Embodiment 1

[0030] refer to figure 1 A relay-type high-pressure pressurization system shown includes a water inlet valve 1, a filter mechanism, a booster part, a high-pressure control valve 16, and a bulged member 15; the water inlet valve 1, filter mechanism, booster part and The high-pressure control valve 16 is arranged sequentially on the pipeline between the water inlet and the bulging member 15; the booster part is provided with at least two sets of high-pressure boosters connected in parallel.

[0031] In a specific application, the water inlet valve 1 is opened, and the liquid for bulging passes through the filter mechanism, and then enters one of the high-pressure superchargers in the supercharging part for supercharging, and the other high-pressure superchargers are in a standby state. The pressurized liquid for bulging enters the bulged part 15 through the high-pressure control valve 16, and implements a forming process on the bulged part 15. When the working high-pressure sup...

Embodiment 2

[0034] refer to figure 1 A relay-type high-pressure supercharging system is shown. On the basis of Embodiment 1, the filter mechanism includes a first one-way valve 2, a filter 3 and a differential pressure switch 4; the first one-way valve 2. The filter 3 and the differential pressure switch 4 are connected in parallel on the pipeline between the water inlet valve 1 and the pressure booster.

[0035] In actual use, after the water inlet valve 1 is opened, the bulging liquid enters the pressurized part after passing through the filter. If the filter 3 is clogged, the differential pressure switch 4 sends a signal, prompting that the filter 3 needs to be replaced. In order to ensure production needs, the liquid may not pass through the filter 3, but enter the pressurization part through the first one-way valve 2. Generally, the set pressure of the first one-way valve 2 is higher than the signaling pressure of the differential pressure switch 4 to ensure that under normal condi...

Embodiment 3

[0037] refer to figure 1 The relay-type high-pressure supercharging system shown is based on the first embodiment: the supercharging part includes a first supercharging mechanism and a second supercharging mechanism; the first supercharging mechanism and the second supercharging mechanism The booster mechanism is connected in parallel on the pipeline between the filter mechanism and the high pressure control valve 16 .

[0038] In actual use, the supercharging part is provided with a first supercharging mechanism and a second supercharging mechanism. When the bulging liquid filtered by the filter 3 in the filtering mechanism enters the supercharging part, the first supercharging mechanism in the supercharging part The supercharging mechanism or the second supercharging mechanism starts to work, and when the first supercharging mechanism or the second supercharging mechanism reaches the limit, it stops working and resets, and at the same time the second supercharging mechanism ...

Abstract

The invention belongs to the technical field of high-pressure liquid expansion forming, and particularly relates to a relay type high-pressure pressurization system and method. The device comprises a water inlet valve, a filtering mechanism, a pressurizing part, a high-pressure control valve and a bulged part, the water inlet valve, the filtering mechanism, the pressurizing part and the high-pressure control valve are sequentially arranged on a pipeline between the water inlet and the bulged part; and the pressurizing part is at least provided with two sets of high-pressure superchargers which are connected in parallel. The two sets of high-pressure superchargers arranged on the supercharging part can carry out relay type alternate supercharging. The pressurization system has the infinite supercharging volume, and the technical problem that the supercharging volume of a traditional supercharger is limited is fundamentally solved.

Description

technical field [0001] The invention belongs to the technical field of high-pressure liquid expansion forming, and in particular relates to a relay-type high-pressure boosting system and method. Background technique [0002] Lightweight, high-performance structural parts are widely used in aviation, aerospace, navigation, automobiles, rail transit and other fields. Studies have shown that the performance of structural parts directly affects the safety, reliability, maneuverability, carrying capacity, payload, fuel consumption and other indicators of the vehicle. Ultra-high pressure liquid bulge forming is an advanced manufacturing technology developed to meet the above-mentioned industrial requirements for high-quality manufacturing of structural parts. The basic principle of forming is to use the pipe as the blank. By applying ultra-high pressure liquid and axial force inside it, the tube blank is pressed into the mold cavity to form it into the desired workpiece. However...
