Description

Technical Field

[0001] The utility model relates to the technical field of steel bar production, in particular to a bisecting shearing device of a steel bar production system. Background Art

[0002] There are multiple process stages in the production of steel bars, including melting, continuous casting, hot rolling, cooling, shearing, marking, surface treatment and other process stages.

[0003] At present, in the conventional steel bar production process, since the steel bars are in a state of continuous transportation before being sheared, flying shears are usually used for shearing steel bars, which use impact force to rhythmically break the continuous steel bars into fixed preset lengths for easy transportation and subsequent processing. However, although the current flying shears can quickly break the continuous steel bars, the cross-section of the directly broken steel bars is very irregular, resulting in the need to cut the cross-section before subsequent use to make the end face of the steel bar neat, which not only wastes materials and increases the cost of material use, but also requires manual processing of irregular cross-sections, increasing the subsequent labor cost.

[0004] Based on the above background, the inventor has designed a bisecting shearing device for a steel bar production system, which can solve the current problem of irregular cross-section of steel bars after shearing, and thus proposed the present application. Utility Model Content

[0044] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0045] like Figures 1 to 4 As shown, this embodiment provides a bisection shearing device for a steel bar production system, comprising:

[0046] Base 1, base 1 is located directly below the steel bar conveying channel;

[0047] A vertical guide rod 4, wherein the vertical guide rod 4 is vertically arranged on the base 1;

[0048] A punching seat 2, which is located directly above the base 1 and the steel bar conveying channel, and is slidably connected to the vertical guide rod 4;

[0049] A linear drive mechanism 3, the linear drive mechanism 3 is located above the punching seat 2, and an output end thereof is fixedly connected to the punching seat 2;

[0050] It also includes two cutter mounting seats 5 which are arranged opposite to each other and have steel bar matching grooves 51. The two cutter mounting seats 5 are slidably connected with the base 1 and the punching seat 2 along the steel bar conveying direction.

[0051] A reset structure is provided between the base 1 and the cutter mounting seat 5, and between the punching seat 2 and the cutter mounting seat 5;

[0052] A lower cutter 6 and an upper cutter 7 are arranged on opposite sides of the two cutter mounting seats 5 .

[0053] like Figures 1 to 3 As shown, the design concept of this embodiment is to set a base 1, a punching seat 2, a linear drive mechanism 3, two cutter mounting seats 5, and a lower cutter 6 and an upper cutter 7 respectively arranged in the two cutter mounting seats 5, so that when the linear drive mechanism 3 drives the punching seat 2 to move downward, the lower cutter 6 and the upper cutter 7 can cut the steel bar. In this process, since the cutter mounting seat 5 is slidably connected with the base 1 and the punching seat 2, the lower cutter 6 and the upper cutter 7, as well as the two cutter mounting seats 5 will move with the movement of the steel bar until the steel bar is cut. The present application is also provided with a reset structure for driving the cutter mounting seat 5 to reset. After the linear drive mechanism 3 drives the punching seat 2 to reset, the reset structure will drive the lower cutter 6 and the upper cutter 7, as well as the two cutter mounting seats 5 to reset, waiting for the next cutting action to cut the next section of the steel bar.

[0054] Therefore, the present application utilizes the lower cutting knife 6 and the upper cutting knife 7 to cut the steel bars. Compared with the punching action of the original flying shear, the cut cross-section of the steel bars is smooth and does not need to be cut again during subsequent use, which can avoid subsequent material waste and save material and labor costs.

[0055] Specifically, Figure 1 and Figure 2 As shown, the top of the base 1 and the bottom of the punching seat 2 are both provided with a knife seat mounting groove 11;

[0056] A slide bar 12 with an axis parallel to the steel bar conveying channel is arranged in the knife seat installation groove 11, and the cutter installation seat 5 is slidably connected with the slide bar 12;

[0057] The reset structure is arranged in the knife seat mounting groove 11, and the reset structure is located downstream of the cutter mounting seat 5 along the steel bar conveying direction. By arranging the slide bar 12, not only can the sliding of the cutter mounting seat 5 be guided, but also the cutter mounting seat 5 located above can be suspended at the bottom of the punching seat 2.

[0058] Specifically, in this embodiment, Figure 2 As shown, the reset structure is a reset spring 13 sleeved on the slide bar 12. In some embodiments, technicians can also use a drive mechanism such as a cylinder telescopic rod, which will not be described here.

