Description

Technical Field

[0001] This utility model relates to the field of automotive parts processing mold technology, and in particular to a bending mold for automotive parts processing. Background Technology

[0002] In the processing of automotive parts, bending dies are often used for bending. Existing bending dies generally do not have a limiting structure, making it difficult to calibrate the position when processing parts of different sizes, resulting in large dimensional deviations.

[0003] The prior art CN220497400U discloses a bending die for automotive parts, including a base, a bending die, an L-shaped plate, an upper bending assembly, a distance control plate, and an adjustment assembly. The bending die is fixedly connected to the top of the base and has a bending groove. The L-shaped plate is fixedly connected to the top of the base. The upper bending assembly is disposed on the L-shaped plate, with its output end aligned with the bending groove. The distance control plate is slidably connected between the L-shaped plate and the lower bending die. The adjustment assembly is disposed on the L-shaped plate. When using the die, the adjustment assembly is activated according to the size of the part being processed to adjust the position of the distance control plate, thereby controlling the distance between the distance control plate and the bending groove. This allows the die to limit the movement of parts of different sizes. After the distance is appropriate, the part is placed on the bending die and pressed against the distance control plate. Then, the upper bending assembly is activated to bend the part, thus achieving the effect of limiting the movement of parts of different sizes and improving processing accuracy.

[0004] However, the existing automotive component bending dies cannot be replaced, and can only be bent at one angle. When bending at other angles, different dies are required, making it difficult to meet the bending requirements of different components. Utility Model Content

[0005] The purpose of this utility model is to provide a bending die for processing automotive parts, which aims to solve the problem that existing automotive part bending dies cannot be replaced and can only be bent at one angle. When bending at other angles, a different die is required, which makes it difficult to meet the bending requirements of different parts.

[0006] To achieve the above objectives, this utility model provides a bending die for processing automotive parts, including a base, an L-shaped plate, and a die replacement mechanism. The die replacement mechanism includes a bending assembly, a stamping die, a bending die, a fixing plate, multiple fixing bolts, and a reinforcing assembly. The L-shaped plate is fixedly connected to the top of the base. The base has a replacement groove and multiple fixing holes. The bending assembly is disposed on the L-shaped plate. The stamping die is disposed below the bending assembly. The bending die is slidably connected to the base and located within the replacement groove. The fixing plate is fixedly connected to the bottom of the bending die and has multiple replacement holes that respectively mate with the multiple fixing holes. The multiple fixing bolts are threadedly connected to the base and pass through the multiple replacement holes, and are respectively located within the multiple fixing holes. The reinforcing assembly is disposed on the L-shaped plate.

[0007] The bending assembly includes a cylinder, a stamping shaft, a connector, and a stabilizer. The cylinder is fixedly connected to the top of the L-shaped plate, the stamping shaft is fixedly connected to the output end of the cylinder and passes through the L-shaped plate, the connector is disposed between the stamping shaft and the stamping die, and the stabilizer is disposed on the L-shaped plate.

[0008] The connector includes a mounting frame, a connecting block, and multiple mounting bolts. The mounting frame is fixedly connected to the lower part of the stamping shaft. The connecting block is fixedly connected to the stamping die and slidably connected within the mounting frame.

[0009] The stabilizer also includes two stabilizing frames and two stabilizing rods. The two stabilizing frames are fixedly connected to the top of the L-shaped plate, and the two stabilizing rods are fixedly connected to the mounting frame and slidably connected to the two stabilizing frames respectively.

[0010] The reinforcement assembly includes multiple stabilizing plates and two reinforcing plates. The multiple stabilizing plates are fixedly connected between the L-shaped plate and the base, and the two reinforcing plates are fixedly connected to the side of the L-shaped plate.

