Description

Technical Field

[0001] This invention relates to a bending device, specifically a bending device for steel structure processing, and belongs to the field of steel structure processing technology. Background Technology

[0002] Cable trays are a type of steel structure, commonly used in construction and industrial applications as a support structure. They are primarily used to support the installation and wiring of various pipeline equipment such as power cables, signal cables, and control cables. Cable trays are typically made of steel and offer advantages such as protecting cables from environmental damage, ease of management and maintenance, and extended cable lifespan. Cable tray hangers are an important component of the cable tray system, serving as steel structural connectors used during installation. Their main function is to suspend and fix the cable tray to the ceiling or supports, possessing strong load-bearing capacity to ensure the stability and safety of the cable tray system.

[0003] Chinese patent titled "Bending Equipment and Method for Steel Structure Metal Component Production" (patent number ZL202411418813.2) discloses a bending equipment technology. However, although the equipment is convenient for bending heads and bending tables, and existing cable trays and lifting clamps all use similar bending equipment for bending production, this type of equipment can only perform one bending operation at a time, resulting in low operating efficiency. Furthermore, it requires manual adjustment of the workpiece bending position, making it inconvenient to use.

[0004] Chinese patent titled "A Steel Structure Bending Device" (patent number ZL202411295755.9) discloses a bending device technology. A feeding mechanism transports the steel structure to be bent to a designated position, and a side pressure plate performs unidirectional or bidirectional lateral bending on the steel structure. Under the combined action of the pressure head and bending die, the end face of the steel structure is precisely bent to a preset angle and shape. However, although this device can achieve multi-point bending of the steel structure 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 point of the workpiece and cannot continuously perform unidirectional or bidirectional lateral bending. It cannot meet the processing needs of workpieces with many and symmetrical bending points, such as cable trays and similar steel structure workpieces. Therefore, a bending device for steel structure processing is proposed. Summary of the Invention

[0031] The embodiments of the present invention have the following advantages due to the adoption of the above technical solutions:

[0032] I. This invention places the hanging bracket blank to be processed into two clamping frames and a clamping plate mechanism. Then, the clamping plate mechanism clamps and fixes the middle part of the hanging bracket blank. Then, the double-sided bending drive mechanism drives the lifting mechanism to move the double-sided bending assembly to a designated position. Then, the turntable drive mechanism drives the turntable base to move the bending pressure rod. The moving bending pressure rod, together with the clamping frames, performs double-sided synchronous bending of the hanging bracket blank. After one bending operation is completed, the double-sided bending drive mechanism can drive the double-sided bending assembly to continue moving, so that the double-sided bending assembly can perform continuous bending of the hanging bracket blank, which can meet the processing needs of workpieces with many bending points and eliminate the need to repeatedly adjust the position of the hanging bracket blank, thus improving processing efficiency.

The two bending auxiliary mechanisms limit the two sides of the hanging bracket blank and cooperate with the clamping plate mechanism to perform a 90° bending operation on both sides of the hanging bracket blank, so as to process the cable tray hanging bracket in one go and reduce the damage to the workpiece during the 90° bending operation.

[0049] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0050] like Figures 1-10 As shown, this embodiment of the invention provides a bending device for steel structure processing, including a frame assembly 1 and a clamping mechanism 2. The frame assembly 1 includes a central support 101, two side supports 102 and two support frames 103.

[0052] Among them, the double-sided bending drive mechanism 7 is used to drive the lifting mechanism 5 to move the double-sided bending assembly 4 along the X-axis direction, so as to cooperate with the double-sided bending assembly 4 to perform continuous lateral bending operation on the workpiece.

[0053] Among them, the central bending drive mechanism 6 is used to drive the clamping plate mechanism 2 to move along the Y-axis direction;

[0054] Among them, the two double-sided bending components 4 each include a support platform 401, two clamping frames 402, a turntable base 403, a bending pressure bar 404, and a turntable drive mechanism 405;

[0055] Two clamping frames 402 are symmetrically fixedly connected to one side of the upper surface of the support platform 401, the turntable base 403 is rotatably connected to one side of the inner wall of the support platform 401, the bending pressure bar 404 is fixedly connected to the upper surface of the turntable base 403, and the turntable drive mechanism 405 is installed on the upper surface of the support platform 401 to drive the turntable base 403 to reciprocate.

[0056] In one embodiment, the center bending drive mechanism 6 includes a fixed frame 601, a drive motor 602, a lead screw 603, and a slider 604;

[0057] The fixed frame 601 is installed in the middle of the upper surface of the central support 101, the drive motor 602 is installed on one side of the fixed frame 601, one end of the lead screw 603 is rotatably connected to one side of the inner wall of the fixed frame 601, the other end of the lead screw 603 is fixedly connected to the output shaft of the drive motor 602, the inner wall of the slider 604 is threadedly connected to the outer wall of the lead screw 603, and the bottom of the slider 604 is slidably connected to the bottom of the inner wall of the fixed frame 601.

[0058] The output shaft of the drive motor 602 drives the lead screw 603 to rotate. The rotating lead screw 603 drives the slider 604 to move via the thread. The moving slider 604 drives the clamping mechanism 2 to move along the Y-axis.

