Description

Technical Field

[0001] This utility model relates to the technical field of metal sandblasting devices, and specifically to a sandblasting device for metal surface treatment. Background Technology

[0002] In the field of metal processing, sandblasting is a key process for improving the surface properties and appearance of metals. It uses high-speed jet abrasive to impact and grind the metal surface, achieving functions such as rust removal, oxide scale removal, and increasing surface roughness to improve the adhesion of subsequent coatings. It is widely used in industries such as machinery manufacturing, automotive parts processing, and hardware production.

[0003] Currently available metal surface treatment sandblasting equipment faces several pressing issues. In terms of workpiece positioning and transmission, traditional devices often employ a single fixed method or a simple rotating mechanism, making it difficult to achieve stable workpiece clamping and multi-dimensional uniform force distribution. This leads to workpiece displacement during sandblasting and inconsistent sandblasting depth. Especially for workpieces requiring omnidirectional treatment, frequent manual adjustments to the workpiece position are often necessary, increasing operational complexity and reducing processing efficiency and finished product yield. While some devices incorporate positioning structures, the poor coordination between the positioning and power components prevents precise alignment between the workpiece and the nozzle according to sandblasting requirements.

[0023] Example: A sandblasting apparatus for metal surface treatment, as shown in the attached document. Figure 1 - Appendix Figure 4The system includes a processing table 1, with a screen 11 fixed to its top. A positioning component 4 and a power component 5 are located on one side of the top of the screen 11. The positioning component 4 includes two sets of mounting brackets 41 fixed to the top of the processing table 1, a rotating wheel 42 mounted on the top of the mounting brackets 41, a turntable 44 mounted on the top of the mounting brackets 41, and a fixed column 45 mounted on the turntable 44. The power component 5 includes a drive motor 51, two sets of uprights 53 fixed to the top of the processing table 1, and rotating rods 54 sleeved on the upper and lower sets of uprights 53. One side of each rotating rod 54 is fixed to a transition plate 52. The adapter plates 52 are connected by connecting rods 55. The other end of the top adapter plate 52 is connected to the eccentric disk by a rod structure. The middle part of the eccentric disk is connected to the output end of the drive motor 51. The middle part of each set of rotating rods 54 is fixed with a nozzle 75 by a pipe clamp. The outer side of the positioning component 4 and the power component 5 is covered with a cover plate 2. The outer side of the cover plate 2 is fixed with an air intake component 7. The air intake component 7 includes a manifold 71, a side pipe 72 and a main pipe 73 connected to the manifold 71. The main pipe 73 is connected to the spray gun 74, and the side pipe 72 is connected to the nozzle 75.

[0024] The rotating wheels 42 are connected by a belt 43 for transmission. The middle of the turntable 44 is fixedly connected to the rotating column 46. The bottom of the rotating column 46 is connected to the middle of the rotating wheel 42. The top of the rotating column 46 is connected to the output end of the main servo motor 48 for transmission. The top of one side rotating wheel 42 is connected to the output end of the side servo motor 47 for transmission. The two sets of servo motor structures rotate synchronously. In the air intake assembly 7, the manifold 71 is connected to the nozzle 75 through the side pipe 72 and to the spray gun 74 through the main pipe 73, realizing the precise distribution of a single main air source to multiple nozzles 75 and spray guns 74, ensuring the stability of airflow pressure during sandblasting and improving the sandblasting effect. The manifold 71 is fixed to the outside of the cover plate 2 by a plate structure. The pipeline connection structure is simple, which is convenient for installation, inspection and maintenance, and reduces the use and maintenance costs of the equipment. In addition, the entire device has a compact structural layout, smooth cooperation of each component, and convenient operation, which can effectively improve production efficiency.

[0025] A square groove is provided at the top of the cover plate 2, and a recovery hood 6 is fixed at the top of the square groove. One end of the recovery hood 6 is connected to the recovery chamber 62 through a smoke pipe 61. One end of the recovery chamber 62 is connected to one end of the blower 3, and the other end of the blower 3 is connected to the bottom end of the screen 11. The device covers the positioning component 4 and the power component 5 through the cover plate 2, realizing a sealed environment for sandblasting operations and reducing dust leakage. The square groove at the top of the cover plate 2 fixes the recovery hood 6, which is connected to the recovery chamber 62 through the smoke pipe 61. The recovery chamber 62 forms a circulation path with the blower 3 and the bottom end of the screen 11. When the blower 3 is working, it can draw abrasive, impurities and dust generated during sandblasting into the recovery chamber 62 through the recovery hood 6. After screening, qualified abrasive can be reused in sandblasting operations through the screen 11, realizing efficient recycling of abrasive and reducing resource waste. At the same time, the combination of the sealed structure and the recovery system effectively controls dust diffusion, improves the working environment, and protects the health of operators.

[0026] One end of the manifold 71 is connected to the main pipe, and the other end of the manifold 71 is fixed to the outside of the cover plate 2. This device achieves coordinated movement of the workpiece and the nozzle 75 by setting up an optimized positioning component 4 and a power component 5. In the positioning component 4, two sets of rotating wheels 42 are connected by a belt 43. The turntable 44 is connected to the rotating wheels 42, the main servo motor 48, and the side servo motor 47 via a rotating column 46. The two sets of servo motors rotate synchronously, which can drive the workpiece to achieve stable rotation and angle adjustment, ensuring that all surfaces of the workpiece can be sandblasted evenly. In the power component 5, the drive motor 51 drives the eccentric disk to rotate, and drives two sets of rotating rods 54 to move up and down along the column 53 through the adapter plate 52 and the connecting rod 55. This causes the nozzle 75 fixed on the rotating rod 54 to move up and down reciprocally. Combined with the rotation of the workpiece, the sandblasting dead angle is completely eliminated. Meanwhile, the multiple sets of fixed posts 45 arranged equidistantly on the outer edge of the turntable 44 in the positioning component 4, combined with the rotating wheel 42 at the bottom of the fixed posts 45, can stably clamp and position workpieces of different sizes, thus improving the applicability of the device.

[0027] Each set of fixed columns 45 has a rotating wheel 42 fixed at its bottom end, and multiple sets are arranged in an equidistant array on the outer edge of the turntable 44.

[0028] The nozzles 75 on the two sets of rotating rods 54 are symmetrically oriented vertically. Driven by the power component 5, the nozzles 75 on the two sets of rotating rods 54 are symmetrically arranged vertically. While reciprocating up and down, the symmetrical nozzles 75 can sandblast the workpiece from different angles, significantly expanding the sandblasting coverage. The nozzles 75 are fixed to the middle of the rotating rods 54 by pipe clamps, facilitating adjustment of the nozzle angle and spacing according to workpiece processing requirements, thus achieving precise control of sandblasting parameters. This multi-dimensional, adjustable sandblasting structure design effectively improves the uniformity and quality of sandblasting on the surface of metal workpieces, reducing the defect rate.
