[0034] Reference below Figures 1 to 4 The bending device of the present application is described in detail.
[0035] refer to Figure 1 According to an embodiment of the present invention, the bending device includes a frame, a driving structure 100 and a flipping structure 200.
[0036] For example, Figures 1 to 3 As shown, the workpiece 20 is conveyed from front to back so that the preset moving path 10 of the workpiece 20 extends from front to back. The lower side of the preset moving path 10 of the workpiece 20 is the first side 11, and the upper side of the preset moving path 10 of the workpiece 20 is the second side 12. The workpiece 20 includes a main body 22 and a handle 21. The front end of the main body 22 is connected to the handle 21. The bending device of the present application is used to turn the handle 21 toward the upper side of the main body 22. The bending process of the handle 21 is as shown in FIG. Figure 2The driving structure 100 is arranged on the rack and located at the lower side of the preset moving path 10 of the workpiece 20, and the turnover structure 200 is arranged on the rack and located at the upper side of the preset moving path 10 of the workpiece 20.
[0037] It can be understood that when the bending device of the application works, the workpiece 20 can move to the upper side of the driving structure 100 along the preset moving path 10, and under the action of the driving structure 100, the handle 21 can be turned up by a certain angle, so that the turnover structure 200 is located on the moving path of the turned handle 21, and then, as the workpiece 20 continues to move along the preset moving path 10, the handle 21 can abut against the turnover structure 200, in this case, as the workpiece 20 continues to move backward along the preset moving path 10, the handle 21 cannot continue to move backward under the abutment of the turnover structure 200, and the main body 22 can continue to move backward, so that the handle 21 can continue to turn backward until the handle 21 is turned and bent to the upper side of the main body 22.
[0038] Further, in the bending device of the application, through the cooperation of the driving structure 100 and the turnover structure 200, the handle 21 on the workpiece 20 can be automatically turned and bent to the upper side of the main body 22 during the movement of the workpiece 20 along the preset moving path 10, and the bending device of the application can automatically complete the bending of the handle 21 on the workpiece 20, thereby reducing the labor intensity of the workers and saving time and effort.
[0039] In some embodiments of the application, the driving structure 100 includes an elastic bending piece 110, the elastic bending piece 110 includes a first connecting end 111 and a first movable end 112 arranged opposite to each other, the first connecting end 111 is connected with the rack and located at the first side 11, and the first movable end 112 extends to the second side 12, when the handle 21 moves to abut against the first movable end 112, the handle 21 can be turned to the second side 12 by a certain angle under the counter-push of the first movable end 112, and when the main body 22 moves to abut against the first movable end 112, the first movable end 112 can overcome the elastic force of the elastic bending piece 110 itself and move to the first side 11 to avoid the main body 22 under the push of the main body 22.
[0040] For example, as shown in FIG. 6, the handle 21 is turned and bent to the upper side of the main body 22, and the handle 21 is located on the moving path of the turnover structure 200. Figure 3As shown, the upper end of the elastic bending member 110 is the first movable end 112, the lower end of the elastic bending member 110 is the first connecting end 111, and the first connecting end 111 is connected to the frame. Under the action of external force, the elastic bending member 110 can be deformed so that the first movable end 112 can move downward; the first connecting end 111 is located on the lower side of the preset moving path 10 of the workpiece 20, and the first movable end 112 extends upward to the upper side of the preset moving path 10 of the workpiece 20.
[0041] It can be understood that in the process of the workpiece 20 moving from front to rear along the preset moving path 10, since the first movable end 112 of the elastic bending member 110 extends upward to the upper side of the preset moving path 10 of the workpiece 20, the handle 21 of the workpiece 20 can first abut against the elastic bending member 110. As the main body 22 of the workpiece 20 continues to move backward, the handle 21 of the workpiece 20 is pushed back by the elastic bending member 110, and the handle 21 flips upward and tilts up a certain angle until the main body 22 of the workpiece 20 abuts against the elastic bending member 110. Then, the main body 22 of the workpiece 20 can push the elastic bending member 110 downward and cause the elastic bending member 110 to deform until the first movable end 112 of the elastic bending member 110 moves downward to the bottom of the preset moving path 10 of the workpiece 20. At this time, the elastic bending member 110 avoids the main body 22 so that the main body 22 can move backward smoothly.
[0042] It can be understood that the elastic bending member 110 has a simple structure and is easy to implement.
