Description

Technical Field

[0001] This utility model relates to the field of metal processing technology, and in particular to a metal sheet cutting device. Background Technology

[0002] Metal sheet cutting equipment is widely used in industrial manufacturing, especially in the automotive, aerospace, and shipbuilding industries. With the continuous development of modern manufacturing, the requirements for the precision and efficiency of metal sheet processing are becoming increasingly stringent. Existing metal sheet cutting equipment, through automation and precision control technology, has significantly reduced manual labor intensity while improving production efficiency. However, traditional metal sheet cutting equipment still has some shortcomings in practical applications and urgently needs improvement.

[0003] To achieve precise positioning and stable fixation of metal sheets, common methods in existing technologies include the use of fixing clamps. Fixing clamps typically employ a rigid structure design, providing strong clamping force and are suitable for mass production applications.

[0004] However, when cutting metal sheets, many fixed furniture pieces clamp a portion of the metal sheet while placing the other portion to be cut on the outside of the sheet before cutting. But some metal sheets are cut closer to the center, which means that most of the metal sheet needs to be placed on the outside of the fixed furniture, resulting in poor clamping effect. Utility Model Content

[0019] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0020] according to Figure 1-3This utility model provides a metal sheet cutting device, including: a base 1, a sliding block 2, a motor 3, a drive rod 4, a pushing structure 5, a telescopic structure 6, a belt 7, and a cutting structure 8.

[0021] Two sliding blocks 2 are slidably disposed opposite each other on both sides of the base 1. Each sliding block 2 includes a sliding groove 21, a clamping plate 22, and a limiting groove 23. The two clamping plates 22 are slidably disposed within the sliding groove 21. The two limiting grooves 23 are formed on both sides of the sliding groove 21. A limiting plate 221 is provided on the side of the clamping plate 22 closest to the sliding groove 21. The limiting plate 221 is slidably disposed within the limiting groove 23.

[0022] When cutting a metal sheet, the two sliding blocks 2 are brought close together to a certain position, and then the metal sheet is placed on the sliding blocks 2. Since there are two clamping plates 22 in one sliding groove 21, and they can slide within the sliding groove 21, the position of the movable clamping plates 22 is adjusted. Then, the sliding blocks 2 are brought close together again, so that the clamping plates 22 fix the metal sheet. By changing the position of the clamping plates 22, the two clamping plates 22 can be fixed at both ends of one side of the metal sheet. That is, with the two clamping plates 22 at both ends of one side of the metal sheet, the middle position of the metal sheet is not in direct contact with the clamping plates 22, allowing for direct cutting at the center while maintaining good fixation of the metal sheet. Furthermore, because the clamping plates 22 and the metal sheet are pressed together, the sliding clamping plates 22 cannot move, thus maintaining fixation while clamping the metal sheet. A limiting plate 221 matching the limiting groove 23 is provided on the clamping plate 22, so that the limiting plate 221 limits the clamping plate 22 in the connecting groove 222, preventing the clamping plate 22 from tipping over or falling off.

[0023] One of the clamping plates 22 has a connecting groove 222 on the side near the sliding groove 21, and the other clamping plate 22 has a connecting block 223 on the side near the sliding groove 21. The connecting block 223 is disposed within the connecting groove 222. The connecting block 223 can slide within the connecting groove 222.

[0024] When the clamping plate 22 moves with the sliding block 2, although there is a certain friction between the clamping plate 22 and the limiting groove 23, it is not easy to move. However, the movement may cause shaking and position shift. This utility model enhances the connection between the two clamping plates 22 by allowing the connecting block 223 of one clamping plate 22 to slide into the connecting groove 222 of the other clamping plate 22. This makes it more difficult for the clamping plate 22 to shift, making the clamping position more accurate. Moreover, it has little impact on the manual control of the position of the two plates in the sliding groove 21.

