Description

Technical Field

[0001] The present invention relates to a bending device, in particular to a bending device for steel structure processing, belonging to the technical field of steel structure processing. Background Art

[0002] Cable bridges are a type of steel structure, a supporting structure commonly used in construction and industry. They are primarily used to support the installation and routing of various pipelines and equipment, including power distribution cables, signal cables, and control cables. Cable bridges are typically made of steel and offer advantages such as protecting cables from environmental damage, facilitating management and maintenance, and extending cable life. Cable bridge hangers are a crucial component of the cable bridge system. They are steel structural connectors used during cable bridge installation. Their primary function is to suspend the cable bridge from a ceiling or bracket, ensuring its stability and safety. They offer a strong load-bearing capacity.

[0003] The Chinese patent titled "A Bending Equipment and Method for the Production of Steel Structure Metal Components" (patent number ZL202411418813.2) discloses a bending equipment technology. However, although the equipment has the characteristics of being convenient for bending heads and bending tables, and existing bridge hangers all use similar bending equipment for bending production, this type of equipment can only perform one bending operation at a time, the operating efficiency is low, and manual adjustment of the bending position of the workpiece is required, which is inconvenient to use.

[0004] The Chinese patent named "A Steel Structure Bending Device" (patent number ZL202411295755.9) discloses a bending device technology, in which the steel structure to be bent is transported to a specified position through a loading mechanism, and the side pressure plate performs unidirectional or bidirectional side bending on the steel structure. Under the joint action of the pressure head and the bending die, the end face of the steel structure is accurately bent to a preset angle and shape. However, although the device can achieve multi-point bending of steel structures in one operation, the position of its side pressure plate is relatively fixed. When performing unidirectional or bidirectional lateral bending, it can only bend one place of the workpiece, and cannot perform unidirectional or bidirectional lateral bending continuously, and cannot meet the processing requirements of workpieces with many and symmetrical bending points, such as bridge hangers and similar steel structure workpieces. For this reason, a bending device for steel structure processing is proposed. Summary of the Invention

[0032] In one embodiment, a loading and unloading assembly 8 is installed on one side of the pressure plate 204, and the loading and unloading assembly 8 includes a positioning mechanism 801 and two unloading mechanisms 802; Among them, the two unloading mechanisms 802 and the positioning mechanism 801 are both installed on one side of the pressure plate 204. The positioning mechanism 801 is used to position and limit the workpiece, and the unloading mechanism 802 is used to provide thrust to one side of the workpiece so that it always fits with one side of the movable pressure plate 202.

The third spring 823 is compressed by the ejector rod 821, so that the third spring 823 cooperates with the ejector rod 821 to provide a continuous pushing force for one side of the hanging code blank 93, so that one side of the hanging code blank 93 is always attached to one side of the movable pressing plate 202, the second spring 814 is compressed by the positioning pin 811 being pressed, when the pin hole 94 on the hanging code blank 93 moves to the positioning pin 811, the positioning pin 811 is inserted into the pin hole 94 by the second spring 814 being compressed to push the push plate 812 to drive the positioning pin 811, so as to position and limit the hanging code blank 93. The length of the positioning pin 811 and the ejector rod 821 is controlled to ensure that the ejector rod 821 pushes the hanging code blank 93 to be separated from the positioning pin 811.

[0033] In one embodiment, one side of the C-shaped support 301 is symmetrically fixedly connected to two triangular supports 91, and the bottoms of the two triangular supports 91 are installed on the upper surface of the support frame 103.

[0034] The sliding groove 92 provides a moving space for the second hydraulic cylinder 503, and the triangular support 91 provides support for one side of the C-shaped support 301 to improve its pressure bearing performance.

