Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1-3, an FMM metal sheet thinning apparatus includes a thinning region 1, a buffer region 2, and a discharging region 3, where the FMM metal sheet passes through the thinning region 1 under the driving of a transmission mechanism 4, the FMM metal sheet is continuously thinned through the thinning region 1, the thinning region 1 includes a first rolling mechanism 11 and a second rolling mechanism 12, which are sequentially disposed, the FMM metal sheet is stably transmitted along the middle position of the first rolling mechanism 11 and the second rolling mechanism 12, and is continuously thinned through more than one first rolling mechanism 11, and then is rolled and thinned through the second rolling mechanism 12.
The thinning device also comprises a main control system electrically connected with the first control system and the second control system; the first rolling mechanism 11 is electrically connected with a first control system, and more than one first rolling mechanism 11 is arranged at equal intervals along the conveying direction of the FMM metal sheet; each first rolling mechanism 11 further comprises a load meter 102, a tension meter 103 and a thickness gauge 104 which are sequentially arranged, and the load meter 102, the tension meter 103 and the thickness gauge 104 are all arranged between two adjacent first rolling mechanisms 11 or between the second rolling mechanism 12 and the adjacent first rolling mechanisms 11.
After the FMM metal sheet is thinned by a first rolling mechanism 11, a load meter 102, a tension meter 103 and a thickness gauge 104 of the first rolling mechanism 11 detect the elasticity, tension, thickness and other parameters of the FMM metal sheet, and feed the detected information back to a first control system, the first control system regulates and controls the rotation speed, clamping degree and the like of a rolling wheel 101 of the first rolling mechanism according to the received parameter information, and simultaneously regulates and controls the rotation speed, clamping degree and the like of a rolling wheel 101 of the first rolling mechanism 11 or a rolling wheel 101 of a second rolling mechanism adjacent to the first rolling mechanism 11, so that the FMM metal sheet is ensured to be stably conveyed and accurately thinned under the driving of a conveying mechanism.
The second rolling mechanism 12 is electrically connected with a second control system, and the second rolling mechanism 12 further comprises a thickness gauge 104, a tensiometer 103 and a flatness gauge 105 which are sequentially arranged; the thickness gauge 104, the tension gauge 103 and the flatness gauge 105 are located between the second rolling mechanism 12 and the buffer area 2.
Each inner rolling wheel 101 close to the FMM metal sheet in the first rolling mechanism 11 is tangent to one adjacent outer rolling wheel 101; each inner rolling wheel 101 of the second rolling mechanism 12 close to the FMM metal sheet is tangent to two adjacent outer rolling wheels 101.
After the FMM metal sheet is rolled and thinned by more than one first rolling mechanism 11, the FMM metal sheet continues to advance under the drive of a transmission mechanism, is rolled and thinned by a second rolling mechanism 12, and is rolled and thinned by rolling wheels 101 of the second rolling mechanism, a thickness gauge 104, a tension gauge 103 and a flatness gauge 105 of the second rolling mechanism 12 detect parameters such as thickness, tension and flatness of the FMM metal sheet, and feed detected information back to a second control system, the second control system adjusts the rotating speed, clamping degree and gap or contact condition between the rolling wheels 101 of the second rolling mechanism according to the received parameter information, so that the inner layer rolling wheel 101 of the second rolling mechanism 12 can form force transmission with two rolling wheels 101 tangent to the inner layer rolling wheel, specifically, the resultant force of the inner layer rolling wheel 101 to the two tangent outer layer rolling wheels 101 can be equally divided into two component forces, by arranging the rolling wheels 101 of the second rolling mechanism 12 in a fan shape, the multi-layer rolling wheels 101 can disperse the counter force, so that the stress reduction of the main driving rolling wheels 101 close to the FMM metal sheet is reduced.
The first rolling mechanism 11 and the second rolling mechanism 12 both comprise an even number of rolling wheels 101 which are symmetrically arranged about a horizontal plane where the FMM metal sheet is located; the rolling wheels 101 of the first rolling mechanism are distributed in a linear shape, and the rolling wheels 101 of the second rolling mechanism are distributed in a symmetrical fan shape.
The diameter of the first rolling mechanism rolling wheel 101 and the diameter of the second rolling mechanism rolling wheel 101 are gradually increased from one end close to the FMM metal sheet to one end far away from the FMM metal sheet; the diameter of the inner layer rolling wheel 101 close to one end of the FMM metal sheet is 1.25-1.65 times of the diameter of the adjacent outer layer rolling wheel 101.
