DETAILED DESCRIPTION

[0043] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in combination with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0044] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention as claimed, but rather merely represents selected embodiments of the present invention. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort are also within the scope of protection of the present invention.

[0045] like Figure 1-10As shown, an automatic processing equipment for a mesh frame includes a material trough 1, a material suction mechanism 2, a bending mechanism 3 and a butt welding mechanism 4. Four bending mechanisms 3 are provided, which are arranged side by side on the front side of the material trough 1; the material suction mechanism 2 can move back and forth above the material trough 1 and the bending mechanism 3; the butt welding mechanism 4 is located on the front side of the bending mechanism 3; the material suction mechanism 2 can transfer the material strip in the material trough 1 to the bending mechanism 3, and the two end points of the material strip after bending are welded by the butt welding mechanism 4.

[0046] The automatic processing equipment further comprises an equipment frame 5 , on which the material trough 1 , the material suction mechanism 2 , the bending mechanism 3 and the butt welding mechanism 4 are all mounted.

[0047] Preferably, the two end plates 11 of the trough 1 are detachable structures and can be adjusted according to the length of the material strip to adapt to the discharge of frames of different specifications.

[0048] Specifically, a plurality of mounting holes are provided on the bottom plate 314 of the trough 1 , and the position of the end plate 11 can be adjusted by fitting the end plate 11 with the mounting holes at different positions.

[0049] The function of the suction mechanism 2 is to transfer the material strips in the material trough 1 to the bending mechanism 3. In order to facilitate suction and unloading, the suction mechanism 2 includes a suction mounting plate 21 that can move up and down, and a suction seat 22 that is arranged below the suction mounting plate 21 and can move up and down. Pushing plates 23 fixed to the bottom of the suction mounting plate 21 are provided on both sides of the suction seat 22.

[0050] When sucking the material strip, the entire material suction mechanism 2 needs to be moved to the top of the material trough 1, and the material suction mounting plate 21 moves down, driving the material suction seat 22 to move into the material trough 1, and the material strip is adsorbed under the material suction seat 22, and then the material suction mounting plate 21 moves up and resets, and moves to the top of the bending mechanism 3, and then the material suction mounting plate 21 moves down. After moving into place, the material suction seat 22 moves up to drive the material strip to rise, and the pushing plate 23 blocks the material strip, and then the material strip is separated from the material suction seat 22 and falls onto the bending mechanism 3.

[0051] Preferably, when sucking material, the bottom position of the suction seat 22 is not higher than the bottom position of the push plate 23 to avoid the push plate 23 affecting the adsorption of the material strip.

[0052] In order to achieve the adsorption of the material strips, a material adsorption groove 24 is provided at the bottom of the material adsorption seat 22 , and a magnetic component is installed in the material adsorption groove 24 .

[0053] Specifically, the suction groove 24 is an arc-shaped groove, which can better match the shape of the material strips to ensure that only one strip is sucked at a time.

[0054] In order to facilitate the installation of the magnetic member, a plurality of mounting holes are evenly arranged in the suction chute 24, and the magnetic member is installed in the mounting holes.

[0055] Preferably, the magnetic member may be selected from but is not limited to a strong magnet.

[0056] In order to enable the suction seat 22 to move up and down, a suction cylinder 25 is installed on the suction mounting plate 21 , and a piston rod of the suction cylinder 25 passes downward through the suction mounting plate 21 and is connected to the suction seat 22 .

[0057] In this embodiment, two suction cylinders 25 are provided, and the piston rods of the two cylinders extend and retract synchronously, thereby driving the suction seat 22 to move up and down below the suction mounting plate 21 .

[0058] The number of the suction cylinders 25 is not limited to two and can be selected as needed.

[0059] In order to guide the lifting and lowering of the material suction seat 22, a guide shaft 26 is installed on the material suction seat 22, and the upper end of the guide shaft 26 passes through a linear bearing installed on the material suction mounting plate 21.

[0060] Preferably, in order to be able to check whether there is material strip absorbed in the suction trough 24, a bracket is installed at one end of the suction seat 22, and a proximity switch I 27 with a detection head facing downward is installed on the bracket.

