Abstract
The invention relates to a large-tonnage pillar press which comprises a lower cross beam, stand columns, sliding blocks, hydraulic cylinders and an upper cross beam. The stand columns are evenly distributed at the four corners of the lower cross beam and the four corners of the upper cross beam. The sliding blocks are arranged on the stand columns between the lower cross beam and the upper cross beam in a penetrating mode. The large-tonnage pillar press is characterized in that the hydraulic cylinders are evenly arranged at the lower end of the upper cross beam, and the ends of piston rods of the hydraulic cylinders are fixed to the upper ends of the sliding blocks. The large-tonnage pillar press has the beneficial effects that the hydraulic cylinders are evenly arranged at the lower end of the upper cross beam, and pressure is large and uniform. The hydraulic cylinders are communicated with connecting pipes so that rapid oil supply can be achieved, the sliding blocks are pushed to rapidly move downwards, and work efficiency is improved.
Description
technical field:
The present invention relates to a kind of large-tonnage pillar press, belong to hydraulic machinery manufacturing technology field.
background technology:
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.Traditional hydraulic press pressure is less, and not fast, the speed of service is slow.
summary of the invention:
The object of this invention is to provide a kind of operating efficiency high, pressure uniform, there is the large-tonnage pillar press of quick function.
For achieving the above object, the technical solution used in the present invention is:
A kind of large-tonnage pillar press, comprise sill, column, slide block, hydraulic cylinder and entablature, column is installed the corner of sill and entablature is uniform, column between sill and entablature is coated with slide block, be characterized in: evenly install several hydraulic cylinder in the lower end of entablature, the termination of the piston rod of hydraulic cylinder is fixed on the upper end of slide block.
Described hydraulic cylinder comprises cylinder body, piston, piston rod, termination, is provided with fuel feed hole in the center of cylinder body upper end cover.
Be provided with the vertical core identical with hydraulic cylinder number between the upper surface of described entablature and lower surface, in each vertical core, be provided with tube connector, the upper end of tube connector is provided with prefill valve, and the lower end of tube connector is connected with hydraulic cylinder by the fuel feed hole of cylinder body upper end.
The invention has the beneficial effects as follows: evenly install several hydraulic cylinder in the lower end of entablature, pressure is large, pressure uniform.Hydraulic cylinder is connected with tube connector, can realize quick fuel feeding, promotes slide block and runs downwards fast, increase work efficiency.
accompanying drawing illustrates:
Fig. 1 is structural representation of the present invention.
In figure: 1 sill, 2 columns, 3 slide blocks, 4 hydraulic cylinders, 5 entablatures, 6 prefill valves, 7 tube connectors.
detailed description of the invention:
Below in conjunction with drawings and Examples, the present invention is further described.
As shown in Figure 1, a kind of large-tonnage pillar press, comprise sill (1), column (2), slide block (3), hydraulic cylinder (4) and entablature (5), column (2) is installed the corner of sill (1) and entablature (5) is uniform, column (2) between sill (1) and entablature (5) is coated with slide block (3), be characterized in: evenly install several hydraulic cylinder (4) in the lower end of entablature (5), the termination of the piston rod of hydraulic cylinder (4) is fixed on the upper end of slide block (3).Hydraulic cylinder (4) comprises cylinder body, piston, piston rod, termination, fuel feed hole is provided with in the center of cylinder body upper end cover, be provided with the epicoele oil pipe be connected with cylinder body upper chamber on the top of cylinder body, be provided with the lower cavity oil pipe be connected with lower cavity in the bottom of cylinder body.The vertical core identical with hydraulic cylinder (4) number is provided with between the upper surface of entablature (5) and lower surface, tube connector (7) is provided with in each vertical core, the upper end of tube connector (7) is provided with prefill valve (6), and the lower end of tube connector (7) is connected with hydraulic cylinder (4) by the fuel feed hole of cylinder body upper end.
Operation principle: during work, hydraulic oil, from fuel feed hole and oil inlet pipe simultaneously to hydraulic cylinder (4) fuel feeding, promotes slide block (3) fast and moves downward, process workpiece.Several hydraulic cylinder (4) is evenly installed in the lower end of entablature (5), and pressure is large, pressure uniform.Hydraulic cylinder (4) is connected with tube connector (7), can realize quick fuel feeding, promotes slide block (3) and runs downwards fast, increase work efficiency.
Claims (2)
