Description
Technical field
The invention belongs to technical field of mold, specifically, the particularly two-way air-cylinder type of one automobile-used tubulose V-type torsion beam mould.
Background technology
Torsion beam is the vitals on automobile, and Main Function is the bob of balance left and right wheels, to reduce rocking of vehicle, keeps the steady of vehicle.V-type torsion beam is stamped to form by the blank of circular tube shaped, and Sheet Metal Forming Technology is first one time punching molded inside and outside two V-type faces, then swollen type port shape at twice.Chinese patent ZL201410142309.4 discloses a kind of car tubulose V-type torsion beam Sheet Metal Forming Technology on July 30th, 2014, and specifically disclose mould and expanding die, this Sheet Metal Forming Technology is mould therefor complex structure not only, height dimension is large, forming operation is loaded down with trivial details, production efficiency is low, and shaping after product be left and right symmetrical part, be difficult to distinguish left and right directions in follow-up laser cutting operation, easy generation part puts back, there is deficiencies such as distinguishing left and right directions difficulty, waste time and energy in part location, greatly reduce cutting efficiency thus.In addition, the torsion beam processed, when welding with other part, also needs artificial careful difference left and right directions, to confirm position while welding, had both added the labour intensity of workman, and again reduced welding efficiency.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of two-way air-cylinder type automobile-used tubulose V-type torsion beam mould being easy to operate, be convenient to distinguish left and right directions.
Technical scheme of the present invention is as follows: a kind of two-way air-cylinder type automobile-used tubulose V-type torsion beam mould, comprise die holder, insert, tapered wedges and mandrel, it is characterized in that: die holder passes through casting, die cavity is symmetrical arranged at the two ends, left and right of described die holder, these two die cavities are connected by translot, arrange multiple insert of splicing successively at described translot internal fixtion, each insert is offered the groove that left and right is through, the groove of all inserts splices the straight-through forming tank of composition one successively; Tapered wedges is equipped with in each die cavity of described die holder, the tapered wedges of the right and left is symmetrical, described tapered wedges is connected with the piston rod of cylinder, cylinder is installed in die cavity, be provided with mandrel in the opposite end of two tapered wedges, mandrel fixes with corresponding tapered wedges, and mandrel can stretch in forming tank, the end face of an on the left side mandrel is formed with convex closure, and this convex closure is near the right side of corresponding tapered wedges;
Be provided with column at four angles place of described die holder end face, this column is cylinder, and by the rectangular distribution, lower end and the cushion block of each column fix four root posts, and described cushion block is fixedly connected with die holder by bolt;
At the two ends, left and right of described die holder, one group of connecting plate is respectively set, often organize connecting plate and be divided into two pieces, front and back, by the rectangular distribution, described connecting plate is elongated rectangular shape to four pieces of connecting plates, the upper end of this connecting plate has strip hole, and the projection on the lower end of connecting plate and die holder is fitted fixing;
Be symmetrically arranged with gathering sill on the both sides, front and back of described die holder left end, the both sides, front and back of die holder right-hand member are also symmetrically arranged with gathering sill, and by the rectangular distribution, and gathering sill is " U " shape to four gathering sills; Three inwalls of each described gathering sill are all pasted with wearing plate, and wearing plate is steel plate, and wherein two pieces of wearing plates parallel, and perpendicular to the 3rd piece of wearing plate, described wearing plate is fixed by sunk screw and die holder.
Adopt above technical scheme, by tapered wedges, cylinder arrangement in die cavity, and insert is arranged in groove, while simplification structure, greatly reduces overall height dimension, has saved die cost.When shaping torsion beam, first pipe blank is put into forming tank, then the cylinder action of the right and left is controlled, make two tapered wedges towards the motion of relative direction, the mandrel on each tapered wedges stretches in the corresponding end of pipe blank, and the pressure head then controlling press drives patrix descending, the punch forming of torsion beam can be realized, whole process is few, is easy to operation, effectively improves production efficiency.
Column is arranged at four angles of die holder end face, and it is firm that this column is installed on die holder, plays a part to support patrix, and support the good stability of patrix when mould does not use.It is fastening that four pieces of connecting plates on die holder play connection when carrying upper and lower mould, and after upper and lower mould matched moulds, the strip hole of connecting plate upper end wears bolt and patrix fixes, and it is firm that such upper and lower mould connects, and can not occur to loosen or come off during carrying.Four gathering sills on die holder play a part guide patrix, gathering sill is " U " shape, and the guide pad that arrange corresponding on patrix is suitable, make the present invention and Ccope closing machine faster, accurate.Arrange three pieces of wearing plates in gathering sill, such die holder does not directly contact with patrix, effectively can prevent wearing and tearing; Wearing plate selects steel plate, and selection is convenient, and wearability is good, and cost is low; Wearing plate and gathering sill inwall paste merga pass sunk screw and fix, wearing plate easy accessibility, and the fixing of installation is good, and are conducive to changing wearing plate.
Due to left side mandrel having convex closure, after such torsion beam is shaping, its left end correspondingly has projection, this projection plays a part to identify direction on the one hand, distinguish with the shape on the right of torsion beam and come, be conducive to follow-up laser cutting and welding sequence distinguishes left and right directions, prevent part from putting back, both reduce the labour intensity of workman, further increase working (machining) efficiency again; On the other hand, the projection that torsion beam left end is formed can also play location, so that workpiece is quickly and reliably located in laser cutting operation.
Flexible, smooth and easy in order to make tapered wedges move, in described die cavity, be provided with two, front and back guide rail, these two guide rail separations are in the both sides of cylinder, and guide rail parallels with cylinder, and described tapered wedges is coordinated with the slide of two in same die cavity by slide block.
For the ease of carrying time lift, the left side and right side of described die holder respectively arrange two hangers, these four hangers in same level by the rectangular distribution.
Described hanger is cylinder, and one end and the die holder of this hanger fix, and are formed with annular boss at the other end of hanger.Above structure on the one hand hanger moulding is simple, and be easy to processing and fabricating, intensity is good; On the other hand, when lifting, hook is spacing by the end face of annular boss and die holder, landing can not occur, and hoisting process safely, reliably.
Beneficial effect: the present invention is skillfully constructed, reasonable in design, height dimension is little, shaping torsion beam is easy and simple to handle, and the labour intensity of workman is little, and production efficiency is high, and the torsion beam identification left and right directions after shaping is easy, in subsequent handling, torsion beam location is convenient, torsion beam can not occur and put back.
