Description

Technical Field

[0001] The invention relates to the technical field of bed net frame processing, in particular to a bed net frame production line. Background Art

At present, the main materials for making spring mattresses are frames and spring cores. Among them, the frame first needs to straighten the steel wire during assembly, and then cut the straightened steel wire according to production needs. The staff will place the cut steel wire on the bending equipment, bend the steel wire into a square shape according to product requirements, and finally press the two free ends of the steel wire together through the sleeve to form the required frame, and finally form the required bed net frame.

The supporting horizontal side can provide support for the steel wire after it falls along the guide, so that the steel wire is always in a horizontal state after it falls, which is convenient for subsequent wire feeding operations;

[0013] By setting the supporting horizontal side to correspond to the position of the clamping assembly, the steel wire clamped by the clamping assembly is in a horizontal state, which is convenient for feeding the wire to the bending mechanism;

[0014] The inclined guiding bevel can provide a buffering effect for the falling of the steel wire, thereby preventing the steel wire from causing damage to the correction mechanism below after falling under the action of its gravity.

[0015] Furthermore, it also includes a horizontal distance adjustment component 1 and a horizontal distance adjustment component 2 having the same structure and arranged in parallel with the first direction, wherein the horizontal distance adjustment component 1 includes a distance adjustment bracket and a bidirectional distance adjustment module, and a bending component is respectively arranged at both ends of the bidirectional distance adjustment module in the length direction. By arranging the horizontal distance adjustment component, the length of the middle section of the steel wire can be corrected so that its size meets the production and processing requirements of the bed net frame, further ensuring the processing efficiency of the bed net frame

[0016] Furthermore, the bending assembly includes a vertically arranged fixed shaft and a bending shaft, the fixed shaft and the bottom of the bending shaft are fixedly connected by a connecting frame, and a wire placement groove is left between the two for horizontal placement of the steel wire, and the driving end of the shaft driving part is coaxially arranged with the fixed shaft, and can drive the fixed shaft to rotate along its axis, so that the steel wire between the fixed shaft and the bending shaft can be bent under the rotation of the bending shaft.

[0017] Furthermore, the assembly platform also includes a positioning groove for accommodating the sleeve, a mounting seat and limiting plug plates located on both sides of the mounting seat, the positioning groove is defined between the two limiting plug plates, the steel wire through holes are symmetrically arranged on both sides of the positioning groove and are connected thereto, the steel wire moving mechanism includes a material moving base plate that moves toward or away from the assembly platform under the action of a driving part, and the material moving base plate is provided with two steel wire clamps that can move toward or away from each other in the left and right directions, and the steel wire clamps are used to clamp the ends of the steel wire.

[0018] Furthermore, the limit plug plate includes an upper plug plate and a lower plug plate used in conjunction with each other, the lower plug plate is fixed to the mounting seat, one end of the upper plug plate is pivoted to the lower plug plate, and the other end can be rotated to abut against the lower plug plate under the action of a rotating drive member, and when the upper plug plate abuts against the lower plug plate, the steel wire through hole is formed between the upper plug plate and the lower plug plate. The steel wire through hole is openable or closed by the cooperation of the upper plug plate and the lower plug plate. When closed, the steel wire can be accurately inserted into the sleeve.

[0020] Since the two ends of the bent steel wire need to be joined together through the sleeve during the production of the frame, in actual application, the first grabbing substrate is set near the position where the two ends of the steel wire are joined, and then the two steel wire clamps set thereon can respectively grab the two ends of the steel wire located on the same side of the frame, so as to utilize the subsequent joining operation of the two ends of the steel wire through the sleeve; and the steel wire clamps move towards or away from each other to cooperate with the insertion of the two ends of the steel wire into the sleeve.

