Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of stamping waste processing, in particular to a stamping waste automatic collection system of an intelligent steel drum production line. BACKGROUND

[0002] The cover stamping of the steel drum production line is a core link in steel drum manufacturing, which is complex and technology-intensive. The cover stamping usually uses steel plates as raw materials and is formed through multiple processes. First, the steel coil is cut into appropriate size plates by a shearing machine, and then the blanking, drawing, punching and other operations are completed at one time on a press using a compound die.

[0003] The stamping waste collection technology of the existing steel drum production line takes traditional mechanical processing as the core, realizes waste removal through natural outflow, ejection device or chopping process, and improves the utilization rate of waste materials by combining with sleeve cutting technology, elastic positioning pin and other equipment modification. However, this technology still faces significant bottlenecks: waste jamming leads to high equipment failure rate, low material utilization rate, and strong dependence on manual intervention, such as regular cleaning, equipment adjustment and quality sampling, which all require manual intervention.

[0004] Although some enterprises have optimized production continuity by integrating and designing buffer units of automatic production lines, the overall intelligent level is insufficient, lacking real-time online monitoring and closed-loop feedback mechanism, making it difficult to adapt to multi-variety and small-batch production mode. The waste collection in the steel drum production field is still mainly based on chute transmission and manual cleaning, and the processing efficiency and quality control lag significantly, which has become a key short board restricting the flexible upgrading of the industry.

[0005] Chinese patent application publication No. CN114589509A discloses a waste recovery equipment for stainless steel strip production, which comprises a device box, a discharge rack and a material conveying rack. The material conveying rack is fixed and penetrates through the middle part of the device box on the front and rear sides, and the discharge rack is fixed and installed on the front and rear sides of the device box. The device box is fixedly installed with a collecting box on the lower side of the discharge rack, and a gas conveying mechanism is fixedly installed on the upper side of the device box. The gas conveying mechanism can be fixedly installed inside the device box. A supporting mechanism is fixedly installed in the middle part of the inner side of the device box, and a steel strip cutting mechanism is fixedly installed on the upper side of the supporting mechanism. The steel strip cutting mechanism is fixedly installed with a waste cutting mechanism on the front and rear sides, and the waste cutting mechanism is fixedly connected with a material pushing mechanism on the left side. The polished steel strip is tightly fitted with a polishing mechanism on the front and rear sides, and the polishing mechanism is fixedly connected with the steel strip cutting mechanism. The waste can be cut and collected, and the steel strip can be polished and cooled.

[0006] It can be seen that the above technical scheme does not detect the curvature, thickness change and edge deformation of the waste in real time, cannot dynamically adjust the cutting and flattening process parameters according to the actual deformation degree of the waste, and does not consider the thickness standard deviation and interlayer gap uniformity of the processed waste, affecting process parameter optimization, thereby causing the problem of low waste recovery efficiency. SUMMARY

[0007] Therefore, the present application provides a stamping waste automatic collection system of an intelligent steel drum production line to overcome the problem in the prior art that the curvature, thickness change and edge deformation of the waste are not detected in real time, the cutting and flattening process parameters cannot be dynamically adjusted according to the actual deformation degree of the waste, and the thickness standard deviation and interlayer gap uniformity of the processed waste are not considered, affecting process parameter optimization, thereby causing the problem of low waste recovery efficiency.

[0022] the second cutting mode is to control the shearing machine to cut the waste;

[0023] the third cutting mode is to start the infrared heating belt to soften the waste and then control the shearing machine to cut the softened waste.

[0024] Further, the mode determining module determines the flattening mode of the waste after cutting according to the edge deformation representation value of the waste, wherein,

[0025] if the edge deformation representation value is less than a first preset edge deformation representation value, the magnetic attraction conveyor is controlled to perform edge flattening;

[0026] if the edge deformation representation value is greater than or equal to the first preset edge deformation representation value and less than a second preset edge deformation representation value, the roller press is controlled to perform edge flattening;

[0027] if the edge deformation representation value is greater than or equal to the second preset edge deformation representation value, the roller press is controlled to perform edge flattening and then the magnetic attraction conveyor is controlled to perform edge flattening;

[0028] The edge deformation characterization value is a ratio between a vertical distance between the highest point of the waste edge and a plane of the magnetic attraction conveying belt and a preset vertical distance.

