Abstract
The utility model relates to a liquid state bolt die hydrostatic machine with upper die and sliding block shaped core positioning device which comprises a hydrostatic machine main body composed of an upper beam, a sliding block, and a lower beam fixedly assembly through a locking nut and four vertical columns, wherein, the upper beam is provided with a locking die tank and an upper extruding tank, the piston rod of the locking die tank is fixedly connected with the sliding block, the piston rod of the upper extruding tank is connected with an extruding rod, the upper die is fixedly connected with the lower end face of the sliding block, the lower die is fixedly connected with the lower beam, a central positioning groove is arranged at the central position of the lower end face of the sliding block, a corresponding central positioning groove is arranged on the upper end face of the upper die, a positioning flange is fixedly arranged inside the central positioning groove on the lower end face of the sliding block, the lower half portion of the positioning flange is arranged inside the positioning groove of the upper die. The liquid state bolt die hydrostatic machine has the advantages of ensuring the concentration of the central hole of the sliding block and that of the lower die, which further makes the extruding rod running downwards smoothly pass through the central hole of the sliding block and that of the upper die to accomplish to the extrusion to the working pieces and prevent the damage or fracture to the extruding tank and the extruding rod.
Description
Technical field
The utility model belongs to the hydraulic machinery technical field, particularly relates to a kind of liquid-state die forging hydraulic press with patrix and slide block centre of form detent mechanism simple in structure, easy-to-install.
Background technology
The slide block of known liquid-state die forging hydraulic press and the connected mode of patrix are: have T-slot on the slide block lower surface, the upper surface of patrix is processed with circular hole, tommyhead bolt in patrix and the slide block T-slot is fastening, owing to exist the gap between T-slot on the slide block and the tommyhead bolt, after causing patrix to install, about taking place easily or the moving horizontally of fore-and-aft direction, the centre bore of patrix is difficult to and slide block centre bore centering.Liquid-state die forging hydraulic press locked mode cylinder is connected with slide block, the locked mode cylinder promotes slide block and moves downward, make patrix and counterdie matched moulds, squeeze cylinder is housed in the middle part of putting the beams in place, pressure ram is connected with squeeze cylinder, move up and down in slide block and patrix centre bore by pressure ram and to finish the extrusion modling of workpiece, because the slide block centre bore can not guarantee concentric with patrix centre bore junction, so cause the pressure ram of operation downwards can not be smooth and easy by the slide block centre bore and finish the extruding of workpiece, because bigger extruding force can cause pressure ram impaired, can cause the pressure ram fracture when serious like this.
Summary of the invention
The utility model provides a kind of slide block centre bore that guarantees concentric with the patrix centre bore for solving the technical problem that exists in the known technology, makes the smooth and easy liquid-state die forging hydraulic press with patrix and slide block centre of form detent mechanism by the slide block centre bore of squeeze cylinder pressure ram.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is:
Liquid-state die forging hydraulic press with patrix and slide block centre of form detent mechanism, comprise by upper beam, slide block and underbeam install by locknut and four columns and constitute the hydraulic press main body, on putting the beams in place, the locked mode cylinder is installed, the fixedly connected slide block of locked mode cylinder piston rod, between upper beam two locked mode cylinders, be fixed with squeeze cylinder, last squeeze cylinder piston rod connects pressure ram, patrix is by the fixedly connected slide block of tommyhead bolt lower surface, underbeam is by the fixedly connected underbeam of tommyhead bolt, it is characterized in that: have the centralized positioning groove near the center, lower surface at slide block, corresponding slide block locating slot place, patrix upper surface has locating slot, be fixed with locating flange in the slide block lower surface centralized positioning groove, interference fit is installed the Lower Half of locating flange in the patrix locating slot.
Advantage and the good effect that the utlity model has are: because the utility model is provided with locating flange in slide block lower surface and patrix upper surface opposite position, can guarantee that the slide block centre bore is concentric with the patrix centre bore, and then the pressure ram that makes downward operation is smooth and easy by slide block centre bore and patrix centre bore junction and finish the extruding of workpiece, prevents that the squeeze cylinder pressure ram from sustaining damage or rupture.The utility model also has simple in structure, easy-to-install advantage in addition.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1, put the beams in place; 2, locked mode cylinder; 3, go up squeeze cylinder; 4, slide block; 4-1, T-slot; 5, pressure ram; 6, tommyhead bolt; 7, patrix; 8, locating flange; 9, counterdie; 10, underbeam; 11, column; 12, locknut.
The specific embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
See also Fig. 1, liquid-state die forging hydraulic press with patrix and slide block centre of form detent mechanism, comprise by putting the beams in place 1, slide block 4 and underbeam 10 install the back by locknut 12 and four columns 11 and constitute the hydraulic press main body, on upper beam 1, two locked mode cylinders 2 are installed, the fixedly connected slide block 4 of locked mode cylinder piston rod, between 1 liang of locked mode cylinder of upper beam, be fixed with squeeze cylinder 3, last squeeze cylinder piston rod connects pressure ram 5, on the slide block lower surface, have T-slot 4-1, corresponding slide block T-slot position, patrix upper surface is processed with circular hole, the bolting that patrix 7 is bolted to connection in the T-slot of slide block lower surface connects the interior tommyhead bolt 6 of underbeam 10 upper surface T-slots, on the underbeam upper surface, have T-slot 10-1, counterdie 9 lower surfaces are provided with circular hole, counterdie 9 is by tommyhead bolt 6 fixedly connected counterdies 9, have the centralized positioning groove in center, slide block lower surface, corresponding slide block locating slot place, patrix upper surface has locating slot, be fixed with locating flange 8 in the centralized positioning of slide block lower surface is poor, interference fit is installed the Lower Half of locating flange 8 in the patrix locating slot.Like this by being installed in the locating flange of center, slide block lower surface and junction, patrix upper surface, can guarantee that the slide block centre bore is concentric with the patrix centre bore, and then the pressure ram that makes squeeze cylinder can smooth and easy junction by slide block centre bore and patrix centre bore when moving downwards, finishes the extrusion operation to workpiece.
The above, it only is preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, every foundation technical spirit of the present utility model all belongs in the scope of technical solutions of the utility model any simple modification, equivalent variations and modification that above embodiment did.
