Abstract
Description
Technical Field
[0001] The present invention relates to a bubble elimination device for phosphating a cylindrical workpiece, and relates to a bubble elimination device for assisting in the phosphating of a cylindrical workpiece, belonging to the field of workpiece processing equipment. In particular, the present invention relates to a device equipped with a drive mechanism that can adjust the angle of the workpiece barrel without human intervention, effectively expel tiny bubbles remaining on the inner wall of the barrel during the phosphating reaction, and ensure uniform phosphating. Background Art
[0002] At present, when phosphating a cylindrical part with an open end, it is generally tilted and placed in the barrel with the opening facing upward to prevent bubbles from accumulating in the barrel. Then, after the phosphating is completed, the barrel is taken out with the open end facing downward to pour out the phosphating liquid in the barrel. Traditionally, this action is generally performed manually, which is time-consuming and labor-intensive, and there are safety hazards. In addition, this method of eliminating bubbles in the barrel cannot completely eliminate the bubbles. Tiny bubbles are easily adhered to the inner wall of the barrel, affecting the subsequent phosphating reaction.
[0003] Publication No. CN211645384U discloses a hanger for phosphating cylindrical parts, comprising a support frame, a suspension rope, an upper crossbeam, a lower crossbeam, and a slide assembly. The hanger requires the cylinder inclination to be adjusted back and forth during operation, which is cumbersome to operate. Furthermore, the tiny bubbles retained on the inner wall of the cylinder are difficult to effectively remove.
[0004] Announcement No. CN209443085U discloses a simultaneous phosphating spray hanger for the inside and outside of a cylindrical body with a threaded mouth. The hanger is a cylindrical frame made of steel bars, and the diameter of the steel bars is consistent with the wall thickness of the projectile; the bottom of the hanger is a small circle made of steel bars, and the upper part of the hanger is a large circle made of steel bars. The diameter of the small circle is the same as the diameter of the mouth of the projectile. Three steel bars are used to connect the small circle and the large circle. The steel bars are evenly distributed at 120°. The steel bars are bent into an arc at both ends of the large circle diameter to form a hook. The height of the top of the hook from the large circle should meet the requirements for taking and placing the projectile. The hanger cannot eliminate tiny bubbles inside the cylinder.
