Solution Overview
Problem
Existing cold forming machines face challenges in supporting forming forces on cold forming racks and adjusting the profile distance between racks efficiently, often requiring manual adjustments and clamping mechanisms that are cumbersome and inefficient.
Innovation Solution
A tool unit for a cold forming machine featuring a tool slide with a carrier and adjustment device, equipped with an electric motor and clamping device, allows for motor-driven adjustment of the cold forming rack's position and secure clamping, enabling precise profile distance control between racks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual clamping and adjustment methods are used for cold forming racks, then the structure remains simple, but the adjustment efficiency and productivity are reduced
Solution Approach 1:
The patent replaces the manual mechanical adjustment system with an automated motor-driven system. The adjustment motor (26) and clamping motor (35) eliminate manual intervention, enabling automated positioning and clamping of cold forming racks. This substitution significantly improves adjustment efficiency while the modular design keeps the overall structure manageable.
Solution Approach 2:
The system enables self-service operation through automated motors and control units. The adjustment device (25) and clamping device (19) can automatically perform positioning and securing operations without manual intervention, allowing the machine to service itself during operation cycles and improving overall productivity.
2Ease of operation
If cold forming racks are directly attached to tool slides with screw connections, then the support for forming forces is adequate, but the adjustment process becomes cumbersome and time-consuming
Solution Approach 1:
The clamping device (19) with clamping bodies (36) is designed to pre-position and secure the cold forming rack (18) to the carrier (15) before the forming operation begins. This preliminary action ensures the rack is properly attached and supported, eliminating the need for time-consuming manual screw connections during operation and reducing adjustment time.
Solution Approach 2:
The manual screw connection process is replaced with an automated clamping mechanism driven by a clamping motor (35). This substitution allows for rapid attachment and adjustment of cold forming racks without manual intervention, significantly improving ease of operation and reducing the time required for rack repositioning.
3Manufacturing precision
If automated adjustment devices with motors are introduced, then the adjustment precision and productivity are improved, but the device complexity increases
Solution Approach 1:
Manual positioning is replaced with motor-driven automated adjustment devices. The adjustment motor (26) provides precise control over the position of the carrier (15) and cold forming rack (18), while the clamping motor (35) automates the securing process. This substitution achieves high positioning precision through automated control, and the modular architecture manages the increased complexity by separating adjustment and clamping functions into distinct units.

AI summary
A tool unit for a cold forming machine. The tool unit has a tool slide, which is linearly movable in a longitudinal direction. A carrier for a cold forming rack of the tool unit is provided on the tool slide. By means of an adjustment device, the carrier can be positioned in a working direction. For this purpose carrier can be preferably linearly moved in working direction. In working direction the cold forming rack is supported on the carrier and is clamped by means of a clamping device against the carrier. For this purpose the clamping device has at least one clamping body, which can be moved opposed to a clamping force (F) in working direction and abuts against the cold forming rack. The clamping device is preferably not directly connected with the carrier. The clamping force is particularly supported indirectly or directly on the tool slide by passing carrier.
