Description

Technical Field

[0001] This utility model relates to the field of punch press technology, and in particular to a die cavity guiding device for punch presses. Background Technology

[0002] Punch presses, as a common metal processing equipment, occupy a crucial position in the manufacturing industry. They utilize dies to punch, bend, and stretch metal sheets, making them essential equipment for producing various metal parts and components. In the operation of a punch press, the material guiding device is a critical component, and its performance has a decisive impact on processing efficiency and product quality. Especially in the core step of guiding long strips of sheet metal into the die cavity of the punch press, the accuracy and stability of the material guiding device are paramount.

[0003] However, existing die cavity guiding devices for punch presses have gradually revealed significant limitations when processing long strips of sheet metal. Specifically, existing guiding devices lack effective guidance functions to correct for drooping, warping, or skewed sections of the sheet metal during the process of guiding it into the die cavity. This often results in the sheet metal not accurately entering the die cavity during processing, causing problems such as inaccurate positioning and punching deviations.

[0004] These problems directly lead to reduced punching efficiency and increased operational complexity. Inaccurate sheet metal feeding requires operators to spend more time and effort on adjustments and corrections, severely impacting production efficiency. Furthermore, inaccurate positioning and punching deviations can also lead to decreased product quality, making it difficult to meet the demands of high-precision, high-volume production. More seriously, these problems may also increase the risks during processing, posing potential threats to operator safety and the stable operation of equipment.

[0005] Therefore, given the numerous shortcomings of existing technologies, we urgently need a die cavity guiding device for punch presses to solve this problem. This guiding device should be able to effectively guide the sheet metal to correct drooping, warping, and skewing, significantly improving the accuracy and stability of sheet metal feeding, thereby increasing the processing efficiency and product quality of the punch press.

The top of the mounting base is provided with a bidirectional drive structure for cooperating with the two mounting plates.

[0013] Preferably, a movable plate is provided on one side of the mounting plate, and two guide rods are provided at the top between the mounting plate and the movable plate.

[0032] Mounting base 2: Mounting base 2 is the basic support structure of the material guide assembly, used to fix and support the two material guide structures.

[0033] Mounting plate 7: Mounting plate 7 is a supporting and connecting component of the material guiding structure, used to fix and support the guide block 6, the material guiding side plate 3, and other structures. Its top side is connected to the guide block 6, and its bottom side engages with the sliding groove 15 of the mounting base 2 via a slider 9, enabling lateral movement. Simultaneously, mounting plate 7 also engages with the bidirectional drive structure, connecting to the bidirectional lead screw 14 via a flange nut, allowing for rapid adjustment of the material guiding structure.

[0034] Guide plate 5: Guide plate 5 forms the initial guiding channel for the board material, ensuring that the board material can maintain a straight movement during the introduction process and avoid deviation. The horizontal groove 11 opened at its top cooperates with the adjusting bolt to adjust the position of the guide block 6, thereby changing the height and direction of the guiding channel.

[0035] Guide block 6: Guide block 6 is the connecting bridge between guide plate 5 and material guide side plate 3. By adjusting its position, the shape and size of the guide channel and the material guide channel can be changed.

[0036] Guide side plate 3: The guide side plate 3 cooperates with the guide plate 4 to form a funnel-shaped guide channel, which can effectively receive and guide the material into the channel. The adjustment grooves 8 on the top and bottom of one side cooperate with the adjustment bolts to adjust the angle and position of the guide plate 4.

[0037] Guide plate 4: Guide plate 4 is an important part of the material guiding channel. Its inclined and flared design can adapt well to the initial position of the material. No matter if the material is slightly drooping, tilted or deviated, it can be gradually guided by guide plate 4 to ensure that the material can enter the mold cavity accurately and stably.

[0038] The material guiding assembly includes a mounting base 2 and two symmetrically arranged material guiding structures;

[0039] The material guiding structure includes a mounting plate 7, two guide plates 5, a guide block 6, a material guiding side plate 3, and two guide plates 4;

[0040] Two guide plates 5 are respectively connected to the top and bottom of the guide block 6. Two guide plates 4 are symmetrically and obliquely connected to one side of the guide side plate 3. The guide side plate 3 is obliquely connected to one side of the guide block 6. The guide block 6 is connected to the top of one side of the mounting plate 7.

