Description

Technical Field

[0001] The utility model relates to the technical field of stamping dies, and more specifically to a stamping die with a replaceable stamping die head. Background Art

[0002] A stamping die is a special process equipment used to process materials into parts during cold stamping. It is called a cold stamping die. Stamping is a pressure processing method that uses a die installed on a press to apply pressure to the material at room temperature to cause separation or plastic deformation, thereby obtaining the desired parts.

[0003] In the prior art, for example, in the document with the announcement number CN218946110U, a stamping die with a replaceable stamping die head is specifically disclosed. In the document, the device pulls a clamp plate to slide horizontally, and when the clamp plate slides, the other clamp plate is driven to slide by the gear, so that the two clamp plates slide toward each other at the same time, so that the ends of the two clamp plates completely slide out of the annular limit groove, and the clamp plate limits the die head, so that the die head can be quickly pulled out;

[0004] However, the die head and the die are usually used in conjunction with each other. When a different type of die needs to be replaced, the die must also be replaced. Therefore, although the device can replace the die head, it cannot quickly replace the die. For this reason, we propose a replaceable stamping die head stamping die. Utility Model Content

[0005] Based on the above-mentioned technical problem in the prior art that, although the die head can be replaced, the die cannot be quickly replaced, the utility model proposes a stamping die with a replaceable stamping die head.

[0006] The utility model proposes a replaceable stamping die head stamping die, comprising a mounting seat, the top of the mounting seat is fixedly connected to a support block, the inner wall of the support block is threadedly connected to an adjusting screw, the end of the adjusting screw is rotatably connected to a first support plate, the inner wall of the first support plate is fixedly connected to a first sliding rod, the circumferential outer wall of the first sliding rod is sleeved with a first spring, the circumferential outer wall of the first sliding rod is slidably connected to a first support plate, the top of the mounting seat is slidably connected to a bottom die, a top die is provided above the bottom die, a first plug hole is opened on the side wall of the top die, a second plug hole is opened on the side wall of the bottom die, the end of the first support plate is plugged into the second plug hole and fixed by bolts, and the end of the first support plate is plugged into the inside of the first plug hole and fixed by bolts.

[0007] Preferably, one end of the first spring is fixedly connected to the first support plate, and the other end of the first spring is fixedly connected to the first support plate.

[0008] Preferably, a mounting plate is provided above the bottom mold, a hydraulic cylinder is fixedly connected to the top of the mounting plate, and an output end of the hydraulic cylinder passes through the mounting plate and extends to below the mounting plate.

[0009] Preferably, a second support plate is fixedly connected to the top of the mounting seat, the top of the second support plate is fixedly connected to the mounting plate, a second slide rod is fixedly connected to the inner wall of the second support plate, a second spring is sleeved on the circumferential outer wall of the second slide rod, a second support plate is slidably connected to the inner wall of the second support plate, the end of the second slide rod passes through the second support plate and is slidably connected to the second support plate, a clamping rod is fixedly connected to the end of the second support plate, a clamping hole is opened on the side wall of the top mold, and the clamping rod is plugged into the inner wall of the clamping hole.

[0010] Preferably, the output end of the hydraulic cylinder is fixedly connected with a ferrule, the inner wall of the ferrule is slidably connected with a block, and the bottom of the block is fixedly connected to the top of the top mold.

[0011] Preferably, the top of the mounting seat is symmetrically structured and fixedly connected with two limit blocks, the limit blocks are T-shaped, and two slide grooves are provided at the bottom of the bottom mold, and the two limit blocks are respectively connected to the inner walls of the slide grooves.

[0012] Preferably, a mounting groove is provided on the top of the mounting seat, a guide rod is fixedly connected to the inner wall of the mounting groove, a slider is slidably connected to the inner wall of the mounting groove, the end of the guide rod passes through the slider and is slidably connected to it, and the top of the slider is fixedly connected to the first support plate.

[0013] The beneficial effects of the present invention are:

[0014] 1. By rotating the adjusting screw, the first support plate is driven to move, and the bottom of the first support plate drives the slider to slide along the inner wall of the guide rod. The top mold and the bottom mold are pulled to move by the first support plate and the first support plate respectively, and the top mold and the bottom mold are moved out of the device, so that the bottom mold slides along the limit block, and the block on the top of the top mold slides out from the top mold. By disassembling the bolts on the top mold and the bottom mold, the top mold and the bottom mold can be easily disassembled.

[0015] 2. After replacement, rotate the adjusting screw in the opposite direction. At this time, the first support plate pushes the top mold and the bottom mold to move inside the device. At this time, the bottom mold slides along the limit block, and the limit block is used to limit and block the bottom mold, so that the bottom mold can be positioned.

[0016] 3. When the top mold moves, the card block on its top can slide into the inside of the card sleeve, and at the same time, the card hole on the top mold can be inserted into the card rod, thereby improving the stability of the top mold installation through the card rod.
