Problems solved by technology

[0008] By setting more than two sets of clamping mechanisms composed of fixed clamping die inserts and movable clamping dies, that is, including at least one set of straight clamping dies and one set of copying clamping dies, the straight pipe section that needs to be bent out is relatively short For the two rounded corner structures, the first rounded corner structure can be clamped by the straight clamping mechanism to complete the bending operation of the first rounded corner structure, and then the first rounded corner structure part can be clamped by the profiling clamping mold mechanism to complete the bending operation. The bending operation of the second rounded corner structure to overcome the problem that the connecting straight pipe section between the two rounded corner structures is too short to be firmly clamped by the straight clamping mechanism

Embodiment 1

[0039] see Figure 1 to Figure 15 , the pipe bending machine includes a frame, a control unit, and a pipe bending device 1 and a feeding trolley controlled by the control unit installed on the frame; wherein, the pipe bending device 1 includes a round die unit 2, an anti-wrinkle die unit 3, Guide mold unit 4, clamping unit 5, swing arm unit and spindle unit.

[0040] In this embodiment, the control unit includes a processor, a memory, and a touch control screen. The processor receives instructions input by the operator through the touch control screen, and controls the action of the pipe bending device and the feeding trolley by executing the computer program stored in the memory. , to achieve pipe bending operation.

[0041] The main shaft unit includes a pipe bending main shaft (not shown in the figure) arranged axially along the Z axis and a pipe bending motor for driving the pipe bending main shaft to rotate around its own axis 10. The pipe bending motor mechanism costs t...

Embodiment 2

[0067] As a description of Embodiment 2 of the present invention, only the differences from Embodiment 1 above will be described below.

[0068] Such as figure 1 , figure 2 , image 3 and Figure 11 As shown, the inner end of the swing arm 8 is set rotatably around the axis 10 on the pipe bending main shaft driven by the pipe bending motor, while the bending mold tire 7 is fixed on the pipe bending main shaft, and a device for driving the swing arm is installed on the pipe bending device. 8. Oscillating drive for oscillating around the axis 10 relative to the elbow main shaft. That is, after the synchronous rotation coupling mechanism releases the coupling between the swing arm 8 and the bending mold tire 7, the pipe bending motor drives the bending mold tire 7 to rotate independently around the axis 10 through the pipe bending main shaft, and the swing driver drives the swing arm 8 to independently rotate around the axis 10 .

Embodiment 3

[0070] As an explanation of Embodiment 3 of the present invention, only the differences from Embodiment 1 above will be described below.

[0071] In the step S3 of removing the mold and changing the mold, control the synchronous rotation coupling mechanism to release the coupling between the bending mold tire and the swing arm, and then control the first rotation driver to drive the bending mold tire to rotate a predetermined distance in the direction of the bending pipe until the fixed clamping mold insert is lifted During the process, the tube blank can be avoided, and then the first lifting mechanism is controlled to lift and lower the fixed clamping mold insert to change the mold. This method is suitable for the case where the central angle of the first rounded corner structure is not large.

Abstract

The invention relates to a pipe bending machine and belongs to the technical field of pipe processing and treating. The pipe bending machine comprises a rack and a pipe bending device mounted on the rack. The pipe bending device comprises a round mould unit and a clamping unit, and the round mould unit comprises a bent mould provided with a mounting notch and fixed clamping mould inserts mounted at the mounting notch. The clamping unit comprises a movable clamping mould matched with the fixed clamping mould inserts. The fixed clamping mould inserts comprise the straight-shaped fixed clamping mould insert and the profile-shaped fixed clamping mould insert which are arranged in a laminated mode in the axial direction of the bent mould. A first lifting mechanism used for rising and falling ofthe fixed clamping mould inserts is arranged on the round mould unit. The movable clamping mould comprises a second lifting mechanism used for rising and falling of the movable clamping mould. On thebasis of design of the structure, the problem that in the prior art, two round corner structures with short connecting straight pipe sections are difficult to bend on a pipe billet can be effectivelysolved, the clamping firmness for the pipe billet can be guaranteed in the pipe bending process, and the pipe bending machine can be widely applied to the fields of air conditioners, aviation, shipsand the like.

Description

technical field [0001] The invention relates to pipe material processing equipment, in particular to a pipe bending machine. Background technique [0002] Pipe bending machines are widely used in air conditioners, automobiles, ships, aerospace and other industrial fields. They mainly include a frame, a control unit, a feeding trolley and a pipe bending device installed on the frame and controlled by the control unit. The pipe bending device mainly includes a round die unit and a clamping unit. [0003] Among them, the circular die unit includes a circular die, and the clamping die unit includes a movable clamping die. In order to improve the clamping firmness of the circular die and the movable clamping die to the tube blank, they are required to clamp a long section of the end of the tube blank; therefore, The common circular die structure is designed as a U-shaped bending mold tire, such as the pipe bender disclosed in the patent document CN107282720A, or is designed to b...
