Description

Technical Field

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

[0002] A steel structure is a structure composed of steel materials and is one of the main building structure types. This structure is mainly composed of steel beams, steel columns, steel trusses and other components made of sections and steel plates, and the components are usually connected by welds, bolts or rivets.

[0003] The characteristics of steel structures include: high strength and light weight: The strength of steel is very high. Compared with concrete and wood, the ratio of its density to yield strength is relatively low. Therefore, under the same stress conditions, the cross-section of the components of the steel structure is small, the self-weight is light, and it is convenient for transportation and installation. Good plasticity and uniform material: The steel structure has a very good seismic resistance effect, the material is uniform, and the reliability is high. High degree of mechanization: The steel structure is convenient for manufacturing in the factory and assembling on the construction site, with high production efficiency and short construction period, and it is a structure with a very high degree of industrialization. Good airtightness: The welded structure can be completely sealed, so the built building is strong and has good heat preservation effect.

[0004] Bending equipment is used in the production of steel structures. Specifically, a steel structure bending machine is an efficient large-scale bending equipment.

Application No.: CN202220739771.2 discloses a bending device for steel structure production and processing. The steel pipe is clamped by a fixed clamp and a movable clamp, and in cooperation with a lifting device, the pressure roller is driven to contact the steel pipe and bend the steel pipe, reducing costs and improving the practicability of the device.

[0026] The adjustment assembly 3 includes an adjustment frame 31 arranged on the left side of the base 1, a sliding frame 32 is provided on the top of the adjustment frame 31, a sliding rod 33 is provided on the inner side of the sliding frame 32, which can slide left and right along its length direction, a fixing plate 34 is provided on the top of the side surface of the sliding rod 33, and a button 35 is provided on the right side of the fixing plate 34.

[0027] By moving the sliding rod 33 left and right on the sliding frame 32, the distance of the steel structure outside the placement plate 39 is limited, and through the setting of the first pointer 36 and the first scale 37, the distance between the left side of the placement plate 39 and the sliding rod 33 can be accurately understood.

[0028] The adjustment assembly 3 further includes a first pointer 36 disposed on the front of the sliding rod 33 , a first scale 37 is disposed on the front of the support frame 21 and behind the first pointer 36 , and a toggle rod 38 is disposed on the front of the bending mold 25 .

[0030] Through the arrangement of the contact block 5 and the toggle rod 38, when the second cylinder 24 is pressed down, the toggle rod 38 moves downward accordingly. When it moves to the top of the contact block 5, the toggle rod 38 continues to move downward and the contact block 5 will be toggled to rotate along its own axis. At this time, the second pointer 4 located on the front of the placement plate 39 will rotate synchronously, making it easier for personnel to understand the bending angle.

[0031] On the circumferential side of the second pointer 4 and inside the placement plate 39, a fixed block 6 is provided.

A pushing plate 27 is threadedly connected to the circumferential side of the rotating lead screw 26 and can move left and right along its length direction. Horizontally arranged below the placement plate 39 on the top of the base 1 is a limiting slide bar 28, and the circumferential side of the limiting slide bar 28 is slidably connected to the inner side of the pushing plate 27.

[0034] Through the rotation of the output end of the driving motor 29 to drive the rotation of the rotating lead screw 26, and then in cooperation with the setting of the limiting slide bar 28 to drive the pushing plate 27 to push leftward, thereby pushing the steel structure placed on the placement plate 39.

[0035] At the bottom of the base 1, a driving motor 29 for driving the rotation of the rotating lead screw 26 is provided, and the output end on the right side of the driving motor 29 is belt-connected to the right end of the rotating lead screw 26.

[0036] The working principle of a bending device for steel structure production and processing provided by the present utility model is as follows:

[0037] The first step: When in use, by moving the sliding rod 33 left and right on the sliding frame 32, the distance of the steel structure outside the placement plate 39 is restricted, and through the setting of the first pointer 36 and the first scale 37, the distance between the left side of the placement plate 39 and the sliding rod 33 can be accurately understood.

[0038] The second step: Place the steel structure part to be bent on the placement plate 39. Through the rotation of the output end of the driving motor 29 to drive the rotation of the rotating lead screw 26, and then in cooperation with the setting of the limiting slide bar 28 to drive the pushing plate 27 to push leftward, thereby pushing the steel structure placed on the placement plate 39. When the left side of the steel structure touches the button 35, the button 35 sends a signal to start the first cylinder 22 and stop the driving motor 29 from rotating.

[0039] Step 3: Use the first cylinder 22 to drive the pressing plate 23 at the bottom to fix the steel structure, and then use the second cylinder 24 to drive the bending mold 25 at the bottom to press down and bend one side of the steel structure. Through the setting of the contact block 5 and the toggle rod 38, when the second cylinder 24 presses down, the toggle rod 38 moves downward accordingly. When it moves to the top of the contact block 5, the toggle rod 38 continues to move downward and the contact block 5 will be toggled to rotate along its own axis. At this time, the second pointer 4 on the front of the placement plate 39 will rotate synchronously, making it easier for personnel to understand the bending angle.

[0041] By moving the sliding rod 33 left and right on the sliding frame 32, the size of the distance of the steel structure outside the placement plate 39 is limited, and through the setting of the first pointer 36 and the first scale 37, the distance between the left side of the placement plate 39 and the sliding rod 33 can be accurately understood. When the left side of the steel structure touches the button 35, the button 35 sends a signal to start the first cylinder 22 and stop the drive motor 29, and to enable the second cylinder 24 to drive the bending mold 25 at its bottom to press down and bend one side of the steel structure. The structure is simple and practical, and the bending position can be adjusted in advance before bending the workpiece, avoiding waste of bent parts and having a good use effect.
