Abstract
A kind of disclosed saw blade forges moulding process, including step is got the raw materials ready, the raw material transformation of the way, forges, ball blast, is heat-treated, subzero treatment, post processing.The delayed fracture and fatigue fracture that forge moulding process, solve saw blade under high intensity for a kind of saw blade that the present invention is provided, are not easily broken during use, and connection is reliable, improves the service life of saw blade.
Description
Technical field
The present invention relates to a kind of production method of saw blade, more particularly to a kind of saw blade forges moulding process.
Background technology
In building field, builder is frequently necessary to be cut on the materials such as plank, ceramic tile, floor tile, and commonly saws
Generally can all there be cutting particle the both sides at the saw bit matrix edge of piece, therefore cause saw blade became uneven, and in cutting, otch holds
It is flexible, so as to influence the quality of building.
The content of the invention
It is an object of the invention to provide a kind of moulding process that forges of saw blade, technical process is simpler, and manufacturing cost is relatively low, work
Skill process continuity is good, and production efficiency is high, and saw life is longer.
The technical scheme is that：A kind of saw blade forges moulding process, specifically includes following steps：
A, get the raw materials ready：Saw blade raw material is used as from 20MnTiB；
B, the raw material transformation of the way：Saw blade raw material is subjected to surface preparation, specially pickling → peeling off → lubricates → slightly pull out → pickling
→ lubrication → essence is pulled out；
C, forge：Hot forging, high frequency induction current are carried out to saw blade with 900 DEG C -1000 DEG C of temperature in high frequency induction heater
Frequency be ten thousand hertz of 2-4, then recycle punch press to coordinate and forge mould and carry out forging operation, control to forge temperature be 600 ~
650 DEG C, forge number of times and be not more than 20 times；
D, ball blast：Take out the oxide skin on saw blade bar portion surface, remaining rusty stain, chamfering burr；
E, heat treatment, then heat saw blade 8-9 hours at 460-550 DEG C, and 1080-1120 was warming up in 20-30 minutes
DEG C, kept for 20 minutes heat times, quenched with quenching oil, then the saw blade after quenching is subjected to tempering holding at 500 DEG C
30 minutes, then take out and be put into 300-320 DEG C of No. 200 solvent naphthas with oily slow cooling from tempering furnace；
F, subzero treatment, subzero treatment is carried out to the saw blade after heat treatment, and liquid nitrogen temperature is -125~-150 DEG C, subzero treatment
Time is 2-5 hours, and the isothermal time in liquid nitrogen is multiplied by 2~3min/mm2 for the cross-sectional area of saw blade, will after subzero treatment
The saw blade that temperature has gone back up to room temperature is put into heating 60-80 minutes in 100 DEG C of boiling water；
G, post processing, saw blade is fully washed, air-dry after obtain finished product saw blade.
Thin layer plant ash is covered on the impression inwall for forge mould, the Task-size Controlling of plant ash is 200-300 mesh.
Lubrication carries out coating lubrication using oilstone ash in the step b.
Beneficial effect：A kind of disclosed saw blade forges moulding process, solves prolonging for saw blade under high intensity
Fracture and fatigue fracture, are not easily broken during use late, and connection is reliable, improves the service life of saw blade.
