Manual corrugated pipe edge overturning tool

Abstract

The invention discloses a manual corrugated pipe edge overturning tool. The manual corrugated pipe edge overturning tool comprises a first sleeve and a second sleeve which are detachably connected; the end, away from the second sleeve, of the first sleeve is provided with a push rod insert-in port; the end, close to the second sleeve, of the first sleeve is provided with a knocking head stretch-out port; a push rod is arranged in the first sleeve in a penetrating manner; a knocking head is integrally formed on the end portion of the end, inserted into the first sleeve, of the push rod and canstretch into the second sleeve through the stretch-out port; the end, away from the first sleeve, of the second sleeve is provided with a corrugated pipe insert-in port in which a corrugated pipe is inserted in; the side wall of the second sleeve is further provided with a caliper gauge insert-in port in which a caliper gauge clamping assembly is inserted and connected; and the corrugated pipe canbe clamped and fixed by the caliper gauge clamping assembly. The manual corrugated pipe edge overturning tool solves the problems that a special convenient and fast manual tool for corrugated pipe end portion extruding and edge overturning is lacking in a current machining tool and equipment, and consequently the edge overturning operation of the corrugated pipe is tedious and wastes time are solved.

Description

technical field [0001] The invention relates to the technical field of bellows processing, in particular to a manual bellows flanging tool. Background technique [0002] Bellows refers to a tubular elastic sensitive element connected by foldable corrugated sheets along the direction of folding and stretching. The bellows has a thinner wall and higher sensitivity, and the measurement range is tens of Pa to tens of MPa. Its open end is fixed, and the sealed end is in a free state, and the auxiliary coil spring or reed is used to increase the elasticity. When working, under the action of internal pressure, it is elongated along the length of the pipe, so that the movable end produces a displacement that has a certain relationship with the pressure. The movable end drives the pointer to directly indicate the pressure. [0003] For stainless steel corrugated pipes, after processing, cutting and forming, it is often necessary to extrude both ends of the pipe fittings into neat ...
