Square box table

Square box table bearing requirements: square box bearing means to me to bear the weight per unit area, the deflection of square box. For ease of understanding, we can be seen to me put away the workpiece, without affecting the normal use of the situation, to me are able to withstand the pressure. For example: 2000mm × 4000mm square box that can be placed a weight of 64 tons of artifacts, this square box bearing, we can simply be seen as: 64 tons ÷ (2 m × 4 m) = 8 tons / per square meter. Of course, to me the bearer and his actual design and the actual production process there are relatively close relationship. When customers buy side box frequently and national standards have access to part of the parameters. We know that to me is based on the "People's Republic of China Machinery Industry Standard" JB / T 7974-2001 design, practical applications but also consider the actual needs. So in the design of the square box can be the height of the face, ribs and so do the reasonable changes to suit the actual needs of the square box. The other box selection of materials, but also with the economic development constantly changing, and now HT150 HT200 from the sixties and seventies, and even HT250, some users also use the HT300, which indicates that companies have economy the strength, people pay more attention to the quality of the square box. However, in the selection of the material side of the box, we recommend that you choose HT200 is enough, after all, previous experience and business standards (the original has been using the HT150 material) can learn from, square box with HT250, HT300 little economic waste . The weight of the finished square box and some can reach 50 tons, so lifting is an unavoidable part of square boxes can be assured of, to me from casting blank to finished product use to go through several lifting and transport, in the lifting process to consider some unexpected situation may occur will occur in advance to prepare, surrounded by square boxes are designed to hatch, according to me when lifting step requires the operator before they can transported. So it can guarantee to me without distortion, be sure to use the time to me without problems. Generally square box of long life, as long as the correct way to use and protect release, precision square box face can be kept for more than 2 years, you can recover by scraping process when debugging or reduce precision square box, square box itself life can reach 50 - 100 years, so, in the course of use to me not to pay attention to moisture, corrosion, under high and low temperature environments and storage, so that it can extend the life of the square box, to ensure quality of work. Other tank design drawings and the actual appearance of size there will be some errors, such as length, width and height diagonal boxes, etc., are generally between ± 0.02 (a or b), square box height requirements: 630 × 630 The square box at from 220 至 140; 1000 × 1000 至 are 800 × 800 cast iron boxes height between 300 and 400; 1600 × 1000 or more than 400 square box height. Square boxes for a variety of inspection, such as the dimensional accuracy of precision measurement reference plane, inspection of measuring a variety of machine tools, inspection of parts, line deviation and make precision crossed, to me is machine tools, machinery manufacturing, electronics production and other 20 kinds of industries indispensable product. Square box is crossed, measuring, welding, tooling process is absolutely essential table, square box can also do mechanical test stand, and so on. Square box production processes are generally strictly a "People's Republic of China Machinery Industry Standard" JB / T 7974-2000 processing and production. But sometimes even local conditions, to be flexible in design. In the national standard and enterprise standards and the use of square box square box square box requirements differ, it can be specially designed according to the actual needs of the other boxes. Square box design philosophy must be based on the lowest cost to achieve the best results, but also to achieve the best results the production and use of the principle of mutual benefit to both sides. Usually by use of the square box are classified according to purpose of the square box classification is: When do the test called the test square box, crossed square box called when crossed, call me when assembling assembly called party when drawing a line drawing lines box, called when welding welding square box, square box when called tooling tooling, called vibration when the vibration Experiment square box, called welded square boxes, etc. during welding.
