Description

Technical Field

[0001] This utility model relates to the field of steel mesh welding technology, and in particular to a wire threading mechanism and a transverse bar feeding device. Background Technology

[0002] The existing steel mesh welding production line is equipped with two sets of steel bar feeding devices. The steel bar feeding device includes a wire threading tube for fixing the transverse bars and two crossbeams that can rotate relative to each other. The wire threading tube is located in front of the electrode. Each crossbeam is equipped with a clamping claw. The relative rotation of the crossbeams can cause the clamping claws to rotate relative to each other, thereby clamping or releasing the transverse bars in the wire threading tube. The wire threading tube includes a movable upper tube and a movable lower tube. The movable upper tube is fixed on the electrode seat, and the movable lower tube is fixed on a beam. The movable lower tube completes the opening and closing action under the power of the cylinder to cooperate with the feeding of the transverse bars.

[0003] In the aforementioned prior art, the threading tube is suitable for horizontal ribs of fixed size. When used to fix thicker horizontal ribs, the clamping effect is poor. When using thinner horizontal ribs, the horizontal ribs will jump inside the threading tube. Both of these will affect the material dropping effect, resulting in poor material dropping effect.

[0016] The material feeding mechanism is provided in two sets, one above the other. Each set of the material feeding mechanism includes a material feeding drive component and a gripper located at the output end of the material feeding drive component.

[0036] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0037] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0038] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0039] In the description of this embodiment, the terms "upper," "lower," "left," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0040] like Figures 1 to 6As shown, this application provides a wire threading mechanism, which includes a wire threading assembly 1 and a movable drive assembly 2. Multiple wire threading assemblies 1 are arranged at intervals in the horizontal direction. The wire threading assembly 1 includes a wire threading tube, which includes a fixed half tube 11 and a movable half tube 12. The fixed half tube 11 has a through hole. A tube cap 13 is provided on the side of the fixed half tube 11 away from the movable half tube 12 to block the through hole. A first elastic element 14 is provided on the tube cap 13. A stop block 15 is provided on the first elastic element 14. The stop block 15 extends out of the through hole to clamp the transverse rib with the movable half tube 12. The output end of the movable drive assembly 2 is connected to the movable half tubes 12 in multiple sets of wire threading assemblies 1 to drive the movable half tubes 12 to move closer to or away from the fixed half tubes 11.

[0041] With the above structure, when the horizontal rib is placed between the fixed half tube 11 and the movable half tube 12, the abutment block 15 can squeeze the first elastic member 14 according to the diameter of the horizontal rib, and then the restoring force of the first elastic member 14 will react on the horizontal rib, so that the horizontal rib is stably clamped between the first elastic member 14 and the movable half tube 12. It can adapt to the size of the horizontal rib to improve the material dropping effect.

[0042] In some embodiments, the threading tube mechanism includes a threading tube seat 3, a fixed half-tube 11 fixed to the threading tube seat 3, and a movable half-tube 12 hinged to the threading tube seat 3. The fixed half-tube 11 has two through holes spaced apart along the length of the threading tube. Each through hole corresponds to a first elastic element 14 and a stop block 15, thereby further ensuring the stability of the transverse rib. Furthermore, each stop block 15 corresponds to multiple first elastic elements 14, thereby ensuring the stop force. Exemplarily, the first elastic element 14 may be, but is not limited to, a spring.

[0043] In some embodiments, the side of the abutment block 15 opposite to the first elastic member 14 is provided with a recessed groove, which is provided along the length direction of the wire threading tube, so that the transverse rib portion is embedded in the recessed groove, thereby further improving stability.

[0044] like Figure 3 As shown, in some embodiments, the end of the abutment block 15 facing the wire-threading tube is provided with a guide slope 16. The guide slope 16 gradually moves away from the first elastic member 14 from the inlet end of the wire-threading tube near the transverse rib. Thus, when the transverse rib enters the wire-threading tube, the end of the transverse rib abuts against the guide slope 16, causing the abutment block 15 to move towards the first elastic member 14, facilitating the insertion of the transverse rib.

[0045] In some embodiments, the opening of the threading tube facing the guide slope 16 is a flared opening, that is, the inlet end of the threading tube for the transverse rib to pass through is a flared opening. The aforementioned flared opening can provide partial guidance for the insertion of the transverse rib, making it easier for it to be inserted into the threading tube.

[0046] like Figure 2 and Figure 3 As shown, in some embodiments, multiple threading tube assemblies 1 arranged at intervals along the horizontal direction are defined as a group. Two groups of threading tube assemblies 1 are symmetrically arranged at intervals between the upper and lower parts. The fixed half tube 11 located below is also fixed on the threading tube seat 3. By setting two groups of threading tube assemblies 1, the threading efficiency is improved, thereby improving the processing efficiency and avoiding waiting for the threading tube.

