Abstract
The invention provides a kind of production technology of cutting edge, comprise the following steps：（1）, for the cutting edge that loses flesh, must be matched according to the situation selection that loses flesh the carrying out that size is more or less the same that lose flesh；During grinding periphery, two panels pairing cutting edge is had to look for before grinding every time, pairing cutting edge diameter is more or less the same in 1 millimeter；I.e. outside dimension must be identical；（2）, clamping, no more than 1 millimeter；I.e. outside dimension must be identical；（3）, cylindrical grinding：0.01mm closely is less than to amount per knife, cooling is sufficient, corase grind is refined to finished product after removing 0.25mm from new finishing emery wheel；（4）, cylindrical grinding.The production technology of cutting edge of the invention, the problems such as the cutting edge surface produced is not in pit projection, burr, crackle, so as to improve cutting edge quality, extends cutting edge service life, reduces production cost.
Description
Technical field
The present invention relates to circle shear technical field, more particularly to disc shear edge production technology.
Background technology
The rotates blade of circle shear allows to be changed in the case where line is not stopped, and has special equipment permission for cutting edge
The mechanical clearance of cutting edge is adjusted when being sheared to strip.The disk of existing disc shear edge processing technology production
Rough surface is cut, and easily there are the defects such as pit projection, burr, crackle in cutting edge surface.
The content of the invention
The problems such as there is pit projection, burr, crackle to solve cutting edge surface, the invention provides a kind of life of cutting edge
Production. art.
The technical scheme that is used to achieve the above object of the present invention is：A kind of production technology of cutting edge, including following step
Suddenly：
（1）, for the cutting edge that loses flesh, must be matched according to the situation selection that loses flesh the carrying out that size is more or less the same that lose flesh；Grinding periphery
When, two panels pairing cutting edge is had to look for before grinding every time, pairing cutting edge diameter is more or less the same in 1 millimeter；I.e. outside dimension is necessary
It is identical；
（2）, clamping, no more than 1 millimeter；I.e. outside dimension must be identical；
（3）, cylindrical grinding：Closely be less than 0.01mm to amount per knife, cooling is sufficient, corase grind go after 0.25mm from new finishing emery wheel refine to
Finished product；
（4）, cylindrical grinding.
The step（1）And step（2）In, outside dimension precision is 0-0.1mm.
The step（3）In, also including removing flash removed, demagnetize.
The step（4）Middle roundness tolerance 0.005-0.01mm, surface roughness：Ra0.8-0.4mm.
The production technology of cutting edge of the invention, the cutting edge surface produced is not in that pit projection, burr, crackle etc. are asked
Topic, so as to improve cutting edge quality, extends cutting edge service life, reduces production cost.
Specific embodiment
The production technology of cutting edge of the invention, comprises the following steps：
（1）, for the cutting edge that loses flesh, must be matched according to the situation selection that loses flesh the carrying out that size is more or less the same that lose flesh；Grinding periphery
When, two panels pairing cutting edge is had to look for before grinding every time, pairing cutting edge diameter is more or less the same in 1 millimeter；I.e. outside dimension is necessary
Identical, outside dimension precision is 0-0.1mm；
（2）, clamping, no more than 1 millimeter；I.e. outside dimension must be identical；
（3）, cylindrical grinding：Closely be less than 0.01mm to amount per knife, cooling is sufficient, corase grind go after 0.25mm from new finishing emery wheel refine to
Finished product, flash removed, demagnetization.
（4）, cylindrical grinding, roundness tolerance 0.005-0.01mm, surface roughness：Ra0.8-0.4mm.
The rotates blade of circle shear allows to be changed in the case where line is not stopped, and has special equipment permission for cutting edge
The mechanical clearance of cutting edge is adjusted when being sheared to strip, two power driven systems allow the cutting edge of edge in the water pruned
Gentle vertical direction alone be adjusted gap.The cutting edge of replacing circle shear is simple and takes around 1 minute, readily removable/
More allowing blade replacement is possible to be carried out by hydraulic nut, and the waste material for also being scaled off using drive bearing both sides is directly entered ash can.
The present invention is described by embodiment, and those skilled in the art know, is not departing from spirit of the invention
In the case of scope, various changes or equivalence replacement can be carried out to these features and embodiment.In addition, in religion of the invention
Lead down, these features and embodiment can be modified to adapt to particular situation and material without departing from essence of the invention
God and scope.Therefore, the present invention is not limited to the particular embodiment disclosed, and falls with claims hereof
In the range of embodiment belong to protection scope of the present invention.
