Technical Field

[0001] This application relates to the field of steel processing technology, and in particular to a flat steel cutting machine. Background Technology

[0002] A flat steel cutting machine is a specialized piece of equipment for processing flat steel. It precisely cuts flat steel to predetermined lengths and specifications, resulting in uniformly sized flat steel products. The basic principle of this machine involves materials science and engineering. First, the required length of the flat steel is determined based on the customer's specific needs or industry standards. Next, the length is measured using precision measuring tools. Then, a suitable cutting process, such as sawing, laser cutting, or plasma cutting, is employed to cut the material to the predetermined dimensions. Finally, the cut flat steel undergoes quality inspection to ensure that its dimensional accuracy and surface quality meet requirements. Throughout the entire process, strict control of the error range is necessary to improve product quality and meet the practical application needs of various industries, including construction and machinery manufacturing.

[0003] In implementing this application, the prior art has at least the following problems, such as the inability of existing flat steel cutting machines to use cooling and cutting simultaneously, resulting in defects such as reduced cutting quality, increased tool wear, and increased safety hazards. Therefore, a flat steel cutting machine is proposed to solve the problems mentioned above. Utility Model Content

[0004] To address the shortcomings of existing technologies, this application provides a flat steel cutting machine with advantages such as high practicality and high production efficiency, solving the problem that flat steel cutting machines cannot simultaneously use cooling and cutting.

[0005] In summary, this application provides the following technical solution: a flat steel cutting machine, comprising a flat steel processing cutting machine, wherein the cutting machine includes a limiting seat, a cutting table, a buffer structure, a mounting frame, a hydraulic telescopic rod, a cutting blade and a material conveying mechanism disposed above the machine base;

[0006] The limiting seat is externally equipped with a cooling device that is linked with the hydraulic telescopic rod. The cooling device includes a water tank, a pump body, a spray pipe, a nozzle, and a linkage connecting arm.

[0007] The pump body includes a pump casing, a piston, a pump rod, a check valve, and a check plate. The pump casing has a pump chamber. The piston slides against the inside of the pump chamber. The pump rod is fixedly installed on the upper surface of the piston, and its top end extends to the outside of the pump casing and is connected and fixed to the outer surface of the linkage connecting arm. The other end of the linkage connecting arm is fixed to the outer surface of the fixed-length cutting blade.

[0008] This application adopts the above-mentioned technical solution, and through the installation of the linkage connecting arm, realizes the linkage between the reciprocating lifting of the cutting blade and the water cooling system, so that cutting and cooling can be carried out simultaneously, reducing waiting time, improving production efficiency, enhancing cutting quality, achieving the advantage of high production efficiency, and solving the problem that flat steel cutting machines cannot use cooling and cutting simultaneously.

[0009] Furthermore, there are two limiting seats, and the two limiting seats are fixedly installed at equal intervals on the upper surface of the machine base. The cutting table is located between the two limiting seats, and the buffer structure is fixedly installed between the machine base and the cutting table.

[0010] The beneficial effect of adopting the above-mentioned further solution is that by installing a buffer structure, the impact generated when the fixed-length cutting blade cuts the flat steel can be buffered, thereby improving the service life of the device.

[0011] Furthermore, the mounting bracket is welded to the upper surface of the two limit seats, the hydraulic telescopic rod is bolted to the upper surface of the mounting bracket, and the output end of the hydraulic telescopic rod passes through its interior and is fixed to the upper surface of the fixed-length cutting blade.

[0013] Furthermore, guide seats are installed on opposite sides of the two limiting seats, and the left and right sides of the fixed-length cutting blade are slidably connected to the two guide seats respectively.

[0014] The beneficial effect of adopting the above-mentioned further solution is that by installing two sets of guide seats, the fixed-length cutting blade is limited, so that the hydraulic telescopic rod can linearly drive the fixed-length cutting blade to move up and down, thereby improving the cutting accuracy of the fixed-length cutting blade.

[0015] Furthermore, a mounting base for fixing the nozzle is fixedly installed on the front of both limiting seats, and several nozzles are fixedly connected to the side of the nozzle near the length cutting blade.

[0017] Furthermore, there are two check valves and two check plates. The two check valves are symmetrical and fixedly connected to the outer surface of opposite sides of the pump casing. The two check plates are elastically hinged and installed inside the two check valves.

