Ring Compression Mold With Spherical Clamping for Tight-Space Pipe Crimping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing crimping tools are limited in application scenarios, particularly in narrow or complex environments, and require multiple tools for crimping pipes of different sizes.
Innovation Solution
A ring compression mold with a fixed and movable mold group, featuring spherical grooves and clearance grooves, allows for adaptable crimping through spherical mating with calipers, enabling rotation and reduced opening size requirements, and a clamping mechanism with a pressing ring for different pipe sizes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the crimping head is directly arranged on the driving mechanism, then the crimping tool can realize the crimping of pipes, but the application scenarios are limited to open occasions and it is not suitable for narrow or complex areas
Solution Approach 1:
The crimping tool is divided into separate functional modules: the driving mechanism and the crimping head are separated, with the crimping head being detachably connected to the calipers. This segmentation allows the crimping head to be independently positioned and oriented, enabling operation in narrow and complex areas while maintaining a relatively simple overall structure.
Solution Approach 2:
The spherical groove and spherical mating portion enable the crimping head to rotate and position itself in different spatial orientations. This adds a rotational dimension to the tool's operation, allowing it to access pipes in narrow corridors, vertical shafts, and other complex three-dimensional spaces that were previously inaccessible.
2Adaptability or versatility
If existing crimping tools are designed for one crimping head, then the structure is simple, but multiple tools are needed when encountering situations where pipes of multiple different sizes need to be crimped
Solution Approach 1:
The calipers are designed with a universal spherical mating portion that can accommodate different crimping heads through detachable connection. This allows a single caliper body to perform multiple crimping functions by simply changing the crimping head, eliminating the need to carry multiple specialized tools for different pipe sizes while maintaining simple individual component structures.
3Ease of operation
If the calipers are required to open wide to accommodate the crimping mold, then the crimping can be performed, but the tool size increases and portability decreases
Solution Approach 1:
The spherical groove and spherical mating portion enable the crimping head to rotate into position, allowing the calipers to remain relatively closed while still accommodating the crimping operation. The spherical connection allows the crimping head to orient itself perpendicular to the pipe axis, reducing the opening requirement and making the tool more compact and portable.

AI summary
The present application particularly relates to connection tools include ring compression molds, clamping mechanisms, and clamping pipe connection tools. The ring compression mold is used to fit with calipers of the connection tool, including: a fixed mold and a movable mold group, which contains movable molds arranged on both sides of the fixed mold. A crimping hole for a crimping target to pass through is formed in the enclosure between the fixed mold and the movable mold group, a spherical groove for the ring mold to fit with the calipers is provided on the end of the movable mold away from the fixed mold, and the edge of the ring mold spherical groove is provided with a ring mold clearance groove and ring mold convex portions located on both sides of the ring mold clearance groove.
