[0033] In order to enable those skilled in the art to better understand the technical solution of the present invention, Figure 1 -Attached Fig. 9 , the present invention is further introduced in detail.

[0034] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "degree", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0035] An embodiment of the present invention provides an intelligent heat treatment system for rare metal products, including a quenching barrel 1 and a conveying component. The quenching barrel 1 is filled with quenching liquid 3. The conveying component inserts the heated metal part 4 into the central area of ​​the quenching barrel 1. A diffusion component 2 is installed at the center of the quenching barrel 1. The diffusion component 2 is used to drive impurities in the quenching liquid 3 around the metal part 4 away from the metal part 4.

[0036] Specifically, before the quenching of the metal part 4 begins, the diffusion component 2 located at the center of the quenching barrel 1 starts to work. In this embodiment, the diffusion component 2 may include a vibration motor, which generates high-frequency vibration at the center of the quenching barrel 1, driving the quenching liquid 3 in the quenching barrel 1 to diffuse from the center to the surroundings. With the movement of the quenching liquid 3, and under the action of gravity, the impurities in the quenching liquid 3 follow the quenching liquid 3 and diffuse from the center to the bottom of the surrounding edges, especially sinking to the bottom area, reducing the impurity content at the center of the quenching barrel 1 (that is, the axis position of the quenching barrel 1). Subsequently, the heated metal part 4 is inserted into the quenching barrel 1 manually or automatically, and the heated metal part 4 contacts the quenching liquid 3 in the quenching barrel 1 to complete the quenching treatment of the metal part 4. In order to reduce the influence of the vibration motor on quenching, it is preferred to connect the vibration motor to the center of the bottom of the quenching barrel 1 through a vibration reduction mechanism such as a spring assembly. The sealing insulation of the vibration motor used underwater is a prior art and will not be repeated.

[0037] It should be noted that, in this embodiment, the vibration motor is a prior art, and the submersible motor is also a prior art. The vibration motor only needs to be well insulated and sealed, and no further details will be given.

[0038] Among them, when the vibration motor serving as the diffusion component 2 located at the center of the quenching barrel 1 vibrates, the quenching liquid 3 in the center of the quenching barrel 1 moves from the middle to the surroundings. When the quenching liquid 3 moving outward contacts the inner wall of the quenching barrel 1, the quenching liquid 3 flows back under the action of the inner wall of the quenching barrel 1, that is, the quenching liquid 3 moves toward the direction of the metal part 4 after contacting the inner wall of the quenching barrel 1. At this time, with the reflux of the quenching liquid 3, the refluxed quenching liquid 3 contacts the metal part 4 with impurities again, affecting the quenching effect of the metal part 4. In order to prevent the refluxed quenching liquid 3 from contacting the metal part 4 with impurities again, in another embodiment of the present invention, the diffusion component 2 includes a placement sleeve 51, and the placement sleeve 51 is vertically placed in the quenching barrel. 1, the placement sleeve 51 includes an inner cylinder 511 and an outer cylinder 512 arranged coaxially, the outer cylinder 512 is fixedly installed in the quenching barrel 1 through a connecting piece 52, the inner cylinder 511 and the outer cylinder 512 are rotatably arranged, and the inner cylinder 511 and the outer cylinder 512 are connected by a torsion spring, such as an annular receiving groove is arranged on the outer wall of the bottom of the inner cylinder 511, a torsion spring is arranged in the receiving groove, and two legs of the torsion spring are respectively fixed to the inner cylinder 511 and the outer cylinder 512 (not shown in the figure), and the side walls of the inner cylinder 511 and the outer cylinder 512 are both provided with filtering holes 53. In a preferred embodiment, in the initial state, the filtering holes 53 on the inner cylinder 511 and the outer cylinder 512 are arranged at intervals, and at this time, the quenching liquid 3 in the placement sleeve 51 cannot pass through the inner cylinder 511. The filter hole 53 on the outer cylinder 512 enters into the interior of the placement sleeve 51, and the bottom of the inner cylinder 511 is higher than the bottom of the outer cylinder 512. A plurality of drainage notches 55 are opened at the bottom of the outer cylinder 512. The plurality of drainage notches 55 are arranged at intervals along the circumference of the outer cylinder 512. A driving part 54 is also arranged in the placement sleeve 51. The driving part 54 includes a linear telescopic rod 541. A water pusher plate 542 is fixedly installed on the telescopic section of the linear telescopic rod 541. It should be noted that the linear telescopic rod 541 is tightly attached to the inner wall of the inner cylinder 511, so that when the metal part 4 is placed inside the inner cylinder 511, the linear telescopic rod 541 will not hinder the placement of the metal part 4 and affect the normal quenching of the metal part 4. The shape of the water pusher plate 542 is consistent with that of the inner cylinder. The inner diameter shape of 511 is consistent, and a first wedge block group 543 is fixedly installed on the lower plate surface of the water pushing plate 542, and a second wedge block group 544 is fixedly installed on the lower end of the inner cylinder 511. The first wedge block group 543 cooperates with the second wedge block group 544 to drive the inner cylinder 511 to rotate around its own axis, thereby realizing the opening and closing of the filter holes 53 on the inner cylinder 511 and the outer cylinder 512. It should be noted that the first wedge block group 543 and the second wedge block group 544 are both composed of a plurality of wedge blocks. The plurality of wedge blocks constituting the first wedge block group 543 are installed on the bottom surface of the water pushing plate 542 at intervals along the circumference of the water pushing plate 542, and the plurality of wedge blocks constituting the second wedge block group 544 are installed on the bottom end of the inner wall of the inner cylinder 511 at intervals along the circumference of the inner cylinder 511.

