Description

Technical Field

[0001] This utility model relates to the field of radiator accessory manufacturing technology, and in particular to an automatic forming device for automotive radiator fins. Background Technology

[0002] Radiator fins are thin, sheet-like metal attachments added to the radiator base tube. They are mainly used to enhance heat transfer. These fins can increase heat dissipation efficiency by increasing the heat dissipation area. Fins can be made of materials such as steel strip, stainless steel strip, copper strip, and aluminum strip. Common base tube materials include steel pipe, stainless steel pipe, and copper pipe.

[0003] A Chinese patent with publication number CN214264055U discloses a follow-up cutting device for automotive radiator fins. This utility model ensures that the cutting blade and the fin are relatively stationary along the discharge direction when the blade is lowered. Therefore, during the cutting process, the fixed blade and the movable blade will not exert pulling or squeezing forces on the fins along the discharge direction. This method not only reduces the force on the cutting blade and extends its service life, but also avoids the fins being pulled and squeezed, thus improving the processing accuracy of the product. However, the above patent still has shortcomings. The clamping and fixing mechanism in the above patent cannot clamp radiator fins of different sizes, and it is necessary to spend time replacing the clamping and fixing mechanism, resulting in low work efficiency. Therefore, we propose an automatic forming device for automotive radiator fins to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide an automatic forming device for automotive radiator fins to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An automatic radiator fin forming device for automobiles includes a worktable. Two symmetrical rotary motors are fixedly mounted on the upper surface of the worktable. Eccentric discs are fixedly connected to the output ends of both rotary motors. Connecting rods are hinged to the front sides of both eccentric discs via pins. Symmetrical L-shaped plates are provided on the upper surface of the worktable. Movable seats are fixedly connected to the opposite sides of the two L-shaped plates. The interiors of the two movable seats are hinged to the adjacent ends of the two connecting rods via pins. Springs are fixedly connected to the bottom surfaces of both L-shaped plates. Positioning blocks are fixedly connected to the bottom ends of both springs. Two sets of fixing blocks are fixedly connected to the upper surface of the worktable. Slide rails are fixedly connected to the outer surfaces of both sets of fixing blocks. Electric sliders are slidably connected to the outer surfaces of both slide rails. A cutting frame is fixedly connected to the upper surfaces of both electric sliders. Symmetrical electric lifting rods are fixedly connected to the bottom surfaces of the cutting frame. A mounting plate is fixedly connected to the output ends of both electric lifting rods. A blade is fixedly connected to the bottom surface of the mounting plate.

[0007] In a further embodiment, the bottom surface of the workbench is fixedly connected to two sets of support legs, and the bottom ends of the two sets of support legs are fixedly connected to support bases.

[0008] In a further embodiment, two sets of spring telescopic rods are fixedly connected to the bottom surface of the mounting plate, and pressure plates are fixedly connected to the bottom ends of both sets of spring telescopic rods.

[0009] In a further embodiment, a control panel is fixedly installed on the left side of the workbench, and the control panel is electrically connected to the electric slider, the electric lifting rod and the rotary motor respectively through wires.

[0010] In a further embodiment, the upper surface of the workbench is provided with a sliding groove, and symmetrical T-shaped blocks are slidably connected inside the sliding groove. The upper surfaces of the two T-shaped blocks are connected to the bottom surface of the L-shaped plate.

[0011] In a further embodiment, the two positioning blocks have chamfered edges on their sides that are close to each other, and telescopic rods are fixedly connected to the bottom surfaces of the two L-shaped plates. The two telescopic rods are located inside the springs, and the bottom ends of the two telescopic rods are connected to the upper surfaces of the positioning blocks.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This device utilizes a rotary motor, an eccentric disc, a connecting rod, and a movable seat. The rotating eccentric disc moves the movable seat via the connecting rod, allowing the L-shaped plate to clamp radiator fins of different sizes. Through the cooperation of the L-shaped plate, spring, and positioning block, the L-shaped plate moves the positioning block to the upper part of the radiator fins. The spring force causes the positioning block to press down and position the radiator fins. This solves the problem in the aforementioned patent where the clamping and fixing mechanism could not clamp radiator fins of different sizes, requiring time to replace the clamping and fixing mechanism.

[0025] The working principle of this utility model is as follows:

[0026] During use, the operator first places the radiator fins on the workbench 1. Then, the rotary motor 17 drives the eccentric disk 7 to rotate. The eccentric disk 7 drives the movable seat 11 to move horizontally through the connecting rod 8, so that the L-shaped plate 9 clamps the radiator fins. At the same time, due to the elastic force of the spring 21, the positioning block 22 presses down on the radiator fins to position them. Then, the electric slider 2 moves to the designated position, and the electric lifting rod 12 drives the mounting plate 13 to move down. The pressure plate 16 first contacts the radiator fins, and at the same time, the spring telescopic rod 15 retracts inward. Then, the blade 14 cuts the radiator fins to shape them.
