Description

Technical Field

[0001] This utility model belongs to the field of filter center tube processing technology, and in particular relates to a filter center tube compression molding device. Background Technology

[0002] A filter is a device used to filter impurities and purify fluids (such as air, fuel, engine oil, water, etc.). It is widely used in many fields such as automobiles, industrial equipment, and aerospace to ensure the normal operation of related systems and extend the service life of equipment. The filter center tube is one of the core components of the filter and is usually located in the center of the filter.

[0003] During the production of the filter center tube, after the perforated mesh is bent using a roller press, there is still a significant distance between the two ends. Subsequent welding requires a secondary closing, which is inconvenient for the welding operation. Furthermore, because the perforated mesh is not fully in place, it possesses a certain degree of expansion force, which can easily lead to subsequent weld detachment. Therefore, a filter center tube pressing and forming device is needed. This device employs a secondary pressing method to close the two ends of the perforated mesh, reducing the expansion force. This facilitates subsequent welding and effectively prevents weld detachment by eliminating the expansion force. Utility Model Content

[0004] The purpose of this invention is to provide a filter center tube compression molding device that uses a two-stage compression method to close the two ends of the mesh, reducing the expansion force. This facilitates subsequent welding and effectively prevents subsequent detachment of the weld, thus solving the aforementioned technical problems.

[0010] Preferably, two limiting guide rails are fixedly connected to both ends of the front side of the processing table, and two limiting grooves adapted to the limiting guide rails are opened on the rear side of the sliding seat.

[0011] The beneficial effects of this utility model are:

[0012] 1. This utility model uses the pre-pressing component and the stamping seat to perform the first pressing on the perforated mesh, and then uses the closing plate and the push-pull component to perform the second pressing on the perforated mesh, so that the perforated mesh can be pressed and extruded to form a shape, thereby achieving the purpose of rapid forming and tight closing.

[0013] 2. This utility model uses a push-pull assembly, in which the stepper motor and the threaded rod work together to push the threaded slide block, while the pull rod and the connecting column work together to pull the pressure plate, thereby pressing the two sides of the perforated mesh together and closing the perforated mesh.

[0022] In the following description, embodiments of the filter center tube compression molding device of the present invention will be described with reference to the accompanying drawings.

[0023] Figure 1-4 This invention illustrates a filter center tube compression molding device according to an embodiment of the present invention, comprising a processing table 1: a stamping seat 2 is fixedly connected to the top of the processing table 1, a pre-pressing component 3 is provided on the top of the front side of the processing table 1, the pre-pressing component 3 includes a lifting plate 31, a pressure column 32 is fixedly connected to the front side of the lifting plate 31, a semi-circular groove adapted to the pressure column 32 is provided on the top of the stamping seat 2, an arc-shaped sliding groove 33 adapted to the pressure column 32 is provided on the front side of the processing table 1, and an electric telescopic rod 34 is fixedly installed on the top of the processing table 1. The output end of the telescopic rod 34 is fixedly connected to the top of the lifting plate 31. Both sides of the top of the stamping seat 2 are provided with pressure plates 4. A sliding seat 5 is fixedly connected to the rear side of the surface of the pressure plate 4. Two limiting guide rails 7 are fixedly connected to both ends of the front side of the processing table 1. Two limiting grooves 8 adapted to the limiting guide rails 7 are opened on the rear side of the sliding seat 5. Through the cooperation of the limiting guide rails 7 and the limiting grooves 8, the sliding seat 5 plays a limiting and guiding role, enabling the sliding seat 5 to drive the pressure plate 4 stably along a predetermined trajectory. The sliding mechanism allows the pressing plate 4 to accurately press against the surface of the perforated mesh for extrusion molding. A push-pull assembly 6 is located on the rear side of the processing table 1. The push-pull assembly 6 includes a stepper motor 61 fixedly installed at the bottom of the rear side of the processing table 1. A threaded rod 62 is rotatably connected to the rear side of the processing table 1 via bearings. The bottom end of the threaded rod 62 is fixedly connected to the output shaft of the stepper motor 61. A threaded slide block 63 is threadedly connected to the surface of the threaded rod 62. A connecting post 65 is fixedly connected to the rear side of the slide block 5. Two... Each end of the threaded slide block 63 is provided with a rectangular groove 66 that is adapted to the connecting post 65. Both ends of the threaded slide block 63 are rotatably connected to a pull rod 64. The top end of the pull rod 64 is rotatably connected to the surface of the connecting post 65. Through the setting of the push-pull assembly 6, the stepper motor 61 and the threaded rod 62 work together to push the threaded slide block 63. At the same time, the pull rod 64 and the connecting post 65 work together to pull the closing plate 4, thereby pressing the two sides of the perforated mesh together and closing the perforated mesh.

[0024] Working principle: When using this utility model, the user places the perforated mesh on top of the stamping seat 2. Then, the electric telescopic rod 34 is activated and pushes the lifting plate 31 downward to slide, causing the pressure column 32 to press against the surface of the perforated mesh, pressing the perforated mesh into a semi-circle. Then, the stepper motor 61 is activated and drives the threaded rod 62 to rotate. The threaded rod 62 drives the threaded slide block 63 to slide downward through its surface threads. During the sliding process, the threaded slide block 63, in cooperation with the pull rod 64, pulls the connecting column 65 to slide in the inner cavity of the rectangular slide groove 66, thereby causing the pressing plate 4 to slide downward at an angle. At this time, the pressing plate 4 presses against the surface of the perforated mesh, pressing the perforated mesh into shape. Finally, the stepper motor 61 rotates in the opposite direction. Through the cooperation of the threaded rod 62, the threaded slide block 63 and the pull rod 64, the pressing plate 4 is driven to return to its original position. Finally, the electric telescopic rod 34 and the lifting plate 31 drive the pressure column 32 and the central tube to return to their original position. Finally, the central tube is removed from the surface of the pressure column 32.
