Abstract
The utility model discloses a die for closing-in machining of a slotted self-locking nut. The die for closing-in machining of the slotted self-locking nut is mainly applied to a stamping device, and is used for carrying out closing-in on the slotted self-locking nut without a specific self-locking area by using a stamping method. According to the technical scheme, a product to be machined is placed into a cavity of a closing-in female die (3) of the die for closing-in machining of the slotted self-locking nut, an upper die (4) is fixed on a sliding block of the stamping device, and the ejecting-in height of an adjusting ejecting rod (5) and the stamping height of the upper die (4) are adjusted according to deformation of the product. Permanent deformation can be formed at the slotted position of the product according to the shape of the closing-in female die (3) through stamping of the upper die (4) to the product, so that the self-locking function of the slotted self-locking nut can be achieved, and the design requirements of the product are met. The die for closing-in machining of the slotted self-locking nut mainly comprises a lower die plate (1), a fixing plate (2), the female die (3), the upper die (4), the ejecting rod (5) and the like. The die for closing-in machining of the slotted self-locking nut is characterized in that the closing-in female die (3) is placed into the fixing plate (2), the long end of the ejecting rod (5) is placed into the lower die plate (1), the short end of the ejecting rod is placed into the closing-in female die (3), an assembly after assembly is fixed with the lower die plate (1) through bolts (6), then, the assembly is assembled on the stamping device for closing-in, and the upper die (4) is fixed on the sliding block of the stamping device.
Description
Technical field
The present invention relates to a kind of self-locking nut crimping mould, mainly is for pressing equipment, the mould that the method for employing punching press closes up to the fluting self-locking nut that does not have specific self-locking zone.
Background technology
The domestic fluting self-locking nut of processing all has specific self-locking zone (this zone is cylindrical or truncated cone-shaped) at present, generally all be to utilize scroll chuck or hydraulic test, adopt method that point closes up can satisfy the requirement of product to its closing in, but can't adopt the method for a closing in for the fluting self-locking nut (for example: slot on six aspects) that this class does not have a specific self-locking zone.
Summary of the invention
The present invention is directed to the problems referred to above, propose to adopt the processing method of punching press, and developed the closing-in mould of a cover at such nut special use.
The scheme that technical solution problem of the present invention adopts is: the die cavity of processed product being put into the closing in die (3) of fluting self-locking nut crimping processing mold, patrix (4) is fixedly on the slide block of pressing equipment, the press height that heads into height and patrix (4) of regulating push rod (5) according to the deflection of product.Make product along closing in die (3) shape permanent distortion take place at the fluting place by patrix (4) to the punching press of product, thereby reach the function of nut self-locking, satisfy the product design requirement.
And fluting self-locking nut crimping processing mold mainly is made up of lower bolster (1), fixed head (2), die (3), patrix (4), push rod parts such as (5), it is characterized in that: closing in die (3) is placed in the fixed head (2), the long end of push rod (5) is put into lower bolster (1), short end is put into closing in die (3), be assembled on the pressing equipment of closing in usefulness after the assembly that assembles and lower bolster (1) being fixed by bolt (6), patrix (4) is fixed on the slide block of pressing equipment again.
The interior cavity shape of die (3) that wherein closes up is according to the configuration design of product, and by non-deformation zone (3.1), deformed area (3.2) and push rod workspace (3.3) are formed.Non-deformation zone (3.1) is the product force area, and its height h1 is that product force area height L1 deducts flange thickness.Deformed area (3.2) is shaped as bullet for product locking zone, and its height h2 is that the height L of product deducts product force area height L1, and angle of taper X is between 3 ~ 12 degree.Aperture, push rod workspace (3.3) is greater than the maximum excircle dimension of push rod (5), i.e. push rod (5) brace table diameter.The interior cavity shape of closing in die (3) can be six squares, also can be bihexagon, common chamfering profile, sphere profile or irregular how much profiles.
The length of push rod (5) is generally 40mm, and it is shaped as the cylinder of a band brace table, and its brace table is positioned at 1/5th to 1/8th places of push rod (5) upper end, and its diameter is less than the diameter of push rod workspace (3.3) in the die (3), and its thickness is 3mm; The computational methods of push rod brachycephaly diameter D:
D=product diagonal diameter or outside diameter-2 * (L-L1) * (tgX/2)-0.5;
X is closing in die (3) angle of taper;
Beneficial effect of the present invention: utilize closing-in mould of the present invention, adopt stamping forming mode to process this type of fluting self-locking nut, designing requirement and the product that can satisfy product preferably have higher uniformity.By changing the closing in requirement that die (3) can satisfy this series products different size.This closing in method and mould can satisfy the large batch of production and processing of product.

The specific embodiment
Embodiment 1:
Be example to process six sides shown in Figure 11 fluting self-locking nut, the present invention is described in detail.
According to profile and the size of converted products, for being designed to hexagonal pyramid shape, the height h1 of non-deformation zone (3.1) is 2.54mm with the interior cavity shape of closing in die (3).The height h-h1 of deformed area (3.2) is 3.58mm, and angle of taper X is 10 degree.Aperture, push rod workspace (3.3) is 12.5mm.
The length of push rod (5) is 40mm, and its brace table is apart from the 5mm place on push rod (5) top, and the brace table diameter is 12mm, and its thickness is 3mm; Push rod brachycephaly diameter D is 6mm.
Then closing in die (3) is placed in the fixed head (2), the long end of push rod (5) is put into lower bolster (1), short end is put into closing in die (3), be assembled on the pressing equipment of closing in usefulness after again the assembly that assembles and lower bolster (1) being fixed by bolt (6), patrix (4) is fixed on the slide block of pressing equipment, will product processed be placed in the closing in die (3), regulate the press height that heads into height and patrix (4) of push rod (5) according to the deflection of product.Make product with die (3) shape permanent distortion take place along closing up at the fluting place by patrix (4) to the punching press of product, thereby reach the function of nut self-locking, this closing in method and mould are fit to each specification product of such self-locking nut, and satisfy the product design requirement.
