Abstract

This invention relates to the field of aluminum alloy plate equipment technology, and discloses an automatic receiving device for bending aluminum alloy plates. The device includes a bending device, with a first telescopic device movably connected to the top of the front of the bending device, and a base plate movably connected to the bottom of the first telescopic device. Semicircular blocks are fixedly connected to both sides of the base plate on the front of the bending device. This invention, by incorporating ball bearings, clamping blocks, and guide rails, facilitates the transfer of the aluminum alloy plate to one side of the guide rail after bending via the second wheel groove during the bending process. The bending degree of the aluminum alloy plate is determined by the smoothness of the ball bearing surface and then moves upward along the guide rail, where the clamping blocks fix the aluminum alloy plate surface. This reduces the safety hazards caused by manual operation after bending the aluminum alloy plate, and allows for efficient and safe receiving. Furthermore, the guide rails and clamping blocks can hold one side of the aluminum alloy plate, preventing poor clamping at the tail of the bending process from affecting the bending degree at the tail end.

Description

Technical Field

[0001] This invention relates to the field of aluminum alloy plate equipment technology, and more specifically to an aluminum alloy plate bending and splicing device. Background Technology

[0002] An aluminum alloy sheet bending device is a device that bends aluminum alloy sheets to the required curvature, making the bent aluminum alloy sheets easier to install in some decoration industries. Existing aluminum alloy sheet bending devices consist of three rollers, a transmission device, and a main control unit, and are widely used in the aluminum alloy sheet processing industry.

[0003] The aluminum alloy sheet bending device first sets the parameters in the main control machine, then the aluminum alloy sheet is conveyed into the rollers through the conveying device and bent according to the corresponding parameters to form the corresponding curvature of the aluminum alloy sheet, and then placed.

[0004] After the aluminum alloy sheet is bent into shape, the receiving of the sheet is done manually, which poses certain safety hazards. When bending large aluminum alloy sheets, a large amount of labor costs are required. During the bending process, there will be repeated bending, and it is impossible to fix the sheet manually. This will cause the aluminum alloy sheet to be bent too long, resulting in deviation of the unbent part. After the aluminum alloy sheet is bent into shape, it is not properly shaped and is randomly discarded, which will damage the surface of the aluminum alloy sheet and affect the pass rate.

[0005] Therefore, an aluminum alloy sheet bending and splicing device is needed. Summary of the Invention

A sliding ball 17 is provided on one side of the bead groove 124. The outer surface of one side of the sliding ball 17 is movably connected to the guide rail 12 through the inner wall of the bead groove 124.

The long shaft 16 is movably connected to the other side of the clamping block 162 through the inner wall of the second ring sleeve 161.

[0031] In this embodiment, it should be specifically explained that the movable connection of the sliding ball 17 on the inner wall of the ball groove 124 allows the curved aluminum alloy plate to quickly enter the interior of the guide rail 12 through the surface of the sliding ball 17, preventing the aluminum alloy plate from being unable to enter the interior of the guide rail 12. Then, the moving clamping block 162 drives the second ring sleeve 161 to rotate on the outer surface of the long shaft 16, so that the other side of the long shaft 16 is movablely connected to the slot 121 to clamp the aluminum alloy plate, preventing the aluminum alloy plate from falling and fixing the tail of the aluminum alloy plate to a certain extent and reducing the offset during bending.

[0032] Reference Figure 5 A ring groove 132 is provided on the other side of the strip plate 13. A round rod 14 is provided on one side of the ring groove 132. A first ring sleeve 141 is provided on one side of the round rod 14. A sleeve wall 142 is provided inside one side of the first ring sleeve 141. The round rod 14 is movably connected to one side of the first ring sleeve 141 through the inner wall of the sleeve wall 142. A shaft hole 143 is provided at the top of the round rod 14. A main motor housing 18 is provided at the top of the shaft hole 143. A transmission shaft 181 is movably connected to the bottom of the main motor housing 18. The outer surface of the bottom of the transmission shaft 181 is movably connected to the round rod 14 through the shaft hole 143. The strip plate 13 is movably connected to the round rod 14 and the outer surface of the first ring sleeve 141 through the inner wall of the ring groove 132.

[0033] In this embodiment, it should be specifically noted that when the chassis 15 is pushed by the push pad 192, the transmission shaft 181, the first ring sleeve 141, and the strip plate 13 are rotated by the transmission of the main motor box 18, which can rotate the aluminum alloy plate on one side of the guide rail 12 to prevent it from colliding with the surface of the bending device 1.

