Description

Technical Field

[0001] The invention relates to the technical field of thermal straightening devices, and in particular to a short-process flexible and efficient micron-level precision alloy foil thermal straightening device. Background Art

[0002] Precision alloy foil and other metal foils are prepared by cold rolling, calendering and rewinding. Since the thickness of precision alloy micron-level foil is 0.01mm, 0.02mm, 0.03mm, etc., the cold-hardened micron-level foil needs to be subjected to hot drawing and straightening treatment. The purpose is to remove the residual stress in the internal structure of the foil and the dislocation defects in the grain arrangement caused by cold rolling through hot drawing and straightening, so that the foil plate has excellent flatness and consistency.

[0003] At present, the traditional hot stretching process for preparing precision alloy foil and other metal foil has a very long production line length, and the foil prepared by the traditional hot stretching method is thin in specifications and has a large range, which increases the difficulty and risk of preparation, reduces production efficiency, and causes a large amount of production energy consumption and increased production costs. Secondly, when the uncoiler in the straightening device is loading, especially when installing foil with a small installation aperture, since the foil material is relatively thin, it is easily scratched by the front end of the top clamping plate when installed on the outside of the four top clamping plates on the uncoiler, which causes the inner wall of the foil to be easily worn, affecting the subsequent preparation quality. Therefore, the present application provides a short-process, flexible and efficient micron-level precision alloy foil hot straightening device to meet the needs. Summary of the invention

[0044] like Figures 2 to 11As shown, in order to guide the feeding of the metal foil strip coil with a small mounting hole, a guiding mechanism 30 is provided, including a mounting frame 31 fixedly connected to the outer side of the top tightening plate 101 by four first bolts 32, and the vertical cross-sections at both ends of the mounting frame 31 are both n-shaped structures, and a guide plate 35 is integrally formed in the groove provided at the front end of the mounting frame 31 through a connecting plate 33, and a first weakening groove 34 is provided at the bending connection between the guide plate 35 and the connecting plate 33, and a plurality of equally spaced buckling grooves 351 are provided at the bottom end of the guide plate 35, and two symmetrically distributed second arcuate inclined surfaces 352 are provided in the plurality of buckling grooves 351, and the top of the arcuate lap plate 104 is provided with a first arcuate inclined surface 105 adapted to the second arcuate inclined surface 352, and the guide plate 35 A plurality of equidistantly arranged rubber protrusions 36 are fixed to the top, and two symmetrically distributed mounting base plates 37 are fixed to the top of the mounting frame 31 near its rear end. The two mounting base plates 37 are respectively fixed to the top of the mounting frame 31 by two second bolts, and the ends of the two mounting base plates 37 that are close to each other are integrally formed with a clamping plate 372 through a second weakened groove 371.

Card grooves 375 adapted to the block 374 are provided on both side walls of the guide plate 35.

[0045] Among them, the setting of the horizontal avoidance portion 373 makes it possible to facilitate the guide plate 35 to be deformed and fit onto the mounting frame 31 through the first weakened groove 34, so that the two clamping plates 372 can be stretched open, so that the clamping plates 372 can be deformed through the second weakened groove 371 and opened until the block 374 can be inserted into the corresponding slot 375, thereby effectively preventing the metal foil strip coil from breaking due to the rebound force of the guide plate 35 when it is unloaded to the last section.

[0046] like Figures 2 to 11As shown, in order to achieve the rebound reset of the four guide plates 35 by means of the retraction effect of the four tightening plates 101, a steel wire 381 is fixedly connected to the middle of the side walls of the two clamping plates 372 that are opposite to each other, and a first limiting sleeve 382 is fixedly connected to the top of the two mounting base plates 37.

A third weakening groove 391 is opened in the middle of the bottom arc surface of the arc-shaped bending plate 39, and multiple wire threading grooves 38 are connected through the opened wire threading holes.

