Description

Technical Field

[0001] The invention relates to the technical field of metal plate and strip shearing, in particular to a fully automatic circular shear for finishing metal plate and strip. Background Art

[0002] After metal plastic processing, a series of operations are performed to meet the user's final requirements for surface quality, size, shape, and certain performance. These operations primarily include flame cleaning, cooling after hot working, coiling, cutting, straightening, physical inspection and grinding for defects, marking, and packaging. Currently, technicians typically use circular shears to cut metal strips.

[0003] Disc shears, also known as disc shears, usually use rotating disc blades to continuously and longitudinally shear moving plates and strips, sometimes cutting plates and strips into narrower strips or trimming their edges.

[0004] When the existing fully automatic circular shear is in use, when the thickness of the metal strip is higher than the length of the cutting blade, using the cutting blade to cut the metal strip will cause damage to the cutting blade and the metal strip. When the thickness of the metal strip is lower than the length of the cutting blade, different materials of the metal strip can withstand different cutting thicknesses. For example, when it is necessary to process aluminum plates and steel plates, the thickness of the aluminum plate is 10mm and the thickness of the steel plate is 5mm. When the aluminum plate can withstand a cutting thickness of 10mm, the steel plate can only withstand a cutting thickness of 5mm. At this time, even if the length of the cutting blade reaches 12mm, it can only cut the aluminum plate, and cannot cut the steel plate by the cutting blade. It needs to be cut by The longitudinal shearing force of the shearing disk is used to shear the 5mm steel plate. If the cutting blade is still used to cut the 5mm steel plate, both the cutting blade and the 5mm steel plate will be damaged, thereby reducing the corresponding processing quality. At the same time, when the existing fully automatic circular shear is in use, when the metal strip to be processed is thin, the longitudinal continuous shearing is used to shear the metal strip, which consumes a lot of processing time and has low processing efficiency. At the same time, since the metal strip is thin, the longitudinal shearing will cause the metal strip to undergo certain deformation, thereby reducing the corresponding shearing quality. Therefore, it is very necessary to design a fully automatic circular shear for metal strip finishing that improves processing efficiency and quality. Summary of the Invention

Several groups of cutting frames are provided on the outside of the transmission plate, and the ends of several groups of cutting frames are connected to shear disks by bearings, and the outer surfaces of several groups of shear disks are installed with cutting blades. During use of the disc shear, the booster cylinder is used to drive the support connecting rod to move, thereby driving the transmission plate to rotate along the transmission shaft, and then driving the cutting frame to move through the transmission plate, and driving the shear disk to move through the cutting frame, and processing the metal sheet strip through the shear disk and the cutting blade. Specifically, the cutting process of the metal sheet strip is as follows: when the booster cylinder pushes the cutting blade to the top of the transmission connecting rod, the cutting blade cuts the metal sheet strip in the process of the transmission connecting rod driving the metal sheet strip to move.

[0011] According to the above technical solution, the working steps of the fully automatic disc shear are:

[0012] Step A: placing the metal strip to be finished on top of several sets of auxiliary connecting rods and transmission connecting rods, and driving the output motor through the control module to drive the transmission connecting rod to rotate, so that the metal strip on top is transported through the several sets of auxiliary connecting rods;

[0013] Step B: The detection module collects the types of metal sheets in the same batch through the data collection unit, and simultaneously detects the thickness of the metal sheets to be finished through the thickness detection unit, records the thickness of the metal sheet as x, and the length of the cutting edge as y, and transmits the detected data information to the judgment module;

DETAILED DESCRIPTION

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] See also Figure 1-5 The present invention provides a technical solution: a fully automatic circular shear for finishing metal strips, comprising a support frame 1, a transmission mechanism, a cutting mechanism, and a data management module, characterized in that: the transmission mechanism and the cutting mechanism are both installed on the inner side of the support frame 1, the transmission mechanism is used to transport the metal strips, the cutting mechanism is located on the top of the transmission mechanism, the cutting mechanism is used to cut the metal strips transported by the transmission mechanism, and automatically adjust the cutting method for metal strips of different specifications, the data management module is used to detect different data information during the use of the circular shears, analyze the detected data information, and control the transmission mechanism and the cutting mechanism according to the analysis results to cut different metal strips;

[0033] The transmission mechanism includes an output motor 2, which is located on the outside of the support frame 1. The output end of the output motor 2 is connected to a transmission connecting rod 3. Both sides of the transmission connecting rod 3 are connected to the bearings at both ends of the support frame 1. The inner bearings of the support frame 1 are connected to several groups of auxiliary connecting rods 4. Several groups of auxiliary connecting rods 4 are located on both sides of the transmission connecting rod 3. Laser output devices 16 are provided at both ends of the inner side of the support frame 1. When the disc shear is in use, the output motor 2 is used to drive the transmission connecting rod 3 to rotate, pushing the metal strip on the top of the transmission connecting rod 3 to move along the several groups of auxiliary connecting rods 4. The laser output device 16 is used to output light in a parallel direction and detect the thickness of the metal strip by the light moving in the parallel direction;

