specific Embodiment approach 1

[0012] Embodiment 1: A hammer head for a double-fluid bimetal compound hammer crusher in this embodiment is composed of a head 1 , a hammer handle 2 and a dovetail partition 6 between the head and the hammer handle.

[0013] The hammer head of the double-liquid bimetallic compound hammer crusher in this embodiment uses two pouring systems, and the two metal liquids are poured at the same time. The timing is not accurate and the molten metal is mixed with each other, and a dovetail-shaped partition is inserted at the part where the head and the hammer handle are combined in the cavity. The temperature of the molten metal during pouring can not only partially melt the dovetail-shaped separator under the action of the molten metal, but also have a complete bonding interface, and can also play a corresponding isolation role to obtain metallurgical bonding, which will not fall off during use and prolong the use. Longer life, lower overall production cost.

specific Embodiment approach 2

[0014] Embodiment 2: This embodiment differs from Embodiment 1 in that the material of the head 1 is high chromium cast iron, low chromium anti-wear white cast iron, medium chromium anti-wear white cast iron or high manganese steel. Others are the same as in the first embodiment.

specific Embodiment approach 3

[0015] Embodiment 3: This embodiment differs from Embodiment 1 or Embodiment 2 in that the hammer handle 2 is made of cast steel or low-alloy steel. Others are the same as in the first or second embodiment.

Abstract

The invention relates to a hammer head for a two-fluid duplex metal composite hammer crusher and a manufacturing method thereof. By the hammer crusher, the technical problems of low combination strength of a hammer handle and a hammer head and high cost in the conventional duplex metal composite hammer head are solved. The duplex metal composite hammer head consists of a head part, a hammer handle and a swallowtail-shaped partition board positioned between the head part and the hammer handle. The manufacturing method comprises the following steps of: manufacturing a cavity of the hammer head; performing acid washing and drying on the swallowtail-shaped partition board, and fixing the swallowtail-shaped partition board in the cavity; and pouring molten metal of the head part and molten metal of the hammer handle simultaneously, and cooling to obtain the hammer head for the two-fluid duplex metal composite hammer crusher. According to the hammer head, the head part and the hammer handle are combined in a metallurgy mode, so that the hammer is high in abrasive resistance, long in service life and reliable in crack resistance, can crush a large amount of stuff and can be used for the hammer crusher.

Description

technical field [0001] The invention relates to a hammer head for a hammer crusher and a preparation method thereof. Background technique [0002] Hammer crusher is an important crushing equipment, which is widely used in mining, electric power, coal and other industries. The hammer head is an important part of the hammer crusher. During use, the hammer handle is constantly subjected to alternating bending stress and impact force, which requires sufficient strength and toughness, while the hammer head is in direct contact with the crushed material. High hardness and wear resistance are required. Due to the different working conditions and performance requirements of the hammer handle and the hammer head, the bimetal composite hammer head can well meet the requirements of high wear resistance and high safety and reliability. The existing preparation method of the bimetal composite hammer head is: first cast or process the hammer handle, preset it in the mold cavity as an in...
