Description

Technical Field

[0001] This utility model relates to the field of coil bending technology, specifically a segmented coil bending device. Background Technology

[0002] A coil bending and pressing device is a piece of equipment used for bending and pressing coiled materials. Segmented coil bending and pressing devices are commonly used in industrial production for processing various coiled materials into specific shapes or to treat their properties. Coiled materials typically include strips of various materials such as metal, plastic, paper, and rubber. The device consists of multiple independent pressure roller segments. Each pressure roller segment can independently adjust its pressure and position, allowing for the application of different pressure levels to meet the processing requirements of different parts of the coil, thus achieving more precise bending and pressing operations.

[0003] Existing coil bending and pressing devices generally use the rotation of a lower leveling roller to drive the coil material to move and process within the equipment. When the sheet material is placed between the upper and lower leveling rollers of the leveling machine, the rotation of the lower leveling roller generates friction with the surface of the sheet material, thereby moving the sheet material forward. At the same time, the upper and lower leveling rollers apply pressure to the sheet material, achieving the purpose of leveling through repeated bending and straightening. However, existing upper leveling rollers lack a synchronous rotation device, which results in a lack of synchronized torque input between the upper and lower leveling rollers. Because the upper leveling roller lacks a synchronous rotation device, when the lower leveling roller rotates and drives the sheet material to move, the upper leveling roller cannot rotate synchronously with it. This causes uneven contact and force distribution between the sheet material and the upper and lower leveling rollers, affecting the leveling quality. Utility Model Content

[0004] The purpose of this invention is to provide a segmented roll bending and pressing device to solve the problem mentioned in the background art that the existing upper leveling roller lacks a synchronous rotation device, which results in the lack of synchronous torque input between the upper and lower leveling rollers. Because the upper leveling roller lacks a synchronous rotation device, when the lower leveling roller rotates and drives the board to move, the upper leveling roller cannot rotate synchronously with it. This makes the contact and force distribution between the board and the upper and lower leveling rollers uneven, affecting the leveling quality.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a segmented roll material bending and pressing device, comprising a frame, a conveying section, and a pressing section:

[0006] The conveying section is located at the top of the frame. It has several conveying rollers that are laterally rotatable inside the frame. A power shaft is rotatably mounted inside the frame and meshes with the conveying rollers. Several transmission shafts are vertically rotatable inside the frame, with their bottoms meshing with the power shaft. The power shafts rotate to drive the conveying rollers and transmission shafts to rotate. The pressing section is located at the top of the frame and has a support frame at the top of the frame. A lifting frame is vertically slidably mounted inside the support frame. A pressing roller is laterally rotatable inside the lifting frame. A bevel gear f is vertically rotatable inside the support frame. The transmission shaft is vertically embedded in and slidably connected to the bevel gear f.

[0007] By adopting the above technical solution, the rotation of the power shaft can simultaneously drive the conveyor roller and the drive shaft to rotate. The rotation of the conveyor roller enables the conveying of the roll material, while the rotation of the drive shaft can transmit power to the bevel gear f of the lower pressing part, thereby driving the lower pressing roller to rotate. This allows the lower pressing roller to perform bending and pressing operations on the roll material while it is being conveyed, thus achieving the linkage between conveying and bending / pressing.

[0008] Preferably, the conveying unit also has a bevel gear a disposed on the side of the conveying roller, and a plurality of bevel gears b are arranged on the side of the power shaft, the plurality of bevel gears b respectively meshing with bevel gear a, and a motor is disposed on the side of the frame, the output end of the motor being connected to the power shaft.

[0009] By adopting the above technical solution, the power shaft can be rotated by a motor, and the bevel gear b on the power shaft meshes with the bevel gear a on the side of the conveyor roller, thereby transmitting power to the conveyor roller.

[0010] Preferably, the conveying unit also has a bevel gear d disposed at the bottom of the drive shaft, and a plurality of bevel gears c are arranged on the side of the power shaft, and the plurality of bevel gears c respectively mesh with the bevel gear d.

[0011] By adopting the above technical solution, when the power shaft rotates, the power can be transmitted to the transmission shaft through the meshing of the bevel gear c on the power shaft and the bevel gear d at the bottom of the transmission shaft, so that the transmission shaft can rotate stably vertically.

[0012] Preferably, two pressing parts are arranged side by side, and each pressing part also has a hydraulic telescopic rod disposed on the top of the support frame, the output end of which is connected to the top of the lifting frame.

