Abstract

The invention relates to general engineering and can be used for aerosol lubrication of dies. The purpose of the invention is to simplify the design and expand the functionality of the device. When a signal is applied to the element 77 70 J9, the mentality YES triggers trigger 22, the signal from which is fed to the air distributor and ensures that the nozzle moves to the working position, connecting it to the oil dispenser. This triggers the valve of sequence 18, the signal from which is the origin of the lubrication time. After the end of the lubrication, the signal from the delay unit cocks the trigger 23, the signal from which, having passed through the element OR 19, resets the trigger 22 and returns the pneumatic cylinder rod to its original position. The signals from the trigger 23 and the limit switch, form the output element And a signal about the end of the lubrication circuit of the stamp. Sequence valve 17, BAN and OR elements 20, 21 provide emergency blocking with returning the rod to the initial position and emergency alarm. 1 il. 75 cl: o with; o ate

Description

The invention relates to general engineering and can be used for aerosol lubrication of dies.

The purpose of the invention is to simplify the design and expand the functionality of the device.

The drawing is a schematic diagram of the device.

The device consists of a two-sided nozzle 1 mounted on the rod 2 with the valve 3 of the pneumatic cylinder 4 with the coupling 5, the air distributor 6, the ejector oil sprayer 7 with the upper 8 and lower 9 chambers, two channels 10, 11 with a check valve 12 and an adjustable choke 13, ejector device. 14, the limit switch 15 and the control system in the form of a block 16, which contains two sequence valves 17, 18, three elements OR 19, 20, 21, two triggers 22, 23, BAN 24, elements YES 25, 26 , two adjustable pneumatic resistances 27, 28, normally closed The experienced valve 29 and the signal delay node 30, including the pneumorel 31, stub-wash 32 and adjustable pneumatic resistance 33.

The device works as follows.

Power is applied to the air distributor 6, the ejector oil distributor 7, the limit switch 15 and the pneumatic control unit 16. The rod 2 of the pneumatic cylinder 4 is in the extreme left position and closes the limit switch 15. As a result, a signal is received at the input of the normally closed valve 29 and the control chamber of the pneumorel 31 is in communication with the atmosphere. The signal at the input element YES 26 is missing.

With the arrival at the control input of the YES 26 element of the discrete signal "The unit begins the stamp lubrication cycle. The signal from the output element YES 26 enters the second input of the trigger 23 and the first input of the trigger 22. The signal from its output enters the control chamber of the air distributor 6, the nozzle 1 starts moving to the extreme right position. The limit switch 15 is released. At this position, the channel 3 of the choke 2 via the coupling 5 communicates the oil sprayer 7 with the nozzle 1. The pressure in the upper chamber 8 drops. The relay of the sequence 18 is activated, the signal “Unit from which is fed to the BANGE 24 element, to the second input of which from the trigger 22 after a period of time determined by the setting of throttles 27, the signal“ Unit ”also arrives. The signal from the relay of the sequence 18 passes to the node 30 of the delay, from which with a delay in time comes through the pneumatic resistance 28 to the element OR 21 and to the first input of the trigger 23. The signal "The unit from the output of the trigger 23 arrives at the input of the element 25 and passes through the element OR 19 to the second input trigger0

ra 22, dropping it. The movement of the pneumatic cylinder 2, the valve 2, begins. The channel 3 is separated from the coupling 5. The valve of the sequence 18 returns to its original position. The rod 2 in the leftmost position presses the limit switch 15, which opens the valve 29, together with the control chamber of the pneumorel 31 and the air capacity 32 with the atmosphere. The signal from the limit switch 15 also arrives at the second input of the element I 25, at the output of which the signal "Unit of the end of the lubrication cycle of the chipboard signal appears. The proposed device has a simpler design as compared with the known ones and possesses wide functional capabilities.