DETAILED DESCRIPTION

[0047] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0048] See attached Figures 1 to 2 As shown, a bed net frame production line in this embodiment includes a feeding and straightening mechanism 1, a wire cutting mechanism 2, a wire feeding correction mechanism 3 and a wire bending mechanism 4 which are arranged in sequence along a first direction; a frame grabbing and moving mechanism 6 is arranged above the wire bending mechanism 4, and a wire interface fixing mechanism 5 is arranged on the side away from the wire feeding correction mechanism 3; in the present invention, the steel wire after being loaded on the reel is straightened by the feeding and straightening mechanism 1, so as to facilitate the subsequent bending of the steel wire into the shape of a bed net frame, and the wire cutting mechanism 2 can adjust the length of the cut steel wire according to the required size of the bed net frame, and the above-mentioned feeding and straightening mechanism 1 and the wire cutting mechanism 2 are both prior art, and their structures are not described in detail here;

[0049] See attached Figures 5 to 7 The bed net frame is square and has four bending points. When not bent, the steel wire can be divided into three continuous sections, namely, an initial section, a middle section and a tail section. The middle section is located between two bending components 42. The initial section and the middle section can be bent into the shape of the bed net frame under the action of the four bending components 42.

[0050] See attached Figures 2 to 4 The cut steel wire falls to the wire feeding correction mechanism 3, and the wire feeding correction mechanism 3 is used to transfer the steel wire that has been straightened by the feeding straightening mechanism 1 and cut by the steel wire cutting mechanism 2 to the steel wire bending mechanism 4 for bending; compared with the prior art in which manual wire feeding cannot accurately measure the length of the initial bending section of the steel wire end, resulting in the connection point and the sleeve not being able to correspond and be pressed and fixed when the bending machine bends the steel wire, the wire feeding correction mechanism 3 in the present invention can adjust the position of the steel wire in the horizontal direction relative to the steel wire bending mechanism 4, and automatically adjust the length of the initial bending section of the steel wire to ensure that the length of the two ends of the steel wire after bending can be normally fixed by the sleeve, thereby effectively improving the production efficiency of the bed net frame;

[0051] The wire feeding correction mechanism 3 includes a wire threading bracket 31 arranged along a first direction and a correction component 32 located on one side of the length direction of the wire threading bracket 31. The correction component 32 includes a displacement component 33 that can adjust the horizontal displacement of the wire. The displacement component 33 includes a clamping component 331 and a driving component. The clamping component 331 can clamp one end of the cut wire and move back and forth in the horizontal direction under the driving action of the driving component.

[0052] The displacement assembly 33 can move back and forth under the driving action of the driving assembly, thereby being able to adjust the position of the steel wire in the horizontal direction relative to the external bending mechanism, and automatically adjust the length of the initial bending section of the steel wire to ensure that the length of the two ends of the steel wire can be normally fixed by the sleeve after bending, thereby ensuring the production efficiency of the bed net frame.

[0053] An open wire groove is provided at the bottom of the wire threading bracket 31 so that the wire can fall downward to the correction mechanism below after being cut.

[0054] A plurality of guide blanking components 35 are arranged at intervals on the steel wire threading bracket 31 along the steel wire threading direction, and the guide blanking components 35 include guide members 352 and stop members 351. A limited space is reserved between the guide members 352 and the stop members 351 for the steel wire to pass through from top to bottom, and the cut steel wire can fall to the correction mechanism under the guidance of the guide members 352. The guide blanking components 35 can provide guidance for the fall of the cut steel wire to prevent the position deviation during the fall from affecting the subsequent size correction.

[0055] The guide member 352 and the limit member 351 are arranged on both sides of the steel wire threading bracket 31 in the vertical direction. The guide member 352 includes a connecting section, a guide bevel 3521, a guide vertical side 3522 and a supporting horizontal side 3523 which are connected in sequence. The end of the guide bevel 3521 connected to the guide vertical side 3522 is inclined toward the direction of the limit member 351. The supporting horizontal side 3523 and the bottom end of the limit member 351 leave a displacement channel for the steel wire to horizontally move out of the guide blanking assembly 35. The supporting horizontal side 3523 corresponds to the position of the clamping assembly 331. The supporting horizontal side 3523 can provide support for the steel wire after it falls along the guide member 352, so that the steel wire is always in a horizontal state after it falls, which is convenient for the subsequent wire feeding operation;

[0056] By arranging the supporting horizontal edge 3523 to correspond to the position of the clamping assembly 331, the steel wire clamped by the clamping assembly 331 is in a horizontal state, which facilitates the wire feeding to the bending mechanism;

[0057] The inclined guiding bevel 3521 can provide a buffering effect for the falling of the steel wire, thereby preventing the steel wire from causing damage to the correction mechanism below after falling under the action of its gravity.

