[0019] The present invention will be described in detail below with reference to the drawings.
[0020] Embodiment 1
[0021] Figure 1 - Figure 2 A bottle mouth curling machine involved in the present embodiment is schematically shown, which mainly includes a machine tool platform 1, a curling die 2 and a bottle clamping device 3 installed on the machine tool platform 1, and related control function buttons configured.
[0022] The machine tool platform 1 serves as the carrier of the entire device, providing the installation basis for the curling die 2 and the bottle clamping device 3. It includes a machine tool main spindle box 11 and a machine tool carriage 12. Among them, the machine tool main spindle box 11 is used to install the curling die 2, and the machine tool carriage 12 is used to install the bottle clamping device 3.
[0023] The curling die 2 is installed on the driving main spindle of the machine tool main spindle box 11 to receive the rotational torque from the main spindle. As Figure 4As shown, the curling die 2 includes a die table 21, a die head 22 and a ring groove 23. The die head 22 is a frustum protruding outward from the middle of the die table 21. The frustum is adapted to the mouth of the aluminum can, and the diameter at the distal end B relative to the die table 21 is slightly smaller than the diameter at the proximal end A. The ring groove 23 is opened on the die table 21 at the root of the die head 22.
[0024] The bottle clamping device 3 is installed on the lathe carriage 12 of the machine tool platform 1, so that the lathe carriage 12 can be used as a carrier for reciprocating sliding; as Figure 3 shown, the bottle clamping device 3 includes an opening and closing clamping cup 31, a proximity switch 32, a pneumatic clamping cylinder 33, an air delivery pipe 34, an air storage tank 35, electronic components and circuits, etc. Among them, the opening and closing clamping cup 31 includes an upper opening and closing cup and a lower opening and closing cup that cooperate up and down. The inner walls of the upper opening and closing cup and the lower opening and closing cup are both sprayed with anti-wear and anti-slip resin. A proximity switch 32 is installed in the lower opening and closing cup. The proximity switch 32 is used to sense whether the bottle body is placed inside the opening and closing clamping cup. When the bottle body is placed in the clamping cup, the air storage tank 35 outputs air power to the pneumatic clamping cylinder 33 through the air delivery pipe 34, and the pneumatic clamping cylinder 33 closes the opening and closing clamping cup 31. At the same time, the bottle clamping device 3 automatically advances. The pneumatic clamping cylinder 33 can make the opening and closing clamping cup 31 open and close better under the action of force through a conversion angle; the air storage tank is used to provide air source for the pneumatic clamping cylinder 33.
[0025] Three limit switches are arranged in the stroke of the lathe carriage 12. In this embodiment, they are respectively defined as limit switch one 12a, limit switch two 12b and limit switch three 12c. Among them, the limit switch two 12b is used to transmit a die start signal to control the curling die 2 to perform a curling action; the limit switch one 12a is used to transmit a die stop signal to control the curling die 2 to stop the curling action; the limit switch three 12c is used to control the action of the bottle clamping device 3.
[0026] The operation process of a bottle mouth curling machine in this embodiment is as follows:
[0027] When the bottle body is placed in the opening and closing clamping cup 31, after the proximity switch 32 senses it, the pneumatic clamping cylinder 33 controls the opening and closing clamping cup 31 to close. At the same time, the lathe carriage 12 drives the bottle clamping device 3 to move forward towards the die. When the lathe carriage 12 drives the bottle clamping device 3 to reach the position of the limit switch two 12b, the curling die 2 starts to rotate automatically to perform a curling operation on the bottle mouth. When the lathe carriage 12 drives the bottle clamping device 3 to reach the position of the limit switch one 12a, the curling is completed and the curling die 12 stops operating. At this time, the lathe carriage 12 drives the bottle clamping device 3 to retreat. When the lathe carriage 12 drives the bottle clamping device 3 to retreat to the limit switch three 12c, it stops, and at the same time the bottle clamping device 3 opens to take out the bottle body, completing the curling operation of one product.
[0028] The present utility model takes a machine tool as a carrier, on which a curling die and a bottle clamping device are installed. The curling die is processed from high-quality carbon steel, with high hardness and flexibility, meeting the strength required for product production and processing. Moreover, the die is finely processed, and the processed products not only meet the physical indicators but also are delicate and beautiful. After the position is adjusted, during the processing, only an aluminum bottle needs to be placed in the clamping cup, with the bottom of the bottle close to the bottom of the clamping cup. After the proximity switch senses it, it will instruct the clamping cup to automatically close and clamp, and move forward towards the curling die. When reaching the second limit switch, the curling die starts to rotate. After reaching the position of the first limit switch, the curling is completed, the curling die stops running, the bottle clamping device retreats. When retreating to the third limit switch, the bottle clamping device stops retreating, the clamping cup opens, and the bottle body is taken out. During the whole operation, the operator only needs to do two actions: one is to put in the semi-finished bottle body, and the other is to take out the finished bottle body. The operation is simple, convenient, stable, and the finished product rate is high.
[0029] The above implementation of the present utility model is only an example for clearly explaining the present utility model, rather than a limitation on the implementation mode of the present utility model. For those skilled in the art, based on the above description, different forms of changes or variations can be made. It is not necessary to enumerate all the implementation forms here. Any modification made within the principle of the present adaptation model should be included within the protection scope of the present utility model.