[0029] Further, the control module determines whether the flatness of the waste meets the preset standard according to a thickness standard deviation value of the waste on the collecting rack, wherein,

[0030] If the thickness standard deviation value is less than a first preset thickness standard deviation value, it is determined that the flatness of the waste meets the preset standard.

[0031] If the thickness standard deviation value is greater than or equal to the first preset thickness standard deviation value and less than a second preset thickness standard deviation value, it is determined that the flatness of the waste does not meet the preset standard, and the flatness of the waste is determined again according to a layer gap uniformity characterization value of the waste.

[0032] If the thickness standard deviation value is greater than or equal to the second preset thickness standard deviation value, it is determined that the flatness of the waste does not meet the preset standard, and a processing mode of the flatness of the waste not meeting the preset standard is determined according to a surface waviness of the waste.

[0033] The thickness standard deviation value is a standard deviation of thicknesses of the waste on the collecting rack.

[0034] Further, the control module determines whether the flatness of the waste meets the preset standard according to a layer gap uniformity characterization value of the waste on the collecting rack, wherein,

[0035] If the layer gap uniformity characterization value is less than a preset layer gap uniformity characterization value, it is determined that the flatness of the waste meets the preset standard.

[0036] If the layer gap uniformity characterization value is greater than or equal to the preset layer gap uniformity characterization value, it is determined that the flatness of the waste does not meet the preset standard, and a roller pressure of the roller press is increased according to a difference between the layer gap uniformity characterization value and the preset layer gap uniformity characterization value.

[0037] Further, the layer gap uniformity characterization value is a standard deviation of layer gap distances of the waste.

[0038] Further, the control module sets a plurality of pressure increasing modes for the increase of the roller pressure of the roller press, and each pressure increasing mode has a different increasing amplitude of the roller pressure of the roller press.

[0039] Further, the control module determines the processing mode of the flatness of the waste not meeting the preset standard according to the surface waviness of the waste, wherein,

[0040] If the surface waviness is less than the preset surface waviness, the magnetic attraction strength of the magnetic attraction conveyor is reduced according to the difference between the preset surface waviness and the surface waviness.

[0041] If the surface waviness is greater than or equal to the preset surface waviness, it is determined that the roll gap pressure of the roller press is uneven, and a pre-warning is issued.

[0042] Further, the surface waviness is the difference between the maximum peak value and the maximum valley value of the flattened waste material surface.

[0043] Compared with the prior art, the beneficial effects of the present application are that the present application identifies the difference in material bending stiffness through bending representation value and adaptively selects the cutting mode of the waste material; selects the magnetic attraction or roller pressure flattening process through the edge deformation representation value of the waste material, eliminates the defects of the wavy edge or curling of the waste material, improves the waste material processing capacity and checks the flattening effect through the thickness standard deviation, thereby improving the waste material processing effect.

[0044] Further, the present application selects the cutting mode according to the bending representation value of the waste material, directly skips the cutting step for low-curvature waste material, only starts the infrared heating band for high-curvature waste material to reduce the material rigidity, avoids heating all waste material, judges through the double parameters of curvature and thickness, solves the limitation of traditional equipment only considering thin plates, and thereby improves the cutting adaptability.

[0045] Further, the present application selects the flattening mode according to the edge deformation representation value; only magnetically attracts the light deformation waste material, rolls the medium-high deformation waste material through the roller press, and flattens the heavy deformation waste material through the roller press first and then magnetically attracts it, and thereby improves the flattening efficiency.

[0046] Further, the present application checks the flattening effect of the waste material through the thickness standard deviation, quantifies the flattening effect of the waste material, eliminates subjective misjudgment, introduces the interlayer gap uniformity representation value as a secondary determination parameter, improves the detection accuracy, analyzes and locates the defect causes through the surface waviness, determines the defect through the thickness standard deviation classification judgment, the secondary verification of the interlayer uniformity, and the surface waviness, and thereby forms a three-order quality control system to realize real-time detection and intelligent adjustment.