[0058] In some embodiments, the distance between the stopper 351 and the guide vertical edge 3522 is smaller than the distance between the connecting section and the guide vertical edge 3522, so that a better guiding effect is obtained when the steel wire falls from top to bottom. The setting of the stopper 351 can also prevent the steel wire from deviating from the range in which the clamping assembly 331 can clamp the steel wire when the steel wire falls, so as to avoid affecting the subsequent wire feeding operation.

[0059] It also includes a wire support frame 34, which includes a cross bar 341 arranged parallel to the wire threading bracket 31, and a plurality of frames 342 are arranged on the cross bar 341 along its length direction. The frames 342 include a transversely arranged overlapping edge 343, which is located below the wire threading bracket 31 and is arranged in the direction of the guide member 352.

[0060] After being cut by the wire cutting mechanism 2, the steel wire will fall onto the frame 342 in advance, and the mounting edge 343 will support the steel wire. Compared with the steel wire falling directly from the wire threading bracket 31 to the correction mechanism below, in the present application, the mounting edge 343 will buffer the falling of the steel wire in advance, and the steel wire will be more stable when it moves from the mounting edge 343 to the lower material component 35 and falls.

[0061] Specifically, the distance between the lap edge 343 and the lower surface of the wire threading bracket 31 is just enough for a wire to move forward and backward. If the distance is too large, the wire will easily deviate from the lap edge 343 and directly pass through the guide blanking assembly 35 and fall onto the correction mechanism. If the distance is too small, the wire cannot be moved out of the space.

[0062] In some embodiments, the frame 342 is arranged in an L-shape, and its vertical side is used to fix the frame 342 on the crossbar 341, and the horizontal side is the mounting side 343 that can support the steel wire.

[0063] Regarding the setting of the cross bar 341, in some embodiments, the cross bar 341 drives the overlapping edge 343 to rotate in a direction away from the guide blanking assembly 35 under the action of external force, so that the steel wire placed on the overlapping edge 343 slides along the inclined overlapping edge 343 until it abuts against the guide member 352, and slides and falls along the inner side of the guide member 352 until it falls into the correction assembly 32.

[0064] A limited passage for the steel wire to pass through is left between the end of the lap edge 343 and the connecting section to ensure that the steel wire can abut against the inner wall of the guide member 352 after leaving the lap edge 343 and slide close to the inner wall of the guide member 352 until it falls on the supporting horizontal edge 3523.

[0065] The correction component 32 includes a correction bracket and a displacement bracket 333 . The displacement bracket 333 supports the setting of the clamping component 331 .

[0066] The clamping assembly 331 is a pneumatic clamping jaw, and a wire support plate 334 is provided on one side of the pneumatic clamping jaw close to the feeding and straightening mechanism 1, and the top of the wire support plate 334 abuts against the bottom of the wire clamped on the pneumatic clamping jaw. The wire support plate 334 is arranged horizontally, and when the wire falls onto the supporting horizontal edge 3523 under the guidance of the guiding unloading assembly 35, the wire support plate 334 can provide an upward supporting force for the wire, and support the part of the wire that is not supported by the supporting horizontal edge 3523, so as to avoid bending of the wire and ensure the stability of the pneumatic clamping jaw in clamping the wire and feeding the wire.

[0067] It should be noted that the clamping assembly 331 is not limited to being a pneumatic clamp, as long as it can clamp one end of the steel wire.

[0068] The driving assembly is a belt transmission assembly 332 , which is a prior art and its structure will not be described in detail here.

[0069] It should be noted that the first direction in the present application is parallel to the direction of steel wire feeding.

[0070] See attached Figures 5 to 7 After the size of the steel wire is adjusted, the steel wire bending mechanism 4 located on the side thereof starts to work. The steel wire bending mechanism 4 includes a plurality of bending components 42 and an axis driving part 43 which are consistent with the bending point positions on the formed bed net frame. The steel wire is bent by the bending components 42;

[0071] It also includes a horizontal distance adjustment component 1 44 and a horizontal distance adjustment component 2 45 having the same structure and arranged in parallel with the first direction in sequence, wherein the horizontal distance adjustment component 1 44 includes a distance adjustment bracket 442 and a bidirectional distance adjustment module 441, and a bending component 42 is respectively arranged at both ends of the bidirectional distance adjustment module 441 in the length direction;

[0072] By setting the horizontal distance adjustment component, the length of the middle section of the steel wire can be corrected so that its size meets the production and processing requirements of the bed net frame, further ensuring the processing efficiency of the bed net frame.