[0039] Specifically, before the metal part 4 is placed inside the quenching barrel 1 for quenching treatment, the linear telescopic rod 541 begins to extend, and the linear telescopic rod 541 moves toward the bottom of the quenching barrel 1 along the vertical direction with the water pusher plate 542. In the preferred embodiment, in the initial state, the filter holes 53 on the inner cylinder 511 and the outer cylinder 512 are arranged at intervals, that is, the filter holes 53 on the inner cylinder 511 and the filter holes 53 on the outer cylinder 512 are not aligned, and the quenching liquid 3 inside the inner cylinder 511 cannot pass through the filter holes 53 on the inner cylinder 511 and the outer cylinder 512 into the interval between the outer cylinder 512 and the quenching barrel 1, and because The cross-sectional shape of the water push plate 542 is consistent with the inner diameter shape of the inner cylinder 511, and then as the water push plate 542 moves downward, the water push plate 542 pushes the quenching liquid 3 inside the inner cylinder 511 to flow out from the drainage gap 55 at the bottom end of the outer cylinder 512. At this time, there is no quenching liquid 3 inside the inner cylinder 511 temporarily. Then, as the water push plate 542 continues to move downward, the first wedge block group 543 at the bottom of the water push plate 542 and the second wedge block group 544 at the bottom of the inner cylinder 511 squeeze each other. At this time, the inner cylinder 511 rotates with its own axis as the center of the circle. In this process, the torsion spring is deformed to accumulate elastic potential energy. The filter holes 53 on the outer cylinder 511 are aligned with the filter holes 53 on the outer cylinder 512. At this time, the quenching liquid 3 located outside the outer cylinder 512 flows into the inner cylinder 511 through the filter holes 53 on the outer cylinder 512 and the inner cylinder 511. Under the filtering effect of the filter holes 53, the impurities in the quenching liquid 3 are retained outside the outer cylinder 512, thereby preventing the impurities in the quenching liquid 3 from affecting the cooling performance and heat transfer performance of the quenching liquid 3 when the metal part 4 enters the quenching liquid 3, resulting in poor quenching effect during subsequent quenching treatment, making the hardness, strength and other properties of the metal parts not up to standard, affecting the quenching of the quenched metal The quenching effect is achieved, and impurities are prevented from being attached to the surface of the metal part 4, which reduces the adhesion and quality of the surface coating and affects the subsequent surface treatment or coating process. After the quenching of the metal part 4 is completed, the metal part 4 is pulled out of the quenching barrel 1 manually or automatically, and the linear telescopic rod 541 moves the water push plate 542 upward, and the first wedge block group 543 and the second wedge block group 544 on the water push plate 542 move away from each other. At this time, the torsion spring releases the accumulated elastic potential energy, driving the inner cylinder 511 to rotate in the opposite direction, so that the filter holes 53 on the inner cylinder 511 and the outer cylinder 512 return to the state of being spaced apart from each other in the initial state.

