Description

Technical Field

[0001] The invention relates to iron can accessories processing equipment, in particular to screw nozzle stretching and ring cutting integrated processing equipment. Background Art

[0002] In the production process of iron cans, a split processing method is currently mostly used to process the various parts of the iron can structure, and then install the various parts of the structure as a whole. The top surface of the iron pipe is a structure with a screw nozzle, which is used to pour out the substances in the iron can. The processing of the top surface of the iron can is more complicated and requires many steps than other parts of the structure. It is necessary to first stamp out the opening structure of the iron can top surface and its assembly screw nozzle, and then press the screw nozzle into the opening structure of the iron can top surface in the equipment to form an overall structure of the iron can top surface and then install it in the iron can. The forming processing method of the screw nozzle is currently more cumbersome because the structure of the screw nozzle is complex. It has a double-layer installation end face that needs to be pressed into the opening structure of the iron can top surface. The outer layer of the double-layer installation end face is an oblique annular layer pressed into the back side of the iron can top surface, and the inner layer of the double-layer installation end face is a sealing layer pressed on the surface of the iron can top surface, and a threaded structure needs to be stretched out to screw into the tank cap.

[0003] There are many ways to process screw nozzles at present, but they still require various cumbersome processes and multiple equipment for separate processing, which results in the frequent transfer and transportation of accessories, consuming the cost and time of multiple conveyor belts. For example, the iron pipes for producing screw nozzles need to be sent to the blanking machine for cutting into iron pipe sections of equal length, and then the iron pipe sections are transferred to the stretching machine for installation end face for stretching, and finally the iron pipe sections with completed stretching end face need to be transferred to the surface thread stretching machine for processing.

[0044] The installation and adjustment method of the screw nozzle stretching and circular cutting integrated processing equipment is as follows: the first equipment compartment 1 and the second equipment compartment 2 of the screw nozzle stretching and circular cutting integrated processing equipment are installed on the left side of the desktop pipe pushing machine, so that the pipe outlet of the desktop pipe pushing machine is facing the vertical processing area of ​​the stroke of the first equipment compartment 1 and the second equipment compartment 2, and the pipe outlet center of the pipe pushing machine and the rotation center of the upper first drive motor 73 are on the same horizontal plane, so that the pipe can be covered with the internal stretching mold group 74 after the pipe pushing machine discharges the pipe; according to the length required for the production of the screw nozzle, the installation position of the laser cutting machine 3 in the second equipment compartment 2 is adjusted, so that when the pipe pushing machine pushes the iron pipe to a certain distance from the right side of the first equipment compartment 1, the laser cutting machine 3 can be directly above the required cutting length of the screw nozzle.

