Abstract

The invention relates to a mandrel-retracting machine for impregnating a bent pipe. The mandrel-retracting machine is characterized by comprising an installation base plate and an electric control cabinet, wherein the installation base plate is fixedly provided with a cylinder fixed plate on which an elbow mandrel retracting drive cylinder is arranged; the elbow mandrel retracting drive cylinder is connected with a jacking spring mechanism; the installation base plate is fixedly provided with an elbow mandrel fixed seat, a supporting rod and an upper cylinder installation plate; a compression cylinder is arranged at the bottom of the upper cylinder installation plate; the lower end part of a piston rod of the compression cylinder is connected with a cylinder travel switch stop block and a mandrel-fixed upper press head; the supporting rod is provided with a travel switch X1 through a connecting piece; a travel switch bracket provided with a travel switch X2 is fixed on the installation base plate; and both the travel switch X1 and the travel switch X2 are connected with the electric control cabinet. The invention has the advantages that the electric control and the mechanical driving are organically combined, so the invention can substantially reduce the labor intensity of operators and improve the processing efficiency for impregnating the bent pipe.

Description

technical field [0001] The invention belongs to the field of pipe body processing machinery, in particular to a mandrel stripping machine for impregnated bent pipes. Background technique [0002] At present, the aortic cannula used in medical clinical cardiac surgery is made by impregnating the plastic material on the elbow-shaped mandrel to make the base tube, cooling naturally, and then lining the outer wall of the base tube with a stainless steel spiral reinforcement, and then performing a second Dip wrap composition. The bent pipe after dipping needs to withdraw from the elbow-shaped mandrel. At present, the traditional method is to use the manual operation method, that is, to use the auxiliary rod withdrawal plate with a through hole on it, and put the rod withdrawal auxiliary plate on the dipped mandrel. After the mandrel part with the bent pipe, make the auxiliary rod withdrawing plate close to the first port of the bent pipe, and fix the mandrel part of the bent pip...
