Abstract
An elbow cold forming machine comprises a hydraulic pressure station (1), a pair of hydraulic cylinders (2), a pair of elbow bases (3) and an arc-shaped stopping block (4), wherein oil outlets of the hydraulic pressure station (1) are communicated with oil inlets of the hydraulic cylinders (2) through oil pipes, the elbow bases (3) are installed at one ends of pistons ends of the hydraulic cylinders (2), and the arc-shaped stopping block (4) is located in the front of the elbow bases (3). The machine has the advantages that pressure is exerted on two ends of a round pipe through a double hydraulic cylinder mode, the round pipe is in contact with the arc-shaped stopping block, the bending effect is achieved, the heating process is omitted and the time and the labor are saved.
Description
Technical field
The utility model relates to the sheet metal manufacture field, relates in particular to a kind of bend pipe cold-forming machine.
Background technology
At present, existing bend pipe is when carrying out bending machining, all be to adopt the mode of heating to make steel plate generation thermo-elasto-plasticity be out of shape to obtain our required shape, its weak point is that the heating-up temperature of aforesaid way has strict requirement, if over-heating or do not reach the heating standard, all can not reach required bending effect, and heating needs power consumption.
Summary of the invention
The purpose of this utility model is exactly for existing bend pipe when carrying out bending machining, all be to adopt the mode of heating to make steel plate generation thermo-elasto-plasticity be out of shape to obtain our required shape, heating-up temperature has strict requirement, if over-heating or do not reach the heating standard, all can not reach the deficiency of required curved shape, and a kind of bend pipe cold-forming machine is provided.
The utility model is comprised of Hydraulic Station, a pair of hydraulic jack, a pair of bend pipe base and block arc, Hydraulic Station oil-out communicate with the oil-in of hydraulic jack by oil pipe, the bend pipe floor installation is at piston rod one end of hydraulic cylinder, and block arc is positioned at bend pipe base the place ahead.
The utility model has the advantages that: this device adopts the mode of Double-hydraulic-cylinder to be exerted pressure in the pipe two ends, and meanwhile pipe contacts with block arc, has namely reached flecition, saves heating process, and is time saving and energy saving.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
As shown in Figure 1, the utility model is comprised of Hydraulic Station 1, a pair of hydraulic jack 2, a pair of bend pipe base 3 and block arc 4, Hydraulic Station 1 oil-out communicate by the oil-in of oil pipe with hydraulic jack 2, bend pipe base 3 is installed in piston rod one end of hydraulic cylinder 2, and block arc 4 is positioned at bend pipe base 3 the place aheads.
Occupation mode: during use, first the pipe two ends are placed on respectively on a pair of bend pipe base 3, by operation Hydraulic Station 1, make a pair of hydraulic jack 2 collaborative works, pipe is pushed on the block arc 4, and pipe is carried out bending operation.
