Description

Technical Field

[0001] The utility model belongs to the technical field of metal plate cutting tools, and in particular relates to a metal plate cutting tool. Background Art

[0002] Metal plates generally have extremely strong ductility. Steel plates, as the metal plates with the largest share in industrial use, can be made into various structural parts and mechanical parts after cutting, combining, bending or stamping, such as containers, oil storage tanks, packaging boxes, train carriages, car shells, etc. With the continuous development of the modern mechanical processing industry, the requirements for improving production efficiency and controlling production costs in cutting steel plates are also increasing. Therefore, various semi-automatic cutting machines and fully automatic CNC cutting machines have been put into operation. However, these machines are not only expensive and only suitable for large-scale manufacturing enterprises, but also generate a lot of cutting dust and noise when used. Additional sound insulation and dust collection treatment are required in the factory area to achieve environmental protection, which further increases the cost of use conditions.

[0003] In the prior art, a patent document with the announcement number CN 108127156 B discloses a cutting device, including a base plate, a bracket, a fixed plate, a first connecting rod, a first pin rod, a pedal, etc.; three brackets are fixedly connected above the base plate, a fixed plate is fixedly connected to the upper end of the bracket, a first connecting rod is provided on the left side of the base plate, the first connecting rod is rotatably connected to the base plate through a first pin rod, and a pedal is fixedly connected to the left end of the first connecting rod. The above scheme drives the cutting device to complete the cutting work through the pedal, which solves the problem of cutting dust and noise, but the transmission structure of the equipment is too complicated, not only the cutting shear force is prone to be insufficient, but also the cutting accuracy will be lower with the use for a longer time, and the maintenance is difficult.

[0023] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection, a mechanical connection, a direct connection, or a connection through an intermediate medium, or the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0024] Example:

[0025] like Figure 1 , Figure 2 and Figure 3 As shown: a metal plate cutting tool includes two base structures 1. The two base structures 1 are arranged in parallel with each other, or they can be non-parallel. It is sufficient for all the base structures 1 to be arranged relative to each other. This makes it convenient for the operator to walk between the two base structures 1 and drag the metal plate to be cut. More base structures 1 can be arranged to make the metal plate to be cut more stably placed, but it is generally not necessary. Connecting plates can also be arranged between the base structures 1 to connect them together. The connecting plates are arranged close to the ground so as not to interfere with the movement of the operator.

[0026] A cutting tool mounting frame 2 is provided at one end of the base frame structure 1, a cutting tool device 3 is installed on the cutting tool mounting frame 2, and elastic pads 4 are also installed on the base frame structure 1. The elastic pads 4 are used to place metal plate materials and make the metal plate materials flush with the angle bisector between the tool edges in the cutting tool device 3.

[0027] The above-mentioned cutting tool device 3 includes a fixed cutting tool 31 and a movable cutting tool 32. The fixed cutting tool 31 can be detachably mounted on the cutting tool mounting frame 2. A rotating shaft structure 33 is arranged at one end of the fixed cutting tool 31, and one end of the movable cutting tool 32 is rotatably connected to the fixed cutting tool 31 through the rotating shaft structure 33. The cutting edge of the fixed cutting tool 31 and the cutting edge of the movable cutting tool 32 are arranged opposite to each other, and the cutting edge of the fixed cutting tool 31 is arranged to be tilted downward, so that the metal plate material is flush with the angular bisector of the cutting edge angle between the fixed cutting tool 31 and the movable cutting tool 32. In this way, only the movable cutting tool 32 is driven downward, and the cutting edge of the fixed cutting tool 31 and the cutting edge of the movable cutting tool 32 will evenly apply force to shear the metal plate material from the upper and lower sides, so that no dust and noise will be generated during the cutting process, and the cutting edge will be more uniform and smooth, and the torque required during the cutting process can also be reduced, or thicker metal plate materials can be cut.

[0028] A handle structure 34 is also provided at the other end of the movable cutting tool 32. The handle structure 34 is installed on the end of the movable cutting tool 32 by plugging or threading. The handle structure 34 is a hollow tube, and the length of the handle structure 34 is 0.5 to 2 meters. Since the shear force is provided by manual operation, the manufacturing cost is low, so it can only be used for small-scale or sample cutting. In addition, the handle structure 34 is more lightweight and it is convenient for the operator to replace the handle structure 34 of different lengths as needed to provide sufficient shear torque.

[0029] The rotating shaft structure 33 is a bolt structure, and the fixed cutting tool 31 is detachably mounted on the cutting tool mounting frame 2 through the bolt structure, so that the cutting tool device 3 can be easily disassembled, repaired or polished in various parts or as a whole.

[0030] The elastic pad 4 includes a movable pad 41 and an elastic component group 42. A limited groove structure 43 is also provided on the base frame structure 1. The movable pad 41 is installed in the limited groove structure 43. One end of the elastic component group 42 is connected to the movable pad 41, and the other end of the elastic component group 42 is connected to the base frame structure 1 or the limited groove structure 43. The elastic component group 42 is arranged in various directions and can be directly compressed at the bottom of the movable pad 41 or as shown in the figure. Figure 3As shown, the reverse stretching setting is convenient for disassembly, and the elastic component group 42 mainly functions to lift the movable pad 41 in the limiting groove structure 43. In the natural state, the upper surface of the movable pad 41 is horizontal, and the metal plate material placed on the movable pad 41 is also horizontal. The metal plate material is sheared to different positions between the cutting edge of the fixed cutting tool 31 and the cutting edge of the movable cutting tool 32, and the metal plate material is maintained at different heights by the elastic component group 42, thereby ensuring that the metal plate material is flush with the bisector of the cutting edge angle between the fixed cutting tool 31 and the movable cutting tool 32.

[0031] The cross-section of the movable pad 41 is "T"-shaped, and magnetic structures 5 are evenly arranged on both sides of the movable pad 41. The magnetic structure 5 is used to attract the metal plate material to be cut onto the movable pad 41. The metal plate material is generally a steel plate, an iron plate or an iron-containing material. In this way, the positioning of the metal plate material to be cut is more stably during the cutting process of the cutting tool device 3, and the cutting position can be more accurate. At this time, the metal plate material is not completely fixed and can still be dragged and fed, so that the cutting tool device 3 completes continuous cutting of the metal plate material.

[0032] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention shall be defined by the appended claims.
