Hard material shearing device and manufacturing method thereof

Abstract

The invention discloses a hard material shearing device and a manufacturing method thereof. The hard material shearing device comprises a mounting plate, a supporting part, a first rotating shaft, a second rotating shaft, a first gear, a second gear, a third gear and a handle, wherein the supporting part is fixedly mounted on the front end face of a connecting part of the mounting plate; the firstrotating shaft penetrates through a first notch part; the second rotating shaft penetrates through a second notch part; a cutting notch part is arranged at the edge of the first gear in the circumferential direction, and when the first gear rotates around the first rotating shaft, a scissor-shaped structure is formed by the upper part of the cutting notch part and the supporting part and used forshearing a hard material; and a third rotating hole is formed in the middle of the third gear. The hard material shearing device is manufactured by taking gears, which cannot be used conventionally in a workshop, as main parts, and does not need to be separately purchased, machining and manufacturing are simple, the using cost can be greatly lowered, and full utilization of waste is realized.

Description

technical field [0001] The invention relates to the field of general machinery, in particular to a hard material shearing device and a manufacturing method thereof. Background technique [0002] At present, in the production workshop or construction site, steel wire shears, hawk mouth pliers, etc. are often used to cut hard materials such as iron wires and steel wires, and various types of steel bar shears (such as hydraulic steel bar shears) are used to cut steel bars. The above-mentioned tools such as wire cutters, olecranon pliers, and steel bar cutters all need to be purchased, and generally, users cannot make them by themselves, resulting in high use and maintenance costs. On the other hand, gears, rotating shafts, and various steel pipes are very common parts in the workshop. When the gears and rotating shafts reach the scrap standard, the conventional transmission function cannot be realized, and the steel pipes are deformed and cannot be used normally, they are often...

Problems solved by technology

[0002] At present, in the production workshop or construction site, steel wire shears, hawk mouth pliers, etc. are often used to cut hard materials such as iron wires and steel wires, and various types of steel bar shears (such as hydraulic steel bar shears) are used to cut steel bars. The above-mentioned tools such as wire cutters, olecranon pliers, and steel bar cutters all need to be purchased. Generally, users cannot manufacture them by themselves, resulting in high use and maintenance costs.

On the other hand, gears, rotating shafts, and various steel pipes are very common parts in the workshop. When the gears and rotating shafts reach the scrap standard, the conventional transmission function cannot be realized, and the steel pipes are deformed and cannot be used normally, they are often discarded directly. or disposed of as scrap and sold cheaply so that it cannot be fully utilized
