Abstract
The invention pertains to the technical field of metal heat treatment and relates to a surface treatment technology of a cast iron grooved drum. The surface treatment technology comprises the processes of quenching and tempering, oil cooling, annealing, nitriding, nickel and phosphor plating, vacuum quenching, and has the advantages that the processed metal grooved drum has the surface hardness more than or equal to 900HV and the surface roughness Ra less than or equal to 2.5 microns, has even surface and uniform color, spares defects such as obvious bubbles and shedding in visible parts, andis superior to similar products abroad in wear resistance, roughness and conductivity. The surface treatment technology enables the cast iron grooved drum to be applied to an automatic cheese windingmachine, which can reduce production cost, remove the bottleneck of restriction by foreign competitors, accelerate the localization of the automatic cheese winding machine and drive the technologicalprogress in the textile industry in China.
Description
Technical field
The present invention relates to the metal heat treatmet technical field, refer in particular to a kind of process of surface treatment of cast iron grooved drum.
Background technology
Groove drum is the crucial accessory that is used for doff on the weaving loom of textile industry, groove drum has the plastics groove drum by the material branch, steel plate groove drum and metal drum, the principle of work of metal drum is carried out doff according to friction transmission coiling principle, in this mechanism, take the metal drum of special processing, directly drive by dc servomotor, the bobbin that is installed in the ingot hand-to-arm grip is pressed on the groove drum, rely on the axis revolution of the rubbing effect of groove drum around self, the coiling yarn, the groove on groove drum surface as yarn carrier make yarn equably network be rolled onto the bobbin surface, the shape of groove has determined the guide laws of motion, dissimilar acceleration curves has guaranteed to reach needed groove drum starting velocity, and the transmitting ratio between computer control groove drum and the tube yarn is during Yarn break, the hand-to-arm grip of tube ingot is lifted automatically, make bobbin break away from the groove drum surface as early as possible, in order to avoid yarn excessively frays optimized flute profile design and surface treatment, for the high speed doff provides good basis, also guaranteed the appearance forming quality of tube yarn simultaneously.
Along with the development of society and the demand of textile industry, semi-automatic bobbin winder has not caught up with produces fast development, situation on the verge of being replaced, and fully-automatic spooling machine is monopolized by external producer, only to the domestic market import of complete machines, crucial spare and accessory parts are then forbidden to domestic import, carry is not metal drum, according to the market forecast of country weaving authoritative department " the weaving and knitting preparation production development Ninth Five-Year Plan and in 2010 ", the whole nation was 150,000 from the aggregate demand of network groove drum in 2008, after 3 years, the domestic needs amount will reach 300,000, country's textile industry is badly in need of the groove drum processing units and is realized breaking through, and to solve the bottleneck that influences the textile industry development, reduces production costs.
At home, be applied to metal drum on the automatic winder all from external import, price height and quality are low, the metal drum that our company develops voluntarily is a copper network molybdenum alloy cast iron material, because material, surface irregularity low cylinder iron with the hardness that milling machine mills the metal drum of making, can't directly apply to production, need carry out special thermal treatment and can make its hardness, wear resistance, roughness, conductivity reach service requirements, and can join for the thermal treatment process no data of cast iron grooved drum both at home and abroad
Summary of the invention
The process of surface treatment that the purpose of this invention is to provide a kind of wear resistance, roughness, cast iron grooved drum that conductivity is good
The object of the present invention is achieved like this: the process of surface treatment of cast iron grooved drum, finish by following step:
(1) modified: as the cast iron grooved drum that processes to be placed in 650-700 ℃ the hardening and tempering furnace modified;
(2) oil cooling: the oil drum that the cast iron grooved drum with step (1) after modified is put into normal temperature carries out oil cooling to normal temperature;
(3) anneal: the annealing furnace annealing of the cast iron grooved drum behind step (2) oil cooling being put into 380-400 ℃;
(4) nitrogenize: the cast iron grooved drum after step (3) annealing is carried out nitriding;
(5) nickel plating and phosphorus: the cast iron grooved drum after step (4) the nitriding processing is carried out while nickel plating and phosphorus;
(6) vacuum hardening: the temperature range of the cast iron grooved drum after step (5) nickel plating and the phosphorus processing being put into inherent 400-420 ℃ of vacuum quencher is carried out vacuum hardening.
The surface hardness of the cast iron grooved drum behind above-mentioned step (4) nitriding treatment is 750-850HV.
Thickness of coating 〉=0.03mm after (5) nickel plating of above-mentioned step and phosphorus are handled.
Surface hardness 〉=the 900HV of the cast iron grooved drum after above-mentioned step (6) vacuum hardening is handled.
The outstanding compared to existing technology advantage of the present invention is:
1, the surface hardness height of the metal drum of handling with the present invention: 〉=900HV, work-ing life 8-10, and the surface hardness of traditional groove drum is 300HV, 1-2 week in work-ing life;
2, the surfaceness of the metal drum of handling with the present invention: Ra≤2.5 μ m, surfacing, gloss is even, and visible position does not have obvious bubble and bumps and defective such as take off, and its wear resistance, roughness, conductivity obviously are better than external like product.
3, the present invention makes cast iron grooved drum be applied to become possibility on the automatic winder, has reduced production cost and has been subjected to the external bottleneck that restricts, and can quicken the production domesticization paces of automatic winder, promotes the scientific-technical progress of China's textile industry.
