Abstract

The utility model discloses a pipe bending device of utilizing a three-roller plate bending machine, which comprises three roller dies. The outer circumferential surface of each roller die is an arc groove, the three roller dies are respectively and fixedly installed on three rollers, and grooves of the three roller dies are mutually arranged opposite. As installation is convenient, a lower roller die is usually manufactured into a symmetric subdivision roller die, and the symmetric subdivision roller die is installed on a lower roller through spot welding. The pipe bending device enables a bent pipe to uniformly deform in the deformation process, enhances the qualified ratio of products and lowers the labor intensity compared with the traditional manual pipe bending.

Description

A kind of swan neck system that utilizes three rolls plate bending machine

Technical field

The utility model relates to a kind of bend pipe servicing unit.

Background technology

In some mechanical processing industries, usually metal tube is bent into required shape, to be fit to various needs.It is at first to fill quartz sand in pipe that general traditional bend pipe is made, in crooked position heating, brake forming on some columniform outer circumference surfaces then; Rely on such cylindrical device to make bend pipe, labour intensity is big, and efficient is low, and the size at tube bending position is wayward during making, occurs waste product easily.

Summary of the invention

In order to overcome the weak point that prior art exists, the utility model aims to provide the bend pipe processing unit (plant) that a kind of labour intensity is low, production efficiency is high, percent defective is low.

The technical solution of the utility model: on three rollers of prior art three rolls plate bending machine, fixedly install the roller die that outer circumference surface is a circular groove respectively, promptly go up two following roller dies of roller die for one, the groove of three roller dies over against.

Roller die is pretty troublesome down owing to assembling on two lower rolls of three rolls plate bending machine is described, so roller die generally is processed into symmetrical subdivision roller die down.

After adopting said apparatus, the bend pipe process is to realize under the slow extruding of roller die, because the surface of groove is an arc, pipe is the size even variation in deformation process, the yield rate height, and labour intensity reduces

Description of drawings

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the cutaway view of roller die;

In the accompanying drawing: 1-roller die 2-following roller die 3-treat bend pipe gone up.

The specific embodiment

The utility model is described in further detail below in conjunction with the drawings and specific embodiments.

As shown in Figure 1, the size of roller die groove is definite according to treating the bend pipe diameter, and to guarantee to reduce the variation of caliber in the process of bending, the interior hole dimension of roller die guarantees to install on the corresponding up-down rollers.It is big that whole roller die 2 down is installed on the roller difficulty, usually lower roll is molded as symmetrical subdivision roller die, by spot welding two symmetrical subdivision roller dies is combined into one during installation and is fixed on the lower roll; Last roller die 1 does not need subdivision, can be by the top roll top roll of fixedly packing into of touching the pillow; The groove of three roller dies mutually over against.

In bending the pipe process, at first rise the veneer reeling machine top roll, treating that bend pipe is positioned over down in the groove of roller die, going up roller die then presses down, last roller die groove is treated that bend pipe applies certain pressure, treat bend pipe 3 this moment simultaneously by the groove of three roller dies, restart twice roller die 2 rotations and drive 1 rotation of top roll mould, treat that bend pipe 3 bends to required shape thereby make.Easily crack because the deformation quantity of pipe is excessive, thus for the big pipe of amount of bow preferably by dividing deformation to realize several times.The utility model is applicable to that caliber is less than 57 millimeters pipe.

Claims (2)

1. a swan neck system that utilizes three rolls plate bending machine comprises three rollers, it is characterized in that: on three rollers, fixedly install the roller die that outer circumference surface is a circular groove respectively, the groove of three roller dies over against.
2. the swan neck system that utilizes three rolls plate bending machine according to claim 1 is characterized in that: following roller die (2) is made up of two symmetrical subdivision roller dies.