[0059] In one embodiment, the clamping mechanism 2 includes a first hydraulic cylinder 201, a movable pressure plate 202, a connecting frame 203, a pressure plate 204, and a mounting frame 205;

[0060] The bottom of the mounting bracket 205 is mounted on the upper surface of the slider 604. The first hydraulic cylinder 201 is mounted on the middle of one side of the mounting bracket 205. The pressure plate 204 is fixedly connected to one side of the mounting bracket 205. The movable pressure plate 202 is located on the side of the pressure plate 204 away from the first hydraulic cylinder 201. The connecting bracket 203 is slidably connected between the pressure plate 204 and the mounting bracket 205. One side of the connecting bracket 203 is fixedly connected to one side of the movable pressure plate 202. The other side of the connecting bracket 203 is fixedly connected to the piston rod of the first hydraulic cylinder 201.

[0061] The piston rod of the first hydraulic cylinder 201 drives the connecting frame 203 to move, the moving connecting frame 203 drives the movable pressure plate 202 to move, and the moving movable pressure plate 202 drives the lifting bracket blank 93 to fit against the pressure plate 204.

[0062] In one embodiment, both bending auxiliary mechanisms 3 include a C-shaped bracket 301, a pressure roller 302, a shaping groove 303, two storage grooves 304, and two first springs 305;

[0063] The C-shaped bracket 301 is installed on the upper surface of the support frame 103, the pressure roller 302 is rotatably connected to the inner wall of the C-shaped bracket 301, the shaping groove 303 is opened on one side of the pressure roller 302, the two placement grooves 304 are symmetrically opened on the other side of the outer wall of the pressure roller 302, one end of each of the two first springs 305 is fixedly connected to the inner wall of the placement groove 304, and the other end of each of the two first springs 305 is fixedly connected to one side of the inner wall of the C-shaped bracket 301.

[0064] The pressure roller 302 rotates under pressure, which in turn stretches the first spring 305. This allows the pressure between the movable pressure plate 202 and the pressure roller 302 to work with the shaping groove 303 to perform a 90° bending operation on the hanging bracket blank 93. The rotating pressure roller 302 and the shaping groove 303 can also reduce the damage to the hanging bracket blank 93 during the 90° bending operation.

[0065] In one embodiment, the turntable drive mechanism 405 consists of a geared motor 451 and a gear disc 452;

[0066] Among them, the geared motor 451 is installed on one side of the upper surface of the support platform 401, the gear plate 452 is rotatably connected to one side of the inner wall of the support platform 401, the output shaft of the geared motor 451 is fixedly connected to one end of the gear plate 452, and the outer wall of the gear plate 452 is meshed with the outer wall of the turntable base 403.

[0067] In one embodiment, both lifting mechanisms 5 include a guide frame 501, a base 502, and a second hydraulic cylinder 503;

[0068] The outer wall of the support platform 401 is slidably connected to the inner wall of the guide frame 501, the base 502 is fixedly connected to the bottom of the guide frame 501, the second hydraulic cylinder 503 is installed in the middle of the lower surface of the base 502, and one end of the piston rod of the second hydraulic cylinder 503 passes through the inner wall of the base 502 and is fixedly connected to the bottom of the support platform 401.

[0069] The piston rod of the second hydraulic cylinder 503 drives the entire bearing platform 401 to move. The moving bearing platform 401 causes the clamping frame 402 and the bending pressure rod 404 to slide into the guide frame 501, so that the clamping frame 402 separates from the lifting blank 93.

[0070] In one embodiment, the double-sided bending drive mechanism 7 consists of four rodless cylinders 701;

[0071] Among them, four rodless cylinders 701 are symmetrically installed in pairs on the upper surface of two side supports 102, and the bottom of the base 502 is installed on the upper surface of the output block of the two rodless cylinders 701.

[0072] The base 502 is moved by the output block of the rodless cylinder 701.

[0073] In one embodiment, a loading and unloading assembly 8 is installed on one side of the pressure plate 204. The loading and unloading assembly 8 includes a positioning mechanism 801 and two unloading mechanisms 802.

[0074] Among them, the two unloading mechanisms 802 and the positioning mechanism 801 are all 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 a thrust to one side of the workpiece so that it always fits against one side of the movable pressure plate 202.

[0075] The positioning mechanism 801 consists of a positioning pin 811, a push plate 812, a first sleeve 813, and two second springs 814.

[0076] The first sleeve 813 is fixedly connected to the middle part of the side of the pressure plate 204 away from the movable pressure plate 202. The outer side wall of the push plate 812 is slidably connected to the inner side wall of the first sleeve 813. One end of the positioning pin 811 is fixedly connected to one side of the push plate 812. The outer side wall of the positioning pin 811 is slidably connected to the inner side wall of the pressure plate 204. Two second springs 814 are fixedly connected between the side of the push plate 812 away from the positioning pin 811 and the inner side wall of the first sleeve 813.