[0034] Reference Figure 6 and Figure 7 A square hole 303 is provided on one side of the long plate 3, and a fixed block 19 is provided on one side of the square hole 303. The outer surface of one side of the fixed block 19 is movably connected to the long plate 3 through the inner wall of the square hole 303. A second telescopic device 191 is provided on the other side of the long plate 3. The outer surface of one side of the second telescopic device 191 is movably connected to the fixed block 19 through the inner wall of the square hole 303. A push pad 192 is provided on one side of the second telescopic device 191. A plate hole 193 is provided in one side of the push pad 192. The outer surface of one side of the second telescopic device 191 is movably connected to the push pad 192 through the inner wall of the plate hole 193. A plate groove 3021 is provided inside the groove 302. A push pad 192 is provided on one side of the plate groove 3021. The outer surface of one side of the push pad 192 is movably connected to the long plate 3 through the inner wall of the plate groove 3021.

[0035] In this embodiment, it should be specifically explained that after the aluminum alloy plate is bent, the chassis 15 drives the pulley 151 to move along the inner wall of the groove 302 to one side of the push pad 192. The second telescopic device 191 then extends and retracts to push the push pad 192, causing the chassis 15 to move into the interior of the groove 101. This reduces the need for manual straightening by employees and further improves work efficiency.

[0036] Reference Figure 8 and Figure 3 The second wheel groove 112 on the front of the bending device 1 is on the same horizontal plane as the guide rail 12. The L-shaped groove 301 is connected to the corresponding groove 101 on one side. The chassis 15 is connected to the L-shaped groove 301 through the mating groove 101.

[0037] In this embodiment, it should be specifically noted that the second wheel groove 112 and the guide rail 12 are on the same horizontal plane, which can better facilitate the transfer of the aluminum alloy plate to the inside of the guide rail 12 after bending. The L-shaped groove 301 connects to the groove 101 and the chassis 15, which reach the inside of the groove 101 through the L-shaped groove 301, preventing tilting when the chassis 15 is pushed by the push pad 192.

[0038] Working principle of this invention:

[0039] S1. When using the automatic aluminum alloy sheet bending receiving device, before use, the operator first inputs the instruction data into the main control machine 2, and then transmits the instruction to the bending device 1 through the wire 201. The aluminum alloy sheet is then placed on the surface of the second wheel groove 112 for transmission. The bending device 1 controls the first telescopic device 5 to make the base plate 6 drive the first roller 901 to move up and down. The aluminum alloy sheet is bent to a certain degree through the corresponding parameters. During the bending process, the aluminum alloy sheet is blocked by the stop bar 8 on one side of the semi-circular block 7 to prevent the aluminum alloy sheet from shifting during the bending process, resulting in the aluminum alloy sheet surface not being bent.

[0040] S2. When using this automatic aluminum alloy sheet bending receiving device, firstly, the clamping block 162 is rotated on the outer surface of the long shaft 16 via the second ring 161 on one side, and the other side of the clamping block 162 is movably connected to the corresponding slot 121. Then, the drive motor device 152 drives the chassis 15, causing the chassis 15 to move the pulley 151 and the round rod 14. The outer surface of the chassis 15 moves along the inner wall of the groove 302 in the corresponding direction until it is at the same level as the second wheel groove 112. After the first roller 901 and the second wheel groove 112 bend the front part of the aluminum alloy sheet, it is conveyed out and placed along the guide rail 12. The aluminum alloy sheet slides along the inner wall of the ball groove 124 by the bending degree of the front part of the aluminum alloy sheet, so that the aluminum alloy sheet slides into the guide rail 12. Clamping blocks 162 are provided to bend the middle part of some excessively long aluminum alloy plates. The spacing of the clamping blocks 162 allows for secondary bending. The clamping of the aluminum alloy plate surface by one side of the clamping blocks 162 ensures good stability when bending the remaining tail of the aluminum alloy plate. After bending, the second telescopic device 191 on one side of the fixed block 19 pushes the chassis 15 to the inclined side of the corresponding angled conveyor 10. Through the transmission of the angled conveyor 10, the first telescopic device 5 moves to the other side of the angled conveyor 10 in the matching groove 101 and stops to effectively straighten it. During the transmission process, the operation of the main motor box 18 drives the rotation of the transmission shaft 181, which drives the round rod 14 to drive the first ring sleeve 141 to rotate the strip plate 13, so that the aluminum alloy plate surface faces outward to prevent collision with the bending device 1.
