Description

For the pneumatic type shaping mould of torsion beam of automobile

Technical field

The utility model belongs to technical field of mold, specifically, particularly a kind of for torsion beam of automobilePneumatic type shaping mould.

Background technology

Torsion beam is the vitals on automobile, and Main Function is the bob of balance left and right wheels, to subtractRocking of little vehicle, keeps the steady of vehicle. V-type torsion beam is stamped to form by the blank of circular tube shaped, presserSkill is first one time punching molded inside and outside two V-type faces, then swollen type port shape at twice. Chinese patent ZL201410142309.4 disclose a kind of car tubulose V-type torsion beam Sheet Metal Forming Technology on July 30th, 2014,And specifically disclosing mould and expanding die, this Sheet Metal Forming Technology is mould therefor complex structure not only, highlySize is large, and forming operation is loaded down with trivial details, and production efficiency is low, and product after moulding is left and right symmetrical part, rear, easily there is part and put back in impalpable left and right directions in continuous laser cutting operation, exists and distinguish right and leftThe deficiency such as waste time and energy to difficulty, part location, greatly reduces cutting efficiency thus. In addition, processTorsion beam in the time welding with other part, also need artificial careful difference left and right directions, with confirm welderingStitch position, both increased workman's labour intensity, reduced again welding efficiency.

Utility model content

Technical problem to be solved in the utility model be to provide a kind of simple in structure, easy operating forThe pneumatic type shaping mould of torsion beam of automobile.

The technical solution of the utility model is as follows: a kind of pneumatic type shaping mould for torsion beam of automobile, comprisesDie holder, insert, tapered wedges and mandrel, it is characterized in that: the two ends, left and right at described die holder are symmetrical arranged typeChamber, these two die cavities are connected by translot, are fixedly installed multiple inserting of splicing successively in described translot,On respectively inserting, offer the groove that left and right connects, all grooves of inserting splice a straight-through moulding of composition successivelyGroove; In each die cavity of described die holder, be equipped with tapered wedges, the tapered wedges of the right and left is symmetrical, described inTapered wedges is connected with the piston rod of cylinder, and cylinder is installed in die cavity, all establishes in the opposite end of two tapered wedgesBe equipped with mandrel, mandrel fixes with corresponding tapered wedges, and mandrel can stretch in forming tank, one of on the left sideOn the end face of mandrel, be formed with convex closure, this convex closure is near the right side of corresponding tapered wedges;

Two row's limited blocks before and after being provided with at the middle part of described die holder end face, this two rows limited block is lived apart in forming tankBoth sides, equate with the distance between two adjacent limited blocks in row, described limited block is up-small and down-big two sectionsThe hollow short column of formula, the center of limited block wears screw and die holder is fixed; On the both sides, front and back of described die holder left endBe symmetrically arranged with gathering sill, the both sides, front and back of die holder right-hand member are also symmetrically arranged with gathering sill, and four gathering sills are pressedDistributed rectangular, and gathering sill is " U " shape.

Adopt above technical scheme, tapered wedges, cylinder arrangement, in die cavity, be arranged in groove and insert,In simplified structure, greatly reduce overall height dimension, save die cost. At moulding torsionWhen beam, first pipe blank is put into forming tank, then control the cylinder action of the right and left, make twoIndividual tapered wedges is towards relative direction motion, and the mandrel on each tapered wedges stretches in the corresponding end of pipe blank,Then the pressure head of controlling press drives patrix descending, can realize the punch forming of torsion beam, whole process workOrder is few, and easy operating has effectively improved production efficiency.

Two row's limited blocks of die holder end face play restriction patrix stroke, to guarantee security and torsion beamThe uniformity of moulding. Limited block is the up-small and down-big hollow short column of two-part, and moulding is simple, and processing and fabricating holdsEasily, the screw that limited block wears by center is connected with die holder, be not only connected firmly, reliably, and screwDo not expose, can not affect the function of limited block. Four gathering sills on die holder play guiding patrix, leadBe " U " shape to groove, suitable with the guide pad of corresponding setting on patrix, make the utility model and Ccope closing machineFaster, accurate.

Owing to having convex closure on the mandrel of the left side, after torsion beam moulding, its left end correspondingly has projection like this,This projection plays identification direction on the one hand, comes with the shape difference on torsion beam the right, is conducive to follow-upLaser cutting and welding sequence distinguish left and right directions, prevent that part from putting back, both reduced workman's laborFatigue resistance, has further improved again working (machining) efficiency; On the other hand, the projection that torsion beam left end forms is all rightPlay location, so that workpiece is quickly and reliably located in laser cutting operation.

In order to make tapered wedges motion flexible, smooth and easy, two guide rails before and after being provided with in described die cavity, these twoGuide rail is lived apart in the both sides of cylinder, and guide rail parallels with cylinder, and described tapered wedges is by slide block and same typeTwo guide rails in chamber are slidably matched.

Time lift for the ease of carrying, on the left side of described die holder and right side, respectively arrange two and hangEar, 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, at the other end one bodily form of hangerBecome to have annular boss. Above structure on the one hand hanger moulding is simple, is easy to processing and fabricating, and intensity is good; AnotherAspect, in the time of lifting, hook is spacing by the end face of annular boss and die holder, and landing, hoisting process can not occurSafety, reliable.

Beneficial effect: the utility model is skillfully constructed, reasonable in design, to implement easily, height dimension is little, rawProduct cost is low; Easy and simple to handle by the utility model moulding torsion beam, workman's labour intensity is little, produces effectRate is high, and torsion beam after moulding identification left and right directions is easy, and in subsequent handling, torsion beam location is convenient,Torsion beam can not occur to put back.
