Cutting blade

Abstract

The utility model discloses a cutting blade which comprises a cutter body, namely a triangular prism, and the center of the triangular prism is provided with a fixing hole formed along the axial direction; the edge tip is thinned in the axial direction to form a cutting edge; the top end of the cutting edge is formed by intersecting the top ends of two arcs with different diameters, the radius of the first arc ranges from 0.75 mm to 0.85 mm, the radius of the second arc ranges from 0.35 mm to 0.45 mm, and the two arcs are both quarter arcs; the bottom end of the first arc is connected with the first side face of the cutting edge. The cutting edge is provided with the two tangent planes with the diameter smaller than that of a groove-shaped arc angle of an existing seaming wheel, so that an arc groove with a certain proportion larger than that of the arc can be cut out when machining is conducted according to a groove-shaped track, and the machining efficiency is improved. Therefore, most groove types in the current market can be generally processed without replacing the blade in the process.

Description

Technical Field

[0001] The utility model relates to the field of mechanical processing, in particular to a cutting blade. Background Art

[0002] Sealing wheel, also known as sealing roller, is a kind of mechanical spare parts that must be used on can sealing machinery and equipment. It is used to evenly seal the bottom or can cover of three-piece cans (bottom, body, cover) and two-piece cans (usually aluminum cans, only can body and can cover) onto the can body to achieve the final use purpose. This spare part is widely used in various iron cans, iron drums, beverage cans, beer cans and other packaging equipment industries and beer and beverage manufacturing industries.

[0003] In actual use, different can bodies have different thicknesses of iron or aluminum sheets, and the seaming wheel must have a corresponding groove for seaming. In the past, the seaming wheel groove needed to be processed with a profiling tool that was consistent with its groove. Therefore, different grooves required corresponding profiling tool heads. The tool reserve was large, difficult to distinguish, and easy to confuse. Once the tool was worn, it could not accurately process the precise groove, resulting in the scrapping of the workpiece. Utility Model Content

[0004] The utility model aims to solve at least one of the technical problems in the above-mentioned technology to a certain extent. To this end, the utility model aims to provide a cutting blade with a specific bending angle at the cutting end so that a cutting tool can process various groove types of the seaming wheel.

[0005] To achieve the above-mentioned purpose, an embodiment of the utility model proposes a cutting blade, comprising: a blade body: a triangular prism with a fixing hole formed axially in the center; thinned axially at the edge tip to form a cutting edge; a cutting edge: the top end is formed by the intersection of the top ends of two arcs with different diameters, wherein the radius of the first arc is 0.75mm~0.85mm, the radius of the second arc is 0.35mm~0.45mm, and the two arcs are both quarter arcs; the bottom end of the first arc is connected to the first side surface of the cutting edge; the bottom end of the second arc is connected to the second side surface of the cutting edge, and the first side surface and the second side surface are parallel.

[0006] According to a cutting blade of an embodiment of the utility model, since the cutting edge has two cut surfaces with diameters smaller than the arc angle of the existing seaming wheel groove, an arc groove larger than a certain proportion of the arc can be cut when processing according to the groove trajectory, so most of the grooves currently on the market can be processed without replacing the blade during processing.

[0007] In addition, a cutting blade according to the above embodiment of the utility model may also have the following additional technical features:

[0008] Optionally, the ratio of the radii of the first arc to the second arc is 2:1.

[0009] Optionally, the first arc radius is 0.8 mm, and the second arc radius is 0.4 mm.

[0010] Optionally, the first side surface is an end surface of the blade body.

[0011] Optionally, a concave transition section is formed at the connection between the cutting edge and the blade body along the radial direction of the blade body. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0023] Since the cutting edge of the utility model has two cut surfaces with diameters smaller than the arc angle of the existing seaming wheel groove, an arc groove larger than a certain proportion of the arc can be cut when processing according to the groove trajectory, so most grooves currently on the market can be processed universally without the need to replace the blade during processing.

[0024] In order to better understand the above technical solution, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0025] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0026] Figures 1 to 3 A cutting blade according to an embodiment of the utility model comprises:

[0027] Cutter body 1: a triangular prism with a fixing hole 11 formed in the center along the axial direction; when in use, this embodiment is fixed to the turning tool rod by a fastener, and the movement of the turning tool rod drives the workpiece to be processed; the workpiece rotates, and its rotation direction is in the same plane as the radial direction of the cutter body 1, so the workpiece can be cut, and the cutter body 1 is thinned axially at the edge tip to form a cutting edge 2; the thickness of the cutting edge 2 is slightly smaller than the inner width of the groove of the crimping wheel 100, so that the cutting edge 2 can penetrate into the groove body for processing.

[0028] Cutting edge 2: The top end is formed by the intersection of the top ends of two arcs with different diameters, wherein the radius of the first arc 21 is 0.75 mm to 0.85 mm (see Figure 3 The radius of the second arc 22 is 0.35 mm to 0.45 mm (see Figure 3 R2), optionally, the ratio of the radius of the first arc 21 and the second arc 22 is 2:1, and both arcs are quarter arcs. Through the above parameters, the processing parameters of the cutting edge 2 of various embodiments of the utility model can be determined.

[0029] Preferably, the radius of the first arc 21 is 0.8 mm, and the radius of the second arc 22 is 0.4 mm, because on the market, most of the grooves of the existing crimping wheel 100 have R1' and R2' (see Figure 5 ) has a radius between 1 mm and 1.3 mm and between 0.45 mm and 0.6 mm. Therefore, through the design of R1 and R2, the inner arc portion of the groove of most existing seaming wheels 100 can be processed.

[0030] The bottom end of the first arc 21 is connected to the first side surface 23 of the cutting edge 2 ; the bottom end of the second arc 22 is connected to the second side surface 24 of the cutting edge 2 , and the first side surface 23 and the second side surface 24 are parallel.

[0032] Optionally, the first side surface 23 is the end surface of the blade body, which facilitates the processing of the blade and serves as a reference surface when the blade processes a workpiece.

[0033] Optionally, a concave transition section 3 is formed at the connection between the cutting edge 2 and the cutter body 1 along the radial direction of the cutter body 1. This method allows the cutting debris during processing to be discharged smoothly.
