Description
Technical Field
[0001] This utility model relates to the field of high-precision casting processing technology for wax molds, specifically a heat treatment device for high-precision casting processing of wax molds. Background Technology
[0002] High-precision wax mold castings are widely used in high-end industries such as aerospace, automobile manufacturing, and medical devices due to their excellent dimensional accuracy and surface quality. After forming, these castings usually need to undergo aging treatment in a heat treatment device to eliminate internal stress, stabilize the metallographic structure, and thus improve the hardness, strength, and dimensional stability of the castings. Among them, the aging furnace is the core equipment for realizing this process, and its performance directly affects the final quality of the castings. The working principle of the aging furnace is to heat the castings at a specific temperature, so as to promote the precipitation, diffusion, and other microscopic changes of alloying elements inside the castings, thereby achieving the purpose of strengthening the material properties. In this process, the placement method of the castings, the uniformity of heating, and the stability during the treatment process are crucial.
[0003] However, in existing aging furnace applications, the workpiece placement structure is relatively simple, often using fixed trays or shelves. Workpieces tend to stick close to the furnace bottom or wall, resulting in uneven heating. At the same time, workpieces cannot move at a uniform speed during processing, and there are often dead zones in the furnace, causing insufficient heating of workpieces in these areas, further exacerbating the heating differences. In addition, for some irregularly shaped workpieces and those with unstable centers of gravity, which are difficult to place stably, the lack of effective stabilization measures makes them prone to significant displacement or even slippage during processing. This not only affects the processing effect itself but may also collide with and damage other workpieces, reducing product quality and production efficiency. Utility Model Content
[0004] To address the problems mentioned in the background art, the purpose of this utility model is to provide a heat treatment device for high-precision casting processing of wax molds. This device features centered, suspended workpiece placement, uniform rotation for even heating, and stable positioning to prevent displacement and slippage. It improves upon or solves the problems in existing aging furnace applications where workpiece placement structures are relatively simple, often using fixed trays or shelves, leading to workpieces easily sticking to the furnace bottom or wall, resulting in uneven heating. Furthermore, workpieces cannot move at a uniform speed during processing, and dead zones of heat flow easily exist within the furnace, causing insufficient heating in these areas and further exacerbating heating differences. In addition, for some irregularly shaped workpieces or those with unstable centers of gravity, the lack of effective stabilization measures makes them prone to significant displacement or even slippage during processing, affecting not only their own processing results but also potentially colliding with and damaging other workpieces, reducing product quality and production efficiency.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a heat treatment device for high-precision casting processing of wax molds, comprising a furnace box and a furnace box door, wherein the furnace box door is located on the front side of the furnace box and the furnace box is rotatably connected, and a rotating placement device is provided inside the furnace box.
[0006] The rotating placement device includes a rotating rod, a motor, placement components, and stabilizing mechanisms. The rotating rod is located inside the furnace and is rotatably connected to the furnace at both its upper and lower ends, with the upper end extending out of the furnace. The motor is fixedly connected to the upper end of the rotating rod and to the upper surface of the furnace. There are three placement components, which are evenly fitted onto the surface of the rotating rod. There are three stabilizing mechanisms, which are respectively located on the upper ends of the three placement components.
[0007] In a preferred embodiment of this utility model, the placement component includes a placement plate, through holes, and movable limiting grooves. The placement plate is sleeved on the surface of the rotating rod and fixedly connected to the rotating rod. There are several through holes, which are evenly distributed on the surface of the placement plate. There are six movable limiting grooves, which are evenly distributed on the front and rear sides of the upper surface of the placement plate, with three on each side, and all of them penetrate the placement plate.
[0008] As a preferred embodiment of the present invention, the stabilizing mechanism includes a central clamping component and a linkage control component. The number of central clamping components is two, and they are respectively arranged on the front and rear sides of the placement plate. The linkage control component is arranged on the lower side of the placement plate.
[0009] In a preferred embodiment of this utility model, the central clamping assembly includes a carrier plate, T-shaped sliders, and clamping plates. The carrier plate is disposed on the front side of the upper surface of the placement plate and is movably connected to the placement plate. There are three T-shaped sliders, all of which are fixedly connected to the lower surface of the carrier plate. The lower ends of the three T-shaped sliders extend through the interior of the three movable limiting grooves at the front end to the lower end of the placement plate and are slidably connected to the movable limiting grooves. There are several clamping plates, which are uniformly fixedly connected to the upper surface of the carrier plate.
[0010] As a preferred embodiment of this utility model, anti-slip textures are provided on the surfaces of the clamping plates on the front and rear sides that are close to each other.
