Specific embodiment

As shown in Figures 1 to 5, the present embodiment is preferred embodiment, provides negative angle fast ram molding die simultaneously The part of two units is processed, the part of two units is arranged symmetrically.

Preferred embodiment according to the present utility model, the negative angle fast ram molding die, including lower die holder 1 and upper die holder 2, the lower die holder 1 is equipped with a lower template 11, and the upper die holder 2, which is equipped on one, takes off plate 21；In the lower template 11 along Feed direction is successively arranged the first reversed bending member 111, negative angle forming cavity 112 and negative angle and restores slot 113；The negative angle forming Cavity 112 restores slot 113 with the negative angle and is connected；And the inside edge of the negative angle forming cavity 112 is equipped with and described the The one reversed bending member 114 of reversed bending member 111 corresponding second；The first reversed bending member 111 and the second reversed bending Part 114 is the low correcting wedge in the high inside in outside, has an inclined-plane, the inclined-plane and horizontal direction (i.e. lower template 11 and upper Main parting line between de- plate 21) angle be key groove φ, and the angle of key groove φ is greater than 0 ° less than 90 °, and described first Reversed bending member 111 and the second reversed bending member 114 are the identical correcting wedge of key groove φ；The upper de- plate 21 be equipped with The de- material bending member 211 that the first reversed bending member 111 matches, is additionally provided with and matches with the negative angle forming cavity 112 Forming punching head 212, and equipped with restoring the recovery briquetting 213 that matches of slot 113 with the negative angle；The forming punching head 212 With a forming surface 2121, the forming surface 2121 and horizontal direction (main parting line i.e. between lower template 11 and upper de- plate 21) Angle be forming angle γ, and angle is not more than 90 °, and the first reversed bending member 111, de- material bending member 211, second are reversed curved Folding piece 114 and forming punching head 212 are easy wearing detail, are made, are conveniently replaceable, in specific embodiment of dismountable insert In, the recovery briquetting 213 is undertaken in itself by the upper de- plate 21, without separately setting.

The feed end of the lower die holder 1 is equipped with material correcting plate 12, for correcting material and limitation material width.

The discharge end of the lower die holder 1 is equipped with blanking sliding slot 13, and the corresponding linking negative angle restores slot 113.

A detecting switch 22 is additionally provided on the upper die holder 2, it is whether correct for perceiving feeding, as feeding correctly can be normal Operation, as feeding mistake can make board out of service.

Working principle: first reversed according to the reversed bending member 111 and second of the negative angle angle for the part processed adjustment first The angle of the key groove φ of bending member 114 adjusts de- material bending member 211, and adjustment molding according to the first reversed bending member 111 The angle of the forming angle γ of formed punch 212, the angle of the negative angle β of the part are 180 ° and subtract the key groove φ and the molding The sum of angle of the sum of the angle of angle γ, the key groove φ and the forming angle γ must be greater than 90 °；Then by material 3 by into Expect that the material correcting plate 12 at end enters in negative angle fast ram molding die, by material correcting plate 12 come correcting material and limitation material Width is expected, when material 3 is by the first reversed 111 upper surface of bending member, since the first reversed bending member 111 is the high inside in outside The correcting wedge at bottom, has an inclined-plane, and the punching press with the de- material bending member 211 that closes de- plate 21 make it is one on material 3 anti- To inflection point A in reversed bending when by the inclined-plane bottom edge of the first reversed bending member 111, make one end of material 3 formed one to Upper bending pre-folds curved segment 31, described to pre-fold curved segment 31 and horizontal segment 32 and be greater than 0 ° less than 90 ° in a reflex angle α, reflex angle α, The angle of the reflex angle α is identical as the angle of key groove φ of the described first reversed bending member 111；Then material 3 continues to send Material can keep material 3 by the second reversed bending member 114 when material 3 is when pre-folding curved segment 31 by negative angle forming cavity 112 Pre-fold curved segment 31 bending stablize, and due to the bending point B of material 3 pre-folded in curved segment 31 pass through the second reversed bending member It when 114 outside highest point, is bent under the action of 212 downward punching press of forming punching head, making to pre-fold curved segment 31, to form one downward Bending section 311 is bonded bending section 311 with the forming surface 2121 since forming punching head 212 has a forming surface 2121, rolls over Curved segment 311 is identical as the angle of forming angle γ of the angle of horizontal direction and the forming punching head 212, makes bending section 311 and pre- Negative angle β needed for forming one between bending section 31；Final material 3 continues feeding, and bending section 311 is located at negative angle and restores slot 113 Interior process, and the upward upper surface process for pre-folding curved segment 31 and being located at lower template 1 are rushed by the recovery briquetting 213 of upper de- plate 21 Pressure will pre-fold curved segment 31 and flatten, and make 0 ° of reflex angle α, finally completed the production of part, and skidded off by blanking sliding slot 13；It can root It needs according to the angle of negative angle β to the first reversed bending member 111, de- material bending member 211, the second reversed bending member 114 and molding punching First 212 are replaced, easy to operate, and save the cost.

The utility model is that a kind of structure is simple, easy to operate and save the cost negative angle fast ram molding die.

Although those familiar with the art answers the foregoing describe specific embodiment of the present utility model Working as understanding, we are merely exemplary described specific embodiment, rather than for the limit to the scope of the utility model Fixed, those skilled in the art modification and variation equivalent made by the spirit according to the utility model all should Cover in the scope of the claimed protection of the utility model.