[0040] Obviously, in an optional solution, the filter holes 53 on the inner cylinder 511 and the outer cylinder 512 may always be opposite to each other. In this case, the inner cylinder 511 does not need to rotate, nor does it need the first wedge block group 543 and the second wedge block group 544. However, during the whole process, driven by the flow force of the water flow, some impurities may adhere to the inner wall of the inner cylinder 511 and get stuck in the gap between the water pusher plate 542 and the inner cylinder 511, which not only blocks the filter holes 53, but also affects the operation of the water pusher plate 542. Slower downward movement of the water pusher plate 542 can alleviate this problem. Based on actual needs, technical personnel in this field can choose to quickly move the water pusher plate 542 downward to empty the water flow or slowly move the water pusher plate 542 downward without emptying the water flow.

[0041] It should also be noted that in the structure requiring the first wedge block group 543 and the second wedge block group 544, after a long period of use, the impurities generated by quenching the quenching liquid 3 will gather at the bottom of the quenching barrel 1. Then, when large pieces of metal impurities fall onto the surface of any wedge block on the second wedge block group 544, the large pieces of metal impurities will block the wedge fit between the first wedge block group 543 and the second wedge block group 544, affecting the normal rotation of the inner cylinder 511. In this regard, in another embodiment of the present invention, the wedge blocks constituting the second wedge block group 544 are slidably connected to the inner cylinder 511, wherein a plurality of horizontally arranged slide grooves 6 are provided on the side wall of the inner cylinder 511, and the plurality of slide grooves 6 are arranged at intervals along the circumference of the inner cylinder 511, and the plurality of slide grooves 6 are connected to the plurality of slide grooves 6. The wedge blocks constituting the second wedge block group 544 correspond to each other one by one, and a sliding block 61 is slidably installed in the slide groove 6. The sliding block 61 is connected to the corresponding slide groove 6 by a connecting spring 62. The sliding block 61 is located on the side wall inside the inner cylinder 511 and is installed with the corresponding wedge block constituting the second wedge block group 544. It should be noted that, in this embodiment, the deformation limit of a single connecting spring 62 is greater than the pressure exerted on a single wedge block constituting the second wedge block group 544 when the inner cylinder 511 rotates, that is, when the connecting spring 62 is deformed and moves with the sliding block 61 along the groove direction of the slide groove 6, the pressure exerted on the corresponding wedge block constituting the second wedge block group 544 needs to be greater than the pressure exerted on the single wedge block constituting the second wedge block group 544 when the inner cylinder 511 rotates.

[0042] Specifically, as impurities precipitate, when large pieces of metal impurities fall onto the surface of any wedge block on the second wedge block group 544 (it should be noted that the metal impurities at this time have a certain volume, such as metal sheets or metal blocks, etc. In the present embodiment, the metal impurities are metal sheets), the large pieces of metal impurities will block the wedge cooperation between the first wedge block group 543 and the second wedge block group 544. At this time, the height of the wedge blocks constituting the second wedge block group 544 with metal impurities on the surface will increase (due to the presence of metal impurities on the surface), and then the wedge blocks constituting the second wedge block group 544 with metal impurities on the surface will first be squeezed against the corresponding wedge blocks constituting the first wedge block group 543. When the wedge blocks constituting the second wedge block group 544 with metal impurities on the surface are squeezed against the corresponding wedge blocks constituting the first wedge block group 543, the wedge blocks constituting the second wedge block group 544 with metal impurities on the surface will be subjected to the full pressure of the first wedge block group 543 and the water pusher plate 542. The wedge blocks of the second wedge block group 544 with metal impurities on the surface are subjected to a pressure greater than the pressure on a single wedge block of the second wedge block group 544 when the inner cylinder 511 rotates, and the corresponding connecting spring 62 is squeezed and deformed to shrink, and the slider 61 and the wedge blocks of the second wedge block group 544 with metal impurities on the surface slide synchronously along the groove of the slide groove 6, avoiding the corresponding wedge blocks of the first wedge block group 543, and then as the first wedge block group 543 continues to move downward, the remaining wedge blocks of the second wedge block group 544 without metal impurities on the surface are squeezed by the corresponding wedge blocks of the first wedge block group 543, driving the inner cylinder 511 to rotate with its own axis as the center, so that the filter holes 53 on the inner cylinder 511 and the filter holes 53 on the outer cylinder 512 are aligned with each other. At this time, the quenching liquid 3 outside the outer cylinder 512 enters the inner cylinder 511 along the connected filter holes 53, completing the filling process of the quenching liquid 3 inside the inner cylinder 511.

