Description

Technical Field

[0001] The invention relates to the technical field of die steel cutting, in particular to a die steel rapid positioning cutting machine. Background Art

[0002] Mold steel is a special steel material specially used for manufacturing various molds. It has the advantages of high hardness, high strength, good wear resistance, good corrosion resistance, easy cutting and good thermal stability. Mold steel rod is a common mold steel, which is suitable for manufacturing the main parts of molds, such as mold cores, mold columns, etc. It usually has good strength, toughness and processing performance. In mold manufacturing or other industrial applications, in order to meet specific manufacturing or processing requirements, it is necessary to cut the mold steel rod at a fixed distance to ensure that the cut mold steel rod can accurately meet the size requirements of mold manufacturing or other industrial applications.

[0003] At present, there are the following disadvantages in cutting steel bars: 1. Before cutting the mold steel bar, it is usually necessary to limit and fix the required cutting part by pressing the side and the top, but the front end of the mold steel bar is not adaptively pressed, so that the waste material breaks without being completely cut off during the cutting process, resulting in an irregular cutting surface of the mold steel bar, affecting the quality and accuracy of the cutting surface, and the waste material will be offset due to cutting force or vibration, resulting in accidental contact between the cutting tool and the waste material, increasing the risk of tool damage; 2. In the process of cutting the mold steel bar, smoke and debris will be generated, and the smoke and debris will adhere to the cutting tool or material surface, thereby affecting the accuracy and quality of the cutting, resulting in an uneven cutting surface or dimensional deviation; 3. In the process of cutting the mold steel bar, the pressing ends of the top and the side will have a time difference in the pressing of the top and the side due to different drives, resulting in displacement of the steel bar during the cutting process, thereby affecting the straightness and dimensional accuracy of the cutting, and resulting in uneven distribution of cutting force, resulting in burrs, cracks or other defects on the cutting surface.

[0049] At this time, the third electric push rod 615 can be started to push the second spring rod 613 upward in the limiting slide cylinder 612 through the slide rail 614, and the second spring rod 613 will bring the platform block 623 to push the third spring rod 622 out of the lock hole 621 and insert it into the socket, and the side pressure block 515 and the limiting slide cylinder 612 are locked by the third spring rod 622, so that the side pressure block 515 is fixed on the operating table 2 in a fixed state.

[0050] When the second spring rod 613 moves upward, the first piston rod 632 will move upward, thereby pushing the second piston rod 633 downward through the U-shaped hydraulic pipe 631, so that the lower end of the second piston rod 633 contacts the circular pressure plate 634 and presses it into the matching hole. Under the top pressure of the matching hole, the L-shaped clamping plate 635 will approach the buckle plate, and when the circular pressure plate 634 is completely immersed in the matching hole, the surrounding L-shaped clamping plate 635 will clamp the buckle plate, locking the side pressure block 515 and the upper pressure block 525, and the side pressure block 515 and the operating table 2 are in a relatively locked state, thereby completing the locking of the upper pressure block 525, thereby connecting and locking the upper and side pressure ends, so that the two are fixed on the operating table 2 in a fixed state, avoiding the synchronous vibration of the mold steel bar with the upper and side pressure ends during the cutting process, so as to ensure the stability of the material position during the cutting process.

[0051] See also Figure 1 , Figure 3 , Figure 4 and Figure 5 The chip suction part 43 includes a suction hole 431, a chip suction pipe 432 and an air pump 433. The cutting groove 411 has front-to-back symmetrical suction holes 431 in a linear array. The lower end surface of the operating table 2 is fixedly equipped with a chip suction pipe 432 connected to the suction hole 431 on the same side. The operating table 2 is fixedly equipped with an air pump 433 whose extraction end is simultaneously connected to the front-to-back symmetrical chip suction pipe 432.

[0052] During specific operation, when the fixing mechanism 5 completes the limiting of the mold steel rod, the cutting knife 412 and the first electric push rod 413 are started, so that the first electric push rod 413 moves with the cutting knife 412 to the cutting groove 411, thereby cutting the mold steel rod, and at the same time, the vacuum pump 433 is started to extract the debris and smoke generated by the cutting through the suction hole 431 and the chip suction pipe 432, so as to prevent the smoke and debris from adhering to the cutting tool or material surface.

[0053] Working principle: When the mold steel bar needs to be cut, the mold steel bar is placed on the operating table 2 and placed between the positioning roller 422 and the transport roller 423. Then the second electric push rod 424 is started to push the mold steel bar against the positioning roller 422 through the transport part 42, thereby completing the pre-positioning of the mold steel bar and transporting its cutting part to the cutting groove 411.

[0054] When the mold steel bar is transported to the cutting groove 411, the first motor 425 is stopped and the second motor 512 is started to press the mold steel bar against the side support plate 517 through the side fixing part 51. At the same time, the first transmission shaft 521 presses the upper end of the mold steel bar through the side fixing part 51 and the upper fixing part 52. During the rotation of the driving rod 513, the side fixing part 51 and the front sticking part 53 cooperate to bring the front pressure plate 535 to stick to the front end surface of the mold steel bar, so that the waste material will remain in the corresponding position when it is not completely cut off.

[0055] When the upper pressure block 525 descends, the positioning rod on the alignment plate 526 will be inserted into the slot on the side support plate 517, so that the upper pressure block 525 and the side support plate 517 are aligned and locked, and then the third electric push rod 615 is started to lock the side pressure block 515 and the limiting slide 612 through the driving part 61 and the inner locking part 62, so that the side pressure block 515 is fixed on the operating table 2.

[0056] At the same time, the first piston rod 632 moves upward, and the surrounding L-shaped clamping plate 635 clamps the buckle plate through the cooperation of the driving part 61 and the matching part 63, thereby locking the side pressure block 515 and the upper pressure block 525, and the side pressure block 515 and the operating table 2 are in a relatively locked state, thereby completing the locking of the upper pressure block 525.

[0057] When the fixing mechanism 5 completes the limiting of the mold steel rod, the cutting knife 412 and the first electric push rod 413 are started, so that the first electric push rod 413 moves with the cutting knife 412 toward the cutting groove 411, thereby cutting the mold steel rod, and at the same time, the vacuum pump 433 is started to extract the debris and smoke generated by the cutting through the suction hole 431 and the chip suction pipe 432.
