This utility model discloses a sawing device for flat steel processing, relating to the field of flat steel processing technology. It includes a worktable with a fixed frame fixedly connected to its upper end. Multiple rollers are rotatably connected within the fixed frame. A lifting frame is located above the fixed frame. Two connecting frames are symmetrically fixed on both sides of the front end of the lifting frame. A movable column is slidably connected to the connecting frames, and a sliding cylinder is slidably connected to the lower end of the movable column. A spring is fixedly connected between the lower end of the movable column and the bottom wall of the sliding cylinder. A mounting plate is fixedly connected to the lower end of the sliding cylinder, and a pressure plate is rotatably connected to the lower end of the mounting plate.

As the lifting frame continues to descend, it causes the spring to compress and deform, causing the pressure plate to press tightly against the flat steel, preventing the flat steel from shifting due to vibration during sawing.

Description

Technical Field

[0001] This utility model relates to the field of flat steel processing technology, and in particular to a sawing device for flat steel processing. Background Technology

[0002] Flat steel is a flat steel material with a rectangular cross-section. The core value of flat steel sawing equipment in coal mines lies in its precision, efficiency, and strong environmental adaptability. Flat steel is mainly used in coal mines for support structures, and it needs to be cut into sections and then welded into specific arc segments.

[0003] A search revealed Chinese patent publication number CN222919685U, which discloses a flat steel cutting device with guide grooves. This patent uses a first motor to drive a transmission rod to rotate, which in turn drives a second bevel gear to rotate a first bevel gear, thus rotating a guide wheel on one side. This causes the flat steel between the two guide wheels to move. During cutting, the second motor drives the gears to rotate via a rotating rod, which in turn moves the racks on both sides, thereby moving the guide wheels on both sides. However, this device has certain problems: the guide wheels on both sides only guide the flat steel from both sides, and cannot fix the flat steel in multiple directions before sawing. The vibration generated by the external force during sawing may cause the flat steel to shift. Utility Model Content

[0004] The purpose of this invention is to provide a sawing device for processing flat steel in order to solve the above-mentioned problems.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] A sawing device for processing flat steel includes a worktable, a fixed frame fixedly connected to the upper end of the worktable, multiple rollers rotatably connected inside the fixed frame, a lifting frame above the fixed frame, and a pressing mechanism on the lifting frame.

[0007] The pressing mechanism includes two connecting frames, which are symmetrically fixed on both sides of the front end of the lifting frame. A sawing assembly is provided between the two connecting frames. A movable column is slidably connected to the connecting frame. A sliding cylinder is slidably connected to the lower end of the movable column. A spring is fixedly connected between the lower end of the movable column and the bottom wall of the sliding cylinder. A mounting plate is fixedly connected to the lower end of the sliding cylinder. A pressing plate is rotatably connected to the lower end of the mounting plate. The pressing plate is a semi-circular shape with an opening facing downwards. Anti-slip protrusions are fixedly connected to both ends of the pressing plate.

[0008] Preferably, the sawing assembly includes a movable block, which is slidably connected to the lower end of the lifting frame. A sawing motor is fixedly installed at the front end of the movable block, and a saw blade is fixedly connected to the output shaft of the sawing motor.

[0009] Preferably, an auxiliary lead screw is rotatably connected inside the lifting frame, and the auxiliary lead screw is threadedly connected to the moving block. A power motor is fixedly installed on one side of the lifting frame, and the power motor is fixedly connected to the auxiliary lead screw.

Therefore, they should not be construed as limitations on this utility model.

[0025] The present invention will be further described below with reference to the accompanying drawings:

[0026] like Figures 1-5 As shown, a sawing device for processing flat steel includes a workbench 101, a fixed frame 102 is fixedly connected to the upper end of the workbench 101, a plurality of rollers are rotatably connected inside the fixed frame 102, a lifting frame 302 is provided above the fixed frame 102, and a pressing mechanism is provided on the lifting frame 302.

[0027] The pressing mechanism includes two connecting frames 401, which are symmetrically fixed on both sides of the front end of the lifting frame 302. A sawing assembly is provided between the two connecting frames 401. A moving column 402 is slidably connected to the connecting frame 401. A sliding cylinder 403 is slidably connected to the lower end of the moving column 402. A spring is fixedly connected between the lower end of the moving column 402 and the bottom wall of the sliding cylinder 403. A mounting plate 404 is fixedly connected to the lower end of the sliding cylinder 403. A pressing plate 405 is rotatably connected to the lower end of the mounting plate 404. The pressing plate 405 is a semi-circular shape with an opening facing downwards. Anti-slip protrusions are fixedly connected to both ends of the pressing plate 405. In use, the moving column 402 is pushed to make the moving column... 402 moves to a suitable position on the connecting frame 401, then fixes the moving column 402, and then drives the sawing assembly to descend through the lifting frame 302, causing the pressure plate 405 and the mounting plate 404 to rotate. The end of the pressure plate 405 near the flat steel abuts against the upper surface of the flat steel, and the end of the pressure plate 405 away from the flat steel abuts against the side wall of the flat steel, thereby fixing the position of the flat steel. As the lifting frame 302 continues to descend, the sliding cylinder 403 slides against the moving column 402, causing the spring to compress and deform, so that the pressure plate 405 presses tightly against the flat steel. At the same time, the sawing assembly saws the flat steel, preventing the flat steel from shifting due to force vibration during the sawing process.

