[0017] The beneficial effects of this invention are as follows: 1.

[0022] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0023] Example 1: As Figure 1-2 As shown in the figure, a stainless steel wire heat treatment device according to an embodiment of the present invention includes a heat treatment furnace 1, a heating unit is provided inside the heat treatment furnace, a furnace door 11 is provided at the outlet of the heat treatment furnace 1, and further includes: a preheating chamber 2 provided at the outlet of the heat treatment furnace 1, a number of sets of stainless steel wires are placed inside the preheating chamber 2; and a traveling mechanism 3 for pushing the stainless steel wires in and out between the preheating chamber 2 and the heat treatment furnace 1, the traveling mechanism 3 including a traveling trolley 31.

[0024] Specifically, the heat treatment furnace 1 is preferably, but not limited to, a box-type resistance furnace, wherein the heating unit is a resistance heating device, and the traveling mechanism 3 is preferably, but not limited to, a trolley device, wherein the traveling trolley 31 travels between the heat treatment furnace 1 and the preheating chamber 2; when performing heat treatment such as annealing on stainless steel wire, a group of stainless steel wire is placed on the traveling mechanism 3, the furnace door 11 is opened, and the traveling trolley 31 is pushed into the heat treatment furnace 1 by manual or electric means, and after closing the furnace door 11, the heat treatment furnace 1 is started to perform heat treatment on the stainless steel wire.

[0025] After the heat treatment is completed, the furnace door 11 is opened, and the heat-treated high-temperature stainless steel wires are placed in the preheating chamber 2 for air cooling. Another set is placed on the traveling trolley 31 for further heat treatment. During the heat treatment process, the heat emitted by the air-cooled stainless steel wires in the preheating chamber 2 is used to preheat the remaining stainless steel wires to be treated. Preheating not only helps to improve the quality of the steel wires and reduce the heating time required for subsequent heat treatment, thus improving production efficiency, but also enables the reuse of the heat in the heat-treated steel wires, improving the problem of heat energy waste.

[0026] It should be noted that the preheating chamber 2 in this embodiment adopts a closed structure. Depending on the specific requirements of the air cooling method after heat treatment, the preheating chamber 2 may also adopt an open or other structures.

[0027] like Figure 2-4As shown, the preheating chamber 2 is equipped with a replacement part 4, which includes: a turntable 41 that is rotatably installed in the preheating chamber 2; several hanging plates 42 that are hung on the turntable 41, the several hanging plates 42 being evenly distributed in a longitudinal ring, and the top of the hanging plates 42 being rotatably connected to the turntable 41; and a storage frame 43 provided in the hanging plate 42, which is used to place stainless steel wire.

[0028] Specifically, a support frame is provided inside the preheating chamber 2, and the turntable 41 is rotatably mounted on the support frame. The number of storage frames 43 is odd, and the overall center of gravity of the hanging plate 42 is low. The storage frames 43 are located inside the lower half of the hanging plate 42. By setting the hanging plate 42, the hanging plate 42 and the storage frames 43 maintain their posture during the rotation of the turntable 41. Taking the setting of three storage frames 43 on the turntable 41 as an example, in... Figure 2 In the middle, the lower right storage box 43 is the working station, and the other storage boxes 43 are waiting stations. The storage boxes 43 in the working station are aligned with the heat treatment furnace 1 so that the storage box 43 can be directly sent into the heat treatment furnace 1.

[0029] like Figure 2-5 As shown, the walking mechanism 3 also includes: a slide rail 32 for guiding the walking trolley 31; a push plate 33 located at the end of the walking trolley 31 for pushing the storage frame 43, the push plate 33 having a unidirectional rotating structure, the bottom of the hanging plate 42 having a notch corresponding to the push plate 33, and the push plate 33 being located on the outside of the turntable 41.

