Description

Technical Field

[0001] This application relates to the field of swing beam shearing machine technology, and in particular to a blade gap adjustment mechanism for a hydraulic swing beam shearing machine. Background Technology

[0002] When using a shearing machine, the gap between the upper and lower blades must be adjusted according to the shearing strength and thickness of the metal sheet being sheared. This gap must be kept uniform; the thicker the metal sheet and the higher the shearing strength, the larger the gap between the upper and lower blades should be. Therefore, the blade gap needs to be adjusted based on the specific shearing conditions.

[0003] A search revealed that patent document CN222036994U discloses a blade gap adjustment mechanism for a hydraulic swing beam shearing machine. The mechanism includes an adjustment seat with a transmission screw mounted on it via bearings. The screw is driven to rotate by a drive motor mounted on the adjustment seat. A blade holder is threadedly connected to the transmission screw and movably connected to a guide rod mounted on the inner wall of the adjustment seat. An upper blade is mounted on the blade holder. This invention solves the problem that existing blade gap adjustments often require manual adjustment by the operator, resulting in large adjustment errors and inconvenience. This new mechanism offers convenient blade gap adjustment, minimizes adjustment errors, and allows for easy installation and removal of the upper blade, enabling replacement and maintenance as needed.

[0004] In practical use, it was found that the existing device lacks an automatic lubrication design when adjusting the blade gap. As a result, the lubrication of transmission components (such as the thread surface of the lead screw and the meshing part of the bevel gear) needs to be performed manually and periodically. This can easily lead to increased wear of components due to untimely lubrication, causing problems such as adjustment jamming and gap drift. In severe cases, it can even cause mechanical jamming. Therefore, we have proposed a blade gap adjustment mechanism for a hydraulic swing beam shearing machine to solve the above problems. Utility Model Content

[0038] Specifically, the gear mechanism includes two bevel gears 504. The screw 102 and the bottom of the rotating shaft 501 are both fixedly fitted with bevel gears 504. The bevel gears 504 are located on the right side of the slide block 2, and the two bevel gears 504 mesh with each other.

[0039] Specifically, the jacking mechanism includes an eccentric wheel 502 and a top block 503. An eccentric wheel 502 is fixedly sleeved on the rotating shaft 501. The eccentric wheel 502 is located inside the function box 5. A top block 503 is fixedly installed on the right side of the push plate 6. The eccentric wheel 502 and the top block 503 are compatible.

[0040] Specifically, a spring 601 is fixedly installed on the left side of the push plate 6, and the left end of the spring 601 is fixedly connected to the inner wall of the left side of the function box 5.

[0041] Specifically, the piston mechanism includes a piston plate 401 and a piston rod 402. The piston plate 401 is slidably installed inside the piston cylinder 4. The same piston rod 402 is fixedly installed on the right side of the piston plate 401 and the left side of the push plate 6. The piston rod 402 is located below the spring 601.

[0042] Specifically, the oil reservoir 3 and the piston cylinder 4 are connected by the same oil inlet pipe 301. The piston cylinder 4 is connected by an oil delivery pipe 302 at the bottom. The oil delivery pipe 302 is located on the left side of the piston plate 401. The bottom end of the oil delivery pipe 302 passes through the top inner wall of the adjusting seat 1. Both the oil delivery pipe 302 and the oil inlet pipe 301 are equipped with a one-way valve. The piston cylinder 4 is connected by a vent pipe at the top. The vent pipe is located on the right side of the piston plate 401.

[0043] Specifically, the sliding mechanism includes a slider 602 and a groove. The top and bottom of the push plate 6 are both provided with sliders 602, and the top and bottom inner walls of the function box 5 are both provided with grooves. The sliders 602 are slidably connected to the corresponding grooves.

[0044] Specifically, the lubrication mechanism includes an atomizer 7 and a fuel injector 701. The atomizer 7 is installed on the inner wall of the top of the adjusting seat 1. The atomizer 7 is located on the left side of the rotating shaft 501. The fuel injector 701 is installed at the bottom of the atomizer 7. The fuel injector 701 is adapted to the lead screw 102 and the bevel gear 504. The top of the atomizer 7 is fixedly connected to the bottom of the oil supply pipe 302.

[0045] In this application, when adjusting the blade spacing, the output shaft of the motor 101 can drive the lead screw 102 to rotate precisely within the adjusting seat 1. Since the slide 2 is threadedly connected to the lead screw 102 and slidably mounted on the fixed rod 8, the slide 2 can slide smoothly along the fixed rod 8. By changing the lateral position of the shearing blade 202 at the bottom of the slide 2, the blade spacing can be precisely adjusted to meet the shearing requirements of plates of different thicknesses. When the lead screw 102 rotates, the bevel gear 504 at its right end can mesh with the bevel gear 504 at the bottom of the rotating shaft 501. The rotating shaft 501 rotates synchronously, and the eccentric wheel 502 on the rotating shaft 501 rotates with it. When the protruding end of the eccentric wheel 502 contacts the top block 503 on the right side of the push plate 6, it pushes the push plate 6 to slide to the left under the guidance of the slider 602 and the slide groove, while compressing the spring 601 to store elastic potential energy. The push plate 6 drives the piston plate 401 to move to the left in the piston cylinder 4 through the piston rod 402. At this time, the one-way valve in the oil inlet pipe 301 is closed, the volume of the left chamber of the piston cylinder 4 decreases, and the lubricating oil is pressurized and delivered to the atomizer 7 through the oil delivery pipe 302. The oil injector 701 atomizes the oil into a fine mist, which is evenly sprayed onto key transmission parts such as the thread surface of the lead screw 102 and the meshing point of the bevel gear 504. This achieves the formation of a continuous oil film, reduces the coefficient of friction, minimizes component wear, and ensures smooth transmission. When the eccentric wheel 502 rotates until its protruding end disengages from the top block 503, the spring 601 releases its elastic potential energy, pushing the push plate 6 to the right for reset. The piston plate 401 moves to the right with the piston rod 402, creating a negative pressure in the left chamber of the piston cylinder 4. Under the action of the air pressure difference, the lubricating oil in the oil reservoir 3 flows through the oil inlet pipe 301. The valve opens to supply oil to the left side of the piston cylinder 4, while the right side of the piston plate 401 is connected to the atmosphere through the vent pipe. The balanced air pressure ensures that the piston plate 401 returns to its original position smoothly. Through the continuous rotation of the eccentric wheel 502 and the reciprocating return of the spring 601, the piston plate 401 can perform periodic pumping and pressing actions. This allows for the automatic extraction, pressurization, atomization, and spraying of lubricating oil while adjusting the blade gap. This synchronizes the lubrication process with the gap adjustment, ensuring long-term lubrication of the transmission components and avoiding the lag and unevenness of manual lubrication.
