Description

Technical Field

[0001] This utility model belongs to the field of innovative technology in the automotive industry, and specifically relates to an integrated automatic bending device. Background Technology

[0002] Bending is a common metalworking technique used to bend metal materials into desired shapes and angles. By applying force, the metal material is bent or deformed along a specified bending line, creating parts and components of various shapes. Among these, a 90° bending angle is one of the most common and fundamental angle requirements, referring to precisely folding or bending the metal material at a 90° angle along an orthogonal direction. Some metal parts in automotive interior components require 90° bending using a clamping jaw for assembly. Current bending technology involves two steps: first, pre-pressing to a certain angle, and then applying pressure to the desired bending shape using a conforming mechanism. This invention provides an integrated automatic bending device that can bend metal parts in one step, forming them in one step, following a conforming trajectory, and offering flexible adjustments. Utility Model Content

[0029] The present invention will now be described in further detail with reference to the accompanying drawings, so that those skilled in the art can implement it based on the description.

[0030] like Figure 1-3 As shown, this utility model provides an integrated automatic bending device, which mainly includes: a cylinder 110, one end of which is fixedly connected to the bending machine body, and a piston 111 is provided inside the cylinder; the cylinder is a double-acting cylinder with two ports 170 that are in contact with compressed air; a sensor 112 is fixedly installed on the cylinder 110, and the sensor 112 is used to determine the position of the piston rod 111; a metal plate is fixedly installed at the other end of the cylinder 110, and the metal plate is fixed to the cylinder 110 with screws; a conformal body 120 is fixed to the metal plate with screws, and one end of the conformal body 120 is fixedly connected to the other end of the cylinder 110.

[0031] like Figure 4-5 As shown, the conformal body 120 is a hollow cylindrical body, detachably and fixedly connected to one end of the piston rod 111 extending from the cylinder barrel of the cylinder 110, and coaxially sleeved on the piston rod 111. A wedge mechanism 130 is fixedly installed inside the conformal body 120, with one end of the wedge mechanism 130 disposed within the conformal body 120 and fixedly connected to the piston rod 111. The wedge mechanism 130 includes a main body and a wedge portion. One end of the main body is disposed within the conformal body and fixedly connected to the piston rod; the other end of the main body is provided with a slider; the slider is inclined relative to the axis of the main body; the wedge portion is provided with a groove matching the slider, allowing the wedge portion to slide obliquely relative to the main body. The wedge mechanism 130 mainly clamps the workpiece by adjusting the position and angle of the wedge portion, thereby keeping the workpiece in a fixed position. When the wedge portion is adjusted to a certain position and angle, the friction between the workpiece and the clamping surface increases, resulting in good workpiece fixation. Meanwhile, the wedge mechanism has pressure equalization performance, which can apply pressure evenly and prevent the workpiece from becoming unstable.

[0032] The conformal body 120 has two symmetrical track grooves 150 at the end away from the metal plate, which are formed on the conformal body 120 and symmetrically arranged on both sides of the wedge mechanism; two guide shafts 140 are coaxially fixed on both sides of the wedge mechanism, the two guide shafts pass through the two track grooves one to one and can slide along the track, and one end of the guide shaft 140 is provided with a retaining spring to fix it axially in the track groove 150; the wedge mechanism 130 has two symmetrical connecting arms at the end away from the piston rod 111, and the two connecting arms are respectively arranged on the same side as the two track grooves 150; the two ends of the rotating wheel 160 are rotatably connected to the two connecting arms, and the connecting arms are provided with circular through holes, one end of the rotating wheel 160 passes through the circular through holes and is axially fixed by a retaining spring.

[0033] When compressed air flows in through one of the ports 170 of the cylinder 110, the piston rod 111 is pushed. The piston rod 111 is fixedly connected to the wedge mechanism 130 through a connector 180, thereby pushing the wedge mechanism 130 downward and transmitting force to the rotating wheel mechanism 160. A guide shaft 140 is mounted on the wedge mechanism. The guide shaft 140 slides with the track groove 150 on the conformal body, so that the rotating wheel 160 moves along the track groove after being subjected to force.

[0034] During the bending process, the product's upright claw is perpendicularly aligned with the rotating wheel 160. Compressed air flows into the cylinder 110 through one port 170, outputting pressure and pushing the piston rod 111. The piston rod 111 moves downward, pushing the slider of the wedge mechanism 130. After the slider and the wedge trajectory are completely aligned, the wedge mechanism 130 moves downward as a whole, causing the guide shaft 140 to move along the trajectory of the two track grooves 150 on the accompanying body. At the same time, the rotating wheel 160 pushes the product's upright claw to gradually deform along the trajectory of the track grooves 150, achieving the desired effect. The sensor 112 detects the position of the piston rod 111 and determines that the bending is complete. The compressed gas is output in the opposite direction and flows into the cylinder 110 from the other port 170, pulling the piston 111 back to its original position. The piston rod 111 drives the wedge mechanism 130 back to its original position, and the bending process is complete.

[0035] This utility model provides an integrated automatic bending device that uses a double-acting cylinder to achieve force or motion control in both forward and reverse directions, enabling one-step bending of product parts. It features stable and reliable operation, a simple structure, convenient maintenance, and the bending effect is not affected by product deformation, offering broad processability. The bending mechanism has a consistent structure and dimensions, achieving standardized design and manufacturing, thus saving costs. The pneumatic bending method allows for rapid adjustment of speed and pressure, resulting in short debugging time. Furthermore, the conformal body can be replaced according to the trajectory requirements, broadening its applicability.

[0036] Although the embodiments of this utility model have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for this utility model. For those skilled in the art, other modifications can be easily made. Therefore, without departing from the general concept defined by the claims and their equivalents, this utility model is not limited to the specific details and the illustrations shown and described herein.
