The punching table 1 includes a table frame 11 and a cover 12 assembled behind the table frame 11.

[0037] A material unloading rack 111 is provided at the position of the workbench frame 11 corresponding to the installation position of the machine head 2. The material unloading rack 111 includes a mounting plate 1111 fixedly mounted to the workbench frame 11 by bolts, a plurality of material unloading holes 1112 provided on the mounting plate 1111, and an inclined material unloading plate 1113 fixed below the mounting plate 1111 and corresponding to the material unloading holes 1112; an equipment cabin 112 is also provided at the rear of the workbench frame 11. Specifically, the equipment cabin 112 is used to install a circulating hydraulic system 7, an air-cooled oil tank 8 and a circulating cooling system 9.

[0038] like Figure 5-6As shown, the machine head 2 includes a machine head frame 21, an angle steel punching die 22 fixedly mounted inside the machine head frame 21, a first puncher 23 with a hydraulic cylinder fixed on one side above the machine head frame 21, a first chamfering device 24 with a hydraulic cylinder cooperating with the first puncher 23, a second puncher 25 with a hydraulic cylinder fixed on the other side above the machine head frame 21, a second chamfering device 26 with a hydraulic cylinder cooperating with the second puncher 25, a vertical press 27 with a hydraulic cylinder fixedly mounted on the feeding end of the machine head frame 21, a vertical cutter 28 with a hydraulic cylinder fixedly mounted on the discharging end of the machine head frame 21, and a solenoid valve group 29 connecting the first puncher 23, the first chamfering device 24, the second puncher 25, the second chamfering device 26, the vertical press 27, the vertical cutter 28, the feeding mechanism 3 and the discharging mechanism 4;

[0039] The solenoid valve group 29 includes a horizontal bar 291 with a channel opened inside, a hydraulic oil input head 292 installed at one end of the horizontal bar 291, an input pressure-maintaining valve 293 fixedly connected to the horizontal bar 291 in cooperation with the hydraulic oil input head 292, a hydraulic oil output head 294 installed at the other end of the horizontal bar 291, an output pressure-maintaining valve 295 fixedly connected to the horizontal bar 291 in cooperation with the hydraulic oil output head 294, and a plurality of solenoid valves 296 fixedly connected to the horizontal bar 291.

[0040] The hydraulic oil input head 292 is provided with an oil inlet pipe 2921, which is connected to the accumulator 73;

[0041] The hydraulic oil output head 294 is provided with an oil return pipe 2941, which is connected to the air cooling oil tank 8 through the oil return pipe 2941, so that the used high-temperature hydraulic oil can flow back to the inside of the air cooling oil tank 8 for cooling.

[0042] See also Figure 5 The feeding mechanism 3 includes a feeding base 31 with a built-in screw motor, a feeding workbench 32 assembled on the feeding base 31, and a feeding fixture 33 with a hydraulic cylinder installed on the feeding workbench 32.

[0043] See also Figure 5 The discharging mechanism 4 includes a discharging base 41 with a built-in screw motor, a discharging workbench 42 assembled on the discharging base 41, and a discharging fixture 43 with a hydraulic cylinder installed on the discharging workbench 42.

[0044] like Figure 7As shown, the circulating hydraulic system 7 includes an oil pump 71 whose output end is connected to the air-cooling oil tank 8, a motor 72 that drives the oil pump 71 to operate the booster, and an energy storage device 73 connected to the output end of the oil pump 71; a pumping hose 711 is provided at the input end of the oil pump 71, and the oil pump 71 is connected to the air-cooling oil tank 8 through the pumping hose 711; a pumping hose 712 is provided at the output end of the oil pump 71, and the oil pump 71 is connected to the energy storage device 73 through the pumping hose 712.

[0045] The lower end of the accumulator 73 is provided with a three-way connector 731, which is specifically connected to the pump-out hose 712 and the oil inlet pipe 2921 provided on the hydraulic oil input connector 292.

[0046] It should be further explained that the accumulator is a device for storing energy and can release the energy when needed. In the hydraulic system of the present invention, the accumulator is installed on the high-pressure side of the oil pump 71 of the hydraulic system, and its main function is to absorb pressure fluctuations or impact forces, thereby stabilizing the operation of the system. These fluctuations or impact forces are generated by various factors in the system, including but not limited to:

[0047] Rapid start or stop: When the oil pump 71 in the hydraulic system is started or stopped quickly, impact force will be generated. The accumulator can absorb this impact force and reduce the pressure fluctuation in the system.

