PE double-wall corrugated pipe forming principle _PE pipe production line

1, the machine

Corrugated pipe forming machine is the key equipment to produce PE double-wall corrugated pipe, pipe quality and production. PE double-wall corrugated pipe forming methods also varied, and different from other pipe molding equipment.

According to the module installation methods can be divided into: vertical and horizontal two kinds

Vertical molding equipment can make the module opening up and down, and covers an area of small, compact layout, module replacement more difficult, however, especially large diameter module replacement; Horizontal molding equipment can make the module level opening and closing, covers an area of large, but a replacement module is vertical. And module programming the cooling water circulation channel, with water as cooling medium, greatly improved production speed.

According to finalize the design method can be divided into: two current pressure already set and vacuum system some manufacturers choose to finalize the design method of air pressure equipment, namely to compressed air through the nose on the mold core support rod and fixed on the mold core plug to the outer pipe inner chamber, make the pipe close to on the module, a wave. This equipment produces the products can be so arbitrary cross section, will also be able to progress the quality of the corrugated pipe, cutting thickness errors in the high and low corrugated width, and reduce waste, also greatly simplifies the products within the layout of cooling equipment and the layout of the nose. But moved to compressed air pipes of wave differ, the appearance of goods are harder to control.

2, molding module

PE double-wall corrugated pipe forming machine mould first is module, its resolution of pipe layout and scale. Follow different molding methods, as well as module movement track, the layout of the module are also different. Most of the current production line is a module vacuum material adsorption on the table in the mould, the module must have a vacuum with channel. The layout of the molding module directly resolution of pipe ring stiffness.

Here today by small make up me to brief introduce for us about PE double-wall corrugated pipe outer wall common problem analysis, expect to help us in the future use of time to be able to use, please follow our small make up together to know the following content is introduced.

One, the outer wall of the outer wall forming or not

1, the outer wall material temperature is low, the external layer or the nose heated;

2, small amount of extrusion tube billet, adjusting extrusion;

3, the normal charge is too small, adjust the normal air pressure, such as adjusting the invalid check filling pores have blocked normal appearance, normal air tube is a flat to repair;

4, the outer wall partial wall, thin side will absorb the break, to adjust;

5, molding module device is not in place, the wall broken, make its center adjust molding module;

6, die and sizing set is not in the middle of the molding module, adjust the forming machine and the machine

First, make its head in the module center;

7, with impurities in the material, to view the material disposal;

Adjustment, the outer wall partial: outer mouth mode: on the nose of the up and down or so four regulating screw bolt, outer extrusion of evenness.
