1results about How to "Reduce thinning" patented technology

This invention provides an integral forming apparatus and method for a corrugated, irregularly shaped thin-walled structure. The integral forming apparatus includes a spoke plate, a core mold, multiple petal molds, and an actuating ring. The core mold has multiple corrugated forming grooves along its circumference. The multiple petal molds are rotatably connected to the spoke plate and are spaced apart along the circumference of the spoke plate. Each petal mold has a boss that matches the shape of the forming groove. The actuating ring is sleeved on the outer periphery of the multiple petal molds and can move axially along the core mold, driving the multiple petal molds to converge towards the forming grooves, thereby forming the blank located between the petal molds and the forming grooves into a corrugated, irregularly shaped thin-walled structure. This invention features a simple process, good integrity, high forming accuracy, suitability for most commonly used thermoforming equipment, fast forming speed, fewer steps, and can greatly improve production efficiency.
