Technical Field

[0001] The utility model relates to the technical field of nut processing, in particular to a nut normalizing heat treatment tool. Background Art

[0002] Nut normalizing is to place the blank with nut shape made by metal powder compression molding in a placement frame and transfer it to the normalizing heat treatment device for high-temperature normalizing heating treatment. After the treatment, the distance between the metal powder of the nut becomes smaller and closer, which enables the nut processing to be completed.

[0003] The existing nut normalizing heat treatment tooling on the market currently requires that a nut-shaped blank made by metal powder compression molding be placed in a placement frame and conveyed to a normalizing heat treatment device for high-temperature normalizing heating treatment. After the treatment, the spacing between the metal powders of the nut becomes smaller and tighter, thereby completing the nut processing. However, after the existing normalizing treatment tooling conveys the placement frame filled with nut blanks into the normalizing device, some metal powder is likely to remain in the frame. If these powders are not cleared in time, they are likely to adhere to the nut blanks loaded next time, resulting in an uneven surface after the next batch of nuts are adhered and normalized. Utility Model Content

To achieve the above purpose, the utility model provides the following technical solutions: a nut normalizing heat treatment tool, including a heat treatment tool body, the inner wall of the heat treatment tool body is slidably connected to a transmission rack, and one end of the transmission rack is fixedly connected to a clapper for clapping a moving loading frame.

[0007] As an optional solution for a nut normalizing heat treatment tooling described in the utility model, wherein: the outer wall of the transmission roller is fixedly connected with a first transmission gear, the outer wall of the first transmission gear is meshingly connected with a transmission tooth chain, the inner wall of the transmission tooth chain is meshingly connected with a second transmission gear, and one end of the second transmission gear is rotatably connected to the inner wall of the heat treatment tooling body.

[0008] As an optional scheme for a nut normalizing heat treatment tooling described in the utility model, wherein: the other end of the second transmission gear is fixedly connected to a turntable, the outer wall of the turntable is fixedly connected to a second rotating horizontal axis, and the outer wall sliding sleeve of the second rotating horizontal axis is provided with a shift fork.

[0011] As an optional solution of a nut normalizing heat treatment tooling described in the utility model, wherein: the end of the fork is fixedly connected with a sector gear, and the sector gear is meshed with the transmission rack.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] In the utility model, the nut is being heat treated by starting the transmission motor body, which causes the transmission rack to move up and down reciprocatingly, which causes the transmission rack to slide up and down on the inner wall of the heat treatment tool body, while the clapper fixed at one end thereof continuously claps the mobile loading frame that has been unloaded and continuously passes above, thereby clapping it and causing the metal powder in the mobile loading frame to fall off, thereby preventing the metal powder from remaining in the mobile loading frame and causing the next batch of nut embryos to stick together and cause an uneven surface.

[0014] In the utility model, the nut is heat-treated. In the actual setting process, the two ends of the movable loading frame must be arranged in the inner wall of the limit groove and close to the inner wall of the limit groove. In this way, during the movement of the metal mesh crawler, both ends of the movable loading frame are on the inner wall of the limit groove, and will not be unbalanced to the left and right to cause flipping;

[0015] As the metal mesh track corresponding to the limit groove rotates to the lower side, the shape of the limit groove is gradually changed, and it can no longer support the two ends of the movable loading frame. At this time, the movable loading frame can be flipped along the first rotating horizontal axis to pour out the nuts that have been sintered. BRIEF DESCRIPTION OF THE DRAWINGS

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Embodiment 1

[0024] This embodiment is intended to promote the solution of the problem that after the existing normalizing tooling conveys the placement frame filled with nut embryos into the normalizing device, some metal powder is likely to remain in the frame. If these powders are not cleared in time, they are likely to adhere to the nut embryos loaded next time, resulting in uneven surfaces after the next batch of nuts are adhered. Please refer to Figure 1-Figure 5 A nut normalizing heat treatment tool comprises a heat treatment tool body 1, the inner wall of the heat treatment tool body 1 is slidably connected with a transmission rack 17, and one end of the transmission rack 17 is fixedly connected with a clapper 18 for clapping a moving object frame 7;

[0025] The outer wall of the heat treatment tool body 1 is installed with a transmission motor body 2, and the output end of the transmission motor body 2 is fixedly connected with a transmission roller shaft 3, one end of the transmission roller shaft 3 is rotatably connected with the inner wall of the heat treatment tool body 1, and the outer wall of the transmission roller shaft 3 is rotatably sleeved with a metal mesh crawler 4, and the metal mesh crawler 4 is set as a metal mesh belt, and two transmission roller shafts 3 are provided;

[0026] The outer wall of the transmission roller shaft 3 is fixedly connected with a first transmission gear 8, the outer wall of the first transmission gear 8 is meshedly connected with a transmission toothed chain 9, the inner wall of the transmission toothed chain 9 is meshedly connected with a second transmission gear 10, and one end of the second transmission gear 10 is rotatably connected with the inner wall of the heat treatment tooling body 1;

[0027] The other end of the second transmission gear 10 is fixedly connected to a rotating disk 11, the outer wall of the rotating disk 11 is fixedly connected to a second rotating horizontal axis 12, and the outer wall of the second rotating horizontal axis 12 is slidably sleeved with a shift fork 13;

[0028] The inner wall of the shift fork 13 is provided with a slide groove 14, and the inner wall of the slide groove 14 is slidably connected to the outer wall of the second rotation horizontal axis 12. The inner wall of the shift fork 13 is fixedly connected to the third rotation horizontal axis 15, and the shift fork 13 is rotatably connected to the inner wall of the heat treatment tooling body 1 through the third rotation horizontal axis 15;

[0029] The end of the shift fork 13 is fixedly connected with a sector gear 16 , and the sector gear 16 and the transmission rack 17 are meshed with each other.

