Description

Technical Field

[0001] The utility model relates to the technical field of steel bar bending machines, in particular to a steel bar pressing and bending integrated device. Background Art

[0002] M steel strips are usually required in the process of anchor support in mines. Since the design and construction shape of mine tunnels is mainly a straight wall semicircular arch or a three-center arch cross-section, in order to ensure that the exposed length of the anchor meets the requirements, the M steel strips need to be bent according to the tunnel contour during the process of anchor support. Due to the relatively simple underground construction environment, the existing method of making M-shaped steel bars is usually manual bending, which has low efficiency, high safety risks, high labor intensity and unstable quality, and does not meet the use requirements.

[0005] Furthermore, the hydraulic jack is connected to the oil tank of the self-propelled machine through an oil pipe, and the oil inlet and outlet are controlled by a control valve group.

[0006] Furthermore, the top of the hydraulic jack is hinged to the moving block via a rotating shaft; the main body of the hydraulic jack is fixed to the middle of the connecting steel plate via a buckle.

[0007] Compared with the prior art, the utility model has the following advantages: the steel bar pressing die bending integrated device designed by the utility model can be fixed on the tail of the self-moving machine working underground, and the M-shaped pressing die plate can be adjusted to squeeze downward by controlling the lifting of the hydraulic jack, so as to perform the steel bar M-shaped pressing operation and produce the M-shaped steel strip. After the pressing film is formed, the hydraulic jack can be controlled to bend the formed M-shaped steel strip by sliding the hydraulic jack to the other side. The steel bar pressing die bending integrated device has good quality, high efficiency, and labor saving. It can bend the M-shaped steel bar according to the demand while producing the M-shaped steel bar quickly, thereby ensuring the production efficiency of the underground M-shaped pressing die plate.
