Description

Technical Field

[0001] The utility model relates to the technical field of punching presses, in particular to a mechanical processing punching press convenient for blanking. Background Technique

[0002] The punching press is a very important stamping device in mechanical processing. After retrieval, the patent with the publication number of CN221184460U discloses a punching press convenient for blanking. When in use, by starting the motor, the rotating rod is driven to rotate through the power output shaft of the motor. The U-shaped rod is driven to rotate through the rotation of the rotating rod. The movable connecting rod is driven to move up and down through the U-shaped rod. The lifting block and the pressing block are driven to move up and down through the movable connecting rod. The material is punched by the pressing block. At the same time, the grooved wheel and the belt are driven to rotate through the rotation of the rotating rod. The rotating rod and the corrugated roller are driven to rotate by the adjacent grooved wheels. Due to the limiting effect of the movable collar on the connecting bar and the limiting bar, the movable collar is driven to move left and right when the corrugated roller rotates. The push rod is driven to move left and right through the connecting bar. The push block is driven by the push rod, and the material is pushed out of the material by the push block. The material is placed in the inner cavity of the feeding pipe, and the electric telescopic rod is started. The feeding plate and the material are pushed into the inner cavity of the discharging pipe through the power output of the electric telescopic rod. However, its loading and unloading and stamping processes cannot be carried out synchronously, and are driven separately in sequence, with high energy consumption and low processing efficiency. Therefore, a mechanical processing punching press convenient for blanking is designed to synchronize the loading and unloading during the stamping process, reduce energy consumption, improve processing efficiency, and reduce production costs and maintenance costs.

[0012] (III) Beneficial effects

[0013] Compared with the prior art, the present utility model provides a mechanical processing punching machine facilitating blanking, having the following beneficial effects:

[0014] The mechanical processing punch press facilitating blanking places multiple workpieces to be punched in a row at the loading hole. Through the setting of the unidirectional rotating material feeding transmission mechanism, when the punching block in the punching mechanism moves upward to drive the material feeding disk to rotate, the workpiece to be punched in the workpiece limiting through groove at the loading station rotates towards the punching station. During punching, the punching block descends to punch the workpiece that has moved to the punching station. While the punching block is descending, due to the cooperation of the unidirectional rotating material feeding transmission mechanism, there is still a tendency for the material feeding disk to rotate counterclockwise. Due to the cooperation of the unidirectional movement mechanism, the reverse rotation of the material feeding disk is prevented, improving the stability during the punching moment. After punching is completed, as the punching block rises, the workpiece at the punching station moves to the unloading station and falls out through the blanking port. It punches stably when descending and performs material feeding operation when rising. This mechanical processing punch press facilitating blanking is convenient for synchronous loading and unloading during the punching process, reducing energy consumption while improving processing efficiency and reducing production costs and maintenance costs.

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0022] Embodiment:

[0023] Please refer to Figures 1-5 , a mechanical processing punch press facilitating blanking, which includes a stamping operation table 1. A dial 3 with at least three workpiece limiting through slots 5 circumferentially and uniformly arranged is rotatably connected to the top of the stamping operation table 1. On the stamping operation table 1, a loading station, a stamping station, and a unloading station adapted to three of the workpiece limiting through slots 5 are circumferentially arranged. A limiting cover 2 fixedly connected to the stamping operation table 1 is covered on the top of the dial 3. Loading holes and stamping through holes adapted to the workpiece limiting through slots 5 are respectively opened on the limiting cover 2 at the loading station and the stamping station. A stamping mechanism is arranged above the stamping station. The stamping mechanism includes a stamping block 9 that can be lifted and lowered. A stamping hole 4 adapted to the stamping block 9 is arranged on the stamping operation table 1 at the stamping station. A blanking opening adapted to the workpiece limiting through slots 5 is opened on the stamping operation table 1 at the unloading station. A one-way rotating dial driving mechanism capable of driving the dial 3 to rotate during the upward movement of the stamping block 9 is arranged between the tops of the dial 3 and the stamping block 9. A one-way movement mechanism 12 is arranged between the bottom of the dial 3 and the stamping operation table 1. The one-way movement mechanism 12 can also be set as a ratchet mechanism, an escapement mechanism, or a Geneva wheel mechanism, so as to prevent the situation that the stamping block 9 drives the dial 3 to rotate during the downward movement. Further, the screw sleeve rod 11 is rotatably connected to the limiting cover 2.

