Abstract
The invention relates to a self-lubrication device for a precise four-column cutting machine. The device comprises a valve body, a valve core and a compression spring, wherein one end of the valve body is connected with an oil inlet hole of a hydraulic system, and the other end of the valve body is connected with a lubrication pipeline; one end of the valve core is matched with the valve body in a sliding way; the other end of the valve core abuts against a hydraulic oil inlet; the compression spring is arranged between the valve body and the valve core; hydraulic oil acts on the valve core, so that the valve core can slide in the valve body; the size of the hydraulic oil inlet is automatically adjusted along with the change of the pressure of the system; therefore, a guide column can be fully lubricated, and the lubrication pipeline is prevented from being damaged when the pressure of the system is overhigh.
Description
Technical field
The present invention relates to the guillotine industry, especially the automatic lubricator of accurate four-column guillotine.
Background technique
Guillotine is primarily aimed at flexible sheet or the web-like material carries out processing such as severing, impression, punching, and wherein the use of the guillotine of accurate four-column pattern is the most general, during work; Four directional posts of accurate four-column guillotine must obtain lubricated fully, otherwise the working life that will reduce guillotine greatly, therefore present accurate four-column guillotine all has automatic lubricator; Principle is to utilize the hydraulic system of machine itself to give four directional post fuel feeding, and implementation is varied, as directly shunting fuel feeding from filler opening; This mode high lubricating effect, but to prevent the too high damage lubricating pipe of oil pressure and influence system works pressure also have lubricating pipe is connected on the oil return circuit of system; This mode is safer, but low fuel pressure, lubrication effect is undesirable sometimes; Be connected in addition on the oil cylinder cavity of resorption oil circuit, this mode oil pressure is moderate, and is lubricated reliable; But can influence the sealing of oil cylinder cavity of resorption, the phenomenon that head falls takes place easily.
To above-mentioned situation, manufacturing firm need take appropriate measures when using different lubricating systems, like filler opening shunting fuel system the step-down throttling arrangement must be arranged; Method commonly used now is the orifice restriction method, that is to say to let the pressure oil of system's filler opening supply with lubricating pipe through a very little hole, because system pressure is changing at any time; Actual control effect is very unstable; Sometimes pressure is very high in the lubricating pipe, underpressure again sometimes, and hydraulic oil can not arrive directional post.
?
Summary of the invention
The objective of the invention is to overcome the deficiency of existing accurate four-column guillotine automatic lubricator, a kind of reliable and stable automatic lubricator is provided.
Technological scheme of the present invention: contain valve body, spool, pressure spring, an end of valve body links to each other with the hydraulic system filler opening, and the other end of valve body links to each other with lubricating pipe; Spool one end and valve body are slidingly matched, and the spool the other end is against the ingress of hydraulic oil, between valve body and the spool pressure spring are arranged; Hydraulic oil acts on spool, and spool is slided in valve body, thereby opens the inlet of hydraulic oil; Because it is also different that the size of inlet is opened in the effect of pressure spring, the hydraulic oil of different pressures.
The endoporus and the lubricating pipe of spool communicate; The end at endoporus has aperture radially to lead to the ingress of hydraulic oil; When hydraulic system pressure was too high, spool got into valve body fully, and the aperture on the spool is stopped up by valve body; Thereby close being connected of hydraulic oil inlet and lubricating pipe, prevent too high pressure damage lubricating pipe.
The invention has the beneficial effects as follows: the inlet size of hydraulic oil is adjusted with the variation in pressure of system automatically, when guaranteeing the directional post sufficient lubrication, can prevent to damage when system pressure is too high lubricating pipe again.
Description of drawings
Accompanying drawing is the structural representation of the embodiment of the invention.
Among the figure: the 1---lubricating pipe; The 2---valve body; The 3---sealing gasket; The 4---spool; The 5---pressure spring; The 6---manifold block; 7---hydraulic oil inlet; 8---spool aperture.
Embodiment:
Below in conjunction with accompanying drawing and embodiment the present invention is further specified.
Valve body 2 one ends and manifold block 6 scyewed joint, valve body 2 the other ends link to each other with lubricating pipe 1, and sealing gasket 3 makes valve body 2 and manifold block 6 keep sealing, and spool 4 one ends are against on the hydraulic oil inlet 7; The other end slides in valve body 2, and pressure spring 5 has spool aperture 8 on the spool 4 between valve body 2 and spool 4; Hydraulic oil inlet 7 links to each other with the hydraulic system filler opening, and during work, system pressure oil enters the mouth from hydraulic oil and 7 backs down spool 4; Get into valve body 2 through spool aperture 8, thereby to lubricating pipe 1 fuel feeding, because the effect of pressure spring 5 and spool aperture 8; Make the oil pressure that gets into lubricating pipe 1 keep constant, when system oil pressure was too high, spool 4 was pressed in the valve body 2 fully; Spool aperture 8 is blocked, thereby stops to lubricating pipe 1 fuel feeding, prevents that system pressure oil from damaging lubricating pipe 1.
Claims (2)
