Manufacturing method of a new type of rubber sleeve with built-in steel wire

Abstract

The invention discloses a manufacturing method for a novel rubber sleeve with a steel wire therein. The rubber sleeve comprises an inner tube rubber layer, a reinforcing wire layer and an outer-skin rubber layer; the reinforcing wire layer is woven on the outer surface of the inner tube rubber layer; and the outer-skin rubber layer covers the reinforcing wire layer. The manufacturing method comprises the following steps of: 1: straightening a spiral steel wire by a straightening mechanism, and cutting the spiral steel wire according to equal length; 2: carrying out impregnation treatment and heating curing treatment on the steel wire cut in the step 1; 3: putting the cured steel wire into a mould, adding a rubber material, and carrying out mould-pressing, hot-pressing and forming, thereby obtaining a semi-finished product; 4: thermally cooling the semi-finished product obtained in the step 3, and feeding the thermally cooled semi-finished product into an extruding mechanism to extrude and reinforce, thereby obtaining a crude finished product; 5: carrying out vulcanization treatment on the crude finished product obtained in the step 4; and 6: de-molding the crude finished product to obtain a finished product. According to the manufacturing method disclosed by the invention, process flow is simplified, production cost is reduced, bending resistance, torsion resistance, drawing force, compression resistance and the like of a guide tube are improved, and actual use requirements are met.

Description

technical field

[0001] The invention relates to a manufacturing method of a novel rubber sleeve with a built-in steel wire, and belongs to the technical field of medical equipment and manufacturing technology. Background technique

[0002] In the prior art, a steel wire is added to the tracheal tube to enhance the strength and softness of the tube and ensure the safety and smoothness of the breathing passage; at present, there are mainly two types of PVC tube with steel wire and rubber tube with steel wire, among which PVC material can only be used for one time For sexual use, and the affinity between PVC and the human body is poorer than that of rubber, there are potential adverse reactions. European and American countries have begun to phase out PVC materials for medical use. Extrusion equipment, complex process, high production cost.

[0003] The catheter with built-in steel wire can be applied to many medical devices, such as the laryngeal mask. In order to maintain the...
