Description

Technical Field

[0001] This invention relates to the field of metal heat treatment equipment technology, specifically to a temperature control device for heat treatment of castings. Background Technology

[0002] Heat treatment of castings is a crucial processing step that improves the internal structure of metal castings, eliminates casting stress, enhances mechanical properties such as hardness, strength, and toughness, and ultimately extends the service life of the castings. Temperature control equipment, as the core equipment of the entire heat treatment production line, is mainly used for real-time monitoring, precise adjustment, and stable control of temperature parameters in heating, holding, and cooling stages, directly determining the consistency of the heat treatment process and the final product quality. Currently, most commonly used temperature control equipment in the industry adopts a movable structure with casters for easy transfer between different workstations in the workshop. The equipment mainly relies on an exposed control console for parameter setting, start / stop control, and operational status monitoring. Due to its ease of operation and flexible layout, it is widely used in the heat treatment production of various metal castings.

[0003] The control consoles of existing casting heat treatment temperature control equipment generally adopt an exposed design, lacking a dedicated automatic protection structure, which has significant drawbacks in actual production. The workshop environment is dusty, and dust easily accumulates on the control panel and buttons. Long-term use affects operational sensitivity and display clarity, and may even lead to button malfunction or short circuits. Although some equipment is equipped with simple covers, they must be opened and closed manually, which is inconvenient and prevents observation of the operating status when closed. Furthermore, cleaning the control console relies heavily on manual wiping, which is inefficient, incomplete, and allows dust to be re-entrained, increasing labor intensity and making it difficult to ensure long-term stable operation of the equipment, thus reducing its service life. Summary of the Invention

The protective component includes a mounting bracket mounted on top of the temperature controller. A dual-axis motor is mounted on the top of the mounting bracket. A reciprocating lead screw is mounted on the output shaft surface of the dual-axis motor. A slide bar is threaded onto the surface of the reciprocating lead screw and slidably connected to the inner side of the mounting bracket. A connecting strip is mounted on the surface of the slide bar and slidably connected to the top of the temperature controller. A protective plate is mounted on the surface of the connecting strip, and a viewing window is mounted on the surface of the protective plate. Preferably, a cleaning brush is rotatably connected to the inner side of the protective plate, a gear is mounted on the surface of the cleaning brush, the gear is rotatably connected to the surface of the protective plate, and a rack is meshed with the bottom of the gear.

Preferably, a drainage frame is installed on the protective plate, a vacuum pump is installed on the top of the drainage frame, a collection box is connected to the top of the vacuum pump through a pipe, and a door is hinged to the surface of the collection box.

[0006] Preferably, the temperature controller has a groove on its top, and the protective plate and connecting strip both have triangular cross-sections. Preferably, the protective components are provided in two sets, and both sets of protective components are symmetrically arranged with the center line of the temperature controller as the axis of symmetry. Preferably, the support assembly includes: a fixing block mounted on the surface of the temperature controller; a connecting plate mounted on the bottom of the protective plate; a rack two mounted on the inner side of the connecting plate; and the rack two mounted inside the fixing block. Preferably, a second gear meshes with the bottom of the second rack, a transmission wheel is mounted on the surface of the second gear, a connecting wheel is connected to the surface of the transmission wheel via a belt, a support frame is mounted on the surface of the connecting wheel, and a support plate is hinged to the inner side of the support frame.

[0007] Preferably, a spiral spring is installed on the surface of the support plate, and the spiral spring is installed on the inner side of the support plate.

[0008] Beneficial effects Compared with the prior art, the present invention provides a temperature control device for heat treatment of castings, which has the following beneficial effects: 1. This casting heat treatment temperature control equipment utilizes a protective assembly. During operation, a dual-axis motor rotates, driving a reciprocating screw to move the slide bar and connecting bar along the slide groove, allowing the protective plate to open smoothly. The protective assembly consists of two symmetrical structures, ensuring synchronous and stable opening and closing with even force distribution. When not in use, it can be closed to cover the control console, effectively preventing dust contamination, foreign object impacts, water stains, and accidental operation. A visual observation window allows for real-time monitoring of the operating status, eliminating the need for frequent opening and significantly extending the control console's lifespan, reducing equipment failure rates, and making temperature control operation safer and more reliable.

