[0027] In order to enable those skilled in the art of the present technology to better understand the technical solution of the present invention, the following will describe its detailed implementation manners in conjunction with the accompanying drawings:

[0028] Please refer to Figure 2 、 Figure 3 、 Figure 4 and Figure 5 and Figure 6 The best embodiment of the present invention, a coil oil spraying device, includes a frame 1, a touch control screen 2, an upper shield 3, a lower shield 4, two solenoid valves 5 and two groups of high-pressure nozzles 6.

[0029] The frame 1 includes a base 11, a lower column 12, an upper column 13 and an electric jack 14. The bottom end of the base 11 is fixed to the ground through a fixing bolt 16. A lower column mounting hole is provided on the base 11. The lower part of the lower column 13 is rotatably arranged in the lower column mounting hole through a bearing 15. An electric jack mounting hole is provided at the top end of the lower column 12. The electric jack 14 is arranged in the electric jack mounting hole, and the output end of the electric jack 14 is connected to the bottom end of the upper column 13. When the lower column 13 rotates in the lower column mounting hole, it drives the electric jack 14 and the upper column 13 to rotate synchronously. The electric jack 14 can drive the upper column 13 to move up and down.

[0030] An electric control box 10 is arranged on one side of the lower column 12, and the touch control screen 2 is arranged in the electric control box 10.

[0031] The upper shield 3 and the lower shield 4 are oppositely arranged one above the other on the upper upright column 13. Preferably, at one end of both the upper shield 3 and the lower shield 4, there are vertically penetrating column mounting holes 31. The top end of the upper upright column 13 sequentially passes through the column mounting holes 31 on the lower shield 4 and the upper shield 3. Inside the upper shield 3 and the lower shield 4, there is respectively a control gas delivery pipeline 50. Two solenoid valves 5 are correspondingly arranged inside the upper shield 3 and the lower shield 4, and each solenoid valve 5 is connected to the inlet end of the control gas delivery pipeline 50 inside the corresponding shield. The two solenoid valves 5 are respectively in communication with the touch control screen 2.

[0032] Two groups of high-pressure nozzles 6 are correspondingly arranged inside the upper shield 3 and the lower shield 4. Each high-pressure nozzle 6 uses an ST-6 type high atomization professional automatic nozzle, which has three input ports. One input port is for high-pressure air input, another input port is for stretching oil input, and the last input port is for control gas input. And the control gas input port of each high-pressure nozzle 6 is respectively connected to the control gas delivery pipeline 50 inside the corresponding shield.

[0033] At the four corners of the bottom end of the upper shield 3 and the four corners of the top end of the lower shield 4, there are respectively rollers 7. The rollers 7 are used to guide the coil sheet on the coil uncoiler, so that the coil sheet is always kept in the middle of the two groups of high-pressure nozzles 6. The upper shield and the lower shield can concentrate the oil mist sprayed by the high-pressure nozzles, prevent it from spraying outside, and can also recycle the excess grease through the shield.

[0034] On the touch control screen 2, there are a start / stop button 21, an oil spraying times setting button 22, and an interval time setting button 23. The touch control screen 2 controls the spraying work of the corresponding high-pressure nozzles 6 by controlling the two solenoid valves 5 according to the set oil spraying times and interval time. The solenoid valve 5 is externally connected to a control gas input device, and the solenoid valve 5 controls the quick spraying or quick closing of the corresponding high-pressure nozzle by controlling the on / off of the control gas in the control gas delivery pipeline 50.

[0036] The solenoid valve 5 adopts a two-position three-way small direct-acting solenoid valve. Compared with a two-position two-way valve, the two-position three-way small direct-acting solenoid valve closes more thoroughly and the switching is clearer.

[0037] Please refer to again Figure 6, the coil oil spraying device of the present invention is arranged between the coil uncoiler 100 and the flattening machine 300. The coil sheet 101 of the coil uncoiler 100 is led between two groups of high-pressure nozzles 6 through the rollers 7. The frame 1 adopts the form of a fixed base combined with a rotating column, and can rotate at different angles when in use or not in use. The electric ejector rod installed inside the lower column can lift or lower the upper column and the components such as the shield and high-pressure nozzles thereon to cooperate with the input position of the coil sheet 101 of the coil uncoiler 100.

[0038] When the coil oil spraying device of the present invention is in use, the touch control screen 2 communicates with the press. Each time the punch of the press stamping once, a pulse signal is sent to the touch control screen 2 through the cam 401, and the touch control screen 2 identifies the work of the press according to this pulse signal. The high-pressure air input port of each high-pressure nozzle 6 is externally connected to high-pressure gas, and the stretching oil input port is externally connected to a stretching oil input device. The number of oil spraying times and the interval time are set on the touch control screen 2. The touch control screen 2 controls the spraying work of the corresponding high-pressure nozzles 6 by controlling two solenoid valves 5 according to the set number of oil spraying times and the interval time.
