Description

A cold stamping die with flanging mechanism

technical field

The utility model relates to a cold stamping die, in particular to a cold stamping die with a flanging mechanism.

Background technique

Some cold stamping products involve the process of compound flanging. In the mold structure of traditional products, the compound flanging process is generally completed by double floating mechanism or divided into two sequences. The double floating mechanism has a high mold closing height, which causes the mold to equipment There are certain requirements for the closed height. In actual production, due to the problem of closing height, it is common to choose a larger tonnage, and the double floating mechanism has problems such as high manufacturing cost, long cycle, and short life. Divided into two processes to complete, although the mold structure is simple, the production cost is high, and the product stability is not easy to control.

Utility model content

The purpose of this utility model is to provide a cold stamping die with a flanging mechanism, which can effectively solve the problem that when the workpiece needs composite flanging, it needs to add a process or use a mold with a double Fudong mechanism, so that the production cost is increased and the product stability is not easy to control. The problem.

In order to solve the above technical problems, the utility model is achieved through the following technical solutions: a cold stamping die with a flanging mechanism, including an upper die, a lower die, and a flanging mechanism, and the flanging mechanism includes a lever, a support block, Press block, the support block has two pieces, the support block is arranged on the upper plane of the lower mold, the middle part of the lever is pierced with a rotating shaft, the rotating shaft is arranged between the two support blocks, and the pressing block is arranged on the upper plane The lower plane of the mold.

Preferably, an elastic return device is provided between the right end of the lever and the lower mold, and the pressing block is arranged on the upper module above the right end of the lever; it is convenient for the return of the lever.

Preferably, the lower mold below the lever is also provided with a spacer, the right end of the spacer is provided with a placement hole, and the lower end of the elastic return device is arranged in the placement hole; it can be adjusted for molds of different heights, so that The leverage will not be too high.

Preferably, the elastic return device is a compression spring; an elastic return device with simple structure, reliable performance and affordable price.

Preferably, the lower die is provided with a guide rod, and the upper die is provided with a guide hole matching the guide rod; so that the upper die and the lower die can be accurately aligned.

Compared with the prior art, the utility model has the advantages of: when the upper mold and the lower mold are pressed together, the workpiece is flanged simultaneously by using the principle of leverage, which reduces the closing height of the mold, increases the selectivity of the equipment, and simplifies the compounding process. The mold mechanism makes the mold simpler and more stable, and also reduces the mold manufacturing cost.

Detailed ways

Referring to Fig. 1, it is an embodiment of a cold stamping die with a flanging mechanism of the utility model, a cold stamping die with a flanging mechanism, comprising an upper die 1, a lower die 2, and a flanging mechanism, and the flanging mechanism Including a lever 3, a support block 4, and a pressure block 5, the support block 4 has two pieces, the support block 4 is arranged on the upper plane of the lower mold 2, and the middle part of the lever 3 is pierced with a rotating shaft 6, and the rotating shaft 6 is set Between the two support blocks 4, the briquetting block 5 is arranged on the lower plane of the upper mold 1, and an elastic return device 7 is arranged between the right end of the lever 3 and the lower mold 2, and the briquetting block 5 is arranged on the lever 3 On the upper mold 1 above the right end, the lower mold 2 below the lever 3 is also provided with a spacer 8, the right end of the spacer 8 has a placement hole, and the lower end of the elastic return device 7 is arranged on Placed in the hole, the elastic return device 7 is a compression spring, the lower die 2 is provided with a guide rod 9 , and the upper die 1 is provided with a guide hole 10 matched with the guide rod 9 .

As shown in Figure 2, when the upper mold 1 and the lower mold 2 are not pressed together, the left end of the lever 3 of the flanging mechanism is drooping, and the right end of the lever 3 is upturned; as shown in Figure 3, when the upper mold 1 and the lower mold 2 are pressed together , the pressure block 5 arranged on the upper mold 1 presses down the right end of the lever 3, so that the left end of the lever 3 is put on the stage, and the workpiece is flanged; after the upper mold 1 and the lower mold 2 are separated, due to the elastic return device 7 Effect, make the right end of lever 3 go on stage again, and the left end of lever 3 is drooping.

When the upper mold 1 and the lower mold 2 are pressed together, the principle of lever 3 is used to flang the workpiece at the same time, which reduces the closing height of the mold, increases the selectivity of equipment, simplifies the structure of the composite mold, and makes the mold simpler and more stable. Also reduces mold manufacturing cost.

The above is only a specific embodiment of the utility model, but the technical characteristics of the utility model are not limited thereto, and any changes or modifications made by those skilled in the art within the scope of the utility model are all covered by the utility model. In the scope of the new patent.
