The specific embodiment
Below in conjunction with accompanying drawing the utility model is done further detailed explanation:
Realize being connected with alignment pin 3 through establishing piston alignment pin 4 between the utility model top shoe ball screw guiding mechanism 1 and the top shoe air cylinder board 53.
1, top shoe ball screw guiding mechanism 1:
This mechanism: (1), the amount of pressurization to upper punch when being used to suppress are adjusted, i.e. adjustment comprises the top shoe mechanism of top shoe 2; (2) drive top shoe connecting rod 12 by driving crank 11, accomplish the pressurization pressing process of top shoe 2; Pass through the shut height of this mechanism's scalable machine of adjustment when (3) machine assembles; Its process is following: rotate and drive worm gear 14 rotations through driven by motor worm screw 15; Ball screw 13 is by bulb spline circle 16 splines; It can only be moved up and down under the drive of worm gear 14, move up and down, accomplish adjustment process thereby change plate 17 drive top shoe mechanisms by bulb.
2, hydraulic die cushion pressure display mechanism 5:
Operational forces when this mechanism suppresses whole top shoe briquetting machine is monitored in real time, and its principle is an injection pressure oil in the oil pocket between hydraulic die cushion oil cylinder piston 52 and top shoe air cylinder board 53, and this oil pocket is connected with pressure sensor; The pressure that upper junction plate 54 is born from the upper punch on the mould bases; Reach the hydraulic die cushion oil pocket through upper cylinder piston 51 and hydraulic die cushion oil cylinder piston 52, show in real time on touch-screen through PLC again, when another function of this mechanism is the vexed car of machine pressing; Promptly working as upper punch is stuck in former; Can bleed off the pressure oil in the hydraulic die cushion, top unclamped, so that handle upper punch or drive anti-car.
3, protection mould emptier 6:
Its operation principle is that top shoe mechanism is behind downward end-of-job under driving crank 11 effects; Upwards make drawback movement; Machine is done demoulding campaign after also promptly suppressing end-of-job, just goods is deviate from the cavity impression on the mould bases, and this process is that former moves downward; And bottom punch is motionless, and then goods are ejected die cavity.For prevent that goods from ftractureing in deviating from process; When upper punch moves on top shoe 2 backhauls, the ventilation of upper cylinder piston 51 upper ends, upper cylinder piston 51 moves downward and drives upper punch and move downward; Although top shoe 2 drives upper punch and moves last; But because the piston rod of upper cylinder piston 51 is moving down, the relative position that makes upper punch be pressed on the goods does not change, and upper punch is compressed on the goods with a constant force all the time; Deviate from die cavity fully until goods, reach the purpose of the protection demoulding.Its course of work is: driving crank 11 drives top shoe 2 and moves downward end, move on the top shoe 2, and demoulding action beginning, the ventilation of upper cylinder piston 51 upper ends moves downward it, and the beginning angle is that beginning finishes to 280 degree about 170 degree; Finish back upper cylinder piston 51 lower ends ventilation, piston reset is up, and an impulse stroke finishes.For preventing that being reset to terminal point produces bump, increase upper cylinder cushion pad 56 here, to reach the purpose of the buffering that resets; In addition for making upper cylinder piston 51 descending reliable and stable, accurate positioning shaping-orientation post guiding mechanisms; Be that upper junction plate 54 connects upper cylinder pistons 51 and by both sides guide pillar 61 guiding; In guide pillar 61 fairleads 62, move up and down, with guiding and anti-rotation upper cylinder piston 51 utmost points and the corresponding construction part that is connected thereof.
4, synchronously the compacting and final pressing mechanism 7:
The operation principle of this mechanism is to come execution through a pair of synchronous compacting oil cylinder 71 that is connected on the top shoe air cylinder board 53; Mechanism moves downwards by top shoe; Driving synchronously, compacting oil cylinder 71 moves down; To being pressed onto on the compacting adjusting screw(rod) 72, driving negative template 74 through supporting seat 73 and force to move down, to reach the upwards purpose of pressurization of bottom punch; The size of pressing stroke is regulated (in fact being exactly the adjusting to the goods volume under pressure) by compacting adjusting screw(rod) 72 synchronously; When negative template 74 is stopped when motionless by following block, top shoe 2 continues to move downward, and suppresses oil cylinder 71 overflow valve overflows synchronously; The oil cylinder piston bar is withdrawn along with moving down of upper punch; Finish fully until last pressurization, promptly top shoe 2 strokes finish fully, promptly for the 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 by driving crank 11 and move down; Upper punch gets into die cavity and powder is pressurizeed first; Then synchronous compacting oil cylinder 71 is pushed down compacting adjusting screw(rod) 72 and is driven negative template 74 and moves to certain stroke to pressed, accomplishes pressure process for the second time; This moment, negative template 74 supported blocks stopped motionless; Upper punch continues to move down with top shoe 2, suppresses oil cylinder 71 overflows synchronously, and piston resets along with moving down of upper punch and returns; Upper punch continues to move downward until capable 2 journeys of top shoe and finishes, and accomplishes final pressure process.
5, powder compaction is moved powder mechanism 8:
The purpose that designs this structure is to go up outer step design for being shaped; This mechanism makes the density of outer step be able to guarantee; Comprise moving powder cylinder 81 and being connected to move and move the powder extension bar on the powder cylinder 81, move powder extension bar bottom and connect and move powder bar briquetting through moving powder bar contiguous block 83 through locking nut 82; Its principle is that utilization moves powder cylinder 81 and top shoe 2 together moves down, and next that promotes to be contained on the float plate dashed the position that together moves down into the block location, and float plate is stopped by block, and top shoe 2 continues to press down, and moves the powder cylinder piston rod and withdraws, and outer step is pressed shaping.The design demand of moving powder mechanism is relevant with the dress powder form of former, and the dress powder of outer step is many in the middle of requiring, few up and down, and actual dress powder structure can only realize that upper end dress powder is many; Step broad in the middle is shaped needs more powder, comes press forming in the middle of then need the upper end powder being moved to, and the utility model is at first through moving the characteristics that powder bar briquetting 84 contacts with former; Make former receive a downward power but keep motionless; It receives powder to its downward frictional resistance, and powder receives the former inwall to its downward power conversely, and it is moved downward; Thereby powder is flowed in the middle of the former, thereby guarantee the Forming Quality of goods.
