Description

Technical Field

[0001] This utility model relates to the field of stamping die technology, and more specifically to a stamping die. Background Technology

[0002] Stamping dies are special process equipment used in cold stamping to process materials into parts. Stamping is a pressure processing method in which pressure is applied to materials at room temperature using dies mounted on a press, causing them to separate or plastically deform, thereby obtaining the desired parts. During the stamping process, if the material is placed on the die and there is a horizontal offset, it will cause deviation in the stamping and the workpiece cannot be formed. Therefore, it is necessary to design a stamping die. Utility Model Content

[0003] In order to overcome the above-mentioned defects of the prior art, the present invention provides a stamping die to solve the problems existing in the background art.

[0004] This utility model provides the following technical solution: a stamping die, comprising a stamping die body, the stamping die body including two connecting seats, each connecting seat having a through hole for connecting to a press, a lower die and an upper die respectively located on the adjacent sides of the connecting seats, the connecting seats being connected to the lower die and the upper die respectively via connecting assemblies, guide assemblies on both sides of the top of the bottom connecting seats, each guide assembly including a fixing plate, the fixing plate being fixedly installed on both sides of the top of the bottom connecting seats, a lead screw being threaded onto the opposite side of the fixing plate, and a bearing being mounted on the adjacent ends of the lead screw. The mounting bases have an open design on their adjacent sides. Rollers are rotatably mounted on the adjacent sides of each mounting base via a rotating shaft. These rollers are located on the top of the lower die. Guide rods are fixedly mounted on the opposite sides of each mounting base, and these guide rods movably penetrate the fixed plate. Before stamping the sheet material, the sheet material is aligned between the two rollers and inserted, ensuring the bottom of the sheet material fits against the top of the lower die. The two rollers guide the sheet material as it moves, allowing it to completely cover the top of the lower die and preventing offset during stamping. Furthermore, the mounting bases and fixed plate are adjustable, facilitating adaptation to the width of the sheet material.

[0005] Furthermore, the number of fixing plates on each side is at least two, increasing the stability of the guide.

[0006] Furthermore, the rollers are all made of rubber, which can protect the edges and corners of the sheet-like raw materials and prevent wear.

[0007] Furthermore, the connecting assembly includes a fixing seat, which is fixedly installed on both sides of the two connecting seats that are close to each other. The upper and lower molds fit into the connecting seats. Bolts are movably installed through the outer side of the fixing seat. Threaded grooves that match the bolts are opened on both sides of the upper and lower molds. The lower and upper molds are detachably connected to the connecting seats. After the connecting seats are connected to the press, the lower and upper molds can be easily replaced.

[0008] Furthermore, each of the connecting seats has a limiting groove on its side that is close to the other, and each of the lower and upper molds has a limiting block that is adapted to the limiting groove fixedly installed at its side that is far from the other, so as to provide a limiting function.

[0009] Furthermore, the insertion end of the limiting block has a rounded chamfered corner design to facilitate alignment and insertion.

[0010] The technical effects and advantages of this utility model are as follows:

[0011] 1. This utility model adopts a design that allows the sheet material to be inserted between two rollers before stamping, so that the bottom of the sheet material and the top of the lower die are in contact. The two rollers guide the sheet material during its movement, allowing the sheet material to completely cover the top of the lower die and preventing it from shifting during stamping. In addition, the mounting base and the fixing plate adopt an adjustable design, which is convenient for adapting to the width of the sheet material.

[0012] 2. This utility model adopts this design to connect the connecting seat to the stamping end of the press and the worktable respectively. Since the lower die and the upper die are connected to the connecting seat through the connecting component, different shapes of lower dies and upper dies can be replaced and combined with the connecting seat after unscrewing the bolts, which simplifies the replacement process. The limiting blocks on the lower die and the upper die can be inserted into the limiting grooves to provide guidance and restriction, which facilitates connection. Attached Figure Description

Detailed Implementation

[0018] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0019] Example 1: Refer to Figure 1-4 This utility model provides a stamping die, including a stamping die body 100. The stamping die body 100 includes two connecting seats 110. The two connecting seats 110 are provided with through holes for connecting to a press. A lower die 111 and an upper die 112 are respectively provided on the side of the connecting seats 110 that are close to each other. The connecting seats 110 are connected to the lower die 111 and the upper die 112 through connecting components 300. Guide components 200 are provided on both sides of the top of the bottom connecting seat 110. The guide components 200 include a fixing plate 210, which is fixedly installed on the bottom connecting seat 110. On both sides of the top of the 0, the opposite sides of the fixing plates 210 are each fitted with a lead screw 211 via threads. The opposite ends of the lead screws 211 are each fitted with a mounting seat 212 via bearings. The opposite sides of the mounting seats 212 are each open-ended. The opposite sides of the mounting seats 212 are each fitted with a roller 213 via a rotating shaft. The roller 213 is located on the top of the lower mold 111. The opposite sides of the mounting seats 212 are each fitted with a guide rod 214. The guide rods 214 movably pass through the fixing plates 210. There are at least two fixing plates 210 on each side. The rollers 213 are all made of rubber.

[0020] The working principle of Embodiment 1 of this utility model is as follows: In use, the sheet material to be stamped is inserted between the two rollers 213. The rollers 213 and the sheet material roll and adhere to each other, so that the sheet material is stably located on the top of the lower die 111 between the two rollers 213. Then, driven by the hydraulic cylinder on the press, the upper die 112 stamps the sheet material into the lower die 111 to complete the stamping. By rotating the lead screw 211, the mounting base 212 and the rollers 213 move closer or further apart, which can be adjusted according to the width of the sheet material.

[0021] Example 2:

[0022] The difference between Embodiment 2 and Embodiment 1 is that: the connecting assembly 300 includes a fixing seat 310, which is fixedly installed on both sides of the two connecting seats 110 on the side closest to each other. The upper mold 112 and the lower mold 111 are fitted with the connecting seats 110. Bolts 311 are movably installed through the outer side of the fixing seat 310. Threaded grooves adapted to the bolts 311 are opened on both sides of the upper mold 112 and the lower mold 111. Limiting grooves 313 are opened on the side of the connecting seats 110 that are close to each other. The ends of the lower mold 111 and the upper mold 112 that are far apart from each other are fixedly installed with grooves corresponding to the limiting grooves. The limiting block 312, which is adapted to 313, has an arc-shaped chamfered corner at the insertion end. It connects the connecting seat 110 to the stamping end of the press and the worktable respectively. Since the lower die 111 and the upper die 112 are connected to the connecting seat 110 through the connecting assembly 300, the lower die 111 and the upper die 112 of different shapes can be replaced and combined with the connecting seat 110 after unscrewing the bolt 311, which simplifies the replacement process. The limiting block 312 on the lower die 111 and the upper die 112 are inserted into the limiting groove 313, which can provide guidance and restriction, and facilitate connection.
