Abstract
The invention relates to a double-column upper driven high-speed forging hydraulic press, comprising an upper beam, a lower beam, a stand column, side frames, a movable beam and a stroke cylinder. The upper beam at the top of the device is connected with the lower beam at the bottom end through the stand column; the upper end of a primary working cylinder passes through the upper beam and is fixed to the upper beam; the lower end is connected with the movable beam which consists of a side frame and a movable beam; the side frame is connected with the movable beam as a whole through a bolt; the side frames are distributed at both sides of the hydraulic press and are connected through the movable beam; the lower end of the stroke cylinder is fixedly mounted on the lower beam; and the upper end of the stroke cylinder is connected with the side frames. The device has reasonable structural design, high processing precision and high working efficiency and effectively improves the productivity effect of enterprises.
Description
Technical field
The present invention relates to a kind of hydraulic test, particularly related to a kind of double-column upper driven high-speed forging hydraulic press.
Background technology
The at present domestic high speed forging hydraulic press that generally uses, its nominal pressure is 30MN, 38MN, the high speed forging hydraulic press of this specification, the workpiece tonnage that is forged is little, can not satisfy actual needs: hydraulic press walking beam and crossbeam are one, and three on this structure contacts with column, and kinematic accuracy is low, discontinuity, the forging precision is low; Hydraulic press is the valve transmission, and this transmission system wastes energy; It is that (30---40) are inferior/MIN that the hydraulic press per minute forges number of times, and production efficiency is low.
Summary of the invention
The present invention has overcome deficiency of the prior art, and a kind of reasonable in design, high efficiency are provided, the double-column upper driven high-speed forging hydraulic press that machining accuracy is high.
In order to address the above problem, the present invention by the following technical solutions:
Double-column upper driven high-speed forging hydraulic press, comprise main working cylinder, entablature, sill, column, bogie side frame, moving beam and kicker cylinder, the entablature on this equipment top is connected by column with the sill of bottom, main working cylinder upper end is passed entablature and is fixed with entablature, the lower end is connected with moving beam, moved cross beam is made up of bogie side frame and moving beam two parts, and bogie side frame and moving beam connect as one by bolt; Moving beam connection is also passed through in bogie side frame distribution hydraulic press both sides; The kicker cylinder lower end is fixedly mounted on the sill, and the upper end is connected with bogie side frame,
Be provided with two columns between entablature and the sill, be provided with 5 alloy pull bars in each column, the pull bar top is fixed by nut check; Be provided with 10 alloy pull bars in each column, the pull bar top is fixed by nut check; Hydraulic press adopts oil pump direct drive.
Compared with prior art, the invention has the beneficial effects as follows:
1, adopts many cylinder pull bar prestressed frame structures, be installed with the high-strength alloy pull bar in the column, form the rigid frame of a sealing, improved the holding capacity of hydraulic press in forging greatly.
2, moved cross beam is made up of bogie side frame and moving beam, and bogie side frame and moving beam connect as one by bolt, effectively raise kinematic accuracy.
3, hydraulic press adopts oil pump direct drive, effectively reduces equipment failure rate, can forge the big alloyed steel work-piece of 20 tonnages.
Description of drawings
Fig. 1 is a structural representation of the present invention
The specific embodiment
Double-column upper driven high-speed forging hydraulic press, comprise entablature 4, sill 9, column 5, bogie side frame 6, moving beam 7 and kicker cylinder 8, the entablature 4 on this equipment top is connected by two columns 5 with the sill 9 of bottom, be provided with 5～10 alloy pull bars 1 in each column 5, pull bar 1 top is locked by nut 3; Entablature 4 and fixing with entablature 4 is passed in main working cylinder 2 upper ends, and main working cylinder 2 adopts flange to be connected with entablature 4; Main working cylinder 2 lower ends are connected with moved cross beam, and moved cross beam is made up of bogie side frame 6 and moving beam 7 two parts, and bogie side frame 6 and moving beam 7 connect as one by bolt; Main working cylinder 2 lower ends adopt two ball pivots to be connected with moving beam 7; Moving beam 7 connections are also passed through in bogie side frame 6 distribution hydraulic press both sides; Kicker cylinder 8 lower ends are fixedly mounted on the sill 9 and by bolting, the upper end is connected with bogie side frame 6,
Hydraulic press adopts oil pump direct drive, and this Chuan Dong Xi System fault rate is supported, and production efficiency improves greatly.
