Description

Technical Field

[0001] The present invention relates to the technical field of aluminum product bending equipment, and particularly relates to a bending device for processing aluminum products. Background Art

[0002] Aluminum products are a general term for daily necessities and industrial products processed mainly from aluminum alloy. Since the aluminum material itself is relatively soft and convenient for bending, when processing some aluminum products, raw materials such as aluminum bars and aluminum plates are often bent. For example, the frames of aluminum doors and windows, cabinets or suitcases generally need to be bent into a square frame.

[0003] When the existing aluminum product bending equipment needs to bend a long aluminum plate into a square frame, it generally relies on a pair of roller shafts evenly distributed at equal intervals to clamp the long aluminum plate for conveying, and conveys it towards the position of the bending mechanism. Whenever a point of the long aluminum plate is conveyed to the position of the bending mechanism, the bending mechanism is relied on to squeeze the long aluminum plate to make it bend, and it is bent continuously for multiple times, so that the long aluminum plate is bent into the shape of a square frame, then it is cut off and taken down, and the head and tail ends are welded together, and then subsequent processing operations are carried out.

[0004] The deficiencies of the existing aluminum product bending equipment are as follows: Although the existing aluminum product bending equipment can bend the long aluminum plate into the required frame structure, generally when bending into a polygonal frame, such as bending the long aluminum plate into a square frame, it needs to be bent continuously for multiple times, that is, the long aluminum plate is first conveyed a certain length beyond the position of the bending mechanism, and then the bending mechanism is relied on to perform a bending operation on the current aligned position, and then the long aluminum plate is conveyed forward a certain distance, and the bending mechanism is relied on to bend the next position, that is, it is necessary to repeatedly convey the long aluminum plate and perform the bending operation of the bending mechanism for multiple times. The operation is not convenient enough, and the processing time is relatively long, resulting in a relatively low overall bending processing efficiency. Summary of the Invention

[0005] The purpose of the present invention is to provide a bending device for processing aluminum products, so as to solve the technical problems that the existing aluminum product bending equipment needs to perform multiple bending operations when bending an aluminum frame, the operation is not convenient enough, the processing time is relatively long, and the overall bending processing efficiency is relatively low.

When the first driven gear drives the bending wheel group 1 to deflect, the rolling transmission mechanism rolls along the surface of the support base and drives the second driven gear to rotate.

[0012] As a further scheme of the present invention: The rolling transmission mechanism includes a wheel frame, a roller, a steering gear group and a second driving gear. The wheel frame is connected to the second support column. A side frame is fixedly connected to one side of the wheel frame. The roller is rotatably connected to the side frame. The second driving gear meshes with one side of the second driven gear and the second driving gear is rotatably connected to the wheel frame.

[0014] As a further solution of the present invention: The structure of the second bending wheel group is the same as that of the first bending wheel group, and the second support column corresponding to the second bending wheel group is fixedly connected to the second driven gear corresponding to the first bending wheel group. One side of the second support column corresponding to the first bending wheel group is fixedly connected with an arc guide plate, and the roller corresponding to the second bending wheel group contacts the arc guide plate.

[0015] As a further solution of the present invention: A strip-shaped chute is provided on the second support column. One end of the wheel frame is slidably connected in the strip-shaped chute.

The limiting guide wheels corresponding to the first bending wheel group, the limiting guide wheels corresponding to the second bending wheel group, and each of the rotating wheels have the same structure, and each includes a wheel body and a convex ring distributed at the bottom of the wheel body.

