DETAILED DESCRIPTION

[0036] Embodiments of the present application are described in detail below with reference to the attached drawing figures, wherein the same or like component have the same or similar designations. The embodiments described below are exemplary in nature, and are intended to be illustrative of the present application rather than to limit the same.

[0037] For a better understanding of the above technical solutions, the exemplary embodiments of the present application will be described in more detail below with reference to the attached drawings. Although the exemplary embodiments of the present application are shown in the drawings, it should be understood that the present application can be implemented in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided so that the present application can be more thoroughly and completely conveyed to those skilled in the art.

[0038] The bending machine 1 according to the embodiment of the present application is described in detail below with reference to the attached drawings.

[0039] It should be noted that the control system in the present embodiment is programmed through the control panel. Since the programmable control system is prior art, it is not described in detail herein.

[0040] Referring to Figures 1-8 , the bending machine 1 in the embodiment of the present application is shown. The bending machine 1 is used for automatic bending processing of busbars and the like workpieces, wherein the workpieces are taken as busbars for example. Generally, the busbar needs to be bent at an angle in the length direction thereof, so in the bending machine 1, the busbar is conveyed and bent in a transversely upright state. The bending machine 1 according to the embodiment of the present application can realize feeding, positioning of bending position, and full-automatic bending of busbars of various sizes, and can also automatically adjust the feeding position of the busbar to realize flexible full-automatic bending processing of the busbar. The bending machine 1 comprises a feeding device 10, a transition clamping device 20, a clamping device 30, a bending device 40, and a discharge conveying line 50 arranged in sequence. Understandably, the feeding device 10, the transition clamping device 20, the clamping device 30, the bending device 40, and the discharge conveying line 50 are arranged in the order of feeding, conveying, bending, and the like processing of the busbar, so that the bending machine 1 has a series of automatic action processes such as automatic feeding, automatic bending, and automatic discharge.

[0041] Specifically, referring to Figures 2-4 , the feeding device 10 has a first moving part 11 and two roller shaft groups 12, the two roller shaft groups 12 are oppositely arranged and connected with the first moving part 11, and the first moving part 11 is used to drive the two roller shaft groups 12 to move towards each other to define a channel for conveying the busbar. In this way, through the movement of the two roller shafts 12 towards each other, the channel for conveying the busbar can be flexibly adjusted in centering according to the thickness parameter of the busbar, and the feeding position is always adjusted to be centered, so as to automatically adjust the feeding position of the busbar.

[0042] The two roller shaft groups 12 can include a driving roller shaft group 121, a passive roller shaft group 122 and a first motor 123. The driving roller shaft group 121 is powered by the first motor 123, and each roller shaft in the driving roller shaft group 121 is driven to rotate by a gear transmission structure. It can be understood that the two roller shaft groups 12 are arranged side by side by a plurality of roller shafts, and are installed to form the roller shaft group 12 by a support 124. The support 124 is installed on the first moving part 11, so that the two roller shaft groups 12 are connected to the first moving part 11. The first moving part 11 can include a bidirectional screw rod 111 and a second motor 112 for driving the bidirectional screw rod 111 to rotate. One of the two roller shaft groups 12 (for example, the driving roller shaft group 121) is connected to the positive threaded end of the bidirectional screw rod 111, and the other roller shaft group (for example, the passive roller shaft group 122) is connected to the reverse threaded end of the bidirectional screw rod 111. In this way, the bidirectional screw rod 111 can move the two roller shaft groups 12 towards each other under the drive of the second motor 123. It can be understood that the second motor 123 drives the bidirectional screw rod 111 to rotate, and the bidirectional screw rod 111 drives the two roller shaft groups 12 at the positive and reverse threaded ends to move towards each other to center and clamp the busbar. When the two roller shaft groups 12 clamp the busbar, the first motor 123 drives the driving roller shaft group 121 to rotate, so that the driving roller shaft group 121 and the passive roller shaft group 122 jointly drive the busbar to move to the next station.

