[0001] The invention relates to the field of steel cage manufacturing, in particular to a rolling welding machine for a steel cage. Background Art

[0002] At present, the existing seam welding machine includes a base, a seam welding device and a wire release disc device which are assembled on the base and aligned with each other along the length direction of the base. Among them, the vertical wall in the seam welding device, the wire release disc in the wire release disc device and the vertical wall in the wire release disc device are each provided with a channel aligned with each other along the length direction of the base, so that during the seam welding process, the model seat together with a plurality of steel bars arranged together in a ring structure on the model seat slide through the channel; and the wire release disc releases the welding wire to the seam welding device during the self-rotation process, and the seam welding device surrounds the welding wire from the outside and welds it to the ring structure, so as to achieve the purpose of seam welding of the steel cage.

[0003] Since the steel cage rolling welding requires the model seat together with multiple steel bars arranged in a ring structure on the model seat to slide through the channel, when the welding wire on the wire pay-off reel is used up, the operator is required to first move the model seat together with the steel bars arranged in a ring structure out of the channel of the wire pay-off reel, and then the operator can remove the wire pay-off reel; when replacing the wire pay-off reel filled with welding wire, it is also necessary to pass the model seat together with the ring structure into the channel of the wire pay-off reel and slide it to the position where there was no welding wire. Therefore, it causes the defects of long reel changing time, low efficiency, welding wire waste and increased labor.

[0004] Therefore, there is an urgent need for a reinforcing cage rolling welding machine that can overcome one or more of the above-mentioned defects. Summary of the invention

[0009] Preferably, the wire feeding driving mechanism includes a rotating motor, a fixed disk, a meshing tooth ring, and a meshing gear that meshes and drives the meshing tooth ring. The meshing tooth ring is rotatably assembled on the bearing vertical wall. The fixed disk is arranged in a stacked manner with the meshing tooth ring along the first direction, and the fixed disk is also fixedly connected to the meshing tooth ring. The fixed disk is provided with a plurality of clamping structures arranged at intervals along the circumferential direction of the fixed disk. The wire feeding reel is clamped to the fixed disk by means of the clamping structures. The meshing gear is located outside the meshing tooth ring.

[0010] Preferably, a rotating shaft is assembled on the bearing vertical wall beside the outside of the meshing tooth ring. The rotating shaft extends along the first direction.

A central shaft is assembled at the center of the wire spool. One end of the central shaft is clamped with the first safety chuck chuck, and the other end of the central shaft is clamped with the second safety chuck chuck.

[0016] Compared with the prior art, the cage rolling welding machine of the present invention adds a wire feeding reel device beside the middle wire reel device, enabling the middle wire reel device to play the role of an intermediate bridge, responsible for taking in and paying out the welding wire fed by the wire feeding reel device; therefore, during the cage rolling welding process, when the welding wire of the wire feeding reel device runs out and needs to be replaced, it is not necessary to move the steel bars arranged in a circular structure in the welding channel of the rolling welding vertical wall, the middle channel of the middle wire reel, and the docking channel of the middle vertical wall away from the middle channel of the middle wire reel for replacement, thus saving the reel replacement time, improving efficiency, and saving labor; when the used wire feeding reel is larger than the middle wire reel, it can save more reel replacement time, improve efficiency, and reduce the waste of welding wire. In addition, since the middle wire reel is matched with the rolling welding device, its size is restricted by the industry general standard, while the wire feeding reel in the wire feeding reel device added beside the middle wire reel device is not restricted by this, so the wire feeding reel can be designed larger.

[0029] In order to elaborate in detail the technical content and structural features of the present invention, the following further description is made in conjunction with the embodiments and with reference to the drawings.

[0030] Please refer to Figure 1 , Figure 2 , Figure 9 And Figure 10 , the cage rolling welding machine 100 of the first embodiment of the present invention includes a rolling welding device 10, an intermediate wire reel device 20 and a wire feeding reel device 30. The rolling welding device 10 includes a rolling welding vertical wall 11, a rolling welding head 12 and a rolling welding driving mechanism 13. The rolling welding vertical wall 11 is provided with a rolling welding channel 111 extending along a first direction (i.e., the direction indicated by arrow A) therethrough. The rolling welding channel 111 provides a clearance space for a plurality of steel bars 220 arranged in a ring structure on a model base 230 and the sliding movement of the model base 230 along the first direction; the rolling welding head 12 is assembled and connected with the rolling welding driving mechanism 13, and the rolling welding driving mechanism 13 drives the rolling welding head 12 to rotate around the rolling welding channel 111 to meet the movement requirements of the rolling welding head 12 for rolling welding the ring structure formed by a plurality of steel bars 220. Since the rolling welding device 10 is a well-known structure in the art, it will not be described in detail herein.

