Hammer

Abstract

A hammer comprises a hammer head (1) and a hammer handle (2); the hammer head (1) is of a multilayer structure, the multilayer structure is formed by alternative arranging and stacked serial connection of a metal material layer (11) and an elastic material layer (12); the metal material layer (11) is located on the outmost layer; the hammer further comprises a metal bar (13), threads are arranged at the two ends of the metal bar (13), and through the metal bar (13), the multilayer structure is in series connection together; two outmost layers of the multilayer structure are fixedly connected with the metal bar (13) through the threads; the inner layer of the multilayer structure and the metal bar (13) can axially and relatively displace within the elastic deformation range of the elastic material layer (12); according to the hammer, during use, the effective impact time of the hammer in the knocking process can be prolonged, the peak value of the knocking intensity of the hammer and an object can be properly reduced, the magnitude of knocking intensity in each time can be controlled, and damage caused by too strong stress is prevented.

Description

technical field [0001] The invention relates to the field of machining tools, in particular to a hammer. Background technique [0002] In industrial production, hammers are used as a common tool to disassemble and assemble mechanical parts. However, although existing hammers have strong versatility, they still have the following deficiencies in special occasions: [0003] 1. The effective impact time of each strike of a rigid hammer is very short. If the strike force is increased, the parts may be smashed. If the strike force is too small, the parts cannot be struck and an effective impact cannot be formed. [0004] 2. The effective impact time of each knocking object is short, and the work efficiency is low. Contents of the invention [0005] The technical purpose of the present invention is to provide a hammer that prolongs the effective impact time of the hammer during the knocking process, properly reduces the peak value of the hammer and the object's knocking force; ...

AI Technical Summary

Problems solved by technology

[0003] 1. The effective impact time of each strike of a rigid hammer is very short. If the percussion force is increased, the parts may be damaged. If the percussion force is too small, the parts cannot be knocked and an effective impact cannot be formed.

[0004] 2. The effective impact time of each knocking object is short and the work efficiency is low
