Summary of the invention
In the utility model solution prior art, the slide block lift structure of general high velocity ram machine does not have the problem of effective workout cost height and unstable properties, a kind of slide block lifting device is provided, by the combined innovation of slide block, lift cylinder and connecting plate and syndeton thereof, realizing this slide block lifting device, to have structure simple, stable performance, cost is low, easy installation and removal, the inspection and maintenance of high velocity ram machine is convenient, the feature of main oil pressure cylinder long service life.
In order to solve the technical problem of above-mentioned existence, the utility model takes following technical proposals: a kind of slide block lifting device, comprise slide block, lift cylinder and connecting plate, it is characterized in that, described connecting plate is connected with the bearing shell of bent axle, described slide block is provided with master cylinder, described master cylinder is provided with the main piston be connected with connecting plate, described main piston is provided with the main hydraulic valve be connected with master cylinder, described lift cylinder and slide block fix, divide the both sides being located at master cylinder, described lift cylinder is equipped with the jigger lifting piston be threaded with connecting plate, the epicoele of lift cylinder is provided with oil drain out.
When high velocity ram machine carries out normal press work, lift cylinder does not work, and the bent axle of high velocity ram machine drives connecting plate and main piston to move up and down, thus slide block carries out the operation of punching press.High velocity ram machine need repairing mould or check all parts of high velocity ram machine time, the bent axle of high velocity ram machine quits work, the synchronous oil-feed of oil drain out of lift cylinder, the upper cavity pressure of lift cylinder increases, and jigger lifting piston is retracted lift cylinder gradually, slide block is promoted, due to bent axle and connecting plate motionless, the pressure increase in master cylinder, the hydraulic oil in master cylinder is discharged through main hydraulic valve, distance now between slide block and connecting plate reduces gradually, reaches the object increasing die sinking height; When needs reset, the synchronous oil-feed of master cylinder, pressure increase in master cylinder, slide block is ejected downwards, due to bent axle and connecting plate motionless, the upper cavity pressure of lift cylinder increases, and the hydraulic oil in epicoele is discharged through oil drain out, distance now between slide block and connecting plate increases gradually, reaches the object that slide block resets.The structure of two lift cylinders and corresponding jigger lifting piston, both ensured to promote the steady of slide block process, strengthened again the bonding strength of slide block and bent axle, and more effectively can eliminate the gap of each connecting portion simultaneously, combine with the structure of master cylinder and main piston, stuctures and properties is more stable; The slide block lifting device of high velocity ram machine of the present utility model, by increasing the lifting oil hydraulic cylinder of lift cylinder and jigger lifting piston composition, achieve the lifting of slide block, facilitate the inspection and maintenance of high velocity ram machine, realize comparing with main piston with by the master cylinder on slide block, greatly reduce the hoisting power of slide block, cost-saving, also reduce the number of times of master cylinder positive action simultaneously, extend the service life of master cylinder and main piston.
As preferably, described oil drain out is equipped with lifting hydraulic valve.Facilitate oil-feed and the oil extraction of lift cylinder, can effectively prevent the foreign matters such as dust from entering lift cylinder simultaneously, guarantee the stable of lift cylinder performance.
As preferably, between described lift cylinder and corresponding jigger lifting piston, be provided with three seals circle.The junction leakage of oil of effective reduction lift cylinder and jigger lifting piston, reduces the waste of hydraulic oil, cost-saving.
As preferably, described connecting plate is connected by bolt with bearing shell.Structure is simple, and installation and removal are convenient.
As preferably, described connecting plate is connected by bolt with main piston.Structure is simple, and installation and removal are convenient.
Owing to taking above-mentioned technical scheme, a kind of slide block lifting device that the utility model provides has such beneficial effect: by the combined innovation of slide block, lift cylinder and connecting plate and syndeton thereof, there is provided a kind of structure simple, stable performance, cost is low, easy installation and removal, the inspection and maintenance of high velocity ram machine is convenient, the slide block lifting device of main oil pressure cylinder long service life.
