[0032] The steel cutting device for construction of the present invention has two usage modes:

[0033] Usage 1: Place the cutter in Figure 5 The cutter is set downwards in the manner of being set downwards, and the cutter is limited by the two first blocks. At this time, steel parts such as steel bars or steel sheets are placed on the workbench, the part to be cut is aligned with the cutter position, and the hydraulic cylinder is started to press the cutter down to cut the steel part;

[0034] Usage 2: Press the first limit block and the second limit block on one side of the cutter, rotate the cutter upward, release the first limit block and the second limit block, and the cutter is now restricted by the two second phase blocks. At this time, pull the second workbench to separate the second workbench from the first workbench, then place steel parts such as steel bars or steel sheets on the workbench, start the hydraulic cylinder pressing shaft, and press the steel parts down along the edge of the first workbench to form a bend.

[0035] In summary, the steel cutting device for construction of the present invention has not only the cutting function but also the bending function, and has more functions than the existing cutting equipment.

[0036] In order to improve the cutting effect, a strip hole 25 may be provided on the second workbench corresponding to the position of the cutter, so that the position of the steel piece to be cut is suspended, which facilitates the cutter to move down to a position below the bottom end of the steel piece and completely cut the steel piece.

[0037] It should be noted that the above-mentioned limiting structure is only one implementation of this embodiment. As long as the function of the cutter being able to rotate so that the blade of the cutter changes to a downward state can be achieved, no specific limitation is made here. Of course, in this application, the cutter can preferably be rotated so that the blade of the cutter faces upward to ensure that the back of the knife can contact the steel part in usage mode 2.

[0038] As a preferred implementation, see Figure 1-Figure 4, a first support 13 is arranged under the first workbench. Generally, the first support can be a support column or a support leg. The number of support legs can be set according to the size of the first workbench, which is well known to those skilled in the art and will not be repeated here; a second support 14 is arranged under the second workbench, and the second workbench is slidably connected to the second support. Similarly, the second support can generally be a support column or a support leg. The number of second supports can be set according to the size of the second workbench, which is well known to those skilled in the art and will not be repeated here; a semicircular protrusion 15 is arranged at one end of the first workbench close to the second workbench, and a semicircular groove matching the semicircular protrusion is arranged at one end of the second workbench close to the first workbench; first connecting plates 16 are rotatably connected on both sides of the first workbench, and a first connecting rod 17 is arranged between the two first connecting plates, one end of the first connecting rod is connected to one of the first connecting plates, and the other end of the first connecting rod is connected to the other first connecting plate, and the first connecting rod is located at The first connecting plate is connected to an end of the first workbench; a second connecting plate 18 is connected to the first connecting plate and is located below the first connecting plate, a second connecting rod 19 is arranged between the two second connecting plates, one end of the second connecting rod is connected to one of the second connecting plates, and the other end of the second connecting rod is connected to the other second connecting plate, and the second connecting rod is located at the end of the second connecting plate not connected to the first connecting plate; the shaft extends out of the first connecting block and the second connecting block, and a third connecting plate 20 is fixedly connected to both ends of the shaft, and a third connecting rod 21 is fixed to the third connecting plate, and the third connecting rod is located at the end of the third connecting plate not connected to the shaft; the third connecting rod is located on the side of the shaft facing away from the cutter; in this embodiment, the third connecting plate is preferably located on the inner side of the first connecting plate and the second connecting plate; the end of the third connecting rod not connected to the third connecting plate is located on the outer side of the first connecting plate, and the distance between the first connecting rod and the second connecting rod is greater than the thickness of the second workbench.

[0039] The above structure can be used in two ways:

[0040] Usage 1: Place the cutter in Figure 5The cutting knife is restricted by two first blocks, at which time the first connecting rod is located above the second workbench, and the second connecting rod is located below the second workbench. The upper first connecting rod allows steel parts such as steel bars or steel sheets to pass through from below the first connecting rod and then releases the first connecting rod, so that the steel parts are restricted below the first connecting rod. In this way, when cutting the steel parts, the first connecting rod forms a restriction on the steel parts to prevent them from being vibrated and offset during cutting and detaching from the second workbench. When making structures such as the first connecting plate and the second connecting plate, the distance between the first connecting plate and the second connecting plate can generally be set according to the thickness of the steel parts frequently cut. Of course, an elastic member, such as a spring sheet, can be set above the first connecting plate to enable the first connecting rod to press the rod member. Figure 8 As shown, the first connecting plate is divided into two parts, the part connected with the first workbench is integrated with the second connecting plate, and the other part is made of a spring sheet, and finally the two parts are connected;

[0041] Usage 2: Press the first limit block and the second limit block on one side of the cutter, rotate the cutter upward, release the first limit block and the second limit block, at this time the cutter is restricted by the two second phase blocks, at this time, pull the second workbench to separate the second workbench from the first workbench, then put the first connecting rod on the platform to make steel parts such as steel bars or steel sheets pass through the bottom of the second connecting rod and then release the first connecting rod, start the hydraulic cylinder to press the third connecting rod downward so that the third connecting rod presses down the first connecting plate and then drives the second connecting plate and the second connecting rod to move downward and to the left, press the steel parts along the edge of the first workbench and move to the left to form a bend, so that the bending angle can be larger, such as Figure 2 As shown, in particular, the second connecting plate is in an arc shape with an opening disposed toward the end where the first connecting plate is connected to the first workbench, so that the bending angle can be increased.

[0042] As an implementation method, see Figure 3 , third supports 22 are provided on both sides of the second workbench. The third supports can be support columns or support legs. For overall firmness, the third supports can be connected to the first support or the second support through a support plate. A fourth connecting plate 23 is provided between the third supports on both sides of the second workbench, and the hydraulic cylinder is fixed on the fourth connecting plate; a connector 24 is fixed on the top surface of the first connecting block and the second connecting block, and the connector is generally a rectangular parallelepiped; there is one hydraulic cylinder, and the power output end of the hydraulic cylinder is connected to the first connecting body. In actual production, a horizontal plate can also be fixed on the third support on the right, and an electric telescopic device can be installed on the horizontal plate to connect the second workbench for easy operation. As a variation, see Figure 4Alternatively, two hydraulic cylinders may be provided without a connector, and the power output end of one of the hydraulic cylinders may be directly connected to the first connecting block, and the power output end of the other hydraulic cylinder may be directly connected to the second connecting block. This is a transformation method well known to those skilled in the art and will not be described in detail here.
