Description

Technical Field

[0001] This utility model relates to the field of fine blanking compound die technology, and specifically to a waste material detection mechanism for fine blanking compound dies. Background Technology

[0002] Fine blanking compound dies are dies that combine precision blanking with multiple forming processes. They are widely used in various fields, offering high production accuracy and efficiency, and meeting the demand for high-precision, high-quality products in various industries. However, the waste generated during the production of fine blanking compound dies can easily accumulate, affecting equipment operation and requiring waste detection. Existing waste detection methods for fine blanking compound dies have low efficiency, failing to protect the equipment in a timely manner and reducing the safety performance of the dies. Utility Model Content

[0003] To address the shortcomings of existing fine blanking compound dies, such as low scrap detection efficiency, inability to protect equipment in a timely manner, and reduced die safety, this utility model provides a scrap detection mechanism for fine blanking compound dies. This mechanism has high detection efficiency, can protect equipment in a timely manner, and increases die safety.

[0004] This utility model provides the following technical solution:

[0005] It includes an upper die base and a lower die base. The upper die base is slidably connected to the lower die base via guide pillars and guide sleeves. A blanking structure is provided between the upper die base and the lower die base, located below the blanking structure. A scrap detection structure is provided inside the lower die base. The scrap detection structure includes a movable scrap channel, an air blowing fixture, and a detection fixture. The movable scrap channel is installed on the lower die base. Air blowing fixtures and detection fixtures are respectively provided on both sides of the movable scrap channel. Both the air blowing fixture and the detection fixture are installed on the lower die base. An air blowing connector is installed on the upper part of the air blowing fixture, and an air blowing copper pipe installed on its lower part is inserted into the movable scrap channel. A detector installed at the end of the detection fixture maintains inductive contact with the movable scrap channel.

[0006] Its further features are:

[0007] The blanking structure includes a punch, a die, a punch backing plate, a punch fixing plate, and a die fixing plate. The punch backing plate is bolted to the upper die base, and the punch fixing plate is mounted on the punch backing plate. A stripper backing plate and a stripper plate are provided below the punch fixing plate. The stripper backing plate and the stripper plate are bolted together to form a stripper assembly. The stripper assembly is bolted to the punch fixing plate. One end of the punch is mounted on the punch fixing plate, and the other end passes through the stripper assembly. A die backing plate and a die fixing plate are provided above the lower die base. The die backing plate and the die fixing plate are sequentially pressed onto the lower die base. The die is mounted on the die fixing plate. A scrap channel is provided below the die, and the scrap channel passes through the die backing plate, the die fixing plate, and the movable scrap channel.

[0008] The unloading plate and the die fixing plate are connected by a guide member;

[0009] A load-bearing plate is installed inside the unloading back plate, and the end of the load-bearing plate is in close contact with the unloading plate;

[0010] A waste material breaking and fixing block is provided at the connection between the waste material channel and the movable waste material channel.

[0011] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0012] The waste detection structure is designed with a detector and a moving waste channel that fit closely together. Waste accumulates and blocks in the moving waste channel. The accumulated waste increases the weight of the moving waste channel, causing it to lose contact with the detector. When there is a distance between the detector and the moving waste channel, a signal is immediately generated to stop the entire device from operating. It has high detection efficiency, can interrupt the operation of the device in time to protect the device, and increases the safety performance of the mold.

[0013] The design of the waste material breaking and fixing block facilitates the separate discharge of waste material, reduces the possibility of waste material blockage, and further increases the safety performance of the mold. Attached Figure Description

[0017] This utility model provides, for example Figure 1 The scrap detection mechanism of the fine blanking compound die shown includes an upper die base 1 and a lower die base 2. The upper die base 1 is slidably connected to the lower die base 2 through guide pillars and guide sleeves. A blanking structure is set between the upper die base 1 and the lower die base 2, located below the blanking structure. A scrap detection structure is set inside the lower die base 2. The scrap detection structure includes a movable scrap channel 3, an air blowing fixed seat 5, and a detection fixed seat 8. The movable scrap channel 3 is installed on the lower die base 2. Air blowing fixed seats 5 and detection fixed seats 8 are respectively set on both sides of the movable scrap channel 3. Both air blowing fixed seats 5 and detection fixed seats 8 are installed on the lower die base 2. An air blowing connector 6 is installed on the upper part of the air blowing fixed seat 5, and an air blowing copper pipe 7 installed on its lower part is inserted into the movable scrap channel 3. A detector 9 installed at the end of the detection fixed seat 8 maintains inductive contact with the movable scrap channel 3. When the detector 9 is separated from the movable scrap channel 3, a command signal is generated to stop the entire die from working.

[0018] The blanking structure includes a punch 15, a die 16, a punch backing plate 10, a punch fixing plate 11, and a die fixing plate 17. The punch backing plate 10 is bolted to the upper die base 1, and the punch fixing plate 11 is mounted on the punch backing plate 10. A stripper backing plate 12 and a stripper plate 18 are provided below the punch fixing plate 11. The stripper backing plate 12 and the stripper plate 18 are bolted together to form a stripper assembly. The stripper assembly is bolted to the punch fixing plate 11. One end of the punch 15 is mounted on the punch fixing plate 11, and the other end passes through the stripper assembly. A die backing plate and a die fixing plate 17 are provided above the lower die base 2. The die backing plate and the die fixing plate 17 are sequentially pressed onto the lower die base 2. The die 16 is mounted on the die fixing plate 17. A scrap channel is provided below the die 16. The scrap channel passes through the die backing plate, the die fixing plate 17, and the movable scrap channel 3.

[0019] The stripper plate 18 and the die fixing plate 17 are connected by a guide member 14;

[0020] A load-bearing plate 13 is installed inside the unloading back plate 12. The end of the load-bearing plate 13 is tightly fitted with the unloading plate 18. The load-bearing plate 13 is used to increase the connection stability between the unloading back plate 12 and the unloading plate 18.

[0021] Waste material separating and fixing block 4 is provided at the connection between the waste material channel and the moving waste material channel 3. The waste material separating and fixing block 4 is used to separate the waste material to facilitate waste material discharge.

[0022] Working principle of this utility model:

[0023] Refer to the instruction manual appendix Figure 1When using this utility model, the waste material generated after the punch 15 enters the die 16 for punching will pass through the waste material channel and then be split open by the waste material splitting block 4 and enter the movable waste material channel 3. If the waste material is blocked in the movable waste material channel 3, the movable waste material channel 3 in contact with the detector 9 will move downward. After the detector 9 detects the distance between itself and the movable waste material channel 3, it will understand that a signal command is issued to stop the entire equipment from running. The detection efficiency is high and the protection of the mold is strong.
