Every rush press of the upper mould, the working procedure has twice rushing press to the pug adobe, just as after the upper mould press the adobe to the true place, the upper mould rise 10mm, and made the pug adobe get the fill exit air, then the upper mould press the adobe to the true place, and back to the highest position, so the mould has the longer life, and the quantity of the pressed products is good. This machine collocated one set of lubricate system, when the machine running, it can add oil lubricate automatism to all the bear weight bearing and the transmission gear wheel structure working orbit and so on Two Main technical parameter No item unit number 1 general weight press KN 600 2 working plate working number set 6 3 working plate turning speed Turn/min 2. 5 4 working capacity piece/min 15 5 motor power KW 5. 5 6 lubricate pump flow rate ML/min 500 7 working plate size ㎜ 632 450 8 upper mould stroke ㎜ 150 9 the biggest higher of the open and closed ㎜ 442 10 the least closed height ㎜ 292 11 outside size ㎜ (L W H) 17232 1100 2463 12 whole set weight ㎏ 5200 Three Structure summarize This machine is mainly made up by the right and left machine body, bottom connect bin, top machine box annex, lubricate sit, six way turn wheel, belt wheel, gear wheel structure, Geneva wheel structure, tu wheel structure, lubricate pump, oil way system and the electrical controlling part. The upper rushing press working procedure of this machine: from the motor and though the belt wheel, and bring along with the input axis, and then though the little gear wheel, big gear wheel, bring along with the upper axis, though one set of tu wheel structure bring along with the lubricate sit which installed upper mould working up and down, and realize the press brick. The turner of the working plate was realized by the wheel group of the upper axis, driving dial wheel, dialing the Geneva wheel of the six turning wheel axis. On the two sides of the upper axis, it installed one set of back tu wheel which is installed at the same axis and the press tu wheel, though the locating lever and the locating tray to realize the true locate of the working position. In the right machine box was installed lubricate pump, when the machine though, the oil pipe was transported the lubricate oil to every attrition working position. The customer should install the automatism installing material machine and the removing brick machine. The pug adobe which is extruding by the extruder, though the cutter cut to the true length, and though the roller transporter transported to the installing material fight, though the installing material ware transported to the down mould according to the established procedure, the brick adobe which was turning position on the working plate, though the vacuum cupules imbibitions of the removing brick machine, and turn putting on the brick entrust of the transported line. The installing material fight was made up by the machine fight, drive roller group, swing rise and down fight, installing material ware, motor, cylinder, pneumatic valve and so on. The removing brick adobe machine was made up by th
