Description

Technical Field

[0001] The present application relates to the technical field of metal bellows processing equipment, and particularly to a metal bellows male wave flattening device. Background Art

[0002] A metal bellows male wave flattening device is a device used for pressing metal bellows. The main purpose is to change the shape and structure of the metal bellows by flattening it. Among them, the male wave refers to the corrugation. The purpose is to ensure that the corrugated structure of the metal bellows will not be damaged during the flattening process of the metal bellows, so as to be used in a flat anchorage system, mainly for box-shaped slab beams, transverse prestressed tendons in three-dimensional prestressed continuous steel girder beams, etc.

[0003] After retrieval, the publication number is CN216175804U, which discloses a flat tube machine for processing metal bellows. It includes a main frame, pressure rollers, movable rollers, and a motor. The main frame is provided with a movable frame inside; a plurality of pressure rollers are horizontally and equidistantly arranged at the lower side inside the main frame; a plurality of movable rollers are horizontally and equidistantly arranged at the lower end of the movable frame; a chute is arranged at the position of the main frame corresponding to the movable rollers; the movable rollers are slidably connected with the chute; one end of the pressure rollers and the movable rollers extends to the outside of the main frame and is provided with a first gear; a first transmission chain is respectively arranged at the position of the first gear of the plurality of pressure rollers and the movable rollers; two first gears at one end extend outward and are provided with a second gear; a second transmission chain is arranged on one side of the second gear to drive the pressure rollers and the movable rollers to rotate and flatten the bellows.

[0004] However, although the prior art can flatten the metal bellows, due to the structure of the pressure rollers and the movable rollers, during flattening, by adjusting the distance between the pressure rollers and the movable rollers and rotating them to flatten the metal bellows, in this process, because the rotation directions of the pressure rollers and the movable rollers are different, the metal bellows placed therein cannot be effectively flattened. At the same time, only flattening the metal bellows through a single flattening mechanism will also cause the metal bellows to rebound and reset, and repeated flattening is required to obtain a flat metal bellows.

[0005] Therefore, it is necessary to provide a metal bellows male wave flattening device to solve the above problems.

[0006] It should be noted that the above information disclosed in this background art section is only used to understand the background art of the concept of the present application, and therefore, it may include information that does not constitute the prior art. Utility Model Content

[0008] The technical solution adopted by this application to solve its technical problems is as follows:

[0009] A metal bellows positive wave flattening device includes an upper clamping frame and a lower clamping frame for flattening the metal bellows.

[0036] In order to enable those skilled in the art of this technology to better understand the solution of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts shall fall within the protection scope of the present application.

[0037] Please refer to Figures 1-4 , the embodiment provided by the present utility model:

[0038] A metal bellows positive wave flattening device includes an upper clamping frame 3 and a lower clamping frame 1 for flattening the metal bellows. A plurality of flattening assemblies 5 are respectively rotatably connected inside the upper clamping frame 3 and the lower clamping frame 1. The metal bellows to be flattened are pushed into them from one end of the upper clamping frame 3 and the lower clamping frame 1, and the flattening assemblies 5 in the upper clamping frame 3 and the lower clamping frame 1 are arranged in a one-to-one correspondence up and down.

[0039] The flattening assemblies 5 located inside the lower clamping frame 1 rotate synchronously through a transmission mechanism 4. The transmission mechanism 4 includes a driving gear 41, a driven gear 42 and a synchronous belt 43. The inside of the driving gear 41 is key-connected to the side wall of one of the rotating shafts 52, and the inside of the driven gear 42 is respectively key-connected to the side walls of other rotating shafts 52. The driving gear 41 is respectively connected to a plurality of driven gears 42 through the synchronous belt 43. One of the flattening assemblies 5 is fixedly installed on the output shaft of the stepper motor 8. The stepper motor 8 is installed on the side wall of the lower clamping frame 1, and the rotating shaft 52 at the other end of the pressure roller 51 connected to the driving gear 41 is fixedly installed on the output shaft of the stepper motor 8 through a coupling;

[0040] The driving roller 51 with the driving gear 41 is driven to rotate by the stepping motor 8. Under the transmission of the transmission assembly, the driving roller 51 inside the lower clamping frame 1 can rotate inside it, so as to realize the process of pressing the metal bellows into it while rotating, and then flattening the metal bellows through the corresponding driving roller 51 in the upper clamping frame 3.