[0047] Further, the present application uses the interlayer gap uniformity representation value as an evaluation index of the stacking state of the waste material, breaks through the limitations of traditional manual visual inspection or single-point distance measurement, and thereby improves the detection accuracy.

[0048] Further, the present application sets a plurality of pressure increasing modes for the increase of the roller pressure of the roller press, and each pressure increasing mode has a different increase amplitude of the roller pressure of the roller press, and thereby realizes the precise control of the increase amplitude of the roller pressure.

[0049] Further, the present application determines the processing mode of the waste material flatness effect not meeting the standard through the surface waviness of the waste material, when the surface waviness is less than the preset threshold value, it reflects that there is local small fluctuation in the waste material, because the magnetic attraction force is too strong, the waste material is excessively stretched, therefore the magnetic attraction strength of the magnetic attraction conveyor belt is reduced; when the surface waviness exceeds the threshold value, it shows that there is systematic deformation in the waste material, due to uneven roller gap pressure, the waste material produces buckling instability phenomenon, thereby realizing the accurate positioning of the defect processing mode.

[0058] The embodiment of the application provides a stamping waste automatic collection system of an intelligent steel drum production line, which comprises:

[0059] The waste cutting assembly comprises an infrared heating belt for heating the waste and a shearing machine arranged at the output end of the infrared heating belt for shearing the waste;

[0060] The waste flattening assembly is arranged at the output end of the waste cutting assembly and is used for flattening the waste after cutting, and comprises, in sequence along the flow direction of the waste, a magnetic attraction conveyor belt connected with the output end of the shearing machine and a roller presser arranged at the upper part of the magnetic attraction conveyor belt;

[0061] The waste collection assembly is arranged at the output end of the waste flattening assembly and comprises a collection rack for collecting the waste after flattening;

[0062] The data acquisition module comprises a curvature acquisition unit for acquiring the curvature of the waste, a thickness acquisition unit for acquiring the thickness of the waste, a distance acquisition unit for acquiring the vertical distance between the highest point of the edge of the waste and the plane of the magnetic attraction conveyor belt, a distance acquisition unit for acquiring the interlayer gap distance of the waste, and a fluctuation acquisition unit for acquiring the peak and valley value of the surface of the waste;

[0063] The mode determination module is connected with the waste cutting assembly, the waste flattening assembly and the data acquisition module respectively, and is used for calculating the bending representation value of the waste according to the curvature of the waste and the thickness of the waste to determine the cutting mode of the waste, and determining the edge deformation representation value of the waste according to the vertical distance between the highest point of the edge of the waste and the plane of the magnetic attraction conveyor belt to determine the flattening mode of the waste after cutting;

[0064] The control module is connected with the waste cutting assembly, the waste flattening assembly, the data acquisition module and the mode determination module respectively, and is used for judging whether the flattening of the waste conforms to the preset standard according to the thickness standard deviation value under the condition that the flattening of the waste does not conform to the preset standard, or determining the processing mode of the flattening of the waste that does not conform to the preset standard according to the surface wave degree of the waste.

[0065] Specifically, the specific structure of the mode determining module and the control module is not limited, and the mode determining module and the control module can be composed of a logic component including a field programmable component, a computer or a microprocessor in the computer.

[0066] In this embodiment, the curvature acquisition unit is a line laser scanner; the thickness acquisition unit is a laser thickness gauge; the distance acquisition unit is a capacitive displacement sensor; the distance acquisition unit is an ultrasonic sensor; and the fluctuation acquisition unit is a laser profiler.

[0067] Specifically, the mode determining module determines the cutting mode of the waste material according to the bending characteristic value of the waste material, wherein,

[0068] If the bending characteristic value is less than a first preset bending characteristic value 0.2, the first cutting mode is determined to be used;

[0069] If the bending characteristic value is greater than or equal to the first preset bending characteristic value and less than a second preset bending characteristic value 0.4, the second cutting mode is determined to be used;

[0070] If the bending characteristic value is greater than or equal to the second preset bending characteristic value, the third cutting mode is determined to be used;

[0071] The bending characteristic value of the waste material is determined by the curvature of the waste material and the thickness of the waste material, and reflects the local bending stress concentration degree of the waste material.

