Abstract
Disclosed is a hydraulic press which comprises a frame(2), an operation platform and a cylinder(8),wherein the cylinder is provided with a piston push rod(3) inside. The utility model is mainly characterized in that a tension cylinder(6) is arranged on the cylinder(8); the piston push rod(3 inside the cylinder(8) is hollow; the piston push rod(7) inside the tension cylinder(6) passes through the hollow part of the piston push rod(3) inside the cylinder(8). The utility model uses piston rods with two or even more rods to push and pull the metal plates so as to mold the plates at one time. The utility model is of scientific structure and simple and convenient operation. The hydraulic press based on the technique proposal of the utility model is a great breakthrough of the metal plate tension equipment in the metal plate industry, particularly the automobile manufacturing industry, and will definitely bring good effects to the metal hydraulic press industry.
Description
Technical field: the utility model is about a kind of improvement of hydraulic press invention, particularly be of the improvement invention of a kind of metallic plate drawing and forming with hydraulic press, what be specifically related to is a kind of invention of multi-cylinder hydraulic press.
Background technology: in the prior art, hydraulic press generally all is made up of frame, operating platform and oil cylinder, be mainly used in the metallic plate drawing and forming, its primary structure is to be provided with piston push rod in oil cylinder, at the end of push rod installation mold, when metallic plate is stretched, can not finish with a working cycles, need repeatedly die change punching press, its troublesome poeration, inefficiency.
Summary of the invention: in view of the problem that known technology exists, the purpose of this utility model aims to provide a kind of scientific structure, and is simple to operation, and high efficiency can once be finished the hydraulic press of drawing and forming.For achieving the above object, the utility model is finished as follows: this hydraulic press comprises frame, operating platform and oil cylinder, be provided with piston push rod in the described oil cylinder, it is characterized in that being provided with above the described oil cylinder stretching oil cylinder, the piston push rod of described oil cylinder is a ducted body, and the in-oil cylinder piston push rod of described stretching is along the hollow part of axis by the oil cylinder piston push rod; Described oil cylinder is symmetrical up and down on vertical cylinder by the oil cylinder group that two oil cylinders are formed at least; The oil cylinder group that also can be at least form by two oil cylinders on horizontal (double action) oil hydraulic before and after symmetry; Described operating platform is movably arranged on the frame.The utility model is provided with the stretching oil cylinder above oil cylinder, and piston push rod that should the stretching oil cylinder is by the hollow part of hollow piston push rod, greatly increased the punching precision of piston push rod, and only need an operation the metallic plate drawing and forming, it is simple in structure, easy to operate, compare with known technology, have substantive distinguishing features and progress.
Description of drawings: the utility model has following accompanying drawing:
Fig. 1 is a structural representation of the present utility model.
The specific embodiment: accompanying drawing has been represented structure of the present utility model and embodiment, further describes the relevant details of embodiment below more in conjunction with the accompanying drawings.This hydraulic press includes frame 2, operating platform 1 and oil cylinder 8, be provided with piston push rod 3 in the described oil cylinder 8, this piston push rod 3 is a ducted body, be provided with stretching oil cylinder 6 above the described oil cylinder 8, piston push rod 7 in the described stretching oil cylinder 6 is by the hollow part of oil cylinder 8 piston push rods 3, in the above-mentioned oil cylinder piston push rod piston push rod of at least one can be installed step by step, but on oil cylinder, to increase corresponding stretching oil cylinder simultaneously, present embodiment is installed a piston push rod 7 in oil cylinder 8 piston push rods 3 hollow parts, the also i.e. corresponding stretching oil cylinder 6 of increase on oil cylinder 8, the mould that moulding is used is installed in the end of hollow piston push rod 3 and piston push rod 7, the oil cylinder group that these two oil cylinders are formed is symmetrical up and down on vertical hydraulic press, symmetry before and after also can be on horizontal (double action) oil hydraulic, the utility model adopts symmetry up and down, described operating platform 1 is movably arranged on the frame 2, also also is that this operating platform 1 can be regulated.When the utility model is worked, metallic plate and finished product carry out feeding and finished product output from operating platform automatically, 4 pairs of oil cylinder 8 fuel feeding of hydraulic oil pipe at first, piston push rod 3 pressurizeds also glide, and the metallic plate on the operating platform 1 is carried out stretching the first time, and the piston push rod of below symmetry glides simultaneously, at this moment, oil pipe 5 is open-minded, and piston push rod 7 stressed and downslides are carried out stretching the second time to the metallic plate on the operating platform 1; When hollow piston push rod 3 and piston push rod 7 press down put in place after, the mould of its piston push rod end carries out blank holder to the metallic plate on the operating platform 1; Last oil cylinder work by the below symmetry, its operation principle is identical with the principle of above-mentioned stretching, metallic plate on the operating platform is stretched and moulding for the third time, then, laterally zygomorphic hollow piston push rod 3 moves upward simultaneously, piston push rod 7 move toward one another of symmetry are carried out the demoulding simultaneously to the mould of piston push rod end, finish stretching and moulding like this with a procedure.The utility model has prior art to compare, and has substantive distinguishing features and progress.
