Multi-drive tooling for simultaneous multi-station press deformation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional press tooling limits the size of deformations that can be made in a single operation, requiring multiple hits and tool sets for larger forms, which is inefficient and costly.
Innovation Solution
A multi-drive tool system for presses that allows a single ram stroke to simultaneously actuate multiple stations, featuring drive members connected by a bridge member to enable simultaneous actuation and deformation of a workpiece across multiple stations.

Engineering Contradiction Analysis
1Length of moving object
If conventional single-station tooling is used, then the press can be operated with simple tooling, but the size of deformation is limited and multiple operations are required for large forms
Solution Approach 1:
The patent combines multiple drive members and tool stations into a single integrated multi-station tool assembly. The bridge member connects multiple drive members that are actuated simultaneously by a single ram stroke, merging the function of multiple separate tool operations into one coordinated action. This allows large deformations to be achieved in a single operation rather than requiring multiple sequential hits.
Solution Approach 2:
The patent transitions from single-station linear tooling to multi-station spatial arrangement. Multiple drive members are positioned at different stations along the bridge member, creating a spatial distribution of tooling elements. This dimensional expansion allows simultaneous engagement of multiple workpiece regions, enabling creation of large forms that extend beyond the capability of conventional single-point tooling.
2Length of moving object
If multiple tool sets are used for large deformations, then the desired deformation size can be achieved, but the fabrication process becomes more complex and costly
Solution Approach 1:
The multi-station tool assembly performs multiple tooling functions simultaneously through a single unified structure. The bridge member with multiple drive members can execute different deformation operations (punching, bending, forming) at multiple stations in one ram stroke, replacing the need for multiple specialized tool sets. Each drive member can be configured for different operations, providing universal functionality within a single tool assembly.
Solution Approach 2:
The patent merges multiple separate tool sets into one integrated multi-station assembly. Instead of using multiple independent tool sets that would need to be changed or positioned sequentially, the invention combines all necessary drive members and tooling elements into a single coordinated assembly that performs all required operations simultaneously, thereby reducing overall system complexity.
3Productivity
If a single ram stroke acts on one station, then the press mechanism remains simple, but the fabrication efficiency decreases due to multiple required operations
Solution Approach 1:
The patent enables continuous useful action by having a single ram stroke simultaneously actuate multiple drive members across multiple stations. Rather than the ram moving sequentially from one station to another (which would require multiple discrete operations), all deformation actions occur continuously and simultaneously in one stroke, maximizing the utilization of the ram's kinetic energy and improving fabrication efficiency.
Solution Approach 2:
The invention merges multiple tool stations into a single actuated assembly that responds to one ram stroke. The bridge member structurally connects the drive members, and through this merging, the press mechanism maintains its relative simplicity while achieving enhanced productivity through simultaneous multi-station operation.

AI summary
The invention involves a multi-drive tool for use on a fabricating press having a table with multiple stations. Each station can include a mount opening passing through the table. The multi-drive tool can have a bridge member relating to at least two drive members such that a ram stroke of the press simultaneously moves the drive members or components thereof in a direction toward the workpiece. The invention also involves a die shoe adapted for use on a press. A die-mounting recess configured to receive a die is formed in the top of the die shoe. The invention also provides a fabricating press in combination with a multi-drive tool, as well as methods of fabricating a workpiece.
