Abstract
The present invention relates to an overhead oil cylinder type four-post press. A frame of the press can be formed by the method that a base is fixed with vertical posts on the circumference. A crankshaft is fixed on an upper separator, and the crankshaft is connected with a slide block through a connecting rod; a working bedplate is arranged on the base, and a lower die is put on the working bedplate corresponding to an upper die arranged on the slide block. The upper ends of the vertical posts are connected with a piston rod of an oil cylinder. The upper part of the upper separator is fixed on an oil cylinder body, the middle part is sheathed on the vertical posts, and the lower part is spaced by regulating nuts sheathed on the vertical posts. The present invention has the advantages that the upper separator is connected with the oil cylinder, the pressure of the slide block can be regulated by the oil cylinder, so the damage of the dies and the press can be avoided; accordingly, the service life of the press and the dies can be extended; meanwhile, the upper separator can be lifted up in a comparatively large range, so height the upper die can be heightened; thus, the observation and the maintenance of the dies can be convenient; by changing the spacing nuts on the vertical posts, the closing height of the slide block and the working bedplate can be regulated.
Description
Technical field
The present invention relates to a kind of forcing press, particularly a kind of preset hydro-cylinder type four column press.
Background technology
Existing forcing press as shown in Figure 1, its base 13 is fixed the frameworks that constitute forcing presses with the column 10 around it, working plate 12 is set on the base 13, place counterdie 11 on the working plate 12, corresponding with the patrix 9 on being arranged on slide block 7, fixing entablature 3 on the column, entablature 3 is fixed the bent axle 4 on it, bent axle 4 is connected with slide block 7 by connecting rod 5 and drives slide block, column 10 limits are provided with guide rail 8, slide block 7 moves up and down along guide rail 8, also has the adjusting nut 16 of adjusting slider and entablature distance on the connecting rod.Because the entablature 3 of forcing press is whole with base 13 or fixedlys connected; therefore the adjustment of slide block 7 positions is to realize by the position of regulating the nut 16 on the connecting rod 5; regulate with this method; labour intensity is big; operation inconvenience, precision is not high yet, and does not have overload protection function; if the improper meeting in slide position directly is stamped on the bed die, influence the service life of mould and equipment.
Summary of the invention
Technical problem to be solved by this invention is to overcome the above-mentioned defective of prior art and a kind of preset hydro-cylinder type four column press is provided, and makes its position that can conveniently adjust mould, prevents the generation of forcing press overload.
The present invention solves the problems of the technologies described above the technical scheme that is adopted:
Preset hydro-cylinder type four column press, its base and the fixing framework that constitutes forcing press of column all around, fixed crankshaft on the entablature, bent axle is connected with slide block by connecting rod, and working plate is set on the base, place counterdie on the working plate, corresponding with the patrix on being arranged on slide block, be characterised in that: described column upper end is connected with the piston rod of oil cylinder, and entablature top is fixed on the cylinder body, the middle part is enclosed within on the column, and the bottom is spacing by the adjusting nut that is enclosed within on the column.
Compared with prior art, the invention has the advantages that: adopt entablature to be connected, adjust the pressure of slide block, so can prevent the generation of limited slip block overload, avoid mold damage and equipment, thereby prolong the service life of equipment and mold by oil cylinder with oil cylinder.Simultaneously, by oil cylinder, lifting entablature in a big way, thus promote the patrix height, facilitate like this and observe and the maintenance mould; By changing the stop nut on the column, just can realize the adjustment of slide block and press bench plate closing height in addition.
Description of drawings
The structural representation of the existing forcing press of Fig. 1;
Fig. 2 is a structural representation of the present invention.
The specific embodiment
Embodiment describes in further detail the present invention below in conjunction with accompanying drawing.
As shown in Figure 2, preset hydro-cylinder type four column press, around its base 13 four columns 10 are set, column 10 upper ends are connected with the piston rod 2 of oil cylinder, and entablature 3 is connected with cylinder body 1, the middle part of entablature 3 is enclosed within on the column 10, the bottom is spacing by the adjustment nut 6 that is connected column 10, column 10 side fixed guides 8, and slide block 7 moves up and down along guide rail 8, slide block 7 is linked to each other with bent axle 4 by connecting rod 5, and bent axle 4 is fixed on the entablature 3.Fixing mold 9 below the slide block, relative with bed die 11 on being fixed on workbench 12, workbench 12 is fixed on the base 13.
13 of above-mentioned column 10 and piston rod 2 and bases are easy for installation and removal like this with being threaded.
Above-mentioned forcing press is under oil cylinder 2 effects, and entablature 3 drives slide block 7 along column 10 and moves up and down in overall along the guide rail 8 on the column.Adjusting nut 6 can adjusting slider 7 and the spacing of working plate 12, and plays entablature 3 descending positioning actions.
During operate as normal, regulate and adjust nut 6, when making the bent axle 4 that is fixed on the entablature 3 be in lower dead point position, patrix 9 counterdies 11 are just closed, regulate oil cylinder 2 cavity of resorption oil circuit pressure greater than stamping press with place on the slide block 7 and put all and the weight of bed die associated components on the entablature 3, at this moment, the logical fuel tank in oil cylinder epicoele road.
If stamping press is excessive during work, the pressure oil of oil cylinder cavity of resorption is at hydraulic system effect underflow oil sump tank, and is up thereby entablature 3 breaks away from adjustment nut 6, patrix can not run into counterdie, even break counterdie, thereby realize hydraulic pressure overload protective.
During machine works, the stamping press size is controlled by the oil pressure of overhead oil cylinder cavity of resorption, in the height adjustment range that machine is demarcated, adjusts the nut upper-lower position by regulating, and satisfies the required shut height of mould, and bigger die change space is arranged.
Need repairing or when adjusting mould, hydraulic system is at four oil cylinders, 2 epicoele injection pressure oil, 1 of cylinder body moves up, driving the entablature 3 that connects on it moves up, driving slide block 6 by bent axle 4 and connecting rod 5 rises overally along guide rail 8, make up and down mould away from, make things convenient for inspection, repairing and the adjustment of mould.
Claims (2)
1. preset hydro-cylinder type four column press, its base and the fixing framework that constitutes forcing press of column all around, fixed crankshaft on the entablature, bent axle is connected with slide block by connecting rod, and working plate is set on the base, place counterdie on the working plate, corresponding with the patrix on being arranged on slide block, be characterised in that: described column upper end is connected with the piston rod of oil cylinder, and entablature top is fixed on the cylinder body, the middle part is enclosed within on the column, and the bottom is spacing by the adjusting nut that is enclosed within on the column.
