Step 3: build And of Varying Depth roller die formation system, that is: by sheet material throughput direction, set gradually decoiling equipment 1, pay-off 2, uniform section roll forming device 3, And of Varying Depth roller die building mortion, shearing device, drawing mechanism and palletizing apparatus;
For And of Varying Depth roller die building mortion, shaping roll stacks 5 is set directly over bed die 4, that is: make the main forming roll 5-1-1 of each forming rolls 5-1 be positioned at directly over the grooving 4-1 of bed die, wherein, the axial length of main forming roll 5-1-1 and the well width of grooving 4-1 suitable; Be set as shape roll stacks 5 to be made up of n forming rolls 5-1, its shape angles is respectively from the 1st passage to the n-th passage: α 1, α 2 ... α n;
Step 4: then, first carries out uncoiling by the sheet material of decoiling equipment 1 pair of rolling; By pay-off 2, the sheet material after uncoiling is transported to uniform section roll forming device 3 and carries out uniform section shaping, sheet material forming is end to end multiple U-shaped components 10 by uniform section roll forming device 3 successively, by shaping sequencing, be designated as 1U shape component, 2U shape component successively Wherein, each U-shaped component includes the plane of structure being positioned at bottom and the left surface and the right flank that are positioned at the plane of structure left and right sides; The width of U-shaped component is n1, and length is L1;
Step 5: host computer controls shaping roll stacks 5 lifting by forming rolls group motion, makes forming rolls group 5 be separated with bed die 4; 1U shape component after step 4 is delivered in the 1st shaping pilot trench of bed die 4;
Step 6: PC control forming rolls group 5 towards the motion of 1U shape component, that is: controls shaping roll stacks 5 and carries out x to motion; When the forming rolls of the 1st passage moves to directly over 1U shape component head position P1, host computer on the one hand, shaping roll stacks 5 is driven to carry out x to moving along 1U shape component, on the other hand, host computer also starts to carry out independent regulable control to the forming rolls of each passage in the position of z-axis, the forming rolls of each passage is drawn close to bed die 4, and near the grooving of bed die 4 and along the orbiting motion of bed die 4 in xz plane, be the shape for hat state meeting specific forming curve by the correspondence position bending of 1U shape component, concrete wrap direction is:
Suppose the forming rolls for any i-th passage, when it moves to the Pi position of 1U shape component, Pi is the x-axis coordinate that the forming rolls of the i-th passage moves to; Host computer reads Pi value in real time, and meanwhile, host computer reads specific forming curve, obtains the depth value z of shape for hat part in this position that be formed, if z value is zi; Groove outer geometric locus again due to the 1st shaping pilot trench is consistent with the forming curve of the shape for hat part that is formed, that is: the groove outer height of the 1st shaping pilot trench corresponding to Pi position of 1U shape component is also zi, therefore, when the forming rolls of the i-th passage drops to zi height, the groove outer of the 1st shaping pilot trench effect under, left redundant roll 5-1-2 by the outside bending of left surface at the Pi position of U-shaped component, wherein, bending angle equals the shape angles α i of this passage, and bending position is the position of zi; Meanwhile, right redundant roll 5-1-3 is by the outside bending of right flank at the Pi position of U-shaped component, and wherein, bending angle equals the shape angles α i of this passage, and bending position is the position of zi; Be the degree of depth by the Pi position bending of 1U shape component be thus zi, shape angles is the state of α i;
Step 7: the forming rolls of the 1st passage is moved to 1U shape component tail position P0 and after carrying out bending and forming to 1U shape component tail position P0, if now obtain the 1 half shape for hat component;
Then, by forming rolls group 5 lifting, forming rolls group 5 is separated with bed die 4; And control shaping roll stacks 5 along x to carrying out counter motion, make the forming rolls of the 1st passage be positioned at directly over the head end of the 2nd shaping pilot trench; Then, the 1 half shape for hat component is transported to the 2nd shaping pilot trench, and is positioned at after the 1 half shape for hat component and with the 1 half shape for hat component continuous print 2U shape component and is transported to the 1st shaping pilot trench;
Then, decline shaping roll stacks 5, meanwhile, on the one hand, host computer drives shaping roll stacks 5 at x to the head end moving to the 1st shaping pilot trench from the 2nd shaping pilot trench; On the other hand, host computer also starts to carry out independent regulable control to the forming rolls of each passage in the position of z-axis, the forming rolls of each passage is made to be the shape for hat state meeting the component setup parameter that is formed successively by the correspondence position bending of component, detailed process is: be the 1st shape for hat component by the 1 half shape for hat component forming, the final shape for hat component obtained after the 1st shape for hat component is shaping; Be the 2 half shape for hat component by 2U shape component forming;
When shaping roll stacks 5 moves to the head end of the 1st shaping pilot trench, continue feeding component length that is formed again, 3U shape component is made to be transported to the 1st shaping pilot trench, and the 2 half shape for hat component is transported to the 2nd shaping pilot trench, and the roll stacks 5 that is shaped turns back to directly over the 2nd shaping pilot trench, each U-shaped component forming is constantly shape for hat component by so constantly circulation;
In the utility model, for the U-shaped component obtained that formalizes through uniform section forming unit, by the independent z value controlling each forming rolls group in shaping roll stacks in real time, be hat by each cross section of U-shaped component in different depth bending, but, for each cross section of U-shaped component, all by the effect of each passage forming rolls, be configured as 90 degree in certain depth, essence is a gradual change cross section forming process.
Such as, as shown in Figure 7, during for being provided with 5 passage forming rolls, the variable cross-section forming process schematic diagram in certain cross section of U-shaped component; As can be seen from Figure 7, this cross section of U-shaped component, first by the 1st passage forming rolls, through the effect of 1 passage forming rolls, makes the left surface of U-shaped component and right flank respectively to the position of outer bending to 20 °, obtains the state that shape angles is 20 °; Then, by the 2nd passage forming rolls effect, this cross section is formed into 40 °; By that analogy, according to this by the forming rolls of the 3rd passage to the 5th passage, finally this cross section of this U-shaped component is formed into 90 degree.
Step 8: the tail end of bed die exports each shape for hat component that step 7 obtains, and successively through shearing device, drawing mechanism and palletizing apparatus process, obtains multiple shape for hat component independently separated.
In sum, And of Varying Depth roller die building mortion, And of Varying Depth roller die formation system and manufacturing process that the utility model provides, have the following advantages:
(1) distance between every time forming rolls and bed die of forming rolls group is made independently to regulate, thus the effective roll forming difficult problem solving the not only dark but also narrow variable cross-section part of cross sectional shape.
(2) bed die is adopted, bed die is formed by multiple identical shaping pilot trench is end to end, and, the groove outer geometric locus of each shaping pilot trench is consistent with the forming curve of the shape for hat part that is formed, therefore, under the effect of bed die, can ensure the forming accuracy of part, the product quality that variable-section roll-bending is shaped is greatly improved.In addition, also there is the high advantage of production efficiency.
The above is only preferred embodiment of the present utility model; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should look protection domain of the present utility model.
