Description

Technical Field

[0001] The utility model relates to the technical field of steel mesh processing, in particular to a two-station bending machine for steel mesh. Background Art

[0002] Steel mesh cages are widely used in building materials such as ALC panels (autoclaved lightweight concrete panels), primarily serving as the structural framework. Because steel chisels are used to hoist the cage into the mold during pouring, the cages require sockets on both sides.

[0003] In the existing technology, plastic clips are typically fastened to the sides of the steel mesh. These clips are provided with steel bar insertion holes, which serve as connectors to connect the steel mesh into a steel mesh cage. Because the strength of plastic clips is significantly lower than that of steel bars, this can negatively impact the structural strength of the ALC board. Therefore, the applicant proposes to directly bend the steel bars within the steel mesh itself, creating steel bar insertion holes within the bent sections to enhance the structural strength of the ALC board. Currently, there is a need to design equipment for bending these steel bar insertion holes. Utility Model Content

[0046] like Figure 1 As shown, this embodiment provides a two-station bending machine for steel mesh, comprising:

[0047] The first bending station has at least one steel bar bending mechanism provided on the first frame, which is used to bend the steel bars to be bent on both sides of the steel mesh 200 to form a vertical bending section 201; Figure 1 、 Figure 2 As shown, generally, there are two steel bar bending mechanisms;

[0048] The second bending station, such as Figure 1 、 Figure 3 As shown, there is at least one steel bar stamping mechanism mounted on a second frame and a workbench 113 for supporting the steel mesh. Above the workbench is a liftable pressure bar 114 for compressing the steel mesh during the stamping process. The pressure bar is driven by a driver and can be vertically lifted in conjunction with a guide member. The steel bar stamping mechanism is used to stamp the vertical bent section to form a bent portion 202.

[0049] Generally, there are two steel bar punching mechanisms, and the punching directions (or arrangement directions) of the two steel bar punching mechanisms are opposite, and the punched bending parts are in opposite directions. After the two steel mesh sheets are closed up and down and welded to form a steel mesh cage, the two bending parts 202 are arranged relative to each other to form a steel drill socket 203. The structure is as follows Figure 10 shown.

[0050] In order to adjust the distance between the first bending station and the second bending station and adapt to the steel mesh with different transverse steel bar spacing, in this embodiment, at least one of the first frame and the second frame is slidably installed on the base and can slide longitudinally on the base under the action of the driving member. The driving member is recommended to adopt a structure of a spacing adjustment screw rod 100 and a nut. Generally, the first bending station and the second bending station are both slidably installed on the base and are respectively connected to the spacing adjustment screw rod 100 through nuts. The thread directions of the screw rod parts connected to the nuts of the first bending station and the second bending station are opposite.

Each bending station has a steel bar pre-stressing mechanism, a steel bar bending mechanism, etc., wherein the steel bar bending mechanism has a working platform 501, a clamping mechanism and a jacking mechanism, etc. The working platform 501 is fixed on the first frame 500, and the working platform 501 is used to place the steel mesh to be bent.

[0052] like Figure 9 As shown, the steel bar prestressing mechanism includes a prestressing plate 519 and a prestressing drive mechanism 520, wherein the prestressing plate 519 is located above the working platform 501. The lower end surface of the prestressing plate 519 is formed with a guide groove adapted for the transverse steel bars. The upper end of the prestressing plate 519 is connected to the operating end of the prestressing drive mechanism 520 via a connector, and the prestressing drive mechanism 520 is mounted and fixed on the first frame 500. In this embodiment, the prestressing drive mechanism 520 can drive the prestressing plate 519 to move up and down. When the prestressing plate 519 moves downward to press the transverse steel bars to be bent on the working platform 501, the guide groove on the lower end surface of the prestressing plate 519 positions the transverse steel bars to be bent on the steel mesh at a designated position on the working platform 501.

[0053] The clamping mechanism includes a bending upper mold fixing plate 511 and a clamping drive mechanism 512, wherein the bending upper mold fixing plate 511 is located above the pre-stressing plate 519, and the lower edge of the bending upper mold fixing plate 511 is provided with a bending portion corresponding to the pre-stressing plate 519, so that the bending upper mold fixing plate 511 can further clamp the transverse steel bars clamped and positioned by the pre-stressing plate 519; the bending upper mold fixing plate 511 is connected to the action end of the clamping drive mechanism 512, and the clamping drive mechanism 512 is fixed on the first frame 500. The clamping drive mechanism 512 can drive the bending upper mold fixing plate 511 to move up and down, and the bending upper mold fixing plate 511 moves downward to clamp the middle section of the transverse steel bars to be bent on the working platform 501.

