Abstract

The utility model provides a bending pipe device, comprising a bending pipe disk, and a forming pipe. The forming pipe is inserted from the tail end of a steel pipe required to be bent, the end part of the forming pipe is in a conical shape, and the end part of the forming pipe can withstand the bending position of the steel pipe. A scale disk is arranged on the bending pipe disk. The required bending angle of the steel pipe can be adjusted according to the scale disk. The bending pipe device provided by the utility model can ensure that the bending position of the steel pipe can not be deformed and the steel pipe has reliable quality, and the steel pipe can be bent into any angles. The bending pipe device has simple structure and convenient operation.

Description

Swan neck system

Technical field

The utility model relates to a kind of swan neck system.

Background technology

The swan neck system that uses is in the process of steel pipe bending at present, can make the circular arc portion flattening of steel pipe bending cause pipe deformation, simultaneously, also can cause part that steel pipe do not bend because stressed simultaneously and deviation or to the right left, thereby cause pipe deformation, more or less have the certain quality problem.

Summary of the invention

The utility model provides a kind of swan neck system, and its circular arc portion that can guarantee that steel pipe bends is not crushed and is out of shape, and the angle of steel pipe bending simultaneously can be regulated.

For reaching above-mentioned purpose, the utility model provides a kind of swan neck system, and it comprises a bend pipe dish, a setting pipe; Described setting pipe inserts from the tail end of the steel pipe of needs bending, and this setting tube end is tapered, and it can withstand the bending place of steel pipe.Described bend pipe dish is presented dial, can regulate the angle that steel pipe need bend according to this dial;

The utility model also comprises a positioning track, is arranged at bend pipe dish side, needs crooked steel pipe to be positioned in this positioning track, guarantees the bendability unanimity of each crooked in batches steel pipe;

The diameter of described setting pipe is suitable with the diameter of the steel pipe that needs bending;

The swan neck system that the utility model provides also comprises one handle, two grip blocks; This handle is arranged on the front end of steel pipe bending place, and is fixed by these two grip blocks.

The swan neck system that the utility model provides, its course of work is as described below:

The steel pipe of needs bending is put into track, be fixed and locate by positioning track, for guaranteeing that the steel pipe front end is in the process of stressed bending, its tail end can be because stressed and deviation left or to the right simultaneously, thereby the bendability unanimity that causes each crooked in batches steel pipe, and the angle of bend of steel pipe is guaranteed; Choose then and the adaptive setting pipe of this diameter of steel tube size kissing, be inserted in this steel pipe, the bending place that makes its tapered end withstand steel pipe can guarantee steel pipe like this in the process of bending, and the circular arc portion of its bending can not be crushed and cause this pipe deformation; Regulate the angle on the dial subsequently, make it consistent, hold handle with angle that steel pipe need bend, with this steel pipe along the required angle of bend pipe axle extension bending.

The swan neck system that the utility model provides, it can guarantee that the steel pipe bending place is indeformable, reliable in quality, and this steel pipe can bend arbitrarily angled, simple in structure, easy to operate.

Description of drawings

Fig. 1 is the structural representation of the swan neck system that provides of the utility model;

Fig. 2 is the structural representation of the setting pipe of the swan neck system that provides of the utility model.

The specific embodiment

Following according to Fig. 1 and Fig. 2, a kind of preferred forms of the present utility model is described.

As shown in Figure 1, the structural representation of the swan neck system 1 that provides for the utility model, it comprises 102 (as shown in Figure 2) of a bend pipe dish 101, one setting pipes.Described setting pipe 102 is inserted in the steel pipe 2 that needs bending, and its diameter matches with the diameter of the steel pipe 2 that needs bending, and these setting pipe 102 ends are tapered, and it can withstand the bending place of steel pipe.Described bend pipe dish 101 is rounded, and this bend pipe dish 101 is provided with dial 1012 (not illustrating among the figure); And a positioning track 103 is arranged, and be arranged at bend pipe dish side, need crooked steel pipe 2 to be positioned in this positioning track, guarantee the bendability unanimity of each crooked in batches steel pipe;

The swan neck system that the utility model provides also includes 104, two grip blocks of

handle

1041,1042; This handle 104 is arranged on the front end of steel pipe bending place, and is fixed by these two

grip blocks

1041,1042.

The steel pipe 2 of needs bendings is put into positioning track 103, is fixed and locatees, so just can guarantee steel pipe 2 front ends in the process of stressed bending, its tail end can be because the while is stressed deviation left or to the right, thereby cause its distortion; Choose the setting pipe 102 that matches with these steel pipe 2 diameter then, its tail end from this steel pipe 2 is inserted, can guarantee steel pipe 2 like this in the process of bending, the circular arc portion of its bending can not be crushed and cause this steel pipe 2 distortion; Can regulate the angle that steel pipe 2 needs bending according to the angle on the dial 1012, hold handle 104, this steel pipe 2 is bent required angle along bend pipe dish 101 extensions.

Claims

1. a swan neck system is characterised in that, it comprises a bend pipe dish, a setting pipe; Described setting pipe inserts from the tail end of the steel pipe of needs bending, and this setting tube end is tapered, and it can withstand the bending place of steel pipe; Described bend pipe dish is provided with can regulate the dial that steel pipe needs bending angle.