[0073] Specifically, during adjustment, the bidirectional distance adjustment module 441 can drive the two bending components 42 to move toward or away from each other to adjust the length of the middle section of the wire. It should be noted that it is not limited to the bidirectional distance adjustment module 441, and it can also be a combination of a driving motor and a bidirectional screw rod, and can also realize the movement of the two distance adjustment brackets 442 toward or away from each other.

[0074] The bending assembly 42 includes a vertically arranged fixed shaft 421 and a bending shaft 422. The fixed shaft 421 and the bottom of the bending shaft 422 are fixedly connected by a connecting frame, and a wire placement groove is left between the two for the steel wire to be placed horizontally. The driving end of the shaft driving part 43 is coaxially arranged with the fixed shaft 421, and can drive the fixed shaft 421 to rotate along its axis, so that the steel wire located between the fixed shaft 421 and the bending shaft 422 can be bent under the rotation of the bending shaft 422.

[0075] The driving end of the shaft driving part 43 can drive the fixed shaft 421 to rotate. Since the fixed shaft 421 and the bottom of the bending shaft 422 are fixedly connected by a connecting frame, when the fixed shaft 421 rotates, the bending shaft 422 also rotates synchronously with the fixed shaft 421 accordingly. Specifically, the bending shaft 422 rotates 90 degrees with the center of the fixed shaft 421 as the center and the distance between the central axes of the two as the radius, so that the initial section and the tail section of the steel wire are bent at an angle of 90 degrees with the middle section respectively. The steel wire is bent in sequence under the action of multiple bending components 42 to form a bed net frame.

[0076] Specifically, the two bending components 42 close to the steel wire feeding end perform the first bend on the steel wire, bending the initial section and the tail section to be 90 degrees with the middle section, and the two bending components 422 away from the steel wire feeding end perform the second bend on the steel wire, so that the free ends of the initial section and the tail section are butt-jointed after the second bend to form a complete bed net frame.

[0077] The shaft driving part 43 includes a vertically arranged shaft driving motor 431 and a reducer 432 located at its driving end. A hexagonal shaft 433 is horizontally penetrated on the reducer 432. Both ends of the hexagonal shaft 433 are respectively connected to a gear transmission box 434. The gear transmission box 434 is fixedly connected to the bottom of the fixed shaft 421 through a rotator. Two meshing driving gears and driven wheels are arranged in the gear transmission box 434. The hexagonal shaft 433 is connected to the driving gear through a bearing. When it rotates, it can drive the driving gear to rotate, so that the driven wheel also rotates. The driven wheel is connected to the bottom of the fixed shaft 421 through a diverter 435, and can drive the fixed shaft 421 to rotate, thereby realizing automatic bending of the steel wire.

[0078] It should be noted that the rotator is a prior art, and its specific structure is not described in detail here. The shaft drive motor 431 can also be replaced by a dividing plate, as long as it can drive the hexagonal shaft 433 running through the reducer 432 to rotate, and is not limited to the shaft drive motor 431.

[0079] See attached Figure 1, and also includes support optical axis frames 41 arranged on both sides of the shaft driving part 43 in the width direction, and the end of the support optical axis frame 41 close to the steel wire feeding is tilted toward the direction away from the shaft driving part 43, and the other end is close to the bending assembly 42 away from the steel wire feeding side. By setting the support optical axis frame 41, the side away from the middle section of the steel wire can always be placed on the support optical axis frame 41 during the process of bending the initial section and the tail section of the steel wire from the bending assembly 42 close to the steel wire feeding side to the bending assembly 42 away from the steel wire feeding side, so as to ensure that the steel wire is always in a horizontal state, avoiding affecting the subsequent bending.

[0080] It also includes a guide and limit assembly 46, which includes an inclined guide plate 461 and a guide frame 462. The two bending assemblies 42 on the opposite sides of the wire feeding side are respectively provided with an inclined guide plate 461 and a guide frame 462. The inclined guide plate 461 is fixedly connected to the bending assembly 42 through a guide plate mounting seat. The inclined guide plate 461 is vertically arranged, and its top is inclined toward the direction close to the bending assembly 42. The setting of the inclined guide plate 461 can provide guidance for the end of the wire away from the middle section to enter the two bending assemblies 42 on the side away from the wire feeding end for secondary bending after the wire passes through the bending assembly 42 close to the feeding end thereof, so as to ensure that the wire can accurately enter the bending assembly 42 for secondary bending, thereby improving the efficiency of secondary bending.