[0043] Further, the bidirectional screw rod 111 can be a first trapezoidal screw rod. The first trapezoidal screw rod has self-locking property, which can ensure stable centering and clamping of the busbar. In addition, the first moving part 11 can further include a first sliding guide rod 113, which is arranged parallel to the bidirectional screw rod 111 and is slidably connected to the two roller shaft groups 113. Thus, the bidirectional screw rod 111 has stability when driving the two roller shaft groups 12 to move.

[0044] Please refer to Figure 2 and Figure 5 The transition clamping device 20 has a first clamp 21 and a second moving part 22. The first clamp 21 is connected to the second moving part 22, and the second moving part 22 is used to drive the first clamp 21 to move back and forth between the feeding device 10 and the clamping device 30 to transport the busbar. In this way, by the transition setting of the transition clamping device 20 between the feeding device 10 and the clamping device 30, the busbar of a relatively short size can be transported from the feeding device 10 to the clamping device 30. At the same time, the busbar clamped by the transition clamping device 20 can also push the finished product after bending in the clamping device 30 out of the bending device 40 and into the discharge conveying line 50.

[0045] The first clamp 21 can include two clamping plates 211 and two cylinders 212. The two clamping plates 211 are arranged opposite to each other and are connected to the two cylinders 212 one by one. The two cylinders 212 are used to drive the two clamping plates 211 to move to clamp or release the busbar. It can be understood that the two cylinders 212 drive the two clamping plates 211 to move towards each other to clamp the busbar, and move in the opposite direction to release the busbar. In this way, the first clamp 21 composed of the two cylinders 212 and the two clamping plates 211 can be flexibly centered and clamped according to the thickness parameter of the busbar. In the embodiment, the cylinder 212 can be a double-shaft cylinder, which can make the two clamping plates 211 flexibly and stably clamp the busbar according to the thickness parameter of the busbar.

[0046] In addition, the second moving part 22 can include a mounting plate 221 and a second trapezoidal screw rod 222 and a second sliding guide rod 223 arranged parallel to each other. One side of the mounting plate 221 is connected to the second trapezoidal screw rod 222, and the other side is connected to the second sliding guide rod 223. The second trapezoidal screw rod 222 is used to drive the mounting plate 221 to slide on the second sliding guide rod 223. The first clamp 21 is arranged on the mounting plate 221. It can be understood that the second moving part 22 can be integrally installed on the first mounting seat 23, wherein the side surface of the mounting plate 221 is in sliding connection with the first mounting seat 23. In this way, the second trapezoidal screw rod 222 can drive the mounting plate 221 to slide on the second sliding guide rod 223 under the drive of the third motor 224, so that the first clamp 21 on the mounting plate 221 can clamp the busbar to move along the second sliding guide rod 223, thereby enabling the first clamp 21 to move back and forth between the feeding device 10 and the clamping device 30 to transport the busbar.

[0047] Please refer to Figure 2 , Figure 6 and Figure 7 , the clamping device 30 has a second clamp 31, which clamps the busbar at the position where the busbar is to be bent to make the part to be bent on the busbar pass through the second clamp 31. The bending device 40 includes a bending die rod 41 and a third moving part 42. The bending die rod 41 is used to feed towards the busbar to apply a force to the part to be bent on the busbar, so that the part to be bent on the busbar is bent at an angle relative to the clamping position. The third moving part 42 is connected to the bending die rod 41 to drive the bending die rod 41 to feed. In this way, the position of the busbar to be bent is positioned by the clamping device 30, and the busbar is clamped at the position to be bent. The bending device 40 applies a force to the part to be bent on the busbar, and the second clamp 31 clamps the busbar at the position to be bent, so that the part to be bent on the busbar is bent at an angle relative to the clamping position, thereby realizing the bending processing of the busbar.

