Abstract
The utility model discloses a dentless bending mould for bending plates, comprising an upper mould and a lower mould, wherein, the surface of the lower mould is provided with a notch of which the surface is provided with a rolling needle; the outer circumference surface of the rolling needle is additionally provided with a plurality of auxiliary rolling needles. The utility model avoids dents on the surfaces of the bent plates so as to eliminate corrosion phenomena in the dents of the prior art.
Description
Technical field
The utility model belongs to a kind of sheet material apparatus for bending.
Background technology
At present, existing apparatus for bending only is made of the counterdie of patrix, band recess, in sheet material bending process, sheet material is subjected to the pressure of counterdie load line very big, simultaneously, when sheet material stretches in the bending distortion, also be subjected to the friction of counterdie, this phenomenon is hour more obvious in the edge of counterdie or bending angle, cause being badly damaged of sheet material coating, form tangible impression, had a strong impact on the outward appearance of sheet material, the impression place also becomes the originating point of sheet material rust corrosion simultaneously
Summary of the invention
The purpose of this invention is to provide a kind of stressed rationally, sheet material bending rear surface do not have the no impression bender of impression.
For achieving the above object, technical scheme provided by the utility model is a kind of no impression bender, and it comprises upper die and lower die, and the counterdie surface has recess, and recessed surfaces is provided with needle roller.
The outer circumference surface of needle roller also is equipped with a plurality of secondary needle rollers.
Compared with prior art because the utility model changes the edge of counterdie into the fineness higher face of cylinder, increased the extended distance of counterdie relatively, reduce sheet material bending process middle and lower part and be subjected to pressure on the line of force, and in the counterdie recessed surfaces, establish needle roller, it during pressing mold sliding friction, because of a little sheet materials through bending do not have impression, thereby eliminated the corrosion phenomenon at the impression place of prior art sheet material.
Description of drawings
Shown in the drawings is structural representation of the present utility model.
The specific embodiment
No impression bender shown in the drawings is to be made of patrix 1, counterdie 3, and counterdie 3 surfaces have recess, and recessed surfaces is provided with needle roller 5.Sheet material 2 is put into mould, in sheet material bending process, change the needle roller 5 of rolling into sheet material friction part, the friction that makes sheet material 2 and counterdie is based on sliding friction, change into based on rolling friction, greatly reduce in the sheet material bending process destruction that counterdie and sheet material sliding friction cause plate surface.More flexible for the rolling that makes needle roller, effectively, the outer circumference surface of needle roller 5 also is equipped with a plurality of secondary needle rollers 4.
Claims (2)
1, a kind of no impression bender, it comprises patrix (1), counterdie (3), the counterdie surface has recess, it is characterized in that described recessed surfaces is provided with needle roller (5).
2, no impression bender according to claim 1 is characterized in that the outer circumference surface of described needle roller (5) also is equipped with a plurality of secondary needle rollers (4).
