specific Embodiment
[0020] In conjunction with accompanying drawing, provide specific embodiment of the present invention as follows:
[0021] Such as figure 1 As shown: the combined turning tool for processing rubber material rectangular external thread described in this embodiment is mainly composed of a left cutter 1, a right cutter 2, a positioning pin 3, an adjustment screw 4, a compression screw 5, and a combined cutter body 6 composition. The left cutter 1 and the right cutter 2 are split structures, and the left and right cutters are positioned and assembled into one by two positioning pins 3 to become an integral cutter. The installation clearance of the left and right cutters is adjusted by the adjustment screw, and the left and right cutters are symmetrically fixed on the combined cutter body by the compression screw 5. The left and right cutting knives are of welded structure, that is, the hard alloy blade is welded on the knife rod. The material of the knife rod is 45 steel, and th...

The invention discloses a combined turning tool for cutting a rectangular thread of an elastic material. The combined turning tool mainly comprises a left cutter (1), a right cutter (2), a positioning pin (3), an adjusting screw (4), a compression screw (5) and a combined tool body (6), the left cutter and the right cutter are of a split structure, symmetrically assembled together by the positioning pin and fixed onto the combined tool body through the compression screw and the adjusting screw, and the gap between the left cutter and the right cutter is adjusted by the adjusting screw. As the tool is designed into the bilaterally symmetric combined structure, a cutting edge of the left cutter is grinded into a linear cutting edge while a cutting edge of the right cutter has a 90-degree angle in order to improve rubber chip removal effect, and a cutting edge with a gap is formed when the left cutter and the right cutter are combined. As the chip removal gap is added between the left cutter and the right cutter, the problems of difficulty in chip removal, tool adhesion and the like in the process of cutting a thread of a rubber material are solved, the thread can be cut at one step, and the combined turning tool has the advantages of high cutting efficiency and fine thread precision, and is extremely suitable for cutting the rectangular thread of the rubber material.
Description
technical field [0001] The invention belongs to the technical field of metal processing tools, and mainly relates to a combined turning tool for cutting rectangular threads of elastic materials Background technique [0002] At present, when processing rubber materials, rubber materials are difficult to process due to their good elasticity, large deformation during cutting, difficult to control the processing size, poor thermal conductivity and heat resistance, low strength and high toughness. One, the tools for processing rubber materials have different specific requirements compared with the tools for processing metal materials. At present, ordinary thread turning tools are usually used to process such threads, which is difficult to remove chips, the tool and workpiece generate a lot of heat, and the workpiece is easy to Problems such as deformation and chip sticking to the knife occur, resulting in reduced processing efficiency and poor thread accuracy. For the above reas...