[0061] In order to achieve the lifting and lowering of the suction mounting plate 21, a slide plate 28 that can move forward and backward is provided above the suction mounting plate 21. A lifting cylinder I 29 is installed on the slide plate 28. The piston rod of the lifting cylinder I 29 passes downward through the slide plate 28 and is connected to the suction mounting plate 21.

[0062] In order to guide the lifting and lowering of the material suction mounting plate 21 , a guide column 210 is installed on the material suction mounting plate 21 , and the upper end of the guide column 210 passes through a linear bearing installed on the slide plate 28 .

[0063] Since the material trough 1 is located at the rear side of the bending mechanism 3, in order to realize the reciprocating movement of the suction mechanism 2 between the material trough 1 and the bending mechanism 3 and realize automatic loading, the slide 28 is connected to a synchronous belt 51, which can drive the slide 28 to move back and forth.

[0064] Specifically, the synchronous belt 51 is set on the equipment frame 5, and the pulley at the rear end of the synchronous belt 51 is connected to the motor 52. The motor 52 drives the synchronous belt 51 to rotate around the two pulleys, and then drives the feeding mechanism to move back and forth through the synchronous belt 51.

[0065] Preferably, the equipment frame 5 is provided with guide rails Ⅰ53 in the front and rear directions, and the bottom of the slide plate 28 is provided with a slider that cooperates with the guide rails Ⅰ53. The cooperation between the guide rails Ⅰ53 and the slider can guide the forward and backward movement of the feeding mechanism.

[0066] In order to complete the bending action, the bending mechanism 3 includes a fixed block 31, a bending column 32 that can rotate around the fixed block 31, and a pressing block 33 located at the rear side of the fixed block 31 and can move forward.

[0067] When bending, the material strip is placed between the fixed block 31 and the pressing block 33, and the bending column 32 is also on the rear side of the material strip and located behind the outer side of the fixed block 31. After the material strip is placed in place, the pressing block 33 moves forward and cooperates with the fixed block 31 to fix the material strip. At this time, the bending column 32 is rotated forward to achieve the bending of the material strip.

[0068] Before bending, the lateral position of the material strip needs to be adjusted. A pushing baffle 512 installed on the equipment frame 5 is provided at one end of the material discharge position of the bending mechanism 3, and a fixed baffle 513 is installed at the other end, and a pushing cylinder 514 is provided on the outside of the pushing baffle 512.

[0069] In order to facilitate the installation of the fixed block 31 and the bending column 32, the bending mechanism 3 also includes a bending seat 34, a central shaft 35 installed in the bending seat 34, and a rotating sleeve 36 arranged outside the central shaft 35. The fixed block 31 is installed on the top of the central shaft 35, and the bending column 32 is installed on the top of the rotating sleeve 36.

[0070] Specifically, the central shaft 35 and the rotating sleeve 36 are both located in the bending seat 34 , and the tops of both extend from the upper end of the bending seat 34 , so as to facilitate the installation of the fixing block 31 and the bending column 32 .

[0071] In order to drive the rotation of the rotating sleeve 36, a gear 37 is installed at the lower end of the rotating sleeve 36. A rack 38 is engaged with the outer side of the gear 37. The rack 38 is connected to the piston rod of the bending cylinder 39 located at the rear side thereof.

[0072] Specifically, the gear 37 is located in the bending seat 34 , and the piston rod of the bending cylinder 39 is connected to the rack 38 . The extension and retraction of the piston rod can drive the rack 38 to move forward and backward, thereby driving the rotation of the rotating sleeve 36 .

[0073] Preferably, a roller 310 cooperating with the rack 38 is provided on the side wall of the bending seat 34, which can increase the smoothness of the movement of the rack 38 and reduce friction.

[0074] In order to achieve the movement of the pressing block 33, the pressing block 33 is connected to the piston rod of the pressing cylinder 311 located at the rear side thereof.

[0075] Specifically, the piston rod of the pressing cylinder 311 is arranged forward and connected to the pressing block 33, thereby driving the pressing block 33 to cooperate with the fixing block 31 to achieve the pressing and loosening of the material strip.