[0048] The second clamp 31 can include a second mounting base 311, a first hydraulic cylinder 312, two wedge blocks 313, and a first sliding block 314 mounted in the second mounting base 311, the first sliding block 314 being provided with a wedge-shaped groove 3141, the inclined surfaces of the two wedge blocks 313 being slidably connected to the inclined surfaces of the wedge-shaped groove 3141, and the two wedge blocks 313 being oppositely arranged to define a clamping opening 315; the first hydraulic cylinder 312 is connected to the first sliding block 314 to drive the first sliding block 314 to slide in the second mounting base 311, and the first sliding block 314 drives the two wedge blocks 313 to slide on the wedge-shaped groove 3141 to open or close the clamping opening 315. Understandably, due to the limitation of the second mounting base 311, when the piston rod of the first hydraulic cylinder 312 extends upward, the first sliding block 314 moves upward, and the two wedge blocks 313 move towards each other to clamp the busbar; when the piston rod of the first hydraulic cylinder 312 retracts downward, the first sliding block 314 moves downward, and the two wedge blocks 313 move in the opposite direction to release the busbar. In this way, the second clamp 31 uses the two wedge block structures to make the clamp structure compact, the force amplification ratio large, and the clamping force generated large; in addition, the clamping of the two wedge blocks 313 can be flexibly adjusted according to the thickness of the busbar, and when the two wedge blocks 313 move towards each other to tightly abut against each other, the two wedge blocks 313 have a material blocking effect on the busbar that has not been clamped by the clamping device 30; in this way, when the busbar is blocked and released, the system can start to detect and collect the length of the movement of the busbar, so as to automatically control the two wedge blocks 313 to clamp the busbar at the bending position, and realize the automatic positioning and bending of the busbar.

[0049] Further, the clamping device 30 further comprises a fourth moving component 32 connected with the second clamp 31 to drive the second clamp 31 to move close to or away from the bending device 40. In this way, the distance between the second clamp 31 and the rear bending device 40 can be flexibly adjusted according to the thickness of the busbar, so that busbars with different thicknesses can be effectively bent by the bending machine 1. In the embodiment, the fourth moving component 32 can comprise a third trapezoidal screw 321 and a third sliding guide rod 322 arranged in parallel with each other, one side of the second mounting seat 311 is connected with the third trapezoidal screw 321, and the other side is connected with the third sliding guide rod 322, and the third trapezoidal screw 321 is used to drive the second mounting seat 311 to slide on the third sliding guide rod 322. It can be understood that the fourth moving component 32 can be integrally installed on the support seat 33, wherein the side surface of the second mounting seat 311 is in sliding connection with the support seat 33; in this way, the third trapezoidal screw 321 can drive the second mounting seat 311 to slide on the third sliding guide rod 322 under the drive of the fourth motor 323, so that the two wedge-shaped blocks 313 on the second mounting seat 311 can clamp the busbar to move along the third sliding guide rod 322, thereby flexibly adjusting the distance between the second clamp 31 and the rear bending device 40 according to the thickness of the busbar, so that busbars with different thicknesses can be effectively bent by the bending machine 1.

[0050] In addition, in combination with Figure 1 , the feeding device 10, the transition clamping device 20, and the clamping device 30 can be arranged transversely, so that the busbar is pushed in the transverse direction; and the bending device 40 can be arranged longitudinally, so that the bending die rod 41 can be fed longitudinally to apply a force to the part of the busbar to be bent. The third moving component 42 can comprise a second hydraulic cylinder 421, a guide rail 422, and a second sliding block 423, the bending die rod 41 is vertically arranged on the second sliding block 423, the second sliding block 423 is in sliding connection with the guide rail 422, and the second hydraulic cylinder 421 is connected with the second sliding block 423 to drive the second sliding block 423 to reciprocate on the guide rail 422, so that the bending die rod 41 is fed. It can be understood that by controlling the stroke of the second hydraulic cylinder 421, the longitudinal movement of the bending die rod 41 can be controlled, thereby bending the busbar; the extension degree of the second hydraulic cylinder 421 can adjust the bending angle of the busbar required by the bending die rod 41. In this way, the busbar is clamped at the position to be bent by the clamping device 30, and the part to be bent of the busbar is fed by the bending device 40, so that the busbar is bent.

