Description

TECHNICAL FIELD

[0001] The utility model relates to the field of plastic structure detection equipment, concretely to a plastic stress residual detection equipment. BACKGROUND

[0002] In modern industrial production, plastics are widely used in many fields, and the stability of their quality and performance is crucial. Stress residual, as a key factor affecting the quality of plastics, has a direct correlation with the durability and safety of various plastic products. Therefore, plastic stress residual detection is a key link to ensure product quality.

[0003] Currently, there are various plastic stress residual detection technologies, but when facing different types of plastics, there are cases of insufficient detection accuracy. Many detection equipment has relatively single functions and is difficult to fully adapt to the challenges brought by the differences in the properties of various plastics. In actual application, it is often difficult to meet the demand for accurate detection of plastic stress residual in complex production environments.

[0004] Traditional detection technology usually fixes the plastic sample on the detection table first, and then uses a single stress application method, such as simple extrusion or stretching. After that, some conventional physical measurement methods, such as measuring the degree of deformation, are used to indirectly judge the stress residual situation. This method lacks targeted treatment for different plastic properties and the detection means is not rich and flexible.

[0005] Due to the lack of accurate differentiation and adaptation of different plastic properties in existing technology, it is easy to cause large deviation in detection results. In the detection process, because the detection method cannot be flexibly adjusted according to the type of plastic, the stress residual of some special plastics cannot be effectively detected. For example, for some new composite materials, the conventional detection method is difficult to accurately capture the internal stress situation, thereby affecting the accurate evaluation of product quality, which is not conducive to the quality control and optimization improvement of plastic products.
