Abstract
The present invention relates to car door production process and apparatus, and is especially technological process and mold for binding edge of car frame edge. The outer door plate is bent and bound by means of the horizontal motion of slide block driven with the edge binding mold. The present invention has no need of replacing mold, short edge binding period, high production efficiency and high product precision.
Description
Technical field
The present invention relates to a kind of car door production process and device, especially the car door frame edge process of automobile and bound edge mould.
Background technology
At present; the bound edge of known arrangements for automotive doors frame all is to adopt single rocking arm wedge cam bound edge mould or 6 linkage bound edge moulds; the course of work of single rocking arm wedge cam bound edge mould is: with after-frame assembly outside plate one side behind the assembly welding on the profiling tire; patrix is descending; holding pad compresses the after-frame assembly; the wedge actuating cam makes jack knife turn left and the stile of after-frame outside plate folding is at 45 along fixing point; along with the continuation of patrix is descending; the wedge inclined-plane of cam contact stops, and through a transition region, this moment, spring retracted jack knife by force; get out of the way push type broach; by push type broach 45 ° of flangings are flattened inclusion, patrix returns, and cam mechanism playbacks through an idle stroke.The course of work of 6 linkage bound edge moulds is: with after-frame assembly outside plate one side behind the assembly welding on profiling jig, move on the hydraulic cylinder piston rod, the drive rocking bar clockwise rotates, connecting rod promotes to have the rocking bar of jack knife around fixing point rotation and the stile folding of after-frame outside plate is at 45, move on hydraulic cylinder piston rod continues, connecting rod retracts rocking bar, gets out of the way the rocking bar that has push type broach and by rocking bar 45 ° of flangings is flattened inclusions, hydraulic cylinder piston rod return, double rocking lever are driven in the wrong direction and are playbacked.The arts demand of this bound edge mould selects in operating process and changes many molds, and different moulds are finished the bound edge of different parts, can influence the precision of product when changing different mould.
Summary of the invention
The invention solves in the existing wrapping process needs to select mold exchange, reduces the deficiency of precision, and a kind of car door frame edge process and bound edge mould without a bound edge of die change is provided.
The technical solution adopted for the present invention to solve the technical problems is: a kind of car door frame edge process the steps include:
A, the inner panel of drawing and guide rail are carried out assembly welding on request;
B, the inner panel and the guide rail of assembly welding placed flanging outer sheet frame in, the position of centering locating hole is put in the counterdie of wrapping mold;
C, starting pressure equipment make patrix descending, and holding pad is pushed down group welding piece;
D, patrix continue descending, and the block hitting in the bound edge mould promotes slide block, and travel switch control oil cylinder promotes the oil cylinder slide block, and slide block curves introversion flanging less than 45 ° to the outside plate flanging by horizontal movement;
E, patrix are then descending, and slide block resets under the effect of extension spring, and the oil cylinder slide block keep-ups pressure static;
F, patrix go downwards to the end and are undertaken spacingly by limited post up and down, and the outside plate flanging flattens, and pressure rises to predetermined value, finishes bound edge.The assembly welding of inner panel and guide rail can carry out after bound edge is finished, if but inner panel and guide rail are not carried out necessary fixing, in the bound edge process, can be moved, change their relative position; Before bound edge, the group welding piece of inner panel and guide rail and outside plate can move mutually, therefore need position them, and the centering locating hole can improve the precision of car door frame edge position; Consider that the flanging of outside plate can be toppled over and can not produce bending toward the inboard for stressed reasonability, is less than 45 ° in middle angle bending; In order to prevent that outside plate from flattening the back bounce-back, patrix will stay for some time, and controls time of stop by pressure control switch, and patrix rises and resets when pressure reaches design load; The time of assembly welding can be placed on after bound edge finishes, but like this in the bound edge process, need control the position of inner panel and guide rail.
In order to keep the relative position of inner panel and guide rail, therefore, described inner panel and guide rail assembly welding mode are spot welding, and the pre-bent angle of outside plate flanging is 30～35 ° of introversions, and reset at patrix drift and the slide block of slide block are finished before interfering.Employing spot welding is very simple and convenient, and speed is also fast, can meet the demands again; What slide block was considered in first step angle bending control withdraws from space and the descending required angle of concora crush of finishing of patrix, adopts 30～35 °.
A kind of car door frame edge mould comprises upper die and lower die, wherein, be fixed with on the described patrix and the identical holding pad of the profile of group welding piece, patrix is provided with block hitting in inner panel one side, and slide block and block hitting fit and driven by block hitting, guide rail one side is provided with the oil cylinder slide block, and the oil cylinder slider tail is connected with oil cylinder.The effect of holding pad is to push down group welding piece, prevents to have at work displacement, influences the precision of bound edge; Consider the structure difference of different parts, in different ways, inner panel one side slide block, and guide rail one side is because the shape of guide rail own adopts the oil cylinder slide block, and the oil cylinder slide block needs the pressure that keeps certain at work.
The inboard of described block hitting is a curved surface, and the movement locus of curved surface and slide block matches, slide block and application of a surface, and slide block can promote motion in the horizontal direction by block hitting; The space that the size of oil cylinder slide block and guide rail form matches.Block hitting moves up and down, and the mobile driving slide block by curved surface moves horizontally; Be the flanging of the outside plate that guarantees rail-sides, the length of oil cylinder slide block is more than or equal to the height of guide rail, and the height of oil cylinder slide block is less than the height in the space that guide rail forms, and makes the oil cylinder slide block can enter into guide rail the inside smoothly, guarantees the bound edge length of outside plate.
Be anti-limited slip block and the interference of patrix drift, the extension spring of ining succession on the described slide block, slide block and block hitting are permanently connected to.Under the effect of extension spring, slide block closely contacts with block hitting, and when block hitting is descending all the time the curved surface profile along block hitting move.
As preferably, described patrix is provided with the stroke limit piece that matches with the travel switch of oil cylinder.The setting in motion time of stroke limit piece control oil cylinder, oil cylinder slide block distance is determined by oil cylinder stroke.
Be provided with limited post between the described upper and lower mould.Guarantee the distance that patrix is descending by limited post, guarantee the firm of car door bound edge.
The invention has the beneficial effects as follows: guarantee under the state of inner panel and guide rail, to realize bound edge simultaneously; More mold exchange has shortened the activity duration, has improved production efficiency; Holding pad that the use shape is coincide and the stop of patrix after flattening flanging have guaranteed the machining accuracy of car door frame,
