Color steel sandwich panel roof design（二）

  1. All seams are arranged in the longitudinal direction consistent with the roof drainage. General shall make the flow direction and the longitudinal seams cross, to avoid longitudinal joints diffuse water phenomenon. Between the roof and the roof longitudinal seam joints between the board and the board using water-based structure, waterproof material, supplemented by a method, the gap does not appear the phenomenon of water under normal circumstances only waterproof structure, but in stormy weather, in flanging buckle slot between its side walls on steel sandwich panel, since the parts processing, installation and other reasons, can not be completely consistent color and is very smooth steel surface, the friction coefficient is very small, often appear slanting rain trans overshoot. Therefore, it is necessary to be waterproof material.

Color steel sandwich panel roof design(一）

  

  Sandwich panels used in construction, is a new development of building technology, in which there is not a previous set of load-bearing building board, insulation, waterproofing and renovation in one of the functions. Based on this characteristic, in the application of sandwich panels in buildings, we should give full play to consider these characteristics and avoid the problems posed by these characteristics. Sandwich panels used for large-span industrial buildings and public buildings roof, most of them for the plate, purlin structure, sandwich panels are now produced by Sandwich plate processing equipment.
   Roof sandwich panels do not only have to bear the weight of construction to withstand the load, snow load and negative wind loads, it must be connected to the roof purlins, load transmitted beams, columns by the purlins and the like. Therefore, the connection point to the emergence of several plates and purlins; roofing Apart from sheet metal, there are several sorts of flashing accessories. Pan of water between parts, between the pan of water and the plate, between the board and the board, between the member and the surrounding buildings flashings should be linked, which resulted in a large number of connection points. These connection points above process constitutes a key color steel sandwich panel design.

Roll forming machine 6 Ways to improve stampings life!（三）

3, reasonable forging and heat treatment in the process of stamping roll forming machine operation is more important link

    In the selection of quality parts and materials while stamping, roll forming machine and material requirements for the same material of different nature reasonable forging and heat treatment, is one of the main ways to improve the durability of stamped parts. For example, when hardened, if production overheat when heated, not only will this piece too brittle, and upon cooling prone to deformation and cracking, so durability is reduced. Therefore, in the manufacture of stamping dies, we must be reasonable grasp of the heat treatment process.
Toolox material is made from pre-hardened steel straight hardened quenched and tempered steel, heat treatment is no longer required, appropriate surface treatment (such as nitrogen) on complex, high toughness Toolox matrix material, with the upper surface of the layer of high hardness, can achieve excellent Effect.

Roll forming machine 6 Ways to improve stampings life!（二）

2, the correct choice of roll forming machine stamping parts and materials

    Really use roll forming machine work process different materials have different stamping parts strength, toughness and wear resistance. The use of advanced materials under certain conditions can make to improve the durability of the good times. Therefore, in order to improve the durability of stamped parts must choose good material.

    Toolox series of material, is a kind of high toughness, high wear resistance, a pre-stress basically no hard new tool steel. And with a very high purity, very fine grain size, S, P content is very less carbide precipitation less content, and very uniform. Because of the special composition design, Toolox series material has a very excellent surface processing performance, which after Toolox44 nitriding surface hardness can reach HRC65 above, Toolox40 surface hardness can reach HRC62 or more, Toolox33 surface hardness can reach HRC58 or more, the depth of up to 1.8mm.

    Toolox series of material have the above characteristics, the material used in making the Toolox Series Stamping part has a special advantage.

1) thick steel plate (a typical case of punching a thickness of 35mm steel    plate), stainless steel, and nonferrous metal plate stamping mold, typical air conditioning fin die.

2) drawing dies, stainless steel drawing dies.

3) cold extrusion die cold extrusion 304 stainless steel, the thickness of 0.5mm or more, replace the DC53 and other materials, the effect is very good.

4) roll forming machines make use of high dimensional stability requirements of large stamping parts.

Roll forming machine 6 Ways to improve stampings life!（一）

    Roll forming machine stamping process is an essential process equipment, improve product quality, extend product life, improve production efficiency have a decisive role. However, since the stamping parts in the production process often lose their jobs wear size, it makes it difficult to meet production needs. Therefore, improving the durability of stamping dies (life) is critical.
Roll forming machine to improve the durability of the stamping method generally have the following:

1. An improved roll forming machine stamping parts of the design

    Whether to study a press roll forming machine part is designed to improve the durability of the foundation stamping. Therefore, when dealing with product design stamping molding adverse conditions and take effective measures to improve the durability of stampings, such as life design stamping holes often manifested in the red hole punch. For this type of stampings, it should be designed so that small punch to shorten its length to increase the strength, should also adopt the method of strengthening the guide sleeve to protect small punch. In addition, the stamping design, should be fully taken into account in the form of fixation methods and guide in the form of mold, punch, and determining and upper and lower rigid template center of pressure and other factors. Especially for stamping die, the selected clearance value has a great influence on durability. At design time, the gap should be a reasonable choice stampings, the gap value can not be too small, otherwise it will affect the life and durability of stamped parts. Practice has proved that, without affecting the quality of stamping the case, appropriate to enlarge the gap can greatly improve the durability of the stamping dies, sometimes even several times and several times increase.

Cold-formed steel

Roll Forming Machine - Arch
As one of the categories of cold-formed steel industry iron and steel deep processing, the process is not only cold-formed (roll) forming, but also sets the welding, punching, heat treatment and other processes of cross-sectoral and cross-industry comprehensive disciplines. Cold-formed sections welded pipe products to the production of the largest in China, has more than 6,000 million tonnes; the pressure plate, Profile has developed rapidly in our country, in the automotive, bridges, logistics, energy, machinery, and other fields It has a wide range of applications. With China's economic development, the future of cold-formed profiles in various industries in China as well as more extensive use of space, so for automation equipment and new technology, application of new technologies also have more demand.

     Hebei LiMing roll forming machinery specialized production equipment more than 20 years, with the domestic first-class production line, the products are exported to overseas markets, was well received. 2015 Dawn of the original pressure-type machine body slightly adjusted, have greatly enhanced so that in terms of aesthetics or performance.
