Description

Technical Field

[0001] The utility model belongs to the technical field of punching die structure improvement, and particularly relates to a punching die structure. Background Art

[0002] In today's industrial production environment, punching dies are key components in the stamping process, and their performance and structure are directly related to production efficiency and product quality. However, with the acceleration of industrialization and the annual increase in the company's stamping part output, the structure and performance of traditional punching dies have gradually exposed some problems, especially in their application in automated stamping production.

[0003] Currently, many companies still rely on traditional punching dies, most of which lack stripper plates. In manual operation, workers manually place parts on the die before punching. However, with the introduction of automated production lines and the increase in stamping part production, the drawbacks of these traditional dies are becoming increasingly apparent.

[0004] Without a stripper, parts can easily tilt during placement due to improper handling or uneven mold surfaces. This not only affects punching accuracy but also increases the difficulty and risk of manually retrieving parts. Workers must exercise extreme caution to prevent parts from slipping and causing injury. Robots are widely used in automated production lines to grasp and place parts. However, when punching dies lack a stripper, the punched part wraps tightly around the die, making it difficult for the robot to accurately grasp it. This not only reduces production efficiency but can also damage the robot or cause part deformation.

[0005] In order to solve the above problems, some mold manufacturers have added a stripper plate structure to the punching mold, such as Figure 1 As shown in the figure, this improvement does improve the stability of part placement and the efficiency of unloading after punching. However, due to the flared shape of the lower port of the part, the robot still easily slips when grasping the part, which not only affects the continuity and stability of automated production, but also may cause production line downtime and increased maintenance costs. Summary of the Invention

[0006] The purpose of the utility model is to overcome the above problems and provide a punching die structure, which can eliminate the problems of skewness and slippage when the original punching die robot clamps parts, and realize the reliability and stability of the punching die in picking up parts.

[0007] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0008] The utility model provides a punching die structure, comprising a punching die, a stripper plate is provided on the punching die, a boss is provided above the stripper plate, a part is provided on the punching die, a lower port of the part is located above the boss, and an outer diameter of the boss is 0.5mm to 1mm smaller than an outer diameter of the part.

[0009] A further improvement of the present invention is that the punching die is arranged on a punching die fixing plate.

[0010] A further improvement of the present invention is that a plurality of unloading screws are fixedly provided on the punching die fixing plate.

[0011] A further improvement of the present invention is that a discharge spring is sleeved on the outside of the discharge screw.

[0012] A further improvement of the present invention is that the discharge plate is connected to the punching die fixing plate via a discharge screw.

[0013] A further improvement of the present invention is that a plurality of threaded holes are evenly arranged on the discharge plate.

[0014] A further improvement of the present invention is that the unloading screw is connected to the unloading plate through a threaded hole.

[0015] A further improvement of the present invention is that the number of the unloading screws is the same as the number of the threaded holes.

[0016] A further improvement of the present invention is that the number of the unloading screw and the number of the threaded holes are both 3.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] The utility model provides a punching die structure. By providing a stripper plate on the punching die, the problem of parts being easily skewed when placed directly on the punching die is effectively solved. The stripper plate provides a flat and stable support surface, ensuring the accuracy of the part's position during the punching process. In addition, a boss is added to the stripper plate, and the outer diameter of the boss is 0.5mm to 1mm smaller than the outer diameter of the part, allowing the manipulator to more firmly grip the outer diameter of the part. The boss design provides a clear gripping point for the manipulator, preventing the manipulator from easily slipping when gripping the part due to the presence of a bell mouth at the lower end of the part. This ensures the reliability and stability of the manipulator in gripping the part, reduces downtime caused by part slippage or unstable gripping, and improves production efficiency.

[0019] Furthermore, a discharge spring is sheathed around the outer surface of the discharge screw. During the punching process, the part presses down on the discharge plate, compressing the discharge spring. Once the punching is complete, the discharge spring immediately releases its stored energy, pushing the discharge plate upward, thereby smoothly discharging the part from the outer cylindrical surface of the punching die. This automatic discharge mechanism greatly simplifies the operation process and improves production efficiency. The discharge spring acts as a buffer during the compression process, reducing the direct impact of the part on the punching die and the discharge plate, which helps reduce the risk of mold wear and damage and extend the mold's service life. At the same time, the discharge spring's buffering effect also protects the part from deformation or damage caused by the excessive impact force generated by punching.

[0032] The present invention is described in further detail below with reference to the accompanying drawings:

[0033] like Figure 2As shown, an embodiment of the utility model provides a punching die structure, including a punching die 1, a stripping plate 2, a boss 3, a punching die fixing plate 4, a part 5, a stripping screw 6 and a stripping spring 7, wherein a stripping plate 2 is provided on the punching die 1. The setting of the stripping plate 2 effectively solves the problem that the part 5 is easily skewed when placed directly on the punching die 1. The stripping plate 2 provides a flat and stable supporting surface, ensuring the position accuracy of the part 5 during the punching process.

