AI Technical Summary
The existing six-sided top press's top hammer fixing structure is prone to deformation under long-term high pressure, causing the top hammer to shift position, affecting the equipment's accuracy and service life.
The design combines a connecting body with a limiting structure and an anti-deformation structure. The limiting structure increases the fixing points and disperses the pressure, while springs and pads increase the preload. The anti-deformation structure reduces deformation through the support cylinder and the protective outer ring, and the oil inlet reduces friction.
It effectively prevents the top hammer from loosening in high vibration environments, improves the compressive strength and deformation resistance of the assembly ring, extends the service life of the equipment, and enhances the stability of the equipment.
