Press Cutting Tool Sequential Clamping and Cutting Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing press cutting tools shake during operation, leading to defective products due to simultaneous pressing and cutting of connection heads, which results in an incomplete or uneven cut of the connection line.
Innovation Solution
A press cutting tool design featuring separate sliding pressing and cutting blocks, where the pressing block initially clamps the housing and the cutting block subsequently cuts the connection line, with the pressing block positioned further from the opening than the cutting block to minimize shaking and ensure a stable cutting process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the press cutting tool presses the housing and cuts the connection line simultaneously, then the operation is simple and fast, but the connection head shakes causing uneven cuts and defective products
Solution Approach 1:
The patent divides the simultaneous pressing and cutting operation into two sequential stages: first the pressing block clamps the housing, then the cutting block cuts the connection line. This segmentation eliminates shaking during cutting while maintaining operational efficiency, resolving the contradiction between speed and precision.
Solution Approach 2:
The pressing block performs the clamping action before the cutting block performs the cutting action. By securing the housing in advance, the connection head is stabilized prior to cutting, preventing shaking and ensuring flat cuts while maintaining a streamlined two-step operation.
2Device complexity
If the pressing block and cutting block are positioned close to the opening, then the tool structure is compact, but the connection head shakes during operation
Solution Approach 1:
The patent positions the pressing block and cutting block at different distances from the opening along the longitudinal axis of the tool. This spatial arrangement in one dimension allows each block to perform its function independently without interfering with the other, stabilizing the connection head while maintaining a relatively compact overall structure.
3Manufacturing precision
If the pressing block slides first to clamp the housing, then the cutting block slides to cut the connection line, then shaking is reduced and cut quality improves, but the operation sequence becomes more complex
Solution Approach 1:
The patent employs a dynamic sequential mechanism where the pressing block and cutting block slide in sequence along their respective connecting rods. The first connecting rod activates the pressing block, and upon completion, the second connecting rod activates the cutting block. This dynamic sequencing ensures stable cutting while maintaining an intuitive, flow-based operation that does not require complex user coordination.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design stabilizes the cutting process, reducing the likelihood of shaking and resulting in higher quality products with a more precise and flat cut of the connection line.
Implementation Method 1
the first connecting rod causes the pressing block to slide first to clamp and press the housing
Implementation Method 2
the second connecting rod causes the cutting block to slide to cut the connection line
Implementation Method 3
The first plier is pivotally connected to the second plier by the first pivot joint 95a at the end

AI summary
A press cutting tool is disclosed. The press cutting tool includes a first and second plier, a first and second connecting rod, an opening, a pressing block, and a cutting block. The first and second connecting rods are connected to the second plier. The opening is used for placing a connection head. The pressing block is connected to the first connecting rod for clamping housing. The cutting block is connected to the second connecting rod for cutting the connection line; wherein the pressing block and the cutting block slide separately, and an initial distance from the pressing block to the opening is greater than an initial distance from the cutting block to the opening. After the first and second plier are pressed, the pressing block slides first to clamp and press the housing, and then the cutting block slides to cut the connection line.