[0035] In operation, first, the pin hole 94 is machined in the middle of the hanging code blank 93 by using the punching equipment, then the hanging code blank 93 is inserted between the two clamping frames 402 and the movable pressing plate 202 and the pressure bearing plate 204, the hanging code blank 93 is sequentially pressed against the ejector rod 821 and the positioning pin 811, the third spring 823 is compressed by the ejector rod 821 being pressed, so that the third spring 823 cooperates with the ejector rod 821 to provide a continuous pushing force for one side of the hanging code blank 93, so that one side of the hanging code blank 93 is always attached to one side of the movable pressing plate 202, the second spring 814 is compressed by the positioning pin 811 being pressed, when the pin hole 94 on the hanging code blank 93 moves to the positioning pin 811, the positioning pin 811 is inserted into the pin hole 94 by the second spring 814 being compressed to push the push plate 812 to drive the positioning pin 811, so as to position and limit the hanging code blank 93, thereby completing the feeding operation of the hanging code blank 93.

[0036] When the loading operation of the hanging code blank 93 is completed, the piston rod of the first hydraulic cylinder 201 drives the connecting frame 203 to move, and the moving connecting frame 203 drives the movable pressure plate 202 to move, and the moving movable pressure plate 202 drives the hanging code blank 93 to fit with the pressure plate 204 so as to clamp and fix it, and then the output block of the rodless cylinder 701 is used to drive the base 502 to move, and the moving base 502 cooperates with the guide frame 501 to drive the bilateral bending assembly 4 to move along the X-axis direction as a whole, that is, Figure 1 In the middle, the hanging code blank 93 is in the long direction. When the double-sided bending component 4 moves to the specified position, the output shaft of the reduction motor 451 drives the gear disc 452 to rotate, and the rotating gear disc 452 uses the tooth pattern to drive the turntable seat 403 to rotate. The rotating turntable seat 403 drives the bending pressure rod 404 to squeeze one side of the hanging code blank 93, so as to cooperate with the clamping frame 402 to perform a bending operation on both sides of the hanging code blank 93. When the bridge hanging code is processed, the bending angle can be 30°. After the bending operation on both sides is completed, the turntable drive mechanism 405 drives the turntable seat 403 to drive the bending pressure rod 404 to reset, and then the output block of the rodless cylinder 701 drives the double-sided bending component 4 as a whole to continue to move along the X-axis direction, so as to move the double-sided bending component 4 to the second bending point, and then repeat the operation to perform a secondary bending process on both sides of the hanging code blank 93. When the bridge hanging code is processed, the second bending angle can be 60°, thereby completing the continuous bending operation on both sides of the hanging code blank 93.

[0037] The piston rod of the second hydraulic cylinder 503 drives the supporting platform 401 to move as a whole, and the moving supporting platform 401 drives the clamping frame 402 and the bending pressure rod 404 to slide into the guide frame 501, so that the clamping frame 402 is separated from the hanging code blank 93 to avoid interference with subsequent bending or blanking operations.

[0038] When it is necessary to bend the hanging code blank 93 after the secondary bending by 90°, the output shaft of the driving motor 602 drives the screw rod 603 to rotate, and the rotating screw rod 603 drives the slider 604 to move by the thread, and the moving slider 604 drives the mounting frame 205 to move along the Y axis, that is, the axial direction of the screw rod 603. The moving mounting frame 205 cooperates with the pressure plate 204 and the movable pressure plate 202 to drive the hanging code blank 93 to move. The moving hanging code blank 93 squeezes one side of the two pressure rollers 302, so that it rotates under the action of pressure, and drives the first spring 305 to stretch, so as to utilize the pressure between the movable pressure plate 202 and the pressure roller 302 to cooperate with the shaping groove 303 to perform a 90° bending operation on the hanging code blank 93, so that the bent parts on both sides of the hanging code blank 93 overlap to form a bridge hanging code workpiece. Figure 10 shown.

[0039] When it is necessary to unload the bridge frame hanging code workpiece, the piston rod of the first hydraulic cylinder 201 pushes the connecting frame 203 to drive the movable pressure plate 202 to move, so as to release the clamping of the bridge frame hanging code workpiece, and then the compressed third spring 823 drives the push rod 821 to move, so that the push rod 821 can be used to push the bridge frame hanging code workpiece to fit with the movable pressure plate 202, so that the positioning pin 811 slides out of the pin hole 94, so as to unload the bridge frame hanging code workpiece after processing.

[0040] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto.
