Spraying device for nodular cast iron pipe

Abstract

The invention provides a spraying device for a nodular cast iron pipe, and belongs to the technical field of cast pipe spraying. The spraying device comprises a spraying mechanism, a horizontal-movingmechanism, a rotating mechanism and a control mechanism; the spraying mechanism is used for spraying a nodular cast iron pipe bell end in the circumferential direction, and the spraying position of the spraying mechanism for the nodular cast iron pipe bell end can be adjusted; the horizontal-moving mechanism is arranged on one side of the spraying mechanism, the nodular cast iron pipe is placed on the horizontal-moving mechanism, and the horizontal-moving mechanism is used for pushing the nodular cast iron pipe bell end to axially and horizontally move to the spraying mechanism; the rotatingmechanism is arranged above the horizontal-moving mechanism and used for driving the nodular cast iron pipe to rotate in the circumferential direction; the spraying position of the spraying mechanismis adjusted by means of the rotating mechanism and the horizontal-moving mechanism; and the control mechanism is used for controlling the spraying speed of the spraying mechanism and the rotating speed of the rotating mechanism. The spraying device for the nodular cast iron pipe has the technical effects that the nodular cast iron pipe bell end is evenly sprayed, manual spraying is not needed, mechanical automatic spraying is easy to implement, the spraying quality is easy to control, spraying dead corners are avoided, and the labor intensity is relieved.

Description

technical field [0001] The invention belongs to the technical field of cast pipe spraying, and more specifically relates to a nodular cast iron pipe spraying device. Background technique [0002] The socket spraying of ductile iron pipes is a key link in the product processing chain. Generally, it is sprayed manually. Due to the different proficiency of each person, there will be unstable factors for the spraying quality of the cast pipe sockets, such as spraying Factors such as the thickness and uniformity of the coating are determined manually by one's own experience, and the quality control of the spraying is not good, which will eventually lead to uneven quality of the entire product. Moreover, when the manual brushing operation time is long, it is easy to have dead angles of brushing, resulting in insufficient brushing. In order to avoid dead angles, operators will repeatedly paint, resulting in waste of raw materials and low work efficiency. Furthermore, the manual lo...