[0072] When the bending characteristic value is less than the first preset bending characteristic value 0.2, the bending stress of the waste material does not exceed the material yield strength, and shear at room temperature will not produce obvious cracks or burrs;

[0073] When the bending characteristic value is greater than or equal to the second preset bending characteristic value 0.4, the bending stress of the waste material has approached the material shear strength, and direct cutting may cause blade wear or waste tearing, which needs to be softened by heating to reduce the shear resistance.

[0074] In this embodiment, the bending characteristic value of the waste material is the product of the curvature of the waste material and the thickness of the waste material. It can be understood that the unit of curvature is m -1 , the unit of thickness is m, and the unit of the product of the two is 1, i.e. dimensionless, so the bending characteristic value itself has no unit.

[0075] In this embodiment, the first preset bending characteristic value is in the range of (0.1, 0.3), and the second preset bending characteristic value is in the range of (0.35, 0.55). Preferably, the first preset bending characteristic value is selected as 0.2, and the second preset bending characteristic value is selected as 0.4.

[0076] Specifically, the mode determining module is provided with three cutting modes including:

[0077] The first cutting mode is not cutting the waste material;

[0078] The second cutting mode is controlling the shearing machine to cut the waste material;

[0079] The third cutting mode is controlling the shearing machine to cut the waste material after softening the waste material by starting the infrared heating belt.

[0080] Specifically, the mode determination module determines a flattening mode of the waste material after cutting according to the edge deformation representation value of the waste material, wherein,

[0081] If the edge deformation representation value is less than a first preset edge deformation representation value 0.075, at this time the edge of the waste material is slightly warped, the magnetic suction conveyor is controlled to perform edge flattening;

[0082] If the edge deformation representation value is greater than or equal to the first preset edge deformation representation value and less than a second preset edge deformation representation value 0.175, the roller press is controlled to perform edge flattening;

[0083] If the edge deformation representation value is greater than or equal to the second preset edge deformation representation value, the roller press is controlled to perform edge flattening and then the magnetic suction conveyor is controlled to perform edge flattening;

[0084] The edge deformation representation value is a ratio between a vertical distance between a highest point of the edge of the waste material and a plane of the magnetic suction conveyor and a preset vertical distance 1.5 mm.

[0085] In this embodiment, the first preset edge deformation representation value is in a range of (0.05, 0.10) and the second preset edge deformation representation value is in a range of (0.15, 0.20), preferably, the first preset edge deformation representation value is 0.075 and the second preset edge deformation representation value is 0.175.

[0086] Specifically, the control module determines whether the flattening of the waste material conforms to a preset standard according to a thickness standard deviation value of the waste material on the collection rack, wherein,

[0087] If the thickness standard deviation value is less than a first preset thickness standard deviation value 0.05 mm, it is determined that the flattening of the waste material conforms to the preset standard;

[0088] If the thickness standard deviation value is greater than or equal to the first preset thickness standard deviation value and less than a second preset thickness standard deviation value 0.10 mm, it is determined that the flattening of the waste material does not conform to the preset standard, and whether the flattening of the waste material conforms to the preset standard is determined again according to a layer gap uniformity representation value of the waste material;

[0089] if the thickness standard deviation value is greater than or equal to a second preset thickness standard deviation value, it is determined that the flatness of the waste material does not meet the preset standard, and a processing mode of the waste material whose flatness does not meet the preset standard is determined according to the surface waviness of the waste material;

[0090] The thickness standard deviation value is the standard deviation of the thickness of the waste materials on the collection rack, wherein the thickness of the waste materials is obtained by a laser thickness gauge.

[0091] In this embodiment, the first preset thickness standard deviation value is selected to be 0.05 mm, and the second preset thickness standard deviation value is selected to be 0.10 mm.

[0092] Specifically, the control module determines whether the flatness of the waste material meets the preset standard according to the interlayer gap uniformity representation value of the waste materials on the collection rack.

[0093] If the interlayer gap uniformity representation value is less than a preset interlayer gap uniformity representation value 0.3 mm, it is determined that the flatness of the waste material meets the preset standard.

[0094] If the interlayer gap uniformity representation value is greater than or equal to the preset interlayer gap uniformity representation value, it is determined that the flatness of the waste material does not meet the preset standard, and the roller pressure of the roller press is increased according to the difference between the interlayer gap uniformity representation value and the preset interlayer gap uniformity representation value.

