Abstract
The utility model discloses an elbow pipe bending device which comprises an operating table, a bending die, a combined inner core and a combination oil cylinder hinged to the operating table. The combined inner core used for forming of pipe fittings comprises a forming inner core and a supporting inner core. The combination oil cylinder pushes the supporting inner core to enter a pipe fitting to fix the forming inner core during pipe bending, and withdraws the supporting inner core from the pipe fitting after pipe bending is completed. The elbow pipe bending device is simple in operation, safe and reliable, labor intensity is relieved for workers, and product quality and operating efficiency are improved.
Description
Technical field
The utility model relates to a kind of angle pipe equipment.
Background technology
Existing little elbow radius elbow product all is through manually inner core being put into pipe fitting inside; Use common hydraulic test bent into shape, because in the forming process, mutual extrusion between tube wall and inner core; After causing machining; Inner core closely contacts with tube wall, relies on artificial taking-up labour intensity very big, and easily product is damaged.
Summary of the invention
The utility model problem to be solved just provides a kind of bend pipe bending press, and is simple to operate, safe and reliable, reduces working strength of workers, improves the quality of products and operating efficiency.
For solving the problems of the technologies described above; The utility model adopts following technical scheme: a kind of bend pipe bending press; The combination inner core that comprises workbench, bending die and be used for formation of tubes; Said combination inner core comprises the moulding inner core and supports inner core; Said bend pipe bending press also comprises the composite oil cylinder that is hinged on the said workbench, and composite oil cylinder described in the bend pipe process promotes to support inner core and gets into the fixing said moulding inner core of pipe fitting, and said composite oil cylinder detached pipe fitting with said support inner core after bend pipe was accomplished.
Further; Said composite oil cylinder comprises master cylinder and secondary cylinder; Said support inner core is provided with stepped hole; Said secondary cylinder piston is installed in the said stepped hole, and master cylinder piston promotes to support inner core and gets into the fixing said moulding inner core of pipe fitting in the bend pipe process, and secondary cylinder piston detached pipe fitting with said support inner core after bend pipe was accomplished.
Further, said support inner core end is provided with the breach of the said moulding inner core of chucking.
Further, said moulding inner core one end is provided with the moulding curved surface, and the other end is provided with the projection that behind formation of tubes, offsets with pipe fitting inner wall.
The beneficial effect of the utility model: the utility model utilizes composite oil cylinder to replace the existing manual operation; Adding only needs pipe fitting is placed on the workbench man-hour; To support inner core by composite oil cylinder pushes in the pipe fitting; Treat that will support inner core by composite oil cylinder again after bend pipe is accomplished pulls out, effectively reduce working strength of workers, improved production efficiency of products and quality.
Description of drawings
Below in conjunction with accompanying drawing the utility model is done further explanation:
Fig. 1 is the structural representation before the utility model work;
Fig. 2 is the structural representation in the utility model work;
Fig. 3 is the structural representation after the utility model work.
The specific embodiment
With reference to Fig. 1, a kind of bend pipe bending press comprises workbench 1, bending die 2 and the combination inner core that is used for formation of tubes; The combination inner core comprises moulding inner core 5 and supports inner core 4; Existing method of operating, manual with moulding inner core 5 with support inner core 4 and put into and treat that middle part that crooked pipe fitting, moulding inner core 5 are positioned at pipe fitting is used for the moulding of bend pipe cambered surface; Support inner core 4 and be positioned at the pipe fitting two ends; Can prevent to be out of shape when pipe fitting is crooked, the utility model adopts composite oil cylinder to replace manual operations, each hinged composite oil cylinder 3 at the two ends of workbench 1; Composite oil cylinder 3 promotes to support inner core 4 and gets into fixedly moulding inner core 5 of pipe fitting in the bend pipe process, and composite oil cylinder 3 will support inner core 4 and detach pipe fitting after bend pipe is accomplished.
Support the breach 41 that inner core 4 ends are provided with the said moulding inner core 5 of chucking, be convenient to moulding inner core 5 is positioned, improve the formation of tubes quality.
Moulding inner core 5 one ends are provided with moulding curved surface 52, and the other end is provided with the projection 52 that behind formation of tubes, offsets with pipe fitting inner wall.So just guarantee moulding inner core 5 after the pipe fitting bending, can be not fully and tube wall be adjacent to, make things convenient for moulding inner core 5 to take out.
Operation principle:
With reference to Fig. 1, before the work, pipe fitting is put workbench 1, in pipe fitting, put into moulding inner core 5;
With reference to Fig. 2, during work, the master cylinder piston 31 of composite oil cylinder 3 promotes to support inner core 4 and gets into pipe fitting, and makes support inner core 4 chucking moulding inner cores 5; Bending die 2 is descending, drives composite oil cylinder 3 in the time of the pipe fitting distortion and rotates, and when being depressed into the required angle of product, horizontal reset on the bending die 2, the secondary cylinder piston 32 of composite oil cylinder 3 are drawn back and supported inner core 4, and composite oil cylinder 3 automatically resets under the gravity effect;
With reference to Fig. 3, after the work, take out the moulding inner core 5 in the bend pipe, treat processing next time.
Through the foregoing description, the purpose of the utility model is by in full force and effect having reached.The personage who is familiar with this skill should be understood that the utility model includes but not limited to the content of describing in the accompanying drawing and the top specific embodiment.Anyly do not depart from the function of the utility model and the modification of structural principle all will be included in the scope of claims.
