Abstract
Description
Technical Field
[0001] This utility model belongs to the field of steel structure processing technology, and in particular provides a flat steel arc bending device. Background Technology
[0002] When processing steel structures, the corner bending of guardrail flat steel is generally done using specialized equipment. The disadvantages of this method are twofold: first, it requires the purchase of bending equipment, which is expensive; second, the bending equipment requires dedicated personnel for maintenance, resulting in high construction costs. Utility Model Content
[0003] The purpose of this utility model is to provide a bending device that solves the problem of purchasing bending equipment, while also saving labor maintenance costs and reducing construction costs.
[0004] This invention involves passing a flat steel bar through a hole in the middle of the vertical cylinder of the bending device, adjusting the bending dimensions of the flat steel bar, and then rotating the operating handle around the roller to make the stop bar press against the flat steel bar. Under the action of the external force of the stop bar, the flat steel bar gradually bends along the vertical cylinder until the bending arc of the flat steel bar meets the usage requirements.
[0005] This utility model includes a base 1, a vertical cylinder 2, a stop bar 3, a handle 4, a support plate 5, a sliding roller 6, and a roller shaft 7, which are used in combination. The vertical cylinder 2 is vertically welded to the base 1; the support plate 5 is welded to the top of the vertical cylinder 2; the sliding roller 6 and the roller shaft 7 form a rolling system, and the sliding roller 6 can rotate around the roller shaft 7; the roller shaft 7 is vertically welded to the top of the support plate 5; the handle 4 is vertically welded to the side of the sliding roller 6; and the stop bar 3 is vertically welded to the lower side of the front 1 / 3 position of the handle 4 (see...). Figure 1 , Figure 2 , Figure 3 ).
[0006] The base 1 is made of 40mm thick steel plate, with dimensions of 1500*1500mm (length*width); the upright cylinder 2 is made of 300mm diameter round tube, 600mm long, with a hole running through its middle. The hole dimensions are 80*10mm (length*width); the stop bar 3 is made of 30mm diameter round steel, 600mm long; the handle 4 is made of 40mm diameter round tube, 1200mm long; the support plate 5 is made of 20mm thick steel plate, with dimensions of 500*300mm (length*width); the sliding roller 6 is a pre-made bearing with an outer diameter of 200mm and an inner diameter of 100mm; the roller 7 is made of 100mm diameter round tube, 300mm long.
[0007] In use, the flat steel 8 is passed through the hole in the middle of the vertical cylinder 2 of the bending device, and the bending size of the flat steel 8 is adjusted. Then, the operating handle 4 is rotated around the roller 7, so that the stop bar 3 is pressed against the flat steel 8. Under the action of the external force of the stop bar 3, the flat steel 8 gradually bends along the vertical cylinder 2 until the bending arc of the flat steel 8 meets the usage requirements. Figure 4 , Figure 5 , Figure 6 ).
[0008] The advantages of this utility model are that it is easy to assemble, easy to operate, simple and practical, solves the problem of purchasing bending equipment, and also saves labor maintenance costs and reduces construction costs. Attached Figure Description

[0016] Figures 1-6 This is one specific embodiment of the present invention. The present invention will be further described below with reference to the accompanying drawings.
[0017] This utility model includes a base 1, a vertical cylinder 2, a stop bar 3, a handle 4, a support plate 5, a sliding roller 6, and a roller 7, which are used in combination. The vertical cylinder 2 is vertically welded to the base 1; the support plate 5 is welded to the top of the vertical cylinder 2; the sliding roller 6 and the roller 7 form a rolling system, and the sliding roller 6 can rotate around the roller 7; the roller 7 is vertically welded to the top of the support plate 5; the handle 4 is vertically welded to the side of the sliding roller 6; and the stop bar 3 is vertically welded to the lower side of the front 1 / 3 position of the handle 4.
[0018] When in use, pass the flat steel 8 through the hole in the middle of the vertical cylinder 2 of the bending device, and adjust the bending size of the flat steel 8. Then, operate the handle 4 to rotate around the roller 7, so that the stop bar 3 presses against the flat steel 8. Under the action of the external force of the stop bar 3, the flat steel 8 gradually bends along the vertical cylinder 2 until the bending arc of the flat steel 8 meets the usage requirements.
[0019] During steel structure fabrication, an arc bending device was used for the corner bending of guardrail flat steel, achieving good results. This bending device is used in combination: the upright is vertically welded to the base; the support plate is welded to the top of the upright; a sliding roller and a roller shaft form a rolling system, with the sliding roller rotating around the roller shaft; the roller shaft is vertically welded to the top of the support plate; the handle is vertically welded to the side of the sliding roller; and the stop bar is vertically welded to the lower side of the front 1 / 3 of the handle. In use, the flat steel is passed through the hole in the middle of the upright of the bending device, and the bending dimensions are adjusted. Then, the handle is rotated around the roller shaft, causing the stop bar to press against the flat steel. Under the external force of the stop bar, the flat steel gradually bends along the upright until the bending arc meets the requirements. This bending device is simple to assemble, easy to operate, and practical, solving the problem of purchasing bending equipment while also saving on labor maintenance costs and reducing construction costs.