[0043] Among them, after the first wedge block group 543 and the second wedge block group 544 are squeezed, the wedge blocks constituting the second wedge block group 544 slide along the groove direction of the slide groove 6. At this time, the metal impurities on the wedge blocks constituting the second wedge block group 544 will not necessarily be separated from the wedge blocks constituting the second wedge block group 544 under the squeezing of the first wedge block group 543 and the second wedge block group 544, that is, the metal impurities still exist on the surface of the wedge blocks constituting the second wedge block group 544. When the metal part 4 is subsequently quenched, the metal impurities will still affect the normal cooperation between the wedge blocks constituting the second wedge block group 544 and the wedge blocks constituting the first wedge block group 543. In the long run, if the wedge blocks constituting the second wedge block group 544 When there are metal impurities on the surfaces of the wedge blocks, as the first wedge block group 543 moves downward, the wedge blocks constituting the second wedge block group 544 all slide along the corresponding groove of the slide groove 6. At this time, the inner cylinder 511 cannot be driven to rotate with its own axis as the center, that is, the filter holes 53 on the inner cylinder 511 and the outer cylinder 512 cannot be aligned, so that the filling process of the clean quenching liquid 3 inside the inner cylinder 511 cannot be achieved. In a further scheme of another embodiment of the present invention, the wedge blocks constituting the second wedge block group 544 are rotatably connected to the slider 61. For example, an adjusting shaft is provided on the side wall of the wedge blocks constituting the second wedge block group 544, and the adjusting shaft is arranged horizontally. The adjusting shaft is rotatably connected to the slider 61 through an adjusting torsion spring (the adjusting torsion spring (not shown in the figure), a plurality of one-way parts 7 are arranged on the inner wall of the inner cylinder 511, and the plurality of one-way parts 7 correspond to the plurality of slide grooves 6 one by one, and the one-way part 7 is located above the slide grooves 6 and in the sliding direction of the wedge blocks constituting the second wedge block group 544, that is, the wedge blocks constituting the second wedge block group 544 will contact the one-way part 7 when sliding along the slide grooves 6, wherein the one-way part 7 is used to drive the wedge blocks corresponding to the second wedge block group 544 to deflect toward the central axis direction of the inner cylinder 511, wherein the one-way part 7 includes a avoidance notch 71 provided on the inner wall of the inner cylinder 511, and a vertical rotating shaft 72 is connected to the avoidance notch 71 through a ratchet pawl mechanism (the one-way rotation of the ratchet pawl mechanism is a prior art and will not be described in detail here) , a rotating gear 73 is fixedly mounted on the rotating shaft 72, and one side of the rotating gear 73 extends into the inner tube 511, wherein a plurality of vertical grooves are provided on the surface of the wedge block constituting the second wedge block group 544 close to the rotating gear 73 (that is, the surface of the wedge block constituting the second wedge block group 544 close to the rotating gear 73 is in the shape of a rack that matches the rotating gear 73, and is described as the rack surface of the wedge block in the following description). When the wedge block constituting the second wedge block group 544 slides in the slide groove 6 along the counterclockwise direction following the slider 61, the rack surface of the wedge block constituting the second wedge block group 544 meshes with the rotating gear 73, the rotating gear 73 rotates, and the wedge block constituting the second wedge block group 544 passes through the rotating gear 73 normally;When the wedge blocks constituting the second wedge block group 544 slide in the slide groove 6 along the clockwise direction following the slider 61, the rotating gear 73 is connected to the ratchet pawl mechanism structure, and thus the rotating gear 73 cannot rotate at this time, so the wedge blocks constituting the second wedge block group 544 will be blocked by the rotating gear 73 when sliding in the clockwise direction, and the elastic force of the connecting spring is relatively large. Due to the inclined surface effect of the toothed structure and the rotational connection between the wedge blocks constituting the second wedge block group 544 and the slider 61, the wedge blocks constituting the second wedge block group 544 are forced to deflect toward the axial direction of the inner cylinder 511 under the traction of the connecting spring 62. ;

