Description

Technical Field

[0001] This invention relates to the technical field of aluminum alloy parts processing, specifically a heat treatment device and method for precision machining of aluminum alloy microwave components. Background Technology

[0002] Microwave devices refer to devices that operate in the microwave band. Their housing materials mainly include aluminum alloys, Kovar alloys, oxygen-free copper, and copper alloys. Larger microwave components generally use aluminum alloys as the housing material. Aluminum alloys not only have high strength but also high toughness, mainly due to their good mechanical and processing properties. They exhibit good plasticity after solution treatment and good strengthening effects after heat treatment. Generally, they maintain high strength and good toughness below 150℃, making them ideal structural materials. Therefore, they are widely used in the manufacture of precision equipment.

[0003] The forming and processing technology of aluminum alloy precision equipment includes multiple steps. One step is to place the aluminum alloy material into a mold and form it into the required shape through cold extrusion. However, cold extrusion produces severe plastic deformation at room temperature, which leads to lattice distortion and a large number of dislocations, resulting in high internal stress. Therefore, after cold extrusion, the formed aluminum alloy needs to be heat-treated to eliminate residual stress and prevent dimensional instability and stress corrosion, thereby improving its strength and hardness.

[0004] Traditional heat treatment equipment typically relies on a single sealing ring for door sealing. This results in a short sealing contact path, making the sealing ring prone to localized collapse, aging, and cracking after repeated opening and closing and high-temperature baking. Therefore, current technology, to ensure sufficient sealing pressure when the door is closed, allows the sealing ring to protrude significantly beyond the door flange plane in its free state, reserving enough compression compensation. Even if some aging and collapse occur later, it still guarantees effective sealing pressure when the door is closed. However, when the door is open, the entire protruding sealing ring is completely exposed inside the door, directly encroaching on part of the operating space towards the furnace cavity. Aluminum alloy microwave components are often thin-walled, irregularly shaped structures with precision positioning surfaces and cavities. During loading and unloading, the edges and corners are highly susceptible to collisions with the protruding sealing ring, causing scratches on the positioning surfaces and thin-walled cavities, directly leading to workpiece scrap. Summary of the Invention

[0005] The purpose of this invention is to provide a heat treatment device for the precision machining of aluminum alloy microwave components, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A heat treatment device for precision machining of aluminum alloy microwave components includes a heating treatment device and a quenching treatment device. The heating treatment device includes a box body, and a cover door that can slide along a preset trajectory is installed on the side of the box body. The box body and the cover door cooperate to form a closed heating chamber for accommodating the workpiece to be processed.

[0008] The inner end of the cover door has an embedded groove. A first baffle and a second baffle are symmetrically arranged in the embedded groove, and the outer contours of the first baffle and the second baffle can be inserted into the slot opened in the box body. The second baffle is rotatably connected to the embedded groove.

[0009] The transmission components are symmetrically arranged on the cover door. When the cover door slides outward relative to the box body to receive the workpiece, the transmission components can squeeze the push component installed on the cover door, causing the second baffle to completely disengage from the slot and then fold inward into the inner groove.

[0010] The heat treatment equipment for precision machining of aluminum alloy microwave components as described above: at least two sets of limiting plates are symmetrically arranged on the inward end of the cover, and a guide groove is formed in the limiting plate. Guide posts are respectively opened on the top and bottom ends of the box, and the guide posts can be inserted into the guide groove and slide with the guide groove.

[0011] The heat treatment equipment for precision machining of aluminum alloy microwave components as described above: the transmission component includes a transmission shaft, which is rotatably mounted on the cover door. A limit groove is formed on the transmission shaft. When the transmission shaft moves relative to the housing, the extrusion member disposed in the housing extrudes the transmission shaft to cause it to rotate.

[0012] The heat treatment equipment for precision machining of aluminum alloy microwave components as described above: the extruded part includes a sleeve, the sleeve is slidably sleeved on the drive shaft and arranged along the axial direction of the drive shaft, the sleeve is installed on the housing, and a first ball is movably arranged on the inner wall of the sleeve, which can be inserted into the limiting groove and slidably adapted to the limiting groove.

