Abstract
The utility model relates to an air cushion buffer structure of a press machine, which belongs to the technical field of press machines. The utility model is mainly characterized in that a buffer piston and an one-way intercepting valve which forms a buffer cavity and is connected with an upper air cavity and the buffer cavity are arranged between a clapboard and a lower piston; when the press machine works, a sliding block falls and simultaneously the air cushion falls; an upper piston and the lower piston are pressed down; the buffer piston freely falls to a supporting location; the air of an upper air cylinder is pressed into the buffer cavity by the one-way channel of the one-way intercepting valve; when the sliding block returns, the air cushion also follows to return; the upper piston and the lower piston rise; the lower piston props against the buffer piston to rise; the air in the buffer cavity is compressed; the air returns to the upper air cylinder from the one-way channel of the one-way intercepting valve; the piston of the air cushion forms a slowly rising process when rising, thereby achieving the goal of air cushion buffer. The utility model has a simple structure, is suitable for altering the air cushions of the existing relative press machines, is beneficial to reducing the impact of an apical cap to a working platform during the returning process of the air cushion, and improves the service life of the press machine.
Description
Technical field
The utility model relates to a kind of forcing press air cushion buffer structure, help reducing opening speed in the use of forcing press air cushion, avoid long-term impact workbench to cause the phenomenon of the loosening fracture of set bolt, also can satisfy more Sheet Metal Forming Technology requirement, belonged to the press technologies field.
Background technology
The forcing press air cushion is mainly used in flanging and head part.Air cushion ejects ejector beam, ejects workpiece by the air cushion apical cap, when the air cushion rate of climb is too fast when work, apical cap impacts workbench, and it is also too fast that ejector beam ejects work speed, brings a lot of inconvenience to the operator, simultaneously long-term impact workbench has also damaged equipment.
Summary of the invention
The purpose of this utility model is fast at existing forcing press air cushion work opening speed, and workbench is had the deficiency of impact, has efficient buffer when backhaul is provided, thereby effectively reduces a kind of forcing press air cushion buffer structure that apical cap impacts workbench.
The purpose of this utility model is achieved through the following technical solutions, a kind of forcing press air cushion buffer structure, comprise the dividing plate between upper cylinder, lower cylinder, upper and lower air cylinders, pass the piston rod of dividing plate, the upper piston that piston rod portion in the upper cylinder is fixing, the lower piston that piston rod portion in the lower cylinder is fixing, support ring in the lower cylinder of dividing plate below, it is characterized in that, piston rod portion between dividing plate and the lower piston is provided with damper piston, constitute a cushion chamber between damper piston and dividing plate, the air cavity in the upper cylinder is connected by the unidirectional shutoff valve that is provided with cushion chamber.
The air flue of cushion chamber in dividing plate is connected with unidirectional shutoff valve with an air inlet, and unidirectional shutoff valve another air flue in another air inlet, dividing plate is connected with upper gas chamber.
The utility model is the improvement to existing forcing press air cushion structure, damper piston is set between dividing plate and lower piston and forms cushion chamber and be connected upper gas chamber and the unidirectional shutoff valve of cushion chamber, when forcing press is worked, slide block falls, air cushion falls simultaneously, last lower piston is depressed, the damper piston freely falling body is to support place, the gas of upper cylinder is pressed in the cushion chamber by the half-duplex channel of unidirectional shutoff valve, be full of atmosphere in the cushion chamber, when the slide block backhaul, when air cushion is also followed backhaul, last lower piston rises, lower piston heads on damper piston and rises, and the gas in the cushion chamber is compressed, and gas is got back in the upper cylinder by the half-duplex channel of unidirectional shutoff valve, make air-spring piston when rising, form a process that slowly rises by the mode of damming, thereby reached the purpose of air cushion buffering, the utility model is simple and practical, is applicable to and transforms existing related pressure machine air cushion, reduce the impact of apical cap when helping the air cushion backhaul, improve the service life of forcing press workbench.
Description of drawings
Fig. 1 is installed in main TV structure schematic diagram on the forcing press for the utility model;
Fig. 2 is installed in left TV structure schematic diagram on the forcing press for the utility model;
Among the figure, 1 upper piston, 2 upper gas chambers, 3 cushion chambers, 4 damper pistons, 5 lower pistons, 6 lower air chambers, 7 support rings, 8 unidirectional shutoff valves, 9 dividing plates, 10 piston rods, 11 lower cylinders, 12 upper cylinders, A air inlet, B air inlet.
The specific embodiment
Further specify the utility model in conjunction with the accompanying drawings and embodiments, as Fig. 1, shown in 2, the utility model is by upper cylinder 12, lower cylinder 11, upper cylinder 12, the dividing plate 9 that lower cylinder is 11, pass the piston rod 10 of dividing plate 9,10 fixing upper pistons 1 of piston rod in the upper gas chamber 2 of dividing plate 9 tops, the fixing lower piston 5 in piston rod 10 ends in the lower air chamber 6 of dividing plate 9 belows, the damper piston 4 that piston rod between dividing plate 9 and the lower piston 5 is 10 ones, the cushion chamber 3 of damper piston 4 and 9 formations of dividing plate, the support ring 7 in unidirectional shutoff valve 8 that upper gas chamber 2 is connected with 3 of cushion chambers and the lower cylinder 11 constitutes.The air flue of cushion chamber 3 in dividing plate 9 is connected with unidirectional shutoff valve 8 with the A air inlet, and unidirectional shutoff valve 8 another air flue in B air inlet, dividing plate 9 is connected with upper gas chamber 2.
During air cushion work, when upper piston 1 and lower piston 5 fell, damper piston 4 dropped to support ring 7 places, passes through unidirectional shutoff valve 8 gassies by air inlet A in the cushion chamber 3; When upper piston 1, lower piston 5 backhauls, lower piston 5 heads on damper piston 4 and rises, and the gas in the cushion chamber 3 is got back in the upper gas chamber 2 by unidirectional shutoff valve 8 by air inlet B, forms a buffering course, by regulating the speed effect of unidirectional shutoff valve 8 control bufferings.