[0081] It also includes a limit frame 463, the guide frame 462 includes a support surface located below the bent steel wire and a limit surface perpendicular to the support surface, the limit frame 463 is vertically arranged, and one side of the limit frame 463 abuts against the side of the support surface away from the limit surface, and the limit frame 463, the support surface and the limit surface constitute a limited space for horizontal placement of the steel wire and for limiting its front and rear movement. By providing the guide frame 462 and the limit frame 463, it is prevented that the end of the steel wire rebounds toward the direction of the bending assembly 42 away from the second bending after the first bending, thereby ensuring the stability of the subsequent second bending of the steel wire.

[0082] It should be noted that the front-to-back direction here refers to the direction parallel to the hexagonal axis 433 .

[0083] It also includes a return assembly 47, which includes a return support plate 471 mounted on the shaft drive part 43, a return drive member is horizontally arranged on the return support plate 471 in the direction of the shaft drive part 43, and a return bracket 4731 is connected to the driving end of the return drive member. When a second bending is to be performed, the driving end of the return drive member is in an extended state, driving the return bracket 473 to move in a direction away from the return drive member, so that after the second bending, the free ends of both ends of the steel wire are located between the return bracket 473 and the return drive member, and then the driving end of the return drive member is retracted. At this time, the return bracket 473 can push the steel wire from the rear side of the steel wire to move toward the direction close to the return drive member to return, so that the two free ends of the steel wire are just butted, which is convenient for the subsequent butting and pressing operation.

[0084] Specifically, the return drive is a return cylinder 472, and the extension and retraction of the piston rod of the return cylinder 472 can drive the return bracket 4731 to drive the free ends of the initial section and the tail section after the second bending to move away from or close to the return drive.

[0085] The return bracket 473 is L-shaped, and includes an abutment surface 474 vertically arranged toward the return drive member. When the drive end of the return drive member is retracted, the abutment surface 474 can push the steel wire after the second bending to automatically return to the center.

[0086] See attached Figures 8 to 10 In order to enable the two free ends of the bent steel wire to be accurately inserted into the sleeve and pressed and fixedly connected, a steel wire interface fixing mechanism 5 is also provided, specifically, comprising an assembly platform 51 and a steel wire moving mechanism 52 and a sleeve pressing mechanism 53 located on both sides of the assembly platform 51, the assembly platform 51 comprising a steel wire through hole 512, the steel wire moving mechanism 52 can clamp the two free ends of the bent steel wire and insert them into the corresponding steel wire through holes 512;

[0087] The assembly platform 51 further includes a positioning groove 511 for accommodating the sleeve, a mounting seat 513, and limiting plug plates 514 located on both sides of the mounting seat 513. The positioning groove 511 is defined between the two limiting plug plates 514. The steel wire through holes 512 are symmetrically arranged on both sides of the positioning groove 511 and are connected thereto. The inner diameter of the steel wire through holes 512 gradually increases from the direction close to the positioning groove 511 to the direction away from the positioning groove 511. The position of the steel wire is guided and corrected by setting the diameter of the steel wire through holes 512 from large to small, so that the steel wire can be aligned with the sleeve in the positioning groove 511, and then smoothly inserted into the sleeve.

[0088] The wire moving mechanism 52 includes a material moving base plate 521 that moves toward or away from the assembly platform 51 under the action of a driving unit, and the material moving base plate 521 is provided with two wire clamping members 522 that can move toward or away from each other in the left and right directions, and the wire clamping members 522 are used to clamp the two free ends of the bent wire. The movement of the wire clamping members 522 toward or away from each other on the material moving base plate 521 is to cooperate with the action of inserting the wire into the sleeve.

