Abstract
The utility model provides a high-precision flat plate type pressing machine, which comprises a dismountable pressing machine framework, a guide positioning device and a pressure system, wherein the guide positioning device is used in the ascending and descending process of a press plate. The stress type of an engagement part of an upright post and a cross beam is changed, i.e. a screw bolt of the combining part is changed from a state suffering from cutting stress into a state suffering from pulling stress, so the force bearing capability of the screw bolt is greatly enhanced, so the safety of the pressing machine is enhanced. A foot rest and a foot rest plate of a welding element are completely omitted in the guide positioning device used in the ascending and descending process of the press plate disclosed by the utility model, so the press plate and the framework can not deform through being heated in the welding process, and the processing precision of the pressing machine is ensured. The pressure system of the pressing machine disclosed by the utility model enlarges the pressed support range of products processed by the pressing machine, and the elastic deformation of the processed products is reduced, so the thickness deflection of the products processed by the pressing machine is controlled within the minimum degree.
Description
Technical field
The utility model relates to a kind of flat press, particularly a kind of flat press with high precision performance.
Background technology
Traditional single or multiple lift platen-press, its version generally are divided into board-like press of pressure type and the board-like press of press-down type.Press is at open configuration, and grade size of opening of adjacent two block pressur plates is commonly referred to interlamellar spacing.Open a grade number in press, be commonly referred to the number of plies of this press.The press that (contains 2 layers) more than 2 layers is called multidaylight press.
As shown in Figure 1, the board-like press of last pressure type by press frame 1, workbench 2, polylith pressing plate 3, organize hydraulic cylinder 4, hydraulic system 5 and electric control system 6 more and form.Many group hydraulic cylinders 4 are installed in the top of sill 122, cylinder plunger 41 up, the center line of the centrally aligned press entablature 121 of plunger face, workbench 2 is fixed on the cylinder plunger 41, between workbench 2 and the entablature 121, place polylith pressing plate 3 according to the number of plies needs of design.When press opened, the neutral gear that forms between adjacent two block pressur plates 3 called off shelves.Opening shelves is to be used for placing the goods that the client will process.During press work, cylinder plunger 41 upwards raises, and push work platform 2 rises, and pressing plate 3 is also closed from the bottom up thereupon, and the goods that are placed between the pressing plate are pressed.After finishing the pressurization task, release, cylinder plunger 41 is shunk back to initial position downwards.The open-shaped attitude of press.
As shown in Figure 2, the board-like press of press-down type also by press frame 1, workbench 2, polylith pressing plate 3, organize hydraulic cylinder 4, hydraulic system 5 and electric control system 6 more and form.Be that with the difference of last pressure type press hydraulic cylinder 4 is installed in the bottom of entablature 121, cylinder plunger 41 down, backhaul hydraulic cylinder 7 is installed in the top of entablature group 121, backhaul cylinder plunger 71 up.The center line of the centrally aligned press sill 122 of cylinder plunger face.Workbench 2 is fixed on the cylinder plunger 41.Between workbench 2 and the sill 122, place polylith pressing plate 3, when press opens, shelves are arranged out between the pressing plate according to the number of plies needs of design.During work, cylinder plunger 41 stretches out downwards, and backhaul cylinder plunger 81 is shunk back downwards.Workbench descends, and pressing plate 3 also descends thereupon.Press closes, pressurization.Behind the end-of-job,
As shown in Figure 3, this press frame is to be processed into sheet frame by the monoblock steel plate, becomes non-dismountable framework with connecting piece 21, oil cylinder beam 20, base 22 Combination Welding then.Column 11 and entablature 121, sill 122 are formed one press sheet frame.Because its size is very big, super wide superelevation when causing transportation, thus increased the cost of transportation height.In addition, use factory also to be difficult to this large-sized framework is transported the workshop, need to remove door and window sometimes, sometimes even the roof will be removed, with crane framework is transported the workshop and install.Therefore, in order to reduce cost of transportation and installation cost, use factory that detachable framework is had strong requirement.
As shown in Figs. 4a and 4b, can utilize bolt 13 that column 11 and upper and lower crossbeam 121,122 are connected into framework.But when press was worked, bolt 13 can be subjected to very big shear stress and make that bolt 13 is easy to be cut off.
Shown in Fig. 4 c, for strengthening the shear stress of bolt, Chinese patent discloses for ZL96247591.2 number at the inboard of the column 11 at entablature 121 and sill 122 two ends installing location-plate 14, increases the intensity of bolt 13 with location-plate 14.But this location-plate 14 need be installed in the mode of welding, thereby the heat of welding can make column produce the degree of deviation that distortion directly has influence on the pressing precision and the thickness of the product of being suppressed.
Shown in Fig. 8 a and Fig. 8 b, the pressing plate 3 of traditional press is welded with 4 leg rests 31.After pressing plate leaves shelves and opens fully, the position that toe board that pressing plate relies on leg rest 31 to be parked in to be welded on the press frame 1 32 is default.Yet this toe board 32 and leg rest 31 need be welded in respectively on press frame 1 and the pressing plate 3 in the mode of welding, and the heat of welding can make press frame 1 and pressing plate 3 produce distortion, thereby directly has influence on the machining accuracy of press.
Please be simultaneously in conjunction with Figure 14 and Figure 15, the existing hydraulic cylinder center line 42 of going up the board-like press of pressure type is aimed at entablature center line 123 respectively, when press is worked, produce the same position act on simultaneously on the press converted products 9 on entablature fulcrum 124 and the hydraulic cylinder impetus 43 respectively and rightabout power, make this position that bigger strain take place, and less strain has taken place, thereby make press converted products 9 have bigger thickness deviation in other positions away from the press converted products 9 of cylinder plunger 41.
