Description

Technical Field

[0001] The utility model relates to the technical field of forging and forming, in particular to a quenching device for heat treatment of annular forgings. Background Art

[0002] Ring forgings used in the aerospace field are mostly high-temperature alloys. High-temperature alloys need to be quenched during heat treatment. The quenching medium is generally oil or water. During the quenching process, equipment is required to send the rack and the ring forgings on the rack into the cooling tank. In the cooling tank, the cooling medium is stirred to ensure full and uniform contact with the ring forgings.

[0003] The existing material racks for loading ring forgings do not have corresponding limiting structures designed for the ring forgings. There is a risk of the material racks tipping over during transportation and quenching, and the tipping and falling of the ring forgings will also affect the normal production process and reduce production efficiency.

[0004] Therefore, a technical solution is currently needed to solve the technical problem that there is no structure for limiting the ring forgings on the ring forging quenching rack, and the ring forgings are prone to tipping and falling during the transportation and quenching process. Utility Model Content

[0005] The purpose of the invention of the utility model is to provide a quenching device for heat treatment of ring forgings to solve the technical problem that there is no structure for limiting the position of the ring forgings on the ring forging quenching rack, and the ring forgings are prone to tipping and falling during the transportation and quenching process.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] A quenching device for heat treatment of annular forgings includes a material rack with a plurality of leak holes evenly arranged on the material rack, and also includes a plurality of limiting mechanisms. The limiting mechanisms include a column connected to the material rack, and the column is connected to a limiting ring, and the limiting ring is used to abut against the inner wall of the annular forging.

[0008] The utility model discloses a quenching device for heat treatment of annular forgings. When in use, the annular forgings are placed at positions corresponding to columns on a material rack, the columns extend into the interior of the annular forgings, and limiting rings on the tops of the columns abut against the inner walls of the annular forgings, thereby limiting the annular forgings and making the position of the annular forgings on the material rack more stable, so as to reduce the annular forgings from tipping over or falling off during transportation and quenching.

[0009] As a preferred solution of the utility model, the inner wall of the limit ring is connected with a plurality of connecting rods, the connecting rods are connected to the pillars, and the plurality of connecting rods are arranged around the pillars. The connection between the limit ring and the pillars is realized, and at the same time, the connecting rods will not form a seal on the inside of the limit ring, so that the cooling oil can flow normally inside the annular forging, ensuring that the cooling oil can quickly and fully contact the annular forging.

[0010] As a preferred solution of the utility model, the column can be extended or shortened. Since the inner wall of the annular forging is mostly conical, the inner diameters of different annular forgings at the same height are different. By extending or shortening the column, the height of the limit ring on the column can be adjusted, so that the limit ring can limit the position of annular forgings of different specifications.

[0011] As a preferred solution of the utility model, the column includes a column and a sleeve, the column is connected to the material rack, the sleeve is connected to the limit ring, and the sleeve is threadedly connected to the column. By rotating the sleeve on the column, the relative position of the sleeve and the column can be adjusted, thereby adjusting the length of the entire column, and the sleeve can be removed from the column. When the specifications of the loaded annular forgings vary greatly, the sleeve and the limit ring on the sleeve can be replaced so that the limit ring can match more specifications of annular forgings, thereby increasing the application range of the device to annular forgings.

[0012] As a preferred solution of the utility model, a plurality of guide grooves are arranged around each leakage hole, and the guide grooves are connected with the leakage hole, so that the cooling oil on the material rack can enter the guide grooves, and then flow to the leakage hole through the guide grooves, thereby improving the efficiency of the cooling oil flowing back to the oil tank.

[0013] As a preferred solution of the utility model, the guide groove is arranged in an inclined shape, and the lower end of the guide groove is connected to the leakage hole, so that the cooling oil in the guide groove can flow to the leakage hole more easily, and then the cooling oil can flow back to the oil tank more quickly when the rack is lifted in the oil tank.

[0014] As a preferred solution of the utility model, the limit ring is set as a circular ring structure with a circular cross section, so that the limit ring and the inner wall of the ring forging are in line contact, which reduces the blocking effect of the limit ring on the cooling oil, so that the cooling oil and the ring forging are in full contact, and the quenching effect of the ring forging is improved.

