Description

Cooling oil spraying device of high-speed press

Technical Field

The utility model relates to the technical field of high-speed presses, in particular to a cooling oil spraying device of a high-speed press.

Background

With the advent of industry 4.0, automation and continuous development of informatization, the application range of the motor is wider and wider, and the requirement on the motor is higher and higher. The thickness of the stator and the rotor of the motor iron core is gradually reduced from 0.5mm to 0.35mm, 0.25mm and even 0.2mm. The iron core stator and the iron core rotor are used as core components of the motor, and the quality of the motor can be directly influenced by the accuracy of the iron core stator and the iron core rotor. The thinner the core material, the smaller the gap between the concave and convex molds in the mold must be, and the higher the corresponding precision requirement on the press machine is. Meanwhile, in order to save materials and improve efficiency, the shapes of the stator and rotor molds must be longer, so that the table surface of a high-speed punch using the molds must be longer.

The high-speed press is used as a professional machine in the iron core stator and rotor stamping industry, and the common high-speed press can not meet the production requirements of the products. Currently, high-speed presses are continuously moving toward higher speed and longer table tops, and have been moving from early four-point spindle supports, dual-link force applying mechanisms to six/eight-point spindle supports, and three-link/four-link force applying mechanisms. The higher the speed, the greater the heat energy generated inside the press; the longer the mesa, the more the main shaft friction pair that is used for supporting and the crank friction pair that is used for application of force, connecting rod friction pair quantity also are, and the corresponding heat energy that produces is also bigger. And the larger the heat energy, the larger the thermal deformation generated by the press. Thermal deformation errors are a major factor affecting the accuracy of high speed presses, particularly on the parallelism of the upper and lower tables.

Description of the embodiments

The cooling oil spraying device of the high-speed press comprises a high-speed press body, an oil supply mechanism and a cooling mechanism;

the high-speed press main body comprises a cross beam 1, a sliding block 5, a workbench plate 6, left and right stand columns 9 and a base 10, wherein an oil tank is arranged in the cross beam 1, an oil tank is arranged in the base 10, and oil supply pipelines are arranged in the left and right stand columns 9;

the oil supply mechanism comprises a lubricating oil pump 12, a pressure filter 11, a main shaft friction pair 2, a crank friction pair 3, a connecting rod friction pair 4, a ball head friction pair 7 and a guide pillar friction pair 8;

the cooling mechanism comprises a stop valve 13, a filter 14 and a lubricating system oil cooler 15;

the lubricating oil pump 12 extracts lubricating oil in an oil tank of the base 10, and after the lubricating oil is filtered by the pressure filter 11, the lubricating oil is supplied to the main shaft friction pair 2, the crank friction pair 3 and the connecting rod friction pair 4 and is converged in an oil pool of the cross beam 1; one part of lubricating oil in the oil pool flows back into an oil tank of the base 10 through oil supply pipelines in the left and right upright posts 9, and the other part flows to the sliding block 5 for lubricating the ball head friction pair 7 and the guide pillar friction pair 8 and flows back into the oil tank of the base 10 through the oil supply pipelines in the left and right upright posts 9;

the cooling oil spraying device is arranged in the beam 1 and comprises a plurality of nozzles 16, after the lubricating oil in the oil tank of the base 10 is cooled by the lubricating system oil cooler 15, part of the lubricating oil flows back into the oil tank of the base 10, and the other part of lubricating oil is supplied into the nozzles 16 to spray the inside of the beam 1.

In the cold state, the inside of the press is free from any relative movement, so that no heat energy is generated, the parallelism of the upper table top and the lower table top of the press is not influenced, and the parallelism of the upper table top, the lower table top, the middle table top and the right table top are considered to be approximately equal.

In the heat engine state, a large amount of heat energy is generated inside the cross beam 1 and the sliding block 5 due to the high-speed relative movement of each friction pair of the press. The metal part expands when heated, the larger the appearance and the higher the temperature, and the larger the corresponding expansion amount. Since the slide 5 is restricted by the positions of the left and right columns 9 in the left and right direction, and cannot be displaced in this direction, deformation and change to an arch shape can only be generated in the vertical direction, and at this time, the parallelism of the upper and lower tables of the press machine is deviated, and the longer the length of the slide 5 and the table plate 6 in the left and right direction is, the larger the deviation amount is generated.

The temperature of lubricating oil stored in an oil pool inside the cross beam 1 is high due to a large amount of heat energy generated by the relative movement of the six groups of main shaft friction pairs 2, the three groups of crank friction pairs 3 and the three groups of connecting rod friction pairs 4 in the cross beam 1, and the part of hot oil passes through the sliding block 5 and can also influence the sliding block 5. After the cold lubricating oil directly sprays the cross beam 1, part of heat generated by relative motion of the main shaft friction pair 2, the crank friction pair 3 and the connecting rod friction pair 4 is neutralized, and meanwhile, after the cold lubricating oil is mixed with hot oil, the whole oil temperature in the cross beam 1 is reduced, and the generation of thermal expansion of the cross beam 1 and the sliding block 5 is relieved, so that deviation generated by parallelism of an upper table top and a lower table top in the state of a cold machine and a heat machine is compensated to a certain extent.

The utility model aims to solve the problems that the parallelism of an upper table top and a lower table top is changed and a certain deviation is generated due to the thermal deformation error when a press is in a cold state and a hot state, the precision of a product formed by blanking of the press is influenced, and a cooling oil spraying device is added to compensate the parallelism of the upper table top and the lower table top on the basis of the original circulating oil lubrication system of a high-speed press.
