Abstract
The utility model relates to a swinging block die comprising an upper die, a lower die, an upper die sliding block and an ejector plate, and the ejector plate is connected with the upper die through the upper die sliding block. The swinging block die is characterized by further comprising two swinging blocks which are L-shaped, and the included angle of the internal sides of the swinging blocks is smaller than 90 degrees; and each swinging block is movably mounted on the lower die through a rotating shaft; the apex angle of the ejector plate acting on the swinging blocks is the same as the included angle of the internal sides of the swinging blocks; and the swinging blocks are made of alloy materials by once casting. The swinging block die has the performance of rotating to a certain angle by utilizing the swinging blocks, can bend and machine a plate piece to have an angle smaller than 90 degrees so as to be capable of counteracting the resilience amount of the plate piece, thereby ensuring the 90-degree bent edge of the formed plate piece.
Description
Technical field
The utility model relates to a kind of machining mould, specifically relates to a kind ofly can guarantee the rectangular centering block mould of metal sheet flanging, belongs to the Machining Technology field.
Background technology
At present a lot of shell parts for gain in strength, electromagnetic radiation shielding and environmental protection, all need to use metal sheet.Metal sheet is to carry out bending with mould, but owing to the property relationship of metal sheet, flanging has resilience to a certain degree, its springback capacity difference of the metal sheet of unlike material after moulding, just the making of part very accurately causes very big difficulty to required angle for this, has increased difficulty of processing.Especially to the part of the 90 degree right angle flangings of will hoping for success, the mould that adopts all is by patrix and fixing counterdie acting in conjunction at present, metal sheet is bent into the right angle, the moulding angle of counterdie is 90 degree, therefore, because influence springback is difficult to guarantee the accurate of angle, the angle of general two flangings all can be greater than 90 degree after the moulding.
The utility model content
For solving the deficiencies in the prior art, the purpose of this utility model is to provide a kind of can guarantee the rectangular centering block mould of metal sheet flanging, takes all factors into consideration the influence of springback capacity, realizes by set up centering block in mould.
For achieving the above object, the utility model is to realize by following technical scheme:
A kind of centering block mould comprises upper die and lower die, goes up mode slider and die pad, and die pad is connected with patrix by last mode slider, it is characterized in that also comprising two centering blocks, described centering block becomes " L " shape, and its inboard angle is less than 90 degree, and each centering block is movably arranged on the counterdie by turning cylinder; Angle with the drift angle of centering block effect on the described die pad is identical with the inboard angle of centering block.
Aforesaid a kind of centering block mould, it is characterized in that: described centering block is formed by the alloy material one-step casting.
Description of drawings
Fig. 1 is the structural representation of centering block mould of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is done concrete introduction.
Fig. 1 is the structural representation of centering block mould of the present utility model.As shown in the figure, centering block mould of the present utility model comprises counterdie 1, centering block 2, patrix 3, die pad 4 and last mode slider 5.Die pad 4 is installed on the patrix 3 by last mode slider 5.2 one-tenth " L " shapes of two centering blocks, described centering block 2 is formed by turning cylinder by the alloy material one-step casting and is movably arranged on the counterdie 1, and the moving axis certain angle can rotate.The angle of centering block 2 inboards is less than a angle of 90 degree, is the 90-a degree; Equally, the angle of the drift angle of die pad 4 front ends and centering block 2 effects also is less than 90 degree, and is identical with centering block 2 inboard angles.
Adding man-hour, the slip of die pad 4 by last mode slider 5 with metal sheet to sinciput, by with the effect of centering block 2, with the metal sheet bending.In the process of die pad 4 reaches, centering block 2 is done corresponding the rotation, can not rotate until die pad 4 again.At this moment, the side of centering block 2 and the vertical direction shape of patrix be a in an angle, and by the acting in conjunction of die pad 4 and centering block 2, the bending angle of metal sheet is less than 90 degree, is the 90-a degree.Metal sheet has certain springback capacity after breaking away from mould, just in time can offset a angle, makes the both sides of bending just in time form 90 degree.In order to guarantee that the bending angle of metal sheet just in time is 90 degree after the resilience, a angle can specifically be determined according to the metal sheet of unlike material, makes resilience just in time offset the angle that surpasses, guarantee to process accurately.
Show and described basic principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
Claims (2)
