[0030] 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, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0031] It should also be understood that the terminology used in this utility model specification is merely for describing specific aspects of the present application. It is important to understand that terms such as "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," and "counterclockwise," indicating orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present application. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of the stated features. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.

[0032] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0033] like Figures 1 to 8 As shown, this application provides a forging hammer machine, including a forging hammer assembly 10, a feeding assembly 20, and a frame 30. The forging hammer assembly 10 and the feeding assembly 20 are both mounted on the frame 30, and the feeding assembly 20 is located on one side of the forging hammer assembly 10. It is used to control the feeding accuracy of the platinum ring sleeved on the rubber tube, so that the forging hammer assembly 10 can hammer the platinum ring and the rubber tube together, solving the problem that the platinum ring cannot be accurately positioned on the rubber tube, and making the position of the platinum ring on the rubber tube uniform and accurate in mass production.

[0034] In an optional embodiment, the forging hammer assembly 10 is provided with multiple hammer blocks, at least two of which have arc-shaped holes 1111 for the passage of a rubber hose. The diameter of the arc-shaped holes 1111 gradually decreases at least partially in the direction away from the feeding assembly 20 to form a progressive hammering channel. This allows for gradient compression of the platinum ring through diameter changes, ensuring uniform plastic deformation and reducing turbulence effects during hose passage, thus minimizing the risk of surface scratches. The ratio of the maximum diameter to the minimum diameter of the arc-shaped holes 1111 is greater than or equal to 0.15 and less than or equal to 0.2 to ensure that sudden stress-induced cracking is avoided when the platinum ring undergoes progressive plastic deformation through the hammer blocks. If the ratio of the maximum diameter to the minimum diameter of the arc-shaped hole 1111 is too small, the diameter change will be too drastic, causing shear damage to the surface of the hose or excessive cold work hardening of the platinum ring. If the ratio of the maximum diameter to the minimum diameter of the arc-shaped hole 1111 is too small, the hammer block will not compress the platinum ring sufficiently, and the number of hammer blows will need to be increased to achieve the target fit.

[0035] By adopting the above technical solution, this application limits the ratio of the maximum diameter of the arc hole 1111 to the minimum diameter of the arc hole 1111 to the range of 0.15 to 0.2. This not only controls the plastic deformation of the platinum ring, balances the deformation efficiency of the platinum ring with the risk of material damage, avoids stress concentration, and ensures uniform plastic deformation, but also enables the combination of continuous feeding and hammering, making it suitable for mass production.

[0036] In an optional embodiment, the arc-shaped hole 1111 has a tapered section 1111a and a straight section 1111b. The length of the tapered section 1111a is not less than the length of the straight section 1111b, so that the platinum ring can be progressively compressed through the tapered section 1111a, avoiding stress concentration and reducing the risk of springback of the tubing within the tapered section 1111a. When the platinum ring and tubing enter the straight section 1111b from the tapered section 1111a, the straight section 1111b can play a shaping role, stabilizing the geometry of the deformed platinum ring and eliminating residual stress in the platinum ring during the deformation process.

[0037] In an optional embodiment, the ratio of the length of the tapered section 1111a to the length of the straight section 1111b is greater than or equal to 2.3 and less than or equal to 2.7, such that the residence time of the platinum ring and the tubing in the tapered section 1111a is greater than that in the straight section 1111b. This not only reduces the springback rate of the tapered section 1111a, but also balances the dynamics and residual stress of the platinum ring during plastic deformation.

[0038] In an optional embodiment, the ratio of the maximum diameter of the arc-shaped hole 1111 to the length of the tapered section 1111a is greater than or equal to 0.2 and less than or equal to 0.25. This not only ensures that the platinum ring can break through the yield strength when deformed, but also avoids shear strain exceeding 0.3% on the surface of the hose, so that the forging hammer machine can ensure the product qualification rate while ensuring production efficiency.

[0039] In an optional embodiment, the forging hammer assembly 10 includes a forging hammer structure and a drive structure 12 spaced apart. Multiple hammer blocks are movably mounted within the forging hammer structure. The drive structure 12 drives the multiple hammer blocks to open and close within the forging hammer structure, providing power for the opening and closing of the hammer blocks, thereby hammering the platinum ring onto the hose. Furthermore, this application can also adapt to the processing requirements of platinum rings and hoses with different outer diameters by replacing hammer blocks with different inner diameters.

[0040] In an optional embodiment, the forging hammer structure includes a rotating shaft 113, a bearing body 112, and a support body 114. The bearing body 112 is mounted on the frame 30 via the support body 114. The rotating shaft 113 is movably mounted inside the bearing body 112 and is connected to the drive structure 12 for transmission. Multiple hammer blocks are movably mounted inside the rotating shaft 113 and can generate radial displacement as the rotating shaft 113 rotates, so as to cooperate with the bearing body 112 to form a tensioning structure, thereby hammering the platinum ring together and combining the platinum ring with the rubber tube.

[0041] In an optional embodiment, the hammer block includes a first hammer block 111a, a second hammer block 111b, a third hammer block 111c, and a fourth hammer block 111d. An arc-shaped hole 1111 is disposed on the end faces of the first hammer block 111a and the second hammer block 111b opposite to each other. The third hammer block 111c and the fourth hammer block 111d are disposed on the side opposite to the first hammer block 111a and the second hammer block 111b. The first hammer block 111a, the second hammer block 111b, the third hammer block 111c, and the fourth hammer block 111d are movably mounted within the rotating shaft 113. The third hammer block 111c and the fourth hammer block 111d can engage with needle rollers spaced apart on the bearing body 112, generating radial displacement as the rotating shaft 113 rotates, thus achieving periodic opening and closing of the hammer block.

[0042] In an optional embodiment, the forging hammer structure has a guide block 115 on the side opposite to the drive structure 12. The guide block 115 has a guide groove 1151 adapted to the feeding assembly 20, so that the hose and the platinum ring sleeved on the hose can enter the forging hammer structure through the guide groove 1151 for hammering. The guide groove 1151 has a V-shaped structure.

[0043] In an optional embodiment, the forging hammer assembly 10 includes a mounting base 13, through which the forging hammer structure and drive structure 12 are mounted on the frame 30 to ensure structural rigidity and reduce hammering vibration interference.

[0044] In an optional embodiment, the forging hammer assembly 10 includes a coupling 14, and the drive structure 12 is connected to the forging hammer structure via the coupling 14 to drive the rotating shaft 113 to rotate.

[0045] In an optional embodiment, the feeding assembly 20 includes a clamping structure 22, a supporting structure 23, and a moving structure 21. The supporting structure 23 is disposed on one side of the clamping structure 22, and the moving structure 21 is used to drive the clamping structure 22 to move relative to the supporting structure 23, so as to move the tubing and platinum ring placed on the supporting structure 23, thereby achieving precise feeding of the tubing and platinum ring. This solves the problem that the platinum ring cannot be accurately positioned on the tubing, and makes the position of the platinum rings on the tubing uniform and accurate in mass production.

[0046] In an optional embodiment, the forging hammer machine further includes a control cabinet 40, a pressure regulating filter 50, an emergency stop switch 60, and a protective cover 70. The protective cover 70 is installed on the outside of the forging hammer assembly 10, the control cabinet 40 is located below the forging hammer assembly 10, the pressure regulating filter 50 is installed on one side of the control cabinet 40, and the emergency stop switch 60 is electrically connected to the forging hammer assembly 10 and the feeding assembly 20.
