Description

Technical Field

[0001] This utility model relates to the fields of steel rolling technology and steel rolling equipment technology, and in particular to a quick-change flying shear blade fixing device. Background Technology

[0002] Flying shears are core cutting equipment in metal rolling, sheet, and strip processing production lines. They are mainly used to cut, segment, or cut the head and tail of metal materials in continuous high-speed motion to ensure that subsequent processing can obtain blanks of uniform length. When changing the blades of existing flying shear machines, the blades are mostly fixed by manual bolts or ordinary mechanical chucks. Changing the blades requires operating the bolts one by one or repeatedly adjusting the chucks, which takes 10-20 minutes each time, greatly increasing the downtime of the production line. In addition, when lubricating the blades, the oil is often applied manually, which is inefficient and prone to missing the coating.

[0003] The purpose of this utility model is to provide a quick-change flying shear blade fixing device to solve the technical problem that when changing the blade, the shear blade is mostly fixed by manual bolts or ordinary mechanical chucks. Changing the blade requires operating the bolts one by one or repeatedly adjusting the chucks, which takes 10-20 minutes each time, greatly increasing the downtime of the production line. Utility Model Content

[0004] This utility model provides a quick-change flying shear blade fixing device, which solves the technical problem that when changing the blade, it is mostly necessary to manually fix the blade with bolts or ordinary mechanical chucks. Changing the blade requires operating the bolts one by one or repeatedly adjusting the chucks, which takes 10-20 minutes each time and greatly increases the downtime of the production line.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A quick-change flying shear blade fixing device includes a fixing component and a spraying component mounted on a fixing frame; The fixing component includes two sets of support frames, and fixed anti-slip blocks are fixedly connected to the outer side of both sets of support frames. Sliding anti-slip blocks are slidably embedded inside the two sets of support frames. An anti-slip frame is clamped in the gap between the fixed anti-slip block and the sliding anti-slip block, and a blade is connected to the lower end of the anti-slip frame. The spraying assembly includes a liquid storage tank, and a liquid delivery pipe is connected to the lower part of the liquid storage tank; A support block is fixedly connected to the lower side wall of the fixed frame, and a support rod is fixedly connected between the two support blocks. One end of the air supply pipe passes through the support rod and is installed inside the cylinder. The other end of the air supply pipe is fixedly connected to a liquid outlet, and a pressure valve is installed inside the air supply pipe. The cylinder is connected to the air pump, and a power block is fixedly connected to the output end of the cylinder. The power block is connected to the sliding anti-blocking block through two sets of push plates.

[0006] Furthermore, the power block has a power column rotatably embedded inside, and two sets of push plates are rotatably sleeved on the outer surface of the power column. The lower ends of the two sets of push plates are rotatably embedded with connecting columns, and the two sets of connecting columns are rotatably embedded inside the sliding anti-blocking block.

[0007] Furthermore, an air pump is installed inside the fixing frame, and the air pump is connected to an air inlet pipe. The end of the air inlet pipe away from the air pump is located inside the cylinder.

[0008] Furthermore, the end of the liquid delivery pipe furthest from the liquid storage tank is located inside the gas delivery pipe.

[0009] Furthermore, an inlet pipe is fixedly connected to the top of the outer surface of the liquid storage tank.

[0010] Furthermore, the liquid outlet head is configured as a nozzle with an inclined angle facing the contact direction between the blade and the workpiece.

[0011] The beneficial effects of this utility model are as follows: Compared with the prior art, the beneficial effects achieved by this utility model are: 1. When the blade needs to be replaced, place the anti-slip bracket in the gap between the sliding anti-slip block and the fixed anti-slip block. By activating the cylinder, the output end of the cylinder pushes the power block outward. The movement of the power block drives multiple push plates to unfold to both sides via the power column. The push plates are connected to the sliding anti-slip block via connecting columns, and the sliding anti-slip block is slidably embedded inside the support frame. The push from the output end of the cylinder drives the two sets of sliding anti-slip blocks to move to both sides. Both the sliding and fixed anti-slip blocks have anti-slip coatings on their surfaces. The blade is fixed by the clamping of the sliding and fixed anti-slip blocks. During use, the air pump continuously draws air, which is delivered to the cylinder through the air inlet pipe, so that the output end of the cylinder always maintains thrust, thereby stabilizing the clamping of the sliding and fixed anti-slip blocks. Through the above technical solution, the blade replacement efficiency is improved, the downtime is shortened, and the air pump ensures a constant clamping force, preventing the blade from loosening during high-speed shearing and ensuring the stability of continuous production.

[0012] 2. Add lubricating oil to the storage tank through the inlet pipe. The lubricating oil is then drawn out by the pump inside the storage tank and delivered to the air supply pipe through the delivery pipe. The lubricating oil is then sprayed out through the outlet head, which has a certain tilt angle facing the contact direction between the blade and the object. The cylinder is connected to the outlet head through the air supply pipe, and the air supply pipe is equipped with a pressure valve. When the gas drawn in by the pump into the cylinder is sufficient and exceeds the threshold of the pressure valve, the gas is discharged through the pressure valve. The gas pressurizes and sprays the lubricating oil delivered through the delivery pipe. The gas pressurization makes the lubricating oil in a high-pressure spray state, which can accurately cover the contact point between the blade shearing edge and the blade holder, avoiding the problems of local missed coating and uneven coating caused by manual oiling, reducing the friction coefficient between the blade and the material, and extending the service life of the blade.

