Abstract
The invention discloses a process for manufacturing rounding steel shots for clearing and de-rusting by using special steel wires for tyres. The process comprises the following steps of: (1) heating the special steel wires for the tyres or waste tyre bead wires to the temperature of between 450 and 600 DEG C in a natural high-temperature furnace, and performing quenching treatment to remove glue and other impurities on the steel wires; (2) cutting the quenched crisp steel wires into small cylindrical sections through a wire cutter, wherein the length of the steel wire sections is 1 to 1.2 times diameter; (3) putting the cut steel wires into a rounding machine, and performing repeated cyclic throwing so that the steel pots become round; (4) screening the thrown and rounded steel shots; and (5) performing roundness sorting. The process has the advantages that: 1, the production process is simplified, the production efficiency is improved, and the manufacturing cost is reduced; 2, the manufactured steel shots have low granularity difference and have abrasion rather than breakage during use, and the service life of the steel shots are over 6 times that of cast steel shots; and 3, the process is suitable for large-batch production and suitable for popularization in economically underdeveloped areas.
Description
Technical field:
The invention belongs to the metal abrasives field, particularly a kind of the making with the tire special steel wire cleared up, eliminated rust with the manufacture craft of throwing the round steel ball.
Background technology:
The production of the cast steel ball of China's production at present and use need be heated to starting material such as steel scrap and make it to become molten steel more than 1600 ℃ with middle frequency furnace, and then specific equipment is with the molten steel granulation that atomizes, this particulate metallographic structure is: therefore as-cast martensitic is referred to as: cast steel ball.Cast steel ball exist defectives such as pore, crack are loose, in use the percentage of damage height causes huge waste to the user.And the atomizing granulation process of its production technique has uncontrollability, and granularity is different, and the test marketing specification only accounts for about 60% of all prods.
Summary of the invention:
Purpose of the present invention provides a kind of and makes cleaning, the rust cleaning production technique of throwing the round steel ball with the tire special steel wire with regard to being the above-mentioned the deficiencies in the prior art of customer service, the shot long service life of utilizing this explained hereafter to go out, and production cost is low.
Technical scheme of the present invention is: a kind of with tire special steel wire making cleaning, the rust cleaning manufacture craft of throwing the round steel ball, it is characterized in that: carry out: 1. tire special steel wire or junked tire tire mouth silk are heated to 450-600 ℃ of glue and other impurity of doing on the quench treatment removal steel wire in the natural high-temperature stove according to the following step; 2. the above-mentioned steel wire that becomes fragile through quenching is cut off processing by filament cutter and make it cylindrical segment, length is 1-1.2 times of diameter; 3. the steel wire after will cutting off is put into and is thrown circular knitting machine, with the impelling that circulates repeatedly of the speed of 80 meter per seconds, makes it to become circle, and the impelling time is 30-60 minute; 4. the shot after the impelling rounding is sieved; 5. the shot after will sieving carries out the circularity sorting, will not justify ball, inclined-plane ball, the full scale clearance of burr ball with choosing circle device.
Above-mentioned tire special steel wire or junked tire tire mouth wire chemical composition are (weight %): C:0.6-0.70%, Si:0.1-0.35Mn:0.3-0.5%, P: S≤0.03% :≤0.03%, Cr≤0.06%, Ni :≤0.06%, and metallographic structure: perlite.
Above-mentioned filament cutter is in the cutting-off process to steel wire, and the cutting angle of cutting knife is between 75 °-80 °.
Above-mentioned screening is three layers of group sieve; The first layer screen cloth: segment diameter ± 0.2mm; Second layer screen cloth: segment diameter ± 0mm; The 3rd layer of screen cloth: segment diameter-0.2mm.
The present invention has following advantage and positively effect:
1, simplified production technique and improved production efficiency, reduced cost of manufacture.It is raw material that this production technique is selected tire special steel wire or junked tire tire mouth silk for use, and tire mouth silk has been carried out quench hot, has improved the fragility of raw material, has reduced cutting resistance, makes it to be easy to machining, can effectively raise the efficiency more than 4 times.The cutting angle of cutting knife in the work-ing life of having improved cutter, can significantly reduce bending section, bevel phase between 75 °-80 ° in working angles simultaneously.
2, because the steel wire of this production technique after will cutting off put into the throwing circular knitting machine with the impelling that circulates repeatedly of the speed of 80 meter per seconds, make it to become circle, the impelling time is 30-60 minute, and through three layers of screening, therefore the shot particle size differences of producing is little, defectives such as pore, crack can not occur, in use having only wearing and tearing not have disrepair phenomenon, work-ing life is more than 6 times of cast steel ball.
3, be applicable to production in enormous quantities, be applicable to that the economically less developed region promotes.
Embodiment:
A kind made from the tire special steel wire cleared up, eliminated rust with the manufacture craft of throwing the round steel ball, it is characterized in that: carry out according to the following step:
1, selected raw material is tire special steel wire or junked tire tire mouth silk, its Chemical Composition is (weight %): C:0.6-0.70%, Si:0.1-0.35Mn:0.3-0.5%, P: S≤0.03% :≤0.03%, Cr≤0.06%, Ni :≤0.06%, and metallographic structure: perlite.
2, tire mouth steel wire is heated to 600 ℃ in the natural high-temperature stove, does quench treatment, remove photoresist, impurity to be to improve fragility, is easy to machining.
3, filament cutter cuts off processing to the quenching steel wire, cylindrical segment, and length is 1-1.2 times of diameter.So reduced cutting resistance because tire mouth steel wire has increased fragility, can effectively raise the efficiency more than 4 times.Simultaneously, bevel phase in working angles and burr significantly reduce.Change the cutting angle of cutting knife into 75 °-85 ° by original 50 °-60 °, thereby improve the work-ing life of stage property, can significantly reduce bending section, bevel phase.
4, throw the making of round steel ball: steel wire is cut off being placed on throw in the circular knitting machine, with the impelling that circulates repeatedly of the speed of 80 meter per seconds, make it to become circle, the impelling time is 30-60 minute.
5, quality test: observing throwing circle ball under 20 times magnifying glass does not have obvious corner angle, burr.
6, method for sieving: three layers of group sieve;
The first layer screen cloth: segment diameter ± 0.2mm.
Second layer screen cloth: segment diameter ± 0mm.
The 3rd layer of screen cloth: segment diameter-0.2mm.
7, circularity sorting: will not justify ball, inclined-plane ball, the full scale clearance of burr ball with homemade spiral choosing circle device.
8, warehouse-in.
The present invention throws the experiment contrast (seeing the following form) of round steel ball and cast steel ball wear rate in same shot-blasting machine
Fragmentation experiment (experiment specification ∮ 1.0 hardness: 45HRC) of two kinds of shots in the same shot-blasting machine of our factory
Conclusion:
Throw round steelBall has only abrasion not have fragmentation, work-ing life to be
Cast steel ballMore than 6 times.
