Description

Technical Field

[0001] This utility model relates to the field of metal surface treatment technology, specifically to a sandblasting pipe for a metal fitting sandblasting machine. Background Technology

[0002] During the manufacturing process, metal parts often require surface treatment to remove surface dirt, oxide layers, or to roughen the surface to enhance coating adhesion. Sandblasting is a commonly used surface treatment method that uses high-pressure gas to spray abrasive onto the metal surface to achieve cleaning and pretreatment.

[0003] Referring to the announcement number CN220373030U, a sandblasting pipe for a sandblasting machine includes a fixed base. An L-shaped pipe is connected to the left wall of the fixed base, and a first tensile thread is formed on the outer wall of the bottom of the L-shaped pipe. A receiving seat is fixedly connected to the right wall of the fixed base. This sandblasting pipe can be removed using bolts and nuts. The mounting seat drives a semi-circular locking block and a semi-circular sealing ring to open and disengage from the connecting pipe, causing a semi-circular rubber block to disengage from the annular groove. The semi-circular locking block and the semi-circular sealing ring are then moved to the damaged position of the sandblasting pipe body and fixed with bolts and nuts. The sandblasting pipe body can then be replaced. This allows for emergency sealing and fixing in the event of cracks or breaks in the sandblasting pipe body. Replacement is then performed after sandblasting is completed. The replacement process is simple and easy for workers to operate. While this sandblasting pipe has good applications, its overall design is usually complex and not conducive to dual-channel sandblasting operations, often causing problems for users.

A fourth threaded connector 9 is threadedly installed at the other end of the tee pipe 5. A second sandblasting hose 10 is provided at the end of the fourth threaded connector 9 away from the tee pipe 5. A fifth threaded connector 11 is provided at the end of the second sandblasting hose 10 away from the fourth threaded connector 9.

[0022] In use, the second sandblasting hose 10 and the second valve 12 can be disassembled and assembled through the fifth threaded connector 11.

[0023] The fifth threaded connector 11 is threaded with a second valve 12 at the end away from the second sandblasting hose 10, and the second valve 12 is threaded with a second threaded connector 14 at the end away from the fifth threaded connector 11.

[0024] In use, the second threaded connector 14 is provided to facilitate the disassembly and assembly of the second valve 12 and the flow pipe 15.

[0025] The top end of the second threaded connector 14 is provided with a flow tube 15, and the end of the flow tube 15 away from the second threaded connector 14 is threaded with a seventh threaded connector 16.

[0026] In use, the seventh threaded connector 16 is provided to facilitate the disassembly and assembly of the flow pipe 15 and the second sandblasting connector 17.
