Description
Technical field
The utility model belongs to graphite carbon rod technical field of processing equipment, and specifically a kind of carbon cake is pressed into machine.
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 and suppress with materials such as pitches, and carbon dust and graphite powder are powdery, pitch addition can not be too high, and (pitch complicated component, after addition is too high, can cause in product impurity residual excessive, affect the quality of product), mixture is coccoid (size is similar to Chinese patent pills core), in the time being pressed into carbon cake, is difficult to accomplish gapless in carbon cake.In order to reduce gap, general way is to strengthen hydraulic press pressure, and large its price of hydraulic press of output pressure is considerable, meanwhile, because differences such as the formula of batch mixing, density, viscid degree, addresses this problem extremely unwise by the single thinking of large output hydraulic pressure machine.
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 kind of carbon cake is pressed into machine, comprises frame, hydraulic press and mould; Mould comprises punch and die; Frame is provided with job platform, and job platform upper surface is provided with die locating slot, and described die is placed in die locating slot; A guide rod perpendicular to job platform upper surface is housed respectively on four jiaos of frame, the body of hydraulic press is contained in the top of guide rod, it is characterized in that being connected with punch and settle platform between hydraulic press and job platform, described punch is contained in the lower surface of punch arrangement platform, punch settles four jiaos of platform to have a guide hole, and each guide hole correspondence is enclosed within on a guide rod; The piston rod of hydraulic press settles platform to be connected with punch; Also involving vibrations machine; Bobbing machine is positioned at the top of hydraulic press; The shake table of bobbing machine connects punch by connecting rod and settles platform; Also comprise punch arrangement platform position sensor; Punch settles the signal output part of platform position sensor to connect the switching signal input of bobbing machine.
(be originally pressed into machine, on the basis of pressing action, have again vibration action.The frequency of vibration action is higher, and there are certain amplitude and exciting force, can auxiliary hydraulic pressure machine moment presses down at a high speed energetically several times, this instantaneous pressure can make the gap in carbon cake less still less, and because the own pressure of hydraulic press that plays decisive factor can be not very big, so it is excessive that the packing of carbon cake can't increase, and subsequent technique is increased to difficulty.
The reason that arranges of travel switch is, in trial-manufacturing process, finds, if hydraulic press and bobbing machine are worked simultaneously, the material that punch hits in die can cause material to spill in a large number die.And after carbon cake has been pressed into a certain degree, then vibrate, material itself has become piece, and coordinates by punch the problem of just having avoided material to spill with die.)
In described guide hole, copper sheathing is housed.(because the shake table of punch arrangement platform and bobbing machine is rigidly connected, guide rod and guide hole are subject to vibration effect and mutually knock, and affect equipment life.And the hardness of copper material itself is not too high, can absorption portion vibrational energy, reduced the energy that knocks between guide rod and guide hole, and copper sheathing can be changed, and cost is not high.)
It is travel switch that described punch is settled platform position sensor, and the trip switch connects job platform by montant, and is positioned on punch arrangement platform walking path.(travel switch is mechanical type, and it is subject to the impact of environment dust pollution less, and meanwhile, it connects job platform by montant, has avoided settling platform to be directly connected with the punch that has vibration, further improves reliability.)
Also involving vibrations machine position-limit mechanism, this mechanism comprises at least one pair of pole, paired pole becomes axial symmetry about hydraulic machine piston bar; The vertical dress of pole on the ground; On described bobbing machine, baffle plate is housed, the edge of baffle plate is equipped with ratchet, and the toothed chain corresponding with ratchet is housed on pole, ratchet and toothed chain interlock.(this improved principle is to settle platform to impose downward power, the bobbing machine upwards resilience of simultaneously with ratchet catching toothed chain avoid exciting force bring by own wt to punch when bobbing machine.)
Between pole and ground, be provided with vibration isolator; Between frame and ground, be provided with vibration isolator.
The excited frequency of described bobbing machine is that 24Hz/s～36Hz/s, amplitude are that 1.8mm～2.4mm, exciting force are 0.8KN～2.2KN.(consider compaction rate unsuitable excessive of carbon cake, and gap in carbon cake should be less, less, and the assembly of this equipment majority is stiff member, reaches above-mentioned scope so adjust the parameter of bobbing machine, can adapt to the material requirement of common component.)
