Description
Technical field
The invention belongs to steel rolling. field, particularly relates to the outlet of cold rolled silicon steel continuous annealing production line and cuts sampling and cut.
Background technology
The outlet of cold rolled silicon steel continuous annealing production line has one to cut, samples and cut, there is motor belt flywheel driven transfer motion power, control lower scissor blade with pneumatic clutch and band-type brake to shear and position stop, the stop place of cutting edge is inaccurate will stop the band steel run, and makes production can not continue to carry out generation accident.Along with the wearing and tearing of cutting edge and the change of working condition, adjusting the rear cutting edge stop place of side shearing is frequent thing, pneumatic pressure-release valve is cut owing to going out side, band-type brake gap, band-type brake spring is all adjustable, also all having impact to going out the position of cutting side, adjusting bad, after cutting edge is sheared, stop place is inaccurate just there will be accident.
Summary of the invention
The object of the invention is to overcome the problems referred to above and not enough and provide a kind of company move back line go out side shear after the method for adjustment of stop place, make adjustment specification, rambling adjustment process is become in good order, after shearing, stop place is accurate, shorten regulation time, easy to operate.
By to going out adjustment for many years that side cuts and according to the operation principle going out side and cut, to adjustment termination and specification be " three mark two tune " method.
Formulate method of adjustment according to going out the operation principle of cutting side, namely " three marks two are adjusted " method, demarcates cutting edge stop place successively, demarcates pneumatic pressure-release valve pressure, demarcate band-type brake gap, adjustment band-type brake spring, adjustment pneumatic pressure-release valve.
(1) cutting edge typical residence position is demarcated: operate out side and cut reset, going out side cuts as incision is cut, weight lower scissor blade is relied on to reset, crankshaft end place sealing ring ring Zhou Pingjun is split 12 parts and made marks, directly over mark be set to zero-bit, do the mark overlapped with sealing ring zero-bit directly over the crankshaft end after reset;
(2) pneumatic clutch pressure-reducing valve pressure 5-5.5MPa. is demarcated;
(3) air-actuated band brake gap 2-6mm is demarcated;
(4) band-type brake spring is adjusted: start side and cut, manually shear once, the position of stop observation cutting edge stop place and crankshaft end place mark, by adjustment band-type brake spring, the position that crankshaft end place is marked overlaps with sealing ring zero-bit; If the two occurs departing from, when bent axle mark position stop depart from sealing ring zero-bit identical with flywheel direction of rotation time, adjustment band-type brake spring nut is by spring compression, crush adjusts according to bias, namely bent axle mark often departs from sealing ring mark portion, spring nut compresses 1-2 pitch, and pitch is 2.5mm; If mark position stop depart from sealing ring zero-bit contrary with flywheel direction of rotation time, by the spring relaxation of band-type brake, quantity of margin be bent axle mark often depart from sealing ring mark portion, spring nut loosens 1-2 pitch, and pitch is 2.5mm; Restart after adjustment and side and cut manual shearing, the position of observation crankshaft end place mark, if there is deviation, repeat above method of adjustment until the nothing that overlaps with sealing ring zero-bit departs from;
(5) adjust pneumatic pressure-release valve: manual simulation connects automatically cuts 5 times, observation crankshaft end place mark is accumulative departs from sealing ring zero-bit situation, adjusts pressure-reducing valve, adjusting range 4-7MPa; When the position marked stop depart from sealing ring zero-bit identical with flywheel direction of rotation time, reduced pressure by pneumatic pressure-release valve, often depart from sealing ring mark a according to bent axle mark, pressure-reducing valve reduces pressure 0.1-0.4Mpa; If mark position stop depart from zero-bit contrary with flywheel direction of rotation time, pneumatic pressure-release valve is pressurizeed, it is a that bent axle mark often departs from sealing ring mark, pressure-reducing valve pressurization 0.1-0.4MPa, repeatedly the company of being adjusted to cuts zero-bit and sealing ring zero mark zero deflection directly over rear crankshaft end and namely adjusts end;
Due to work condition environment change and shearing wearing and tearing, continuous shear stress cumulative errors often occur, adopt the 5th step trace adjustment to depart from by quick solution.
Beneficial effect of the present invention is, applies method of adjustment of the present invention and rambling adjustment process is become in good order, and after shearing, stop place is accurate, shortens regulation time, easy to operate.
Detailed description of the invention
Formulate method of adjustment according to going out the operation principle of cutting side, namely " three marks two are adjusted " method, first sets cutting edge typical residence position, then is set by pneumatic pressure-release valve, then the setting of band-type brake gap, first adjust band-type brake spring, at adjustment pneumatic pressure-release valve.
(1) cutting edge typical residence position is demarcated: operate out side and cut reset, going out side cuts as incision is cut, weight lower scissor blade is relied on to reset, crankshaft end place sealing ring ring Zhou Pingjun is split 12 parts and made marks, directly over mark be set to zero-bit, do the mark overlapped with sealing ring zero-bit directly over the crankshaft end after reset;
(2) pressure-reducing valve of pneumatic clutch is demarcated at 5-5.5MPa;
(3) gap of air-actuated band brake is demarcated at 2-6mm;
(4) band-type brake spring is adjusted: start side and cut, manually shear once, the position of stop observation cutting edge stop place and crankshaft end place mark, by adjustment band-type brake spring, the position that crankshaft end place is marked overlaps with sealing ring zero-bit; If the two occurs departing from, when bent axle mark position stop depart from sealing ring zero-bit identical with flywheel direction of rotation time, adjustment band-type brake spring nut is by spring compression, crush adjusts according to bias, namely bent axle mark often departs from sealing ring mark portion, spring nut compresses 1-2 pitch, pitch is 2.5mm, if mark position stop depart from sealing ring zero-bit contrary with flywheel direction of rotation time, by the spring relaxation of band-type brake, quantity of margin is that bent axle mark often departs from sealing ring mark portion, and spring nut loosens 1-2 pitch, and pitch is 2.5mm; Restart after adjustment and side and cut manual shearing, observation crankshaft end place mark and the position of sealing ring zero-bit, if there is deviation, repeat above method of adjustment until the nothing that overlaps with sealing ring zero-bit departs from;
(5) adjust pneumatic pressure-release valve: manual simulation connects automatically cuts 5 times, observation crankshaft end place mark is accumulative departs from sealing ring zero-bit situation, adjusts pressure-reducing valve, adjusting range 4-7MPa; When the position marked stop depart from sealing ring zero-bit identical with flywheel direction of rotation time, reduced pressure by pneumatic pressure-release valve, often depart from sealing ring mark a according to bent axle mark, pressure-reducing valve reduces pressure 0.1-0.4Mpa; If mark position stop depart from zero-bit contrary with flywheel direction of rotation time, pneumatic pressure-release valve is pressurizeed, it is a that bent axle mark often departs from sealing ring mark, pressure-reducing valve pressurization 0.1-0.4MPa, repeatedly the company of being adjusted to cuts zero-bit and sealing ring zero mark zero deflection directly over rear crankshaft end and namely adjusts end;
Due to work condition environment change and shearing wearing and tearing, continuous shear stress cumulative errors often occur, adopt the 5th step trace adjustment to depart from by quick solution.
Apply method of adjustment of the present invention and rambling adjustment process is become in good order, after shearing, stop place is accurate, shortens regulation time, easy to operate.
