Rescue workers all over the country found in actual rescue: Compared with the international famous brand shears, the ordinary domestic shears have a big difference in their performances, especially in terms of product stability; in addition, some shears are cutting round steel. The performance is very strong, and the performance can be significantly reduced even when the vehicle is sheared in an actual traffic accident rescue, even seriously affecting the efficiency of the rescue.
Based on the above-mentioned issues discovered by rescue workers, this article will systematically analyze the original intention of hydraulic shears, inspection standards, and vehicle conditions in stages, aiming to provide rescue workers with a brand-new method for selecting hydraulic tools: how to be practical Rescue pick a practical hydraulic shear.
As we all know, the R&D and production of hydraulic rescue tools in China started later than in Europe and America. Although the domestic hydraulic rescue tools have made great progress after more than 20 years of development: the product line is wider, the working pressure is increased, and the performance is also improved. In terms of the overall shear performance and overall stability of ordinary Chinese hydraulic rescue tools, there is still a big gap compared to internationally renowned brands.
The gap between ordinary domestic cuts and international standard cuts lies in:
1 , the reasons for raw materials.
Due to the uneven procurement of raw materials, the subsequent processing and the quality of finished parts and parts are stable.
2 , the product production process and processing level reasons.
Based on the reasons of the product processing technology and the level of processing technology, the quality accuracy of the parts in the finished product is unstable, which also affects the overall product performance and quality to a great extent.
3 , the reason for outsourcing processing.
The hydraulic rescue tool involves many parts and components that require heat treatment, surface treatment, etc. Due to the professional, cost, and efficiency considerations, these parts need to be processed by the external association factory, and the production level of the external association factory will have a direct impact. The overall performance and quality of the finished product.
4 , the reasons for the quality of purchased parts.
Any professional hydraulic rescue tool manufacturer needs to purchase standard parts, such as seals, hydraulic tubing, tool interfaces, etc., and these seals, interfaces, etc. as the core components of hydraulic rescue tools will also directly affect the performance of the product quality .
5 , the reasons for the differences in test standards.
The hydraulic rescue tool implements China's national fire inspection standard GB/T17906-1999 in China , Europe uses the EN inspection standard, and the United States complies with the NFPA inspection standard. Due to the differences in inspection standards, there are great differences in product design and practicality.
6 , the reasons for the staff
The quality of the company's personnel, and every responsible employee who has undergone rigorous training, is the guarantee for the production of qualified products.
7. Reasons for the equipment
Professional and advanced production and processing equipment is the premise of product stability and quality. High-precision equipment such as horizontal machining centers, vertical machining centers, universal grinding machines, and CNC lathes can guarantee the stability and consistency of products. In addition, three-coordinate, hardness testers and other testing instruments are also effective guarantees for product quality.
8 , the cause of the environment
It is also very important for the products to be in tall and bright workshops, to operate in accordance with the 5S standard and the ISO 9001 quality management system, and to have standardized management and a safe working environment to ensure product stability.
