Technical Field
[0001] This utility model relates to the field of steel processing technology, specifically to an automatic hydraulic steel cutting machine. Background Technology
[0002] During use, steel needs to be cut into specific lengths according to the design drawings. Automatic hydraulic steel cutting machines are industrial equipment used for efficient cutting of steel. They are widely used in metal processing, construction, machinery manufacturing and other industries. They provide powerful force through a hydraulic system and can quickly and accurately cut steel of various specifications.
[0003] Existing steel cutting equipment generally uses mechanical gears and crankshafts, equipped with a high-power motor and a heavy flywheel, to break the material by inertia, thereby achieving the cutting of steel.
[0004] Existing steel cutting equipment, while capable of using mechanical gears and crankshafts, along with a high-power motor and a heavy flywheel, to cut materials by inertia, suffers from significant inertial impact forces. This leads to rapid damage to gears, bushings, main shafts, and crankshafts, as well as other components that are easily damaged and difficult to disassemble and repair, resulting in excessive production costs. Furthermore, the mechanical transmission is limited, failing to protect the cut surface, and the cut products exhibit significant deformation and severe horseshoe-shaped edges, rendering them unusable in subsequent processes. Additionally, the current flywheel inertia principle generates excessive noise during operation, severely exceeding noise standards in the production workshop and causing occupational diseases for many operators. Therefore, we propose an automatic hydraulic steel cutting machine. Utility Model Content

Detailed Implementation
[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Please see Figure 1-6 This embodiment provides a technical solution: an automatic hydraulic steel cutting machine, including a feeding platform 1 and a cutting mechanism 3;
[0025] Cutting mechanism 3 includes a cutting port 31, a shearing cylinder 32, a cutting blade 33, an auxiliary cylinder 37, and a limiting seat. The cutting port 31 is located on the front side of the left end of the loading platform 1. The shearing cylinder 32 is located on the rear side of the left end of the loading platform 1. The cutting blade 33 is located at the front end of the telescopic end of the shearing cylinder 32 and is inside the cutting port 31. An inclined chute 19 is located on the front side of the bottom wall of the cutting port 31. The auxiliary cylinder 37 is located on the left side of the front end of the loading platform 1. A limiting seat 38 is located at the rear end of the telescopic end of the auxiliary cylinder 37. The limiting seat 38 corresponds to the front and rear positions of the cutting blade 33. The cutting mechanism 3 also... The system includes a mounting frame 34, a length-fixing cylinder 35, and an adjusting plate 36. The mounting frame 34 is located on the upper left side of the loading platform 1. The length-fixing cylinder 35 is located on the lower left side of the mounting frame 34. The adjusting plate 36 is located on the right end of the telescopic end of the length-fixing cylinder 35, to the left of the cutting tool 33. Compressed air enters the length-fixing cylinder 35, pushing the piston inside the cylinder downward. The downward movement of the piston compresses the hydraulic oil, increasing its pressure. The high-pressure hydraulic oil is output through the outlet, causing the telescopic end of the length-fixing cylinder 35 to move to the right. The telescopic end of the length-fixing cylinder 35 then moves the adjusting plate 36. Move 6 to the right to control the length of the cut steel. When the left end of the steel contacts the right end of the adjusting plate 36, the steel stops moving due to the obstruction of the adjusting plate 36. The flow of compressed air is controlled by an external solenoid valve, causing the shearing cylinder 32 to operate. At this time, compressed air enters the shearing cylinder 32, pushing the piston inside the shearing cylinder 32 forward. The forward movement of the piston compresses the hydraulic oil, increasing its pressure. The high-pressure hydraulic oil is output through the outlet, used to move the extension end of the shearing cylinder 32 forward. Simultaneously, the extension end of the auxiliary cylinder 37 extends, and the auxiliary cylinder... 37 will drive the limit seat 38 to move backward, eventually bringing the limit seat 38 into contact with the outer arc surface of the steel, thus supporting the steel. The telescopic end of the shearing cylinder 32 will drive the cutting tool 33 to move forward, and then the cutting tool 33 will shear the steel. The hydraulic system shearing principle is adopted, which can effectively reduce noise (the noise can be controlled below 60 decibels), reduce the risk of occupational diseases for operators, and replace the traditional shearing method based on inertia principle. It also reduces damage to the equipment and lowers costs. The cut surface of the finished product is flat and burr-free, further improving the quality of the finished product.
