Description

Technical Field

[0001] The utility model relates to the field of steel component production, in particular to a bidirectional bending device for thin and flexible H-shaped cross-section steel components. Background Art

[0002] The steel component system has comprehensive advantages such as light weight, factory manufacturing, quick installation, short construction period, good seismic performance, fast investment recovery and less environmental pollution. Compared with reinforced concrete structures, it has unique advantages in the three aspects of "high, large and light". Globally, especially in developed countries and regions, steel components are reasonably and widely used in the field of construction engineering. Compared with thick components, thin and flexible components have greater bending bearing capacity and overall stability, and thus have better economy.

[0003] In the production process of steel components, steel billets are often bent by rolling with multiple gradually corrected rollers. Due to the characteristics of the H-section steel component shape, double-sided rolling is often used for rolling. During the forming process, the shape of the rollers is fixed, so only one specification of thin and flexible H-section steel components can be produced. When it is necessary to produce thin and flexible H-section steel components of other specifications, it is often necessary to replace the rollers of the corresponding specifications, which is relatively inconvenient.

[0024] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0025] See also Figure 1-4A bidirectional bending device for thin and flexible H-section steel members includes a first rolling mechanism 1. The first rolling mechanism 1 includes a first fixed frame 101. Two groups of first fixed frames 101 are symmetrically arranged. The interiors of the two groups of first fixed frames 101 are rotatably connected to a hollow shaft 102. The arrangement of the first fixed frame 101 can provide support for the hollow shaft 102. A first bidirectional screw 104 is rotatably connected to the interior of the hollow shaft 102. The outer side of the first bidirectional screw 104 is symmetrically threaded with a first rolling wheel 103. When the first bidirectional screw 104 rotates, it can drive the two groups of first rolling wheels 103 to move relative to or away from each other, so that a groove can be rolled out of the steel billet when the steel billet passes through the first rolling wheel 103. A through-hole 107 is symmetrically opened on the outer side of the hollow shaft 102. The first rolling wheel 103 passes through the through-hole 107. The first rolling wheel 103 is slidably connected to the hollow shaft 102. The through-hole 107 is provided for the first rolling wheel 103 to pass through. The outer wall of the hollow rotating shaft 102 is fixedly connected with a guide bar 105, and the outer side of the inner wall of the first rolling wheel 103 has a guide groove 106 adapted to the guide bar 105. The setting of the guide groove 106 and the guide bar 105 is used to guide the movement of the first rolling wheel 103.

[0026] An adjustment plate 108 is symmetrically and slidably connected to the interior of the first fixed frame 101. A through hole 110 is formed inside the adjustment plate 108, and the hollow rotating shaft 102 passes through the through hole 110. The side of the adjustment plate 108 close to the first rolling wheel 103 is rotatably connected to the second rolling wheel 109. The second rolling wheel 109 is configured to roll the steel billet. Hydraulic rods 112 are symmetrically and fixedly connected to both sides of the first fixed frame 101. The output end of the hydraulic rod 112 is fixedly connected to the adjustment plate 108. When the hydraulic rod 112 is started, it can drive the adjustment plate 108 and the second rolling wheel 109 to move, thereby adjusting the distance between the second rolling wheels 109 on both sides. First guide rods 111 are symmetrically and fixedly connected to the interior of the first fixed frame 101. The first guide rods 111 pass through the adjustment plate 108 and are slidably connected to the adjustment plate 108. The provision of the first guide rods 111 can guide the movement of the adjustment plate 108.

[0027] The second rolling mechanism 2 includes adjustment screws 202 threadedly connected to the interior of the first fixed frame 101. The roller frame 201 is rotatably connected to the opposing sides of the two sets of adjustment screws 202. The rollers 203 are rotatably connected to the interior of the roller frame 201. During operation, the adjustment screws 202 drive the roller frame 201 and the rollers 203 to move up and down, thereby adjusting the distance between the two sets of rollers 203 so that the rollers 203 can roll the steel billet to the desired height. A second guide rod 204 is symmetrically fixedly connected to the side of the roller frame 201 away from the rollers 203. The second guide rod 204 extends through the first fixed frame 101 and is slidably connected to the first fixed frame 101. The second guide rod 204 is provided to guide the up and down movement of the roller frame 201.

