Abstract
The utility model relates to a four-column braced structure of a hydraulic press bench, wherein the lift-up cylinder contact surface of the hydraulic press lower beam is provided with at least four sets of bracing columns, each set of bracing columns consist of an upper bracing column and a lower bracing column, the upper bracing column is fixedly connected with a movable bench of the hydraulic press, the lower bracing column is connected and fixed on the lower beam and the contact surface of the lower beam lift-up cylinder, an interval is provided between the upper bracing column and the lower bracing column, and the hydraulic cushion which is connected with the lower beam lift-up cylinder is provided with a guide hole which has a larger diameter than the diameter of the upper bracing column or the lower bracing column. The utility model has the advantages that the thickness of upper surface plate of the hydraulic movable bench can be reduced, the materials are saved, the manufacturing cost is reduced, the intensity and the accuracy of the machine are guaranteed, and the structure has a brighter prospect development prospect.
Description
Technical field
The wood utility model belongs to the press technologies field, particularly relates to a kind of hydraulic press working strength that increases, the hydraulic press workbench four post supporting constructions of economical with materials and reduction manufacturing cost.
Background technology
In general hydraulic press, its workbench is divided into hydraulic die cushion and two kinds of structures of no hydraulic die cushion, and the stressed of the hydraulic press workbench of no hydraulic die cushion mainly is to come the support works deck plate by the gusset under the workbench, makes it stressed with whole underbeam integral body, distortion; In having the hydraulic press of hydraulic die cushion, because worktable panel has hydraulic die cushion to move up and down, and general hydraulic die cushion takes up room very big, therefore can't bearing rib be installed again supports, the main pressure of hydraulic press all is pressed on the worktable panel, at this moment, panel will bear full tonnage pressure status, and also bigger distortion will take place in the middle, the Thickness Design of panel need satisfy shear stress and the bending stress that can bear full tonnage in its cross section like this, for the intensity that guarantees panel with prevent to be out of shape and what adopt all is panel constructions of thickening, especially at large-tonnage, in the hydraulic press of big table top, its panel weight has accounted for complete machine gross weight quite great proportion, so caused manufacturing cost to increase considerably, has also wasted material simultaneously.
Summary of the invention
The utility model provides a kind of hydraulic press working strength that increases for solving the technical problem that exists in the known technology, the hydraulic press workbench four post supporting constructions of economical with materials and reduction manufacturing cost.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is:
Hydraulic press workbench four post supporting constructions, it is characterized in that: on hydraulic press underbeam liftout tank contact-making surface, be provided with four groups of support columns at least, each is organized support column and is divided into upper support post and lower support post again, wherein upper support post and movable workbench of hydraulic press are connected and fixed, the lower support post is fastened on underbeam and the underbeam liftout tank contact-making surface, between upper support post and lower support post, be provided with certain clearance, with the pilot hole that has on the hydraulic die cushion that the underbeam liftout tank is connected greater than upper support post and lower support column diameter.
The utility model can also adopt following technical measures:
The δ value in gap is between the 0.3-0.6mm between upper support post and the lower support post.
Advantage and the good effect that the utlity model has are: because the utility model is equipped with support column on the contact-making surface of hydraulic press underbeam liftout tank, when the movable workbench of hydraulic press top panel is out of shape under pressured state, and when deflection reaches the gap width of upper support post and lower support intercolumniation, upper support post and lower support post begin the stress that is squeezed, share fractional load, support column not only passes to fractional load on the underbeam like this, shared the stressed of travelling table, but also can control the deflection of travelling table top panel, under the prerequisite of same required precision and requirement of strength, can greatly reduce the thickness of movable workbench of hydraulic press top panel, not only save material, reduced manufacturing cost, can also guarantee simultaneously the intensity and the machining accuracy of machine, so this structure has comparatively vast potential for future development.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the schematic layout pattern of the utility model underbeam liftout tank contact-making surface and support column.
Among the figure: 1 travelling table, 2 upper support posts, 3 hydraulic die cushions, 4 underbeam liftout tank contact-making surfaces, 5 underbeams, 6 lower support posts, 7 hydraulic die cushion pilot holes, 8 underbeam liftout tanks.
The specific embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
See also Fig. 1 and Fig. 2, hydraulic press workbench four post supporting constructions, on hydraulic press underbeam liftout tank contact-making surface 4, be provided with four groups of support columns at least, each is organized support column and is divided into upper support post 2 and lower support post 6 again, wherein upper support post 2 is connected and fixed with movable workbench of hydraulic press 1, lower support post 6 is fastened on underbeam and the underbeam liftout tank contact-making surface 4, between upper support post and lower support post, be provided with certain clearance, the δ value in gap is according to the position of support column between upper support post and the lower support post, the diameter of support column and the relevant parameter of travelling table are set, and the δ value in the present embodiment is set at 0.3-0.6mm.When avoiding hydraulic die cushion to move up and down and support column interfere, and have the hydraulic die cushion pilot hole 7 that is slightly larger than upper support post and lower support column diameter on the hydraulic die cushion 3 that underbeam liftout tank 8 is connected, underbeam 5 is fixed on the ground.For adapting to the hydraulic press of various different tonnages and varying mesa, the position that described support column is arranged also can be inequality, and therefore the gap delta value of corresponding support column is also different, can guarantee under the prerequisite that the motion of processing and travelling table is not interfered, the gap is big more, and the pressure of being shared is just more little.
Operation principle of the present utility model is:
When the movable workbench of hydraulic press top panel deforms under pressured state, and when deflection reaches the δ value, each is organized support column and begins the stress that is squeezed, and share the fractional load of hydraulic press, support column not only is delivered to fractional load on the hydraulic press underbeam like this, shared stressedly, but also controlled the deflection of travelling table top panel.
Claims (2)
