Fig. 2 is device structure schematic diagram of the present utility model.
Mark among the last figure: material loading chassis 1, stock shelf 2, material loading side bitting clamp 3, plate pipeline 4, punching parts 5, blanking side bitting clamp 6, blanking chassis 7, blanking rack 8, cutting area auxiliary clamp 9, cutting part 10, dust arrester 11, centralising device 12.
The specific embodiment
With reference to figure 1, its shown variable cross-section longeron need cut two procedures through punching and an end-grain cutting and be processed to form.Dotted portion is cutting zone.
With reference to figure 2, on the rectilinear direction of plate pipeline 4, be disposed with stock shelf 2, punching parts 5, blanking rack 8 and cutting part 10.On plate pipeline 4, be provided with material loading side bitting clamp 3, blanking side bitting clamp 6 and cutting area auxiliary clamp 9 along rectilinear direction.In the front of punching parts 5, centralising device 12 is installed also.
Adding man-hour, at first with plate piling to be processed to material loading chassis 1, and material loading chassis 1 reached stock shelf 2 positions, herein, by devices such as magnechucks plate is delivered on the feeding roller table of plate pipeline 4.Then, material loading side bitting clamp 3 promotes plates and advances, and cooperates with centralising device 12 and to finish plate and locate.Centralising device 12 can be motor-driven feed screw apparatus, and perhaps common centralising device on other market is introduced in its concrete operation principle and this specification of structure no longer in detail.Back, location material loading side bitting clamp 3 clamps plate, the 5 beginning punch works of punching parts.Punching finishes, and material loading side bitting clamp 3 is return, and blanking side bitting clamp 6 continues sheet feed to cutting area, cutting area auxiliary clamp 9 clamps plate, cutting part 10, and for example CUT begins cutting, the side bitting clamp of blanking simultaneously 6 is return, and prepares the punch work of next plate.The requirement that another piece plate cut when the satisfied plate of the length of preferred plate pipeline 4 carried out punching, namely be not less than two automobile variable cross-section longeron plates length and, current plate is when cutting work station is carried out cutting processing, next plate begins punching processing again, needn't wait for that current plate finishes after the cutting again to next plate punching, and so forth, production efficiency height.After plate cutting is finished, at blanking rack 8 places with the plate stacking to blanking chassis 7, the plate that processes is transported.Be to purify working environment, and the flue dust of avoiding producing in the cutting process influence machining accuracy, preferably near the dust arrester 11 that installation can siphon away the flue dust of place, the operating position generation of cutting part 10 cutting part 10.Because stock shelf 2, punching parts 5, blanking rack 8 and cutting part 10 are along the rectilinear direction setting of plate pipeline, in whole process, only need material loading side bitting clamp 3 to cooperate with centralising device and carry out the plate location No. one time, after punching finishes, blanking side bitting clamp 6 directly continues plate to march forward to a segment distance, can cut the directly blanking of cutting back.In whole process, plate all is to carry out the location, edge by clamp, need not blanking device plate is moved on the other Cutting platform from plate pipeline 4, also need not to carry out the secondary location of plate, so device structure is simpler.Process, only carry out one-time positioning for straight line, dedusting is even more important, otherwise the accumulation meeting of flue dust directly influences the operation of clamp, thereby influences precision.
