Description

Technical Field

[0001] This invention is a metal processing surface treatment device, belonging to the technical field of metal processing equipment. Background Technology

[0002] In the processing and production of metal pipe fittings, surface grinding and cleaning are key steps to improve the surface precision of the workpiece and remove oxide scale and burrs. Traditional surface treatment of metal pipe fittings often involves manual grinding combined with external rinsing, which suffers from problems such as asynchronous internal and external surface treatment, low grinding precision, incomplete cleaning, and easy splashing of waste chips and waste liquids, polluting the environment. Existing automated processing equipment generally can only achieve single external surface treatment, and cannot simultaneously handle the grinding and cleaning of the inner wall of the pipe fitting. Furthermore, it suffers from poor clamping and positioning stability and low waste chip collection efficiency, making it difficult to meet the batch surface treatment requirements of high-precision metal pipe fittings. Therefore, there is an urgent need for a metal processing surface treatment device that can achieve simultaneous internal and external cleaning and precise clamping and positioning of the pipe fitting during the internal wall grinding process.

Nozzle 1014 surrounds the outer wall of pipe for high-pressure flushing, and internal and external cleaning are completed simultaneously.

[0030] Grinding waste and cleaning waste liquid fall into the lower cavity of the tube seat 14 under the action of gravity, and flow into the collection box 5 through the outlet 15 and the guide pipe, so as to achieve closed collection, no splashing and no pollution.

[0031] The water tank 6 has several water inlets 17 on both sides of its top. The side of the arc-shaped fixing plate 1002 away from the guide ring 1001 has several expansion joints 18. The corresponding sides of the arc-shaped fixing plate 1003 have several expansion joints 29 and 3. The upper hose 1015 passes through the expansion joints 18, 29 and the corresponding water inlets 17 and connects to the water pump in the water tank 6. The lower hose 1015 passes through the expansion joint 3 and the water inlet 17 on the other side. The water tank 6 is connected to a water pump.

A hose 1015 is wound around the rotating cylinder 22.

[0032] When the external cleaning component moves, it pulls on the hose 1015. The rotating drum 22 automatically rotates under the elastic force of the spring 24 to release or retract the hose, keeping the hose taut and preventing tangling, pulling, and wear.

[0033] In this embodiment, motor one, motor two, cylinder one, cylinder two, and the water pump in the water tank are all connected to an external power supply and control system to achieve automated control.

[0034] In use, the metal pipe workpiece is placed in the upper cavity of the pipe body seat, and the cylinder 416 of the pneumatic auxiliary unit 402 is activated. The air rod 417 pushes the fixing block 403 to rise. The fixing block 403 drives the limiting rod 404 to move upward, and the driving arm 405 rotates along the shaft 411. Through the limiting rod 407, the clamping slider 408 slides towards each other along the track 409. The L-shaped clamping block 412 clamps the outer wall of the pipe at the same time, so as to achieve stable positioning of the workpiece.

[0035] When the motor 801 of the grinding assembly 8 is started, the output shaft drives the lead screw 805 to rotate. The internal threaded sleeve 816 moves up and down along the lead screw 805. Through the pull rod 814 and the side plate 809, the column 812 and the grinding head 813 swing. The cylinder 803 drives the air rod 804 to extend and retract, adjusting the height of the grinding head 813 so that the grinding head 813 extends into the inner wall of the pipe for rotational grinding. At the same time, the motor 801 drives the whole assembly to rotate, realizing all-round grinding of the inner wall of the pipe.

[0036] The internal cleaning component 9 introduces the cleaning fluid from the water tank 6 into the conduit 908, pipe adapter 906, and bend 907 via the hose 909. It rotates synchronously with the screw 805 to simultaneously flush the inner wall of the pipe. The external cleaning component 10's motor 1004 drives the output shaft 2 to rotate, which in turn drives the pipe connection component 1010 to move circumferentially along the guide ring 1001 via the drive arm 1019. The nozzle 1014 performs annular flushing on the outer wall of the pipe, and the internal and external cleaning are carried out simultaneously.

[0037] The waste chips and cleaning waste liquid generated during grinding fall into the lower cavity of the pipe seat 14, and are collected in the collection box 5 through the outlet 15 and the pipeline to avoid pollution; the rotating cylinder 22, together with the spring 24, realizes the automatic extension and retraction of the hose 1015, ensuring smooth pipeline operation.
