatment process of flange manufacturing, existing technologies have significant drawbacks. On the one hand, heating methods are mostly limited to unidirectional heating, such as providing a heat source only through a bottom heating platform or side heating pipe assembly. This design easily creates obvious heating blind spots on the flange surface: when bottom heating is used, the top and circumferential edges of the flange are not heated enough, resulting in a temperature difference of tens of degrees Celsius between the top and bottom; when side heating is used, heat transfer in the central area of ​​the flange is slow, and temperature differences occur at different circumferential locations due to varying distances from the heating source. Such excessive temperature differences can cause uneven thermal stress distribution in subsequent processing, leading to quality defects such as deformation and cracks, seriously affecting the mechanical properties and service life of the product.

[0003] On the other hand, the design of the suspension mechanism has obvious limitations. The suspension structure of most devices is fixed inside the heating chamber. When operators load or unload workpieces, they have to put their hands or tools into the high-temperature heating environment, which is not only cumbersome and inefficient, but also poses a safety risk of burns. At the same time, the size and load-bearing method of the traditional suspension mechanism are fixed and cannot be flexibly adjusted according to the diameter, thickness and other specifications of the flange. It is difficult to adapt to the batch heating needs of different batches and models of flanges, resulting in a significant reduction in the equipment's versatility and production efficiency, making it difficult to meet the diversified and mass production requirements of modern flange manufacturing.

[0004] Therefore, it is necessary to develop a heating device for manufacturing flanges to address the aforementioned shortcomings. Utility Model Content

[0005] The purpose of this invention is to provide a heating device for manufacturing flanges, which enables uniform heating of the flanges, facilitates loading and unloading, and improves efficiency and quality.

[0014] Preferably, the bottom of the furnace door has two grooves that match the electric track, covering the top of the electric track; a sealing strip is embedded in the inner side of the groove, and the sealing strip is in close contact with the surface of the electric track.

[0015] Preferably, the heating elements are evenly distributed below the heating platform and electrically connected to the controller.

[0016] Preferably, the heating tube assembly consists of heating tubes arranged in four concentric circles from top to bottom along the vertical direction, with four tubes evenly distributed in each circle, and uniformly distributed around the inner side of the heating cavity in a ring array; each heating tube is electrically connected to the controller.

[0017] Preferably, there are two ultrasonic temperature measurement modules, symmetrically arranged on the inner wall of the heating cavity, for all-round monitoring of the temperature distribution inside the heating cavity.

[0018] Preferably, the central support rod of the suspension frame assembly is driven by a rotary motor, which is electrically connected to the controller.

Therefore, they should not be construed as limitations on this utility model. Specific Implementation

[0035] like Figure 1-4 As shown, a heating device for manufacturing flanges includes:

[0036] Heating chamber 1 is a one-piece molded box structure made of high-temperature resistant, high-strength alloy material. Its interior contains a heating chamber 101 to provide a closed heating space. The inner wall of the heating chamber 101 is uniformly covered with a high-temperature resistant heat insulation layer to reduce heat loss and maintain a constant temperature environment within the chamber. A sealable furnace door 102 is located on one side of the heating chamber 1. The furnace door 102 is hinged to the heating chamber 1 by multiple sets of high-strength hinges and is equipped with a quick-locking sealing mechanism to ensure a tight seal between the furnace door and the heating chamber, preventing heat leakage and the intrusion of cold air during heating. Simultaneously, a high-temperature resistant observation window is embedded in the surface of the furnace door, allowing operators to observe the heating status of the workpiece inside the heating chamber in real time without opening the furnace door.

[0037] Heating mechanism 2, located inside heating chamber 101, employs a three-dimensional heating design and consists of heating platform 201, heater 202, and heating tube assembly 203. Heating platform 201 is positioned at the bottom of heating chamber 101 and connected to heating element 204, which provides the heat source, via a high-temperature resistant heat-conducting plate. Its surface is equipped with uniformly distributed heat-conducting grooves, enabling rapid and even heat transfer to the bottom of the flange, achieving omnidirectional uniform heating. Heater 202 is installed at the top of heating chamber 101 and utilizes a high-precision temperature control system to precisely heat the top of the flange according to a preset temperature curve. Heating tube assembly 203 is arranged around the inner side of heating chamber 101, providing circumferential three-dimensional heating of the flange, ensuring uniform heating of all parts of the flange and eliminating heating blind spots.

