Description

Technical Field

[0001] The utility model relates to a hard alloy milling cutter, in particular to a split type hard alloy milling cutter with a blade that can be easily replaced, belonging to the technical field of mechanical processing equipment. Background Art

[0002] Cemented carbide milling cutter refers to a milling cutter made of cemented carbide. To understand cemented carbide milling cutter, you must first know what cemented carbide is. Cemented carbide is a powder metallurgy product made by sintering micron-sized powder of high-hardness refractory metal carbide in a vacuum furnace or hydrogen reduction furnace with cobalt or nickel and molybdenum as binders.

[0003] The patent document with the prior art publication number CN209452870U provides a split carbide milling cutter with a replaceable cutting head, including a cutter body, a connector fixedly installed on the left side of the cutter body, a cutting head movably sleeved on the outer surface of the connector, a bolt threadedly sleeved on the left end of the cutting head, the other end of the bolt threadedly sleeved on the connector, a fixed block fixedly sleeved on the outer surface of the cutter body, a fixed rod fixedly installed on the right side of the fixed block, a fixed tube movably sleeved on the right end of the cutter body, and a limited position hole opened on the left side of the fixed tube. The split carbide milling cutter with a replaceable cutting head can separate the locking rod from the limit groove by pressing the fixed handle and using the fixed handle to drive the block to push the connecting rod, and then the cutter body can be disassembled by pulling the cutter body outward, which reduces the labor intensity of the staff, improves the production efficiency of milling processing, and increases the practicality of the alloy milling cutter.

[0004] However, during the use of the existing split carbide milling cutter, during the process of processing the workpiece, the blade and the workpiece will collide, and the blade will be damaged during the collision. Since the blade is welded to the cutter body itself, when the blade is damaged, the cutter body can only be replaced, and other blades will be replaced together during the replacement process. Since it is impossible to disassemble and replace a damaged single blade, it causes a waste of carbide milling cutter resources and affects the utilization rate of the carbide milling cutter. For this reason, we propose a split carbide milling cutter that is easy to replace the blade. Utility Model Content

[0005] The purpose of the utility model is to provide a split carbide milling cutter with easy replacement of blades in order to solve at least one of the above technical problems.

[0006] The utility model achieves the above-mentioned purpose through the following technical scheme: a split carbide milling cutter that can easily replace a blade, comprising a milling cutter body, a milling cutter seat is fixedly connected to the outer side of the milling cutter body, a mounting groove is opened on one side of the milling cutter seat, a milling cutter blade is movably connected to one side of the milling cutter seat through the mounting groove, a docking rail is fixedly connected to one side of the milling cutter blade, a fixing screw is threadedly connected to the other side of the milling cutter seat, and a milling cutter sleeve is fixedly connected to the front side of the milling cutter body;

[0007] A threaded opening is provided on the front side of the milling cutter sleeve, and a threaded rod is threadedly connected to the milling cutter sleeve through the threaded opening, and one end of the threaded rod is fixedly connected to the milling cutter rod.

[0008] As a further solution of the utility model: the docking rail is movably connected to the mounting groove, and the milling cutter blade is movably connected to the milling cutter seat through the docking rail and the mounting groove.

[0011] As a further solution of the utility model: five milling blades are provided, the five milling blades are the same in size and shape, and the five outer surfaces are smooth.

[0012] As a further solution of the utility model: the milling cutter body comprises a milling cutter sleeve on the front side of the milling cutter body and a milling cutter seat on the outside of the milling cutter body, and the milling cutter sleeve and the milling cutter seat are both made of cemented carbide material.

[0013] The beneficial effect of the utility model is that through the provision of the milling cutter seat, mounting groove, milling blade, docking rail and fixing screw, when the carbide milling cutter is used, when the milling blade on the carbide milling cutter collides with the workpiece and is damaged and needs to be replaced, the staff loosens the fixing screw, and the bottom end of the fixing screw will loosen the docking rail, and then the staff pushes the milling blade outward, and the docking rail on the milling blade will slide out of the mounting groove of the milling cutter seat, and then the staff processes and replaces the docking rail on the milling blade and inserts it into the mounting groove of the milling cutter seat, and tightens the fixing screw, and the fixing screw will support the docking rail, thereby playing a fixing role, and at the same time, when the milling cutter body is damaged, the staff can rotate the milling cutter rod, and the threaded rod will move out of the threaded mouth of the milling cutter sleeve, and the milling cutter body can be replaced at this time, thereby avoiding the waste of carbide milling cutter resources, thereby improving the utilization rate of the carbide milling cutter.
