Manual hammer head presser

Abstract

The invention relates to a manual hammer head presser. A vertical pressing mechanism comprises a radial pressing frame, a first radial lead screw and a first lead screw nut, wherein the radial pressing frame is fixed to a center shaft, the first lead screw nut is installed on the radial pressing frame, and the first radial lead screw penetrates through the first lead screw nut to drive a hammer head to make vertical translation towards a bottom die. Each horizontal pressing mechanism comprises a longitudinal screw, a left pressing block and a right pressing block, wherein the left pressing block and the right pressing block clamp the left side and right side of the center shaft respectively and make horizontal translation along the center shaft to drive a left pressing die and a right pressing die to conduct translation, the longitudinal screw is arranged horizontally, the middle of the longitudinal screw penetrates through the center shaft, the left section and right section of the longitudinal screw are matched with an internal thread hole of the left pressing block and an internal thread hole of the right pressing block respectively, and the directions of threads of the internal thread hole of the left pressing block and the internal thread hole of the right pressing block are opposite. The manual hammer head presser has the advantages of being simple in structure, convenient to operate, capable of saving energy, low in manufacturing cost, small in occupied area and high in production efficiency and belongs to the technical field of piano part manufacturing equipment.

Description

technical field [0001] The invention relates to equipment for making piano parts, in particular to a manual hammer press. Background technique [0002] Piano hammers are an important part of the piano used to strike the strings, which include hammer cores and felts. The heads of the hammer cores are pointed, and the felt is wrapped around the heads. Hammer cores have a rectangular tail. [0003] Hammers are generally made by the following methods: cutting the left and right sides of a slender wooden workpiece (cube) near the head into a specific shape to obtain a long strip-shaped hammer wood core without cutting the tail; The felt press is fixed at the head of the whole wood core; the wood core and the felt are cut along the cross-section to obtain a complete set of 88 hammers for a piano. [0004] A whole piece of piano hammer has the following characteristics: the cross-sectional shape is symmetrical on the left and right sides; along the length direction of the workpi...

AI Technical Summary

Problems solved by technology

[0006] Existing hydraulic presses for forming piano hammers have the following disadvantages: 1. Due to the long pressure holding time during the pressing process, if hydraulic pressure is used to maintain pressure, the hydraulic machine must be kept open, which consumes electric energy and increases production costs

2. The lower mold mechanism and the side mold mechanisms on both sides all use oil cylinders. One piece of equipment is equipped with at least four oil cylinders. The equipment is bulky and occupies a large area

3. The cost of equipment is high

4. Regular maintenance and cleaning of hydraulic pipelines must ensure that there is no oil leakage
