Description

A rapid positioning and shearing device for mold steel plates

Technical Field

The invention relates to the technical field of steel plate shearing devices, in particular to a rapid positioning shearing device for a mould steel plate.

Background Art

Steel plate refers to a flat steel plate that is cast with molten steel and pressed after cooling. In order to meet the fixed length requirements of the finished product during the production process, a shearing device is often used to cut the steel plate into fixed lengths.

When installing the mold, traditional shearing devices often use bolts to fix the four corners of the mold on the operating table. Therefore, when changing molds of different sizes, it is necessary to repeatedly disassemble and install the bolts, resulting in cumbersome operation and poor flexibility.

When cutting steel plates, it is necessary to manually align the steel plates one by one and insert them into the mold, and to manually push them slowly to complete the shearing of the steel plates. As a result, it is difficult to accurately align the mold when inserting, and the shearing efficiency of the steel plates is low;

In order to meet the requirements of cutting steel plates to a fixed length, the cut length is usually measured manually by visual measurement. However, due to errors in human visual observation, it is difficult to ensure that the lengths of the cut steel plates are the same, and the cutting accuracy is low.

At this time, the first slide plate 501 drives the second slide plate 502 and the other second connecting plate 508 to move in opposite directions, so that the two second connecting plates 508 can be pulled apart to both sides, so that the other hand can place the mold 7 between the two second connecting plates 508, and then slowly release the two second connecting plates 508, the first spring 507 resets and drives the two second slide plates 502 and the second connecting plates 508 to move toward the middle, so that the two second connecting plates 508 clamp The mold 7 is convenient to replace molds 7 of different sizes, and because the sliding distances of the first rack 503 and the second rack 504 are the same, the two second connecting plates 508 are guaranteed to move the same distance per unit time, which can play a positioning role for the mold 7 and ensure that the center position of the mold 7 is always placed directly below the hydraulic cylinder 10. The operation is simple and the flexibility is strong. When the two second connecting plates 508 clamp the mold 7, the second connecting plates 508 are released, and the first connecting plate 401 moves along the guide under the tension of the tension spring 403. The rod 402 slides downward, and the first connecting plate 401 drives the two second connecting plates 508 and the pressing block 604 to move downward until the pressing block 604 contacts the four corners of the bottom edge of the mold 7. At this time, the mold 7 can be initially fixed, and then the knob 407 is turned, and then the knob 407 drives the third screw rod 405 to rotate inside the mounting shell 404, and the third screw rod 405 drives the pressing plate 406 to press the upper surface of the first connecting plate 401 downward, so as to further press and fix the mold 7, and the stability is strong;

When it is necessary to fix molds 7 of different lengths, the positions of the four pressing blocks 604 can be adjusted by sliding the slider 602 left and right in the second slide groove 601.

After the installation of the mold 7 is completed, two support plates 201 are installed on the shearing machine body 1, and the pile of steel plates are transported to the conveyor belt 206. Then, the first screw rod 303 is rotated in the support plate 201 by twisting the grip rod 307, and then the first screw rod 303 drives the baffle plate 302 to slide up and down in the first slide groove 301 until the distance between the bottom end of the baffle plate 302 and the conveyor belt 206 is the thickness of a steel plate, ensuring that the conveyor belt 206 only drives one steel plate to move at a time, and then the second screw rod 304 is driven by the second motor 306 to rotate, and the second screw rod 304 drives the two push plates 305 to move toward the middle direction until the two push plates 305 push the steel plate pile on the conveyor belt 206 to the middle of the conveyor belt 206, and at the same time, the two push plates 305 are respectively fitted with the two sides of the steel plate, so as to align the steel plate with the mold 7, which is beneficial to the subsequent shearing of the steel plate and improves the shearing efficiency.

When the steel plate on the conveyor belt 206 is aligned with the mold 7, the first rotating shaft 202 is driven by the first motor 207 to rotate, and since the first rotating shaft 202 and the second rotating shaft 203 are respectively fixed with the first pulley 204 and the second pulley 205, and the first pulley 204 and the second pulley 205 are transmitted through the conveyor belt 206, the steel plate on the conveyor belt 206 is transported toward the mold 7, and the baffle 302 will contact the upper steel plate, ensuring that only one steel plate is sheared at a time, and the flexibility is strong;

In order to realize the cutting of the steel plate to a fixed length, firstly, the bolt 809 on the side of the mold 7 is twisted so that the bolt 809 no longer conflicts with the scale plate 801, and the distance that the scale plate 801 is pulled outward is adjusted by observing the scale bar 808 on the scale plate 801, and then the bolt 809 is tightened in the reverse direction to fix the scale plate 801. Then, in the process of conveying the steel plate, the front end of the steel plate conflicts with the measuring plate 805. At this time, the first motor 207 is turned off, and at the same time, the hydraulic cylinder 10 on the gantry 9 drives the shear blade on the mold 7 to cut the steel plate, thereby completing the cutting of the steel plate to a fixed length. The operation is simple. When there is no need to control the cutting length, just move the hydraulic cylinder 10 upward. Pull the pull bar 803, and then the pull bar 803 drives the block 804 to slide out of the limit groove 802. At this time, the pull bar 803 drives the connecting ring 806 to contact the inside of the scale plate 801. At the same time, the measuring plate 805 compresses the second spring 807, and then the measuring plate 805 is rotated. At this time, the upper surface of the connecting ring 806 and the inside of the scale plate 801 rotate, which can effectively prevent the second spring 807 from being deformed. At this time, the measuring plate 805 no longer blocks the steel plate, and then the pull bar 803 is released. The block 804 moves downward under the resetting action of the second spring 807 and engages with the limit groove 802, thereby effectively preventing the measuring plate 805 from rotating, and having strong stability.
