The purpose of the utility model is to provide an aluminum alloy sheet bending device for the production of aluminum alloy doors and windows, so as to solve the problem proposed in the above background technology that the existing device does not have a fixing function when bending the aluminum alloy sheet, which easily causes the aluminum alloy sheet to shift when bent during use, affecting the bending accuracy of the aluminum alloy sheet, and seriously affecting the subsequent production quality of aluminum alloy doors and windows, and certain improvements are needed.

To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an aluminum alloy sheet bending device for the production of aluminum alloy doors and windows, comprising a bending table, an operating hole is provided on the bending table, two rotating shafts are relatively rotatably installed in the operating hole, a fixed seat and an auxiliary frame are respectively fixedly installed on the outer surfaces of the two rotating shafts, a plurality of L-shaped support rods are slidably installed on the fixed seat, the ends of two L-shaped support rods on the same side are fixedly installed with the same fixed plate, a fixed driving mechanism is provided on the fixed seat, a plurality of auxiliary rollers are rotatably installed in the auxiliary frame, a mounting frame is fixedly installed on the upper surface of the bending table, an electric push rod is fixedly installed on the mounting frame, an opening is provided on the mounting frame, the piston end of the electric push rod passes through the opening and is fixedly installed with a mounting plate, and a bending head is detachably installed on the lower surface of the mounting plate.

The above scheme is adopted, by setting a fixed driving mechanism, which drives several L-shaped support rods to move during use. When the L-shaped support rods move, they drive the corresponding fixed plates to fix the aluminum alloy plates. By setting auxiliary rollers and auxiliary frames, the other part of the aluminum alloy plates is auxiliary supported to prevent the aluminum alloy plates from getting stuck during bending. By setting an electric push rod, when the electric push rod is started, it drives the mounting plate and the bending head to move downward to support the bending part of the aluminum alloy plates. With the two rotating shafts, when the two rotating shafts rotate relative to each other, they drive the fixed seat and the auxiliary frame to be relatively close to each other to bend the aluminum alloy plates. At the same time, when bending, the bending angle is precisely controlled according to the movement angles of the fixed seat and the auxiliary frame. The aluminum alloy plates are fixed as a whole during bending, and the bending angle is controlled at the same time. The overall bending accuracy is high, which makes the production quality of aluminum alloy doors and windows higher in the future.

By adopting the above scheme, motor 2 is set up. When motor 2 is started, it drives the bidirectional screw to rotate. When the bidirectional screw rotates, it drives the two drive plates to move relative to each other. When the two drive plates move relative to each other, the drive shaft and the drive hole drive the horizontal plate to move up and down. When the horizontal plate moves up and down, the corresponding fixed plate is moved up and down through the L-shaped support rod, thereby realizing the function of fixing and unlocking plates of different thicknesses, thereby ensuring the bending accuracy of the aluminum alloy plates during the bending process.

As a preferred embodiment, two limit rods are fixedly installed in the fixing seat, and the two driving plates are slidably installed on the outer surfaces of the two limit rods.

By adopting the above solution, by setting the limit rod, the limit and guiding function of the two drive plates is achieved, thereby ensuring the stability of the structural operation.

By setting the motor 11, the motor 11 drives one of the rotating shafts 2 to rotate when it is started, and the transmission effect of the two gears 12 is used to drive the two rotating shafts 2 to move relatively synchronously. When the rotating shaft 2 moves, it drives the fixed seat 3 and the auxiliary frame 4 to move synchronously, so as to achieve the bending effect of the aluminum alloy sheet.

A plurality of L-shaped support rods 5 are slidably mounted on the fixed seat 3, and the ends of the two L-shaped support rods 5 on the same side are fixedly mounted with the same fixed plate 6. A fixed driving mechanism is provided on the fixed seat 3, and the fixed driving mechanism includes a second motor 13 fixedly mounted on the side of the fixed seat 3. A bidirectional screw 14 is rotatably mounted in the fixed seat 3, and one end of the bidirectional screw 14 extends to the outside of the fixed seat 3 and is fixedly connected to the output shaft of the second motor 13. A driving plate 15 is threadedly mounted on the two sections of the thread of the bidirectional screw 14, and a driving shaft 16 is rotatably mounted on the front and rear sides of the driving plate 15. The two L-shaped support rods 5 on the same side are fixedly mounted with the same cross plate 17 at one end located in the fixed seat 3, and two driving holes for the driving shaft 16 are provided on the cross plate 17. Two limit rods 18 are fixedly mounted in the fixed seat 3, and the two driving plates 15 are slidably mounted on the outer surfaces of the two limit rods 18.

By setting the motor 2 13, the motor 2 13 drives the bidirectional screw 14 to rotate when it is started, and the bidirectional screw 14 drives the two driving plates 15 to move relative to each other when it rotates. When the two driving plates 15 move relative to each other, the driving shaft 16 and the driving hole drive the cross plate 17 to move up and down. When the cross plate 17 moves up and down, the L-shaped support rod 5 makes the corresponding fixed plate 6 move up and down, so as to realize the function of fixing and unlocking plates of different thicknesses, and ensure the bending accuracy of aluminum alloy plates in bending processing. By setting the limit rod 18, the limiting and guiding function of the two driving plates 15 is realized, and the stability of the structure operation is ensured.

A rubber anti-skid pad 19 is fixedly installed on the lower surface of the fixing plate 6. By providing the rubber anti-skid pad 19, an anti-skid effect is achieved between the fixing plate 6 and the aluminum alloy plate, and at the same time, the surface of the aluminum alloy plate is prevented from being worn and scratched when fixed.

A number of auxiliary rollers 21 are rotatably installed in the auxiliary frame 4, a mounting frame 7 is fixedly installed on the upper surface of the bending table 1, an electric push rod 8 is fixedly installed on the mounting frame 7, an opening is opened on the mounting frame 7, the piston end of the electric push rod 8 passes through the opening and a mounting plate 9 is fixedly installed, a bending head 10 is detachably installed on the lower surface of the mounting plate 9, two guide rods 20 are fixedly installed on the upper surface of the mounting plate 9, the two guide rods 20 are both slidably installed on the mounting frame 7, and by setting the guide rods 20, the movement of the mounting plate 9 is limited and guided, thereby ensuring the stability of the movement of the bending head 10.

Working principle: When in use, first place the aluminum alloy plate to be processed on the auxiliary frame 4 and the fixed seat 3, then adjust the plate according to the bending position, and start the motor 2 13 after adjustment. When the motor 2 13 is started, it drives the bidirectional screw 14 to rotate. When the bidirectional screw 14 rotates, it drives the two driving plates 15 to move relatively close. When the two driving plates 15 move relative to each other, the driving shaft 16 and the driving hole drive the cross plate 17 to move downward. When the cross plate 17 moves downward, the L-shaped support rod 5 is used to make the corresponding fixed plate 6 move downward to fix the plate. After fixing, start the electric pusher Rod 8, when the electric push rod 8 is started, it drives the mounting plate 9 and the bending head 10 to move downward and abut against the surface of the plate, and then starts the motor 11. When the motor 11 is started, it drives one of the rotating shafts 2 to rotate, and uses the transmission effect of the two gears 12 to drive the two rotating shafts 2 to move relatively synchronously. When the rotating shaft 2 moves, it drives the synchronous movement of the fixed seat 3 and the auxiliary frame 4. When the fixed seat 3 and the auxiliary frame 4 move, they cooperate with the bending head 10 to bend the plate. After the bending is completed, start the motor 11 to unlock the plate, and finally start the electric push rod 8 and the motor 2 13 to work in the reverse direction to reset the device.