[0018] The beneficial effect of adopting the above-mentioned further solution is that the two sets of elastically hinged check plates can cooperate with the reciprocating piston to realize the pumping and drainage work, thereby cooling the fixed-length cutting blade.

[0019] Furthermore, a connecting pipe is fixedly connected between the outer surface of the check valve near the limiting seat and the nozzle, and another check valve is connected to the water tank through a pipe, and the water tank is equipped with a water level observation window.

[0031] Please see Figures 1 to 3 A flat steel cutting machine is disclosed, comprising a cutting machine for processing flat steel. The cutting machine includes a limiting seat 2, a cutting table 3, a buffer structure 4, a mounting frame 5, a hydraulic telescopic rod 6, a cutting blade 7, and a material conveying mechanism 8, all mounted above a machine base 1. Two limiting seats 2 are fixedly installed equidistantly on the upper surface of the machine base 1. The cutting table 3 is located between the two limiting seats 2. The buffer structure 4 is fixedly installed between the machine base 1 and the cutting table 3. At least three buffer structures 4 are provided. Each buffer structure 4 consists of a buffer spring and a damping telescopic rod. The installation of the buffer structure 4 buffers the impact generated when the cutting blade 7 cuts the flat steel, thus improving the service life of the device.

[0032] In this embodiment, the mounting bracket 5 is welded to the upper surface of the two limiting seats 2, and the hydraulic telescopic rod 6 is bolted to the upper surface of the mounting bracket 5, with the output end of the hydraulic telescopic rod 6 passing through its interior and fixed to the upper surface of the fixed-length cutting blade 7. Position sensors are installed on the side of the two limiting seats 2 near the material conveying mechanism 8, cooperating with the material conveying mechanism 8 to perform fixed-length conveying. The material conveying mechanism 8 transports the flat steel until it reaches the appropriate length, at which point it stops, and the hydraulic telescopic rod 6 drives the fixed-length cutting blade 7 downwards to cut the flat steel. The mounting bracket 5, welded to the upper surface of the two limiting seats 2, secures the hydraulic telescopic rod 6, ensuring its stable and normal operation.

[0033] To achieve precise cutting, guide seats 16 are installed on opposite sides of the two limiting seats 2, and the left and right sides of the fixed-length cutting blade 7 are slidably connected to the two guide seats 16 respectively. The guide seats 16 are U-shaped. By installing the two sets of guide seats 16, the fixed-length cutting blade 7 is limited, so that the hydraulic telescopic rod 6 can linearly drive the fixed-length cutting blade 7 to move up and down, thereby improving the cutting accuracy of the fixed-length cutting blade 7.

[0034] To achieve cooling of the caliber cutting blade 7, please refer to [link / reference]. Figures 1 to 3In this embodiment, a cooling device is provided on the outside of the limiting seat 2 for linkage with the hydraulic telescopic rod 6. The cooling device includes a water tank 9, a pump body 10, a spray pipe 11, nozzles 12, and a linkage connecting arm 14. The pump body 10 includes a pump housing 1001, a piston 1003, a pump rod 1004, a check valve 1005, and a check plate 1006. A pump chamber 1002 is provided inside the pump housing 1001. The piston 1003 slides against the inside of the pump chamber 1002. The pump rod 1004 is fixedly installed on the upper surface of the piston 1003, and its top end extends to the outside of the pump housing 1001 and is connected and fixed to the outer surface of the linkage connecting arm 14. The other end of the linkage connecting arm 14 is fixed to the outer surface of the fixed-length cutting blade 7. Mounting seats 15 for fixing the spray pipe 11 are fixedly installed on the front of both limiting seats 2. Several nozzles 12 are fixedly connected to the side of the spray pipe 11 near the fixed-length cutting blade 7. By setting up several nozzles 12, the water spray range can be increased, ensuring that the fixed-length cutting blade 7 can perform cooling operations.

