Abstract

The invention provides a piano hammer head opening machine. The piano hammer head opening machine is characterized in that a transmission screw rod and a pulley track are respectively arranged on two sides of a workbench, the plane where the transmission screw rod is located is parallel to the plane of the workbench, the plane where the pulley track is located is intersected with the plane of the workbench, the transmission screw rod is connected with a first connecting rod bracket through a slider, the pulley track is connected with a second connecting rod bracket through a pulley, each of the first connecting rod bracket and the second connecting rod bracket is connected with a moving motor, each moving motor is connected with an air cylinder, each air cylinder is connected with a tool rest, each tool rest is connected with a blade through an adjusting bolt, and a fixed motor is connected with the transmission screw rod and the pulley on the pulley track. By the arrangement, primary processing of neighboring hammers in height can be realized by the aid of the pulley track, and continuity of the neighboring hammers in height can be guaranteed; by the adoption of the transmission screw rod and the adjustable blades, contour cutting of hammer bars after primary processing can be performed so as to enable cross sections of the hammer bars to be trapezoid in shape, and subsequent grinding, compregnating and trimming process can be facilitated.

Description

technical field [0001] The invention relates to the technical field of woolen processing for piano hammers, in particular to a piano hammer wool opener. Background technique [0002] The quality of the mallet for the piano hammers plays a vital role in the sound of a piano. In order to ensure the continuity of the piano scale, after the adjacent mallets are arranged in the order of the scale, the height of the mallet from the treble to the bass should form a smooth continuous slope. That is to say, during the processing of mallet woolen, it is necessary to obliquely cut the woolen raw material. Wetting, glue pressing and trimming, so as to get the required mallet. [0003] In the current market, the oblique cutting and preliminary cutting process of the mallet of the hammer are basically completed by manual operation, the repetitive labor is strong, errors are prone to occur in production, and the production efficiency is low. Contents of the invention [0004] In view ...