[0047] like Figure 1 and Figure 4 As shown, in some embodiments, for ease of driving, two movable drive components 2 are also provided, corresponding to the upper and lower sets of wire-threading tube components 1. The movable half-tubes 12 of the two sets of wire-threading tube components 1 are respectively connected to the output ends of the two movable drive components 2 through the rotating rod assembly 23, thereby driving the movable half-tubes 12 to move. In the current embodiment, the movable drive component 2 includes a movable drive member 21 and a first rotating shaft 22. The movable drive member 21 is connected to the first rotating shaft 22, and the first rotating shaft 22 is rotatably mounted on the frame 4. The rotating rod assembly 23 includes a connecting rod sleeve 235, which is mounted on the first rotating shaft 22 through a first eccentric sleeve 231. A guide rod sleeve 232 is fixed on the connecting rod sleeve 235, and a second elastic member 234 is provided inside the guide rod sleeve 232. The guide rod 233 extends and retracts in the guide rod sleeve 232 under the action of the second elastic member 234. The end of the guide rod 233 away from the second elastic member 234 is connected to the movable half-tube 12, thereby driving the movable half-tube 12 to move closer to or away from the fixed half-tube 11. The second elastic element 234 can act as a buffer, extending its service life. For example, the second elastic element 234 is a spring.

[0048] like Figures 4 to 6 As shown, this application also provides a transverse rib blanking device, which includes a frame 4, a blanking mechanism 5 and the aforementioned wire threading mechanism. The wire threading mechanism is disposed on the frame 4 to clamp the transverse rib through the wire threading tube. The blanking mechanism 5 is arranged in two sets, one above the other. Both sets of blanking mechanisms 5 include a blanking drive component 51 and a gripper 52 disposed at the output end of the blanking drive component 51. The blanking drive component 51 can drive the two grippers 52 respectively to transport the transverse ribs in the two wire threading tubes to the electrode.

[0049] With the above structure, on the one hand, the stability of the transverse ribs can be ensured by the abutment block 15 on the wire threading tube, thereby improving the stability of the material dropping; on the other hand, each gripper 52 is connected to a material dropping drive component 51, so that the transverse ribs in the upper and lower wire threading tubes can be fed into the material dropping separately, thereby improving the material dropping efficiency and thus improving the efficiency of the process.

[0050] In some embodiments, the clamping end of the gripper 52 is provided with a groove 53, into which the transverse rib can be embedded. To facilitate normal material feeding, a guide plate 6 is also provided on the wire threading tube seat 3. The upper and lower surfaces of the guide plate 6 are each provided with a guide surface. The two guide surfaces gradually approach each other from near the wire threading tube seat 3 towards away from it, so that one of the grooves 53 engages with the guide surface, transferring the transverse rib within the groove 53 to the electrode for welding. In other words, this structure allows for multiple material feeding methods: one is that the upper gripper 52 engages with the guide surface on the upper surface of the guide plate 6 to transfer the transverse rib from the upper wire threading tube; another is that the lower gripper 52 engages with the guide surface on the lower surface of the guide plate 6 to transfer the transverse rib from the lower wire threading tube; or the upper and lower grippers 52 together clamp either the transverse rib in the upper or lower wire threading tube for feeding (e.g., ...). Figure 6 (as shown); thus, the material cutting can be selected according to different situations.

[0051] like Figure 4 As shown, in some embodiments, each set of feeding mechanisms 5 is provided with multiple grippers 52, which are distributed along the direction of the transverse ribs to match the length of the transverse ribs.

[0052] It should be noted that, since the gripper 52 with a groove 53 is used, the gripper 52 needs to be able to lift, move horizontally and vertically during the unloading process. In the current embodiment, the unloading drive assembly 51 includes an unloading drive component 511 and a second rotating shaft 513. The motor drives the second rotating shaft 513 to rotate, and the gripper 52 is connected to the second rotating shaft 513 through a connecting rod assembly 512, thereby driving the gripper 52 to lift, move horizontally and vertically.

[0053] Specifically, each linkage assembly 512 includes a first linkage 5121, a second linkage 5122, and two third linkages 5123. The first end of the first linkage 5121 is hinged to the frame 4, and the second end of the first linkage 5121 is hinged to the first end of the second linkage 5122. The gripper 52 is connected to the second end of the second linkage 5122. The first ends of the two third linkages 5123 are rotatably connected to the second rotating shaft 513 through the second eccentric sleeve 5124, and the second ends of the two third linkages 5123 are respectively hinged to the first linkage 5121 and the second linkage 5122. Thus, the linkage assembly 512 drives the gripper 52 to lift and move horizontally, thereby performing the material unloading operation.

[0054] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