[0030] Specifically, the bottom of the hanging plate 42 is provided with two ear plates for supporting the storage frame 43. There is a gap between the two ear plates, which is open from left to right. The slide rail 32 is located inside the preheating chamber 2 and extends into the heat treatment furnace 1. When the heat treatment furnace 1 and the preheating chamber 2 are placed on the ground, the slide rail 32 and the traveling trolley 31 are also placed on the ground. The push plate 33 and the turntable 41 never contact each other. The traveling trolley 31 is located below the storage frame 43 in the working position. Initially, the pusher plate 33 is located to the left of the storage frame 43 in the working station. The steel wire to be processed is placed into each storage frame 43. During heat treatment, the furnace door 11 is opened and the traveling trolley 31 is pushed to the right. The traveling trolley 31 pushes the storage frame 43 in the working station through the pusher plate 33 until the storage frame 43 is separated from the hanging plate 42 and stops on the traveling trolley 31. Then, the traveling trolley 31 sends the storage frame 43 containing the stainless steel wire into the heat treatment furnace 1. After the storage box 43 in the work station is removed, it becomes empty. The overall center of gravity of the turntable 41 changes and it rotates automatically until the empty hanging plate 42 rotates to the top. Then the next hanging plate 42 loaded with the storage box 43 rotates into the work station. After heat treatment, the traveling trolley 31 moves left from the heat treatment furnace 1 into the preheating chamber 2. First, the heat-treated storage frame 43 is placed in the empty hanging plate 42 at the top of the turntable 41. Then, the traveling trolley 31 continues to move left to its initial position, and the pusher plate 33 also moves to the left side of the workstation. Next, the traveling trolley 31 is pushed right to send the next set of storage frames 43 containing steel wire into the heat treatment furnace 1. This allows for continuous heat treatment. During air cooling, the heat-treated stainless steel wire preheats the remaining stainless steel wire. After air cooling, the air-cooled stainless steel wire is removed from the storage frame 43, and new steel wire to be treated is placed in. The removal and placement of the stainless steel wire occurs during the operation of the heat treatment furnace 1, without taking up additional time. Therefore, the continuity of heat treatment for multiple sets of steel wire can be further improved, increasing overall work efficiency.

[0031] It should be noted that, in order to further improve the stability of the turntable 41, a damping element can be installed on the rotation axis of the turntable 41 so that the turntable 41 can maintain a stable state of not rotating when three storage boxes 43 are loaded on it. The turntable 41 will only rotate due to the change of center of gravity after the storage box 43 in the work station is removed.

[0032] like Figure 3-7 As shown, it also includes a pusher 5, which is used to push the storage frame 43 located on the traveling trolley 31 upward. The pusher 5 includes a top plate 51 movably disposed at the top of the traveling trolley 31.

[0033] Specifically, the top plate 51 is placed horizontally and can be moved in the longitudinal direction to push the heat-treated storage frame 43 upward into the empty hanging plate 42 at the top of the turntable 41.

[0034] like Figure 2 As shown, the replacement unit 4 also includes a guide plate 44 disposed inside the preheating chamber 2. The guide plate 44 is used to guide the storage frame 43 on the top plate 51 into the hanging plate 42. The guide plate 44 is inclined and the bottom end of the guide plate 44 is provided with a through groove corresponding to the top plate 51. The width of the through groove is smaller than the width of the storage frame 43.

[0035] Specifically, the end of the guide plate 44 near the hanging plate 42 is inclined downwards, and the guide plate 44 is provided with a guide groove to guide the storage frame 43. The width of the groove is greater than the width of the top plate 51. Figure 2After the heat treatment is completed, the traveling trolley 31 moves to the left. After the traveling trolley 31 moves to the outside of the heat treatment furnace 1, the top plate 51 is raised, so that the heat-treated storage frame 43 is above the guide plate 44 and the top plate 51 is in the through groove. After the traveling trolley 31 and the top plate 51 continue to move to the left, the storage frame 43 continues to move to the left in the guide plate 44. The storage frame 43 slides along the guide groove in the guide plate 44 to the empty hanging plate 42 at the top of the turntable 41. In this way, the function of transferring the heat-treated storage frame 43 to the hanging plate 42 at the top of the turntable 41 is realized.

[0036] like Figure 3-7 As shown, the jacking part 5 also includes several sets of parallel rotating plates 52, with the two ends of the rotating plates 52 rotatably connected to the traveling trolley 31 and the top plate 51, respectively.

[0037] Specifically, taking two sets of rotating plates 52 as an example, the two sets of rotating plates 52, top plate 51 and traveling trolley 31 form a parallelogram mechanism. After the rotating plate 52 rotates, it can drive the top plate 51 to rotate, and the top plate 51 always remains horizontal during the rotation, thereby ensuring the stability of the storage frame 43 located on the top plate 51.

