Description
Technical field:
The utility model belongs to the mould applications of auto parts machinery, particularly relates to a kind of oil cooler water fender blanking bender.
Background technology:
The die of the oil cooler water fender blanking bender of prior art is provided with groove, the groove surface of groove one end becomes one 144 slope with the surface of die, can only carry out moulding to the single-chip microcomputer oil cooler water fender that has cut, and once can only part of moulding; And the shape of the punch of shearing die is only to be provided with the groove identical with shape of product on one side, once can only obtain the semi-finished product that a slice is used for bending so shear; Moreover owing to be that oil cooler water fender blanking is carried out monolateral moulding and one-way shear, then the two ends discontinuity uneven wear of mould is serious, and the flexible difficulty of the part after the moulding reaches the requirement of drawing.Therefore production efficiency is low, hold die life, product percent of pass is low and generate this height.
The utility model content:
The oil cooler water fender blanking bender that the technical problems to be solved in the utility model is a kind of production efficiency height, die life is long, product percent of pass is high and production cost is low.
The utility model overcomes the above problems used technical scheme: a kind of oil cooler water fender blanking bender with following structure is provided, it comprises upper bolster, die shoe, punch and die, the upper surface of described upper bolster is provided with die shank, described punch is connected the lower surface of upper bolster, be provided with the punch limiting plate around the described punch, the punch limiting plate is connected with upper bolster, described die is connected with die shoe, it also comprises the bending plate that flexibly connects with the punch limiting plate, the looking up of described punch is shaped as square block and is symmetrically distributed with two grooves that form by two circular arcs of a vertical curve smooth connection along the center line of its left and right directions, the central angle of described circular arc correspondence is 90 degree, be provided with elastic device between bending plate and the punch limiting plate, the centre of described bending plate is provided with groove, the centre of described groove is provided with the through hole that matches with punch, have between the lower surface of groove surface two ends and bending plate one with the angled slope of groove surface, described die is provided with the through hole that matches with punch.
Described by being provided with the die shank pin between bolted upper bolster and the die shank.
The described bending plate that flexibly connects with the punch limiting plate is meant that bending plate and the bolt that is tightened on the punch limiting plate are slidingly matched.
Corner angle all on the described punch are arc chord angle.
Be provided with the die backing plate between described die and the die shoe, be equipped with the through hole that cooperates with punch on described die backing plate and the die shoe.
Be provided with shop bolt between described punch limiting plate and the upper bolster, be equipped with position-limitting pin between described die and the die backing plate and between die shoe and the die backing plate.
The angled slope of described and groove surface is meant the slopes that become 140～148 degree with groove face.
After adopting above structure, the utility model compared with prior art, because the looking up of punch is shaped as square block and is symmetrically distributed with two grooves that form by the circular arcs of two central angles of a vertical curve smooth connection, 90 degree along the center line of its left and right directions, and set up bending plate, the centre of bending plate is provided with groove, have between the lower surface of groove surface two ends and bending plate one with the angled slope of groove surface, then when in the process of upper and lower mould closure, bending plate at first acts on the sheet material, makes the groove and the slope moulding along bending plate of sheet material; Bending plate makes rubber blanket distortion under the effect of the reaction force of sheet material subsequently, thereby punch is affacted on the sheet material, along with closing of punch and die closed, sheet material sheared from the centre two finished products.So be to carry out at the sheet material two ends simultaneously during bending, bending plate and product are stressed evenly; Sheet material is pressed in the groove of bending plate during shearing, and die head is stressed, and evenly product is not yielding, thereby die life is long, product percent of pass is high and production cost is low; Moreover two parts of one-shot forming, the production efficiency height.Therefore the utility model production efficiency height, die life is long, product percent of pass is high and production cost is low.
As further improvement, described die is provided with a plurality of first pin stop, the die backing plate is provided with second pin stop, the hole of matching with first pin stop and second pin stop on the described bending plate, because the effect of pin stop, make sheet material the location more accurately, sheet material is more stable during moulding, thereby the finished size after improving the qualification rate of product and making moulding is more accurate.
