DETAILED DESCRIPTION

[0032] In order to make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0033] The present invention provides a metal bending device for keel processing, such as Figures 1 to 8 As shown, it includes a keel body 1 and a glass window keel 35. The outer wall of one side of the keel body 1 is rotatably connected to two symmetrical support rollers 2. The outer wall of one side of the keel body 1 is fixedly installed with two symmetrical first electric telescopic rods 3. The output end of the first electric telescopic rod 3 is fixedly installed with a splint 4. The inner wall of the keel body 1 is fixedly installed with a support frame 5. The outer wall of one side of the support frame 5 is fixedly installed with two symmetrical second electric telescopic rods 6. The output end of the second electric telescopic rod 6 is fixedly installed with a moving frame 7. The outer wall of one side of the moving frame 7 is rotatable. A circular saw 8 is dynamically connected, a first servo motor 9 is fixedly installed on the outer wall of the movable frame 7 away from the circular saw 8, and the first servo motor 9 is connected to the circular saw 8 through a belt and a pulley. A second servo motor 10 is fixedly installed in the middle of the outer wall of the support frame 5, and a rotating frame 11 is fixedly installed on the output end of the second servo motor 10. The inner wall of the rotating frame 11 away from the second servo motor 10 is rotatably connected to a rotating rod 12. An arc groove 13 is opened on the outer wall of one side of the dragon bone bending machine body 1, and the outer wall of the rotating rod 12 is slidably connected to the inner wall of the arc groove 13;

[0034] The working principle of the above components is as follows: when processing the keel of the glass window, the aluminum alloy tube is transported to the middle of the support roller 2 through an additional transmission mechanism, so as to position the aluminum alloy tube, and then the aluminum alloy tube is continuously transported to the clamping plate 4, so that one end of the aluminum alloy tube moves to the rotating frame 11, and then the clamping plate 4 is pushed by the first electric telescopic rod 3 to clamp the aluminum alloy tube, and then the second servo motor 10 is started, and the rotating frame 11 is driven to rotate in the arc groove 13 by the second servo motor 10, so that the rotating rod 12 will push the aluminum alloy tube upward to bend ninety degrees, and then the aluminum alloy tube is released, and the aluminum alloy tube is continuously driven to move to the rotating frame 11, and then the aluminum alloy tube is bent by the above components, and finally the aluminum alloy tube is bent into a rectangular shape, and then the second electric telescopic rod 6 is started, and the circular saw 8 is pushed to move toward the aluminum alloy tube by the second electric telescopic rod 6, and at the same time, the second servo motor 10 is started to drive the circular saw to rotate to cut off the bent aluminum alloy tube, so that the prototype of the glass window keel is processed.

[0035] The inner wall of the rotating rod 12 is provided with a pushing device, which includes: a moving rod 14 and an arc-shaped top block 21, and the pushing device is used to push the glass window keel 35 to move;

[0036] The outer wall of the arc plate 16 is fixedly connected to the inner wall of the main body 1 of the dragon bone bending machine, and an arc frame 17 is fixedly installed on the outer wall of one side of the arc plate 16. A plurality of racks 18 are fixedly installed on the side of the arc frame 17 facing the moving rod 14. A gear 15 is fixedly installed on the outer wall of one end of the rotating rod 12 close to the arc plate 16, and the gear 15 is meshed with the rack 18. The outer wall of one side of the arc top block 21 is fixedly connected to the outer wall of the top of the arc plate 16. The outer wall of one end of the moving rod 14 close to the arc plate 16 is rotatably connected to a universal wheel 20. A first spring 19 is sleeved between the moving rod 14 and the gear 15. The outer wall of one end of the first spring 19 is fixedly connected to the outer wall of the moving rod 14, and the outer wall of the universal wheel 20 is rollingly connected to the outer wall of one side of the arc plate 16.

[0037] The working principle of the above components is as follows: in order to enable the keel to quickly detach from the bending equipment, the second servo motor 10 can be used to drive the rotating frame 11 to rotate upward. Here, it is necessary to continuously drive the rotating frame 11 to rotate so that the rotating frame 11 rotates to the top of the arc groove 13, so that the gear 15 will rotate on the rack 18, thereby driving the rotating rod 12 to rotate. When the rotating rod 12 rotates, it will push the keel to move in the direction of the first electric telescopic rod 3. After the second servo motor 10 drives the rotating frame 11 to rotate upward for a period of time, the universal The wheel 20 will roll onto the arc-shaped top block 21. Since the thickness of the area where the arc-shaped top block 21 is installed on the arc plate 16 is thicker than other areas, the moving rod 14 will be squeezed to move. Here, when the universal wheel 20 rotates to the arc-shaped top block 21, the moving rod 14 will face the glass window keel. Therefore, when the moving rod 14 is extended, the keel will be pushed out of the keel fracture bending machine body 1. In this way, the rotating rod 12 and the moving rod 14 can not only process the keel but also cut the processed keel, thus saving the cost of installing an additional cutting device and improving the processing efficiency of the glass window keel.

[0038] Metal blocks 22 are fixedly mounted on both sides of the outer wall of the rotating rod 12 close to the rotating frame 11, and two symmetrical rubidium magnets 23 are fixedly mounted on one side of the outer wall of the rotating frame 11 close to the arc plate 16, and the metal blocks 22 are magnetically connected to the rubidium magnets 23;

[0039] The working principle of the above components is as follows: in order to prevent the rotating rod 12 from rotating randomly, the metal block 22 and the rubidium magnet 23 are provided, so that the rotating rod 12 can be rotated only when there is sufficient power.

