Abstract
Description
Technical Field
[0001] This utility model relates to the field of metal processing equipment technology, specifically an anti-warping shearing device for a high-precision steel coil shearing machine. Background Technology
[0002] In the steel processing industry, steel coil shearing machines are key equipment for cutting coiled steel into plates of various specifications. As the manufacturing industry continues to increase its requirements for the precision and quality of steel processing, higher challenges are also being placed on the performance of steel coil shearing machines. In the actual shearing process, due to various factors such as the uneven stress distribution of the steel itself, the shearing force of the shearing machine blades, and the instantaneous stress release of the plate after shearing, the sheared plates are very prone to warping.
[0003] While some existing steel coil shearing machines are equipped with anti-warping measures, the results are not ideal. Some machines use simple clamping devices to press the surface of the steel coil before shearing in an attempt to reduce warping. However, this method often cannot accurately adapt to steels of different thicknesses, materials, and hardnesses. For some thicker or special steels, it is difficult to provide sufficient clamping force to suppress warping. Therefore, those skilled in the art have provided an anti-warping shearing device for high-precision steel coil shearing machines to solve the problems mentioned in the background art. Utility Model Content
[0004] The purpose of this invention is to provide an anti-warping shearing device for a high-precision steel coil shearing machine to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] An anti-warping shearing device for a high-precision steel coil shearing machine includes a steel coil cutting table, a steel coil leveling mechanism, and a steel coil cutting mechanism. The upper surface of the steel coil cutting table has a cutting opening. The steel coil leveling mechanism includes two fixed beams. The front of both fixed beams is connected to the steel coil cutting table. The sides of the two fixed beams that are close to each other have sliding grooves. Sliding blocks are slidably connected inside the two sliding grooves.
[0007] As a further improvement of this utility model, a first bearing is fixedly embedded on one side of the two sliding blocks that are close to each other and on one side of the two fixed beams that are close to each other.
[0008] As a further improvement of this utility model: each of the first bearings has a rotating shaft fixedly connected to its inner ring, and a steel coil leveling roller is fixedly connected to one end of each set of rotating shafts that is close to each other.
[0009] As a further embodiment of this utility model: a drive motor is fixedly connected to the back of one of the fixed beams, and the output end of the drive motor is connected to one of the rotating shafts through a coupling.

[0011] As a further improvement of this utility model: the bottom surface of the steel coil cutting table is fixedly connected to two support legs, and the bottom surface of each of the two support legs is fixedly connected to a base.
[0012] As a further embodiment of this utility model: the steel coil cutting mechanism includes two vertical beams, the upper surfaces of the two vertical beams are fixedly connected to a horizontal beam, and the bottom surfaces of the two vertical beams are connected to the steel coil cutting table.
[0013] As a further embodiment of this utility model: a hydraulic tank is installed on the upper surface of the crossbeam, and two piston rods are installed at the output end of the hydraulic tank. The output ends of the two piston rods are fixedly connected to a support plate, and a steel coil shearing blade is fixedly connected to the bottom surface of the support plate.
[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0024] Please see Figures 1-5In this embodiment of the present invention, an anti-warping shearing device for a high-precision steel coil shearing machine includes a steel coil cutting table 1, a steel coil leveling mechanism 2, and a steel coil cutting mechanism 3. The upper surface of the steel coil cutting table 1 is provided with a cutting opening 6. The steel coil leveling mechanism 2 includes two fixed beams 201. The front sides of the two fixed beams 201 are connected to the steel coil cutting table 1. The sides of the two fixed beams 201 that are close to each other are provided with sliding grooves 206. Sliding blocks 207 are slidably connected inside the two sliding grooves 206. The overall structure is convenient and efficient to operate, greatly improving the shearing efficiency and the finished product qualification rate, and is suitable for high-precision steel coil processing scenarios.
[0025] Two sliding blocks 207 and two fixed beams 201 are each fixedly inlaid with a first bearing 202 on their adjacent sides. The inner ring of each first bearing 202 is fixedly connected to a rotating shaft 203. The adjacent ends of each set of rotating shafts 203 are fixedly connected to a steel coil leveling roller 204. A drive motor 205 is fixedly connected to the back of one of the fixed beams 201. The output end of the drive motor 205 is connected to one of the rotating shafts 203 through a coupling. The upper surfaces of the two sliding blocks 207 are each fixedly inlaid with a second bearing 208. The inner rings of the two second bearings 208 are each fixedly connected to a threaded rod 209. The outer surfaces of the two threaded rods 209 are threadedly connected to the fixed beams 201. A handle 210 is fixedly connected to one end of each threaded rod 209. This not only allows the equipment to fully level the steel coil before shearing, effectively eliminating the warping of the steel coil itself and preventing deformation of the sheet metal after shearing from the source, but also allows the equipment to meet the leveling operation of steel of different thicknesses, thereby greatly increasing the applicability of the equipment.
[0026] The bottom surface of the steel coil cutting table 1 is fixedly connected to two support legs 4, and the bottom surface of each support leg 4 is fixedly connected to a base 5. The steel coil cutting mechanism 3 includes two vertical beams 301, and the upper surfaces of the two vertical beams 301 are fixedly connected to a crossbeam 302. The bottom surfaces of the two vertical beams 301 are connected to the steel coil cutting table 1. A hydraulic tank 303 is installed on the upper surface of the crossbeam 302. Two piston rods 304 are installed at the output end of the hydraulic tank 303. The output ends of the two piston rods 304 are fixedly connected to a support plate 305. The bottom surface of the support plate 305 is fixedly connected to a steel coil shearing blade 306, which enables the equipment to automatically cut steel coils, thereby greatly increasing the cutting efficiency of the equipment for steel.
[0027] The working principle of this utility model is as follows: The steel coil is first pre-treated by the steel coil leveling mechanism 2. After the drive motor 205 is started, it drives the rotating shaft 203 to rotate through the coupling. The steel coil leveling roller 204 rolls and levels the steel coil to eliminate the original warping. If the thickness of the steel coil is different, the handle 210 can be turned at the same time to drive the threaded rod 209 to rotate in the second bearing 208, so that the sliding block 207 rises and falls along the sliding groove 206 to adjust the gap of the leveling roller. The leveled steel coil is then transported to the steel coil cutting table 1. The hydraulic box 303 drives the piston rod 304 to extend and retract synchronously, which drives the steel coil shearing blade 306 under the support plate 305 to move vertically downward and precisely cooperate with the cutting opening 6 on the steel coil cutting table 1 to complete the shearing of the steel coil.