[0048] Valve operation: The operation of the solenoid valve may also cause sudden changes in pressure, especially when the valve is opened or closed quickly, which will produce pressure fluctuations. The accumulator can alleviate this pressure fluctuation.

[0049] Load changes: When the load in the hydraulic system changes, such as a sudden increase or decrease in load, it will cause a change in system pressure. The accumulator can help balance this pressure change and keep the system stable.

[0050] Working characteristics of oil pump 71: The working characteristics of oil pump 71 can also cause pressure fluctuations in the system, especially in high-pressure systems. The accumulator can absorb part of the energy during the operation of the pump to stabilize the output flow and pressure of the system. Therefore, the role of the accumulator in the hydraulic system is very important. It can protect the components of the system, extend their service life, and improve the stability and reliability of the system.

[0051] like Figure 8As shown, the air-cooled oil tank 8 includes a storage box 81, a plurality of inlet fans 82 mounted on the storage box 81, and a plurality of oil and gas filtering devices 83 mounted between two inlet fans 82 and capable of cooperating with the inlet fans to perform circulating air supply. Specifically, the coordinated use of a plurality of inlet fans and the oil and gas filtering devices can realize circulating air supply and effectively cool the hydraulic oil in the storage box 1. The design of the oil and gas filtering device can effectively filter the oil and gas, protect the hydraulic equipment from the influence of impurities, and improve the reliability and stability of the equipment.

[0052] like Fig. 9 As shown, the circulating cooling system 9 includes an exhaust fan 91, and a compression refrigeration mechanism 92 that cooperates with the exhaust fan 91 to air-cool the interior of the punching workbench 1. The compression refrigeration mechanism 92 includes a compressor 921, a liquid storage tank 922, an evaporator 923 and a condenser 924. The evaporator 923 is mounted at the air outlet end of the exhaust fan 91 and is respectively connected to the compressor 921 and the liquid storage tank 922, while the condenser 924 is mounted at one end close to the air-cooled oil tank 8 and is respectively connected to the compressor 921 and the liquid storage tank 922, forming a compression refrigeration circuit;

[0053] The circulating cooling system 9 also includes an exhaust fan 925 mounted on the condenser 924 . Specifically, the exhaust fan 925 is used to accelerate the extraction and exhaust of the inside of the punching workbench 1 , so that a cooling cycle is formed inside the punching workbench 1 .

[0054] See also Fig.10 During circulating cooling, the compression refrigeration mechanism 92 operates normally. Specifically, the exhaust fan 91 draws air from the outside of the equipment and sends it into the equipment compartment 112. The input air absorbs heat and cools through the evaporator 923, and then enters the interior of the equipment compartment 112. Then, the air exchanges heat with the oil pump 71, the motor 72 and the air-cooled oil tank 8 inside the equipment compartment 112, and is finally extracted and discharged through the exhaust fan 925. At the same time, the temperature of the extracted air is still lower than the temperature of the air outside the equipment. Therefore, when the air passes through the condenser 924, it can exchange heat with the condenser 924, so that the condenser 924 can be cooled quickly, which can improve the refrigeration efficiency of the entire compression refrigeration mechanism 92.

[0055] During the circulating cooling process, the air-cooled oil tank 8 can also cooperate with the compression refrigeration mechanism 92 to further cool the hydraulic oil inside the storage box 81. The air inlet fan draws cold air from the top of the equipment compartment 112 into the storage box 81, and contacts and exchanges heat with the high-temperature hydraulic oil sent into the storage box 81 after being circulated by the circulating hydraulic system 7, and then is discharged through the oil and gas filtering device. The circulating air supply can be realized to accelerate the cooling of the hydraulic oil, thereby ensuring the smooth operation of the first puncher 23, the first chamferer 24, the second puncher 25, the second chamferer 26, the vertical press 27, the vertical cutter 28, the feed clamp 33 and the discharge clamp 43.

[0056] The above embodiments of the present invention are not intended to limit the protection scope of the present invention, and the implementation modes of the present invention are not limited thereto. All other modifications, replacements or changes made to the above structures of the present invention based on the above contents of the present invention, in accordance with common technical knowledge and customary means in the art, without departing from the above basic technical ideas of the present invention, should fall within the protection scope of the present invention.
