Problems solved by technology

In the hydraulic bulging process currently used at home and abroad, the typical forming equipment is a three-way special hydraulic press, which consists of a vertical pressure cylinder that provides clamping force, two horizontal thrust cylinders that provide axial thrust, a supercharger that generates high pressure, and The supporting hydraulic system and control system are composed of complex structure and high cost, which has become the main bottleneck restricting the wide application of hydraulic bulging technology

Embodiment Construction

[0015] exist figure 1 , figure 2 It is an embodiment disclosed by the present invention. The mold system of the ultra-high pressure hydraulic bulging integrated device is composed of three parts: a supercharger, a liquid charger, and a sliding bulging mold. The bulging mold adopts a sliding type, and the horizontal parting mold is composed of a bulging upper mold 20, a bulging lower mold 22, a guide cylinder 23, and a control mold 4. The cavity of the bulging upper mold 20 and the bulging lower mold 22 is designed according to the profile of the bulging part, and the guide posts 19 on the lower mold and the guide holes 18 on the upper mold ensure the installation accuracy. The guide cylinder 23 ensures the guidance of the bulging upper mold and the bulging lower mold, and provides mold clamping force. If the bulging part adopts two bulging processes, during the first bulging, a control mold 4 needs to be installed between the bulging upper mold and the bulging lower mold to...

Abstract

The integrated super high pressure hydraulic bulging apparatus for rotary shell part consists of three systems, including a mold system, a hydraulic system and a control system. It has the functions of fast liquid filling, generating variable high pressure, circularly filtering the liquid, automatic control, etc. It has mold system with integrated supercharger and liquid filler, interference fitting and combined sealing for high pressure dynamic sealing, and safe operation environment. The present invention realizes high pressure hydraulic bulging for rotary shell part with common hydraulic press and common hydraulic source, has lowered requirement in apparatus, lowered power consumption and lowered cost, and is favorable the wide application of hydraulic bulging technology.

Description

technical field [0001] The invention belongs to a hydraulic bulging (internal high-pressure forming) device for rotary shell parts, which uses a common hydraulic pressure source of an ordinary hydraulic machine to realize ultra-high pressure hydraulic bulging of rotary shell parts, adopts new sealing measures, automatically controls the forming process, and has a safe working environment. Background technique [0002] Since the parts produced by hydraulic bulging technology have the advantages of reducing weight, reducing the number of molds, increasing strength and rigidity, etc., they have been used in aerospace and transportation fields and have broad prospects. The success or failure of the hydraulic bulging process mainly depends on three factors. One is the need to equip special equipment for hydraulic bulging with a high-pressure source. One-time forming parts, the third is to ensure reliable dynamic sealing during ultra-high pressure bulging. In the hydraulic bulgin...
