[0022] It is obvious that the drawings in the following description are only some examples or embodiments of the present application, and for those of ordinary skill in the art, the present application can also be applied to other similar scenarios without creative labor. In addition, it can be understood that although the efforts made in the development process may be complex and lengthy, for those of ordinary skill in the art related to the content disclosed in the present application, some design, manufacture or production changes based on the technology disclosed in the present application are only routine technical means and should not be understood as insufficient disclosure of the present application.

[0023] However, there will be cases of omission of unnecessary detailed description. For example, there are cases of omitting detailed description of well-known matters, repeated description of actually identical structures. This is to avoid the following description from becoming unnecessarily lengthy and to facilitate understanding by those skilled in the art. In addition, the drawings and the following description are provided to enable those skilled in the art to fully understand the present application and are not intended to limit the subject matter recited in the claims.

[0024] Please refer to Figures 1-5 As shown in the drawings, in the utility model embodiment, a manufacturing tool for a crown block heavy hammer U-shaped ring comprises a base 1, a working plate 2 is detachably connected on the base 1, a limiting circular tube 10 is arranged above the base 1, a limiting assembly 3 is further arranged above the base 1, a placing area 4 is formed between the limiting assembly 3 and the limiting circular tube 10, a placing frame 5 is arranged on one side of the outer portion of the working plate 2, an auxiliary clamping hand 6 is placed in the placing frame 5, the auxiliary clamping hand 6 is used for clamping the unformed part of the U-shaped ring 100 to be processed and outwardly prying, so as to realize the plastic processing of the U-shaped ring 100 to be processed.

[0025] The operator puts the U-shaped ring 100 to be processed into the placement area 4 formed by the limiting circular tube 10 and the limiting assembly 3. Due to the presence of the limiting assembly 3, the U-shaped ring 100 to be processed is automatically limited in the correct position, preventing position deviation. The operator clamps the two ends of the U-shaped ring 100 to be processed by the auxiliary clamping hand 6 and pulls it outward, thereby completing the forming operation of the end of the U-shaped ring 100 to be processed, making it reach the design standard. With the geometric restriction of the placement area 4 formed by the limiting circular tube 10 and the limiting assembly 3 of the tooling and the auxiliary clamping hand 6, each U-shaped ring is shaped in the same way, ensuring the consistency and standardization of the product, enabling the standardized production of the weight U-shaped ring, significantly reducing the probability of weight limiting failure or misoperation caused by non-standard U-shaped ring production, and further improving the stability and reliability of the crown block weight protection system.

[0026] In one embodiment, referring to Figure 1 , Figure 2 and Figure 3 , the work plate 2 is provided with a through hole 21, and the limiting circular tube 10 extends through the through hole 21 to the upper part of the work plate 2. The through hole 21 allows the limiting circular tube 10 to penetrate the work plate 2 instead of being fixed on the surface of the work plate 2. The part of the limiting circular tube 10 that penetrates above the work plate 2 forms a limiting functional area on the upper part of the work plate 2.

[0027] In one embodiment, referring to Figure 1 , Figure 2 and Figure 3 , the limiting assembly 3 includes three limiting screws 31 uniformly arranged on the base 1 in the circumferential direction. The three limiting screws 31 are symmetrically arranged in the circumferential direction by 120°, forming an equilateral triangular limiting structure that surrounds the limiting circular tube 10 to form a regular geometric space. The symmetric arrangement effectively forms uniform limiting pressure, ensuring that the U-shaped ring 100 to be processed will not tilt or deform due to eccentricity during processing.

[0028] Specifically, referring to Figure 1 and Figure 3 , the work plate 2 is provided with three limiting holes 22 in the circumferential direction. The three limiting screws 31 extend through the three limiting holes 22 to the upper part of the work plate 2. The three limiting screws 31 and the limiting circular tube 10 form a placement area 4. The placement area 4 becomes a "fixed mold" for the U-shaped ring 100 to be processed. The outer wall of the U-shaped ring 100 to be processed rests on the limiting circular tube 10, and the inner wall is limited by the three limiting screws 31, ensuring that the deformation during processing is within the design range. Each U-shaped ring maintains the same position and posture when placed due to structural limitations, making subsequent clamping and bending processing actions highly consistent, which is beneficial for standardized production.

[0029] Further, referring to Figure 1 andFigure 3 As shown in the drawings, the upper part of the work plate 2 is provided with a mounting hole 23, and the work plate 2 is connected to the base 1 by passing through the mounting hole 23 with a fastening bolt. The mounting hole 23 is a hole position for the fastening bolt, and the bolt passes through the mounting hole 23 and is screwed into the base 1 to complete the fixed installation of the work plate 2. The work plate 2 can be detachably connected to the base 1, which is convenient for maintenance and replacement.

[0030] Please refer to Figure 2 、 Figure 4 and Figure 5 As shown, the auxiliary clamping hand 6 includes a mounting plate 61 placed in the placing frame 5, and the upper part of the mounting plate 61 is provided with a fixed plate 62. The upper part of the mounting plate 61 is provided with a sliding groove 612, and the sliding groove 612 is slidably connected with a moving plate 63. The moving plate 63 can slide forward and backward in the sliding groove 612, and can form a clamping area with variable width between the fixed plate 62. The clamping requirements of different sizes of U-shaped rings or different bending parts can be met by sliding adjustment, realizing adaptability and flexibility.

[0031] Further, please refer to Figure 2 、 Figure 4 and Figure 5 As shown, the mounting plate 61 is provided with a plurality of bolt holes 611, and the moving plate 63 is provided with a fixed hole 631. The moving plate 63 is provided with a limiting bolt 64 for passing through the bolt hole 611 and the fixed hole 631. Under the guidance of the sliding groove 612, the moving plate 63 can slide forward and backward, and the user can adjust the clamping width according to different U-shaped ring shapes. When sliding to the appropriate clamping position, the limiting bolt 64 passes through the fixed hole 631 on the moving plate 63 and the bolt hole 611 on the mounting plate 61 to fix the installation position of the moving plate 63.

[0032] It should be noted that the present application is not limited to the above-mentioned embodiments.
