Description

Fixed die ejection mechanism of steel ball rapid forging machine

Technical Field

The utility model relates to a steel ball quick forging machine fixed mould ejection mechanism belongs to steel ball production facility technical field.

Background

The ball mill is the key equipment for crushing the materials after the materials are crushed. It is widely used in the production industries of cement, silicate products, novel building materials, refractory materials, chemical fertilizers, black and non-ferrous metal ore dressing, glass ceramics and the like, and carries out dry or wet grinding on various ores and other grindable materials.

The steel ball of the ball mill is a medium for grinding materials in ball mill equipment, and has the main function of impacting and crushing the materials and also has a certain grinding function, so that the wear-resistant steel ball is the most vulnerable part in the ball mill, and the demand on the wear-resistant steel ball is huge in many foreign countries with sufficient mining industry.

The production process types of the wear-resistant steel balls mainly comprise forging (rolling) and casting, wherein the cast steel balls are gradually eliminated due to unstable internal quality, poor wear resistance and high consumption; the production of forged (rolled) grinding balls currently has several ways:

1. air hammer half die forging: the steel bar is cut off in a cold state, heated in a heating furnace, and then forged and formed in a die of an air hammer in a plurality of actions. The method has the advantages of multiple operation links, high labor intensity and low production efficiency;

2. press upset (hot upset for example): cutting a steel bar in a cold state, heating the steel bar in a heating furnace (or heating the steel bar firstly and then cutting the steel bar), sending the steel bar into a die of a press machine by a mechanical device, and performing extrusion forming for 1 time or 2 to 3 times of stamping actions. The mode reduces the labor intensity, has higher production efficiency, but has slightly poor spherical shape;

3. roll forging by a roll forging machine: cutting a steel bar in a cold state, heating the steel bar by a heating furnace (or heating the steel bar firstly and then cutting the steel bar), performing by a pre-forging machine, and forming by a roll forging machine. Compared with air hammer semi-die forging, the method has the advantages that the yield and the quality are improved, but the method is influenced by equipment and human factors, the quality is unstable, and the production cost is high;

4. rolling by a rotary cutting roll forging machine: the round bar of steel is heated in a heating furnace, rolled in a rotary cutting roll forging machine, and rolled into balls through three main processes of cutting, forming and rolling, and generally, one steel ball is produced every time a roller rotates one circle. The method has high production efficiency, ensures the surface quality of the produced grinding balls, and has the potential of further improving the yield and the heat treatment effect.

At present, a rotary cutting roll forging machine is generally adopted in the market to produce wear-resistant steel balls, when the machine works, a steel round bar is heated and then is fed between two rotary cutting rollers, the two rotary cutting rollers respectively comprise a cutting section, a forming section and a rolling section, the round bar is rolled into balls through three processes of cutting, forming and rolling, the production efficiency is higher than that of other modes, but the production requirement is still not increased day by day, and therefore the machine is necessary to provide a steel ball fast forging machine with higher production efficiency.
