Description

Technical Field

[0001] This utility model relates to the field of stamping die technology, and in particular to a stamping die for the outer shell of a fan coil unit. Background Technology

[0002] Stamping dies are special process equipment used in cold stamping to process materials (metal or non-metal) into parts (or semi-finished products). They are called cold stamping dies (commonly known as cold stamping dies). Stamping is a pressure processing method that uses dies mounted on a press to apply pressure to materials at room temperature, causing them to separate or plastically deform, thereby obtaining the desired parts.

[0003] The production of the outer casing of existing fan coil units requires the use of stamping dies. The structure in the stamping die enables processes such as stretching, bending, and punching to process metal sheets (galvanized steel sheets) into the outer casing components required for fan coil units.

[0004] However, existing stamping dies involve directly placing the raw materials to be processed onto the lower structure of the die and feeding them directly onto it for stamping. During this feeding process, dust or particles may adhere to the surface of the raw materials. These particles can damage the material's strength and affect the processing quality during stamping. To address this issue, a new type of stamping die for the outer casing of a fan coil unit is proposed. Utility Model Content

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Reference Figure 1 , Figure 2 , Figure 4 and Figure 5This utility model provides an embodiment of a stamping die for a fan coil unit housing, including a stamping table 1, which is the main body of the stamping die. The stamping structure is installed on the stamping table 1 to provide stable support for stamping. Two hydraulic rods 3 are fixedly connected to the middle of the stamping table 1. An upper stamping block 10 is fixedly connected to the output end of the two hydraulic rods 3. The two hydraulic rods 3 drive the upper stamping block 10 to move, ensuring the stability of the upper stamping block 10 during the stamping process and providing stable support for the stamping quality. A lower stamping block 11 is fixedly connected inside the stamping table 1. The lower stamping block 11 and the upper stamping block 10 cooperate with each other to perform stamping processing. A limit component and a cleaning component are provided on the front side of the stamping table 1. A collection box 2 is provided on the rear side of the stamping table 1. The stamped products are placed in the collection box 2.

[0035] The cleaning assembly includes two fixed blocks 4, both of which are fixedly connected to the front side of the stamping table 1. The two fixed blocks 4 are symmetrically designed and fixed to the two sides of the front of the stamping table 1 with screws. Each fixed block 4 has a square groove 17 on its inner side, and a slider 22 is slidably connected inside the square groove 17. The square groove 17 supports the slider 22 to move up and down within it, and also allows the slider 22 to be locked inside, preventing it from falling off during movement. An upper roller brush 5 is rotatably connected between the two sliders 22, and a lower roller brush 18 is rotatably connected between the two fixed blocks 4. Both roller brushes can rotate and clean the surface of the raw material during material feeding, removing impurities and dust. A threaded rod 19 is threadedly connected inside the fixed block 4, and a connecting block 21 is fixedly connected to the bottom of the threaded rod 19. The threaded rod 19 can move within the fixed block 4. The threaded rod 19 is positioned to move the connecting block 21, which in turn restricts the movement range of the threaded rod 19. The connecting block 21 is rotatably connected to the top of the slider 22. The threaded rod 19 drives the connecting block 21 to rotate on the top of the slider 22, adjusting the position of the slider 22. A circular block 23 is rotatably connected inside the slider 22 and is fixedly connected to the bottom of the connecting block 21. The connecting block 21 drives the slider 22 to move inside the square groove 17 through the circular block 23 at the bottom, achieving height adjustment. A knob 20 is fixedly connected to the top of the threaded rod 19, located on the top of the fixed block 4. The threaded rod 19 can be easily rotated from the outside through the knob 20, thereby moving the slider 22 and adjusting the height of the upper roller brush 5. By setting the cleaning component, dust on the surface of the raw material can be cleaned. At the same time, the position of the upper roller brush 5 can be adjusted to adapt to raw materials of different thicknesses, improving the quality of stamped products.

[0036] Reference Figures 1-3The limiting assembly includes a bidirectional screw 14, which is rotatably connected to the inside of the stamping table 1. This rotatable connection allows the bidirectional screw 14 to rotate within the stamping table 1. A through slot 6 is provided inside the stamping table 1, and a round rod 7 is fixedly connected inside the slot 6. The bidirectional screw 14 is located below the through slot 6. Two movable rods 8 are threadedly connected to the outside of the bidirectional screw 14. When the bidirectional screw 14 rotates, it drives the two movable rods 8 to move in opposite directions via the round rod 7. Both movable rods 8 are slidably connected to the outside of the round rod 7, and the moving rods 8 are limited in their direction and range of movement by the round rod 7. A limiting plate 12 is fixedly connected to the top of each movable rod 8, and the position of the limiting plate 12 is adjusted when the movable rod 8 moves. A motor 9 is fixedly connected to the outside of the stamping table 1, and the bidirectional screw 14 is fixedly connected to the output end of the motor 9. The motor 9 drives the bidirectional screw... The rod 14 rotates, thereby adjusting the position of the moving rod 8 and changing the range of the limiting plate 12. A circular hole 15 is provided in the middle of the moving rod 8, and the circular rod 7 is located inside the circular hole 15. The moving rod 8 moves outside the circular rod 7 through the internal circular hole 15. A threaded hole 16 is provided inside the moving rod 8, and a bidirectional screw 14 is threaded into the threaded hole 16. The bidirectional screw 14 drives the moving rod 8 to slide on the circular rod 7 through the threaded hole 16. Multiple rollers 13 are rotatably connected to the inner side of the limiting plate 12. The rollers 13 rotate when the raw material is conveyed, which can prevent the raw material to be stamped from being scratched during the movement, and at the same time ensure the smooth movement of the raw material. By setting the limiting component, the position of the limiting plate 12 is precisely adjusted by the bidirectional screw 14 and the motor 9 to ensure accurate positioning of the stamping sheet and improve the precision and quality of the stamping product.

[0037] Working principle: First, the raw material to be stamped is placed between two limiting plates 12. Then, the motor 9 is started, and the motor 9 drives the bidirectional screw 14 to rotate. The bidirectional screw 14 drives the external moving rod 8 to move horizontally under the restriction of the round rod 7, thereby adjusting the distance between the two limiting plates 12. Adjusting the limiting plates 12 to a suitable size can restrict the raw material to be processed, preventing it from moving and affecting the stamping process. At the same time, multiple rollers 13 set on the inner surface of the limiting plates 12 rotate with the raw material during the material conveying process, without damaging the surface of the steel.

[0038] Next, after the raw material passes between the two limiting plates 12, it passes through the two roller brushes. The upper roller brush 5 and the lower roller brush 18 are used to clean the raw material to be stamped. When the material thickness is different, the knob 20 on the top of the two fixed blocks 4 is turned. The knob 20 drives the threaded rod 19 to rotate inside the fixed block 4. The connecting block 21 at the bottom of the threaded rod 19 rotates inside the slider 22 through the circular block 23. As a result, the threaded rod 19 rises and drives the two sliders 22 to move in the square groove 17. The distance between the upper roller brush 5 and the lower roller brush 18 is adjusted to deal with materials of different thicknesses.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