[0031] Combined with Figures 3 to 8, the intermediate wire spool device 20 includes an intermediate wire spool 21, an intermediate driving mechanism 22 and an intermediate vertical wall 23. The intermediate vertical wall 23 is provided with an alignment channel 231 that penetrates and aligns with the seam welding channel 111 in the first direction. The intermediate wire spool 21 is located between the intermediate vertical wall 23 and the seam welding vertical wall 11 in the first direction, that is, the intermediate wire spool 21 is arranged between the intermediate vertical wall 23 and the seam welding vertical wall 11. The middle of the intermediate wire spool 21 is provided with an intermediate channel 211 that penetrates. The intermediate channel 211 is aligned between the seam welding channel 111 and the alignment channel 231 in the first direction, so that the seam welding channel 111, the intermediate channel 211 and the alignment channel 231 are sequentially butted, so as to meet the need for the annular structure arranged by multiple steel bars 220 to slide through the interiors of the seam welding vertical wall 11, the intermediate wire spool 21 and the intermediate vertical wall 23 in the first direction; the intermediate wire spool 21 is also assembled and connected to the intermediate driving mechanism 22, and the intermediate driving mechanism 22 drives the intermediate wire spool 21 to rotate around the center line of the intermediate channel 211 to meet the power requirement for the rotation of the intermediate wire spool 21; the wire feeding spool device 30 includes a bearing vertical wall 31 located beside the intermediate vertical wall 23 in the second direction (see the direction indicated by arrow B) and a wire feeding spool 32 that is detachably and rotatable on the bearing vertical wall 31, so that the wire feeding spool 32 can not only rotate relative to the bearing vertical wall 31, but also be installed and disassembled relative to the bearing vertical wall 31, so as to meet the need for feeding the welding wire 210 of the wire feeding spool 32 and being replaceable. The welding wire 210 fed by the wire feeding spool 32 bypasses the intermediate wire spool 21 and then enters the seam welding head 12. While the seam welding head 12 winds the welding wire 210 around the annular structure arranged by multiple steel bars 220, it also welds and fixes the welding wire 210 to the annular structure, and the seam welding head 12, the intermediate wire spool 21 and the wire feeding spool 32 rotate in the same direction to ensure the coordinated movement requirements of the intermediate wire spool 21 for one winding and one releasing. Specifically, such as Figure 1 , Figure 2 , Figure 6 , Figure 7 and Figure 8As shown, the wire feeding reel device 32 further includes a wire feeding driving mechanism 33 assembled on the bearing vertical wall 31. The wire feeding driving mechanism 33 is detachably assembled and connected to the wire feeding reel 32 to meet the power requirement for the rotation of the wire feeding reel 32. The speeds of the wire feeding reel 32, the intermediate wire reel 21, and the seam welding head 12 are matched with each other to ensure the reliability of seam welding. It should be noted that the speeds being matched with each other at this time means that the speed of the welding wire 210 fed by the wire feeding reel 32 is preferably equal to the speed of the welding wire 210 received by the intermediate wire reel 31. Of course, it is also allowed to vary within a certain range. Similarly, the seam welding speed of the seam welding head 12 is preferably equal to the speed of the welding wire 210 fed by the intermediate wire reel 31. Of course, it is also allowed to vary within a certain range. Since the seam welding head 12 is driven by the seam welding driving mechanism 13, the intermediate wire reel 21 is driven by the intermediate driving mechanism 22, and the wire feeding reel 32 is driven by the wire feeding driving mechanism 33, it can be achieved through the coordinated control of the seam welding driving mechanism 13, the intermediate driving mechanism 22, and the wire feeding driving mechanism 33. This control can be through circuit design control or PLC logical control, but this is well-known in the art, so it will not be elaborated further. More specifically, as follows:

