Description

Technical Field

[0001] The present invention relates to the technical field of copper tube processing equipment, and in particular, to a bending-tube end forming-dotting integrated machine. Background Art

[0002] In the field of copper tube processing, as Figure 1 shown, the processing of copper tubes usually involves multiple main processes such as bending, flaring, necking, and dotting. Currently, the processing equipment commonly used in the industry is to sequentially transfer copper tubes to each independent work station for processing different processes. This traditional processing method has significant defects.

[0019] See Figures 1 to 3, this embodiment discloses a bending-pipe end forming-dotting integrated machine, which is composed of a feeding mechanism 100, a bending mechanism 200, a pipe end mechanism 300 and a dotting mechanism 400, and the feeding mechanism 100, the pipe end mechanism 300 and the dotting mechanism 400 are arranged around the bending mechanism 200. The feeding mechanism 100 orderly conveys the pipe materials to the bending mechanism 200, the bending mechanism 200 clamps and bends the pipe materials, the pipe end mechanism 300 expands or contracts the pipe ends of the pipe materials, and the dotting mechanism 400 dots the pipe materials. By highly integrating multiple key processes such as feeding, bending, pipe end forming and dotting in the process of pipe material processing, this bending-pipe end forming-dotting integrated machine effectively overcomes the problems of low processing accuracy and poor production efficiency caused by the scattered processes and frequent displacement of pipe materials in traditional pipe material processing equipment, and is especially suitable for the high-efficiency and high-precision processing of short pipes and non-standard copper pipes.

[0020] The feeding mechanism 100 includes a feeding component 110 and a pushing component 120. Among them, the feeding component 110 is composed of a vibrating feeding device 111 and a feeding channel 112. The vibrating feeding device 111 is arranged on the machine table 500, can carry multiple pipes to be processed, and orderly outputs the pipes in a fixed posture. The feeding end of the feeding channel 112 is communicated with the discharging end of the vibrating feeding device 111, and the discharging end of the feeding channel 112 is connected to the feeding end of the pushing component 120. The pipe materials can enter the pushing component 120 along the feeding channel 112 under the action of gravity. The pushing component 120 includes a feeding channel 121, a first pushing driving part 122, a pushing bearing seat 123, a second pushing driving part 124 and a pushing part 125. The feeding channel 121 extends along the Z-axis direction and is arranged on the machine table 500. Its feeding end receives the discharging end of the feeding channel 112. The first pushing driving part 122 is arranged on the machine table 500 and drives the pushing bearing seat 123 to move along the Y-axis direction. The pushing bearing seat 123 movably penetrates through the discharging end of the feeding channel 121 along the Y-axis direction. The second pushing driving part 124 is arranged on the pushing bearing seat 123 and drives the pushing part 125 to move along the X-axis direction. A material supporting position 1231 extending along the X-axis direction is arranged at the front end of the pushing bearing seat 123. The pushing part at the front end of the pushing part 125 is adapted to the pipe material and is used for inserting the pipe material.

[0021] The clamping and bending mechanism 200 integrates the functions of clamping and pipe bending. Compared with the traditional separate structure, it significantly reduces the number and complexity of mechanisms, thereby effectively reducing the manufacturing cost and maintenance cost of the equipment. Referring to the figure, the clamping and bending mechanism 200 includes a clamping and bending component 210 and a blank holding component 220. In the clamping and bending component 210, the pipe bending driving part 211 is arranged on the machine table 500. The output end of the pipe bending driving part 211 is connected to the clamping die carrier 215, which can drive the clamping die carrier 215 to rotate around the Y axis. The clamping die driving part 212 is arranged on the clamping die carrier 215. The first clamping die 213 is connected to the output end of the clamping die driving part 212. The second clamping die 214 is arranged on the clamping die carrier 215 and is opposite to the first clamping die 213. The clamping die driving part 212 can drive the first clamping die 213 and the second clamping die 214 to make relative linear motion in the XZ plane. The front ends of the first clamping die 213 and the second clamping die 214 are both provided with a clamping position extending linearly in the XZ plane for clamping the pipe. The blank holding driving part 221 of the blank holding component 220 is arranged on the machine table 500. The blank holding die 222 is connected to its output end and can make linear motion along the Y axis. The blank holding die 222 is arranged side by side with the first clamping die 213 in the initial state. The front end is provided with a blank holding position extending linearly along the X axis, which cooperates with the clamping position to realize the firm clamping of the pipe. During the whole pipe bending process, the position of the pipe in the clamping and bending mechanism 200 is relatively unchanged, avoiding the positioning error caused by frequent displacement, thereby greatly improving the precision of pipe bending and effectively ensuring the processing quality of copper pipes.

