Description

Technical Field

[0001] The utility model relates to a bending device, in particular to a bending device for aluminum profiles. Background Art

[0002] In the prior art, there are two ways to bend aluminum profiles: manual bending and bending with bending tools. Manual bending has low efficiency and low bending quality. There is also a problem of high labor intensity for operators. A Chinese patent with application number CN202320025738.8 provides a patent for an aluminum profile bending device. The solution rotates a first hand-tightened screw and a second hand-tightened screw to respectively drive an upper support plate and an upper force plate to rise and fall, insert the left side of the aluminum profile between the upper support plate and the lower support plate, insert the right side of the aluminum profile between the upper force plate and the lower force plate, and then The position to be bent is located between the supporting assembly and the bending assembly. The servo motor drives the rotating shaft to rotate the U-shaped plate. When the U-shaped plate rotates, the aluminum profile is bent under the action of the lower force plate and the upper force plate. This solution replaces the manual bending method, which not only improves the efficiency but also reduces the labor intensity of the operator. However, the bending position of this solution is located between the supporting assembly and the bending assembly. After the first bending is completed, it is not convenient to bend other parts of the aluminum profile again. In addition, the positions of the supporting assembly and the bending assembly are fixed and cannot be adjusted, so the applicability is not high when used.

[0045] The optimal working principle of the utility model is as follows:

[0046] The aluminum profile 99 to be bent is placed on the first bending unit 2, and passed between the bending rod 13 and the positioning cylinder 18, and the clamping head 51 is pushed forward by the clamping cylinder 19 (the clamping cylinder 19 is not connected to the rotating seat 11, and when the clamping cylinder 19 pushes the clamping head 51 forward, the lower end of the clamping cylinder 19 does not fit with the upper end of the rotating seat 11), so as to cooperate with the positioning cylinder 18 to clamp and position the aluminum profile 99, and then the operator rotates the rotating seat 11 by holding the handle 12, and the bending rod 13 rotates with the rotation of the rotating seat 11, and the aluminum profile 99 is bent by the rotation of the bending rod 13. After the bending is completed, the clamping head 51 is retracted, and then the positioning cylinder 18 and the clamping cylinder 19 are retracted upward by the lifting cylinder 16 to take out the aluminum profile 99;

After the bending is completed, the positioning cylinders 18 and the tightening cylinders 19 on the first bending unit 2 and the fourth bending unit 6 are retracted upward by the lifting cylinder 16. At this time, the positioning cylinders 18 and the tightening heads 51 on the first bending unit 2 and the fourth bending unit 6 no longer limit the two sides of the aluminum profile 99, and then the aluminum profile 99 is bent again by the second bending unit 3 and the third bending unit 5, and the positioning cylinders 18 and the tightening cylinders 19 of the second bending unit 3 and the third bending unit 5 are pulled up to take out the bent aluminum profile;
