Press Plunger Tilting Compensation via Force Flow Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current press technologies face challenges in achieving parallel plunger movement during machining processes, particularly in compensating for tilting caused by eccentric forces, which leads to inefficient force transmission and complex guide systems, and existing solutions are either inefficient or require complex structural additions.
Innovation Solution
The use of data from the force flow in a press to operate the plunger, allowing for tilting compensation or initiation through a control and regulation system that records and analyzes forces acting on the plunger, utilizing traction or pressure elements with adjustable stiffness and position, enabling targeted tilting control without complex protection mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a complex kinematic lever system is used to compensate for plunger tilting, then parallel plunger movement is achieved, but force transmission efficiency deteriorates
Solution Approach 1:
The invention extracts the tilting compensation function from the force transmission path by introducing a separate measurement and control system. Force sensors detect actual tilting, and the control unit independently calculates compensation values and adjusts drive train parameters, rather than using mechanical lever systems that interfere with force flow.
Solution Approach 2:
The invention implements feedback control by continuously measuring plunger tilting through force sensors in the drive train, processing these measurements to determine compensation requirements, and adjusting drive parameters accordingly. This closed-loop system achieves parallel movement without mechanical complexity.
2Manufacturing precision
If numerous mobile machine elements are used in the drive system, then plunger tilting compensation is possible, but device complexity increases
Solution Approach 1:
The invention replaces mechanical tilting compensation mechanisms with an electronic control system. Force sensors, a control unit, and software algorithms substitute for physical lever systems and mobile machine elements, achieving the same compensation function with fewer mechanical components.
3Force
If strong pressing forces are transmitted through the drive train, then machining requirements are met, but plunger tilting increases
Solution Approach 1:
The control system continuously monitors forces in the drive train through sensors and dynamically adjusts drive parameters to compensate for tilting caused by strong pressing forces, maintaining parallelism even under high load conditions.
Solution Approach 2:
The invention changes operational parameters of the drive train based on measured forces and tilting conditions. The control unit adjusts parameters such as motor torque, piston pressure, or linkages positions in real-time to counteract tilting effects while maintaining required pressing forces.

AI summary
A method of using data on the force flow in a press for the operation of a plunger, wherein the loads of the parts involved in the force flow can differ as a result of eccentrically operating forces, in such a way that the data about the respectively acting forces that, in accordance with Hooke's law, cause an extension or compression of a movement of the parts involved in the force flow, is measured and evaluated in relation to a drive device and a position of the plunger, whereupon a skewed position of the plunger is permitted or a skewed position of the plunger is counteracted or a skewed position of the plunger is set during operation of the press.