[0054] like Figure 1 、 Figure 2 as well as Figures 5 to 7 As shown, the jacking mechanism is located below the working platform 501 and has a jacking slide 502, a jacking arm 503 and a bending angle adjustment mechanism.

[0055] There are two lifting slides 502, each corresponding to the bending sections at the ends of the transverse steel bars to be bent. The lifting slides 502 are arranged vertically and are equipped with vertical slide rails I, which are equipped with sliders I. Slider I is connected to the first frame 500 via a slider base, so that the lifting slides 502 can only move vertically under the action of sliders I and vertical slide rails I.

[0056] The lower ends of the two lifting slides 502 are commonly connected to the lifting arm, and a lifting drive mechanism 505 is connected below the middle of the lifting arm. The lifting drive mechanism 505 can drive the two lifting slides 502 to move up and down through the lifting arm.

[0057] The jacking arm 503 is installed in the upper part of the jacking slide 502. The lower end of the jacking arm 503 can be rotatably connected to the middle part of the jacking slide 502 via the rotating shaft 525. The upper end of the jacking arm 503 can be rotatably connected to the V-groove roller 704 via the rotating shaft 525. The upper groove of the V-groove roller 704 is adapted to the steel bar. The V-groove roller 704 is used to contact the steel bar when the jacking mechanism moves upward.

[0058] A bending angle adjustment mechanism is provided in the middle position of the two lifting slides 502. The bending angle adjustment mechanism is connected to the two lifting arms 503 on the two lifting slides 502, and is used to adjust the angle at which the lifting arm 503 rotates around its lower end rotating shaft 525 during the upward movement of the lifting slide 502, thereby adjusting the angle at which the lifting arm 503 and the V-groove roller 704 bend the steel bars.

[0059] The bending angle adjustment mechanism includes a connecting rod seat 506 and a vertical position adjustment mechanism, wherein the connecting rod seat 506 is connected to two connecting rods 507 corresponding to the two lifting arms 503, one end of the connecting rod 507 is connected to the connecting rod seat 506 via a pin shaft, and the other end of the connecting rod 507 is connected to the middle part of the corresponding lifting arm 503 via a pin shaft; the connecting rod seat 506 can be adjusted to a vertical position by the vertical position adjustment mechanism and is fixed on the lower end surface of the working platform 501, and the vertical position of the connecting rod seat 506 is adjusted to achieve the angle of rotation of the lifting arm 503 around its lower end rotating shaft 525 during the upward movement of the lifting slide 502.

[0060] The vertical position adjustment mechanism includes a guide rod 508, a fixed seat 509 and a bushing 510, wherein the guide rod 508 is arranged vertically, and the connecting rod seat 506 is installed on the guide rod 508 through the bushing 510. The upper end of the guide rod 508 is provided with an external thread, and the fixed seat 509 is fixed to the lower end surface of the working platform 501. The fixed seat 509 is provided with a screw hole that is adapted to the external thread on the guide rod 508. The guide rod 508 is threadedly connected to the fixed seat 509. The upper and lower positions of the guide rod 508 are adjusted by rotating the guide rod 508 to cooperate with the screw holes on the fixed seat 509, thereby adjusting the upper and lower positions of the connecting rod seat 506 on the guide rod 508.

[0061] In this embodiment, the bushing 510 is fixed on the guide rod 508, and a limiting ring is formed on the upper end of the bushing 510. The connecting rod seat 506 is sleeved on the bushing 510, and the limiting ring on the upper end of the bushing 510 limits the connecting rod seat 506 from moving upward.

[0062] In this embodiment, a plurality of vertically arranged guide rods 521 are mounted on the connecting rod base 506. A guide member 522 is mounted on a lifting arm 524 below the connecting rod base 506, corresponding to the guide rods 521. The guide rods 521 are provided with guide holes adapted to fit the guide rods 521. The upper ends of the guide rods 521 are connected to the connecting rod base 506, while the lower ends of the guide rods 521 extend downwardly through the guide holes in the guide member 522. In this embodiment, a spring is mounted on the guide rod 521. The upper end of the spring abuts against a retaining ring on the upper portion of the guide rod 521, while the lower end of the spring is supported on the guide member 522.

[0063] In this embodiment, the connecting rod seat 506 is sleeved on the bushing 510, and the two can rotate relative to each other. Under the action of the guide rod 521 and the spring, the connecting rod seat 506 is pressed from bottom to top on the limit ring at the upper end of the bushing 510.

