Description
Technical field
The utility model belongs to technical field of mold, and specifically, particularly one is turned round for punching press automobileThe pneumatic type mould of power beam.
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 is to provide a kind of easy operating, is convenient to distinguish right and leftTo the pneumatic type mould for punching press torsion beam of automobile.
The technical solution of the utility model is as follows: a kind of pneumatic type mould for punching press torsion beam of automobile, bagDraw together die holder, insert, tapered wedges and mandrel, it is characterized in that: the two ends, left and right at described die holder are symmetrical arrangedDie cavity, these two die cavities are connected by translot, are fixedly installed multiple edges of splicing successively in described translotPiece, offers the groove that left and right connects on respectively inserting, it is straight-through that all grooves of inserting splice one of composition successivelyForming tank; In each die cavity of described die holder, be equipped with tapered wedges, the tapered wedges of the right and left is symmetrical,Described tapered wedges is connected with the piston rod of cylinder, and cylinder is installed in die cavity, in the opposite end of two tapered wedgesBe provided with mandrel, mandrel fixes with corresponding tapered wedges, and mandrel can stretch in forming tank, on the left sideOn the end face of a mandrel, be formed with convex closure, this convex closure is near the right side of corresponding tapered wedges;
Four angles place at described die holder end face is provided with column, and this column is cylinder, and four root posts divide by rectangleCloth, lower end and the cushion block of each column fix, 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, every group of connecting plate is divided into two of front and back, fourBy the rectangular distribution, described connecting plate is elongated rectangular shape to piece connecting plate, and the upper end of this connecting plate has strip hole,Projection laminating on lower end and the die holder of connecting plate is fixing;
Both sides, front and back at described die holder left end are symmetrically arranged with gathering sill, and the both sides, front and back of die holder right-hand member are also rightClaim to be provided with gathering sill, by the rectangular distribution, and gathering sill is " U " shape to four gathering sills.
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.
Column is arranged at four angles of die holder end face, and it is firm that this column is installed on die holder, in the time that mould does not useWork to support patrix, and support the good stability of patrix. Four connecting plates on die holder are in carryingWhen counterdie, play connection fastening, after upper and lower mould matched moulds, the strip hole of connecting plate upper end wears bolt and upperMould fixes, and upper and lower mould connection is firm like this, can not occur loosening or come off when carrying. On die holder fourGathering sill plays guiding patrix, and gathering sill is " U " shape, suitable mutually with the guide pad of corresponding setting on patrixJoin, make the utility model and Ccope closing machine faster, 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, implement easily, simple in structure, compact,Height dimension is little, and moulding torsion beam is easy and simple to handle, and workman's labour intensity is little, and production efficiency is high, and becomesTorsion beam identification left and right directions after type is easy, and in subsequent handling, torsion beam location is convenient, can not turn roundPower beam puts back.
