The purpose of the utility model is realized in the following way: the hydraulic press comprises a hydraulic press body, wherein a movable cross beam of the hydraulic press body is provided with a main oil cylinder, the main oil cylinder is connected with an upper sliding block, the upper sliding block is provided with a first oil cylinder, and the first oil cylinder is connected with an upper ejector rod; the fixed beam is provided with a second oil cylinder, the second oil cylinder is connected with a supporting plate, and the supporting plate is connected with a lower ejector rod.
Further, a water cooling plate is arranged on the bottom surface of the upper sliding block and connected with the heating platform; a water cooling plate is arranged on the fixed cross beam, and a heating platform is arranged on the water cooling plate.
Further, a heating pipe is arranged in the heating platform.
The utility model has the beneficial effects that: the upper sliding block of the main oil cylinder of the hydraulic machine body is provided with a first oil cylinder, and the upper ejector rod is driven by the first oil cylinder; the fixed cross beam is provided with a second oil cylinder, the lower ejector rod is driven by the supporting plate, the ejector rods are arranged in two directions, the stretching operation in the forward direction and the reverse direction can be realized aiming at different processing parts, and the design and the installation form of the die are flexible and changeable.
Description of the drawings:
FIG. 1 is a schematic diagram of a bi-directional hydraulic apparatus with a ram according to the present utility model.
Detailed Description
The present embodiment will be further described with reference to the accompanying drawings
As can be seen from fig. 1, the hydraulic press comprises a hydraulic press body, wherein a movable cross beam 12 of the hydraulic press body is provided with a main oil cylinder 1, the main oil cylinder 1 is connected with an upper sliding block 3, the upper sliding block 3 is provided with a first oil cylinder 2, and the first oil cylinder 2 is connected with an upper ejector rod 6; the fixed cross beam 11 is provided with a second oil cylinder 10, the second oil cylinder 10 is connected with the supporting plate 9, and the supporting plate 9 is connected with the lower ejector rod 8. The ejector rods are arranged vertically and vertically in the utility model, so that the forward and backward stretching operation can be realized, the conventional hydraulic equipment can only stretch reversely, the deep-drawing part processing is not suitable, and after the ejector rods are additionally arranged, the forward stretching operation can be realized, and the deep-drawing part processing is especially suitable for the part stretching processing with larger depth.
The bottom surface of the upper sliding block 3 is provided with a water cooling plate 4, and the water cooling plate 4 is connected with a heating platform 5; a water cooling plate 4 is arranged on the fixed cross beam 11, and a heating platform 5 is arranged on the water cooling plate 4. A heating pipe 7 is arranged in the heating platform 5. Considering that part of the materials are brittle, the problems of cracking and the like easily occur in the stretching process, the heating platform is additionally arranged, and the problem of hydraulic devices occurs due to the fact that heat is transferred to other parts through the water cooling plate, the heating platform can realize hot stretching of parts, and the yield is improved.
