Abstract
The utility model discloses an inner groovy cold drawing dysmorphism tubular product, including special -shaped tubular product body, the outer loop diameter of dysmorphism tubular product body is 17cm, the wall thickness of dysmorphism tubular product body is 2cm. The inboard of dysmorphism tubular product body is equipped with the rectangle recess, the groove depth s of rectangle recess is 2mm, the groove width d of rectangle recess is 3mm. Dysmorphism tubular product body is stainless steel. The utility model discloses an inner groovy is just made on the inner wall at tubular product at the in -process of cold drawing tubulation to the improvement of flower section mould utensil, has avoided the process of secondary operation system shape after the tubular product shaping, and process time is short, and is efficient.
Description
Technical field
The utility model relates to the technical field of stainless steel pipe processing, more particularly, relates to a kind of special stainless steel tubing with inner groovy.
Background technology
Stainless steel pipe processing is mainly cold-drawing technology, and cold-drawn is a kind of processing technology of material, and for metal material, cold-drawn refers to reach certain shape and certain mechanical property, and carries out drawing be in the condition of normal temperature at material under.The product of cold-drawn compares to thermoforming to be had: the advantage that dimensional accuracy is high and surface smoothness is good.The stainless steel cold-drawn tubing of main flow is the circular pipe of cylindrical inner circle on the market now, only there are differences on external diameter, internal diameter and wall thickness.The convenient lock used under the particular surroundings such as train, aircraft is at present all the lock core using inner core abnormity, just can open easily with the use of the key identical with special-shaped inner core.The lock core of such inner core abnormity is all generally processing annulus, at the enterprising line cutting of the inner ring of annulus or other cutting techniques, makes flower pattern, such process not only cumbersome, and inefficiency.The inwall of my corporation plan when cold-drawn tubulation just at drawn tube designs inner groovy simultaneously for this reason, and after such tubing is made, directly cutting burst just can employ.
Summary of the invention
Goal of the invention: for the deficiencies in the prior art, applicant is through repeatedly putting into practice improvement, and devise a kind of inner groovy cold-drawn heterotype tubing, the inner ring when cold-drawn tubulation just at tubing makes inner groovy, like this after tubing is made, directly cutting burst can use.
Technical scheme: in order to realize foregoing invention object, the technical scheme that the utility model adopts is: a kind of inner groovy cold-drawn heterotype tubing, comprise heterotype tubing body, the outer annular diameter of described heterotype tubing body is 17cm, and the wall thickness of described heterotype tubing body is 2cm.The inner side of described heterotype tubing body is provided with rectangular recess, and the groove depth s of described rectangular recess is 2mm, and the groove width d of described rectangular recess is 3mm.
Described heterotype tubing body is stainless steel.
Beneficial effect: compared with prior art, its beneficial effect is the utility model:
1, the utility model is by the improvement of flower pattern mould, and in the process of cold-drawn tubulation, just on the inwall of tubing, make inner groovy, avoid the operation of secondary operations shape after tube forming, process time is short, and efficiency is high.
Accompanying drawing explanation
Fig. 1 is the schematic cross-section of a kind of inner groovy cold-drawn of the utility model heterotype tubing.
Detailed description of the invention
Below by a most preferred embodiment, the technical program is described in detail, but protection domain of the present utility model is not limited to described embodiment.
As shown in Figure 1, a kind of inner groovy cold-drawn heterotype tubing, comprises heterotype tubing body 1, and the outer annular diameter of described heterotype tubing body 1 is 17cm, and the wall thickness of described heterotype tubing body 1 is 2cm.The inner side of described heterotype tubing body 1 is provided with rectangular recess 2, and the groove depth s of described rectangular recess 2 is 2mm, and the groove width d of described rectangular recess 2 is 3mm.
Described heterotype tubing body 1 is stainless steel.
The above is only preferred embodiment of the present utility model; be noted that for those skilled in the art; under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
Claims (2)