[0019] The beneficial effects of the present invention:

[0020] 1. The present invention relies on four-point positioning of the first positioning wheel, the second positioning wheel, the first bending wheel group, and the second bending wheel group for aluminum frame bending processing. The first driven gear at the position of the second positioning wheel drives the first bending wheel group and the corresponding push plate to deflect. The deflected push plate squeezes and bends the long strip aluminum plate at the first point. During the deflection of the first bending wheel group, the corresponding second driven gear rotates simultaneously, driving the corresponding push plate and the second bending wheel group to deflect. The push plate at this position causes the long strip aluminum plate to have a second point bending. During the deflection of the second bending wheel group, the corresponding second driven gear rotates simultaneously, and drives the corresponding push plate to cause a third point bending of the long strip aluminum plate, that is, multiple point bends are generated simultaneously in the same rotation direction, quickly bending and forming, without bending each position one by one, improving the bending processing efficiency.

[0021] 2. In the present invention, when the first driven gear is driven to rotate by the cooperation of the first driving gear and the first servo motor, the bending wheel group 1 is deflected relative to the positioning wheel 2, and the roller corresponding to the bending wheel group 1 rolls along the surface of the support seat, and the corresponding second driven gear is driven to rotate by the steering gear group and the corresponding second driving gear, so that the push plate rotates to bend the long aluminum plate. When the second driving gear of the bending wheel group 1 is deflected, it drives the bending wheel group 2 to deflect, and the roller corresponding to the bending wheel group 2 rolls along the arc guide plate, so that the corresponding second driven gear is driven to rotate by the corresponding steering gear group and the corresponding second driving gear, so that the push plate rotates to bend the long aluminum plate, that is, the push plate deflection and bending operations at different positions do not need to be driven by the driving source respectively, and do not need to be controlled separately, and only the driving source of the first driven gear needs to be started, and the operation is convenient and effective.

[0022] 3. When there is no need to bend multiple points, the present invention can manipulate the adjusting screw on the second support column corresponding to the bending wheel group to make the corresponding wheel frame slide and rise, thereby making the corresponding roller rise and leave the support point, making it impossible to transmit.

Detailed implementation mode

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0031] As Figures 1 - 5 shown, a bending device for aluminum product processing is used to bend a square aluminum frame. Generally, a square aluminum frame is used for the frame of aluminum doors and windows or the frame of a cabinet, and some luggage frames also use a bent square aluminum frame as the skeleton. The bending device includes a support base 1 and a conveying guide wheel group for conveying a long strip aluminum plate 3. The conveying guide wheel group is evenly distributed in multiple groups along the surface of the support base 1. The bending device further includes a first positioning wheel 4, a second positioning wheel 7, a first bending wheel group 8 and a second bending wheel group 9. The first positioning wheel 4 and the second positioning wheel 7 are sequentially distributed in the distribution direction of the conveying guide wheel group. When the long strip aluminum plate 3 passes through the distributed conveying guide wheel group, one side of it is attached to the first positioning wheel 4 and the second positioning wheel 7. The bottoms of the first positioning wheel 4 and the second positioning wheel 7 are both rotatably connected to a first support column 19, and the first support column 19 is fixedly connected to the support base 1, that is, the first support column 19 will not rotate relative to the support base 1, while the first positioning wheel 4 and the second positioning wheel 7 can respectively rotate relative to the corresponding first support column 19, which is convenient for guiding the long strip aluminum plate 3 to pass through; it should be noted that the distance between the first positioning wheel 4 and the second positioning wheel 7 is the length of the first side of the aluminum frame to be bent and formed; a rotary drive mechanism for applying a bending force to the long strip aluminum plate 3 is provided on the second positioning wheel 7;

[0032] The bending wheel set 8 is cooperatively connected to the driving end of the rotary driving mechanism, the bending wheel set 9 is cooperatively connected to the bending wheel set 8, and the rotary driving mechanism, the bending wheel set 8 and the bending wheel set 9 are all provided with push plates 17 for extruding the long strip aluminum plate 3. The rotary driving mechanism drives the corresponding push plate 17 and the bending wheel set 8 to deflect counterclockwise by 90 degrees. During the deflection of the bending wheel set 8, the bending wheel set 9 and the push plate 17 corresponding to the bending wheel set 8 deflect counterclockwise by 90 degrees relative to the bending wheel set 8. During the deflection of the bending wheel set 9, the push plate 17 corresponding to the bending wheel set 9 deflects counterclockwise by 90 degrees relative to the bending wheel set 9. In this way, the long strip aluminum plate 3 can be bent at three positions synchronously, and the rectangular aluminum frame can be quickly obtained, saving the bending processing time and improving the efficiency.