[0025] An electric wheel 31 is provided on one side of the motor 3. The drive rod 4 includes a connecting wheel 41 and a drive wheel 42. Two drive wheels 42 are located on both sides of the drive rod 4. The connecting wheel 41 is located between the two drive wheels 42. The connecting wheel 41 meshes with the electric wheel 31. The push structure 5 includes a push rod 51 and a rotating wheel 52. The rotating wheel 52 meshes with the drive wheel 42. The push rod 51 is located on the side of the rotating wheel 52 near the sliding block 2. The push rod 51 has a thread on the side near the sliding block 2. The two ends of the belt 7 are respectively fitted onto the push rods 51 of the two push structures 5. The telescopic structure 6 includes a telescopic cylinder 61 and a telescopic rod 62. The telescopic rod 62 is slidably located inside the telescopic cylinder 61. The telescopic cylinder 61 is located on the side of the telescopic rod 62 near the push rod 51. The telescopic cylinder 61 has a threaded groove on the side near the push rod 51. The telescopic structure 6 also includes a push plate 63. The push plate 63 is located on the side of the telescopic rod 62 near the sliding block 2.

[0026] When motor 3 is started, the electric wheel 31 rotates, which in turn drives the connecting wheel 41 to rotate, causing the drive rod 4 to rotate as a whole, i.e., the drive wheel 42 to rotate. The rotation of the drive wheel 42 causes the rotating wheel 52 to rotate, which in turn causes the push rod 51 to rotate. Since the push rod 51 has a thread on one side and the telescopic cylinder 61 has a threaded groove on the side near the push rod 51, the push rod 51 moves towards the telescopic cylinder 61 as it rotates, pushing the telescopic rod 62 towards the sliding block 2. This causes the sliding blocks 2 to move closer together, clamping the metal sheet. As shown in the figure, when the drive motor 3 causes the drive rod 4 to rotate as a whole, the sliding blocks 2 on both sides of the base 1 move closer together simultaneously. When clamping the metal sheet, it can automatically clamp it to the center position of the base 1 without any further adjustments, making it convenient to use. It also ensures that the force on both sides of the metal sheet is consistent, maintaining a relatively uniform force distribution. When the push rod 51 moves, it drives the rotating wheel 52 to move as well. The drive wheel 42 of this invention has a relatively large thickness so that the rotating wheel 52 can match the drive wheel 42 when it moves, preventing the push structure 5 from disengaging from the drive wheel 42. A push plate 63 is also provided on the side of the telescopic rod 62 near the sliding block 2 to increase the base area when in contact with the sliding block 2, preventing the sliding block 2 from being damaged due to excessive local force. This invention has two push structures 5 and a telescopic structure 6 on the same side of the sliding block 2. The two push structures 5 can rotate and move together through the belt 7, making it easy to use.

[0027] Working principle and usage process of this utility model:

[0028] When cutting a metal sheet, first place the metal sheet between two sliding blocks 2, then start the motor 3 to make the electric wheel 31 rotate. The electric wheel 31 drives the connecting wheel 41 to rotate, which in turn makes the drive rod 4 rotate as a whole, causing the drive wheel 42 to rotate. When the drive wheel 42 rotates, it drives the rotating wheel 52 to rotate, which in turn makes the push rod 51 rotate. At the same time, when the push rod 51 rotates, it also moves into the telescopic cylinder 61 and pushes the telescopic rod 62 to move towards the sliding block 2, so that the push plate 63 abuts against the sliding block 2, causing the sliding blocks 2 to move closer to each other. This makes the clamping plates 22 move closer to each other and contact the metal sheet, thereby clamping the metal sheet. Then, the cutting structure 8 can be used to cut the metal sheet.

[0029] In summary, this utility model, by setting two sliding clamping plates, allows the clamping plates to hold the metal sheet at both ends on one side, thereby exposing the middle of the metal sheet for easy processing, while also maintaining a good fixing effect on the metal sheet.

[0030] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
