Stamping Machine Guide Rail Extension for Ram Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing automatic stamping or forming machines face issues with premature tool wear and tilting vibrations due to eccentric forming forces, leading to impaired processing quality and increased manufacturing and storage costs.
Innovation Solution
The use of longer guide rails with guide bodies arranged at a greater distance than the ram's vertical extent, supported by profile rails and a carriage system, enhances the machine's rigidity and reduces tilting vibrations by shifting the tipping point closer to the workpiece plane, thereby minimizing the impact on machining quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If guide rails are used with guide bodies arranged at a distance less than or equal to the ram's vertical extent, then the device complexity is reduced, but the ram tilting risk increases and processing quality deteriorates
Solution Approach 1:
The guide rails are extended beyond the vertical extent of the ram in the vertical dimension, creating a configuration where guide bodies can be positioned at greater distances from each other. This dimensional extension allows the guide bodies to be arranged at optimal positions for preventing ram tilting while maintaining a relatively simple guide device structure.
2Stability of the object's composition
If the distance between guide bodies is increased to reduce ram tilting, then the rigidity and processing quality improve, but the guide rail length and manufacturing costs increase
Solution Approach 1:
The guide device is segmented into multiple guide bodies distributed along the extended guide rails. Instead of using a single long guide body, the system uses multiple smaller guide bodies positioned at strategic locations, which provides effective ram guidance and tilting prevention while managing the overall length and complexity of the guide rail system.
3Ease of manufacture
If guide bodies are arranged close to the ram to simplify the structure, then the device complexity is reduced, but the tipping point shifts away from the workpiece plane reducing machining quality
Solution Approach 1:
The guide rails are positioned and extended in the vertical dimension to allow guide bodies to be arranged at optimal positions that shift the tipping point close to the workpiece plane. This vertical dimensionality change enables the guide bodies to be positioned effectively without complicating the overall structure, as the extension is along the existing vertical axis of the press.

AI summary
The machine has a frame (12) which mounts a tappet (20) linearly driven in a stroke direction, contains a drive device driving the tappet to a to-and-fro motion. The tappet is mounted by using multiple control devices which have a guide rail (45,46) on which a guidance body (64) is placed. The guide rails stationary connected with the tappet and the guidance bodies are stationary connected with the frame. The guide rails are longer than the tappet. The guide rails protrude on the upper side and the lower side above the tappet.
