The Working Principle Of Electric Reciprocating Saw

The electric reciprocating saw is an electric tool for sawing with a reciprocating saw blade. It is a kind of electric saw, which is generally composed of a casing, a motor, a transmission mechanism, a knife lifting mechanism, a saw blade, and a switch. Electric reciprocating saw A power tool for sawing with a reciprocating saw blade. The electric reciprocating saw is used for sawing metal plates, pipes, profiles, or cutting bevels on steel pipes. It can also cut cables or other non-metal materials.

The realization of the reciprocating motion of the saw blade: A common crank connecting rod mechanism is adopted for transmission, which converts the rotation of the crank into the reciprocating motion of the reciprocating rod in a straight line. The bearing and the big gear form a crank, one end of the connecting rod is connected to the reciprocating rod through a universal joint, and the other end of the connecting rod is connected to the crank; The motor drives the big gear to rotate, and the reciprocating rod is driven back and forth through the connecting rod. To balance, it is equipped with a balance weight, which is driven by an eccentric wheel to reciprocate simultaneously with the reciprocating rod.

The realization of the swing movement of the electric reciprocating saw blade: realized by a rocker mechanism. The knife lifting bracket is equipped with a reset spring, one end of which is connected to the movable block, the reciprocating rod passes through the movable block, and the other end is interlocked with the knife lifting hook. , The knife lifting hook is also reciprocating back and forth at the same time. The knife lifting bracket is hooked by the theme to move together, thereby driving the movable block and the reciprocating rod to swing up and down. Different end faces are processed on the knife lifting shaft. Different swing amplitudes can be obtained for the end face of the cutter shaft.

electric reciprocating saw blade clamping mechanism: It clamps the electric reciprocating saw blade through a pressing plate and a fixing screw and fixes it on the head of the reciprocating rod. There is a positioning pin on the end face of the reciprocating rod to hook the saw blade to prevent the saw blade from falling out. There are two types of saw blade chuck devices: common type and fast type. The general quick clamping mechanism has been patented by some well-known brand companies. If it is to be used, patent issues must be considered.

The impact of stroke length on machine cutting: Stroke length refers to the maximum distance the electric reciprocating saw blade moves back and forth during the cutting process. The stroke length has a very important influence on the cutting efficiency of the machine. If the same saw blade is used to cut the material with the same number of reciprocations, the cutting efficiency of different stroke lengths will be different: the longer the stroke length, the more teeth will participate in the cutting process during each reciprocating cutting process of the saw blade, and the cutting will be more efficient. The faster; the shorter the stroke length, the fewer teeth involved in cutting, and the slower the cutting.

Saw blade: The influence of the electric reciprocating saw blade on machine cutting performance is very important. The shape, sharpness, and wear resistance of saw blade teeth are one of the decisive factors for machine cutting performance. Commonly used electric reciprocating saw blade materials are generally high-carbon steel and high-speed tool steel. For different cutting objects, the hardness requirements of the electric reciprocating saw teeth are also different.

Key Features:

Reciprocating Motion: The defining feature of this saw is its reciprocating (back-and-forth) cutting motion, achieved through a motor-driven, oscillating blade. This motion allows for efficient cutting through a variety of materials.

Adjustable Speed: Most electric reciprocating saws come with adjustable speed settings, allowing users to match the cutting speed to the material being cut. Slower speeds are typically used for cutting metal, while faster speeds are ideal for wood.

Quick Blade Changes: These saws often feature tool-less blade change systems, making it easy to swap out blades for different materials or applications. This saves time and increases productivity.

Orbital Action: Some models offer orbital action, which means the blade not only moves back and forth but also in an elliptical pattern. This feature can improve cutting efficiency and speed in certain situations.

Variable Stroke Length: Adjustable stroke lengths allow users to control the depth of their cuts, making it possible to perform both shallow and deep cuts with precision.

Comfortable Grip: Many Hand Power Brushless Compact Reciprocating Saw have ergonomic handles with comfortable grips, reducing user fatigue during extended use.

Common Uses:

Demolition Work: Hand Power Brushless Compact Reciprocating Saw are excellent tools for demolition tasks. They can quickly cut through walls, pipes, and other structures. Their ability to make plunge cuts (starting a cut in the middle of a material) is particularly valuable for demolition.

Pruning and Tree Trimming: Equipped with the right blade, a Hand Power Brushless Compact Reciprocating Saw can make pruning trees and cutting branches a breeze. This makes them handy tools for garden and yard maintenance.

Metal Cutting: Hand Power Brushless Compact Reciprocating Saw is versatile enough to cut through various metals, including pipes, rods, and metal sheets. They are commonly used in plumbing and metalworking.

Woodworking: Whether it's cutting lumber, trimming door frames, or shaping wooden pieces, reciprocating saws are valuable tools in woodworking projects. They are versatile enough to handle curved and straight cuts.

PVC and Plastic Pipe Cutting: Plumbers often use reciprocating saws to cut PVC pipes and other plastic materials quickly and cleanly.

Rescue and Emergency Services: Firefighters and rescue workers use Hand Power Brushless Compact Reciprocating Saw to cut through debris, metal, and other materials during search and rescue operations.

Masonry Work: In some cases, Hand Power Brushless Compact Reciprocating Saw can be fitted with specialized masonry blades to cut through brick, stone, or concrete.
