Description

Technical Field

[0001] This utility model belongs to the technical field of metal forging equipment, and particularly relates to a modular axle forging anvil assembly. Background Technology

[0002] Axle production requires continuous operation. Under the influence of high-temperature impact, strong friction from metal flow, and alternating loads, the anvil cavity is prone to failure due to plastic deformation, network fatigue cracks, and thermal wear. Generally, an axle anvil can only produce about 100 axles before failing. A failed anvil cannot guarantee the external dimensions and surface quality of the axle, which is one of the main reasons for the large number of axles with black scale.

[0003] The connection points of existing anvils, such as the contact area between the medium anvil and the side anvil, often deform or crack due to stress concentration. This is especially true in high-frequency forging operations, where components wear out quickly and require frequent repairs or replacements, further increasing production downtime and maintenance costs. Utility Model Content

[0004] This utility model addresses the problems in the prior art by proposing the following technical solution:

[0005] A modular axle forging anvil assembly includes a medium anvil, side anvils symmetrically arranged on both sides of the medium anvil, a positioning and connecting mechanism, and a bolt assembly. The medium anvil has a reinforcing rib fixedly connected to its side wall near the side anvils, and the reinforcing rib has a movable cavity.

[0006] The positioning and connecting mechanism includes a positioning block that is slidably disposed in the moving cavity. The positioning block is inserted into a side anvil, and a connecting rod is fixedly connected to one side of the positioning block. A lifting seat is fixedly connected to the end of the connecting rod away from the positioning block.

[0007] The bolt assembly includes a bolt that is threaded to a side-type anvil, the end of which passes through a reinforcing rib and abuts against a lifting seat, and the end is provided with a tapered rod.

[0008] As a preferred embodiment of the above technical solution, the reinforcing rib and the medium anvil are integrally forged.

[0009] As a preferred embodiment of the above technical solution, the inner wall of the moving cavity is provided with a guide rail, and the positioning block is provided with sliders on both sides that match the guide rail.

[0010] As a preferred embodiment of the above technical solution, the movable cavity is fixedly connected to a partition plate, and a spring is fixedly connected to one side of the positioning block, with the end of the spring fixedly connected to the partition plate.

[0011] As a preferred embodiment of the above technical solution, the length of the tapered rod is 1 / 5 to 1 / 4 of the total length of the bolt.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. The side anvil of this utility model is detachably connected to the medium anvil through a positioning connection mechanism and bolt assembly, which makes it easy to replace the appropriate side anvil according to different axle models without replacing the entire component, thus reducing equipment costs and expanding the scope of application;

[0014] 2. The thread adjustment method of the bolt in this utility model, combined with the automatic reset function of the spring, simplifies the disassembly and assembly process of the side anvil, reduces equipment debugging time, and improves production efficiency.

[0015] 3.

[0021] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0022] Example

[0023] like Figure 1 , Figure 2 and Figure 3As shown, the modular axle forging anvil assembly includes a medium anvil 10, side anvils 11 symmetrically arranged on both sides of the medium anvil 10, a positioning and connecting mechanism, and a bolt assembly. A reinforcing rib 12 is fixedly connected to the side wall of the medium anvil 10 near the side anvil 11, and the reinforcing rib 12 has a moving cavity 13. The positioning and connecting mechanism includes a positioning block 20 slidably disposed in the moving cavity 13. The positioning block 20 is inserted into the side anvil 11, and a connecting rod 21 is fixedly connected to one side of the positioning block 20. A lifting seat 23 is fixedly connected to the end of the connecting rod 21 away from the positioning block 20. The bolt assembly includes a bolt 30 threadedly connected to the side anvil 11. The end of the bolt 30 passes through the reinforcing rib 12 and abuts against the lifting seat 23, and the end is provided with a tapered rod 31.

[0024] Specifically, the medium anvil 10, as the core load-bearing component, provides the main support surface for axle forging; the side anvils 11 are symmetrically distributed on both sides, adaptable to the forging needs of different parts of the axle (such as axle shoulders, journals, etc.), achieving multi-dimensional forging shaping and improving versatility. The reinforcing rib 12 connects the contact area between the medium anvil 10 and the side anvils 11, enhancing the overall structure's resistance to deformation and preventing cracking at the anvil connection due to excessive impact during forging. The movable cavity 13 provides installation and movement space for the positioning and connection mechanism, ensuring unimpeded sliding adjustment of the subsequent positioning block 20, laying the foundation for rapid positioning and connection of the medium anvil 10 and the side anvils 11.

