Abstract
The utility model discloses an elliptical manhole ring forming device, which comprises a bottom plate. Two guide shafts are mounted vertically on the bottom plate, a lower molding bed capable of sliding vertically along the two guide shafts are sleeved on the guide shafts, an upper molding bed are fixed to the upper portions of the two guide shafts, the upper molding bed and the lower molding bed are matched with each other to form an elliptical manhole core, a hydraulic cylinder is mounted on the bottom plate right below the lower molding bed, and the bottom face of the lower molding bed is supported by the upper end of a telescopic rod of the hydraulic cylinder. Since the upper molding bed and the lower molding bed are matched with each other to form the elliptical manhole core, a pressed elliptical manhole ring is strictly elliptical and has higher quality, and the method of using the hydraulic cylinder as power for pressing the elliptical manhole ring as compared with the existing manual processing is timesaving and laborsaving and higher in efficiency.
Description
Technical field
The utility model relates to a kind of mould, relates in particular to a kind of oval manhole circle shaped device.
Background technology
Oval manhole circle is common a kind of structural shape during special equipment such as boilers and pressure vessel is made, and is characterized in that low cost of manufacture, overhaul of the equipments are convenient.Present most manufactory adopts the pit furnace heating more, manually bends, or arbitrarily suppress with jack after rolling into cylinder the processing method of oval manhole circle, though can reach practical effect, but the physical dimension after the moulding is difficult to guarantee that presentation quality is poor that production efficiency is low.
The utility model content
The purpose of this utility model is to provide the oval manhole circle shaped device that a kind of quality of production is good, production efficiency is high.
For achieving the above object, the utility model provides a kind of oval manhole circle shaped device, comprise base plate, two axis of guides are installed on the vertical direction on the described base plate, being with on two described axis of guides can be along its following fetal membrane that slides up and down, two described axis of guide tops are fixed with fetal membrane, the described fetal membrane of going up cooperates the oval manhole core of formation with described fetal membrane down, on the base plate under the described fetal membrane down hydraulic cylinder is installed, the upper end of the expansion link of described hydraulic cylinder supports the described bottom surface of fetal membrane down.
Oval manhole circle shaped device of the present utility model, the top of each described axis of guide is provided with a fixing lug boss, and described both sides of going up fetal membrane are stuck on the described fixing lug boss and by nut to be fixed.
Oval manhole circle shaped device of the present utility model, the bottom of each described axis of guide are provided with strengthens the reinforcement gusset that is connected between the fixing described axis of guide and the described base plate.
Oval manhole circle shaped device of the present utility model, comprise base plate, two axis of guides are installed on the vertical direction on the base plate, being with on two axis of guides can be along its following fetal membrane that slides up and down, two axis of guide tops are fixed with fetal membrane, last fetal membrane cooperates the oval manhole core of formation with following fetal membrane, on the base plate under the following fetal membrane hydraulic cylinder is installed, and the upper end of the expansion link of hydraulic cylinder supports the described bottom surface of fetal membrane down.During use, oval manhole circle semi-finished product are rolled into circular cylinder body, hydraulic cylinder is dropped to extreme lower position, put circular cylinder body on following loose tool, the primer fluid cylinder pressure, the expansion link of hydraulic cylinder promotes down, and fetal membrane rises, until fetal membrane and last loose tool match down, thereby the oval manhole circle of moulding, form oval manhole core because last fetal membrane cooperates with following fetal membrane, the oval manhole circle that suppresses like this is strict ellipse, and its quality is higher, and hydraulic cylinder to suppress oval manhole circle as power more time saving and energy saving than existing artificial compacting, efficient is higher.

Fig. 2 looks the partial structurtes cutaway view for the left side of oval manhole circle shaped device among Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in detail:
With reference to illustrated in figures 1 and 2, the oval manhole circle shaped device of present embodiment, comprise base plate 2, be welded with two axis of guides 4 on the base plate 2 on the vertical direction, the bottom of each axis of guide 4 is provided with four along the equally distributed reinforcement gusset 3 of the axis of guide 4 peripheries, is connected between fixed guide axle 4 and the base plate 2 strengthening.Being with one on two axis of guides 4 can be along its following fetal membrane 5 that slides up and down.Two axis of guide 4 tops are fixed with fetal membrane 7, and the top of each axis of guide 4 is provided with a fixing lug boss 9, and the both sides of last fetal membrane 7 are stuck on the fixing lug boss 9 and by nut 8 and fix.Last fetal membrane 7 cooperates the oval manhole core of formation with following fetal membrane 5, on the base plate 2 under the following fetal membrane 5 hydraulic cylinder 1 is installed, and the upper end of the expansion link of hydraulic cylinder 1 supports down the bottom surface of fetal membrane 5.
During use, the base plate 2 of the oval manhole circle shaped device of present embodiment need be fixed on the operating platform of certain altitude, so that operation, semi-finished product with oval manhole circle 6 roll into circular cylinder body earlier, and hydraulic cylinder 1 is dropped to extreme lower position, put circular cylinder body on following loose tool 5, primer fluid cylinder pressure 1, the expansion link of hydraulic cylinder 1 promotes fetal membrane 5 risings down, until fetal membrane 5 and last loose tool 7 match the static purpose that can reach the moulding of oval manhole circle in 5 minutes down.
Above embodiment is described preferred implementation of the present utility model; be not that scope of the present utility model is limited; under the prerequisite that does not break away from the utility model design spirit; various distortion and improvement that the common engineers and technicians in this area make the technical solution of the utility model all should fall in the definite protection domain of claims of the present utility model.