[0011] In a preferred embodiment of this invention, the linkage control component includes a self-locking screw, bearing seats, moving blocks, and a knob. The self-locking screw is positioned below the placement plate and corresponds to the moving limit groove located in the middle. There are three bearing seats, which are respectively fitted onto the front and rear ends and the middle end surface of the self-locking screw and are rotatably connected to the self-locking screw. The upper ends of the three bearing seats are fixedly connected to the lower surface of the placement plate. There are two moving blocks, which are fitted onto the front and rear ends of the self-locking screw and are threadedly connected to the self-locking screw. The upper ends of the two moving blocks are fixedly connected to the lower surfaces of the two middle T-shaped sliders, and the threads of the two moving blocks have opposite directions. The knob is fixedly connected to the front end of the self-locking screw.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0013] 1. This utility model, through the combined use of a furnace box, furnace door, rotating placement device, rotating rod, motor, placement component, placement plate, through hole, moving limit groove, stabilizing mechanism, centering clamping component, carrier plate, T-shaped slider, clamping plate, linkage control component, self-locking screw, bearing seat, moving block, knob, and anti-slip texture, improves or solves to a certain extent the problems in existing aging furnace applications where the workpiece placement structure is relatively simple, often using fixed trays or shelves, and the workpiece easily sticks to the furnace bottom or wall, resulting in uneven heating. At the same time, the workpiece cannot move at a uniform speed during processing, and there are often dead zones in the furnace, causing insufficient heating of the workpiece in that area, further aggravating the heating difference. In addition, for some irregularly shaped workpieces and those with unstable placement centers, which are difficult to place stably, due to the lack of effective stabilizing measures, they are prone to large displacement or even slippage during processing, which not only affects their own processing effect but may also collide and damage other workpieces, reducing product quality and production efficiency.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention.

[0024] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not adhering to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, actual manufacturing should include the three-dimensional spatial dimensions of length, width, and depth.
[0025] Example 1
[0026] Reference Figure 1-4 This is the first embodiment of the present invention, which provides a heat treatment device for high-precision casting of wax molds, including a furnace box 1 and a door box 2. The door box 2 is located on the front side of the furnace box 1 and the furnace box 1 is rotatably connected. A rotating placement device 3 is provided inside the furnace box 1.
[0027] The rotating placement device 3 includes a rotating rod 4, a motor 5, placement components 6, and a stabilizing mechanism 7. The rotating rod 4 is located inside the furnace 1, and both its upper and lower ends are rotatably connected to the furnace 1, with the upper end extending out of the furnace 1. The motor 5 is fixedly connected to the upper end of the rotating rod 4 and to the upper surface of the furnace 1. There are three placement components 6, which are evenly fitted onto the surface of the rotating rod 4. There are three stabilizing mechanisms 7, which are respectively located on the upper ends of the three placement components 6.
[0028] Specifically, this aging furnace enables the workpiece to be placed in the center and suspended in the air, rotated at a uniform speed to be heated evenly, and provides stable positioning for the workpiece, effectively improving the heat treatment quality and stability of high-precision castings made from wax molds.
[0029] Furthermore, by setting the motor 5 to drive the rotating rod 4 to rotate the placement part 6 and the workpiece, the stabilizing mechanism 7 clamps the workpiece in the center. Through the synergistic effect of the rotating placement device 3 and the stabilizing mechanism 7, the workpiece is heated evenly and placed stably.
[0030] Example 2
[0031] In the second embodiment of this utility model, the placement component 6 includes a placement plate 61, through holes 62, and movable limiting grooves 63. The placement plate 61 is sleeved on the surface of the rotating rod 4 and fixedly connected to the rotating rod 4. There are several through holes 62, which are evenly opened on the surface of the placement plate 61. There are six movable limiting grooves 63, which are evenly opened on the front and rear sides of the upper surface of the placement plate 61, with three on each side, and all of them penetrate the placement plate 61.
[0032] Specifically, by setting up the placement component 6, the suspended placement plate 61 prevents the workpiece from touching the bottom, and the through hole 62 enhances the circulation of hot air, and the rotation achieves uniform heating of the workpiece, thus improving the overall heat balance of the workpiece.
[0033] Furthermore, the motor 5 is started, which drives the rotating rod 4 to rotate. The rotating rod 4 then drives the three placement pieces 6 and the workpiece placed on them to rotate at a constant speed. During this process, the placement plate 61 is suspended in the air by the rotating rod 4 to prevent the workpiece from touching the bottom of the furnace 1. Combined with the uniform rotation of the workpiece, it can effectively reduce the dead zone of heat flow and make all parts of the workpiece evenly heated. The several through holes 62 opened on the surface of the placement plate 61 can promote the circulation of hot air in the furnace and make the heat penetrate more evenly to all parts of the workpiece.
[0034] Example 3
[0035] In the third embodiment of this utility model, the stabilizing mechanism 7 includes a central clamping component 71 and a linkage control component 72. There are two central clamping components 71, which are respectively arranged on the front and rear sides of the placement plate 61, and the linkage control component 72 is arranged on the lower side of the placement plate 61.
