Description
Present patent application is to be directed to Application No.：2015105013411 divisional application, the applying date of original application
For：2015-08-14, invention and created name are：A kind of manufacture method of high-precision laser bonding machine cutting edge.
Technical field
The present invention relates to mechanical bit processing technique field, is cut more specifically to a kind of high-precision laser bonding machine
Sword.
Background technology
The typical cold-rolling process route that China's steel industry is in leading position at present is：Converter smelting-external refining-
Breaking down cogging-hot continuous rolling-pickling-cold rolling-annealing-smooth-zinc-plated (tin)-is into product.Typical cold-rolling process herein
In, band welding equipment is essential.In the process of running, leading strip must be welded with rear row strip, just can guarantee that
Production line is worked continuously.And laser welding be by the focusing laser beam projects with high power density be soldered material on,
Interacted by light beam and soldered material, luminous energy, which is absorbed by material, is converted into heat energy, so that the welding side of melt material
Method.Laser welding heat affected area is small, and material deformation is small, without subsequent handling processing；It is real meanwhile laser beam is easy to be oriented to, focused on
Existing all directions conversion.Therefore laser welding production efficiency is high, and crudy is reliable and stable, and economic benefit and social benefit are good, quilt
It is widely used in cold-rolling process.
At present, the laser welding apparatus used in cold-rolling process is laser welder, and laser welder has advantages below：1st, weld
Connect that speed is fast, deformation is small；2nd, power density is high, and weld penetration is big, and depth-to-width ratio is up to 5；3rd, control easy to automate；4th, weld
Narrow heat affected area very little is stitched, seam organization is uniform.Laser welder includes scissors, protection valve and welding wheel etc., and scissors have two groups,
Each group of scissors are made up of upper and lower two panels cutting edge.The welding quality of laser welder has direct relation with the precision of scissors cutting edge, and
It is cutting edge linearity and the cutting edge depth of parallelism to evaluate the main index of cutting edge precision.Meanwhile laser welder is mainly used in automobile, electricity
The welding qualities such as son, biomedicine have the high-technology field of high requirement, are characterized in that welded blank hardness is larger, no
There can be the problems such as weld seam to occur, therefore, during laser welder sheet material to have higher shearing quality, the hardness of cutting edge is also carried
Higher requirement is gone out.But laser welder cutting edge in the market often can not at two aspects of linearity and the depth of parallelism
Further lifted, therefore can not further improve the shearing quality of shearing workpiece, and then constrain laser welder weldering significantly
Connect the further lifting of quality, it is difficult to meet active demand of the high-technology field to high welding quality.
On improving the linearity of long blade, existing related technical scheme discloses in the prior art：Such as patent publication No.：
The A of CN 103464999, publication date：On December 25th, 2013, this application case disclose a kind of method for manufacturing overall long blade,
Its step is：1) raw material of overall long blade prepare：Pulling forging is carried out to rough forging, its forging ratio is 1：3；2) forge
The annealing of blank：860~870 DEG C are warming up to, is incubated 4~6 hours, then air cooling rises again to 350~400 DEG C after air cooling
Temperature arrives 700-720 DEG C, is incubated 2~3 hours；3) roughing of rough forging：Line and drilling machine punching, during line pitch-row control be
L+0.2mm, wherein L are the pitch-row requirement of overall long blade finished product；4) heat treatment of overall long blade：It is increased to after preheating three times
1020~1040 DEG C, 50~55 minutes are incubated, oil quenching of being come out of the stove after insulation；5) deep processing of overall long blade.This application case manufactures
The mounting hole pitch-row of obtained overall long blade finished product ensure that the linearity, vertical of overall long blade within controlled range
Degree and excellent wearability and shock resistance, still, can not make significantly to the linearity and the depth of parallelism of overall long blade
Lifting, constrain the further lifting of shearing workpiece shearing quality.
In summary, existing laser welder cutting edge how is overcome in skill existing for two aspects of lifting linearity and the depth of parallelism
Art bottleneck, it is to perplex the problem of tool sharpening industry for many years.
