Abstract

The invention discloses a manufacturing device of a vibration measuring tube. The manufacturing device comprises an upper mold and a lower mold. The middle portion of the lower mold is provided with asunken part capable of allowing the lower portion of the upper mold to be inserted in, and the lower portion of the upper mold is provided with a protrusion capable of being inserted into the sunkenpart. The lower portion of the upper mold is provided with an upper mold pressing groove used for cold-pressing the vibration measuring tube. The lower mold is provided with a lower mold pressing groove corresponding to the upper mold. The two sides of the sunken part of the lower mold are provided with roller molds capable of reducing friction force between the vibration measuring tube and the lower mold. The axes of the roller molds are perpendicular to the center line of the lower mold pressing groove. Each roller mold is provided with a circle of roller pressing groove. The invention further provides a manufacturing method of the vibration measuring tube. The manufacturing method comprises the steps of S1, feeding a vibration measuring tube blank into the lower mold pressing groove inthe upper surface of the lower mold, and driving the upper mold to move downwards to start to conduct cold-pressing; and S2, eliminating deformation generated in the cold-pressing process through a water expansion process. Through the manufacturing device and method of the vibration measuring tube, provided by the invention, the manufacturing precision of the vibration measuring tube can be improved.

Description

technical field [0001] The invention relates to the technical field of mold manufacturing, in particular to a manufacturing device and method for a vibration measuring tube. Background technique [0002] At present, the vibrating tube of the Coriolis mass flowmeter is one of its important parts. There are two main processing requirements: one is high precision itself, and the other is the consistency of the two vibrating tubes, so its processing is extremely difficult. Existing Coriolis mass flowmeter manufacturers generally use automatic pipe bending machines to process vibrating tubes. The automatic pipe bending machine realizes pipe bending through the rotation control of two axes and the feed control of one axis, in which the feed axis and the bending axis perform linear interpolation to complete the bending function, and the displacement of the two axes is determined by the bending The angle of the vibrating tube is determined, and the rotation axis is rotated and posi...
