Furthermore, the terms "first" and "second" are used only for descriptive purposes and are not intended to have a special meaning.
The embodiment of the invention provides a method for manufacturing a gas storage beam, which comprises the following specific steps:
firstly, a blow molding opening 110 is formed in the beam body 100.
Specifically, the beam 100 is made of a metal material, and may be integrally cast in the prior art, and the process route is sand casting. The cast beam 100 has openings at both ends.
More specifically, the blow-molding opening 110 is opened at the middle position of the beam body 100, so that compressed air can be injected into the beam body 100 through the blow-molding opening 110 in a balanced manner from the center position, thereby facilitating the subsequent formation of the air reservoir 200.
Step two, the parison is placed in the beam body 100.
Specifically, the parison is made of a non-metal material, and specifically, a tubular plastic parison obtained by extruding or injection molding thermoplastic resin can be selected. The non-metal air cylinder 200 formed by blow molding of the non-metal parison has better sealing performance and elasticity, is not easy to break due to overlarge air pressure, and has stronger reliability.
And step three, closing the openings at the two ends of the beam body 100 by the plugging piece.
Specifically, the plugging member may be a rubber sealing plug in the prior art, and after the openings at the two ends of the beam body 100 are plugged by the rubber sealing plug, a closed blow space is formed inside the beam body 100, so as to perform a shaping function on the subsequent blow molding of the air cylinder 200.
And fourthly, blowing the parison through the blowing port 110 to form the air cylinder 200.
Specifically, the air cylinder 200 is expanded and blow-molded by using the inner wall of the beam body 100 as a shaped wall surface, and the outer wall of the air cylinder 200 abuts against the inner wall of the beam body 100 after molding, so as to form the beam body 100 with the air cylinder 200 inside, and obtain the frame beam body assembly with the air storage function.
Preferably, a pressure limiting valve is installed in the blowing port 110, and the pressure limiting valve is configured to control the pressure of the blowing air, so as to prevent the blowing pressure from being too high, thereby causing damage to the parison or rupture of the air cylinder 200.
And step five, the air outlet 120 and the air inlet 130 are opened on the air storage cylinder 200.
Specifically, the air outlet 120 and the air inlet 130 are arranged in parallel at the middle position of the air reservoir 200, openings are respectively arranged on the side wall of the beam body 100 corresponding to the positions of the air outlet and the air inlet, the air outlet 120 and the air inlet 130 are communicated with the outer space of the air reservoir 200 and the beam body 100, the air outlet 120 is used for subsequent connection with a brake unit, and the air inlet 130 is used for subsequent connection with an air pump.
And step six, plugging the blow molding opening 110.
Specifically, after the air cylinder 200 is blow-molded, the blow-molding opening 110 is sealed, and a metal sealing member with a rubber sealing ring may be selected to seal the blow-molding opening 110, so as to ensure the integrity of the beam body 100.
And seventhly, removing the plugging pieces at the openings at the two ends of the beam body 100.
Specifically, after the air cylinder 200 is formed by blow molding, the plugs at the openings at the two ends of the beam body 100 are removed. Because the beam body 100 does not play a role in gas storage, the beam body has no sealing requirement, and the weight of the beam body 100 can be effectively reduced by removing the blocking pieces at the two ends, so that the aim of light weight of the commercial vehicle frame is fulfilled.
Fig. 1 shows a schematic view of a gas storage beam structure provided in an embodiment of the present invention, and fig. 2 shows a schematic half-section view of a gas storage beam provided in an embodiment of the present invention. Referring to fig. 1 and 2, an embodiment of the present invention further provides a gas storage beam, which is manufactured by using the method for manufacturing the gas storage beam, and includes a beam body 100, a gas storage cylinder 200, a gas outlet 120, and a gas inlet 130.
Specifically, the air cylinder 200 is sleeved in the beam body 100, and the beam body 100 limits the internal air cylinder 200, so as to prevent the air cylinder 200 from being broken due to over-expansion in the air intake process. And the air cylinder 200 is independent from the beam body 100, thereby fundamentally avoiding the potential safety hazard of air leakage of the air cylinder when the beam body is deformed or broken.
More specifically, the beam body 100 is fixedly connected to a connection wing plate 300 at an end thereof, the connection wing plate 300 is provided with a plurality of mounting holes 310, and as shown in fig. 1, the connection wing plate 300 is configured to connect the beam body 100 and the frame rail. The connection flange 300 can increase the contact area between the beam 100 and the frame rail, and the beam 100 is fixed to the frame rail by the cooperation of the mounting members such as bolts and the mounting holes 310, thereby forming a frame assembly with a gas storage function.
More specifically, the air outlet 120 communicates with the brake unit and the air inlet 130 communicates with the air pump. High-pressure air in the air pump enters the air storage cylinder 200 from the air inlet 130 and is temporarily stored, and when the brake unit needs, the high-pressure air in the air storage cylinder 200 enters the brake unit from the air outlet 120, so that the vehicle brake is realized. The brake unit and the air pump are both provided with an air brake and an air supply pump in the prior art, and the working principle of the brake unit and the air supply pump is not described herein again.
It should be understood that the above-described embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. Numerous obvious variations, adaptations, and substitutions will occur to those skilled in the art without departing from the scope of the present invention. And are neither required nor exhaustive of all embodiments. Any modification, equivalent replacement, and improvement made within the spirit and principle of the present invention should be included in the protection scope of the claims of the present invention.
