Description

Technical Field

[0001] The utility model relates to the technical field of sandblasting rust removal devices, in particular to a sandblasting rust removal device for valve production and processing. Background Art

[0002] Sandblasting is a specialized device used to remove rust, oxidation, and stains from surfaces. It uses high-pressure gas or water to accelerate specially prepared sand or other granular media, then sprays it onto the surface to remove rust, clean, or otherwise treat the surface. Sandblasting is widely used in a variety of metal products, building materials, ships, bridges, pipelines, and automobiles.

[0003] At present, during the production and processing of valves, sandblasting and rust removal equipment are needed for rust removal operations.

[0004] The prior art publication number CN217317596U is a sandblasting device for raw material surface for metal valve processing, which includes a working box, a bracket, a sandblasting mechanism, a cylinder, a left splint, a right splint, a rotating shaft and a motor. A working chamber is provided in the working box, the left end of the cylinder is connected to the center position of the left end of the working chamber, and the right end of the cylinder is rotatably connected to the left end of the left splint.

[0005] The device can evenly sandblast the valve body to ensure the rust removal effect, but there are still some defects in the actual use of the device. During the rust removal of the valve workpiece, two manual clamping operations are required (after the first sandblasting and rust removal, it needs to be manually removed and the angle changed and re-clamped). The sandblasting and rust removal operation cannot be completed with one manual clamping, which undoubtedly reduces the rust removal efficiency of the valve workpiece. For this reason, improvements are proposed. Utility Model Content

[0011] Furthermore, the rotating assembly includes a mounting base, and the mounting base is fixedly mounted on the inner top of the working box, a motor is fixedly mounted on the inner top of the mounting base, a driving end of the motor is fixedly connected to a driving gear, one side of the outer surface of the driving gear is meshed with a driven gear, the bottom of the driven gear is fixedly connected to a mounting platform, and the mounting platform passes through the mounting base and is fixedly connected to the frame, which can drive the mounting platform to rotate, thereby driving the frame to rotate.

[0012] Furthermore, the mounting platform and the mounting seat are rotatably connected, and the mounting seat supports the mounting platform, which is beneficial to the installation of the mounting platform.

[0013] Furthermore, the sandblasting head assembly includes a crossbar, and the crossbar is fixedly installed at the bottom of the frame. A plurality of nozzles are fixedly connected to the bottom of the crossbar, which is conducive to sandblasting the workpiece.

[0014] Furthermore, adjacent sides of the outer surfaces of the two fork rods are fixedly connected with sliding rods, and the sliding rods pass through the frame and are slidably connected thereto.