[0038] The suspension bracket assembly 4, located above the heating platform 201, serves as a key load-bearing and transmission structure during the heating process of the flange forging. Its design fully considers the requirements for uniform heating of the forging and convenient operation. This assembly mainly consists of a central support rod 401, a rotary motor 402 providing rotational power, and a multi-layered arrangement structure.

[0039] The rotary motor 402 is a high-torque servo motor, rigidly connected to the central support rod 401 via a high-precision reducer. It can drive the central support rod 401, thereby driving the multi-layer placement rack to perform stable rotational motion. This rotational design ensures that the flange forgings placed on the placement rack can be heated evenly in all directions during the heating process, effectively avoiding quality defects such as deformation and cracks caused by uneven local heating.

[0040] The multi-layer display rack adopts a modular design. Its base 403 is fixed to the central support rod 401 with high-strength bolts, allowing for quick assembly and disassembly to adjust the number of layers according to flange size requirements. Multiple placement rods 404 are annularly hinged to the periphery of the base 403. Each placement rod 404 has an inverted U-shaped notch 405, and the surface of the notch is inlaid with a high-temperature resistant silicone pad. This not only stably places flange forgings of different specifications but also prevents scratches on the surface of the forgings during rotation.

[0041] The suspension assembly 4 is connected to the heating box 1 via the moving assembly 7. When the flange forging needs to be moved, the moving assembly 7 can precisely control the suspension assembly 4 to feed the forging from the feed port into the heating platform 201, and after heating, it is moved to the discharge port. Combined with the rotary heating function, a complete automated processing flow is formed.

[0042] The movable component 7 has an ingenious structural design and complete functions. Part of it is located on the inner side of the bottom of the heating box 1 and part of it extends to the outside of the heating box 1. It mainly consists of an electric track 701 that plays a guiding role, a drive motor 702 that provides driving power, a sliding slider 703, and a support 704 that plays a load-bearing and connecting role.

[0043] The electric track 701 is made of high-strength alloy steel to ensure stability during movement. It is fixedly installed at the bottom and external extension area of ​​the heating box 1, and is tightly connected to the pre-set mounting base at the bottom of the heating box 1 using high-strength bolts, providing a stable and precise movement path for the suspension assembly 4. This track has a linear motion guiding function, effectively preventing the suspension assembly from shifting or swaying during movement.

[0044] The slider 703 uses a high-precision linear bearing slider with a self-lubricating bearing inside, which can achieve low friction and long service life. Two sliders 703 with the same structure are slidably embedded on two electric rails 701 through a precision fitting process, ensuring that the sliders 703 can slide smoothly on the rails, while having good load-bearing capacity to support the weight of the suspension frame assembly 4 and the workpiece.

[0045] The bracket 704 is welded from high-strength aluminum alloy profiles and undergoes stress relief treatment to ensure structural stability and reliability. Both ends of the bracket 704 are rigidly connected to two sliders 703 via bolts and locating pins, ensuring a stable and accurate connection. A rotary motor 402 is fixedly mounted on the upper surface of the middle section of the bracket 704 using a dedicated motor mounting bracket. This bracket not only supports the suspension assembly 4 but also stably transmits the power from the drive motor 702 to the suspension assembly 4, ensuring its smoothness during movement.

[0046] The drive motor 702 and the slider 703 are connected by a high-precision ball screw transmission mechanism, which has the advantages of high transmission efficiency, smooth movement, and accurate positioning. Through the precise control of the drive motor 702 by the servo control system, the slider 703 can move precisely along the electric track 701, thereby realizing the automatic entry and exit of the suspension frame assembly 4, meeting the usage requirements under different working conditions, and the movement speed and position can be flexibly adjusted according to actual needs.

