Description

Technical Field

[0001] This utility model relates to the field of aluminum sheet and strip cutting technology, and more specifically, to an aluminum strip cutting device. Background Technology

[0002] Currently, aluminum sheet and strip refer to aluminum sheets or strips made primarily from aluminum and mixed with other alloying elements. Aluminum sheet and strip are important basic materials for my country's national economic development and are widely used in industries such as aviation, aerospace, construction, printing, transportation, electronics, chemicals, food, and pharmaceuticals.

[0003] A search revealed that application number CN202320813176.3, entitled "A Cutting Device for Aluminum Sheets and Strips," relates to a Chinese utility model patent (publication number CN206474742U) that discloses an automatic cutting machine for thin aluminum sheets. While the cutting process eliminates the need for manual intervention, directly cutting the aluminum sheet, this device can only cut sheet-like aluminum sheets and cannot cut coiled aluminum strips. Furthermore, the cutting length requires manual control, leading to reduced efficiency in mechanized production. The solution addresses this by having a cutting motor rotate, simultaneously driving a connected rod to rotate, thus enabling the connected rod to... The pull rod moves, and the connecting rod is correspondingly set with the pull rod, so that the pull rod pulls the cutting blade to slide in the groove inside the crossbeam, which can perform reciprocating motion, thereby making the cutting blade cut the aluminum strip. The design of this utility model realizes the fixed length cutting of aluminum strip by controlling the timed operation of the cutting motor, thus realizing the automated production of aluminum strip and speeding up work efficiency. However, this application requires the aluminum strip to be in a stationary state when cutting the aluminum strip, which affects the continuity of production and work efficiency. At the same time, the traditional flying shear structure is relatively complex, has high cost, and has limited limiting effect on the aluminum strip, affecting the stability of cutting. Further improvements can be made.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0029] According to an embodiment of the present invention, an aluminum strip cutting device is provided.

[0030] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figure 1-4As shown, an aluminum strip cutting device according to an embodiment of the present invention includes a workbench 1 and a support platform 2. The support platform 2 is fixedly installed inside the workbench 1, and conveying rollers 6 are rotatably connected to both sides of the support platform 2 inside the workbench 1. The top surface of the workbench 1 is flush with the top surface of the conveying rollers 6, and an end plate 12 is fixedly installed on the top surface of the support platform 2. A first gantry 3 is slidably connected between the end plates 12 on the top surface of the support platform 2, and a hydraulic rod 4 is fixedly installed on the top surface of the first gantry 3. A cutter 5 is fixedly installed on the bottom surface of the piston rod of the hydraulic rod 4. A guide rod 14 is fixedly installed between the plates 12, and the guide rod 14 passes through the first gantry 3 and is slidably connected to the first gantry 3. A spring 13 is sleeved on the outside of the guide rod 14 between the end plate 12 and the first gantry 3. A second gantry 7 and a third gantry 15 are fixedly mounted on both sides of the support platform 2 on the top surface of the workbench 1. A first electric cylinder 9 and a second electric cylinder 16 are fixedly installed on the top surface of the second gantry 7 and the third gantry 15, respectively. A first pressure roller 11 and a second pressure roller 16 are fixedly installed on the bottom surface of the moving rod of the first electric cylinder 9 and the second electric cylinder 16, respectively. A pressure roller 17 and a third electric cylinder 18 are fixedly mounted on the surface of the second gantry 7. A roller frame 19 is fixedly mounted on the other end of the moving rod of the third electric cylinder 18, and a side roller 8 is rotatably connected to the inner side of the roller frame 19. When cutting the aluminum strip, the aluminum strip is unwound by the unwinding machine onto the top surface of the conveyor roller 6. As the conveyor roller 6 enters below the first gantry 3, a laser meter counter 10 located on the inner top surface of the second gantry 7 counts the length. When the set cutting length is reached, the hydraulic rod 4 is activated, pushing the cutter 5 downwards. The cutter 5 then applies pressure to the aluminum strip. When the cutting blade 5 inserts into the upper surface of the aluminum strip, it moves to the right under the pushing force of the aluminum strip, causing the first gantry 3 to move along with the aluminum strip. The spring 13 is compressed until the cutting blade 5 cuts the aluminum strip and rises. Then, the spring 13 pushes the first gantry 3 back to its original position, allowing for the next cutting operation. The cutting blade 5 of this device can move along with the aluminum strip, avoiding the problem of interrupting the aluminum strip conveying, facilitating continuous cutting work, and improving work efficiency. Compared with traditional flying shear equipment, the structure is simpler and easier to use.

