DETAILED DESCRIPTION

[0012] like Figure 1-3 As shown, this embodiment provides an automatic punching device, including a base 3 and a punching seat 1, the punching seat 1 is connected to the driving mechanism, the driving mechanism drives the punching seat 1 to move upward or downward, a long material trough 31 is provided on the top of the base 3, a discharge hole 32 is provided on the bottom of the material trough 31, and a slope 4 is provided on one side of the base 3; the punching seat 1 is located above the base 3, and a punch 11 is provided on the bottom of the punching seat 1 corresponding to the discharge hole 32, and a support plate extending outward is provided on the side of the punching seat 1 corresponding to the slope 4, and a material removal rod 5 is rotatably connected to the support plate, and an elastic member 6 is installed between the material removal rod 5 and the punching seat 1, and the elastic member 6 is used to drive the material removal rod 5 to reset, and the material removal rod 5 is used to insert the punching hole of the material 2 and cooperate with the slope 4 to drive the material 2 to move forward; the base 3 is provided with a support frame 7 in the direction of the material 2, and the height of the support frame 7 is flush with the bottom of the material trough 31, and a locking mechanism is installed on the side of the support frame 7, and the locking mechanism is used to limit the material 2 from moving back.

[0013] Furthermore, the locking mechanism includes a support plate, which is fixedly connected to the support frame 7 , and an electric push rod 8 is installed on the support plate, and the electric push rod 8 is connected to the driving mechanism signal of the punching seat 1 .

[0014] Furthermore, the elastic member 6 is a tension spring or a rubber spring. Furthermore, the punching width of the material 2 is greater than the width of the material-moving rod 5 .

[0015] Furthermore, a vertical sliding surface 9 is provided at the bottom end of the inclined surface 4 , and when the material-moving rod 5 slides down the inclined surface 4 to the bottom, it is closely attached to the sliding surface 9 .

[0016] Furthermore, baffles are provided on both sides of the trough 31. Figure 3-5When the present invention is in use, the various components operate as follows: first, a few holes are punched at the front end of the material 2 through manual auxiliary operation, so that the locking mechanism can cooperate with the punched holes at the front end to achieve automatic locking, and then enter the automatic mode; in the automatic mode, each time the punching seat 1 moves downward, a signal is sent to the electric push rod 8 through the control system to retract and unlock the electric push rod 8. Since the position of the material push rod 5 is lower than the position of the punch 11, the material push rod 5 first passes through the punched holes and contacts the inclined surface 4. The punching seat 1 continues to move downward so that the material push rod 5 slides downward along the inclined surface 4 until it slides to the sliding surface 9. When the material push rod 5 is in a vertical state, a lateral movement is generated during the downward sliding of the push rod. The material 2 is moved forward a certain distance, and then the punching seat 1 continues to move downward to make the punch 11 punch through the discharge hole 32 to punch the material 2 once; the punched material block is discharged through the discharge hole 32, and then the punching seat 1 is ready to return. Each time the punching seat 1 returns, it sends a signal to the electric push rod 8 to extend the electric push rod 8. The electric push rod 8 will be stuck at the inner edge of the punching hole at the front end, so that when the punching seat 1 goes up, the material push rod 5 withdraws from the punching hole and cannot drive the material 2 to retreat; when the material push rod 5 is completely withdrawn, it is automatically reset by the rebound force of the elastic member 6, so that the next punching action can be performed. In this way, the automatic cycle action can realize continuous automatic punching.

[0017] The present invention can also be applied to continuous blanking operations of workpieces made of plastic material, such as the housing of a thermostat.