[0040] The inner walls of both sides of the rotating rod 12 away from the arc-shaped plate 16 are connected with a pressure device, which includes: a third spring 26, a sliding block 27, and a clamping block 28. The pressure device is used to squeeze the spring block 25 and the second spring 24;

[0041] A second spring 24 is fixedly installed on the inner wall of the side of the moving rod 14 away from the arc plate 16, and a spring block 25 is fixedly installed on the outer wall of the side of the second spring 24 away from the moving rod 14. The outer wall of the spring block 25 is slidably connected to the inner wall of one side of the moving rod 14, the outer wall of one side of the third spring 26 is fixedly connected to the inner wall of one side of the rotating rod 12, and the outer wall of the other side of the third spring 26 is fixedly connected to the outer wall of one side of the sliding block 27, the outer wall of the sliding block 27 is slidably connected to the inner wall of one side of the rotating rod 12, and the outer wall of the other side of the sliding block 27 is fixedly connected to the outer wall of one side of the locking block 28, a through hole is opened in the middle position of the sliding block 27, and the bottom outer wall of the through hole is inclined, the outer walls of both sides of the locking block 28 are trapezoidal in shape, and the middle position of the locking block 28 is rectangular in shape, and the outer wall of the side of the spring block 25 away from the arc plate 16 is engaged with the outer wall of the middle position of the locking block 28;

[0042] The working principle of the above-mentioned components is as follows: in order to prevent the keel from being still hung on a certain component at other positions after being pushed by the moving rod 14, when the moving rod 14 moves, the spring block 25 will be blocked by the locking block 28, and the spring block 25 will shrink into the moving rod 14. When the moving rod 14 contacts the locking block 28, because the two sides of the locking block 28 are set to be trapezoidal and inclined toward the moving rod 14, the moving rod 14 will squeeze the locking block 28 when it contacts the locking block 28. When the locking block 28 moves into the rotating rod 12, the spring block 25 will pop out quickly, thereby quickly pushing the keel, so that the keel has enough power to leave the bending equipment as a whole.

[0043] The inner wall at the middle position of the rotating rod 12 is rotatably connected with a connecting rod 29, and a rotating page 30 is fixedly installed on the outer wall of the connecting rod 29 on the side away from the arc plate 16. The inner walls on both sides of the rotating rod 12 away from the arc plate 16 are rotatably connected to the limiting blocks 31, and the outer wall on one side of the limiting blocks 31 is rotatably connected to the outer wall on one side of the rotating page 30. The inner walls on both sides of the rotating rod 12 away from the arc plate 16 are slidably connected with push rods 32, and the outer walls on both sides of the push rod 32 are fixedly installed with fourth springs 33, and the outer wall on the other side of the fourth spring 33 is fixedly connected to the inner wall on one side of the rotating rod 12, and the outer wall of one end of the push rod 32 contacts the outer wall on one side of the limiting block 31, and the outer wall of the other end of the push rod 32 contacts the outer wall at the middle position of the sliding block 27;

[0044] The working principle of the above components is as follows: when the keel is closed, the keel needs to be fixed. At this time, the second servo motor 10 drives the rotating rod 12 to rotate and change its position. At the same time, the rotating rod 12 itself will also rotate and change its direction, so that the moving rod 14 faces the keel. At this time, the rotating limit block 31 is rotated so that the notch of the limit block 31 faces the rotating page 30. At this time, the rotating page 30 can be rotated in the direction of the rotating rod 12. While rotating the limit block 31, the push rod 32 will be squeezed. At this time, the push rod 32 will enter the opening of the sliding block 27. Because the bottom of the opening of the sliding block 27 is provided with a slope inclined toward the push rod 32, when the push rod 32 squeezes the sliding block 27, the sliding block 27 will squeeze the third spring 26, so that the clamping block 28 can move into the rotating rod 12, so that the clamping block 28 will not block the movement of the spring block 25. Therefore, when the spring block 25 moves toward the keel, it will push the keel toward the rotating page 30, thereby clamping the keel, so that one side of the keel can be fixed, and together with the first electric telescopic rod 3 and the clamping block, the two sides of the keel can be fixed, thereby preventing the keel from shaking during the closing process.

[0045] Working principle: When processing the keel of the glass window, the aluminum alloy tube is transported to the rotating frame 11, and then the clamping plate 4 is pushed by the first electric telescopic rod 3 to clamp the aluminum alloy tube, and then the second servo motor 10 is started to drive the rotating frame 11 to rotate in the arc groove 13, so that the rotating rod 12 pushes the aluminum alloy tube to bend ninety degrees, and then the aluminum alloy tube is released, and the aluminum alloy tube is continuously driven to move to the rotating frame 11, and then the above work is repeated, and finally the aluminum alloy tube is bent into a rectangular shape, and then the second electric telescopic rod 6 is started to push the circular saw 8 to move toward the aluminum alloy tube. The bent aluminum alloy tube is cut off, and then the second servo motor 10 continuously drives the rotating frame 11 to rotate, so that the rotating frame 11 rotates to the top of the arc groove 13, so that the rotating rod 12 rotates and changes direction, and at the same time the universal wheel 20 rolls onto the arc top block 21, so that the moving rod 14 moves toward the glass window keel, and when the moving rod 14 moves, the spring block 25 will be blocked by the locking block 28, and when the moving rod 14 contacts the locking block 28, it will squeeze the locking block 28, and then the spring block 25 will pop out quickly, and quickly push the keel away from the bending equipment.

[0046] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them.