[0025] The positioning block 20 is inserted into the side anvil 11, enabling initial positioning of the medium anvil 10 and the side anvil 11. This ensures accurate relative positioning during forging and prevents dimensional errors in axle forging due to misalignment. The positioning block 20 is slidably positioned within the moving cavity 13, allowing for adjustment of the insertion depth to accommodate side anvils 11 of different thicknesses or models, thus improving component compatibility. The connecting rod 21 rigidly connects the positioning block 20 to the lifting seat 23, enabling direct transmission of force from the lifting seat 23 to the positioning block 20. This ensures synchronous movement of the positioning block 20 and guarantees stability during the adjustment process.

[0026] Bolt 30 is threadedly connected to the side anvil 11. Rotating bolt 30 allows for precise control of its axial displacement, thereby moving the lifting seat 23 and enabling accurate adjustment of the positioning block 20 (such as tightening or loosening), facilitating quick assembly and disassembly of the side anvil 11. A reinforcing rib 12 runs through the end of bolt 30 and abuts against the lifting seat 23, concentrating the thrust of bolt 30 to the positioning block 20. This ensures a tight fit between the positioning block 20 and the side anvil 11, preventing loosening due to vibration during forging. The tapered rod 31 reduces the contact area between the bolt 30 end and the lifting seat 23, increasing local pressure and concentrating the thrust. Simultaneously, the tapered structure provides guidance, reducing bolt 30 offset during adjustment and improving adjustment accuracy.

[0027] like Figure 2 As shown, the reinforcing rib 12 and the medium anvil 10 are integrally forged structures.

[0028] It should be noted that the one-piece forging structure eliminates the connection gap between the reinforcing rib 12 and the medium anvil 10, avoids stress concentration, and significantly improves the structural strength and load-bearing capacity at the connection between the two; at the same time, it reduces the assembly process, reduces the risk of structural instability caused by assembly errors, and extends the service life of the component.

[0029] like Figure 2 As shown, the inner wall of the moving cavity 13 is provided with a guide rail, and the positioning block 20 has sliders on both sides that match the guide rail.

[0030] Specifically, the cooperation between the guide rail and the slider restricts the sliding direction of the positioning block 20, ensuring that it moves smoothly only along the axis of the moving cavity 13, avoiding deviation or jamming during sliding; at the same time, it reduces the friction area between the positioning block 20 and the inner wall of the moving cavity 13, reduces wear, and improves the smoothness of adjustment and the durability of the components.

[0031] like Figure 2 As shown, a partition plate 14 is fixedly connected to the movable cavity 13, and a spring 22 is fixedly connected to one side of the positioning block 20. The end of the spring 22 is fixedly connected to the partition plate 14.

[0032] Specifically, the partition plate 14 provides a fixed fulcrum for the spring 22, ensuring the stability of the spring 22's installation position and preventing misalignment when the positioning block 20 moves. When the spring 22 is in a compressed state, it stores elastic potential energy. When the bolt 30 loosens and the thrust decreases, the spring 22 can automatically push the positioning block 20 to reset, facilitating the disassembly of the side anvil 11. At the same time, during forging vibration, the spring 22 can buffer the impact force on the positioning block 20, reducing the risk of loosening of the connection.

[0033] like Figure 3 As shown, the length of the tapered rod 31 is 1 / 5 to 1 / 4 of the total length of the bolt 30.

[0034] It should be noted that this length ratio ensures that the tapered rod 31 can play the role of guiding and concentrating thrust (if the length is too short, the guiding effect will be insufficient and the thrust will be dispersed), while not being too long will cause the overall rigidity of the bolt 30 to decrease (avoiding the tapered rod 31 bending during forging vibration); at the same time, it adapts to the contact area of ​​the lifting seat 23 to ensure the efficiency of force transmission, while taking into account the adjustment accuracy and the structural strength of the bolt 30.

[0035] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
