DETAILED DESCRIPTION

[0033] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments, but is not intended to limit the present invention.

[0034] A bending device for aluminum profile processing, such as Figure 1-Figure 6 As shown, it includes a processing table 1, a support plate 13, a bending mechanism and an adjusting mechanism. A processing plane 11 and a processing plane 2 12 are arranged on the top of the processing table 1. The height of the processing plane 11 is lower than that of the processing plane 2 12. The top of the processing plane 2 12 is connected to the support plate 13. The support plate 13 is provided with a bending mechanism for bending the profile 100, and the bending mechanism is provided with an adjusting mechanism.

[0035] like Figure 5 and Figure 6 As shown, the bending mechanism includes a guide rail 3, a sliding block 31, a fixing bolt 32, a mounting frame 33, a cylinder 1 34, a limiting wheel 35 and an extrusion block 36. The guide rail 3 is installed on the front side of the support plate 13. Two sliding blocks 31 are slidably connected to the guide rail 3. The sliding blocks 31 are threadedly connected with fixing bolts 32. The fixing bolts 32 can rotate to resist the guide rail 3 through the threads, thereby fixing the sliding blocks 31. The front side of the sliding block 31 is connected to the mounting frame 33. The limiting wheel 35 is rotatably connected to the mounting frame 33. A cylinder 1 34 is installed on the top of the mounting frame 33. The telescopic rod of the cylinder 1 34 is connected with an extrusion block 36 for bending the profile 100, and the extrusion block 36 is fan-shaped.

[0036] like Figure 6As shown, the adjustment mechanism includes an adjustable limit block 41 and a fixed screw 42. The adjustable limit block 41 is slidably connected to the bottom of the extrusion block 36. The adjustable limit block 41 is fan-shaped and has the same size as the extrusion block 36. The extrusion block 36 is threadedly connected to the fixed screw 42. The fixed screw 42 can rotate to resist the extrusion block 36, thereby fixing the extrusion block 36.

[0037] When the profile 100 needs to be bent, the bending device can be used. Initially, the telescopic rod of the cylinder 1 34 is in an extended state. When in use, the profile 100 is first placed between the extrusion blocks 36 and the limit wheels 35 on both sides. If the profile is in a vertical shape, the fixed screw 42 is loosened, and then the adjustable limit block 41 is adjusted to be flush with the extrusion block 36, and then the vertical profile can be extruded. If the profile is an L-shaped profile, the fixed screw 42 is loosened, and then the adjustable limit block 41 is pulled to move and adjust until the rear side of the adjustable limit block 41 is aligned with the rear side of the extrusion block 36. The distance between the two sides is equal to the thickness of the protrusion at the bottom of the L-shaped profile 100. Subsequently, when placing the L-shaped profile, the protrusion at the bottom of the L-shaped profile 100 is located at the rear side of the adjustable limit block 41. After placement, when extruding, the telescopic rod of the cylinder 34 is controlled to retract and drive the extrusion block 36 to move backward. When the extrusion block 36 moves, it drives the adjustable limit block 41 to move, thereby extruding the front side of the profile 100, and the two limit wheels 35 can limit the rear side of the profile 100. The cooperation of the extrusion block 36 and the limit wheel 35 extrudes and bends the profile 100 to Figure 2 After the extrusion is completed, the telescopic rod of the cylinder 1 34 is controlled to extend, and then the profile 100 is controlled to rotate 90 degrees. After the rotation is completed, the profile 100 is pushed to move to the left, so that the position relationship between the profile 100, the limiting wheel 35 and the extrusion block 36 is as follows: Figure 3 As shown, at this time, the telescopic rod of the cylinder 34 is retracted to drive the extrusion block 36 and the adjustable limit block 41 to bend the profile 100 again, so that the bending of the profile 100 is completed. Figure 4 As shown in the state, the bending work of the profile 100 is completed, and when the bending work is performed, if an L-shaped profile is encountered, it is only necessary to adjust the position of the adjustable limit block 41, and there is no need to replace the extrusion mold, which is more convenient to operate. In actual operation, if the length and width of the bending need to be adjusted, the fixing bolts 32 can be loosened, and then the two sliding blocks 31 can be pulled to move for adjustment.

[0038] like Figure 7 and Figure 8As shown, a return mechanism is also included, and the return mechanism includes a bracket 51, a sliding plate 52 and an elastic member 53. The bracket 51 is connected to the mounting frame 33, and the sliding plate 52 is slidably connected to the front side of the bracket 51. The front side of the sliding plate 52 abuts against the rear side of the extrusion block 36. Four elastic members 53 are connected between the sliding plate 52 and the bracket 51 at intervals, and the elastic member 53 is a return spring.