[0036] The centering clamping assembly 71 includes a carrier plate 711, T-shaped sliders 712 and clamping plates 713. The carrier plate 711 is disposed on the front side of the upper surface of the placement plate 61 and is movably connected to the placement plate 61. There are three T-shaped sliders 712, all of which are fixedly connected to the lower surface of the carrier plate 711. The lower ends of the three T-shaped sliders 712 extend to the lower end of the placement plate 61 through the interior of the three front-end movable limiting grooves 63 and are slidably connected to the movable limiting grooves 63. There are several clamping plates 713, which are evenly fixedly connected to the upper surface of the carrier plate 711.
[0037] Anti-slip texture 8 is provided on the surface of the front and rear clamping plates 713 that are close to each other;
[0038] The linkage control component 72 includes a self-locking screw 721, bearing seats 722, moving blocks 723, and a knob 724. The self-locking screw 721 is located below the placement plate 61 and corresponds to the position of the moving limit groove 63 located in the middle. There are three bearing seats 722, which are respectively sleeved on the front and rear ends and the middle end surface of the self-locking screw 721 and are rotatably connected to the self-locking screw 721. The upper ends of the three bearing seats 722 are fixedly connected to the lower surface of the placement plate 61. There are two moving blocks 723, which are sleeved on the front and rear ends surface of the self-locking screw 721 and are threadedly connected to the self-locking screw 721. The upper ends of the two moving blocks 723 are fixedly connected to the lower surfaces of the two T-shaped sliders 712 located in the middle. The threads of the two moving blocks 723 are in opposite directions. The knob 724 is fixedly connected to the front end of the self-locking screw 721.
[0039] Specifically, by setting up a stabilizing mechanism 7, in which the centering clamping component 71 and the linkage control component 72 work together to achieve centering clamping of the workpiece, the anti-slip texture 8 design enhances clamping stability and effectively prevents the workpiece from shifting or slipping during rotation.
[0040] Furthermore, the workpiece is placed on the upper surface of the placement plate 61 and positioned between the front and rear centered clamping components 71. Then, the knob 724 is rotated to drive the self-locking screw 721 to rotate. Since the moving block 723 is threadedly connected to the self-locking screw 721 and the upper end of the moving block 723 is fixed to the T-shaped slider 712, and the T-shaped slider 712 slides along the moving limit groove 63, the rotation of the self-locking screw 721 will drive the two moving blocks 723 to move synchronously towards the center, thereby driving the carrier plates 711 and clamping plates 713 on both sides to move towards each other, achieving stable centered clamping of the workpiece. At the same time, the centered clamping component 71 enhances the friction with the workpiece through the anti-slip texture 8, stably restricting the position of the workpiece and preventing it from shifting or slipping during rotation, ensuring a stable and efficient aging process.
[0041] Working principle:
[0042] In use, the workpiece is placed on the upper surface of the placement plate 61, positioned between the front and rear centered clamping components 71. Then, the knob 724 is turned, causing the self-locking screw 721 to rotate. Since the moving block 723 is threadedly connected to the self-locking screw 721, and the upper end of the moving block 723 is fixed to the T-shaped slider 712, while the T-shaped slider 712 slides along the moving limit groove 63, the rotation of the self-locking screw 721 drives the two moving blocks 723 to move synchronously towards the center. This, in turn, causes the carrier plates 711 and clamping plates 713 on both sides to move towards each other, achieving stable centered clamping of the workpiece. After clamping is completed, the motor 5 is started, and the motor 5 drives the rotating... When rod 4 rotates, it drives the three placement pieces 6 and the workpiece placed on them to rotate at a constant speed. During this process, the placement plate 61 is suspended in the air by the rotating rod 4 to prevent the workpiece from sticking close to the bottom of the furnace 1. With the uniform rotation of the workpiece, the dead zone of heat flow can be effectively reduced, so that all parts of the workpiece are heated evenly. Several through holes 62 on the surface of the placement plate 61 can promote the circulation of hot air in the furnace, so that the heat can penetrate to all parts of the workpiece more evenly. At the same time, the central clamping component 71 enhances the friction with the workpiece through the anti-slip texture 8, firmly restricts the position of the workpiece, and prevents it from shifting or slipping during rotation, so as to ensure the stability and efficiency of the aging process.
[0043] In summary, by using the combined components of furnace 1, furnace door 2, rotating placement device 3, rotating rod 4, motor 5, placement component 6, placement plate 61, through hole 62, moving limit groove 63, stabilizing mechanism 7, centering clamping component 71, carrier plate 711, T-shaped slider 712, clamping plate 713, linkage control component 72, self-locking screw 721, bearing seat 722, moving block 723, knob 724, and anti-slip texture 8, the workpiece is placed in the center and suspended, rotates at a uniform speed for even heating, and is stably limited to prevent displacement and slippage.
