Description
Technical field
The utility model relates to bending machine, refers more particularly to special pipe bender of chain frame.
Background technology
Present special pipe bender of chain frame, when processing chair frame, because head is with respect to the interference of the installation dimension and the original structure of fuselage of fuselage, make that the chair frame can not disposable integral machine-shaping, and the chair frame need be divided into two parts usually respectively in the special pipe bender of chain frame bending, form the chair frame by welding then.So just make that the production efficiency of whole chair frame is lower, and the intensity of chair frame and presentation quality all have been subjected to considerable influence.
The utility model content
Technical problem to be solved in the utility model is: provide a kind of can be with the special pipe bender of chain frame of chair frame disposable integral machine-shaping.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: special pipe bender of chain frame, comprise: fuselage, one end of fuselage is provided with outrigger, outrigger is provided with head, be movably set with main shaft on the head, main shaft is provided with bending die, bend pipe arm and travelling gear, the bend pipe arm is provided with clamping cylinder and guide rail, the piston rod of clamping cylinder is provided with trip holder, and trip holder is movably arranged on the guide rail, and trip holder is provided with clamping die, described fuselage is provided with the main shaft oil cylinder, the piston rod of main shaft oil cylinder is provided with driving rack, driving rack and travelling gear engagement, and the back side of described outrigger is provided with vertically runs through outrigger, be used to dodge the groove of dodging of chair frame, adapt with it, described driving rack and main shaft oil cylinder are oblique layout.
The left end near fuselage is supported in the left side of described underbelly, adapts with it, and the back side of fuselage is provided with the hole of dodging that is used to dodge the chair frame on the right of dodging groove.
The beneficial effects of the utility model are: dodge groove owing to being provided with at the back side of outrigger, can dodge the chair frame after the bending well, thereby the machine-shaping of chair frame disposable integral can not needed chair frame segmentation bending is respectively formed the chair frame by welding manner then.By the chair frame that this bending machine forms, its overall appearance quality has obtained significantly improving, and, improved the intensity and the production efficiency of chair frame.In addition, because the deal of head section is heavier, therefore, by be positioned at the hole of dodging that the right of dodging groove is provided for dodging the chair frame at the fuselage back side, allow the left side support of underbelly can be arranged on the left end of fuselage, thereby guaranteed that whole bending machine is more firm.
