[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] like Figures 1 to 5As shown, this utility model provides a one-time forming device for a flower drum body, including a base plate 1, a lower mold 2 installed on the base plate 1, an upper mold 3 arranged above the lower mold 2, a first hydraulic cylinder 4 connected to the top of the upper mold 3, a mounting bracket 5 connected to the first hydraulic cylinder 4, the bottom of the mounting bracket 5 being fixedly connected to the base plate 1, matching punches 6 arranged on the left and right sides of the upper mold 3 and the lower mold 2, the punches 6 being connected to a second hydraulic cylinder 7, the second hydraulic cylinder 7 being connected to a displacement component 8, the displacement component 8 being arranged on the base plate 1, and the displacement component 8 being connected to a high-pressure airflow cleaning component 9;

[0030] The displacement assembly 8 includes a lifting platform 801 located at the bottom of the second hydraulic cylinder 7. A cylinder 802 is connected to the bottom of the lifting platform 801, and a moving platform 803 is connected to the bottom of the cylinder 802. A guide rail 804 is installed on the base plate 1 at a position corresponding to the moving platform 803. The guide rail 804 is slidably connected to the moving platform 803. A fixed ear 805 is fixedly connected to one side of the moving platform 803. An electric telescopic rod 806 is connected to the fixed ear 805. The electric telescopic rod 806 is installed on the base plate 1 and can drive the second hydraulic cylinder 7 and the punch 6 to move up and down and back and forth, so that the two punches 6 set on the left and right can be used as clamps. With the displacement assembly 8, automated loading and unloading can be realized. Moreover, the original stamping structure is improved, saving manufacturing costs.

[0031] Specifically, the high-pressure airflow cleaning component 9 includes a high-pressure air source 901, which is typically supplied by an air compressor or high-pressure air tank. It can generate stable high-pressure gas with a pressure generally between 0.5-1.0 MPa or even higher to meet the power required to blow away debris. The outlet of the high-pressure air source 901 is connected to an airflow pipe 902, which is connected to multiple equidistant airflow discharge pipes 903. Multiple equidistant high-pressure nozzles 904 are provided at the top and bottom of the airflow discharge pipes 903. During material feeding, the high-pressure nozzles 904 can clean the debris in the inner cavity of the upper mold 3 and the lower mold 2, preventing some debris from affecting the quality of the product.

[0032] Furthermore, a high-pressure air source 901 is installed on a mobile platform 803, and a support frame 905 is fixed on the mobile platform 803 at a position corresponding to the airflow pipe 902. The support frame 905 is used to support and stabilize the airflow pipe 902 and the airflow discharge pipe 903.

[0033] Furthermore, a material rack 10 is provided on the front side of the upper mold 3 and the lower mold 2. The position and structure of the material rack 10 correspond to the punch 6, and the bottom of the material rack 10 is fixedly connected to the base plate 1.

[0034] It is worth noting that the material rack 10 includes an upper material tray 1001 and an lower material tray 1002, and uprights 1003 are fixedly connected to both sides of the upper material tray 1001 and the lower material tray 1002.

[0035] It is worth noting that the feeding end of the feeding plate 1001 is tilted upward at a certain angle so that the bar stock enters from the feeding end and rolls down to the lower end. The discharging end of the discharging plate 1002 is tilted downward at a certain angle so that it can roll away in time after the formed hub body is placed, thus realizing the unloading.

[0036] It is worth mentioning that a guide tube 11 is fixed on the mobile platform 803 at a position corresponding to the lifting platform 801. A guide rod 12 is installed inside the guide tube 11. The top end of the guide rod 12 is fixedly connected to the lifting platform 801, making the lifting platform 801 more stable when it is raised and lowered.

[0037] The first hydraulic cylinder 4, the second hydraulic cylinder 7, the air cylinder 802, and the electric telescopic rod 806 are existing technologies and will not be described in detail. In addition, this utility model also includes a power supply, a controller, and a switch, which are not the main technical points of this patent and will not be described in detail.

[0038] Working principle and process: The bar stock is placed in the loading tray 1001 of the material rack 10. The cylinder 802 of the displacement component 8 is activated, which in turn causes the lifting platform 801 to move the second hydraulic cylinder 7 and the punch 6 upward. The electric telescopic rod 806 is activated, which in turn causes the fixed lug 805 to move the moving platform 803. This causes the cylinder 802, the lifting platform 801, the second hydraulic cylinder 7, and the punch 6 to move back and forth until the two punches 6 are at the two ends of the bar stock on the loading tray 1001. The second hydraulic cylinder 7 is activated to bring the two punches 6 closer together to clamp the bar stock. The bar stock is then transported to the lower die 2 by the cylinder 802 and the electric telescopic rod 806, which allows the punches to reset. The first hydraulic cylinder 4 is activated, causing the upper mold 3 to move downwards. The second hydraulic cylinder 7 is activated, causing the punch 6 to move, thus stamping the bar stock into a hub body. During unloading, the displacement component 8 is used to transport the hub body to the unloading platen 1002. At the same time, the airflow discharge pipe 903 of the high-pressure airflow cleaning component 9 moves between the upper mold 3 and the lower mold 2. High-pressure gas is provided by the high-pressure air source 901, and after passing through the airflow pipe 902 and the airflow discharge pipe 903, it is ejected by the high-pressure nozzle 904. The high-speed airflow generates a strong impact and shearing force, which can blow away the debris attached to the inner surface of the mold cavity and in the gaps, allowing it to be discharged from the mold with the airflow, thereby achieving the purpose of cleaning the mold.
