Description

Technical Field

[0001] The utility model relates to the technical field of bellows processing, in particular to a spiral extrusion die for processing bellows. Background Art

[0002] Bellows refers to a tubular elastic sensitive element connected by foldable corrugated sheets along the folding and stretching direction. Bellows are widely used in instruments and meters. Their main purpose is to be used as a measuring element of pressure measuring instruments to convert pressure into displacement or force. The bellows has a thinner wall and higher sensitivity. The measuring range is from tens of Pa to tens of MPa. Its open end is fixed, the sealed end is in a free state, and an auxiliary spiral spring or reed is used to increase the elasticity. The corrugation requires an extrusion die during production and processing. The application number is "CN217968311U" disclosed in "A bellows forming die". The technical drawback of requiring subsequent cooling and hardening treatment has been solved, but in actual use, molds with similar structures still have many defects, such as the lack of pressurization and tightening processing when the mold is closed. When the mold is used to form the bellows, the mold may produce defective products due to loose fit, resulting in poor stability of the mold when processing the bellows. At the same time, the inside of the mold cannot be cleaned after use. When residues appear inside the mold, it will affect the subsequent molding process. For this reason, we have designed a spiral extrusion mold for processing corrugated tubes to solve the above problems. Utility Model Content

[0025] Based on the above-mentioned structural setting, the spiral extrusion die for processing the corrugated pipe is composed of an extrusion mechanism 1, a driving mechanism 2, a tightening mechanism 3 and a cleaning mechanism 4, wherein the extrusion mechanism 1 is for heating and extruding the raw materials during the corrugated pipe molding process, the driving mechanism 2 is for the molding process of the corrugated pipe, the tightening mechanism 3 is for tightening when the mold is matched, which is used to improve the quality of the corrugated pipe molding, and the cleaning mechanism 4 cleans the mold after the operation is completed.
