Hydraulic press is a kind of machinery utilizing hydrostatic pressure to carry out the goods such as processing metal, plastics, rubber, timber, powder.It is usually used in pressing process and block pressing forming process, as: forging and stamping, punching press, cold-extruded, alignment, bending, flange, process of sheet drawing, powder metallurgy, press-fits etc.Existing hydraulic press divides by structural shape, and have the patterns such as twin columns, four posts, eight posts, lead frame and multilayer steel band wrapped box frame, wherein medium and small vertical hydraulic press often uses single arm type, and also referred to as C type frame formula, C-frame hydraulic press three opens wide, easy to operate.But existing various hydraulic press, especially C-frame hydraulic press, only arranges a hydraulic cylinder, make working ability limited, such as when processing some and needing the workpiece of Multi-stage ram, special Multi-stage ram mould must be used, increase design difficulty and production cost.
Summary of the invention
The object of the invention is to for the deficiencies in the prior art, and a kind of multiaxis hydraulic press is provided, its scientific structure, improve the working ability of hydraulic press, easy to use.
The technical solution adopted for the present invention to solve the technical problems is: a kind of multiaxis hydraulic press, it comprises frame, described frame comprises support, support arm, oil cylinder seat, described support is provided with workbench, described oil cylinder seat is positioned at above described workbench, described oil cylinder seat is connected with described support by support arm, and described oil cylinder seat is provided with at least two hydraulic jacks, and the axis of described hydraulic jack is vertically arranged.
Wherein, described hydraulic jack is two, and described two hydraulic jacks are arranged along the horizontal direction of described workbench.
Or described hydraulic jack is two, described two hydraulic jacks are arranged along the longitudinal direction of described workbench.
Or described hydraulic jack is three, described three hydraulic jacks are arranged along the horizontal direction of described workbench.
Or described hydraulic jack is three, described three hydraulic jacks are arranged along the longitudinal direction of described workbench.
Further, described frame is connected with the position sensor of the position of the push rod detecting described hydraulic jack, and the output of described position sensor is electrically connected with the controller of described hydraulic jack.
Further, the push rod of described hydraulic jack is connected with position indicating arm, and the free end of described position indicating arm stretches to described position sensor.
The invention has the beneficial effects as follows: a kind of multiaxis hydraulic press, it comprises frame, described frame comprises support, support arm, oil cylinder seat, described support is provided with workbench, described oil cylinder seat is positioned at above described workbench, described oil cylinder seat is connected with described support by support arm, described oil cylinder seat is provided with at least two hydraulic jacks, the axis of described hydraulic jack is vertically arranged, scientific structure of the present invention, it is by arranging multiple hydraulic jack at oil cylinder seat, each hydraulic jack both can simultaneously work compound, many places multiple operation punching press is carried out to workpiece, the all right operation separately of each hydraulic jack, use as two hydraulic presses, thus improve the working ability of hydraulic press, reduce the cost of enterprise, easy to use.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation, is not practical range of the present invention is limited to this.
As shown in Figure 1 and Figure 2, the multiaxis hydraulic press of the present embodiment, it comprises frame 1, described frame 1 comprises support 11, support arm 12, oil cylinder seat 13, described support 11 is provided with workbench 2, described oil cylinder seat 13 is positioned at above described workbench 2, described oil cylinder seat 13 is connected with described support 11 by support arm 12, described oil cylinder seat 13 is provided with at least two hydraulic jacks 3, the axis of described hydraulic jack 3 is vertically arranged, during use, the push rod of hydraulic jack 3 can vertically move up and down.In order to improve the stability of hydraulic press, support arm 12 and support 11 can be strengthened, such that hydraulic press does not shake at work complete machine, support arm 12 not flexural deformation.Two or more hydraulic jacks 3 can work compound, such as, when correcting concentricity to the two ends of axle shell, two hydraulic jacks 3 can be used to press the two ends of axle housing respectively.Two or more hydraulic jacks 3 also can operation separately, such as in the front end of two hydraulic jacks 3, different moulds is installed respectively, different workpiece can be processed separately, so just can complete the work of two equipment with an equipment, not need frequent more mold exchange.
Further, described hydraulic jack 3 can be two, and described two hydraulic jacks 3 are arranged along the horizontal direction of described workbench 2, the horizontal direction of workbench 2 refers to the front standing in workbench 2, direction from left to right, in the direction in which, the space, both sides of hydraulic press is comparatively large, easy to operate.
The arrangement of hydraulic jack 3 also can be adopted in another way, and described hydraulic jack 3 is two, and described two hydraulic jacks 3 are arranged along the longitudinal direction of described workbench 2, and this layout is especially applicable to the workpiece of processing needs Multi-stage ram.
Preferably, as shown in Figure 1, described hydraulic jack 3 is three, and described three hydraulic jacks 3 are arranged along the horizontal direction of described workbench 2.Same as described above, when hydraulic jack 3 is three, also the longitudinal direction of three hydraulic jacks 3 along described workbench 2 can be arranged.
Further, as shown in Figure 1, in order to the stroke of accurate hydraulic control oil cylinder 3, frame 1 is connected with the position sensor 4 of the position of the push rod detecting described hydraulic jack 3, the output of position sensor 4 is electrically connected with the controller of described hydraulic jack 3, position sensor 4 can be many groups, respectively each hydraulic jack 3 corresponding.
