Description

Technical Field

[0001] The utility model belongs to the field of heat insulation cover oil spraying, and in particular relates to a heat insulation cover oil spraying device. Background Art

[0002] The muffler is a key component installed in the exhaust system of a car. Its main function is to reduce the noise and vibration generated by the exhaust system. When the car engine is running, the exhaust gas will enter the exhaust system in a high temperature and high pressure state. The noise and vibration in it will be transmitted to the surrounding of the vehicle through the exhaust pipe, causing noise pollution and discomfort.

[0003] Inside the muffler, there is a heat shield, which is formed by continuous die stamping. Before stamping, a layer of oil needs to be sprayed on the upper and lower surfaces of the heat shield so that the heat shield can provide lubrication during stamping, reduce friction between metal materials, and thus reduce wear and heat generation during stamping, which helps to extend the life of the mold and improve production efficiency. However, when spraying oil, the oil mist generated by the nozzle will dissipate in the air, causing environmental pollution in the workshop. Utility Model Content

[0031] The process of the utility model when in use is as follows: first, the unpunched heat insulation cover sheet metal is grabbed by a manipulator, and then it is placed into the heat insulation cover 2 through the opening 4 on the heat insulation cover 2. Since the heat insulation cover 2 has a grid plate 3, the sheet metal can be supported by the grid plate 3. Then the manipulator withdraws, and the lifting assembly is started, so that the lifting door 7 begins to descend. When the lifting door 7 descends, the opening 4 will be sealed. At this time, the oil nozzle 8 in the heat insulation cover 2 is started, and the top oil nozzle 8 and the bottom oil nozzle 8 begin to spray oil mist, so that both sides of the sheet metal are sprayed with oil. At this time, the heat insulation cover 2 will be full of oil mist, and the oil mist separator 6 starts to absorb oil, and the oil mist in the heat insulation cover 2 is sucked into the oil mist separator 6 for treatment, and finally clean air is discharged, wherein the oil mist separator 6 can adopt a separator of the brand Shangpin Environmental Protection and the model SP-75. After the sheet metal is sprayed with oil, the oil on it will drip to the bottom of the heat shield 2. At the same time, the oil not adsorbed by the oil mist separator 6 will also be deposited at the bottom of the heat shield 2, and finally discharged from the oil drain pipe 5 at the bottom of the heat shield 2. After the sheet metal is sprayed, the lifting door 7 is opened after an interval of 10-20 seconds, and the robot grabs the sheet metal into the mold for stamping.

Specifically, the utility model drives the lifting door 7 to move by the power component, wherein the power component specifically adopts a linear guide rail 12, and the moving block on the linear guide rail 12 drives the lifting door 7 to move up and down during the lifting and down. In order to prevent the lifting door 7 from deflecting during the lifting and down, a lifting slot 10 is provided in the heat shield 2, and the lifting door 7 is lifted and lowered in the lifting slot 10. In addition, the power component is fixed to the heat shield 2 by a reinforcing back plate 13, and the reinforcing back plate 13 is a vertical plate, and an inclined reinforcing rib 16 is fixed on the back of the vertical plate.
