[0020] Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative work shall fall within the scope of protection of the present invention.
[0021] See also Figure 1-5 , the utility model provides a technical solution.
[0022] A cold aluminum forming mechanism for a blister packaging machine, comprising a base 1; the base 1 is used to support the entire mechanism components, and is provided with a guide column 2, a guide hole 3, an assembly frame 4, a replaceable die assembly, and a stamping forming assembly;
[0023] The guide column 2 is installed on the base 1, the guide hole 3 is opened on the assembly frame 4, and the assembly frame 4 is sleeved on the guide column 2 through the guide hole 3;
[0024] The replaceable die assembly includes: a die template 5, a slide rail 6, a slideway 7, a buckle slot 8, a movable buckle 9, a return spring 10 and a baffle 11;
[0025] The slide rail 6 is installed on the die template 5, the slideway 7 is provided on the assembly frame 4, the die template 5 is installed on the slideway 7 via the slide rail 6, the buckle groove 8 is provided on the side of the assembly frame 4, the movable buckle 9 is installed in the buckle groove 8, the baffle 11 is connected to the movable buckle 9, and the return spring 10 is installed in the buckle groove 8 and abuts against the movable buckle 9;
[0026] It should be noted that before starting the cold aluminum forming manufacturing, the corresponding model of the die template 5 is installed on the slide 7 through the slide rail 6, and then the rear of the die template 5 is limited by the baffle 11, so as to complete the installation of the die template 5. When the die template 5 needs to be replaced, the baffle 11 can be lifted to make the movable buckle 9 rise in the buckle groove 8, and then the limit of the die template 5 can be released. Then the die template 5 can be removed, and the reset spring 10 can help the movable buckle 9 to reset;
[0027] The stamping forming assembly includes: a fixing frame 12, a stamping cylinder 13, a top plate 14, a through hole 15, a stamping head 16, a support spring 17 and a telescopic rod 18;
[0028] The fixing frame 12 is mounted on the base 1, the punching cylinder 13 is mounted on the top of the fixing frame 12, the top plate 14 is mounted on the telescopic end of the punching cylinder 13, the through hole 15 is opened on the assembly frame 4, the punching head 16 is mounted on the base 1 and aligned with the through hole 15, and the support spring 17 and the telescopic rod 18 are installed between the assembly frame 4 and the base 1;
[0029] It should be noted that when the stamping action begins, the stamping cylinder 13 is started, and then the assembly frame 4 can be pressed downward through the top plate 14 so that the punching head 16 passes through the through hole 15 and is pressed into the groove of the die template 5, thereby completing a stamping work. The support spring 17 and the telescopic rod 18 can help the assembly frame 4 to be stably reset. The punching head 16 is set to a bubble multi-layer angle design. If the punch is designed with an ordinary round punch design, then even under the same stretching area ratio, compared with the punch with a multi-layer angle design, the material stretching of the former is extremely uneven, and the bubble is very easy to break at the bottom, or the bottom of the bubble is very poor, affecting the appearance of the product.
[0030] As a preference, further, the rear of the die template 5 is flush with the side of the assembly frame 4 .
[0031] It should be noted that when the rear of the die template 5 is flush with the side of the assembly frame 4, the die template 5 can be prevented from shaking after installation.
[0032] Preferably, further, the support springs 17 are evenly distributed between the base 1 and the assembly frame 4 .
[0033] It should be noted that the distribution positions of the support springs 17 can ensure that the assembly rack 4 is subjected to uniform force and that the assembly rack 4 can be lifted and lowered stably.
[0034] Preferably, further, the material of the punch head 16 is set to be polytetrafluoroethylene.
[0035] It should be noted that the friction coefficient between the punch head 16 made of polytetrafluoroethylene and the aluminum plate is very low, which can minimize friction and wear and enhance punchability.
[0036] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
