Description

Technical Field

[0001] This utility model relates to the field of anti-deformation technology for forgings, specifically to anti-deformation tooling for heat treatment of forgings. Background Technology

[0002] During heat treatment, forgings are prone to deformation and warping due to factors such as thermal stress release, material phase transformation, and uneven cooling under high-temperature conditions. These defects severely affect the dimensional accuracy and mechanical properties of the workpiece. Especially in aerospace, automotive manufacturing, and other fields, the deformation control of precision forgings is directly related to the service safety of core components. For example, when heat treating large-diameter circular tubular objects, traditional anti-deformation tooling is mostly a fixed support structure, which cannot adapt to forgings of different sizes. Frequent replacement of matching fixtures is required, resulting in low production efficiency and high storage costs. Moreover, the operation is cumbersome and it is difficult to achieve synchronous and precise adjustment of multiple support points. Uneven stress can easily cause forgings to skew. To solve the above problems, we propose an anti-deformation tooling for forging heat treatment. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a tooling for preventing deformation during heat treatment of forgings, thereby solving the problems mentioned in the background section.

[0004] This utility model provides the following technical solution: a tooling for preventing deformation during heat treatment of forgings, comprising a circular plate, wherein multiple placement grooves are evenly provided on the top surface of the circular plate, and sliding blocks extending to the outside of the circular plate are slidably connected in the placement grooves. A support block is fixedly installed on one side of the sliding block outside the circular plate. A threaded rod is fixedly installed on the top surface of the circular plate and at its center. A sleeve is fitted around the outer ring of the threaded rod. An adjusting rod is hinged to the outer ring of the sleeve. The other end of the adjusting rod is hinged to one side of the top surface of the sliding block. A matching threaded tube is also provided on the outer ring of the threaded rod. A threaded sleeve is also fixedly installed on the bottom surface of the circular plate. A rotating plate is also provided at the lower part of the threaded sleeve.

[0005] In a preferred embodiment of this invention, the threaded tube is disposed on top of the sleeve, and the inner diameter of the sleeve is larger than the outer ring of the threaded rod.

[0006] As a preferred embodiment of this utility model, a plurality of rotating rods are uniformly fixedly installed on the outer ring of the threaded tube, and a limit plate is welded to the top of the threaded rod.

[0007] As a preferred embodiment of this utility model, the side of the support block away from the sliding block is arc-shaped.

[0008] As a preferred technical solution of this utility model, the inner walls of both sides of the placement groove opened on the top surface of the circular plate are provided with sliding grooves, and a slider is provided in the sliding groove. The outer wall of the slider is fixedly connected to the two side walls of the sliding block, and the vertical section of the sliding groove is T-shaped.

[0009] As a preferred embodiment of this utility model, a threaded post is welded to the top of the rotating plate, and the outer thread of the threaded post matches the inner thread of the threaded sleeve.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] 1. This heat treatment anti-deformation fixture for forgings, by setting threaded tubes, sleeves, adjusting rods, sliding blocks, and support blocks, allows the threaded tube to be rotated. The threaded tube will press down on the sleeve, causing the hinged adjusting rod to change its tilt angle. Since all adjusting rods are linked at the same angle, they will push the sliding block to achieve strict radial synchronous movement under the constraint of the T-shaped sliding groove. This allows the support block to support the inner ring of the circular tubular forging, making the inner ring of the circular tubular forging uniformly stressed, thereby preventing the forging from deforming during heat treatment.

[0012] 2. The heat treatment anti-deformation tooling for this forging, by setting up a rotating plate, threaded column and threaded sleeve, can first adjust the height of the circular plate according to the height of the large-diameter original tubular object to be supported. At this time, the rotating plate can be rotated, which can drive the threaded column to rotate. With the cooperation of the threaded sleeve, the height of the circular plate can be adjusted.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figures 1-3 The forging heat treatment anti-deformation fixture includes a circular plate 1, which can be made of high-strength heat-resistant alloy steel. The top surface of the circular plate has 6-8 rectangular placement slots evenly cut along the circumference. The inner walls of each placement slot are machined with T-shaped grooves. The sliding block 2 can be made of high-temperature nickel-based alloy. T-shaped sliders matching the grooves are welded to both sides of the sliding block 2, which allows the sliding block 2 to slide freely along the radial direction of the placement slot. The outer end of the sliding block 2 is fixedly installed with an arc-shaped support block 3. The support block 3 can support the inner ring of the circular tubular object to be heat treated, preventing deformation during heat treatment.

[0019] A threaded rod 6 is vertically welded to the center of the circular plate 1. A limiting plate 9 is welded to the top of the threaded rod 6. A matching threaded tube 8 and a sleeve 7 are sequentially installed at the bottom. The inner diameter of the sleeve 7 is larger than the outer diameter of the threaded rod 6. An adjusting rod 11 is hinged to the outer ring of the sleeve 7. The other end of the adjusting rod 11 is hinged to the top of the sliding block 2. Four to eight circumferentially evenly distributed rotating rods 10 are welded to the outer wall of the threaded tube 8. Anti-slip textures can be provided on the outer ring of the rotating rods 10.

[0020] The bottom of the circular plate 1 is welded with an internally threaded sleeve 4, and the top of the rotating plate 5 is welded with an externally threaded column 12. After the threaded column 12 and the threaded sleeve 4 are screwed together, the height of the circular plate 1 can be adjusted by rotating the plate 5.

[0021] The working principle is as follows: First, the height of the circular plate 1 can be adjusted according to the height of the large-diameter circular tubular object to be supported. At this time, the rotating plate 5 can be rotated, which in turn drives the threaded column 12 to rotate. With the cooperation of the threaded sleeve 4, the height of the circular plate 1 can be adjusted. Then, the circular plate 1 can be placed inside the inner ring of the large-diameter circular tubular object. At this time, the support block 3 can be positioned in the middle of the circular tubular object. Then, the threaded tube 8 can be rotated, and the threaded tube 8 will press down on the sleeve 7, causing the hinged adjusting rod 11 to change its tilt angle. Since all adjusting rods 11 are linked at the same angle, they will push the sliding block 2 to achieve strict radial synchronous movement under the constraint of the T-shaped sliding groove. This allows the support block 3 to support the inner ring of the circular tubular forging, making the inner ring of the circular tubular object bear uniform force, thereby preventing the forging from deforming during heat treatment.

[0022] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
