Hydraulic Clamping Cylinder Drives for Plate Press Transport
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional transport devices for platen presses face challenges in minimizing sagging of pressed material stacks during loading and unloading, especially when dealing with large numbers of layers, such as papers or foils, due to limited installation space and the need for high clamping forces, which existing systems struggle to achieve without excessive construction modifications.
Innovation Solution
A transport device with hydraulic clamping cylinder drives and transverse drives that tension the clamping devices to minimize sagging, allowing for high clamping forces without detaching the material, using a combination of active and passive clamping jaws with integrated hydraulic feeds within the clamping strip, enabling efficient handling of thick stacks without requiring press modifications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If conventional clamping devices are used with limited installation space, then the press structure remains compact, but the clamping force is insufficient to minimize sagging of thick material stacks
Solution Approach 1:
The patent applies hydraulic clamping devices with cylinder-piston mechanisms to generate high clamping forces within limited installation space. The hydraulic system enables sufficient clamping force to minimize sagging of thick material stacks without requiring extensive construction modifications to the press structure.
2Length of moving object
If the press opening is kept small to maintain compact structure, then installation space is saved, but the loading device cannot adequately transport thick stacks of material
Solution Approach 1:
The loading device is designed to preliminarily clamp and stabilize the stack of material before it enters the press. By applying clamping force in advance during the loading process, the device ensures stable transport of thick stacks through the limited press opening without requiring a larger press structure.
3Stability of the object's composition
If more clamping devices are added to handle thick stacks, then sagging is reduced, but the device complexity and number of components increase
Solution Approach 1:
The patent combines multiple clamping functions into integrated loading and unloading devices that operate on both sides of the press. By merging the clamping actions and using coordinated cylinder-piston mechanisms, the system achieves stable transport of thick stacks without proportionally increasing the number of independent clamping devices.
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
The solution effectively reduces sagging during transport and loading/unloading of pressed material stacks, allowing for the processing of stacks up to 40mm thickness with minimal contact with hot press plates, and can handle multiple layers without press width adjustments, ensuring high-quality and efficient production of compact and laminated panels.
Implementation Method 1
The clamping drives are designed as hydraulic clamping cylinder drives
Implementation Method 2
transverse drives connected thereto to receive the stack of material/press plate and can be moved apart transversely to the transport direction to clamp the stack of material/press plate