[0032] As Figure 1 and Figure 2 shown, the wire feeding reel 32 is aligned with the intermediate wire reel 21 along the second direction to ensure the smoothness and coordination of wire feeding by the wire feeding reel 32 and wire receiving by the intermediate wire reel 21. Specifically, in Figures 6 to 8 , the wire feeding driving mechanism 33 includes a rotating motor 331, a fixed disk 332, a meshing tooth ring 333, and a meshing gear 334 that meshes with the meshing tooth ring 333 for transmission. The meshing tooth ring 333 is rotatably assembled on the bearing vertical wall 31, and the bearing vertical wall 31 provides support and an assembly location for the meshing tooth ring 333. The fixed disk 332 is arranged in a stacked manner with the meshing tooth ring 333 along the first direction, and the fixed disk 332 is also fixedly connected to the meshing tooth ring 333 so that the fixed disk 332 and the meshing tooth ring 333 are integrated and rotate together. Three clamping structures 3321 are arranged on the fixed disk 332 at intervals along the circumferential direction of the fixed disk 332. Of course, according to actual needs, the number of the clamping structures 3321 can also be two or four, etc., so it is not limited to what is shown in the drawings. The wire feeding reel 32 is clamped to the fixed disk 332 by means of the clamping structures 3321 to facilitate the installation and removal operation of the wire feeding reel 32. The meshing gear 334 is located outside the meshing tooth ring 333. The rotating motor 331 is installed on the bearing vertical wall 31, and the bearing vertical wall 31 provides support and an assembly location for the rotating motor 331. The rotating motor 331 drives the meshing gear 334 to drive the meshing tooth ring 333 to rotate, so that the rotating motor 331 accurately drives the meshing tooth ring 333 and the wire feeding reel 32 to rotate together by means of the meshing gear 334. More specifically, in order to adjust and process the torque and speed input by the rotating motor 331, so in Figure 8Among them, a rotating shaft 335 is assembled on the bearing vertical wall 31 beside the outer side of the meshing tooth ring 333. The rotating shaft 335 is arranged to extend along the first direction. The meshing gear 334 is sleeved on the rotating shaft 335, and the rotating motor 331 drives the rotating shaft 335 to drive the meshing gear 334 to rotate. Specifically, in combination with Figure 7 and Figure 8 , the rotating motor 331 and the meshing tooth ring 333 are arranged on the bearing vertical wall 31 on opposite sides, so that the arrangement of the rotating motor 331 and the meshing tooth ring 333 on the bearing vertical wall 31 is more compact and reasonable. The meshing gear 334 is sleeved on one end of the rotating shaft 335, and the other end of the rotating motor 331 opposite to the rotating shaft 335 is connected by a chain drive. Of course, it can also be connected by a gear drive or a belt drive, so it is not limited to the illustration shown in the drawings.

[0033] As Figure 4 and Figure 5 shown, the intermediate drive mechanism 22 includes a rotating motor 221, a mounting disk 222, an intermediate tooth ring 223 and an intermediate gear 224 that meshes with the intermediate tooth ring 223. The intermediate tooth ring 223 is rotatably assembled on the intermediate vertical wall 23, and the intermediate vertical wall 23 provides a supporting function and an assembly place for the intermediate tooth ring 223. The mounting disk 222 is arranged in a stacked manner with the intermediate tooth ring 223 along the first direction, and the mounting disk 222 is also fixedly connected to the intermediate tooth ring 223, so that the mounting disk 222 and the intermediate tooth ring 223 are fixed together and can rotate together. Three clamping structures 2221 are arranged on the mounting disk 223 at intervals along the circumferential direction of the mounting disk 222. Of course, the number of the clamping structures 221 can also be two or four, etc., so it is not limited to the illustration shown in the drawings. The intermediate wire reel 21 is clamped on the mounting disk 222 by means of the clamping structure 2221, so that the disassembly and assembly operation between the intermediate wire reel 21 and the mounting disk 222 is more convenient. The rotating motor 221 is installed on the intermediate vertical wall 23, and the intermediate vertical wall 23 provides a supporting function and an assembly place for the rotating motor 221. The rotating motor 22 also drives the intermediate gear 224 to rotate, and the rotating intermediate gear 224 drives the intermediate tooth ring 223 together with the intermediate wire reel 21 to make a rotating motion. The intermediate tooth ring 223 and the mounting disk 222 are each provided with a matching channel 2231(2222) that matches the intermediate channel 211 to ensure that the ring structure can smoothly slide through the intermediate tooth ring 223 and the mounting disk 222. Specifically, in Figure 5 Among them, a rotating shaft 226 is assembled on the intermediate vertical wall 23 beside the outer side of the intermediate tooth ring 223. The rotating shaft 226 is arranged to extend along the first direction. The intermediate gear 224 is sleeved on the rotating shaft 226, and the rotating motor 221 drives the rotating shaft 226 to drive the intermediate gear 226 to rotate. Such a design can adjust and process the torque and speed output by the rotating motor 221. More specifically, in Figure 5In it, the rotating motor 221 and the intermediate gear ring 223 are arranged on opposite sides of the intermediate vertical wall 23. Such a design makes the arrangement of the rotating motor 221 and the intermediate gear ring 223 on the intermediate vertical wall 23 more compact. The intermediate gear 224 is sleeved on one end of the rotating shaft 226, and the other end of the rotating motor 221 opposite to the rotating shaft 226 is connected by a belt drive to adjust the output torque and speed of the rotating motor 221. Of course, according to actual needs, the other end of the rotating motor 221 opposite to the rotating shaft 226 can also be connected by a chain drive or a gear drive, so it is not limited to the illustration in the drawings.

[0034] As Figure 1 and Figure 2 shown, to make the relative position between the seam welding device 10 and the intermediate wire reel device 20 more stable, the seam welding vertical wall 11 and the intermediate vertical wall 23 are fixed to the base 40, while the bearing vertical wall 31 of the wire feeding reel device 30 is fixed to the ground, but it is not limited to this.