[0076] Preferably, in order to guide the movement of the pressing block 33 , a guide seat 312 is installed between the pressing cylinder 311 and the fixed block 31 , and the pressing block 33 can slide in the guide seat 312 .

[0077] The material frame processed in this embodiment has a rectangular structure, and the four bending mechanisms 3 are arranged side by side in the left and right directions. The two bending mechanisms 3 located in the middle are used for bending the two inner corners of the material strip (the bending corners away from the end of the material strip), and the two bending mechanisms 3 located on the outside are used for bending the two outer corners of the material strip (the bending corners close to the end of the material strip), and all four corners are bent forward.

[0078] When bending, it is necessary to bend the outer corner first and then the inner corner. In order to prevent the fixed block 31 from blocking the material strip when bending the inner corner, a lifting cylinder II 313 connected to the piston rod and the center shaft 35 is installed under the bending seat 34 of the two bending mechanisms 3 on the outside. The lifting cylinder II 313 can drive the center shaft 35 to move up and down in the rotating sleeve 36.

[0079] Specifically, after the two bending mechanisms 3 located on the outside complete the bending of the two outer corners, the lifting cylinder II 313 drives the central shaft 35 and the fixed block 31 to move downward, so that they are retracted into the rotating sleeve 36. At this time, the two bending mechanisms 3 located in the middle can complete the bending operation of the two inner corners.

[0080] Preferably, the lifting cylinder II 313 is installed on a base plate 314 , and the base plate 314 is fixed to the bottom of the bending seat 34 through a plurality of screws 315 . The arrangement of the screws 315 can facilitate the adjustment of the position of the lifting cylinder II 313 .

[0081] The bottom of the central shaft 35 with the lifting cylinder II 313 is directly connected to the piston rod of the lifting cylinder II 313, while the bottom of the central shaft 35 without the lifting cylinder II 313 is directly fixed to the bottom of the bending seat 34 using a nut.

[0082] The number of bending mechanisms 3 is not limited to the four disclosed in this embodiment. The number can be set according to the bending requirements of the frame, and the angle and bending direction of each bending angle can be adjusted by the rotation angle and rotation direction of the bending column 32.

[0083] Preferably, in order to facilitate the adjustment of the rotation angle of the bending column to achieve control of the bending angle, the bending cylinder 39 uses a double-piston rod cylinder, the front end piston rod of which is connected to the rack 38, and the rear end piston rod is installed with a limit block 316. By adjusting the position of the limit block 316 to control the length of the front end piston rod extending, the rotation angle of the gear 37 is adjusted to achieve the effect of adjusting the bending angle.

[0084] Preferably, in order to adapt to the bending of material strips of different lengths, left and right guide rails Ⅱ54 are installed on the equipment frame 5, and a slider that cooperates with the guide rails Ⅱ54 is installed at the bottom of the bending seat 34. Through the cooperation of the guide rails Ⅱ54 and the sliders, the position of each bending mechanism 3 can be adjusted to adapt to the bending of frames of different specifications.

[0085] After the bending operation is completed, the two end points of the material strip are directly located in the butt welding mechanism 4, and the butt welding operation can be performed at this time.

[0086] The butt welding mechanism 4 further includes a fixing seat 41 , which is installed on the equipment frame 5 .

[0087] A protective cover 42 is installed on the front side of the butt welding mechanism 4, and a storage plate 43 is provided on the top.

[0088] In order to achieve welding of the two end points of the material strip, the welding mechanism 4 includes two pairs of electrode blocks 44 arranged oppositely in the front and rear. The two electrode blocks 44 arranged side by side on the front side can move up, down and backward synchronously, and the two oppositely arranged electrode blocks 44 on one side can move synchronously to the other side.

[0089] After bending, the front edge of the material strip is arranged horizontally, and the end of the material strip is located between the front electrode block 44 and the rear electrode block 44. The two electrode blocks 44 on the front side can move up and down. This is to prevent the two electrode blocks 44 from blocking the material strip when the two electrode blocks 44 move downward during bending, and move up again to face the two electrode blocks 44 on the rear side during butt welding, so as to facilitate the subsequent fixation of the end of the material strip.

