Description
Technical field
The utility model belongs to graphite carbon rod technical field of processing equipment, specifically a kind of new die pattern carbon-point extruder.
Background technology
Manufacture carbon-point with graphite and be widely used in medical treatment, cutting/fields such as welding.In carbon-point process, after need to be first mixing in proportion with materials such as carbon dust, graphite powder and pitches, be first pressed into carbon cake, then be extruded into the carbon-point of the strip of required cross sectional shape, then to carbon-point reprocessing, finally electroplate copper mold and obtain finished product.Due to the restriction of processing conditions, carbon dust, graphite powder are mix at normal temperatures, suppress and extrude with materials such as pitches, and mixture cannot reach as resin material viscosity.So, in the time using hydraulic pressure extruder, there will be when extruding carbon-point, can occur, under some formula, cannot extrude smoothly carbon-point.
Summary of the invention
In order to solve the problems referred to above that occur in prior art, through research of technique, the utility model proposes following technical scheme:
A carbon-point extruder for new die pattern, comprises body, hydraulic press and mould; In described body, have columniform cavity; Described hydraulic press is contained in the head end of body, and the piston rod of hydraulic press gos deep into the head end of cavity, and closely connected with the inwall of cavity; Described mould is contained in the tail end of body, and the feed end of the die cavity of mould is communicated with cavity; The axial level of described cavity is in ground; Described mould is spliced to form successively by polylith template; For arbitrary template, template center position has through hole; The axis of the through hole of all templates is identical, and the through hole of all templates is similar figures; For wantonly two adjacent forms, hole size difference, and be greater than the through hole towards mould discharging end towards the through hole of die feeding end; The template of splicing successively, their through hole forms the die cavity of mould.
(the technical program changes the pattern of existing mold, adopts differential thought, and die cavity is divided into multistage.Because multistage die cavity can constitute the die cavity at wall angle of inclination, multiple chamber, like this, can under the prerequisite of a mold, realize extruding of multiple formulations carbon-point batch mixing, meet the requirement of extruding of different densities, viscosity batch mixing.)
The external shape of all templates is identical, and same position in all templates is provided with pin-and-hole, and the respective pin hole of each template connects locking by same pin.(this improvement is the standardization in order to realize mould, is convenient to assembling.)
Also involving vibrations machine; On the piston rod of described hydraulic press, be connected with baffle plate, baffle plate perpendicular to piston rod axially, and the length of piston rod before baffle plate is not less than the length of cavity; The shake table of bobbing machine is connected on described baffle plate by connecting rod, and connecting rod is vertical with baffle plate; On the other ground of body, be provided with guide rail, the body of bobbing machine is connected on guide rail by support; And bobbing machine is at the other rear of hydraulic press; Support is connected by one-way intermittent motion mechanism with guide rail.
(problem that this improvement solves is that the outer wall of the carbon-point of extruding there will be bed separation phenomenon, in the later stage, must adopt the method for polishing.Like this, just cannot accomplish to control by mould the object of carbon-point section shape and size, and post facility, personnel drop into very greatly, yield rate is very low.On extruder is extruded, add bobbing machine, on the basis of extruding action, have again vibration action.The frequency of vibration action is higher, and have certain amplitude, can auxiliary hydraulic pressure machine several times moment high speed extrusion, the viscous force between carbon-point outer wall and mould is just very little on the impact of carbon-point material like this, be not enough to resist the viscous force between carbon-point batch mixing, eliminated bed separation phenomenon., in experiment, find, adopt after vibration measure, the plasticating capacity of hydraulic press also obtains very large reinforcement meanwhile, and former part formula batch mixing cannot be extruded situation, on this extruder, can extrude smoothly.)
Between described bobbing machine body and support, be lined with vibration isolator (avoid Long-term Vibration to cause be connected with support loosening); Between body and ground, be lined with vibration isolator; Between hydraulic press and ground, be lined with vibration isolator (avoiding the vibration from ground).
The excited frequency of described bobbing machine is that 8Hz/s～14Hz/s, amplitude are 1.3mm～2.8mm.(because the acting overwhelming majority that extrudes of extruder comes from hydraulic press, and the effect of bobbing machine is to have the power-assisted of moment to make the moulding in the time not occurring that stratiform comes off of carbon-point outer wall to piston rod, so the concrete numerical value of exciting force is without particular requirement.And for shaking frequently and amplitude, be will consider apparatus body to be mainly rigid material, material has certain wave absorbtion, crosses good frequency and too small amplitude (amplitude is corresponding with extruded velocity), all can cause vibrating effect not good, even there is no effect).
Described piston rod have cannelure with baffle plate junction, baffle plate center has the through hole corresponding with cannelure, the inwall of through hole and the inwall of cannelure are closely connected, and baffle plate and piston rod are for being welded to connect.(in the time of Project Realization, baffle plate is welded by two identical identical steel plate splicings.)
Described connecting rod has four, and they are in a center of symmetry around piston rod.
One-way intermittent motion mechanism between support and guide rail comprise be connected to frame bottom steamboat, be connected to the ratchet on little wheel shaft, and along guide rail lay toothed chain; Described steamboat is walked on guide rail, ratchet and toothed chain interlock.(bobbing machine advances with piston rod, and by the interlocking between ratchet and toothed chain, bobbing machine is relative fixing with the position on ground, plays effect of vibration.)