[0047] The controller (PLC control system) 3 uses a high-performance microprocessor as its core control unit, integrating multi-channel data processing modules and intelligent algorithms. It is installed on the outer wall of the heating chamber 1 via an embedded control system to achieve centralized control of the operating status of each component. A high-precision ultrasonic temperature measurement module 301 is installed on the inner wall of the heating chamber 1, utilizing the characteristics of ultrasonic wave propagation speed in different temperature media to monitor the three-dimensional spatial temperature field within the heating cavity 101 in real time. The controller 3 incorporates a PID temperature control algorithm, dynamically adjusting the operating power of the heating tube group 203 in the heating mechanism 2 based on the temperature data fed back by the ultrasonic temperature measurement module 301. Furthermore, the controller 3 establishes bidirectional communication connections with the heating mechanism 2, the ultrasonic temperature measurement module 301, the suspension assembly 4, and the moving assembly 7, respectively. It is equipped with an automated control program to achieve fully automated control of the entire process, including heating, temperature measurement, and component movement. It also features fault diagnosis and alarm functions, automatically triggering a shutdown protection mechanism in case of system abnormalities.

[0048] The electric track 701 consists of two parallel tracks laid along the entry and exit direction of the suspension frame assembly 4. It extends through the interior and exterior of the heating chamber 1, with its inner side located at the bottom of the heating cavity 101 and its outer side extending to below the furnace door 102 outside the heating chamber 1, forming a complete and smooth entry and exit channel. The electric track 701 is driven by a drive motor 702 and electrically connected to the controller 3, enabling precise movement in response to control commands. The slider 703 is connected to the suspension frame assembly 4 via a bracket 704 and can slide smoothly along the electric track 701, ensuring stability during flange transfer.

[0049] Two symmetrically distributed grooves 103 are formed at the bottom of the furnace door 102 along the running direction of the electric track 701. The cross-section of the grooves 103 is an inverted U-shape, and the depth is precisely controlled to completely cover the height of the top flange of the electric track 701. This dimensional fit ensures that the electric track 701 will not mechanically interfere with the bottom of the furnace door 102 during closing, while also forming a stable guiding structure. The inner wall of the grooves 103 is fitted with a high-temperature resistant silicone rubber sealing strip using a dovetail groove structure. This sealing strip is specially formulated to maintain good elasticity at a high temperature of 800℃, and its cross-section is designed with a serrated wave structure. When the furnace door 102 is closed, the sealing strip, under its own elasticity and the pressure of the door body, forms multiple sealing contact surfaces with the surface of the electric track 701. Together with the high-temperature resistant sealing strip at the edge of the heating chamber 101, it constitutes a double sealing protection system.

[0050] The heating platform 201 is made of a metal with excellent thermal conductivity and its surface is anodized to form a dense oxide film, effectively improving corrosion resistance and heat transfer efficiency, enabling rapid heat transfer and uniform distribution across the entire working surface. Heating elements 204 are evenly distributed within a thermally conductive silicone layer beneath the heating platform 201 and are electrically connected to the controller 3 via high-temperature resistant wires. The heater 202 uses a third-generation short-wave infrared heating device with a built-in gold-plated reflective layer and intelligent power adjustment chip. Its heating power can be adjusted via the touchscreen of the controller 3. Combined with an infrared temperature feedback system, it can meet diverse heating needs such as stepped heating and constant temperature for flanges of different specifications.

[0051] The heating tube assembly 203 consists of heating tubes 2031, which are precisely arranged in four concentric rings vertically from top to bottom, with four tubes evenly distributed in each ring. These tubes are uniformly distributed around the inner side of the heating chamber 101 in a circular array. This three-dimensional layout, combined with the staggered installation angles, creates a spiral heat flow circulation during flange heating. Each heating tube 2031 is equipped with an independent PTC intelligent temperature control module, which communicates bidirectionally with the controller 3 via a high-temperature resistant cable. The controller 3 presets heating programs to achieve stepped heating process requirements, meeting the heat treatment process requirements of flanges of different specifications.

[0052] Two ultrasonic temperature measurement modules 301 are provided, symmetrically arranged on the inner wall of the heating cavity, which can monitor the temperature distribution in the heating cavity 101 and provide accurate temperature data reference for the controller 3.

