[0003] In the prior art, plastic clips are generally used to fix the two sides of the steel mesh, and steel bar insertion holes are provided on the plastic clips. The plastic clips can also be used as connectors to combine the steel mesh into a steel mesh cage. Since the strength of the plastic clips is much lower than that of the steel bars, it has a certain impact on the structural strength of the ALC board.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features.

[0064] Embodiment 1:

[0065] When casting some ALC panels, a single steel mesh is used for structural reinforcement, and steel bar insertion holes need to be processed on both sides of the single mesh. This embodiment is mainly aimed at bending and forming the steel bar insertion holes of such steel mesh.

[0066] like Figure 1 As shown, this embodiment provides a steel bar insertion hole bending and forming mechanism for a steel mesh, comprising a first support member 100 and two bending assemblies 101. The main function of the first support member 100 is to serve as the installation base of the bending assembly 101. Obviously, the two bending assemblies 101 should be installed on both sides of the steel mesh 200, located on the left and right sides of the first support member 100. Each bending assembly 101 includes a sliding seat 105 and a movable pressing die 106 and a movable backing die 111 slidably arranged on the sliding seat 105. The sliding seats 105 of the two bending assemblies 101 are slidably matched on the first support member 100 through a sliding pair, and each is driven by a driving member. The sliding direction of the sliding seat 105 is the lateral direction of the steel mesh 200. The sliding seats 105 of the two bending assemblies 101 are between the sliding seats 105 of the two bending assemblies 101. The travel channel of the steel mesh 200 is provided. Under the action of the driving member, the sliding seats 105 of the two bending assemblies 101 can be relatively close or separated, and can adapt to steel meshes 200 of different widths.

[0067] like Figure 2 As shown, in this embodiment, a transverse through hole is provided on the sliding seat 105, and the movable backing mold 111 is movably installed in the transverse through hole. A driving member is provided on the outer wall of the sliding seat 105, and the movable backing mold 111 can slide in the transverse direction of the steel mesh 200 under the action of the driving member. A guide block 107 with a longitudinal guide groove and a longitudinal through hole is provided in the sliding seat 105, and the movable pressing mold 106 is movably installed in the longitudinal guide groove. One end of the movable pressing mold 106 is connected to the driving member, and the other end faces the side where the movable backing mold 111 is located. The movable pressing mold 106 can slide in the longitudinal direction of the steel mesh 200 under the action of the driving member. The vertical bending section 201 of the steel mesh 200 can be allowed to enter between the guide block 107 and the movable backing mold 111. When the movable pressing die 106 is pushed out, the vertical bending section 201 of the steel mesh 200 is pressed against the movable backing mold 111, so that the bending section 201 is bent along the forming surface of the movable backing mold 111 to form a steel bar insertion hole 203.

[0068] Specifically, Figure 3 As shown, the molding surface of the movable mold 111 includes a primary bending molding surface 103 and a secondary bending molding surface 104, and the primary bending molding surface 103 is relatively closer to the transverse through hole;

[0069] The lower side of one end of the movable die 106 facing the movable backing die 111 is provided with a primary die pressing opening 109 corresponding to the primary bending forming surface 103 and a secondary die pressing opening 110 corresponding to the secondary bending forming surface 104. The primary die pressing opening 109 is located above the secondary die pressing opening 110.

[0070] The bending section 201 is first pressed by the primary die pressing port 109 on the primary bending forming surface 103 for bending, and then the driving member drives the movable backing die 111 to retract, so that the secondary die pressing port 110 is opposite to the movable die 106, and then the bending section 201 that has been bent once is pressed by the secondary die pressing port 110 on the secondary bending forming surface 104 for bending, forming a steel drill socket, and the plane where the steel drill socket is located is basically perpendicular to the transverse steel bar.

[0071] A spring rod 108 is arranged in the longitudinal through hole of the guide block 107 , and the spring rod 108 is connected to the movable die 106 and can be longitudinally extended and retracted. When the movable die 106 moves toward the movable backing die 111 , the spring rod 108 pre-presses the bending section 201 onto the movable backing die 111 .

[0072] The sliding seat 105 and the guide block 107 are provided with a receiving groove 102 for receiving the longitudinal steel bars, so as to prevent the outermost longitudinal steel bars from being blocked, thereby allowing the bending section 201 to enter between the guide block 107 and the movable backing plate 111 .

[0073] In this embodiment, it is recommended to use the cylinder 115 as the driving member of the sliding seat 105.

[0074] When the bending operation is not performed, the distance between the two bending components 101 is relatively far. When the to-be-bent sections 201 on both sides of the steel mesh 200 reach the predetermined position, the distance between the two bending components 101 becomes closer, and the vertical bending section 201 of the steel mesh 200 enters between the guide block 107 and the movable support mold 111. The primary bending forming surface 103 of the movable support mold 111 faces the primary molding port 109 of the movable pressure die 106. The movable pressure die 106 is pushed out to bend the upper end of the bending section 201. Then the movable support mold 111 slides to make the secondary bending forming surface 104 face the secondary molding port 110 of the movable pressure die 106. The movable pressure die 106 is pushed out again, and the bending section 201 is bent again on the secondary bending forming surface 104 to form a steel bar socket 203. The structure of the steel bar socket is the same as that of the Fig.14 As shown, during the two bending processes, the spring rod 108 keeps pressing the bending section 201 to reduce the deviation of the bending section 201. Afterwards, the movable pressing die 106 and the movable backing die 111 are reset, and the two bending assemblies 101 are separated again to detach from the steel mesh 200, waiting for the next operation.

