Abstract

The utility model relates to a lifting and pressing device for a moving working table of a stretching forming hydraulic press machine, which comprises a guide rail support, the moving working table and hydraulic oil cylinders, wherein the moving working table is connected on the guide rail support, four angles of the lower end surface are respectively connected with the hydraulic oil cylinders, the piston rod of each hydraulic oil cylinder is a double-piston rod structure, and a limit nut is connected at the tail end of each piston rod. By adopting the double piston rods, the device realizes integration of lifting and pressing, and having more compact structure; limit nuts with the same stroke are connected at the tail ends of the double pistons so as to lift and position, and lifting is guaranteed to be identical; and by adopting the structure, the lifting working efficiency of the moving work table is improved, without the need of checking whether the pressing cylinder is withdrawn to a proper position.

Description

A kind of drawing and forming movable workbench of hydraulic press lifting hold down gag
Technical field
The utility model relates to a kind of drawing and forming movable workbench of hydraulic press lifting hold down gag, contains rail brackets, travelling table and hydraulic jack, is connected with travelling table on this rail brackets, is connected with hydraulic jack respectively on four angles of lower surface,
Background technology
Traditional drawing and forming movable workbench of hydraulic press lifting hold down gag adopts hydraulic pressure to take blame for others and compressed oil cylinder lifts and compresses travelling table respectively, owing to lift pressure, highly inconsistent, make travelling table outwards to move smoothly, and be difficult to accomplish interlock with hold-down cylinder, must check to compress to withdraw from whether put in place, it is long to carry away the travelling table time, influences operating efficiency.
The utility model content
The technical problems to be solved in the utility model provides that a kind of lifting compresses that integrated, technological action process is simple, compactness and the high drawing and forming movable workbench of hydraulic press lifting hold down gag of lifting efficient.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of drawing and forming movable workbench of hydraulic press lifting hold down gag, contain rail brackets, travelling table and hydraulic jack, be connected with travelling table on the described rail brackets, be connected with hydraulic jack respectively on four angles of lower surface, its innovative point is: the piston rod of described hydraulic jack is the double piston-rod structure, and is connected with stop nut at the end of piston rod.
Further, described stop nut side is connected with holding screw, and the end face of described holding screw is against on the piston rod.
Advantage of the present utility model is: by double piston-rod make lifting, clamp integratedly, structure is compact more, connecting the identical stop nut of stroke at the end of double piston-rod is the lifting location, guarantees to lift unanimity; Connect holding screw in the stop nut side, always prevent in the hydraulic press operation, stop nut shakes, and influences the synchronous requirement of the lifting stroke and four cylinder bodies of piston rod.Adopt this structure, need not check that hold-down cylinder withdraws from whether to put in place, improved the lifting efficient of travelling table.
Description of drawings
Figure is the structural representation of a kind of drawing and forming movable workbench of hydraulic press lifting hold down gag of the present utility model.
The specific embodiment
As shown in the figure, comprise rail brackets 1, stationary work-table 9, travelling table 3, guide pin bushing 2, hydraulic jack 4, pressure cap 5, lower flange 6, piston rod 7, stop nut 8, holding screw 10.
Above-mentioned rail brackets 1 is connected in stationary work-table 9 chambeies by guide pin bushing 2, and the upper surface is connected with travelling table 3, is connected with hydraulic jack 4 respectively on four angles of lower surface.
Integrated for realizing that lifting clamps, hydraulic jack 4 has been done improvement, its concrete structure is: the upper end of hydraulic jack 4 is connected with pressure cap 5, end is fixed with lower flange 6, be connected with piston rod 7 in the chamber, described piston rod 7 is a double piston-rod, and is connected with stop nut 8 at the end of piston rod 7.
During lifting, the piston rod 7 of hydraulic jack 4 moves up, promote the rail brackets 1 and travelling table 3 liftings on top, because the end of piston rod 7 is connected with stop nut 8, when stop nut 8 with after the lower flange 6 of hydraulic jack 4 contacts, move on stopping,, guaranteed the angle unanimity of four angle liftings because four hydraulic jacks 4 are subjected to a HYDRAULIC CONTROL SYSTEM; During clamping, the same with lifting, the piston rod 7 drive rail bracketses 1 of hydraulic jack 4 move down into travelling table 3 to be close to above the stationary work-table 9, utilizes the pressure of hydraulic jack 4 to make rail brackets 1 continue to press down, and reaches the purpose that compresses travelling table 3.
Be connected with holding screw 10 in stop nut 8 sides, the end face of this holding screw 10 is against on the piston rod 7 to prevent hydraulic press in operation, and stop nut 8 shakes, thus the fixed journey system that influence regulates.

Claims (2)

1. drawing and forming movable workbench of hydraulic press lifting hold down gag, contain rail brackets, travelling table and hydraulic jack, be connected with travelling table on the described rail brackets, be connected with hydraulic jack respectively on four angles of lower surface, it is characterized in that: the piston rod of described hydraulic jack is the double piston-rod structure, and is connected with stop nut at the end of piston rod.
2. a kind of drawing and forming movable workbench of hydraulic press lifting hold down gag according to claim 1, it is characterized in that: described stop nut side is connected with holding screw, and the end face of described holding screw is against on the piston rod.