[0015] As a preferred solution of the utility model, a plurality of the limiting mechanisms are arranged in a rectangular array on the material rack, so that more limiting mechanisms can be arranged on the material rack of the same area, thereby improving the loading efficiency of the annular forgings on the material rack, and further improving the transportation and quenching efficiency of the annular forgings.

[0016] As a preferred solution of the utility model, the material rack is provided with an annular limiting edge, and the annular limiting edge is arranged around the edge of the material rack. By arranging an annular limiting edge with a height of 5mm-10mm on the edge of the material rack, the cooling oil on the material rack is blocked to reduce the spillage of the cooling oil during the transportation of the material rack and the annular forging.

[0017] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0018] The present application arranges columns on the material rack, and abuts the inner wall of the annular forging through a limiting ring on the column, so that the position of the annular forging on the material rack is more stable, reducing the risk of the annular forging tipping over or falling during transportation and quenching.

[0024] The utility model is described in detail below in conjunction with the accompanying drawings.

[0025] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0026] Example 1

[0027] like Figure 1 , Figure 2 and Figure 3As shown, the present embodiment is a quenching device for heat treatment of annular forgings, comprising a material rack 1, on which a plurality of leakage holes 11 are evenly arranged, and also comprising a plurality of limiting mechanisms, which are arranged in a circular array on the material rack 1, and the limiting mechanisms include a column 2, which is connected to the material rack 1, and the column 2 is connected to a limiting ring 3, and the limiting ring 3 is used to abut against the inner wall of the annular forging.

[0028] When in use, the annular forging is placed on the material rack 1 at a position corresponding to the column 2, the column 2 extends into the interior of the annular forging, and the limiting ring 3 on the top of the column 2 abuts against the inner wall of the annular forging, thereby limiting the annular forging and making the position of the annular forging on the material rack 1 more stable, so as to reduce the tipping or falling of the annular forging during transportation and quenching.

[0029] Specifically, a plurality of connecting rods 4 are arranged around the top of the column 2. One end of the connecting rod 4 is connected to the column 2, and the other end is connected to the inner wall of the limiting ring 3. The limiting ring 3 is an annular structural member with a circular cross section.

[0030] Furthermore, the material rack 1 is provided with an annular limiting edge 13, and the annular limiting edge 13 is arranged around the edge of the material rack 1. By setting the annular limiting edge 13 with a height of 5mm-10mm on the edge of the material rack 1, a blocking effect is played on the cooling oil on the material rack 1, so as to reduce the spillage of cooling oil during the transportation of the material rack 1 and the annular forgings.

[0031] Example 2

[0032] like Figure 1 , Figure 3 and Figure 4 As shown, in this embodiment, the difference from Embodiment 1 is that the column 2 can be extended or shortened.

[0033] In this embodiment, since the inner wall of the annular forging is mostly conical, the inner diameters of different annular forgings at the same height are different. By extending or shortening the column 2, the height of the limit ring 3 on the column 2 can be adjusted, so that the limit ring 3 can limit the annular forgings of different specifications.

[0034] Specifically, the column 2 includes a column 21 and a sleeve 22, the column 21 is connected to the material rack 1, the sleeve 22 is connected to the limit ring 3, the sleeve 22 is threadedly connected to the column 2, and the relative position of the sleeve 22 and the column 2 can be adjusted by rotating the sleeve 22 on the column 2, thereby adjusting the length of the entire column 2, and the sleeve 22 can be removed from the column 21. When the specifications of the loaded annular forgings vary greatly, the sleeve 22 and the limit ring 3 on the sleeve 22 can be replaced so that the limit ring 3 can match more specifications of annular forgings, thereby increasing the application range of the device to annular forgings.

[0035] Example 3

[0036] like Figure 1 and Figure 2 As shown, the difference between this embodiment and embodiment 1 is that a plurality of guide grooves 12 are arranged around each leakage hole 11 , and the guide grooves 12 are connected to the leakage hole 11 .

[0037] In this embodiment, the cooling oil on the material rack 1 can enter the guide groove 12, and then flow to the leakage hole 11 through the guide groove 12, thereby improving the efficiency of the cooling oil flowing back to the oil tank.

[0038] Furthermore, the guide groove 12 is arranged to be inclined, and the lower end of the guide groove 12 is connected to the leakage hole 11, so that the cooling oil in the guide groove 12 can flow to the leakage hole 11 more easily, thereby enabling the cooling oil to flow back to the oil tank more quickly during the process of the rack 1 being lifted in the oil tank.

[0039] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
