Abstract

The utility model relates to a forge integrated into one piece firewood sword, including blade and handle of a knife, the blade is including setting up weight and the cutting board that increases at the blade head, increases weight and cutting board integrated into one piece and is made by forging process. Furthermore, an arc-shaped cutting edge is arranged on one side of the cutting board, and a plurality of sawteeth are arranged on the other side of the cutting board. Has two functions, namely chopping firewood and sawing wood. The defects that time is delayed and efficiency is reduced due to the fact that tools are replaced in the working process are avoided. Because the weight increasing block is arranged at the head of the knife body, when firewood is cut, the impulse of the knife body is larger, the weight increasing block and the knife handle are arranged oppositely, which is equivalent to that the forces are applied at the two ends of the knife body, and the force of the knife edge is uniform. The weight increasing block and the knife plate are integrally formed and are manufactured by a forging process. The defects of cast-state looseness and the like generated in the smelting process of metal can be eliminated through forging, and the microstructure is optimized. The weight increasing block is arranged in front of the blade, so that the blade is protected.

Description

Forge integrated into one piece hacking firewood sword

Technical Field

The utility model relates to a forge integrated into one piece firewood sword belongs to and forges the work piece field.

Background

Forging is a processing method which utilizes forging machinery to apply pressure on a metal blank to cause the metal blank to generate plastic deformation so as to obtain a forged piece with certain mechanical property, certain shape and certain size. The defects of as-cast porosity and the like generated in the smelting process of metal can be eliminated through forging, the microstructure is optimized, and meanwhile, because a complete metal streamline is saved, the mechanical property of the forging is generally superior to that of a casting made of the same material. Forgings are mostly adopted for important parts with high load and severe working conditions in related machinery.

After the existing firewood knife is used for a long time, the knife tip is most easily touched with a hard object or is blocked in wood, and is often easily broken, cracked and cracked. When chopping firewood, an operator holds the handle of the knife by hand, the force is directly applied to the handle of the knife, the firewood chopping knife is lifted at a high height, then the firewood is quickly swung to the wood, and the wood is chopped by the impulse of the firewood chopping knife; because the force is directly acted on the handle of the knife, no force is exerted on the point of the knife of the firewood chopping knife, which causes the labor and the low efficiency of chopping firewood.

Due to the different tightness degree of the partial wood, the firewood chopper is difficult to cut off and only needs to use a saw. The time is delayed when the tool is searched and replaced, and the firewood chopping efficiency is reduced.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a forge integrated into one piece hacking firewood sword to solve the problem that the background art part mentioned.

In order to solve the technical problem, the utility model provides a following technical scheme: the utility model provides a forge integrated into one piece hacking firewood sword, includes blade and handle of a knife, the blade is including setting up weight and the cutting board that increases at the blade head, and weight and cutting board integrated into one piece are made by forging technology.

Furthermore, an arc-shaped cutting edge is arranged on one side of the cutting board, and a plurality of sawteeth are arranged on the other side of the cutting board. Has two functions, namely chopping firewood and sawing wood. The defects that time is delayed and efficiency is reduced due to the fact that tools are replaced in the working process are avoided.

Furthermore, the plurality of sawteeth are positioned on the same straight line, and the shortest distance from one end of the arc-shaped blade close to the weight increasing block to the straight line where the sawteeth are positioned is larger than the shortest distance from one end of the arc-shaped blade close to the knife handle to the straight line where the sawteeth are positioned. The cutting edge forms the effect that the slip sword was cut to timber, and the firewood sword is more sharp.

Furthermore, an arc-shaped cutting edge is arranged on one side of the cutting board, and a plurality of sawteeth are arranged on one side of the cutter body; the arc-shaped cutting edge is opposite to the plurality of sawteeth. The saw blade formed by a plurality of saw teeth is longer and more convenient to use.

Furthermore, the plurality of sawteeth are positioned on the same straight line, and the shortest distance from one end of the arc-shaped blade close to the weight increasing block to the straight line where the sawteeth are positioned is larger than the shortest distance from one end of the arc-shaped blade close to the knife handle to the straight line where the sawteeth are positioned.

Furthermore, a plurality of through holes are formed in the cutting board. When the firewood chopper needs to be collected, the through hole of the firewood chopper can be hung on the hook.

Furthermore, a plurality of anti-skid convex ribs are arranged on the hilt. The handle is held by hand, the slipping is not easy to happen, and the use is more convenient.

Compared with the prior art, the beneficial effects of the utility model reside in that: the knife body comprises the weight increasing block and the knife board which are arranged at the head of the knife body, so that when a firewood is cut, the momentum of the knife body is larger, the weight increasing block and the knife handle are arranged oppositely, namely, force is applied to two ends of the knife body, and the knife edge is stressed uniformly.

The weight increasing block and the knife plate are integrally formed and are manufactured by a forging process. The defects of as-cast porosity and the like generated in the smelting process of metal can be eliminated through forging, the microstructure is optimized, and meanwhile, because a complete metal streamline is saved, the mechanical property of the forging is generally superior to that of a casting made of the same material. Compared with a common firewood chopper, the high-strength wood chopper has better toughness and higher strength.

The weight-increasing block is arranged in front of the cutting edge, so that the cutting edge is protected, and the cutting edge is prevented from being broken, broken and cracked due to the fact that the cutting edge touches hard objects or is clamped in wood.

The above description is only an overview of the technical solution of the present invention, and in order to make the technical means of the present invention clearer and can be implemented according to the content of the description, the following detailed description is made with reference to the preferred embodiments of the present invention and accompanying drawings.