[0038] like Figure 3-8 As shown, the rotating plate 52 includes: an outer plate 521 rotatably disposed at the top of the traveling trolley 31; an inner plate 522 rotatably disposed at the bottom of the top plate 51, the inner plate 522 being movably inserted into the interior of the outer plate 521; a slot 523 disposed on the inner plate 522; a locking block 524 slidably disposed at the bottom of the outer plate 521; and a spring 525 disposed on the outer plate 521 for pushing the locking block 524 into the slot 523.

[0039] Specifically, since the rotating plate 52 is a rotating motion, the overall movement trajectory of the top plate 51 is an arc shape. In order to achieve repetitive work, after the top plate 51 sends the placement frame 43 to the guide plate 44 after rotation, it needs to rotate back to reset. If the length of the rotating plate 52 remains unchanged, the rotating plate 52 may contact the placement frame 43 in the guide plate 44 when rotating and drive the placement frame 43 to move to the right, which may prevent the placement frame 43 from sliding into the hanging plate 42. In order to improve this problem, the rotating plate 52 is set to be telescopic. Initially, the inner plate 522 extends outward relative to the outer plate 521, and the locking block 524 is inserted into the locking slot 523 to fix the inner plate 522. The overall length of the rotating plate 52 is relatively long and the length is kept fixed so as to push the placement frame 43 upward into the guide plate 44. After the top plate 51 moves upward, the inner plate 522 is located above the outer plate 521. When the rotating plate 52 rotates back to its original position, the locking block 524 is removed, and the inner plate 522 automatically retracts into the interior of the outer plate 521 under the action of gravity. The overall length of the rotating plate 52 is shortened, causing the top plate 51 to move down below the guide plate 44. Then, when the rotating plate 52 rotates back, the top plate 51 does not contact the guide plate 44, and naturally does not contact the storage frame 43 located in the guide plate 44, thus improving the above-mentioned problem.

[0040] like Figure 6 As shown, after the top plate 51 moves down and stops on the traveling trolley 31, the rotating plate 52 is tilted, and the inner plate 522 is lower than the outer plate 521.

[0041] Specifically, after the rotating plate 52 rotates back to its initial state, the rotating plate 52 is tilted, with the inner plate 522 located below the outer plate 521. Under the action of gravity, the inner plate 522 automatically extends outward. After the inner plate 522 extends outward, the locking block 524 is pushed back into the locking slot 523 by the spring 525, and the rotating plate 52 automatically returns to a state where its overall length is longer and remains fixed, without the need for manual operation.

[0042] Example 2: Figure 3-5 As shown in the comparative embodiment one, another embodiment of the present invention is as follows: the pusher 5 further includes: a driven plate 53 fixed to the bottom of the outer plate 521; a support platform 54 provided on the slide rail 32; a rotatable lever 55 provided on the support platform 54, the lever 55 having a unidirectional rotation structure, after the traveling trolley 31 moves from the heat treatment furnace 1 into the preheating chamber 2, the lever 55 contacts the driven plate 53 and pushes the rotating plate 52 to rotate; and a horizontal plate 56 fixed to the support platform 54, the horizontal plate 56 being used to push the rotating plate 52 to rotate.

[0043] Specifically, after the heat treatment is completed, the traveling trolley 31 moves to the left. After the traveling trolley 31 moves to the left, the driven plate 53 contacts the lever plate 55. The lever plate 55 squeezes the driven plate 53, causing the rotating plate 52 to start rotating. After the rotating plate 52 rotates, it drives the top plate 51 to move upward, sending the storage frame 43 into the guide plate 44. After the trolley 31 continues to move to the left, the driven plate 53 separates from the lever plate 55, and the horizontal plate 56 contacts the rotating plate 52. The horizontal plate 56 pushes the rotating plate 52 to rotate, and after rotating, the rotating plate 52 stops on the trolley 31. Then, the trolley 31 can pass under the storage frame 43 in the workstation until the trolley 31 moves to the initial position to the left. In this way, the function of automatic rotation and turning of the rotating plate 52 is realized during the movement of the trolley 31 after the heat treatment is completed.

[0044] It should be noted that the position, specific structure and size of the horizontal plate 56 can be selected according to the actual situation. Other structures that allow the horizontal plate 56 to drive the rotating plate 52 to rotate without affecting the movement of the traveling trolley 31 are also suitable for the manufacture of the horizontal plate 56. Multiple lever plates 55 can be set. The number and position of the lever plates 55 correspond to the driven plate 53 so that multiple rotating plates 52 can contact the lever plates 55 at the same time and rotate at the same time. This can improve the problem of stress concentration on a single rotating plate 52 caused by the force on a single rotating plate 52.

