Description

Technical Field

[0001] The present application relates to the technical field of heat treatment related equipment, and in particular to a heat treatment tray for ring-shaped parts. Background Art

[0002] During the heat treatment of ring parts, parameters such as heating temperature, holding time and cooling rate need to be strictly controlled to ensure the expected process effect. At the same time, factors such as material type, composition and original organizational state need to be considered to formulate a suitable heat treatment process plan.

[0003] However, the heat treatment of ring parts also faces some technical challenges. In conventional heat treatment, the ring parts need to be placed on a tray, and then placed on a rack. In the process of placing the tray on the rack, the ring parts are prone to displacement, so that the ring parts are easy to slide to the area with poor heating effect, resulting in uneven heating of the ring parts during the heat treatment process, which is easy to cause defects such as deformation and cracking, affecting the quality and performance of the product. Utility Model Content

[0004] In order to prevent the ring-shaped member from being deformed as much as possible during heat treatment, the present application provides a heat treatment tray for the ring-shaped member.

[0005] The heat treatment tray for ring-shaped parts provided in the present application adopts the following technical solution:

[0006] A heat treatment tray for ring-shaped parts comprises a base plate, on which a plurality of honeycomb-shaped through holes are arranged; a plurality of positioning protrusions are arranged on the base plate, and the plurality of positioning protrusions are arranged at intervals at the connection points of adjacent through holes, and a plurality of ring-shaped parts can be placed between the plurality of positioning protrusions.

[0007] By adopting the above technical solution, through holes are set up to facilitate heat conduction and reduce the weight of the tray; and a plurality of positioning protrusions are used to limit the position of the ring-shaped parts so that the ring-shaped parts will not be displaced as much as possible during the processing, thereby making the heating of the plurality of ring-shaped parts relatively uniform, and further making the ring-shaped parts less likely to be deformed during the heat treatment.

[0008] Preferably, a plurality of support rods are further provided on the base plate, the support rods are located on the same side of the base plate where the positioning protrusions are provided, and the plurality of support rods are provided at the connection between adjacent vacant through holes.

[0009] By adopting the above technical solution, the annular member with a relatively small inner diameter can be directly sleeved on the support rod by utilizing the support rod to achieve positioning, thereby expanding the scope of application of the present application.

[0010] Preferably, one end of the support rod away from the base plate is configured as a reduced diameter end.

[0011] By adopting the above technical solution and providing a reduced diameter end, more annular members with different inner diameters can be clamped on the support rod to achieve positioning, thereby further expanding the scope of application of the present application.

[0012] Preferably, a plurality of support protrusions are further provided on the inner wall of the through hole, and the support protrusions are arranged along the circumferential direction of the inner wall of the through hole; one end of the support protrusion is connected to the inner wall of the through hole, and the other end of the support protrusion faces the center of the through hole.

[0013] By adopting the above technical solution and providing support protrusions, objects with other outer diameters can be placed on multiple support protrusions, and position limiting is achieved through the inner wall of the through hole.

[0014] Preferably, the plurality of supporting protrusions are arranged on a side of the substrate away from the positioning protrusion.

[0015] By adopting the above technical solution, the inner wall of the through hole can be fully utilized to limit the annular member placed on the supporting protrusion, thereby preventing the annular member from falling out of the through hole as much as possible.

[0016] Preferably, the plurality of support protrusions are evenly arranged along the circumferential direction of the inner wall of the through hole.

[0017] By adopting the above technical solution, the annular member can be stably supported.

[0018] Preferably, a positioning hole is provided on the base plate corresponding to the positioning column of the material cart, and the positioning column is slidably inserted into the positioning hole.

[0019] By adopting the above technical solution, multiple pallets can be stacked layer by layer on the material cart through the positioning holes and positioning columns that slide together.

[0020] Preferably, a height of the support rod based on the base plate is greater than a height of the annular member based on the base plate.

[0021] By adopting the above technical solution, the ring-shaped parts placed on the lower tray can be prevented from being squeezed by the upper tray as much as possible.

[0022] In summary, the present application includes at least one of the following beneficial technical effects:

[0023] 1. Use multiple positioning protrusions to limit the movement range of the ring on the tray, so as to avoid the ring during processing, and thus make the ring evenly heated as much as possible;

[0024] 2. By using the support rods and the support protrusions, other annular parts of different sizes can achieve effective displacement limitation, thereby improving the scope of application of the present application. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The following is combined with Figure 1-3 This application is described in further detail.