[0034] The cutting mechanism includes a booster cylinder 5, which is located on the inner side of the support frame 1. The output end of the booster cylinder 5 is connected to the supporting connecting rod 6. A transmission plate 8 is provided on the top of the transmission connecting rod 3. Transmission shafts 7 are provided at both ends of the transmission plate 8. Two groups of transmission shafts 7 are connected to the top bearing of the support frame 1. The end of the support connecting rod 6 is fixed to the end of the transmission shaft 7 on one side. Several groups of cutting frames 9 are provided on the outside of the transmission plate 8. The ends of several groups of cutting frames 9 are connected to shear disks 10 with bearings. The outer surfaces of several groups of shear disks 10 are installed with cutting blades 17. During the use of the disc shear, the booster cylinder 5 is used to drive the supporting connecting rod 6 to move, thereby driving the transmission plate 8 to rotate along the transmission shaft 7, and then driving the cutting frame 9 to move through the transmission plate 8, and driving the shear disk 9 to move through the cutting frame 9. The metal strip is processed by the shear disc 9 and the cutting blade 17. Specifically, the cutting process of the metal strip is as follows: when the boost cylinder 5 pushes the cutting blade 17 to the top of the transmission connecting rod 3, the transmission connecting rod 3 drives the metal strip to move, and the cutting blade 17 cuts the metal strip. When the disc shear cuts the metal strip, if the metal strip to be processed is thin, the longitudinal continuous shearing is used to shear the metal strip. The processing time consumed is long and the processing efficiency is low. At the same time, since the metal strip is thin, the longitudinal shearing will cause the metal strip to deform to a certain extent, thereby reducing the corresponding shearing quality. Therefore, the continuous cutting of the metal strip by the cutting blade can improve the corresponding processing efficiency and reduce the possibility of deformation of the metal strip, thereby improving the corresponding processing quality.

[0035] An air delivery pipeline 11 is installed through the interior of the transmission connecting rod 3, and several groups of transmission cylinders 12 are provided on the outer surface of the air delivery pipeline 11. Flexible bags 13 are provided inside the several groups of transmission cylinders 12. The outer surfaces of the several groups of flexible bags 13 are respectively connected to three groups of top blocks 14. Several groups of top blocks 14 are respectively located on one side of several groups of shear discs 10. An air delivery pump 15 is provided on one side of the support frame 1. The output end of the air delivery pump 15 is connected to a pipe on one side of the air delivery pipeline 11. During the use of the disc shear, the air delivery pump 15 is used to deliver gas to the inside of the air delivery pipeline 11 and input the gas into the several groups of transmission cylinders 12 through the air delivery pipeline 11. Inside, after the gas enters the interior of the transmission cylinder 12, it will enter the interior of the flexible bag 13, and then push the three groups of top blocks 14 to move outward. When the boost cylinder 5 drives the shear disk 9 to move quickly toward the transmission connecting rod 3, the three groups of rotating top blocks 14 will exert a certain supporting force on the metal plate strip. The impact force of the shear disk 8 at this time will exert a vertical force on the metal plate strip, thereby realizing the shearing of the metal plate strip. During the use of the disc shear, when cutting thicker metal plates, there is a certain thickness upper limit for directly cutting the metal plate strip through the cutting blade. When the thickness of the metal plate strip is higher than the length of the cutting blade, the cutting blade cannot cut the metal The plate and strip are cut. At the same time, when the material strength and tensile strength of the metal plate and strip are high, even if the thickness of the metal plate and strip does not exceed the length of the cutting blade, the metal plate and strip are cut by the cutting blade, which will cause certain damage to the metal plate and strip and the disc shear. The metal plate and strip need to be sheared multiple times by the longitudinal shearing force of the shearing disk. The metal plate and strip are cut by the longitudinal shearing force, which reduces the damage caused by the cutting to the metal plate and strip and the disc shear, and improves the shearing quality. At the same time, when the shearing disk is used to shear the metal plate and strip, the top block will move outward to exert a certain supporting force on the metal plate and strip, so that dust will not be generated at the shearing point of the metal plate and strip. At this time, the outward moving top block will cause a gap between the metal strip and the transmission connecting rod, thereby allowing external air to move around the metal strip. The flowing air improves the heat dissipation efficiency of the metal strip, preventing the metal strip from being overheated and causing certain damage to the disc shear. When the metal strip is cut by the cutting blade, the top block will move into the inside of the compression cylinder, and the cutting edge of the metal strip will produce a lot of dust. At this time, since the top block is retracted into the inside of the transmission cylinder, external dust will not enter the inside of the transmission cylinder through the gap between the top block and the transmission cylinder, thereby reducing the damage to the disc shear caused by the dust generated by the cutting;

