Abstract

The utility model relates to a carbon-graphite product forming machine. When heavy-in-section manufactured products are needed to be processed by the prior congener forming machines including big tonnage hydraulic forming machines and gravitation vibrating machines; the former is big volume and high cost; the latter is undergrade processing. The lower part of the utility model is provided with a vertical-direction vibration device; the upper part of the utility model adopts a hydraulic forming mechanism and is provided with an evacuating device. The pressure conducting components are arranged on the upper part of the utility model, which can link the hydrocylinder on the upper part with the moulds pressured by the hydrocylinder as one piece in vertical direction. Thus vibration device on the lower part does not endure the pressure of the press head. The utility model has the advantages of small volume, simple structure, low cost, high density and good quality of the products processed.

Description

The carbon graphite product molding machine

The utility model belongs to the make-up machine of producing carbon graphite goods blank.

In producing charcoal element and graphite product make-up machine, produce heavy in section goods at present, promptly need the large-tonnage hydraulic press more than 1000 tons and even 3500 tons, its complex structure, cost height.Though vibrating forming machine is simple in structure, cost is low, can produce heavy in section goods, but inhomogeneous with its product density of producing, mechanical strength is low, the quality instability.

It is little that the utility model aims to provide a kind of volume, simple in structure, and cost is low, can improve the make-up machine of the carbon graphite goods of converted products quality.

For achieving the above object, the utility model adopts following structure, figure describes in conjunction with the embodiments, it comprises workbench 4, be fixed on the workbench, the mould 6 that opening makes progress, the mould top is fixed in inversion, lower piston bar 11 end pressure heads 8 face the hydraulic cylinder 12 of mould upper shed, it is characterized in that: described workbench 4 places on the stage clip 3 that is fixed on base 1, be fixed with below the workbench and can make workbench vertically to the ticker 2 that vibrates, described bottom is fixed with and is with the vacuum seal lid 9 that can cover the mould upper shed when pressure head stretches into mould on the hydraulic cylinder piston rod 11 of pressure head 8 with being slidingly matched, vacuum seal covers and is provided with an end and can communicates with dies cavity, the vacuum-pumping tube 10 that the other end can link with vavuum pump, be provided with the movable floor 5 that can cover bottom opening in the described dies cavity, being provided with between described hydraulic cylinder and mould can be with the two pressure conducting parts 7 that is connected as a single entity in the vertical direction relative fixed.

The operation principle of this device is, during work, upper hydraulic cylinder pressure head 8 moves downward, and pressurization makes its moulding to the material in the mould, in this simultaneously, is fixed with the vibration that the workbench 4 of ticker produces above-below directions, impels the material in the mould to be pressed more closely knitly.This moment is because the pressure conducting parts that is provided with between hydraulic cylinder and the mould is linked as an integral body with the two in the vertical direction relative fixed, pressure head is cancelled each other in this whole interior to the tension that produces in material applied pressure in the mould and the pressure conducting parts, and not acting on workbench, workbench need only bear the gravity of upper unit.Simultaneously, when pressure head moved downward to mould, the vacuum seal lid mould upper shed soon that is enclosed within on the expansion link covered, and vavuum pump can be by being located at the air in the vacuum-pumping tube extraction mould that covers, and it is molded that material is subjected under vacuum state.After the moulding, make the goods demoulding for the movable floor reinforcing of mold bottom.

The utility model can adopt hydraulic pressure to the material extrusion forming in the mould under vibration and the state that vacuumizes, improved the density of carbon graphite goods greatly, bulk density as the graphite electrode green billet that processes with this make-up machine can reach 1.72-1.75, the bulk density of its graphitization blank can reach 1.62-1.68, reduce 15-25% with the unit consumption of its steel-making than the electrode of existing extrusion modling machined, and because it is provided with the pressure conducting parts, also can alleviate the load of bottom vibrating mechanism, so simplified shaping machine structure and dwindled its volume.

The embodiment explanation

The structure of this routine pressure conducting parts 7 is: cover one case on hydraulic cylinder 12, the flange of case upper port is placed on the flange of hydraulic cylinder sidewall, the downward length of case should be enough to make mould 6 upper port to stretch into the case lower port, mould side wall is provided with the hooked scarf to outer lug, the case lower port is provided with the barb that turns inwards, upwards hook the hooked scarf on the mould side wall from the bottom, also be provided with on the case vertically to chute hole, be housed in the vacuum-pumping tube 10 that the vacuum seal in the shell covers and pass from this hole.

When pressure head is given the downward pressure of material one in the mould, mould is about to this pressure and is transmitted on the barb of case under shed portion by the hooked scarf on its sidewall, give hydraulic cylinder one downward power, thereby make this pressure not act on workbench 4, this pressure conduction device not only can be vertical with mould to being connected as a single entity with hydraulic cylinder when pressure head is worked, and also be convenient to the two separation after processing product, so that goods are taken off in mould.When hydraulic cylinder piston rod moves up and down, the vacuum-pumping tube that vacuum seal covers can move up and down by the vertical chute hole on case, and when pressure head pressurizeed downwards, vacuum seal covered in the mould upper shed, tight for sealing, vacuum seal covers the position that contacts with mould and is provided with elaxtic seal.

Present embodiment makes the hydraulic cylinder reversal of the natural order of things that its afterbody is fixed on the crossbeam, after extrusion forming finishes like this, pressure conducting parts case can be rotated an angle, barb on it and the hooked scarf on the mould side wall be staggered disengage, case be mentioned to carry out stripping process.

The ticker 2 of present embodiment is to be provided with in pairs, is driven by speed change gear 14 by motor 13, according to rightabout, rotate with same rotational speed, and its center of gravity phase phasic difference 180 degree.

Also vibrating motor can be directly fixed in pairs the bottom of workbench 4, make that wherein ticker direction of rotation is opposite, rotary speed is identical and center of gravity phase phasic difference 180 degree.

Since its in the opposite direction, identical speed rotation, and center of gravity phase phasic difference 180 degree, so but offset by the level of do vertically to vibration to component.
