[0033] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0034] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0035] Example 1: Reference Figure 1-Figure 12A rock wool color steel plate lap edge bending device includes a frame 1, an upper mold 2 and a lower mold plate 3 are arranged on the frame 1, a mold groove 4 corresponding to the upper mold 2 is opened on the lower mold plate 3, a movable plate 5 is slidably arranged on the frame 1, and also includes a slide rod 6 fixedly connected to the movable plate 5, a rotating rod 7 is rotatably connected to the frame 1, and a spiral slide groove 8 corresponding to the slide rod 6 is opened on the rotating rod 7, clamping members 10 are arranged on both sides of the frame 1, a synchronous belt 9 is transmission-connected between the two groups of clamping members 10, and a linked driving member 11 is arranged between the rotating rod 7 and the clamping member 10.

[0036] In the present invention, when the overlapping edge of the rock wool color steel plate is bent, the rock wool color steel plate is transported to the top of the mold groove 4 of the lower mold plate 3 on the frame 1, and the sliding rod 6 is driven downward by the movable plate 5 to slide and cooperate with the spiral sliding groove 8 on the rotating rod 7, so that the rotating rod 7 rotates. While the rotating rod 7 rotates, the driving member 11 and the clamping member 10 are linked to each other, so that the clamping member 10 clamps and fixes the rock wool color steel plate on the frame 1, and then the bending operation is performed, which can realize automatic fixation of the rock wool color steel plate before bending. Compared with the traditional method of manually controlling the cylinder, bolts and other tools to fix the rock wool color steel plate by the staff, it has a faster fixing speed, is convenient for continuous production, and improves the efficiency of bending the overlapping edge of the rock wool color steel plate.

[0037] Example 2: Reference Figure 1-Figure 10 , which is basically the same as the first embodiment, and further, a support frame 12 is fixedly installed on the top of the frame 1, a hydraulic cylinder 13 is fixedly installed on the support frame 12, an output end of the hydraulic cylinder 13 is fixedly connected to the movable plate 5, the upper mold 2 is fixedly installed on the bottom of the movable plate 5, and the lower mold plate 3 is fixedly installed on the inner walls on both sides of the frame 1.

[0038] In the present invention, by starting the hydraulic cylinder 13 to drive the movable plate 5 downward, the upper mold 2 is driven downward and at the same time the slide rod 6 is driven to cooperate with the spiral slide groove 8 on the rotating rod 7. The upper mold 2 contacts the rock wool color steel plate and enters the mold groove 4 on the lower mold plate 3 to bend the edge of the rock wool color steel plate.

[0039] A conveyor belt device 14 is fixedly installed on the left and right sides of the frame 1 respectively, a mounting ear 15 is fixedly connected to one side of the movable plate 5, a guide rod 16 is fixedly connected to one side of the frame 1, and the mounting ear 15 is slidably connected to the guide rod 16.

[0040] In the present invention, the conveyor belt device 14 is a prior art. The conveyor belt device 14 can automatically control the transportation of the rock wool color steel plate. When the movable plate 5 moves downward, it slides on the guide rod 16 through the mounting ear 15, which can guide the sliding of the movable plate 5 and the upper mold 2, making the bending process of the rock wool color steel plate more stable.

[0041] The clamping member 10 includes screw rods 1001 rotatably connected to both sides of the frame 1 , two groups of toothed clamping plates 1002 are threadedly connected to the two groups of screw rods 1001 , and guide rods 1003 are fixedly connected to both sides of the frame 1 .

[0042] In the present invention, by rotating the screw 1001, the two screws 1001 can be rotated simultaneously through the synchronous belt 9, and under the guidance of the guide rod 1003 on the toothed splint 1002, the two groups of toothed splints 1002 are controlled to press down and fix the rock wool color steel plate. It should be noted that the toothed splint 1002 is a kind of with a serrated pattern. When clamping some relatively smooth rock wool color steel plates, it can better embed into the surface of the plate and increase friction.

