Description

Technical Field

[0001] The utility model belongs to the technical field of heating devices, and particularly relates to a heating device for the inner cavity of a vehicle body. Background Art

[0002] Automobile cavity waxing is a standard anti-corrosion process. Before waxing, it is necessary to ensure that the inner cavity of the vehicle body reaches a stable process temperature to ensure that the wax film is completely covered and has a uniform thickness, achieving the best anti-corrosion performance. The existing technology generally uses a profiling air nozzle to heat the vehicle body in a preheating furnace, and heats from the outer surface of the vehicle body through air convection and then conducts to the inner cavity of the vehicle body; however, due to the multi-layer plates and non-metallic materials of the vehicle body, the heating effect inside the vehicle body cavity is insufficient, and the temperature gradient inside the vehicle body cavity is relatively large. Content of the Utility Model

[0003] Aiming at the problems of low heating efficiency and uneven distribution of the vehicle body temperature field in the existing technology, the utility model provides a heating device for the inner cavity of a vehicle body. This heating device can be directly applied to the existing waxing production line, which can improve the temperature gradient inside the vehicle body cavity while improving the utilization efficiency of wax in the waxing process, reducing energy consumption, and reducing wax liquid pollution to the vehicle body.

[0004] The utility model is realized through the following technical solutions:

[0005] A heating device for the inner cavity of a vehicle body is installed directly below the vehicle body heating position in a preheating furnace, and includes a booster fan 1, a mixing box 2, a vertical adjustment cylinder 5, at least one horizontal adjustment cylinder, and at least one nozzle slidably connected to a slide rail 6; the booster fan 1 is connected to the mixing box 2, the outlet of the mixing box 2 is connected to the nozzle, the horizontal adjustment cylinder is connected to the nozzle and is used to drive the nozzle to move in the horizontal direction; the vertical adjustment cylinder 5 is fixedly connected to the slide rail 6 and is used to drive the nozzle to move in the vertical direction.

[0006] Further, the outlet of the mixing box 2 is connected to the nozzle through a hose 4.

[0007] Further, the horizontal adjustment cylinder is connected to the slide rail 6 through a telescopic rod 9 and a movable connecting piece 10, and the nozzle is fixed on the movable connecting piece 10.

[0008] Further, the horizontal adjustment cylinder includes a first horizontal adjustment cylinder 3 and a second horizontal adjustment cylinder 8.

[0009] Further, the vertical adjustment cylinder 5 is fixed on the slide rail 6 through a fixed connecting piece 7, and the vertical adjustment cylinder 5 drives the slide rail 6 to move in the vertical direction, thereby driving the nozzle to move in the vertical direction.

[0010] Further, the inlet of the booster fan 1 is connected to the air box of the preheating furnace, and no additional heating device is required.

[0011] Furthermore, the whole body inner cavity heating device is fixed on the bottom plate of the preheating furnace through a base.

[0012] Furthermore, 6 hot air outlets are arranged on the air mixing box 2, all of which are connected to the nozzles; the number of nozzles can be adjusted according to needs, and each nozzle requires a horizontal adjustment cylinder to adjust the horizontal position.

[0013] Compared with the prior art, the advantages of the present utility model are as follows:

[0014] 1. For a body inner cavity heating device of the present utility model, the heat source for heating the body inner cavity comes from the heat source of the preheating furnace itself, and the hot air after heating the body is discharged back into the preheating furnace. Only a small-power booster fan is needed to greatly improve the temperature distribution in the body inner cavity.

[0015] 2. It can make the temperature in the body inner cavity meet the process requirements and be uniform, reduce the better fluidity of the liquid wax, avoid the solidification of the wax, make the wax film in the air thinner, more complete and uniform, and reduce the consumption of wax.

[0016] 3. All actions of this device can be completed by using small cylinders. The overall device has a small volume and can be integrated under the grid plate of the preheating furnace. The used air source can also be directly led out from the nearby wax filling device. Almost no modification is required for the existing preheating furnace. At the same time, each part in the structure can be replaced according to the actual situation on site, and it has excellent versatility. Description of the Drawings