[0030] The embodiment of the present application discloses a heat treatment tray for ring-shaped parts.

[0031] Reference Figure 1 A heat treatment tray for an annular component includes a substrate 1, on which a plurality of through holes 11 are evenly arranged. The substrate 1 has a plurality of through holes 11 evenly distributed. A plurality of support rods 2 and a plurality of positioning protrusions 3 are arranged on the same side of the substrate 1, and a plurality of positioning protrusions 3 close to one support rod 2 are arranged close to the support rod 2 along the circumferential direction. Taking one of the support rods 2 and the plurality of positioning protrusions 3 close to the support rod 2 as an example, when the annular component needs to be placed on the tray, the annular component is sleeved on the outer side of the support rod 2, and the outer wall of the annular component abuts against the inner side of the plurality of positioning protrusions 3 close to the support rod 2, so that the annular component can be fixed on the tray.

[0032] The through holes 11 are in a hexagonal honeycomb shape, and a plurality of through holes 11 are distributed in a honeycomb network shape on the substrate 1. A plurality of support rods 2 and a plurality of positioning protrusions 3 are integrally formed on the substrate 1 to improve the installation strength of the support rods 2 and the positioning protrusions 3. A plurality of support rods 2 are arranged at intervals at the connection between adjacent through holes 11, and the positioning protrusions 3 are arranged to fill in the connection between the remaining adjacent through holes 11, so that while the distance between adjacent positioning protrusions 3 and support rods 2 is the same, more annular parts can be placed as much as possible using the existing substrate 1 area, saving costs.

[0033] The support rod 2 is in the shape of a triangular prism as a whole, and the length direction of the support rod 2 is perpendicular to the surface of the substrate 1. The side of the support rod 2 smoothly transitions with the side of the through hole 11, and the side of the support rod 2 near the corner of the through hole 11 is integrally formed with a depression that smoothly transitions with the corner. The positioning protrusion 3 and the support rod 2 have roughly the same shape, except that the height of the positioning protrusion 3 based on the substrate 1 is less than the height of the support rod 2 based on the substrate 1.

[0034] Preferably, the end of the support rod 2 away from the base plate 1 is set as a reduced diameter end, so that a ring member with a smaller inner diameter can be placed on the support rod 2, thereby expanding the application scope of this embodiment.

[0035] In order to further expand the scope of use of this embodiment, a plurality of support protrusions 4 are integrally formed on the side of the substrate 1 away from the support rod 2, and the plurality of support protrusions 4 are evenly arranged on the inner wall of each through hole 11 along the circumferential direction of the through hole 11. The support protrusion 4 is in the shape of a rectangular plate, and the length direction of the support protrusion 4 is perpendicular to the inner wall of the through hole 11 where the support protrusion 4 is located. Rings with different outer diameters can be placed in the through hole 11, and the rings can be placed on the substrate 1 through the support protrusion 4.

[0036] Reference Figure 3 , a pallet is usually used in conjunction with a material cart, so that multiple annular parts can be easily transported. A plurality of positioning posts 5 are provided on the material cart. Four are used as an example for explanation. The substrate 1 is provided with positioning holes 12 corresponding to each positioning post 5. The positioning posts 5 are slidably penetrated in the positioning holes 12. In this embodiment, the positioning holes 12 are provided at the four corners of the substrate 1. When a pallet is covered with annular parts, the pallet is placed on the pallet through the positioning holes 12 and the positioning posts 5 that are slidably connected, and the remaining pallets are stacked on the pallet layer by layer. The height of the support rod 2 based on the substrate 1 is greater than the height of the annular parts based on the substrate 1. The support rod 2 is used to enable the lower pallet to support the upper pallet, so as to prevent the annular parts placed on the lower pallet from being squeezed by the upper pallet.

[0037] The implementation principle of a heat treatment tray for ring-shaped parts in the embodiment of the present application is as follows: by setting a positioning protrusion 3, the movement range of the ring-shaped parts on the tray can be limited; and by setting a support rod 2 and a support protrusion 4, the ring-shaped parts of other different sizes can achieve effective displacement limitation, thereby preventing the ring-shaped parts from being deformed during the processing, and thus making the ring-shaped parts as evenly heated as possible.

[0038] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
