Abstract
A fixed expanding-ring pressing block for the squeezer of aluminium part is composed of main body with spring in its central hole, conic pad, screw bolt for connecting said conic pad with main body, expanding ring with front and back conic surface for maching with said conic pad, pressing rod, ring pad between pressing rod and expanding ring, etc.
Description
Technical field
The invention belongs to aluminium and aluminium alloy extruded manufacture field, specially refer to aluminium section bar ectrusion press tensioner ring formula fixation extrusion pad.
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 2～3 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.
U.S. Pat 005918498A discloses a kind of aluminium extrusion fixed bolster structure (DUMMY BLOCKCONSTRUCTION) that is used for, mainly by connecting main body, bolt, spring, wear-resisting elasticity tensioner ring and cone pad; In connecting main body endoporus is arranged, hole built-in spring, bolt will connect main body and link to each other with the cone pad, be provided with the pre-large post-small conical surface in tensioner ring, and the conical surface matches with the conical surface of cone pad; Respectively be provided with on being characterized in tensioner ring and being connected main body and protrude recessed interior external tooth, first tensioner ring internal tooth insert connect rotate mutually again behind the main body external tooth angle with tensioner ring be connected the main body connection.This fixed bolster structure is comparatively complicated, and manufacturing and processing technology are poor, and stress deformation is inhomogeneous, and the tensioner ring wall unevenness is even etc., and all very easy generation stress is concentrated in making and using, the easy especially fracture damage of tensioner ring in the use, and service life is shorter.
Summary of the invention
The object of the invention is improved at above the deficiencies in the prior art, a kind of pad circulatory system of having cancelled is provided, simplified the operating process of extruder system, reduce no extrusion cycle cycle time, simple and reasonable for structure, the Fast Installation dismounting, long service life, the aluminium extruding machine of enhancing productivity fills up with fixing the squeezing of tensioner ring formula.
Tensioner ring formula fixation extrusion pad technical scheme of the present invention is achieved in that
A kind of aluminium extruding machine comprises: be contained in dummy block connector, bolt, spring, tensioner ring and cone pad on the pressure ram with tensioner ring formula fixation extrusion pad; In the mesopore of dummy block connector spring is housed, bolt 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 mating part of the mesopore of connector and cone pad is provided with the key that prevents that cone from rotating, and 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 bigger gap between tensioner ring head outer diameter and the recipient endoporus, the dummy block recipient of can non-resistance ground freely coming in and going out.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.
A kind of aluminium extruding machine provided by the invention is fastened on the pressure ram with tensioner ring formula fixation extrusion pad, along with pressure ram forward-reverse together, plays the function of transmitting extruding force and sealing recipient during extruding.Thereby saved complicated pad EGR and discard separator, improved the reliability of press, reduced no extrusion cycle cycle time, and reduced equipment investment, reduced floor space.It is compared with background technology, has following characteristics:
1, the fundamental difference of tensioner ring formula fixation extrusion pad and normally used unitary fixed dummy block is that the tensioner ring and the remainder of fixed bolster are the assembly relations that separates fully.Tensioner ring do not have rigid constraint between its root and the connector, and the tensioner ring wall thickness is even in expansion process, cross section heat treatment performance unanimity, and stress and boundary condition can match with finite element analysis.The FEM of tensioner ring formula fixation extrusion pad analyzes the distortion cloud, as shown in Figure 2.
2, after the wearing and tearing of the tensioner ring in the tensioner ring formula fixation extrusion pad, only need change tensioner ring, reduce by 80%, easy installation and removal, not fragile pressure ram than changing whole dummy block cost.Simultaneously, on press, adopted a kind of special combustion gas self-lubricate technology that can not pollute goods, replaced people's hydrodynamic lubrication, guaranteed dummy block and pressed surplus separating automatically as supplementary means.
3, adopt a removable ring pad, both guaranteed the assembly relation of tensioner ring and connector, simple and practical, make and assemble easily, protected pressure ram to avoid the damage that the tensioner ring frequent deformation is brought again.
4, adopt tensioner ring formula fixation extrusion pad, the direct gain that this press is obtained is, the length of press master working cylinder, the stroke of main plunger have reduced 1/3, and non-extrusion cycle has reduced 15% circulation timei, cancel the pad circulatory system, reduced the weight and the cost of equipment thus significantly.Simultaneously, also benefit from good press performance and technological operation, be embodied in and install simply, easy to operate, production cycle is short; Multiple functional, flow process is simple and direct, and process route is short; Maintenance is easy, the attenuating expense, and downtime is short; Reduce investment cost, as reduced the occupation area of equipment and the melt pit degree of depth, simplified Equipment Foundations, reduced factory building height and width, reduced the driving span, plant working area and height space are fully used, reduce wearing and tearing and reduce spare part, transportation is installed and is saved time easily etc.Thereby, can corresponding reduction investment cost of equipment and working service cost.