[0033] In some specific implementation schemes, such as Figure 2 shown, the rotary driving mechanism includes a first driven gear 15 and a first driving gear 14. The first driven gear 15 is rotatably sleeved on the corresponding first support column 19 of the positioning wheel two 7. The first driven gear 15 can rotate relative to the first support column 19, that is, the first support column 19 penetrates through the center position of the first driven gear 15, and then limiting rings distributed on the upper and lower sides of the first driven gear 15 are fixedly arranged on the first support column 19 to ensure that the first driven gear 15 is limited to rotate at the corresponding position and will not have a longitudinal position offset. The first driving gear 14 is rotatably connected to the support base 1 through a rotating shaft. A first servo motor 13 for driving the first driving gear 14 is fixedly installed on the support base 1. The first driving gear 14 and the first driven gear 15 are meshed. The push plate 17 corresponding to the rotary driving mechanism is fixedly connected to the upper surface layer of the first driven gear 15 through a bracket, and the initial position of the push plate 17 is attached to one side of the long strip aluminum plate 3 passing through, while the positioning wheel one 4 and the positioning wheel two 7 are distributed on the other side of the long strip aluminum plate 3, and the bending wheel set 8 is cooperatively connected to the first driven gear 15.

[0034] In some specific implementation schemes, combined with Figure 3 and Figure 4 shown, the bending wheel set 8 includes a limiting guide wheel 18, a second support column 20, a second driven gear 21 and a rolling transmission mechanism. The initial position of the limiting guide wheel 18 is flush with the positioning wheel two 7 and the positioning wheel one 4. The second support column 20 is fixedly connected to the bottom of the limiting guide wheel 18. The second support column 20 is fixedly connected to the first driven gear 15 through a cross plate. The second driven gear 21 is rotatably arranged on the second support column 20, and its installation method adopts the connection method between the first driven gear 15 and the first support column 19. The push plate 17 corresponding to the bending wheel set 8 is fixedly connected to the corresponding second driven gear 21 through a bracket. When the first driven gear 15 drives the bending wheel set 8 to deflect, the rolling transmission mechanism rolls along the surface of the support base 1 and drives the second driven gear 21 to rotate.

[0035] Among them, the rolling transmission mechanism includes a wheel frame 22, a roller 27, a steering gear set, and a second driving gear 29. The wheel frame 22 is connected to the second support column 20. A side frame 28 is fixedly connected to one side of the wheel frame 22. The roller 27 is rotatably connected to the side frame 28 through a rotating shaft. The second driving gear 29 meshes with one side of the second driven gear 21, and the second driving gear 29 is rotatably connected to the wheel frame 22 through a rotating shaft. The steering gear set is cooperatively connected between the roller 27 and the second driving gear 29. The roller 27 corresponding to the first bending wheel set 8 contacts the surface of the support seat 1.

[0036] When the first driven gear 15 rotates around the first support column 19, it drives the corresponding push plate 17 to rotate counterclockwise around the second positioning wheel 7 by a certain angle, causing the first bending point to be generated on the long strip aluminum plate 3. And it also drives the entire first bending wheel set 8 to deflect counterclockwise synchronously. During the deflection process of the first bending wheel set 8, the roller 27 corresponding to the first bending wheel set 8 rolls along the surface of the support seat 1. During the rolling process, it drives the second driving gear 29 to rotate through the steering gear set, and the second driving gear 29 drives the second driven gear 21 to rotate. It should be noted that the second driven gear 21 is larger than the second driving gear 29, and the two are in a certain wheel diameter ratio to ensure that after the roller 27 rolls along a quarter-circular path relative to the point where the second positioning wheel 7 is located, the second driven gear 21 rotates 90 degrees, thereby driving the second bending wheel set 9 to deflect synchronously. At the same time, the second driven gear 21 drives the corresponding push plate 17 to deflect around the corresponding limiting guide wheel 18 to squeeze the long strip aluminum plate 3, causing the second bending point to be generated on the long strip aluminum plate 3.

