Description

Technical Field

[0001] Embodiments of the present disclosure relate to the technical field of heat treatment devices, and more particularly, to a heat treatment device for metal workpieces. Background Art

[0002] The expansion section of a rocket engine in the prior art is a cylindrical structure, and the cross-sectional diameter of the expansion section of the rocket engine increases sequentially from top to bottom. In order not to deform during the solution and aging heat treatment process, a support member needs to be added inside the expansion section. The support member is also a cylindrical structure, and the cross-sectional diameter increases sequentially from top to bottom. In order to reduce the weight of the support member, the support member is designed as a hollow structure, and a number of weight-reducing holes are designed on the support structure body. A thickening layer is designed below the support member, and the thickening layer forms a clamping surface. The bottom end surface of the rocket engine expansion section can be clamped on the clamping surface, and the clamping surface is located in the middle position of the weight-reducing holes. Therefore, when the rocket engine expansion section is sleeved outside the support member, a jacking hole is formed between the bottom end surface of the rocket engine expansion section and the bottom wall of the weight-reducing hole. Since the bottom end surface of the expansion section is lapped on the middle position of the weight-reducing hole by the clamping surface, a hydraulic clamp is placed in the jacking hole, and after the hydraulic clamp expands, the rocket engine expansion section is jacked up so that there is no longer adhesion between the expanded section of the rocket engine after heat treatment and the support member.

[0003] In order to facilitate the hoisting by a crane, a cross beam is designed at the uppermost end of the support member. In the prior art, when heat-treating the expansion section, three or four people are required to lift the expansion section together, sleeve it outside the support member, and then use the crane to lift the support member and the expansion section through the cross beam to the processing position of the heat treatment device. After the heat treatment of the expansion section is completed, it is necessary to cool the support member and the expansion section first, and then the worker uses a hydraulic clamp to separate the expansion section and the support member, and then three or four people lift the expansion section off the support member together. This loading and unloading process is cumbersome and inefficient. Summary of the Invention

[0004] To overcome the above defects, embodiments of the present disclosure provide a heat treatment device for metal workpieces, which solves the technical problem of cumbersome operation and low efficiency during the heat treatment of the expansion section in the prior art.

[0005] According to one aspect, at least one embodiment of the present disclosure provides a heat treatment device for metal workpieces, which is used for heat-treating a support mold and a finished product. The finished product is sleeved outside the support mold, and the support mold has a jacking hole. The support mold and the finished product are separated through the jacking hole. The device is characterized by comprising: A frame, a support shell is provided at the bottom of the frame, and the support shell is used to support the support mold and the finished product; A limit frame, the limit frame has a sliding part and an inserting part. The sliding part is slidably arranged on the support shell. After the sliding part slides in the direction close to the jacking hole, the inserting part can be inserted into the jacking hole; The clamping member is arranged on the frame in a lifting manner. After the clamping member clamps the finished product and rises, it can separate the supporting die from the finished product.

[0006] For example, in a heat treatment device for metal workpieces provided by at least one embodiment of the present disclosure, there are several limiting frames, and the several limiting frames are arranged at intervals along the circumference of the supporting shell. For example, a heat treatment device for metal workpieces provided by at least one embodiment of the present disclosure further includes: A support frame, which has legs and a support portion. The legs are arranged inside the supporting shell, and the support frame is located outside the supporting shell and is used to support the supporting die and the finished product; There are several rotating rods, which are swingably arranged on the support frame. The rotating rod has an abutting portion and a limiting portion, and there is an inclined angle between the abutting portion and the limiting portion. After the supporting die presses down the abutting portion and drives the abutting portion to swing downward, the upward swing of the limiting portion can limit the supporting die.

[0007] For example, a heat treatment device for metal workpieces provided by at least one embodiment of the present disclosure further includes: A lifting plate, which is arranged in the supporting shell in a lifting manner. Both the lifting plate and the supporting shell are provided with guide grooves, and the sliding portion is slidably arranged in the guide groove. After the sliding portion slides, it approaches or moves away from the support frame. The sliding portion has a wedge block, and there is an abutting block on the lower end surface of the lifting plate. After the lifting plate is configured to descend, it drives the abutting block to abut against the inclined surface of the wedge block, so that the wedge block can drive the sliding portion to slide along the guide groove and approach the support frame; An elastic member, one end of which is arranged on the wedge block and the other end is arranged inside the supporting shell. The elastic member is used to provide a force for the wedge block to move away from the support frame.

