Abstract
The invention discloses a kind of manufacture method of sand saw blade, the preparation method of sand saw blade is including as follows：1) saw blade raw material is collected；2) heat；3) roll；4) cooling treatment；6) bulk pruning；7) tension straingtening；8) fine pruning；9) punching；Hole is punched through respectively at the above-mentioned semi-finished product sand saw blade both ends being cut to after cut lengths using punch press, and sand saw blade is made.It is an object of the invention to provide the manufacture method using waste and old superseded rail for a kind of sand saw blade of raw material.
Description
Technical field
The present invention relates to a kind of manufacture method of sand saw blade.
Background technology
The capital equipment of the big plate Cutting indexes of granite is using steel sand as abrasive material, by one group of sand saw blade as saw at present
Cutter.
The content of the invention
Manufacture method it is an object of the invention to provide the waste and old superseded rail of use for a kind of sand saw blade of raw material,
The present invention is that technical scheme is used by solving above-mentioned technical problem：
A kind of manufacture method of sand saw blade, it is characterised in that：The preparation method of the sand saw blade includes as follows：1) receive
Collect saw blade raw material；2) heat；3) roll；4) cooling treatment；6) bulk pruning；7) tension straingtening；8) fine pruning；9) punching；Utilize
Punch press is punched through hole respectively at the above-mentioned semi-finished product sand saw blade both ends being cut to after cut lengths, and sand saw blade is made.
Its advantage of the present invention is that its chemical backbone material of the sand saw blade of technique system manufacture is controllable, and the first day of the lunar month can be chased after by having
Property, internal that fatigue crack is not present, not easy to break, sand saw blade anti-wear performance is good, and chemical composition can ensure, in same process
Under the conditions of the sand saw blade hardness that produces it is identical.
Embodiment
A kind of manufacture method of sand saw blade, the preparation method of sand saw blade is including as follows：1) saw blade raw material is collected；Selection
The useless crop at the both ends of rail factory rolling U75V rail 3, it is 1m that useless crop 1 is cut into length；The chemical analysis of useless crop is：C,
0.71~0.80%, Si, 0.50~0.80%, Mn, 0.70~1.05%, P ＜ 0.030%, S ＜ 0.030%, V, 0.04~
0.12%；The rail undercutting of useless crop is fallen with CUT, using rail bottom as sand saw blade raw material；2) at heating
Reason：Above-mentioned rail bottom is pushed into heating furnace and heated, above-mentioned rail bottom is heated to 1110-1200 DEG C；3) roll：By above-mentioned heating
Rail bottom by rolling 9 passages, roll into thickness 4.2mm, width 100mm semi-finished product sand saw blades；4) cooling treatment；Will rolling
Complete semi-finished product sand saw blade is sent to natural cooling on cold bed；6) bulk pruning；It will be sawed with cutter through overcooled semi-finished product sand
Saw blade bulk pruning is cut；7) tension straingtening；Stretching-machine is to the semi-finished product sand saw blade tension straingtening after bulk pruning；8) fine pruning；Use cutter
Semi-finished product sand saw blade after stretching is cut to cut lengths 3500mm；9) punching；Using punch press cut lengths is cut to above-mentioned
Semi-finished product sand saw blade both ends afterwards are punched through hole respectively, and sand saw blade is made.The sand saw blade made of this method, tensile strength
>=1100MPa, elongation percentage 9~11%, 32~38HRC of hardness.
