Embodiment Construction
[0021] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and implementation examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0022] Please also refer to figure 1 , figure 2 , image 3 and Figure 4 , The self-moving nozzle correction hydraulic machine provided by the preferred embodiment of the present invention includes a body 1, a special-shaped indenter 6, a driver, a translation unit, and a lifting unit.
[0023] The special-shaped indenter 6 is installed on the body 1, and the driver drives the special-shaped indenter 6 to work. In this implementation example, the driver is a compact combination cylinder 2, please combine figure 2 , the fuselage 1 is connected to the compact combination cylinder 2...

The invention discloses a self-moving nozzle correction hydraulic machine, which comprises a body, a special-shaped pressure head installed on the body, a driver for driving the special-shaped pressure head to work, a translation unit for driving the body to move horizontally and laterally, and a drive body Lifting unit that moves vertically and longitudinally. The translation unit includes a pair of guide rails parallel to each other with V-shaped guide surfaces, at least three rollers with V-shaped rolling surfaces, and a screw drive device. The lifting unit includes a synchronous lifting mechanism and a separate hydraulic control system. According to the principle of at least three points to determine a plane, the rollers are divided into two groups and installed on the bottom of the fuselage respectively. The rollers are installed on the pair of guide rails and the V-shaped rolling surface is matched with the V-shaped guide surface of the corresponding guide rail to reciprocate on the V-shaped surface. The mating surface of the friction motion pair formed by the roller surface and the V-shaped guide surface. The screw driving device drives the rollers to move along the guide rail to drive the body to translate. The synchronous lifting mechanism is installed at the bottom of the body to lift the body. The separate hydraulic control system is fixed on the body to drive the synchronous lifting mechanism.
Description
technical field [0001] The invention relates to a hydraulic machine, in particular to a self-moving nozzle correction hydraulic machine. Background technique [0002] Large-diameter long steel pipes (10-25 meters) will appear horn-shaped nozzles or oval nozzles after deep-drawing and hot forging processes. At present, domestic manufacturers mostly use fixed-type calibration hydraulic presses for calibration. Since the tonnage of the workpiece is generally about 20-50 tons, the cost of moving and rotating is high, the efficiency is very low, and the processing risk factor is large. [0003] Therefore, it is necessary to develop a self-moving nozzle correction hydraulic machine, which can move freely in four degrees of freedom according to the size of the workpiece and the height of the corresponding rotation center, so as to adapt to the roundness correction of different workpieces. Contents of the invention [0004] In view of this, the present invention provides a self-m...
