The working procedure of the outer diameter correcting device when in working is simple, and the operation is convenient; the production efficiency is increased, and the production cost is reduced; with simple structure and firm clamping, the outer diameter correcting device cannot damage the steel pipe.
Description
Technical field
The utility model relates to a kind of means for correcting of steel pipe, especially a kind of means for correcting of outer diameter of steel pipes.
Background technology
Steel pipe is in process of production because operation factors such as drawing (or cold rolling) die wear, solution treatment distortion, aligning adjustment errors, can go out situations such as overproof overgauge of ready-made article external diameter or generation steel pipe ovality unavoidably, the steel pipe for light-wall pipe or high standard contract requires especially outstanding for external diameter especially.For random chi contract, in case the problems referred to above occur, general outer diameter of steel pipes bearing calibration is for welding tube head with argon arc welding earlier, so that the steel pipe tube head passes through the drawing-die seat, cold-drawn is corrected into the size of regulation.But, the bearing calibration of above-mentioned outer diameter of steel pipes will consume the length of steel pipe head 1.0～3.0cm, when steel pipe requires to the scale contract (steel pipe scale surplus is pressed standard generally in 0.3～1.0cm), the steel pipe that external diameter is above standard overgauge or ovality takes place is direct argon arc welding soldering tip just, steel pipe will be lacked chi after the soldering tip cold-drawn finishing, again the production that feeds intake again perhaps is judged to defective work; The loaded down with trivial details redundancy of operation when the means for correcting of existing steel pipe is worked, production efficiency is low, also increased the production cost of enterprise, in addition, the calibration equipment complexity of existing outer diameter of steel pipes,, take up room big, making and maintenance cost are higher, are easy to cause the steel pipe damage in the trimming process, have influenced the attractive in appearance and quality of steel pipe.
The utility model content
The purpose of this utility model is to provide a kind of means for correcting of outer diameter of steel pipes.Operation is simple, easy to operate during the utility model work, has not only improved production efficiency, has also reduced production cost; The utility model is simple in structure, and clamping firmly and not can damage steel pipe.
The utility model is achieved in that a kind of means for correcting of outer diameter of steel pipes, constitutes to comprise and also include the drawing bar by drawbench, and drawing bar one end offers screw thread, and the end of thread of drawing bar is provided with the nut of threaded engagement from left to right and clamps special purpose parts.
In the means for correcting of above-mentioned outer diameter of steel pipes, also be provided with nylon jacket on the drawing bar.
The means for correcting of aforesaid outer diameter of steel pipes is provided with a nylon jacket every 1.5～2.0mm on the drawing bar.
The beneficial effects of the utility model: compared with prior art, the utlity model has following advantage:
Operation was simple, easy to operate when 1), the utility model was worked.The bearing calibration of existing outer diameter of steel pipes need be welded tube head with argon arc welding, then cold-drawn or be rolled into the size of standard; When steel pipe requires the scale contract, also need to increase operations such as feed supplement processing, loaded down with trivial details redundancy; And in the utility model when work, only need steel pipe is inserted in the drawing bar, and the dolly clamp drawing bar of drawbench carries out drawing to be proofreaied and correct and get final product, and operation is simple, easy to operate.
2), the utility model has improved production efficiency.Because operation is simple, easy to operate during the utility model work, so the utility model has improved production efficiency greatly; Through applicant's test, operating efficiency of the present utility model can improve 4～6 times than the bearing calibration of existing outer diameter of steel pipes.
3), the utility model has reduced production cost.It is to weld tube head with argon arc welding that existing outer diameter of steel pipes bearing calibration has a procedure, and becoming in the product process needs to use a large amount of argon arc welding auxiliary materials, and producing cost is higher, and does not need the argon arc welding soldering tip during the utility model work, has reduced production cost; Simultaneously, operation the utility model of existing loaded down with trivial details redundancy is simplified a procedure, has saved equipment and investment in human resources in the production process, has reduced cost of investment; Therefore, the utility model has reduced production cost widely, has obtained tangible economic benefit.
4), the utility model is simple in structure, clamping firmly and not can damage steel pipe.The utility model only increases the drawing bar and clamps special purpose parts on the basis of existing drawbench, simple in structure, making and maintenance cost are lower; The utility model when work, drawbench dolly pincers drawing bar, the drawing bar promotes steel pipe and carries out drawing and proofread and correct by clamping special purpose parts, the device clamping firmly, stability and safety during work; The utility model is except not direct clamping steel pipe, and also the drawing bar is provided with nylon jacket, makes steel pipe can not damage steel pipe in the external diameter trimming process, has guaranteed the attractive in appearance and quality of steel pipe.
