Embodiment 1

[0058] Such as figure 2 , image 3 As shown, a kind of arc-shaped blade grinding device of this embodiment mainly completes the figure 1 The grinding process of the arc-shaped blade blade shown in this circular-arc-shaped blade has a circular mounting hole 710 at one end of the knife body 700 for installing the blade on the corresponding cutting equipment, and the knife body 700 is close to the mounting hole 710 There is a positioning hole 720 at the position of the blade, which is used for positioning when installing the blade; the other two sides of the blade body 700 are the blade side 730 and the blade back side 740 respectively, both of which are arc-shaped, but not concentric, and gradually retract toward the front end of the blade. narrow, and there are knife teeth 731 distributed on the arc segment of the blade side 730, and the front and back sides of the knife teeth 731 are blade slopes 732. In actual production, the blade slope 732 needs to be ground, and the blad...

Embodiment 2

[0070] The grinding method of a kind of circular-arc-shaped blade edge of the present embodiment, it adopts the grinding device among the embodiment 1 to such as figure 1 The arc-shaped insert shown is ground, grinding the bevel 732 of the edge. The specific steps of the operation will be described in detail below.

[0071] 1. Blade installation

[0072] Install the arc-shaped blade to be ground on the workbench assembly 400 . Specifically: first, align the mounting hole 710 and the positioning hole 720 of the arc-shaped blade with the fixed shaft 421 and the positioning pin 422 on the turntable 420 respectively, put down the arc-shaped blade, and position it; then, place the pressing spring Sleeve on the fixed shaft 421, tighten the compression nut, and fix the arc-shaped blade, and then complete the installation of the blade.

[0073] 2. Grinding angle adjustment

[0074] First, select three grinding wheels 330, which are respectively rough grinding wheels, semi-finishin...

Abstract

The invention discloses a circular-arc-shaped cutter blade edge grinding method, and belongs to the technical field of cutter grinding. The method comprises the following steps that 1, a to-be-groundcircular-arc-shaped cutter blade is installed on a workbench assembly at first; 2, a grinding wheel is selected and installed on a grinding wheel assembly, and the grinding angle of the grinding wheelis adjusted through an angle adjusting mechanism; 3, the grinding height of the grinding wheel is adjusted through a lifting mechanism; and 4, the grinding wheel assembly is driven through a swing mechanism, so that the grinding wheel conducts grinding machining on the inclined face of a cutting edge of the circular-arc-shaped cutter blade. The qualified cutting edge of the cutter blade is obtained through rough grinding, semi-finish grinding and grinding. According to the circular-arc-shaped cutter blade edge grinding method, the circular-arc-shaped cutting edge face of the circular-arc-shaped cutter is ground through a circular-arc-shaped cutting edge grinding device, the technical requirements for operators are greatly lowered, the high-quality cutting edge of the circular-arc-shaped cutter blade can be machined out efficiently, the arc shape of the ground cutting edge face is good, and the angle consistency of the cutting edge is good.

Description

technical field [0001] The invention belongs to the technical field of tool grinding, and relates to a method capable of grinding the edge of an arc-shaped knife, more specifically, to a method for grinding the edge of an arc-shaped blade. Background technique [0002] Grinding is widely used and is one of the main methods for precision machining of machine parts. A grinder is a machine tool that uses abrasive tools, such as grinding wheels, to grind the surface of a workpiece. The grinding machine can process materials with higher hardness, such as hardened steel, cemented carbide, etc.; it can also process brittle materials, such as glass and granite. The grinding machine can be used for grinding with high precision and small surface roughness, as well as high-efficiency grinding, such as powerful grinding. [0003] In the production process of alloy steel or ceramic blades, grinding is an essential and important process. Only rough grinding and fine grinding can produce...
