Described working solution cylinder pressure is fixed on top in the frame by suspension apparatus, and cylinder bottom contacts and bear service load with frame; The backhaul hydraulic cylinder is suspended in upper rack and is connected described slide block by pull bar.
Lateral prefastened plate frame type hydraulic machine provided by the invention is compared with existing machine technology, and outstanding substantive technical characterstic and significant technological progress are:
1, hydraulic press frame adopts the plate and frame structure, is different from traditional casting, welded structure, has advantages such as manufacturing processing technic is simple, low cost of manufacture.
2, pass through the horizontal pretension of pre-tightening apparatus between the sheet frame, make several sheet frames constitute one and have certain bearing capacity, can satisfy the strength and stiffness requirement of hydraulic press frame fully.
3, hydraulic press adopts the working hydraulic pressure cylinder bottom directly to bear service load, be that the working solution cylinder pressure is fixed on the frame internal upper part by suspension apparatus, the working solution cylinder pressure is connected by flange and compares in this connected mode and the prior art, the strength and stiffness of working solution cylinder pressure have been improved, in other words, compare with the conventional hydraulic machine of onesize service load, reduced hydraulic cylinder weight, also reduced manufacturing cost simultaneously.
4, the inboard transition curve of sheet frame is not a simple right angle circular arc, but the excessive shape line of being made up of oblique line and recessed circular arc, and this excessive shape line produces by optimal design, and it is concentrated that it can reduce the stress of frame to greatest extent.
5, equipment precision height, convenient, the long service life of in light weight, Installation and Debugging, the forged article quality is good.

The specific embodiment
The present invention is described further below in conjunction with accompanying drawing.
Illustrated in figures 1 and 2, lateral prefastened plate frame type hydraulic machine.It comprises the working solution cylinder pressure of installing on forward and backward frame, the frame 3, slide block 4, the workbench 5 that is installed in the frame lower inside and the backhaul hydraulic cylinder 6 that cylinder plunger connects, the front and back frame has three sheet frames respectively, before and after frame have six sheet frames, overlapping of sheet frame and by pre-tightening apparatus 1 horizontal fastening combining.Sheet frame has constituted a frame with hydraulic press of bearing capacity, strength and stiffness.The working solution cylinder pressure is fixed on the frame internal upper part by suspension apparatus 7, and cylinder bottom contacts and bear service load with sheet frame; The backhaul hydraulic cylinder is suspended in upper rack and is connected slide block by pull bar 9, and the working solution cylinder pressure drives slide block with the backhaul hydraulic cylinder and moves up and down.
Laterally pre-tightening apparatus has two kinds, and a kind of is that the hyphen of sheet frame and sheet frame is to pre-tightening apparatus 101, by short high-strength bolt, nut, reach cushion and form.Cushion is contained between sheet frame and the sheet frame, short high-strength bolt laterally runs through the sheet frame of forebay by the hole of sheet frame, or laterally run through the sheet frame of afer bay by the hole of sheet frame, sheet frame and sheet frame are carried out horizontal pretension, just forebay or afer bay are carried out alone horizontal pretension respectively, three sheet frames are fixed as one.And another kind is the horizontal pre-tightening apparatus 102 of length of forebay and afer bay, is made up of the strength bolts of growing tall, nut, resilient sleeve.Resilient sleeve is contained between forebay and the afer bay, cushion is contained between sheet frame and the sheet frame, the strength bolts of growing tall laterally runs through forebay, afer bay by the hole of sheet frame, and with nut to the laterally pre-stressed joint of forebay and afer bay, simultaneously to the laterally also pre-stressed joint of sheet frame and sheet frame, and make forebay and afer bay fixedly become integral body.
Specific embodiments of the present invention is the 60MN lateral prefastened plate frame type hydraulic machine.Frame is made up of six sheet frames 2, the front and back frame each three, at first three sheet frames 2 are installed on the base 8, by hyphen to pre-tightening apparatus 101 with three sheet frame pretensions; Then other three sheet frames are installed on the base, by hyphen to pre-tightening apparatus 101 with other three sheet frame pretensions; At last, by growing horizontal pre-tightening apparatus 102 with six sheet frame 2 pretensions.Laterally the size of pre-tightening apparatus pretightning force is relevant with the hydraulic press rated load.The working solution cylinder pressure is fixed on the sheet frame internal upper part of frame by suspension apparatus 7, cylinder bottom contacts and carries with sheet frame, the working hydraulic pressure cylinder plug is connected with sliding fast 4, and the backhaul hydraulic cylinder is suspended in upper rack and is connected slide block by pull bar 9, and the working solution cylinder pressure drives slide block with the backhaul hydraulic cylinder and moves up and down.Workbench 5 is installed in the sheet frame lower inside.When hydraulic press was worked, six sheet frames 2 bore the longitudinal loading from hydraulic press.
Fig. 3, Fig. 4 and shown in Figure 5, the inboard excessively shape line of each sheet frame all passes through optimal design, and various connecting holes, the installing hole opened on the sheet frame are all wanted reasonable Arrangement, avoid stress to concentrate; The unbalanced transversely deforming that causes stressed between the sheet frame will be controlled by horizontal pre-tightening apparatus fully, and makes and combine closely between the sheet frame and do not crack.
The excessive shape line 201 that the inboard transition curve of each sheet frame is made up of oblique line and recessed circular arc.Wherein: H1, L1 constitute sheet frame lower inside oblique line, and H2, R2 constitute the recessed circular arc of sheet frame lower inside; H3, L2 constitute sheet frame inside upper part oblique line, and H4, R5 constitute the recessed circular arc of sheet frame inside upper part; R1, R3, R4, R6 are the transition arcs between inboard oblique line of sheet frame and the recessed circular arc.
The 60MN lateral prefastened plate frame type hydraulic machine is a kind of centre-line load hydraulic press that bears, and has compact conformation, and bearing capacity is big, the light and precision advantages of higher of weight of equipment.It is the ideal equipment of aluminium alloy wheel hub of vehicle moulding.Also can make other industry uses.
