Abstract
The utility model relates to the technical field of processing machinery, in particular to a protection type tube bending machine. The protection type tube bending machine comprises a machine frame, a machine bench, a compressing roller, a power wheel, a swinging arm and a blocking plate, wherein the machine bench is arranged on the machine frame, the compressing roller, the power wheel, the swinging arm and the blocking plate are all arranged on the machine bench, the power wheel and the blocking plate are respectively arranged at the two ends of the compressing roller, the power wheel is in rotary connection with the machine bench through the swinging arm, and a sheath, a guiding opening and a compressing rod are arranged on the machine bench. A tube to be processed is jacked into the horn-shaped guiding opening by the compressing rod, the sheath is inserted into the tube to be processed, bending process can be carried out by the compressing roller and the power wheel, and the tube to be processed is completely prevented from being in contact with external work pieces. The sheath is a metal corrugated tube of a sieve structure, the sheath can be bent along the tube and can protect the tube from being scratched and sinking for all the process, the bending flatness and the bending smoothness of the tube are guaranteed, and the quality of the tube is greatly improved. Furthermore, radial elastic shrinkage and expansion are achieved to meet the processing requirements of tubes in different diameters, and the adaptability is greatly improved.
Description
Technical field
The utility model relates to processing equipment technical field, especially a kind of protection type bending machine.
Background technology
The operation principle of existing bending machine is: metal tube is placed in the mould linking with line shaft, pressure roller extruding is fixing, during work, line shaft driven mold and metal tube move together, make metal tube along mould, be bent into the bend pipe of required angle, because metal tube is mainly to change by the position relationship between baffle plate, pressure roller and power wheel, carry out bending, in Forging Process, very easily scratch the outer wall of metal tube, even produce depression, affect the quality of metal tube.
Utility model content
In order to overcome existing bending machine, easily scratch pipe fitting outer wall, produce depression, affect the deficiency of pipe fitting quality, the utility model provides a kind of protection type bending machine.
The utility model solves the technical scheme that its technical problem adopts: a kind of protection type bending machine, comprise frame, board, pressure roller, power wheel, swing arm and baffle plate, board is arranged in frame, pressure roller, power wheel, swing arm and baffle plate are all arranged on board, power wheel and baffle plate lay respectively at the two ends of pressure roller, power wheel is rotatably connected with board by swing arm, and board is provided with sheath, targeting port and depression bar.
According to another embodiment of the present utility model, further comprise that sheath is the metal bellows of sieve structure.
According to another embodiment of the present utility model, further comprise in the crack of sheath between pressure roller and power wheel.
According to another embodiment of the present utility model, further comprise that targeting port is horn-like, is connected to the arrival end of sheath.
According to another embodiment of the present utility model, further comprise that depression bar is positioned at the front portion of targeting port.
The beneficial effects of the utility model are, sheath is set on board, targeting port and depression bar, processed pipe fitting is by the trumpet-shaped targeting port of depression bar jacking, insert sheath, under the effect of pressure roller and power wheel, carry out subsequently Bending Processing, do not contact with outside workpiece completely, sheath is the metal bellows of sieve structure, not only can be crooked with pipe fitting, whole process protection pipe fitting is not scratched and caves in, guarantee that pipe fitting bent flat lay the grain is sliding, greatly improve the quality of pipe fitting, and can do elastic shrinkage and expansion radially, to meet the processing needs of different-diameter pipe fitting, greatly improved applicability.