[0090] The two electrode blocks 44 on the front side can be moved backward synchronously in order to cooperate with the two electrode blocks 44 on the rear side to clamp the ends of the material strip and fix the material strip.

[0091] The two front and rear facing electrode blocks 44 on the same side move synchronously toward the other side so as to bring the two end points of the material strip into contact and achieve butt welding after the electrode blocks 44 are connected to the power supply 55 .

[0092] In order to fix the two electrode blocks 44 on the front side, the two electrode blocks 44 on the front side are respectively fixed on the top of the two upper pressure arm electrode fixing plates 45.

[0093] Specifically, an electrode fixing block 46 is installed on the top of the upper pressure arm electrode fixing plate 45 , and the two electrode blocks 44 are respectively installed on the electrode fixing blocks 46 .

[0094] In order to drive the two electrode blocks 44 on the front side to swing backward and cooperate with the two electrode blocks 44 on the rear side to clamp the end of the material strip, the butt welding mechanism 4 also includes a support frame 47. A swing cylinder 48 is installed at the bottom of the support frame 47. The bottom of the upper pressure arm electrode fixing plate 45 is hinged to the piston rod of the swing cylinder 48. The upper pressure arm electrode fixing plate 45 is movably connected to the support frame 47 through the bracket plate 49. The swing cylinder 48 can drive the top of the upper pressure arm electrode fixing plate 45 to swing backward.

[0095] Specifically, the support frame 47 is an L-shaped structure, the upper pressure arm electrode fixing plate 45 is located on the front side of its vertical plate, and a cylinder fixing plate is provided below its horizontal plate. The piston rod of the swing cylinder 48 is set forward, and its tail is hinged to the cylinder fixing plate, and the front end of its piston rod is connected to the lower end of the upper pressure arm electrode fixing plate 45 through the hinge seat 410.

[0096] The bracket plate 49 can support the upper pressure arm electrode fixing plate 45. A strip hole is opened on the bracket plate 49. The upper pressure arm electrode fixing plate 45 is located between the two bracket plates 49, and the upper pressure arm electrode fixing plate 45 is installed with a shoulder screw 411 that fits in the strip hole. The shoulder screw 411 passes through the strip holes on the upper pressure arm electrode fixing plate 45 and the bracket plates 49 on both sides thereof.

[0097] The piston rod of the swing cylinder 48 extends to drive the top of the upper pressure arm electrode fixing plate 45 to swing backward, so that the front electrode block 44 approaches the rear electrode block 44, and when swinging, the shoulder screw 411 can follow the upper pressure arm electrode fixing plate 45 to move in the strip hole.

[0098] In order to achieve the lifting and lowering of the upper pressure arm electrode fixing plate 45, lifting cylinders III 412 are provided on both sides of the support frame 47. The lifting cylinders III 412 can drive the support frame 47 to move up and down.

[0099] The piston rod of the lifting cylinder is set upward, and the top of the piston rod is connected to the support frame 47 through the connecting plate 413. The two lifting cylinders II 313 act synchronously, driving the two support frames 47 and the upper pressure arm electrode fixing plate 45 to rise and fall synchronously.

[0100] In order to realize the installation of the two electrode blocks 44 on the rear side, the two electrode blocks 44 on the rear side are respectively installed on the top of the two conductive bars 414 . The welding mechanism 4 also includes a support plate 415 , and the conductive bars 414 are installed on the support plate 415 .

[0101] A power supply 55 is installed in the equipment rack 5 . The lower end of the conductive bar 414 is connected to a wiring bar 416 that passes through the fixing seat 41 backwards. The wiring bar 416 is connected to the power supply 55 via a copper braided wire to energize the electrode block 44 .

[0102] In order to enable one of the electrode blocks 44 located on the rear side to move toward the other electrode block 44, the support plate 415 on one side is connected to the piston rod of the translation cylinder 417 located on its outside, and the translation cylinder 417 can drive the support plate 415 connected thereto to move left and right.

