Detailed implementation

[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention, so as to have a further understanding of the concept of the present invention, the technical problems solved, the technical features constituting the technical solutions, and the technical effects brought.

[0029] As Figures 1 to 6 shown, a steel shearing device includes a base 1, a vertical left plate 2, a vertical right plate 3, a rotating base 4, a cutting platform 5, a clamping structure 6, a pressing structure 7, and a cutting structure 8;

[0030] The vertical left plate 2 is arranged at the left end of the base 1, and the vertical right plate 3 is arranged at the right end of the base 1;

[0031] The rotating base 4 is arranged on the base 1 and is located between the vertical left plate 2 and the vertical right plate 3;

[0032] The cutting platform 5 is arranged on the rotating base 4 and is used for placing steel;

[0033] The clamping structure 6 includes a left clamping plate 61, a right clamping plate 62, a second motor 63, and a reciprocating lead screw 64; the second motor 63 is arranged on the vertical left plate 2, and the output shaft is connected to the reciprocating lead screw 64; the left clamping plate 61 and the right clamping plate 62 are screwed to the reciprocating lead screw 64, and the reciprocating lead screw 64 sequentially passes through the vertical left plate 2, the left clamping plate 61, and the right clamping plate 62 and is rotatably connected to the vertical right plate 3.

[0034] The pressing structure 7 includes a left pressing structure 71 and a right pressing structure 72; the left pressing structure 71 includes a side plate 73, a second cylinder 74, a second air rod 75 and a pressing plate 76; the side plate 73 is arranged on the top of the left clamping plate 61, the second cylinder 74 is arranged on the side plate 73, the output shaft of the second cylinder 74 is connected with a second air rod 75, and the second air rod 75 passes through the side plate 73 and then is connected downward to the pressing plate 76; the right pressing structure 72 has the same structure as the left pressing structure 71 and is symmetrically arranged on the right clamping plate 62;

[0035] The cutting structure 8 is arranged on the pressing structure 7 and is used for cutting steel.

[0036] When using this device, first set the rotating base 4 on the base 1, place the steel to be sheared on the cutting platform 5, and start the second motor 63. Since the left clamping plate 61, the right clamping plate 62 and the reciprocating lead screw 64 are screwed together, the left clamping plate 61 and the right clamping plate 62 move towards the middle of the reciprocating lead screw 64. The left clamping plate 61 clamps the left end of the steel, and the right clamping plate 62 clamps the right end of the steel to achieve the stability of the steel; after the left clamping plate 61 and the right clamping plate 62 clamp the steel, start the second cylinder 74, and the second air rod 75 drives the pressing plate 76 to press downward against the upper surface of the steel. The right pressing structure 72 is the same as the left pressing structure 71 and also presses against the upper surface of the right end of the steel to achieve fixation. After cutting, the clamping structure 6 no longer clamps the steel. At this time, the left pressing structure 71 and the right pressing structure 72 jointly press the steel, ensuring the fixation of the steel and also preventing the steel from rebounding and hurting people during the cutting process; the operator starts the cutting structure 8 to shear the fixed steel. After the cutting structure 8 cuts one side, use the rotating base 4 to rotate and drive the cutting platform 5 to rotate, and the cutting structure 8 can cut the other sides of the steel. After the steel cutting is completed, loosen the pressing structure 7 to take out the steel; more preferably, the middle of the vertical left plate 2 and the vertical right plate 3 is hollow, which is more convenient to observe the cutting state of the steel at the center while reducing the material consumption. When this device cuts, the pressing structure 7 and the clamping structure 6 are fixed together. Therefore, the steel cut by the cutting structure 8 on the pressing structure 7 is a short piece with the length from the left clamping plate 61 to the cutting structure 8, ensuring the stability of the cutting.

[0037] Such as Figure 2As shown, as a preferred embodiment, the rotating base 4 includes a disc 41, a slide rail 42, a first slider 43, a second slider 44, a first motor 45, a first bevel gear 46, a second bevel gear 47, a connecting frame 48 and a connecting column 49; the disc 41 is arranged on the base 1, and the slide rail 42 is arranged in a circular shape around the edge of the disc 41; the connecting frame 48 is arranged in an inverted U shape at the center of the disc 41, the connecting column 49 is arranged on the cross bar of the connecting frame 48 and is connected upward to the cutting platform 5; the first slider 43 is arranged on the slide rail 42; the first motor 45 is arranged on the first slider 43, and the output shaft passes through the vertical frame of the connecting frame 48 and is then connected to the first bevel gear 46; the second bevel gear 47 is arranged at the center of the disc 41 and is located below the connecting frame 48, and the second bevel gear 47 meshes with the first bevel gear 46; the second slider 44 is arranged on the slide rail 42 and is symmetrical with the first slider 43, and a connecting rod 410 is arranged on the second slider 44, and the connecting rod 410 is fixedly connected to the other vertical frame of the connecting frame 48. In this embodiment, when rotation is required, first, the first motor 45 is started. The first motor 45 rotates to drive the second bevel gear 47 to rotate. Since the second bevel gear 47 meshes with the first bevel gear 46, the second bevel gear 47 rotates along the first bevel gear 46. At this time, the first slider 43 slides along the slide rail 42, driving the connecting frame 48 to rotate. Since the second slider 44 is connected to the connecting frame 48 through the connecting rod 410, the second slider 44 is also driven to slide along the slide rail 42. The second slider 44 and the first slider 43 are symmetrical to form better support. The connecting column 49 is arranged on the connecting frame 48, and the connecting column 49 is connected upward to the cutting platform 5. The rotation of the connecting column 49 can drive the rotation of the cutting platform 5 to realize the rotation of the steel.

In this embodiment, when placing the steel, first, the rectangular placement frame 51 is installed, and the steel is placed flat on the upper end of the rectangular placement frame 51.

In this embodiment, when cutting is required, the third motor 81 is started, the third motor 81 rotates to drive the lead screw 82 to rotate. Since the connecting rod 83 is screwed to the lead screw 82, at this time, the connecting rod 83 moves along the lead screw 82, driving the cutting tool 84 to move along the direction of the lead screw 82 to cut the steel below. Preferably, the cutting structure 8 can also be arranged on the right pressing structure 72. When cutting, both sides operate simultaneously, and only a 90° rotation is required after cutting to complete the cutting of the four sides of the steel.

[0042] As Figure 5 As shown, as a preferred embodiment, a limiting plate 77 is further arranged on the pressing plate 76. The limiting plate 77 is vertically arranged at the left end of the pressing plate 76, and a horizontal limiting groove 78 is arranged on the limiting plate 77. The connecting rod 83 passes through the limiting groove 78 and then is connected to the cutting tool 84. In this embodiment, the limiting plate 77 is arranged on the pressing plate 76. When the connecting rod 83 moves along the lead screw 82, it first needs to pass through the limiting groove 78, which limits the connecting rod 83 to always move along a fixed direction, improving the stability of the device.
