Description

Technical Field

[0001] The present invention belongs to the technical field of profile bending, and provides a bending device capable of controlling the profile conveying position, adapting to different profile specifications, and adjusting the angle and position of the bending die, and in particular relates to a bending forming device for aluminum alloy profiles. Background Art

[0002] Aluminum alloy profiles have been widely used in many fields such as construction, automobiles, aerospace, electronic equipment, etc. due to their many excellent properties such as light weight, high strength, corrosion resistance, and recyclability. In the processing of aluminum alloy profiles, bending forming is a key processing technology, and its processing quality directly affects the performance and appearance of aluminum alloy profile products.

[0003] At present, there are many shortcomings in the existing aluminum alloy profile bending equipment. In the profile conveying link, the conveying mechanism of many equipment is relatively simple, and it is difficult to accurately control the conveying speed and position of the aluminum alloy profile, resulting in low positioning accuracy of the profile during bending, which in turn affects the accuracy and consistency of the bending. For aluminum alloy profiles of different specifications, the existing conveying mechanism often lacks effective adjustment means and cannot meet diverse production needs.

[0004] In terms of bending mechanism, traditional bending equipment mostly uses fixed bending molds and bending angle settings, which have poor flexibility. When it is necessary to process aluminum alloy profiles of different shapes and angles, it is usually necessary to frequently replace the bending molds, which not only increases labor intensity and production costs, but also reduces production efficiency. The existing bending equipment does not accurately control the pressure of the profile during the bending process, which can easily lead to quality problems such as cracks and deformation of the aluminum alloy profile at the bending point, affecting the quality and service life of the product.

[0005] The existing aluminum alloy bending equipment also needs to be improved in terms of automation and intelligence. In actual production, operators need to perform a lot of manual adjustments and monitoring work, which is not only labor-intensive, but also difficult to ensure the stability of the production process and the consistency of product quality. With the rapid development of the manufacturing industry, higher requirements are put forward for the automation, intelligence, high precision and high efficiency of aluminum alloy bending equipment.

[0006] Therefore, the development of an aluminum alloy profile bending and forming equipment that can accurately convey aluminum alloy profiles, flexibly adjust bending molds and angles, accurately control bending pressure, and has a high level of automation and intelligence has important practical significance and broad market prospects.

Finally, check whether the position of the follower shaft 214 is accurate to ensure that it can effectively guide the aluminum alloy profile into the bending die 201.

[0026] Workflow: S1. Equipment preparation stage The operator turns the adjustment knobs on the first profile specification adjustment seat 107 and the second profile specification adjustment seat 109 according to the cross-sectional size of the aluminum alloy profile to be processed, and accurately adjusts the initial spacing between the upper conveying wheel 106 and the lower conveying wheel 105 through the screw nut transmission principle to make it slightly larger than the profile height, turns on the control switch of the electric telescopic rod 104, and sets the descending stroke to ensure that the profile can be clamped stably in the future; According to the bending process requirements, the target bending angle is input into the control system, and the servo motor of the driver 209 rotates precisely according to the instruction, and drives the follower pinion 3 215 to rotate through the flat key. The follower pinion 3 215 engages with the semicircular gear ring 203, and drives the semicircular gear ring 203 and the bending mold 201 connected thereto to rotate precisely to the target angle around the axis of the rotating seat 210. According to the bending position requirements of the profile on the mold, the extension length of the telescopic cylinder 208 is set in the control system. The cylinder action pushes the nut of the linear drive screw 206 to move horizontally, and the nut engages with the arc-shaped transmission gear ring 204, driving the bending mold 201 to translate to the specified position.

[0027] S2, Profile conveying stage Place the aluminum alloy profile horizontally between the lower conveying wheel 105 and the upper conveying wheel 106. After confirming the correct position again, start the electric telescopic rod 104, which extends and pushes the connecting rod 102, so that the upper conveying wheel 106 descends and fits the profile tightly, achieving stable clamping; The driver 118 is turned on, and the motor output shaft drives the large gear 114 to rotate at a high speed through the flat key. The large gear 114 is meshed with the crescent gear 113 and the crescent gear 2 115 at the same time to transmit power. The crescent gear 113 drives the follower pinion 112, and the crescent gear 2 115 drives the follower pinion 2 116, so that the lower conveying wheel 105 and the upper conveying wheel 106 rotate synchronously and at a uniform speed, and the profile is smoothly conveyed to the adjustable specification bending mechanism 2 at the set linear speed.

[0028] S3, Profile Bending Stage Before the profile reaches the bending die 201, the control system once again detects and compares the current angle and position of the bending die 201 with the preset values. If there is a deviation, the driver 209 and the telescopic cylinder 208 will make slight adjustments to ensure that the bending die 201 is in the best working state; When the front end of the profile contacts the follower shaft 214, the follower shaft 214 guides the profile to accurately enter the bending die 201. Under the buffering effect of the pressure reducing spring 205, the bending die 201 gradually applies pressure to the profile to bend it. During this process, the operator can adjust the position of the top block 212 on the angle adjustment seat 211 and use the roller 213 to accurately change the subtle angle of the bending die 201 to ensure the bending accuracy.

[0029] S4, Finished product unloading stage After the bending is completed, the electric telescopic rod 104 contracts, driving the upper conveying wheel 106 to rise and release the profile, and the conveying linkage mechanism 1 briefly reverses to push the bent profile backward for a distance; The operator manually takes the profiles out of the equipment's working area and places them on a designated collection rack. For production lines with a higher degree of automation, a robotic arm or conveyor belt will directly transfer the finished products to the subsequent processing area or packaging area.