[0022] The pipe end mechanism 300 is composed of a displacement component 310 and a forming component 320. The displacement component 310 includes a first displacement driving part 311, a first displacement carrier 312, a second displacement driving part and a second displacement carrier 314. The first displacement driving part 311 is arranged on the machine table 500 and drives the first displacement carrier 312 to slide along the Y axis. The second displacement driving part 313 is arranged on the first displacement carrier 312 and drives the second displacement carrier 314 to slide along the X axis. The forming component 320 is arranged on the second displacement carrier 314. In addition, the displacement component 310 is also provided with a limit driving part 315 and a limit part for accurate positioning. The limit driving part 315 is arranged on the machine table 500. The limit part is connected to its output end, and the front end faces the first displacement carrier 312. The forming component 320 includes a forming driving part 321 and a forming die 322. The forming driving part 321 is arranged on the second displacement carrier 314. The forming die 322 is connected to its output end, and the die orifice faces the clamping and bending mechanism 200 and can be an expanding die or a reducing die for realizing the forming of the pipe end of the pipe. A blank discharging part 323 is arranged at the position where the second displacement carrier 314 faces the clamping and bending mechanism 200, and a blank discharging channel 510 is arranged on one side of the clamping and bending mechanism 200 to facilitate the blank discharging of the processed pipe.

[0023] The dotting mechanism 400 is arranged below the bending mechanism 200. It consists of a dotting driving part 410 and a dotting part 420 in the shape of a needle structure. The dotting driving part 410 is arranged on the machine table 500 to drive the dotting part 420 to perform dotting operations on the pipe end of the pipe.

[0024] During the working process, the vibrating feeding device 111 first carries multiple pipes to be processed and outputs the pipes in a fixed posture in an orderly manner. The pipes enter the feeding channel 121 under the action of gravity through the feeding channel 112. Subsequently, the first pushing driving part 122 drives the pushing bearing seat 123 to move along the Y-axis, so that the material supporting position 1231 is aligned with the output end of the feeding channel 121. After the pipe falls into the material supporting position 1231, the first pushing driving part 122 drives the pushing bearing seat 123 to move again, so that the material supporting position 1231 and the pipe are opposite to the bending mechanism 200. Then, the second pushing driving part 124 drives the pushing part 125 to move along the X-axis, and pushes the pipe in the material supporting position 1231 to the bending mechanism 200. One end of the pipe enters the material clamping position of the second clamping die 214. Immediately afterwards, the clamping die driving part 212 drives the first clamping die 213 and the second clamping die 214 to close the die, firmly clamping the pipe. At the same time, the pressing material driving part drives the pressing material part to press down, so that the other end of the pipe enters the pressing material position. After that, the second pushing driving part 124 drives the pushing part 125 to retreat.

[0025] After the pipe is clamped, the pipe bending driving part 211 drives the clamping die bearing seat 215 to drive the bending component 210 to rotate around the Y-axis. Under the abutting action of the pressing material position, the pipe is bent. During this process, due to the integrated design of the bending mechanism 200, the pipe completes the pipe bending action in a fixed clamping state, and the position remains stable, effectively avoiding the problem of accuracy loss caused by multiple displacements of traditional equipment, and ensuring the high-precision requirements of pipe bending processing. After bending, the first clamping die 213 and the second clamping die 214 remain in the closed die state to continue clamping the pipe. After that, the first displacement driving part 311 drives the first displacement bearing seat 312 to drive the relevant components to move along the Y-axis, so that the die orifice of the forming die 322 is aligned with the pipe end. The second movement driving part further drives the second displacement bearing seat 314 to drive the forming component 320 to move along the X-axis, so that the die orifice of the forming die 322 is inserted into the pipe end. The forming driving part 321 drives the forming die 322 to perform necking or flaring forming on the pipe end. After the forming is completed, the forming driving part 321 suspends driving, and the second movement driving part drives the second displacement bearing seat 314 to drive the forming component 320 to retreat.

[0026] After the forming process is completed, the dotting driving member 410 drives the dotting member 420 to dot the pipe end of the pipe. After completion, the dotting driving member 410 drives the dotting member 420 to retract. Then, the first displacement driving member 311 drives the first displacement carrier 312 to move along the Y-axis, aligning the blanking member 323 with the pipe end of the pipe. The clamping die driving member 212 drives the first clamping die 213 and the second clamping die 214 to open the die. The second moving driving member drives the second displacement carrier 314 to move along the X-axis, and the pipe is pushed to the blanking channel 510 through the blanking member 323 to achieve blanking. Finally, each component retracts to the initial position to prepare for processing the next pipe.

[0027] In summary, through the coordinated cooperation of each mechanism, especially the integrated innovative design of the bending mechanism, the present integrated bending-pipe end forming-dotting machine realizes the integrated continuous processing of processes such as pipe bending, pipe end forming, and dotting of pipes. While reducing the equipment cost, it reduces the number of displacements of the pipes during the processing, significantly improves the processing accuracy and production efficiency, and effectively meets the high-precision and high-efficiency requirements of modern copper pipe processing.