[0041] Among them, in order to avoid deformation of the side wall of the metal bellows during the flattening process, the flattening assembly 5 includes a driving roller 51, a rotating shaft 52, an inner concave arc surface 53 and a groove plate 54. The rotating shaft 52 is fixedly connected to both ends of the driving roller 51 respectively. Through holes are respectively formed in the side walls of the upper clamping frame 3 and the lower clamping frame 1. The end portions of the rotating shaft 52 respectively pass through the through holes and are rotationally connected to the side walls of the upper clamping frame 3 and the lower clamping frame 1 through bearing seats. The side wall of the driving roller 51 is in an inner concave arc surface 53 for one circle, and groove plates 54 for matching with the corrugated grooves on the side wall of the metal bellows are fixedly connected to the side wall of the driving roller 51 respectively. The groove plates 54 are arranged obliquely and bent on the side wall of the driving roller 51.

[0042] When the upper and lower driving rollers 51 flatten the metal bellows during rotation, the inner concave arc surface 53 on the surface is used to make the metal bellows bend along the surface. At the same time, the groove plates 54 matching with the corrugated grooves on the side wall of the metal bellows are used to make the formed notch correspond to the corrugated groove formed on the surface of the metal bellows, so as to prevent the deformation of the side wall of the metal bellows during the flattening process of the metal bellows.

[0043] Lifting assemblies 6 for adjusting the distance between the upper clamping frame 3 and the lower clamping frame 1 are respectively installed on the middle side walls of the upper clamping frame 3 and the lower clamping frame 1. The lifting assembly 6 includes a first mounting plate 61, an electric push rod 62 and a first fixing plate 63. The side walls of the first mounting plate 61 are respectively fixedly installed on both side walls of the lower clamping frame 1. The bottom of the electric push rod 62 is installed on the top surface of the first mounting plate 61. The top end of the telescopic shaft of the electric push rod 62 is fixedly installed with the bottom surface of the first fixing plate 63. The side walls of the first fixing plate 63 are respectively installed on both side walls of the upper clamping frame 3.

[0044] Through the extension and shortening of the telescopic rod of the electric push rod 62, the upper clamping frame 3 can be close to or far away from the lower clamping frame 1, so that the distance between the upper and lower driving rollers 51 can be changed, so as to adjust the flattening degree of the metal bellows.

[0045] On both sides of the upper clamping frame 3 and the lower clamping frame 1, limiting components 7 are respectively installed. The limiting component 7 includes a second mounting plate 71, a sliding rod 72, a second fixing plate 73, a sliding hole 74 and a limiting disk 75. The second mounting plates 71 are respectively fixedly installed on the side walls at both ends of the lower clamping frame 1. The bottom surface of the sliding rod 72 is fixedly installed with the top surface of the second mounting plate 71. The second fixing plates 73 are respectively fixedly installed on the side walls at both ends of the upper clamping frame 3. The sliding hole 74 is formed in the top surface of the second fixing plate 73. The second fixing plate 73 is slidably connected with the side wall of the sliding rod 72 through the sliding hole 74.

[0046] During the process that the lifting component 6 controls the upper clamping frame 3 to be able to approach or move away from the lower clamping frame 1, by sliding the sliding rod 72 in the sliding hole 74 of the second fixing plate 73, it is ensured that the upper clamping frame 3 and the lower clamping frame 1 move up and down in the vertical direction, thereby ensuring the one-to-one correspondence of the upper and lower pressure rollers 51 and preventing the occurrence of misalignment.

[0047] The above are only the preferred embodiments of the present application and are not used to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included within the protection scope of the present application.
