Description

Technical Field

[0001] The utility model belongs to the field of steel material processing, in particular to a bending device for steel structure processing. Background Art

[0002] In the process of steel structure processing, due to the variety of steel structure models, especially some round tube steel structure shapes are also very changeable, so the bending operation is also very frequent, the existing round tube steel bending mostly use manual bender.

[0003] A manual pipe bender disclosed in Chinese patent CN219052537U optimizes the complex mold part of the pipe bender and decomposes it into three parts: a bench vise clamp, a guide groove block, and a positioning wheel block. The three parts are machined separately and then welded together, which is convenient for processing and manufacturing. The structure is simple and the setting is reasonable, which greatly reduces the manufacturing cost. In order to prevent the supporting shaft at the center of the rotating wheel block from being squeezed and deformed, an upper limit plate is added between the two supporting shafts of the positioning wheel block and the rotating wheel block to effectively strengthen the local strength. The bottom of the positioning wheel block and the rotating wheel block both adopt a double nut locking structure, which can adjust the gap and effectively prevent the long handle and the positioning wheel block from getting stuck.

[0004] Currently, most round steel tubes are bent using manual bending machines, but the manual device requires human power. The thickness of round steel tubes varies, and it is difficult to bend them completely by manpower alone. Some hydraulic tube bending machines cannot be adjusted, so the degree of bending of the round tube depends entirely on manual experience. Utility Model Content

[0005] To solve the above problems, the utility model adopts the following technical solutions.

[0006] A bending device for steel structure processing comprises a bending disk, a connecting shaft passing through the center of the bending disk, a first connecting rod and a second connecting rod being sleeved on both ends of the connecting shaft in sequence from the outside to the inside, a first clamping block being installed in the first connecting rod, a connecting block being integrally connected to the front surface of the bending disk, a second clamping block being connected to the connecting block by a pin shaft, a pin joint being connected to the end of the second connecting rod, a telescopic rod being connected by the pin joint, a round tube steel being inserted between the first clamping block, the second clamping block and the bending disk, the first connecting rod being kept fixed, the second connecting rod being driven to rotate by the telescopic rod, the bending disk being driven to rotate synchronously by the second connecting rod, and the round tube steel being constrained to be bent according to the curvature of the outer contour of the bending disk by the second clamping block installed on the front surface of the bending disk.

[0007] A plurality of through holes are equidistantly provided on the side surfaces of the first connecting rod and the second connecting rod, the number of through holes on the first connecting rod is greater than the number of through holes on the second connecting rod, a first pin is passed through the first clamping block assembled in the first connecting rod, and both ends of the first pin are inserted into the through holes on the side surfaces of the first connecting rod so that the first clamping block is assembled on the first connecting rod.

[0008] A second pin is inserted into a through hole formed on the side of the second connecting rod, and the second pin penetrates the bending disk so that the bending disk and the second connecting rod form a whole.

[0009] The bending disk is an incomplete disc-shaped structure, and a plurality of insertion holes are arranged on the bending disk in a surrounding manner and at equal intervals, and the second pins are inserted into the insertion holes on the bending disk.

[0010] The bending disk has a certain thickness, and a groove is centrally provided along the thickness of the bending disk, wherein the cross section of the groove is a semicircular structure.

[0011] A support rod is fixedly connected to the end of the first connecting rod by a pair of bolt groups, and a fixing block is pin-connected to the end of the telescopic rod and connected to the support rod.

[0012] A dividing plate is assembled on one side of the first connecting rod, the front end of the dividing plate is a circular structure, and an angle value is engraved on the inner side of the dividing plate.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] (1) The present application utilizes a telescopic rod for driving, so that the bending equipment can perform automatic bending, thereby having sufficient power when bending some thick round tube steels, and being able to perform one-time bending and forming, thereby avoiding the disadvantages of traditional manual bending, which is caused by insufficient power, resulting in multiple force bending of the round tube, causing the prestress inside the round tube to change, resulting in a decrease in the overall strength of the bend and an increase in fatigue.

[0015] (2) Furthermore, the present application is capable of adjusting the bending curvature of a circular tube when bending the circular tube. Specifically, the bending disk and the first connecting rod and the second connecting rod in the present application are all provided with through holes. The first clamping block on the first connecting rod for constraining the circular tube can be fixed in different circular holes on the first connecting rod by a pin, so as to adjust the distance between the first clamping block and the end of the bending disk, so as to adapt to circular tubes with different diameters. The adjustment here can also enable the present bending device to bend a bar steel structure. Furthermore, the bending disk can be rotated on the second connecting rod through the connecting shaft, and the bending disk is fixed by a second pin provided on the second connecting rod, so that when the bending disk is driven by the telescopic rod, the length of the rotation motion trajectory is different, so as to change the arc angle of the circular tube when bending, so that when the present application is automatically bent, it can synchronously perform different curvatures on the steel structure bearing.