[0011] This utility model discloses a bending die for processing automotive parts. When using the die, the corresponding stamping die and bending die are selected according to the parts to be processed. The stamping die is installed on the bending assembly, and the bending die and the fixing plate are inserted into the replacement slot on the base, aligning multiple replacement holes with multiple fixing holes. Multiple fixing bolts are screwed into the multiple fixing holes and multiple replacement holes respectively, thus fixing the bending die. At this point, the parts can be placed on the bending die, and the bending assembly is activated, causing the stamping die to press down. In conjunction with the bending die, the parts are stamped and bent. This avoids the problem that existing automotive part bending dies cannot be replaced and can only be bent at one angle. For bending at other angles, a different die is required, making it difficult to meet the bending requirements of different parts. This invention improves the applicability of the die.

[0020] This utility model provides a bending die for processing automotive parts: it includes a base 1, an L-shaped plate 2, and a die replacement mechanism. The die replacement mechanism includes a bending assembly 3, a stamping die 4, a bending die 5, a fixing plate 6, multiple fixing bolts 7, and a reinforcing assembly 8. The bending assembly 3 includes a cylinder 12, a stamping shaft 13, a connecting piece 14, and a stabilizing piece 15. The connecting piece 14 includes a mounting frame 16, a connecting block 17, and multiple mounting bolts 18. The stabilizing piece 15 also includes two stabilizing frames 19 and two stabilizing rods 20. The reinforcing assembly 8 includes multiple stabilizing plates 21 and two reinforcing plates 22. The aforementioned solution solves the problem that existing automotive part bending dies cannot be replaced and can only be bent at one angle. When bending at other angles, a different die is required, making it difficult to meet the bending requirements of different parts.

[0021] In this specific embodiment, the L-shaped plate 2 is fixedly connected to the top of the base 1. The base 1 is provided with a replacement groove 9 and multiple fixing holes 10. The bending assembly 3 is disposed on the L-shaped plate 2. The stamping die 4 is disposed below the bending assembly 3. The bending die 5 is slidably connected to the base 1 and located within the replacement groove 9. The fixing plate 6 is fixedly connected to the bottom of the bending die 5 and is provided with multiple replacement holes 11 that respectively mate with the multiple fixing holes 10. Multiple fixing bolts 7 are threadedly connected to the base 1 and pass through the multiple replacement holes 11, and are respectively located within the multiple fixing holes 10. The reinforcing assembly 8 is disposed on the base 1. When using a mold on the L-shaped plate 2, select the corresponding stamping mold 4 and bending mold 5 according to the parts to be processed. Install the stamping mold 4 on the bending assembly 3. Insert the bending mold 5 and the fixing plate 6 into the replacement groove 9 on the base 1, align the multiple replacement holes 11 with the multiple fixing holes 10, and screw the multiple fixing bolts 7 into the multiple fixing holes 10 and the multiple replacement holes 11 respectively. The bending mold 5 is then fixed. At this time, the parts can be placed on the bending mold 5. Start the bending assembly 3 to press down the stamping mold 4, and cooperate with the bending mold 5 to perform stamping and bending processing on the parts.

[0022] The cylinder 12 is fixedly connected above the L-shaped plate 2, the stamping shaft 13 is fixedly connected to the output end of the cylinder 12 and passes through the L-shaped plate 2, the connecting member 14 is disposed between the stamping shaft 13 and the stamping die 4, and the stabilizing member 15 is disposed on the L-shaped plate 2. When installing the stamping die 4, the stamping die 4 is installed below the stamping shaft 13 through the connecting member 14. When performing stamping and bending processing, the cylinder 12 is activated, the stamping shaft 13 moves downward, and the stamping die 4 is driven to press down through the connecting member 14, cooperating with the bending die 5 to stamp and bend the parts. Under the action of the stabilizing member 15, the downward pressing of the connecting member 14 and the stamping die 4 is more stable, increasing the accuracy of the die.

