Description

Technical Field

[0001] The utility model relates to the technical field of automatic production lines, and particularly relates to an automatic fixed-length cutting and marking device for rolling pipes. Background Art

[0002] During the cold rolling process of pipes, it is required to roll the whole pipe. After rolling, the length of the pipe increases by 4 to 6 times compared with that before rolling. At the same time, the outer diameter, wall thickness and inner diameter are all correspondingly reduced. Before the fixed-length cutting of the rolled pipes, a blanking rack is needed to transfer and store the pipes, so as to prepare for the cutting process; in addition, in order to facilitate the subsequent processing and inspection of the rolled pipes, it is also necessary to mark the ends of the fixed-length cut rolled pipes.

[0003] At present, the fixed-length cutting and marking of rolled pipes are mainly completed by using split equipment in a linear layout. However, the existing technology has a large floor area. During the processes of blanking, storage, cutting, marking, etc. of the rolled pipes, manual transportation is required, and additional personnel need to be arranged for the operation of each device, resulting in a high degree of manual participation and long time consumption. Therefore, it is necessary to design an automatic fixed-length cutting and marking device for rolling pipes with a small floor area and a high degree of automation.

[0004] In view of this, the inventor provides an automatic fixed-length cutting and marking device for rolling pipes to solve the above technical problems. Summary of the Utility Model

[0083] A sixth proximity switch 74 is provided on the marking conveyor rack 71 at a distance of 1500 mm from the marking device 73. When the sixth proximity switch 74 senses the cut pipe to be processed, the second belt conveyor member 72 conveys it to the right into the marking device 73 for marking. After marking, the second belt conveyor member 72 conveys the pipe to be processed to the left and flips it onto the storage rack 8 through the third dialing component 75;

[0084] Among them, the marking device 73, the second belt conveyor member 72, the sixth proximity switch 74, and all the third dialing components 75 are connected to the electrical control system.

[0085] Specifically, the marking device 73 is a pneumatic marking device, an off-the-shelf standardized device, which can complete the clamping and marking actions after receiving the marking signal.

[0086] As Figure 10 and Figure 11 shown, the first belt conveyor member 64 and the second belt conveyor member 72 have the same structure; the second dialing component 65 and the third dialing component 75 have the same structure;

[0087] Among them, the first belt conveyor 64 includes a driving motor 641, a synchronous belt, and multiple groups of belt conveyor structures 642. The driving motor 641 is connected to the multiple groups of belt conveyor structures 642 through the synchronous belt. Each group of the belt conveyor structures 642 includes a fifth base 6421, which is connected to the top of the cutting and blanking rack 61. Two sets of belt pulleys 6423 each sleeved with a belt 6422 are arranged on the upper part of the fifth base 6421, and the two belts 6422 form a V-shaped structure to transport the pipes to be cut, while providing sufficient support for the pipes. A transmission shaft 6424 is arranged at the lower part of the fifth base 6421. First bevel gears 6425 are respectively installed on both sides of the transmission shaft 6424. Second bevel gears 6426 are arranged on the outer teeth of the two first bevel gears 6425, and two sets of synchronous wheels 6427 are installed between the two first bevel gears 6425. Each of the belt conveyor structures 642 is connected through a synchronous belt; the driving motor 641 is connected to the electrical control system;

[0088] Each group of the second material pushing components 65 includes a second material pushing cylinder and a trapezoidal nylon block connected to the lever of the second material pushing cylinder. The second material pushing cylinder is arranged at the bottom of the cutting and blanking rack 61, and the trapezoidal nylon block is installed between the cutting and blanking rack 61 and the marking and conveying rack 71. The second material pushing cylinder is connected to the electrical control system.

[0089] The specific process of the device in actual application is as follows:

[0090] 1) Check the device to ensure that there are no foreign objects on and around the device. Move the fixed-length measurement component 67 to the specified position according to the position measured by the tape measure, and then supply power to the main control cabinet of the electrical control system to ensure that the first clamping and conveying mechanism 2 and the second clamping and conveying mechanism 5 are in the lowered state and the cutting device 63 is in the starting state;

[0091] 2) Place the pipe to be processed on the transition rack 1 and push it towards the first clamping and conveying mechanism 2. When the tail end of the pipe to be processed leaves the first proximity switch 13 and the second proximity switch 14 senses the top end of the pipe to be processed, the first clamping and conveying mechanism 2 lifts and clamps and transports the pipe to be processed onto the loading rack 13. When the tail end of the pipe to be processed leaves the second proximity switch 14, the first clamping and conveying mechanism 2 opens and drops, and the first material pushing component 32 flips the pipe to be processed into the current third L-shaped nylon block 41123 of the chain conveyor structure 4112 of the material lifting component 41;

[0092] 3) The chain conveyor structure 4112 moves upward until the seventh proximity switch senses the next third L-shaped nylon block 41123 and then stops moving;

[0093] Among them, a total of 2 pipes to be processed can be stored on the chain conveyor structure 4112. After the third pipe to be processed is flipped onto the third L-shaped nylon block 41123, the chain conveyor structure 4112 moves upward, and the pipe to be processed that was earliest placed on the third L-shaped nylon block 41123 falls onto the V-shaped nylon rollers 4211 of the cutting and conveying assembly 42;

[0094] 4) When the third proximity switch 4213 senses the pipe to be processed, the second clamping and conveying mechanism 5 lifts and clamps the pipe to be processed and transports it to the first belt conveyor 64 of the fixed-length cutting mechanism 6. The fixed-length stop block 674 of the fixed-length measuring assembly 67 drops, and the clamping mechanism of the cutting device 63 opens. When the fifth proximity switch 673 senses that the top end of the pipe to be processed is approaching, the second clamping and conveying mechanism 5 stops conveying, the clamping mechanism of the cutting device 63 clamps the pipe to be processed, and at the same time the fixed-length stop block 674 rises;

[0095] 5) The cutting device 63 cuts the pipe to be processed. After the cutting is completed, the cutting device 63 returns to its initial position. The first belt conveyor 64 conveys the pipe to be processed to the left. When the tail end of the pipe to be processed leaves the fourth proximity switch 68, the second material deflector assembly 65 flips it onto the second belt conveyor 72;

[0096] 6) The second belt conveyor 72 transports the pipe to be processed to the right. When the sixth proximity switch 74 senses the pipe to be processed, the second belt conveyor 72 stops transporting, and the marking device 73 automatically completes the marking work;

[0097] 7) After the marking is completed, the second belt conveyor 72 transports the pipe to be processed to the left. When the pipe to be processed leaves the sixth proximity switch 74, the second belt conveyor 72 stops transporting, and the third material deflector assembly 75 flips it onto the storage rack 8.

[0098] During continuous production, the device repeats the above process until the third proximity switch 4213 no longer senses the pipe to be processed and then stops.

[0099] The above are only the specific embodiments of the present invention, enabling those skilled in the art to understand or implement the present invention. Various modifications to these embodiments will be obvious to those skilled in the art. The general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention.
