Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of fin twisting devices, in particular to a fin twisting device used in the production of air-conditioning evaporators. Background Art
[0002] Fin processing is crucial in the production process of automobile air conditioning evaporators. Air conditioning evaporator fins are thin metal sheets installed between the evaporator pipes to increase the heat exchange area and promote heat exchange efficiency. In order to meet the needs of efficient heat exchange, these fins often need to be processed in a specific shape, such as twisting, to change the angle of the fins or enhance the turbulence effect on their surface, thereby optimizing air flow and heat exchange performance.
[0003] The function of the skew device is to adjust the angle of the fins through precise mechanical means to ensure that they can reach the required skew degree to ensure heat exchange efficiency and airflow dynamics. This process is usually completed before the fins are assembled on the evaporator. In specific operations, the skew device uses the upper and lower pressure plates and the special inclined surfaces processed on these pressure plates to implement the skew of the fins.
[0004] During the fin skew process, the upper and lower pressure plates apply pressure to the fins, while the inclined structure guides the fins to deform at a predetermined angle to achieve the desired skew effect. Ideally, the fins can be easily detached from the upper and lower pressure plates after skew. However, due to the characteristics of the metal material or the conditions during the processing, sometimes the fins may stick to the pressure plate after skew.
[0005] Usually, when the fins are stuck to the lower platen, the workers can remove the fins relatively easily due to the lower position of the lower platen. However, if the fins are stuck to the upper platen, the workers may encounter difficulties in removing them due to the higher height; this is not only time-consuming and labor-intensive, but may also increase safety risks during the operation.
[0006] Based on this, those skilled in the art have proposed a fin twisting device for use in the production of air-conditioning evaporators. Utility Model Content

The slide rod can slide inside the fixed sleeve, and the slide rod can squeeze the spring during the downward movement, thereby providing a reset force for the slide rod through the spring.

[0012] As a preferred embodiment, a longitudinal pressure plate is fixedly connected to the outer side of the lower pressure plate, the longitudinal pressure plate is used in conjunction with a contact plate, and a cross bar is fixedly connected between the two sliding bars.
[0013] Through the above technical means, the lower pressure plate can be lowered to drive the longitudinal pressure plate to be lowered, so that the longitudinal pressure plate comes into contact with the contact plate, thereby driving the slide bar to move downward.
[0014] As a preferred embodiment, a lifting plate is fixedly connected between the tops of the two sliding rods, a groove body is opened inside the upper pressure plate, connecting columns are equidistantly fixedly connected to the bottom of the lifting plate, the bottoms of the connecting columns extend into the interior of the groove body, a pushing plate is fixedly connected between the bottoms of the connecting columns, and pushing blocks are equidistantly fixedly connected to the bottom of the pushing plate.
[0015] Through the above technical means, the connection column is driven to descend by the descent of the slide rod, and then the push plate and the push block are driven to descend by the connection column.
[0016] As a preferred implementation, through slots are equidistantly formed at the bottom of the upper pressing plate, and the through slots are used in conjunction with the pushing blocks.
[0017] Through the above technical means, the pushing block will extend into the through slot during the descending process, and then can resist the fin workpiece, so that the workpiece can be removed.
[0018] As a preferred embodiment, the internal thread of the other connecting plate is connected to a screw rod, one end of the screw rod is rotatably connected to a limiting plate, and two optical rods are symmetrically fixedly connected to the outside of the limiting plate and located on the outside of the screw rod, and one end of the optical rod away from the limiting plate extends to the outside of the connecting plate and is slidably connected to it.
[0019] Through the above technical means, the limit plate can be controlled to move by twisting the screw rod, and the position of the fin workpiece can be controlled by the movement of the limit plate, thereby ensuring the accuracy of the fin installation.
[0020] Compared with the prior art, the advantages and positive effects of the utility model are:

During the descent process, the sliding rod drives the pushing block to extend into the through groove, and then pushes the fins to complete the separation. Compared with traditional equipment, the device avoids the problem of the fins sticking to the upper pressure plate during the extrusion process and being inconvenient to disassemble.

[0031] In summary: the hydraulic cylinder 4 can drive the lower pressure plate 2 to rise, and the rising of the lower pressure plate 2 cooperates with the upper pressure plate 1 to complete the twisting operation of the fins. The slide rod 8 can slide inside the fixed sleeve 7. The slide rod 8 can squeeze the spring 9 during the downward movement, and then the spring 9 provides the slide rod 8 with a reset force.
[0032] like Figure 1-Figure 4 As shown, the outer sides of the slide bars 8 are fixedly connected with connection blocks 10, and the connection blocks 10 are extended to the outer sides of the connection plates 5 through the slide grooves 6, and a contact plate 11 is fixedly connected between the outer sides of the two connection blocks 10;
[0033] In summary: the contact plate 11 can be fixed by providing the connecting block 10 .

[0035] In summary: the lowering of the lower pressure plate 2 can drive the longitudinal pressure plate 12 to move downward, so that the longitudinal pressure plate 12 comes into contact with the contact plate 11, thereby driving the slide bar 8 to move downward.

[0043] In actual use, first, the fin original is placed on the lower pressure plate 2, and then the lower pressure plate 2 can be driven to rise by the hydraulic cylinder 4. The rise of the lower pressure plate 2 cooperates with the upper pressure plate 1 to complete the twisting operation of the fin. After that, the lower pressure plate 2 is driven down by the descent of the hydraulic cylinder 4, and then the longitudinal pressure plate 12 is driven down, so that the longitudinal pressure plate 12 contacts with the contact plate 11, thereby driving the slide bar 8 to move downward, and the descent of the slide bar 8 drives the connecting column 16 to descend, and then the connecting column 16 drives the push plate 17 and the push block 18 to descend. The push block 18 will extend into the through groove 19 during the descent process, and then the fin workpiece can be resisted, thereby removing the workpiece.