[0030] In this embodiment: the existing nut normalizing heat treatment tooling on the market currently needs to place the blank with a nut shape made by metal powder die-casting in a placement frame and transfer it to the normalizing heat treatment device for high-temperature normalizing heating treatment. After the treatment, the spacing between the metal powders of the nut becomes smaller and closer, which facilitates the completion of the nut processing. However, after the existing normalizing treatment tooling conveys the placement frame filled with nut blanks into the normalizing device, some metal powders are likely to remain in the frame. If these powders are not cleared in time, they are likely to adhere to the nut blanks loaded next time, resulting in uneven surfaces of the next batch of nuts after normalizing due to adhesion;

[0031] In order to prevent the above situation from occurring, during processing, the nut embryos that need to be normalized and sintered are first neatly stacked in the mobile loading frame 7, and then the transmission motor body 2 is started to rotate its output end, and during the rotation, the first transmission gear 8 fixed on the output end is rotated together with it. During the rotation of the first transmission gear 8, the transmission tooth chain 9 on its outer sleeve is rotated together through the meshing relationship. When the transmission tooth chain 9 rotates, it rotates together with the second transmission gear 10 meshed with its inner wall. As the second transmission gear 10 rotates, a turntable 11 fixed at one end of the second transmission gear 10 rotates at a uniform speed. The rotation of the turntable 11 rotates the second rotating horizontal axis 12 of its outer wall at the same time, and since the second rotating horizontal axis 12 is located on the outer wall of the turntable 11, the second rotating horizontal axis 12 is located on the outer wall of the turntable 11. The movable horizontal axis 12 will move along a circular trajectory. During the circular movement of the second rotating horizontal axis 12, the fork 13 set on the outside will be constantly offset by force. In the process of offset, the fork 13 as a whole is forced to rotate slightly along the rotating connection between the third rotating horizontal axis 15 and the heat treatment tooling body 1. This slight rotation causes the fan-shaped gear 16 fixed at one end of the fork 13 to move along. During the movement, the transmission rack 17 is also moved through the meshing relationship. As the turntable 11 continues to rotate, the fork 13 will continuously deviate along a fixed trajectory, causing the fan-shaped gear 16 at one end of the fork 13 to continuously reciprocate to mesh with the transmission rack 17 upward or downward, so that the transmission rack 17 continuously reciprocates up and down.

[0032] The up and down reciprocating movement of the transmission rack 17 will cause the transmission rack 17 to slide up and down on the inner wall of the heat treatment tooling body 1, while the clapper 18 fixed at one end thereof will continuously clap the mobile loading frame 7 that has been unloaded and continuously passed above, thereby beating it, causing the metal powder in the mobile loading frame 7 to fall off, and preventing the metal powder from remaining in the mobile loading frame 7, which will cause the next batch of nut blanks to stick together and cause an uneven surface.

[0033] Embodiment 2

[0034] This embodiment is intended to promote the solution of the problem that in the first embodiment, a first rotating horizontal axis 6 is used to rotate the movable carrier frame 7 in the limiting groove 5, which will cause the movable carrier frame 7 to be unbalanced left and right during the movement of the metal mesh track 4, so that the movable carrier frame 7 is unbalanced left and right along the rotation connection between the first rotating horizontal axis 6 and the limiting groove 5. This embodiment is an improvement made on the basis of the first embodiment. For details, please refer to Figure 1-Figure 5 The outer wall of the metal mesh track 4 is provided with a limiting groove 5, and there are multiple limiting grooves 5. The inner wall of the limiting groove 5 is rotatably connected with a first rotating horizontal axis 6. The outer wall of the first rotating horizontal axis 6 is fixedly connected to a movable loading frame 7. The movable loading frame 7 is set as a U-shaped frame, and the movable loading frame 7 is tightly fitted with the inner wall of the limiting groove 5.

[0035] In this embodiment: In the first embodiment, a first rotating horizontal axis 6 is used to rotate the movable loading frame 7 in the limiting groove 5, which will cause the movable loading frame 7 to be unbalanced left and right during the movement of the movable loading frame 7 along the metal mesh track 4, so that the movable loading frame 7 is unbalanced left and right along the rotation connection with the limiting groove 5 with the first rotating horizontal axis 6;

[0036] Therefore, in the actual setting process, the two ends of the movable loading frame 7 must be arranged in the inner wall of the limiting groove 5 and close to the inner wall of the limiting groove 5, so that during the movement of the metal mesh crawler 4, both ends of the movable loading frame 7 are on the inner wall of the limiting groove 5, and will not be unbalanced to the left and right to cause flipping;

[0037] When the metal mesh track 4 moves the mobile loading frame 7 with the driving roller shaft 3 at the end, as the metal mesh track 4 corresponding to the limiting groove 5 rotates to the lower side, the shape of the limiting groove 5 is gradually changed, and it can no longer support the two ends of the mobile loading frame 7. At this time, the mobile loading frame 7 can be flipped along the first rotating horizontal axis 6, the nuts that have been sintered by normalizing are poured out, and rotate to the lower side of the metal mesh track 4 to move.

Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0039] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
