Description

Technical Field

[0001] This utility model relates to the field of cast steel production technology, specifically a heat treatment device for cast steel parts. Background Technology

[0002] Heat treatment of cast steel parts refers to the process of heating, holding and cooling steel parts formed by casting. It is an important technical means to improve the mechanical properties, machinability or service performance of steel parts by controlling the internal structure of the steel parts.

[0003] Chinese patent application number CN202420300180.4 discloses a heat treatment device for cast steel parts, including a base. A bottom groove is formed at one end of the upper surface of the base. An installation groove is formed centrally on the upper surface of the bottom groove, and an adjustment mechanism is installed within the installation groove. A sealing plate is slidably connected to the upper surface of the bottom groove. Through the cooperation of the holding box, the sealing plate, the adjustment mechanism, and the base, the rotating threaded rod drives the slider to move within the installation groove, facilitating the sealing of the opening of the heating furnace box by the sealing plate. This prevents heat loss during the heating of the steel casting, improves the heating effect of the steel casting, and avoids burns caused by manually opening and closing the sealing plate, improving the safety of the workers. The partition plate and the holding box separate and limit the steel casting, preventing it from falling out of the heating furnace box, extending the service life of the device, and preventing damage to the device from falling steel castings.

[0004] However, in the existing technology, the partition plate can only be used to limit the size of cast steel parts. When heat treating different cast steel parts, it is necessary to replace the container and the partition plate. The scope of application is small, the work efficiency is low, and it is not conducive to the promotion and application in actual production.

[0005] In summary, this utility model provides a heat treatment device for cast steel parts to solve the above problems. Utility Model Content

[0006] This utility model provides a heat treatment device for cast steel parts, which restricts the cast steel parts by setting clamps in different directions, so as to solve the problems of limited applicability and frequent replacement of parts in the prior art.

[0007] The specific technical solution of this utility model is as follows:

[0008] A heat treatment apparatus for cast steel parts includes a heating furnace, a support frame provided on the inner side of the heating furnace, a support rod fixedly connected to the upper part of the support frame, a base fixedly connected to the inner side of the support rod, a processing box slidably connected to the inner side of the base, and a cast steel part provided on the inner side of the processing box. A first clamping plate is provided on one side of the cast steel part, a first sliding column is fixedly connected to the side of the first clamping plate away from the cast steel part, a first positioning frame is slidably connected to the side of the first sliding column, the bottom of the first positioning frame is detachably connected to the processing box, a first transmission plate is rotatably connected to the side of the first sliding column away from the first clamping plate, a first control plate is rotatably connected to the end of the first transmission plate away from the first sliding column, and the bottom end of the first control plate is rotatably connected to the first positioning frame.

[0009] In this invention, a heating furnace is used for heat treatment of cast steel parts; a support frame and support rod are used to fix the base in the middle of the heating furnace, making the position of the cast steel parts more conducive to heating; the processing box can be pulled out of the base, thus leaving the heating furnace, making it easy to put the cast steel parts in; there is a certain friction between the first control plate and the first positioning frame, making it less prone to loosening and slipping, which facilitates fixing the cast steel parts; when the worker rotates the first control plate, an inclined thrust is applied to the first transmission plate, causing the first transmission plate to rotate relative to the first sliding column, and pushing the first sliding column to slide along the first positioning frame, thereby pushing the first clamping plate to move towards the cast steel parts and clamping the cast steel parts; during this process, the movement distance of the first clamping plate is freely adjustable by the first control plate, thus adapting to cast steel parts of different sizes, solving the problem of limited applicability and the need for frequent component replacement in the prior art.

[0010] In a preferred embodiment, a second clamping plate is provided on the side of the first clamping plate, a second sliding column is provided on the side of the second clamping plate away from the first clamping plate, a second positioning frame is slidably connected to the side of the second sliding column, the bottom of the second positioning frame is detachably connected to the processing box, a second transmission plate is rotatably connected to the side of the second sliding column away from the second clamping plate, a second control plate is rotatably connected to the end of the second transmission plate away from the second sliding column, and the bottom end of the second control plate is rotatably connected to the second positioning frame.