[0095] Specifically, the interlayer gap uniformity representation value is the standard deviation of the interlayer gap distance of each waste material.

[0096] In this embodiment, the preset interlayer gap uniformity representation value is selected to be 0.3 mm, which is obtained by taking the arithmetic mean of the standard deviation of the interlayer gap distance of the stacked flat waste material several times, but the above value is not limited thereto, and those skilled in the art can adjust the value according to actual needs.

[0097] Specifically, the control module sets several pressure increasing modes for the increase of the roller pressure of the roller press, wherein,

[0098] If the interlayer gap uniformity representation difference value is less than a first preset interlayer gap uniformity representation difference value 0.15 mm, the roller pressure of the roller press is increased to a corresponding value by using a first pressure adjustment coefficient 1.02.

[0099] If the interlayer gap uniformity difference value is greater than or equal to the first preset interlayer gap uniformity difference value and less than the second preset interlayer gap uniformity difference value 0.25 mm, the second pressure adjustment coefficient 1.04 is used to increase the roll pressure of the roll press to a corresponding value;

[0100] If the interlayer gap uniformity difference value is greater than or equal to the second preset interlayer gap uniformity difference value, the third pressure adjustment coefficient 1.06 is used to increase the roll pressure of the roll press to a corresponding value.

[0101] The interlayer gap uniformity difference value is the difference between the interlayer gap uniformity value and the preset interlayer gap uniformity value.

[0102] Specifically, the control module determines the processing mode of the waste material that does not meet the preset standard according to the surface waviness of the waste material, wherein,

[0103] If the surface waviness is less than the preset surface waviness 0.35 mm, the magnetic attraction strength of the magnetic attraction conveyor is reduced according to the difference between the preset surface waviness and the surface waviness.

[0104] If the surface waviness is greater than or equal to the preset surface waviness, it is determined that the roll gap pressure of the roll press is uneven and a warning is issued.

[0105] Specifically, the surface waviness is the difference between the maximum peak value and the maximum valley value of the flattened waste material surface, reflecting the macroscopic fluctuation degree of the waste material surface, and the peak value and the valley value of the flattened waste material surface are obtained by a fluctuation acquisition unit.

[0106] Specifically, the value of the preset surface waviness can be adjusted by a person skilled in the art according to the demand for detection and evaluation accuracy of the quality of the waste material surface. The higher the demand for detection and evaluation accuracy, the smaller the value of the preset surface waviness, and preferably, the value of the preset surface waviness is in the range of (0.1 mm, 0.5 mm).

If the uniformity value of interlayer gap is less than the preset uniformity value of interlayer gap, then the flatness of the waste material is determined to meet the preset standard. If the uniformity of interlayer gap is greater than or equal to the preset uniformity of interlayer gap, it is determined that the flatness of the waste does not meet the preset standard, and the rolling pressure of the roller press is increased according to the difference between the uniformity of interlayer gap and the preset uniformity of interlayer gap.

7. The automatic collection system for stamping waste in the intelligent steel drum production line according to claim 6, characterized in that, The uniformity of the interlayer gap is characterized by the standard deviation of the interlayer gap distance of each waste material.

8. The automatic collection system for stamping waste in the intelligent steel drum production line according to claim 7, characterized in that, The control module has several pressure increase methods for increasing the rolling pressure of the roller press, and each pressure increase method increases the rolling pressure of the roller press by a different amount.

9. The automatic collection system for stamping waste in the intelligent steel drum production line according to claim 8, characterized in that, The control module determines the processing method for waste whose flatness does not meet the preset standard based on the surface waviness of the waste. If the surface waviness is less than the preset surface waviness, the magnetic attraction strength of the magnetic conveyor belt is reduced according to the difference between the preset surface waviness and the surface waviness. If the surface waviness is greater than or equal to the preset surface waviness, then the uneven roller gap pressure of the roller press is determined and an early warning is issued.

10. The automatic collection system for stamping waste in the intelligent steel drum production line according to claim 9, characterized in that, The surface waviness is the difference between the maximum peak value and the maximum trough value of the flattened waste surface.
