Abstract
The invention discloses a guide device for a slide beam of a hydraulic machine. An upper guide assembly is mounted on the upper end surface of the slide beam; a lower guide assembly is mounted on the lower end surface of the slide beam; the upper guide assembly comprises an L-shaped bracket, a hydraulic cylinder and a roller wheel; one free end of the L-shaped bracket is a coupling end; the roller wheel is coupled to the corner of the L-shaped bracket; a piston rod of a hydraulic cylinder is contacted with another free end of the L-shaped bracket. When the piston rod of the hydraulic cylinder extends out of the hydraulic cylinder, the L-shaped bracket deflects by taking the coupling end as a center, and the roller wheel on the L-shaped bracket is contacted with a guide column. The guide device has the advantages that the roller wheel acts on the column surface of the guide column under the action of the piston rod of the hydraulic cylinder when the slide beam moves up and down; as the roller wheel is in rolling friction with the surface of the guide column, the unbalanced load phenomenon caused when the slide beam moves up and down is avoided and the slide beam can very stably move up and down under the circumstance that the moving speed is more than 800 mm/s.
Description
Technical field
The present invention relates to a kind of travelling mechanism of slide beam of hydraulic machine, especially relate to a kind of guider of slide beam of hydraulic machine.
Background technology
Hydraulic press is widely used in the industries such as national defense industry, machine tool industry, metallurgical industry, auto industry and shipping industry.The operation up and down of current known slide beam of hydraulic machine, relies on the gap between sliding beam and guide upright post, utilizes the deadweight of sliding beam descending, and utilizes the pressure of backhaul hydraulic cylinder to promote sliding beam backhaul.Under above-mentioned about two kinds operating conditions, the speed of service of sliding beam is greater than 800mm/s.Although leave gap between sliding beam and guide upright post, because the center of gravity of sliding beam does not go up at the center point, the unbalance stress acted on lead can be made, thus make sliding beam occur frictional force non-uniform phenomenon in downward running; Sliding beam utilizes backhaul hydraulic cylinder to do, upwards in running, all can occur unbalance loading moment; Make sliding beam occur creeping phenomenon (non-at the uniform velocity move), when situation is serious, then there will be stuck phenomenon, damage the parts of hydraulic press, have a strong impact on production, and bring corresponding economic loss to the producer.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of guider that slide beam of hydraulic machine is operated steadily.
The present invention solves the problems of the technologies described above adopted technical scheme: a kind of guider of slide beam of hydraulic machine, comprise sliding beam, the guide upright post being positioned at sliding beam corner and the guiding mechanism coordinated with guide upright post, described guiding mechanism comprises the identical upper guidance set of structure and lower guidance set, described upper guidance set is arranged on the upper surface of sliding beam, described lower guidance set is in the lower surface of sliding beam, described upper guidance set comprises L-type support, hydraulic cylinder and roller, a free end of described L-type support is pivoted connection end, roller shaft is connected on the turning of L-type support, the piston rod of hydraulic cylinder contacts with another free end of L-type support, , when the piston rod of hydraulic cylinder stretches out, top is to another free end of L-type support, L-type support deflects centered by pivoted connection end, roller in L-type support contacts with column, during the piston rod indentation of hydraulic cylinder, the roller in L-type support leaves guide upright post.
The front end of described piston rod is provided with wear-resisting top, and described wear-resisting top is fixing on the piston rod by locking nut, and described wear-resisting top withstands on inside another free end of L-type support.
Also comprise bearing, described bearing is fixed on the upper surface of sliding beam, the seat that is coupling is provided with at the upper side of bearing, described hydraulic cylinder is arranged on opposite side above bearing, the piston rod of hydraulic cylinder stretches to another free end of L-type support, and a free end shaft of described L-type support is connected on and is coupling on seat.
compared with prior art, advantage of the present invention is under the effect of hydraulic cylinder piston rod, when in the upper and lower running of sliding beam, roller is made to act on the column face of guide upright post, rolling friction is belonged to due to roller and guide upright post face, the unbalance loading phenomenon occurred in the upper and lower running of the sliding beam overcome, makes sliding beam when movement velocity is greater than 800mm/s, can realize very stably running work up and down.When the work that slide beam of hydraulic machine transfers low cruise to by the F.F. operating mode of high-speed cruising is entered to add operating mode, the pressure oil release in the hydraulic cylinder in guider, piston rod is retracted, selects according to actual needs whether to utilize roller.
