Description

Technical Field

[0001] The utility model relates to the technical field of surface treatment equipment, in particular to environmentally friendly metal zincizing surface treatment equipment. Background Art

[0002] Sherardizing is mainly used to improve the corrosion resistance of steel materials in the atmosphere and natural water environment. Galvanizing has good corrosion resistance in various atmospheric environments and is widely used outdoors. It is widely used for surface protection of outdoor steel structures and mechanical parts. Before galvanizing, steel materials need to use metal surface treatment equipment to remove rust on their surfaces to ensure better galvanizing effect.

[0003] As disclosed in the utility model with authorization announcement number CN216463891U, a high-efficiency and environmentally friendly metal zinc-diffusion surface treatment equipment is provided, including a workbench, supporting legs, mounting openings, abrasive boxes, side panels, slide grooves, mounting plates, a first motor, screws, screw holes, a second motor, a yoke, mounting holes, a rotating shaft, a gear and a workpiece fixing mechanism, wherein a plurality of evenly distributed supporting legs are fixedly provided at the bottom of the workbench, a mounting opening longitudinally penetrating the workbench is provided at the upper part of the workbench, an abrasive box is fixedly provided on the inner side of the mounting opening, a vertically arranged side panel is fixedly provided on the side of the workbench, a longitudinally arranged slide groove is provided on the side of the side panel, a horizontally arranged mounting plate is slidably provided on the inner side of the slide groove, a first motor with an output shaft vertically arranged downward is fixedly provided on the inner side of the upper end of the slide groove, and when the device is used, the pipe fitting is placed vertically to allow the rotating shaft to be inserted into the upper The inner side of the end, and then the nut is rotated. The nut is screwed downward on the outer side of the external threaded sleeve to drive the extrusion sleeve to move downward. The lower end of the extrusion sleeve will squeeze the side of the push block, so that the free end of the push block gradually moves away from the side of the rotating shaft, and finally the connecting block abuts against the inner wall of the pipe fitting, so that the pipe fitting is fixed, and then the first motor is started to drive the screw to rotate. The threaded connection between the screw and the screw hole is transformed into a mounting plate that slides downward in the slide groove, so that the pipe fitting is completely inserted into the abrasive in the abrasive box. Then the first motor is turned off and the second motor is started. The second motor drives the rotating shaft connected thereto to rotate. Due to the meshing connection of adjacent gears, all the rotating shafts are rotated, so that the pipe fitting rubs against the abrasive in the abrasive box, and the abrasive polishes and removes rust on the inner and outer surfaces of the pipe fitting. There will be a grinding dead angle in the contact part with the pipe fitting on the device, and the installation of the pipe fitting is difficult, and the scope of application is small.
