Ear rib manufacturing device

The utility model provides a manufacturing device for a lug bar. The manufacturing device comprises a base, a supporting frame and a supporting frame, the first grooves correspond to the steel bars and are formed in the top surface of the base at intervals; the connecting plate is rotationally connected to the base, the side face, close to the base, of the connecting plate is provided with a protrusion corresponding to the first groove, the connecting plate is rotated in the direction close to the first groove so that the protrusion can be driven to press the portion, corresponding to the first groove, of the steel bar, and the steel bar can be bent to form the lug bar. The technical problems that traditional mechanical equipment is large in noise and difficult in use environment are solved, manufacturing of the ear ribs is facilitated, and construction efficiency is improved. 本实用新型提供了一种耳筋的制作装置，包括：供放置钢筋的基座；对应钢筋且间隔开设于该基座的顶面的第一凹槽；以及转动连接于该基座的连接板，且该连接板靠近该基座的侧面对应该第一凹槽设置有凸起，通过向靠近该第一凹槽的方向转动该连接板，以带动该凸起按压该钢筋对应该第一凹槽的部位
