Abstract

The invention discloses a steel ring edge folding machine which comprises a rack. The rack is internally provided with a transmission mechanism. The rack is provided with a locating core model for being in cup joint with a steel ring, an edge folding mechanism for rolling and pressing the steel ring and an arc pressing mechanism for downwards pressing the steel ring. The mandrel of the locating core model is connected with the transmission mechanism and driven by the transmission mechanism to rotate. The external circumference of the locating core model is in cup joint with the steel ring. One side of the locating core model is provided with the edge folding mechanism for applying force to the top end of the steel ring in an inclined mode from top to bottom, and the edge folding mechanism makes the top end of the steel ring form an inwards-folded edge. The arc pressing mechanism for downwards applying force to the inwards-folded edge at the top end of the steel ring is arranged above the locating core model and makes the inwards-folded edge form a downward arc groove by moving downwards. The steel ring edge folding machine has the advantages of being simple in structure, convenient to fabricate, low in cost, good in edge folding effect and arc pressing effect, not prone to breakage and the like.

Description

technical field

[0001] The invention relates to an edge folding machine for pipe steel ring joints, in particular to a steel ring edge folding machine. Background technique

[0002] The sewer pipe is a pipe used to discharge sewage or rainwater. It is used to collect and discharge domestic wastewater generated by cities and industrial wastewater generated by industry. The existing sewer pipe is mainly a gravity sewer system, and its sewer pipe is inclined downward. , where the flow of sewage depends on gravity. In the pressure sewer system, overpressure is used to transport sewage through small-diameter sewer pipes. The advantage is that it is simple and convenient, but there are also problems of easy damage and water leakage, especially the junction of two water pipes. , Due to corrosion and thermal expansion and contraction, the joints are deformed and gaps appear, resulting in liquid leakage and causing great damage to the living environment.
