Description

Novel spray cooling device convenient to quick replacement pipe die

Technical Field

The utility model belongs to the technical field of cast tube pipe-line machining equipment, concretely relates to novel spray cooling device convenient to quick replacement pipe die.

Background

At present, large-diameter cast iron pipes are produced by casting with a hot mold centrifuge, and pipe dies become main molding equipment for the cast pipes of the hot mold centrifuge. When a cast iron pipe is produced, the inside of the pipe mould is impacted by high-temperature molten iron of more than 1300 degrees once, and the cooling speed of each section (the socket section, the pipe body section and the socket section) of the pipe mould is different, so that the metallographic structure of the cast iron pipe is different, and the quality of the cast iron pipe is influenced. General pipe die cooling device can carry out sectional type spray cooling to the pipe die outer wall, controls each segmentation cooling water flow through different inlet channels and governing valve to reach the even refrigerated effect of each section of pipe die. The largest amount of cooling water is in the pipe body section of the pipe die, common cooling pipelines of the pipe body section can be arranged on two sides of the pipe die, and a pipe body cooling pipeline support can be arranged on a large base below the pipe die. When the pipe die is replaced, the centrifuge cover body and the pipe die spraying device need to be removed or disassembled, and the largest work for disassembling the spraying device is the pipe body spraying mechanism. But the pipe body spray cooling pipeline needs to be completely disassembled to make the pipe die replacement space. Therefore, the pipe die cooling pipeline support is detached when the pipe die is replaced every time, the workload is increased, the pipe die replacement time is prolonged, and the production efficiency of the cast pipe is reduced.

The existing pipe die spraying device is influenced by a pipe body spraying structure, and when the pipe die is greatly remodeled (namely, the pipe die and the supporting wheel set are simultaneously replaced), the pipe body spraying mechanism and the bell and spigot spraying mechanism are required to be detached, and particularly, the pipe body spraying mechanism is required to be disassembled and assembled, so that the pipe die spraying device is very complicated. When the spray head is vertical to the pipe dies for spraying, the cooling efficiency is optimal, but because the specification is more from DN1100 to 3000, the span is larger, the spray head of the traditional spray cooling device can not be vertical to all the pipe dies, and the cooling efficiency is reduced.