The rolling wheels 101 of the first rolling mechanism are distributed in a linear shape, so that the diameter of the rolling wheels 101 of the first rolling mechanism is gradually increased from one end close to the FMM metal sheet to one end far away from the FMM metal sheet; meanwhile, the rolling wheels 101 of the second rolling mechanism are distributed in two symmetrical fan shapes, so that the diameter of the rolling wheels 101 of the second rolling mechanism is gradually increased from one end close to the FMM metal sheet to one end far away from the FMM metal sheet. Because the FMM metal thin plate is processed by the plate with extremely thin and hard thickness, when the FMM metal thin plate processed by the plate is rolled and thinned, the smaller the diameter of the rolling wheel 101 in contact with the FMM metal thin plate is, the better the FMM metal thin plate is, but because the diameter of the rolling wheel 101 in contact with the FMM metal thin plate is small, the FMM metal thin plate is easy to deform when the FMM metal thin plate is rolled and thinned, the rolling wheels 101 with gradually increasing diameters are sequentially arranged on the outer side of the FMM metal thin plate for supporting, and the deformation of the inner layer rolling wheel 101 in contact with the FMM metal thin plate can be eliminated to a great extent through the mutual matching use of the rolling wheels 101 of each layer, so that the continuous thinning effect of the FMM metal thin plate is optimized, and.
In addition, the diameter of the inner layer rolling wheel 101 near one end of the FMM metal sheet is defined to be 1.25 to 1.65 times, and most preferably 1.4 times, the diameter of the adjacent outer layer rolling wheel 101. When the difference between the wheel diameters of the inner layer rolling wheel 101 and the outer layer rolling wheel 101 is large, the service lives of the first rolling mechanism 11 and the second rolling mechanism 12 are greatly influenced in terms of fatigue; when the difference in wheel diameter between the inner layer rolling wheel 101 and the outer layer rolling wheel 101 is small, the structures of the first rolling mechanism 11 and the second rolling mechanism 12 become complicated, and timely response and adjustment are not facilitated, so that the thinning effect of the FMM metal sheet is affected.
The rolling wheels 101 of the first rolling mechanism 11, which are positioned above or below the FMM metal thin plate, are respectively provided with 3-4 layers from one end close to the FMM metal thin plate to one end far away from the FMM metal thin plate;
the rolling wheels 101 of the second rolling mechanism 12, which are located above or below the FMM metal sheet, are respectively provided with 3-4 layers from one end close to the FMM metal sheet to one end far away from the FMM metal sheet.
By respectively limiting the rolling wheels 101 of the first rolling mechanism 11 and the second rolling mechanism to be 3-4 layers, the stress of the inner-layer rolling wheel 101 in contact with the FMM metal sheet can be reduced by dispersing the angle of the reaction force from the multi-layer rolling wheel 101; and from the angle such as compression ratio or support stability, set up 3 ~ 4 layers, can make first rolling mechanism 11, second rolling mechanism 12 can carry out steady attenuate to FMM sheet metal to guarantee the attenuate precision of FMM sheet metal.
The main control system is used for adjusting the tension degree of the FMM metal sheet wound on each tension wheel 201 of the buffer area.
The buffer area 2 comprises more than one tension wheel 201 which is movably arranged in a continuous V shape, and the FMM metal thin plate is wound on the tension wheel 201 of the buffer area in a continuous V shape.
After the FMM metal sheet is continuously thinned by the first rolling mechanism 11 and the second rolling mechanism 12 of the thinning zone 1, the thickness gauge 104, the tension gauge 103 and the flatness gauge 105 of the second rolling mechanism 12 detect the thickness, the tension and the flatness of the FMM metal sheet, on one hand, the detected information is transmitted to the second control system, so that the second control system regulates and controls the second rolling mechanism 12 according to the detected information, on the other hand, the detected information is transmitted to the main control system, the main control system adjusts the position of each tensioning wheel 201 of the buffer zone 2 according to the detected information and the information transmitted by the first rolling mechanism 11, namely, adjusts the tightness of the FMM metal sheet wound on each tensioning wheel 201 in a continuous V shape, and further realizes the adjustment of the surface tension, the flatness, the thickness, the prestress and the like of the FMM metal sheet, the FMM metal sheet can meet the thinning requirement, and the thinning qualification rate of the FMM metal sheet and the production quality of the FMM metal sheet are improved.
The discharge section 3 comprises a pair of pinch wheels 301 arranged end to end, a plate 302 between the two pairs of pinch wheels, and a CCD detector 303 placed above the FMM sheet metal which is transported along the upper surface of the plate 302.
The FMM metal sheet is driven by the conveying mechanism to pass through the clamping wheels 301 arranged in pairs, the FMM metal sheet is located between the two clamping wheels 301, and the FMM metal sheet is separated through powerful clamping of the two clamping wheels 301, but the FMM metal sheet is not directly cut off, so that continuous conveying of the FMM metal sheet is ensured; meanwhile, the FMM metal sheet is conveyed on the upper surface of the flat plate 302 between the two pairs of clamping wheels, the CCD detector 303 is arranged above the FMM metal sheet, the thinned FMM metal sheet is subjected to final qualified detection, and the thinning processing quality of the FMM metal sheet is ensured.
