Description

Technical Field

[0001] The utility model relates to the technical field of superchargers, in particular to a gas-buffered energy-saving supercharger. Background Art

[0002] A gas-liquid booster is a product that provides a high-pressure power source. It uses a lower gas source pressure to push a large-area piston, and a small-area rod pushes the hydraulic oil at the other end. The hydraulic oil in the cylinder expands to form high-pressure hydraulic oil, thereby driving other actuators.

[0003] Gas-liquid boosters can convert lower gas pressure into higher hydraulic pressure, achieving efficient pressure amplification and meeting the needs of some applications that require high hydraulic pressure. Currently, gas-liquid boosters are widely used in various pressurized machinery. They are widely used in pressurized processing industries such as stamping and forging. For example, in the stamping production of automotive parts, gas-liquid boosters can provide sufficient pressure to stamp metal sheets and process them into auto body parts. For example, during the machining process, gas-liquid boosters can provide power for hydraulic clamps to achieve clamping of workpieces.

[0004] Currently, in many situations where high-pressure boosting is required, a Beili supercharger can be used. However, it has certain disadvantages. A Beili supercharger generally contains multiple piston cavities. During the operation of the Beili supercharger, it is necessary to supply air to multiple piston cavities, which consumes a lot of gas, making the Beili supercharger consume a lot of energy. When multiple pistons retract, they will hit the inner wall of the cavity at the same time, generating a lot of noise and polluting the environment. Utility Model Content

[0044] The air-buffered energy-saving supercharger provided by the embodiment of the present invention has the following characteristics: when the piston rod 14 retracts, part of the gas in the piston chamber can be discharged into the gas tank 2; since the one-way valve 3 is arranged between the gas tank 2 and the external gas source, the gas inside the gas tank 2 will not be discharged into the atmosphere through the one-way valve 3; when pressurizing again, the gas in the gas tank can be reused, saving gas and energy; when retracting, the closer the piston rod 14 is to the end of the return stroke, the higher the pressure in the gas tank, the smaller the piston speed, and the smaller the impact force of the piston on the inner wall of the booster cylinder assembly 1; the gas tank plays a certain buffering role, which can effectively reduce noise and make the environment cleaner; at the same time, it can achieve high outlet pressure, save gas and energy, and effectively reduce the cost of use.

[0045] In one embodiment, the at least one piston chamber includes at least one first piston chamber 12; the first piston chamber 12 includes two chambers divided by the piston, which are referred to as the first drive chamber 121 and the first retraction chamber 122; Figure 2 As shown, specifically:

[0047] In one embodiment, the piston chamber further includes at least one second piston chamber 13; the second piston chamber 13 includes two chambers divided by the piston, which are referred to as the second driving chamber 131 and the second retraction chamber 132; Figure 2 As shown, specifically:

[0048] The second driving chamber 131 is used to communicate with an external air source; the second retraction chamber 132 is used to communicate with an external air source.

[0049] In one embodiment, the above-mentioned gas buffer energy-saving supercharger, referring to Figure 1 As shown, the boost cylinder assembly 1 further includes an end cover 11. The end cover 11 includes a first end cover 111 and a second end cover 112. The positions of the first end cover 111 and the second end cover 112 are shown in FIG. Figure 2 shown.

[0050] In the embodiments of the present invention, the first piston chamber 12 and the second piston chamber 13 are respectively two types of piston chambers. In practice, the air-cushioned energy-saving supercharger includes at least one first piston chamber 12 and at least one second piston chamber 13. It should be noted that at least one of the retraction chambers of the first and second piston chambers 12, 13 is connected to an external air source, enabling the first and second retraction chambers 122, 132 to retract the piston rod 14.

[0051] For example, under normal circumstances, the piston rod 14 can be retracted by connecting the second retraction chamber 132 to an external air source and the first retraction chamber 122 to the external atmosphere;

[0052] The retraction of the piston rod 14 can also be achieved by adopting a method in which the second retraction chamber 132 is connected to the external atmosphere and the first retraction chamber 122 is connected to the external air source.

At the same time, the second piston 133 drives the first piston 123 to retract through the piston rod 14, and the gas in the first drive chamber 121 is discharged back to the gas storage tank 2, and the external atmosphere enters the first retraction chamber 122.

[0083] The following is a specific example to illustrate the working process of the above-mentioned gas buffer energy-saving supercharger. Figure 1As shown, the gas-buffered energy-saving supercharger of this example includes an oil chamber 7, an air storage tank 2, a connecting plate component 9, an oil tank 8 and two piston chambers.

