Description

Technical Field

[0001] The utility model relates to steel material correction equipment, in particular to an adjustable steel material deformation correction device. Background Art

[0002] Commonly used steel materials in steel structure construction include steel plates, H-beams, channels, and I-beams. Steel plates typically come in single sheets and must be cut to size during use. Traditionally, steel plate cutting is done using plasma or flame cutting. Lasers or water jets are particularly impractical for thicker steel plates, requiring flame cutting. Both flame and plasma cutting methods are thermal, generating thermal stress that can cause severe deformation of the cut steel, rendering it unusable and requiring repair. H-beams, channels, and I-beams are formed from billets or ingots through pressure to achieve a specific shape, size, and properties. Over time, these materials can deform due to external forces, the effects of stacking and compression, and even during welding during the steel structure construction process. Deformed steel requires repair and correction, as this can affect its performance and even lead to safety hazards. Currently, simple correction methods for these steel materials on construction sites often use tools like pipe wrenches, wrenches, and hammers. This approach is not only ineffective, but also time-consuming and physically taxing for workers. Utility Model Content

DETAILED DESCRIPTION

[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments. Figures 1 to 6An adjustable steel deformation correction device comprises a work platform 1, with two adjustable top plate groups 2 fixed side by side on one side of the work platform 1. The adjustable top plate groups 2 include connecting plates 9, with inverted T-shaped slide bars 8 connected at both ends of the connecting plates 9. Seven-shaped plates 7 are symmetrically arranged on both sides of the lower end of the slide bars 8, and the lower ends of the seven-shaped plates 7 are fixedly connected to the bottom plate 6. Hydraulic jacks 5 are fixedly installed on the outside of the two horizontally parallel adjustable top plate groups 2. A pressure block 4 is installed on the top of the hydraulic jacks 5, and the center line of the pressure block 4 is perpendicular to the center line of the adjustable top plate groups 2. The hydraulic jacks 5 are connected to a hydraulic pump 10 via a high-pressure hose 11. The center lines of the pressure block 4 and the hydraulic pump 10 coincide and are located outside the symmetry axis of the two adjustable top plate groups 2. The pressure block 4 includes a bottom panel 41, the top of the bottom panel 41 is perpendicularly connected to the top panel 42 via a middle support plate 43, and reinforcement plates 44 are fixedly arranged on both sides of the middle support plate 43. The reinforcing plate 44 is in the shape of a right-angled trapezoid, and its upper and lower end surfaces are connected to the inner side surfaces of the fixed top plate 42 and the bottom plate 41 respectively.

[0018] The cross section of the seven-shaped plate 7 is "7" shaped and symmetrical to each other, and its lower end is fixedly welded to the bottom plate 41 (such as Figure 3 As shown). An inverted "T"-shaped groove is formed between the symmetrical seven-shaped plates 7, and is matched and connected with the lower end of the inverted "T"-shaped slide bar 8, so that the slide bar 8 can slide left and right in the inverted "T"-shaped groove.

[0019] The working platform 1 is designed with reasonable size according to the position relationship of the adjustable top plate group 2, the workpiece to be shaped 3, the pressure block 4 and the hydraulic jack 5; the adjustable top plate group 2 is divided into two groups on the left and right, and each adjustable top plate group 2 is composed of two bottom plates 6, four seven-shaped plates 7 (each two are symmetrical), two slide bars 8 and a connecting plate 9 (such as Figure 1 As shown). The seven-shaped plates 7 symmetrically fixed on the bottom plate 6 form an inverted "T"-shaped groove to clamp the lower end of the slide bar 8 so that the slide bar 8 can adjust its position left and right. The slide bar 8 is connected by a connecting plate 9 to enhance the strength of the slide bar 8 (as shown). Figure 2 As shown). The pressing block 4 is assembled by assembling steel plates (as shown). Figures 4 to 6 As shown), the pressure block 4 is mainly used to connect the pressure transfer between the hydraulic jack 5 and the workpiece 3 to be shaped.

[0020] The utility model can face different deformed workpieces (such as flat plates, angle steels, and channel steels). The workpiece 3 to be straightened can be placed on the outside of the adjustable top plate group 2 by adjusting the position of the slide rod 8. The hydraulic pump 10 is used to pressurize the hydraulic jack 5 through the high-pressure hose 11 to produce a telescopic function. The piston rod of the hydraulic jack 5 corrects the workpiece 3 to be straightened through the pressure block 4, ensuring the straightness requirement of the workpiece during the correction process and greatly improving the work efficiency of steel straightening.

[0021] The hydraulic jack 5 is selected according to the pressure required for the workpiece 3 to be corrected, and the model is: DYG500-200, the pressure is: 500t, and the stroke is: 200mm.

[0022] A steel structure factory has undertaken the task of manufacturing a large number of chain beam spare parts of different lengths. The total length of the chain beams has different specifications such as 1m, 2m, 3m, and 5m. During the production process, the biggest challenge is to calibrate the steel plates of different chain chain specifications. If the steel plates are directly cut and spliced, the quality of the product cannot be guaranteed.

[0023] In the past, chain beam spare parts were manufactured after cutting, with different temporary fixtures made for different chain beam steel plates of different lengths, and the steel plates were adjusted using jacks. However, with this calibration device, the position of the adjustable top plate group 2 can be adjusted to ensure the correct position of the steel plates for 1m, 2m, 3m, and 5m, respectively. The hydraulic jack 5 pushes the pressure block 2 to press the steel plates to achieve calibration. In this case, it can quickly calibrate steel plates of different lengths, improving the production efficiency and quality of spare parts manufacturing.
