Description
Technical Field
The invention relates to the technical field of Simon disk shears, in particular to a method for calibrating a shearing edge of the Simon disk shears.
Background
The Simon circle shear is a turret type, is provided with four circle shears and four scrap shears, is arranged on a rotating frame which can rotate 180 degrees, and automatically sets and controls the gap between the ASC-type shear blades. The disc shear and the scrap chopper are integrated into a unit, a set of rotating platforms are arranged on the operating side and the driving side, and 2 sets of disc shears and 2 sets of complete scrap choppers (1 set for standby) are arranged on each platform. Once waste accumulation occurs in the chute between the disc shear and the chopper, the disc shear and the chopper on the other side can simultaneously rotate to the working position. The standby equipment can be immediately put into use, the continuous operation of the production line is ensured, and the waste edges in the chute can be removed at the moment. Because the circle shear and the breaking shear are arranged on the same rotary platform, the chute between the circle shear blade and the breaking shear blade is made into a whole, and the possibility of waste edge blockage is reduced. The rotation of the turntable is accomplished by a gear motor. After the platform rotates, the platform is clamped at a working position in an electromechanical mode.
According to a preset table in the second level of the computer, the blade gap/overlapping amount of the disc shear and the gap of the scrap shear can be automatically adjusted to any working position. The disc shear is of the driverless type. The gap and the overlapping amount of the shear blades are adjusted by a special electric eccentric shaft. Aiming at different specifications of strip steel, the other eccentric shaft is used for further correcting the gap, and the rapid opening is realized.
The following disadvantages exist: because the eccentric shaft adjusts the gap of the shear blade, the overlapping gap changes along with the change of the side gap, and an overlapping value is obtained. The overlapping gap is not accurately calibrated by a normal zero calibration step, so that the trimming quality is influenced; and the existing trimming gap parameter table is used for trimming, and the trimming quality can not meet the field requirement.
Disclosure of Invention

In order to achieve the purpose, the invention adopts the following technical scheme:
a method for calibrating shear blades of a Simon circle shear specifically comprises the following steps:
1) Setting a side gap of 0.4mm as an overlap gap calibration datum point;
2) Firstly, calibrating a side clearance:

after the clearance is accurate, the side clearance calibration is finished;
3) And calibrating the overlapping clearance:
adjusting the side clearance to 0.4mm, adjusting the overlapping clearance to-0.2 mm, starting to measure, measuring the overlapping amount by using clearance gauges with different thicknesses, and calibrating by using the thickness of the clearance gauge after the clearance gauge is inserted and unplugged;
after the overlapping gap is automatically adjusted to 0mm, and the measuring gap is accurate, the calibration of the overlapping gap is completed;
4) Optimizing a Simmark trimming gap parameter table:
A. increasing the ratio of the shearing zone to the fracture zone of the circle shear, wherein the ratio of the shearing zone to the fracture zone of DC03 and DC04 is 1:2, adjusting to 1:1; the ratio of DC05, DC06 shear to break regions is from 1:2, adjusting to 2:1;
B. and reducing the side clearance value of the disc shear to 0.1-0.2 mm.
As a further improvement of the invention, the step 1) of side clearance four-point measurement ensures that the four-point measurement values of the manual disc cutting edge are the same.
Compared with the prior art, the invention has the beneficial effects that:
the method firstly searches a calibration reference point, and finds that when the eccentric shaft adjusts the gap of the shear blade, the overlapping gap changes along with the change of the side gap through multiple tracking data acquisition, but when the side gap is 0.4mm, the overlapping gap does not change to have an overlapping value. A side gap of 0.4mm is the overlap gap calibration reference point. Then, firstly calibrating the side gap, then calibrating the overlapping gap, and then optimizing a Simmak trimming gap parameter table by combining the actual trimming quality, so that the trimming quality of the soft material at the DC 03-DC 06 level meets the quality requirement.

[ examples ] A method for producing a compound
A method for calibrating shear blades of a Simon circle shear specifically comprises the following steps:
1. finding a calibrated reference point
The data are tracked and collected for many times, and the overlapping gap is changed along with the change of the side gap when the eccentric shaft adjusts the gap of the shear blade, but the overlapping value is not changed when the side gap is 0.4 mm. A side gap of 0.4mm is the overlap gap calibration reference point.
2. Calibrating the side clearance first
Firstly, adjusting the side clearance to 0.2mm, then measuring by using a feeler gauge, and calibrating after the feeler gauge is inserted and pulled out without obstruction; after the side clearance is adjusted to 0.1mm again, the clearance gauge is used for measuring, and the clearance gauge is calibrated after being inserted and pulled out without obstruction; and after the clearance is accurate, the side clearance calibration is finished. The side clearance needs four-point measurement, and the hand-operated disc shear blade ensures that the four-point measurement values are the same.
3. Calibrating an overlap gap
The side clearance is adjusted to 0.4mm, the overlapping clearance is adjusted to-0.2 mm, the measurement is started, the clearance is not adjusted manually accurately, clearance gauges with different thicknesses are used for measuring the overlapping amount, and the thickness of the clearance gauge is calibrated after the clearance gauge is inserted and pulled out without obstruction. After the overlapping clearance is automatically adjusted to 0mm, the measuring clearance is accurate, and then the overlapping clearance calibration is completed.
4. In the method, a Simmark trimming gap parameter table is optimized by combining actual trimming quality, so that the soft material trimming quality of DC 03-DC 06 level meets the quality requirement.
(1) The value of the overlapping gap of the circle shear is increased, namely the proportion of the shearing area to the fracture area of the circle shear is increased, and the proportion of the shearing area to the fracture area of the circle shear is increased from 1:2, adjusting to 1:1; the ratio of DC05, DC06 shear to fracturant region is from 1:2, adjusting to 2:1.
(2) And the side clearance value of the disc shear is reduced to 0.1-0.2 mm, and the trimming quality of the strip steel is ensured.
The quality of the cut edge of the strip steel before optimization is shown in figure 1, and the quality of the cut edge of the strip steel after optimization is shown in figure 2.
