Description

Technical Field

[0001] The invention relates to the technical field of vehicle intercooler systems, and in particular to an intercooler air chamber and main plate pressing tool and a pressing method thereof. Background Art

[0002] For supercharged engines, the intercooler is an important component of the supercharging system. The main function of the intercooler is to guide the high-temperature and high-pressure gas at the outlet of the turbocharger compressor into the inlet of the intercooler air chamber, dissipate heat through heat conduction, and keep the temperature at the outlet of the intercooler within a low temperature range suitable for the engine intake. At this time, the air density is higher, thereby increasing the engine's charging efficiency and providing the engine's output power. Usually the intake temperature of the intercooler will be higher than 150°C.

[0003] The connection between the intercooler air chamber and the main plate is achieved by matching the size relationship and the compressibility of the gasket to ensure the assembly seal. In order to meet the requirements of lightweight of the whole vehicle, the intercooler air chamber is usually a plastic air chamber. At the same time, in order to meet the space layout requirements of the whole vehicle, the shape of the intercooler air chamber is mostly irregular. When the air chamber is pressed down to assemble with the main plate, the sealing surface of the air chamber will be unevenly stressed, that is, the downward stroke is inconsistent, which will cause the overall compression of the gasket to be uneven, and finally lead to the failure of the long-term high temperature test of the intercooler. After analysis, it was found that the main reason for its failure was that the compression resilience of the gasket would be significantly deteriorated after long-term high temperature resistance. The places where the gasket was compressed too much could not rebound normally after high temperature resistance, thus causing leakage. More commonly, it takes a lot of time to adjust the air chamber downward pressure tooling for each replacement trial. Summary of the invention

[0004] The purpose of the present invention is to address the deficiencies of the above-mentioned technology and provide a pressurizing tool for an intercooler air chamber and a main plate and a pressurizing method thereof, which can balance the pressure on the sealing surface of the intercooler air chamber, ensure uniform compression of the sealing gasket, and greatly reduce the adjustment time.

[0005] To achieve the above-mentioned purpose, the intercooler air chamber and main plate pressing tooling designed in the present invention includes a fixed base plate and an air chamber aluminum mold. The air chamber aluminum mold is a hollow structure. The four corners of the air chamber aluminum film are respectively provided with a guide column mounting hole for installing a guide column. The top of the guide column is fixedly mounted on an adapter pressure plate. The adapter pressure plate is mounted on the lower surface of the fixed base plate by bolts. The fixed base plate is connected to a movable cylinder for driving it to move up and down. When the fixed base plate drives the air chamber aluminum mold to move to the lowermost position under the drive of the movable cylinder, the lower edge of the air chamber aluminum mold abuts against a supporting platform provided on the peripheral edge of the lower part of the intercooler air chamber. The supporting platform can strengthen the strength of the intercooler air chamber while ensuring that it fits with the air chamber aluminum mold and ensures effective pressure transmission.

[0006] Preferably, the lower edge of the air chamber aluminum mold is concave upward and inward to form a load-bearing platform that cooperates with the supporting platform of the intercooler air chamber, thereby ensuring the effectiveness of the fit and preventing the intercooler air chamber from being scratched.

[0007] Preferably, a downward pressing stroke limit block is provided at each of the four corners of the lower surface of the air chamber aluminum mold, so that when the air chamber aluminum mold is pressed down to the lowest point of the stroke, the downward pressing stroke limit block presses against the pressing platform on which the intercooler air chamber and the main plate are placed, thereby ensuring that the downward pressing stroke of the air chamber aluminum mold is limited, preventing the intercooler air chamber from being crushed or the main plate from being deformed or the sealing gasket from being damaged.

[0008] Preferably, the fixed base plate is provided with limit pins for limiting the fixed base plate and the movable cylinder, thereby ensuring the positioning of the movable cylinder and the fixed base plate, reducing the cycle of each tooling change and reducing the debugging cost.

[0009] Preferably, the guide column is fixedly installed in the guide column installation hole by means of bolts, and different types of intercooler air chambers can be matched by replacing the guide columns of different heights.

[0010] Preferably, the reinforcing ribs of the intercooler air chamber do not exceed the outer contour size of the main plate, so as to avoid dimensional interference and reduce the risk of the intercooler air chamber being crushed.

[0011] Preferably, the height of the downward stroke limit block is calculated based on the compression amount of the sealing gasket installed on the main plate and the fitting tolerance of the parts, so as to avoid quality problems caused by too small or too large downward stroke.

[0012] Preferably, the length of the fixed base plate is greater than the width of the air chamber aluminum mold, ensuring that the force of the movable cylinder can be stably transmitted to the air chamber aluminum mold, avoiding shaking during operation and reducing the risk of interference with the intercooler air chamber.

[0013] A method for pressing down the intercooler air chamber and the main plate pressing tool, placing the main plate, the sealing gasket and the intercooler air chamber on the pressing platform in sequence, starting the movable cylinder, driving the air chamber aluminum mold to descend and cover the intercooler air chamber until the lower edge of the air chamber aluminum mold abuts against the supporting platform of the intercooler air chamber.