[0047] Among them, when the four tightening plates 101 are close to each other, the outer ends of the four arc-shaped bending plates 39 are in contact and pressed against each other, so that the arc-shaped bending plates 39 are deformed through the third weakening groove 391, and the setting of the limit block 384 and multiple second limit sleeves 383 is cooperated, so that the two steel wire ropes 381 pull the clamping plate 372, so that the two clamping plates 372 can be opened respectively through the second weakening groove 371, and the card block 374 is caused to disengage from the card groove 375 respectively, so that the guide plate 35 is reset and tilted under the rebound action of the first weakening groove 34, so as to facilitate the subsequent feeding and guiding of the metal foil strip coil.

[0048] The working principle of the technical solution provided by the present invention is as follows:

[0049] First, the first step: the precision alloy foil strip and other metal foil strip are transported to the welding platform 4 through the guide roller 2 by the unwinding machine 1 for welding and leading;

[0050] Step 2: Then, the precision alloy foil strip and other metal foil strip are transported to the hot stretching furnace 7 through the No. 1 tension roller group 5 and the conveying roller 6 for recrystallization heat treatment or stress relief heat treatment;

[0051] Step 3: Further precision alloy foil strips and other metal foil strips are sent to the cooling box 8 for cooling treatment. After the cooled foil strips are conveyed to the No. 2 tension roller group 11 through the conveyor roller 6, they enter the straightening machine 12 for straightening and flattening;

[0052] Step 4: The precision alloy foil strip and other metal foil strips after tensioning and straightening are conveyed to the winding machine 16 through the 3# tension roller group 13 and the guide roller 2 for winding;

[0053] In summary, the temperature controllability and speed of precision alloy foil during heating can be effectively controlled, and the material loss can be avoided, ensuring the removal of residual stress inside the tissue during the heat treatment of the foil. The device has a short span and the front section hot stretching is flexibly connected to the rear section straightening machine 12 groups, which can better adapt to the flexible regulation of the flatness of foils and strips of different specifications;

[0054] Secondly, when the metal foil strip coil with a small mounting hole is installed on the four top clamping plates 101, the metal foil strip coil is installed by an external lifting device, and the guide plates 35 provided on the four mounting frames 31 can guide the middle mounting hole of the metal foil strip coil to avoid scratches between the metal foil strip coil and the front ends of the four guide plates 35, and then the four top clamping plates 101 are opened by the opening device 102 of the prior art on the uncoiler 1, so that the four guide plates 35 are pressed against the inner wall of the mounting hole of the metal foil strip coil, and When pressed, the inner wall of the mounting hole of the metal foil strip coil can be protected by a plurality of rubber protrusions 36. At the same time, the four guide plates 35 are respectively deformed and fitted to the outer side of the mounting frame 31 through the first weakened grooves 34. The triangular limit frame 103 can be synchronously limited and fixed by a plurality of equally spaced buckling grooves 351 and the arc-shaped lap plate 104, thereby greatly improving the fixing efficiency of the triangular limit frame 103. At the same time, the guide plate 35 opens the two blocks 374 through the two third inclined surfaces set at the bottom, thereby The two clamping plates 372 can be deformed between the second weakened groove 371 and the mounting base 37 respectively, until the clamping block 374 is clamped in the clamping groove 375 opened on the outer wall of the guide plate 35, thereby locking the guide plate 35. The locking setting of the guide plate 35 can prevent the metal foil strip coil from being bounced up by the guide plate 35 and causing the material to collapse when the material is discharged to the last section of the material, thereby greatly improving the stability of the discharge. Moreover, when the metal foil strip coil is discharged, the four top plates 101 are closed by the opening device 102 of the prior art. When the four arc-shaped curved plates 39 are close, and when they are retracted, the front ends of the four arc-shaped curved plates 39 are in contact, so that the four arc-shaped curved plates 39 are deformed through the third weakened groove 391, thereby prompting the two steel wire ropes 381 to pull the clamping plate 372, and the clamping plate 372 is deformed between the second weakened groove 371 and the mounting base plate 37, so that the clamping blocks 374 are disengaged from the clamping grooves 375, and the guide plate 35 will automatically reset and tilt due to the rebound action of the first weakened groove 34, so as to facilitate the subsequent feeding and guiding of the metal foil strip coil, and no manual intervention is required throughout the process.