[0013] The heat treatment equipment for precision machining of aluminum alloy microwave components as described above: the pushing component includes a cam, the cam is rotatably mounted on the cover door, the cam's rotating shaft is connected to the transmission shaft through a first bevel gear set, and a protruding post is provided at the eccentric position of the cam;

[0014] It also includes a movable plate, which is slidably connected to the limiting plate. A groove is formed on the movable plate, and the protrusion can be inserted into the groove and slidably adapted to the groove. Push rods are symmetrically arranged on the side end of the movable plate.

[0015] The heat treatment equipment for precision machining of aluminum alloy microwave components as described above: the first baffle is symmetrically provided with connecting shafts at both ends, the connecting shafts are formed with movable grooves, the connecting shafts are rotatably connected to the first baffle, and the connecting shafts are connected to the rotating shaft of the second baffle through a second bevel gear set.

[0016] The heat treatment equipment for precision machining of aluminum alloy microwave components as described above: when the moving plate reciprocates, the push rod presses against the intermittent control component set on the connecting shaft.

[0017] The heat treatment equipment for precision machining of aluminum alloy microwave components as described above: the intermittent control component includes a sleeve, which is arranged axially along the connecting shaft and slidably connected to the first baffle. A second ball bearing that is movably adapted to the movable groove is movably arranged on the inner wall of the sleeve. A cylindrical cavity is formed on the sleeve, and a clearance component is arranged in the cylindrical cavity.

[0018] It also includes a first spring, which is sleeved on the connecting shaft, with one end of the first spring abutting against the sleeve and the other end abutting against the first baffle.

[0019] The heat treatment equipment for precision machining of aluminum alloy microwave components as described above: the clearance component includes a plug rod, the plug rod is slidably inserted into the cylindrical cavity, and an extrusion block is provided on one end of the plug rod extending out of the cylindrical cavity. An inclined extrusion surface and a horizontal surface are formed on the extrusion block. When the extrusion block moves to abut against the pressure plate installed on the first baffle, the extrusion block can make way for the movement of the push rod. The pressure plate and the push rod are misaligned in the vertical direction.

[0020] It also includes a second spring, which is disposed inside the cylindrical cavity and sleeved on the plug rod. One end of the second spring abuts against the inner wall of the cylindrical cavity, and the other end abuts against the plug rod.

[0021] A heat treatment method for precision machining of aluminum alloy microwave components, using the heat treatment equipment for precision machining of aluminum alloy microwave components as described in any one of the above claims, includes the following steps:

[0022] Step 1: Before the workpiece is heat-treated, the cover door is pulled out of the box. During the movement of the cover door relative to the box, after the second baffle is completely pulled out of the slot, the transmission component is driven by the pressing component to transmit power to the pushing component, so that the pushing component performs a single reciprocating linear motion.

[0023] Step 2: During the process of the cover door moving to the end of the stroke, the reciprocating motion of the pushing component acts on the intermittent control component, which allows the connecting shaft to rotate at a certain angle, driving the second baffle to fold completely inward relative to the groove wall of the inner groove, and the whole thing is stored inside the inner groove of the cover door, effectively avoiding spatial interference between the second baffle and the loading path of the aluminum alloy microwave component to be processed when the second baffle is in the outward state.

[0024] Compared with the prior art, the beneficial effects of the present invention are:

[0025] Under normal closed working conditions, the first and second baffles can be simultaneously embedded into the corresponding slots of the box to form a double-layer sealing barrier, which greatly extends the overflow path of high-temperature gas in the sealed heating chamber, blocks the heat leakage channel of the gap between the cover and the box from the structural level, effectively locks the high-temperature environment inside the chamber, reduces heat loss in the heat treatment process, provides a stable and uniform heat treatment temperature field for aluminum alloy microwave components, and ensures the consistency of precision workpiece processing.

