[0002] Hydraulic punching machine is a kind of punching machine used for punching, stamping, forming, shallow drawing, shaping and pressure assembly of metal or non-metal parts. It is especially suitable for punching aluminum products, punching of die casting nozzles, shaping of mobile phone shells, trimming of mobile phone silicone buttons, leveling of silicon steel sheets, and burr treatment of plastic and rubber products.

[0003] In order to facilitate the cleaning of waste from hydraulic punching machines, existing punching machines are equipped with special blanking devices to clean up waste. For example, a hydraulic punching machine with a cleaning function is disclosed in announcement No. CN 213728755 U. In the above structure, waste can fall onto the conical table, so that the waste can automatically fall into the collection box for tracking and collection. During the use of the above blanking structure, the applicant found that after the above waste falls onto the conical table, when the surface of the waste fits the conical table, it is easy to be adsorbed on the conical table, resulting in waste accumulation. At this time, human intervention is required, and the blanking effect needs to be improved. At the same time, when the waste breaks away from the conical table and falls downward, the support column on the conical table may block the waste, resulting in accumulation of stamping waste. At this time, human intervention is also required for cleaning. In order to solve the above problems, a hydraulic punching machine with a cleaning function is proposed. Utility Model Content

[0025] refer to Figure 1 and Figure 2 As shown, a conical platform 6 is provided at the lower part of the lower punch die 5, and the support column 4 passes through the conical platform 6. When the workpiece is stamped, the workpiece waste can fall onto the conical platform 6 and then fall into the lower part of the punch machine frame 1 from the conical platform 6, thereby facilitating the collection and processing of the stamping waste and enabling the punch machine to have a cleaning function.

[0026] refer to Figure 2As shown, a material drop opening 20 is provided at the bottom of the punching machine frame 1. This material drop opening 20 facilitates the waste materials dropped from the upper part to fall into the collection box at the bottom of the punching machine frame 1.

[0027] refer to Figure 2 As shown, two guide rods 7 are fixedly connected to the top of the inner cavity of the conical platform 6, and two cross plates 8 are fixedly connected to the opposite side walls of the upper part of the support column 4. The guide rod 7 is slidably connected to the cross plate 8, and a spring 9 is inserted into the guide rod 7. The upper end of the spring 9 is fixedly connected to the conical platform 6, and the lower end of the spring 9 is fixedly connected to the cross plate 8. The upper part of the support column 4 is rotatably connected to a rotating shaft 10, and cams 11 are fixedly connected to both sides of the rotating shaft 10. A worm gear 12 is fixedly connected to one side of the rotating shaft 10. A motor 13 is fixedly connected to the outer wall of the support column 4. The motor 13 is connected to a worm 14 through an output shaft, and the worm 14 is connected to the worm gear 1 2 meshing, this structure drives the worm 14 to rotate by starting the motor 13, and the worm 14 drives the rotating shaft 10 on the worm wheel 12 to rotate on the support column 4, thereby driving the cams 11 on both sides to push the conical platform 6 to move up and down, and the guide rod 7 guides the up and down movement position of the conical platform 6, and the spring 9 pulls the conical platform 6 downward, so that the conical platform 6 always moves in accordance with the cam 11, thereby driving the conical platform 6 to shake up and down, thereby shaking off the waste accumulated on the conical platform 6, thereby preventing the waste from being adsorbed on the conical platform 6 and unable to be discharged, improving the discharge effect of the conical platform 6, and avoiding manual intervention.

[0031] refer to Figure 2 As shown, a closed square baffle 21 is fixedly connected to the top surface of the mounting plate 2 around the periphery, and the square baffle 21 is used to block the surroundings of the mounting plate 2, thereby preventing the falling stamping waste from bouncing onto the mounting plate 2.

[0032] It should be noted that the structure disclosed in the above embodiment is applied to a hydraulic punch press and belongs to a punch press auxiliary equipment.

[0033] The implementation principle of a hydraulic punching machine with a cleaning function in an embodiment of the present application is as follows: when in use, the hydraulic rod 15 is used to drive the upper punch die 17 on the pressure plate 16 to move downward and merge with the lower punch die 5 on the support column 4 for stamping, thereby realizing the stamping of the workpiece. During the stamping process, the waste can fall onto the conical table 6 and slide from the conical table 6 to the lower part of the punching machine frame 1, thereby facilitating the collection and treatment of the stamping waste, so that the punching machine has a cleaning function, and when the stamping waste falls, the triangular inclined surface of the support plate 3 is arranged so that the stamping waste falling on the support plate 3 can slide down along the inclined surface, thereby avoiding the stamping waste from accumulating on the support plate 3, thereby ensuring that the waste can be completely collected and avoiding manual intervention in cleaning the accumulated waste.

[0034] When the conical table 6 is blanking, the motor 13 can be started to drive the worm 14 to rotate, and the worm 14 drives the rotating shaft 10 on the worm wheel 12 to rotate on the support column 4, thereby driving the cams 11 on both sides to push the conical table 6 to move up and down, and the up and down movement position of the conical table 6 is guided by the guide rod 7, and the conical table 6 is pulled downward by the spring 9, so that the conical table 6 always moves in accordance with the cam 11, thereby driving the conical table 6 to shake up and down, thereby shaking off the waste accumulated on the conical table 6, thereby avoiding the waste being adsorbed on the conical table 6 and unable to be blanked, improving the blanking effect of the conical table 6, and avoiding manual intervention.