[0037] Among them, the steering gear set includes a first steering bevel gear 25 and a second steering bevel gear 26. The first steering bevel gear 25 is fixedly connected to the second driving gear 29 coaxially, and the two rotate synchronously. The second steering bevel gear 26 is fixedly connected to the roller 27 coaxially, and the second steering bevel gear 26 meshes with the first steering bevel gear 25. During the rolling process of the roller 27, it drives the second steering bevel gear 26 to rotate, and the second steering bevel gear 26 drives the first steering bevel gear 25 to rotate, so that the second driving gear 29 rotates.

[0038] In some specific embodiments, the structure of the second bending wheel set 9 is the same as that of the first bending wheel set 8, and it also includes a limiting guide wheel 18, a second support column 20, a second driven gear 21, and a rolling transmission mechanism. The rolling transmission mechanism also includes a wheel frame 22, a roller 27, a steering gear set, and a second driving gear 29. The second support column 20 corresponding to the second bending wheel set 9 is fixedly connected to the second driven gear 21 corresponding to the first bending wheel set 8 through a cross plate. One side of the second support column 20 corresponding to the first bending wheel set 8 close to the second bending wheel set 9 is fixedly connected with an arc guide plate 30 through a rod. The arc guide plate 30 is a quarter circle arc, and its corresponding center coincides with the central axis of the limiting guide wheel 18 corresponding to the first bending wheel set 8. The roller 27 corresponding to the second bending wheel set 9 contacts the arc guide plate 30, and the rolling track of the arc guide plate 30 coincides with that of the roller 27 corresponding to the second bending wheel set 9.

[0039] When the second driven gear 21 corresponding to the first bending wheel set 8 deflects, it drives the entire second bending wheel set 9 to deflect. The second support column 20 corresponding to the first bending wheel set 8 rotates around the second positioning wheel 7, and the arc guide plate 30 moves together with the second support column 20 of the first bending wheel set 8. At this time, the second bending wheel set 9 deflects relative to the first bending wheel set 8 and also relative to the arc guide plate 30. Then the roller 27 corresponding to the second bending wheel set 9 rolls along the arc guide plate 30, which can avoid the influence on the deflection of the corresponding second driven gear 21 when the second bending wheel set 9 deflects as a whole relative to the first bending wheel set 8. In this way, the second driven gear 21 corresponding to the second bending wheel set 9 deflects relative to the second support column 20 corresponding to the second bending wheel set 9. In this way, the second driven gear 21 corresponding to the second bending wheel set 9 drives the corresponding push plate 17 to deflect relative to the corresponding limiting guide wheel 18 and extrude the long strip aluminum plate 3, so that the long strip aluminum plate 3 generates a third bending point. Since they all deflect in the same direction, the long strip aluminum plate 3 is bent into a square shape with a hole in the middle. The first positioning wheel 4, the second positioning wheel 7, the first bending wheel set 8, and the second bending wheel set 9 are respectively distributed at the four corner positions of the aluminum frame for positioning. The bending points at different positions are obtained by synchronous bending without bending one by one, improving the bending processing efficiency.

[0040] In some specific embodiments, to facilitate improving the flexibility of the entire device. A strip-shaped sliding groove 23 is formed on the second support column 20. One end of the wheel frame 22 is slidably connected in the strip-shaped sliding groove 23. An adjusting screw 24 is rotatably connected in the strip-shaped sliding groove 23. The adjusting screw 24 passes through the wheel frame 22 and is slidably connected to the end of the strip-shaped sliding groove 23, and the adjusting screw 24 is threadedly connected to the wheel frame 22.

