Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional splitting spinning apparatuses are unable to effectively work an outer cylinder, necessitating additional processing steps and reducing efficiency.
Innovation Solution
A splitting spinning apparatus with a roller that can switch between states to form both an inner and an outer cylinder, utilizing drive mechanisms to facilitate the formation of the outer cylinder without pre-processing the baseplate edge, and incorporating a roller carrier and locking mechanism for state switching.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional splitting spinning apparatus is used to form inner cylinder, then inner cylinder can be produced, but outer cylinder cannot be worked
Solution Approach 1:
The roller is designed to perform multiple functions: it can split-spin the blank to form the inner cylinder, and subsequently spin the baseplate to form the outer cylinder. This multi-functional roller eliminates the need for separate processing equipment, directly resolving the contradiction between versatility and device complexity.
Solution Approach 2:
The roller's position and orientation are dynamically adjustable through the roller carrier mechanism. The roller can be positioned in different states (first state for inner cylinder, second state for outer cylinder) by rotating the roller carrier, enabling the same apparatus to handle different processing requirements without structural modification.
2Adaptability or versatility
If roller is fixed in one state, then processing is simple, but cannot switch between inner and outer cylinder formation
Solution Approach 1:
The roller carrier enables dynamic repositioning of the roller between two states. The carrier can be rotated to change the roller's orientation from the first state (for inner cylinder) to the second state (for outer cylinder), providing adaptability without requiring complete apparatus redesign.
Solution Approach 2:
The roller carrier acts as an intermediary mechanism between the fixed roller and the processing requirements. It provides the necessary movement and positioning capability, mediating between the simple fixed roller structure and the need for state switching, thus minimizing the increase in device complexity.
3Ease of manufacture
If additional processing steps are added to work outer cylinder, then outer cylinder can be formed, but production efficiency decreases
Solution Approach 1:
The apparatus enables continuous processing where the roller sequentially forms both the inner cylinder and outer cylinder without interrupting the production flow. The baseplate is first used to form the inner cylinder, then the same baseplate is spun to form the outer cylinder, eliminating the need for separate processing steps and maintaining continuous productive action.
Solution Approach 2:
The formation of inner and outer cylinders is merged into a single continuous operation using the same roller and baseplate. Instead of separate processing steps for inner and outer cylinders, the apparatus combines both operations, directly improving productivity while ensuring ease of manufacture.
4Productivity
If roller directly spins baseplate to form outer cylinder, then efficiency improves, but roller wear may be uneven
Solution Approach 1:
The roller carrier enables dynamic adjustment of the roller's position and orientation during processing. By controlling the roller's movement and contact points, the system can distribute wear more uniformly across the roller surface, extending its service life while maintaining high productivity in outer cylinder formation.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enhances production efficiency by allowing direct formation of the outer cylinder, extends roller wear life through uniform wear, and simplifies demolding by enabling easy extraction of the mandrel and squeezing roll.
Implementation Method 1
the roller moves along the radial direction of the blank to splitting spin the upper side of the blank... the trumpet flange is deformed to form an inner cylinder... the roller moves upward to cause the baseplate to be continuously deformed to form the outer cylinder
Implementation Method 2
after the squeezing roll compresses the baseplate tightly against the inner plate, the roller moves along the radial direction of the blank
