Description
Technical field
The present invention relates to a kind of silkworm cocooning heating extruded type forming method of wear-resisting type silkworm frame.
Background technology
Extrusion molding is also called extrusion molding in plastic processing, using hydraulic press pressure in mould in nonrubber extrusion machining
The extrusion of tool itself claims to extrude.Refer to material by the effect between extruder barrel and screw rod, thermoplastification is received on side, while by screw rod to
Preceding push, continues through head and is made a kind of processing method of various cross section articles or semi-products.The principle of extrusion molding is such as
Under：Raw material enters feeding cylinder from hopper, under screw rod turning effort, is acted on forward by material tube inner wall and screw surface fricting shearing
Feeding section is transported to, is fed forward in this bulk solids while being compacted；In compression section, spiral groove depth shoals, further compacting,
Acted on material tube inner wall fricting shearing in barrel external heat and screw rod simultaneously, material temperature is raised and starts melting, and compression section is terminated；Homogenizing
Section makes material uniform, constant temperature, quantitative, level pressure melt extrusion, to head aftershaping, product is obtained through sizing.
With expanding economy, the development of modern silkworm industry is more and more extensive.Silkworm frame has important work during sericulture
With the processing method of silkworm frame is varied in the prior art.Extrusion molding is the method for wherein commonplace processing, but existing
Some silkworm frames are in extrusion molding processing, and the defect rate of silkworm frame is higher.And the output of plastic extruder is low, is not easy to industry
The production of change.
The content of the invention
A kind of silkworm cocooning wear-resisting type silkworm frame is provided present invention aim at for the deficiency existing for prior art
Heating extruded type forming method technical scheme, by the design of multistation plastic extruder, can disposably realize multiple
The processing of product, effectively increases output, industrialized production of being more convenient for, simple structure, the production automation.
In order to solve the above-mentioned technical problem, present invention employs a kind of silkworm cocooning heating extruded type of wear-resisting type silkworm frame
Forming method, it is characterised in that：Comprise the following steps：
