Technical Field

[0001] The utility model relates to the technical field of steel plate bending and forming machines, in particular to an improved oil cylinder rod positioning component used for steel plate bending and forming. Background Art

[0002] In the process of conveying steel plates, the existing steel plate bending and forming machine can bend the steel plates once every conveying distance, and the steel plates can be formed into a C shape by bending them multiple times. Figure 1 When feeding the plate, a vacant slot 101 is formed on a section of the conveying surface of the steel plate to avoid the bending knife. In order to prevent the vacant slot 101 from failing to support the transition of the steel plate during the feeding process, a cylinder space 1011 is formed below the corresponding vacant slot 101 in the body of the steel plate bending and forming machine. The cylinder barrel of the oil cylinder is arranged in the cylinder space 1011, and the oil cylinder rod 1 of the oil cylinder can penetrate into the vacant slot 101 and a supporting seat 2 is arranged on the top of the oil cylinder rod 1. When feeding the plate, the oil cylinder rod 1 rises, and the transition steel plate is supported by the supporting seat 2, so that the steel plate can smoothly transition from the vacant slot 101.

[0003] At present, in order to stabilize the lifting of the oil cylinder rod of the oil cylinder, a mounting groove 103 is recessed at the bottom of the vacant groove 101 corresponding to the through-hole 102 of the oil cylinder rod 1, and a positioning cover 3 for the oil cylinder rod 1 to pass through is installed in the mounting groove 103, so that the positioning cover 3 improves the stability of the lifting of the oil cylinder rod 1. The existing positioning cover 3 and the mounting groove 103 are mainly fastened by opening a plurality of bolt holes at intervals on the outer edge of the positioning cover 3 and inserting bolts in each bolt hole, but the force of the oil cylinder rod 1 will be transmitted to the positioning cover 3. With long-term use, the positioning cover 3 is easily loosened under the action of the force, thereby affecting the stabilizing effect of the positioning cover 3 on the lifting of the oil cylinder rod 1.
