Description

Technical Field

[0001] This utility model relates to the field of surface treatment technology, specifically to a fastener anti-corrosion treatment device. Background Technology

[0002] Fastener corrosion protection treatment involves forming a protective layer on the surface to isolate corrosive media. It is mainly divided into four categories: metal coatings: zinc plating (electroplated zinc, hot-dip galvanized, mechanical zinc plating), zinc-nickel alloy, chromium plating, etc.; chemical conversion coatings: phosphating, blackening / bluing, passivation; coating technologies: PTFE coating, wax sealing, chromium-free coating; composite treatment: coating + passivation + sealing agent combination.

[0003] Phosphating of fasteners is a process that forms a phosphate protective film on the metal surface through a chemical reaction. Its main functions are corrosion prevention, enhanced coating adhesion, and lubrication. Existing phosphating equipment typically places fasteners in a drum, rotating it to fully immerse them in the phosphating solution. However, when the fasteners are removed from the phosphating tank, the drum easily carries some of the phosphating solution into the next treatment tank, causing dilution and waste. Utility Model Content

[0004] To address the above deficiencies, this utility model provides a fastener anti-corrosion treatment device to solve the problem of fastener phosphating treatment.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A fastener corrosion protection device, comprising: Phosphating tank; The frame is slidably mounted above the phosphating tank via an electrically guided slide rail at its bottom. The hoisting frame is installed at the bottom of the machine frame using a winch. The support frame is suspended from the hoisting frame at both ends; Drive unit one is installed on one side of the phosphating tank; A rotating shaft is movably inserted into a support frame, and a drive device can be used to drive the rotating shaft to rotate. The driving gears, in a set, are mounted at both ends of the rotating shaft; The rotating drum is movably mounted at both ends on the bottom of the support frame via a set of rotating shafts. The external gear rings, as a set, are installed at both ends of the rotating drum and mesh with a set of driving gears; Drive device two is installed on one side of the hoisting frame and can be used to drive the rotating shaft to rotate; The electric actuator is installed on top of the hoisting frame; The connecting plate is installed on the telescopic end of the electric actuator; The jetting pipes consist of several sets, installed at an angle on both sides of the bottom of the connecting plate.

[0006] Furthermore, a set of hanging plates is installed on both sides of the bottom of the hoisting frame, and a horizontal plate corresponding to the set of hanging plates is installed on the upper end of the support frame, which facilitates the hoisting frame to hoist the support frame.

[0007] Furthermore, several sets of blowing pipes are connected to an external air pump, which can be installed on a hoisting frame and move with the hoisting frame. Several stainless steel nozzles are evenly installed on the several sets of blowing pipes to facilitate the atomization and blowing away of the phosphating liquid on the surface of the rotating drum.

[0008] Furthermore, a drive gear is installed on the rotating end of the first drive device, a drive gear is installed on the rotating end of the second drive device, and a corresponding transmission gear is installed on the left end of the rotating shaft, so as to facilitate the transmission between the first drive device or the second drive device and the rotating shaft 8.

[0009] Furthermore, the rotating drum has several circular holes evenly spaced on its surface to facilitate the immersion of phosphating solution into the drum, and a sealing cap is hinged at the top to facilitate feeding or unloading.

[0010] Furthermore, a set of support seats are installed on both sides of the upper end of the phosphating tank, and a set of corresponding round rods are installed on both sides of the support frame, so as to facilitate the placement of the support frame on the phosphating tank for phosphating treatment.

[0011] This utility model provides a fastener anti-corrosion treatment device with the following beneficial effects: when the rotating drum is taken out of the phosphating tank, the electric actuator drives several sets of spray pipes to descend, atomizing and blowing away the phosphating liquid on the surface of the rotating drum. In conjunction with the second drive device, the rotating drum is driven to rotate. Under the action of centrifugal force, the rotating drum carries some of the phosphating liquid out and flows back into the phosphating tank, reducing the dilution and waste of the phosphating liquid.
