Problems solved by technology

[0002] Step drill, also known as step drill or pagoda drill, is mainly used for drilling thin steel plates within 3mm. One drill bit can replace multiple drill bits. Holes with different diameters can be processed according to needs, and large holes can be processed at one time. There is no need to replace the drill bit and make positioning holes, etc. Most of the existing cooling devices for step drilling ...

The cooling table 2 is arranged in the cooling device casing 1 and is arranged in the cooling device casing 1. At the bottom of the cooling platform 2 is provided with an oil reservoir 21, the oil reservoir 21 is filled with cooling oil, the PLC controller 3 is arranged on the cooling device housing 1, the cooling device housing 1 There are electric retractable doors 11 on both sides, the electric retractable door 11 is arranged in the middle of the two sides of the cooling device housing 1, the electric retractable door 11 on the left is the feed end of the cooling device housing 1, and the right The electric telescopic door 11 is the discharging end of the cooling device housing 1. The cooling device housing 1 is also provided with a lifting mechanism 4, a telescoping mechanism 5 and an oil removal mechanism 6. The lifting mechanism 4 is installed in the oil reservoir 21 Inside, the telescopic mechanism 5 is installed behind the cooling platform 2, the oil removal mechanism 6 is installed directly above the cooling platform 2, and the electric telescopic door 11 is connected to the PLC controller 3.
[0024] Further, the lifting mechanism 4 includes a placing table 41 for placing products to be cooled and a lifting motor 42. The placing table 41 is arranged in the middle of the oil reservoir 21, and the lifting motor 42 is arranged in the oil reservoir 21. Below, the lifting rod of the lifting motor 42 passes through the oil reservoir 21 and is fixedly connected to the bottom of the placing table 41, and the lifting motor 42 is connected to the PLC controller 3. ;
[0025] Further, a sealing block 43 is provided at the connection between the lifting rod of the lifting motor 42 and the bottom of the oil storage tank 21, and the sealing block 43 wraps the lifting rod in a ring shape, and the sealing block 43 is wrapped in the part where the lifting rod does not lift. Above, the outer surface of the sealing block 43 is fixedly connected to the bottom of the oil reservoir 21, and a plurality of sealing rings 44 are provided at the connection between the inner wall of the sealing block 43 and the lifting rod.
[0026] Further, the oil removal mechanism 6 includes a fixed base 61, a motor 62, and a mechanical arm 63. The fixed base 61 is installed directly above the cooling table 2, the motor 62 is fixedly installed below the fixed base 61, and the mechanical arm 63 is arranged below the motor 62, and the upper end of the mechanical arm 63 is connected to the output end of the motor 62, and the motor 62 is connected to the PLC controller 3.
[0027] Further, an air nozzle 64 for degreasing is provided on the other end of the mechanical arm 63.
[0028] Further, the telescopic mechanism 5 includes a telescopic motor 51, a telescopic rod 52, and a degreasing cover 53 to prevent the cooling oil from splashing during degreasing. The telescopic motor 51 is arranged behind the cooling platform 2 through a support plate 54 and a support frame 55, The two telescopic rods 52 are symmetrically arranged in front of the telescopic motor 51, and one end of the two telescopic rods 52 is connected with the output end of the telescopic motor 51, the oil removal cover 53 is arranged between the two telescopic rods 52, and The other end of each telescopic rod 52 is fixedly connected to both sides of the oil removal cover 53, and the telescopic motor 51 is connected to the PLC controller 3.