[0051] Further, to improve the versatility of the bending machine 1, in the present embodiment, the bending device 40 further comprises a lifting driving assembly 43 connected to the bending die bar 41 to drive the bending die bar 41 to move up and down between a first height position and a second height position, when the bending die bar 41 is located at the first height position, the third moving component 42 drives the bending die bar 41 to feed, when the bending die bar 41 is located at the second height position, the third moving component 42 drives the bending die bar 41 to move from the first side A of the busbar to be bent to the second side B, the first side A and the second side B are opposite. Specifically, the lifting driving assembly 43 can comprise a rack 431 arranged on the bending die bar 41, a gear 433 arranged on the fifth motor 432; so that the fifth motor 432 drives the rotation of the gear 433, in turn drives the movement of the rack 431, so that the bending die bar 41 moves up and down between the first height position and the second height position. It can be understood that when the bending die bar 41 is at the first side A and the second side B of the busbar needs to be bent at an angle, the lifting driving assembly 43 drives the bending die bar 41 to move to the first height position, and then the third moving component 42 drives the bending die bar 41 to feed to the first side A of the busbar, so that the busbar is bent at an angle to the second side B. When the bending die bar 41 is at the first side A and the first side A of the busbar needs to be bent at an angle, the lifting driving assembly 43 drives the bending die bar 41 to move to the second height position, then the third moving component 42 drives the bending die bar 41 to move to the second side B, then the lifting driving assembly 43 drives the bending die bar 41 to move to the first height position, finally, the third moving component 42 drives the bending die bar 41 to feed to the second side B of the busbar, so that the busbar is bent at an angle to the first side A. In this way, the design requirement that the front and back of the busbar can be bent can be realized, and various types of busbars can be bent and processed.

[0052] Please refer to Figure 1 and Figure 8The discharge conveying line 50 comprises a universal ball conveyor 51 and a lifting and pushing device 52. The universal ball conveyor 51 has a universal ball group 511, a supporting plate 512 and a linear motor 513. The supporting plate 512 is swingably arranged on the universal ball group 511 to receive the busbar after being processed by the bending device 40. The linear motor 513 is connected to the supporting plate 512 through a first connecting plate 514. It can be understood that, after the busbar is bent, the busbar is pushed onto the supporting plate 512. Due to the action of the universal ball group 511 under the supporting plate 512, the supporting plate 512 swings and moves longitudinally according to the left and right shaping of the busbar during bending. In addition, the lifting and pushing device 52 is arranged beside the universal ball conveyor 51 to push the busbar on the supporting plate 512 into a finished product collecting area, facilitating the collection and classification of the finished product. It can be understood that the lifting and pushing device 52 comprises a pushing piece 521, a pushing cylinder 522 and a lifting cylinder 523. The pushing piece 521 is connected to the piston rod of the pushing cylinder 522. The busbar on the supporting plate 512 is pushed into the finished product collecting area by the extension and retraction of the piston rod of the pushing cylinder 522. The lifting cylinder 523 is connected to the pushing cylinder 522 through a second connecting plate 524 to drive the lifting and lowering movement of the pushing cylinder 522. In this way, the pushing piece 521 and the pushing cylinder 522 can be lifted during work and lowered during non-work, so that the busbar is not interfered by the pushing piece 521 in space during bending.

[0053] In this way, the discharge conveying line 50 enables the bending machine 1 to convey the processed busbar to the finished product collecting area, thereby realizing the automatic bending processing of the busbar by the bending machine 1.

[0054] In this way, the bending machine 1 realizes the automatic bending processing of the busbar by the cooperation of the feeding device 10, the transition clamping device 20, the clamping device 30, the bending device 40 and the discharge conveying line 50. The first moving part 11 drives the two roller shaft groups 12 to move towards each other, so that the channel defined by the two roller shaft groups 12 can be flexibly centered and adjusted according to the thickness parameter of the busbar, thereby automatically adjusting the feeding position. The second moving part 22 drives the first clamp 21 to convey the busbar, so that the bending machine 1 is suitable for processing busbars of various sizes. The clamping device 30 and the bending device 40 realize the automatic bending operation of the busbar. The transition clamping device 20 and the discharge conveying line 50 realize the automatic discharge of the processed busbar to the finished product collecting area.
