Problems solved by technology

[0004] However, in the current conventional reciprocating cutting tools, the reciprocating frequency of the reciprocating rod is generally about 3000 times / min, the rotating speed is low, the distance between the knife marks left by two adjacent cuttings is relatively large, and the surface accuracy is not high

Embodiment Construction

[0033] Such as figure 1 As shown, the present invention discloses a cutting tool, especially a reciprocating cutting tool, especially a jigsaw 10 . The jigsaw 10 includes a housing 1, and a power source is arranged in the housing 1. In this preferred embodiment, the power source is a motor 11. For convenience, the part of the housing 1 that accommodates the motor 11 is called the motor housing 110. . A reciprocating rod 12 that can be driven by a motor is provided at the front of the housing 1 , and the reciprocating rod has an axis X; a saw blade 13 is connected to the lower end of the reciprocating rod 12 . Housing 1 is also provided with a rotary drive mechanism 2 that can rotate the saw blade 13 and a knife lift drive mechanism 4 that can swing the saw blade 13. 2, the saw blade 13 can be rotated to obtain the required cutting angle; the rotary drive mechanism 2 can also rotate the saw blade 13 to obtain a wave-line cutting track; the knife-lifting drive mechanism 4 can ...

Abstract

The invention relates to a cutting tool, which comprises a housing, a power source arranged in the housing, a reciprocating lever driven by the power source, and a saw blade connected with one end of the reciprocating lever, wherein the power source drives the reciprocating lever to drive the saw blade to do reciprocating movement along the axial line direction of the reciprocating lever; and the reciprocating frequency of the reciprocating lever is more than or equal to 6000 times / min. The reciprocating frequency of the reciprocating lever of the cutting tool provided by the invention is greatly increased. The reciprocating moving frequency of the saw blade is correspondingly increased. The time interval of adjacent cutting times is shortened. Therefore, the spacing distance of the tool marks reserved by the saw blade on the surface of a workpiece may be greatly reduced. The surface cutting precision of the workpiece is greatly improved. The reciprocating frequency of the reciprocating lever is improved and the reciprocating moving speed of the saw blade is accelerated as well, so that the feeding speed of the saw blade on the workpiece can be greatly accelerated so as to improve the cutting efficiency.

Description

technical field [0001] The present invention relates to a cutting tool, in particular to a reciprocating cutting tool. Background technique [0002] Reciprocating cutting tools, such as jigsaws and reciprocating saws, are very popular power tools and are widely used in industries such as automobiles, ships, wooden molds, decoration, and leather. Straight or curved sawing of wood, metal, plastic, rubber under normal environmental conditions. [0003] Curve saws and reciprocating saws are generally driven by motors or electromagnets, and the transmission mechanism drives the working head to reciprocate to achieve the purpose of cutting. The working principles of these two tools are the same: after the high-speed rotation of the motor is decelerated by gears, The drive shaft drives the crank slider mechanism, and then the slider drives the reciprocating rod to realize reciprocating motion. The saw blade is installed in the clamping device on the reciprocating rod to reciprocat...
