Description

Technical Field

[0001] This invention relates to the field of sheet metal processing technology, and in particular to an ultra-thin metal sheet processing production line and processing method. Background Technology

[0002] Chinese Patent CN219052473U, filed by the inventor on October 13, 2022, describes a production line for ultra-fine seamless metal tubes. The line includes a material rack, a feeding mechanism, a positioning mechanism, a pre-pressing mechanism, a second positioning mechanism, a forming mechanism, a third positioning mechanism, and a welding mechanism to produce seamless metal tubes. It uses rolled metal sheets as raw material. The ultra-thin metal sheets have irregular shapes, with the thinnest end being no less than 0.02mm and no more than 0.3mm, and the thickest end being no less than 0.05mm and no more than 0.5mm, preferably 0.02mm-0.2mm. There is a uniform thickness transition between the thickest and thinnest ends. This requires high precision in the processing equipment, and domestic production is not yet possible. While foreign countries can produce these irregularly shaped metal sheets, their production processes are not publicly disclosed, and it is difficult to remove processing debris during processing, which can easily damage machinery.

[0003] Therefore, existing ultra-thin metal sheet processing production lines still need improvement. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the purpose of this invention is to provide an ultra-thin sheet processing production line that can be used to process the metal sheets described in the background art with high precision.

[0005] The technical solution adopted by this invention to solve the problem is: an ultra-thin sheet processing production line, the production line including a first material rack, a first reversing mechanism, a positioning mechanism, a processing mechanism, a first pulling mechanism, a second reversing mechanism, a second pulling mechanism, and a second material rack. The first material rack is used to output flat metal sheets. The first reversing mechanism is used to receive the metal sheets output from the first material rack and twist the metal sheets to a vertical direction. The positioning mechanism is used to receive the metal sheets output from the first reversing mechanism and position the metal sheets. The processing mechanism includes a vertically arranged mold. ，The mold has a through groove extending in the left-right direction. The through groove is used to receive and position the metal sheet output from the positioning mechanism. The mold has a U-shaped groove with a processing window near the through groove. The processing window communicates with the through groove. The processing mechanism also includes a tool driving mechanism and a tool. The tool is located in the U-shaped groove and part of the tool is located in the processing window. The tool is used to process the metal sheet in the processing window. The first pulling mechanism is used to receive the metal sheet output from the processing mechanism and pull the metal sheet to the right. The second reversing mechanism is used to receive the metal sheet output from the pulling mechanism and twist the metal sheet to the horizontal direction. The second pulling mechanism is used to receive the metal sheet output from the second reversing mechanism and pull the metal sheet to the right. The second rack is used to store the metal sheet output from the second pulling mechanism.

[0006] As a further improvement to the above technical solution, both the first and second reversing mechanisms include a main reversing mechanism and a secondary reversing mechanism. The main reversing mechanism includes a pair of horizontal roller groups arranged vertically, and the secondary reversing mechanism includes a pair of inclined roller groups arranged at an angle. The first reversing mechanism also includes a pair of vertically arranged vertical roller groups arranged front to back, with a certain distance between the two rows of vertical roller groups. The vertical roller groups are used to vertically convey the metal sheet. Through the first reversing mechanism, the metal sheet can be rotated from the horizontal direction to the vertical direction, and through the second reversing mechanism, the metal sheet can be rotated from the vertical direction to the horizontal direction.

[0007] As a further improvement to the above technical solution, a leveling mechanism and a detection mechanism are also included. The leveling mechanism is disposed between the positioning mechanism and the mold. The leveling mechanism is used to receive the metal sheet output from the positioning mechanism and level the metal sheet. The detection mechanism is disposed between the mold and the first feeding mechanism. The leveling mechanism is used to level the sheet, and the detection mechanism is used to detect the processing depth of the metal sheet.

[0008] As a further improvement to the above technical solution, a laser texturing mechanism is also included. The laser texturing mechanism is disposed between the second reversing mechanism and the second material rack. The laser texturing mechanism is used to receive the metal sheet output from the second reversing mechanism and perform laser texturing on the metal sheet.

[0009] As a further improvement to the above technical solution, a control center is also included, and the processing mechanism, the first material pulling mechanism, the second material pulling mechanism and the laser texturing mechanism are all electrically connected to the control center.

[0010] As a further improvement to the above technical solution, the mold includes a pressure plate, a base plate and a mold base arranged sequentially from front to back, and also includes an adjustment mechanism for driving the pressure plate closer to the base plate. The through groove is provided on the front side wall of the base plate, the U-shaped groove and the processing window are provided on the pressure plate, and the cutting tool is arranged in a vertical spindle shape or gourd shape. The pressure plate is used to press the metal sheet to prevent the metal sheet from shaking.

[0011] As a further improvement to the above technical solution, a blind hole is provided on the base plate. The blind hole is located on the side of the through groove away from the cutting tool. A vent hole is provided on the blind hole and communicates with the through groove. It also includes a negative pressure device. The suction port of the negative pressure device is located at the opening of the blind hole. When the negative pressure device is activated, it evacuates the blind hole and sucks the metal sheet through the vent hole to prevent the metal sheet from shifting during processing.

