Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is further detailed explanation:
1, top shoe ball screw guiding mechanism 1:
This mechanism: (1), for suppressing time the amount of pressurization of upper punch is adjusted, namely adjustment comprises the top shoe mechanism of top shoe 2; (2) drive top shoe connecting rod 12 by driving crank 11, complete the pressurization pressing process of top shoe 2; (3) shut height of this mechanism of adjustment adjustable machine is passed through during machine assembling, its process is as follows: rotated by driven by motor worm screw 15 and drive worm gear 14 to rotate, ball screw 13 is by bulb spline circle 16 spline, make it can only move up and down under the drive of worm gear 14, thus change plate 17 by bulb and drive top shoe mechanism to move up and down, complete adjustment process.
2, hydraulic die cushion pressure display organ 5:
This mechanism monitors in real time to operational forces during whole top shoe briquetting machine compacting, its principle is injection pressure oil in the oil pocket between hydraulic cushion cylinder piston 52 and top shoe air cylinder board 53, this oil pocket is connected with pressure sensor, the pressure from the upper punch on mould bases that upper junction plate 54 bears, hydraulic die cushion oil pocket is reached by upper cylinder piston 51 and hydraulic cushion cylinder piston 52, shown in real time on the touchscreen by PLC again, when another function of this mechanism is machine pressing vexed car, namely when upper punch is stuck in former, the pressure oil in hydraulic die cushion can be bled off, top is unclamped, so that process upper punch or drive anti-car, by establishing piston alignment pin 4 and alignment pin 3 to realize being connected between top shoe ball screw guiding mechanism 1 of the present invention and top shoe air cylinder board 53.
3, mould emptier 6 is protected:
Its operation principle is top shoe mechanism under driving crank 11 acts on downwards after end-of-job, upwards make drawback movement, also after namely suppressing end-of-job, stripping movement made by machine, namely goods are deviate from the cavity impression on mould bases, this process is that former moves downward, and bottom punch is motionless, then goods are ejected die cavity.Deviating from process to ftracture for preventing goods; at upper punch with when top shoe 2 backhaul moves; ventilate in upper cylinder piston 51 upper end; upper cylinder piston 51 moves downward and drives upper punch to move downward; although top shoe 2 drives upper punch to move upper; but because the piston rod of upper cylinder piston 51 is moving down; the relative position that upper punch is pressed on goods does not change; upper punch can be made like this to be compressed on goods with a constant force all the time; until goods deviate from die cavity completely, reach the object of the protection demoulding.Its course of work is: driving crank 11 drives top shoe 2 to move downward end, and top shoe 2 moves, and stripping action starts, and the ventilation of upper cylinder piston 51 upper end makes it move downward, and beginning angle is about 170 degree and starts to about 280 degree end; Upper cylinder piston 51 lower end ventilation after terminating, piston reset is up, and an impulse stroke terminates.Producing shock for preventing being reset to terminal, increasing upper cylinder cushion pad 56 herein, to reach the object of the buffering that resets; In addition for making descending reliable and stable, the accurate positioning shaping-orientation post guiding mechanism of upper cylinder piston 51, namely upper junction plate 54 connects upper cylinder piston 51 and is led by both sides guide pillar 61, move up and down in guide pillar 61 fairlead 62, with the corresponding construction part led with anti-rotation upper cylinder piston 51 pole and connection thereof.
4, synchronous compacting and final pressing mechanism 7:
The operation principle of this mechanism carrys out execution by a pair synchronous pressure liquefaction cylinder 71 be connected on top shoe air cylinder board 53, by the downward action of top shoe mechanism, synchronous pressure liquefaction cylinder 71 is driven to move down, to being pressed onto on compacting adjusting screw(rod) 72, negative template 74 is driven to force to move down, to reach the object that bottom punch upwards pressurizes by supporting seat 73; The size of synchronous pressing stroke regulates (being in fact exactly the adjustment to goods volume under pressure) by suppressing adjusting screw(rod) 72; When negative template 74 stops motionless by lower block, top shoe 2 continues to move downward, the overflow of synchronous pressure liquefaction cylinder 71 overflow valve, cylinder piston rod is retracted along with moving down of upper punch, until upper pressurization terminates completely, namely top shoe 2 stroke terminates completely, namely third time upper punch to the pressurization of goods, its objective is and improve goods top density, improve the uniformity of extrudate density; Its sequence of movement is: drive top shoe 2 to move down by driving crank 11, upper punch enters die cavity and pressurizes first to powder, then synchronous pressure liquefaction cylinder 71 is pushed down compacting adjusting screw(rod) 72 and is driven negative template 74 compacting downwards to move to certain stroke, completes second time pressure process; Now negative template 74 is stopped motionless by support limit stop, upper punch continues to move down with top shoe 2, the overflow of synchronous pressure liquefaction cylinder 71, and piston resets along with moving down of upper punch and returns, upper punch continues to move downward until top shoe stroke terminates, and completes final pressure process.
5, powder compaction Yi Fen mechanism 8:
The object designing this structure is the upper outside step design that is shaped, this mechanism makes the density of outer step be ensured, comprise moving powder cylinder 81 and being connected to move by locking nut 82 and powder cylinder 81 moves powder extension bar, move powder extension bar bottom and connect move powder bar briquetting by moving powder bar contiguous block 83; Its principle is that utilization moves powder cylinder 81 and top shoe 2 together moves down, and promote the position that next punching be contained in float plate together moves down into block location, float plate is stopped by block, and top shoe 2 continues to press down, and move the retraction of powder cylinder piston rod, outer step is pressed shaping.The design of Yi Fen mechanism needs the dress powder form with former relevant, the dress powder of outer step requires that centre is many, few up and down, and actual dress powder structure can only to realize upper end dress powder many, step broad in the middle is shaped and needs more powder, then needing upper end powder to be moved to centre comes compressing, the present invention is first by moving the feature that powder bar briquetting 84 contacts with former, former is made to be subject to a downward power but to keep motionless, it is subject to powder to its downward frictional resistance, powder is subject to former inwall to its downward power conversely, it is made to move downward, thus make powder stream in the middle of former, thus ensure the Forming Quality of goods.