[0013] By adopting the above technical solution, the vertical sliding of the lifting frame inside the support frame can be controlled by the extension and retraction of the hydraulic telescopic rod, thereby adjusting the height position of the lower pressure roller. The parallel arrangement of two lower pressure sections allows for segmented bending and pressing of the roll material.

[0014] Preferably, the pressing part also has a bevel gear e disposed on the side of the pressing roller, which meshes with a bevel gear f.

[0015] By adopting the above technical solution, when the drive shaft drives the bevel gear f to rotate, the power is transmitted to the lower pressure roller through the meshing of the bevel gear f with the bevel gear e on the side of the lower pressure roller, so that the lower pressure roller can rotate synchronously with the conveying roller.

[0016] Preferably, the pressing part also has a hexagonal groove formed inside the bevel gear f, and the top of the drive shaft is a hexagonal prism, which passes vertically through the hexagonal groove and is vertically slidably connected to the bevel gear f.

[0017] By adopting the above technical solution, it can be ensured that the drive shaft can transmit power to the bevel gear f, while allowing the bevel gear f to slide vertically on the drive shaft as the lifting frame and the lower pressure roller rise and fall.

[0018] Preferably, the conveying roller and the pressure roller are arranged alternately, with the pressure roller located directly above the gap between the two conveying rollers.

[0019] By adopting the above technical solution, the lower pressure roller can accurately bend and compress the roll material during the conveying process of the roll material.

[0020] Compared with the prior art, the beneficial effects of this utility model are: by providing a conveying part and a pressing part, the rotation of the power shaft can simultaneously drive the conveying roller and the transmission shaft to rotate. The rotation of the conveying roller can realize the conveying of the roll material, while the rotation of the transmission shaft can transmit power to the bevel gear f of the pressing part, thereby driving the pressing roller to rotate. This allows the pressing roller to perform bending and pressing operations on the roll material while conveying it, thus realizing the linkage between conveying and bending / pressing.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Example 1

[0030] Please see Figure 1 , Figure 2 and Figure 3 This embodiment provides a technical solution: a segmented roll material bending and pressing device, including a frame 1, a conveying section 2, and a pressing section 3.

[0031] The conveying unit 2 is located on top of the frame 1. The conveying unit 2 has several conveying rollers 201 that are laterally rotatably arranged inside the frame 1. A power shaft 203 is rotatably arranged inside the frame 1, and the power shaft 203 is meshed with the several conveying rollers 201. Several transmission shafts 206 are vertically rotatably arranged inside the frame 1, and the bottom of the transmission shafts 206 is meshed with the power shaft 203. The rotation of the power shaft 203 drives the several conveying rollers 201 and the transmission shafts 206 to rotate. The pressing unit 3 is located on top of the frame 1. The pressing unit 3 has a support frame 301 located on top of the frame 1. A lifting frame 302 is vertically slidably arranged inside the support frame 301. The lifting frame 302 has a horizontally rotating lower pressure roller 304 inside, and the support frame 301 has a vertically rotating bevel gear f306 inside. The drive shaft 206 is vertically embedded in the bevel gear f306 and slidably connected to the bevel gear f306. The rotation of the power shaft 203 can simultaneously drive the conveying roller 201 and the drive shaft 206 to rotate. The rotation of the conveying roller 201 can realize the conveying of the roll material, while the rotation of the drive shaft 206 can transmit power to the bevel gear f306 of the lower pressure part 3, thereby driving the lower pressure roller 304 to rotate. This allows the lower pressure roller 304 to perform bending and pressing operations on the roll material while conveying it, realizing the linkage between conveying and bending / pressing.

[0032] Example 2

[0033] Please see Figure 4 , Figure 5 and Figure 6 This embodiment provides a technical solution: a segmented roll forming device, including a conveying section 2, a conveying roller 201, and a power shaft 203.

[0034] The conveying unit 2 also has a bevel gear a202 disposed on the side of the conveying roller 201, and a plurality of bevel gears b204 are arranged on the side of the power shaft 203, which are respectively meshed with the bevel gear a202. A motor 208 is disposed on the side of the frame 1, and the output end of the motor 208 is connected to the power shaft 203. The motor 208 can drive the power shaft 203 to rotate. The bevel gears b204 on the power shaft 203 mesh with the bevel gears a202 on the side of the conveying roller 201, thereby transmitting power to the conveying roller 201.

