Description

Technical Field

[0001] The present 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 produced by cold rolling, calendering and rewinding. Since the thickness specifications of precision alloy micron-level foil are 0.01mm, 0.02mm, 0.03mm, etc., the cold-hardened micron-level foil needs to be subjected to hot 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 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 its 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 four tightening plates when installed on the outside of 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

[0017] In the above scheme, the hot stretching furnace uses electromagnetic induction heating, which is fast and efficient, significantly reducing heat losses due to conduction and air convection. Due to the simple shape and size of the foil, the induction coils are interchangeable and adaptable, making induction heating easy to achieve uniform heating and permeability of the foil.

[0041] Among them, the uncoiler 1 transports the precision alloy foil strip and other metal foil strips to the welding platform 4 through the guide roller 2 for welding leading. Then, the precision alloy foil strip and other metal foil strips are transported to the hot stretching furnace 7 through the No. 1 tension roller group 5 and the conveyor roller 6 for recrystallization heat treatment or stress relief heat treatment; the precision alloy foil strip and other metal foil strips are further sent to the cooling box 8 for cooling treatment.

The outside of the furnace is wrapped with an induction coil and a suitable spacing is reserved; the cooling box 8, hot stretching furnace 7 and straightening machine 12 belong to the existing technology and the straightening principle is not described here.

[0043] Among them, the purpose of the tension sensor 9 is to monitor the process control of tension application in real time, prevent and ensure the stability of the thin strip straightening process, and prevent excessive stretching and shrinkage caused by tension. The tension sensor 9 is an existing technology and will not be described in detail.

[0044] like Figures 2 to 11As shown, in order to be able to guide the feeding of the metal foil strip coil with a small mounting hole, a guiding mechanism 30 is set, which includes a mounting frame 31 fixed to the outside of the tightening plate 101 by four first bolts 32, and the vertical cross-sections at both ends of the mounting frame 31 are n-shaped structures. A guide plate 35 is integrally formed in the groove opened at the front end of the mounting frame 31 through a connecting plate 33, and a first weakening groove 34 is opened at the bending connection between the guide plate 35 and the connecting plate 33, and a plurality of equally spaced buckling grooves 351 are opened at the bottom end of the guide plate 35, and two symmetrically distributed second arc-shaped inclined surfaces 352 are opened in the plurality of buckling grooves 351, and the top of the arc-shaped lap plate 104 is provided with a first arc-shaped inclined surface 105 adapted to the second arc-shaped inclined surface 352, and the top of the guide plate 35 is fixed There are multiple rubber protrusions 36 arranged at equal intervals. Two symmetrically distributed mounting bases 37 are fixed to the top of the mounting frame 31 near its rear end. The two mounting bases 37 are respectively fixed to the top of the mounting frame 31 by two second bolts. The ends of the two mounting bases 37 that are close to each other are integrally formed with a clamping plate 372 through a second weakened groove 371. The bottom ends of the guide plates 35 are provided with symmetrically distributed third inclined surfaces. The shape of the clamping plates 372 is adapted to the shape of the outer wall of the guide plate 35. The tops of the clamping plates 372 are provided with horizontal avoidance portions 373. The two side walls of the two clamping plates 372 facing each other are fixed with a clamping block 374 with a right-angled triangle structure in vertical cross-section. The two side walls of the guide plate 35 are provided with a clamping groove 375 adapted to the clamping block 374.

[0045] Among them, the setting of the horizontal avoidance portion 373 makes it possible to facilitate the guide plate 35 to be deformed and fitted onto the mounting frame 31 through the first weakening groove 34, and the two clamping plates 372 can be stretched open, so that the clamping plates 372 are deformed through the second weakening groove 371 and opened until the card block 374 can be inserted into the corresponding card slot 375, thereby effectively preventing the metal foil strip coil from being broken by 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 rope 381 is fixedly connected to the middle part of the side wall of the two clamping plates 372 which are separated from each other, and a first limiting sleeve 382 is fixedly connected to the top of the two mounting bases 37. The other ends of the two steel wire ropes 381 are movably inserted into the first limiting sleeve 382 and the multiple wire threading grooves 38 opened on the top of the mounting frame 31, and are movably inserted into the front end of the mounting frame 31, and the movable sleeve is provided with multiple second limiting sleeves 383, multiple second limiting sleeves 384, and multiple second limiting sleeves 385. The limiting sleeves 383 are all fixed to the outside of the arc-shaped bending plate 39, and the end of the steel wire rope 381 away from the clamping plate 372 is fixed to the limiting block 384. The end of the limiting block 384 facing the mounting frame 31 is movably overlapped on the outside of a second limiting sleeve 383 farthest from the mounting frame 31. The arc-shaped bending plate 39 is fixed to the front end of the mounting frame 31. The cross-section of the arc-shaped bending plate 39 is a U-shaped structure. A third weakening groove 391 is provided in the middle of the bottom arc-shaped surface of the arc-shaped bending plate 39, and multiple wire threading grooves 38 are connected through the 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 combined, 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 prompt the card block 374 to disengage from the card slot 375 respectively, thereby prompting the guide plate 35 to be reset and tilted under the rebound action of the first weakening groove 34, thereby facilitating 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 strips are transported to the welding platform 4 through the guide roller 2 by the uncoiler 1 for welding;

[0050] Step 2: Then, the precision alloy foil strip and other metal foil strips are transported by the No. 1 tension roller group 5 through the conveyor roller 6 to the hot stretching furnace 7 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. The cooled foil strips are conveyed to the No. 2 tension roller group 11 through the conveyor roller 6 and then enter the tensioning and leveling machine 12 for tensioning and leveling.

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

[0053] In summary, the temperature of precision alloy foil can be effectively controlled during heating, ensuring controllability and speed, and avoiding material loss, ensuring the removal of residual stress in the tissue during the foil heat treatment process. The device has a short length interval and the 12 sets of flexible connection between the front-end hot stretching and the rear-end straightening machines 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 tightening 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 scratching between the metal foil strip coil and the front ends of the four guide plates 35, and then the four top tightening 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 by 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 groove 34. Moreover, the triangular limit frame 103 can be synchronously limited and fixed by the arrangement of 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 card blocks 374 through the two third inclined surfaces arranged at the bottom end, 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. By setting the locking setting of the guide plate 35, the metal foil strip coil is prevented from being bounced up by the guide plate 35 and causing the material to collapse when the material is unloaded to the last section, which greatly improves the stability of the unloading. Moreover, when the metal foil strip coil is unloaded, the four pressing plates 101 are retracted and pressed together by the expansion 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 weakening groove 391, thereby prompting the two steel ropes 381 to pull the clamping plates 372, and the clamping plates 372 are deformed between the second weakening groove 371 and the mounting base 37, so that the blocks 374 are disengaged from the slots 375, and the guide plates 35 will automatically reset and tilt 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, and no manual intervention is required throughout the process.

Furthermore, to avoid unnecessary confusion regarding the essence of the present invention, well-known methods, processes, procedures, components, and circuits have not been described in detail.

[0056] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
