Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of tooling for shell-type parts, and in particular to a tooling for preventing shell-type parts from collapsing due to heat. Background Technology
[0002] The structure of a certain shell-type part is as follows Figures 1-2 As shown, the shell-like part 1 is generally conical in shape, with a conical cavity inside. Two through slots 2 connected to the conical cavity are formed on the front side of the shell-like part 1. Support plates 3 are fixed to both the left and right sides of the shell-like part 1, and each of the four support plates 3 has a through hole 4. The shell-like part 1 is made of aluminum alloy. After the shell-like part is cast, the process requires it to be placed in a furnace for heat treatment to improve its mechanical strength and eliminate internal stress.
[0003] However, during the heating process of shell-type part 1 in the furnace, the outer material of shell-type part 1 collapses [because the wall thickness of shell-type part 1 is small, it undergoes thermal deformation when heated, and the outer material of shell-type part 1 collapses]. Therefore, the production quality of shell-type part 1 is reduced, while the process requires that the outer material of shell-type part 1 should not undergo any deformation after heat treatment.
[0004] Therefore, there is an urgent need for a tooling that prevents shell-type parts from collapsing and improves the production quality of shell-type parts. Utility Model Content
[0005] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a tooling for preventing shell-type parts from collapsing and improving the production quality of shell-type parts by preventing shell-type parts from collapsing due to heat.

[0007] The central column is also fixed with a first protective plate and a second protective plate. A first sliding sleeve is fixed on the bottom surface of the first protective plate. A first central hole is opened in the first sliding sleeve, penetrating the top surface of the first protective plate. A first locking screw is threaded onto the first sliding sleeve. The first protective plate is sleeved on the central column through the first central hole. Under the threaded connection force between the first locking screw and the first sliding sleeve, the first protective plate is fixed on the central column.
[0008] A second sliding sleeve is fixed on the bottom surface of the second protective plate. A second central hole is opened in the second sliding sleeve, penetrating the top surface of the second protective plate. A second locking screw is threaded onto the second sliding sleeve. The second protective plate is sleeved on the central column through the second central hole. Under the threaded connection force between the second locking screw and the second sliding sleeve, the second protective plate is fixed on the central column.
[0009] The tooling also includes a middle plate and a top plate. Guide holes are provided at the four corners of the middle plate and the top plate, and the four guide holes correspond to the four columns respectively. The front and rear end faces of the middle plate and the top plate are threaded with third locking screws. The middle part of the middle plate and the top plate are provided with cavities that match the outer contour of the shell-like parts.
[0010] The base plate is equipped with handles on both the front and rear ends for easy handling by workers.

[0029] The present invention will be further described below with reference to the accompanying drawings. The scope of protection of the present invention is not limited to the following description:
[0030] like Figures 3-8 As shown, a tooling for preventing shell-like parts from collapsing due to heat includes a base plate 5. A vertically arranged central column 6 is fixed in the middle of the top surface of the base plate 5. Four threaded holes 7 are opened on the top surface of the base plate 5 in the circumferential direction around the central column 6. The four threaded holes 7 correspond to the four through holes 4 of the shell-like part 1. Four upright columns 8 distributed around the central column 6 are also fixed on the top surface of the base plate 5. The diameter of the four upright columns 8 is smaller than the diameter of the central column 6.
[0031] The central column 6 is also fixed with a first protective plate 9 and a second protective plate 10. A first sliding sleeve 11 is fixed on the bottom surface of the first protective plate 9. A first central hole 12 is opened in the first sliding sleeve 11, penetrating the top surface of the first protective plate 9. A first locking screw 13 is threadedly connected to the first sliding sleeve 11. The first protective plate 9 is sleeved on the central column 6 through the first central hole 12. Under the threaded connection force between the first locking screw 13 and the first sliding sleeve 11, the first protective plate 9 is fixed on the central column 6.
[0032] A second sliding sleeve 14 is fixedly provided on the bottom surface of the second protective plate 10. A second central hole 15 is provided in the second sliding sleeve 14, penetrating the top surface of the second protective plate 10. A second locking screw 16 is threadedly connected to the second sliding sleeve 14. The second protective plate 10 is sleeved on the central column 6 through the second central hole 15. Under the threaded connection force between the second locking screw 16 and the second sliding sleeve 14, the second protective plate 10 is fixed on the central column 6.
[0033] The tooling also includes a middle plate 17 and a top plate 18. Guide holes 19 are provided at the four corners of both the middle plate 17 and the top plate 18, each corresponding to one of the four columns 8. Third locking screws 20 are threaded onto the front and rear end faces of both the middle plate 17 and the top plate 18. A cavity 21, matching the outer contour of the shell-like part 1, is provided in the middle of both the middle plate 17 and the top plate 18. Weight-reducing grooves are provided at the four corners of both the middle plate 17 and the top plate 18.
[0034] Handles 22 for easy handling by workers are fixed on both the front and rear ends of the base plate 5. The first guard plate 9 and the second guard plate 10 are arranged parallel to each other, and the size of the first guard plate 9 is larger than the size of the second guard plate 10.
[0035] The working process of this utility model is as follows:
[0036] S1. The worker takes out a shell-like part 1 that is to be heat-treated;
[0037] S2. The worker places the conical cavity of the shell-like part 1 outside the second protective plate 10 and the first protective plate 9, and then supports the four support plates 3 on the shell-like part 1 on the top surface of the base plate 5. At the same time, the worker ensures that the through holes 4 in the four support plates 3 correspond to the four threaded holes 7 on the base plate 5. At this time, the first protective plate 9 and the second protective plate 10 support the inner wall of the shell-like part 1.
[0038] S3. The worker uses four screws 23 to pass through the through holes 4 on the four support plates 3, and then thread them into the threaded holes 7 on the base plate 5 to fix the shell-like part 1 to the base plate 5, such as... Figure 9 As shown;
[0039] S4. The worker places the four guide holes 19 of the intermediate plate 17 onto the four columns 8 respectively, while ensuring that the cavity 21 of the intermediate plate 17 matches the outer conical surface of the shell-like part 1. Then the worker tightens the third locking screw 20 on the intermediate plate 17 to fix the intermediate plate 17 between the four columns 8.
[0040] S5. The worker places the four guide holes 19 of the top plate 18 onto the four columns 8 respectively, ensuring that the cavity 21 of the top plate 18 mates with the outer conical surface of the shell-like part 1. Then, the worker tightens the third locking screw 20 on the top plate 18 to fix the top plate 18 between the four columns 8, thus finally completing the tooling of the shell-like part 1. Figure 10 As shown;
[0041] S6. After the shell-type part 1 is tooled, the worker lifts the handle 22 to put the entire tooling and shell-type part 1 into the furnace body, and heat-treats the shell-type part 1 through the furnace body.
[0042] In step S2, the first protective plate 9 and the second protective plate 10 both support the inner wall of the shell-like part 1. In steps S4 and S5, the middle plate 17 and the top plate 18 support the outer wall of the shell-like part 1. In other words, both the inner and outer walls of the shell-like part 1 are protected, thereby effectively preventing the collapse of the outer material of the shell-like part 1 during the heating process, and thus greatly improving the production quality of the shell-like part 1.
[0043] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
