Description

Technical Field

[0001] The invention relates to the technical field of pipe processing, in particular to an automatic pipe chamfering and dotting forming machine. Background Art

[0002] Sprinklers and sprinklers are used for irrigation in home gardens and in agriculture to water plants when needed to aid cultivation, especially in environments where rainfall is insufficient, irregular or unreliable. They can also be applied to dust suppression, effluent diffusion, grey water recycling, roof cooling and bushfire ember protection. Sprinklers and sprinklers are in a variety of designs and sizes to suit a variety of uses, such as large farmland or small home gardens. In the case of large agricultural sprinkler systems, multiple sprinkler heads are usually distributed on a long supply pipe, and the spray assembly is usually self-propelled to travel on the field without farmer intervention.

[0003] One of the most commonly used is the easy-to-use swing-type rotary sprinkler, which includes a base and a spray pipe. When working, it uses water pressure as a power source to drive the spray pipe to swing. It has a large irrigation area and does not require manual supervision. Therefore, it is more popular in homes and small places. The spray pipe of this sprinkler is usually an aluminum pipe. Due to its special shape requirements, during production, a straight pipe needs to be chamfered on the inner and outer edges of the end, and then threads need to be tapped at the interface. Finally, the straight pipe needs to be pressed into a curved pipe before proceeding to the next step.

[0004] The traditional processing method for pipes is mostly step-by-step processing. Each step is processed on different mechanical equipment. After each processing is completed, it is manually transferred to the next step for processing. This processing method is relatively inefficient, the procedures are complicated and numerous, the labor intensity is high, and after each processing, it needs to be re-clamped and re-positioned for the next processing. The operation is relatively complicated, the yield rate is not high, and it is not conducive to mass production. In addition, the processing equipment is relatively numerous, the cost is increased, and it is not conducive to popularization.

[0005] Based on this, an automatic chamfering and dotting forming machine for pipes is proposed, which provides a new solution to the above technical problems. Summary of the invention

The degree of automation is high, which can greatly improve the efficiency of pipe processing, reduce manual labor intensity, and facilitate mass production. The structure is compact, and one device can complete multiple processing steps. The equipment occupies a small space, which is conducive to popularization.

[0064] Please refer to Figure 7 The distance adjustment component includes a first drive motor 107 installed at one end of the top of the working panel 902. The output end of the first drive motor 107 is connected to a first threaded rod 108. The first threaded rod 108 is rotatably connected to the top of the working panel 902. The outer side of the first threaded rod 108 is threadedly connected to a first mounting plate 109. The first mounting plate 109 is slidably connected to the working panel 902. When in use, starting the first drive motor 107 can drive the first threaded rod 108 to rotate, thereby driving the first mounting plate 109 to perform displacement movement.

[0065] Please refer to Figure 7 The feeding assembly includes a feeding plate 102 that is relatively arranged, a first support frame 101 is fixed on one side of the feeding plate 102, and the first support frames 101 on both sides are respectively installed on the top of the working panel 902 and the first mounting plate 109, and a flange 103 is provided at the bottom of the feeding plate 102.

[0087] The specific working principle of the automatic pipe chamfering and dotting forming machine provided by the present invention is:

[0088] When using this equipment, the staff first places a plurality of pipes to be processed between the two loading plates 102, and then starts the first cylinder 104 to adjust the position of the first limit plate 105, and the pipes will fall onto the conveying plate 112 through the flange 103 and the loading track 106, and then the third cylinder 111 is started to drive the conveying plate 112 and the pipe to move so that the end of the pipe is aligned with the second limit plate 113, and then the fourth cylinder 114 is started to press the pipe against the second limit plate 113, so as to position the pipe, and then the third cylinder 111 is started to press the pipe against the second limit plate 113, so as to position the pipe. The fifth cylinder 201 starts to drive the mobile mounting plate 202 to move as a whole, so that the first transport claw 205 close to the third cylinder 111 moves to the bottom of the pipe, and then the sixth cylinder 203 starts to drive the lifting mounting plate 204 to move upward, and at the same time, the first transport claw 205 starts to clamp the pipe, and then the sixth cylinder 203 starts again to make the first transport claw 205 rise, lift the pipe away from the conveying plate 112, and then the fifth cylinder 201 starts to drive the pipe to move to the next station close to the chamfering mechanism 300;

