Description

A forging die

Technical Field

The utility model relates to the field of forging dies, in particular to a forging die.

Background technique

In the production process of elevator parts, some parts are made by forging, and in the forging process of these parts, forging dies are needed. Forging dies refer to a tool that can form a blank into a die forging. Forging dies are essential key process equipment in the production of die forgings. They are tools that need to be used in every stroke of the equipment and play a vital role in the production of die forgings.

When the forging die is used, for hot forging, the blank is heated and placed in the die, and the forging process is used to form the blank. When the existing hot forging die is used, there is no buffer structure on the lower die for placing the heated blank. During forging, the upper die directly contacts and hits the lower die. After long-term use of the die, the lower die and the upper die will be greatly worn, which is easy to cause damage to the die, thereby affecting the normal progress of subsequent forging. The cost of use is high, and during the forging process, the upper die and the blank need to collide. Compared with the lower die, the upper die is more prone to wear and tear, and the upper die needs to be replaced faster. The upper and lower dies cannot be replaced at the same time. It takes more time to replace the die multiple times, which is more complicated to operate and increases the cost of maintenance and replacement.

Detailed ways

In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

As shown in Figures 1 to 4, a forging die includes a lower die 2 and an upper die 7. The lower die 2 is installed on a base plate 1, and a cavity 3 is provided on the lower die 2. A buffer structure 4 is provided on the lower die 2. A die-casting component 8 is provided at the lower end of the upper die 7. A reset component 5 is provided on the base plate 1, and a lifting plate 6 is provided at the upper end of the reset component 5. A special-shaped hole 9 is provided on the lifting plate 6, and the special-shaped hole 9 is located directly above the upper cavity 3 of the lower die 2. A lifting rod 10 is fixed to the upper end of the upper die 7, and the upper die 7 is located directly above the lifting plate 6.

When using the forging die, the lower die 2 is fixed by the bottom plate 1, a buffer structure 4 is provided on the lower die 2, the upper die 7 is installed at the lower end of the lifting rod 10 in the forging machine, a die-casting assembly 8 is provided at the lower end of the upper die 7, and the lifting plate 6 is installed on the bottom plate 1 through the reset assembly 5. When hot forging is performed, the heated blank is placed in the special-shaped hole 9 and the cavity 3. After starting the forging machine, the driving mechanism brings the lifting rod 10 down, thereby causing the upper die 7 and the die-casting assembly 8 to descend. When the die-casting assembly 8 contacts the lifting plate 6, the lifting plate 6 descends together and compresses the spring in the reset assembly 5. When the lifting plate 6 contacts the buffer structure 4, the buffer structure 4 forms a buffer protection. To prevent the lifting plate 6 from directly hitting the lower die 2, as the forging work proceeds, the lifting plate 6 is limited after contacting the lower die 2. At this time, under the action of the die-casting component 8 and the lower die 2, the heated blank is formed in the cavity 3 and the special-shaped hole 9, thereby completing the forging work. After the forging is completed, the lifting rod 10 rises with the upper die 7 and the die-casting component 8. Under the action of the reset component 5, the lifting plate 6 rises with the forged parts and moves out of the cavity 3, and then the parts are removed. This process is repeated over and over again, and the forging work of the parts can be carried out continuously. With the use of the forging machine, the die-casting component 8 can be quickly disassembled and replaced after wear, thereby ensuring the normal progress of the subsequent forging work.

Through the above implementation scheme, the buffer structure 4 includes an annular groove 401, a buffer ring 402 and an elastic component 404, the annular groove 401 is opened on the lower mold 2, the buffer ring 402 and the elastic component 404 are arranged in the annular groove 401, the buffer structure 4 also includes a through hole 403, the through hole 403 starts on the buffer ring 402, and the lower end of the buffer ring 402 is located in the annular groove 401, the lower end of the buffer ring 402 is provided with a screw hole, the upper end of the elastic component 404 is connected to the buffer ring 402, and the lower end of the elastic component 404 abuts At the inner bottom end of the annular groove 401, the elastic components 404 are distributed in an annular array in the annular groove 401, and the elastic components 404 include a buffer spring 4041, a connecting block 4042, a stud 4043 and a pressing block 4044. The connecting block 4042 is connected to the upper end of the buffer spring 4041, and the connecting block 4042 is fixedly connected to the stud 4043. The stud 4043 is connected to the screw hole at the lower end of the buffer ring 402, and the pressing block 4044 is fixed to the lower end of the buffer spring 4041. The die-casting component includes a hexagonal block 4080. 1 and a pressing plate 803, the hexagonal block 801 is fixedly connected to the pressing plate 803, and the hexagonal block 801 is connected to the lower end of the upper die 7, the die-casting component 8 also includes a threaded joint 802, the hexagonal block 801 and the pressing plate 803 are integrally formed, the threaded joint 802 is fixed on the hexagonal block 801, and the threaded joint 802 is threadedly connected to the upper die 7, a buffer structure 4 is arranged on the lower die 2, during the forging process, as the lifting plate 6 descends, the buffer structure 4 can play a role of buffering protection, avoiding the lifting plate 6 from directly hitting the lower die 2, ensuring that the lower die 2 is less worn after long-term use, and reducing the use cost to a certain extent, a die-casting component 8 is arranged at the lower end of the upper die 7, and the die-casting component 8 is used to contact the blank for forging work, when the die-casting component 8 is worn, it can be directly disassembled and replaced, without the need to disassemble and replace the entire upper die 7, reducing the replacement cost, so that the upper die 7 can be used for a long time, and together with the lower die 2, it is ensured that the upper die 7 and the lower die 2 can be replaced at one time after long-term use, without the need to replace them separately, further reducing the replacement cost.

When installing the buffer structure 4, the stud 4043 on the connecting block 4042 is screwed into the screw hole on the buffer ring 402, so that the elastic component 404 is connected to the buffer ring 402, and then the elastic component 404 is set in the annular groove 401, so that the tightening block 4044 at the lower end of the buffer spring 4041 contacts the bottom end of the annular groove 401, and the lower end of the buffer ring 402 is located in the annular groove 401. During the forging process, after the lifting plate 6 contacts the buffer ring 402, the buffer ring 402 is forced to move downward, thereby compressing the buffer spring 4041. The buffer spring 4041 shortens the stroke buffering to prevent the lifting plate 6 from directly hitting the lower die 2, thereby ensuring the integrity of the lower die 2. As the forging work proceeds, the pressure plate 803 in the die-casting component 8 is in contact with the parts for a long time and wear occurs. At this time, the hexagonal block 801 can be clamped with a tool to remove the threaded joint 802 from the upper die 7, and then the die-casting component 8 can be replaced and continued to be used after replacement.