[0028] The adjustment mechanism 3 includes a movable plate 301 fixedly connected to opposite sides of the two first fixed frames 101. Ribs 303 are fixedly connected to both sides of the first fixed frames 101. The ribs 303 are fixedly connected to the movable plates 301. The ribs 303 are provided to further connect and secure the first fixed frames 101 to the movable plates 301, thereby improving the stability of the connection between the movable plates 301 and the first fixed frames 101. The two sets of movable plates 301 are symmetrically threaded with second bidirectional screws 302 on their interiors. The two ends of the two sets of second bidirectional screws 302 are rotatably connected to fixed frames 304. When the second bidirectional screws 302 rotate, they can drive the two sets of movable plates 301 to move relative to or away from each other, thereby adjusting the spacing between the upper and lower first rolling wheels 103 to facilitate roll-bending the steel billet to a desired thickness.

[0029] Connecting studs 307 are fixed through each of the four corners of the fixed frame 304. Each set of connecting studs 307 is threadedly connected to an internally threaded tube 308 on the outside. When multiple devices are used simultaneously, the internally threaded tubes 308 of one set of devices can be threadedly fixed to the connecting studs 307 of another set of devices, thereby connecting and fixing two adjacent devices. The bottoms of the two sets of second bidirectional screws 302 are fixedly connected to worm gears 306. The outer sides of the two sets of worm gears 306 are meshedly connected to worms 305. The worm gears 305 are rotationally connected to the fixed frame 304. When the worm gears 305 rotate, they can drive the two sets of worm gears 306 to rotate synchronously, thereby achieving synchronized adjustment of the two sets of worm gears 306.

[0030] When in use, multiple devices are arranged vertically and in parallel, and the front group of internal threaded tubes 308 are screwed and fixed with the rear group of connecting studs 307, so as to realize the connection and fixation of two adjacent devices, and then the first bidirectional screw rods 104 of each group can be rotated, so that the first bidirectional screw rods 104 can drive the first rolling wheels 103 on both sides to move relative to or opposite to each other when rotating, so as to realize the adjustment of the spacing between the two adjacent first rolling wheels 103 to the required width, so as to meet the requirements of rolling out grooves of different widths of the steel billet (i.e., the concave part of the H-shaped steel), and then the hydraulic rod 112 is started, so that the hydraulic rod 112 drives the adjustment plate 108 and the second rolling wheel 109 to move, so as to adjust the spacing between the two adjacent second rolling wheels 109 to the required width, so as to meet the requirements of rolling the steel billet to different widths (i.e., the width of the H-shaped steel), and then rotate. The worm 305 can drive the worm wheels 306 and the second bidirectional screw 302 on both sides to rotate when the worm 305 rotates. When the worm 305 rotates, it can drive the two sets of movable plates 301 and the first fixed frame 101 to move relative to each other until the upper and lower sets of first rolling wheels 103 are adjusted to the required styles to meet the needs of rolling the steel billet to different thicknesses (i.e., the thickness of the H-shaped steel). Then, the upper and lower sets of adjusting screws 202 are rotated so that the adjusting screws 202 can drive the roller frame 201 and the rolling roller 203 to move up and down when rotating, thereby adjusting the distance between the upper and lower sets of rolling rollers 203 to the required distance, thereby meeting the needs of rolling the steel billet to the required height (i.e., the height of the H-shaped steel), so that the steel billet can be rolled to the required shape by each set of first rolling wheels 103, second rolling wheels 109 and rolling rollers 203 when passing through the entire device during the conveying process.

They are not intended to limit the present invention in any form. Any person with ordinary knowledge in the technical field can, without departing from the scope of the technical features of the present invention, make partial changes or modifications to the technical contents disclosed in the present invention and make equivalent embodiments without departing from the technical features of the present invention.
