Abstract
The utility model relates to an alloy steel composite steel tube used as machine cylinder, comprising a special alloy steel tube and a common steel tube. The special alloy steel tube and the common steel tube are mutually nested into one. The special alloy steel tube is a 38CYMOALA alloy steel tube. Compared with the prior special alloy steel tube used as machine cylinder, the utility model has the advantages of reduced alloy steel consumption, reduced cost and improved economical efficiency.
Description
(1) technical field
The utility model relates to a kind of rubber and plastics machine field, especially a kind of alloyed steel composite steel tube.
(2) background technique
For rubber and plastics machine equipment, the barrel of machine barrel all needs to make with wear-resisting material, the general Special Alloy Steel that adopts through nitriding treatment, barrel rubbing surface after using the regular hour has wearing and tearing, barrel can not continue to use, if barrel all adopts alloy steel material to make, because the cost of alloyed steel is higher, the cost of whole machine barrel is higher, and the utilization ratio of material is low.
(3) summary of the invention
In order to overcome the deficiency that alloyed steel tube material utilization ratio is low, cost is high that is used for machine barrel in the prior art, the utility model provides a kind of stock utilization height, the alloyed steel composite steel tube that is used for machine barrel that cost is very low.
The technological scheme that its technical problem that solves the utility model adopts is:
A kind of alloyed steel composite steel tube that is used for machine barrel comprises the special metals steel pipe, also comprises common steel tube, and described special metals steel pipe is integral with described common steel tube is mutually nested.
Further, described special metals steel pipe is a 38CYMOALA alloyed steel steel pipe, and the alloyed steel through nitriding treatment has good wear resistance.
Further, described special metals steel pipe is distributed in internal layer, and described common steel tube is distributed in skin, and as the barrel of machine barrel, its rubbing surface is at internal layer.
The beneficial effect of alloyed steel composite steel tube described in the utility model mainly shows: the alloyed steel steel pipe that machine barrel uses in the relative prior art, composite steel tube described in the utility model, 38CYMOALA alloyed steel steel pipe is mutually nested with common steel tube to be integral, the tube fraction face still adopts the special metals steel, another side then adopts common steel tube, and the cooperation between two steel pipes adopts the method for shrinkage just can realize, can reduce the consumption of alloyed steel, reduce cost, improved Economy.
(4) description of drawings
Fig. 1 is the sectional view that is used for the alloyed steel composite steel tube of machine barrel of the present utility model.
(5) embodiment
Below in conjunction with accompanying drawing the utility model is further described.
With reference to Fig. 1, a kind of alloyed steel composite steel tube that is used for machine barrel, comprise special metals steel pipe 1, common steel tube 2, described special metals steel pipe 1 is a 38CYMOALA type alloyed steel steel pipe, mutually nested being integral of method that special metals steel pipe 1 and common steel tube 2 adopts shrinkages.When using as barrel, internal layer is a 38CYMOALA alloy steel pipe 1, has good wear resistance, and skin is 20
#Steel pipe 2.Can reduce the consumption of alloyed steel, reduce cost.
Claims (3)
1, a kind of alloyed steel composite steel tube that is used for machine barrel comprises the special metals steel pipe, it is characterized in that: also comprise common steel tube, described special metals steel pipe is integral with described common steel tube is mutually nested.
2, a kind of alloyed steel composite steel tube that is used for machine barrel as claimed in claim 1, it is characterized in that: described special metals steel pipe is a 38CYMOALA alloyed steel steel pipe.
3, a kind of alloyed steel composite steel tube that is used for machine barrel as claimed in claim 2, it is characterized in that: described alloy steel pipe is distributed in internal layer, and described common steel tube is distributed in skin.
