Embodiment 135

[0022] In this embodiment, the production process of the hammer head of the 135 hammer crusher is taken as an example, and the specific production process steps are as follows:

[0023] 1. Mold, core box, sand core, leaky molding machine preparation process:

[0024] ① The mold, runner, and riser system are made of aluminum alloy, processed by CNC lathe, the surface accuracy is CT1-CT3, and the roughness is ≤1.6μm; the shrinkage rate in the length direction is 1%, and the shrinkage rate in the width direction is 0.8% ;

[0025] ② The material of the core box is aluminum alloy, the surface precision is CT1-CT3, and the roughness is ≤1.6 μm; the cavity size is adjusted according to the shrinkage of the model;

[0026] ③ The sand core is a long core head with radial and axial positioning pins at one end to prevent displacement during pouring.

[0027] ④The leaky mold molding machine is an integrated equipment. The leaky mold molding machine is composed of a cubic frame, a pall...

Abstract

The invention relates to a process for casting a wear-resistant hammer head, in particular to a process for casting the wear-resistant hammer head by compounding two kinds of metal liquid. A method for synchronously smelting and pouring the two kinds of metal liquid, and molding by using a stripping plate molding machine is adopted. The process comprises the following steps of: manufacturing a mold, a core box, a sand core and the stripping plate molding machine, molding, smelting, pouring, opening the box for cleaning, and performing heat treatment. The hammer head cast by the process has the characteristics of high toughness, strength and wear resistance, the conditions of cracking and falling-off of a hammer handle and the hammer head can be avoided, and wear resistance is high; the stripping plate molding machine is convenient and easy to use, a casting mold is standard, production efficiency is high, and production cost is low; meanwhile, multiple purposes can be achieved, and hammer heads of multiple specifications can be provided for users.

Description

[0001] technical field [0002] The invention relates to a casting process of a wear-resistant hammer head, in particular to a double-furnace synchronous melting of two materials of a hammer handle and a hammer head, and a double-metal liquid-liquid composite casting wear-resistant hammer for horizontal casting and vertical casting is realized according to the shape of a leaky mold molding machine. head craft. Background technique [0003] Hammer crusher is a special crushing equipment for metallurgical mines and cement industry. In the production of crushing various materials, various materials are crushed by hammer heads. Its main component, the hammer head, is a vulnerable spare part that is consumed in large quantities. Traditional hammerheads are cast with high manganese steel or ultra-high manganese material, forged after cutting the top of track steel, and bimetallic liquid-solid composite casting. However, in practical application of these traditional products, due...
