A kind of production equipment for inflatable thermoforming of pipe fittings

Abstract

The invention belongs to the technical field of pipe fitting forming, and particularly relates to pipe fitting air expansion heat forming production equipment. The pipe fitting air expansion heat forming production equipment comprises an installing body, an upper die, a lower die, a forming module, a seal head, a gas conveying pipeline and a ventilation pipeline. The upper die and the lower die are arranged in an up-down manner, and the upper die can do the die opening and closing movement relative to the lower die. The forming module is located between the upper die and the lower die and usedfor pipe fitting forming, and a closed cavity is defined by the seal head, the forming module, the upper die and the lower die. The gas conveying pipeline communicates with the forming module and isused for inflating high-pressure gas into the closed cavity so that a pipe fitting can formed through air expansion. The ventilation pipeline communicates with the forming module and is used for cooling the closed cavity. By means of the pipe fitting air expansion heat forming production equipment, the pipe fitting can be subjected to continuous three-time forming, the forming speed is high, efficiency is high, the resilience value is small, precision is high, and the pipe fitting air expansion heat forming production equipment can be used for forming of pipe fittings with large mechanical material strength.

Description

technical field [0001] The invention belongs to the technical field of pipe fitting forming, in particular to a production equipment for pipe fitting inflatable thermoforming. Background technique [0002] Pipe fittings are components that play the roles of connection, control, direction change, diversion, sealing, support, etc. in the pipeline system; metal conductor pipe fittings of various shapes and sizes are widely used in aerospace, automotive, petrochemical, and power systems. Applications. These metal conductor pipe fittings often have complex and irregular surface shapes, and different parts of the same part have different cross-sectional shapes. It is difficult to obtain pipe fittings of these complex shapes through direct machining. At the same time, pipe fittings The mechanical strength of the material is too high, and it is also difficult to form. In order to make the simple shape of the tube blank into a complex tube that meets the precision and quality requir...

Problems solved by technology

"This technical solution is mainly aimed at forming pipe fittings with strong mechanical materials. Although the molding pressure provided by the press is reduced by heating the pipe fittings, due to the excessive strength of the mechanical materials and one-time molding, it still requires a large molding pressure, the requirements for molding equipment are still relatively high
