Description

Technical Field

[0001] The invention relates to the technical field of arc bending devices, in particular to an arc bending device for aluminum profiles. Background Art

[0002] Existing aluminum profiles are widely used in various fields because of their convenient processing and manufacturing, and are not easy to rust. However, although the processing method of aluminum profiles is simpler than that of other metal materials, such as steel, aluminum profiles are metals after all, and have certain strength and hardness. To make the strip aluminum profiles into a certain curvature, special bending equipment is required. The bending equipment currently used is generally large-scale equipment with high cost and high degree of automation. It is suitable for large-scale sanitary ware manufacturers. However, for some small and medium-sized sanitary ware manufacturers, in order to reduce production costs, most of them adopt manual bending methods, which are labor-intensive, low-efficiency, and poor bending quality of aluminum profiles. At the same time, the bending molds of existing bending devices are mostly fixed on the workbench. When the profile needs to be bent into different curvatures, it is very troublesome to replace different bending molds. In addition, the existing bending devices are prone to deviation during the bending process of the profiles, which is very easy to cause damage to the profiles. Summary of the invention

[0019] Compared with the prior art, the beneficial effects of the present invention are: the arc bending device of the aluminum profile has the following advantages.

[0020] 1. Insert the profile from right to left into the gap between the three rotating shafts, and make the profile located between the three limit rings and the three connecting plates. After placement, control the three third motors to rotate forward by controlling the switch group. The three third motors rotate forward to drive the profile to move to the left.

By setting the above device, the present invention can perform arc bending very conveniently.

[0021] 2.

[0022] 3. When it is necessary to bend profiles of different widths, the first motor and the second motor are controlled in sequence by the control switch group according to the required bending angle. The first motor drives the bidirectional screw to rotate, and the rotation of the bidirectional screw drives the two moving blocks to gradually approach each other. The two moving blocks gradually approach each other and drive the left and right rotating shafts to gradually approach each other. After the left and right rotating shafts gradually approach each other to a suitable position, the first motor is turned off, and the second motor drives the screw to rotate. The rotation of the threaded rod drives the moving plate to move. The movement of the moving plate drives the middle rotating shaft to move up and down. After the middle rotating shaft moves up and down to a suitable position, the second motor is turned off, and then the profile that needs to be bent is placed between the upper and lower three rotating shafts again, and then the three third motors are turned on to rotate the three rotating shafts to bend the profile. By setting the above device, the present invention can bend the profile into arcs of different angles.

[0023] 4. Before bending different profiles, first observe the width of the profile, and then rotate all the threaded columns forward according to the width of the aluminum profile. The forward movement of all the threaded columns drives the three limit rings to move forward. During this process, the user observes the distance between the three limit rings and the three connecting plates. When the distance between the two is the same as the width of the profile, stop rotating the threaded columns. By setting the above device, the present invention can effectively avoid the deviation of the profile when bending. BRIEF DESCRIPTION OF THE DRAWINGS
