[0003] Shearing machines are divided into mechanical shearing machines and hydraulic shearing machines. Hydraulic shearing machines generally include clamping columns, workbenches, hydraulic lifting mechanisms, cutters, connecting rod mechanisms and electrical control systems. When in use, the plate to be cut is placed on the workbench, and then the hydraulic lifting mechanism is controlled to drive the clamping columns and cutters to move up and down. The clamping columns clamp and fix the plate, and the cutters cut the plate. For longer plates, the plates will be cut multiple times. During the cutting process, some iron filings will be generated. If the iron filings generated by the last cutting remain on the upper surface of the plate, some of the debris will fly around when cutting again, which can easily cause harm to the operator and cause collapse at the blade, which will not only affect the sharpness of the blade, but also affect the cutting effect of the plate; some debris falls into the internal dead corners such as the corners and grooves of the machine tool, which brings inconvenience to the operator when cleaning, and the accumulation of debris seriously affects the shearing quality and efficiency of the plate.

Compared with the traditional iron filing collection and cleaning method, the upper magnetic strips and the lower magnetic strips are convenient to maintain, easy to operate, low in manufacturing cost, simple in structure and easy to install, which greatly improves production efficiency.

[0037] like Figure 3-Figure 8As shown, in this embodiment, the upper knife 11 passes through the body and a plurality of screws 13 are horizontally arranged and fixed on the upper knife holder 12. The screw 13 body has an inner cavity screw hole 20, and the inner cavity screw hole 20 is adapted to be nested with a countersunk inner bolt 21 for fixing and locking. The upper knife 11 is adapted to be pressed against the upper knife holder 12. The upper knife holder 12 and the upper knife 11 are fixed by the screw 12 passing through themselves and threaded. An inner cavity screw hole 20 is further arranged on the screw 12 body, and a countersunk inner bolt 21 is adapted in the inner cavity screw hole 20. The countersunk inner bolt 21 further locks the screw 13. The countersunk inner bolt 21 is located on one side of the upper magnetic strip 16 to prevent the bolt head from being blocked, so that the upper magnetic strip 16 can magnetically absorb iron filings. The upper knife 11 is pressed against and installed on the upper knife holder 12. The lower right angle formed by the upper tool holder 12 and the upper extension edge 15 improves the stability of the upper knife 11 and prevents the upper knife 11 from shifting; the lower knife 14 passes through the main body and is horizontally provided with several inner screws 17 adapted to be fixed on the end face of the machine table 9, and the inner screw 17 is located on one side of the lower magnetic strip 19.

[0038] like Figure 1-Figure 2As shown, in this embodiment, the guard plate 7 is arranged on one side close to the machine 9, and the guard plate 7 is fixed on the machine body 1. A protective net 8 is arranged directly below the guard plate 7. The body of the protective net 8 is fixed by a plurality of fixing strips 22 arranged on the guard plate 7. The bottom end surface of the body of the protective net 8 is directly spaced from the machine 9 by 3-10 cm. The protective net 8 blocks the splashing of iron filings generated during cutting, prevents the user from being injured, and improves the safety of steel plate cutting; and the body of the clamping mechanism 10 is arranged on the rear side of the guard plate 7, and the distance between the clamping mechanism 10 and the guard plate 7 is at least 20 cm; the rear of the body of the clamping mechanism 10 An upper tool holder 12 is arranged on the side, and the distance between the upper tool holder 12 and the clamping mechanism 10 is at least 20 cm; the clamping mechanism 10 and the upper tool holder 12 are driven to rise and fall respectively by a plurality of hydraulic telescopic rods 6; a main switch box 2 and a control panel 5 are arranged on both sides of the body 1, and the main switch box 2 and the control panel 5 are electrically connected to the power supply respectively; the shearing machine greatly reduces the free scattering of iron filings, reduces the user's cleaning of debris in the dead corners of the machine tool, and prevents the blade from breaking, which affects the cutting quality and efficiency of the shearing machine.

