The utility model discloses prestressed structure frame is split type structure, and for overall structure frame, its each part manufacturing is easy, and the assembly is simple, is convenient for change, and stand (2) are in the pressurized state all the time in the work, and pull rod (5) are in the state of drawing all the time, and the stress is good, has improved the rigidity of frame, long service life.
Description
Technical field
The utility model relates to a kind of structural framing that is applicable to the heavy duty metal processing equipment, particularly relates to a kind of prestressed structure framework that is applicable to hydraulic press.
Background technology
At present, the framework of hydraulic press use has two kinds of forms: general frame and local prestressed frame.General frame is that monoblock cast forms, is used on the small-sized hydraulic machine more, and the machined difficulty, in case defective appears in the part, whole framework just can not use, and is uneconomical; Local prestressed frame is a split-type structural, entablature, sill and column be casting and machined separately, column is a column structure, two ends are cylindrical and are processed with screw thread, during assembling, the end of two root posts are inserted respectively in the installing space at upper and lower crossbeam two ends, pass through nut screwing clamping, only produce local prestressing force by heating, make frame stiffness improve, but install operation process is more loaded down with trivial details at the two ends of column.
Defective in view of above-mentioned two kinds of frame structure forms existence, the design people is based on being engaged in this type of product design manufacturing abundant for many years practical experience and professional knowledge, and cooperates the utilization of scientific principle, actively studied innovation, in the hope of founding a kind of framework of new structure, make it have more practicality.
Summary of the invention
The purpose of this utility model is, overcomes the defective that existing general frame and local prestressed frame exist, and the prestressed structure that a kind of rigidity is big, stress is good framework is provided.Technical problem to be solved is that the each several part of nonintegrated structure framework all is under the pretightning force effect, improves frame stiffness, and makes framework each several part stress good, thereby be suitable for practicality more.
The purpose of this utility model and to solve its technical problem be to adopt following technical scheme to realize.According to the prestressed structure framework that the utility model proposes, it comprises entablature, column and sill, also be provided with two ends in the prestressed frame and process threaded pull bar and pre-load nut, described pull bar passes described entablature, column and sill, and the two ends of described pull bar are fixed as one described entablature, column and sill connection with pre-load nut respectively.
The purpose of this utility model and solve its technical problem and also adopt following technical measures further to realize.
Aforesaid prestressed frame, wherein said column is a hollow structure.
Aforesaid prestressed frame is provided with 1～8 pull bar in wherein said each column.
The utility model compared with prior art has tangible advantage and beneficial effect.By above technical scheme as can be known, the utility model prestressed frame has following advantage at least:
1. prestressed frame of the present utility model adopts split-type structural, and entablature, column, sill are cast separately, is convenient to processing.In case and defective appears in the part, can only change defective FRU, and is economical and practical.
2. prestressed frame of the present utility model adopts the column of hollow structure, uses pull bar and pre-load nut that entablature, column, sill are formed framework, and consumable material is few, and is in light weight, and assembly manipulation is simple.
3. prestressed frame column of the present utility model is in pressured state all the time, and pull bar is in tension state all the time, has improved the rigidity of framework, has prolonged service life.
In sum, prestressed structure framework of the present utility model is with respect to the overall structure framework, its each component processing is easy to manufacture, assembling is simple, is convenient to change, and makes column be in pressured state all the time at work, pull bar is in tension state all the time, stress is good, has improved the rigidity of framework, thereby has prolonged service life.It has above-mentioned many advantages and practical value, and in like product, do not see have similar structural design to publish or use and really belong to innovation, no matter it all has bigger improvement on product structure or function, have large improvement technically, and produced handy and practical effect, and the framework that more existing hydraulic press uses has the multinomial effect of enhancement, thereby is suitable for practicality more, really is a new and innovative, progressive, practical new design.
Above-mentioned explanation only is the summary of technical solutions of the utility model, for can clearer understanding technological means of the present utility model, and can be implemented according to the content of specification, and for above-mentioned and other purposes, feature and advantage of the present utility model can be become apparent, below especially exemplified by preferred embodiment, and conjunction with figs., be described in detail as follows.
Description of drawings
Fig. 1 is a prestressed structure framework overall construction drawing of the present utility model.
Fig. 2 is the cutaway view of the A-A of column shown in Fig. 1 section.
The specific embodiment
For further setting forth the utility model is to reach technological means and the effect that predetermined goal of the invention is taked, below in conjunction with accompanying drawing, to structure, feature and effect thereof according to the prestressed frame that the utility model proposes, describe in detail as after.
See also illustrated in figures 1 and 2.The preferred embodiment of the utility model prestressed frame, it mainly comprises entablature 1, column 2, sill 3, entablature 1, column 2, sill 3 all are castings separately and process.Column 2 has adopted hollow structure, and pull bar 5 makes entablature 1, column 2, sill 3 form closed frame for elongated structure, two ends are processed with screw thread and special pre-load nut 4 actings in conjunction.This structure is installed simple, and whole framework make column 2 be in pressured state all the time, and pull bar 5 is in tension state all the time under the effect of pull bar 5 and pre-load nut 4, get prestress value usually and be forging force 1.6 times, has improved the rigidity of framework.The quantity of column 2 can be 2 or more, also intermediate transverse girder can be set as required, and the quantity of pull bar 5 also can be different in every root post 2, are 1～8, take various arrangement in column.Be provided with 5 pull bars 5 in the present embodiment in each column 2.
The above, it only is preferred embodiment of the present utility model, be not that utility model is done any pro forma restriction, though the utility model discloses as above with preferred embodiment, yet be not in order to limit the utility model, any those skilled in the art are not in breaking away from the technical solutions of the utility model scope, when the technology contents that can utilize above-mentioned announcement is made a little change or is modified to the equivalent embodiment of equivalent variations, in every case be the content that does not break away from technical solutions of the utility model, according to technical spirit of the present utility model to any simple modification that above embodiment did, equivalent variations and modification all still belong in the scope of technical solutions of the utility model.