[0059] Specifically, in this embodiment, Figure 1 and Figure 2 As shown, the cutter mounting seat 5 is provided with a cutter mounting groove 52 which is arranged perpendicular to the steel bar conveying channel;

[0060] The lower cutter 6 and the upper cutter 7 are both detachably inserted in the cutter installation slot 52. The lower cutter 6 and the upper cutter 7 are detachably connected to the cutter installation slot 52, so that the lower cutter 6 and the upper cutter 7 are conveniently replaced.

[0061] Specifically, in this embodiment, Figure 1 and Figure 2 As shown, the lower cutter 6 and the upper cutter 7 are both pressed and fixed in the cutter installation groove 52 by screws or screws. By screws or screws, the lower cutter 6 and the upper cutter 7 can be pressed against the side wall of the cutter installation groove 52 to play a fixing effect.

[0062] Specifically, in this embodiment, Figure 1 As shown, the lower cutter 6 and the upper cutter 7 have the same structure;

[0063] The lower cutter 6 comprises a lower cutter body 61 and a lower cutter edge 62, and the lower cutter edge 62 protrudes upward and is arranged on the top surface of the cutter mounting seat 5 located above;

[0064] The upper cutter 7 comprises an upper cutter body 71 and an upper cutter edge 72, wherein the upper cutter edge 72 protrudes downward from the bottom surface of the cutter mounting seat 5 below;

[0065] The upper blade 72 and the lower blade 62 have the same height;

[0066] It also includes a positioning protrusion 8 arranged between the two cutter mounting seats 5, and the thickness of the positioning protrusion 8 is the same as the height of the lower cutting edge 62 or the upper cutting edge 72.

[0067] In this embodiment, the protrusion 8 is set in place to prevent the upper blade 72 and the lower blade 62 from contacting structures other than the steel bar when cutting the steel bar, causing damage to the upper cutter 7 and the lower cutter 6. In this embodiment, the size of the lower cutter 6 and the upper cutter 7 is also the same, which can reduce the manufacturing cost.

[0068] Specifically, in this embodiment, Figure 4 As shown, the lower blade 62 and the upper blade 72 are both beveled blades, and the angles between the blade slopes of the lower blade 62 and the upper blade 72 and the horizontal plane are the same. In this embodiment, the angles between the blade slopes of the lower blade 62 and the upper blade 72 and the horizontal plane are both 60°.

[0069] Specifically, in this embodiment, Figure 1 and Figure 3 As shown, the longitudinal section of the steel bar matching groove 51 is arc-shaped, and the size of the arc-shaped steel bar matching groove 51 matches the size of the outer peripheral wall of the steel bar;

[0070] The sum of the height of the upper blade 72 or the lower blade 62 and the depth of the steel bar matching groove 51 of the two cutter mounting seats 5 is equal to the diameter of the steel bar. The arc-shaped steel bar matching groove 51 can prevent the steel bar from shaking left and right during the cutting process. In this embodiment, the cut steel bar is a round steel bar.

[0071] Specifically, Figure 1 As shown, the linear drive mechanism 3 is a hydraulic telescopic cylinder invertedly arranged on the top of the vertical guide rod 4. The use of the hydraulic telescopic cylinder can provide sufficient power for cutting the steel bars. Technicians can also design other drive types of linear drive mechanisms 3 as needed, which will not be given here.

[0072] Specifically, the lower cutter 6 and the upper cutter 7 are both made of hard alloy, so that the lower cutter 6 and the upper cutter 7 do not need to be replaced frequently.

[0073] Specifically, in this embodiment, a cable (not shown in the figure) fixed on the punching seat 2 is also provided. The cable is located upstream of the cutter mounting seat 5 along the steel bar moving channel and is arranged close to the cutter mounting seat 5. The steel bar is located between the cable and the punching seat 2, so that during the resetting process of the punching seat 2, the auxiliary steel bar returns to the original steel bar conveying channel, avoiding the problem of resetting relying solely on the elasticity of the steel bar itself.

[0074] It is understood that the above embodiments are merely exemplary embodiments used to illustrate the principles of the present invention, but the present invention is not limited thereto. For those skilled in the art, various modifications and improvements can be made without departing from the spirit and essence of the present invention, and these modifications and improvements are also considered to be within the scope of protection of the present invention.
