Description
Technical field
The invention belongs to manage logical engineering and refrigerating pipe field, be specifically related to a kind of lead to part for extruded tube
Filled media and the processing technology of the logical part of pipe.
Background technology
The logical part of pipe is pipe fitting important in pipeline engineering, common are tee pipe fitting, four-way pipe fitting, U
Type pipe fitting etc..The logical part of pipe is of many uses in the logical engineering field of pipe, especially refrigeration, chemical industry, building and
The industries such as food are indispensable.
The production of the logical part of pipe can be by the process casting, forge, weld and extruding, wherein, casting,
The logical part of pipe that forging and welding obtain does not complys with the requirement of accurate pipe fitting, and extruded tube leads to part should at macrobending
Power district thing weld seam, shoulder presses thicken, and improve its intensity, and error is little, and therefore, extruded tube leads to part
Application in the preparation of prior art precision pipe fitting is more and more extensive.
Extruding is according to metal plastic deformation principle, utilizes the mould being contained on forcing press, sizable
Under extruding force effect, metal produces plastic deformation in die cavity, make blank become required form, size with
And there is the technical process of the part of certain performance.The technological approaches manufacturing the logical part of pipe is roughly divided into cold extrusion
Class big with hot extrusion two, wherein the cold extruding technique with low cost is with fastest developing speed.In the prior art, cold
Extrusion technique mainly has oiling extruding, water filling extruding, fills lead extruding and powder filling extruding etc..Wherein oiling or
Water filling extruding is all because of factor slower developments such as technical difficulty are big, equipment cost is high, extrusion length is undesirable.
And fill lead and extrude because of many favorable factors such as its extruded dimensional standard, low costs, cause in existing skill
Still to fill lead extruding in art.But lead is a heavy metal species, and human body and environment are had the biggest harm,
Must eliminate.In recent years the powder filling occurred extrudes new breakthrough to above-mentioned several fashion of extrusion, effective gram
Conventional art difficult point and environment drawback are taken.But owing to filling process is required strict by powder extruding, existing filling
The standby capacity efficiency of installing is low, and not yet develops efficient filling apparatus on market, constrains powder extruding skill
Art is promoted and large-scale production, it is impossible to meet the high-volume demand in market.
Filling lead extruding is to be injected in original pipe by the lead under molten state, puts into mould after cooling and carries out
Extruding.But lead is a heavy metal species, human and environment is caused the biggest harm, and fills lead processing step
Relatively more numerous and diverse, including sawing sheet, deburring, blow metal fillings, for the first time fill lead, the first dressing mouth of pipe,
Drill centers, perforate extruding, amputate cecum, polishing, for the first time deleading, annealing, second time fill lead,
Second time cleaning the mouth of pipe, swaging, otch, for the second time deleading, except lead, enlarging or reducing, polishing, acid
Property etc. 20 complicated work flows, wherein, after the lead owing to pouring into for the first time is squeezed, density
Increase, if directly swaging, easily rack tube wall, so that deleading, again fill lead and again move back
Lead, front and back needs to fill lead, twice deleading, twice cleaning mouth of pipe through twice, and technological process is complicated, effect
Rate is relatively low.
