[0015] The technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative efforts belong to the scope of protection of the present invention.

[0016] It should be noted that in the following solutions, the orientation concepts of "left", "right", "up", "down", "front", "back", "inside", and "outside" are all relative directions, and will not be listed one by one here.

[0017] A fully automatic leveling and cutting production line for steel, refer to Figures 1-5 , which includes a steel feeding roller assembly 1, a leveling roller assembly 2, a first platform 3, a cutting assembly 4, and a second platform 5 that are connected in sequence. The steel is detachably arranged on the steel feeding roller assembly 1. The steel feeding roller assembly 1 conveys the steel, first levels it through the leveling roller assembly 2, and finally moves it to the second platform 5. The cutting assembly 4 cuts the steel, and the cut steel sheets are stacked and left on the second platform 5.

[0018] The steel feeding roller assembly 1 adopts an existing steel feeding roller device, which is very common and will not be described in detail here.

[0019] The leveling roller assembly 2 includes a leveling platform 21. A leveling roller 22 and a motor 23 for driving the leveling roller 22 to work are arranged on the leveling platform 21. A lower leveling frame 221 is arranged at one end of the leveling roller 22 close to the steel feeding roller assembly 1, and two guiding wheels 25 distributed up and down are arranged close to the first platform 3. The leveling roller 22 includes a lower leveling frame 221 arranged on the leveling platform 21. A plurality of lower leveling rollers 222 are arranged between the lower leveling frames 221. Transmission gears 223 are arranged at the ends of the lower leveling rollers 222. A plurality of transmission gears 223 are sequentially meshed with each other. The output end of the motor 23 is connected to one of the lower leveling rollers 222. Two screw rods 224 are respectively rotatably arranged on both sides of the lower leveling frame 221. The upper leveling frame 225 is in threaded rotation connection with the four screw rods 224. A plurality of upper leveling rollers 226 are rotatably arranged between the upper leveling frames 225. The four screw rods 224 are respectively in transmission connection, and the transmission connection method is realized through gears and transmission rods. Since this is a very existing technology, it will not be described in detail here. Rotating one of the screw rods 224 can drive the upper leveling frame 225 to move up and down in parallel.

[0020] The cutting assembly 4 includes a cutting table 41. A cutting seat 42 is arranged on the cutting table 41. A cutting tool 45 is arranged to slide up and down on the lower side of the cutting seat 42, and the lower side of the cutting tool 45 is an inclined plane. Two second hydraulic cylinders 44 for driving the sliding of the cutting tool are arranged on the upper side of the cutting seat 42. Two first hydraulic cylinders 43 are arranged on the front side of the cutting seat 42, and a pressing plate 46 is arranged at the output end of the lower end of the first hydraulic cylinder 43.

[0021] The first output end of the two-way oil supply pump 6 is communicated with the rodless cavity of the first hydraulic cylinder 43 through the first oil pipe 61 and with the rodless cavity of the second hydraulic cylinder 44 through the second oil pipe 62. A pressure valve 63 is arranged on the second oil pipe 62. A first parallel oil circuit 64 is arranged on the second oil pipe 62, and both ends of the first parallel oil circuit 64 are communicated with both ends of the pressure valve 63. The second output end of the two-way oil supply pump 6 is communicated with the rod cavity of the first hydraulic cylinder 43 through the third oil pipe 66, and the second output end of the two-way oil supply pump 6 is communicated with the rod cavity of the second hydraulic cylinder 44 through the fourth oil pipe 67.

[0022] When a cutting operation needs to be performed, the first output end of the two-way oil supply pump 6 supplies oil and the second output end sucks oil. Due to the existence of the pressure valve 63, the two-way oil supply pump 6 first drives the pressing plate 46 to descend to firmly press the steel. When the pressing force is greater than the set value of the pressure valve 63, at this time, the hydraulic oil supplies oil to the second hydraulic cylinder 44 through the pressure valve 63 to complete the cutting. When the cutting is completed, the first output end of the two-way oil supply pump 6 sucks oil and the second output end supplies oil. At this time, the pressing plate 46 and the cutting tool 45 rise simultaneously.

[0023] The pressure valve 63 includes a body 7 with a hollow interior and open ends. A first annular through port 71 and a second annular through port 72 are formed in the body 7. A sealing ball 73 is arranged in contact with one side of the first annular through port 71 close to the second annular through port 72. A return spring 74 in a compressed state and connected to both ends thereof is arranged between the sealing ball 73 and the second annular through port 72.

[0024] The above are only the preferred embodiments of the present invention. It should be understood that the present invention is not limited to the forms disclosed herein, should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be changed within the scope of the concept described herein through the above description or the technology or knowledge in related fields. And the changes and modifications made by those skilled in the art without departing from the spirit and scope of the present invention should all be within the protection scope of the appended claims of the present invention.
