Description

Technical Field

[0001] The utility model relates to the field of heat treatment, in particular to a tooling fixture for quenching and preventing deformation of circular flat sheets. Background Art

[0002] Metal heat treatment is a key process in mechanical manufacturing. Compared to other machining processes, heat treatment generally does not alter the workpiece's shape or overall chemical composition. Instead, it modifies the workpiece's internal microstructure or surface chemical composition, thereby enhancing or improving its performance. Its hallmark is improving the workpiece's intrinsic quality, which is generally not visible to the naked eye. To achieve the desired mechanical, physical, and chemical properties, heat treatment is often essential, in addition to the appropriate selection of materials and various forming processes. However, as heat treatment progresses, workpieces experience varying degrees of deformation. In actual production, this deformation complicates subsequent processes, particularly machining, significantly impacting production efficiency. Excessive deformation can lead to scrap and increased costs. This is particularly true for circular flat workpieces that require quenching. Due to the combined effects of thermal and structural stresses, deformation often exceeds customer drawing requirements, creating significant challenges for subsequent processing. Deformation is a challenging issue to address during heat treatment. While it is impossible to completely eliminate deformation, it is generally desirable to keep deformation within a certain range.

[0003] Due to their shape, round flat sheet products are difficult to place in a fixed position when loaded into a furnace. They are often placed on a string or in a square shape. During the quenching process, they are prone to warping or increased ovality, which may exceed the allowable range and lead to scrapping, increasing production costs, reducing customer satisfaction, and unstable product quality. Summary of the Invention

[0004] In view of the above-mentioned shortcomings of the prior art, the technical problem to be solved by the present utility model is that the existing circular flat sheet is prone to warping or increased ovality during the quenching process. Exceeding the allowable range leads to scrapping, increased production costs, reduced customer satisfaction, and unstable product quality. The utility model provides a circular flat sheet quenching anti-deformation fixture, which uses support rods for fixing and tightening, effectively solving the problem of warping or increased ovality. It is easy to fix when loading and placing in the furnace, convenient to operate, and improves production efficiency.

[0005] To achieve the above-mentioned purpose, the utility model provides a circular flat sheet quenching and anti-deformation tooling fixture, including two supporting discs, several supporting rods and fastening nuts. The supporting discs are sleeved on both ends of the supporting rods and fastened together by fastening nuts. The two supporting discs remain parallel when sleeved on the supporting rods; the several supporting rods form fixed support rods for the circular flat sheet.

[0006] Furthermore, the supporting disc includes three or more through holes, and the through holes are evenly spaced.

[0007] Furthermore, the number of through holes is 3 and they are evenly distributed at intervals of 120°.

[0008] Furthermore, the number of the support rods is the same as the number of the through holes, and corresponds one-to-one to the through holes.

[0009] Furthermore, both ends of the support rod are provided with threads.

[0010] Furthermore, the thread at one end of the support rod is longer than the thread at the other end.

[0011] Furthermore, the supporting disc, the supporting rod and the fastening nut are configured to be made of heat-resistant steel or austenitic stainless steel.

[0012] Furthermore, a fastening nut is arranged on the outer side of the supporting disc and cooperates with the thread.

[0013] Technical Effects

[0014] The utility model provides a circular flat sheet quenching and anti-deformation tooling fixture, which uses three support rods to form a 360° circumference and three points of support, and the two ends are fixed and tightened using support discs and fastening nuts, which effectively solves the problems of warping deformation or increased ovality, and is easy to fix when placed in the furnace, making it convenient for employees to operate and improving production efficiency.

However, it will be apparent to those skilled in the art that the present invention can be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to avoid obscuring the description of the present invention with unnecessary detail.

[0021] like Figure 1-3 As shown, the utility model provides a circular flat sheet quenching and anti-deformation fixture, including two supporting discs 1, a plurality of supporting rods 2 and fastening nuts 3. The supporting discs 1 are sleeved on both ends of the supporting rods 2 and are fastened together by the fastening nuts 3. The two supporting discs remain parallel when sleeved on the supporting rods; the plurality of supporting rods form fixed support rods for the circular flat sheet.

[0022] Among them, the support disc 1 includes 3 or more through holes, and the through holes are evenly spaced. The number of support rods is the same as the number of through holes, and corresponds to the through holes one by one. In this embodiment, there are 3 through holes, which are evenly distributed at intervals of 120°, and there are also 3 support rods. The 3 support rods form a 360° circumference with 3 points of support, which plays a role of triangular fixed support; the circular flat sheet can be placed on the inner circle formed by the 3 support rods for fixation, and the annular flat sheet can be inserted into the inner ring with the 3 support rods to form a fixation. Among them, the size and position of the through hole are customized by the size design of the circular flat sheet to be heated to ensure that the deformation of the circular flat sheet is within the effective range.

[0023] In this embodiment, both ends of the support rod are provided with threads, and the threads at one end of the support rod are longer than those at the other end. A fastening nut is provided on the outside of the support disc and engages with the threads. The short-end threads 21 are used to engage the nut and secure the support disc as a chassis; the long-end threads 22 are used to engage the nut and secure the support disc as a top cover. The thread length can be easily adjusted according to the number of products, thereby improving production volume and efficiency. In this embodiment, the short-end threads are 20 mm long and are used for nut fastening, while the long-end threads are set to 50 mm.

[0024] In this embodiment, the support disc, support rod, and fastening nut are made of heat-resistant steel or austenitic stainless steel, wherein the support disc is machined from section steel. The thickness of the support disc is set to be ≥15 mm to ensure stability during repeated use.

[0025] This utility model discloses a fixture for quenching and preventing deformation of circular flat sheets. Before use, it is first assembled using fastening nuts, a support disc, and a support rod (short threaded end) to form a loading base. The circular flat sheet is then placed or inserted into the three support rods. After loading is completed, the support disc is placed and then secured with fastening nuts. Finally, the sheet is heated in a furnace for subsequent processing. This utility model utilizes three points of circumferential fixation on the support rods to ensure that the circular flat sheet does not warp or increase in ovality during heat treatment. It is also easy to place and secure in the furnace, making it easy to operate and improving production efficiency.

[0026] The above describes in detail the preferred embodiments of the present invention. It should be understood that those skilled in the art can make numerous modifications and variations based on the concepts of the present invention without inventive effort. Therefore, any technical solutions that can be derived by those skilled in the art based on the concepts of the present invention through logical analysis, reasoning, or limited experimentation based on the existing technology should be within the scope of protection defined by the claims.
