Description

Technical Field

[0001] The utility model relates to the technical field of stamping dies, in particular to a supporting mechanism and a stamping die thereof. Background Art

[0002] A stamping die is a tool used to stamp metal sheets or strips into required shapes. It is an indispensable part of stamping forming technology and is widely used in industries such as automobiles, electronics, and household appliances. In order to ensure the normal operation of the die and extend its service life, some usage and maintenance techniques need to be noted.

[0003] When the stamping die is in production, the pressure is relatively large. The vibration reduction measures of the stamping die generally include optimizing the structure of the die, increasing the stiffness of the die, and reasonably selecting the stamping die material, etc. However, the above vibration reduction methods are mostly for the vibration reduction of the material strength of the die itself and are difficult to reduce the reaction force of the support on the die. Therefore, a supporting mechanism and a stamping die thereof are needed. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a supporting mechanism and a stamping die thereof to solve the problems raised in the above background art: The vibration reduction measures of the stamping die generally include optimizing the structure of the die, increasing the stiffness of the die, and reasonably selecting the stamping die material, etc. However, the above vibration reduction methods are mostly for the vibration reduction of the material strength of the die itself and are difficult to reduce the reaction force of the support on the die.

[0005] To achieve the above purpose, the utility model provides the following technical scheme: A supporting mechanism includes a supporting bottom plate. At the center of the upper surface of the supporting bottom plate, two mounting cross plates are fixedly connected. An electric cylinder is installed between the tops of the two mounting cross plates. A stamping die seat is fixedly installed between the two mounting cross plates. The output end of the electric cylinder is fixedly connected to a stamping upper die. Four buffer components are connected to the upper surface of the supporting bottom plate near the stamping die seat. One end of each buffer component is fixedly connected to two mounting connecting plates. Each mounting connecting plate and the outer side of the stamping upper die are threadedly connected by fastening bolts. Four positioning components are fixedly connected to the edge of the lower surface of the supporting bottom plate. The purpose of such a setting is: By setting the buffer components, when the stamping upper die falls and approaches the bottom of the stamping die seat, buffering can be carried out to avoid excessive pressure on the stamping upper die under the push of the electric cylinder, resulting in excessive reaction force of the stamping die seat on the supporting bottom plate. By setting the positioning components, the supporting bottom plate can be positioned on the processing platform.

[0006] Preferably, the buffer component includes a limit sleeve housing, and a polyurethane spring is installed inside the limit sleeve housing.

[0007] Preferably, a buffer guide rod is inserted into the center of the polyurethane spring, and a buffer connecting plate is sleeved on the outer side of the buffer guide rod.

[0008] Preferably, one end of the upper surface and one end of the lower surface of the buffer connecting plate are both fixedly connected to the mounting connecting plate.

[0009] Preferably, the positioning assembly includes a positioning screw, and a positioning nut is threadedly connected to the outer surface of the positioning screw. The purpose of such a setting is that when the upper stamping die moves downward, it drives the buffer connecting plate to move downward. The buffer connecting plate moves downward under the guidance of the buffer guide rod. The buffer connecting plate squeezes the polyurethane spring. Through the polyurethane spring, the buffer connecting plate and the upper stamping die can be buffered, reducing the reaction force of the stamping die base on the support bottom plate, and solving the problem that the vibration reduction measures of the stamping die generally optimize the structure of the die, increase the stiffness of the die, and reasonably select the stamping die material, etc. And the above vibration reduction methods are mostly the vibration reduction of the material strength of the die itself, and it is difficult to reduce the reaction force of the support on the die.

[0010] Another object of the present invention is to provide a stamping die, and the stamping die includes the support mechanism as described above.

[0012] (1) The device of the present invention can buffer the upper stamping die when it falls close to the bottom of the stamping die base through the buffer assembly provided, avoiding excessive pressure on the upper stamping die under the push of the electric cylinder, resulting in excessive reaction force of the stamping die base on the support bottom plate. When the upper stamping die moves downward, it drives the buffer connecting plate to move downward. The buffer connecting plate moves downward under the guidance of the buffer guide rod. The buffer connecting plate squeezes the polyurethane spring. Through the polyurethane spring, the buffer connecting plate and the upper stamping die can be buffered, reducing the reaction force of the stamping die base on the support bottom plate, and solving the problem that the vibration reduction measures of the stamping die generally optimize the structure of the die, increase the stiffness of the die, and reasonably select the stamping die material, etc. And the above vibration reduction methods are mostly the vibration reduction of the material strength of the die itself, and it is difficult to reduce the reaction force of the support on the die.