[0039] When placing the profile 100, first control the telescopic rod of the cylinder 34 to extend again, and then the profile 100 can be placed between the extrusion block 36 and the sliding plate 52. Subsequently, during extrusion, the profile 100 will push the sliding plate 52 to move backward, and the elastic member 53 will be compressed. After molding, when the cylinder 34 drives the extrusion block 36 to move forward, the sliding plate 52 is reset under the action of the elastic member 53 to push the profile 100 out, thereby achieving the effect of automatically pushing out the profile 100.

[0040] like Fig. 9 and Fig.10 As shown, it also includes a lifting mechanism, which includes a top plate 61, a connecting frame 62 and a second cylinder 63. The top rear side of the processing table 1 is slidably connected with the top plate 61, and the top plate 61 is located at the processing plane 11. The top of the processing table 1 is installed with a second cylinder 63, and the telescopic rod of the second cylinder 63 is connected with a connecting frame 62. The connecting frame 62 is connected to the top plate 61, so that the operation of the second cylinder 63 can drive the top plate 61 to move up and down through the connecting frame 62, thereby lifting the profile 100 through the top plate 61.

[0041] In the initial state, the telescopic rod of cylinder 2 63 is in an extended state. When placing the profile 100, the profile 100 can be placed on the top plate 61. After placement, when the profile 100 needs to be controlled to move upward, the telescopic rod of cylinder 2 63 is controlled to retract and drive the top plate 61 to move upward through the connecting frame 62, thereby lifting the profile 100 to between the extrusion block 36 and the sliding plate 52, and then the cylinder 1 34 is controlled to drive the extrusion block 36 to press against the profile 100. In this way, there is no need to manually hold the profile 100 and wait for the extrusion block 36 to move and the sliding plate 52 to clamp the profile 100, which makes operation more convenient.

[0042] like Fig.11 and Fig.12 As shown, a fixing mechanism is also included, and the fixing mechanism includes an air pump 71, an exhaust pipe 72 and an air suction terminal 73. The air pump 71 is installed on the top of the processing table 1, and the air inlet end of the air pump 71 is connected to the exhaust pipe 72. The exhaust pipe 72 is a hose, and a plurality of air suction terminals 73 are evenly spaced and installed on the exhaust pipe 72. The air suction terminal 73 extends into the top plate 61, so that the air suction terminal 73 can absorb air to adsorb the profile 100 on the top plate 61.

[0043] After the profile 100 is placed on the top plate 61, the air pump 71 can be controlled to operate through the exhaust pipe 72 to generate negative pressure at the suction end 73, thereby sucking the profile 100 and fixing the profile 100 to prevent the position of the profile 100 from shifting when bending.

[0044] like Figure 13-Figure 15 As shown, a conversion mechanism is also included, which includes a drive motor 81, a connecting seat 82, an electric push rod 83 and a fixed block 84. The drive motor 81 is embedded at the bottom of the adjustable limit block 41 on the right side, and the connecting seat 82 is connected to the output shaft of the drive motor 81. The electric push rods 83 are installed on the rear and right sides of the connecting seat 82. The telescopic rods of the two electric push rods 83 are connected to the fixed blocks 84. The operation of the electric push rods 83 can drive the fixed blocks 84 to resist the profile 100, thereby assisting in fixing the profile 100.

[0045] After the profile 100 is bent once, when it is necessary to control the profile 100 to rotate ninety degrees, the telescopic rod of cylinder 2 63 can be controlled to extend to drive the connecting frame 62 to move downward, thereby driving the top plate 61 and the profile to move downward, so that the top height of the profile is lower than the bottom of the adjustable limit block 41, and then the telescopic rods of the two electric push rods 83 are controlled to extend to drive the two fixed blocks 84 to respectively press against the two sides of the profile 100, and then the driving motor 81 is controlled to drive the connecting seat 82 to rotate ninety degrees, thereby driving the profile 100 to rotate ninety degrees through the fixed block 84, so as to realize the function of automatically adjusting the angle of the profile 100, which is more convenient to operate.

[0046] like Fig.16 As shown, it also includes a pushing mechanism, which includes a slider 91, a pushing rack 92, a rack 93, a reduction motor 94 and a gear 95. The slider 91 is slidably connected to the right side of the guide track 3, and the pushing rack 92 is connected to the front side of the slider 91. The reduction motor 94 is installed on the top of the pushing rack 92, and the gear 95 is connected to the output shaft of the reduction motor 94. The rack 93 is connected to the front side of the top of the support plate 13, and the gear 95 is meshed with the rack 93, so that the operation of the reduction motor 94 can drive the slider 91 to move through the gear 95 and the rack 93.

[0047] When it is necessary to push the profile 100 to move, the gear 95 can be driven to rotate by the reduction motor 94. When the gear 95 rotates, it can drive the slider 91 to move to the left by engaging with the rack 93. When the slider 91 moves, it can drive the pusher rack 92 to move. When the pusher rack 92 moves, it can automatically push the profile 100 to move, and the overall operation is more convenient.
