Perforating Press Common Drive Member Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional piercing presses require separate drive elements for upsetting and piercing forces, leading to increased manufacturing complexity, cost, and overall size, which can be reduced by using a common drive member to exert both forces.
Innovation Solution
A piercing press design utilizing a single traverse and a hydraulic cylinder to drive both the compression and perforation processes through a detachable coupling mechanism, allowing for a more compact and rigid structure with improved force distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate drive elements are used for upsetting force and piercing force, then the piercing press can perform both forming operations, but the manufacturing complexity and overall size increase
Solution Approach 1:
The patent combines two separate drive elements into a single common drive member that sequentially performs both upsetting and piercing operations. The drive member includes a first forming device for upsetting and a second forming device for piercing, both integrated onto one movable component that is actuated by a single hydraulic cylinder, thereby reducing device complexity while maintaining operational versatility
Solution Approach 2:
The common drive member is designed as a universal component that can perform multiple functions: it acts as both the upsetting device and the piercing device depending on the operational phase. The member includes a receiving region for the billet and a piercing region with a piercing tool, allowing one component to execute both forming operations through sequential positioning
2Adaptability or versatility
If separate drive elements are used for upsetting force and piercing force, then both operations can be performed independently, but the overall height of the press increases
Solution Approach 1:
The patent implements a nested configuration where the piercing tool and piercing cap are positioned within or alongside the upsetting device structure. The common drive member integrates the piercing region inside or adjacent to the first forming device, allowing compact vertical arrangement that reduces overall press height while maintaining independent operational capability for both upsetting and piercing
3Adaptability or versatility
If separate drive elements are used, then each operation can be controlled independently, but the frame rigidity and dimensional accuracy decrease
Solution Approach 1:
By merging both forming devices onto a single common drive member, the patent ensures that both upsetting and piercing operations are executed from a unified, rigid reference frame. This integration eliminates potential alignment errors between separate drives and enhances frame rigidity, thereby improving dimensional accuracy of the final workpiece while maintaining sequential independent control through automated positioning

AI summary
The invention relates to a perforating press, comprising an in particular hollow-cylindrically shaped receiver (1) for receiving a workpiece (2), an upset-cap (8), wherein the upset-cap (8) can be pressed against the workpiece (2) by means of an upset-force for a first deformation of the workpiece (2), and a perforation cap (7) arranged on a piercer (4), wherein the perforation cap (7) is pressed into the workpiece (2) by means of a perforation force for a second deformation of the workpiece (2). Both the upset-force of the upset-cap (8) and the perforation force of the perforation cap (7) are applied by means of a common drive member (5, 6).