[0041] The openings on the sides of the two guide plates 4 that are close to each other are connected to the two guide plates 5. Both mounting plates 7 are slidably connected to the top of the mounting base 2. The top of the mounting base 2 is provided with a bidirectional drive structure for cooperating with the two mounting plates 7.

[0042] Example 2

[0043] Please see Figure 1-5 As shown in this embodiment, a die cavity guiding device for a punch press has a movable plate 13 on one side of a mounting plate 7. Two guide rods 10 are positioned at the top between the mounting plate 7 and the movable plate 13. One end of each guide rod 10 is connected to the mounting plate 7, and the other end slides through the movable plate 13 and is connected to a limiting screw sleeve. An elastic element is provided around the outer ring of each guide rod 10. One end of the elastic element is connected to the mounting plate 7, and the other end is connected to the movable plate 13. Specifically, during operation, when the thickness or position of the sheet metal changes, the movable plate 13 can slide on the guide rods 10. A compression spring 12 provides a buffering force, allowing the guiding structure to adapt to changes in the sheet metal and maintain a stable guiding effect. This enhances the adaptability of the guiding device, enabling it to handle sheets of different thicknesses and positions, thus improving processing flexibility and stability.

[0044] The top of the mounting base 2 has a sliding groove 15. The bottoms of both the mounting plate 7 and the movable plate 13 are connected to sliders 9 that fit the sliding groove 15. The elastic element is a compression spring 12, with one end connected to the side wall of the mounting plate 7 and the other end connected to the side wall of the movable plate 13. Specifically, the top of the mounting base 2 has a sliding groove 15, and the bottoms of both the mounting plate 7 and the movable plate 13 are connected to sliders 9 that fit the sliding groove 15. In this way, the mounting plate 7 and the movable plate 13 can slide along the sliding groove 15, realizing the lateral movement of the material guiding structure. This achieves the effect of conveniently adjusting the position of the material guiding structure, allowing the device to quickly adjust the material guiding position according to processing requirements, improving processing efficiency and convenience.

[0045] The bidirectional drive structure includes a bidirectional lead screw 14 that is threadedly engaged with the mounting plate 7 and the movable plate 13 via flange nuts. Both ends of the bidirectional lead screw 14 are connected to the top of the mounting base 2 via rotating seats, and one end of the bidirectional lead screw 14 is connected to a handwheel 16. A through hole with a diameter larger than the diameter of the bidirectional lead screw 14 is provided on the bottom side of the mounting plate 7 near the movable plate 13. Specifically, the bidirectional lead screw 14 is threadedly engaged with the mounting plate 7 and the movable plate 13 via flange nuts, and both ends of the bidirectional lead screw 14 are connected to the top of the mounting base 2 via rotating seats, with one end connected to a handwheel 16. By rotating the handwheel 16, the bidirectional lead screw 14 can be driven to rotate, thereby causing the mounting plate 7 and the movable plate 13 to move simultaneously in opposite directions, achieving rapid adjustment of the material guiding structure. This achieves the effect of convenient and rapid adjustment of the spacing of the material guiding structure, allowing the device to quickly adjust the width of the material guiding channel according to the width of the sheet material, improving processing efficiency and convenience.

[0046] Example 3

[0047] Please see Figure 1-5 As shown in this embodiment, a die cavity guiding device for a punch press has several adjusting grooves 8 on both the top and bottom of one side of the guiding side plate 3. An adjusting bolt, connected at one end to a guide plate 4, is threaded into the internal part of each adjusting groove 8. Specifically, by rotating the adjusting bolt, the angle and position of the guide plate 4 can be adjusted, thereby changing the width and shape of the guiding channel. This achieves the effect of conveniently adjusting the guiding channel, enabling the device to adapt to plates of different widths and shapes, and improving the accuracy and versatility of the guiding process.

[0048] A horizontal groove 11 is formed at the top of the guide plate 5. An adjusting bolt, one end of which is connected to the guide block 6, is threaded inside the groove 11. Specifically, by rotating the adjusting bolt, the position of the guide block 6 can be adjusted, thereby changing the height and direction of the guide channel. This achieves convenient adjustment of the guide channel, enabling the device to adapt to the feeding requirements of plates of different heights and directions, and improving the flexibility and accuracy of material feeding.