[0043] The driving member 11 includes a driving gear 1101 fixedly connected to the bottom of the rotating rod 7, and a limiting support ring 1102 is fixedly connected to the bottom of the frame 1 close to the rotating rod 7. The bottom of the limiting support ring 1102 is rotatably connected to a first driven gear 1103 that meshes with the driving gear 1101.

[0044] In the present invention, when the movable plate 5 moves downward, the driving gear 1101 is rotated clockwise downward by the sliding rod 6. When the rotating rod 7 rotates, the driving gear 1101 is driven to rotate and engage with the first driven gear 1103, so that the first driven gear 1103 rotates counterclockwise. The first driven gear 1103 can be supported by the limiting support ring 1102.

[0045] A circular groove is provided at the bottom of the first driven gear 1103, and a plurality of first strip plates 1104 are fixedly connected around the inner wall of the circular groove of the first driven gear 1103, a plurality of second strip plates 1105 are hingedly connected around the screw rod 1001 close to the first driven gear 1103, a torsion spring 1106 is fixedly connected between the second strip plates 1105 and the screw rod 1001, and a plurality of baffle plates 1107 are fixedly connected to the screw rod 1001 close to the first driven gear 1103, and one side of the baffle plate 1107 is against the second strip plate 1105.

[0046] In the present invention, when the first driven gear 1103 rotates counterclockwise, it will drive the first strip plate 1104 on its inner wall to rotate at the same time, and conflict with the second strip plate 1105 on the screw 1001. Under the action of the torsion spring 1106, the second strip plate 1105 makes the screw 1001 rotate along with the first driven gear 1103, and then through the synchronous belt 9, the two sets of toothed clamps 1002 slide downward at the same time to press down and clamp the rock wool color steel plate. When the two sets of toothed clamps 1002 slide to the bottom to press and fix the rock wool color steel plate, the upper mold 2 has not entered the mold groove 4 at this time, and the rotating rod 7 is still rotating. At this time, the first strip plate 1104 continues to conflict with the second strip plate 1105. Since the rock wool color steel plate has been fixed, the screw 1001 cannot continue to rotate. At this time, the first strip plate 1104 continues to clamp the second The strip plate 1105 is in conflict, and the second strip plate 1105 will be squeezed to one side of the torsion spring 1106 at this time. Then the first driven gear 1103 drives the first strip plate 1104 to slide across the second strip plate 1105, and automatically disengages from the second strip plate 1105 on the screw 1001, which can automatically stop applying pressure to the rock wool color steel plate, thereby being able to press down and fix the rock wool color steel plate while protecting the rock wool color steel plate from deformation caused by excessive downward pressure; after the bending is completed, the movable plate 5 moves up under the action of the hydraulic cylinder 13, causing the rotating rod 7 to rotate in the opposite direction, controlling the first driven gear 1103 to rotate in the opposite direction, driving the first strip plate 1104 to rotate in the opposite direction, and under the action of the baffle 1107, the second strip plate 1105 can be driven to rotate in the opposite direction, controlling the screw 1001 to reverse, and causing the toothed clamping plate 1002 to slide up and reset.

[0047] Example 3: Reference Figure 1-Figure 12 , which is basically the same as the first embodiment, and further, a plurality of through holes 401 are provided on the bottom wall of the mold groove 4 of the lower mold plate 3, and a bearing rod 17 is fixedly connected to the bottom of the frame 1 near the driving gear 1101, and a second driven gear 18 meshing with the driving gear 1101 is rotatably connected to the bottom of the bearing rod 17, and a ratchet groove 19 is provided at the bottom of the second driven gear 18, and a ratchet wheel 20 corresponding to the ratchet groove 19 is arranged in the ratchet groove 19.

[0048] In the present invention, while the rotating rod 7 drives the driving gear 1101 to rotate, it also engages with the second driven gear 18 to make it rotate. When the movable plate 5 moves downward, the ratchet groove 19 inside the second driven gear 18 will not cause the ratchet 20 to rotate. The ratchet 20 will only rotate when the movable plate 5 is reset upward.