A support block 103 is fixedly connected to one side of the outer surface of the fixing frame 1, and a support rod 104 is fixedly connected to one side of the outer surface of the support block 103. An air delivery pipe 702 is provided inside the support rod 104, and a liquid outlet head 7 is fixedly connected to one end of the outer surface of the air delivery pipe 702. A pressure valve 703 is provided inside the air delivery pipe 702.

[0022] Specifically, the power block 201 has a power column 202 rotatably embedded inside, and two sets of push plates 203 are rotatably sleeved on the outer surface of the power column 202. The two sets of push plates 203 have connecting columns 204 rotatably embedded inside, and the two sets of connecting columns 204 are rotatably embedded inside the sliding anti-blocking block 3.

[0023] Through the above technical solution, the output end of the cylinder 2 pushes the power block 201 to move outward. The movement of the power block 201 drives multiple push plates 203 to unfold to both sides through the power column 202. The push plates 203 are connected to the sliding anti-slip blocks 3 through the connecting column 204. The sliding anti-slip blocks 3 are slidably embedded in the support frame 101. The push from the output end of the cylinder 2 drives the two sets of sliding anti-slip blocks 3 to move to both sides.

[0024] Specifically, the mounting bracket 1 is equipped with an air pump 5, and the air pump 5 is equipped with an air inlet pipe 501. The end of the air inlet pipe 501 away from the air pump 5 is located inside the cylinder 2.

[0025] Through the above technical solution, the gas is continuously pumped by the air pump 5 and transported to the inside of the cylinder 2 through the air inlet pipe 501, so that the output end of the cylinder 2 always maintains thrust.

[0026] Specifically, the end of the liquid delivery pipe 701 away from the liquid storage tank 6 is located inside the air delivery pipe 702, and the top of the outer surface of the liquid storage tank 6 is fixedly connected to the liquid inlet pipe 601.

[0027] Through the above technical solution, lubricating oil is delivered to the air supply pipe 702 through the liquid delivery pipe 701, and then sprayed out through the liquid outlet head 7.

[0028] Specifically, the end of the air supply pipe 702 furthest from the liquid outlet head 7 is located inside the cylinder 2.

[0029] With the above technical solution, when the gas drawn in by the vacuum pump 5 is already a large amount inside the cylinder 2 and exceeds the threshold of the pressure valve 703, the gas is discharged through the pressure valve 703, and the gas is used to pressurize and spray the lubricating oil delivered by the liquid delivery pipe 701.

[0030] Specifically, an anti-slip bracket 401 is provided on one side of the outer surface of both sets of sliding anti-slip blocks 3, and a blade 4 is fixedly connected to one side of the outer surface of the anti-slip bracket 401.

[0031] The blade 4 is fixed by the clamping of the sliding anti-blocking block 3 and the fixed anti-blocking block 102 through the above technical solution.

[0032] When using the device, to replace the blade 4, place the anti-slip bracket 401 in the gap between the multiple sliding anti-slip blocks 3 and the fixed anti-slip block 102. Activate the cylinder 2, which pushes the power block 201 outwards. The movement of the power block 201, via the power column 202, causes multiple push plates 203 to expand to both sides. The push plates 203 are connected to the sliding anti-slip blocks 3 via connecting columns 204, and the sliding anti-slip blocks 3 are slidably embedded inside the support frame 101. The push from the output of the cylinder 2 causes the two sets of sliding anti-slip blocks 3 to move to both sides. Both the sliding anti-slip block 3 and the fixed anti-slip block 102 have anti-slip coatings. The blade 4 is fixed by the clamping of the sliding anti-slip block 3 and the fixed anti-slip block 102. During use, the air pump 5 continuously draws air, and the gas is delivered to the cylinder 2 through the air inlet pipe 501, so that the output end of the cylinder 2 always maintains thrust, thereby stabilizing the clamping of the sliding anti-slip block 3 and the fixed anti-slip block 102. Through the above technical solution, the replacement efficiency of the blade 4 is improved, the downtime is shortened, and the air pump 5 ensures that the clamping force is constant, preventing the blade 4 from loosening during high-speed shearing and ensuring the stability of continuous production. Workers add lubricating oil to the storage tank 6 through the inlet pipe 601. The lubricating oil is then drawn out by a pump inside the storage tank 6 and delivered to the air supply pipe 702 through the delivery pipe 701. Subsequently, it is sprayed out through the outlet head 7, which has a certain tilt angle facing the contact direction between the blade 4 and the object. The cylinder 2 is connected to the outlet head 7 through the air supply pipe 702, and a pressure valve 703 is installed inside the air supply pipe 702. When the gas drawn in by the pump 5 has reached a certain amount inside the cylinder 2 and exceeds the threshold of the pressure valve 703, the gas is discharged through the pressure valve 703. The gas pressurizes and sprays the lubricating oil delivered by the delivery pipe 701. Through the above technical solution, the lubricating oil is sprayed under high pressure by gas pressurization, which can accurately cover the contact point between the cutting edge of the blade 4 and the blade holder, avoiding the problems of local missed coating and uneven coating caused by manual oiling, reducing the friction coefficient between the blade 4 and the material, and extending the service life of the blade 4.
