A kind of twin-tub is to topped hydraulic machine
This utility model relates to a kind of hydraulic press, and especially a kind of twin-tub is to topped hydraulic machine.
Hydraulic press is a kind of to utilize hydrostatic pressure to process the plant equipment of the goods such as metal, plastics, rubber, timber, powder. It is usually used in pressing process and block pressing forming process, as: forging and stamping, cold-extruded, process of sheet drawing, press-fit. Its principle is the machinery utilizing liquid pressure transmission made according to Pascal's law.
Traditional hydraulic press, only rely on a hydraulic cylinder being positioned at fuselage roof to drive walking beam to do single lower top type motion, owing to workpiece can only be carried out unidirectional compacting, in the pressing process of large-scale plate-type work, easily cause press strengthi inadequate, the problems such as press power is uneven, thus affecting the crudy of product.
Summary of the invention
It is big that problem to be solved in the utility model is to provide a kind of press strengthi, and press power is uniform, have double hydraulic cylinder structure to topped hydraulic machine.
For solving above-mentioned technical problem, the technical solution adopted in the utility model is: a kind of twin-tub is to topped hydraulic machine, including back timber, upper walking beam, master cylinder, guide upright post, locking nut, flange, secondary cylinder, lower walking beam, base and electrical control cabinet, it is characterized in that: described back timber and base, with guide upright post for body frame, are fastened at the two ends up and down of guide upright post respectively by locking nut; Described master cylinder is arranged on back timber, and secondary cylinder is arranged on base; It is used that Flange joint between described master cylinder and upper walking beam and between secondary cylinder and lower walking beam; Described upper walking beam and lower walking beam with guide upright post for guiding, do in the scope between back timber and base and top formula are moved back and forth respectively; Described electrical control cabinet is positioned on the right side of base, is connected with master cylinder, secondary cylinder by pipeline.
Owing to adopting technique scheme, by being separately positioned on master cylinder on back timber and base and secondary cylinder, in drivings, walking beam and lower walking beam do the reciprocating motion of top formula, from relative both direction, workpiece are suppressed, add press strengthi, improve the uniformity of press power.
For the ease of installing workpiece, improving piece-holder precision, described upper walking beam and lower walking beam surface are provided with T-slot.
In order to improve the guiding accuracy of guide upright post, it is ensured that guiding steady is qualitative, described upper walking beam is connected position with guide upright post and lower walking beam is connected with guide upright post, and position is respectively arranged with fairlead.
The beneficial effects of the utility model are: in large-scale plate-type work pressing process, have press strengthi big, and the uniform advantage of press power, thus improve the crudy of product.

Detailed description of the invention
As it is shown in figure 1, this utility model be a kind of twin-tub to topped hydraulic machine, including back timber 3, upper walking beam 4, master cylinder 1, guide upright post 5, locking nut 2, flange 9, secondary cylinder 8, lower walking beam 6, base 7 and electrical control cabinet 11; Described back timber 3 with guide upright post 5 for body frame, is fastened at the two ends up and down of guide upright post 5 with base 7 respectively by locking nut 2; Described master cylinder 1 is arranged on back timber 3, and secondary cylinder 8 is arranged on base 7, is used that flange 9 is connected between master cylinder 1 with upper walking beam 4 and between secondary cylinder 8 and lower walking beam 6; Described upper walking beam 4 and lower walking beam 6 are respectively with guide upright post 5 for guiding, do in scope between back timber 3 and base 7 and top formula is moved back and forth, the surface of upper walking beam 4 and lower walking beam 6 is provided with T-slot 601, and upper walking beam 4 is connected position with guide upright post 5 and lower walking beam 6 is connected with guide upright post 5, and position is respectively arranged with fairlead 602; Described electrical control cabinet 11 is positioned on the right side of base 7, is connected with master cylinder 1, secondary cylinder 8 by pipeline 10.
The work process of this example: first, workpiece is fixed in the T-slot 601 of lower walking beam 6, then, it is operated by electrical control cabinet 11 and controls master cylinder 1 and secondary cylinder 8, on driving respectively under the pressure action of working solution, walking beam 4 and lower walking beam 6 rely on guide upright post 5 guiding top formula of opposing to move back and forth, and workpiece is suppressed.
Above embodiment of the present utility model is described in detail, but described content has been only preferred embodiment of the present utility model, it is impossible to be considered for limiting practical range of the present utility model. All equalizations made according to this utility model scope change and improvement etc., all should still belong within this patent covering scope.