[0043] In order to make the elastic bending member 110 more smoothly turn the handle 21 upward to a certain angle, and to make the main body 22 more smoothly press the elastic bending member 110 downward to deform, in a further embodiment of the present invention, reference is made to Figure 3 , along the extension direction of the preset moving path 10 , the first movable end 112 is located at the rear side of the first connecting end 111 .
[0044] It should be noted that, since the first movable end 112 is located above and behind the first connecting end 111, the upper surface of the elastic bending part 110 can form a guide surface 113 extending rearward and upward. During the movement of the workpiece 20 from front to back along the preset moving path 10, when the handle 21 of the workpiece 20 touches the guide surface 113, under the guidance of the guide surface 113, the handle 21 moves rearward and upward along the guide surface 113, thereby realizing that the handle 21 is flipped upward by a certain angle relative to the main body 22. When the main body 22 of the workpiece 20 touches the guide surface 113, under the abutment of the main body 22, the elastic bending part 110 bends and deforms downward to avoid the main body 22, so that the main body 22 can pass smoothly.
[0045] It can be understood that, along the extension direction of the preset moving path 10, by arranging the first movable end 112 at the rear side of the first connecting end 111, the handle 21 can be smoothly turned to the second side 12 by a certain angle under the abutting of the elastic connecting piece, and the elastic bending piece 110 can be more smoothly deformed to the first side 11 under the abutting of the main body part 22, so that the elastic bending piece 110 can smoothly avoid the main body part 22.
[0046] In some embodiments of the utility model, the driving structure 100 can also include a driver and a thrust piece, the driver is connected with the thrust piece, and is used for driving the thrust piece to make lifting movement. Further, when the handle 21 moves to the upper side of the thrust piece, the driver can drive the thrust piece to move upward, so that the thrust piece pushes the handle 21 to turn upward by a certain angle, and then the driver can drive the thrust piece to move downward, so that the thrust piece avoids the main body part 22.
[0047] In some embodiments of the utility model, the turning structure 200 includes opposite second connecting end 211 and second movable end 231, second connecting end 211 is connected with the rack, and second movable end 231 is used for abutting with the handle 21, and the distance between second movable end 231 and preset moving path 10 is less than the distance between first movable end 112 and preset moving path 10.
[0048] For example, as shown in Figure 3 The turning structure 200 includes the second connecting end 211 at the upper end and the second movable end 231 at the lower end, the second movable end 231 is located on the upper side of the preset moving path 10 of the workpiece 20, and the second movable end 231 is located on the lower side of the first movable end 112, so that the vertical distance between the second movable end 231 and the preset moving path 10 is less than the distance between the first movable end 112 and the preset moving path 10.
[0049] It can be understood that, since the second movable end 231 is located on the lower side of the first movable end 112, but after the handle 21 is turned upward by a certain angle under the action of the elastic bending piece 110, the upper end of the handle 21 can be located above the second movable end 231, so that the second movable end 231 can smoothly fall into the preset moving path 10 of the turned handle 21, and further, the turning structure 200 can smoothly abut with the handle 21 subsequently.
[0050] In some embodiments of the utility model, referring to Figure 3 The turning structure 200 includes the connecting section 210, the elastic section 220 and the abutting section 230 connected in sequence, one end of the connecting section 210 away from the elastic section 220 forms the second connecting end 211, and one end of the abutting section 230 away from the elastic section 220 forms the second movable end 231.
[0051] It can be understood that the elastic section 220 is arranged so that when the turnover structure 200 abuts against the handle 21, not only can the handle 21 be turned and bent onto the main body portion 22 under the abutment of the turnover structure 200, but also the turnover structure 200 can be elastically deformed under the pushing of the handle 21, so that the turnover structure 200 can avoid the handle 21, thereby enabling the workpiece 20 to smoothly move along the preset movement path 10.
[0052] In further embodiments of the present application, the extension direction of the connecting section 210 is perpendicular to the extension direction of the preset movement path 10, the extension direction of the abutment section 230 is parallel to the extension direction of the preset movement path 10, and along the extension direction of the preset movement path 10, the second movable end 231 is located on the front side of the elastic section 220.
[0053] For example, as shown in Figure 3 The connecting section 210 is arranged to extend in the vertical direction, the abutment section 230 is arranged to extend in the front-rear direction, one end of the elastic section 220 is connected to the lower end of the connecting section 210, and the other end of the elastic section 220 is connected to the rear end of the abutment section 230, so that the turnover structure 200 as a whole presents a hook shape.
