Description

Technical Field

[0001] This utility model relates to the field of PVC pipe technology, specifically a stretching device for PVC pipe processing. Background Technology

[0002] A tensile testing device for PVC pipe processing accurately simulates the tensile loads that PVC pipes may encounter during actual use, ensuring high accuracy and reliability of test results. By precisely controlling the tensile speed and force, the device can test the crack resistance of pipes under different loads, thereby evaluating their durability and safety. This is crucial for optimizing the PVC pipe manufacturing process and improving product quality. Furthermore, the device is simple to operate, easy to adjust, and adaptable to tensile testing of pipes of different specifications. The testing force and speed can be flexibly adjusted according to needs to meet different standards and requirements. The equipment has a compact design and small footprint, reducing wasted space.

[0003] For example, utility model patent CN214952630U discloses a stretching device for PVC pipe processing, relating to the field of PVC pipe processing. This stretching device for PVC pipe processing includes a guide rail, with a stretching mechanism slidably connected inside the guide rail. A support plate is fixedly installed at the right end of the guide rail, and a fixing mechanism is fixedly installed on the right side of the support plate. The stretching mechanism passes through the support plate and is slidably connected to it. A tensioning mechanism is sleeved on the right end of the stretching mechanism. This stretching device for PVC pipe processing fixes one end of the pipe through the fixing mechanism. By adjusting the rotating handle, the fixing sleeve can be rotated, thereby lifting the friction block to press tightly against the inner wall of the pipe. At this time, starting the motor can drive the slider to move within the guide rail through the rotation of the threaded guide rail. The fixing plate drives the stretching rod to stretch outward, thus stretching the pipe until it breaks. This allows for the analysis of pipe fracture under unidirectional force.

[0004] However, in the use of the equipment components in this application, no auxiliary limiting components are set for the snap-fit ​​components. As a result, after the PVC pipe is stretched and broken, the snap-fit ​​components are prone to large-scale shaking, which may cause damage to the components. Utility Model Content
