Description

Technical Field

[0001] The utility model relates to the technical field of cutting tools, and particularly relates to a cutting tool on a cutting machine. Background Art

[0002] The cutting equipment involved in this application is mainly for automatically cutting objects such as paper and cloth. It includes a power device and a cutting tool, etc. The power device drives the cutting tool to move up and down, and the cutting tool cuts the object to be cut by moving up and down. There are two forms of current cutting tools. One is the conventional method in this field. Generally, the technical solution is that cutting tool edges for cutting are provided on both the working end and two side surfaces of the tool, that is, as shown in Figure 1 both the A side and the B end of Figure 2 are provided with edges. Its advantage is that the side edges can expand the range of the cut to a certain extent, and its disadvantage is that it reduces the overall strength of the tool. In the actual use process, the tool is easy to break and has a low service life. For this reason, another improved form is as shown in Figure 2 that is, no edges are provided on both side surfaces of the tool body (at the C position of ). Although it solves the problem that the tool is easy to break and extends the service life of the tool, since there are no edges on the side, it is not convenient for the tool to expand the opening at the cutting position, affecting the cutting efficiency.

[0003] The utility model provides a cutting tool, aiming to solve one of the technical problems: the technical problem that the existing cutting tool is easy to break or not convenient for cutting and expanding the opening.

[0004] Considering the above problems of the existing technology, according to one aspect disclosed by the utility model, the utility model adopts the following technical solutions:

[0005] A cutting tool, which includes:

[0006] A tool head clamping section, which is connected to the clamping mechanism of the power device part of the cutting machine;

[0007] A tool body cutting section, whose upper end is connected to the tool head clamping section. The tool body cutting section is flat. Cutting edges are provided on both sides of the upper section of the tool body cutting section, and no cutting edges are provided on both sides of the lower section of the tool body cutting section. A cutting edge is also provided at the end of the lower section of the tool body cutting section.

[0008] In order to better implement the utility model, a further technical solution is:

[0009] Further, the tool head clamping section is a cylinder.

[0010] Further, clamping grooves for easy clamping are provided on the opposite sides of the tool head clamping section.

[0011] Furthermore, the length of the cutting edge portions on both sides of the upper blade body is greater than the length of the non-cutting edge portions on both sides of the lower blade body.

[0012] Furthermore, the length of the non-cutting edge portions on both sides of the lower blade body is 2-5 millimeters.

[0013] Compared with the prior art, one of the beneficial effects of the present utility model is:

[0014] A cutting tool of the present utility model, by locally arranging a cutting edge on the side of the tool, makes the tip of the tool not easily break during work, but can also ensure the cutting efficiency of the tool. The improved solution of the present utility model has the advantages of taking into account both cutting efficiency and service life. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] In order to more clearly illustrate the embodiments of the present application document or the technical solutions in the prior art, the following will briefly introduce the drawings required for use in the description of the embodiments or the prior art. Obviously, the drawings in the following description are only references to some embodiments in the present application document.

[0021] The following further describes the present utility model in detail with reference to the embodiments, but the embodiments of the present utility model are not limited thereto.

[0022] See Figure 3As shown in the figure, a cutting tool includes a tool head clamping section 1 and a tool body cutting section 2; the tool head clamping section 1 is connected to the clamping mechanism of the power device part of the cutting machine; the upper end of the tool body cutting section 2 is connected to the tool head clamping section 1, the tool body cutting section 2 is flat, cutting edges 3 are arranged on both sides of the upper tool body 4 of the tool body cutting section 2, the lower tool body 5 of the tool body cutting section 2 is arranged without cutting edges on both sides, and a cutting edge 3 is also arranged at the end of the lower tool body 5 of the tool body cutting section 2. Due to the cutting edges 3 being arranged on both sides of the upper tool body 4 of the tool body cutting section 2 in this embodiment of the cutting tool, when the cutting tool is pulled back after cutting downwards and the object to be cut is running horizontally, the cutting edges 3 on the side of the upper tool body 4 of the tool body cutting section 2 will further cut the cutting opening, thereby improving the cutting efficiency. And because the lower tool body 5 of the tool body cutting section 2 is arranged without cutting edges on both sides, that is, it is still a tool body with a certain thickness, it has greater strength, making the cutting tool not easily broken and extending the service life of the cutting tool. Through the technical solution of this embodiment, not only the service life of the tool is extended, but also the cutting efficiency of the tool can be improved.

[0023] In the above-mentioned embodiment, for the solution where the cutting edges 3 are arranged on both sides of the upper tool body 4, after one side of the cutting edge 3 becomes blunt, the installation direction of the cutting tool can be changed, and the other side of the cutting edge 3 can be made to face the object to be cut, so as to make the best use of the cutting tool to the greatest extent.

[0024] Generally speaking, the tool head clamping section 1 is a cylinder, and grooves 6 for easy clamping can be arranged on the opposite sides of the tool head clamping section 1, so as to facilitate the fixed connection between the tool head clamping section 1 and the power device part of the cutting equipment.

[0025] The length of the part of the cutting edges 3 on both sides of the upper tool body 4 can be greater than the length of the part without cutting edges on both sides of the lower tool body 5.

[0026] The length of the part without cutting edges on both sides of the lower tool body 5 can preferably be 2 - 5 millimeters.

[0027] In summary, for the cutting tool of the present utility model, compared with the prior art, by locally arranging cutting edges on the side of the tool, the tool tip is not easily broken during work, but can also ensure the cutting efficiency of the tool. The improved solution of the present utility model has the advantages of taking into account both cutting efficiency and service life.