[0053] The central support rod 401 of the suspension bracket assembly 4 is driven by a rotary motor 402. The rotary motor 402 is electrically connected to the controller 3. The controller 3 intelligently controls the speed and direction of rotation of the rotary motor 402 according to the temperature distribution in the heating chamber 101, so that the flange is heated more evenly.

[0054] An energy-saving waste heat recovery assembly 5 is also installed on the top of the heating box 1. The waste heat recovery assembly 5 is sealed to the exhaust port on the top of the heating box 1 through a high-temperature and corrosion-resistant exhaust pipe 501. The exhaust pipe 501 adopts a double-layer heat insulation structure, which can effectively reduce heat loss during the transmission process. The waste heat recovery assembly 5 can efficiently recover the heat in the exhaust gas, realizing the secondary utilization of energy. The waste heat recovery assembly 5 includes a high-efficiency spiral finned heat exchanger 502 and a preheating chamber 503 for preheating. The spiral finned heat exchanger 502 is made of high-efficiency thermally conductive material, and its unique spiral fin structure greatly increases the heat exchange area and significantly improves the heat exchange efficiency. The air inlet end of the heat exchanger 502 is connected to the other end of the exhaust pipe 501, and the air outlet end of the heat exchanger 502 is connected to the air inlet end of the preheating chamber 503. The other end of the preheating chamber 503 is connected to the exhaust gas purification assembly 6. A side door equipped with a safety locking mechanism and a high-temperature resistant sealing strip is also provided on one side of the preheating chamber 503 for easy access to the flange by the operator. The preheating chamber 503 is used to preheat the flange forgings to be placed into the heating box 1. By preheating the temperature of the forgings, the subsequent heating time can be shortened, energy consumption can be reduced, and production efficiency can be improved.

[0055] The top of the heating chamber 1 is also equipped with an environmentally friendly waste gas purification component 6. This component adopts a multi-stage purification structure design, which includes a dry filter layer, an activated carbon adsorption module, a photocatalytic oxidation reaction chamber, and a wet scrubbing tower. The waste gas purification component 6 is connected to the waste heat recovery component 5 through a pipeline, and can perform staged purification treatment on the waste gas after waste heat recovery: first, the dry filter layer intercepts particulate matter in the waste gas; then, the activated carbon adsorption module removes organic pollutants; subsequently, in the photocatalytic oxidation reaction chamber, harmful gases are decomposed by the synergistic effect of ultraviolet light and catalyst; finally, acid-base neutralization and deep washing are performed by the wet scrubbing tower. The other end of the waste gas purification component 6 is equipped with an exhaust chimney with a rain cap and a windproof ring. The chimney is equipped with an online monitoring sensor, which can detect the waste gas emission indicators in real time to ensure that the purified waste gas meets the standards before being discharged.

[0056] The workflow of this utility model for a heating device used in manufacturing flanges is as follows: The operator places the flange to be heated into the preheating chamber 503 for preheating, then removes the flange. The furnace door 102 is opened, and the controller 3 controls the drive motor 702. The slider 703 moves the suspension assembly 4 along the electric track 701 out of the heating chamber 1. The preheated flange is placed at the notch 405 of the placement rod 404 and secured with a silicone gasket. The controller 3 continues to control the drive motor 702, sending the suspension assembly 4 along the electric track 701 into the heating chamber 101. At this time, the furnace door 102 is closed, and the sealing strip in the groove 103 forms a double seal. During heating, the controller 3 controls the heating platform 201, the top heater 202, and the surrounding heating tube assembly 203 of the heating mechanism 2 to work together. The suspension assembly 4 rotates under the drive of the rotary motor 402, and the ultrasonic temperature measurement module 301 monitors the temperature in real time to ensure uniform heating. After heating is complete, the moving assembly 7 removes the suspension assembly 4 and takes out the heated flange; the exhaust gas recovers heat through the waste heat recovery assembly 5 for preheating, and is then treated by the exhaust gas purification assembly 6 before being discharged. Heating continues for the next flange.
