Description

Technical Field

[0001] This utility model belongs to the field of mechanical processing technology, and specifically relates to a flat steel shearing machine. Background Technology

[0002] Flat steel is a type of steel with a rectangular cross-section and slightly blunt edges. Flat steel can be a finished product, or it can be used as raw material for welded pipes and as slab blanks for rolled thin plates. As a finished product, flat steel can be used to manufacture square tubes and is applied in various industrial applications.

[0003] In the use of flat steel, it is usually necessary to cut it according to a certain specification and length for subsequent use. Flat steel is generally cut using strip steel as raw material. The strip steel is longitudinally sheared to form a steel sheet, which is then transversely cut to form flat steel of a certain length. However, in existing shearing mechanisms, the steel sheet is mainly transported by rollers, which may cause the steel sheet under the cutter to tilt. This results in a tilted cut on the flat steel, affecting its quality and consequently the quality of the square tubes made from it. Publication number CN 208051013U discloses a CNC flat steel shearing machine that uses a pressing mechanism and a correction mechanism to position the flat steel, making the cutting position more accurate. However, it only performs the cutting function and cannot control the dimensional specifications of the flat steel, thus failing to meet current shearing requirements.

[0004] Therefore, the above-mentioned problems should be considered and solved during the shearing process of flat steel. Utility Model Content

[0005] To address the above problems and solve the aforementioned technical issues, this utility model discloses a flat steel shearing machine, the specific technical solution of which is as follows:

[0006] This utility model provides a flat steel shearing machine, including a frame and a shearing mechanism, a material dragging mechanism, and a mold mechanism for adjusting the size of the flat steel, all mounted on the frame. The shearing mechanism includes a fixed base and a driving device mounted on the fixed base. The driving device is equipped with a shearing tool and includes a driving cylinder and a driving oil cylinder, which control the forward and backward and left and right movements of the shearing tool, respectively. The material dragging mechanism has a moving mechanism at its bottom and includes a support, a pull rod at one end of the support, and a clamping part at the other end of the support. A rolling chain is provided in the middle of the frame, and the outer end of the pull rod is fixed to the rolling chain.

[0008] A further improvement of this utility model is that the moving mechanism includes a moving plate and moving wheels disposed on both sides of the moving plate, the moving wheels being disposed on both sides of the limiting track.

[0009] A further improvement of this utility model is that: the end of the pull rod is provided with a hook, and the hook is attached to the rolling chain.

[0010] A further improvement of this utility model is that: a support frame is provided on one side of the frame, and two parallel sliding rods are provided inside the support frame. The fixed seat is slidably disposed on the sliding rods. The drive cylinder is fixed on the support frame, and its output end is connected to the fixed seat. The drive oil cylinder is fixed on the fixed seat, and its output end is connected to the shear.

[0011] A further improvement of this utility model is that: the clamping part includes four fixed posts arranged in a rhombus shape, a sliding groove is provided on the center line of the moving plate, one of the fixed posts is disposed in the sliding groove, a connecting rod is hinged between two adjacent fixed posts, and a clamp is provided at the end of the connecting rod.

The driving cylinder 6 is fixed to the support frame 2, and its output end is connected to the fixed base 3. The driving cylinder 7 is fixed to the fixed base 3, and its output end is connected to the shearing tool 4.

[0024] The frame 1 includes support legs 8 and limiting rails 9 parallel to the support legs 8. The two ends of the limiting rails 9 are connected by rotating rods 10. A rolling chain 11 is provided in the middle of the frame and is wound around the rotating rods 10. One of the rotating rods 10 is connected to a drive motor 12. The bottom of the material dragging mechanism is provided with a moving mechanism, which includes a moving plate 13 and moving wheels 14 disposed on both sides of the moving plate 13. The moving wheels 14 are respectively disposed on both sides of the limiting rails 9. The material handling mechanism includes a support 15, a pull rod 16 disposed at one end of the support 15, and a clamping part disposed at the other end of the support 15. The clamping part includes four fixed posts 17 arranged in a rhomboid shape, with a connecting rod 18 hinged between adjacent fixed posts. A clamp 19 is provided at the end of the connecting rod 18. A groove 25 is provided on the center line of the moving plate 13, with the fixed posts 17 near the clamp disposed within the groove 25. A hook 20 is provided at the end of the pull rod 16, and the hook 20 is hooked onto the rolling chain 11.

[0026] The flat steel shearing machine provided in this embodiment works as follows: When shearing the flat steel, the flat steel passes through the die hole, the limiting hole, and the clamping part in sequence. First, the clamp 19 is manually clamped to hold the flat steel. Then, the drive motor 12 is started, which drives the rolling chain 11 to rotate. While the rolling chain rotates, the hook 20 moves the clamping part to a suitable position, pulling the flat steel backward. As the flat steel is pulled backward, the pulling force compresses the flat steel to a suitable specification and size when it passes through the extrusion die 22. Then, the drive cylinder 6 is started, which drives the support frame 2 to move forward, that is, it drives the shear 4 to move forward. Then, the drive cylinder 7 is started, which pushes the shear 4 toward the flat steel to perform shearing. After shearing is completed, the drive cylinder 7 and the drive cylinder 6 drive the shear 4 to reset. Then, the drive motor 12 is started again to reset the clamping part, and the next round of operation can begin.
