The fixed dummy block of the aluminum profile extruder is characterized in that the angle of the inner conical surface of the expansion ring and the angle of the conical surface of the conical gasket are 48 to 51 degrees. The fixed dummy block of the aluminum profile extruder has the benefits as follows: the angle of the fixed dummy block is reduced, so that an expansion component force generated by the same extrusion force is increased; the expansion deflection of the fixed dummy block can be controlled by adjusting the gap between the conical gasket and the fixed pedestal; and the deformation work zone of the expansion is prolonged, the deformed part of the expansion ring is deepened and thinned, the expansion ring is easy to deform, a proper gap can be guaranteed between the expansion ring and an extrusion cylinder, and the service life of the expansion ring is prolonged.

Description

The fixation extrusion pad of aluminium section bar extruder
Technical field
The utility model belongs to aluminium and aluminium alloy extruded processing, relates in particular to a kind of fixation extrusion pad of improved aluminium section bar extruder.
Background technology
The extruding pad is one of compression tool very important in the extruder.During extruding, an extruding pad is arranged between pressure ram and the blank aluminium ingot, in order to transmit extruding force and sealing recipient, thereby avoid reducing intensity, prevent from directly to cooperate quick-wearing and distortion to cause whole pressure ram to be scrapped with recipient because of the extruding rod end owing to pressure ram directly contacts with the high temperature billet.In conventional extruder, generally must be independent of pressure ram 23 movable dummy blocks are set, there be not any connection with pressure ram, movable dummy block recycles by a pad EGR.At present, a kind of unitary fixed dummy block that is connected on the pressure ram of the existing use in market, it is the expanding mouth type overall structure, and the major defect of existence is that expansible reducing part is an one with connector, and the cross section is excessively unexpected, the root rigid constraint is bigger, the distortion of stressed back is inhomogeneous, and causes easy damage, and service life is short, and be whole the damage and integral replacing, use cost is higher.
A kind of aluminium extruding machine of the disclosed patent application of Taiyuan Heavy Machinery Group Co., Ltd (200410012520.0) comprises the dummy block connector, screw rod, spring, tensioner ring and the cone pad that are contained on the pressure ram with tensioner ring formula fixation extrusion pad; In the mesopore of dummy block connector spring is housed, screw rod links to each other the dummy block connector with the cone pad, and tensioner ring is contained in outside the dummy block connector, and the tensioner ring inner conical surface matches with the conical surface of cone pad, and the afterbody of tensioner ring matches with connector; Tensioner ring and connector are separated; It is characterized in that: also be provided with the ring pad that is contained between pressure ram and the tensioner ring, the ring cushion cover is contained on the cylindrical of dummy block connector, the mating part of the mesopore of connector and cone pad is provided with the key that prevents that the cone pad from rotating, key is fixed on the cone pad by screw, on ring pad and connector, be provided with the pilot hole of symmetrical distribution, the cylindrical of connector afterbody is provided with annular anticreep groove, passes the pressure ram cross section by a holding screw and is positioned in the groove.
Under the non-squeezed state, allow the bigger gap dummy block recipient of can non-resistance ground freely coming in and going out between tensioner ring head outer diameter and the recipient endoporus.When extruding, dummy block is not separated from recipient always, and tensioner ring end face and cone pad push billet simultaneously, and under the effect of axial compression power, the conical surface compressing tensioner ring of cone pad makes it to produce radial elastic dilation.The radial-deformation of tensioner ring is limited by the movement travel of cone pad, makes the gap that forms appropriateness between tensioner ring after the expansion and the recipient endoporus, reaches the purpose that stops material to flow backwards.After the press off-load, the cone pad returns to the home position under the reaction of spring, tensioner ring then automatically bounce-back shrink, return to freely the come in and go out state of recipient of dummy block non-resistance that allows.Bringing up again very much four fixed press pads supplying with manufacturer wherein ruptures in 3 productions.Slit between fixation extrusion pad and the recipient is excessive, and the aluminium that overflows in extruding is produced is more.The fixed press mat structure does not have than complexity and dish spring system should effect, makes to produce to be affected.
The utility model content
The utility model is in order to overcome deficiency of the prior art, a kind of fixation extrusion pad of aluminium section bar extruder to be provided, and the pad thickening has solved breakage problem; Reduce to fill up the conical surface angle of tensioner ring inner conical surface and cone pad, tensioner ring can be expanded in extruding is produced put in place, the aluminium that overflows is less; The dilatancy amount of fixation extrusion pad can be controlled by cone pad and the fixedly adjustment of the working clearance between the base.
The utility model is achieved through the following technical solutions for achieving the above object, and a kind of fixation extrusion pad of aluminium section bar extruder comprises the fixedly base, screw rod, tensioner ring and the cone pad that are contained on the pressure ram; Screw rod fixedly base links to each other with the cone pad, and tensioner ring is contained in fixedly outside the base, and the tensioner ring inner conical surface matches with the conical surface of cone pad, and the afterbody of tensioner ring matches with fixing base ladder platform; Tensioner ring and fixedly base be separated; It is characterized in that: the conical surface angle of described pad tensioner ring inner conical surface and cone pad is 48-51 °.
The deformation operation band of described tensioner ring extends to 1/3 of tensioner ring thickness.
Described cone pad and fixedly be provided with the working clearance between the base end face.
Described cone pad and fixedly be provided with the anti-rotation round pin between the base end face.
Beneficial effect: the angle of fixed press pad reduces, and the expansion component that identical extruding force is produced increases.It is easily deformable that the dilatancy of fixation extrusion pad is partly deepened attenuate.It is the easily deformable cost of having saved again that the dilatancy of fixation extrusion pad part is separated with fixing base, damage only be tensioner ring.The dilatancy of fixation extrusion pad puts in place, but the deflection of unit length has reduced and improved service life.The dilatancy amount of fixation extrusion pad by pad and fixedly the gap adjustment between the base can control.The deformation operation band of tensioner ring prolongs, and can make tensioner ring easily deformable, and can guarantee the suitable gap between itself and the recipient, the service life of also having improved tensioner ring.
