Describe embodiment of the present utility model below with reference to accompanying drawings in detail, so that more clearly understand above-mentioned purpose and advantage with other of the present utility model.
Concrete embodiment
Referring to Fig. 1 and 2, the curved combination die of two-fold of the present utility model comprises a patrix 1 and a combination counterdie 26.Patrix 1 is configured to the below and is angled cutter type.Combination counterdie 26 comprises that a bending counterdie 5 and that can be slidably mounted on relatively together flattens counterdie 10.
As Figure 1-3, bending counterdie 5 have the bottom, to rectangular channel 12 under shed, that extend longitudinally perforation, and, upwardly extending screwed hole 13 12 substantial middle positions at described rectangular channel.One V-shaped groove 11 is formed on bending counterdie 5 tops, and the angle of V-shaped groove 11 is in 20-40 degree scope.Place, notch both sides at V-shaped groove 11 is formed with a groove 13 respectively.Each groove 13 is configured to move axially, can rolls but some small columns 3 (having drawn 4 among the figure) and a big column 2 can not be installed with moving radially.Below wherein some small columns 3 are installed in, and a big column 2 is installed in above some small columns 3, and contacts with each small column 3 rolling simultaneously.Each groove 13 is handled through polish, can rotate flexibly for 13 li at groove to guarantee each cylinder.In bending counterdie 5 vertical both sides one shrouding 4 (only having drawn half among Fig. 1) is installed respectively also, is moved axially to prevent small column 3 and big column 2.But the diameter φ 2.5 of small column 3, but and the diameter φ 6 of big column 2.Small column 3 and big column 2 chromium steel manufacturing, necessary heat treatment, making hardness number is HRC58-61.
As Fig. 1,2 and 4-5 shown in, flatten the base plate 14 that counterdie 10 has an integrally formed longitudinal extension, and from base plate 14 upwardly extending rectangular shaped slider bodies 15.Slide body 15 cooperates in the rectangular channel 12 that is installed in bending counterdie 5 slidably.Slide body 15 has a through hole 16 in the position corresponding with screwed hole 13 in the rectangular channel 12, and through hole 16 comprises that one has hypomere 17, the one diameters stage casing 18 more less than hypomere 17 diameters of a diameter, and the diameter epimere 19 bigger than stage casing 18 diameters.
Bending counterdie 5 and pressing counterdie 10 all require heat treatment, and hardness number is in the HRC40-50 scope, to improve the service life of mould.
Shown in Fig. 1 and 6-8, one regulates bolt 9 extends up through the through hole 16 that flattens in the counterdie 10, with screwed hole 13 engagements in the bending counterdie 5.And a spring 8 around regulate bolt 9, between the bottom of the bottom of the epimere 19 of through hole 16 and rectangular channel 12, so that bias voltage bending counterdie 5 upwards.
Shown in Fig. 1-5, comprise the upper surface 21 that is used to flatten the lower surface 20 of a bending counterdie 5 plate 27, correspondence parallel to each other and flattens the base plate 14 of counterdie 10 in the horizontal side (right side among the figure) of the upright slide body 15 that flattens counterdie 10.And have a right angle groove 22 away from the side (right side among the figure) of rectangular channel 12 at the lower surface 20 that flattens counterdie 10, so that when flattening plate 27, prevent the outside slippage of plate 27.Adjusting bolt 9 is used for regulating the distance between lower surface 20 and the upper surface 21, so that place the plates that have been bent into 30 degree when flattening operation.
As shown in Figure 4, the upper surface 21 of the base plate 14 of pressing counterdie 10 is parallel with the lower surface 23 of conduct first datum level of base plate 14, and this upper surface 21 is vertical with a horizontal side surface 24 of conduct second datum level of the described upright slide body 15 that flattens counterdie 10.
As Figure 1-3, the both lateral sides of bending counterdie 5 is formed with groove 25 respectively.The two piece filler rods 6 longer than combination counterdie 26 longitudinal lengths are chimeric respectively and be fixed on by screw or other means in the groove 25 of each bending counterdie 5 both sides of at least two groups, thereby described at least two groups combination counterdie 26 is longitudinally linked together.Thereby will make up the specification that counterdie is combined into different length, as 800mm, 1600mm, 2400mm, 3200mm etc., for use in the plate of processing different length.
Patrix 5 and bending counterdie 5 can be formed bender, and bending counterdie 5 and pressing counterdie 10 can be formed flattening die.
The operation of the curved combination die of two-fold of the present utility model can be referring to Fig. 6-8.As shown in Figure 6, in bending first time process, the flat plate 27 that a usefulness symbol A is represented is positioned on the V-shaped groove 11 of bending counterdie 10.When patrix 1 moves downward, contact plate 27 is when pressing down, the lower surface of plate 27 rolls with notch big column 2 and contacts, and along with patrix 1 descends, small column 3 is holding in the palm big column 2, because patrix 1 is downward, big column 2 rotates, and plate 27 is along with the rotation of big column 2 is bent downwardly, and patrix 1 returns after dropping to the requirement degree of depth, the bending process finishes, and forms the plate of representing with symbol B 27.
As shown in Figure 4, after finishing 30 degree bendings for the first time, will fill in by the lower surface 20 of bending counterdie 5 and flatten in the pressing notch that the upper surface 21 of the base plate 14 of counterdie 10 forms with the plate 27 that symbol B represents.When patrix 1 moves downward, contact with bending counterdie 5, bending counterdie 5 is moved downward, plate is flattened the two-layer plate of representing as with symbol C 27.Patrix 1 is replied upwards then, and bending counterdie 5 moves upward under the spring force effect of spring 8, makes plate be convenient to take out.
At last, as shown in Figure 8, will be positioned on the V-shaped groove 11 of bending patrix 5 with the double-deck plate 27 that symbol C represents, patrix 1 moves downward the precalculated position, finishes 90 degree bendings of double-deck plate, as the plate of representing with symbol D 27.