[0041] When it is only necessary to bend the long strip aluminum plate 3 once to obtain an L-shaped structure, the adjusting screw 24 on the second support column 20 corresponding to the first bending wheel set 8 can be rotated, so that the wheel frame 22 slides up along the strip-shaped chute 23. In this way, the roller 27 also rises accordingly, thus disengaging from the support surface. In this way, during the deflection process of the entire first bending wheel set 8 driven by the first driven gear 15, the corresponding roller 27 cannot roll, so the corresponding second driven gear 21 cannot be deflected, and subsequent bending cannot be carried out.

[0042] In some specific implementation schemes, in order to facilitate cutting the aluminum frame bent into a square shape from the entire long strip aluminum plate 3, as shown in combination with Figure 2 and Figure 5 , a first electric telescopic rod 10 is fixedly installed on the push plate 17 corresponding to the second bending wheel set 9. A cutting machine 11 is fixedly installed at the telescopic end of the first electric telescopic rod 10. After the square aluminum frame is bent and formed, the cutting machines 11 distributed on the push plate 17 of the second bending wheel set 9 are exactly facing the part of the long strip aluminum plate 3 close to the first positioning wheel 4. At this time, control the first electric telescopic rod 10 to extend and start the cutting machine 11, so that the cutting machine 11 cuts off the part between the long strip aluminum plate 3 and the aluminum frame, which is convenient for removing the formed aluminum frame and convenient for subsequent processing.

[0043] In some specific implementation schemes, a second electric telescopic rod 6 is fixedly connected to the support base 1. The telescopic end of the second electric telescopic rod 6 is fixedly connected to a positioning pressure plate 5, and the positioning pressure plate 5 is aligned on one side of the first positioning wheel 4, and one end of the positioning pressure plate 5 extends close to the second positioning wheel 7. During bending, the positioning pressure plate 5 presses the part of the long strip aluminum plate 3 between the first positioning wheel 4 and the second positioning wheel 7, avoiding the arching phenomenon of the part of the long strip aluminum plate 3 at the current position during the bending process. And when the end of the positioning pressure plate 5 covers the cutting position, a notch 16 for the cutter head of the cutting machine 11 to pass through can also be opened on the positioning pressure plate 5 to prevent damage caused by the interaction between the positioning pressure plate 5 and the cutting machine 11.

[0044] In some specific implementation schemes, each set of conveying guide wheel sets includes two rotating wheels 2, and the two rotating wheels 2 are symmetrically distributed on both sides of the long strip aluminum plate 3. The rotating wheels 2 are rotatably connected to the support base 1 through a rotating shaft to clamp the long strip aluminum plate 3. A second servo motor 12 is fixedly installed on the support base 1, and the second servo motor 12 is used to drive one of the rotating wheels 2 to rotate, so as to facilitate the clamping and conveying of the long strip aluminum plate 3; the limiting guide wheels 18 corresponding to the first bending wheel set 8, the limiting guide wheels 18 corresponding to the second bending wheel set 9 and each rotating wheel 2 have the same structure, and both include a wheel body and a convex ring distributed at the bottom of the wheel body. When the long strip aluminum plate 3 contacts the surface of the rotating wheel 2 or the limiting guide wheel 18, the bottom of the long strip aluminum plate 3 is supported by the convex ring, and at the same time, after the aluminum frame is bent and formed later, it can be directly taken away from above.

[0045] For the convenience of those skilled in the art to understand the embodiments of this solution, the working principle of this solution will be briefly described below in combination with a specific application scenario:

[0046] First, pass the long aluminum plate 3 through multiple groups of conveying wheels distributed in pairs, and successively pass through the first positioning wheel 4, the second positioning wheel 7, the first bending wheel group 8, and the second bending wheel group 9, and make the long aluminum plate 3 exceed the position of the second bending wheel group 9 by a certain length, so that the conveying position of the long aluminum plate 3 is in place in one step. At this time, each push plate 17 is attached to one side of the long aluminum plate 3.

