Description
Technical field
The present invention relates to a kind of cutter, especially a kind of granules cut moving knife that is used for PET industry also relates to its manufacture method simultaneously, belongs to the cutting-tool engineering field.
Background technology
The cutting tool of granules cut moving knife that PET industry is used and so on is worked under water, changes difficulty, requires life cycle long, and the edge of a knife is sharp, wear-resistant, corrosion-resistant.At present, the edge of a knife material of this type of large-scale cutter mainly adopts cobalt-base alloys (being commonly called as Si Taile alloy STELLITE12#) bead-welding technology to make, promptly elder generation's circumference on the matrix steel is opened one group of equidistant groove along bus, follow built-up welding cobalt-base alloys in groove, mill the matrix material between the adjacent built-up welding cobalt-base alloys again, expose cobalt-base alloys, at last at cobalt-base alloys grinding cutting edge.Its shortcoming is the manufacturing process complexity, and efficient is low, and because of containing the rare metal cobalt in the material, costs an arm and a leg.
Summary of the invention
The objective of the invention is to propose a kind of the maintenance under original cutting performance prerequisite, the granules cut moving knife of convenient manufacturing process, cost economy provides its manufacture method simultaneously, thereby replaces the Si Taile alloy, satisfies the needs that PET industry is cut under water.
In order to reach above purpose, the applicant is by experiment repeatedly, the technical scheme of granules cut moving knife has been proposed, this cutter comprises columniform main body, and the outer round surface of described main body axially (roughly direction) has equidistant caulking groove, difference mosaic blade tool section in the described caulking groove, filling fusion material between described edge blade and the caulking groove is connected by vacuum brazing, described edge blade is grouped into by the one-tenth of following percent by volume: matrix martensitic stain less steel 96-98%, and TiC2-4%, wherein TiC is with 10-10
2The nm disperse is distributed in the matrix stainless steel.
The matrix stainless steel can be various martensitic stain less steels, and especially with 2Cr13 performance the best, and 2Cr13 accounts for 97vol%, cutting performance was best when TiC accounted for 3vol%.
Usually the stainless composition of matrix is---C:0.1～0.34%; Cr:12～14%; Si≤0.60%; Ni≤0.60%; Mn :≤0.60%; S≤0.03%, surplus are Fe.
May further comprise the steps with the manufacture method of fixing a cutting tool:
A, make that main body---machining goes out the cutter body that outer round surface axially has equidistant spiral caulking groove;
B, manufacturing cutting edge
B1), melting---after the martensitic stain less steel melting, add Ti, C, Fe ultra-fine grinding in the required ratio of finished product, particle diameter is less than 0.1 millimeter, and temperature is controlled at 1800 ℃---, forms 10-10 by 2000 ℃
2The disperse distribution TiC of nm;
B2), processing---behind the cutting edge material ingot casting after the melting, blanking, be processed into the tool section that matches with the caulking groove width;
C, inlay melting welding---will fill the melting welding filler in the main body caulking groove, again with edge blade respectively setting-in be fixed in each caulking groove fixingly, heat to the melting welding temperature, make that melting welding is connected between edge blade and the caulking groove.
More than the disperse of TiC uniform particles is formed material have desirable hard phase, thereby reach the purpose of strengthening material.Experiment showed, that this material is corrosion-resistant and mechanical performance is all very good, can substitute the Si Taile alloy fully and cost is more much lower than Si Taile alloy.Be appreciated that, the present invention is owing to create the cutter material of high comprehensive performance and cost economy, and change traditional bead-welding technology on this basis, the method that the final vacuum soldering is inlayed in employing produces satisfactory granules cut moving knife, therefore can replace the Si Taile alloy, satisfy the needs that PET industry is cut under water.

The specific embodiment
Embodiment one
The edge blade material of granules cut moving knife is made according to the following steps in the present embodiment
1) material---with Ti, C, Fe ultra-fine grinding, particle diameter is less than 0.1 millimeter, to prepare interpolation;
2), the melting matrix material---selecting stainless steel 2Cr13 for use is matrix material, carries out melting in vacuum or medium-frequency induction furnace;
3), the interpolation comminution of material---in the matrix material of fusing, press the proportion requirement of matrix material 97vol%, synthetic back Ti3vol%, add pulverizing back Ti, C, Fe powder, temperature is controlled at more than 1800 ℃ and (is no more than 2000 ℃), forms 10-10
2The disperse distribution TiC of nm.
Can adopt the electroslag ingot casting afterwards, get rid of pore and eliminate internal flaw.Last blanking, by machining, become can setting-in tool section (being edge blade).
This be matrix with the stainless steel, by in matrix, the be evenly distributed material of disperse ultra-fine (sub-micron is to nanoscale) TiC particle of original position synthesis technique, obtain bigger raising in intensity, hardness, aspect performance such as heat-resisting, wear-resistant, corrosion-resistant, still have simultaneously higher plasticity and toughness, therefore very be suitable as the material of granules cut moving knife and so on cutting tool.Owing to do not contain rare precious metals so low price.Test shows, its room-temperature mechanical property is: б b 〉=720Mpa; б 0.2 〉=410MPa; δ 〉=20%, high temperature (700 ℃); Mechanical property: б b 〉=350Mpa; б 0.2 〉=140MPa; δ 〉=30%, and creep-resistant property (600 ℃, 260MPa); Creep rupture life L 〉=200h, high temperature (850 ℃) antioxygenic property: 100h oxidation weight gain≤4mg/cm2; Abrasion resistance properties: other improves 2 times in the part life-span than 18 8 series stainless steels, improves 1-2 doubly than the heat-resistance stainless steel that is used under the same working condition, can replace expensive cobalt-base alloys fully.Especially, the granules cut moving knife after making prolongs 30-50%. than cobalt-base alloys cutter and be confirmed in production line uses service life.
Present embodiment cutting knife agent structure as shown in Figure 1 and Figure 2, the outer round surface of cylinder-shaped body 2 axially has equidistant spiral caulking groove 3, two ends fixed support 1.In order to reach desirable cutting effect, form 2-4 ° inclination angle between caulking groove and the bus.
After main body and tool section make, with mosaic blade tool section and fixing one by one in the caulking groove 3 of main body, when making tool section and caulking groove, both fit clearance control 0.1-0.15, fill fusion material in the crack during this time, integral body is heated to the melting welding temperature, makes that melting welding is connected between edge blade and the caulking groove.
For location and the raising work efficiency that solves tool section and caulking groove, as shown in Figure 3 and Figure 4, can make one group of special welding positioning fixture 4, these anchor clamps ringwise, internal diameter embeds envelope external diameter behind the main body caulking groove greater than tool section, and the position of corresponding each caulking groove is equipped with bolt 6 respectively.During use, tighten each bolt 6 and corresponding tool section 5 can be fixed on correct position, be convenient to melting welding.After the melting welding, grinding is put the first edge on a knife or a pair of scissors and is got final product.
Experimental results show that, the granules cut moving knife operation under water made from above TiC dispersion-strengtherning stainless steel, environment temperature is near 100 ℃, corrosion-resistant and mechanical performance is all very good, and cost is more much lower than Si Taile alloy, its manufacturing process simple possible, and quality guarantees easily, therefore significantly different with existing process technology, have substantive distinguishing features and obvious improvement.