[0045] The method and process of processing an iron can into a screw nozzle by the screw nozzle stretching and ring cutting integrated processing equipment: pushing pipe feeding: controlling the pipe pushing machine to push the pipe to the left to a certain distance on the right side of the first equipment cabin 1, at this time controlling the first electric slide rail 4 to start, so that the first electric slide rail 4 drives the intermediate frame 5 and its accessories, the internal stretching die set 74 and the internal thread die set 75 to move to the right side and extend out of the processing port structure of the first equipment cabin 1, and at this time the internal stretching die set 74 extends into the interior of the iron pipe. Stretching processing of the screw nozzle installation end face: control the first hydraulic cylinder 83 to start, so that the first hydraulic cylinder 83 drives the propulsion frame 82 to move backward, so that the propulsion frame 82 drives the first drive motor 73, the inner stretching die set 74 and the inner thread die set 75 to move backward, so that the rear side edge of the inner stretching die set 74 contacts the inner peripheral rear wall of the iron pipe, and at the same time, start the second hydraulic cylinder 104, the second hydraulic cylinder 104 will drive the feed frame 103 to move forward, and the feed frame 103 will drive the second drive motor 93, the outer stretching die set 94 and the outer thread die set 95 to move forward, so that the front side edge of the outer stretching die set 94 contacts the outer peripheral rear wall of the iron pipe. At this time, the first hydraulic cylinder 83 and the second hydraulic cylinder 104 are controlled by the numerical control system to operate, so that the iron pipe does not produce displacement. Under this circumstance, the inner stretching die set 74 cooperates with the outer stretching die set 94 to stretch and form the screw nozzle mounting surface of the iron pipe, forming a protruding structure on the screw nozzle mounting surface for assembly on the top surface of the iron can, and forming an inclined stretching structure on the screw nozzle mounting surface for assembly on the back side of the top surface of the iron can; after the stretching processing of the installation end surface of the iron pipe is completed, the first hydraulic cylinder 83 and the second hydraulic cylinder 104 are controlled to reset, so that the inner stretching die set 74 moves to the front side for reset, and the outer stretching die set 94 moves to the rear side for reset. In this way, the stretching processing of the installation end surface of an iron pipe is completed, and then the first electric slide rail 4 is controlled to operate, so that the first electric slide rail 4 drives the inner stretching die set 74 and the internal thread die set 75 to move to the left and extend into the first equipment cabin 1 for reset. Iron pipe ring cutting: After the inner stretching die set 74 and the inner thread die set 75 are moved to the left and inserted into the first equipment compartment 1 for resetting, the iron pipe can be rotated for one circle, and the laser cutting machine 3 is started to ring cut the iron pipe, and the iron pipe with the installation end face processed after ring cutting can be separated from its main body.Thread drawing processing of the threaded section of the screw nozzle: after the processed iron pipe is ring-cut, the first electric slide rail 4 can be started again, so that the first electric slide rail 4 drives the inner drawing die set 74 and the inner thread die set 75 to move to the right side and extend out of the first equipment compartment 1 again, and the pipe pusher is started to push in a new section of the iron pipe again and perform the drawing processing of the screw nozzle installation end face as described above; while the inner thread die set 75 moves to the right and extends out of the first equipment compartment 1, the iron pipe sleeve with the installation end face completed after ring cutting can be placed on the inner thread die set 75, as in the above-mentioned drawing processing process of the screw nozzle installation end face, the inner drawing die set 74 and the inner thread die set 75 are in the processing process of the drawing processing of the screw nozzle installation end face. 5 moves to the rear side, and the outer drawing die set 94 and the outer thread die set 95 move to the front side. Then, when the outer drawing die set 94 and the inner drawing die set 74 are drawing the next section of the iron pipe, the inner thread die set 75 and the outer thread die set 95 will draw and form the iron pipe that has been drawn. After that, as mentioned above, the inner drawing die set 74 and the inner thread die set 75 are moved to the front side and reset. At this time, the screw nozzle that has been processed with the thread can be taken out. In this way, the drawing process of the installation end face of the screw nozzle and the thread drawing process can be quickly completed, so as to achieve the purpose of integrated processing and forming of the screw nozzle.

[0046] The screw nozzle stretching and ring cutting integrated processing equipment has an adjustment method for adapting to different pipes and processing requirements: in order to adapt to pipes of different diameters and different processing styles of installation end faces and threads, the inner stretching die set 74, the inner thread die set 75, the outer stretching die set 94 and the outer thread die set 95 that adapt to the diameter, installation end face style and thread style of the processing pipe can be loaded and unloaded at the connecting flanges of the first drive motor 73 and the second drive motor 93 according to the diameter, installation end face style and thread style of the processing pipe, and the precise installation position can be adjusted; thereafter, the first screw rod pair 84 and the second screw rod pair 105 at the upper and lower positions can be rotated to make the rear side edges of the inner stretching die set 74 and the inner thread die set 75 on the same vertical line, so that the inner stretching die set 74 and the inner thread die set 75 can be both When the iron pipe is in the iron pipe set, the first hydraulic cylinder 83 can be used to push the rear side edges of the inner stretching die set 74 and the inner thread die set 75 to contact the inner rear side of the iron pipe at the same time. This adjustment method can facilitate the precise adjustment of the outer stretching die set 94 and the outer thread die set 95. The stroke difference between the outer stretching die set 94 and the outer thread die set 95 can be adjusted by adjusting the second screw pair 105. During the synchronous pushing process of the outer stretching die set 94 and the outer thread die set 95 by the second hydraulic cylinder 104, the outer stretching die set 94 and the outer thread die set 95 can finally effectively cooperate with the inner stretching die set 74 and the inner thread die set 75 to complete the synchronous processing of the two iron pipes, and the second screw pair 105 is controlled to adjust the stroke of the outer stretching die set 94 and the outer thread die set 95.

