Description

A kind of numerical control bending cutter for suppressing deep U-shaped product

Technical field:

The utility model relates to mechanical and stamping die technology, specifically a kind of number for suppressing deep U-shaped product Control bending cutter；It can be used for processing the product of deep U-shaped character shape.

Background technique:

The product of the bending cutter produced at present is mainly used to shape 90 ° or obtuse angle degree, the production for deep U-shaped structure Product, though uncomplicated, its structure and bending cutter generate interference, and the limitation for causing equipment to use cannot play its maximum Use value；And product variety is various, and the specification of product and the size of bending are different, thus brings to processing Certain difficulty.

Utility model content:

The purpose of the utility model is to overcome the deficiencies of above-mentioned prior art, and provide a kind of number for suppressing deep U-shaped product Control bending cutter；Mainly solve the problems, such as that bending cutter cannot process the special shape products such as deep U-shaped in the prior art.

The technical solution of the utility model is: a kind of numerical control bending cutter for suppressing deep U-shaped product, including blade, special Different place is that the blade top sets link slot, has threaded hole in link slot；The blade is integrally in arcuation, under blade End is the point of a knife being integrated with blade, and the tip of point of a knife is in arc-shaped, the center of arc of point of a knife always with the center line of threaded hole On one wire.

Further, the blade side, which is cut, is cut into deep throat inlet machine shape, and blade side is integrally in arcuation；The blade Left side extends to the right, directly connect being aligned with tool arc, and the right side of blade is in inverted "L" shape, and bottom end is directly and point of a knife Circular sliding slopes being aligned.

Further, the point of a knife is in 85 °, and has the circular arc of a radius 5mm to carry out transition at tip.

Further, the threaded hole in the link slot is 2.

Compared with the prior art a kind of numerical control bending cutter for suppressing deep U-shaped product described in the utility model has as follows Good effect: 1, can be used for processing the product of deep U-shaped character shape, will not interfere；2, the shape of tool is calculated by accurate, It ensure that cutting-tool's used life is long；3, the tip of point of a knife is in always on the center line of active force, ensure that the structure of cutter Intensity will not occur bending and deformation；4, there is circular arc to carry out transition at tip, increase the forced area contacted with product, reduce equipment Pressure；5, its mounting means is identical as existing cutter, need not be transformed again to existing bending machine, make full use of existing equipment Function plays its maximum use value.

Detailed description of the invention:

Fig. 1 is the side structure schematic diagram of the utility model；

Fig. 2 is the positive structure schematic of the utility model；

The machining state schematic diagram of Fig. 3 the utility model；

Fig. 4 is the structural schematic diagram of deep U-shaped product described in the utility model.

Specific embodiment:

With reference to the accompanying drawing and specific embodiment is described in further details the utility model.

Embodiment 1, referring to Fig. 1,2, a numerical control bending cutter generally cuboid processes blade 2 according to design requirement, will 2 side of blade, which is largely cut, is cut into one compared with deep throat inlet machine shape, and 2 side of blade is integrally in arcuation；2 top of blade is machined with wide 45mm, depth The link slot 1 of 16mm has M12 at 2, the threaded hole of deep 25mm, the fixation for cutter in link slot 1；2 lower end of blade has and knife The tip of the point of a knife 3 that body 2 is integrated, point of a knife 3 is in arc-shaped, and the center of arc of point of a knife 3 is always with the center line of threaded hole one On bar line, i.e., the center of arc of point of a knife 3 is in always on the center line of pressing force；The left side of blade 2 extends to the right, Directly with 3 circular sliding slopes being aligned of point of a knife, the right side of blade 2 is in inverted "L" shape, bottom end directly with 3 circular sliding slopes being aligned of point of a knife； Point of a knife 3 is in 85 °, and has the circular arc of a radius 5mm to carry out transition at tip, increases the forced area contacted with product 4；It is formed A kind of numerical control bending cutter of the compacting depth U-shaped product of the utility model.

A kind of numerical control bending cutter for suppressing deep U-shaped product described in the utility model, as shown in Figure 3,4, when work, knife What the blade of tool used aditus laryngis shape keeps away bit architecture, and when suppressing the product 4 of deep U-shaped, what product 4 was exactly in cutter keeps away an aditus laryngis It is interior, it will not interfere, cutter is lifted after processing, diagonally lower right can be taken off product 4, and if using common straight Cutter can then generate interference, can not process product 4.

The above is only a part of the embodiment of the utility model, instead of all the embodiments.It should be pointed out that above-mentioned Embodiment is not construed as limitations of the present invention, and the protection scope of the utility model should be with model defined by claim Subject to enclosing.Every other embodiment obtained by those of ordinary skill in the art without making creative efforts, all Belong to the protection scope of the utility model.
