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, the drive link of the powder forming machine particularly used with the cam engagement that bent axle is connected.

Background technology

Patent No. CN200520131910.X " Double-cam transmission mechanism of powder forming machine " just provide a kind of pressurization by bent axle connects, depanning double cam respectively with the press rods of band roller, go out the force transmission mechanism that tringle forms, with press central axis symmetric position on respectively have two drive links and matching used with it two to overlap parts, therefore it takies that the useful space is large, volume is large, Heavy Weight, this structure is also not suitable for installing on large-tonnage powder forming machine, otherwise the difficulty cannot transported causing volume large.

Summary of the invention

Technical problem to be solved by this invention is: the drive link providing a kind of powder forming machine, coordinate with transverse arm, its structure is simple, part is few, stable drive, efficiency are high, greatly reduce the volume and weight of powder forming machine, be convenient to produce and transport, suitable especially and large-scale powder forming machine supports the use.

The present invention's adopted technical scheme that solves the problem is: the drive link of powder forming machine, the top comprising drive link is connected with roller, drive link is gone back lower axle bed and the axle sleeve of connecting band reset cylinder, the end of drive link coordinates with transverse arm, described drive link is a push rod, the described two push rod ends with press central axis symmetry, fix a pressure compacting oil cylinder respectively, coordinated by the oil cylinder on it, the piston in oil cylinder seat and the adjusting rod be fixed on transverse arm in adjusting seat, and oil cylinder seat and adjusting seat coordinate.

Compared with prior art, the invention has the advantages that: the drive link of powder forming machine, for two push rods of symmetry, in order to replace former being arranged on and two press rods in press central axis symmetric position, scene 2 tringle, make it unite two into one, greatly reduce the quantity of drive link, reduce processing parts, easy fabrication and installation, greatly reduce the useful space taken, reduce the volume and weight of powder forming machine complete machine, be suitable for especially installing on large-scale powder forming machine, support the use, greatly reduce powder forming machine volume and be convenient to again produce, transport.

Detailed description of the invention

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

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

Each installation one reset cylinder 6 on the lower axle bed 7 of push rod both sides, lower axle bed 7 is screwed on support, and with cylinder pin 6-1 through push rod, the piston rod of two cylinders 6 is connected into entirety.

Oil cylinder 8, oil cylinder seat 10 are screwed integrally, the sliding piston 9 of joining of cylinder cavity body forms pressure compacting oil cylinder, piston and the adjusting rod 12 be fixed on transverse arm 14 in adjusting seat 11 coordinate, adjusting seat 11 is screwed on transverse arm 14, oil cylinder 8 is screwed on the lower surface of push rod, and the middle screw of adjusting seat 11 connects the adjusting rod 12 having screw thread and keyway 15.

Adjusting rod and drive sprocket wheel 13 link into an integrated entity with key, 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 metal dust that filling is enough in former, under the drive of bent axle 2, compound cam 1 is operated in bc section curve, at this moment magnetic valve 19 cuts out, and the pressure of pressure regulator valve 18 is set in certain pressure by job requirement, and compound cam 1 is pressed down past for push rod 4 by roller 3, the piston 9 that push rod 4 moves down its end touches the adjusting rod 12 promoted on transverse arm 14, drive transverse arm to move down by adjusting rod, just in former, powder moves, as shown in Figure 4.What at this moment compound cam 1 was rotated further cd edge section goes out modular curve, cd section compound cam presses to roller 3, push rod 4 is made to continue to move down, at this moment magnetic valve 19 is opened and is pressed down, and overcomes the pressure of oil cylinder 8, and the piston 9 in oil cylinder is bounced back, push rod moves down when the lower surface of its lower end oil cylinder seat 10 directly touches the upper surface of adjusting seat 11, just directly promote transverse arm and the negative template that links together with it moves down again, complete the demoulding of former, as shown in Figure 5.

When compound cam is rotated further ab edge section, magnetic valve 19 cuts out, simultaneously push rod 4 moves up reset under the effect of reset cylinder 6 piston rod and support upper and lower air cylinders, keep the contact with compound cam 1, roller 3, two oil cylinder oil inlets simultaneously on support or cylinder intake, upwards jack-up piston by piston upwards jack-up transverse arm 14, make it move up and return to original position, complete a cyclic process process, as shown in Figure 3.
