After cutting the steel plate, in order to improve the compactness of the subsequent overlap, the upper and lower edges of the steel plate cut need to be polished to make the cut smooth. The existing steel plate cut grinding method generally uses manual handheld angle grinders. The grinding operation is time-consuming and labor-intensive, the grinding intensity is high, and the grinder cannot be stabilized during the manual grinding process, resulting in uneven grinding of the edges of the steel plate cut, affecting the quality of the steel plate overlap. Summary of the invention

[0007] It is further preferred that a lifting frame that moves up and down is installed on the walking frame through a slide, and the upper mold and the upper end of the tilt adjustment cylinder connected to the upper mold are connected to the lifting frame. The height of the lifting frame is adjusted, and the distance between the upper mold and the lower mold is adjusted, which is suitable for steel plates with different plate thicknesses.

[0008] Further preferably, a vertical first lifting and adjusting screw is mounted on the traveling frame via a bearing, and the lifting frame is connected to the first lifting and adjusting screw via threads.

[0009] Further preferably, the steel plate clamping mechanism is composed of a lifting and adjusting cylinder vertically installed on a frame, a pressing plate installed at the lower end of a piston rod of the lifting and adjusting cylinder, and a supporting beam installed on the frame and located below the pressing plate.

[0010] Further preferably, a lifting adjustment mechanism is connected between the upper end of the frame and the lifting adjustment cylinder to adjust the height of the lifting adjustment cylinder and adjust the lifting operation range of the pressure plate.

[0011] Further preferably, the lifting adjustment mechanism is composed of a second lifting adjustment screw vertically installed on the upper end of the frame through a bearing and a lifting beam connected to the second lifting screw through a thread, and the upper end of the lifting adjustment cylinder is fixedly installed on the lifting beam.

[0015] The beneficial effects of the present invention are:

[0016] 1. The steel plate cutting grinder replaces the traditional manual grinding method with mechanical grinding, which saves time and effort and reduces the grinding intensity.

[0017] 2. Due to the traveling frame that moves left and right in the middle of the frame, the upper and lower grinding tools are installed on the traveling frame and the extended surfaces of the grinding sheets are crossed and opposite, and a steel plate clamping mechanism is set on the corresponding grinding sheet side of the frame. The steel plate is clamped and fixed by the pressing plate and the support beam, so that the upper and lower grinding tools can grind the upper and lower edges of the steel plate cut straight from one side of the steel plate to the other side, thereby improving the grinding stability, making the grinding surface of the steel plate smooth, and improving the overlap quality of the steel plate.

[0018] 3.
