Abstract

The invention relates to the processing of metals by pressure and may be used in the forging-forging industry for applying coolant to a tool during hot ptamping. The goal is to improve the quality of lubrication of the tool surface by increasing the accuracy of lubricant dosing and improving the service conditions of the device for periodic lubrication of dies. The device contains a lubricant tank 1 in which a dispenser 3 with a float 8 is placed, ensuring that the dispenser 3 is in a constant position relative to the surface of the lubricant. The cavity of the dispenser 3 in the initial position is connected to the atmosphere by the pipeline 5 and the hoses 16, 18 through the mixer 12 and the nozzles 13 and is filled with lubricant through the pipe 4, the amount of which depends on the position of the ends of the pipe 4 and the pipe 5 in the dispenser. When the valve 14 is turned on, air enters the dispenser 3, displaces the lubricant from it into the mixer 12 and nozzles 13 and through the reducing valve 7 through the pipe 4 and P1lang 19 under the grid 2 for mixing the lubricant in the tank 1. 1 h. item f-ly, 1 ill. 1211 П V / Л; о со; о О) 19

Description

The invention relates to the processing of metals by pressure and can be used in forging and stamping production for applying coolant to a tool during hot stamping.

The purpose of the invention is to improve the quality of lubrication of the tool surface by increasing the accuracy of lubricant dosing and improving the conditions of the lubricant of the device for periodic lubrication of ujTaMnoB.

The drawing shows a device for periodic lubrication of the stamps, a general view, a section.

A device for periodical lubrication of dies comprises a tank 1, in which a grid 2 is dispensed, a dispenser 3 with a lubricant supply pipe 4 and air supply and lubrication pipelines 5 and 6, a reducing valve 7, a float 8, valves 9. And). 11, a mixer 12. nozzles 13, an electric pump: not a single valve 14, a pipeline 15 for supplying compressed air, connecting flexible nj. iaiirn 16-19 and bracket 20.

Attachment (IS) of the district is as follows.

In the initial field (the J2 electromagnetic valve 14 is turned off, the valves 9. 10, 11 are open and the dispenser cavity. I through r |) at the lines 5, 15 and hose 18, the mixture of gel 1 and nozzle 13 communicates with aTMoc {| iopoii. The dispenser 3 is mounted on the pas (noodle nozzle i 8 and is immersed in grease, according to ni.iaiiry 19 and the nozzle 4 is in the cavity of the dispenser 3. lift the reduction valve 7, made from a material with a specific weight of water, for example, a polyurethane plat. When the lubricant level in the dispenser 3 reaches the torn of the nozzle 4 of the pipe 5, it is lubricated and lubricated B iio; iocTb of the dispenser 3 nN Krats1a (. m. s. since an air block is formed over the IKH surface).

When the 1Ch1It1101) valve 14 is turned on, the air 14 through the coarse pipes 5, 15 and P1lang 16 enters the dispenser 3 and dismounts the lubricant into the mix, 1 12,; It is mixed with air coming from pipe 15 through a 1-hose 10. From mixer 12, lubricant is in the aerosol state through hose 18 to the nozzles 13 At the same time under the action of air coming into pipeline 5, reducing valve 7 pressed to the end of the pipe 4 and closes the cavity, with this air through a regular opening in the reduction valve 7 flows through the pipe 4, the hose 19 under the grid 2 and, evenly distributed, you

walks on the surface of the lubricant, carried out its mixing. Upon completion of the lubricant supply to the P1tamp, the valve 14 is turned off. Then the cycle of operation is repeated.

During prolonged interruptions and operation, the constant air supply under the grid 2 through pipelines through the dispenser 3 is dried, with Kg, the electromagnetic K, ia-pan 14 is turned on, and the valve 11 is closed.

The amount of lubricant supplied to the stamp is re-arranged by changing the position of the ends of the nozzle 4 and the pipeline 5 in the cavity of the dispenser 3. For convenience of adjustment, they are connected between the assembly (L) and Co6oii 20.

The valves 9 and I) regulate the flow rate of the air supplied to the dispenser 3 and blend 12. Reducing valve 7 is used to provide 6i) icT |) oro filling of the part of the dispenser 3 with lubricant and supply of optimum air volume n (Jcegky 2 for re-lubrication of the lubricant in the tank.