[0026] It also includes a control switch group 2, which is located outside the loading platform 1. The input terminal of the loading platform 1 is electrically connected to an external power supply and can regulate the electrical components inside the equipment.
[0027] Among them: a cooling fan 4 is installed on the rear side of the upper end of the feeding platform 1. The cooling fan 4 is located on the right side of the fixed length cylinder 35. The input end of the cooling fan 4 is electrically connected to the output end of the control switch group 2. The cooling fan 4 can cool down the fixed length cylinder 35.
[0028] The automatic hydraulic steel cutting machine is equipped with a conveyor frame 9 on the right side of the loading platform 1. Guide plates 10 are installed on the upper side of the rear wall of the conveyor frame 9. Baffle plates 11 are installed on the front side of the upper ends of the four guide plates 10. An electric push rod 12 is installed in the middle of the bottom wall of the conveyor frame 9. A fixing plate 13 is installed at the upper end of the telescopic end of the electric push rod 12. A push plate 14 is installed in the middle of the upper end of the fixing plate 13. Limit plates 15 are installed on the upper side of the front wall of the loading platform 1. A feeding wheel 16 is rotatably connected to the middle of the front wall of the loading platform 1. The feeding wheel 16 is located between the front end of the vertically adjacent baffle plates 11 and the rear end of the limit plates 15. The input end of the electric push rod 12 is electrically connected to the output end of the control switch group 2. During the operation of the automatic hydraulic steel cutting machine, the operator first loads the steel in sequence... The steel is placed on the upper part of the guide plate 10. Since the guide plate 10 is inclined, the steel will move forward along the guide plate 10 and finally be blocked by the baffle plate 11. Then, through the control of the control switch group 2, the electric push rod 12 starts to run. The telescopic end of the electric push rod 12 extends, so that the electric push rod 12 drives the push plate 14 to move upward through the fixed plate 13. Then the upper end of the push plate 14 will contact the lower side of the foremost steel. Then the push plate 14 drives the foremost steel to move upward. The baffle plate 11 is also inclined. When the steel moves to the upper side of the baffle plate 11, the steel will move forward along the baffle plate 11 and finally be blocked by the limit plate 15. The blocked steel will fall on the upper side of the outer arc surface of the feeding wheel 16.
[0029] Among them: the front end of the conveyor frame 9 is equipped with motors 17 respectively. The rear end of the output shafts of the four sets of motors 17 are fixedly connected to the front end of the longitudinally adjacent feeding wheels 16 respectively. The upper side of the front end of the conveyor frame 9 is equipped with a protective cover 18. The motors 17 are all located inside the protective cover 18. The input end of the motors 17 is electrically connected to the output end of the control switch group 2. By controlling the control switch group 2, the motors 17 start to run. The output shafts of the four sets of motors 17 drive the corresponding longitudinal feeding wheels 16 to rotate. During the rotation of the feeding wheels 16, the steel will move to the left.
[0030] The loading platform 1 has two mounting frames 5 on its front side. The lower side of the two mounting frames 5 is rotatably connected to the conveyor wheels 6. The middle of the upper end of the two mounting frames 5 is equipped with a pressing cylinder 20. The lower end of the telescopic end of the pressing cylinder 20 is equipped with a mounting seat 7. The middle of the lower end of the mounting seat 7 is rotatably connected to a guide wheel 8. The guide wheel 8 corresponds to the vertically adjacent conveyor wheels 6. The adjusting plate 36, the two sets of conveyor wheels 6 and the four sets of feeding wheels 16 are all located on the same plane. The flow direction of compressed air is controlled by an external solenoid valve, thereby driving the pressing cylinder 20 to work. At this time, the telescopic end of the pressing cylinder 20 extends, so that the pressing cylinder 20 drives the guide wheel 8 to move downward through the mounting seat 7. Finally, the guide wheel 8 contacts the outer arc surface of the steel, so that the guide wheel 8 limits the steel.
