Description

Manufacturing method of cutting tool technical field

The invention relates to a manufacturing method of a tool, in particular to a manufacturing method of a cutting tool, so as to improve the manufacturing efficiency of the cutting tool.

Background technique

A cutting tool is a tool used for cutting in mechanical manufacturing, also known as a cutting tool. Since the vast majority of cutting tools are machine-used and basically used to cut metal materials, the term "knife" is generally understood as a metal cutting tool. However, with the development of material science, various materials have been widely used in the production and processing of products, such as engineering plastics and carbon fiber composite materials (CN203401118U). The tools can be divided into several types according to the form of the workpiece processing surface: tools for processing various outer surfaces, hole processing tools, thread processing tools, gear processing tools and cutting tools.

The structure of the working part of the tool has three types: integral type, welding type and mechanical clamping type. The overall structure is to make a cutting edge on the cutter body; the welding structure is to braze the blade to the steel cutter body; there are two mechanical clamping structures, one is to clamp the blade on the cutter body, and the other is It is to clamp the brazed cutter head on the cutter body. Large-diameter cemented carbide tools are generally made of welded structures or mechanical clamping structures.

In the cutting process, the blade becomes dull after use, and the blade needs to be replaced frequently, regrinded, or even the entire tool is replaced, resulting in a huge processing cost. As a result, an indexable tool (see Figure 1) is produced. When one blade tip is blunt, the other blade tip can be used after the blade is indexed, so that the tool can be replaced or reground to achieve continuous processing, which is not only easy to replace, but also It also greatly saves the time and cost of machining.

The inserts for indexable tools are common in shapes such as: triangle (see figure 2), quadrilateral (see figure 3), pentagon, convex triangle, circle (see figure 4) and rhombus (see figure 5) etc. The blade is clamped in the groove or the blade seat opened on the cutter body by means of screws or other flexible connections, such as: Chinese invention patent ZL03809683.8 discloses a cutting tool, including a cutter body, which has at least one concave The pocket is adapted to receive a cutting insert cartridge assembly. These indexable tools can provide sharp blades for cutting the workpiece, but it is difficult to meet the needs of extrusion (Margin) polishing of the workpiece, and other tools must be used for extrusion molding.

Chinese invention patent ZL200680033825.7 discloses a milling cutter for chip removal processing, comprising a milling cutter body with a plurality of cutting insert seats connected to the end of the milling cutter body, milling The cutter body is formed at its axially opposite ends to cooperate with the cutter attachment means, the indexable cutting insert being secured in the cutting insert seat. Each of the indexable cutting inserts has the basic shape of a truncated pyramid, the top surface of each indexable cutting insert faces the chip removal end of the milling cutter, and the main cutting edge of the indexable cutting insert is from the indexable cutting The top surface of the insert extends in a direction towards the bottom surface of the indexable cutting insert.

Chinese invention patent application 201210582143.9 discloses an indexable cutting insert with an upper surface, a The lower surface and the peripheral side surface of the pair. The indexable cutting insert main cutting edge is formed on the upper peripheral edge, and the adjacent main rake face is on the upper surface. at least two main cutting edges have different insert axial rake angles at equivalent index points along the main cutting edges, and at least two main rake faces have different The rake face profile angle of .

Chinese invention patent application 201310119151.4 discloses a cutting blade, which includes a plate-shaped blade body. The blade body is surrounded by an upper surface, a lower surface, a side surface and a recess. Each recess is arranged at intervals, and each side and each recess are connected between the upper surface and the lower surface. The recess is composed of a peripheral positioning surface and a sipe set at two opposite corners of the peripheral positioning surface. The sipe is connected to the upper surface. Or the lower surface intersects to form a main cutting edge, the sipe intersects with the side surface to form a side cutting edge, and the main cutting edge and the side cutting edge are connected to form a cutting edge group. The blade has the characteristics of simple and compact structure, strong versatility, convenient use and high cost performance.

At present, the knives used for forming machining are usually produced by pre-processing the blade into the required shape, and then welding it to the cutter body. At present, the knives used for forming machining are usually produced by pre-processing the blade into the required shape, and then welding it to the cutter body. Non-standard forming welding cannot be completed by machinery, so not only the working environment of the operators is harsh, but also the production and processing process is lengthy, and quality control is very difficult. It is also necessary to desolder and re-solder the blunt blades, or even discard the knives, and the degree of reuse is low. Low, a waste of resources and energy. Although the indexable tool realizes the reuse and quick replacement of the blade by rotating the blade at an angle, it needs to stack multiple blades to obtain the required edge shape for forming processing, which is equal to the reduced number of cutting edges, resulting in cutting Efficiency is doubled. Especially when any one of the blades becomes blunt, it is difficult to adjust the angle of a single blade to form the desired edge shape again. In addition, each side of the blade of the indexable tool is a cutting edge, which can only play a cutting role, and cannot guide the tool to support and squeeze the polishing effect, which makes the forming tool manufactured by the indexable blade only capable of cutting Used for roughing.
