Abstract

The invention provides a transmission rod of a powder forming machine. Rolling wheels are connected to the top ends of the transmission rod; lower shaft seats with resetting air cylinders and shaft sleeves are further connected to the transmission rod; the tail end of the transmission rod is matched with a cross arm; the transmission rod is provided with ejecting rod; pressure pressing oil cylinders are respectively fixed at the tail ends of the two ejecting rods symmetrical with the central axis of a press, and matched with regulating rods in regulating seats fixed on the cross arm through oil cylinders on the pressure pressing oil cylinders and pistons in oil cylinder seats; the oil cylinder seats are matched with the regulating seats; and the oil cylinders are further connected with electromagnetic valves and pressure regulating valves. Two pressure rods and two demoulding rods originally mounted in the positions symmetrical with the center axis of the press are replaced by using the two symmetrical ejecting rods, so that the pressure rods and the demoulding rods are integrated, the number of the transmission rod is greatly reduced, parts to be processed are reduced, the manufacturing and the mounting are easy, the occupied effective space is greatly reduced, the volume and the weight of the whole powder forming machine are decreased, and the production and the transportation are facilitated. The transmission rod is particularly suitable for being mounted on and matched with a large-scale powder forming machine for use.

Description

The drive link of powder forming machine

Technical field

The present invention relates to the vitals on a kind of powder forming machine, particularly with bent axle on the drive link of the powder forming machine that is used of the cam that is connected.

Background technology

Patent No. CN200520131910.X " the double cam force transmission mechanism of powder forming machine " just provide a kind of by the pressurization that connects on the bent axle, depanning double cam respectively with the band roller press rods, go out the force transmission mechanism that tringle constitutes; With press central axis symmetric position on respectively have two drive links and matching used with it two to overlap parts; So it takies, and the useful space is big, volume big, Heavy Weight; This structure does not also suit on the large-tonnage powder forming machine, to install, otherwise the difficulty that will cause volume can't transport greatly.

Summary of the invention

Technical problem to be solved by this invention is: the drive link that a kind of powder forming machine is provided; Cooperate with transverse arm; It is simple in structure, part is few, and stable drive, efficient are high, has significantly reduced the volume and weight of powder forming machine; Be convenient to produce and transportation the suitable especially and supporting use of large-scale powder forming machine.

The present invention addresses the above problem the technical scheme that is adopted: the drive link of powder forming machine; The top that comprises drive link is connected with roller; Go back the following axle bed and the axle sleeve of connecting band reset cylinder on the drive link, the end of drive link cooperates with transverse arm, and said drive link is a push rod; Said two push rods with press central axis symmetry are terminal; Fixing respectively pressure compacting oil cylinder cooperates through the oil cylinder on it, the piston in the oil cylinder seat and the adjusting rod that is fixed in the transverse arm rise bed rearrangement, and oil cylinder seat and the cooperation of adjustment seat.

Compared with prior art, the invention has the advantages that: the drive link of powder forming machine is two push rods of symmetry; In order to replace former be installed in press central axis symmetric position on two press rods, scene 2 tringle, it is united two into one, significantly reduce the quantity of drive link; Reduce processing parts, be prone to fabrication and installation, significantly reduce the useful space that takies; Dwindle the volume and weight of powder forming machine complete machine; Suit especially on large-scale powder forming machine, to install, supporting use is dwindled the powder forming machine volume greatly and is convenient to again produce, transport.

The specific embodiment

Below in conjunction with accompanying drawing embodiments of the invention are further described.

Fluted connection one roller 3 in the top of push rod 4, roller two sides first circular arc rest block 3-1 is placed in the arc groove that the push rod two side is complementary, and the upper end cunning fits in the axle sleeve 5, and axle sleeve 5 is screwed on the both sides of frame, is convenient to the location of push rod.

One reset cylinder 6 respectively is installed on the following axle bed 7 of push rod both sides, and following axle bed 7 is screwed on support, and passes push rod with cylinder pin 6-1, and the piston rod of two cylinders 6 is connected into integral body.

Oil cylinder 8, oil cylinder seat 10 are screwed whole; Cylinder cavity body cunning is joined piston 9 and is constituted pressure compacting oil cylinder; Piston cooperates with the adjusting rods 12 that are fixed in the transverse arm 14 rise bed rearrangements 11; Adjustment seat 11 is screwed on transverse arm 14, and oil cylinder 8 is screwed on the lower surface of push rod, and screw connects the adjusting rod 12 that screw thread and keyway 15 are arranged in the middle of the adjustment seat 11.

Adjusting rod and drive sprocket wheel 13 usefulness keys link into an integrated entity, and only can move up and down at the effect lower dolly bar of sprocket wheel.

Oil cylinder 8 is connected with pressure regulator valve 18, magnetic valve 19.

During use, start powder forming machine, the enough metal dusts of filling in former; Under the drive of bent axle 2, compound cam 1 is operated in bc section curve, and at this moment magnetic valve 19 cuts out; The pressure of pressure regulator valve 18 is set in certain pressure by job requirement, and with push rod 4 pressed downward, push rod 4 moves down its terminal piston 9 and touches the adjusting rod 12 that promotes on the transverse arm 14 compound cam 1 through roller 3; Drive transverse arm by adjusting rod and move down, just powder moves in the former, and is as shown in Figure 4.At this moment compound cam 1 is rotated further the modular curve that of cd edge section, and cd section compound cam is pressed to roller 3, makes push rod 4 continue to move down; At this moment magnetic valve 19 is opened and is pressed down, and overcomes the pressure of oil cylinder 8, makes piston 9 retractions in the oil cylinder; Push rod moves down when the lower surface of its lower end oil cylinder seat 10 directly touches the upper surface of adjustment seat 11; The negative template that just directly promotes transverse arm and link together with it moves down once more, accomplishes the demoulding of former, and is as shown in Figure 5.

Magnetic valve 19 cuts out when compound cam is rotated further the ab edge section; Push rod 4 moves up under the effect of reset cylinder 6 piston rods and support upper and lower air cylinders and resets simultaneously, and maintenance contacts with compound cam 1, roller 3, simultaneously two oil cylinder oil-feed or cylinder intakes on support; Jack-up piston and upwards by the piston jack-up transverse arm 14 that makes progress; It is moved up return to original position, accomplish one time the cyclic process process, as shown in Figure 3.
