[0016] This invention provides a device for preventing warping of arc-shaped forgings. The device provides fixed support for the forgings after forging and before heat treatment, which can effectively prevent warping deformation of the forgings during the cooling process after forging and the heating and cooling process of heat treatment.
[0017] A device for preventing warping of an arc-shaped forging includes: a first screw 1, a second screw 2, a first buckle 3, a second buckle 4, and a screw sleeve 5. The two ends of the screw sleeve 5 are threadedly connected to one end of the first screw 1 and one end of the second screw 2, respectively. The other end of the first screw 1 is connected to the first buckle 3, and the other end of the second screw 2 is connected to the second buckle 4. The first buckle 3 and the second buckle 4 clamp the end position of the arc-shaped forging to fix the arc-shaped forging in a manner that serves as the chord length of the forging.
[0018] In one possible embodiment, the other end of the first screw 1 is threadedly connected to the first buckle 3.
[0019] In one possible embodiment, the other end of the second screw 2 is threadedly connected to the second latch 4.
[0020] In one possible embodiment, the first screw 1 and the second screw 2 are hexagonal in shape.
[0021] In one possible embodiment, the threaded sleeve 5 is hexagonal in shape.
[0022] In one possible embodiment, the thread lengths of the first screw 1 and the second screw 2 are greater than or equal to half the length of the sleeve 5.
[0023] The specific method of using the device for preventing warping of arc-shaped forgings of this utility model is as follows:
[0024] Step 1: Make a device of appropriate size according to the size of the arc-shaped forging. The support rod has a threaded connection and consists of a threaded sleeve and two screws. The screws have a snap-fit structure. Both the threaded sleeve and the screws are hexagonal in shape. The support rod can be made larger or smaller by rotating the threaded structure according to the size of the arc-shaped forging, so as to fix and support the arc-shaped forging.
[0025] Multiple devices of different sizes can be set according to the curvature of each segment of the arc forging, and are used to clamp different curvature parts of the arc forging.
[0026] Step 2: After the forging is completed, quickly use the support rod device to fix the forging. Rotate the threaded structure to firmly fix the forging in place, so that the forging will not warp during the cooling process after forging.
[0027] Step 3: After the forging has cooled, rotate the threaded structure of the device in the opposite direction to remove the support rod.
[0028] Step 4: Before the forging is heat-treated, the forging is fixed and supported by the strut device. Then the device is put into the heat treatment furnace along with the forging for the heat treatment process.
[0029] Step 5: After the forging has been heat-treated and cooled, remove the support rod device.
[0030] The present invention will be further described in detail below through specific embodiments:
[0031] A certain arc-shaped forging has two arcs with different radii, R1 and R2 (R is the symbol for radius). Two different sizes of strut devices were manufactured for this arc-shaped forging, as follows: Figure 2 It is used to fix the curvature of the arc-shaped forging at points R1 and R2.
[0032] 1. Based on the forging drawing (as shown in Figure 1), design two sizes of devices (e.g., Figure 2 This is used to fix the R1 and R2 ends of the forging. In actual use, the length of the threaded sleeve E should be three times the thickness L2 of the screw C to ensure that the threaded sleeve has sufficient length and strength to withstand the compressive stress of the screw.
[0033] 2. Before forging the forging, adjust the length of L5 to be the same as the length of R2, adjust the length of L6 to be the same as the length of R1, and adjust the opening direction of the buckle D to be consistent, according to the size of R1 and R2.
[0034] 3. After the forging is completed and comes out of the mold, quickly use the buckle D of support rod 1 to lock the R2 arc and the buckle D of support rod 2 to lock the R1 arc. Then, depending on the tightness of the support rod, use a wrench to tighten the threaded sleeve E and rotate the threaded sleeve E so that the screw tightly supports the forging.
[0035] 4. After the forging has cooled, rotate the threaded sleeve E in the opposite direction to loosen the support rod and remove the support rod from the forging.
[0036] 5. When the forging is heat treated, repeat the process in step 2, and use the struts to support and fix the R1 and R2 arcs of the forging again, clamp the wall thickness of the forging, and make the screws tightly support the forging. Then the strut device enters the heat treatment furnace together with the forging for heat treatment.
[0037] 6. After the forging is heat-treated, it is taken out of the heat treatment furnace and supported by the strut during the cooling process. After the forging has cooled completely, the screw sleeve E is rotated in the opposite direction to loosen the strut and remove it from the forging. This ensures that the forging maintains its dimensions and does not warp or deform during the heating and cooling process of forging and heat treatment, thus ensuring the dimensional consistency of the forging.
