Description
Technical field
The utility model relates to the filling of a kind of fully automatic powder make-up machine and crosses the amount of owing duplex cylinder mechanism, belongs to powder metallurgical technology.
Background technology
For the dress powder to powder in the product molding process carries out better controlling, to form good goods; The operation of existing technology cylinder control commonly used former, the normal cylinder structure that adopts of existing controlling organization, former and associated components regular meeting receive force unbalance in control procedure; Run-off the straight when causing adorning powder with compacting; Influence the Forming Quality of goods, and its cylinder diameter of a cylinder structure is big, the accuracy of manufacture and installation accuracy are had relatively high expectations; Production cost is higher, and institute takes up space bigger.
The utility model content
The utility model is to above-mentioned defective; Purpose is to provide a kind of employing twin-tub structure; Make each associated components stress balance in dress powder, pressing process, thereby the amount of owing duplex cylinder mechanism is crossed in the fully automatic powder make-up machine filling that makes the goods that are pressed into can reach good quality.
The technical scheme that adopts of the utility model is for this reason: the utility model comprises that the duplex cylinder comprises the filling restoring cylinder and is arranged on the mistake amount of the owing cylinder of filling restoring cylinder bottom through piston rod; The filling restoring cylinder connects with the crossbeam that is connected with former through connector; The crossbeam middle part is provided with the knockout pin that is connected with it, and said duplex cylinder is symmetricly set on said crossbeam both sides;
Said connection filling restoring cylinder, the piston rod of crossing the amount of owing cylinder are connected with filling adjusting mechanism through filling adjustment screw rod, and filling restoring cylinder, the mistake amount of owing cylinder are provided with the control device of controlling the gas airintake direction.
Said former filling position is provided with the filling checkout gear.
Said control device is an Electromagnetic Control.
The utility model has the advantages that: 1) the utility model adopts the twin-tub structure, has reduced cylinder diameter, is convenient to make, and has improved the balance of action simultaneously; 2) the utility model changes the mode of traditional cylinder piston rod motion, adopts the mode of movement of cylinder block, and piston rod is connected the purpose that plays the adjustment packed height with filling adjustment screw rod simultaneously, and more traditional structural adjustment is more convenient and accurate; 3) the single cylinder structure that the twin-tub structure of the utility model is more traditional is more compact, has reduced taking of space; 4) the utility model has further increased the filling measuring ability, and operating personnel can be adjusted mechanism timely, makes it can guarantee to be in correct position, to guarantee the Forming Quality of goods.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the control chart of the utility model.
Among the figure 1 for filling restoring cylinder, 2 be the amount of owing cylinder, 3 for piston rod, 4 for filling adjustment screw rod, 5 be that crossbeam, 6 is that filling sense switch Xk1,7 is a knockout pin.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is made further explanation:
1, filling reset function: filling is crossed the amount of owing duplex cylinder and is connected firmly together through support and crossbeam 5, and crossbeam 5 connects firmly with former, so the position of crossbeam 5 promptly determines the filling amount of former;
Under the normality; Filling restoring cylinder 1 epicoele normal open gas, cross the ventilation of the amount of owing cylinder 2 epicoeles, crossbeam 5 is in filling position (seeing Fig. 1 position 2), and press begins compacting after accomplishing the action of dress powder; Compacting finishes back knockout pin 6 forces to press down arrival demoulding position (seeing Fig. 1 position 1) with crossbeam 5 together with former; Filling cylinder piston is motionless in this process, and the filling cylinder body moves down together with crossbeam 5, and the epicoele air of filling restoring cylinder 5 is compressed.Former moves on press completion pusher action back knockout pin 7 resets on demoulding position.Crossbeam 5 resets to the filling position together with former under the compressed-air actuated effect of filling restoring cylinder 1 epicoele, press is accomplished dress powder action continued and suppressed action next time.The dress powder height of former is regulated by filling adjusting mechanism, regulates the height up and down that screw rod 4 is adjusted in filling through worm couple, drives 3 rise and fall of duplex cylinder piston rod, thereby reaches the purpose of adjustment packed height, and piston rod 3 plays the spacing effect of filling.
2, cross the amount of owing dress powder function
The so-called dress powder of crossing is meant being unkitted powder and owes that on the basis of setting packed height h, coil YU6 gets; The two-position four way change valve action is crossed the 2 cavity of resorption air inlets of the amount of owing cylinder, the epicoele exhaust; Because filling restoring cylinder 1 epicoele is ventilated all the time and pushed down piston rod 3, the crossbeam 5 that therefore links to each other with filling restoring cylinder 1 will rise a bit of apart from △ y (crossing the stroke of the amount of owing cylinder) together with former, and the material boots are accomplished the filling action; The filling amount of this moment is h+ △ y, the material boots still on the negative impression face, coil YU6 dead electricity; The 2 epicoele air inlets of the amount of owing cylinder, cavity of resorption exhaust are crossed in two-position four way change valve action, and crossbeam 5 is together with the former △ y distance that descends rapidly; Expect that then boots return, actual work loading height still be h, but adorn more closely knit;
What is called owes to adorn powder, is accomplish dress powder height h action, and upper punch is pressed into before the negative impression; Coil YU6 gets electric, and the 2 cavity of resorption air inlets of the amount of owing cylinder are crossed in the two-position four way change valve action; The epicoele exhaust, the former of filling powder moves up a bit of apart from △ y (powder is motionless), makes powder be positioned at △ y distance under the die face; Usually △ y is a steady state value, is called the charging stroke.
3, former equilibrium function
Finish in this time period before the drop-down demoulding from compacting, former receive filling restoring cylinder 1 upwards the effect of thrust may move up down, be called former and rebound; Mould come-up in also claiming, this action may make pressed compact produce demoulding crackle, in order to prevent this phenomenon; In before compacting finishes, finishing before between this section to the demoulding, coil YU5 gets electric, and two position three way directional control valve makes the also air inlet of cavity of resorption of filling restoring cylinder 1; Air pressure with balance filling restoring cylinder 1 epicoele; Pressurizing valve in this gas circuit of scalable makes former during this period of time keep balance, prevents that pressed compact from producing demoulding crackle.
4, filling measuring ability
After the demoulding finished, filling restoring cylinder 1 was reset to the filling position with former, just triggered filling sense switch XK16 this moment, and press continues operation, does not reset to the filling position like former, does not trigger filling sense switch XK16, with stopping alarm.