[0103] The translation cylinder 417 is arranged transversely, with the side where it is located being the movable side of the butt welding mechanism 4 and the other side being the fixed side.

[0104] A transverse slide rail is provided on the fixed seat 41 , and a slider matching the slide rail is installed on the rear side of the support plate 415 on the movable side. The translation cylinder 417 drives the support plate 415 connected thereto to move transversely.

[0105] In order to make the two electrode blocks 44 on the movable side move synchronously toward the fixed side, the lifting cylinder III 412 located on the side where the translation cylinder 417 is located is fixed on the corresponding support plate 415.

[0106] The lifting cylinder III 412 located on the movable side is installed on the support plate 415 on this side, and can move laterally synchronously with the conductive bar 414 on the same side under the action of the translation cylinder 417.

[0107] The support plate 415 and the lifting cylinder III 412 on the fixed side are directly fixed on the fixing seat 41 .

[0108] In order to guide the lifting and lowering of the support frame 47, a vertical slide rail is set on the front side of the support plate 415, and a slider that cooperates with the slide rail is set on the rear side of the support frame 47. The guidance of the support frame 47 during lifting and lowering is achieved through the cooperation of the slide rail and the slider.

[0109] Preferably, two proximity switches II418 mounted on the fixed seat 41 are provided on the outer side of the lifting cylinder III412 located on the fixed side, which can detect and limit the extension and contraction amount of the piston rod of the lifting cylinder III412, that is, the lifting degree of the upper pressure arm electrode fixing plate 45.

[0110] In order to prevent the two end points of the frame from being misaligned upward or downward during welding and ensure the welding effect, positioning plates 419 are respectively provided on the outside of the conductive bar 414 and between the two conductive bars 414, and a V-shaped positioning hole is opened at the front end of the positioning plate 419.

[0111] The front frame of the welding part is located in the positioning hole so that both ends are located in the same horizontal plane, ensuring the accuracy during welding.

[0112] In order to prevent the positioning plate 419 from obstructing the butt welding process, a positioning cylinder 420 is connected to the rear end of the positioning plate 419 located between the two conductive bars 414 to drive the positioning plate 419 to move forward and backward.

[0113] The positioning cylinder 420 is fixed to the rear side of the fixing base 41 through a mounting bracket.

[0114] Since the frames have different specifications, the positions of the two end points are not fixed during butt welding. In order to be able to adjust the position of the butt welding mechanism 4 as needed, a guide rail seat I56 is provided at the bottom, and a transverse guide rail III57 is installed on the guide rail seat I56. The transverse adjustment screw I58 is used to realize the transverse movement of the butt welding mechanism 4 on the guide rail III57.

[0115] A guide rail seat II 59 is provided below the guide rail seat I 56 , and a longitudinal guide rail IV 510 is installed on the guide rail seat II 59 . The longitudinal movement of the guide rail seat II 59 and the welding mechanism 4 is achieved through the longitudinal adjustment screw II 511 .

[0116] When processing the material frame, first adjust the positions of the baffles at both ends of the material trough 1, the positions of the four bending mechanisms 3, and the positions of the butt welding mechanism 4 according to the specifications of the processed frame. After the material strips are placed in the material trough 1, the feeding mechanism absorbs the material strips one by one and feeds them into the bending mechanism 3. The four bending mechanisms 3 bend the material strips. After bending is completed, the two end points of the material strip are located at the two pairs of electrode blocks 44 of the butt welding mechanism 4. At this time, the two end points are contacted and butt welded using the butt welding mechanism 4, and the frame processing is completed.

[0117] The present invention completes the loading, bending and butt welding of the frame on the same device, which not only improves the integration level of the equipment and the high degree of automation, but also ensures the processing quality of the frame and improves the processing efficiency of the frame.

[0118] With the above-described preferred embodiments of the present invention as a guide, and with reference to the above description, relevant personnel are fully capable of making various changes and modifications without departing from the technical scope of this invention. The technical scope of this invention is not limited to the contents of the specification and must be determined according to the scope of the claims.