[0035] The conveying unit 2 also has a bevel gear d207 disposed at the bottom of the drive shaft 206. Several bevel gears c205 are arranged on the side of the power shaft 203, and the several bevel gears c205 are respectively meshed with the bevel gear d207. When the power shaft 203 rotates, the power is transmitted to the drive shaft 206 through the meshing of the bevel gears c205 on the power shaft 203 with the bevel gears d207 at the bottom of the drive shaft 206, so that the drive shaft 206 can rotate stably vertically.

[0036] Example 3

[0037] Please see Figure 4 , Figure 5 and Figure 6 This embodiment provides a technical solution: a segmented roll material bending and pressing device, including a pressing part 3, a pressing roller 304, and a bevel gear f306.

[0038] Two pressing sections 3 are arranged side by side. Each pressing section 3 also has a hydraulic telescopic rod 303 located on top of the support frame 301. The output end of the hydraulic telescopic rod 303 is connected to the top of the lifting frame 302. The extension and retraction of the hydraulic telescopic rod 303 can be used to control the vertical sliding of the lifting frame 302 inside the support frame 301, thereby adjusting the height position of the pressing roller 304. The two pressing sections 3 arranged side by side can perform segmented bending and pressing on the roll material.

[0039] The lower pressing part 3 also has a bevel gear e305 disposed on the side of the lower pressing roller 304. The bevel gear e305 is meshed with the bevel gear f306. When the drive shaft 206 drives the bevel gear f306 to rotate, the power is transmitted to the lower pressing roller 304 through the meshing of the bevel gear f306 with the bevel gear e305 on the side of the lower pressing roller 304, so that the lower pressing roller 304 can rotate synchronously with the conveying roller 201.

[0040] The lower pressing part 3 also has a hexagonal groove 307 opened inside the bevel gear f306. The top of the drive shaft 206 is a hexagonal prism. The drive shaft 206 passes vertically through the hexagonal groove 307 and is vertically slidably connected to the bevel gear f306. This ensures that the drive shaft 206 can transmit power to the bevel gear f306 while allowing the bevel gear f306 to slide vertically on the drive shaft 206 as the lifting frame 302 and the lower pressing roller 304 rise and fall.

[0041] The conveying roller 201 and the lower pressure roller 304 are arranged alternately. The lower pressure roller 304 is located directly above the gap between the two conveying rollers 201, so that the lower pressure roller 304 can accurately bend and press the roll material during the conveying process of the roll material being conveyed by the conveying roller 201.

[0042] Working principle: First, power is supplied to the device, then the motor 208 is started. The output end of the motor 208 drives the power shaft 203 to rotate. Several bevel gears b204 arranged on the side of the power shaft 203 mesh with the bevel gears a202 on the side of the conveyor rollers 201. As the power shaft 203 rotates, the bevel gears b204 drive the bevel gears a202 to rotate, thereby causing the several conveyor rollers 201 to rotate synchronously, realizing the conveying of the roll material. At the same time, the bevel gears b204 on the side of the power shaft 203 mesh with the bevel gears a202 on the side of the conveyor rollers 201. Gear C205 meshes with bevel gear D207 at the bottom of drive shaft 206. The rotation of power shaft 203 drives drive shaft 206 to rotate vertically. Since the top of drive shaft 206 is a hexagonal prism and passes vertically through the hexagonal groove 307 inside bevel gear F306, drive shaft 206 transmits power to bevel gear F306, causing bevel gear F306 to rotate. Bevel gear F306 meshes with bevel gear E305 on the side of lower pressure roller 304. The rotation of bevel gear F306 drives bevel gear E305 to rotate. Rotation of 305 causes the lower pressure roller 304 to rotate. The lower pressure roller 304 and the conveyor roller 201 are staggered, with the lower pressure roller 304 located directly above the gap between the two conveyor rollers 201. When the lower pressure roller 304 rotates, it can accurately perform bending and pressing operations on the roll material during the conveying process of the roll material being transported by the conveyor roller 201, realizing the linkage between conveying and bending and pressing. When it is necessary to adjust the degree of bending and pressing, the lifting frame 302 slides vertically inside the support frame 301 by controlling the extension and retraction of the hydraulic telescopic rod 303. Since the bevel gear f306 can slide up and down along the transmission shaft 206, the power transmission will not be affected when the height of the lower pressure roller 304 is adjusted, ensuring that the lower pressure roller 304 can rotate normally for bending and pressing operations at different heights. The two parallel lower pressing parts 3 can perform segmented bending and pressing on the roll material. According to the actual situation of the roll material and the bending and pressing requirements, the height of each lower pressure roller 304 can be flexibly adjusted to achieve bending and pressing at different degrees and positions, improving the bending and pressing effect and adaptability.