[0008] For example, in a heat treatment device for metal workpieces provided by at least one embodiment of the present disclosure, the clamping member includes: Two clamping plates, which are both slidably and liftably arranged on the frame. After the two clamping plates slide and approach each other, they clamp the finished product. After the two clamping plates slide and move away from each other, they separate from the finished product.

[0009] For example, in a heat treatment device for metal workpieces provided by at least one embodiment of the present disclosure, there are several support frames, and the several support frames are arranged at intervals. There is a support block on the lower end surface of the clamping plate. After the clamping plate clamps the finished product, the upper end surface of the support block abuts against the lower end surface of the finished product to support the finished product, or the upper end surface of the support block abuts against the lower end surface of the supporting die through the gap between the support frames to support the supporting die.

[0010] For example, a metal workpiece heat treatment device provided by at least one embodiment of the present disclosure, the metal workpiece heat treatment device further includes: A lead screw rotatably arranged on the frame; A mounting seat arranged on the frame in a lifting manner, the lead screw is threadedly arranged on the mounting seat, and after the lead screw rotates, it is used to drive the mounting seat to lift; A telescopic member arranged on the mounting seat, the clamping plate is arranged on the telescopic member, and after the two telescopic members expand and contract, they are used to drive the two clamping plates to approach or move away from each other.

[0011] For example, a metal workpiece heat treatment device provided by at least one embodiment of the present disclosure, the metal workpiece heat treatment device further includes: A heating cylinder arranged on the frame, the heating cylinder has an opening facing downward; A lifting frame arranged on the frame in a lifting manner, the lifting frame is located below the heating cylinder, and the lifting frame has a clamping gap; A guide rail arranged on the frame, the guide rail is located below the lifting frame, the support shell is slidably arranged on the guide rail, and the support shell is configured to slide into the clamping gap and be able to abut against the heating cylinder and close the opening after rising with the lifting frame, and the support shell is configured to move away from the heating cylinder after sliding out of the clamping gap.

[0012] For example, a metal workpiece heat treatment device provided by at least one embodiment of the present disclosure, the metal workpiece heat treatment device further includes: A loading plate arranged at one end of the support shell and slidably arranged on the guide rail, the loading end of the loading plate has an inclined guiding surface, and the support mold and the finished product slide onto the loading plate through the inclined guiding surface.

[0013] For example, in a metal workpiece heat treatment device provided by at least one embodiment of the present disclosure, a plurality of spaced ball bearings are rotatably arranged on the upper end surface of the loading plate.

[0014] The beneficial effects of the embodiments of the present disclosure are as follows: In the present disclosure, the sliding portion of the limiting frame is located at a position away from the insertion hole, and the clamping member is away from the support shell. In the initial state, the support mold sleeved with the finished product is placed on the support shell. After the heat treatment of the finished product is completed, the sliding portion of the limiting frame is slid in the direction close to the insertion hole until the insertion portion is inserted into the insertion hole of the support mold. The clamping member is controlled to approach the support shell, and then the finished product is clamped. The clamping member rises. Due to the limiting effect of the insertion portion and the insertion hole, the support mold remains stationary, and the finished product rises with the clamping member, thereby realizing the separation of the support mold and the finished product.

[0015] Through the cooperation between the insertion part of the limit frame and the insertion hole, and the lifting operation of the clamping part, the rapid and automatic separation of the support mold and the finished product can be achieved, improving the production efficiency. Since both the support mold and the finished product have annular surfaces, several limit frames are designed. The limit frames are arranged on the support shell at intervals along the circumference of the center of the support shell. The limiting effect of several insertion parts and insertion holes can ensure the stable relative position of the support mold and the finished product during the separation process. A strengthening support rod is designed between the sliding part and the insertion part to prevent the insertion part from breaking when separating the support mold and the finished product.

[0024] In addition, in the description of this application, the terms "first", "second", etc. are only used for distinguishing descriptions, and cannot be understood as indicating or implying relative importance.

