Abstract

The invention discloses a pressing machine of a piano sound board frame. The pressing machine includes a rectangular top frame, four supporting legs arranged at the four corners of the rectangular frame correspondingly, and a worktable connected with the four supporting legs and located on the lower portion of the rectangular top frame. The four edges of the rectangular top frame are provided witha plurality of first cylinders correspondingly, and piston rods of the first cylinders pass vertically downward through the rectangular top frame and are used for compressing a resonant board and a sound board frame placed on the worktable. According to the pressing machine of the piano sound board frame, the sound board frame and the resonant board of a piano are automatically compressed, the working efficiency is improved, and the labor intensity of workers is lowered.

Description

technical field [0001] The invention relates to the technical field of piano manufacturing, in particular to various piano soundboard frame presses. Background technique [0002] In the piano manufacturing process, the soundboard frame needs to be compressed after it is bonded to the resonant plate. At present, each can only be compressed separately by the existing press. Since it is not a special press, its time Inconvenient operation and low work efficiency. [0003] It can be seen that the prior art still needs to be improved and enhanced. Contents of the invention [0004] In view of the disadvantages of the above-mentioned prior art, the object of the present invention is to provide a piano soundboard frame press, aiming at solving the technical problems of inconvenient pressing of the soundboard frame and low work efficiency in the prior art. [0005] In order to achieve the above object, the present invention has taken the following technical solutions: [0006] ...
