Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of the automotive and new energy vehicle industries, and is used for manufacturing a radiator water chamber, and relates to a water pipe riveting tooling. Background Art
[0002] A new energy vehicle refers to a vehicle that uses unconventional vehicle fuel as a power source or uses conventional vehicle fuel and a new type of vehicle-mounted power device, and integrates advanced technologies in the aspects of power control and drive of the vehicle, forming a vehicle with advanced technical principles, new technologies and new structures. A battery cooler is a key component for the battery thermal management of a pure electric or hybrid vehicle. Its function is to introduce the refrigerant in the air-conditioning system, evaporate after throttling by an expansion valve, and absorb the heat of the coolant in the battery cooling circuit. In this process, the refrigerant takes away the heat of the coolant through heat exchange, playing a role in cooling the battery.
[0003] The basic structures of battery coolers are roughly the same, and are respectively composed of two coolant inlet and outlet pipes, two refrigerant inlet and outlet pipes, a heat exchanger main body and an external evaporator. The main body of the heat exchanger is composed of many plate heat exchange fins stacked up. The coolant and the refrigerant flow into the heat exchanger main body in a convection form. In the heat exchanger main body, the coolant and the refrigerant are separated by layers and form a sandwich structure with each other. During the convection process, heat is transferred from the coolant to the refrigerant to achieve heat exchange. The battery cooler includes a structure for connecting a cover plate and a water pipe. Currently, a riveting head structure is used to tightly connect the two. However, the existing riveting head structure cannot distribute the acting force of the press more to both sides, which is not convenient for the water pipe to be tightly combined with the cover plate after deformation. Therefore, a water pipe riveting tooling is needed to solve the above problems. Summary of the Utility Model
[0004] In order to solve the above problems, the utility model provides a water pipe riveting tooling, which includes a fixed top plate and mounting columns arranged around the fixed top plate. A lower pressing plate is mounted on the fixed top plate, and two riveting head structures are mounted on the lower pressing plate. The lower ends of the riveting head structures connect the cover plate and the water pipe in a riveting manner. A first inclined surface structure is provided near the cover plate. The first inclined surface structure extends to a straight surface structure, and the straight surface structure continues to extend to a second inclined surface structure. The inclination of the first inclined surface structure is greater than that of the second inclined surface structure.
[0005] A further improvement of the utility model lies in that the included angle between the two first inclined surface structures is 11°.
[0006] A further improvement of the utility model lies in that the included angle between the two second inclined surface structures is 30°.
[0007] A further improvement of the present utility model lies in that: R corners are provided on both sides of the second inclined plane structure near the bottom end, and the R corners are 84.5°. The R corners are provided to prevent the riveting head structure from cracking during the downward pressing process.
[0008] A further improvement of the present utility model lies in that: a support platform is installed below the water pipe, and a limiting groove structure is provided on the upper end surface of the support platform. The limiting groove structure can play a role in limiting the water pipe.
[0009] A further improvement of the present utility model lies in that: an anti-slip layer structure is provided on the end surface of the limiting groove structure, which can increase the friction force on the bottom of the water pipe to achieve the anti-slip effect.
[0010] A further improvement of the present utility model lies in that: the water pipe is clamped on the clamping position panel, and two through-hole structures are provided on the clamping position panel to facilitate the installation of the water pipe. The two through-hole structures can play a role in limiting.
[0011] A further improvement of the present utility model lies in that: a cover plate support platform is provided between the clamping position panel and the cover plate.
[0012] Beneficial effects:
[0013] The riveting head structure of the present utility model is provided with the first inclined plane structure, and thus a straight plane structure extends from the first inclined plane structure, and the straight plane structure continues to extend to form a second inclined plane structure. The inclination of the first inclined plane structure is greater than that of the second inclined plane structure. Such a structural setting can distribute more of the acting force of the press to both sides, facilitating the tight combination of the water pipe and the cover plate after deformation.
