Description

A kind of stamping mold with adjustable mold cavity

Technical field

The invention belongs to the field of stamping technology, and is specifically a stamping die with an adjustable mold cavity.

Background technique

Stamping die is a special process equipment used to process metal or non-metal materials into parts or semi-finished products in cold stamping processing. It is called cold stamping die (commonly known as cold stamping die). Stamping is installed on the press at room temperature. A pressure processing method in which the mold exerts pressure on the material to cause separation or plastic deformation to obtain the desired parts.

Generally, stamping dies are divided into two categories. One is process parts. These parts are directly involved in the completion of the process and have direct contact with the blank. They only complete the process of the mold and do not directly participate in the completion of the process, nor are they directly in contact with the blank. Contact only guarantees the completion of the mold process or improves the function of the mold, including guide parts, fastening parts, standard parts and other parts.

As far as the stamping of auto parts is concerned, cold stamping is usually used to process the steel plate material into a specified shape. However, when the existing mold is used, because the space in the mold cavity is fixed, the steel plate material is processed into different shapes. , it is necessary to replace different molds, which reduces the practicality of the mold.

The rotation of the threaded sleeve 15 is used to drive the movement of the threaded rod 125 .

Working principle: When in use, the steel plate material to be punched that meets the specifications is placed into the lower mold assembly 11. Under the support of the support block 115, the steel plate material to be punched will be supported on the inside of the lower mold 111, and then the servo motor 3 is started. The output end of the servo motor 3 drives the threaded rod 4 to rotate clockwise, which in turn drives the sliding plate 6 to move. Since the sliding plate 6 is embedded in the inside of the chute 7, the clockwise rotation of the threaded rod 4 at this moment will drive the threaded sleeve 5 Move downward, and then drive the sliding plate 6 to move downward along the chute 7. Under the connection of the connecting rod 8, the connecting rod 8 will push the upper mold assembly 9 to move downward, and then push the upper mold 92 into the inside of the lower mold 111. , under the extrusion force of the upper die 92, the steel plate material is processed into a model that fits the second die 124, thereby completing the stamping of the steel plate material;

During the stamping process, the support block 115 will be squeezed and enter the groove 114;

After the stamping is completed, the servo motor 3 is driven again, so that the output end of the servo motor 3 drives the threaded rod 4 to rotate counterclockwise, thereby driving the sliding plate 6 to move upward, and under the connection of the connecting rod 8, the upper mold assembly 9 is driven to move upward. , so that the upper mold assembly 9 and the lower mold assembly 11 are separated, and then the stamped steel plate material is removed;

When the steel plate material needs to be processed into another standard shape, the staff manually rotates the handle 16 clockwise, so that the handle 16 drives the threaded sleeve 15 to rotate. Under the action of the threaded connection between the threaded sleeve 15 and the threaded rod 125, the thread The rotation of the second sleeve 15 will drive the threaded rod 125 to move. Since the limit block 13 is located in the limit groove 122, the limit rod 121 is slidingly connected to the limit hole 14. At this moment, the rotation of the threaded sleeve 15 will drive the threaded rod 2 125. Gradually pass through the threaded sleeve 2 15. At this moment, the threaded rod 2 125 will drive the mold 2 124 to pass through the through hole 112, thereby causing the mold 2 124 to detach from the lower mold 111, and at the same time drive the mold 1 123 to pass through the through hole 112 and enter the mold groove. 113, when the mold one 123 completely enters the mold groove 113, just stop turning the handle 16, and then replace the upper mold 92.
