Finding Out the Results of the "Lightweight" U.S. Car
The U.S. car has always been an “iron-thick and oil-fighting tiger†in our impression. The old generation of Cruze in the domestic market is basically recognized as “hard and costlyâ€. The quality of the last generation of Lacrosse has also reached 1.7 tons. . That was because people at the time thought that the heavier the car was, the safer it was, and it turned out that this statement was not entirely correct. The heavier the car body, the higher its fuel consumption. Therefore, between the "car sinking" and the "fuel consumption," how to make the car as light as possible under the premise of ensuring safety is what every manufacturer wants to do. . Let's take a look at how the U.S. car is "lightweight". The three generic brands of American cars, Chevrolet, Buick, and Cadillac, are all sold globally. Therefore, it is not enough to just fit Americans' tastes but also to ensure better sales. Its Mai Rui Bao is the use of the latest high-strength steel, not only to reduce the thickness of the steel structure of the body structure, but also in the case of the original car body lengthened 58mm under the circumstances, so that the vehicle's curb weight is reduced by 54kg. As a luxury brand competing with ABB, Cadillac is not a local identity. The CT6 is to be aligned with the 7 Series. The actual wheelbase is 3.1 meters between the 5 Series and the 7 Series. However, the starting quality of the Starter Edition is only over 1.6 tons and is 100 kg lighter than the 5 Series. Ford's engineers are even more powerful, and they have started the brain hole model and studied how to "lightweight" materials. It is more daring to assume how to use coconut as a seat filler and soy as a headrest material. Mondeo's front and rear doors also use kenaf fiber reinforced materials, which are 30% lower than traditional chemical materials. Naturally, “lightweight†is no exception. It can be imagined that, despite the current pursuit of "lightweight" vehicle equipment, although the old United States is not more advanced than Europe, Japan and other countries, its "lightweight" actions and achievements are worthy of our admiration. of.
Classification of tablet press: Models can be divided into single punch tablet press, rotary tablet press, sub-high speed rotary tablet press, automatic high speed tablet press and rotary core tablet press.
The sheet shape pressed by the tablet press is initially flat circular, and later developed into shallow circular arc and deep circular arc on both sides, which is for the need of coating. With the development of special-shaped tablet press, oval, triangle, oblong, square, diamond, circular ring tablets followed. In addition, with the continuous development of preparations, due to the requirements of compound preparations and timed release preparations, special tablets such as double layer, triple layer and core coating are made, which need to be completed on special tablet press.
Rotary tablet press is a machine which is made of several pairs of die distributed on the turntable to make a circular lifting movement according to a certain track and press the granular material into tablet through the press wheel. And the stamping rod with the rotary table rotating speed ≥60m/min line press is called high-speed rotary tablet press, this high-speed rotary tablet press has a forced feeding mechanism, the machine is controlled by PLC, has the automatic adjustment of pressure, control the weight of the piece, eliminate the waste piece, print data, display fault shutdown and other functions, in addition to the control of the weight difference within a certain range, Quality problems such as missing Angle and loose lobe can be automatically identified and eliminated.
With the development of market demand, the scope of application of tablet press is more and more wide, no longer simply limited to the suppression of Chinese and Western medicine tablets, more widely suppressed health food, veterinary medicine tablets, chemical tablets: such as mothballs, washing blocks, smurf blocks, art powder, pesticide tablets, food tablets: chicken essence block, isatis root block, divine Qu tea block, compressed biscuits.
