A steel pipe bending machine and its forming process

Abstract

The invention discloses a steel pipe bending machine. The steel pipe bending machine comprises a base on which a cylinder is arranged; a gear which engages with a rack is arranged at the end part of the cylinder; the rack is fixedly arranged on a baffle on the base; a motor is arranged on the base; a transmission gear set is arranged at the lower end of the motor; a cushion block is arranged at the lower end of the transmission gear set; a pneumatic control switch is arranged at the lower part of the cushion block; a workbench is arranged at the front end part of the base; a lifting cylinder is arranged at the lower end of the workbench; a steel pipe bending die set is arranged on the workbench; the head part of the lifting cylinder passes through a through hole in the workbench and then is propped against the bottom part of a steel pipe bending die set; the steel pipe bending die set is of a concave-convex alternated shape. The invention also discloses a forming process of the steel pipe bending machine. With the adoption of the steel pipe bending machine and the forming process therefore, a steel pipe can be bent and formed at a time, and the situation that single surface of the bent steel pipe is incompletely processed can be avoided; in addition, the bent pipe has a smooth and clear circular arc, and the deformation of the steel pipe is reduced.

Description

technical field [0001] The invention relates to a steel pipe bending machine and a forming process thereof. Background technique [0002] The steel pipe bending machine is used for bending stainless steel and other non-ferrous metal thin-walled garden pipes, square pipes, and rectangular pipes. Bend it into any arc as needed. When using this machine to bend pipes, steel pipes of different shapes can be cold-formed according to different needs. [0003] However, due to the defects in the design of the steel pipe bending module of the current steel pipe bending machine, the steel pipe cannot be bent and formed at one time, and secondary and three processing are required, which wastes time and reduces production efficiency; secondly, the steel pipe When the bending module bends the pipe, the support wheels provided in the groove of the steel pipe bending module do not rotate at the same time, causing the steel pipe to slide in the groove of the steel pipe bending module, and ...

[0003] However, due to the defects in the design of the steel pipe bending module of the current steel pipe bending machine, the steel pipe cannot be bent and formed at one time, and secondary and three processing are required, which wastes time and reduces production efficiency; secondly, the steel pipe When the bending module bends the pipe, the support wheels provided in the groove of the steel pipe bending module do not rotate at the same time, causing the steel pipe to slide in the groove of the steel pipe bending module, and finally the bending steel pipe produces a single-sided processing error. The consequences of perfection; finally, the unreasonable forming process of the steel pipe bending machine causes the arc after the bend to be not smooth and clear, and the deformation of the steel pipe is large