[0023] Secondly, the mounting frame 16 is fixedly connected to the lower part of the stamping shaft 13, the connecting block 17 is fixedly connected to the stamping die 4 and slidably connected to the mounting frame 16, and a plurality of mounting bolts 18 are threadedly connected to the mounting frame 16 and pass through the connecting block 17. When installing the stamping die 4, the connecting block 17 is inserted into the mounting frame 16, and the plurality of mounting bolts 18 are screwed into the mounting frame 16 and pass through the connecting block 17.

[0024] Meanwhile, the two stabilizing frames 19 are fixedly connected to the top of the L-shaped plate 2, and the two stabilizing rods 20 are fixedly connected to the mounting frame 16 and slidably connected within the two stabilizing frames 19 respectively. When the stamping shaft 13 is raised and lowered, it drives the mounting frame 16, the connecting block 17, and the stamping die 4 to be raised and lowered. When the mounting frame 16 is raised and lowered, it drives the two stabilizing rods 20 to be raised and lowered along the two stabilizing frames 19 respectively, thereby restricting the mounting frame 16 so that it cannot rotate horizontally, making the raising and lowering of the stamping die 4 more stable, thereby reducing the vibration frequency of the stamping die 4 and improving the accuracy of the die.

[0025] Finally, multiple stabilizing plates 21 are fixedly connected between the L-shaped plate 2 and the base 1, and two reinforcing plates 22 are fixedly connected to the side of the L-shaped plate 2. The multiple stabilizing plates 21 can increase the firmness of the connection between the L-shaped plate 2 and the base 1, and the two reinforcing plates 22 can enhance the firmness of the L-shaped plate 2, making it difficult to deform. The multiple stabilizing plates 21 and the two reinforcing plates 22 cooperate with each other to extend the service life of the mold and reduce the vibration amplitude of the L-shaped plate 2 when using the mold, making the bending assembly 3 more stable during operation and improving the accuracy of the mold.

[0026] When using the mold, select the corresponding stamping mold 4 and bending mold 5 according to the parts to be processed. Insert the connecting block 17 into the mounting frame 16, and screw the multiple mounting bolts 18 into the mounting frame 16, passing through the connecting block 17, thereby installing the stamping mold 4 on the bending assembly 3. Insert the bending mold 5 and the fixing plate 6 into the replacement slot 9 on the base 1, aligning the multiple replacement holes 11 with the multiple fixing holes 10. Screw the multiple fixing bolts 7 into the multiple fixing holes 10 and the multiple replacement holes 11 respectively, thus completing the fixing of the bending mold 5. At this time, the parts can be placed on the bending mold 5. Start the cylinder 12, and the stamping shaft 13 moves downward. Through the mounting frame 16, the connecting block 17, and the multiple mounting bolts 18, the stamping mold 4 is driven to press down, cooperating with the bending mold 5 to stamp and bend the parts, performing stamping and bending processing on the parts; when the stamping shaft 13 moves up and down, it drives the parts to press down. The mounting frame 16, the connecting block 17, and the stamping die 4 are raised and lowered. When the mounting frame 16 is raised and lowered, it drives the two stabilizing rods 20 to rise and fall along the two stabilizing frames 19 respectively, thereby restricting the mounting frame 16 and preventing it from rotating horizontally. This makes the raising and lowering of the stamping die 4 more stable, thereby reducing the vibration frequency of the stamping die 4 and improving the accuracy of the die. The two reinforcing plates 22 can enhance the firmness of the L-shaped plate 2, making it less prone to deformation. The multiple stabilizing plates 21 and the two reinforcing plates 22 cooperate with each other to extend the service life of the die and reduce the vibration amplitude of the L-shaped plate 2 when using the die. This makes the bending assembly 3 more stable during operation, improves the accuracy of the die, and avoids the problem that existing automotive part bending dies cannot be replaced and can only be bent at one angle. When bending at other angles, a different die is required, which makes it difficult to meet the bending requirements of different parts. This achieves the effect of improving the applicability of the die.
