Embodiment Construction

[0023] will now refer to Figure 1-6 Preferred embodiments of the present invention will be described in detail.

[0024] see figure 1 ,in figure 1 The upper left part is an enlarged cross-sectional view of a straight rubber tube covered with a polyester film 5, a process for processing rubber shaped tubes, including the following steps:

[0025] see figure 1 , according to the requirements of product inner diameter, wall thickness, length and blasting pressure, wrap the inner layer rubber 2, the skeleton layer 3 and the outer layer rubber 4 on the straight pipe core 1 to form a rubber straight pipe on the straight pipe core. Straight pipe core and rubber straight pipe are fixed on the machine;

[0026] Coating the pre-prepared polyester film 5 from the straight tube core 1 and one end of the rubber straight tube;

[0027] Put the coated rubber straight pipe and the straight pipe core 1 together into a hot air vulcanization tank for primary vulcanization, and no pressure ...

Abstract

The invention discloses a rubber special pipe processing technique which comprises the following steps: forming a rubber straight pipe on a mould core and wrapping with a polyester film; performing primary forming vulcanization in a vulcanization tank; demoulding the rubber straight pipe, sleeving in a special mould core and wrapping with a polyester film; performing secondary vulcanization; and demoulding the rubber pipe after the secondary vulcanization to obtain the finished product. According to the invention, the problems of long production period of small-scale products, high processing cost and changeable size in sample piece stage causing batch production unavailable are solved. The equipment is simple and easy to operate and does not need excessive labor power and material resources. In addition, through the technique, the problems that the requirement on burst pressure is high and the special pipe needs to be wound by a multi-layer framework are solved.

Description

technical field [0001] The invention relates to a processing technology for special-shaped rubber pipes, in particular to a processing technology for special-shaped rubber pipes in small batches with multiple varieties by secondary vulcanization. Background technique [0002] The traditional multi-layer winding rubber straight pipe is vulcanized by hand-wrapping and then wrapped with water-wrapped cloth. For example, the patentee Liu Jianping’s patents CN2878852Y and CN1302912C disclose rubber pipes made by this production process. The above two patent documents have passed References are incorporated here. This process has the following disadvantages: (1) the water-wrapped cloth will easily cause the air bubbles in the tube blank to escape easily, resulting in defects such as delamination of the inner rubber layer; (2) the rubber tube covered by the water-wrapped cloth is easily separated from The outer layer of rubber is bonded together and it is difficult to remove the m...
