Abstract
The utility model relates to a three-head spindle for producing a thin-wall bent pipe. The three-head spindle consists of a front connecting piece, a middle connecting piece, a rear connecting piece, ball heads and safety pins. The three-head spindle is characterized in that the front connecting piece is an integral body, a ball head is embedded into one side of the front connecting piece, one side of the middle connecting piece is open, a ball head is embedded into the other side of the middle connecting piece, one side of the rear connecting piece is open, the ball heads are fixed through the safety pins, the ball head of the front connecting piece is connected with the middle connecting piece and the ball head of the middle connecting piece is connected into the rear connecting piece. The three-head spindle has the advantages that the structure is simple, the thin-wall bent pipe with thickness being a 1.0mm can be produced, the utilization ratio of product materials is improved and 20 percent of materials can be saved. By adopting the three-head spindle, the internal supporting area of a pipe wall in a bent pipe area is increased; and by adopting a boost-type pipe bending machine, the bent pipe area is prevented from being fractured.
Description
Technical field
The utility model relates to a kind of three axles of producing thin-winding pipe, is used for the processing of automobile exhaust system tubulation.
Background technology
Bent tube technique is widely used in machinery manufacturing industry, and tube wall is between 1.2mm-1.5mm.1.2-1.5mm the tube material cost is big.The area that plain mandrel extend into the bend pipe deformed region is little, can not cover whole bend pipe zone, often fold takes place and subside during bend pipe, is easy to generate quality problems.
Summary of the invention
The purpose of the utility model is to provide a kind of three axles of producing thin-winding pipe, adopts three axles, increases bend pipe zone tube wall inner support area; And adopt the assisted bending machine, prevent to rupture in the bend pipe zone.
The technical scheme of the utility model is such realization: produce three axles of thin-winding pipe, and by anterior connector, middle part connector, rear portion connector; Bulb Xiao not formed, and it is characterized in that: anterior connector is an integral body; Anterior connector one side embeds bulb, and connector one side opening opposite side in middle part embeds bulb, rear portion connector one side opening; Bulb is not through fixing, and the bulb of anterior connector links to each other with the middle part connector, and the bulb of middle part connector is connected in the connector of rear portion.
The good effect of the utility model is that it is simple in structure, and it is simple in structure, can produce the 1.0mm thin-winding pipe, has improved the product material utilization rate, saves material 20%.
Description of drawings
Fig. 1 is the structure chart of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is done further description: produce three axles of thin-winding pipe, by anterior connector 1, middle part connector 2; Rear portion connector 3, bulb 4 is not sold 5 and is formed; It is characterized in that: anterior connector 1 is an integral body, and anterior connector 1 one sides embed bulb 4, and connector 2 one side opening opposite sides in middle part embed bulb 4; Rear portion connector 3 one side openings; Bulb 4 is not fixed through selling 5, and the bulb of anterior connector links to each other with the middle part connector, and the bulb of middle part connector is connected in the connector of rear portion.
Operation principle, bending machine are carried out bend pipe when work, if in pipe, do not support, when bend pipe, can subside during bend pipe, and we put into pipe with bulb in order to prevent to subside, and for three axles of light-wall pipe bulb employing, extend into pipe fitting bend pipe deformed region
,Be close to pipe fitting inner wall and reduce stretcher strain.
Bulb inserts in the pipe, and extend into center of turntable, and fixture block clamps pipe fitting with rotating disk and also drives the pipe fitting bending, and bulb is close to pipe fitting inside, prevents that pipe fitting from subsiding and reduce bend pipe and be out of shape fold.Three axles are bigger than the pipe fitting of conventional mandrel contact before area, and three core prints connect through bulb, and certain bending can take place, and can rotate with the variation of bend pipe angle.
Claims (1)
