Abstract
The utility model relates to a pipe bender, which comprises a frame, a gearbox, a power wheel, an inner shaft, an outer shaft, a die, a press roll, and a swinging arm, wherein the inner shaft is connected with an inner shaft fixing sleeve through a connecting key; the inner shaft fixing sleeve is fixed on the gearbox; the outer shaft is sleeved on the inner shaft; the outer shaft is connected with the outer shaft fixing sleeve through the connecting key; an outer shaft fixing sleeve is fixed on the power wheel; the die is sleeved on the inner shaft and is fixed with the inner shaft through key connection; the lower end of the swinging arm is fixed with a positioning sleeve; the positioning sleeve is connected with the outer shaft through the connecting key; the upper end of the swinging arm is sleeved on the inner shaft through a bearing sleeve; an adjust handle and the press roll are arranged on the swinging arm; and the center of the press roll and the center of the die are in one identical horizontal surface. The pipe bender of the utility model changes the working mode that metal pipes are pulled to run by the friction force in the prior pipe bender, so that the phenomenon that the metal pipe is broken under the strain is avoided, the structure is simple, and the utility model can be used for bending metal pipes with thin pipe wall.
Description
Technical field
The utility model relates to a kind of bending machine.
Background technology
Existing bending machine operation principle is that metal tube is placed in the mould that links with line shaft, fixing by the pressure roller extruding, during work, line shaft drives mould and metal tube moves together, makes metal tube be bent into the bend pipe of required angle along mould, advances because metal tube is the frictionally pulling, therefore, this bending machine only is applicable to and bends the bigger metal tube of wall thickness, then will adopt servicing unit such as loose core for thin metal pipe, otherwise can break the thin metal tube of wall in the work.
Summary of the invention
The purpose of this utility model just provides a kind of simple in structure, can bend the bending machine of thin metal pipe.
Bending machine of the present utility model, comprise frame, gearbox, power wheel, interior axle, outer shaft, mould, pressure roller and swing arm, interior axle links to each other with interior axle fixed cover by connecting key, an interior axle fixed cover is fixed on the gearbox, outer shaft is on interior axle, be provided with copper sheathing up and down between outer shaft and the interior axle, outer shaft links to each other with the outer shaft fixed cover by connecting key, the outer shaft fixed cover is fixed on the power wheel, axle was gone up and is connected with interior axle fixing by key in mould was enclosed within, the lower end and the positioning sleeve of swing arm are fixed, positioning sleeve links to each other with outer shaft by connecting key, and on interior axle, swing arm is provided with regulating handle and pressure roller by bearing holder (housing, cover) in the upper end of swing arm, the center of pressure roller and mold center are on same horizontal plane, and regulating handle can make pressure roller move in the horizontal direction.
The operation principle of bending machine of the present utility model is: interior axle maintains static with mould, outer shaft in being enclosed within on the axle is driven by power wheel, and drive swing arm campaign, in the mould in the required metal tube that bends is placed on the axle, by regulating handle pressure roller is fixed metal tube, the motion of power wheel drives outer shaft, swing arm and pressure roller and moves together, and the motion of pressure roller makes metal be bent into required angle along mould.
Bending machine of the present utility model changes the working method of existing bending machine frictionally pulling metal tube motion, has avoided metal tube by the generation of tensile phenomenon, and it is simple in structure, the very thin metal tube of bendable tubulation wall.
