Rotating Shifting Member in Punch Presses to Save Space
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional punch presses require significant space for linear movement of the shifting member between abutment and retraction positions, limiting the reduction of occupied space.
Innovation Solution
A punch press design incorporating a rotating mechanism that allows the shifting member to rotate between abutment and retraction positions, eliminating the need for linear movement and reducing the overall space occupied.

Engineering Contradiction Analysis
1Ease of operation
If the shifting member is moved linearly between abutment position and retraction position, then the punching function is achieved, but the occupied space increases
Solution Approach 1:
The shifting member is changed from linear translation to rotational movement about a vertical axis. The rotating mechanism enables the shifting member to pivot between abutment position (where the basal end surface of the punch abuts against the opposing surface) and retraction position (where the basal end of the punch retracts into the recess), achieving the same functional effect while occupying less space.
2Productivity
If the shifting member is moved linearly to retract the punch, then the punching process can be controlled, but the device complexity increases due to space requirements
Solution Approach 1:
The control mechanism is simplified by changing from linear movement to rotational movement. The rotating mechanism with the shifting member that pivots about a vertical axis reduces the complexity of the overall device structure while maintaining the ability to control the punching process effectively.

AI summary
A punch press includes a die, a punch, a support that supports the punch, a shifting member, and a rotating mechanism. The shifting member includes an opposing surface that opposes the punch. The shifting member is movable toward and away from the die together with the support and the punch and rotatable about an axis extending in a direction in which the shifting member moves toward and away from the die. The shifting member includes a recess in the opposing surface. The rotating mechanism rotates the shifting member about the axis to shift the shifting member between an abutment position where the basal end surface of the punch is abut against the opposing surface and a retraction position where the basal end surface of the punch is retracted into the recess.