The main control system is an existing computer control system, the first control system and the second control system are controllers of Mitsubishi PAC (programmable automatic controller) MELSEC IQ-R series, and can be adjusted in time in the thinning process through mutual matching and cooperative regulation among the main control system, the first control system and the second control system, so that the thinning effect of the FMM metal sheet is improved, the thinning precision of the FMM metal sheet is improved, parameters such as thickness, tension, flatness and prestress of the FMM metal sheet can be further regulated and controlled after the FMM metal sheet is thinned, and the thinning quality of the FMM metal sheet is further improved.
Referring to fig. 4, the method for controlling the thickness reduction of the FMM metal thin plate thinning apparatus includes the following steps:
(1) arranging a conveying mechanism at the head end of the thinning area and the tail end of the discharging area, and arranging the FMM metal sheet at the middle positions of the first rolling mechanism and the second rolling mechanism, so that the FMM metal sheet sequentially passes through the thinning area, the buffer area and the discharging area under the driving of the conveying mechanism;
(2) after the FMM metal sheet is rolled and thinned by the first rolling mechanism, a load meter, a tensiometer and a thickness gauge of the first rolling mechanism detect the FMM metal sheet which is rolled and thinned by the first rolling mechanism;
the first control system adjusts the rolling wheel gap and the rolling wheel curvature of the first rolling mechanism according to the detected information and feeds back the rolling wheel gap and the rolling wheel curvature to the main control system;
in the step (2), after the load gauge, the tensiometer and the thickness gauge of the first rolling mechanism feed detected information back to the first control system, the first control system compares the measured tension value and thickness value with a standard tension value and a standard thickness value preset by the first control system, and issues an instruction to the first rolling mechanism according to a comparison result, and the first rolling mechanism adjusts a gap between adjacent rolling wheels and the curvature of each rolling wheel according to the received instruction;
meanwhile, the load meter, the tensiometer and the thickness gauge of the first rolling mechanism also feed detected information back to a first control system of an adjacent first rolling mechanism or a second control system of an adjacent second rolling mechanism, the first control system regulates and controls the rotating speed of rolling wheels, gaps among the rolling wheels and the bending degree of each rolling wheel of the next first rolling mechanism, further realizes regulation and control of the thinning condition of the FMM metal sheet entering the first rolling mechanism or the second rolling mechanism, and further ensures the thinning precision and the thinning effect of the FMM metal sheet.
(3) After the FMM metal sheet is rolled and thinned by the second rolling mechanism, a thickness gauge, a tensiometer and a flatness measuring instrument of the second rolling mechanism detect the FMM metal sheet which is rolled and thinned by the second rolling mechanism;
the second control system adjusts the rolling wheel gap, the rolling wheel curvature and the rolling wheel force transmission of the second rolling mechanism according to the detected information and feeds back the adjustment to the main control system;
in the step (3), after the thickness gauge, the tensiometer and the flatness gauge of the second rolling mechanism feed detected information back to the second control system, the second control system compares the measured tension value, thickness value and flatness value with a standard tension value, a standard thickness value and a standard flatness value preset by the second control system, and issues an instruction to the second rolling mechanism according to a comparison result, and the second rolling mechanism adjusts the gap between adjacent rolling wheels, the curvature of each rolling wheel and the transmission of force between two adjacent layers of rolling wheels according to the received instruction;
meanwhile, the thickness gauge, the tensiometer and the flatness measuring instrument of the second rolling mechanism feed detected information back to the main control system, and the main control system coordinates the received detection information and the information detected by the first control system to adjust the FMM metal sheet wound on the tension wheel.
The rolling wheels of the first rolling mechanism and the second rolling mechanism are arranged on the wheel shaft, and when the adjustment and control are carried out, the two symmetrically arranged rolling wheels are adjusted towards opposite directions. When the distance between the two symmetrically arranged rolling wheels is too large and needs to be adjusted, pressure F can be simultaneously applied to wheel shafts close to the two ends of the rolling wheels, so that the two rolling wheels are close to each other, and the aim of reducing the distance between the two rolling wheels is fulfilled; when the distance between the two symmetrically arranged rolling wheels is too small and needs to be enlarged, the tension S can be simultaneously applied to the positions, close to the two ends, of the wheel shaft, so that the two rolling wheels are far away from each other, and the purpose of increasing the distance between the two rolling wheels is achieved.
(4) The main control system coordinately controls each tensioning wheel of the buffer area to move up or down, so as to adjust the tension, thickness and flatness of the FMM metal sheet;

(5) The CCD detector detects and judges the FMM metal sheet after continuous thinning;
when the FMM metal sheet is qualified, the thinning device continues to thin the next section of FMM metal sheet;
when the FMM metal sheet is unqualified in machining, the thinning device stops working and automatically judges whether the prestress of the rolling wheel is too large or too small, and a worker adjusts parameters of the first control system, the second control system and the main control system according to a judgment result and then starts working.
