Description

Technical Field

[0001] The invention belongs to the technical field of mechanical manufacturing, and in particular relates to a pipe bending and drawing machine. Background Art

[0002] In the machinery manufacturing industry, pipe bending machines are widely used to bend various pipe fittings so that the pipe fittings have the shape required by the design or can be connected smoothly. The commonly used pipe bending machines now usually include: hydraulic system, motor to control the hydraulic pressure into the hydraulic cylinder, pipe bending mechanism (or pipe bending mold) and relay. In the process of pipe bending, after the position of the mold is adjusted in advance, the pipe fitting is placed in the pipe bending mold for pipe bending operation. The pipe bending operation process is: start the motor to introduce the oil into the hydraulic cylinder, and the hydraulic cylinder pushes the pipe bending mold to make corresponding actions. The relay timing is used to control the action of some limit valves until the set bending time is reached. The bending operation of the pipe fitting is stopped and the finished product is taken out, thereby completing the bending operation of the pipe fitting. The drawing machine is an industrial equipment composed of mechanical equipment, lubrication equipment, electrical equipment, hydraulic and pneumatic systems, etc., and is a device for drawing metal materials. The drawing machine is a device used for drawing metal at room temperature. Its capacity is often expressed in terms of maximum drawing force. Drawing machines can be divided into chain drawing machines, hydraulic drawing machines and drum drawing machines according to their different structures.

[0003] However, in the process of processing workpieces, the pipe bending machine and the drawing machine are used as two independent devices, which requires multiple operators and cannot form a streamlined production, resulting in reduced work efficiency. In addition, the current pipe bending machine has the following problems when in use: when the electrical control components inside the machine box of the pipe bending machine are damaged, due to the limitation of the internal space, it is difficult for maintenance personnel to operate it during the maintenance process. The maintenance process is time-consuming and labor-intensive, which greatly reduces the work efficiency of maintenance personnel. Summary of the invention