[0025] Such as Figure 1 , Figure 5 and Figure 6As shown, it shows a heat treatment device for metal workpieces in an embodiment of the present disclosure. The support shell 4 is on the frame 3. The support mold 1 and the finished product 2 are supported on the support shell 4. The sliding part 61 of the limit frame 6 is located at a position far from the jack 101, and the clamping part 7 is far from the support shell 4. In the initial state, the support mold 1 sleeved with the finished product 2 is placed on the support shell 4. After the heat treatment of the finished product 2 is completed, the sliding part 61 of the limit frame 6 is slid in the direction close to the jack 101 until the insertion part 62 is inserted into the jack 101 of the support mold 1. The clamping part 7 is controlled to approach the support shell 4, and then the finished product 2 is clamped. The clamping part 7 rises. Due to the limiting effect of the insertion part 62 and the jack 101, the support mold 1 remains stationary, and the finished product 2 rises with the clamping part 7, thereby realizing the separation of the support mold 1 and the finished product 2.

[0026] Through the cooperation of the insertion part 62 of the limit frame 6 and the jack 101, and the lifting operation of the clamping part 7, the rapid and automatic separation of the support mold 1 and the finished product 2 can be realized, improving the production efficiency. Since both the support mold 1 and the finished product 2 have annular surfaces, several limit frames 6 are designed. The limit frames 6 are arranged at intervals along the circumference of the center of the support shell 4 on the support shell 4. The limiting effect of several insertion parts 62 and jacks 101 can ensure the relative position stability of the support mold 1 and the finished product 2 during the separation process. A strengthening support rod is designed between the sliding part 61 and the insertion part 62 to prevent the insertion part 62 from breaking when separating the support mold 1 and the finished product 2.

[0027] There are several support frames 5, and several support frames 5 are arranged at intervals on the support shell 4. The support frames 5 arranged at intervals can lift the support mold 1 and the finished product 2, and the gap between the support frames 5 is convenient for the support mold 1 and the finished product 2. When using a forklift to remove the heat-treated support mold 1 and the finished product 2 from the support frames 5, the fork part of the forklift can extend into the gap between the support frames 5. After the fork part is lifted, the support mold 1 and the finished product 2 can be lifted from the bottom end surface of the support mold 1, realizing the blanking of the support mold 1 and the finished product 2. The rotating rod 16 rotates on the supporting part 52. When preventing the support mold 1 and the finished product 2, the support mold 1 presses down on the abutting part 161, driving the abutting part 161 to swing downward, and the limiting part 162 to swing upward. Several limiting parts 162 are arranged at intervals along the circumference on several support frames 5. After the limiting part 162 swings upward, it forms a limit on the support mold 1 to prevent the support mold 1 from being misaligned after the support shell 4 moves.

[0028] As Figure 3As shown in the figure, the support shell 4 has a shell body 41 and a fixing plate 42. An installation space 421 is formed between the shell body 41 and the fixing plate 42 of the support shell 4. The lifting plate 8 is installed in the installation space 421, and the leg 51 of the support frame 5 passes through the fixing plate 42 and the lifting plate 8 and is fixed on the inner wall of the installation space 421 to ensure that the leg 51 and the lifting plate 8 can move up and down relative to each other. The fixing plate 42 is made of heat-insulating material. Through the protection of the fixing plate 42, during the production of the finished product 2 and the heat treatment process, the temperature in the installation space 421 will not be too high, so as not to affect the driving member to drive the lifting plate 8 to move up and down. When it is necessary to support the support mold 1 and the finished product 2, control the lifting plate 8 to rise so that the support part 52 rises to a position equal to or higher than the insertion part 62; when the heat treatment is completed and it is necessary to separate the finished product 2 and the support mold 1 and remove the support mold 1 and the finished product 2 from the support shell 4, control the lifting plate 8 to descend.

[0029] The lifting plate 8 is arranged in the installation space 421 of the support shell 4, making the structure of the whole device more compact and reducing the occupied space. Through the relative lifting of the leg 51 and the fixing plate 42, it can ensure that the support frame 5 supports the support mold 1 and the finished product 2.

[0030] As Figure 3 shown in the figure, guide grooves 422 are machined on both the fixing plate 42 and the lifting plate 8, and the sliding part 61 of the limit frame 6 is installed in the guide grooves 422 to ensure that the sliding part 61 can slide in the guide grooves 422. When the sliding part 61 slides and moves away from the support frame 5, at this time, the support mold 1 sleeved with the finished product 2 can be placed on the support frame 5, or the separated support mold 1 can be removed from the support frame 5. A baffle can be designed on the sliding part 61, and the length of the baffle is more than twice the length of the guide groove 422. The sliding part 61 is located at the center of the baffle. In this way, no matter what part of the guide groove 422 the sliding part 61 slides to, the hot air will not enter the installation space 421 through the guide groove 422. The baffle is also made of heat-insulating material. If the opening position of the guide groove 422 is not sufficient to install a baffle more than twice as long, the part of the baffle close to the inner wall of the installation space 421 can be designed as a telescopic structure. When the sliding part 61 slides close to the support frame 5, the telescopic baffle extends, which can also ensure that the guide groove 422 is always in a sealed state.

