Description

Technical Field

[0001] The utility model relates to a sandblasting device, in particular to a rotary blade sandblasting tooling. Background Art

[0002] In traditional automatic sandblasting machine applications, for blades of different sizes, shapes and surface treatment requirements, it is usually necessary to adjust the sandblasting machine's process parameters, such as sandblasting pressure, sandblasting angle and sandblasting time, to achieve the ideal surface passivation effect. However, this method has several significant problems:

[0003] Low production efficiency: Each adjustment of process parameters requires stopping the machine, resetting and verifying the effect, which greatly extends the production cycle and reduces overall production efficiency.

[0004] Difficulty in quality control: Different batches of products may have inconsistent surface quality due to slight differences in process parameters, which increases the difficulty of quality control.

[0005] Low equipment utilization: When processing a variety of products, traditional sandblasting machines cannot fully utilize their sandblasting capacity and space, resulting in a waste of equipment resources.

[0006] High cost: For products that require different passivation values, if sandblasting is performed separately, the equipment, manpower and time costs will be significantly increased.

[0007] Therefore, the market urgently needs a blade sandblasting tooling that can simultaneously meet the requirements of different sandblasting process parameters to improve production efficiency, ensure product quality and reduce production costs. Utility Model Content

[0008] The utility model aims to provide a rotary blade sandblasting tool to improve production efficiency.

[0009] The utility model is realized by adopting the following technical scheme: a rotary blade sandblasting tool, characterized in that it includes a hanger, a nozzle, and a blade mounting rod, wherein the hanger is installed on a rotating shaft, the blade mounting rod is arranged on the hanger, a plurality of blade mounting rods are provided, and multiple layers are arranged on the hanger, the multiple layers of blade mounting rods are all rotatably connected to the hanger, and the nozzle is arranged on one side of the hanger.

[0010] Furthermore, the hanger includes a top cover and a base, a support column is provided between the top cover and the base, and the support column is coaxial with the rotating shaft.

[0011] Furthermore, both ends of the blade mounting rod are rotatably connected to the top cover and the base respectively, and the blade mounting rods are arranged along the circumference on the hanger and are provided with two layers.

[0012] Furthermore, a gear is provided at the bottom of the blade mounting rod, and the gears on the blade mounting rods of two adjacent layers are meshed with each other.

[0013] Furthermore, a paddle is provided on the outside of the hanger. When the blade mounting rod moves to the paddle, the outer gear is moved by the paddle and rotates, and at the same time drives the inner gear to rotate.

[0014] Furthermore, a plurality of blades are provided on the blade mounting rod, and each blade is provided with spacer beads at both upper and lower ends.

[0015] Furthermore, in the multi-layer blade mounting rod, the blades arranged on the outer blade mounting rod have the largest passivation value, and the passivation value of the blades decreases from the outer to the inner, ensuring that the outer side is fully sandblasted and the blades are not damaged.

[0016] The rotary blade sandblasting tooling described in the utility model has the following beneficial effects:

[0017] Improved production efficiency: By designing a rotary blade sandblasting tool, multiple blades with different passivation requirements can be sandblasted simultaneously. This parallel processing significantly reduces the time required to change blades or adjust process parameters, thereby improving overall production efficiency.

[0018] Ensure uniform sandblasting: The blade mounting rods are arranged along the circumference of the bracket and rotate synchronously through gear transmission. This design ensures that each blade is evenly impacted by the sandblasting fluid during the sandblasting process, thus achieving uniform surface passivation.

[0019] Protecting sharp blades: Placing blades with greater bluntness on the outside of the tooling reduces fluid pressure on the inner blades by blocking the outer blades. This layout not only ensures adequate sandblasting of the outer blades but also effectively prevents damage to the inner blades due to excessive pressure, thereby improving product quality.

[0020] Enhanced equipment adaptability: The design of this tooling enables the automatic sandblasting machine to more flexibly adapt to sandblasting treatments with different blade types and passivation value requirements, thereby improving the versatility and adaptability of the equipment.

[0021] Reduced production costs: The ability to process multiple blades simultaneously reduces equipment downtime and labor input, thereby reducing production costs. In addition, the tooling's rational structural design makes it easy to operate and maintain, further reducing operating costs.

[0022] Optimize space utilization: Through reasonable layout and structural design, the internal space of the sandblasting machine is fully utilized, which improves space utilization and sandblasting efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0028] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but rather merely represents selected embodiments of the present invention. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort are also within the scope of protection of the present invention.

[0029] like Figure 1-2 As shown, a rotary blade sandblasting tool includes a hanger 1, a nozzle 2, and a blade mounting rod 3. The hanger 1 is mounted on a rotating shaft and includes a top cover and a base. A support column is provided between the top cover and the base, and the support column is coaxial with the rotating shaft. The ends of the blade mounting rod 3 are respectively connected to the top cover and the base, and the nozzle 2 is provided on one side of the hanger 1.

[0030] The blade mounting rods 3 are arranged along the circumference of the hanger 1 and are provided in at least two layers. Gears 4 are provided at the bottom of the blade mounting rods 3. The gears 4 on the blade mounting rods 3 of two adjacent layers mesh with each other. A paddle 5 is provided on the outside of the hanger 1. When the blade mounting rods 3 move to the paddle 5, the outer gears 4 are moved by the paddle 5 and rotated, simultaneously driving the inner gears 4 to rotate, so that each surface is evenly sprayed.

[0031] The blade mounting rod 3 is provided with a plurality of blades 7 , and spacer beads 6 are provided between the blades 7 , and it is ensured that each blade 7 is provided with a spacer bead 6 at both upper and lower ends.

[0032] Because these blades require different levels of edge blunting, those with higher blunting values can withstand higher fluid pressures, exceeding the blasting pressure required for sharp blades. This tool places the more blunt blades on the outside of the tool. Because of the obstruction caused by the outer blades, the inner edge experiences lower fluid pressure than the outer edge. Simultaneously blunting both blades ensures thorough sandblasting on the outer edge while preserving damage to the inner edge.

[0033] The above embodiments describe the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Without departing from the spirit and scope of the present invention, modifications and variations made by those skilled in the art without departing from the spirit and scope of the present invention should be within the scope of protection of the appended claims.
