Description

Technical Field

[0001] The invention relates to the technical field of mechanical processing, and in particular to a fully automatic pipe bending device for automobile pipeline production. Background Art

[0002] Automobile fuel pipes can be either hard pipes or soft pipes, depending on the application location and function of the pipes. Hard pipes are mainly used to connect fixed parts to ensure the stability and reliability of the oil circuit; soft pipes are mainly used to connect moving parts to accommodate movement and reduce stress. For example, in the fuel system, the connection from the fuel tank to the fuel pump usually uses a soft pipe, but the connection from the fuel pump to the fuel filter usually uses a hard pipe.

[0003] At present, there are usually two processing methods for bending automobile oil pipes: (1) one or two workers use multiple sets of bending tools to perform multiple and continuous manual bending from the middle to the two ends; (2) use a double-head pipe bending machine to perform multiple and continuous automatic bending from the two ends to the middle. However, the manual bending method greatly increases the labor intensity of workers and has low work efficiency. The automatic bending method is very likely to cause the oil pipe to bend during the bending process, resulting in low bending accuracy. Summary of the invention

[0054] The working principle of this fully automatic tube bending equipment for automobile pipeline production:

[0055] Step 1: The motor five 506 drives the conveyor belt 505 to operate through belt transmission, and逐个向后输送 the rigid tubes to be bent, and then uses the finger cylinder two 408 to cooperate with the clamping block 409 to clamp the last rigid tube and transfer it to the positioning grooves 516a on the left and right sides;

[0056] Step 2: Use the finger cylinder two 408 to cooperate with the clamping block 409 to clamp the rigid tube in the positioning groove 516a, and then drive the clamped rigid tube to be placed in the movable grooves 202a on the left and right sides through the robotic arm 407;

[0057] Step 3: The cylinder 3 304 drives the clamping plate 306 to squeeze the clamping strip 307 and clamp the hard tube. At the same time, the finger cylinder 1 308 cooperates with the clamping block 309 to clamp the hard tube to prevent the hard tube from moving during bending.

[0058] Step 4: The double-axis cylinder 208 drives the limit block 1 213 to squeeze the limit block 214 and define the bending position of the hard tube, and then the double-axis cylinder 3 219 drives the bending block 225 to bend the hard tube at this position.

At the same time, the finger cylinder 2 408 cooperates with the clamping block 409 to clamp the bent hard tube part to prevent the hard tube from bending during bending.

[0059] Step 5: After the bending is completed, the clamped hard tube is automatically removed from the movable grooves 202a on the left and right sides by the robot arm 407.

[0060] Therefore, the embodiments disclosed above are only illustrative in all aspects and are not exclusive. All changes within the scope of the present invention or within the scope equivalent to the present invention are included in the present invention.