[0026] When the door is open and under load, the transmission component linked to the sliding stroke of the door directly converts the linear motion of the door sliding outward into the axial thrust of the pushing component. Without the need for an additional independent drive source, the second baffle can be automatically driven to rotate and fold inward, completely retracting into the inner groove of the door. This frees up the operating space inside the door and effectively avoids spatial interference between the second baffle in its extended state and the loading path of high-precision workpieces such as aluminum alloy microwave components. It is suitable for bump-free picking and placing in manual operation scenarios and can also perfectly match the precise loading and unloading actions of automated robotic arms, greatly improving the loading and unloading efficiency and operational safety of precision workpieces.

[0038] Various exemplary embodiments, features, and aspects of this application will now be described in detail with reference to the accompanying drawings. The same reference numerals in the drawings denote elements that have the same or similar functions. Although various aspects of the embodiments are shown in the drawings, they are not necessarily drawn to scale unless specifically indicated otherwise.

[0039] The term “exemplary” as used herein means “serving as an example, embodiment, or illustration.” Any embodiment illustrated herein as “exemplary” is not necessarily to be construed as superior to or better than other embodiments.

[0040] Furthermore, to better illustrate this application, numerous specific details are provided in the following detailed embodiments. Those skilled in the art should understand that this application can be implemented even without certain specific details. In some instances, methods, means, and elements well-known to those skilled in the art have not been described in detail in order to highlight the main points of this application.

[0041] Please see Figures 1-10In this embodiment of the invention, a heat treatment device for precision machining of aluminum alloy microwave components includes a heating treatment device and a quenching treatment device. The heating treatment device includes a housing 1, and a cover 2 that can slide along a preset trajectory is fitted to the side end of the housing 1. The housing 1 and the cover 2 cooperate to form a sealed heating chamber for accommodating the workpiece to be processed.

[0042] The cover 2 has an inwardly facing groove. A first baffle 4 and a second baffle 5 are symmetrically arranged in the inward groove, and the outer contours of the first baffle 4 and the second baffle 5 can be inserted into the slot opened in the box 1. The second baffle 5 is rotatably connected to the inward groove.

[0043] The transmission components are symmetrically arranged on the cover door 2. When the cover door 2 slides outward relative to the box body 1 to receive the workpiece, the transmission components can squeeze the push component installed on the cover door 2, causing the second baffle 5 to completely disengage from the slot and then fold inward into the inner groove.

[0044] In one embodiment, the cover 2 is equipped with a tray 3 for receiving the workpiece to be processed.

[0045] Under normal closed operation, the outer contours of the first baffle 4 and the second baffle 5 are simultaneously inserted into the corresponding slots of the housing 1 to form a double-layer sealing barrier, completely isolating the sealed heating chamber from the external space. At this time, the double-layer baffle and the slots of the housing 1 extend the overflow path of the gas in the chamber, which can effectively lock in the high temperature heat in the chamber and prevent heat from leaking out in large quantities from the connection gap between the cover 2 and the housing 1.

[0046] When the door is open and under load, as the cover 2 slides outward relative to the housing 1, the sliding stroke of the cover 2 will drive the symmetrically arranged transmission components on it to move synchronously. During the movement, the transmission components will come into contact with the pressing parts pre-installed on the cover 2, thereby converting the linear sliding power of the cover 2 into an axial thrust on the pushing components. This thrust first acts on the second baffle 5, causing the second baffle 5, which was originally in the contact state, to rotate at a certain angle, so that it first completely disengages from the slot of the housing 1, and then continues to flip inward, finally folding and storing completely inside the inner groove of the cover 2. This frees up the operating space inside the cover 2, effectively avoiding spatial interference between the second baffle 5 and the loading path of the aluminum alloy microwave components to be processed when the second baffle 5 is in the outward state. This makes it convenient for operators or automated robots to place the aluminum alloy microwave components smoothly onto the loading station of the cover 2, effectively avoiding the risk of bumps during manual operation and greatly improving the loading and unloading efficiency of precision workpieces such as aluminum alloy microwave components.