[0075] Embodiment 2:

[0076] like Figure 3 As shown, this embodiment provides a bending device, including:

[0078] The second bending station, such as Figure 5 As shown, there are at least one steel bar stamping mechanism arranged on the second frame, at least one bending and forming mechanism as described in Example 1, and a workbench 113 for supporting the steel bar mesh, and a liftable pressure strip 114 is arranged above the workbench for pressing the steel bar mesh during the stamping and bending forming process, and the pressure strip is driven by a driving member and can be lifted vertically in cooperation with a guide member. The steel bar stamping mechanism is used to stamp the vertical bending section to form a bending portion 202.

[0079] Generally, there are two steel bar stamping mechanisms and two bending forming mechanisms, and the stamping directions (or arrangement directions) of the two steel bar stamping mechanisms are opposite, and the directions of the stamped bending parts are opposite, such as Fig.15 As shown, after the two steel mesh sheets are folded up and down and welded to form a steel mesh cage, the two bent portions are arranged opposite to each other to form a steel drill insertion hole 203.

[0094] In this embodiment, the connecting rod seat 506 is sleeved on the bushing 510, and the two can rotate relatively. 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.

[0095] In this embodiment, the guide rod 508 is rotated and the threaded connection between the guide rod 508 and the fixing seat 509 is utilized to adjust the vertical position of the bushing 510 on the guide rod 508, thereby adjusting the up and down position of the connecting rod seat 506, and finally achieving the inclination adjustment of the lifting arm 503.

[0096] like Figure 6 , Figure 8 As shown, the steel bar stamping mechanism has a second support member 513 and a stamping groove 515, wherein sliders II are installed at both ends of the second support member 513, and the slider II is installed on the first frame 500 via a vertical slide rail II. The middle part of the second support member 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 second support member 513 to move up and down.

[0097] The steel bar stamping mechanism is provided with a stamping groove 515 at the two bending sections 201 at both ends of the transverse steel bar, respectively. The two stamping grooves 515 are installed on the second support member 513 so as to be horizontally movable via a horizontal transverse movement mechanism. In this example, the horizontal transverse movement mechanism comprises a transverse slide rail installed on the second support member 513, and the transverse slide rail is connected to the stamping groove 515 via a transverse slider and a connecting plate. A transverse movement driving mechanism is provided between the two stamping grooves 515, and the transverse movement driving mechanism is fixed on the second support member 513. The action end of the transverse movement driving mechanism is connected to the connecting plate, and the transverse movement driving mechanism can drive the stamping groove 515 to move horizontally along the transverse slide rail via the connecting plate.

[0098] A stamping die 516 is fixed at one end of the groove wall of the stamping groove 515, and a stamping punch 517 is installed at the other end of the stamping groove 515. The position of the stamping punch 517 corresponds to the stamping die 516. The stamping punch 517 is connected to the action end of the stamping drive mechanism 518, and the stamping drive mechanism 518 is fixedly connected to the stamping groove 515. The stamping drive mechanism 518 can drive the stamping punch 517 to move toward or away from the corresponding stamping die 516.

[0099] The steel mesh 200 to be bent enters the bending device longitudinally and is placed on the working platform 501 of the first bending station;

[0100] 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;

[0101] The clamping mechanism moves the upper bending die fixing plate 511 downward to clamp the transverse steel bars at the designated position on the lower working platform 501. The upper bending die fixing plate 511 clamps the middle section of the transverse steel bars, and the uncompressed sections at both ends of the transverse steel bars are the subsequent bending sections 201.

[0102] The lifting drive mechanism 505 drives the lifting slide 502 to move upward, and the lifting slide 502 drives the lifting arm 503 to move upward. Since the middle part of the lifting arm 503 is connected to the connecting rod seat 506 via the connecting rod 507, the lifting arm 503 gradually rotates around the lower end rotation axis 525 during the upward movement of the lifting arm 503, and the upper end of the lifting arm 503 gradually tilts toward the connecting rod seat 506 side and the tilt angle gradually increases;

[0103] During the upward movement of the lifting arm 503, the V-groove roller 704 at the upper end thereof contacts the bending section 201 of the transverse steel bar to bend the bending section 201, and the bending angle of the bending section 201 gradually increases as the inclination angle of the lifting arm 503 increases;

[0104] After the lifting drive mechanism 505 drives the lifting slide 502 to move upward to the specified position, it drives the lifting slide 502 to move downward, and the lifting arm 503 gradually returns to its original position;

[0105] In order 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 upward;

[0106] The bending section 201 is bent to a vertical state, and substantially forms an angle of 90° with the plane where the steel mesh 200 is located;

[0107] The steel mesh continues to move and enters the second bending station. After reaching the predetermined position, the pressure strip 114 descends to press the transverse steel bars on the workbench 113. The structure of the pressure strip 114 can refer to the bending upper mold fixing plate 511.

[0108] At this time, if a single steel mesh needs to be processed, the height of the steel drill hole bending and forming mechanism is adjusted so that the steel mesh 200 enters the steel drill hole bending and forming mechanism, and the two bending components bend the bending section;

[0109] If the steel mesh required for the steel mesh cage needs to be processed, adjust the height of the steel stamping mechanism so that the steel mesh enters the steel stamping mechanism; the steel stamping mechanism is activated so that the bending sections 201 at both ends of the transverse steel bars enter the stamping groove 515; the stamping drive mechanism 518 is activated to drive the stamping punch 517 to move toward the stamping die 516, thereby stamping out a bending portion on the bending section 201 between the stamping punch 517 and the stamping die 516.

[0110] The above is only a preferred embodiment of the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
