Description

Technical Field

[0001] This utility model belongs to the field of stamping die technology, and in particular relates to sheet metal stamping forming dies with quick die change capability. Background Technology

[0002] Stamping dies are special process equipment used in cold stamping to process materials into parts. Stamping is a pressure processing method that uses dies mounted on a press to apply pressure to materials at room temperature, causing them to separate or undergo plastic deformation, thereby obtaining the desired parts.

[0003] Because more than two screws are needed to secure the stamping die, multiple screws need to be operated with a screwdriver during disassembly, which makes replacing the stamping die relatively slow.

[0004] To address these issues, we propose a sheet metal stamping die with quick mold change capability. Utility Model Content

[0005] The purpose of this invention is to solve the problem of slow die replacement in sheet metal stamping, and to propose a quick-change die for sheet metal stamping.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A quick-change sheet metal stamping die includes a die body with a tray underneath. Threaded seats are symmetrically fixed to the sides of the tray, and bolts are threaded onto the upper parts of the threaded seats. An extrusion plate slides inside the tray and is embedded in the lower part of the die body. The bolts contact the extrusion plate. Loosening the bolts allows the die body to be pulled outwards, pushing the extrusion plate aside and retracting it into the tray, thus facilitating the removal of the die body. A new die body is then placed back in, and the bolts are tightened. This design ensures the stability of the die body while facilitating quick and easy replacement.

[0008] Preferably, the tray includes a tray body and a guide block. The guide block has a guide groove inside. The mold body is placed on the tray body, and the extrusion plate is slidably installed in the guide groove. The threaded seat is symmetrically fixedly connected to the side of the tray body. The guide groove guides the extrusion plate to slide, and the guide block blocks the side of the extrusion plate. The extrusion plate acts on the mold body, ensuring the stability of the mold body after installation.

[0009] Preferably, the guide block has a guide surface on the side facing the disk body. When installing the mold body, the guide surface is used to guide the mold body into the middle of the disk body, which facilitates the installation of the mold body.

[0010] Preferably, the threaded seat includes a fixed seat and a nut. The lower part of the fixed seat is fixedly connected to the side of the disc body, the bolt is threaded inside the nut, and the nut is fixedly connected to the upper part of the fixed seat. The nut guides the bolt to move helically, allowing the bolt to tighten or loosen the compression plate, facilitating helical control of the bolt.

[0011] Preferably, the bolt includes a threaded rod and a knob. One end of the threaded rod is fixedly connected to the side of the knob, and the threaded rod is threaded into a nut, passing through the nut. The knob increases the operating lever length of the threaded rod; manually turning the knob rotates the threaded rod, facilitating manual operation of the bolt.

[0012] Preferably, the bolt further includes a hemispherical block, and the knob is fixedly connected to the end of the threaded rod opposite to the knob. The hemispherical block is in movable contact with the extrusion plate. The hemispherical block's connection with the extrusion plate increases the stability of the stress point between the extrusion plate and the bolt.

[0013] Preferably, the extrusion plate includes a mating seat and a plate body. The mating seat has a groove on its side and is fixedly connected to the middle of the plate body. The lower end of the plate body is in movable contact with the tray. The side of the plate body is slidably engaged in a guide groove. The end of the plate body facing away from the mating seat is arc-shaped, and the arc-shaped end of the mating seat is engaged in the lower part of the mold body. When the threaded rod presses the groove through the hemispherical block, the mating seat acts on the tray, and the plate body is engaged in the lower part of the mold body, facilitating the locking of the mold body onto the tray.

[0014] In summary, the technical effects and advantages of this utility model are as follows:

[0015] 1. Loosen the bolts, then pull the mold body outward to push the extrusion plate outward and retract the extrusion plate into the tray, so that the mold body can be easily removed. Then put the new mold body back in, tighten the bolts, and ensure the stability of the mold body while facilitating quick replacement.

[0016] 2. The extrusion plate is guided to slide by the guide groove, and the guide block is used to block the side of the extrusion plate. The extrusion plate acts on the mold body to ensure the stability of the mold body after installation.

[0017] 3. When installing the mold body, use the guide surface to guide the mold body into the middle of the plate, which facilitates the installation of the mold body.

[0018] 4. Use the nut to guide the bolt's spiral movement, so that the bolt can tighten or loosen the clamping plate, making it convenient to control the bolt with the spiral.

[0019] 5. Use a knob to increase the operating lever length of the threaded rod. Manually turning the knob will rotate the threaded rod, making it convenient to manually operate the bolt.

[0020] 6. By using hemispherical blocks to connect with the extrusion plate, the stability of the stress point between the extrusion plate and the bolt is increased.

[0021] 7. After the threaded rod passes through the hemispherical block and presses against the groove, the mating seat acts on the tray, and the plate is locked at the lower part of the mold body, making it easy to lock the mold body on the tray. Attached Figure Description