[0047] As a further embodiment of the present invention, at least two sets of limiting plates 6 are symmetrically arranged at the inward end of the cover 2, and a guide groove is formed in the limiting plate 6. Guide posts are respectively provided on the top and bottom ends of the box body 1, and the guide posts can be inserted into the guide groove and slide with the guide groove.

[0048] When the cover 2 completes the opening and closing action along the preset trajectory, the guide posts that are pre-fixed at the top and bottom of the box 1 will be embedded in the guide groove formed by the symmetrically arranged limiting plates 6 on the inner side of the cover throughout the entire process, and the two always maintain a high-precision sliding fit.

[0049] As a further embodiment of the present invention, please refer to... Figure 6 and Figure 10 The transmission assembly includes a transmission shaft 7, which is rotatably mounted on the cover 2. A limiting groove 701 is formed on the transmission shaft 7. When the transmission shaft 7 moves relative to the housing 1, the pressing member disposed in the housing 1 presses the transmission shaft 7 to cause it to rotate.

[0050] The extrusion component includes a sleeve 8, which is slidably sleeved on the transmission shaft 7 and arranged along the axial direction of the transmission shaft 7. The sleeve 8 is mounted on the housing 1, and a first ball bearing is movably arranged on the inner wall of the sleeve 8, which can be inserted into the limiting groove 701 and is slidably adapted to the limiting groove 701.

[0051] It should be noted that the limiting groove 701 includes a first straight groove, a threaded groove and a second straight groove. Under normal closing conditions, the first ball is located in the first straight groove and away from the end of the threaded groove.

[0052] When the cover door 2 slides outward into the bearing position, the drive shaft 7 moves outward synchronously with the cover door 2. At this time, the first ball bearing on the inner wall of the sleeve 8 moves relative to each other in the first straight groove. When the first baffle 4 and the second baffle 5 are completely pulled out of the groove, the first ball bearing moves into the threaded groove. At this time, the drive shaft 7 continues to move, and the first ball bearing generates an inclined squeezing force on the threaded groove. Through the inclined plane guide, the drive shaft 7 rotates around its own axis at a certain angle, driving the second baffle 5 to gradually flip inward from the abutment sealing position, and finally completely fold and store it inside the inner groove 201 of the cover door 2. The automatic storage action of the second baffle 5 can be completed entirely by the linear sliding power of the cover door 2, without the need for additional independent drive components.

[0053] During the full stroke of the drive shaft 7, the first ball always maintains a sliding fit with the limiting groove 701, which will not cause any jamming or sticking, and can also precisely control the rotation angle of the drive shaft 7, ensuring that the flipping stroke of the second baffle 5 is completely matched with the storage space of the inner groove 201, and there will be no collision or interference between the second baffle 5 and the inner wall of the inner groove 201.

[0054] As a further embodiment of the present invention, please refer to... Figure 10 The pushing component includes a cam 10, which is rotatably mounted on the cover 2. The rotating shaft of the cam 10 is connected to the transmission shaft 7 via a first bevel gear set 9. A protrusion 1001 is provided at the eccentric position of the cam 10.

[0055] It also includes a movable plate 11, which is slidably connected to the limiting plate 6. A groove 1101 is formed on the movable plate 11. The protruding post 1001 can be inserted into the groove 1101 and slidably adapted to the groove 1101. Push rods 1102 are symmetrically arranged on the side end of the movable plate 11.

[0056] When the aforementioned drive shaft 7 rotates at a fixed angle, the power is transmitted through the first bevel gear set 9, which synchronously converts the circumferential rotation of the drive shaft 7 into the fixed-axis rotation of the cam 10. During the rotation of the cam 10 around its own axis, the convex post 1001 set at its eccentric position will slide relative to the slide groove 1101 on the moving plate 11. The rotational motion of the cam 10 is converted into the linear reciprocating movement of the moving plate 11 along the guide direction of the limiting plate 6 by the contour guide of the slide groove 1101.