[0036] The data management module includes a detection module, a judgment module and a control module. The detection module is electrically connected to the judgment module, and the judgment module is electrically connected to the control module. The detection module is used to detect the material composition and thickness of the metal strip during the finishing process of the metal strip, and transmit the detected data information to the judgment module. The judgment module is used to compare and judge the received data information, and transmit the judgment result to the control module. The detection module includes a data collection unit and a thickness detection unit. The data collection unit is used to collect the types of plates of the same batch of metal strips. The thickness detection unit is located inside the laser outputter 16. The thickness detection unit detects the thickness of the metal strip to be processed through the laser outputter 16. The control module is electrically connected to the transmission cylinder 12, the output motor 2 and the booster motor 5. The control module is used to control the transmission cylinder 12, the output motor 2 and the booster motor 5 according to the received data information to finish the metal strip;

[0037] The working steps of the fully automatic disc shear are:

[0038] Step A: Place the metal strip to be finished on top of several groups of auxiliary connecting rods 4 and transmission connecting rods 3, and drive the output motor 2 through the control module to drive the transmission connecting rod 3 to rotate, so that the metal strip on top is transported through several groups of auxiliary connecting rods 4;

[0039] Step B: The detection module collects the types of metal sheets in the same batch through the data collection unit, and simultaneously detects the thickness of the metal sheet to be finished through the thickness detection unit, records the thickness of the metal sheet as x, and the length of the cutting blade 17 as y, and transmits the detected data information to the judgment module;

[0040] Step C: The judgment module compares and judges the received data information and transmits the judgment result to the control module;

[0041] Step D: The control module controls the transmission cylinder 12, the output motor 2, and the boost motor 5 according to the received data information to perform finishing on the metal strip;

[0042] By adopting different cutting methods for different metal strips, when the metal strip has high material strength, high tensile strength and thick thickness, the longitudinal shearing force of the shearing disc can be used to cut the metal strip, which can reduce the damage to the cutting edge and the metal strip and improve the corresponding shearing quality. When the metal strip has low thickness, low material strength and low tensile strength, the cutting edge can be used to directly cut the metal strip, which can improve the corresponding processing efficiency.

[0043] In step C, the specific judgment steps of the judgment module are:

[0044] Step C1: When x≤y, the thickness of the metal strip is less than or equal to the length of the cutting blades 17 installed on the outer surfaces of the plurality of shear discs 10, and subsequent determination is required;

[0045] Step C2: When x>y, the thickness of the metal strip is greater than the length of the cutting blades 17 installed on the outer surfaces of the plurality of shearing discs 10. At this time, the metal strip cannot be directly cut by the plurality of cutting blades 17. Therefore, it is determined that the metal strip needs to be sheared by the shearing discs 10.

[0046] When the thickness of the metal strip is greater than the length of the cutting blade, using the cutting blade to cut the metal strip will cause damage to both the cutting blade and the metal strip. When the thickness of the metal strip is less than the length of the cutting blade, different materials of the metal strip can withstand different cutting thicknesses. For example, when it is necessary to process aluminum plates and steel plates, the thickness of the aluminum plate is 10mm and the thickness of the steel plate is 5mm. When the aluminum plate can withstand a cutting thickness of 10mm, the steel plate can only withstand a cutting thickness of 5mm. At this time, even if the length of the cutting blade reaches 12mm, only the aluminum plate can be cut, and the steel plate cannot be cut by the cutting blade. The 5mm steel plate needs to be cut by the longitudinal shear force of the shear disk. If the cutting blade is still used to cut the 5mm steel plate, both the cutting blade and the 5mm steel plate will be damaged. At this time, cutting the 5mm steel plate by the longitudinal shear force of the shear disk can reduce the damage to the cutting blade and the 5mm steel plate, thereby improving the corresponding processing quality.

[0047] In step C1, the specific judgment process is:

[0048] Determine the minimum cutting thickness z of the material based on the type of metal strip, avoid directly cutting metal strips with excessive strength, and continue to compare x with z;

[0049] When x≤z, it is determined that the metal strip can be cut directly by the cutting blade 17;

[0050] When x>z, it is determined that the metal strip cannot be cut directly by the cutting blade 17 and needs to be sheared by the shearing disk 10 .
