Description

Technical Field

[0001] The utility model relates to the technical field of wire phosphating, in particular to a continuous phosphating device for high-carbon chromium bearing steel wire. Background Technique

[0002] High-carbon chromium bearing steel wire is a high-performance material used for manufacturing bearings. Its main components include high contents of carbon and chromium, and it is usually used in the production of rolling bearings and sliding bearings, with good hardness, wear resistance and fatigue resistance. The continuous phosphating device for high-carbon chromium bearing steel wire is a device used for treating the surface of high-carbon chromium bearing steel wire. Phosphating treatment is a surface anti-corrosion process, and its main purpose is to improve its anti-corrosion performance and lubrication performance by forming a phosphate layer on the metal surface, which is applicable to the post-treatment of mechanical parts.

[0003] The existing continuous phosphating devices for high-carbon chromium bearing steel wire are mostly composed of a phosphating tank, a bracket and guide wheels for guiding the wire direction. When the wire surface is cleaned, it is immersed in the phosphating solution inside the phosphating tank by the guiding action of the guide wheels for phosphating treatment. During phosphating, the phosphating solution in the phosphating tank is heated by an electric heating belt embedded in the phosphating tank. Since the electric heating belt is arranged outside the whole phosphating solution, it is easy to cause uneven heating inside the phosphating solution, thereby affecting the phosphating effect on the wire. For this reason, we propose a continuous phosphating device for high-carbon chromium bearing steel wire. Content of the Utility Model

[0013] Preferably, the displacement brush plate is fitted to the side wall of the fixed brush.

[0014] Preferably, the vertical plate is fitted to the top of the phosphating tank.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0016] 1. The present utility model is provided with a first displacement plate and a second displacement plate with a displacement frame at the top of the phosphating tank. When the servo motor operates, the screw rod rotates, and then the displacement block drives the first displacement plate and the second displacement plate to displace. At this time, the displacement frame reciprocates inside the phosphating tank, so as to stir and heat the phosphating solution inside the phosphating tank by using the displacement frame with a heating belt, so that the phosphating solution in the phosphating tank remains in a flowing state, the phosphating solution inside the phosphating tank can be heated more evenly, and further the contact phosphating between the phosphating solution and the surface of the high-carbon chromium bearing steel wire is better.

[0017] 2. When the present utility model performs the phosphating operation of the steel wire, the phosphated steel wire displaces from the wetting wheel to the wire guide wheel at the right end. At the same time, the steel wire is fitted between the fixed brush and the displacement brush plate of the displacement member. Therefore, when the steel wire displaces between the fixed brush and the displacement brush plate, the outer wall of the steel wire is brushed, so that the excess phosphating solution on the steel wire is brushed off and flows back into the interior of the phosphating tank, thereby realizing the cleaning of the excess phosphating solution attached to the steel wire, avoiding too much residual phosphating solution on the steel wire from contaminating the wire guide wheel at the right end, and reducing the contamination of the phosphating solution everywhere along with the displacement of the steel wire.