[0089] See attached Fig. 9 In some embodiments, the limit plug plate 514 may adopt a split structure. Specifically, the limit plug plate 514 includes an upper plug plate and a lower plug plate used in conjunction with each other, and the lower plug plate is fixedly connected to the mounting seat 513. One end of the upper plug plate is pivotally connected to the lower plug plate, and the other end can swing to abut against the lower plug plate under the action of the rotating drive member, and when the upper plug plate abuts against the lower plug plate, a steel wire through hole 512 is formed between the upper plug plate and the lower plug plate. Through the cooperation of the upper plug plate and the lower plug plate, the steel wire through hole 512 is in an openable or closed state. When closed, the steel wire can be accurately inserted into the sleeve. When opened, the pressed frame can leave the steel wire through hole 512 and enter the next station through the steel wire moving mechanism 52.

[0090] In some embodiments, the rotary drive member includes a drive cylinder, a cylinder barrel of the drive cylinder is fixedly connected to the platform base, and a piston rod of the drive cylinder is hinged to the upper insert plate.

[0091] In some embodiments, see Appendix Fig.10 The sleeve pressing mechanism 53 includes a fixed die 531 and a movable die 532 respectively located on both sides of the positioning groove 511 (in the front-to-back direction). The fixed die 531 is fixedly connected to the mounting seat 513, and a fixed pressing surface for the sleeve to abut is provided on the side facing the positioning groove 511; the movable die 532 can move toward or away from the positioning groove 511 under the action of the pressing driving member 533, and a movable pressing surface is provided on the side facing the positioning groove 511. When the sleeve is placed in the positioning groove 511, the sleeve can abut on the fixed pressing surface to enhance the positioning of the sleeve in the positioning groove 511; then the pressing driving member 533 drives the movable die 532 to move, so that the sleeve can be pressed and fixed on the steel wire under the joint action of the fixed die 531 and the movable die 532.

[0092] Furthermore, the sleeve pressing mechanism 53 also includes a spring, one end of which is connected to the mounting seat 513, and the other end is connected to the movable die 532. The movable die 532 can be reset by the spring after pressing. When the sleeve is placed in the positioning groove 511, the sleeve is fixed by inserting a steel wire into the sleeve, and then the movable die 532 is driven to move by the pressing driving member 533, so that the sleeve can be pressed and fixed on the steel wire under the joint action of the fixed die 531 and the movable die 532.

[0093] The pressing driving member 533 includes a pressing oil cylinder and a pressing guide rod. The pressing guide rod is arranged along the front-back direction, one end of which is fixedly connected to the fixed die 531, and the other end is passed through the movable die 532. The pressing oil cylinder is fixedly connected to the mounting seat 513, and its piston rod is fixedly connected to the movable die 532. The moving direction of the movable die 532 is guided by the setting of the pressing guide rod.

[0094] In some embodiments, see Appendix Fig.10 As shown, the sleeve moving mechanism 54 includes a material picking plate 542 that can move toward or away from the positioning groove 511 under the action of the sleeve driving member 541. The material picking plate 542 is tilted, and one end of the material picking plate facing the positioning groove 511 is provided with a magnetic suction member for magnetically sucking the sleeve. The setting of the magnetic suction member can magnetically fix the sleeve to prevent the sleeve from falling during the material transfer process. The sleeve is fixed in the positioning groove 511 by inserting a steel wire into the sleeve, and the steel wire can be kept fixed under the action of the steel wire clamping member 522, so that the sleeve overcomes the magnetic suction effect of the magnetic suction member and remains fixed in the positioning groove 511.

[0095] Specifically, the casing driving member 541 includes a gear and a rack that mesh with each other. The gear is coaxially mounted on the casing motor and rotates under the action of the casing motor. The rack is fixed to the material taking plate 542 along the moving direction of the material taking plate 542. When the casing motor drives the gear to rotate, the rack meshes with each other and drives the material taking plate 542 to move.

[0096] In some embodiments, as shown in the drawings, a sleeve loading mechanism 55 is further provided on the assembly platform 51 , and a discharge port of the sleeve loading mechanism 55 is aligned with the material taking plate 542 to facilitate the material taking operation of the material taking plate 542 .

[0097] See attached Figures 11 to 12 The frame grabbing and moving mechanism 6 is used to grab and move the frame after forming and fixing to the next station. The frame grabbing and moving mechanism 6 is a cross slide structure, and the wire moving mechanism 52 is located on the first grabbing substrate 641, which can drive the wire clamping member 522 clamped with the wire to move toward or away from the sleeve pressing mechanism 53.

