ã€China Aluminum Industry Network】 Aluminum alloy formwork profiles are one of the more favored materials in the construction industry. With the development of the real estate industry in China and the advancement of marketization, the demand for aluminum alloy formwork profiles is increasing. The production of aluminum alloy formwork profiles requires moulding, and the moulds have an important decisive effect on the quality of aluminum alloy formwork profiles. The analysis of aluminum alloy formwork molds is of great help for the production and selection of high quality molds. Therefore, the analysis of 7050 aluminum alloy plate form profile molds is particularly important. The following are the features and techniques of aluminum alloy profile profile molds made by people in the industry. Difficulty analysis: (1) There are many varieties of template profiles, complex shapes, and large dimensional changes. Therefore, it is required to design and manufacture high-quality molds of different specifications, different structures, and different forms in order to ensure the forming, size, and positional accuracy, and a large amount of test work is required. (2) The template requires industrial mass production, the first key is to improve the service life of the mold. (3) The width-to-thickness ratio of flat wide formwork profiles is more than 100. It is difficult to ensure wide and thin wall part dimensional accuracy and plane clearance. It requires a special structure of wide spread, split flow die to reasonably distribute metal flow. In order to ensure the formation of the profile and high-precision size requirements, in particular to ensure ultra-high precision shape and position tolerance, the technical difficulty is even greater. (4) Most of the semi-hollow profiles in the formwork profile have a tongue ratio greater than 5, and the precision of the size and shape requires ultra-high precision. It requires a special structure of the mold to ensure its profile forming, and to achieve high precision, but also to ensure that the mold With sufficient strength, no deformation, no cracking, no collapse, guarantee high service life. (5) Template profiles require smooth surfaces, high dimensional accuracy and shape accuracy. Therefore, it is necessary to use high-quality die steels and strict die heat treatment processes and machining to implement all CNC process specifications in order to obtain high strength, high toughness, and high precision. High quality molds with low surface roughness.
Rolling tool bag is a type of tool bag that features wheels and a retractable handle, allowing it to be easily transported over longer distances. They are typically made from durable materials such as heavy-duty nylon, canvas, or leather and feature reinforced handles for easy lifting.
Rolling tool bags come in a variety of sizes and styles, ranging from small totes to larger bags with multiple compartments. They may also have additional pockets and compartments for organizing smaller items such as screws, nails, and drill bits.
The benefits of a rolling tool bag include:
Portability: The wheels and retractable handle make it easy to transport tools and equipment over longer distances without the need for heavy lifting.
Versatility: Rolling tool bags can accommodate a variety of tools and equipment, making them a versatile option for different trades and applications.
Easy to organize: Some models feature additional pockets and compartments for organizing smaller items, making it easy to keep tools and equipment organized and easily accessible.
When choosing a rolling tool bag, it is important to consider the size and weight of your tools, as well as the overall durability and quality of the bag. Additionally, consider the size and quality of the wheels for smooth rolling over various surfaces.
