Description

Technical Field

[0001] The utility model belongs to the field of wheel hub casting, and in particular relates to an auxiliary heating device for a spinning mold. Background Art

[0002] At present, in wheel hub casting, the wheel hub blank needs to be heated to a certain temperature in a furnace, and then the wheel hub blank is placed in a mold and formed by spinning the wheel and mold. The wheel hub can be made without heating the mold, but the wheel hub scrap will increase in the early stage of processing. Heating the mold in advance can effectively solve the wheel hub scrap caused by low mold temperature in the early stage. In the current heating device structure, the igniter and the flamethrower are heated separately, and the flame detector hole is placed above the flamethrower. Due to the harsh internal environment, a release agent is required in the mold casting. There are many aluminum chips in the water vapor and spinning process, and the igniter has a small diameter, which is prone to orifice clogging. After a period of use, problems such as poor ignition, slow temperature rise, and the inability of the flame detector to detect occur. Summary of the Invention

[0003] In view of the above technical problems, the utility model provides a spinning mold auxiliary heating device with simple structure, stable operation, low cost and very convenient installation.

[0004] In order to achieve the above-mentioned purpose, the technical solution adopted by the present invention to solve its technical problem is: a spinning mold auxiliary heating device, including a main air intake pipe 2, a pressure reducing valve 1 and an air intake pressure gauge 3 arranged on the main air intake pipe 2.

[0005] After the air inlet pressure gauge 3 , two or more first metal hoses 6 are connected. The first metal hoses 6 are provided with a solenoid valve 4 and a first flow regulating valve 5 connected in sequence. A burner 7 is provided at the end of the first metal hoses 6 .

[0006] The combustion-supporting air blower 10 is further included. The combustion-supporting air blower 10 is connected to the burner 7 through a second metal hose 9 so as to provide the burner 7 with air or other gas for combustion support.

[0007] The burner 7 includes a shell with an opening, and an igniter, a flamethrower, and a flame detector are arranged inside the shell; the opening angle of the burner 7 is lower than the horizontal angle, and when the release agent liquid enters the burner 7 during operation, it can flow out by itself to prevent the ignition detector from getting wet and causing poor ignition. Since the igniter and flamethrower of the burner are integrated, the diameter is increased, and the flame detector hole is integrated inside the burner, the entire system can realize automatic mold heating, effectively reducing the problems of failure to ignite and flame detection during operation due to the small diameter of the igniter, increasing the on-site heating temperature and shortening the heating time, thereby improving production efficiency.

[0008] Furthermore, an air inlet pressure gauge 11 is provided at the air outlet of the combustion-supporting blower 10, and a second flow regulating valve 8 is provided on the second metal hose 9. The air inlet pressure gauge 11 and the second flow regulating valve 8 can facilitate the control of the air inlet volume, so that the burner combustion is stable and the temperature control is accurate.

[0009] Furthermore, the burner 7 is tilted downward at an angle of 0-30 degrees.

[0010] Furthermore, the burner 7 is provided with an air inlet connected to the first metal hose 6 and an air inlet connected to the second metal hose 9; the air inlet is arranged closer to the opening of the shell than the air inlet. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] Figure 1 This is a structural schematic diagram of a spinning mold auxiliary heating device according to an embodiment of the present utility model. DETAILED DESCRIPTION

[0012] In order to facilitate understanding by those skilled in the art, the present invention is further described below with reference to the embodiments and drawings.

[0013] A spinning die auxiliary heating device according to this embodiment, such as Figure 1 As shown, it includes a main air intake pipe 2, a pressure reducing valve 1 and an air intake pressure gauge 3 arranged on the main air intake pipe 2.

[0014] After the air inlet pressure gauge 3, two or more first metal hoses 6 are connected. The first metal hoses 6 are provided with a solenoid valve 4 and a first flow control valve 5 connected in sequence. A burner 7 is provided at the end of the first metal hose 6. A combustion-supporting blower 10 is also included. The combustion-supporting blower 10 is connected to the burner 7 via a second metal hose 9, thereby providing the burner 7 with air or other gas for combustion. An air inlet pressure gauge 11 is also provided at the air outlet of the combustion-supporting blower 10, and a second flow control valve 8 is provided on the second metal hose 9. The burner 7 is provided with an air inlet connected to the first metal hose 6 and an air inlet connected to the second metal hose 9; the air inlet is arranged closer to the opening of the shell relative to the air inlet.

[0015] The burner 7 includes a shell with an opening, and an igniter, a flamethrower, and a flame detector are arranged inside the shell; the opening angle of the burner 7 is lower than the horizontal angle, and in this embodiment, the downward tilt angle is 5 degrees. When the release agent liquid enters the burner 7 during operation, it can flow out by itself to prevent the ignition detector from getting wet and causing poor ignition. Since the igniter and flamethrower of the burner are integrated, the diameter is increased, and the flame detector hole is integrated inside the burner, the entire system can realize automatic mold heating, effectively reducing the problems of failure to ignite during operation and failure to detect flames due to the small diameter of the igniter, increasing the on-site heating temperature and shortening the heating time, thereby improving production efficiency.