[0057] As a further embodiment of the present invention, please refer to... Figures 6-9 The first baffle 4 has connecting shafts 12 symmetrically arranged at both ends. The connecting shafts 12 have movable grooves 1201 formed on them. The connecting shafts 12 are rotatably connected to the first baffle 4. The connecting shafts 12 are connected to the rotating shaft of the second baffle 5 through the second bevel gear set 13.

[0058] When the moving plate 11 reciprocates, the push rod 1102 presses against the intermittent control component disposed on the connecting shaft 12.

[0059] The intermittent control component includes a sleeve 16, which is arranged along the axial direction of the connecting shaft 12 and slidably connected to the first baffle 4. A second ball is movably arranged on the inner wall of the sleeve 16 and is slidably adapted to the movable groove 1201. A cylindrical cavity 1601 is formed on the sleeve 16, and a clearance component is provided in the cylindrical cavity 1601.

[0060] It also includes a first spring 15, which is sleeved on the connecting shaft 12. One end of the first spring 15 abuts against the sleeve 16, and the other end abuts against the first baffle 4.

[0061] The clearance component includes a plug rod 17, which is slidably inserted into the cylindrical cavity 1601. A pressing block 18 is provided on one end of the plug rod 17 that extends out of the cylindrical cavity 1601. An inclined pressing surface and a horizontal surface are formed on the pressing block 18. When the pressing block 18 moves to abut against the pressure plate 14 installed on the first baffle 4, the pressing block 18 can make way for the movement of the push rod 1102. The pressure plate 14 and the push rod 1102 are misaligned in the vertical direction.

[0062] It also includes a second spring 19, which is disposed inside the cylindrical cavity 1601 and sleeved on the plug rod 17. One end of the second spring 19 abuts against the inner wall of the cylindrical cavity 1601, and the other end abuts against the plug rod 17.

[0063] It should be noted that the movable groove 1201 is divided into straight groove and threaded groove.

[0064] When the cover door 2 slides outward into the door opening and bearing position, the moving plate 11 drives the push rod 1102 to move towards the connecting shaft 12. The push rod 1102 first contacts the horizontal surface of the extrusion block 18, thereby causing the extrusion sleeve 16 to move linearly along the axis of the connecting shaft 12. At this time, the second ball moves in the threaded groove and drives the connecting shaft 12 to rotate around its own axis at a certain angle through the inclined guide. This enables the second baffle 5 to rotate relative to the first baffle 4, driving the second baffle 5 to gradually flip inward from the abutment sealing position, and finally completely fold and store it inside the inner groove of the cover door 2.

[0065] When the second ball moves to the intersection of the threaded groove and the straight groove, the axial movement of the sleeve 16 just completes the 90° flipping action of the second baffle 5. At this time, the second baffle 5 has completely disengaged from the groove of the housing 1. The first spring 15 is synchronously compressed to the preset compression amount by the sleeve 16. Then, the inclined surface of the extrusion block 18 contacts the pressure plate 14 fixed on the first baffle 4. The push rod 1102 continues to maintain the feeding action. Under the rigid limiting guide of the pressure plate 14, the inclined surface of the extrusion block 18 is forced to generate a radial component force, which pushes the insertion rod 17 to retract inward along the cylindrical cavity 1601 of the sleeve 16, and synchronously compresses the second spring 19 to store elastic potential energy. The extrusion block 18 is completely retracted into the cylindrical cavity 1601, making room for the push rod 1102 to move.