[0009] 2. This casting heat treatment temperature control equipment utilizes a protective component design. When the protective plate moves, gear one and rack one mesh, driving the cleaning brush to rotate and wipe the dust against the control panel, ensuring a more thorough and complete cleaning. Simultaneously, a dust pump is activated, transporting dust through a dredging frame and pipes to a collection box for centralized storage, preventing secondary dust re-spread and contamination of the equipment. Dust can be quickly cleaned through the box door, reducing the frequency of manual maintenance, keeping the control panel clean, ensuring stable transmission and accurate detection of temperature control signals, and improving the overall quality of heat treatment.

[0010] 3. This casting heat treatment temperature control equipment utilizes a support assembly. When the protective plate opens, it moves the connecting plate and rack two, driving gear two and the transmission wheel to rotate. The belt then drives the connecting wheel to rotate synchronously, causing the support frame to flip downwards from the groove of the fixed block. Under the action of the spiral spring, the support plate unfolds outwards, forming a stable U-shaped support structure with the support frame and pressing against the ground. This elevates the casters, preventing slippage, displacement, and shaking during operation, resulting in more secure placement, more stable operation, more precise temperature control, and safer operation.

[0013] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0014] Please see Figure 1 - Figure 7 As shown, a casting heat treatment temperature control device includes a temperature controller 1, a control console 2 mounted on the surface of the temperature controller 1, and casters 3 mounted on the bottom of the temperature controller 1. It also includes a protection component 4 for protecting the console 2 when it is not in use; Support component 6 is used to support the temperature controller 1 during use; First, the protective component 4 includes a mounting bracket 41, which is installed on the top of the temperature controller 1. A dual-axis motor 42 is mounted on the top of the mounting bracket 41. A reciprocating lead screw 43 is mounted on the output shaft surface of the dual-axis motor 42. A slide bar 44 is threaded onto the surface of the reciprocating lead screw 43 and is slidably connected to the inner side of the mounting bracket 41. A connecting bar 45 is mounted on the surface of the slide bar 44 and is slidably connected to the top of the temperature controller 1. A protective plate 46 is mounted on the surface of the connecting bar 45 and a viewing window 47 is mounted on the surface of the protective plate 46. The dual-axis motor 42 drives the reciprocating lead screw 43 to move the slide bar 44, the connecting bar 45, and the protective plate 46 synchronously, thereby realizing the automatic opening and closing of the control console 2. With the viewing window 47, the operating status can be viewed in real time when the console is closed, improving ease of use and safety.

[0015] Secondly, a cleaning brush 48 is rotatably connected to the inner side of the protective plate 46. A gear 49 is mounted on the surface of the cleaning brush 48. The gear 49 is rotatably connected to the surface of the protective plate 46. A rack 410 is meshed at the bottom of the gear 49. The rack 410 is mounted on the top of the control console 2. The movement of the protective plate 46 drives the gear 49 and the rack 410 to mesh and transmit power, so that the cleaning brush 48 automatically rotates and wipes the surface of the control console 2, realizing the linkage between opening and closing and cleaning, and completing the dust removal operation without additional power.

[0016] Furthermore, a drainage frame 411 is installed on the protective plate 46, and a dust pump 412 is installed on the top of the drainage frame 411. The top of the dust pump 412 is connected to a collection box 414 through a pipe 413. A box door 415 is hinged to the surface of the collection box 414. The dust pump 412 generates negative pressure, which draws the dust into the drainage frame 411 and transports it to the collection box 414 through the pipe 413 for centralized storage, thus avoiding secondary dust pollution. The box door 415 can be opened for quick cleaning, reducing maintenance difficulty.

