Problems solved by technology

[0005] Besides, during the working process of the crusher, when the two working surfaces of the hammer head are worn out, it is necessary to stop the machine and remove all the hammer heads that can no longer be used.
The work of disassembling a large number of hammerheads is not only labor-intensive, but also greatly reduces production efficiency.
In addition, the unworn hammer handle metal material is wasted, and the worn hammer head is replaced at the same time. If it is an inlaid casting of two materials, due to the large difference in the mass fraction of the chemical composition, it will bring inconvenience to recycling and remelting

Abstract

The invention discloses a spherical hammer head of a combined crusher and a manufacturing method thereof. The hammer head comprises a spherical hammer end (1) and a hammer handle (2); the spherical hammer end (1) and the hammer handle (2) are combined into the integral hammer head through a connecting rod (3); the spherical hammer end is cast by adopting an alloy high-chromium cast iron losing die; and the hammer handle is made of No. 45 round steel by a metal processing and cutting method. The spherical hammer head of the crusher has the advantages of abrasion resistance, good toughness, quick replacement of the spherical hammer end and long-term use of the hammer handle, improves the production efficiency, saves the metal material, and is particularly suitable for manufacturing hammer heads of reversible small and medium hammer crushers.

Description

technical field [0001] The invention relates to a hammer head of a crusher, in particular to a spherical hammer head of a combined crusher and a manufacturing method thereof. Background technique [0002] Hammer crushers mainly rely on impact to crush materials. Therefore, the hammer head is the main force-bearing part of the crusher, and it is also the most easily worn part. Every year, the whole country consumes tens of thousands of tons of metal materials due to hammer damage. How to improve the service life of the hammer head and reduce the consumption of wear-resistant materials has always been the goal of scientific and technological workers. [0003] Among the many hammer crushers, it is difficult to choose the material of the hammer head of the medium and small hammer crushers, which account for the largest number in absolute terms. This type of hammer head bears a moderate impact force and crushes brittle materials with medium or lower hardness. It is made of hig...