[0077] Both unloading mechanisms 802 include a push rod 821, a second sleeve 822, and a third spring 823;

[0078] The second sleeve 822 is fixedly connected to the side of the pressure plate 204 away from the movable pressure plate 202. One side of the outer wall of the push rod 821 is slidably connected to the inner wall of the second sleeve 822, and the other side of the outer wall of the push rod 821 is slidably connected to the inner wall of the pressure plate 204. The third spring 823 is fixedly connected between one end of the push rod 821 and the inner wall of the second sleeve 822. The maximum length of the push rod 821 after passing through the pressure plate 204 is greater than the sum of the maximum length of the positioning pin 811 after passing through the pressure plate 204 and the workpiece thickness.

[0079] The push rod 821 drives the third spring 823 to compress, so that the third spring 823, in conjunction with the push rod 821, provides a continuous thrust to one side of the hanging bracket blank 93, so that one side of the hanging bracket blank 93 is always in contact with one side of the movable pressure plate 202. The pressed positioning pin 811 is compressed by the push plate 812 driving the second spring 814 to compress. When the pin hole 94 on the hanging bracket blank 93 moves to the positioning pin 811, the compressed second spring 814 pushes the push plate 812 to drive the positioning pin 811 to insert into the pin hole 94, so as to position and limit the hanging bracket blank 93.

[0080] By controlling the length of the locating pin 811 and the extension of the push rod 821, it is ensured that the push rod 821 can push the lifting bracket blank 93 to separate from the locating pin 811.

[0081] In one embodiment, one side of the C-shaped bracket 301 is symmetrically fixedly connected to two triangular brackets 91, the bottom of the two triangular brackets 91 is installed on the upper surface of the support frame 103, and a groove 92 is provided in the middle of the upper surface of the side support 102.

[0082] The sliding groove 92 provides movement space for the second hydraulic cylinder 503, and the triangular bracket 91 provides support for one side of the C-shaped bracket 301 to improve its pressure-bearing performance.

[0083] In operation, the present invention works as follows: First, a pin hole 94 is machined in the middle of the hanging bracket blank 93 using a punching device. Then, the hanging bracket blank 93 is moved and inserted between the two clamping frames 402 and between the movable pressure plate 202 and the bearing plate 204. The hanging bracket blank 93 sequentially presses the top rod 821 and the positioning pin 811. The pressed top rod 821 drives the third spring 823 to compress, so that the third spring 823, in conjunction with the top rod 821, provides continuous pressure to one side of the hanging bracket blank 93. The thrust of the pressure plate 202 keeps one side of the hanging bracket blank 93 in contact with the other side of the movable pressure plate 202. The positioning pin 811 is compressed by the push plate 812 driving the second spring 814. When the pin hole 94 on the hanging bracket blank 93 moves to the positioning pin 811, the compressed second spring 814 pushes the push plate 812 to drive the positioning pin 811 to insert into the pin hole 94, so as to position and limit the hanging bracket blank 93, thereby completing the loading operation of the hanging bracket blank 93.

[0084] After the loading operation of the hanging bracket blank 93 is completed, the piston rod of the first hydraulic cylinder 201 drives the connecting frame 203 to move. The moving connecting frame 203 drives the movable pressure plate 202 to move. The moving movable pressure plate 202 causes the hanging bracket blank 93 to fit against the pressure plate 204 for clamping and fixing. Then, the output block of the rodless cylinder 701 drives the base 502 to move. The moving base 502, in conjunction with the guide frame 501, drives the double-sided bending assembly 4 to move along the X-axis direction. Figure 1 In the middle, the direction of the length of the hanging bracket blank 93. After the double-sided bending assembly 4 moves to the designated position, the output shaft of the reduction motor 451 drives the gear disk 452 to rotate. The rotating gear disk 452 drives the turntable base 403 to rotate using its teeth. The rotating turntable base 403 drives the bending pressure rod 404 to press one side of the hanging bracket blank 93, so as to cooperate with the clamping frame 402 to perform a bending operation on both sides of the hanging bracket blank 93. When processing the cable tray hanging bracket, the bending angle can be 30°. After the bending operation on both sides is completed, the turntable drive mechanism 405 drives the turntable base 403 to drive the bending pressure rod 404 to reset. Then, the output block of the rodless cylinder 701 drives the double-sided bending assembly 4 to continue to move along the X-axis, so as to move the double-sided bending assembly 4 to the second bending point. Then, the operation is repeated to perform a second bending process on both sides of the hanging bracket blank 93. When processing the cable tray hanging bracket, the bending angle of the second bending can be 60°, thus completing the continuous bending operation on both sides of the hanging bracket blank 93.

[0085] The piston rod of the second hydraulic cylinder 503 drives the entire support platform 401 to move. The moving support platform 401 causes 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 lifting blank 93, thus avoiding interference with subsequent bending or unloading operations.

[0086] When the secondary bent hanging bracket blank 93 needs to be bent 90°, the output shaft of the drive motor 602 drives the lead screw 603 to rotate. The rotating lead screw 603 drives the slider 604 to move via the thread. The moving slider 604 drives the mounting frame 205 to move along the Y-axis, that is, the axial direction of the lead screw 603. The moving mounting frame 205, together with the bearing plate 204 and the movable pressure plate 202, drives the hanging bracket blank 93 to move.
