Description

Technical Field

[0001] The utility model relates to the technical field of six-sided top presses, and more particularly to a large cushion block mechanism of an ultra-large six-sided top press. Background Art

[0002] In existing technologies, the six-sided top press pad is a key component of the six-sided top press, and is widely used in the fields of superhard material synthesis, metal processing, machinery manufacturing, automobile manufacturing, etc. In these fields, the six-sided top press achieves the purpose of processing and assembly by pressing the workpiece on six sides, and the pad plays a role in supporting, transmitting pressure and protecting other components in this process. The pad is usually used in conjunction with components such as steel rings and top hammers. Through precise design and manufacturing, it ensures that it can stably transmit pressure and protect other components from damage under high-pressure environments. At the same time, it has a significant impact on the control of processing accuracy and the application of heat treatment processes.

[0003] At present, in the existing technology of the manufacturing process of the pad, since the pad material generates thermal stress during the heating and cooling process, this stress cannot be effectively released, resulting in deformation of the pad. The temperature difference between the inside and outside of the material is large, the thermal stress is concentrated, and the deformation is more significant. The current method of slowly heating and cooling is used to reduce the generation of thermal stress, and the heat treatment furnace is regularly inspected and maintained to ensure that the pad is heated evenly. However, this method is time-consuming and has higher labor costs.

[0004] Traditional large block installation methods usually require complex fixing procedures, often involving the use of multiple bolts or other fixing devices. This design makes the installation process cumbersome and time-consuming, requiring professional technicians and specific tools to complete. In a high-intensity production environment, this time-consuming installation process may cause long-term equipment downtime, directly affecting production efficiency and economic benefits. The disassembly process also faces similar challenges. When large blocks need to be replaced or repaired, the complex disassembly procedure is not only time-consuming, but also increases operational risks. Disassembly work in a small or inaccessible space may increase the safety risks of workers and easily cause damage to other parts of the equipment. Utility Model Content

[0016] (3) Beneficial effects

[0017] Compared with the prior art, the present invention provides a large pad mechanism for an ultra-large six-sided top press, which has the following beneficial effects:

[0018] 1. The design of tiny holes cleverly solves the problem of poor hardness caused by inconsistent internal and external temperatures of the pad during traditional heat treatment. By opening multiple groups of tiny holes on the surface of the pad, the contact area between the pad and water is significantly increased, making the heating and cooling during the heat treatment process more uniform. This design not only ensures the consistency of the overall temperature of the pad, but also effectively reduces internal stress, thereby improving the overall hardness and wear resistance of the pad. This innovative heat treatment method greatly improves the quality and performance of the pad, extends its service life, and provides reliable guarantee for the stable operation of the super-large six-sided top press.

[0019] 2. The design of the clamping mechanism cleverly solves the problem in the existing technology that large pads are not easy to install and disassemble quickly. Through the clever coordination of the clamping rod, clamping sleeve, clamping block and other components, the pads can be quickly clamped and disassembled. The design of the limit block and the top groove ensures precise positioning during the installation process, and the design of multiple sets of clamping blocks combined with the tension spring ensures the stability and reliability of the clamping. The sliding design of the locking sleeve further enhances the safety of the entire mechanism. This design not only greatly simplifies the installation and disassembly process of the pads, significantly improves operating efficiency, but also reduces maintenance costs and time. At the same time, the quick clamping mechanism also facilitates daily inspection and maintenance, improving the reliability and production efficiency of the entire press system.

[0020] 3. The design of the limit assembly further enhances the stability and reliability of the entire large pad mechanism. Through the coordinated work of the control sleeve, sliding sleeve, push rod and other components, the precise control and limitation of the lock sleeve position are achieved. The ingenious design of the arc groove and round hole, combined with the baffle and compression spring, forms a complex and efficient limiting mechanism. This design not only improves the operating accuracy and stability of the clamping mechanism, but also increases the safety of the entire large pad mechanism. By precisely controlling the position of the lock sleeve, accidental unlocking is effectively prevented, ensuring the stability of the pad during use. At the same time, the application of the compression spring increases the flexibility and reliability of the mechanism, making the entire limiting process smoother and more controllable. This design not only facilitates the operator to accurately judge the locking status, improves the convenience and safety of use, but also greatly reduces the risk of misoperation.
