Description

Machine clip type flexible resharpenable turning tool

technical field

The utility model relates to a lathe tool, in particular to a machine clip type flexible regrindable turning tool.

Background technique

Turning tools are the key tools for turning. At present, welding turning tools, machine clamp regrind turning tools and machine clamp indexable non-regrind turning tools are commonly used. The welding turning tool is to weld the hard alloy knife block on the head of the tool holder. Because the welding tool is welded by heat, the blade will produce thermal cracks, which will reduce the hardness and cutting performance, thereby reducing the durability of the hard alloy blade. When sharpening the knife, it is necessary to sharpen the hard alloy knife block and the knife rod. The sharpening time is long, and the phenomenon of "burning the knife" is prone to occur, and the material of the knife rod is wasted. The indexable non-regrinding turning tool of the machine clamp overcomes these defects of the welding tool, but loses the regrinding function of the tool. During its working process, after the cutting edge of the blade wears out, it can only switch to another cutting edge to continue working. When all the cutting edges are indexed, the blade can no longer be used. At this time, the blade body is only worn out by several cutting edges, so the utilization rate of the blade of the indexable machine clamping tool is very low, wasting a large amount of cemented carbide materials. When sharpening the machine clamp regrinding turning tool, the hand is very close to the grinding wheel, which is prone to safety accidents.

Contents of the invention

The purpose of this utility model is to solve the problems existing in the prior art, and to provide a clamp-type flexible regrindable turning tool that can improve the utilization rate of cemented carbide blades, facilitate sharpening, and reduce vibration during cutting .

The scheme of the utility model is as follows: a machine-clamp type flexible regrindable turning tool, including a tool bar and a hard alloy blade installed on the tool head, is characterized in that a buffer groove is opened at the front end of the tool bar. A long slot for installing a hard alloy blade is opened on the head of the front end, and a pressing plate for fixing the hard alloy blade is installed on the head.

The surface of the pressing plate corresponding to the rake surface of the cemented carbide insert is an inclined surface or an arc surface.

The above-mentioned pressing plate is fixedly installed on the cutter head by bolts.

The features of the utility model are: 1. Since there is a long groove for installing the hard alloy blade on the cutter head, the hard alloy blade is fixed on the cutter head through the pressing plate, which can effectively improve the utilization rate of the cemented carbide blade; 2. There is a buffer groove at the front end of the tool bar, which can effectively reduce the problem of reduced processing quality caused by vibration during turning; 3. When sharpening the tool, only need to sharpen the flank of the carbide tool head, which can be Effectively improve the efficiency of tool sharpening.

Fig. 2 is a structural schematic diagram of the utility model cutter bar.

Detailed ways

As shown in Figures 1 and 2, a buffer groove 6 is opened at the front end of the cutter bar 4, and a long groove 7 for installing a hard alloy blade is opened on the cutter head 3, and the hard alloy blade 5 is installed in the long groove through the pressure plate 1. In 7, in order to facilitate breaking during the turning process, the surface corresponding to the rake face of the pressing plate and the cemented carbide insert is an inclined plane or a circular arc surface, which can improve the breaking effect during cutting. One or two screw holes 8 are opened on the cutter head. When the turning tool is large, two bolts 2 can be used to fix the pressure plate 1 on the cutter head. When the turning tool is small, one bolt 2 can be used to fix the pressure plate on the cutter head on the head.

When the carbide tip needs to be sharpened, only the flank face of the carbide tip needs to be sharpened instead of the rake face of the carbide tip, which can effectively improve work efficiency.