[0049] A connecting rod 21 is fixedly connected to the bottom of the ratchet 20, a bearing seat 22 is fixedly connected to the conveyor belt device 14, the connecting rod 21 is rotatably connected to the bearing seat 22, a cam 23 is fixedly connected to the connecting rod 21, a T-shaped plate 24 is fixedly connected to the bottom of the frame 1 near the cam 23, a round rod 25 corresponding to the cam 23 is slidably connected to the T-shaped plate 24, a first spring 26 is sleeved on the round rod 25, and both ends of the first spring 26 are fixedly connected to the round rod 25 and the T-shaped plate 24 respectively.

[0050] In the present invention, when the movable plate 5 is reset upward, the ratchet 20 rotates to drive the connecting rod 21 to rotate, and then drives the cam 23 to rotate. When the protruding portion of the cam 23 conflicts with the round rod 25, the round rod 25 compresses the first spring 26 to slide under the action of the T-shaped plate 24. When the protruding portion of the cam 23 does not conflict with the round rod 25, the round rod 25 will automatically reset under the action of the first spring 26.

[0051] A push rod 27 is slidably connected to the T-shaped plate 24, and a trapezoidal block 28 corresponding to the round rod 25 is fixedly connected to the bottom of the push rod 27. Vertical rods 29 are fixedly connected to both sides of the bottom of the lower mold plate 3, and a connecting plate 30 is fixedly connected to the top of the push rod 27. Rubber hammers 31 are fixedly connected to both sides of the connecting plate 30. The rubber hammer 31 and the connecting plate 30 are both slidably connected to the vertical rod 29. A second spring 32 is sleeved on the push rod 27, and both ends of the second spring 32 are respectively against the trapezoidal block 28 and the T-shaped plate 24.

[0052] In the present invention, when the round rod 25 compresses the first spring 26 to slide, it will contact the trapezoidal block 28 and slide along the inclined surface of the trapezoidal block 28. Under the action of the push rod 27, when the trapezoidal block 28 is contacted by the round rod 25, it will drive the push rod 27 to compress the second spring 32 to slide upward, thereby driving the connecting plate 30 and the rubber hammer 31 to slide upward on the vertical rod 29, so that the two groups of rubber hammers 31 knock the lower mold plate 3 and the through hole 401 inside the mold groove 4 as a whole once, and knock back and forth in this way. After the bending of the rock wool color steel plate is completed, when the movable plate 5 is reset upward, the lower mold plate 3 is reciprocated to produce slight vibration, thereby making the coating debris generated by the rock wool color steel plate during bending fall from the through hole 401 at the bottom of the mold groove 4, thereby realizing the automatic cleaning of the coating debris generated after the rock wool color steel plate is bent, which will not affect the next bending. Compared with the traditional manual hand-held air blow gun cleaning, it has the effect of automatic cleaning without manual operation.

[0053] Embodiment 4: A method for bending the overlapped edge of a rock wool color steel plate, which is performed by the following steps:

[0054] S1. When the rock wool color steel plate is subjected to the overlapping edge bending operation, the rock wool color steel plate is transported to the top of the lower mold plate 3 by the conveyor belt device 14, and then the hydraulic cylinder 13 is started to move the movable plate 5 and the upper mold 2 downward at the same time, and the upper mold 2 squeezes the rock wool color steel plate into the mold groove 4 on the lower mold plate 3, and the bending of the rock wool color steel plate is completed;

[0055] S2. When the movable plate 5 moves downward, the sliding rod 6 is driven to slide on the spiral slide groove 8 on the rotating rod 7, so that the rotating rod 7 rotates, and the driving member 11 is linked with the clamping member 10 to achieve that the rock wool color steel plate is fixed on the frame 1 and the conveyor belt device 14 in advance when the rock wool color steel plate is not bent, so as to achieve rapid fixation and ensure that the bending position of the rock wool color steel plate is accurate when it is bent.