[0035] Specifically, there are two check valves 1005 and two check plates 1006. The two check valves 1005 are symmetrical and fixedly connected to the outer surface of opposite sides of the pump housing 1001. The two check plates 1006 are elastically hinged and installed inside the two check valves 1005. Through the two sets of elastically hinged check plates 1006, the pumping and draining operations can be achieved in conjunction with the reciprocating motion of the piston 1003, thereby cooling the fixed-length cutting blade 7. The outer surface of the check valve 1005 near the limit seat 2 is fixedly connected to the nozzle 11 by a connecting pipe 13, and the other check valve 1005 is connected to the water tank 9 through a pipe. The water tank 9 is equipped with a water level observation window. The water level observation window on the water tank 9 allows the staff to observe the water level in the water tank 9 and replenish water in a timely manner.

[0036] In this embodiment, the hydraulic telescopic rod 6 drives the fixed-length cutting blade 7 to move downward, thereby cutting the flat steel. When the fixed-length cutting blade 7 moves up and down, the piston 1003 moves up and down through the linkage connection 14 arm. The piston 1003 moves up and down continuously, changing the pressure in the pump chamber 1002. It also works with the two check plates 1006 to open and close, thus pumping water. The coolant is delivered to the spray pipe 11 through the connecting pipe 13 and finally sprayed out by the nozzle 12, thereby cooling the fixed-length cutting blade 7.

[0037] It should be noted that pump body 10 is a piston pump. The working principle of a piston pump is mainly based on the reciprocating motion of the piston within the pump cylinder. This motion changes the working volume of the pump chamber, thereby realizing the intake and discharge of liquid. The piston pump consists of a pump cylinder, piston, inlet and outlet valves, inlet and outlet pipes, connecting rod, and transmission device. When the piston reciprocates within the pump cylinder, the working volume of the pump chamber changes periodically. Intake process: When the piston moves outward, the outlet check valve closes under its own weight and pressure difference, preventing backflow of liquid in the pump chamber. Simultaneously, the inlet check valve opens under the pressure difference, allowing liquid to enter the pump chamber from the inlet pipe. As the piston continues to move outward, the volume within the pump chamber gradually increases, creating negative pressure, further promoting liquid intake. Discharge process: When the piston squeezes inward, the pressure within the pump chamber gradually increases. This causes the inlet check valve to close, preventing liquid from re-entering the pump chamber. Simultaneously, the outlet check valve opens under pressure, allowing liquid in the pump chamber to discharge through the outlet pipe. As the piston continues to move inward, the liquid in the pump chamber is completely expelled.

[0038] By linking the pump body 10 with the fixed-length cutting blade 7, the following advantages are achieved: Increased production efficiency: The automated process reduces manual operation steps, improving overall production efficiency. The linkage between the reciprocating lifting of the fixed-length cutting blade 7 and the water cooling system allows cutting and cooling to occur simultaneously, reducing waiting time. Enhanced cutting quality: Coolant sprayed through nozzle 12 quickly removes heat generated during cutting, preventing overheating and deformation of the fixed-length cutting blade 7. The coolant also reduces friction and heat accumulation on the cutting surface, improving the smoothness and quality of the cut surface. Extended equipment lifespan: The use of coolant reduces the wear rate of the fixed-length cutting blade and adjacent components, extending the equipment's lifespan. The stable operation of the hydraulic system and the water cooling system also reduces the equipment failure rate.

[0039] In this embodiment, a mounting platform for fixing the pump housing 1001 is welded to the outer surface of the limiting seat 2, and a sealing gasket is fitted onto the outer surface of the piston 1003. The installation of the sealing gasket allows the piston 1003 to better change the pressure in the pump chamber 1002 during reciprocating motion, thus improving water delivery and pumping efficiency. The depth of the pump chamber 1002 is adapted to the reciprocating movement distance of the ruler-cutting blade 7.

[0040] The working principle of the above embodiments is as follows:

[0041] In use, the flat steel is placed on the conveying mechanism 8 and transported by the conveying mechanism 8. After the flat steel is transported to the appropriate length, the conveying mechanism 8 stops. The hydraulic telescopic rod 6 drives the fixed-length cutting blade 7 to move down, thereby cutting the flat steel. When the fixed-length cutting blade 7 moves up and down, the piston 1003 moves up and down through the linkage connection 14 arm. The piston 1003 moves up and down continuously to change the pressure in the pump chamber 1002, and cooperates with the two check plates 1006 to open and close, thereby realizing the pumping operation. The coolant is delivered to the spray pipe 11 through the connecting pipe 13, and finally sprayed out by the nozzle 12 to cool the fixed-length cutting blade 7.
