Description

Technical Field

[0001] The utility model relates to the technical field of steel bar cutting, in particular to a hand-pinching prevention steel bar cutting device. Background Art

[0002] A steel bar cutting machine is a tool used to cut steel bars. It is generally divided into fully automatic steel bar cutting machines and semi-automatic steel bar cutting machines. It is one of the essential equipment for steel bar processing. Existing steel bar cutting machines do not have a hand-pinching protection function when processing and cutting steel bars. Operators often get their hands accidentally pinched due to improper operation. In addition, during the process of processing and cutting steel bars, debris is easily splashed everywhere, thus accidentally injuring workers. Utility Model Content

[0003] In order to overcome the problem that the existing steel bar cutting device has no anti-pinch function, which leads to accidental pinching of hands during the steel bar cutting process and the problem that debris splashes during the steel bar cutting process and easily injures workers by mistake, the embodiment of the utility model provides an anti-pinch steel bar cutting device. The technical solution is as follows:

[0004] A finger-pinching-proof steel bar cutting device comprises a base, wherein the top right side of the base is fixedly connected to a body, the right end of the body is provided with an electric hydraulic cylinder, the left end of the body is provided with a right cutter, the output end of the electric hydraulic cylinder movably passes through the body and is fixedly connected to the right cutter, the top left side of the base is fixedly connected to a baffle, the right side surface of the baffle is fixedly connected to a left cutter capable of cutting with the right cutter, the top of the base is located outside the baffle and a hinge is provided, the base is hinged with a protective cover through the hinge, the front and rear ends of the protective cover are provided with slots, and the protective cover A conductive sheet is fixedly connected to the inner wall, a placement groove is provided on the top of the baffle, a conductive column is provided in the placement groove, a relay is installed on the top of the base, and the relay is electrically connected to the electric hydraulic cylinder through a wire. Only when the protective cover is buckled can the device start to cut the steel bars, which not only effectively avoids the problem of workers forgetting to buckle the protective cover or being unwilling to buckle the protective cover when cutting the steel bars, thereby easily causing the problem of pinching the hands during the steel bar cutting process, but also the notches at both ends of the protective cover are used to place the steel bars, which also effectively avoids the problem of debris splashing and accidentally injuring the workers during the steel bar cutting.

[0005] Furthermore, a spring is fixedly connected to the bottom end of the inner cavity of the placement slot, the top of the spring is fixedly connected to the bottom of the conductive column, and the conductive column is movably connected in the placement slot. After the protective cover is buckled, the elastic force of the spring enables the conductive column to always press the conductive sheet upward, thereby ensuring that the conductive column and the conductive sheet are fully in contact, and further enabling the relay to maintain a stable energized state.

[0006] Furthermore, a limiting groove is opened at the left end of the inner cavity of the placement groove, and a limiting block is movably connected in the limiting groove. The limiting block is fixedly connected to the side surface of the conductive column. The limiting groove and the limiting block ensure that the conductive column will not fall out of the placement groove.

[0007] Furthermore, the left cutter and the right cutter are on the same horizontal line, thereby ensuring that the left cutter and the right cutter are accurately overlapped, thereby improving the effect of the left cutter and the right cutter on cutting the steel bars.

[0008] Furthermore, the protective cover is a transparent cover, which is convenient for observing the condition of the steel bars in real time when cutting the steel bars, and convenient for observing whether the steel bars are cut.

[0009] Furthermore, a handle is fixedly connected to the left end of the protective cover.

[0010] Furthermore, a roller group is arranged at the lower end of the base.

[0011] The beneficial effect of the technical solution provided by the embodiment of the utility model is as follows: the utility model enables the protective cover to overlap the baffle and the machine body through a hinge, so that the protective cover protects the left cutter and the right cutter while also making the conductive column contact the conductive sheet, thereby starting the relay to control the electric hydraulic cylinder to push the right cutter to cut the steel bar, and when cutting the steel bar, the electric hydraulic cylinder can only work when the protective cover blocks the left cutter and the right cutter, and the protective cover not only prevents accidental hand pinching due to improper operation during steel bar processing and cutting, but also prevents debris from splashing and accidentally injuring workers during the process of steel bar processing and cutting.
