A sawing-type oscillating ultrasonic cutting knife

Abstract

This utility model discloses a sawing-type oscillating ultrasonic cutting tool, including a tool head and a cutting blade mounted on the tool head. The cutting blade comprises a mounting portion mounted on the tool head and a cutting portion inclined to the axis of the tool head, allowing the cutting blade to perform sawing-type oscillating cutting in response to ultrasonic vibrations. By arranging the cutting portion of the cutting blade inclined to the axis of the tool head, this utility model allows the cutting blade to move back and forth when the tool head drives it to vibrate, thus enabling the cutting portion to perform sawing-type oscillating cutting. This results in low cutting resistance and improved ultrasonic cutting effect.

Description

Technical Field

[0001] This utility model relates to an ultrasonic cutting knife, specifically a sawing-type oscillating ultrasonic cutting knife. Background Technology

[0002] In existing ultrasonic cutting tools, the tool head is generally vertically positioned, and the cutting blade is also vertically mounted on the tool head. When the tool head drives the cutting blade to cut the workpiece, the tool head causes the cutting blade to vibrate up and down. The cutting blade then cuts the workpiece through this up-and-down vibration. This method results in significant resistance during cutting and poor cutting performance. Therefore, a sawing-type oscillating ultrasonic cutting tool is proposed. Utility Model Content

[0003] The purpose of this invention is to provide a sawing-type oscillating ultrasonic cutting tool to solve the above problems.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a sawing-type oscillating ultrasonic cutting tool, comprising a tool head and a cutting blade mounted on the tool head; characterized in that the cutting blade includes a mounting portion mounted on the tool head and a cutting portion inclined to the axis of the tool head, so that the cutting blade performs sawing-type oscillating cutting with ultrasonic vibration.

[0005] A further preferred embodiment includes a shrinkage groove on the tool head and a shrinkage hole on the tool head that communicates with one end of the shrinkage groove to reduce stress.

[0006] A further preferred embodiment includes a positioning groove provided on the tool head for mounting the cutting blade and for defining the position of the cutting blade mounted on the tool head.

[0007] The beneficial effects of this utility model are as follows: by setting the cutting part of the cutting blade at an angle to the axis of the tool head, the cutting blade moves back and forth when the tool head drives the cutting blade to vibrate, thereby enabling the cutting part to perform a sawing-like oscillating cut, resulting in low cutting resistance and improved ultrasonic cutting effect.

[0010] The following description, in conjunction with the accompanying drawings, further illustrates the sawing-type oscillating ultrasonic cutting tool of this utility model.

[0011] It should be noted that all directional indicators such as up, down, left, right, front, back, etc. in the embodiments of this utility model are only used to explain the relative positional relationship and movement of the components in a specific posture as shown in the attached figure. If the specific posture changes, the directional indicator will also change accordingly.

[0012] In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixing," etc., should be interpreted broadly; for example, "fixing" can mean a fixed connection, a detachable connection, or an integral part; it can also mean a mechanical connection, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0013] See Figures 1-3 As shown, a sawing-type oscillating ultrasonic cutter includes a tool head 1 and a cutting blade 2 fixedly mounted on the tool head 1 by screws or bolts or other fasteners; characterized in that the cutting blade 2 includes a mounting portion 21 mounted on the tool head 1 and a cutting portion 22 that is inclined to the axis of the tool head 1 so that the cutting blade 2 performs sawing-type oscillating cutting with ultrasonic vibration. By setting the cutting part 22 of the cutting blade 2 at an angle to the axis of the tool head 1, the cutting blade 2 moves back and forth when the tool head 1 drives the cutting blade 2 to vibrate, thereby making the cutting part 22 perform a sawing oscillating cut during cutting, thus improving the ultrasonic cutting effect.

[0014] In one embodiment, the tool head 1 is further provided with a shrinkage groove 3 and a shrinkage hole 31 provided on the tool head 1 and communicating with one end of the shrinkage groove 3 to reduce stress; the shrinkage groove 3 enables the front end of the tool head 1 to shrink and press the cutting blade 2 when the cutting blade 2 is fixed.

[0015] In one embodiment, a positioning groove 32 is provided on the tool head 1 for mounting the cutting blade 2 and for defining the position of the cutting blade 2 mounted on the tool head 1; the positioning groove 32 defines the position of the cutting blade 2 mounted on the tool head 1, which facilitates the installation and positioning of the cutting blade 2.

[0016] When using this utility model: when cutting the object, the tool head 1 is positioned horizontally or at an angle to the object being cut. The tool head 1 drives the cutting blade 2 to vibrate laterally, which in turn drives the cutting part 22 of the cutting blade 2 to perform a sawing motion. The cutting blade 2 performs a lateral sawing motion when cutting the object.

[0017] The scope of protection of this utility model is not limited to the above embodiments and their variations. Conventional modifications and substitutions made by those skilled in the art based on the content of these embodiments are all within the scope of protection of this utility model.