[0028] The sawing assembly includes a moving block 501, which is slidably connected to the lower end of the lifting frame 302. A sawing motor 502 is fixedly installed at the front end of the moving block 501, and a saw blade 503 is fixedly connected to the output shaft of the sawing motor 502.

[0029] An auxiliary lead screw is rotatably connected inside the lifting frame 302. The auxiliary lead screw is threadedly connected to the moving block 501. A power motor is fixedly installed on one side of the lifting frame 302. The power motor is fixedly connected to the auxiliary lead screw. The power motor drives the auxiliary lead screw to rotate, so that the moving block 501 and the auxiliary lead screw are threadedly engaged, causing the moving block 501 to slide inside the lifting frame 302. At the same time, the sawing motor 502 drives the saw blade 503 to rotate, so that the saw blade 503 cuts the flat steel.

[0030] A support frame 103 is fixedly connected to the upper end of the workbench 101. A hydraulic cylinder 301 is fixedly installed on the upper end of the support frame 103. The output shaft of the hydraulic cylinder 301 is fixedly connected to the lifting frame 302. Multiple guide columns 303 are fixedly connected to the upper end of the lifting frame 302. The hydraulic cylinder 301 drives the lifting frame 302 to descend, causing the multiple guide columns 303 to slide against the support frame 103.

[0031] A scale is fixedly connected to the front end of the lifting frame 302. A pointer is fixedly connected to the side of the moving column 402 near the scale. A locking knob 7 is threadedly connected to the upper end of the moving column 402. The positions of the two moving columns 402 are adjusted by the pointer and the scale so that the two moving columns 402 correspond to the two sides of the flat steel. Then, the locking knob 7 is rotated so that the locking knob 7 engages with the threaded upper end of the moving column 402, causing the locking knob 7 to approach the connecting frame 401 and abut against the connecting frame 401.

[0032] The fixed frame 102 has symmetrical movable frames 202 slidably connected to both sides, and a movable screw 201 is rotatably connected to one side of the fixed frame 102. The movable screw 201 is threadedly connected to the movable frame 202.

[0033] The movable frame 202 is fixed with symmetrical auxiliary plates 601 at the front and rear. Symmetrical clamping plates 602 are slidably connected to both sides of the auxiliary plates 601. An electric push rod is fixedly installed between the clamping plate 602 on the same side and the movable frame 202. The electric push rod drives the clamping plates 602 on both sides to approach the flat steel for clamping. Then, the moving screw 201 rotates and drives the movable frame 202 to move on the moving screw 201, so that the clamping plate 602 drives the flat steel and the roller to roll and move to the bottom of the lifting frame 302.

[0034] Working principle: During use, the flat steel is placed on 102, making it abut against the roller. Then, an electric push rod drives the clamping plates 602 on both sides to clamp the flat steel. Subsequently, the moving screw 201 rotates, driving the moving frame 202 to move along the screw, causing the clamping plates 602 to roll along the flat steel and roller until they are below the lifting frame 302. The positions of the two moving columns 402 are then adjusted using a pointer and scale, pushing them to align with the sides of the flat steel. Next, the locking knob 7 is rotated, engaging with the threaded upper end of the moving column 402, causing it to approach and abut against the connecting frame 401. The hydraulic cylinder 301 drives the lifting frame 302 to descend, causing the multiple guide columns 303 to contact the support frame 103. When slippage occurs, the sawing assembly is driven to descend via the lifting frame 302, causing the pressure plate 405 and the mounting plate 404 to rotate. The end of the pressure plate 405 near the flat steel abuts against the upper surface of the flat steel, and the end of the pressure plate 405 away from the flat steel abuts against the side wall of the flat steel, thereby fixing the position of the flat steel. As the lifting frame 302 continues to descend, the sliding cylinder 403 and the moving column 402 slide, causing the spring to compress and deform, so that the pressure plate 405 presses tightly against the flat steel. The power motor drives the auxiliary lead screw to rotate, so that the moving block 501 and the auxiliary lead screw are threaded together, causing the moving block 501 to slide within the lifting frame 302. At the same time, the sawing motor 502 drives the saw blade 503 to rotate, so that the saw blade 503 saws the flat steel, preventing the flat steel from shifting due to force vibration during the sawing process.