[0035] Please refer to Figure 11 and Figure 12 shown, the structure of the steel cage seam welder 100 of the second embodiment of the present invention is basically the same as that of the steel cage seam welder 100 of the first embodiment, the difference lies in the wire feeding reel devices of the two. The following describes their differences.

[0036] (1) In the second embodiment, the bearing vertical wall 31 in the wire feeding reel device 30 includes a seat body 311 and a first vertical arm 312 and a second vertical arm 313 that are assembled on the seat body 311 and arranged at intervals in the first direction. A first safety chuck chuck 3121 is assembled on the first vertical arm 312, and a second safety chuck chuck 3131 aligned with the first safety chuck chuck 3121 is assembled on the second vertical arm 313. A central shaft 321 is assembled at the center of the wire feeding reel 32. One end of the central shaft 321 is clamped with the first safety chuck chuck 3121, and the other end of the central shaft 321 is clamped with the second safety chuck chuck 3131. Such a design makes the assembly between the wire feeding reel 32 and the bearing vertical wall 31 faster. Since the specific structures and working principles of both the first safety chuck chuck 3121 and the second safety chuck chuck 3131 are well known in the art, they will not be elaborated here. In addition, since the first vertical arm 312 and the second vertical arm 313 support the wire feeding reel 32 from both sides of the wire feeding reel 32, the wire feeding reel 32 can be made larger, and the rotation process is smoother and more stable.

[0037] In the first embodiment, the bearing vertical wall 31 is not made into a structure including a seat body 311 and a first vertical arm 312 and a second vertical arm 313 that are assembled on the seat body 311 and arranged at intervals in the first direction, and the bearing vertical wall 31 supports the wire feeding reel 32 from one side.

[0038] (2) In the second embodiment, the wire feeding drive mechanism 33 drives the first safety chuck 3121 to rotate, and the purpose of driving the wire feeding disk 32 together with the second safety chuck 3131 to rotate by the first safety chuck 3121 is specifically that the wire feeding drive mechanism 33 includes a rotary motor 331 installed on the base 311 and located beside the side of the first vertical arm 312 facing away from the second vertical arm 313. The rotary motor 331 is connected to the first safety chuck 3121 through a belt drive. Of course, it can also be connected through a chain drive or a gear drive.

[0039] In the first embodiment, the structure of the wire feeding drive mechanism 33 is different from that of the wire feeding drive mechanism 33.

[0040] Except for the above differences, the others are the same as those in the first embodiment, so they will not be elaborated here.

[0041] Compared with the prior art, the cage rolling welder 100 (100) of the present invention adds a wire feeding disk device 30 (30) beside the intermediate wire disk device 20, so that the intermediate wire disk device 20 plays the role of an intermediate bridge, responsible for taking in and paying out the welding wire 210 released by the wire feeding disk device 30 (30); therefore, during the cage rolling welding process, when the welding wire 210 of the wire feeding disk device 30 (30) is used up and needs to be replaced, at this time, it is not necessary to move the steel bars 220 arranged in a ring structure in the welding channel 111 of the rolling welding vertical wall 11, the intermediate channel 211 of the intermediate wire disk 21, and the docking channel 231 of the intermediate vertical wall 23 away from the intermediate channel 211 of the intermediate wire disk 21 to replace it, so the disk changing time is saved and the efficiency is improved, and the labor is saved; when the used wire feeding disk 32 (32) is larger than the intermediate wire disk 21, the disk changing time can be saved and the efficiency can be improved, and the waste of the welding wire 210 can be reduced. In addition, since the intermediate wire disk 21 is matched with the rolling welding device 10, its size is restricted by the industry general standard, while the wire feeding disk 32 (32) in the wire feeding disk device 30 (30) added beside the intermediate wire disk device 20 is not restricted by this, so the wire feeding disk 32 (32) can be designed larger.

[0042] It should be noted that during the cage rolling welding process, the model base 230 and the steel bars 220 arranged in a ring structure on the model base 230 need to slide and move along the first direction to ensure that the welding wire 210 is welded at positions separated by a certain distance in the ring structure, and the sliding movement of the model base 230 is realized by an external traction mechanism; since the welding wire 210 needs to be wound from the outside and welded to the ring structure, correspondingly, the steel bars 220 forming the ring structure need to pass through the welding channel 111 of the rolling welding vertical wall 11, the intermediate channel 211 of the intermediate wire disk 21, and the alignment channel 231 of the intermediate vertical wall 23, etc. However, these are well known in the art.

[0043] The above-disclosed are only the preferred examples of the present invention, and thus cannot be used to limit the scope of the rights of the present invention. Therefore, all equivalent changes made according to the claims of the present invention fall within the scope covered by the present invention.