[0012] As a further improvement to the above technical solution, the adjustment mechanism includes a fixed plate, a movable plate, and a handwheel. The fixed plate, movable plate, and pressure plate are arranged sequentially from front to back. A threaded adjusting column is fixedly connected to the handwheel. A nut is provided in the fixed plate. The threaded adjusting column is throttlely connected to the nut. The threaded adjusting column is rotatably connected to the movable plate. A spring is provided between the movable plate and the pressure plate. The pressure plate includes a first pressure plate, a second pressure plate, and a third pressure plate. The rear sidewalls of the first pressure plate, the second pressure plate, and the third pressure plate are arranged sequentially from top to bottom. The first pressure plate, the second pressure plate, and the third pressure plate are all slidably engaged with the threaded adjusting column. Springs are provided on the front side of the first pressure plate, the front side of the second pressure plate, and the front side of the third pressure plate.

[0013] As a further improvement to the above technical solution, the positioning mechanism includes a rear positioning plate and a front positioning plate disposed in front of the rear positioning plate. There is a certain gap between the rear positioning plate and the front positioning plate. A sliding groove is formed between the rear positioning plate and the front positioning plate. The sliding groove is located on the upper part of the rear positioning plate. The mechanism also includes an upward pushing block disposed in the sliding groove. An adjusting screw is provided on the top of the rear positioning plate. A nut is provided on the top of the upward pushing block. The adjusting screw is connected to the nut. A spring is also provided at the connection between the adjusting screw and the upward pushing block. Multiple positioning rollers are provided at the lower part of the upward pushing block and the lower part of the rear positioning plate, arranged in the front-back direction. The distance between the upper and lower positioning rollers is adjusted by adjusting the adjusting screw to control the upward and downward sliding of the upward pushing block.

[0014] As a further improvement to the above technical solution, S1, the first material rack unloads the metal sheet; S2, the first reversing mechanism changes the metal sheet from a horizontal to a vertical orientation; S3, the positioning mechanism positions the metal sheet; S4, the leveling mechanism levels the front and rear sides of the metal sheet; S5, the mold limits and compresses the metal sheet; S6, the cutting tool cuts on the metal sheet to form a groove area; S7, the detection mechanism detects the depth of the groove area; S8, the first pulling mechanism pulls the metal sheet to the right; S9, the second reversing mechanism twists the metal sheet from a vertical to a horizontal orientation; S10, the laser texturing mechanism performs laser texturing on the metal sheet; S11, the second pulling mechanism pulls the metal sheet to the right; S12, the second material rack winds the metal sheet into a roll shape.

[0015] The beneficial effects of the present invention are: the sheet passes through the through groove, a processing window is provided at the through groove, and the cutting tool is located at the processing window. Due to the limitation of the processing window, it is easy to detect the installation accuracy of the cutting tool and control the distance between the cutting tool and the sheet being processed when installing the cutting tool.

[0016] Meanwhile, due to the window's restriction and the mold's pressure on the metal sheet, the deviation of the sheet caused by the inability to fix the ultra-thin metal sheet during processing and the vibration during processing are effectively controlled, thereby improving the processing accuracy and yield, and achieving precise cutting of the metal sheet.

[0017] Furthermore, the vertically arranged metal sheets allow the processed metal scraps to fall downwards, facilitating their removal.

[0018] The metal sheet of the present invention can also be sheet-shaped but stored in rolls. Attached Figure Description

[0074] Usage effect:

[0075] Metal sheet 11 is output from the first feeder 1 to the main reversing mechanism 21. Metal sheet 11 passes horizontally through the main reversing mechanism 21 and is output to the right. When metal sheet 11 passes through the secondary reversing mechanism 22, it is twisted to tilt forward at a 45-degree angle. When metal sheet 11 passes through the vertical roller group 23C, it is twisted to the vertical direction.

[0076] The upper and lower edges of the metal sheet 11 are slidably connected to the positioning roller 32 to prevent the metal sheet 11 from deviating. Then the metal sheet 11 passes through the leveling mechanism 9. The front and back sides of the metal sheet 11 are slidably connected to the leveling roller 92 to prevent the metal sheet 11 from being uneven.

[0077] When the metal sheet 11 slides to the right into the through groove 42, it is limited and squeezed by the pressure plate 412. The pressure plate 412 can prevent the metal sheet 11 from coming out of the through groove 42 and prevent the metal sheet 11 from vibrating.

[0078] After the negative pressure device 12 is started, the air in the blind hole 414 is evacuated, creating a negative pressure in the blind hole 414. The metal sheet 11 will be adsorbed at the vent hole 415, and the tool 45 will extend into the U-shaped groove 43. The tool 45 will pass through the processing window 44 and process the metal sheet 11.

[0079] The metal sheet 11 is then pulled to the right by the first pulling mechanism 5 to the groove 104, and the micrometer 103's detection head will perform depth detection on the groove area 111;

[0080] When the metal sheet 11 is output to the right to the auxiliary reversing mechanism 22 on the second reversing mechanism 2A, it is twisted from the vertical direction to tilted forward at 45 degrees. Then the metal sheet 11 is output to the main reversing mechanism 21 and twisted to the horizontal direction.

[0081] The metal sheet 11 is then pulled to the right by the second pulling mechanism 7 to the positioning groove 135, and the laser head of the laser texturing machine 131 will perform laser texturing on the metal sheet 11.

[0082] Finally, the metal sheet 11 will be output to the second feeder 8 and wound up on the second feeder 8.
