Detailed Description
The technical solution of the present invention will be described in detail below with reference to the accompanying drawings.
Fig. 1 to 3 show a first embodiment of the present invention. As shown in FIG. 1, the hot working apparatus of the present invention includes a heating furnace housing 107 and a ram. Wherein the ram includes a hydraulic tube 105 and a ram body 108. The hydraulic tube 105 is a hollow tubular structure, and one end of the hydraulic tube 105 is connected to the ram body 108. The ram body 108 is disposed in the furnace casing 107. A through hole is provided in the heating furnace casing 107 to pass the hydraulic pipe 105. The other end of the hydraulic pipe 105 is disposed outside the heating furnace casing 107 and connected to the hydraulic mechanism, so that the hydraulic pipe 105 can drive the head body 108 in the vertical direction shown in fig. 1 by the power from the hydraulic mechanism. In order to maintain the temperature and the environment inside the furnace casing 107, a seal pressing kit 102 is provided between the hydraulic pipe 105 and the furnace casing 107.
Fig. 2 shows the structure of the hot working apparatus shown in fig. 1 from the right side angle shown in fig. 1, and fig. 3 further shows a cross-sectional view of the hot working apparatus from the perspective shown in fig. 2. As can be seen from fig. 1 to 3, a ram heating cable connecting ram body interface 101 and a ram cooling medium channel connecting ram body interface 106 are arranged on the hydraulic pipe 105 on the inner part of the heating furnace shell 107; the hydraulic pipe 105 is provided with a head heating cable external interface 104 and a head cooling medium channel external interface 103 on the outer part of the heating furnace shell 107. Between the ram heating cable connection ram body interface 101 and the ram heating cable external interface 104 is a ram heating cable channel disposed within the hollow space of the hydraulic tube 105. The cable of the heating part 201 in the connection pressure head body 108 is arranged in the pressure head heating cable channel, and is connected with the heating part 201 through the pressure head heating cable connection pressure head body interface 101, and is connected with the external power supply through the pressure head heating cable external interface 104. Between the ram cooling medium channel connection ram body interface 106 and the ram cooling medium channel external interface 103 is a ram cooling medium channel disposed within the hollow space of the hydraulic tube 105. The cooling medium enters the head cooling medium channel from the source through the head cooling medium channel external connection interface 103 on the right side in fig. 3, and then enters the cooling medium cavity 302 in the head body 108 through the head cooling medium channel connection head body interface 106 on the right side in fig. 3 to cool the head body 108. The cooling medium then returns to the ram cooling medium channel through the ram cooling medium channel connection ram body interface 304 on the left in fig. 3, and finally flows out of the ram cooling medium channel external interface 305 on the left in fig. 3. In fig. 3, the two head coolant channels are not shown to and from for clarity, but are shown with arrowed lines to indicate the direction of coolant flow. When flowing through the hydraulic pipe 105, the cooling medium also cools the cable in the pressure head heating cable channel, so that accident potential caused by overheating of the cable due to electrification is avoided. In the present embodiment, the cooling medium is a liquid cooling medium. Meanwhile, a plurality of through holes do not need to be formed in the heating furnace shell 107, and the radial size of the through hole through which the hydraulic tube 105 passes only needs to be slightly enlarged, so that the manufacturing cost is reduced, and the possibility of leakage is also reduced. Fig. 3 shows the internal structure of the seal pressing sleeve 102, and two pressing inner and outer ring assemblies arranged by the outer ring of the hydraulic pipe 105 constitute the seal pressing sleeve 102. A V-ring 301 is provided between the two said components, wherein the inner ring component presses the V-ring 301 against the furnace shell 107. The V-shaped seal ring 301 is a seal ring having a V-shaped cross section, and has a better sealing effect than a conventional seal ring having a rectangular cross section.