The guide device 11 includes an integral guide plate 111, a split guide plate 112 and a material dividing mechanism 12. The guide device 11 is arranged in the processing area formed between the first equipment cabin 1 and the second equipment cabin 2. The guide device 11 is used to guide the iron pipe after the processing of the installation end face and the ring cutting to slide accurately to the position between the internal thread mold set 75 and the external thread mold set 95, so that the internal thread mold set 75 can directly extend into the section of the iron pipe. The guide device 11 can quickly put the iron pipe in place without manual assembly, which can improve the accuracy and yield rate of the screw nozzle production. The integral guide plate 111 is fixedly connected to the front position on the right side of the first equipment cabin 1, and the split guide plate 112 is fixedly connected to the front side of the second equipment cabin 2. The integral guide plate 111 and the split guide plate 112 are detachable and replaceable. The integral guide plate 111 and the split guide plate 112 are guide structures according to the outer structure of the iron pipe whose installation end face has been processed. The iron pipe section after ring cutting can be passed through The integral guide plate 111 and the split guide plate 112 are used for guiding the sliding of the iron pipe. If it is necessary to guide the different outer structures of the iron pipe, the integral guide plate 111 and the split guide plate 112 can be disassembled and replaced. A material distribution mechanism 12 is provided on the right side of the first equipment cabin 1. The material distribution mechanism 12 can collect and position the iron pipe section that has been slid down. The positioning method of the material distribution mechanism 12 is set according to the outer structure of the iron pipe whose installation end face has been processed. It is replaceable and slides down from the integral guide plate 111 and the split guide plate 112. The iron pipe section will fall on the dividing mechanism 12, and the dividing mechanism 12 can accurately position the iron pipe section that slides therein within the processing range of the internal thread mold group 75 and the external thread mold group 95. When the internal thread mold group 75 moves rearward and the external thread mold group 95 moves forward, the internal thread mold group 75 and the external thread mold group 95 will accurately perform thread stretching and forming on the iron pipe section. After the internal thread mold group 75 extends to the left into the first equipment compartment 1, the dividing mechanism 12 can be controlled to unload the screw nozzle after processing.

[0048] like Figure 12-14As shown, the material distribution mechanism 12 includes a material distribution motor 121, a limit frame 122 and a material suction electromagnet 123. The material distribution motor 121 is fixedly connected to the right side of the first equipment cabin 1 and is located in front of the integral guide plate 111. The material distribution motor 121 is a double-axis motor. The output shaft of the material distribution motor 121 is a structure with a connecting flange. The limit frame 122 is detachably installed at the connecting flange structure of the material distribution motor 121. The structure of the limit frame 122 is set according to the outer structure of the iron pipe whose installation end face has been processed. The limit frame 122 is detachable and replaceable to be suitable for the processing of different screw nozzles. The limit frame 122 is internally installed with a material suction electromagnet 123. The material suction electromagnet 1 23 is used to fix the iron pipe section that falls here for precise positioning and position stabilization. The iron pipe section that falls at the limit frame 122 is stabilized by starting the suction electromagnet 123. When the iron pipe section needs to be stretched on the threaded section, the suction of the suction electromagnet 123 can be disconnected, so that the iron pipe section is stretched by the internal thread mold group 75 and the external thread mold group 95. After the thread stretching processing of the iron pipe section is completed, and the internal thread mold group 75 is controlled to enter the first equipment cabin 1 to the left, the material distribution motor 121 can be started, so that the material distribution motor 121 drives the limit frame 122 to flip, so that the screw nozzle at the limit frame 122 is withdrawn, and the processed screw nozzle can be collected at this time.

[0049] like Fig. 20 As shown, it also includes a rotating device 13, which includes a mounting ring 131, an annular electric slide rail 132, a second electric slide rail 133 and a clamping plate 134. The rotating device 13 is arranged on the right side of the front side of the second equipment compartment 2. The rotating device 13 is used to drive the iron pipe to actively rotate and be ring-cut, and does not require manual operation to rotate, and provides stability when the iron pipe is driven to rotate by the inner stretching die set 74 and the outer stretching die set 94 during the end face stretching processing of the screw nozzle installation. The mounting ring 131 is fixedly connected to the right side of the front side of the second equipment compartment 2, and the right side of the mounting ring 131 is fixedly connected to the annular electric slide rail 132, and the right side of the moving part of the annular electric slide rail 132 is fixedly connected to Two second electric slide rails 133 are installed opposite to each other, and the moving parts of the second electric slide rails 133 are fixedly connected with clamping plates 134. The clamping plates 134 are replaceable. When it is necessary to control the rotation of the iron pipe, the second electric slide rail 133 can be started to make the second electric slide rail 133 drive the clamping plates 134 to clamp the iron pipe, and the annular electric slide rail 132 can be started to drive the iron pipe to rotate. When the iron pipe is driven to rotate by the inner stretching die group 74 and the outer stretching die group 94, the self-locking of the annular electric slide rail 132 can be disconnected, so that the clamping plates 134 clamping the iron pipe can be rotated through the annular electric slide rail 132, thereby providing stability for the driven rotation of the iron pipe.
