Description

Technical Field

[0001] The utility model relates to the technical field of steel bar production, in particular to a single-knife pressure-cutting 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. The impact force is used 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, which results 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 increases the subsequent labor costs. Therefore, the use of flying shears in the steel bar production system is only suitable for steel bars with low requirements for the cut section.

[0004] To solve the problem of incomplete cuts, one of the solutions in the industry is to use pressure cutting to cut the steel bars. Currently, pressure cutting is usually performed from both sides of the steel bars to avoid changing the moving position of the steel bars during the cutting process and causing the machine to get stuck. However, pressure cutting from both sides of the steel bars usually uses two drive mechanisms and two cutting knives, which have high manufacturing costs and subsequent operation and maintenance costs.

[0005] Based on the above background, the inventor has designed a single-blade pressure-cutting shearing device for a steel bar production system to solve the problem that the current steel bar pressure-cutting method requires two driving mechanisms and cutting knives, and has a complex structure and high cost. Therefore, the present application is proposed. Utility Model Content

[0024] The top of the cutting knife protrudes outward from the cutting knife installation groove, and the height of the cutting knife protruding from the cutting knife installation groove is less than the depth of the knife groove;

[0025] The knife sleeve seat is also provided with an anti-sway groove for preventing the steel bar from shaking;

[0026] The cutter mounting seat is also provided with a steel bar matching groove which is arranged parallel to the steel bar conveying channel, and the bottom of the steel bar matching groove is semicircular.

[0033] Beneficial effects of the utility model:

[0034] 1. The design concept of the present application is to provide a cutter mounting seat and a knife sleeve seat, and to provide a cutting knife on the cutter mounting seat, and to provide a knife groove on the knife sleeve seat. Once the knife sleeve seat is driven to move downward by the linear drive mechanism, the steel bar can be pushed to move downward, so that the steel bar is cut by the cutting knife on the cutter mounting seat. Since the present application cannot cut the steel bar instantly, during the cutting process, the steel bar that has not been broken will drive the cutter mounting seat and the knife sleeve seat to move forward until the cutting edge of the cutting knife and a part of the knife body are inserted into the knife groove to completely cut the steel bar. The present application is also provided with a reset structure for driving the cutter mounting seat to reset. After the linear drive mechanism drives the knife sleeve seat to move upward and reset, the reset structure will drive the cutter mounting seat, the cutting knife, and the knife sleeve seat to reset, waiting for the next cutting action to cut the next section of the steel bar.

[0035] Therefore, compared with conventional cutting methods, the present application can cut the steel bars using a single linear drive mechanism and a single cutting knife, saving the number of linear drive mechanisms and cutting knives while ensuring the integrity of the cut section of the steel bars, which can effectively solve the problems of the prior art.

[0036] 2. The present application also provides a lifting structure, and the lifting structure is located upstream of the cutting knife along the direction of steel bar conveying. Therefore, after the steel bar is cut, the linear drive mechanism drives the knife sleeve to move upward and reset. The lifting structure will assist the steel bar to quickly return to the original conveying channel, solve the problem of displacement of the steel bar during the cutting action, and make preliminary preparations for the next steel bar cutting action.
