Description
Technical field
The utility model relates to aluminium section bar manufacturing technology field, particularly relates to a kind of pressurizing unit comprising extrusion axis and supporting recipient.
Background technology
The production procedure of aluminium section bar mainly comprises founding, extruding and surface treatment three processes.The process of extruding needs pressurizing unit to carry out usually.The recipient that pressurizing unit generally comprises extrusion axis and matches with extrusion axis, conventional extrusion axis and the design of supporting recipient are all straight-bar straight barrel types.Wherein, as shown in Figure 1, described extrusion axis comprises the base 1, middle seat 2, changeover portion 3 and the pressure ram 4 that are fixedly connected sequentially to the structure of extrusion axis, and wherein changeover portion 3 is knuckle, and its axial length is much smaller than the axial length of pressure ram.Although this knuckle partly can solve the problem that stress in process is concentrated, that can not effectively decompose in the extrusion axis course of work is lateral stressed.Because first extrusion axis is that pressure ram front end is stressed in the course of the work, this knuckle is the weakest maximum moment stress point, causes extrusion axis and very easily ruptures in this place, cause damp production, cost increase.Particularly for small extruding machine, its pressure ram is slender rod piece, and off-axis has become the extruding production problem that must solve.
And the recipient of the coaxial design matched, shown in Figure 2, comprise changeover portion cavity 5 and pressure ram cavity 6, its changeover portion cavity 6 is also knuckle, and its axial length is much smaller than the axial length of depression bar cavity.In aluminium section bar production extrusion process, in order to avoid extrusion axis ruptures because of lateral stressed, movable dummy block is mostly adopted to extrude.The axial distance that dummy block is encased inside knuckle is very little, being easy to break away, causing danger when extruding.Because dummy block diameter is slightly less than recipient diameter, only have minimum gap between the two, only have 0.15--0.5mm to the extruding of high-precision section bar, this directly threatens safety when being encased inside nozzle.
Authorized announcement date is 2010.12.22, Authorization Notice No. is CN201676911U, disclose a kind of section aluminum extrusion shaft integration structure, it comprises extrusion axis and dummy block, described extrusion axis one end is link, and dummy block one end and above-mentioned extrusion axis link fix as one, and extrusion axis is identical with the binding end external diameter of dummy block, dummy block increases from binding end gradually to other end external diameter, and dummy block outer face is concave spherical.It focuses in the integral structure of extrusion axis and dummy block and the structure of dummy block.
Shen Qing Publication day is 2012.12.19, application publication number is CN102825089A, discloses a kind of extrusion axis, and it comprises the working end that one end has protruding supportive body and is connected with the described supportive body other end, wherein, the material of described working end is 4Cr5MoSiV1.It focuses in the material of extrusion axis working end.
Although these two disclosed patents have tapered section (this is the conventional design layout of big-and-middle-sized ectrusion press extrusion axis) at stiff end, but because of straight bar section and changeover portion diameter difference too large (namely tapering is too large), this changeover portion remains the weak spot of extrusion axis, off-axis occurs still herein.In addition, the supporting recipient of these two patents is still straight tube, and cannot solve safety problem when being encased inside nozzle, taper transitions section is in outside recipient in the whole course of work.CN201676911U patent protection point is to use fixation extrusion pad.CN102825089A patent protection point is: the end of causing because of Material Selection in order to avoid extrusion axis is damaged, and has selected high performance material to make extrusion axis end.These two patents do not relate in extrusion process because of extrusion axis lateral stressed time extrusion axis fracture problem, the technical problem that is related to is completely different.Do not solve safety problem when extruding is encased inside tin simultaneously yet.