[0011] In this utility model, the second clamping plate is used to clamp the cast steel part from the side, thereby cooperating with the first clamping plate to adapt to the complex shape of different cast steel parts and avoid problems such as shaking and falling off when the round or other cast steel parts are clamped by a single clamping plate; the connection between the second sliding column and the second clamping plate is inclined, so that the second clamping plate moves obliquely to adapt to the narrow space of the processing box.

[0012] In a preferred embodiment, the first transmission plate is rotatably connected to the middle of the first control plate, and two sets of the first transmission plate are symmetrically arranged on both sides of the first sliding column.

[0013] In a preferred embodiment, the second transmission plate is rotatably connected to the middle of the second control plate, and two sets of the second transmission plate are symmetrically arranged on both sides of the second sliding column.

[0014] In this invention, when the first and second transmission plates rotate, the forces they experience are inclined, thus pushing the first and second sliding columns to move while rotating; however, when the first and second sliding columns are subjected to the thrust from the cast steel parts, the forces applied to the first and second transmission plates are horizontal, making it difficult to push the first and second control plates to move in the opposite direction.

[0015] In a preferred embodiment, a partition is provided on one side of the processing box, and a limit post is fixedly connected to the bottom of the partition.

[0016] In a preferred embodiment, a limiting hole is provided on the side of the processing box near the limiting post, and the limiting post and the limiting hole are detachably connected. A slot is provided on the side of the processing box near the partition, and the partition and the slot are detachably connected.

[0017] In a preferred embodiment, the base has a through hole on the side near the limiting post, and the limiting post is detachably connected to the through hole.

[0018] In this invention, a partition plate is inserted into a slot to restrict the movement of the cast steel parts inside the processing box, and cooperates with the first clamping plate and the second clamping plate; a limiting post is inserted into both the limiting hole and the through hole, thereby fixing the processing box relative to the base and preventing the processing box from shaking during heat treatment.

[0019] In a preferred embodiment, a furnace door is rotatably connected to the side of the heating furnace.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. This utility model uses a first transmission plate to push the first sliding column and the first clamping plate to move and clamp the cast steel part. The moving distance can be freely adjusted, which can adapt to cast steel parts of different sizes and solves the problems of limited applicability and frequent replacement of parts in the prior art.

[0022] 2. This utility model uses a second clamping plate to cooperate with the first clamping plate, which can clamp the cast steel parts from the side, adapting to the complex shapes of different cast steel parts, and avoiding the shaking and falling off of round or other cast steel parts when clamped by a single clamping plate.

[0023] 3. This utility model restricts the movement of cast steel parts inside the processing box by inserting a partition into a slot, and further fixes the workpiece in conjunction with the clamping plate. At the same time, the limiting post is inserted into the limiting hole of the processing box and the through hole of the base, so that the processing box and the base are relatively fixed and avoid shaking during heat treatment.

[0032] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0033] like Figure 1-7As shown, this utility model provides a heat treatment device for cast steel parts, including a heating furnace 1. A support frame 11 is provided on the inner side of the heating furnace 1. A support rod 12 is fixedly connected to the upper part of the support frame 11. A base 2 is fixedly connected to the inner side of the support rod 12. A processing box 3 is slidably connected to the inner side of the base 2. A cast steel part 4 is provided on the inner side of the processing box 3. A first clamping plate 31 is provided on one side of the cast steel part 4. A first sliding column 33 is fixedly connected to the side of the first clamping plate 31 away from the cast steel part 4. A first positioning frame 32 is slidably connected to the side of the first sliding column 33. The bottom of the first positioning frame 32 is detachably connected to the processing box 3. A first transmission plate 34 is rotatably connected to the side of the first sliding column 33 away from the first clamping plate 31. A first control plate 35 is rotatably connected to the end of the first transmission plate 34 away from the first sliding column 33. The bottom end of the first control plate 35 is rotatably connected to the first positioning frame 32.

[0034] A second clamping plate 5 is provided on the side of the first clamping plate 31. A second sliding post 51 is provided on the side of the second clamping plate 5 away from the first clamping plate 31. A second positioning frame 52 is slidably connected to the side of the second sliding post 51. The bottom of the second positioning frame 52 is detachably connected to the processing box 3. A second transmission plate 53 is rotatably connected to the side of the second sliding post 51 away from the second clamping plate 5. A second control plate 54 is rotatably connected to the end of the second transmission plate 53 away from the second sliding post 51. The bottom end of the second control plate 54 is rotatably connected to the second positioning frame 52.

