Technical Field

The invention relates to double-wall corrugated pipe manufacturing equipment.

In particular to a double-wall corrugated pipe forming machine.

Background

The double-wall corrugated pipe is an invention pipe with an outer wall with an annular structure and a smooth inner wall, is firstly developed and succeeded in Germany in the early 80 s, and has been developed to a complete product series from a single variety through development and perfection for many years. At present, the production process and the use technology are mature, and the method has been greatly popularized and applied in China and developed countries such as Europe and America due to the excellent performance and the relatively economic cost.

The double-wall corrugated pipe production line generally comprises seven parts, namely an extruder, a machine head, a module, a forming machine, a spraying machine, a cutting machine and a stacking machine, wherein the module is of an aluminum casting structure so that the manufacturing cost is highest, and the occupied proportion of the module in the whole production line is the largest. The forming machine drives the sliding seat to operate through a gear or a chain wheel, and the sliding seat can be used for installing modules with different specifications to produce pipes with different specifications. Because several different sizes of pipes are produced on the same production line, the different sizes of modules need to be replaced frequently. The design concepts of various manufacturers are different, the width of the modules of the same type is slightly different, but the widths of the sliding seats are completely consistent, so the module widths explained later are all replaced by the theoretical width of the sliding seats.

The double-wall corrugated pipe aluminum casting modules commonly available on the market have six widths of 132mm, 152.4mm, 157mm, 175.93mm, 203.2mm and 527.8 mm. The transmission mode of the forming machine using the 152.4mm and 203.2mm module widths is simulated chain wheel and chain transmission, the rest is simulated gear rack transmission, and the 152.4mm module width is stopped at present.

The module of 132mm, 157mm is too narrow to be fit for arranging the corrugated pipe wave form of internal diameter more than 500mm, the module of 175.93mm is not fit for arranging the corrugated pipe wave form of internal diameter more than 1000mm, 527.8mm too wide processing and hoist inconveniently, 203.2mm module width is more suitable to arrange all corrugated pipe wave forms of internal diameter 100mm to internal diameter 1200mm, so the module market of this width keeps the volume the biggest at present, processes the supporting enterprise the most, the cost of manufacture is the lowest.

As shown in fig. 10, the transmission mode of the forming machine with the module width of 203.2mm is simulated sprocket chain transmission, the sprocket chain transmission has the problem of instantaneous acceleration, which is not as stable as rack and pinion transmission, and meanwhile, the forming machine adopting the simulated sprocket chain transmission is of a vertical structure, has very high center height, is inconvenient to operate and maintain, and is not as convenient to operate and maintain and stable as the forming machine adopting the simulated rack and pinion transmission.
