technical field

The utility model relates to the field of stamping dies, in particular to an improved stamping die for preventing material return.

Background technique

Stamping dies are tools made of metal and other rigid materials for stamping and forming. Stamping is a pressure processing method that uses a mold installed on a press to apply pressure to the material at room temperature to cause separation or plastic deformation to obtain the required parts. Stamping die is an indispensable process equipment for stamping production, and it is a technology-intensive product. The quality, production efficiency and production cost of stamping parts are directly related to the design and manufacture of molds.

In the prior art, the following disadvantages generally exist for single punch dies:

The corresponding position of the lower mold base and the second waste through hole is provided with a waste storage tank, the waste storage tank is connected with the second waste through hole through a waste conduit, and the connection between the waste storage tank and the second waste through hole A second induction device and an air suction device are arranged at the place; the rotary cylinder, the first induction device, the second induction device and the air suction device are all connected with the control system.

As a preferred solution, the diameter of the first waste through hole is equal to the diameter of the second waste through hole.

As a preferred solution, there are at least 6 stamping grooves on the top surface of the rotating seat.

As a preferred solution, the waste conduit is set as a soft conduit.

As a preferred solution, the diameter of the first waste through hole is smaller than the diameter of the punching groove.

The beneficial effects of the utility model are:

First, after the upper pressing block completes a stamping action, the first sensing device sends an instruction to the rotary cylinder, and the rotary cylinder drives the rotary seat to rotate to the next punching hole to prepare for the next stamping action, which greatly improves the work of the single punching head mold efficient and simple in structure.

Second, after the stamping is completed, the waste material, under the force of the suction device, passes through the first waste through hole, the second waste through hole, and the waste conduit in turn and falls into the waste storage tank, thereby completing the automatic collection of waste without manual work The operation is troublesome, so as to ensure the stamping quality of the workpiece.

detailed description

The technical scheme of the present utility model is described below in conjunction with accompanying drawing and embodiment.

Referring to Fig. 1, Fig. 2 and Fig. 3, an improved stamping die includes a die 12, a punch 6 and a control system, the punch 6 is fixedly arranged on the bottom surface of the upper die base 1, and the punch The upper pressing block 7 is fixedly arranged in the middle cavity 16 of 6, and the die 12 is fixedly arranged on the top surface of the lower mold base 17, and the cavity 4 of the die 12 is provided with a lower backing plate 10. The backing plate 10 floats up and down in the cavity 4, and the lower backing plate 10 is connected to the bottom plate of the die 12 through the return spring 5, and the lower backing plate 10 includes a fixed seat 18 and a circular rotating seat 14 arranged in the fixed seat 18 , the rotating seat 14 is connected with a rotating cylinder 19 and the first induction device 8, and the top surface of the rotating seat 14 is provided with a number of circular punching grooves 9, and the number of the punching grooves 9 is at least 6. The central position of the stamping groove 9 is provided with a first waste material through hole 13, and the second waste material through hole 15 corresponding to the upper pressing block 7 is arranged in the fixed seat 18, and the lower mold base 17 is connected with the second waste material through hole 15. The position corresponding to the waste through hole 15 is provided with a waste storage tank 11, which is connected with the second waste through hole 15 by a waste conduit 3, and the waste storage tank 11 is connected to the second waste through hole 15. The connection is provided with a second induction device (not shown in the figure) and an air suction device 2; the rotary cylinder 19, the first induction device 8, the second induction device and the air suction device 2 are all connected to the control system.

Before stamping each time, the control system adjusts the stamping groove 9 to be directly below the upper pressing block 7 according to the preset program, the upper pressing block 7, the stamping groove 9, the first waste material through hole 13, the second waste material The through hole 15 and the waste conduit 3 are coaxial. After a stamping action is completed, the upper pressing block 7 rises, and the first induction device 8 sends an instruction to the rotating seat 14 to rotate the next punching groove 9 to the corresponding directly below the upper pressing block 7 to carry out the stamping action, and the cycle operation is like this.
