Description

Technical Field

[0001] The present invention relates to the technical field of steel structure correction equipment, and particularly to a steel structure processing and correction device and a correction method thereof. Background Art

[0002] In many fields such as modern architecture, bridges, and machinery manufacturing, steel structures are widely used due to their high strength, light self-weight, fast construction speed, etc. Steel structures are usually composed of various profiled steels (such as I-beams, channel steels, angle steels, etc.) combined by welding, bolt connection, etc. However, during the production process of steel structures, due to factors such as the initial deformation of raw materials, collisions during transportation and loading / unloading, and uneven stress during processing, steel structure components often have various shape deviations and deformation problems. Therefore, in the subsequent use process, the steel structure needs to be corrected. However, during the use of existing correction devices, most of them synchronously press the steel structure with pressing plates. When the surface deformations of the steel structure are different, the steel structure will be unevenly stressed during the downward pressing process, resulting in the situation of warping edges of the steel structure, which is extremely likely to cause accidental injuries to workers. At the same time, it may also cause secondary damage to the steel structure, reducing the correction effect of the device and also greatly increasing the waste of the steel structure. Therefore, a steel structure processing and correction device and a correction method thereof are specifically proposed. Summary of the Invention

When the first connecting rod 324 moves, it will drive the two ejector rods 325 to move together. When the two ejector rods 325 move, they will jack up the placement plate 112, realizing the movement of the placement plate 112 approaching several pressing plates 221, enhancing the force exerted by the equipment on the steel, greatly shortening the correction cycle, thus improving work efficiency, and at the same time reducing the situation of the steel splashing due to stress.

At the same time, the two air pipes 332 are flexible and have an extendable feature.

[0020] During use, first, the staff places the steel to be corrected on the top of the placement plate 112. At the same time, a number of anti-slip protrusions 113 on the top of the placement plate 112 will play a certain anti-slip role for the steel. Then, the hydraulic press 211 is started to drive the telescopic rod 212 to move. During the movement of the telescopic rod 212, it will slide inside the support frame 114. At the same time, when the telescopic rod 212 moves, it will drive the push plate 213 to move together. When the push plate 213 moves, it will drive a number of pressing plates 221 to move downward. When the number of pressing plates 221 moves, they will come into contact with the steel. At this time, the number of pressing plates 221 will move under the action of force. At this time, the movement state of the pressing plate 221 is that it will swing left and right when moving upward. When the pressing plate 221 swings left and right, it will rotate at the connection of a number of first support rods 222. At the same time, when the pressing plate 221 moves upward, it will drive the limit support bracket two 225 to move through the first support rod 222. When the limit support bracket two 225 moves, it will drive the slide bar 226 to slide inside the first chute 227. Through this pressing method, it is avoided that a number of pressing plates 221 simultaneously apply pressure to the steel, so as to adapt to steels with different surfaces, and to prevent the situation of warping caused by uneven force in different areas during the downward pressing process, thereby reducing the secondary damage to the steel and also reducing the accidental injury to the staff; During the downward movement of the push plate 213, it will drive the first push rod 321 to move together. During the movement of the first push rod 321, it will slide inside the workbench 111. At the same time, when the first push rod 321 moves, it will drive the second support rod 322 to move. At the same time, the first push rod 321 will slide inside the notch 323 on the back of the second support rod 322 through the action of the second connecting rod 327. At the same time, when the second support rod 322 is stressed, it will perform a flipping movement through the action of the fixed support 326. At this time, the second support rod 322 will drive the first connecting rod 324 to move upward through the action of the front chute. When the first connecting rod 324 moves, it will drive two ejector rods 325 to move together. When the two ejector rods 325 move, they will jack up the placement plate 112 upward, realizing the movement of the placement plate 112 and a number of pressing plates 221 approaching each other, improving the force applied by the equipment to the steel, greatly shortening the correction cycle, thereby improving work efficiency, and also reducing the situation of the steel flying due to stress; Meanwhile, during the downward movement of the second connecting rod 327, the second push rod 333 will be driven to slide into the cavity 331 under the action of the two fixed rods 335. When the two second push rods 333 move, they will drive the two pistons 334 to move together. When the two pistons 334 move inside the cavity 331, the air inside the cavity 331 will be compressed and then discharged through the air pipe 332. The gas discharged through the air pipe 332 will enter the two air bags 314. At this time, the two air bags 314 will expand under the influence of the gas. At the same time, the air pipe 332 is in a flexible state and can perform extension movement. When the two air bags 314 expand, they will push the two clamping plates 311 closer to each other. When the two clamping plates 311 approach each other, their bottoms will slide inside the second chute 315. The second chute 315 improves the stability of the clamping plate 311 during movement. When the two clamping plates 311 approach each other, they will clamp the steel, preventing the steel from shifting under force, thus greatly improving the accuracy of straightening and reducing the damage to the steel during the straightening process. When the two clamping plates 311 move, they will drive the sliding rod 312 to slide inside the support plate 316. At the same time, when the sliding rod 312 moves, it will squeeze the spring 313. Then, the spring 313 will contract and store energy under the limiting action of the support plate 316. When the pushing plate 213 moves upward, at this time, the air bag 314 is in a deflated state. The clamping plate 311 can be driven to reset by the resilience of the spring 313, which is convenient for subsequent use.