[0031] The setting of the guide groove 422 provides guidance for the sliding of the sliding part 61, facilitating the insertion or detachment of the insertion part 62 into or from the insertion hole 101. The sliding part 61 slides in the guide groove 422, which can ensure its sliding track, so that the insertion part 62 can accurately insert into the insertion hole 101, improving the positioning accuracy of the device.

[0032] As Figure 3As shown, a wedge block 611 is installed on the sliding part 61, and an abutting block 81 is installed on the lower end surface of the lifting plate 8. When the lifting plate 8 descends, the abutting block 81 descends accordingly and abuts against the inclined surface of the wedge block 611. Due to the action of the inclined surface of the wedge block 611, the abutting block 81 will push the wedge block 611, so that the wedge block 611 drives the sliding part 61 to slide along the guide groove 422 and approach the support frame 5. A spring can be designed between the wedge block 611 and the inner wall of the installation space 421. After the lifting plate 8 ascends, due to the action of the spring, the sliding part 61 is driven by the wedge block 611 to move away from the support frame 5.

[0033] The sliding control of the sliding part 61 is realized through the descending action of the lifting plate 8, enabling linkage among the various components of the device, reducing additional control mechanisms, and lowering the complexity and cost of the device. This linkage method enables the device to achieve automatic operation, improve production efficiency, and reduce manual intervention.

[0034] As Figure 4 shown, the sliding of the two clamping plates 71 on the frame 3 is controlled. When the two clamping plates 71 approach each other, the finished product 2 can be clamped; when the two clamping plates 71 move away from each other, they are separated from the finished product 2. After the insertion part 62 is inserted into the insertion hole 101, only the finished product 2 is clamped by the two clamping plates 71. The clamping plates 71 can be arc-shaped plates. After the two clamping plates 71 approach each other, a clamping space is formed, and the finished product 2 is clamped within the clamping space. The clamping plates 71 surround the outer peripheral wall of the finished product 2. By controlling the two clamping plates 71 to ascend, due to the limiting effect of the insertion part 62 and the insertion hole 101, the support die 1 remains stationary, and the finished product 2 ascends with the clamping plates 71, thus realizing the separation of the finished product 2 from the support die 1.

[0035] The sliding setting of the two clamping plates 71 can be adjusted according to the size of the finished product 2 to ensure that the finished product 2 can be clamped and prevent the finished product 2 from falling during the separation process. The separation of the finished product 2 from the support die 1 is realized through the ascending operation of the clamping plates 71, with simple and efficient operation.

[0036] As Figure 4As shown, after the clamping plate 71 clamps the finished product 2, in order to prevent the finished product 2 from falling off, through the avoidance of the jacking hole 101, the upper end surface of the support block 711 abuts against the lower end surface of the finished product 2, thereby supporting the finished product 2; when the heat treatment is completed and the support mold 1 needs to be removed from the support frame 5, the support mold 1 is clamped by the clamping member 7, and the support block 711 is clamped on the lower end surface of the support mold 1. After the clamping member 7 descends, the support mold 1 can be removed from the support frame 5. Through the gap between the support frames 5, the upper end surface of the support block 711 abuts against the lower end surface of the support mold 1, thereby supporting the support mold 1. The support block 711 only supports a part of the lower end surface of the finished product 2 and does not extend into the interior of the finished product 2 through the lower end surface. The purpose is to prevent the support block 711 from abutting against the upper end surface of the jacking hole 101 on the support mold 1 during the rising process of the finished product 2, resulting in difficulty in separating the finished product 2 and the support mold 1. After the support block 711 supports the corresponding workpiece, subsequent separation operations are carried out to ensure the stability of the separation process.

[0037] The setting of the support block 711 enables the clamping plate 71 to not only clamp the finished product 2 but also support the finished product 2 or the support mold 1 as needed, improving the versatility of the device. The supporting function of the support block 711 can ensure the stability of the workpiece during the separation process and avoid the failure of separation or damage to the workpiece caused by the shaking of the workpiece.

