Abstract

The invention aims to provide a double-wall corrugated pipe die head deflected wall adjustment device and a deflected wall adjustment method. The double-wall corrugated pipe die head deflected wall adjustment device comprises: a head stock, a die head assembly, an inner deflected wall adjustment apparatus and an outer deflected wall adjustment apparatus. The die head assembly consists of: an innercore that is equipped with a mesopore and has the rear end connected to the head stock, and an inner sleeve and an outer sleeve that are sleeved outside the inner core in order and have the rear endsdetachably connected to the head stock respectively. An inner wall material stock channel is formed between the inner core and the inner sleeve, and an outer wall material stock channel is formed between the inner sleeve and the outer sleeve. The double-wall corrugated pipe die head deflected wall adjustment device has the characteristics of convenient and fast deflected wall adjustment.

Description

technical field [0001] The invention relates to the field of plastic corrugated pipe manufacturing, in particular to a device for adjusting a partial wall of a double-wall corrugated pipe die head and a method for adjusting a partial wall. Background technique [0002] The utility model of Chinese patent application number: CN201120200943.0 discloses a kind of machine head that produces double-wall corrugated pipe, comprises base (5) and extruder screw assembly assembly (1) installed on the base, speed change machine case ( 2), feeding mechanism (3), mold device assembly (4); an organic base (6) is arranged under the base (5), there is a guide rail (6-1) under the base (6), and a guide rail (6-1) is arranged under the base (5). Guide groove (5-1) is arranged, and guide groove (5-1) forms sliding fit with guide rail (6-1). The traditional mold device assembly for producing double-wall corrugated pipes has the problem of troublesome and time-consuming adjustments due to the l...