10. A correction method for a steel structure processing and correction device, characterized in that: Adopt a steel structure processing and straightening device as described in claim 9. The method includes the following steps: Step 1: When in use, first, the staff places the steel to be corrected on the top of the placement plate (112). At the same time, several anti-slip ridges (113) on the top of the placement plate (112) will play a certain anti-slip role for the steel. Then, start the hydraulic press (211) to drive the telescopic rod (212) to move. During the movement of the telescopic rod (212), it will slide inside the support frame (114). At the same time, when the telescopic rod (212) moves, it will drive the push plate (213) to move together. When the push plate (213) moves, it will drive several pressing plates (221) to move downward. When several pressing plates (221) move, they will come into contact with the steel. At this time, several pressing plates (221) will move under the action of force. At this time, the movement state of the pressing plate (221) is that it will swing left and right while moving upward. When the pressing plate (221) swings left and right, it will rotate at the connection of several first support rods (222). At the same time, when the pressing plate (221) moves upward, it will drive the limit support bracket two (225) to move through the first support rod (222). When the limit support bracket two (225) moves, it will drive the sliding strip (226) to slide inside the first chute (227). Through this pressing method, it is avoided that several pressing plates (221) simultaneously apply pressure to the steel, so as to adapt to steels with different surfaces, and to prevent the situation of warping caused by uneven force in different areas during the downward pressing process, thereby reducing the secondary damage to the steel and also reducing the accidental injury to the staff; Step 2: During the downward movement of the push plate (213), it will drive the first push rod (321) to move together. During the movement of the first push rod (321), it will slide inside the workbench (111). At the same time, when the first push rod (321) moves, it will drive the second support rod (322) to move. At the same time, the first push rod (321) will slide inside the notch (323) on the back of the second support rod (322) through the action of the second connecting rod (327). At the same time, when the second support rod (322) is stressed, it will perform a flipping movement through the action of the fixed support (326). At this time, the second support rod (322) will drive the first connecting rod (324) to move upward through the action of the front chute. When the first connecting rod (324) moves, it will drive two ejector rods (325) to move together. When the two ejector rods (325) move, they will lift the placement plate (112) upward, realizing the movement of the placement plate (112) and several pressing plates (221) approaching each other, enhancing the force applied by the equipment to the steel, greatly shortening the correction cycle, thereby improving work efficiency, and also reducing the situation of the steel flying due to stress; Step 3: While the second connecting rod (327) moves downward, it will drive the second push rod (333) to slide into the cavity (331) through the action of two fixed rods (335). When the two second push rods (333) move, they will drive the two pistons (334) to move together. When the two pistons (334) move inside the cavity (331), they will compress the air inside the cavity (331), and then discharge it through the air pipe (332). The gas discharged through the air pipe (332) will enter the two air bags (314). At this time, the two air bags (314) will expand under the influence of the gas. At the same time, the air pipe (332) is in a flexible state and can perform extension movement. When the two air bags (314) expand, they will push the two clamping plates (311) closer to each other. When the two clamping plates (311) move closer to each other, their bottoms will slide inside the second chute (315). Through the action of the second chute (315), the stability of the clamping plates (311) during movement is improved. When the two clamping plates (311) move closer to each other, they will clamp the steel, preventing the steel from shifting under force, thus greatly improving the accuracy of straightening and reducing the damage to the steel during the straightening process. When the two clamping plates (311) move, they will drive the sliding rod (312) to slide inside the support plate (316). At the same time, when the sliding rod (312) moves, it will squeeze the spring (313). Then, the spring (313) will contract and store energy under the limiting action of the support plate (316). When the pushing plate (213) moves upward, at this time, the air bag (314) is in a deflated state. Through the resilience of the spring (313), the clamping plate (311) can be driven to reset for subsequent use.
