Working table provided with T-shaped grooves

The utility model relates to the technical field of bending machine equipment, in particular to a working table provided with T-shaped grooves. The working table provided with the T-shaped grooves comprises a working table, front supporting devices and bolts, wherein the T-shaped grooves are formed in two side surfaces of the working table; the large end parts of the bolts are clamped and buckled in the T-shaped grooves; the bolts can horizontally slide in the direction of the T-shaped grooves; and the front supporting devices are fixed on the side surfaces of the working table through the bolts. Compared with the prior art, the large end parts of the bolts of the working table provided with the T-shaped grooves are clamped and buckled in the T-shaped grooves, and the bolts can horizontally slide in the T-shaped grooves, so that the front supporting devices fixed by the bolts can further horizontally slide in the direction of the T-shaped grooves and can freely move in the length range of the whole working ta
