Abstract
The utility model discloses a return mechanism of hydraulic press which facilitates the exchanging of working cylinder guide sleeve. The return mechanism of hydraulic press comprises a return cylinder which is installed on a lower beam and is provided with a plunger piston. The plunger piston is connected with a movable beam through a center pole. Two ends of center pole are respectively connected with the plunger piston and the movable beam detachably. The center pole is installed between the plunger piston and the movable beam of return cylinder. When the working cylinder guide sleeve is exchanged, the center pole can be detached so that the movable beam moves to an enough low position so as to facilitate the exchanging of working cylinder guide sleeve. The return mechanism of hydraulic press according to the utility model is especially suitable for the large-scale open-die forging hydraulic press.
Description
Technical field
The utility model relates to hydraulic press, is specifically related to the backhaul mechanism of hydraulic press.
Background technology
What the main machine structure of existing large free forging hydraulic press adopted is the beam column construction form.The beam column construction form mainly comprises three beams, four posts, be entablature, sill, moved cross beam and four root posts, the two ends of described each column are passed entablature and sill respectively and by interior outer nut and entablature and fastening the linking together of sill, the space frame of forming a rigidity bears whole service loads of hydraulic press.Wherein, be fixed with working cylinder on the entablature of hydraulic press, the work plunger is housed in the working cylinder, the work plunger is connected with moved cross beam.Moved cross beam is a guiding with four root posts, drives by working cylinder to move back and forth between upper and lower crossbeam.The both sides of sill also are provided with backhaul mechanism, and this backhaul mechanism comprises and be installed in the kicker cylinder that has plunger on the sill that described plunger is connected with moved cross beam.After kicker cylinder starts, promote plunger and move upward, realize drawback movement thereby drive moved cross beam.Because the plunger of existing hydraulic press kicker cylinder directly is connected with moved cross beam, like this when changing the working cylinder guide pin bushing, because the restriction of kicker cylinder stroke, the moved cross beam height of drop is limited, the work plunger can't withdraw from working cylinder fully, therefore in order to change the working cylinder guide pin bushing, the backhaul cylinder plug of must dismantling is wasted time and energy.
The utility model content
The technical problem that the utility model solved is: a kind of backhaul mechanism of being convenient to hydraulic press that the working cylinder guide pin bushing is changed is provided.
The technical scheme that solves the problems of the technologies described above is: the backhaul mechanism of hydraulic press, comprise and be installed in the kicker cylinder that has plunger on the sill, described plunger is connected with moved cross beam by intermediate bar, and the two ends of described intermediate bar removably connect with plunger and moved cross beam respectively.
The beneficial effects of the utility model are: be provided with intermediate bar between the plunger of kicker cylinder and the moved cross beam, when changing the working cylinder guide pin bushing, intermediate bar can be pulled down, it is enough low that moved cross beam is come to, the assurance work plunger cylinder of deactivating fully, thus be convenient to change the working cylinder guide pin bushing.The backhaul mechanism of the application's hydraulic press is particularly useful for the large free forging hydraulic press.
Description of drawings
Fig. 1 is the partial structurtes schematic diagram of the backhaul mechanism of the application's hydraulic press.
Fig. 2 is the scheme of installation of the backhaul mechanism of the application's hydraulic press.
Be labeled as among the figure: kicker cylinder 1, plunger 2, intermediate bar 3, last intermediate bar 4, moved cross beam 5.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further.
As depicted in figs. 1 and 2, the backhaul mechanism of hydraulic press of the present utility model, comprise being installed in the kicker cylinder 1 that has plunger 2 on the sill, described plunger 2 is connected with moved cross beam 5 by intermediate bar 3, and the two ends of described intermediate bar 3 removably connect with plunger 2 and moved cross beam 5 respectively.Be provided with intermediate bar 3 between the plunger 2 of kicker cylinder 1 and the moved cross beam 5, when changing the working cylinder guide pin bushing, intermediate bar 3 can be pulled down, it is enough low that moved cross beam 5 is come to, and guarantees the work plunger cylinder of deactivating fully, thereby be convenient to change the working cylinder guide pin bushing.
For making the stressed more reasonable of intermediate bar 3, and for convenience detach, Fig. 1 is connected with moved cross beam 5 by last intermediate bar 4 with the intermediate bar 3 shown in Fig. 2, and described upper end of going up intermediate bar 4 is connected with moved cross beam 5 ball pivots, and lower end and intermediate bar 3 removably connect.
Claims (2)
1. the backhaul mechanism of hydraulic press, comprise and be installed in the kicker cylinder (1) that has plunger (2) on the sill, it is characterized in that: described plunger (2) is connected with moved cross beam (5) by intermediate bar (3), and the two ends of described intermediate bar (3) removably connect with plunger (2) and moved cross beam (5) respectively.
2. the backhaul mechanism of hydraulic press as claimed in claim 1, it is characterized in that: described intermediate bar (3) is connected with moved cross beam (5) by last intermediate bar (4), described upper end of going up intermediate bar (4) is connected with moved cross beam (5) ball pivot, and lower end and intermediate bar (3) removably connect.