[0049] This solution includes the following workflow:

[0050] The material guiding device includes a punch press 1 and a material guiding assembly, which consists of a mounting base 2 and two symmetrically arranged material guiding structures. Each material guiding structure includes a mounting plate 7, two guide plates 5, a guide block 6, a material guiding side plate 3, and two guide plates 4. The two guide plates 5 are respectively connected to the top and bottom of the guide block 6, forming a preliminary guiding channel for the sheet metal to enter; the two guide plates 4 are symmetrically and obliquely connected to one side of the material guiding side plate 3, and the material guiding side plate 3 is in turn obliquely connected to one side of the guide block 6, forming a trumpet-shaped design to effectively receive and guide the sheet metal into the device.

[0051] During the operation of the punch press 1, the long strip of sheet metal is fed into the working area of ​​the punch press. First, the sheet metal comes into contact with two guide plates 4. Due to the inclined and flared design of the guide plates 4, they can adapt well to the initial position of the sheet metal. No matter if the sheet metal is slightly drooping, tilted, or deviated, it can be gradually guided into the correct position by the guide plates 4. Subsequently, the sheet metal enters the guide channel formed by two guide plates 5. This channel further ensures the linear movement of the sheet metal and avoids deviation during the feeding process.

[0052] To enhance the adaptability of the material guiding device, a movable plate 13 is provided on one side of the mounting plate 7, and the two are connected by a guide rod 10. One end of the guide rod 10 is fixed to the mounting plate 7, and the other end slides through the movable plate 13 and is connected to a limit screw sleeve. At the same time, a compression spring 12 is sleeved on the outer ring of the guide rod 10. When the thickness or position of the material changes, the movable plate 13 can slide on the guide rod 10, and the compression spring 12 provides a buffering force, so that the material guiding structure can adapt to the changes in the material and maintain a stable material guiding effect.

[0053] To facilitate adjustment of the material guide channel, several adjustment slots 8 are provided on the top and bottom of one side of the material guide side plate 3. Adjustment bolts are threaded into the adjustment slots 8, and one end of the adjustment bolts is connected to the guide plate 4. By rotating the adjustment bolts, the angle and position of the guide plate 4 can be adjusted, thereby changing the width and shape of the material guide channel. This allows the device to adapt to plates of different widths and shapes, improving the accuracy and versatility of material guiding.

[0054] In addition, the top of the mounting base 2 is provided with a sliding groove 15, and the bottom of both the mounting plate 7 and the movable plate 13 are connected to sliders 9 that are adapted to the sliding groove 15. In this way, the mounting plate 7 and the movable plate 13 can slide along the sliding groove 15, realizing the lateral movement of the material guiding structure, which facilitates the quick adjustment of the material guiding position according to processing requirements, thereby improving processing efficiency and convenience.

[0055] To further facilitate the adjustment of the guide channel, a horizontal groove 11 is provided on the top of the guide plate 5. An adjusting bolt is threaded into the horizontal groove 11, and one end of the adjusting bolt is connected to the guide block 6. By rotating the adjusting bolt, the position of the guide block 6 can be adjusted, thereby changing the height and direction of the guide channel. This allows the device to adapt to the feeding requirements of plates of different heights and directions, improving the flexibility and accuracy of material feeding.

[0056] Finally, the top of the mounting base 2 is equipped with a bidirectional drive structure for cooperating with the two mounting plates 7. This structure includes a bidirectional lead screw 14 that is threadedly engaged with the mounting plates 7 and the movable plate 13 via flange nuts. Both ends of the bidirectional lead screw 14 are connected to the top of the mounting base 2 via rotating seats, and one end is connected to a handwheel 16. By rotating the handwheel 16, the bidirectional lead screw 14 can be driven to rotate, thereby causing the mounting plates 7 and the movable plate 13 to move simultaneously in opposite directions. This enables rapid adjustment of the material guiding structure, allowing the device to quickly adjust the width of the material guiding channel according to the width of the material, further improving processing efficiency and convenience.