[0017] Furthermore, the temperature controller 1 has a slide groove 10 on its top. The cross-section of the protective plate 46 and the connecting strip 45 is triangular. The slide groove 10 guides and limits the connecting strip 45 to ensure that the protective plate 46 moves smoothly without deviation. The triangular cross-section structure has high strength and smooth guidance, which can improve the operational stability and service life of the protective component 4.

[0018] Furthermore, the protective components 4 are provided in two sets, and both sets of protective components 4 are symmetrically arranged with the center line of the temperature controller 1 as the axis of symmetry. The two sets of symmetrical structures realize bidirectional synchronous opening and closing, providing comprehensive protection coverage, uniform force distribution, and smoother movement, which can improve the integrity and reliability of the control console 2 protection.

[0019] Furthermore, the support component 6 includes: a fixing block 61, which is installed on the surface of the temperature controller 1; a connecting plate 62 is installed at the bottom of the protective plate 46; a rack 63 is installed on the inner side of the connecting plate 62; and the rack 63 is installed inside the fixing block 61. The movement of the protective plate 46 drives the connecting plate 62 and the rack 63 to move synchronously, thereby realizing the linkage between the protection and support mechanisms. No separate control is required, simplifying operation and improving the automation level of the equipment.

[0020] Furthermore, a gear 64 meshes with the bottom of rack 2 63, a transmission wheel 65 is mounted on the surface of gear 2 64, a connecting wheel 66 is connected to the surface of transmission wheel 65 via belt drive, a support frame 67 is mounted on the surface of connecting wheel 66, and a support plate 68 is hinged to the inner side of support frame 67. Through rack 2 63 driving gear 2 64, transmission wheel 65 and connecting wheel 66, the support frame 67 and support plate 68 are automatically unfolded, realizing automatic support after movement and improving the stability of equipment use.

[0021] Furthermore, the cross-section of the support plate 68 and the support frame 67 after connection is U-shaped, and the bottom of the fixing block 61 is provided with a groove 610. The U-shaped structure has a large support area and strong stability, which can effectively support the equipment. The groove 610 is used to store the support frame 67 and the support plate 68, which does not occupy space and does not affect the movement of the equipment.

[0022] Finally, a spiral spring 611 is installed on the surface of the support plate 68. The spiral spring 611 is installed on the inner side of the support plate 68. The spiral spring 611 provides elastic torque, so that the support plate 68 automatically unfolds outward to fit the ground, ensuring timely and reliable support. When it is retracted, it can store energy and reset, realizing the free switching between support and storage.

[0023] Working principle: The temperature controller 1 is equipped with casters 3 at the bottom, which can freely push the equipment to the heat treatment station; at this time, the protective component 4 is in the closed state, and the protective plate 46 covers the outside of the control console 2 to prevent dust and bumps from damaging the control console 2.

[0024] When the equipment is put into use, the operator starts the dual-axis motor 42. After the motor is powered on, the output shafts at both ends rotate synchronously, driving the reciprocating lead screws 43 on both sides to rotate at a uniform and stable speed. The reciprocating lead screws 43 use the thread meshing action to drive the matching slide bar 44 to slide linearly along the inner side of the fixed frame 41, preventing the slide bar 44 from shaking, jamming or deviating. When the slide bar 44 moves, it synchronously drives the connecting bar 45 to slide smoothly along the slide groove 10 preset on the top of the temperature controller 1. The slide groove 10 guides, limits and supports the connecting bar 45, so that the protective plate 46 opens slowly to both sides of the equipment in a stable posture, so that the control console 2 is completely exposed, which is convenient for the staff to set parameters, switch modes and monitor operation, and complete the pre-operation preparation. During the movement of the protective plate 46, the gear 49 installed on its inner side continuously meshes with the rack 410 fixed on the top of the control console 2. The gear 49 rotates as the protective plate 46 moves, thereby driving the cleaning brush 48 to rotate synchronously. The cleaning brush 48 fits snugly against the panel, buttons, and crevices of the control console 2, thoroughly sweeping away dust and debris through rolling wiping, achieving fully automatic and thorough cleaning of the control console 2. Simultaneously, the vacuum pump 412 is activated during cleaning, generating stable negative pressure to collect and adsorb the raised dust through the drainage frame 411, then transport it through the tube 413 to the collection box 414 for sealed storage, effectively preventing secondary dust dispersion and pollution of the equipment and environment. For later cleaning, the dust can be quickly emptied by simply opening the box door 415, making maintenance simple and efficient. In the closed protective state, the data and operating status of the control console 2 can be directly observed through the viewing window 47 without repeatedly opening the protective panel 46. The protective component 4 adopts two sets of symmetrical structures, with synchronized opening and closing actions, even force distribution, and stable operation, providing comprehensive protection and cleaning coverage. Through the linkage of these structures, the control console 2 can be effectively prevented from being contaminated by dust, impacted by foreign objects, seeped in by water, and accidentally operated, significantly extending the equipment's service life, reducing the frequency of manual maintenance, ensuring stable temperature control accuracy, and making use safer and more convenient.

