Description
Technical field
The invention belongs to the manufacture field of brush, particularly relate to a kind of forming graphite carbon brush machine filler device.
Background technology
Graphite carbon brush is also electrographite brush, as a kind of slide contact member, is widely used in many electric equipments.The material of graphite carbon brush mainly contains graphite, leaching fat graphite, metal (cupric, silver) graphite.Carbon brush is the device of transferring energy or signal between the standing part of motor or generator or other rotating machineries and rotating part, it be generally pure carbon add coagulating agent compacting form, it is square as profile, be stuck on metallic support, and be communicated with by wire, there is spring handle the inside, and it is pressed in rotating shaft, when electric machine rotation, electric energy is flowed to coil by commutator.Forming graphite carbon brush machine is then be specifically designed to the equipment producing graphite carbon brush.Existing forming graphite carbon brush machine, mainly comprises control system, feed mechanism, shaping mechanism and discharging mechanism.Powdered graphite and coagulating agent mix, and send in die cavity from feed mechanism, and insert wire, by shaping mechanism, raw material is compressing, meanwhile, in the extrusion process of raw material, wire is also fixed in the feed, and define graphite carbon brush, whole process controls by controller.If notification number is the patent of CN201797222U, disclose a kind of Full-automatic carbon brush forming machine, comprise a control system, workbench, and by the feed system of described control system control, the compact system of compacting carbon brush; Described workbench is provided with a table top upward, and described table top is provided with charging aperture, is provided with carbon brush mold below described charging aperture; Described feed system comprises the feed box holding material, is provided with discharging opening, and is positioned on described table top below described feed box; Described feed system also comprises the feed box driving mechanism of a driving feed box translation.Feed box translation on table top is driven by the feed box driving mechanism in described feed system, when feed box moves to the discharging opening position overlapping with described charging aperture, raw material in feed box falls in the die cavity of the described carbon brush mold below described charging aperture, and inserts wire in mould.By suppressing the described compact system of carbon brush, the material in described carbon brush mold is exerted pressure, thus form carbon brush.
But owing to inserting extrusion modling together with raw material in wire, excessive extruding force easily causes wire fracture, so the extruding force of shaping mechanism when compressing is unsuitable excessive, finally cause shaping after the density of graphite carbon brush lower, thus scuff resistance is low, easily weares and teares.
In order to solve the problem, take new technique: the raw material first powdered graphite and coagulating agent mixed by the press-forming machine of high pressure is pressed into that density is high, anti abrasive blank at elevated pressures, after after blank sintering, intensity and abrasivity promote further, be delivered in rig by pay-off and carry out boring process, wire is put in the hole of having bored, and in hole, add powdered graphite and coagulating agent, the high graphite carbon brush of scuff resistance can be obtained after carrying out grinding process after compression.Because said process is all completed by workman's manual operations, inefficiency.
So be badly in need of a kind of forming graphite carbon brush machine of mechanization.
Summary of the invention
Object of the present invention is providing a kind of forming graphite carbon brush machine filler device, to improve the operating efficiency making the high graphite carbon brush of scuff resistance.
In order to achieve the above object, the invention provides a kind of forming graphite carbon brush machine filler device, comprise depression bar, barrel, hydraulic pressure tong, lifter and controller, described lifter, hydraulic pressure tong are all electrically connected with controller, and described barrel is tapered, and barrel is positioned at hydraulic clip side on hand, described depression bar is provided with wire guide along depression bar axis direction, described wire guide can supply wire and pressure shaft to relative motion, and described depression bar is fixed on lifter, and depression bar can block the discharging opening of barrel.
Principle of the present invention is: hole-drilled blankholder fastens by hydraulic pressure tong, the hole of blank put into by wire guide wire being passed depression bar, and controller controls lifter and moves up, and now depression bar moves, the discharging opening of barrel is opened, and raw material enters in the hole of blank from barrel.Controller continues to control lifter moving down back and forth, and constantly by the discharging opening conducting of barrel and blocking, meanwhile, the raw material in hole compresses by depression bar, completes filler operation.
Beneficial effect of the present invention is: barrel is tapered, then the raw material in barrel can enter into the hole that base substrate bores under gravity, without the need to external force.Wire guide can supply wire and pressure shaft to relative motion, and when depression bar moves up and down under the effect of lifter, wire can keep motionless, and the raw material in hole compresses by depression bar, can increase the intensity after raw material compacting in hole.Depression bar moves up and down, and except conducting is with except the discharging opening of blocking barrel, also raw material is had to the effect of compression, meanwhile, upper and lower moving back and forth can touch raw material, makes blank produce shake, thus adds the compactness of raw material in blank.
Further, described tong is provided with vibrator.Vibrator produces vibration, makes the raw material in blank hole more even.
Further, the diameter of described wire guide is greater than the external diameter 1-2mm of wire, when the difference of the diameter of wire guide and the external diameter of wire is less than 1mm, when depression bar moves up and down, easy drive wire moves, when the difference of the diameter of wire guide and the external diameter of wire is greater than 2mm, then easily make the aperture of wire guide excessive and cause wire at wire guide bias internal.
Further, described controller is PLC, and PLC is simple to operate, and editability is strong.
Further, described depression bar is provided with spheroid near one end of blank, and the inwall of described spheroid and barrel discharging opening is tangent.The depression bar of this design is to the better tightness of barrel discharging opening.