[0031] In one embodiment, a laser meter counter 10 is fixedly installed on the inner top surface of one end of the second gantry 7, and the output end of the laser meter counter 10 is electrically connected to the input end of the hydraulic rod 4. This is a common meter counting control structure, which will not be described in detail here.

[0032] In one embodiment, the end plate 12 is arranged in two sets, the guide rod 14 and the spring 13 are each arranged in two sets, and the bottom surface of the first gantry 3 is provided with a guide hole that cooperates with the guide rod 14.

[0033] In one embodiment, the side rollers 8 are located between the conveying rollers 6, and the bottom installation height of the side rollers 8 is lower than the top installation height of the conveying rollers 6. There are two sets of side rollers 8 arranged symmetrically, and the side rollers 8 are rotatably connected to the roller frame 19 through roller shafts. When cutting aluminum strip, the first pressure roller 11 and the second pressure roller 17 press the aluminum strip under the drive of the second electric cylinder 16 of the first electric cylinder 9 to prevent the aluminum strip from moving up and down. At the same time, the side rollers 8 roll against the side of the aluminum strip to prevent the aluminum strip from moving back and forth, stabilize the conveying of the aluminum strip, prevent the aluminum strip from deviating during cutting, and improve the stability and working efficiency of the cutter.

[0034] In one embodiment, the two ends of the spring 13 are fixedly connected to one side surface of the first gantry 3 and the end plate 12, respectively, to prevent the spring 13 from detaching from the first gantry 3 or the end plate 12.

[0035] In one embodiment, a drive device is fixedly installed on the back face of the workbench 1, and the output end of the drive device is fixedly connected to one end of the roller shaft of the conveying roller 6, which is a common drive structure.

[0036] In one embodiment, the side roller 8 and the first pressure roller 11 are staggered to avoid mutual interference.

[0037] Working principle:

[0038] When cutting aluminum strip, the strip is unwound by the unwinding machine onto the top surface of the conveyor roller 6. As the conveyor roller 6 enters below the first gantry 3, the laser meter counter 10 located on the top surface of the second gantry 7 measures the length. When the set cutting length is reached, the hydraulic rod 4 is activated, pushing the cutter 5 downwards. The cutter 5 cuts the aluminum strip under pressure. When the blade of the cutter 5 inserts into the upper surface of the aluminum strip, the cutter 5 is pushed to the right by the aluminum strip, causing the first gantry 3 to move along with the aluminum strip. The spring 13 is compressed until the cutter 5 cuts the aluminum strip and rises. Then, the spring 13 pushes the first gantry 3 back to its original position, allowing the cutting process to continue. During the next cut, the cutter 5 of this device can move along with the aluminum strip, avoiding the problem of the aluminum strip conveying stopping, facilitating continuous cutting work, and improving work efficiency. Compared with traditional flying shear equipment, the structure is simpler and easier to use. At the same time, when cutting the aluminum strip, the first pressure roller 11 and the second pressure roller 17 press the aluminum strip under the drive of the second electric cylinder 16 of the first electric cylinder 9, respectively, to prevent the aluminum strip from moving up and down. Meanwhile, the side roller 8 rolls and abuts against the side of the aluminum strip to prevent the aluminum strip from moving back and forth, stabilizing the conveying of the aluminum strip, preventing the aluminum strip from deviating during cutting, and improving the stability and work efficiency of the cutter.
