Description

Technical Field

[0001] The utility model belongs to the technical field of punching dies, and particularly relates to a detachable die. Background Art

[0002] After the T-iron die in the workshop is used for a period of time, it needs to be replaced or cleaned. When processing different products, the T-iron die also needs to be replaced; when replacing or cleaning, the die needs to be removed from the installation platform of the punching press and then dragged out and transported to the outdoor field. The traditional die removal method is to manually remove the die and drag it out and place it on the trolley, and then transport it to the outdoor field to disassemble the die. Due to the heavy weight and large size of the die, the labor intensity of workers is relatively high, and there are also unsafe situations such as the die slipping and falling easily. Summary of the Invention

[0003] The utility model mainly solves the technical problems existing in the above-mentioned prior art, and provides a detachable die.

[0004] The above technical problems of the utility model are mainly solved by the following technical solutions: a detachable die, including a base and a replaceable die head. The base is cylindrical, two positioning planes are provided on the side surface of the base, two limiting sliding grooves are provided on the bottom surface of the base, an installation sunk platform is provided on the top surface of the base, a limiting sunk hole is provided at the center of the installation sunk platform, the limiting sunk hole and the installation sunk platform are coaxially arranged, and the installation sunk platform and the base are coaxially arranged. The limiting sunk hole is a tapered hole, and a plurality of die head locking screw holes are provided on the surface of the installation sunk platform, and the plurality of die head locking screw holes are annularly arranged along the axis of the installation sunk platform;

[0005] The replaceable die head includes a tapered portion matched with the limiting sunk hole and a panel arranged on the upper side of the tapered portion. The tapered portion and the panel are coaxially arranged. The replaceable die head is installed in the limiting sunk hole of the base through the tapered portion. A plurality of countersunk through holes are provided on the panel, and the plurality of countersunk through holes are arranged in one-to-one correspondence with the die head locking screw holes. A forming cavity is provided at the center position of the panel.

[0006] Preferably, there is a gap between the lower surface of the panel and the upper surface of the installation sunk platform.

[0007] Preferably, platform connection screw holes are provided on the positioning planes on both sides of the base.

[0008] Preferably, adjusting abutting arc holes are provided at the front and rear ends of the base.

[0009] The beneficial effects of the present utility model are as follows: By setting the die cavity part for stamping forming as a detachable die head, the whole die is divided into a base connected to the punching press and a replaceable die head for forming. When it needs to be cleaned after a period of use, only the replaceable die head needs to be removed, reducing the weight for replacement. And when different products need to be processed and the replaceable die head needs to be replaced, only the replaceable die head needs to be disassembled, reducing the labor intensity of workers. At the same time, the cooperation between the limit counterbore and the tapered part can be directly used after replacement without re-adjusting and centering positioning, greatly improving the processing efficiency.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0013] The technical solutions of the present utility model will be further specifically described below through embodiments and in conjunction with the drawings.

[0014] Embodiment: A detachable die, as Figure 1 - Figure 2 shown, includes a base 1 and a replaceable die head 2. The base 1 is cylindrical. Two positioning planes 3 are provided on the side surface of the base 1. Two limit chutes 4 are provided on the bottom surface of the base 1. A mounting sink 5 is provided on the top surface of the base 1. A limit counterbore 6 is provided at the center of the mounting sink 5. The limit counterbore 6 and the mounting sink 5 are coaxially arranged, and the mounting sink 5 and the base 1 are coaxially arranged. The limit counterbore 6 is a tapered hole. A plurality of die head locking screw holes 7 are provided on the surface of the mounting sink 5. The plurality of die head locking screw holes 7 are annularly arranged along the axis of the mounting sink 5;

[0015] The replaceable die head 2 includes a tapered part 8 that cooperates with the limit counterbore 6 and a panel 9 provided on the upper side of the tapered part 8. The tapered part 8 and the panel 9 are coaxially arranged. The replaceable die head 2 is installed in the limit counterbore 6 of the base 1 through the tapered part 8. A plurality of countersunk through holes 10 are provided on the panel 9. The plurality of countersunk through holes 10 are arranged in one-to-one correspondence with the die head locking screw holes 7. A forming cavity 11 is provided at the center position of the panel 9.

[0016] There is a gap between the lower surface of the panel 9 and the upper surface of the mounting counterbore 5. During the stamping process, the impact received will be directly transmitted to the limiting counterbore 6 of the base 1 through the tapered portion 8, avoiding deforming the panel 9 by acting on the panel 9. Platform connection screw holes 12 are provided on the positioning planes 3 on both sides of the base 1. Adjusting abutting arc holes 13 are provided at the front and rear ends of the base 1. During the first installation, the abutting arc holes can be abutted against by the screw on the punching press within the arc holes to adjust the vertical position of the base 1.
