Fretsaw with self-adjusting feed amount

Abstract

The invention relates to the technical field of material cutting, and discloses a fretsaw with the self-adjusting feed amount. When the contact area of a wire saw and a cutting material is reduced, the self elastic force of a stress spring is smaller than the acting force of the material on the wire saw at the moment, so that a balance cutting device integrally moves towards the right side in Figure 2, and the cutting speed is accelerated; the fretsaw can automatically adjust the cutting speed according to the contact area of the wire saw and the material, so that the cutting efficiency is maximized; meanwhile, the wire saw is in a stable state; the fretsaw enables the wire saw to be in the optimal work state while ensuring the cutting efficiency; the service life of the wire saw is prolonged; and the use cost of the fretsaw is reduced. In addition, a stable stroke direction is given to the balance cutting device by an outer bin shell, and meanwhile, the amplitude of vibration of the balance cutting device driven by the wire saw during cutting is also reduced, so that the processing precision and stability of the fretsaw are improved.

Description

technical field [0001] The invention relates to the technical field of material cutting, in particular to a feed rate self-adjusting wire saw. Background technique [0002] A wire saw is a tool that uses a wire saw to cut materials. It is usually driven by a power machine or a hydraulic machine. The initial wire saw is usually limited by the material of the wire saw and can only cut wood. With the advancement of science and technology, today's wire saws have higher strength, can cut various materials such as steel, concrete, wood, etc., and realize one-way rotation through the drive of the power machine, making the cutting surface smoother, making it usually also It is used in some high-end manufacturing industries, such as silicon element cutting or stone cutting. [0003] Although the wire saw has many advantages, the strength of the wire saw is lower than that of the traditional circular saw. In the face of some hard materials with irregular shapes, the cutting surface b...

Problems solved by technology

[0004] Aiming at the shortcomings in the use of the existing wire saw proposed in the background technology, the present invention provides a wire saw with self-adjusting feed rate, which has the advantage of automatically adjusting the cutting force according to the contact area between the wire saw and the cutting surface. It solves the problem that the traditional wire saw cannot adjust the cutting force of the wire saw so that the force received by the wire saw fluctuates continuously and easily leads to breakage