[0084] Among them, one of the two piston chambers is set as the first piston chamber 12, and the other is set as the second piston chamber 13;

[0085] Reference Figure 3 As shown, the external air source, the retraction air path 6, and the second retraction chamber 132 are connected in sequence; the external air source, the one-way air path 41 (with a one-way valve 3 provided therein), the air storage tank 2, the two-way air path 42, and the first drive chamber 121 are connected in sequence; the external air source, the second drive air path 5, and the second drive chamber 131 are connected in sequence; and the first retraction chamber 122 is in communication with the external atmosphere.

[0086] Reference Figure 1 As shown, an oil chamber 7 is provided at the end of the extension stroke of the piston rod 14 ; an oil tank 8 is connected to the oil chamber 7 for replenishing oil to the oil chamber 7 .

[0087] The initial state of the air cushion energy-saving supercharger in this example is the retracted state. Figure 1 As shown, the positions of the various components are in the retracted state.

[0088] The following briefly describes the working process of the gas buffer energy-saving supercharger of this example:

[0089] The boosting process of the gas buffer energy-saving supercharger: refer to Figure 2 As shown in FIG. 1 , the positions of various components during the pressurization process are as follows: an external air source supplies air to the air tank 2 via the one-way air path 41, and the air tank 2 supplies air to the first drive chamber 121 via the two-way air path 42; at the same time, an external air source supplies air directly to the second drive chamber 131 via the second drive air path 5; in this case, the first drive chamber 121 drives the first piston 123, and the second drive chamber 131 drives the second piston 133, thereby achieving double-force pressurization and simultaneously pushing the piston rod 14 out to the oil chamber 7, thereby discharging the high-pressure oil from the oil chamber 7 to the actuator.

[0090] Retraction process of the air cushion energy-saving supercharger:

[0091] An external air source supplies air to the second retraction chamber 132 through the retraction air path 6. The first piston 123 and the second piston 133 are forced to drive the piston rod 14 to retract. The gas in the second drive chamber 131 is discharged to the atmosphere through the second drive air path 5, and the gas in the first drive chamber 121 is discharged back to the gas storage tank 2 through the two-way air path 42. Since the one-way air path 41 is provided with a one-way valve 3, the gas in the air tank 2 will not be discharged into the atmosphere through the one-way air path 41, and this part of the gas in the air tank 2 can be reused when pressurizing again; at this time, the air pressure inside the air tank 2 increases, and the degree of the air pressure increase depends on the ratio of the volume of the air tank 2 to the volume of the first drive chamber 121. The larger the ratio, the smaller the air pressure increase in the air tank 2; when the piston rod 14 is closer to the end of the return stroke, the greater the air pressure in the air tank 2, and the smaller the air pressure difference with the second retraction chamber 132, so that the return speed of the piston is smaller, so that the air tank 2 plays a buffering role, preventing the piston from hitting the second end cover 112 of the boost cylinder assembly 1.

[0092] The re-pressurization process of the air-buffered energy-saving supercharger: the external air source at the first drive pipeline 4 can no longer supply air, or it can still supply air to the air tank 2 through the one-way air line 41. However, during this process, since the air pressure inside the air tank 2 is greater than the pressure set by the external air source, the first drive chamber 121 will no longer consume the gas provided by the external air source. The air tank 2 supplies air to the first drive chamber 121 through the two-way air line 42; at the same time, the external air source directly supplies air to the second drive chamber 131 through the second drive air line 5; in this case, the first drive chamber 121 drives the first piston 123 and the second drive chamber 131 drives the second piston 133, pushing the piston rod 14 out; when the piston rod 14 moves to the end of the extension stroke, the internal air pressure of the air tank 2 and the first drive chamber 121 returns to the initial air pressure. In this way, it is possible to achieve double-force supercharging and save air and energy while consuming only one piston chamber's gas. Since the air pressure inside the first drive chamber 121 is relatively high when the first piston 123 just starts to move, an air intake throttling component can be set in the two-way air path 42, or an exhaust throttling component can be set at the outlet of the first retraction chamber 122 to steadily increase the air pressure in the first drive chamber 121 and reduce noise.

[0093] Obviously, those skilled in the art may make various modifications and variations to the present invention without departing from the spirit and scope of the present invention. Thus, if such modifications and variations fall within the scope of the claims of the present invention and their equivalents, the present invention is intended to include such modifications and variations.