[0066] After the push rod 1102 successfully passes over the fully retracted compression block 18, the second ball slides completely from the threaded groove into the straight groove. The first spring 15, which was originally in a compressed state, instantly releases its stored elastic potential energy, pushing the sleeve 16 to quickly reverse and reset along the connecting shaft 12. During the reset process, the second ball slides axially relative to the connecting shaft 12 in the straight groove without helical guidance constraint, and will not cause the connecting shaft 12 to generate additional rotational motion, thus avoiding the second baffle 5 from rotating erroneously. When the sleeve 16 returns to the initial origin position, the second ball slides out from the end of the straight groove and re-engages in the starting position of the threaded groove, completing the reset of the entire action cycle. At this time, the reset action of the sleeve 16 is completed before the retraction action of the moving plate 11, returning to the initial trigger position in advance, and can enter the standby state for the next door opening action without waiting for the moving plate 11 to retract completely.

[0067] Throughout the entire action cycle, the pressure plate 14 and the push rod 1102 remain vertically misaligned and will not interfere rigidly. The stroke design of the clearance component can precisely control the rotation angle of the connecting shaft 12, ensuring that the second baffle 5 can be folded and stored inside the recessed groove of the cover door 2.

[0068] A heat treatment method for precision machining of aluminum alloy microwave components, using the heat treatment equipment for precision machining of aluminum alloy microwave components as described in any one of the above claims, includes the following steps:

[0069] Step 1: Before the workpiece to be processed undergoes heat treatment, the control cover 2 is pulled out from the box 1. During the movement of the cover 2 relative to the box 1, after the second baffle 5 is completely pulled out from the slot, the transmission component is driven by the pressing component to perform power transmission to the pushing component, so that the pushing component performs a single reciprocating linear motion.

[0070] Step 2: During the process of the cover door 2 moving to the end of the stroke, the reciprocating motion of the pushing component acts on the intermittent control component, so that the connecting shaft 12 can rotate at a certain angle, driving the second baffle 5 to fold completely inward relative to the wall of the inner groove, and the whole is stored in the inner groove inside the cover door 2, effectively avoiding spatial interference between the second baffle 5 and the loading path of the aluminum alloy microwave component to be processed when the second baffle 5 is in the outward state.

[0071] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0072] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.

One end of the first spring (15) abuts against the sleeve (16), and the other end abuts against the first baffle (4).

9. The heat treatment equipment for precision machining of aluminum alloy microwave components according to claim 8, characterized in that, The clearance component includes a plug rod (17), which is slidably inserted into the cylindrical cavity (1601). A pressing block (18) is provided on one end of the plug rod (17) that extends out of the cylindrical cavity (1601). An inclined pressing surface and a horizontal surface are formed on the pressing block (18). When the pressing block (18) moves to abut against the pressure plate (14) installed on the first baffle (4), the pressing block (18) can make way for the movement of the push rod (1102). The pressure plate (14) and the push rod (1102) are misaligned in the vertical direction. It also includes a second spring (19), which is disposed in the cylindrical cavity (1601). The second spring (19) is sleeved on the plug rod (17). One end of the second spring (19) abuts against the inner wall of the cylindrical cavity (1601), and the other end abuts against the plug rod (17).

10. A heat treatment method for precision machining of aluminum alloy microwave components, characterized in that, The heat treatment equipment for precision machining of aluminum alloy microwave components as described in any one of claims 1-9 includes the following steps: Step 1: Before the workpiece to be processed is heat treated, the cover door (2) is pulled out from the box (1). During the movement of the cover door (2) relative to the box (1), after the second baffle (5) is completely pulled out from the slot, the transmission component is driven by the pressing component to perform power transmission to the pushing component, so that the pushing component performs a single reciprocating linear motion. Step 2: During the process of the cover (2) moving to the end of the stroke, the reciprocating motion of the push component acts on the intermittent control component, so that the connecting shaft (12) can rotate at a certain angle, driving the second baffle (5) to fold completely inward relative to the groove wall of the inner groove, and the whole is stored in the inner groove inside the cover (2), effectively avoiding spatial interference between the second baffle (5) and the loading path of the aluminum alloy microwave component to be processed when the second baffle (5) is in the outward state.