[0035] The first transmission plate 34 is rotatably connected to the middle of the first control plate 35, and two sets of the first transmission plate 34 are symmetrically arranged on both sides of the first sliding column 33.

[0036] The second transmission plate 53 is rotatably connected to the middle of the second control plate 54, and two sets of the second transmission plate 53 are symmetrically arranged on both sides of the second sliding column 51.

[0037] A partition 6 is provided on one side of the processing box 3, and a limit post 61 is fixedly connected to the bottom of the partition 6.

[0038] A limiting hole 36 is provided on the side of the processing box 3 near the limiting post 61. The limiting post 61 and the limiting hole 36 are detachably connected. A slot 37 is provided on the side of the processing box 3 near the partition 6. The partition 6 and the slot 37 are detachably connected.

[0039] The base 2 has a through hole 21 on the side near the limiting post 61, and the limiting post 61 and the through hole 21 are detachably connected.

[0040] A furnace door 7 is rotatably connected to the side of the heating furnace 1.

[0041] The working principle of this utility model is as follows: the worker first opens the furnace door 7, pulls the processing box 3 out from the inside of the base 2, and places the cast steel part 4 inside the processing box 3.

[0042] Insert the partition 6 into the slot 37 of the processing box 3. The limiting post 61 at the bottom of the partition 6 is aligned with the limiting hole 36 of the processing box 3. After insertion, the lateral movement of the cast steel part 4 in the processing box 3 is restricted.

[0043] Rotate the first control plate 35 (the bottom end of which is rotatably connected to the first positioning frame 32). Since the first transmission plate 34 is rotatably connected to the middle of the first control plate 35 and is symmetrically arranged on both sides, the first control plate 35 applies an inclined thrust to the first transmission plate 34 when rotating.

[0044] The first transmission plate 34 pushes the first sliding column 33 to slide along the first positioning frame 32, causing the first clamping plate 31 to move towards the cast steel part 4 until it clamps one side of the cast steel part 4.

[0045] The friction between the first control plate 35 and the first positioning frame 32 can prevent loosening and ensure a stable clamping state.

[0046] Similarly, rotating the second control plate 54 pushes the second sliding column 51 to slide along the second positioning frame 52 through the second transmission plate 53, so that the second clamping plate 5 is clamped from the side of the cast steel part 4 in conjunction with the first clamping plate 31.

[0047] The synergistic effect of the two side clamps can accommodate cast steel parts with complex shapes such as round and irregular shapes, and avoid shaking or falling off caused by clamping on one side.

[0048] After confirming that the cast steel part 4 is fixed, slide the processing box 3 into the inner side of the heating furnace 1 along the base 2, then align the limiting post 61 with the through hole 21 of the base 2, insert it to fix the processing box 3 relative to the base 2, and close the furnace door 7.

[0049] The support frame 11 and support rod 12 fix the base 2 in the middle of the heating furnace 1, so that the cast steel part 4 is in a position for uniform heating, and the heating furnace 1 is started to heat treat the cast steel part 4.

[0050] After heat treatment is completed, open furnace door 7 and remove processing box 3.

[0051] Rotate the first control plate 35 and the second control plate 54 in the opposite direction to loosen the first clamping plate 31 and the second clamping plate 5, and remove the cast steel part 4.

[0052] If it is necessary to process cast steel parts 4 of different sizes, the movement distance of the first clamping plate 31 and the second clamping plate 5 can be changed by adjusting the rotation angle of the first control plate 35 and the second control plate 54, so that it can adapt to workpieces of different specifications without replacing parts.

[0053] The first transmission plate 34 and the second transmission plate 53 are symmetrically arranged in the middle of the control plate. When the control plate is rotated, the transmission plate is tilted by force to push the sliding column to move; while the horizontal thrust applied by the cast steel part 4 after clamping is difficult to reverse drive the control plate to rotate, ensuring the clamping force is maintained.

[0054] The first positioning frame 32, the second positioning frame 52, and the partition 6 are all detachably connected to the processing box 3, which makes it easy to adjust the position of the clamping plate or replace the partition 6 according to the shape of the cast steel part 4, thus improving the flexibility of the device.

[0055] The embodiments of this utility model are given for the purpose of illustration and description. Although embodiments of this utility model have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting this utility model. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of this utility model.
