Description

Technical Field

[0001] The invention relates to the technical field of automobile cooling pipe production, in particular to an intercooler pipe with a reinforcement sheet and a production process thereof. Background Art

[0002] With the development and progress of society, there are more and more cars. Heat dissipation is a problem that must be solved in the process of automobile production. Among them, engine intake heat dissipation is a link that needs to be solved. The function of the intercooler is to reduce the intake temperature of the engine. Intercoolers are generally only seen in cars with superchargers installed, because intercoolers are actually accessories for turbocharging. Their function is to reduce the temperature of high-temperature air after supercharging, reduce the heat load of the engine, increase the intake volume, and thus increase the power of the engine. For supercharged engines, intercoolers are important components of the supercharging system. Whether it is a supercharged engine or a turbocharged engine, an intercooler needs to be installed between the supercharger and the intake manifold. After the intercooler is installed and used, due to the high pressure at both ends, the two ends of the intercooler are easily squeezed and damaged by stamping, resulting in the intercooler being easily damaged and requiring repair or replacement, which increases the cost of automobile maintenance and manpower and material resources. The intercooler is assembled from the intercooler heat pipe, and the firmness of the intercooler mainly depends on the firmness of the intercooler heat pipe. The existing intercooler tubes have also been improved by adding reinforcing plates at both ends, but the reinforcing plates cannot be fully inserted when adding the reinforcing plates, resulting in large wind resistance of the produced intercooler and high material consumption. Therefore, it is necessary to find a process for intercooler heat dissipation tubes that can solve the above problems. Summary of the invention

[0003] The purpose of the present invention is to provide a production process for an intercooler tube with a reinforcement plate. The intercooler tube prepared by the production process has reinforcement plates added to both ends to increase the strength of the entire heat dissipation tube and the reinforcement plates can be fully inserted into the heat dissipation tube to reduce wind resistance. The production process is simple and does not require complex operations such as welding. Direct clamping saves energy, thereby solving the problems raised by the above-mentioned background technology.

[0004] In order to achieve the above object, the present invention adopts the following technical solutions:

[0005] A production process for an intercooler pipe with a reinforcement sheet comprises the following steps:

[0008] (3) Take out the pressed tube body and check whether it is pressed tightly, then turn the tube upside down and repeat steps (1) and (2);

[0009] (4) After the reinforcing plates are pressed tightly on the upper and lower sides of one end of the tube body, the direction of the tube body is changed and steps (1), (2) and (3) are repeated on the other end of the tube body. After checking that all the reinforcing plates are fixed, the fins are inserted into the tube body to obtain the finished intercooler tube.

[0014] Furthermore, the auxiliary fixing device is fixed in the middle of the base in an L-shape, and the horizontal portion of the auxiliary fixing device is in the same height as the lower surface of the mold.

[0015] Furthermore, the former is a square fixing member, and the four sides of the former are rounded.

[0016] Furthermore, the lower surface of the fixed punch is provided with an open downward U-shaped groove adapted to the upper surface of the mold.

[0017] According to the intercooler pipe with a reinforcement sheet disclosed in the present invention, the technical effects are as follows:

[0018] 1. The present invention can reduce wind resistance by at least 5% by directly inserting reinforcement sheets on the inner sides of both ends of the outer tube body, thus solving the problem that the reinforcement frame of the existing intercooler heat dissipation pipe protrudes outside the outer tube body to generate large wind resistance;
