Link-Driven Former Timing for Precision Wire Rod Drawing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional former devices often result in defects due to the drawing-out unit hitting the wire rod before the forming mold has completed forming it, leading to issues with forming precision and deformation resistance.
Innovation Solution
A link-type driven former that includes a rotation guide shaft, an operation part vertically rotated by a drive source, and a connector part to move the drawing-out device forward or backward, allowing the drawing-out device to reach the wire rod faster and hit it slower than conventional systems, thereby improving forming precision and reducing deformation resistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the drawing-out unit operates at a fixed time in a conventional former, then the operation timing is simple to control, but the drawing-out unit hits the wire rod before the forming mold completes forming, resulting in defects and poor forming precision
Solution Approach 1:
The patent applies the dynamics principle by replacing the fixed-time operation mechanism with a dynamic link-type mechanism that automatically adjusts the drawing-out unit's timing based on the forming mold's operation cycle. The link-type driven former connects the punch unit's movement to the drawing-out unit, enabling the drawing-out operation to occur at the optimal moment after forming completion, thereby improving forming precision without requiring complex external control systems
Solution Approach 2:
The patent implements preliminary action by designing the link-type mechanism to pre-coordinate the drawing-out unit's movement with the punch unit's reciprocating motion. The connection rod and link mechanism are configured to activate the drawing-out unit at the precise moment when the punch unit completes its forming stroke, ensuring the wire rod is drawn out at the optimal timing before any defects can occur, thereby improving manufacturing precision
2Productivity
If the drawing-out unit hits the wire rod too early, then the operation speed is fast, but the forming precision deteriorates due to premature contact with the wire rod
Solution Approach 1:
The link-type driven former dynamically synchronizes the drawing-out unit's operation with the punch unit's movement cycle. The mechanism allows the drawing-out unit to remain stationary during the forming stroke and only activates when the punch unit reaches its return position, ensuring optimal timing that maintains both high productivity and forming precision by preventing premature contact while minimizing idle time

Function Achieved in This Case
The link-type driven former enhances forming precision, reduces forming load, and minimizes deformation resistance by enabling precise control over the hitting timing of the drawing-out device, preventing premature contact with the wire rod and improving the overall forging process.

AI summary
The present disclosure relates to a link-type drive former, and is directed to providing a link-type driven former, which may move a drawing-out device forward or backward so that the drawing-out device hits and draws out a wire rod to be drawn out which is fitted into a forming mold, and in particular, improve a forming precision of a target to be drawn out which is formed by the forming mold by enabling the drawing-out device to reach a front of the wire rod faster than a conventional former and making a time at which the drawing-out device hits the wire rod slower than that of the conventional former when the drawing-out device moves forward in order to draw out the wire rod formed by the forming mold. According to the present disclosure, the link-type driven former for moving a drawing-out device forward or backward so that the drawing-out device hits and draws out a target fitted into a forming mold includes: a rotation guide shaft; an operation part mounted on the rotation guide shaft and vertically rotated by a drive source; and a connector part having one side and the other side coupled to each of the operation part and the drawing-out device, and configured to pull and move the drawing-out device backward or push and move the drawing-out device forward by the vertical rotation of the operation part.