[0064] In this embodiment, the vertical position of the bushing 510 on the guide rod 508 is adjusted by rotating the guide rod 508 and utilizing the threaded connection between the guide rod 508 and the fixed seat 509, thereby adjusting the upper and lower positions of the connecting rod seat 506, and finally achieving the inclination adjustment of the lifting arm 503.

[0065] like Figure 1 、 Figure 4 As shown, the steel bar stamping mechanism has a lifting beam 513 and a stamping groove 515, wherein sliders II are installed at both ends of the lifting beam 513, and the sliders II are installed on the first frame 500 via vertical slide rails II. The middle part of the lifting beam 513 is connected to the action end of the stamping lifting mechanism 514, and the stamping lifting mechanism 514 is fixed on the first frame 500. The stamping lifting mechanism 514 can drive the lifting beam 513 to move up and down.

[0066] The steel bar stamping mechanism is equipped with a stamping slot 515 at each of the two bent sections at each end of the transverse steel bar. These two stamping slots 515 are mounted on the lifting beam 513 for horizontal movement via a horizontal transverse mechanism. In this example, the horizontal transverse mechanism comprises a transverse rail mounted on the lifting beam 513, which is connected to the stamping slots 515 via a transverse slider and a connecting plate. A transverse drive mechanism is located between the two stamping slots 515. This transverse drive mechanism is fixed to the lifting beam 513, with its actuating end connected to the connecting plate. This mechanism drives the stamping slots 515 for horizontal movement along the transverse rail via the connecting plate.

[0067] A stamping die 516 is fixed to one end of the wall of the stamping slot 515, and a stamping punch 517 is installed at the other end of the stamping slot 515. The position of the stamping punch 517 corresponds to the position of the stamping die 516. The stamping punch 517 is connected to the operating end of the stamping drive mechanism 518, and the stamping drive mechanism 518 is fixedly connected to the stamping slot 515. The stamping drive mechanism 518 can drive the stamping punch 517 to move toward or away from the corresponding stamping die 516.

[0068] The steel mesh to be bent enters the bending device longitudinally and is placed on the working platform 501 of the first bending station;

[0069] After the transverse steel bar to be bent is moved to the corresponding position on the working platform 501, the steel bar pre-pressing mechanism is activated to press the transverse steel bar to be bent through the pre-pressing plate 519, so that the transverse steel bar is positioned at the specified position;

[0070] The pressing mechanism moves the upper bending die plate 511 downward to press the transverse steel bars at the designated position on the lower working platform 501. The upper bending die plate 511 presses the middle section of the transverse steel bars, and the unpressed sections at both ends of the transverse steel bars are the subsequent bending sections.

[0071] The jacking drive mechanism 505 drives the jacking slide 502 to move upward, and the jacking slide 502 drives the jacking arm 503 to move upward. Since the middle part of the jacking arm 503 is connected to the connecting rod seat 506 via the connecting rod 507, the jacking arm 503 gradually rotates around the lower end rotation axis 525 during the upward movement of the jacking arm 503, and the upper end of the jacking arm 503 gradually tilts toward the connecting rod seat 506, and the tilt angle gradually increases;

[0072] During the upward movement of the jacking arm 503, the V-groove roller 704 at its upper end contacts the bending section of the transverse steel bar to bend the bending section, and the bending angle of the bending section gradually increases as the tilt angle of the jacking arm 503 increases;

[0073] After the jacking drive mechanism 505 drives the jacking slide 502 to move up to the specified position, it drives the jacking slide 502 to move downward, and the jacking arm 503 gradually returns to its original position;

[0074] To avoid interference with subsequent stamping operations, after the jacking mechanism is reset, the clamping mechanism is activated to drive the bending upper die fixing plate 511 to move upwards.

[0075] The bending section is bent to a vertical state, forming a 90° angle with the plane of the steel mesh;

[0076] The steel mesh continues to move and enters the workbench of the second bending station. The height of the steel bar stamping mechanism is adjusted so that the steel mesh enters the steel bar stamping mechanism. After the transverse steel bar reaches the predetermined position, the pressure strip is lowered to press the transverse steel bar. The structure of the pressure strip can refer to the bending upper die fixing plate 511. The steel bar stamping mechanism is activated so that the bending sections at both ends of the transverse steel bar on the working platform 501 are located in the stamping groove 515.

[0077] The stamping drive mechanism 518 is activated to drive the stamping punch 517 to move toward the stamping die 516 , thereby stamping a bent portion on the bending section between the stamping punch 517 and the stamping die 516 .

[0078] The above description is only a preferred embodiment of the present invention. For those skilled in the art, various modifications and variations of the present invention are possible. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the scope of protection of the present invention.