[0014] Compared with the prior art, the present invention has the following advantages:

[0015] 1. A support platform is added to the intercooler air chamber, which improves the overall strength of the intercooler air chamber, provides a good fulcrum for the pressing tooling, and ensures the stability of the pressing stroke;

[0016] 2. Ensure the uniformity of the compression of the entire gasket and improve the high-temperature durability of the intercooler;

[0017] 3. Use the downward stroke limit block to limit the downward stroke of the air chamber aluminum mold to prevent the intercooler air chamber from being crushed or the main plate from being deformed or the sealing gasket from being crushed;

[0018] 4. The load-bearing platform of the air chamber aluminum mold is only in contact with the supporting platform and is completely separated from the other parts of the intercooler air chamber, which increases the fit between the pressing tooling and the intercooler air chamber, ensures the stability of the pressing tooling, and greatly shortens the machine adjustment time.

DETAILED DESCRIPTION

[0029] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] like Figure 1 , Figure 3 and Figure 4 As shown, an intercooler air chamber and main plate pressing tooling includes a fixed bottom plate 1 and an air chamber aluminum mold 2, combined with Figure 2As shown, the air chamber aluminum mold 2 is a hollow structure. The four corners of the air chamber aluminum film 2 are each provided with a guide column mounting hole 4 for mounting a guide column 3. The top of the guide column 3 is fixedly mounted on a transfer plate 5. The transfer plate 5 is mounted on the lower surface of the fixed bottom plate 1 by bolts. The fixed bottom plate 1 is connected to a movable cylinder that drives it to move up and down. When the fixed bottom plate 1 drives the air chamber aluminum mold 2 to move to the lowest position under the drive of the movable cylinder, the fixed bottom plate 1 is combined with the air chamber aluminum mold 2 to move to the lowest position. Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, the lower edge of the air chamber aluminum mold 2 abuts against the support platform 7 provided on the lower peripheral edge of the intercooler air chamber 6.

[0031] In addition, the lower edge of the air chamber aluminum mold 2 is concave upward and inward to form a load-bearing platform 8 that cooperates with the supporting platform 7 of the intercooler air chamber 6, thereby ensuring the effectiveness of the fitting and preventing the intercooler air chamber 6 from being scratched.

[0032] At the same time, a downward stroke limit block 9 is provided at each of the four corners of the lower surface of the air chamber aluminum mold 2, so that when the air chamber aluminum mold 2 is pressed down to the bottom of the stroke, the downward stroke limit block 9 abuts against the intercooler air chamber 6, and the downward stroke of the air chamber aluminum mold 2 is limited, thereby preventing the intercooler air chamber 6 from being crushed or the main plate 11 from being deformed or the sealing gasket 12 from being crushed.

[0033] In this embodiment, the fixed base plate 1 is provided with a limit pin 10 for limiting the fixed base plate 1 and the movable cylinder, so as to ensure the positioning of the movable cylinder and the fixed base plate 1, reduce the period of each tool change, and reduce the debugging cost. The guide column 3 is fixedly installed in the guide column mounting hole 4 by bolts, and different types of intercooler air chambers 6 are matched by replacing guide columns 3 of different heights. The reinforcing ribs of the intercooler air chamber 6 do not exceed the outer contour size of the main plate 11, so as to avoid dimensional interference and reduce the risk of the intercooler air chamber 6 being crushed.

[0034] In this embodiment, the height of the downward stroke limit block 9 is calculated based on the compression amount of the sealing gasket 12 installed on the main plate 11 and the fitting tolerance of the parts to avoid quality problems caused by too small or too large downward stroke. The length of the fixed base plate 1 is greater than the width of the air chamber aluminum mold 2 to ensure that the force of the movable cylinder can be stably transmitted to the air chamber aluminum mold 2 to avoid shaking during operation and reduce the risk of interference with the intercooler air chamber 6.

[0035] When the intercooler air chamber and main plate pressing tooling of this embodiment is used, the main plate 11, the sealing gasket 12 and the intercooler air chamber 6 are placed on the pressing platform in sequence, and the movable cylinder is started to drive the air chamber aluminum mold 2 to descend and cover the intercooler air chamber 6 until the lower edge of the air chamber aluminum mold 2 abuts against the supporting platform 7 of the intercooler air chamber 6, and then the main plate engaging tooling can be operated to engage the main plate 11 on the intercooler air chamber 6. In this process, the pressing stroke limit block 9 limits the pressing stroke of the air chamber aluminum mold 2 to prevent the intercooler air chamber 6 from being crushed or the main plate 11 from being deformed or the sealing gasket 12 from being crushed.

[0036] The intercooler air chamber and main plate pressing tooling and pressing method of the present invention add a supporting platform 7 to the intercooler air chamber 6, thereby improving the overall strength of the intercooler air chamber 6, providing the pressing tooling with a good fulcrum and ensuring the stability of the pressing stroke; at the same time, ensuring the uniformity of the compression amount of the entire sealing gasket 12, improving the high-temperature durability of the intercooler; limiting the pressing stroke of the air chamber aluminum mold 2 through the pressing stroke limit block 9, preventing the intercooler air chamber 6 from being crushed or the main plate 11 from being deformed or the sealing gasket 12 from being crushed; in addition, the load-bearing platform 8 of the air chamber aluminum mold 2 is only in contact with the supporting platform 7 and is completely separated from other parts of the intercooler air chamber 6, thereby increasing the fit between the pressing tooling and the intercooler air chamber 6, ensuring the stability of the pressing tooling and greatly shortening the machine adjustment time.
