Spring pipe entering equipment and spring hot prestressing method

According to the spring pipe entering equipment and the spring hot forced pressing method, the spring pipe entering equipment is provided with a sleeve assembly matched with the outer diameter of a spring and a main body used for compressing the spring into the sleeve assembly, and the sleeve assembly is detachably installed on the main body; the main body is provided with a machine body, a guide rod used for placing a spring and a press-in device used for pressing the spring into the sleeve assembly, and the guide rod and the press-in device are both assembled on the machine body; when the spring pressing-in process is carried out, the outer surface of the guide rod is sleeved with a spring, the outer surface of the spring is sleeved with the sleeve assembly, and the pressing-in device abuts against one tail end of the spring and generates compression force on the spring. And after the spring pressing-in procedure is completed, the whole spring is compressed in the sleeve assembly. The spring can be integral
