Description of drawings
Describe the present invention in detail below in conjunction with the drawings and specific embodiments;
Fig. 1 is one embodiment of the invention;
Fig. 2 is the A section enlarged drawing of Fig. 1;
Fig. 3 is that activity of the present invention enters the minor structure schematic diagram.
The specific embodiment
For technological means, creation characteristic that the present invention is realized, reach purpose and effect is easy to understand, below in conjunction with the specific embodiment, further set forth the present invention.
Embodiment:
Referring to Fig. 1 and Fig. 2, the bending molding structure for stamping mould of the present embodiment, it comprise patrix 10 and with the suitable counterdie 20 of patrix 10, be provided with to fluctuate die 22 and the die fixed head 23 that is arranged on die 22 belows on counterdie 20, the die fixed head is processed with mounting groove 230 on 23 lower surfaces, by mounting groove 230, swingable activity is installed and enters son 21 on counterdie 20, be fixed with on patrix 10 to enter with activity the angle that son 21 suitable Bending punches 11 and control activity enter sub 21 pendulum angles and rush part 12.
In the present embodiment, referring to Fig. 3, it is L-shaped that activity enters son 21 lower end, and be movably arranged in mounting groove 230; Activity enters son 21 upper end passes die 22 and inserts in die cavity on die 22, processes L-shaped bending skewed slot 210 on a side in the top, processes circular arc chamfering at bending skewed slot 210 bending parts, easy to use.The bending skewed slot 210 of the present embodiment can arrange according to the negative angle size that will process the bending product bending skewed slot 210 of different large low-angles and the degree of depth.
Another side that activity enters sub 21 upper ends namely with a side of the side thereof opposite that processes bending skewed slot 210 on processing enter with movable the first sliding bevel 211 that sub-length direction tilts, and addition goes out L-shaped step groove 212 below this side, guaranteed that activity enters between son 1 and die 22 to have the free gap, is convenient to swing and bending angle adjustment that activity enters son 21.
On patrix 10, Bending punch 11 and angle are installed rush part 12; This Bending punch 11 upper ends are fixed on patrix 10, one side of its lower end is provided with the negative angle skewed slot 110 for bending, this negative angle skewed slot 110 is that relative Bending punch length direction tilts and inverted L shaped groove, matches with the bending angle size of negative angle skewed slot 110 in the angle of inclination of this bending skewed slot 210; And negative angle skewed slot 110 and the corresponding setting of bending skewed slot 210, when patrix 10 and counterdie 10 were closed, this Bending punch 11 and activity entered to pass through between son 21 negative angle skewed slot 110 and consist of angle bending groove 30 with bending skewed slot 210, are used for realizing the product bending.
It is worth mentioning that, above-mentioned angle is rushed part 12 and is fixed on patrix 10, one side of its lower end processes the second sliding bevel, this second sliding bevel and the first sliding bevel 211 are suitable, and be configured for realizing that the control activity enters the oblique Slipped Clove Hitch structure 40 that son 21 swings, the contact position that rushes the second sliding bevel of part 12 by angle is set is adjusted activity and is entered son 21 amplitude that swings, thereby come the size of control angle bending groove 30, i.e. adjustment activity enters spacing between the bending skewed slot 210 of sub-upper end and negative angle skewed slot 110, realizes the different negative angle bending and moldings of product.
The present embodiment in use, the bending product for the treatment of that only needs will bending be needed to be certain negative angle is placed in the die cavity of die 22 tops, then bending angle size required according to band bending product adjusted angle and rushed the second sliding bevel and the first sliding bevel 211 contact positions on part 12, can control its contact position by the spacing between controlling after patrix 10 and counterdie 20 matched moulds, also can rush part 12 upper-lower position height by adjusting angle, thereby realize the contact position of oblique 211 of adjustment the second sliding bevel and the first slip, reach the purpose of adjusting bending angle.
When the second sliding bevel moved down on the first sliding bevel 211 gradually, the spacing between bending skewed slot 210 and negative angle skewed slot 110 reduced gradually, thereby the bending angle that stamps out reduces gradually.In punching course, be the bending point at the turning, end of negative angle skewed slot 110, the trough rim of bending skewed slot 210 is the bending edges of product, thereby realizes the disposable punch forming of different bending angles or bending negative angle.
When the contact-making surface of the second sliding bevel and the first sliding bevel 211 is larger, when being matched moulds, the upper and lower mould spacing is less, at this moment, spacing between bending skewed slot 210 and negative angle skewed slot 110 is less, during punching press, be the bending point at the turning, end of negative angle skewed slot 110, under the effect of bending skewed slot 210, the bending edge break of product is crossed 90 degree and is inserted in negative angle skewed slot 110, thereby realizes the negative angle bending disposal molding of product.
based on above-mentioned, the present invention rushes part 11 by bending is set, activity enter son 21 with and between the angle bending groove 30 that forms, and rush part 12 by angle and control bending angle, not only realized the negative angle bending and molding of product, and realized the purpose of the disposable punching press negative angle bending and molding of product, and satisfied difference requires the machine-shaping of bending angle, its bending angle is easy to adjust, simple to operate, only need a punching press, avoided Multi-step forming and cause overproof, improved the machining accuracy of product, guaranteed the quality of product, satisfy the processing of the product of different bending angles, compare two or three times mould operations of general mould and want succinct easily row, be convenient to maintenance, cost is low, time saving and energy saving, improved the efficient of processing.
Above demonstration and described basic principle of the present invention and principal character and advantage of the present invention.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; that describes in above-described embodiment and specification just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