[0038] As Figure 4 shown, by rotating the lead screw 12, due to the threaded fit between the lead screw 12 and the mounting seat 13, the rotation of the lead screw 12 will drive the mounting seat 13 to move up and down on the frame 3. The telescopic member 14 is installed on the mounting seat 13, and the clamping plate 71 is installed on the telescopic member 14. By controlling the telescopic movement of the telescopic member 14, the two clamping plates 71 are driven to approach or move away from each other, realizing the clamping and releasing operations of the finished product 2.

[0039] The rotation of the lead screw 12 can control the lifting position of the mounting seat 13, thereby controlling the lifting height of the clamping plate 71. The setting of the telescopic member 14 enables the two clamping plates 71 to approach or move away from each other flexibly, adapting to finished products 2 of different sizes and improving the versatility of the device.

[0040] As Figure 4 shown, the heating cylinder 9 is fixed on the frame 3 with the opening facing downwards; the lifting frame 10 is installed on the frame 3 so that it can move up and down on the frame 3; the guide rail 11 is installed on the frame 3, and the support shell 4 is slidably arranged on the guide rail 11. The support shell 4 is controlled to slide into the clamping gap 102 of the lifting frame 10 along the guide rail 11, and then the lifting frame 10 is controlled to rise so that the support shell 4 abuts against the heating cylinder 9 to close the opening of the heating cylinder 9. At this time, heat treatment can be carried out on the support mold 1 and the finished product 2. After the heat treatment is completed, the lifting frame 10 is controlled to descend, and then the support shell 4 is controlled to slide out of the clamping gap 102 along the guide rail 11 so that the support shell 4 is away from the heating cylinder 9.

[0041] Through the cooperation of the support shell 4 and the heating cylinder 9, a relatively enclosed heating space can be formed, improving the heating efficiency and reducing heat loss. The support shell 4 can slide on the guide rail 11, facilitating the feeding of workpieces into the heating cylinder 9 for heat treatment and the removal of heat-treated workpieces, thus improving the operation flexibility.

[0042] As Figure 4 shown, the loading plate 15 is slidably arranged on the guide rail 11. After the support shell 4 fixed at one end of the support shell 4 slides along the guide rail 11, it drives the loading plate 15 to slide and ensures that the loading end of the loading plate 15 has an inclined guiding surface 151.

[0043] When loading is required, the support die 1 and the finished product 2 are slid into the loading plate 15 through the inclined guiding surface 151 of the loading plate 15. Then, the loading plate 15 is controlled to slide, and the finished product 2 is conveyed to a position where the clamping member 7 can clamp it. After the clamping member 7 clamps the finished product 2 and drives the finished product 2 to rise, the support die 1 is slid into the loading plate 15, the finished product 2 is sleeved on the support die 1, and then the support die 1 and the finished product 2 are clamped together and lifted. The support die 1 and the finished product 2 to be heat-treated are placed on the support frame 5 to complete the loading. When unloading is required, the two clamping plates 71 clamp the finished product 2. Through the limitation of the insertion part 62, the finished product 2 is separated from the support die 1. At this time, the finished product 2 is located above the support die 1. The support die 1 on the loading plate 15 can be pushed out of the loading plate 15 through the inclined guiding surface 151, and then the finished product 2 is placed on the loading plate 15 and pushed out of the loading plate 15 through the inclined guiding surface 151 to complete the unloading and the separation of the support die 1 and the finished product 2.

[0044] The inclined guiding surface 151 of the loading plate 15 enables the workpieces to easily slide into the loading plate 15, facilitating the loading operation and improving the loading efficiency.

[0045] During the loading operation, the support die 1 and the finished product 2 are placed on the loading plate 15. Since a number of spaced ball bearings 152 are rotatably arranged on the upper end surface and the inclined guiding surface 151 of the loading plate 15, when the workpieces slide on the loading plate 15, the ball bearings 152 will rotate accordingly, reducing the friction between the workpieces and the loading plate 15. At the same time, the ball bearings 152 are arranged at intervals, and the ball bearings 152 have a lifting effect, which can enable the support block 711 to be inserted into the gap between the finished product 2 or the support die 1 and the loading plate 15, enabling the support block 711 to achieve a supporting effect.

[0046] The setting of the ball bearings 152 reduces the friction between the workpieces and the loading plate 15, enabling the workpieces to be more smooth during the loading process. The reduction of friction reduces the wear of the workpieces and the loading plate 15 and extends the service life of the device.

[0047] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present disclosure and not to limit them. Although the present disclosure has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present disclosure can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present disclosure, and they should all be covered by the scope of the claims of the present disclosure.