[0034] In this application, a boss 3 is provided above the unloading plate 2, a part 5 is provided on the punching die 1, the lower end of the part 5 is located above the boss 3, and the outer diameter of the boss 3 is 0.5mm~1mm smaller than the outer diameter of the part 5.

[0035] In the present application, the punching die 1 is arranged on the punching die fixing plate 4, which can ensure that the punching die 1 does not move or shake during operation, effectively prevent the punching die 1 from being displaced or tilted during use, ensure the high precision of the punching operation, and meet the strict requirements of the workpiece on hole position accuracy and dimensional accuracy.

[0036] In this application, a plurality of discharge screws 6 are fixedly mounted on the punching die fixed plate 4, and a discharge spring 7 is sleeved on the outside of the discharge screw 6. During the punching process, the part 5 presses the discharge plate 2 downward, causing the discharge spring 7 to be compressed. Once the punching is completed, the discharge spring 7 immediately releases its stored energy, pushing the discharge plate 2 upward, thereby smoothly discharging the part 5 from the outer cylindrical surface of the punching die 1. This automatic unloading mechanism greatly simplifies the operation process and improves production efficiency. The discharge spring 7 acts as a buffer during the compression process, reducing the direct impact of the part 5 on the punching die 1 and the discharge plate 2, which helps reduce the risk of wear and damage to the die and prolong the service life of the die. At the same time, the buffering effect of the discharge spring 7 can also protect the part 5 from deformation or damage caused by the excessive impact force generated by the punching.

[0037] like Figure 3 and Figure 4 As shown, in the present application, a number of threaded holes 8 are evenly arranged on the unloading plate 2, and a through hole is provided on the punching die fixing plate 4. One end of the unloading screw 6 passes through the through hole on the punching die fixing plate 4, and the other end of the unloading screw 6 passes through the threaded hole 8 and is connected to the unloading plate 2. The number of unloading screws 6 is the same as the number of threaded holes 8. The unloading screw 6 is tightly connected to the unloading plate 2 through the threaded hole 8. This connection method has high strength and stability, can withstand large impact force and vibration, and ensures that the mold will not loosen or deform during the punching operation; in addition, the threaded holes are evenly arranged on the unloading plate 2 so that the unloading screws 6 can be evenly distributed, further enhancing the overall stability and working precision of the mold.

[0038] In the embodiment of the present application, there are three unloading screws 6 and three threaded holes 8, forming a three-point support to ensure that the unloading plate 2 can evenly distribute the force when under pressure, preventing deformation or damage caused by excessive force at a single point.

[0039] In the embodiment of the present application, the stripper plate 2 is made of No. 45 steel. No. 45 steel has high strength and good toughness, so that the stripper plate 2 can withstand large punching pressure and vibration. Moreover, after heat treatment, the wear resistance of No. 45 steel is significantly improved, which enables the stripper plate 2 to maintain good surface finish and dimensional accuracy during long-term punching operations, thereby extending the service life of the mold.

[0040] In the embodiment of the present application, the outer diameter of the boss 3 is 0.5 mm smaller than the outer diameter of the part 5, so that the manipulator can be more stable when clamping the outer circle of the part 5. The design of the boss 3 provides a clear clamping point for the manipulator, avoiding the manipulator from slipping when clamping the part 5 due to the presence of a bell-shaped mouth at the lower end of the part 5, ensuring the reliability and stability of the manipulator in clamping the part 5, reducing the downtime caused by the part 5 slipping or unstable clamping, and improving production efficiency.

[0041] Working principle:

[0042] The punching die 1 is mounted on the die fixing plate 4. The stripper plate 2 is connected to the die fixing plate 4 via a stripper screw 6, forming a stable support structure. The stripper screw 6 passes through a hole in the die fixing plate 4 and tightly connects with a threaded hole 8 in the stripper plate 2, ensuring the overall stability of the die. A boss 3 is positioned above the stripper plate 2. The outer diameter of the boss 3 is 0.5mm to 1mm smaller than that of the part 5, providing a clear gripping point for the robot. Part 5 is placed above the boss 3. Due to the design of the boss 3, the lower end of part 5 is located above the boss 3, ensuring accurate positioning of the part during the punching process. The robot grips the outer diameter of part 5 and securely places it on the boss 3, preventing it from slipping due to the flared lower end of part 5.

[0043] During the punching process, part 5 presses downward on stripper plate 2, compressing stripper spring 7. This compression acts as a buffer, mitigating the direct impact of part 5 on the punching die 1 and stripper plate 2. Once punching is complete, the punch returns, and stripper spring 7 immediately releases its stored energy, pushing stripper plate 2 upward. This upward motion of stripper plate 2 smoothly removes part 5 from the outer cylindrical surface of the punching die 1, achieving automatic unloading. After extended punching operations, stripper plate 2 may require maintenance or replacement due to wear. In this case, the stripper screw 6 can be loosened and stripper plate 2 can be removed from the die for inspection or replacement.
