Laser Die Positioning System for Press Bolster Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The alignment of referencing holes on a die and conical pins on a press bolster is challenging due to reduced angle of vision during die placement, leading to inaccurate positioning and potential damage, especially with increased die changing frequency and reduced setup times.
Innovation Solution
A press-die positioning system incorporating a crane, lifting lugs, ropes, a bolster with referencing holes and conical pins, and a laser that emits a linear light aligned with guiding lines on the die to ensure precise alignment of the die on the bolster.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the die is placed on the press bolster by crane without visual aid, then the placement process is simple, but the alignment precision between referencing holes and conical pins deteriorates due to decreased angle of vision
Solution Approach 1:
A laser device is introduced as an intermediary tool to project reference lines onto the die and press bolster. These laser-projected lines serve as visual mediators that bridge the gap between the operator's limited angle of vision and the precise alignment requirements of the referencing holes and conical pins, enabling accurate positioning without complex manual measurement procedures
Solution Approach 2:
The patent replaces traditional mechanical alignment methods (such as physical measurement tools and manual positioning) with an optical system. The laser device projects light-based reference lines that eliminate the need for complex mechanical measurement and adjustment procedures, thereby improving alignment precision while maintaining operational simplicity
2Productivity
If the die changing frequency is increased to meet production requirements, then the productivity improves, but the risk of misalignment and damage increases due to reduced setup time
Solution Approach 1:
The laser reference lines are prepared and projected onto the press bolster and die surfaces before the actual die placement operation begins. This preliminary visualization of alignment references allows operators to quickly and accurately position the die without time-consuming trial-and-error adjustments, enabling faster die changes while maintaining high alignment accuracy
Solution Approach 2:
The laser-projected reference lines provide immediate visual feedback to operators during the die placement process. By comparing the actual die position with the projected reference lines, operators can make real-time adjustments to ensure precise alignment, thereby maintaining reliability even when die changing frequency is increased
