How to design a robotic stamping mold

2025-06-23

Stamping mold is a very important part of the robot manufacturing, this paper will be a comprehensive introduction and discussion of its design.

I. Design process and key points

1. Understanding of the robot and stamping process: In the design of stamping molds before the need for the robot's operating principle, the ability to move as well as the stamping process has a comprehensive understanding and mastery. This includes factors such as raw material feed, product drop, burrs, removal of wear parts, molds have / weight and size, hardness and strength, hazardous area protection, hydraulic presses and punching machine operation safety.

2. Determine the die structure: Based on the robot's motion capabilities and the stamping process, determine the structure and size of the die. This includes the structure and length of the punch is critical in the mold, round punch is divided into first-order, second-order and third-order, there are two forms of A-punch and T-punch, you can choose to use according to the thickness of the material and the diameter of the hole, there is a protective cover structure to improve the longitudinal resistance to bending.

3. Design of mold parts: According to the structure of the mold, design the mold parts, including convex die, concave die, fixed plate, unloading plate and so on. It should be noted that the length of the punch is generally determined by the die structure, which can be calculated according to the formula, but needs to be modified according to the die structure and requirements.

4. Design of die material: According to the requirements of stamping process and die parts, choose the suitable die material. Factors to be considered include the hardness and strength of the material, abrasion resistance, corrosion resistance and so on.

5. Designing the mold structure: According to the design of the mold parts, design the overall structure of the mold, including the shape of the mold, the installation method, the positioning method and so on.

6. Design the safety protection of the mold: when designing the mold, the safety of the robot needs to be taken into consideration, including the guards of the mold, safety switches and so on.

II. Design Example

Take a simple robot stamping mold as an example to introduce its design process and key points.

1. Determine the structure of the mold: the mold is a simple stamping mold for stamping a round part. The structure of the mold includes convex die, concave die, fixed plate, unloading plate and so on.

2. Design the mold parts: the convex and concave dies are of circular shape, the diameter of the convex die is the diameter of the part, the diameter of the concave die is 0.5mm larger than the convex die, the fixed plate and the unloading plate are of rectangular shape, the size of the fixed plate is 100mm×100mm, the size of the unloading plate is 100mm×50mm. 3. Design the mold material: the convex die is a simple stamping mold for stamping a round part.

3. Designed mold materials: No.45 steel is used for the convex and concave molds, and No.45 steel is used for the fixed plate and the unloading plate.

4. Designing the mold structure: the overall structure of the mold is rectangular, with dimensions of 100mm×100mm×100mm, the mold is installed on the robot's working table, and the positioning is done by the positioning pins of the convex and concave molds.

5. Design the safety protection of the mold: the safety protection of the mold includes the safety switches of the convex and concave molds, and the protective cover of the mold.

The design of the robot stamping die needs to take into account the robot's motion ability, stamping process, die structure, die parts, die materials, die structure, safety protection of the die and other factors. In the design process, it is necessary to carry out continuous optimization and improvement according to the actual situation in order to improve the performance and quality of the die.
