Abstract
The utility model relates to a forming hydraulic press for a large-tonnage stainless steel bellows expansion joint, comprising a worktable, an upper beam, upright columns, a piston cylinder and plunger cylinders, wherein the worktable is fixedly connected with the upper beam above the worktable through the upright columns at four corners, the piston cylinder is arranged at the center of the upper beam, four plunger cylinders are distributed all round the upper beam, and a circular pressure head which is fixedly connected with the piston cylinder and the plunger cylinders is arranged below a lower beam, therefore the downward synchronism of the piston cylinder and the plunger cylinders is improved, the pressure of the pressure head on various points of a steel pipe is uniform in pressing, and the pressing quality and stability are improved. Meanwhile, a water pipe is arranged in the pressure head, the high pressure water can enter the steel pipe through the water pipe in pressing, various types of molds are unnecessarily connected with a water source, and the use is convenient.
Description
Technical field
The utility model relates to a kind of large-tonnage corrugated stainless steel tubing telescopic joint forming hydraulic press, comprise workbench, upper beam, column, piston cylinder and plunger case, described workbench is fixedlyed connected with the upper beam of its top by four jiaos column, piston cylinder is equipped with at the center of described upper beam, is distributed with four plunger cases all around.
Background technology
Along with China's industrial infrastructure, traffic infrastructure construction and fast development of urbanization, also more and more higher to the needs of the bellows of various models.The hydraulic cylinder of traditional bellows hydraulic press comprises piston cylinder and increases the plunger case of press power that it directly at the end face fixation steel plate of piston cylinder and plunger case, uses steel plate to contact with the steel pipe that needs compacting and suppress when carrying out the compacting of bellows.Because the anti-deformation insufficient strength of steel plate, and there be the asynchronous of trace in piston cylinder and plunger case when descending, and the unbalance stress of each pressure spot of bellows when easily causing suppressing has influenced the quality of bellows, can not guarantee to suppress quality of stability.
The utility model content
The technical problems to be solved in the utility model provides a kind of large-tonnage corrugated stainless steel tubing telescopic joint forming hydraulic press, can guarantee the DL synchronization of piston cylinder and plunger case, improves the compacting quality.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of large-tonnage corrugated stainless steel tubing telescopic joint forming hydraulic press, comprise workbench, put the beams in place, column, piston cylinder and plunger case, described workbench is fixedlyed connected with the upper beam of its top by four jiaos column, piston cylinder is equipped with at the center of described upper beam, be distributed with four plunger cases all around, its innovative point is: the below of described underbeam is provided with the spherical head of fixedlying connected with plunger case with piston cylinder, the inside of described pressure head has water lines, the water inlet of described water lines is opened the sidewall at pressure head, and delivery port is positioned at the center of pressure head lower surface.
Advantage of the present utility model is: spherical head is fixedlyed connected with piston cylinder, plunger case, has improved piston cylinder, the descending synchronism of plunger case, and pressure head is even to each point pressure of steel pipe when making compacting, has improved compacting quality and stability.Pressure head inside be provided with can with steel pipe water pipe connecting road to be pressed, during compacting, water under high pressure can need not to insert the water source on the mould of various models in water lines enters steel pipe, and is easy to use.
Description of drawings
Accompanying drawing is the structural representation of large-tonnage corrugated stainless steel tubing telescopic joint forming hydraulic press of the present utility model.
The specific embodiment
As shown in drawings, comprise workbench 1, upper beam 2, column 3, piston cylinder 4, plunger case 5, pressure head 6, water lines 7.
Above-mentioned workbench 1 is fixedlyed connected with the upper beam 2 of its top by four jiaos column 3, and piston cylinder 4 is equipped with at the center of this upper beam 2, is distributed with four plunger cases 5 that are used to increase press power around piston cylinder 4.Be provided with the thicker large tracts of land spherical head 6 of thickness above workbench 1, this pressure head 6 is fixedlyed connected with piston cylinder 4, plunger case 5.The mould that steel pipe to be pressed is housed is placed on the workbench 1, when piston cylinder 4 and plunger case 5 promotes 6 pairs of moulds of pressure heads and carries out punching press, because pressure head 6 is fixedlyed connected with piston cylinder 4, plunger case 5, piston cylinder 4 and plunger case 5 are accomplished DL synchronization, the pressure of pressure head each point is identical, and like this, steel pipe is stressed evenly, guarantee the compacting quality, improved the stability of compacting.
Be provided with water lines 7 in the above-mentioned pressure head, the water inlet 8 of this water lines 7 is opened the sidewall at pressure head, delivery port 9 is located at the center of pressure head lower surface, during compacting, high-pressure water can enter in the steel pipe through water lines 7, need not on the bellows mould of various models, set up waterpipe jointing, easy to use, reduced cost.
