Spring-Loaded Blank Positioning Guide for Forming Die Impact Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional positioning guide devices for forming dies in the automotive industry often result in inadequate blank positioning due to production fluctuations, leading to component defects, increased reworking, and downtime, especially with welded blanks, causing additional surface impairments and potential damage to the die.
Innovation Solution
A positioning guide device with a sloped positioning face mounted in a housing module that is linearly displaceable and preloaded by a spring system, allowing the guide to yield when a blank impinges on it, thus preventing hard impacts and enabling early detection of defective parts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a rigid positioning guide is used, then the positioning guide provides stable support, but it causes hard impacts and component defects when blanks are incorrectly positioned
Solution Approach 1:
The patent applies beforehand cushioning by introducing a damping element between the positioning guide and the blank. This damping element is designed to absorb impacts before they can cause damage to the component or the die. When a blank is incorrectly positioned and impacts the positioning guide, the damping element deforms to absorb the impact energy, preventing hard impacts and associated component defects while maintaining the stability of the positioning guide itself.
2Stability of the object's composition
If a rigid positioning guide is used, then the positioning guide maintains its position, but it causes production downtime when adjustments are needed
Solution Approach 1:
The patent applies dynamics by making the positioning guide adjustable rather than completely fixed. The positioning guide can be moved in the transverse direction to accommodate variations in blank positioning. This adjustability allows the system to adapt to different blank positions without requiring complete disassembly or manual intervention, thereby reducing production downtime while maintaining adequate positioning stability through controlled adjustability.
3Manufacturing precision
If the positioning guide is made adjustable, then the positioning precision is improved, but the device complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the positioning guide device into separate functional modules: a positioning guide component, a damping element, and an adjustment mechanism. This modular segmentation allows each component to perform its specific function independently, simplifying the overall design and maintenance while enabling precise positioning through coordinated operation of the segmented components. The adjustment mechanism can be independently controlled without affecting other parts of the system.
4Manufacturing precision
If manual correction of blank positioning is performed, then positioning accuracy is improved, but production efficiency decreases
Solution Approach 1:
The patent applies self-service by enabling the positioning guide to automatically adjust its position in response to incorrectly positioned blanks. The adjustment mechanism detects when a blank is not in the correct position and automatically moves the positioning guide to accommodate the blank, eliminating the need for manual intervention. This self-adjusting capability maintains high positioning accuracy while preserving production efficiency by removing the bottleneck of manual correction.
