Description

Pillar Stand Guiding Type Hydropress

Technical field

The utility model relates to a kind of hydraulic press technical field, especially refers to a kind of four Pillar Stand Guiding Type Hydropress.

Background technology

The large-scale oil pressure hydraulic press of the long stroke of present known four-column type large-tonnage, mainly form by entablature, sill, column, locknut, band cylinder slide block, for realizing requirement fast, then the cylinder bottom of the master cylinder in the band cylinder slide block close with entablature is equipped with prefill valve, this valve links to each other with surge-tank, also is connected with the control valve and the pump group of control prefill valve on prefill valve.In whole press was descending fast, master cylinder need be filled fluid by prefill valve.Therefore exist, master cylinder needs very high manufacturing cost and big flow prefill valve, also can't solve at topping up simultaneously, boosts, the relevant technologies problem in a series of actions conversion such as pressure release.

The patent No. has proposed new structure for the Chinese utility model patent that the 03258511.X name is called " the large-scale four post oil pressure of the long stroke of large-tonnage directly drive the fast hydraulic pressure machine " for this reason, its structure is to install entablature respectively by the two ends at four columns, sill, and install by locknut, installing band cylinder slide block on the column between entablature and the sill forms, it is characterized in that: quick oil cylinder is housed on entablature, the piston rod of oil cylinder even is loaded on band cylinder slide block fast, on a close left side, on the lower panel of the entablature of the right column the plate oil cylinder is housed respectively, on the piston rod of plate oil cylinder, plate is housed.

The shortcoming of this structure is, at first be, band cylinder slide block sliding up and down in column apart from oversize, and general fuselage is all huger concerning hydraulic press, obviously the diameter of column is bigger, and the required precision of column and band cylinder slide block mutual fit when moving up and down all is very high, because of guaranteeing the quality of the product of being pressed into like this, because band cylinder slide block is long at the sliding distance of column, not only increased the cost of raw material of column, more important is column and the processing distance of the mutual fit of band cylinder slide block will increase, thus increase expenses of labour with and increase and make man-hour, this does not have and has not improved cost of manufacture again in coagulating; Next is, because of the main purpose of this design is in order to accelerate the speed that moves up and down with the cylinder slide block, thereby reach the purpose that improves output, so the structure of its design is quite complicated, outside the needs master cylinder, also want quick oil cylinder, the plate oil cylinder, plate, when loading, master cylinder also needs to match with plate, this is external except that having increased cost of material, manufacturing process and man-hour have also been increased significantly, time-consuming taking a lot of work reduced the production efficiency of hydraulic press, and band cylinder ram travel that should design is long, naturally make the degree of wear between band cylinder slide block and the column suit place just high, and complicated structure parts also can occur and cooperates and be difficult to put in place, and the quality of stampings is descended, and nature will shorten the service life of hydraulic press; Be once more, the fuel tank of its hydraulic press, hydraulic oil pipe system are not to close to place together, so its floor space is big, the utilization rate in place are reduced.Therefore its structure awaits further to improve.

Summary of the invention

Technical problem to be solved in the utility model is that a kind of sound construction, precision height, footprints is little and cost of manufacture is low Pillar Stand Guiding Type Hydropress are provided at above-mentioned prior art present situation.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: this column guiding hydraulic press, include hydraulic oil pipe system, fuel tank, fixed head, moving platen, column, oil cylinder and electrical control division, the lower end and the bottom plate of described column fix, its upper end then fixes with upper mounted plate, described moving platen is for can slide up and down to overlap in the column of string between last bottom plate, described oil cylinder, hydraulic oil pipe system and fuel tank are connected successively, and hydraulic oil pipe system links to each other with electrical control division, it is characterized in that being provided with middle fixed head in the column between described moving platen itself and the upper mounted plate, described oil cylinder is for placing between fixed head and the upper mounted plate, links to each other and place the piston one end of oil cylinder to stretch out from the lower end of oil cylinder with the moving platen that is positioned at the below.

As improvement, described hydraulic oil pipe system and fuel tank can be stacked up and down and place the column top, make hydraulic oil pipe system and fuel tank and column synthesize vertical integrative-structure.

The above-mentioned fixed structure of going up between bottom plate and the column can be for being gone up by big nut on the platform level face that bottom plate is locked in column.For bottom plate is more stably placed on the ground, described bottom plate can be fixed in the base.

As further improvement, its periphery of described column also can be equipped with the upper, middle and lower sleeve pipe, described upper mounted plate is gone here and there in column for cover, and be held on the upper surface of sleeve pipe and be fixed on the column by big nut, described in fixed head go here and there in column for cover, and insert and put between sleeve pipe and the middle sleeve, and moving platen is stretched out in the lower end of middle sleeve, described bottom plate is also gone here and there in column for cover, and its upper surface contacts mutually with the setting of casing lower end, and is fixed on the column by big nut.

For make piston install and change more convenient, described in fixed head be provided with oil cylinder cover, described piston promptly stretches out from oil cylinder cover with moving platen and links to each other.

Compared with prior art, advantage of the present utility model is, at first be, because of between last bottom plate, having increased fixed head in, thereby make moving platen break half sliding up and down of column apart from contracting, so reduced the position that rubs mutually, the mutual suit place of column and moving platen effectively, also reduced highly difficult working position and cut down finished cost, simultaneously, because fixed head between column, having increased together, from and further strengthened the integrally-built fastness of column, make the positioning accuracy between four root posts (being lead) more stable, complete machine intensity is also strengthened; Next is, and is of the present utility model simple in structure, only master cylinder is folded between upper mounted plate and the middle fixed head, and piston links to each other with moving platen, and structure is very simple, the stable height that parts cooperate, thus prolong service life of hydraulic press effectively; Be once more, hydraulic oil pipe system of the present utility model adopts the integrated package design, and hydraulic oil pipe system overlayed on the fuel tank, fuel tank is installed in the body upper of being made up of four root posts again, complete machine forms vertical integrative-structure, saved floor space effectively, the operating space is increased accordingly, more mold exchange, the also more spacious convenience of the goods of taking; Also have the utility model also to be equipped with the upper, middle and lower sleeve pipe in the periphery of column, thereby can reduce the material requirements of column, and, just can guarantee the machining accuracy of complete machine structure as long as in middle sleeve, adopt high-precision processing, so just reduced raw bodies and processing cost further.