[0045] like Figure 3-8 As shown, the pusher 5 also includes: a protruding rod 57 fixed to the locking block 524; a pressure plate 58 fixed to the bottom of the top plate 51, the bottom of the pressure plate 58 being provided with a ramp for pushing the protruding rod 57 to move; during the rotation of the rotating plate 52 and the upward movement of the top plate 51, the pressure plate 58 contacts the protruding rod 57 and pushes the locking block 524 to separate from the locking groove 523.

[0046] Specifically, when the rotating plate 52 rotates and drives the top plate 51 to move upward, the rotating plate 52 moves relative to the top plate 51. The protruding rod 57 rotates together with the rotating plate 52. Initially, the pressure plate 58 does not contact the protruding rod 57. The rotating plate 52 rotates to become vertical, and after the top plate 51 moves upward to send the storage frame 43 into the guide plate 44, the protruding rod 57 contacts the lower end of the pressure plate 58. The pressure plate 58 drives the protruding rod 57 and the locking block 524 to move through the bottom slope, so that the locking block 524 separates from the locking groove 523. Then, the inner plate 522 can automatically move downward under the action of gravity and retract into the inner plate 521. The overall length of the rotating plate 52 becomes shorter, and the top plate 51 also moves downward to below the guide plate 44. Then, the rotating plate 52 contacts the horizontal plate 56 and rotates back. During the process of the top plate 51 rotating back to the initial position, it does not contact the guide plate 44.

[0047] Working principle: Place the steel wire to be processed into each of the storage boxes 43. When performing heat treatment such as annealing on the stainless steel wire, open the furnace door 11 and push the traveling trolley 31 into the heat treatment furnace 1 by manual or electric means. Push the traveling trolley 31 to the right. The traveling trolley 31 pushes the storage box 43 in the working position to move through the push plate 33 until the storage box 43 is separated from the hanging plate 42 and stops on the traveling trolley 31. Then, the traveling trolley 31 sends the storage box 43 containing the stainless steel wire in the working position into the heat treatment furnace 1. After closing the furnace door 11, start the heat treatment furnace 1 to perform heat treatment on the stainless steel wire. After the storage box 43 in the work station is removed, it becomes empty. The overall center of gravity of the turntable 41 changes and it rotates automatically until the empty hanging plate 42 rotates to the top. Then the next hanging plate 42 loaded with the storage box 43 rotates into the work station. After the heat treatment is completed, the furnace door 11 is opened and the traveling trolley 31 moves from the heat treatment furnace 1 to the left into the preheating chamber 2. After the traveling trolley 31 moves to the left, the driven plate 53 contacts the lever plate 55. The lever plate 55 presses the driven plate 53, causing the rotating plate 52 to start rotating. After the rotating plate 52 rotates, it drives the top plate 51 to move upward and sends the storage frame 43 into the guide plate 44. After the trolley 31 continues to move to the left, the driven plate 53 separates from the lever plate 55, and the horizontal plate 56 contacts the rotating plate 52. The horizontal plate 56 pushes the rotating plate 52 to rotate, and after rotating, the rotating plate 52 stops on the trolley 31. Then, the trolley 31 can pass under the storage frame 43 in the workstation until the trolley 31 moves to the initial position to the left. In this way, the function of automatic rotation and turning of the rotating plate 52 is realized during the movement of the trolley 31 after the heat treatment is completed.

[0048] During the heat treatment process, the equipment utilizes the heat emitted by the air-cooled stainless steel wire in the preheating chamber 2 to preheat the remaining stainless steel wires to be treated. This preheating treatment not only helps improve the quality of the steel wire and reduces the heating time required for subsequent heat treatment, thus improving production efficiency, but also enables the reuse of the heat in the heat-treated steel wire. The traveling trolley 31 automatically removes the storage frame 43 from the work station, and the rotation of the turntable 41, driven by the change in the center of gravity, causes another set of storage frames 43 to automatically move to the work station. With the movement of the traveling trolley 31 and the pusher 5, the heat-treated storage frames 43 are automatically placed on the turntable 41, thus enabling continuous cyclic use, high automation, and convenient operation.