[0024] Specifically, the unidirectional rotation feeding transmission mechanism includes a screw sleeve rod 11 fixedly connected to the top of the feeding disc 3. A screw column 13 is threadedly connected inside the screw sleeve rod 11. A vertical chute 14 is opened at the inner top of the screw column 13. A sliding disc 15 is slidably fitted in the vertical chute 14. A plurality of clamping columns 16 with arc-shaped tops are circumferentially fixedly connected to the top of the sliding disc 15. A sliding rod 17 slidably fitted with the top of the screw column 13 is fixedly connected to the top of the sliding disc 15 at the middle position among the plurality of clamping columns 16. Positioning card slots adapted to the plurality of clamping columns 16 are circumferentially opened at the inner top of the vertical chute 14. The top of the sliding rod 17 is fixedly connected to the top of the stamping block 9 through a lifting sliding frame 10. Due to the cooperation of the screw sleeve rod 11, the screw column 13, the vertical chute 14, and the sliding disc 15, when the stamping block 9 rises, the sliding rod 17, the sliding disc 15, and the plurality of clamping columns 16 are synchronously driven to rise through the lifting sliding frame 10. When rising to drive the plurality of clamping columns 16 to be clamped into the plurality of positioning card slots, the screw column 13 is driven to rise synchronously. Due to the meshing of the screw column 13 and the screw sleeve rod 11, the screw sleeve rod 11 is driven to rotate, synchronously driving the feeding disc 3 to rotate, thereby facilitating the rotation of the workpiece limiting through slot 5 at the loading station to the stamping station. The workpiece limiting through slot 5 at the stamping station moves towards the unloading station, and is convenient to rotate to the loading station after unloading. When the stamping block 9 descends, the clamping columns 16 slide out of the plurality of positioning card slots, and the sliding disc 15 abuts against the screw column 13 to move downward. While moving downward, the rotational cooperation between the sliding disc 15 and the vertical chute 14 enables the screw column 13 to rotate while descending, and with the cooperation of the unidirectional motion mechanism 12, the reverse rotation of the screw sleeve rod 11 is prevented.

[0025] Specifically, the stamping mechanism further includes a top frame 7 fixedly installed above the stamping operation table 1. A lifting driving cylinder 8 is vertically fixedly installed on the top frame 7. The bottom output end of the lifting driving cylinder 8 is fixedly installed with a mounting plate. The top of the stamping block 9 is fixedly installed on the mounting plate at a position directly below the bottom output end of the lifting driving cylinder 8. The lifting sliding frame 10 is fixedly connected to the mounting plate. Through the cooperation of the top frame 7, the lifting driving cylinder 8, and the mounting plate, it is convenient to drive the stamping block 9 and the lifting sliding frame 10 to perform lifting movement, ensuring the stability of the stamping of the stamping block 9.

[0026] Specifically, the lifting sliding frame 10 is vertically slidably fitted with the top frame 7. Through the setting of the lifting sliding frame 10, the stability of the screw column 13 during lifting and the transmission stability of the unidirectional rotation feeding transmission mechanism are increased.

[0027] Specifically, an upper auxiliary unloading pressing opening is opened at the unloading station on the limiting cover 2. By opening the upper auxiliary unloading pressing opening on the limiting cover 2, it is convenient to press down the workpiece when the unloading is not smooth.

[0028] Specifically, a workpiece guiding groove 6 is fixedly connected to the top of the loading hole. Through the setting of the workpiece guiding groove 6, it is convenient to guide the workpiece and facilitate loading the workpiece to the loading hole.