[0044] Specifically, when there are metal impurities on the surface of the wedge blocks constituting the second wedge block group 544, as the first wedge block group 543 moves downward and is squeezed, the wedge blocks constituting the second wedge block group 544 with metal impurities on the surface follow the slider 61 to slide along the groove 6, and the connecting spring 62 contracts to accumulate elastic potential energy. The wedge blocks constituting the second wedge block group 544 contact the rotating gear 73 during the sliding process. When the wedge blocks constituting the second wedge block group 544 slide in the slide groove 6 in the counterclockwise direction following the slider 61, the wedge blocks constituting the second wedge block group 544 The rack surface of the wedge block 544 meshes with the rotating gear 73, and the rotating gear 73 rotates, so that the wedge blocks constituting the second wedge block group 544 pass through the position of the rotating gear 73 normally, and with the cooperation of the first wedge block group 543 and the second wedge block group 544, the inner cylinder 511 is filled with the filtered quenching liquid 3, and then the metal piece 4 is placed into the inner cylinder 511 manually or automatically to contact the quenching liquid 3 for quenching treatment. After the quenching treatment of the metal piece 4 is completed, the first wedge block group 543 is separated from the second wedge block group 544. At this time, the connecting spring 62 releases the accumulated elastic potential energy, and the connecting spring 62 pushes the slider 61 to slide along the clockwise direction with the wedge-shaped block constituting the second wedge block group 544 following the slider 61 in the sliding groove 6. Because the rotating gear 73 is connected to the ratchet pawl mechanism structure, the rotating gear 73 cannot rotate at this time, so that the wedge-shaped block constituting the second wedge block group 544 will be blocked by the rotating gear 73 when sliding in the clockwise direction. However, because the wedge-shaped block constituting the second wedge block group 544 is rotationally connected to the slider 61, the connecting spring 6 2, the wedge blocks constituting the second wedge block group 544 deflect toward the axial direction of the inner cylinder 511 with the axis of the adjusting shaft as the center. During the deflection process, the wedge blocks constituting the second wedge block group 544 deflect synchronously with the metal impurities. After the deflection, the metal impurities sink to the bottom of the inner cylinder 511 due to gravity, that is, the metal impurities are separated from the surface of the wedge blocks constituting the second wedge block group 544. At this time, there are no more metal impurities in the wedge blocks constituting the second wedge block group 544, thereby ensuring the long-term use of the wedge blocks constituting the second wedge block group 544.

[0045] In order to prevent the drainage gap 55 at the bottom of the inner cylinder 511 from being blocked, a cleaning rod 74 is further installed on the surface of the wedge block constituting the second wedge block group 544. One end of the cleaning rod 74 is hinged to the surface of the wedge block constituting the second wedge block group 544, and the other end of the cleaning rod 74 passes through the drainage gap 55 and extends into between the outer cylinder 512 and the quenching barrel 1. When the wedge blocks constituting the second wedge block group 544 slide along the groove direction of the slide groove 6, the wedge blocks constituting the second wedge block group 544 slide synchronously at the drainage gap 55 with the cleaning rod 74. The cleaning rod 74 reciprocates at the drainage gap 55, and the part of the cleaning rod 74 passing through the drainage gap 55 can push the metal waste blocking the drainage gap 55 to the two sides of the drainage gap 55, thereby ensuring the unobstructed flow of the drainage gap 55 and avoiding the blockage of the drainage gap 55.

It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
