Problems solved by technology

[0002] VCGX series aluminum blades are 35-degree diamond-shaped blades. Because of the large counterbore, the two blade tips are higher than the middle part, and the drop is more than 0.5mm. The density distribution after pressing is seriously uneven, and the deformation of the blank after sintering is very large. The flatness of the bottom surface is more than 0.3mm. When grinding the bottom surface, use the pressure plate to press the two knife tips and install it in the planetary disc for grinding. Due to the large deformation of the bottom surface, the two knife tips of the product at an angle of 145° after grinding out The height will be seriously out of tolerance and the scrap rate will be high
Pass rate below 80%

Abstract

The invention discloses a planetary plate clamp, a technology for machining a rhombic blade through the planetary plate clamp and the rhombic blade, and belongs to the field of hard alloy blades. The planetary plate clamp comprises a clamp body which is provided with a receding hole and a plurality of workpiece placing positions, and the workpiece placing positions are annularly arranged along the receding hole; and each workpiece placing position comprises a placing cavity and an avoiding hole, and a gap between the placing cavity and a machined part placed in the placing cavity is smaller than or equal to 0.1 mm. According to the planetary plate clamp, the gap between the placing cavity and the machined part placed in the placing cavity is controlled to be smaller than or equal to 0.1 mm, it can be guaranteed that the periphery of the workpiece and two acute-angle tool noses are positioned at the same time during grinding, and grinding errors caused by the fact that the planeness of the bottom face is out of tolerance are eliminated.

Description

technical field [0001] The invention relates to the field of cemented carbide cutting tools, in particular to a planetary disk fixture, a process for processing diamond-shaped blades by using the same, and a diamond-shaped blade. Background technique [0002] VCGX series aluminum blades are 35-degree diamond-shaped blades. Because of the large counterbore, the two blade tips are higher than the middle part, and the drop is more than 0.5mm. The density distribution after pressing is seriously uneven, and the deformation of the blank after sintering is very large. The flatness of the bottom surface is more than 0.3mm. When grinding the bottom surface, use the pressure plate to press the two knife tips and install it in the planetary disc for grinding. Due to the large deformation of the bottom surface, the two knife tips of the product at an angle of 145° after grinding out The height will be seriously out of tolerance and the scrap rate will be high. The passing rate is less...
