Dacromet treatment equipment and treatment method for fastener

Abstract

The invention discloses Dacromet treatment equipment and a treatment method for a fastener. The Dacromet treatment equipment comprises a conveying line, a lifting table and a tooling disc; the conveying line is provided with a front spraying chamber A, a cooling chamber, a sintering drying chamber, a rear spraying chamber B, a front preheating chamber and a rear preheating chamber; the front preheating chamber, the front spraying chamber A, the rear spraying chamber B, the rear preheating chamber, the sintering drying chamber and the cooling chamber are arranged in a linear mode according to the working procedure; the conveying line comprises a supporting frame, an upper-layer roller conveying chain mechanism and a lower-layer roller conveying chain mechanism, and the upper-layer roller conveying chain mechanism and the lower-layer roller conveying chain mechanism are arranged up and down; the upper-layer roller conveying chain mechanism is arranged at the upper portion of the supporting frame; and the lower-layer roller conveying chain mechanism is arranged at the lower portion of the upper-layer roller conveying chain mechanism. By the adoption of the technological process, the station steps are reduced, the operation time is saved, the running time of the whole Dacromet production line is shortened, the working efficiency is improved, and compared with an assembly line structure and technology in the prior art, the occupied space is reduced by half.

Description

technical field [0001] The invention relates to the technical field of surface treatment equipment, in particular to a Dacromet treatment equipment and a treatment method for fasteners. Background technique [0002] In the metal surface treatment industry, because the Dacromet treatment process has less pollution during the treatment process, and the products treated with it are resistant to high temperature, corrosion resistance, no crispness, and strong adhesion, it is especially suitable for surface coating of fasteners. Override processing. Moreover, with the continuous improvement and improvement of Dacromet equipment and technology, the surface quality of the coated product is gradually improved, and the pollutants are less and less, and even zero pollution can occur. [0003] However, the Dacromet assembly line equipment in the prior art is generally made into an "elliptical" or "U-shaped" layout structure. high cost. During the spraying work, according to the proc...

Problems solved by technology

[0003] However, the Dacromet assembly line equipment in the prior art is generally made into an "elliptical" or "U-shaped" layout structure. high cost

If a certain layer of spraying is too thick or cannot be preheated and sintered in time after spraying, it is easy to form sags, form "tumor collection" and uneven thickness, and it is easy to cause unqualified products

Moreover, due to the long logistics route, the whole process takes a long time, high energy consumption, high production cost and low production efficiency.
