[0002] Mold steel is a key basic material in fields such as automotive body panel molds, home appliance injection molds, and precision stamping molds, and its processing accuracy directly affects the quality of the final product. Sawing, as the first process in mold steel processing, has a decisive impact on the machining allowance and finished product qualification rate of subsequent milling, grinding, and other finishing processes. Currently, band saws or circular saws are commonly used for sawing mold steel.

[0015] The present invention has the following advantages over the prior art: 1. This invention provides a high-precision sawing device for mold steel. By setting two angled fixture base plates in conjunction with a rotating shaft and drive mechanism, it achieves rapid automatic flipping of the mold steel between horizontal and vertical clamping postures, avoiding positioning errors caused by manual reclamping and improving the positioning accuracy and efficiency of multi-faceted sawing.

It is suitable for processing mold steel with high surface quality requirements.

[0017] 3. This invention provides a high-precision sawing equipment for mold steel. It employs an independent dual-axis control scheme, where a hydraulic cylinder drives the saw blade for vertical feed and a stepper motor drives the saw frame for horizontal feed. This allows for precise adjustment of the sawing depth and stroke. Combined with a servo motor-driven main sawing motion, all three axes can be independently controlled, meeting the combined requirements of different sawing process parameters for mold steel. Through the material discharge trough at the bottom of the collection box, a detachable drawer, and the suction from the negative pressure fan in the power distribution box via an extraction pipe, automatic settling and centralized collection of sawn metal chips are achieved, preventing chip accumulation in the sawing area from affecting the cutting effect.

[0026] A water pump 12 is fixedly connected to the fixed plate 9, and a water pipe 13 is fixedly connected to the input end of the water pump 12. A water tank 18 is fixedly connected to the frame 1.

A fixed block 11 is fixedly connected to the output end of the electric push rod 10. The top of the fixed block 11 is fixedly connected to the bottom of the fixed plate 9.

[0028] Example 2: Please see Figure 1-10 As shown, based on Embodiment 1, the present invention provides a technical solution: the sawing mechanism 5 includes a sawing frame 501 and a second belt 509. A hydraulic cylinder 502 is fixedly connected to the top of the sawing frame 501, and a connecting seat 503 is fixedly connected to the top of the hydraulic cylinder 502. The outer wall of the connecting seat 503 is slidably connected to the inner wall of the sawing frame 501. A 504 is fixedly connected to the front side wall of the connecting seat 503, and a mounting seat 505 is fixedly connected to the front side wall of the 504. A servo motor 506 is fixedly connected to the mounting seat 505. A connecting shaft is rotatably connected to the inner wall of the mounting seat 505, and a second drive wheel 507 is fixedly connected to the outer wall of the connecting shaft. The servo motor 506... The output end is connected to the connecting shaft of the second drive wheel 507. The inner wall of the mounting base 505 is rotatably connected to the drive shaft, which is located below the connecting shaft. The outer wall of the drive shaft is fixedly connected to the driven wheel 508. The driven wheel 508 and the second drive wheel 507 are connected by a belt 509. The left end of the drive shaft is fixedly connected to the saw blade 510. The hydraulic cylinder 502 drives the connecting base 503 to slide up and down along the saw frame 501, thereby driving the mounting base 505 and the saw blade 510 to rise and fall, realizing precise control of the sawing feed. The servo motor 506 transmits power to the saw blade 510 through the belt 509 to ensure the stability and adjustability of the sawing speed.

[0029] A connecting block 512 is fixedly connected to the left side wall of the sawing frame 501. Fixed seats 515 are symmetrically connected to the support 6. A screw 516 is rotatably connected between the two fixed seats 515. A stepper motor 514 is fixedly connected to the support 6. The output end of the stepper motor 514 is fixedly connected to the rear end of the screw 516. A sliding seat 513 is fixedly connected to the outer wall of the connecting block 512. The inner wall of the sliding seat 513 is threadedly connected to the outer wall of the screw 516. A protective cover 511 is fixedly connected to the right side wall of the mounting base 505. 511 is located outside the drive wheel 507 and driven wheel 508. An isolation cover 20 is fixedly connected to the frame 1. The stepper motor 514 drives the screw 516 to rotate. Through the threaded engagement between the sliding seat 513 and the screw 516, the sawing frame 501 is driven to slide back and forth along the support 6, realizing the automatic feeding of the saw blade 510 in the horizontal direction, which meets the sawing stroke requirements of different lengths of mold steel. The protective cover 511 and the isolation cover 20 isolate the high-speed rotating belt drive part from the outside, preventing the operator from accidentally touching it and causing injury.

[0030] In this embodiment, the hydraulic cylinder 502 drives the connecting seat 503 to slide vertically along the sawing frame 501, and the stepper motor 514 drives the screw 516 to rotate, causing the sawing frame 501 to slide horizontally. This achieves independent and precise feeding of the saw blade 510 in both vertical and horizontal directions, which can meet the sawing requirements of different depths and positions of mold steel. The servo motor 506 drives the saw blade 510 to rotate via belt 2 509, ensuring the stability and speed consistency of the main sawing motion and improving the quality of the saw cut surface. The dual protection design of the protective cover 511 and the isolation cover 20 effectively isolates the high-speed rotating transmission components from the sawing area, avoiding safety hazards caused by flying chips and accidental contact by personnel.

[0031] Working principle: During use, the mold steel to be sawed is placed on the horizontal fixture base plate 305, so that the mold steel is between the two limit seats 307. The cylinder 308 is started to push the auxiliary clamping block 309 to move towards the mold steel. At the same time, the compressed spring 312 pushes the buffer clamping block 313 and the rubber pad clamping PU block 314 to press against the upper surface of the mold steel, so as to fix the mold steel in a horizontal position. During processing, the drive motor 401 is started, which drives the driven wheel 404 and the rotating shaft 303 to rotate 90° through the belt 405. The rotating plate 304 is flipped accordingly, so that the fixture base plate 305, which was originally in a horizontal position, is flipped to a vertical position, and the other fixture base plate 305 is rotated to a horizontal position, so as to realize the rapid switching of the mold steel's position. The limit buffer rod 316 buffers and limits the rotating plate 304 when it is flipped to the right position to prevent overshoot. This method can process two pieces of mold steel at one time, which greatly improves the processing efficiency.

[0032] During sawing, the servo motor 506 is started, driving the saw blade 510 to rotate at high speed via belt 509; the stepper motor 514 is started, driving the screw 516 to rotate, which in turn drives the saw frame 501 to move horizontally along the support 6 to the sawing starting position via the sliding seat 513; the hydraulic cylinder 502 is started, pushing the connecting seat 503 to slide downwards along the saw frame 501, so that the saw blade 510 gradually contacts the mold steel surface and performs sawing feed; during sawing, the air pump 16 is started to supply air to the vortex tube cooler 15. Air is supplied, and the vortex tube cooler 15 generates a low-temperature cold airflow that is sprayed toward the sawing area. At the same time, the water pump 12 is started to spray the coolant in the water tank 18 onto the sawing area through the adjusting nozzle 14, so as to achieve dual cooling of air and liquid and prevent the saw blade 510 from overheating. The sawing debris is sucked into the drawer 8 through the feeding trough 701 and collected under the action of the negative pressure fan. During the processing, the fixed plate 9 can be moved back and forth by the electric push rod 10 so that the adjusting nozzle 14 is always aligned with the sawing position to ensure the cooling effect.
