Abstract
The invention relates to a method for producing the parts of a duplicator and a printer, in particular to a method for producing a developing magnetic roll. The method mainly comprises the following steps: granulating, injection-molding, steel shaft mounting, demagnetizing and magnetizing, and the method further comprises the step of profile processing. The invention has the following beneficial effects that: the magnet is subjected to one-piece injection-molding instead of adhesion, thereby preventing the magnet and core shaft from getting loose to cause the change in the intensity of the magnetic field; the magnetic obliquity and the intensity of the magnetic field are guaranteed by the mold, thereby ensuring the uniformity in product performance; and the molded magnet is further subjected to profile processing, thereby eliminating the defect that the two end surfaces of the magnetic roll are not smooth and preventing the operation from being retarded when in use.

Background technology
At present; The working method of each employed developing magnetic roll of consumptive material manufacturer be by the logical mandrel (Φ 4-Φ 6) of a metal go up bonding 4 independently magnetic stripe to obtain magnetic characteristic; Its magnetic pole angle is by assembling jig control, is characterized in that magnetic table intensity controls easily, makes simplicity of design.But, there is following shortcoming because magnetic stripe is on metal shaft, to form through bonding agent is bonding: 1) magnetic pole angle control difficulty, homogeneity of product is bad; 2) be easy to generate looseningly between magnetic stripe and the axle, cause table magnetic variationization and problem such as deform; 3) because magnetic stripe is not reprocessed after bonding, and its magnetic roller both ends of the surface are uneven, the running retardance very easily takes place.
Summary of the invention
In view of prior art is not enough, the invention provides a kind of working method of developing magnetic roll, it is characterized in that: mainly comprise granulation, injection moulding and, also comprise sharp processing by dress steel axle, the process of demagnetizing, magnetize; Concrete production stage is:
Step 1: granulation
1. weighing mixes: with ferrite, nylon, silicone couplet, isopropyl alcohol be 93% by weight percentage, nylon 5.5%, silicone couplet 1.25%, isopropyl alcohol 0.25% weighing; Ferrite and mixed silicone couplet, isopropyl alcohol are put into mixing tank; Get into mixed once; After the mixed once, drop into nylon, carry out secondary and mix;
2. mixing: that 1 section temperature of mixing roll is set in 185 ℃; 275～290 ℃ of 275～290 ℃, 7 sections temperature of 275～290 ℃, 6 sections temperature of 275～290 ℃, 5 sections temperature of 275～290 ℃, 4 sections temperature of 275～290 ℃, 3 sections temperature of 2 sections temperature; After the mixing roll temperature reaches setting value; Mixed material powder through the weight feed machine, is imported mixing roll;
3. cooling: the mixing roll extrudate is placed on cooling and transmission on the cooling conveyer belt; 4. pelletizing: open pelleter extrudate is cut into required material grain;
Step 2: injection moulding is also installed the steel axle
The material grain that 1. will make sucks in the baking batch can, sets bake out temperature oven dry material grain;
2. injection machine is prepared: injection molding magnetic roller die tool is hung in injection machine, configure method parameters such as metering, pressure, speed, time, temperature;
3. the mandrel band is a flat end embeds in the locating piece in the mould;
4. start injection machine, open the blanking of feed bin dividing plate, residual material in the injection machine material chamber is ejected, head is docked with magnetic roller die tool charging aperture coincide, can not leave the gap.Function beginning is transferred to semi-automatic, injection moulding begins;
Step 3: demagnetization
1. adjust the demagnetization power supply: divide three sections voltages that will demagnetize to transfer to 1500v;
2. demagnetization: magnetic roller integral body is all sent in the degaussion coil, accomplished demagnetization;
Step 4: sharp processing step
With external diameter lathe or grinding machine processing external diameter, processing two ends end face on the lathe of two ends;
Step 5: step magnetizes
1. anchor clamps wiring: select and the corresponding magnetizing clamp of magnetic roller to be charged, connect power lead;
2. make marks: make marks on the left magnetic roller He on the anchor clamps respectively;
3. adjust voltage: start the power supply that magnetizes, adjustment voltage range, segmentation adjustment voltage to method required value;
4. magnetize: the mark on magnetize on the magnetic roller mark and the magnetizing clamp is aligned, magnetic roller integral body is all sent in the magnetizing clamp, press pre exciting switch, completion is magnetized.
The invention has the beneficial effects as follows,, avoided producing between magnet and the mandrel loosening and the variation magnetic field intensity that causes because that magnet is that integral molded plastic does not carry out is bonding; And magnetic obliquity and magnetic field intensity guarantee by mould, have guaranteed uniformity in product performance; Because the magnet after the injection moulding will pass through sharp processing, thereby has eliminated the rough phenomenon of magnetic roller both ends of the surface, the situation of the retardance of in use can not turning round.