[0089] When the fifth cylinder 201 delivers the pipe to be processed to between the two chamfering heads 308, it stops, and then the sixth cylinder 203 starts again to drive the pipe to descend and put the pipe into the inner side of the chamfering processing groove, and then the sixth cylinder 203 starts to make the first transport claw 205 release the pipe and then descend to detach from the pipe, and then the seventh cylinder 312 starts to drive the clamping plate 313 to move, so that it clamps the pipe, and then the sixteenth cylinders 316 on both sides start to drive the second mounting plate 302 to move in the direction close to the pipe, so that the tool 315 gradually approaches and presses against the inner and outer sides of both ends of the pipe, and then the second driving motor 303 starts, and drives the first connecting rod 307 to rotate through the first pulley 304, the second pulley 305 and the first transmission belt 306, and then drives the chamfering head 308 to rotate through the first connecting rod 307, thereby driving the tool 315 to rotate, and the inner and outer sides of the opening of the pipe are chamfered by the rotation of the tool 315;

[0090] Then the fifth cylinder 201 starts again to carry the chamfered pipe to the top of the support roller 408, and then the third drive motor 411 starts to drive the fourth mounting plate 410 close to the pipe, and makes the second connecting rod 414 move towards the direction close to the thread head 405 after pressing against the pipe, so that the pipe is gradually sleeved on the thread head 405 and continues to move forward. During this process, the tenth cylinder 415 starts to clamp the pipe, and at the same time the eighth cylinder 402 starts to dot the end of the pipe, so that the dot position of the end of the pipe is located in the thread groove of the thread head 405. At the same time, the fourth drive motor 413 starts to drive the pipe to gradually rotate, so that it is gradually and completely sleeved on the thread head 405 while rotating. During this process, the eighth cylinder 402 dots the end of the pipe multiple times, so that the multiple dots are spirally distributed and coupled with the threads of the thread head 405.

[0091] When the dotting work is completed, the fifth cylinder 201 will start again to move the dotted pipe to the top of the support plate 421, and the seventeenth cylinder 423 will start to make the top plate 424 and the positioning plate 422 press the pipe to re-position it;

[0092] Then, the fifth driving motor 503 is started to drive the third pulley 504 to rotate. Due to the interaction between the third pulley 504, the guide wheel 505 and the second transmission belt 506, when the third pulley 504 rotates, the fifth mounting plate 502 as a whole moves along the fifth mounting frame 501, thereby driving the second transport claw 510 to move above the support plate 421. Then, the eleventh cylinder 507 is started to drive the second transport claw 510 to descend, and the second transport claw 510 grabs the dotted pipe. Then, the eleventh cylinder 507 is started again to drive the second transport claw 510 to descend, and the second transport claw 510 grabs the dotted pipe. The pipe is started to rise, and the rotating cylinder 509 is started to rotate the pipe 90 degrees. The fifth driving motor 503 transports the pipe while the twelfth cylinder 607 is started to drive the bottom plate 605 to move, thereby driving the lower mold 606 to move under the pipe. Then, the second transporting air claw 510 places the pipe on the lower mold 606, and the twelfth cylinder 607 is started to transport the lower mold 606 to under the upper mold 604. Then, the forming driving element 602 is started to drive the upper mold 604 to descend, and the pipe is formed by the upper mold 604 and the lower mold 606.

[0093] After the tube is formed, the twelfth cylinder 607 starts again to transport the lower mold 606 with the tube to between the two fifteenth cylinders 705, and then the fifteenth cylinder 705 starts to drive the push rod 706 close to the tube and extend it into the inside of the tube, and then the fourteenth cylinder 703 starts to drive the push rods 706 on both sides to rise and take the tube out from the inside of the lower mold 606, and then the thirteenth cylinder 701 starts to drive the seventh mounting plate 702, the fourteenth cylinder 703, the fifteenth cylinder 705 and the push rod 706 to move, thereby driving the tube to move, and when the tube is transported to the top of the lower hopper 707, the fifteenth cylinders 705 on both sides start again to make the push rod 706 separate from the tube, and the processed tube falls through the lower hopper 707 and is collected uniformly.