[0031] The working principle of the automatic hydraulic steel cutting machine provided by this utility model is as follows: During the use of the automatic hydraulic steel cutting machine, the operator first places the steel pieces sequentially on the upper end of the guide plate 10. Since the guide plate 10 is inclined, the steel pieces will move forward along the guide plate 10 and finally be blocked by the stop plate 11. Then, through the regulation of the control switch group 2, the electric push rod 12 starts to run, and the telescopic end of the electric push rod 12 extends, thereby causing the electric push rod 12 to drive the push plate 14 to move upward through the fixed plate 13. Then, the upper end of the push plate 14 will contact the lower side of the outer arc surface of the foremost steel piece, and then the push plate 14 will drive the foremost steel piece to move upward. The stop plate 11 is also inclined. When the steel piece moves to the upper side of the stop plate 11, The steel will move forward along the baffle plate 11 and finally be blocked by the limit plate 15. After being blocked, the steel will fall onto the upper side of the outer arc surface of the feeding wheel 16. Then, through the regulation of the control switch group 2, the motor 17 starts to run. The output shafts of the four sets of motors 17 drive the corresponding longitudinal feeding wheels 16 to rotate. The rotation direction of the four sets of motors 17 is the same. During the rotation, the feeding wheel 16 will drive the steel to move to the left, and then continue to move to the left under the guidance of the conveying wheel 6. At the same time, the flow direction of compressed air is controlled by the external solenoid valve, thereby driving the pressing cylinder 20 to work. At this time, the extension end of the pressing cylinder 20 extends, so that the pressing cylinder 20 drives the guide wheel 8 to move downward through the mounting base 7. Finally, the guide wheel 8... The guide wheel 8 contacts the outer arc surface of the steel, thus limiting the movement of the steel. During the movement of the steel, the flow of compressed air is controlled by an external solenoid valve, causing the length-cutting cylinder 35 to operate. At this time, compressed air enters the length-cutting cylinder 35, pushing the piston inside the cylinder 35 downward. The downward movement of the piston compresses the hydraulic oil, increasing the pressure of the hydraulic oil. The high-pressure hydraulic oil is output through the output port, which moves the extension end of the length-cutting cylinder 35 to the right. The extension end of the length-cutting cylinder 35 drives the adjusting plate 36 to move to the right, thereby controlling the length of the cut steel. Subsequently, when the left end of the steel contacts the right end of the adjusting plate 36, the steel stops moving due to the obstruction of the adjusting plate 36. Then, the movement is controlled by the external solenoid valve. The flow of compressed air is controlled, causing the shearing cylinder 32 to operate. Compressed air enters the shearing cylinder 32, pushing the piston inside to move forward. This forward movement of the piston compresses the hydraulic oil, increasing its pressure. The high-pressure hydraulic oil is output through the outlet, propelling the telescopic end of the shearing cylinder 32 forward. This telescopic end of the shearing cylinder 32 then moves the cutting tool 33 forward. Simultaneously, the telescopic end of the auxiliary cylinder 37 extends, causing the limiting seat 38 to move backward. Finally, the limiting seat 38 contacts the outer arc surface of the steel, thus supporting the steel. The cutting tool 33 then shears the steel, and the cut steel falls into the inclined chute 19.The cut steel is then discharged along the inclined chute 19, thus completing the steel cutting process.
[0032] It is worth noting that the cooling fan 4 disclosed in the above embodiments can be ME92252V1-000C-A99, the electric push rod 12 can be DYTFD2000-550 / 45, the motor 17 can be 5IK200A-AF, and the control switch group 2 is provided with control buttons corresponding to the cooling fan 4, the electric push rod 12 and the motor 17 for controlling their switching.
