Description

Technical Field

[0001] The present invention relates to the technical field of mechanical manufacturing, and particularly relates to a device for filling a polymer coating on a parabolic thick-walled cylinder. Background Art

[0002] Inner wall spraying is a processing method often encountered in industrial production. In the past, when spraying the inner surface, low-molecular coatings were used. The coatings were relatively thin and could be sprayed with a spray gun. In order to spray the entire circumference, on the one hand, the workpiece had to be rotated and on the other hand, the spray gun had to be rotated. Rotating the workpiece required stopping the spraying work, manually rotating the workpiece by a certain angle, and then spraying with the spray gun again. This process had to be repeated three to four times to complete the spraying of the entire circumference, resulting in very low spraying efficiency. Rotating the spray gun required reciprocating swinging in the counterclockwise and clockwise directions, making the spraying operation very inconvenient. A paint can was installed at the end of the spray gun, and a high-pressure air pipe was also installed. For a certain series of products produced by our factory, the inner surface needs to be sprayed with a polymer coating. Its shape is a combination of a parabola-shaped axial cross-section at one end and a cylindrical shape at the other end. Its axial length is relatively long, with the axial length being 6 to 7 times the diameter, and the wall thickness is relatively thick, making the workpiece relatively heavy, weighing more than 150 kilograms, and impossible to be moved manually. When applying the polymer coating, the opening end needs to be upward first to make the axis perpendicular to the horizontal plane, then the polymer coating is filled into the workpiece to be coated, and then the filling port is closed. Then it is placed with the axis in a horizontal state and sent to a rotating machine by a lifting device to rotate, so that the polymer coating is evenly distributed until it solidifies. Since the coating used in this case is a polymer coating and cannot be sprayed with a spray gun, it relies on the natural flow of the coating rotating inside the inner wall to brush the coating on the inner wall. Therefore, a device is designed to first fill the polymer coating into the cylinder of the workpiece to be coated, and thus a device for filling a polymer coating on a parabolic thick-walled cylinder is designed, which can arbitrarily convert the axis of the workpiece to be coated within the range of 90° between the horizontal and vertical directions.
