預(yù)制橋梁防撞墻鋼模具—橋梁防撞墻鋼模具  河北宏旭

預(yù)制橋梁防撞墻鋼模具的原材料主要選自優(yōu)質(zhì)的混凝土做主要材料，經(jīng)過攪拌后的混凝土中會(huì)存在大量的空氣氣泡，所以在給預(yù)制橋梁防撞墻鋼模具進(jìn)行澆筑后，需要對(duì)混凝土進(jìn)行震動(dòng)，這樣的操作方式是為了讓混凝土中的空氣有效的排出，提高混凝土的密度，加大堅(jiān)固性。所以在進(jìn)行給混凝土震動(dòng)的時(shí)候，需要將震動(dòng)棒放入混凝土中間位置，然后操作2-4次左右進(jìn)行震動(dòng)，這樣能有效的將空氣排出，提高質(zhì)量。預(yù)制橋梁防撞墻鋼模具在經(jīng)過震動(dòng)后能提高性能，常常使用在高速中央的地帶，主要起到隔離的作用，而且現(xiàn)在的設(shè)計(jì)將隔離帶預(yù)制件的外觀上進(jìn)行了洞口的設(shè)計(jì)，也是為了讓進(jìn)行擺放還有搬運(yùn)的時(shí)候，能提高質(zhì)量以及速度。在預(yù)制橋梁防撞墻鋼模具的設(shè)計(jì)過程中要注意的就是模具的質(zhì)料的合理利用,沖裁件的實(shí)際面積與所用板料面積的百分比,這是是衡量合理利用質(zhì)料的經(jīng)濟(jì)性指標(biāo)。在設(shè)計(jì)模具的過程中一定要在掌握提高質(zhì)料利用率的要領(lǐng),沖裁所孕育產(chǎn)生的廢料,布局廢料和工藝廢料。是由模具本身的形狀決定的工藝廢料取決于搭邊與余量的大小,也取決于排樣要領(lǐng)與沖壓要領(lǐng)。

The raw material of the steel mould of the prefabricated bridge anti-collision wall is mainly selected from the high-quality concrete as the main material. After mixing, there will be a lot of air bubbles in the concrete. Therefore, after pouring the steel mould of the prefabricated bridge anti-collision wall, it is necessary to vibrate the concrete. Such operation mode is to effectively discharge the air in the concrete and improve the density of the concrete Great firmness. Therefore, when vibrating the concrete, it is necessary to put the vibrator in the middle of the concrete, and then operate it for 2-4 times to vibrate, so as to effectively exhaust the air and improve the quality. The steel mould of the prefabricated bridge anti-collision wall can improve the performance after the vibration, and is often used in the high-speed central area, which mainly plays the role of isolation. In the current design, the appearance of the prefabricated parts of the isolation belt is designed for the opening, which is also to improve the quality and speed when they are placed and transported. In the design process of the steel mould for the prefabricated bridge anti-collision wall, we should pay attention to the rational use of the material of the mould, the percentage of the actual area of the blanking part and the area of the plate used, which is the economic index to measure the rational use of the material. In the process of mold design, we must master the key to improve the utilization rate of materials, the waste generated by blanking, layout waste and process waste. It is determined by the shape of the die itself that the process waste depends on the size of the lap and allowance, as well as the layout and stamping essentials.
