Description

Technical Field

[0001] The utility model relates to the technical field of steel ball forging, in particular to a forging device for wear-resistant steel balls. Background Art

[0002] Wear-resistant steel balls, also known as wear-resistant media for grinders, are consumables. Their main purpose is to grind materials to make them finer to meet usage standards. They are mainly used in mines, power plants, cement plants, steel plants, silica sand plants, coal chemical industries, and other fields. According to the production and processing technology, they are divided into forged steel balls, cast steel balls, and hot-rolled steel balls.

[0003] The steel ball forging device is a kind of equipment used for processing metal materials, usually used in the process of forging metal in the manufacturing industry. It is mainly composed of several main parts such as hydraulic system, transmission system, forging upper die and forging lower die.

[0004] The specific usage process is as follows: first place the metal blank in the forging die cavity between the forging dies; the hydraulic system provides pressure, and the transmission system drives the forging hammer to apply impact force to the metal blank through the connecting rod to deform the metal blank; through continuous forging and adjustment, the metal blank is finally forged into a workpiece of the desired shape.

[0005] Since the upper and lower forging dies are fixed and inconvenient to disassemble, only steel balls of a single size can be forged. At the same time, there is no buffer device in the placement table, which causes the impact force generated by the forging hammer when forging the metal billet to cause damage to the placement table. Utility Model Content

[0010] A damper is provided above the placement platform, a buffer spring is provided above the placement platform outside the damper, the damper and the upper end of the buffer spring are connected to the connecting plate, a plurality of blind holes are provided above the connecting plate, the forging lower die comprises a horizontal plate, a plug rod matching the blind hole is provided at the lower end of the horizontal plate, a die body is provided above the horizontal plate, and a hemispherical groove is provided above the die body;

[0011] The transmission mechanism comprises an L-shaped plate connected to the placing table, a hydraulic rod is arranged above the horizontal side of the L-shaped plate, and the lower end of the hydraulic rod passes through the L-shaped plate and is detachably connected to the forging upper die.

[0012] As an improvement, rubber rings are provided under the placement platform and the connecting plate respectively.
