Description

Technical Field

[0001] The utility model relates to the technical field of hubs, and more specifically, to a limit heat treatment frame for special-shaped hubs. Background Art

[0002] In the design of gravity casting molds, risers must be designed on the upper mold. For the produced special-shaped hubs, moving the riser position to the outside results in a large difference in the outer diameters at both ends of the hub. In the conventional flat heat treatment process, under the action of its own weight, the product will deform after heating, and it is necessary to set it vertically for furnace loading. The existing heat treatment frames are for conventional hubs with the same diameter at both ends. However, because the outer diameters at both ends of the special-shaped hubs are very different, the hubs will deflect when placed in the heat treatment frame and cannot maintain a vertical state.

Two support frames 3 are arranged on the upper part of the moving seat. The two support frames 3 are respectively located on the left and right sides of the upper part of the base 1. An installation plate 6 is arranged at one end of the two support frames 3 close to each other. One end of the installation plate 6 away from the support frame 3 is connected with a support bar 4. A support surface is arranged at one end of the support bar 4 away from the installation plate 6. The support surface is inclined, and the inclination direction of the support surface is inward and downward. A plurality of cushion blocks 5 are arranged on the support surface of the support bar 4. The two inclined support surfaces on both sides form a V-shaped support. The outer periphery of the larger-diameter end of the wheel hub can abut against the support surface, and the support is completed through the support surface. The cushion block 5 is higher than the support surface, and the smaller-diameter end of the wheel hub can abut against the cushion block 5, and the support is completed through the cushion block 5. Both ends of the wheel hub can be effectively supported, so as to complete the placement of the wheel hub.

[0021] As Figure 4 shown, a support groove 13 is opened on one side of the cushion block 5 away from the installation plate 6. The support groove 13 is V-shaped. The outer periphery of the smaller-diameter end of the wheel hub can be clamped into the V-shaped groove, which can play a role in limiting.

[0022] As Figure 3 、 Figure 4 shown, the cushion block 5 is slidably installed on the support surface of the support bar 4. A sliding groove 11 is opened along the length direction inside the support bar 4. A sliding hole 12 is opened at one end of the support bar 4 away from the installation plate 6. One end of the sliding hole 12 is communicated with the sliding groove 11, and the other end is communicated with the end face of the support bar 4. A limiting block 15 is slidably arranged in the sliding groove 11. A connecting rod 14 is connected to the lower part of the cushion block 5. The connecting rod 14 is located in the sliding hole 12.
