Abstract
The utility model relates to a combined machine barrel for plastic extruding machine and plastic injection machines. The bottom of an outer barrel is provided with a seamless steel tube with a flange ring, and an inner barrel is made by white iron. The inner barrel is arranged inside the outer barrel. The outer; the outer layer of the material intake is welded on para position of the reserved port on lower side of the outer barrel. The utility model has the advantage of scientific structure, high strength and wear resistance of the inner barrel and low cost. The service life of the utility model is 4 to 5 times the service life of current machine barrels. As the inner barrel and a screw rod are made of different materials and therefore have different expansion coefficients, therefore the locking phenomenon is prevented during operation.
Description
Technical field
The utility model belongs to plastic extruder injection machine machine barrel, particularly makes up the design and the manufacturing technology field of machine barrel.
Background technology
At present the plastic extruder injection machine machine barrel that generally uses is all for by 38 chromium manganese aluminium or 45
#The whole machine barrel that carbon junction steel is made.The material of supporting with it screw rod is identical with the material of machine barrel.Its weak point is that intensity is low, and the material of machine barrel and matching used screw rod with it is identical, and the coefficient of expansion is identical during running, and the two produces severe friction, and " locking " phenomenon takes place when serious, so average life is short, and cost is very high.
Summary of the invention
The purpose of this utility model is that a kind of combination machine barrel that is used for the plastic extruder injection machine is provided.
The utility model is achieved by the following technical solution:
The utility model is by 38 chromium manganese aluminium or 45 with existing
#The monoblock type extruder injection machine machine barrel that carbon junction steel is made makes the inner/outer tube made by two kinds of different metals into, is assembled into the combination machine barrel.Urceolus is made by seamless steel pipe, and its underpart has ring flange.Inner core is made by the very high white iron of hardness.Urceolus processing method processing routinely, white iron inner core need through hot investment casting and are polished down to require specification because of its hardness height.Inner core fits closely in the urceolus.But attire during assembling.
Using method of the present utility model is identical with existing using method, promptly with the supporting use of corresponding extruder injection machine.
The utility model has the advantages that, scientific structure, inner core intensity height, wear-resisting, different with the material of supporting screw rod, can " locking ", long service life during operation, can prolong 4～5 times with existing machine barrel than the life-span, price is low.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further specified.
Accompanying drawing and the utility model structural representation.
1-urceolus, 2-inner core, 3-feeding mouth, 4-ring flange.
The specific embodiment
Machine barrel is made up of seamless steel pipe urceolus 1 and white iron inner core 2.White iron inner core 2 closely is loaded in the seamless steel pipe urceolus 1 with ring flange 4.Feeding mouth 3 skins are seamless steel pipe, and internal layer is tightly adorned the spoken parts in traditional operas work durm, and feeding mouth 3 outer contrapositions are welded on the reserved opening of urceolus 1.
Claims (1)
