Abstract
The invention relates to a filling-short filling mechanism in a full-automatic power pressing machine, belonging to the technical field of power pressing machines. The filling-short filling mechanism disclosed by the invention is improved on a four-cylinder structure of a traditional filling-short filling mechanism in the full-automatic power pressing machine. The filling-short filling mechanism is mainly characterized by adopting two air cylinders, wherein two pistons are arranged on a piton rod of each air cylinder; the main piston at the upper end of the piston rod is fixedly connected with the piston rod; another secondary piston can move on the piston rod, that is, the distance between the secondary piston and the main piston can be changed from 0 to delta; the movement of the secondary piston is caused by pneumatic pressure; and the secondary piston and the main piston are respectively used as stops at the ascending positions of a cross beam. The filling-short filling mechanism disclosed by the invention has the advantages of simple structure, facilitation of reducing the manufacturing cost and strong practicability.
Description
Technical field
The present invention relates to the filling in a kind of fully automatic powder press--owe filling body, belong to the powder press technical field.
Background technology
A filling is all arranged in the fully automatic powder press--owe filling body; Or title filling--owe (mistake) filling body, its operation principle is: after the crossbeam that moves up and down of control mould (die) rises to the position (filling position) that pre-sets, treats that powder fills up matrix cavity; Crossbeam is a bit of distance, delta of microlitre more immediately; This moment the die Δ distance that also promptly rises, so the powder in the matrix cavity seems just also not fill, and also owes the degree of depth of a Δ distance and just fills.In Here it is the so-called fully automatic powder press " filling--owe filler " function.
At present domestic and international press adopts the method for pneumatic gearing and control to realize this function more.Existing conventional method has in two.
First kind is that cylinder body and the machine of two isometrical cylinder A1 and A2 connects firmly, and its piston rod and crossbeam join and be the one that can move up and down, and the screw rod of scalable height is arranged on the crossbeam.The one big cylinder B that connects firmly with fuselage is arranged above adjusting screw, and the sectional area of this cylinder is greater than cylinder A1 and A2 cross section sum.(solenoid directional control valve is not switched on, and YU=0), the B cylinder piston rod is stretched out downwards, and this piston rod is the stop of crossbeam lifting position in the epicoele air inlet of cylinder B.Because the cavity of resorption air inlet of cylinder A1 and A2, the atmospheric pressure of cavity of resorption forces crossbeam to rise through piston rod.Adjustable screw mandrel on the crossbeam is propped up by piston rod at this moment; Because the atmospheric pressure of cylinder B is greater than the upwards thrust of A1 and A2 cylinder; Risen so crossbeam just stops no longer, crossbeam promptly is in the filling position this moment, this shows that the flexible height of adjusting screw(rod) just confirmed the lifting position of crossbeam.After matrix cavity is filled up the material powder, make solenoid directional control valve get the electric YU=1 of being, reversal valve switches; Make B cylinder epicoele and atmosphere connect exhaust; The B cylinder piston rod promotes withdrawal by screw rod under A1 and A2 cylinder make progress thrust, B cylinder piston rod withdrawal stroke just is a Δ distance; This moment the crossbeam Δ distance that also just rises once more, so far " filling--owe filler " function is accomplished.
The major defect of this structure is that the sectional area of B cylinder is greater than two isometrical cylinder A1 and A2 cross section sum; Be that the B cylinder is wanted greatly; Particularly require when very big when the lifting force of A cylinder, the B cylinder can make the size of entire machine become very big, and the seal of making huge cylinder simultaneously is difficulty very also.
Second kind of structure is to develop into two cylinder B1 and B2 to the cylinder B in the said structure; Piston rod 1 two ends connect firmly the piston of A1 cylinder and B1 cylinder, during the YU=0 of electromagnetic switch air valve, below B1, B2 cylinder epicoele air inlet piston 1 and 2 are positioned in the B cylinder (promptly being positioned at retracted mode); Because A1, the air inlet always of A2 cylinder epicoele; Therefore the crossbeam that connects firmly with its cylinder body rises with cylinder body, and when cylinder body was against on the piston separately, rising just stopped.Be the filling position of crossbeam this moment; When getting electric reversal valve, magnetic valve YU switches; Make the exhaust of B cylinder cavity of resorption air inlet epicoele, this moment, piston rod 1,2 rose in the B cylinder body; Its stroke is a Δ distance; A cylinder piston also must rise same Δ distance so, under the effect of A cylinder epicoele atmospheric pressure, and A cylinder body and the crossbeam Δ distance that also just risen again from the filling position.So far realized " filling--owe filler " function.
The advantage of second kind of structure is that the vat B in first kind of structure is become two little cylinder B1, B2.Shortcoming is that structure seems complicated, and four cylinders are arranged, and has increased manufacturing cost and difficulty.
Summary of the invention
The purpose of this invention is to provide the filling in a kind of fully automatic powder press--owe filling body.Overcome above-mentioned first kind of structure and be greater than two isometrical cylinder cross section sums because of the sectional area of B cylinder, particularly require when very big when the lifting force of A cylinder, the B cylinder can make the size of entire machine become very big, and the seal of making huge cylinder simultaneously is the defective of difficulty very also; Second kind of structure is because of there being four cylinders, and it is complicated that structure seems, increased manufacturing cost and difficulty.When guaranteeing " filling--owe filler " function, implementation structure is simple, low cost of manufacture through the present invention.
The objective of the invention is to realize the filling in a kind of fully automatic powder press through following technical scheme--owe filling body, comprise two cylinders; The crossbeam that connects firmly with the cylinder body of two cylinders; Two cylinders connect source of the gas near the gas source inlet of upper end, the muffler that two cylinders connect near the exhaust outlet of lower end, the adjusting screw(rod) that comprises worm and gear that electromagnetic switch air valve and two is synchronized with the movement; It is characterized in that; The upper cover of piston rod that connects firmly with main piston in each cylinder is put auxiliary piston, and the lower end of each piston rod is fixedly connected with an end of adjusting screw(rod), in each piston rod air flue is set; The gas port of piston-rod lower end is connected with the electromagnetic switch air valve, and the gas port of each cylinder body inner piston rod is arranged between main piston and the auxiliary piston.
Auxiliary piston on the piston rod slides 0 to the Δ distance on piston rod.
The present invention is filling in existing fully automatic powder press--owe the improvement on the four cylinder structure bases of filling body.Main feature is to adopt two cylinders; Two pistons are arranged on the piston rod of each cylinder; Upper end main piston and solid rod joint, another auxiliary piston can move on piston rod, and promptly the distance between auxiliary piston and main piston can change to the Δ distance from 0; The mobile of auxiliary piston is by due to the Pneumatic pressure, and auxiliary piston and main piston are respectively as the stop of crossbeam lifting position.The present invention is simple in structure, helps reducing manufacturing cost, has very strong practicality.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Among the figure, 1 crossbeam, 2 cylinders, 3 cylinders, 4 main pistons, 5 main pistons, 6 auxiliary pistons, 7 auxiliary pistons, 8 piston rods, 9 piston rods, 10 adjusting screw(rod)s, 11 adjusting screw(rod)s, 12 electromagnetic switch air valves, 13 air flues, 14 air flues, 15 mufflers, 16 mufflers.