[0047] Then control the first servo motor 13 to drive the first driving gear 14, so that the first driving gear 14 drives the first driven gear 15 to rotate counterclockwise by 90 degrees. At this time, the first driven gear 15 rotates around the first support column 19, and it drives the corresponding push plate 17 to rotate counterclockwise by 90 degrees around the second positioning wheel 7. The current push plate 17 squeezes the bent long aluminum plate 3, causing the long aluminum plate 3 to generate a first bending point, and it also drives the entire first bending wheel group 8 to deflect counterclockwise synchronously;

[0048] During the deflection of the first bending wheel group 8 relative to the second positioning wheel 7, the corresponding roller 27 of the first bending wheel group 8 rolls along the surface of the support base 1. During the rolling process, it drives the second driving gear 29 to rotate through the steering gear set. The second driving gear 29 drives the second driven gear 21 to rotate. The second driven gear 21 rotates counterclockwise by 90 degrees, and drives the second bending wheel group 9 to deflect synchronously. At the same time, the second driven gear 21 drives the corresponding push plate 17 to deflect around the corresponding limit guide wheel 18 to squeeze the long aluminum plate 3, causing the long aluminum plate 3 to generate a second bending point;

[0049] When the first bending wheel group 8 deflects relative to the second positioning wheel 7, the set arc guide plate 30 moves together with the second support column 20 of the first bending wheel group 8. At this time, the second bending wheel group 9 deflects relative to the first bending wheel group 8 and also deflects relative to the arc guide plate 30. Then the corresponding roller 27 of the second bending wheel group 9 rolls along the arc guide plate 30. In this way, the second driven gear 21 corresponding to the second bending wheel group 9 deflects relative to the second support column 20 corresponding to the second bending wheel group 9. In this way, the second driven gear 21 corresponding to the second bending wheel group 9 drives the corresponding push plate 17 to deflect relative to the corresponding limit guide wheel 18 to squeeze the long aluminum plate 3, causing the long aluminum plate 3 to generate a third bending point. Since they all deflect in the same direction, the long aluminum plate 3 is bent into a square shape. The first positioning wheel 4, the second positioning wheel 7, the first bending wheel group 8, and the second bending wheel group 9 are respectively distributed at the four corner positions of the aluminum frame to achieve positioning. The bending points at different positions are bent synchronously, and there is no need to bend them one by one, improving the bending processing efficiency.

[0050] After the rectangular aluminum frame is bent and formed, the cutting machines 11 distributed on the push plate 17 of the second bending wheel set 9 are exactly opposite to the part of the long strip aluminum plate 3 close to the first positioning wheel 4. At this time, control the first electric telescopic rod 10 to extend and start the cutting machines 11, so that the cutting machines 11 cut off the part between the long strip aluminum plate 3 and the aluminum frame, which is convenient for removing the formed aluminum frame and facilitating subsequent processing.

[0051] When it is only necessary to bend the long strip aluminum plate 3 once to obtain an L-shaped structure, the adjusting screw 24 on the second support column 20 corresponding to the first bending wheel set 8 can be rotated, so that the wheel frame 22 slides up along the strip-shaped chute 23. In this way, the roller 27 also rises accordingly, thus disengaging from the support surface. In this way, during the deflection process of the entire first bending wheel set 8 driven by the first driven gear 15, the corresponding roller 27 cannot roll, so that the corresponding second driven gear 21 cannot be deflected, and thus subsequent bending cannot be performed.

[0052] The above has described several embodiments of the present invention in detail, but the embodiments of the present invention are not limited thereto and cannot be considered as used to limit the scope of implementation of the present invention.
