Press Assembly with Depth Stops to Reduce Top-Heaviness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Pressing machines used in plumbing and heating installations are often top-heavy due to the weight of the pressing tools, making them difficult to handle.
Innovation Solution
A set comprising a drive device and multiple pressing tools with adjustable depth stops and coupling points that allow for the center of gravity to be shifted towards the gripping surface, reducing or eliminating top-heaviness by ensuring precise positioning and connection of the tools to the drive device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If pressing tools are connected to the drive device, then pressing functionality is achieved, but the machine becomes top-heavy and difficult to handle
Solution Approach 1:
The depth stop is made adjustable along the pressing tool's longitudinal axis, allowing dynamic repositioning to shift the center of gravity. This enables the operator to adapt the tool's balance characteristics to match different pressing operations and personal preferences, transforming a static top-heavy design into a dynamically adjustable system that optimizes handling ease.
Solution Approach 2:
The invention changes the positional parameter of the depth stop along the pressing tool's axis. By adjusting this parameter, the center of gravity of the pressing machine changes, thereby reducing top-heaviness. The depth stop can be positioned at multiple discrete locations to achieve different balance characteristics.
2Adaptability or versatility
If multiple pressing tools with different jaw widths are provided, then versatility is improved, but device complexity increases
Solution Approach 1:
The drive device is designed with a universal connecting part that can accommodate multiple pressing tools with different jaw widths. The standardized interface and adjustable depth stop mechanism allow a single drive device to perform multiple pressing functions across different pipe diameters, eliminating the need for multiple specialized tools.

AI summary
The invention relates to a press assembly comprising a drive device (100) and at least two press tools (200, 200.1) which have different jaw widths and which can be connected to the drive device in an alternating manner. The drive device (100) has a gripping surface (10), a connection part (30) for connecting one of the press tools (200, 200.1), and a roller tappet (50) for actuating the connected press tongs (200'). The connection part (30) is arranged on the front of the drive device (100) and has a plug receiving area (31) which is arranged in front of the gripping surface (10) when viewed in a plug-in direction (E) and into which the press tongs to be connected can be inserted from the front of the drive device (100). The connection part (30) additionally has a coupling point (32) for producing a force-fitting coupling between the connection part (30) and the press tongs inserted into the plug receiving area (31). The connection part (30) is equipped with at least two depth stops (33, 34) at different depths of the plug receiving area (31). Furthermore, each of the press tools (200, 200.1) is designed for only one of the depth stops (33, 34), and the press tools have a counter stop (210; 210.1) for the respective corresponding depth stop (33; 34) in order to come into contact against the corresponding depth stop (33; 34) when inserted into the plug receiving area (31). The invention additionally relates to a press machine (300).