[0054] It can be understood that when the workpiece 20 moves backward to the turnover structure 200, the handle 21 on the workpiece 20 can first abut against the front end of the abutment section 230, and under the abutment of the abutment section 230, the handle 21 can be turned and bent backward, and at the same time, since there is a certain gap between the abutment section 230 and the preset movement path 10 of the workpiece 20, the main body portion 22 of the workpiece 20 can smoothly pass from the underside of the abutment section 230.
[0055] It can be understood that since the turnover structure 200 as a whole presents a hook shape, after the workpiece 20 approaches the turnover structure 200, the turnover structure 200 can hook the handle 21 firmly, so as to reduce the probability that the handle 21 and the abutment section 230 slip and the bending angle of the handle 21 does not meet the standard.
[0056] It should be noted that although the cooperation of the bending structure and the turnover structure 200 can enable the handle 21 to be turned and bent onto the main body portion 22, the bent handle 21 still has the possibility of rebounding, and if the bent handle 21 rebounds, the bending angle of the handle 21 will not meet the standard.
[0057] Based on the above problems, in some embodiments of the present application, reference is made to Figure 1 and Figure 4The bending device further comprises a pressing plate 300 arranged at the second side 12 of the preset moving path 10, the pressing plate 300 is arranged close to the end face of the preset moving path 10 to form a limiting face 310 for abutting against the handle 21, and along the extension direction of the preset moving path 10, the pressing plate 300 is arranged at the rear side of the overturning structure 200, and the distance between the limiting face 310 and the preset moving path 10 gradually decreases.
[0058] It can be understood that, along the extension direction of the preset moving path 10, since the distance between the limiting face 310 and the preset moving path 10 gradually decreases, the bending angle of the handle 21 can gradually increase during the movement of the workpiece 20 along the preset moving path 10 under the abutment of the limiting face 310.
[0059] In order to enable the handle 21 after overturning and bending to be kept in the bent state, in some embodiments of the utility model, referring to Figure 1 The bending device further comprises a first pressing rod 400 arranged at the second side 12 of the preset moving path 10, along the extension direction of the preset moving path 10, the first pressing rod 400 is arranged at the rear side of the overturning member, and the first pressing rod 400 is used for keeping pressure on the handle 21 to enable the handle 21 to be kept bent on the main body part 22.
[0060] It can be understood that, by arranging the first pressing rod 400, the first pressing rod 400 can keep pressure on the handle 21, so that the bending angle of the handle 21 can be kept within a preset angle range, thereby reducing the probability of rebound of the handle 21.
[0061] In further embodiments of the utility model, referring to Figure 1 Figure 1 The bending device further comprises a second pressing rod 500 arranged at the second side 12 of the preset moving path 10, along the extension direction of the preset moving path 10, the second pressing rod 500 is arranged at the rear side of the first pressing rod 400, and the distance between the second pressing rod 500 and the preset moving path 10 is smaller than the distance between the first pressing rod 400 and the preset moving path 10.
[0062] It can be understood that, along the extension direction of the preset moving path 10, since the second pressing rod 500 is arranged at the rear side of the first pressing rod 400, and the distance between the second pressing rod 500 and the preset moving path 10 is smaller than the distance between the first pressing rod 400 and the preset moving path 10, the second pressing rod 500 can cooperate with the first pressing rod 400 to gradually keep pressure on the handle 21, so as to gradually increase the bending angle of the handle 21, thereby deepening the crease between the handle 21 and the main body part 22, and further reducing the probability of rebound of the handle 21.
[0063] In some embodiments of the utility model, the bending device further comprises a conveying structure, and the conveying structure is used for conveying the workpiece 20 to move along the preset moving path 10.
[0064] It should be noted that the conveying structure comprises a conveying roller set, the workpieces 20 are arranged on the material belt in the front-rear direction at intervals, and the material belt is provided with a hollow hole corresponding to the position of the handle 21, the hollow hole allows the elastic bending piece 110 to pass through, and the conveying roller set drives the material belt to move in the front-rear direction, thereby realizing the movement of the workpieces 20 on the material belt in the front-rear direction.
[0065] Although the embodiments of the utility model have been shown and described, those skilled in the art can understand that various changes, modifications, replacements and variations can be made to these embodiments without departing from the principles and purposes of the utility model, and the scope of the utility model is defined by the claims and their equivalents.