[0039] The working principle of the use of the technical solution provided by the present invention is as follows: the user first puts the plate 3, which is a steel plate, and uses an automatic conveying mechanism to convey the steel plate to the machine table 9. The dynamic conveying mechanism clamps and pushes one side of the plate, and indirectly promotes the displacement of the steel plate through a set program. The automatic conveying mechanism is an existing product on the market and will not be described in detail here. Turn on the main switch box button on the side wall of the machine body 1, and set the cutting specifications and dimensions of the plate 3, the feeding interval time of the automatic conveying mechanism, the pressing and rising interval time of the clamping mechanism 10, etc. on the control panel 5. The operation of the shearing machine is controlled by a PLC control system in the control panel 5. The PLC control system is installed in the control panel 5. The existing product on the market, which will not be described in detail here, is vertically installed on one side of the machine body 1 close to the machine table 9. A guard plate 7 is mounted on the body 1, and a protective net 8 is fixedly installed directly below the guard plate 7. The protective net 8 is at least 7 cm away from the machine table 9 to facilitate the passage of the plate 3. A clamping mechanism 10 is arranged on the rear side of the protective net 8. The clamping mechanism 10 is used to clamp and fix the cut plate 3. An upper knife holder 12 is arranged on the rear side of the clamping mechanism 10. An upper extension edge 15 is arranged on a side wall of the bottom end surface of the upper knife holder 12 body close to the clamping mechanism 10. The upper extension edge 15 is integrally formed with the upper knife holder 12 and is a lower right-angle structure. The upper knife 11 is installed against the lower right angle. The upper knife 11 is mutually adapted through a screw 13 and a countersunk inner screw 21 to lock and fix the upper knife 11 on the upper knife holder 12. A plurality of upper magnetic strips 1 are adapted to be installed on the lower surface of the upper extension edge 15 horizontally and away from the upper knife 11. 6. The upper magnetic strip 16 is used to magnetically absorb the debris on the steel plate. When the upper knife holder 12 drives the upper knife 11 to move down for cutting and rise for separation, the upper magnetic strip 16 approaches the plate 3 when moving down to magnetically absorb the iron scraps remaining on the upper surface of the plate 3. The distance that the upper knife 11 moves down for cutting is half of the total height of the upper knife 11 body, so as to prevent the upper magnetic strip 16 from magnetically absorbing the entire plate 3. A lower extension edge 18 is horizontally arranged on the rear end surface of the machine table 9 body. The lower extension edge 18 is integrally formed with the machine table 9 and is an upper right-angle structure. The lower knife 14 is installed in contact with the upper right angle. The lower knife 14 is fixed to the rear end surface of the machine table 9 by an inner screw. A plurality of lower magnetic strips 19 are adapted to be installed on the lower surface of the lower extension edge 18 horizontally and away from the lower knife 14. The lower magnetic strip 19 is used to magnetically absorb the debris produced by cutting the plate 3 to prevent the debris. The upper extension edge 15 is integrally formed with the upper knife holder 12 and the upper knife 11 is installed at the lower right angle, and the lower extension edge 18 is integrally formed with the machine table 9 and the lower knife 14 is installed at the upper right angle, which enhances the stability of the upper knife 11 and the lower knife 14 and prevents the upper knife 11 and the lower knife 14 from being offset. The upper knife 11 and the lower knife 14 are mutually dislocated and vertically arranged, and the upper knife 11 and the lower knife 14 have a gap, which is convenient for cutting the plate. When the upper knife 11 moves downward for shearing, the upper magnetic strip 16 and the lower magnetic strip 19 are used for magnetic absorption and collection of the broken iron chips generated by the shearing of the plate 3, reducing the collapse of the blade and the random scattering of the broken iron chips. The upper magnetic strip 16 and the lower magnetic strip 19 are magnetically attracted to the upper extension edge 15 and the lower extension edge 18 respectively, which is convenient for maintenance and cleaning of the broken iron chips.After the sheet 3 is cut, the upper knife holder 12 drives the upper knife 11 to rise and leave the sheet 3, the clamping mechanism 10 rises and releases the sheet 3, and the sheet 3 automatically enters the blanking table 4, the blanking table 4 collects the sheet 3, and the automatic conveying mechanism conveys the sheet 3, and the above steps are repeated in sequence to complete the intermittent continuous cutting of the sheet 3. ;

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