The lifting mechanism 62 includes a lifting frame plate 622 that can be lifted and moved under the action of a lifting drive 621. The transverse movement mechanism 63 is installed on the lifting frame plate 622, which includes a transverse movement substrate 632 that can move back and forth under the action of a transverse movement drive 631.

The first grabbing substrate 641 and the second grabbing substrate 642 are respectively provided with steel wire clamps 522 for grabbing the frame, and the two groups of steel wire clamps 522 can respectively grab the three sides of the frame that are perpendicular to each other.

[0099] Since the two ends of the bent steel wire need to be joined together through the sleeve during the production of the frame, in actual application, the first grabbing substrate is set near the position where the two ends of the steel wire are joined, and then the two steel wire clamps set thereon can respectively grab the two ends of the steel wire located on the same side of the frame, so as to utilize the subsequent joining operation of the two ends of the steel wire through the sleeve; and the steel wire clamps move towards or away from each other to cooperate with the insertion of the two ends of the steel wire into the sleeve. That is, the steel wire clamps can not only grab the frame, but also have the function of grabbing the two ends of the steel wire and feeding the two ends of the steel wire into the sleeve.

[0100] The movement of the grasping mechanism 64 in the front-to-back direction is realized by the setting of the transverse movement mechanism 63, and the movement of the grasping mechanism 64 in the up-down direction is realized by the setting of the lifting mechanism 62, so that the grasping mechanism 64 can drive the frame to move horizontally (front-to-back direction) or vertically (up-down direction) to meet the movement and circulation of the frame in different workstations; in the grasping mechanism 64, the position layout of the first grasping substrate 641 and the second grasping substrate 642 and the cooperation of multiple groups of wire clamps 522 can grasp at multiple points of the frame, thereby improving the stability of the frame grasping and ensuring the stable movement of the frame.

[0101] The lifting drive member 621 includes a fixed plate 623, an elevator, and a guide rod. The lifting guide plate 624 is fixedly connected to the base 61.

There are multiple guide rods, one end of each guide rod is fixedly connected to the lifting base plate 625, and the other end is penetrated on the fixed plate 623. The lifting base plate 625 is driven up and down by the elevator, thereby driving the entire lifting frame plate 622 to move up and down, and the lifting direction of the lifting frame plate 622 can be guided by the setting of the guide rod. Furthermore, the lifting drive member 621 also includes a lifting guide plate 624, which is located below the fixed plate 623 and fixedly connected to the base 61, and is provided with guide perforations corresponding to the screw rod and the guide rod. The setting of the guide perforations is used to guide the piston rod and the guide rod.

[0103] In some embodiments, the frame body is provided with a guide rail arranged in the front-to-back direction, and the lateral movement base plate 632 is connected with a lateral movement guide plate 633 that can move along the guide rail. The cooperation between the lateral movement guide plate 633 and the guide rail further improves the stability of the lateral movement base plate 632 along the lifting frame plate 622.

The driving gear is fixedly sleeved on the synchronous shaft, and a toothed belt is wound between it and the driven wheel. The toothed belt is provided with a connecting seat for connecting the transverse base plate 632. The cooperation of the driving gear, the driven wheel, and the toothed belt makes the transverse movement of the connecting seat more stable, which is beneficial to the transverse stability of the transverse base plate 632 and the grabbing mechanism 64.

[0105] Furthermore, the transverse driving member 631 further includes a clamping part, which includes a pair of cantilevers 65 and a pressure wheel 66. The pair of cantilevers 65 are respectively arranged on both sides of the toothed belt, and one end of the cantilever 65 is fixed to the lifting base plate 625, and the other end is suspended; the suspended ends of the pair of cantilevers 65 are commonly connected to a cantilever connecting shaft; the pressure wheel 66 is sleeved on the cantilever connecting shaft and can press against the toothed belt. The setting of the clamping part can tension the toothed belt to ensure the stable transmission of the toothed belt, which is conducive to the stable movement of the transverse base plate 632.

[0106] Furthermore, the pressing wheel 66 includes a wheel body, and the two side edges of the wheel body are respectively provided with limit lifting edges for limiting the position of the toothed belt. When the toothed belt is driven, the toothed belt is always located between the two limit lifting edges to prevent the toothed belt from escaping from the pressing force of the pressing wheel 66.
