Description

Technical Field

[0001] The utility model belongs to the technical field of aluminum alloy plate production, in particular to a bending device for aluminum alloy plate production. Background Art

[0002] Aluminum alloy plate is an industrial building material. It is used in various industries according to different materials. It can be divided into two categories according to the surface treatment method: non-painted products and painted products. Aluminum alloy plates have a wide range of uses. Different uses have different requirements for the shape of aluminum alloy plates. The shape of aluminum alloy plates needs to be changed by bending and other methods. Therefore, a bending device is needed to bend the aluminum alloy plates.

[0003] Among them, after searching, it was found that there is an application number CN202222056367.8, which discloses a sheet bending mechanism, including a workbench, the top surface of which is fixedly installed with four support columns, and the top surface of the support columns is fixedly installed with a support plate, which is provided with a pressure plate. After the staff feeds the sheet onto the bending plate through the feeding plate, the nut is tightened to make the pressure plate press down the sheet, and the rubber block under the pressure plate prevents damage to the sheet. After the pressure plate fixes one end of the sheet, the cylinder is started to drive the bending block to bend the sheet. After the bending is completed, the staff loosens the nut so that the pressure plate is bounced up by the spring and takes out the bent sheet, preventing the sheet from being easily offset before bending and affecting the bending effect. By setting connecting bolts, according to the required bending degree, the staff loosens the connecting bolts and takes out the connecting bolts, which is convenient for the staff to disassemble the bending plate and replace different bending plates.

[0004] However, after research, it was found that the device is only suitable for bending small plates. For longer aluminum alloy plates, the bending process using this device is relatively cumbersome and inconvenient to use. It is not easy to perform continuous bending on longer plates. There is no automatic unloading structure and manual unloading is required, which increases the labor intensity of the staff. Only one bend can be processed at a time, the processing efficiency is low, it is not convenient to automatically adjust the bending position, and it is not flexible enough to use. Utility Model Content

[0005] The purpose of the utility model is to provide a bending device for aluminum alloy plate production in order to solve the above-mentioned problems of inconvenience in use, difficulty in continuous bending of longer plates, and lack of automatic unloading structure.

[0008] Among them, the bending mechanism includes a screw slide A, a limit frame, a screw slide B, a hydraulic telescopic rod and a bending forming plate.

The hydraulic telescopic rod is installed below the matching slider of the screw slide B, and a bending forming plate is fixedly installed at the end of the hydraulic telescopic rod.

The positioning plate 1022 pushes the aluminum alloy plate to straighten the aluminum alloy plate. The two positioning plates 1022 are clamped on both sides of the aluminum alloy plate to position the aluminum alloy plate so that the center line of the aluminum alloy plate corresponds to the center line of the support frame 1. During the movement of the aluminum alloy plate, the ball 1023 rolls at the same time, reducing the friction between the aluminum alloy plate and the positioning plate 1022, making the movement of the aluminum alloy plate smoother.

[0028] The electric cylinder 1011 extends, driving the connecting frame 1012 to move downward, so that the conveying roller B104 below the connecting frame 1012 contacts the upper surface of the aluminum alloy plate. Then the motor A1031 and the motor B1041 work, driving the conveying roller A103 and the conveying roller B104 to rotate in the opposite direction. The conveying roller A103 and the conveying roller B104 jointly clamp the aluminum alloy plate and move it slowly.

[0029] Reference Figure 1-4 In this embodiment, the electric cylinder 1011, the servo electric cylinder 1021, the motor A1031, the motor B1041, the screw slide A2, and the screw slide B202 are all electrically connected to the external power supply through the switch panel, and the hydraulic telescopic rod 2021 is connected to the external hydraulic pump.

The two positioning plates 1022 are clamped on both sides of the aluminum alloy plate to position the aluminum alloy plate so that the center line of the aluminum alloy plate corresponds to the center line of the support frame 1, and then the electric cylinder 1011 extends, with The connecting frame 1012 is moved downward, so that the conveying roller B104 below the connecting frame 1012 contacts the upper surface of the aluminum alloy plate. Then the motor A1031 and the motor B1041 work to drive the conveying roller A103 and the conveying roller B104 to rotate in the opposite direction. The conveying rollers A103 and B104 clamp the aluminum alloy plate together and move slowly.
