Description

Technical Field

[0001] This utility model relates to the field of machining, specifically to a gasket stamping fixture. Background Technology

[0002] Stamping is a pressure processing method that uses dies mounted on stamping equipment (mainly presses) to apply pressure to materials, causing them to separate or undergo plastic deformation, thereby obtaining the desired parts (commonly known as stampings or stamped parts). Stamping is usually a cold deformation process of materials at room temperature, and it mainly uses sheet metal to process the required parts, so it is also called cold stamping or sheet metal stamping.

[0003] Washers are usually produced by stamping. Conventional sheet metal is fed through a chute. If the gap is small, the friction is large; if the gap is large, it may run off-center. Utility Model Content

[0010] The second base mold includes a base plate, on which a guide rod is slidably disposed, and the guide rod is connected to the pressure ring.

[0011] It also includes an elastic element, one end of which contacts the second base mold, and the other end of which contacts the pressure ring.

[0012] The elastic element is a spring.

[0013] The elastic element is a tower-shaped spring.

[0017] Figure 3 This is a cross-sectional schematic diagram of one embodiment of the present invention. Detailed Implementation

[0018] The present invention will be further described below with reference to the accompanying drawings: As shown in the figures, the gasket stamping fixture includes a bracket 1, which is provided with a fixedly mounted lower die assembly 2 and a liftable upper die assembly 3, and also includes a feeding bracket 4. The feeding bracket is provided with a feeding plate 41, and the feeding plate is provided with a U-shaped groove 42. The inner wall of the U-shaped groove is provided with a rotatable first roller 421. The lower die assembly includes a first base die 31 and a first core die 32. The first base die is provided with a positioning pin 311, and a second roller 312 is rotatably mounted on the positioning pin. The upper die assembly includes a second core die 22 and a second base die 21. The second base die includes a retractable pressure ring 210. The second core die is positioned opposite to the first core die for stamping the workpiece, and the pressure ring is positioned opposite to the first base die for pressing the workpiece. The pressure ring is provided with a receiving groove 211 positioned opposite to the positioning pin and the second roller. During stamping, the pressure ring presses down on the sheet metal 9 and then the core mold realizes the material feeding. This is existing technology and will not be elaborated further. The feature of this application is that the feeding support of the conveyor is equipped with a first roller and the lower mold is equipped with a second roller to realize stable feeding. That is, it can realize guidance without increasing friction. The first and second rollers can be realized by bearings. After the pressure ring is pressed down, the second roller and the positioning pin will fall into the receiving groove to avoid collision and will not affect the normal mold closing of the upper and lower molds.

[0019] In this embodiment, as shown in the figure, the second base mold includes a base plate 212, on which a slidably disposed guide rod 213 is provided. The guide rod is connected to the pressure ring. The guide rod can be a screw rod, which is clearance-fitted with the mounting groove of the base plate and threadedly connected to the mounting hole of the pressure ring.

[0020] In this embodiment, as shown in the figure, an elastic element 214 is also included. One end of the elastic element contacts the second base mold, and the other end contacts the pressure ring. It serves to elastically contract and reset.

[0021] In this embodiment, as shown in the figure, the elastic element is a spring.

[0022] In this embodiment, as shown in the figure, the elastic element is a tower-shaped spring.
