Abstract

The invention discloses a whole inclined strip type mechanical compensation worktable with a dustproof structure. The worktable comprises a long base, a mounting hole used for fixing the base to a bending machine rack is formed in the bottom face of the base, a sliding groove is formed in the top of the base along the total length, a mold mounting base is mounted above the base, the bottom of thesliding groove is provided with a lower inclined strip sliding along the sliding groove, an upper inclined strip is mounted above the lower inclined strip, multiple sets of matched slopes are mountedbetween the lower inclined strip and the upper inclined strip in the length direction, one end of the lower inclined strip is provided with a motor driving the lower inclined strip to slide, the top face of the upper inclined strip is higher than the top face of the base and is attached to the bottom face of the mold mounting base, limiting pins are arranged at the positions, on the two ends of the upper inclined strip, of the bottom of the mold mounting base, the top end of the sliding groove is provided with a sinking table along the total length, dustproof cover plates are fixedly mounted at the positions, on the two sides of the upper inclined strip, in the sinking table, the dustproof cover plates and the side face of the upper inclined strip are tightly attached, two grooves are formed in the positions, on the two sides of the sinking table, of the top face of the base along the total length, and dustproof seal strips are mounted in the two grooves. The worktable has the dustproof function, and the compensation precision is improved.

Description

technical field [0001] The invention relates to the technical field of bending machine disturbance mechanical compensation, in particular to an integral slanted bar type mechanical compensation workbench with a dust-proof structure. Background technique [0002] During the bending process of the bending machine, the bottom of the slider will produce upward disturbance deformation. In order to improve the bending accuracy, the workbench under the slider is designed as a compensation mechanism that can compensate for this deformation. Most of the existing compensation mechanisms use oblique bars Compensation structure, that is, several groups of slopes with different angles are set between a pair of slopes, and the slopes of different parts of the upper slopes rise at different heights through the horizontal sliding of the bottom slopes to form a compensation curve to compensate for the disturbance deformation of the slider. However, in actual use, dust may enter the mating su...
