[0021] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely explain the technical solutions in the embodiments of the present invention. It should be noted that the embodiments and features in the embodiments of the present invention can be combined with each other in the absence of conflict, and the embodiments described are only part of the embodiments of the present invention, not all of the embodiments.

[0022] See also Figure 1-3To describe this embodiment, a side hole punching device includes an upper die 1, a lower die 2 and a punching mechanism 4, wherein the upper die 1 is connected to the lower die 2, and the punching mechanism 4 is installed on the lower die 2 and is located between the upper die 1 and the lower die 2, and the punching mechanism 4 includes a punching pin 5, a first mechanical slider 6, a second mechanical slider 7, a linear guide rail 10 and a fixed groove 8, wherein the punching pin 5 is connected to the second mechanical slider 7, and the inclined surface at the bottom of the first mechanical slider 6 is fitted with the inclined surface at the top of the second mechanical slider 7, and the fixed groove 8 is arranged on the linear guide rail 10, and the second mechanical slider 7 is slidably connected to the linear guide rail 10.

[0023] A slide 11 is mounted on the linear guide rail 10 . A fixing seat 12 is provided on one side of the slide 11 . The fixing slot 8 is provided between the fixing seat 12 and the slide 11 .

[0024] The upper die 1 is connected to the lower die 2 via a spring pin 3 .

[0025] This embodiment takes the central control screen aluminum frame with 12 side holes as an example. Figure 2 As shown, except for two pairs of side holes with similar distances and consistent directions, the rest are punched by one punching mechanism 4, so there are 10 punching mechanisms 4 on the lower die 2. The bottom of the punching mechanism 4 adopts a linear guide 10 to ensure the stability of the punching position of the mold, and a contoured fixing groove 8 is formed between the slide 11 and the fixed seat 12. When the mechanical slider drives the punching pin 5 forward, the punching part of the workpiece can be clamped and fixed by the slide 11 and the fixed seat to further ensure the hole position and the verticality of the hole.

[0026] When the device is working, the product features are first aligned with the fixed groove 8, the upper mold 1 falls, the spring pin 3 contacts the product first, and gradually presses the product to be relatively flat, then the first mechanical slider 6 moves downward, and drives the second mechanical slider 7 to slide forward along the linear guide 10 through the inclined surface at the bottom and the inclined surface at the top of the second mechanical slider 7. The sliding of the second mechanical slider 7 drives the fixed seat 12 to move in the same direction at the same time. The fixed seat 12 first contacts the product, and then the fixed seat 12 can clamp the product to ensure the stability of the punching, and then the second mechanical slider 7 continues to drive the punch 5 to move forward until the second mechanical slider 7 reaches the end of the stroke, the punch 5 completes the punching, and then the upper mold 1 rises, the second mechanical slider 7 and the first mechanical slider 6 move back, and when the upper mold 1 is fully raised, the punching work cycle is completed.

[0027] The production of side holes by cold working side cutting can not only meet product requirements and improve production efficiency but also reduce mold maintenance and manufacturing costs. A contoured fixing groove 8 is formed between the slide 11 and the fixed seat 12. When the mechanical slider drives the punch forward, the punching part of the workpiece can be clamped and fixed by the slide and the fixed seat to further ensure the hole position and the verticality of the hole.

[0028] This device first addressed the low production efficiency caused by difficulties in side-hole casting. Production capacity has been restored to 500 pieces per eight hours, and the casting scrap rate has been reduced to 0.5%, significantly improving production efficiency. Before adopting this fixture, mold disassembly and cleaning took an average of approximately 10 hours per day, resulting in a more than 70% increase in efficiency. This fixture also provides product shaping, reducing product deformation from 2-3mm to less than 1mm.

[0029] There are several punching mechanisms 4, and the punching mechanisms can be detachably mounted on the upper end surface of the lower die 2. The number and arrangement of the punching mechanisms can be adjusted according to the positions of the holes required for different products, making the device widely applicable.

[0030] A blanking hole 9 is provided below the fixed groove 8. After punching, the waste material falls into the waste collection box through the blanking hole 9, completing the waste collection, improving the working environment, and preventing waste aluminum from clogging the fixed groove 8 and affecting the punching accuracy and efficiency.

[0031] A spring 13 is sleeved on the outside of the punch pin 5, one end of the spring 13 is connected to the end of the punch pin 5, and the other end is connected to the support plate. The support plate is installed on the lower die 2. After the punching is completed, the spring 13 drives the punch pin 5 to move back, and then drives the second mechanical slider 7 to move backward for reset.

[0032] The first mechanical slider 6 and the second mechanical slider 7 are both made of carbon steel S50C to ensure the stability of the effective punching stroke controlled by the mechanical sliders.

[0033] A device for processing mounting holes of the aluminum frame of a central control screen of an automobile, including a side hole punching device, which can be used to perform punching operations on similar aluminum shell products.
