Problems solved by technology

Therefore, this process cannot avoid the extrusion deformation of the tube blank when it is closer to the fixed end during the sleeve setting process, resulting in the deviation of the wall thickness of the tube blank.
For some tube blanks with smaller diameters or more complex shapes, such as more curved parts, it is more difficult to implement the expansion sleeve at the fixed end, resulting in long time-consuming and low efficiency of the process, which is easy to cause the rubber tube to break. inconsistent wall thickness

Abstract

The invention relates to the technical field of rubber pipe preparation, in particular to a rubber pipe forming auxiliary device and a rubber pipe forming auxiliary technology and application thereof.The rubber pipe forming auxiliary device comprises a fixing end and a sleeving end. At least one part of the auxiliary device is arranged to be the rubber pipe expanding part. The rubber pipe expanding part is arranged at the path from the sleeving end to the fixing end. According to the rubber pipe forming auxiliary device and the rubber pipe forming auxiliary technology and application thereof,time consuming in the forming technology is effectively reduced, efficiency is improved, and the thickness of the wall of the rubber pipe is consistent.

Description

technical field [0001] The invention relates to the technical field of rubber hose preparation, in particular to a rubber hose forming auxiliary device, a rubber hose forming process and applications thereof. Background technique [0002] The hose preparation process usually involves expanding the diameter of the end of the hose, facilitating the connection between the hoses and the convenience of the connection between the hose and the equipment. The preparation process is usually that before the vulcanization of the rubber hose, the tube blank of the obtained rubber hose is sleeved on the mandrel, and the end of the mandrel is usually fixed on a certain device to facilitate the sleeve of the tube blank. [0003] In most cases, the diameter-expanding part is set at the fixed end of the mandrel and a certain device to avoid deformation of the tube blank during the process of gradually wrapping the mandrel when it is set at the sheathing end of the mandrel. Therefore, this p...