[0025] When the protective plate 46 of the protective component 4 opens to both sides, the connecting plate 62 at the bottom of the protective plate 46 moves outward synchronously with the protective plate 46. The connecting plate 62 drives the inner rack 63 to slide smoothly and steadily inside the fixed block 61, realizing complete linkage between the protective action and the support action, without the need for an additional drive source. During the sliding process, the rack 63 forms a stable transmission engagement with the gear 64 meshing below, pushing the gear 64 to rotate at a constant speed around its own axis. At the same time as the gear 64 rotates, it drives the coaxially mounted transmission wheel 65 to rotate synchronously. The transmission wheel 65 smoothly transmits power to the connecting wheel 66 through a belt, so that the connecting wheel 66 and the transmission wheel 65 rotate in the same direction and at the same speed, ensuring stable power transmission without slippage or lag. After the connecting wheel 66 rotates, it drives the support frame 67 fixedly connected to it to flip downward, and the support frame 67 gradually rotates out of the groove 610 at the bottom of the fixed block 61. When the support frame 67 flips downwards, it simultaneously drives the inner hinged support plate 68 downwards. Under the elastic restoring force of the spiral spring 611, the support plate 68 automatically and smoothly opens outwards, quickly adjusting to a support posture perpendicular to the ground, so that the support plate 68 and the support frame 67 combine to form a stable U-shaped support structure. This structure, with a large area pressed against the ground, completely avoids problems such as sliding, displacement, shaking, and tilting of the equipment due to vibration and collision during the heat treatment process. Through the automatic unfolding and support of the support component 6, it can ensure more stable equipment operation, more precise temperature control, safer operation, and more secure placement, greatly improving the reliability and safety of the heat treatment process.

[0026] After use, the dual-axis motor 42 is started to rotate in the reverse direction. The motor output shaft drives the reciprocating screw 43 to rotate in the reverse direction synchronously, driving the slide bar 44 and connecting bar 45 to move inward along the slide groove 10, so that the two sets of protective plates 46 close inward in the middle synchronously, completely covering the control console 2 again, forming a closed protective state. At this time, gear 49 rotates in the reverse direction along rack 410, driving the cleaning brush 48 to wipe the surface of the control console 2 again to remove dust. The dust pump 412 continues to work, sucking the residual dust into the collection box 414, realizing the simultaneous completion of closure and secondary cleaning. When the protective plate 46 closes, the bottom connecting plate 62 drives rack 63 to move inward, driving gear 64, transmission wheel 65 and connecting wheel 66 to rotate in the reverse direction synchronously, so that the support frame 67 flips upward and retracts into the groove 610 of the fixing block 61. The support plate 68 retracts along with the support frame 67, the spiral spring 611 is compressed and stores energy, the U-shaped support structure is lifted off the ground, the equipment returns to a freely movable state, and the entire process of protection, cleaning and support is reset.
