Abstract

The invention discloses an inner wall smearing auxiliary device for corrugated pipe manufacturing and a using method of the inner wall smearing auxiliary device, and relates to the technical field of corrugated pipe manufacturing. The inner wall smearing auxiliary device for corrugated pipe manufacturing comprises a device body, and a controller is arranged on the front surface of the device body. According to the inner wall smearing auxiliary device for corrugated pipe manufacturing and the using method of the inner wall smearing auxiliary device, groove expanding treatment is conducted on the inner wall of the corrugated pipe before smearing operation, so that an air layer communicating with the coating layer and a corrugated pipe body exists between a coating layer and a corrugated pipe body, when the corrugated pipe is bent, part of coating is squeezed into the air layer, therefore external coating stress is relieved, and thus the effect of preventing cracking and falling of the coating layer is achieved; and during groove expansion treatment, threaded rod extrusion treatment instead of cutting treatment is adopted, so that the density of the corrugated pipe body on the top of the inner cavity of the air layer is relatively large, the position where the air layer is located is not prone to deformation when the corrugated pipe is bent, and therefore the service life of the air layer can be well guaranteed.

Description

Technical field [0001] The present invention relates to the field of corrugated tube manufacturing techniques, and is specifically a bellows manufacturing inner wall applicator assisting device and a method of use. Background technique [0002] The bellows refers to a tubular elastic sensitive element connected in a folded telescopic direction with a foldable wrinkle piece. The bellows are widely used in the instrumentation, and the main use is the measurement element of the pressure measuring instrument, and the pressure is converted into displacement or force. The corrugated pipe wall is thin, the sensitivity is high, and the measurement range is tens of Palace to dozens of MPa. Its opening end is fixed, the sealing end is in a free state, and the auxiliary coil spring or the reed increases elasticity, the bellows are in the manufacturing process, in order to ensure its quality, it is often desirable to apply the corresponding coating in its inner wall. [0003] In the prior ar...
