Embodiment Construction
[0014] The present invention will be further explained below in conjunction with the drawings and embodiments.
[0015] As attached figure 2 As shown, a small turning radius pipe bending machine forming mechanism for forming long steel pipes includes a pipe bending table 1, a clamping block 2 is installed on the right side of the pipe bending table 1, and a positioning plate 3 is installed on the pipe bending table 1. Wherein, a fixed-length baffle 4 is installed at the left end of the bending table 1, a core pulling cylinder 5 is installed on the right side of the bending table 1, and a core rod 6 is installed on the output shaft 501 of the core pulling cylinder 5.
[0016] Further, the core-pulling cylinder 5 can rotate around the bending axis of the pipe bending table 1. When the core-pulling cylinder 5 is in a horizontal position, the center of the core-pulling cylinder 5 coincides with the center axis of the positioning plate 3.
[0017] Furthermore, the fixed-length baffle 4 ...

A small turning radius pipe-bending machine forming mechanism for forming of a long steel pipe comprises a bend pipe platform (1). A clamping block (2) is arranged on the right side of the bend pipe platform (2), and a positioning plate (3) is arranged on the bend pipe platform (1). The small turning radium pipe-bending machine forming mechanism for forming of the long steel pipe is characterized in that a sizing baffle (4) is arranged at the left end of the bend pipe platform (1), a core pulling oil cylinder (5) is arranged on the right side of the bend pipe platform (1), and a core rod (6) is arranged on an output shaft (501) of the core pulling oil cylinder (5). According to the small turning radius pipe-bending machine forming mechanism for forming of the long steel pipe, a bend pipe bed body is used as a workpiece support body, the core rod of the pipe-bending machine and an oil cylinder which acts on the core rod are arranged on a bend pipe die core and rotates along with the die core, and the core rod of the pipe-bending machine and the core pulling oil cylinder are arranged on the bend pipe die core. Design is compact, a machine body is shortened by a half, the bend pipe bed body is used as the workpiece support body, the core rod of the pipe bending machine and the core pulling oil cylinder rotate along with a die core, and operation rotation radius is shortened. Compared with a traditional pipe-bending machine, the small turning radius pipe-bending machine forming mechanism has the advantages of being small in occupied area, safe in operation and the like, and meanwhile, the sizing baffle is additionally arranged on the rear portion of the pipe-bending machine, and sizing is convenient and fast.
Description
Technical field [0001] The invention relates to the technical field of mechanical forming equipment, in particular to a forming mechanism of a small turning radius pipe bending machine for forming long steel pipes that can reduce the floor space. Background technique [0002] Pipe bender is a kind of equipment that processes long steel pipe profiles into arc-shaped pipes. Pipe benders can be roughly divided into CNC pipe benders, hydraulic pipe benders and so on. Mainly used for electric power construction, highway and railway construction, boiler, bridge, ship, furniture, decoration and other aspects of pipeline laying and repairing. It has the advantages of multiple functions, reasonable structure and simple operation. [0003] Most of the existing pipe benders use hydraulic mechanisms and use molds for bending and forming. They are suitable for larger bending components. figure 1 As shown, when the traditional slender steel pipe is bent, one end of the long steel pipe is press-f...
