METHOD FOR PRODUCING A TWIN SCREW CYLINDER PROVIDED WITH A WEAR-PROTECTIVE LAYER

摘要

A method for producing a twin screw cylinder provided with or having a wear-resistant coating, in which two bores, which extend essentially parallel to each other and overlap each other, are produced in a cylinder and then two liners are inserted into the bores, the liners having an essentially C-shaped cross-section, continuing from each other in the overlapping region of the bores, forming the inner surface of the bores, and serving as a wear-resistant coating. First, a tubular liner is inserted into a first bore and then is cut to form the C-shaped cross-section in accordance with the diameter of the other bore and after this, a second tubular liner is inserted into the second bore and then is cut to form the C-shaped cross-section in accordance with the diameter of the inner surface in the first bore formed by the first liner.

1. A method for producing a twin screw cylinder provided with a wear-resistant coating (1), in which two bores (11, 12), extending essentially parallel to each other and overlapping each other, are produced in a cylinder and then two liners (21, 22) are inserted into the bores (11, 12), the liners having an essentially C-shaped cross-section, continuing from each other in an overlapping region (10) of the bores (11, 12) forming an inner surface (110, 120) of the bores (11, 12), and serving as a wear-resistant coating the method including first inserting a tubular liner (21) into a first bore (11) and then cutting to form the C-shaped cross-section in accordance with a diameter (D) of the other bore (12), and then inserting a second tubular liner (22) into the second bore (12) and then cutting to form the C-shaped cross-section in accordance with a diameter (A) of the inner surface (110) in the first bore (11) formed by the first liner (21).
