Description

Technical Field

[0001] This utility model relates to the field of laser additive manufacturing technology, specifically to an ultrasonic vibration cleaning device for raw materials adhering to laser additive products. Background Technology

[0002] Laser additive manufacturing technology is a technique based on the principle of discrete stacking, which manufactures parts by adding materials layer by layer. It integrates multiple technologies such as mechanical engineering, CAD, reverse engineering, layered manufacturing, CNC technology, materials science, electron beam and laser technology. It can automatically, directly, quickly and accurately transform design ideas into prototypes or parts with specific functions, such as current laser 3D printing technology. This technology usually uses a laser as an energy source, and melts and stacks powdered materials layer by layer to form a three-dimensional solid. This technology is widely used in aerospace, automotive manufacturing, medical, construction and other fields. It can manufacture parts with complex structures and achieve high-precision and high-efficiency production. However, the powdered material attached to the surface of the formed product needs to be cleaned afterward. At present, the powder can be removed manually by blowing with a fan and tapping and vibrating. However, this method is not clean and thorough, and it is easy to leave powder residues and is not conducive to the recycling and reuse of powder raw materials. Utility Model Content

[0003] To address the aforementioned problems, the purpose of this invention is to provide an ultrasonic vibration cleaning device for raw materials adhering to laser additive products.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows: an ultrasonic vibration cleaning device for raw materials adhering to laser additive products, comprising an inner box and an ultrasonic generator. The top opening of the inner box is covered by a top cover. The bottom of the inner box is elastically supported by an elastic structure with a bottom vibration plate. Gaps are left between the four perimeters of the bottom vibration plate and the inner sidewall of the inner box. Several ultrasonic transducers are fixed on the lower surface of the bottom vibration plate. Each ultrasonic transducer is electrically connected to the output interface of the ultrasonic generator through a wire. The internal space of the inner box above the bottom vibration plate is filled with several steel wool balls, and the steel wool balls have a porous structure.

[0005] Furthermore, the elastic structure is a rubber sleeve, the bottom of which is fixed inside a fixed cylinder on the bottom side wall of the inner box.

[0006] Furthermore, an integrally vulcanized spring is provided on the inner wall of the rubber sleeve.

[0007] Furthermore, a material leakage hole is provided on one side of the bottom of the inner box, and a receiving box communicating with the material leakage hole is provided at the bottom of the inner box.

[0008] Furthermore, the inner box is wrapped with an outer box, and the rear side of the outer box has an opening for pulling out the receiving box.

[0009] Furthermore, the bottom of the outer casing is supported by outriggers.

[0010] Furthermore, the receiving box is slidably supported inside the bottom of the outer casing via a sliding rail structure.

[0011] In use, the laser additive product is placed inside the inner box, and steel wool is filled at the bottom and around the edges. The ultrasonic generator activates the ultrasonic transducer, causing the bottom vibrating plate to vibrate rapidly. Simultaneously, the force is transmitted to the laser additive product through each steel wool, ultimately causing the product to vibrate and dislodge the powder material from its surface. Because the steel wool itself has a porous structure, the dislodged powder material falls through the steel wool onto the bottom vibrating plate, then through the discharge hole at the bottom of the inner box into a connected receiving box for effective collection. Furthermore, the contact between the vibrating steel wool and the surface of the laser additive product generates friction, achieving a polishing effect and thoroughly cleaning away any residual powder material that is difficult to remove, resulting in a better surface treatment effect.

[0016] The following is a detailed description of this embodiment with reference to the accompanying drawings:

[0017] This embodiment provides an ultrasonic vibration cleaning device for adhering raw materials to laser additive products. Please refer to the accompanying drawings in the instruction manual. Figure 1-2 .

[0018] like Figure 1-2 As shown, an ultrasonic vibration cleaning device for adhering raw materials in laser additive products includes an inner box 1 and an ultrasonic generator 2, such as the ultrasonic generator 2 currently available on the market. The top opening of the inner box 1 is covered by a top cover 3. The bottom of the inner box 1 is elastically supported by a bottom vibration plate 4 through an elastic structure. The four edges of the bottom vibration plate 4 have gaps with the inner sidewall of the inner box 1. Several ultrasonic transducers 5 are fixed on the lower surface of the bottom vibration plate 4. Each ultrasonic transducer 5 is electrically connected to the output interface of the ultrasonic generator 2 through a wire. The internal space of the inner box 1 above the bottom vibration plate 4 is filled with several steel wool balls 6, and the steel wool balls 6 have a porous structure.

[0019] The elastic structure is a rubber sleeve 7. The bottom of the rubber sleeve 7 is fixed inside the fixing cylinder 8 on the bottom side wall of the inner box 1. An integrally vulcanized spring is provided on the inner side wall of the rubber sleeve 7. A material leakage hole 9 is provided on one side of the bottom of the inner box 1. A material receiving box 10 communicating with the material leakage hole 9 is provided below the bottom of the inner box 1.

[0020] The inner box 1 is wrapped with an outer box 11. The rear side of the outer box 11 is provided with an opening for pulling out the receiving box 10. The bottom of the outer box 11 is supported by a support leg 12. The receiving box 10 is slidably supported in the bottom of the outer box 11 by a slide rail structure 13.

[0021] The working principle of this utility model is as follows: For ease of operation, the control panel can be placed on the outer side of the outer casing 11. The laser additive product is placed inside the inner casing 1, and steel wool balls 6 are filled at the bottom and around the perimeter. The ultrasonic generator 2 activates the ultrasonic transducer 5, thereby driving the bottom vibrating plate 4 to vibrate rapidly. At the same time, the force is transmitted to the laser additive product through each steel wool ball 6, ultimately causing the laser additive product to vibrate and causing the powder material on its surface to fall off through the vibration. Since the steel wool ball 6 itself has a porous structure, the material powder that falls off through the vibration can fall onto the bottom vibrating plate 4 through the steel wool ball 6, and then enter the connected receiving box 10 through the bottom of the inner casing 1, the material leakage hole 9, and is effectively collected through the receiving box 10. In addition, when the vibrating steel wool ball 6 comes into contact with the surface of the laser additive product, it will also produce a certain friction effect, thereby achieving the effect of friction polishing the surface of the laser additive product. Moreover, it can thoroughly clean the residual material powder that is difficult to clean from the surface, resulting in a better surface treatment effect for the product.

[0022] Of course, the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it; although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
