Abstract

The utility model relates to a compensation-type press-forming combined die for semi-circular thick steel plates, which comprises an upper die and a lower die. The combined die is characterized in that the upper die comprises a male die holder with inclined surfaces at the two inner side edges, and a semi-circular male die fixed on the male die holder; the lower die comprises a female die holder with retaining walls at the two edges, a female die press block, a rolling shaft and a press shaft; a semi-circular groove is arranged at the bottom of the female die press block and is connected with the rolling shaft that is embedded on the stair-shaped bench of the female die holder in a rotating manner; an inclined surface is arranged at the upper part of the female die press block; the pressing shaft is arranged on the inclined surface and is connected with the inclined surface in a rotating manner; and correcting blocks are fixed on the two sides of the bottom of the female die holder in the axial direction of the female die holder and have V-shaped cavities. The compensation-type press-forming combined die has the benefits that the circularity is controlled by changing the positions of the inclined surfaces and the correcting blocks, the female die press block is rotated under the work rebound action to release the rebound energy, so as to greatly reduce the ejection force and achieve the effect of forming the semi-circular thick steel plate of the large-sized hydraulic press with low ejection force, increase the utilization rate of the press, reduce the energy consumption and improve the forming quality.

Description

The compensation compacting assembling die of semicircle steel plate
Technical field
The utility model belongs to mould, relates in particular to the compensation compacting assembling die of a kind of semicircle steel plate.
Background technology
The large-tonnage bender is often adopted in the single and mini-batch production production of the moulding (as: the control tower pillar of offshore oil production well) of the above semicircle steel plate of 40mm, makes the steel plate local buckling, and accumulation is configured as a semicircle.This technological merit is availablely to finish than skinny device, but efficient is very low, and forming quality is also undesirable.For more large batch of steel plate semi-circular piece, then adopt the once-forming on large press.Because the bad control of the disposable springback capacity of colding pressing, and ejecting force is excessive after the moulding.Consider press ejecting force problem, have to adopt heat pressing process usually, on whole bending die, suppress after promptly steel plate being heated to 900-1000 ℃.This way forming quality is better, and screen resilience and ejecting force are also little, and efficient is also than bender height, but heat energy consumption is big, difficulty was also compared in operation when the workpiece of heating was suppressed, because the non-uniform temperature workpiece also can produce flexural deformation, did not reach technical standard.
The utility model content
The purpose of this utility model is to overcome the deficiency of above-mentioned technology, and provides a kind of employing energy-conservation cold moudling method, both can control springback capacity, makes the less compensation compacting assembling die of semicircle steel plate of ejecting force behind the component shaping again.
The utility model for achieving the above object, by the following technical solutions: the semicircle compensation compacting assembling die of a kind of steel plate, comprise, counterdie, it is characterized in that: described patrix comprises the punch frame on two inboard sideband inclined-planes and is fixed on semicircle punch on the punch frame, described counterdie comprises the die frame of two sideband barricades, the die briquetting, roller bearing and last item, described die briquetting bottom be provided with semi-circular recesses and be entrenched in roller bearing on the die frame and be and be rotationally connected, die briquetting top is provided with the inclined-plane, the inclined-plane is provided with it and is the last item that is rotationally connected, and described die frame barricade two bottom sides has correcting block to be die V font chamber along its axial restraint.
Or the inclined-plane of above-mentioned punch frame is provided with it and is the last item that is rotationally connected, and die briquetting top is provided with the inclined-plane.
The utility model beneficial effect: adopt the compensation compacting assembling die of the semicircle steel plate of cold-press moulding, can control springback capacity, make component shaping again after ejecting force less.Can adjust the radius of semicircle by the component locations of adjusting mould, make the less large press of ejecting force also can be used for colding pressing of steel plate semicircle, improved the utilization rate of press, have than bending or the higher efficient of hot-press method, lower energy consumption, better forming quality.
Description of drawings
Fig. 1 is the structural representation of embodiment 1;
Fig. 2 is the structural representation of embodiment 2.
The specific embodiment
Describe the specific embodiment of the present utility model in detail below in conjunction with accompanying drawing and preferred embodiment.
Embodiment 1
See accompanying drawing 1 for details, the semicircle compensation compacting assembling die of a kind of steel plate, comprise patrix 1, counterdie 2, described patrix comprises the punch frame 10 on two inboard sideband inclined-planes 3 and is fixed on semicircle punch 11 on the punch frame, described counterdie comprises the die frame 8 of two sideband barricades, die briquetting 9, roller bearing 7 and last item 4, described die briquetting bottom is provided with semi-circular recesses 9-1 and is and is rotationally connected with roller bearing 7 on the ladder platform that is entrenched on the die frame 8, die briquetting 9 tops are provided with inclined-plane 9-2, the inclined-plane is provided with and is the last item 4 that is rotationally connected with it, and described die frame two bottom sides has correcting block 6 cavity that is in the shape of the letter V along its axial restraint.
Embodiment 2
See accompanying drawing 2 for details, also can be made as last item to the inclined-plane on the punch frame, last item die briquetting top is made as inclined-plane 9-2.Play effect of the present utility model equally.
Operation principle: see accompanying drawing 1 for details, during the compacting beginning, die briquetting 9 is in the shaping end position, along with punch 11 bends slab workpiece 5, the last item 4 on the die briquetting 9 is pushed down on the inclined-plane 3 of punch frame simultaneously, this moment, 3 effect lower cavity die briquettings 9 moved to workpiece 5 directions on the inclined-plane, compressing workpiece 5 produces the compensated bend distortion, and the V font cavity of the correcting block 6 on the die frame also pushed workpiece 5 to by punch 11 simultaneously, and crooked slab 12 is out of shape again, after shaping finishes, punch frame 10 rises, and die briquetting 9 is along with the resilience of workpiece 5, backward rotation, when arriving the shaping end position at last, resilience just in time finishes.So only need just can eject workpiece 5,, realize requiring the semicircle of size by adjusting position and the position of correcting block 6 and the springback capacity that angle can be adjusted arc plate on inclined-plane 3 with less power.
The above only is preferred embodiment of the present utility model, is not structure of the present utility model is done any pro forma restriction.Every foundation technical spirit of the present utility model all still belongs in the scope of the technical solution of the utility model any simple modification, equivalent variations and modification that above embodiment did.
