Abstract
The invention discloses a crossbeam structure for small and medium-size hydraulic machines. The crossbeam structure comprises a crossbeam main body, wherein an upper crossbeam, a lower crossbeam and a moving crossbeam form a box body structure which is closed in an up-and-down mode, positions for installation of various cylinders, plungers and upright posts are in cylindrical shapes and are connected with crossbeam surfaces through rib plates, at positions with large loads, most rib plates are arranged in a radiation shape, crossbeams are made of iron castings HT200 or steel castings ZG500 and are welded through 16Mn plates, simultaneously, the upper crossbeam is in such a structure that the height of the middle portion of the crossbeam is higher than that of two ends, and the transition fillet radius R is enlarged, the angle of tilt is reduced and a main cylinder and the upper crossbeam are cast into a whole in height transition areas of the beam. The crossbeam structure has the advantages of being beneficial to improvement of machine movement precision and reduction of abrasion of guide faces, capable of prolonging the service life, assisting machine body stressing and the like, beneficial to adaptation to requirements of transportation, installation and adjustment and capable of improving operation controllability and reducing the labor intensity.
Description
Technical field
The present invention relates to the hydraulic technique field, relate in particular to a kind of beam structure of medium-small hydraulic press.
Background technology
Hydraulic system has that power is large, operating pressure and the flow adjustability is good, heat can be brought back the advantages such as fuel tank, adopt hydraulic system to produce more power than other devices, under equal power, the volume of hydraulic means is little, lightweight, power density large, compact conformation; Simultaneously, the hydraulic means Comparision is steady because lightweight, inertia is little, reaction is fast, hydraulic means is easy to realize quick startup, braking and commutating frequently.Along with the development of China's industry and science and technology, hydraulic transmission technology has obtained at aspects such as auto industry, shipbuilding industry, power industries using more and more widely, and hydraulic press is more and more welcomed by the people also.The working cycles of hydraulic press generally comprise stop, eharge stroke, impulse stroke and backhaul, above-mentioned different strokes are realized by the action of various valves in the control system control hydraulic system.But the hydraulic system transmission component for the hydraulic press that has the shipbuilding field now exists a lot of problems from method of operating, working method, numerous and diverse different angles such as structure, and this causes work poor efficiency, heavier, the high expensive of weight of equipment.
Summary of the invention
But the purpose of this invention is to provide a kind of balanced load, can improve hydraulic efficient, simple in structure, can reduce labour intensity, the auxiliary beam structure that improves the medium-small hydraulic press of equipment operation ability, to solve many deficiencies of prior art.
Purpose of the present invention is come specific implementation by the following technical programs:
A kind of beam structure of medium-small hydraulic press mainly is comprised of following steps:
⑴ form the up and down body structure of sealing by main body of cross-beam by entablature, sill and moved cross beam, is made into cylindrical shape at the various cylinders of installation, plunger and column place, and links to each other with the crossbeam face with gusset;
⑵ in the larger position of carrying, and gusset is arranged to radiation shapes more, and crossbeam adopts ironcasting HT200 or steel-casting ZG500, and by the welding of 16Mn sheet material, simultaneously, entablature is arranged to the middle part height structure slightly high than two ends of beam;
⑶ in the depth of beam transition region, increases radius R and reduces the inclination angle and with master cylinder and entablature cast solid;
⑷ be set to height a little less than entablature at the moved cross beam that carries out working under the eccentric load condition, and the identical enclosed housing of wall thickness.
The beneficial effect of the beam structure of medium-small hydraulic press of the present invention is: be conducive to improve the machine movement precision and reduce the abrasion condition of spigot surface, can increase the service life and the auxiliary machine power etc. of experiencing; Simultaneously, be conducive to adapt to the demand of transportation, installation, accent frame, can improve the operation controllability, reduce labour intensity.
The specific embodiment
The beam structure of the described medium-small hydraulic press of the embodiment of the invention, its key step comprises:
⑴ form the up and down body structure of sealing by main body of cross-beam by entablature, sill and moved cross beam, is made into cylindrical shape at the various cylinders of installation, plunger and column place, and links to each other with the crossbeam face with gusset;
⑵ in the larger position of carrying, and gusset is arranged to radiation shapes more, and crossbeam adopts ironcasting HT200 or steel-casting ZG500, and by the welding of 16Mn sheet material, simultaneously, entablature is arranged to the middle part height structure slightly high than two ends of beam;
⑶ in the depth of beam transition region, increases radius R and reduces the inclination angle and with master cylinder and entablature cast solid;
⑷ be set to height a little less than entablature at the moved cross beam that carries out working under the eccentric load condition, and the identical enclosed housing of wall thickness.
